Description

CHARGE PLANNING SYSTEM, CHARGE PLANNING DEVICE, CHARGE PLANNING METHOD, AND PROGRAM

This application claims priority based on Japanese Patent Application No. 2011-194058 filed on September 6, 2011, and all the contents described in the Japanese application are incorporated herein by reference.

The present invention relates to a charging planning system, a charging planning device, a charging planning method, and a program.

In recent years, due to environmental considerations, rather than using an internal combustion engine that uses gasoline or the like as a power source, a mobile body that uses battery power as a power source (for example, an electric vehicle, hereinafter referred to as an electric vehicle) Are becoming popular. Simultaneously with the popularization of electric vehicles, charging facilities (also called “charging stations”, “charging stands”, etc.) for charging batteries of electric vehicles have been prepared.

A system that moves from home to the nearest station by electric car, parks it in a parking lot equipped with a charging facility, and then travels to a destination such as a company using transportation such as railway (for example, “Park and Ride” ") Is expected to increase.

The charging facility has one or more parking spaces and can charge an electric vehicle parked in each parking space. For example, the charging facility can charge the electric vehicle by connecting a charging terminal provided in each parking space and the parked electric vehicle via a cable or the like. In addition, by utilizing a technology called a non-contact power transmission method (hereinafter referred to as wireless power feeding), an electric vehicle can be charged from a coil-type charging facility embedded in the ground without using a cable. .

Depending on the charging facility, there is an upper limit on the amount of power supply for a certain period of time, and it may not be possible to charge multiple electric vehicles at the same time. For example, when using a power generation method that utilizes natural energy, such as solar power generation or wind power generation, as a means of supplying power to the charging facility, or for leveling power consumption by region or time unit, A case where the company sets an upper limit on the power supplied to the charging facility (also called a smart grid) is considered. In such a case, the charging facility sequentially charges the electric vehicle in a predetermined order. For example, claim 1 and paragraph 0033 of Patent Document 1 describe a system that rearranges the order of electric vehicles waiting to be charged using a scheduled departure time as a key.

JP 2011-083165 A

By the way, even if the electric vehicle enters the charging facility and starts charging with a charging schedule corresponding to the set scheduled delivery time, the actual delivery time is likely to change thereafter. That is, there is a high possibility that the parking time from the entry time to the exit time varies. For example, in a system such as Park and Ride, if the time to return from the destination is advanced or delayed, the actual delivery time is accordingly advanced or delayed from the original scheduled delivery time. That is, there is a difference between the initial scheduled parking time and the actual parking time.

∙ If there is a discrepancy between the initial scheduled parking time and the actual parking time, user convenience may be reduced. For example, if the actual delivery time of a certain user is earlier than the original scheduled delivery time, if charging is performed according to the original charging schedule, there is a risk that the user may not be charged sufficiently at the time of delivery. There is.

Therefore, if the time as close as possible to the actual parking time is ascertained in advance and a charging schedule can be generated accordingly, charging that satisfies the user can be performed, and convenience for the user can be improved. In addition, since the length of the parking time varies depending on the user, if the charging schedule can be generated according to the length of the parking time so that sufficient charging for the user can be performed at the time of delivery, the charging that satisfies the user is performed. This can improve user convenience.

Therefore, an object of the present invention is to generate a charging plan according to the length of the parking time and the variation in the length of the parking time.

The present application includes a plurality of means for solving the above-mentioned problems. An example of the means is as follows.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic diagram showing an example of a charging plan system according to an embodiment of the present invention.

First, the outline of the charging plan system 1 will be described.

The charging plan system 1 includes a charging plan management server 10, a user terminal 20, and a charging facility management server 30. The charging plan management server 10, the user terminal 20, and the charging facility management server 30 can communicate with each other via the network 40. The charging facility management server 30 is included in the charging facility 3. There may be a plurality of charging facilities 3.

The charging plan management server 10 is a device that manages a charging plan for each charging facility 3. The charging plan management server 10 receives information related to the electric vehicle 355 that has entered the parking lot 354 of the charging facility 3 from the charging facility management server 30, and based on this information, from the entry time of the electric vehicle 355 to the scheduled delivery time. Generate a charging schedule.

The charging plan management server 10 generates a charging schedule that preferentially charges the electric vehicle 355 of the user whose time from the entry time to the scheduled delivery time is short. In addition, a charging schedule is generated in which the electric vehicle 355 of a user who tends to have an actual shipping time earlier than the scheduled shipping time is preferentially charged.

Also, the charging plan management server 10 receives location information from the user terminal 20, changes the scheduled delivery time based on the location information, and updates the charging schedule. In addition, the charging plan management server 10 receives a request for changing the scheduled delivery time from the user terminal 20 and updates the charging schedule.

Further, the charging plan management server 10 instructs the charging facility management server 30 to execute charging based on the generated charging schedule.

The user terminal 20 is a terminal used by a user of the charging facility 3 such as a driver of the electric vehicle 355, and transmits various information to the charging plan management server 10. The user terminal 20 transmits, to the charging plan management server 10, a request for changing the scheduled delivery time of the electric vehicle 355 that has entered the charging facility 3, the location information of the user terminal 20, and the like. The user terminal 20 may communicate with the charging facility management server 30. The user terminal 20 is, for example, a mobile phone, a smartphone, a PC (Personal Computer), a navigation device, or the like.

The charging facility management server 30 is a device that manages the charging facility 3. The charging facility management server 30 acquires information on the electric vehicle 355 stored in the parking lot 354 from the charging terminal 353 via the communication device 352 or accepts it via an input device (not shown), and the charging plan management server 10 Send to. Further, the charging facility management server 30 controls the changeover switch 351 via the communication device 352 based on an instruction from the charging plan management server 10 to switch the power supply destination (electric vehicle 355 to be charged). The charging facility management server 30 may communicate with the user terminal 20.

The charging facility 3 includes a charging device 350, a changeover switch 351, a communication device 352, a plurality of charging terminals 353, and a parking lot 354 including a plurality of parking spaces, in addition to the charging facility management server 30.

In this embodiment, it is assumed that the charging facility 3 cannot charge a plurality of electric vehicles at the same time. Therefore, the charging facility 3 has a mechanism for switching the electric vehicle to be charged.

The charging device 350 outputs power to the charging terminal 353 installed in the parking space via the changeover switch 351. It is conceivable that the charging device 350 supplies power by directly connecting to the power grid, or supplies power using solar power generation, wind power generation, or the like. It is assumed that there is an upper limit on the output power because there is a restriction on the power supplied from the electric power company or an upper limit of the power generation amount.

The changeover switch 351 selectively switches the output destination of the power output from the charging device 350 to any one of the charging terminals 353. The changeover switch 351 receives a control signal instructing selection of the charging terminal 353 from the charging facility management server 30 via the communication device 352, and performs switching in accordance with the selection instruction.

The communication device 352 receives the control signal from the charging facility management server 30 and outputs it to the changeover switch 351. The communication device 352 is connected to each charging terminal 353, receives information related to the electric vehicle 355 transmitted from each charging terminal 353, and transmits the information to the charging facility management server 30.

The charging terminal 353 is installed for each parking space of the parking lot 354. The charging terminal 353 includes, for example, a charging cable, and is connected to the electric vehicle 355 through the charging cable. The charging terminal 353 supplies the electric power output from the charging device 350 via the changeover switch 351 to the electric vehicle 355 via the charging cable. Note that the charging terminal 353 may include a coil or the like instead of the charging cable and may be installed in the ground of each parking space to charge the electric vehicle 355 by wireless power feeding.

The charging terminal 353 is connected to the communication device 352. In this embodiment, the charging cable can communicate in addition to supplying power. Therefore, the charging terminal 353 can receive various types of information from the electric vehicle 355 via the charging cable, and can transmit them to the charging facility management server 30 via the communication device 352. Charging terminal 353 may include an input device (not shown), and may receive information related to electric vehicle 355 via the input device.

The above-described charging plan management server 10, user terminal 20, and charging facility management server 30 can be realized by a computer 50 as shown in FIG.

The computer 50 includes an arithmetic device 500 such as a CPU, a main storage device 510 such as a RAM, a communication device 520 such as a network interface that performs wired communication or wireless communication, an auxiliary storage device 530 such as an HDD, a keyboard, a mouse, An input device 540 such as a touch panel and a display device 550 such as an LCD or an organic EL display are provided.

The computer 50 used for the user terminal 20 includes, for example, a GPS (Global Positioning System) receiver (not shown) in order to calculate position information. For example, the GPS receiver receives a signal from a GPS satellite, and measures the distance between the user terminal 20 that is a moving body and the GPS satellite and the rate of change of the distance with respect to three or more satellites. Current position information of the user terminal 20 is measured.

Next, the details of the charging plan system 1 will be described.

In this embodiment, when the charging terminal 353 is connected to the electric vehicle 355 by the user's work, the charging time is specified as the warehousing time. In addition, when the electric vehicle 355 is connected, vehicle identification information for specifying the electric vehicle and the state of charge of the battery (for example, a value indicating the ratio of the charge amount to the charge capacity) are acquired from the electric vehicle 355. . In addition, the charging terminal 353 transmits the parking space identification information, the warehousing time, the vehicle identification information, and the charging state to the charging facility management server 30. The charging terminal 353 may acquire the charging state in real time or periodically and transmit it to the charging facility management server 30.

After the electric vehicle 355 is connected to the charging terminal 353, the charging facility management server 30 identifies the user for the electric vehicle 355 connected by the user via the input unit 310 by the user's operation. The identification information and the scheduled delivery time of the electric vehicle 355 are received. Moreover, you may receive the designated charge amount which shows the quantity (for example, X% of charge capacity 100%) which a user wants to charge as needed of a user.

In this way, the charging facility management server 30 for each charging terminal 353 (for each parking space), the user identification information, the vehicle identification information, the warehousing time, the scheduled evacuation time, and the designated charging of the entrapped electric vehicle The quantity and state of charge can be acquired and stored.

In addition, when the connection of the electric vehicle 355 is disconnected by the user's work, the charging terminal 353 specifies the disconnected time as the delivery time. The charging terminal 353 transmits the parking space identification information, the departure time, and the vehicle identification information to the charging facility management server 30.

Thus, the charging facility management server 30 can acquire and store the delivery time of the delivered electric vehicle for each charging terminal 353 (for each parking space).

Of course, the above processing procedure at the time of loading and unloading is an example, and is not limited to the above. For example, the scheduled delivery time may be input from the charging terminal 353. The scheduled delivery time may be input from the user terminal 20 and transmitted to the charging facility management server 30. It may be input from the user terminal 20 and transmitted to the charging terminal 353.

In addition, instead of allowing the user to input the scheduled delivery time, the user may input the parking time scheduled by the user. In this case, for example, the charging facility management server 30 includes, for the electric vehicle 355 connected by the user via the input unit 310 by the user's operation, user identification information for identifying the user, and the electric vehicle 355. Accept parking time. The charging facility management server 30 calculates and stores the scheduled delivery time by adding the parking time received to the current time. The charging facility management server 30 may transmit the parking time to the charging plan management server 10, and the charging plan management server 10 may calculate the scheduled delivery time.

Further, the warehousing time is not limited to the time when the electric vehicle 355 is connected to the charging terminal 353, and may be another time. For example, the time when the electric vehicle 355 passes through the gate of the parking lot 354 and enters the parking lot may be used. Further, the delivery time is not limited to the time when the electric vehicle 355 is disconnected from the charging terminal 353, and may be another time. For example, it may be the time of passing through the gate and going out of the parking lot.

The user terminal 20 includes a communication unit 200, an input unit 210, a display unit 220, a control unit 230, a storage unit 240, and a position information calculation unit 250.

The display unit 220 is realized by, for example, the display device 550 (see FIG. 2). The storage unit 240 stores various information used for processing by the control unit 230. The storage unit 240 is realized by, for example, the auxiliary storage device 530 (see FIG. 2).

The location information calculation unit 250 calculates the current location information of the user terminal. The position information calculation unit 250 is, for example, the above-described GPS receiver (not shown). Of course, the position information calculation unit 250 may acquire position information from a radio base station or the like via the communication unit 200, for example. The calculated or acquired current location information is stored in the storage unit 240, for example.

The control unit 230 performs processing for controlling the other units and controlling the user terminal 20. For example, the control unit 230 causes the arithmetic device 500 (see FIG. 2) to read and execute a predetermined program stored in the auxiliary storage device 530 (see FIG. 2) to the main storage device 510 (see FIG. 2). Realized.

The control unit 230 receives, for example, an instruction to transmit current location information to the charging plan management server 10 from the user via the input unit 210. The information of the charging plan management server 10 that is the transmission destination may be input by the user, for example, or may be input by photographing a bar code representing the transmission destination with a camera or the like. The barcode representing the transmission destination may be displayed by the charging facility management server 30 or the charging terminal 353, for example.

When receiving an instruction to transmit the current location information, the control unit 230 causes the position information calculation unit 250 to calculate the current location information, and includes information including the calculated current location information, the user identification information, and the parking space identification information. The data is transmitted to the charging plan management server 10 via the communication unit 200. For example, the user identification information and the parking space identification information may be input by the user, or may be input by photographing a bar code representing the identification information with a camera or the like. The barcode representing the identification information may be displayed by the charging facility management server 30 or the charging terminal 353, for example.

In addition, the control unit 230 receives an instruction from the user via the input unit 210, for example, to transmit an advance request for a scheduled delivery time to be described later to the charging plan management server 10. The control unit 230 receives the scheduled delivery time and the designated charge amount, and sends information including the scheduled delivery time, the designated charge amount, the user identification information, and the parking space identification information via the communication unit 200. To the charging plan management server 10. For example, the user identification information and the parking space identification information may be input by the user, or may be input by photographing a barcode or the like with a camera or the like.

The charging plan management server 10 includes a control unit 100, a communication unit 120, and a storage unit 130.

The communication unit 120 transmits and receives data via the network 40. The communication unit 120 is realized by, for example, the communication device 520 (see FIG. 2).

The storage unit 130 stores various information used for processing related to the charging plan by the control unit 100. The storage unit 130 is realized by the auxiliary storage device 530, for example. The storage unit 130 stores a parking lot usage information DB (Data Base) 131, a parking lot history information DB 132, and a charging plan information DB 133.

The parking lot usage information DB 131 stores usage information indicating the usage status for each parking space. The parking lot use information DB 131 is realized by a table as shown in FIG. 3, for example.

The parking space use information DB 131 stores in advance a parking space ID 1311 that is identification information for each parking space. When a new electric vehicle enters the parking space, various types of information 1312 to 1317 are stored in association with the parking space ID 1311 of the parking space. When the electric vehicle is delivered, various information items 1312 to 1317 are deleted.

The parking space ID 1311 includes a user ID 1312 that is identification information of the user of the electric vehicle that has been stored, a storage time 1313 of the electric vehicle, a scheduled discharge time 1314 of the electric vehicle, and a user of the battery of the electric vehicle.

The identification information of the stored electric vehicle may be associated.

In the parking lot history information DB 132, the usage history of the parking lot 354 is stored. The parking lot history information DB 132 is realized by a table as shown in FIG. 4, for example.

In the parking lot history information DB 132, for each electric vehicle that has been issued, the date 1321 that has been issued, the user ID 1322 that is the identification information of the user of the electric vehicle, the entry time 1323 of the electric vehicle, Stored is history information in which the scheduled delivery time 1324 and the delivery time 1325 when the electric vehicle is delivered are associated with each other.

The charging plan information DB 133 stores a charging plan for an electric vehicle that has entered the parking lot 354. The charging plan information DB 133 is realized by a table as shown in FIG. 5, for example.

The charging plan information DB 133 stores a charging schedule 1332 for each parking space ID 1331. The charging schedule 1332 includes an entry time 1333 of the electric vehicle that has entered the parking space, a scheduled charge end time 1334 that is a predicted time when the charge amount of the battery of the electric vehicle reaches the specified charge amount or the maximum charge amount, and a planned release date. Time 1335 is included. Moreover, the information which matched the charging time zone information 1336 specified by the start time and the end time, and the change prohibition information 1337 which shows whether the said charging time zone is permitted or prohibited is contained. The charging time zone information 1336 specifies the charging time zone assigned to the electric vehicle stored in the parking space, and is arranged in time order, for example.

Using such a charging plan information DB 133, as shown in the figure, it is possible to generate a parking lot charging schedule indicating which parking space charging terminal 353 should be selected in which time zone.

Of course, the configuration of each DB is not limited to the structure described above.

The control unit 100 performs processing related to the charging plan. For example, the control unit 100 causes the arithmetic device 500 (see FIG. 2) to read and execute a predetermined program stored in the auxiliary storage device 530 (see FIG. 2) to the main storage device 510 (see FIG. 2). Realized.

The control unit 100 includes a parking lot usage status monitoring unit 101, a parking lot usage information generation unit 102, a parking lot history information generation unit 103, a charging plan generation unit 104, and a charging plan execution unit 105.

The parking lot usage monitoring unit 101 monitors changes in parking usage. In this embodiment, the parking lot utilization status monitoring unit 101 (1) whether or not an electric vehicle has been stored or discharged, (2) whether or not the current location of the user terminal 20 has passed a predetermined point, (3) It is monitored whether or not a request for changing the scheduled delivery time has been received from the user terminal 20. Specific description will be given in the order of (1) to (3).

(1) The parking lot utilization state monitoring unit 101 determines whether the warehousing information indicating that the warehousing has been received or the warehousing information indicating that the warehousing has been received from the charging facility management server 30. To monitor through.

The warehousing information includes, for example, a parking space ID of a parking space in which the electric vehicle has entered, a user ID of the electric vehicle, a warehousing time, a scheduled evacuation time, and a charging state. When the user inputs, the designated charge amount may be included. Vehicle identification information may be included.

The delivery information includes, for example, a parking space ID of a parking space from which an electric vehicle has been delivered, a user ID of the electric vehicle, and a delivery time. Vehicle identification information may be included.

(2) The parking lot usage status monitoring unit 101 monitors whether or not information including the current location information of the user terminal 20 has been received from the user terminal 20 via the communication unit 120. The received information includes user identification information of the user terminal 20 and parking space identification information. When the current location information is received, it is determined whether or not the current location information has reached a first predetermined point set in advance. When the first predetermined point is reached, the travel time is calculated using the position information of the first predetermined point and the preset position information of the second predetermined point.

The first predetermined point is a point set by the user, for example, the position of the nearest station of the user's commuting destination. For example, the first predetermined point may be input in advance to the user terminal 20 or the charging facility management server 30 by the user and transmitted to the charging plan management server 10 together with the user ID. The second predetermined point is a predetermined point, for example, the position of the nearest station of the parking lot 354 or the position of the parking lot 354. Note that the first predetermined point is, for example, that the location of the user's commute destination building is set, and instead of determining whether or not the first predetermined point has been reached, the current location of the user terminal 20 is the first It may be determined whether or not a certain distance away from one predetermined point.

The parking lot usage status monitoring unit 101 calculates such a travel time between two points using existing information using map information and route information. For example, the map information and route information may be stored in the storage unit 130 or may be acquired from an external server or the like via the network 40. Further, the travel time may be calculated by an external server or the like. The parking lot utilization status monitoring unit 101 predicts the scheduled delivery time by adding the calculated travel time to the time when the user terminal 20 reaches the first predetermined point.

Note that the user terminal 20 may periodically transmit the current location information, or may transmit the current location information when a user operation is performed. In addition, every time the parking lot usage status monitoring unit 101 receives the current location information from the user terminal 20 instead of determining arrival at the first predetermined location, the travel time from the current location to the second predetermined location May be calculated to predict the scheduled delivery time.

Further, instead of transmitting the current location information, the user terminal 20 may transmit a signal indicating that the user terminal 20 is heading to the parking lot. In this case, when the parking lot utilization status monitoring unit 101 receives a signal indicating that the parking lot is going to the parking lot, the parking lot utilization state monitoring unit 101 may predict the scheduled departure time based on a predetermined travel time, or the current location information of the user terminal 20 May be acquired from the user terminal 20 or a device such as a base station with which the user terminal 20 communicates, and the travel time to the current location and the second predetermined point may be predicted.

In addition, the user terminal 20 is equipped with a schedule management function, and by using the user's schedule information accumulated internally by the function, the user can enter the parking lot at the time when all the schedules for the day are completed. The user terminal 20 may automatically transmit information indicating that it is heading. In addition, location information is given to the schedule, and information indicating that the user goes to the parking lot at the time when the schedule having location information near the first predetermined point set in advance is completed. The user terminal 20 may transmit automatically.

In addition, when the parking lot utilization status monitoring unit 101 determines that the received current location information has reached the first predetermined point set in advance, the user checks whether the user is actually going to the parking lot. Confirmation request information may be transmitted to the terminal 20. The user terminal 20 that has received the confirmation request information displays the information on the display unit 220 and receives the confirmation result from the user via the input unit 210. Then, the user terminal 20 transmits the confirmation result to the parking lot usage status monitoring unit 101. When it is confirmed that the user is heading for the parking lot, the parking lot usage status monitoring unit 101 executes processing after determining that the user has reached the first predetermined point, and the user is not a parking lot. If it can be confirmed that the user is heading to the point, the processing is interrupted.

In addition, the parking lot utilization status monitoring unit 101 inputs information indicating that the scheduled delivery time is approaching or has passed with respect to the receipt information whose scheduled delivery time is within a certain time from the current time. You may transmit to the user terminal 20 of the user who did. The use terminal 20 that has received the information displays the information on the display unit 220.

Further, the parking lot usage status monitoring unit 101 may acquire information indicating that the user goes to the parking lot from another device instead of the user terminal 20. For example, a train ticket gate or a server device that monitors the ticket gate determines whether or not the user has passed the ticket gate, and transmits a signal indicating passage including the user identification information to the charging plan management server 10. . In this case, the ticket gate of the train or the server device that monitors the ticket gate has user identification information managed by the charging plan management server 10 and user identification information such as an IC card used when passing through the ticket gate. Should be managed in association with each other. The parking lot usage status monitoring unit 101 may calculate the travel time from the position of the ticket gate that the user has passed to the second predetermined point. Note that the IC card is integrated with the user terminal 20, and the user terminal 20 determines the passage of the user's ticket gate instead of the server device. A signal indicating passage including the identification information may be transmitted to the charging plan management server 10.

(3) The parking lot usage status monitoring unit 101 monitors whether or not a request for changing the scheduled delivery time has been received from the user terminal 20 via the communication unit 120.

In the present embodiment, it is assumed that the request for changing the scheduled delivery time is an advance request for changing the scheduled delivery time set by the user to an earlier scheduled delivery time, that is, advancing the scheduled delivery time. The advance request for the scheduled delivery time includes, for example, the parking space ID of the parking space in which the electric vehicle has entered, the user identification information of the electric vehicle, the scheduled delivery time after the change, and the designated charge amount. The designated charge amount may not be included.

The parking lot usage information generation unit 102 generates usage information stored in the parking lot usage information DB 131.

Specifically, the parking lot use information generation unit 102 acquires the receipt information when the parking lot use state monitoring unit 101 receives the receipt information. Then, the parking space ID 1311 corresponding to the parking space ID included in the warehousing information is associated with the user ID included in the warehousing information, the warehousing time, the scheduled evacuation time, and the charging state in the parking lot usage information DB 131. Store. When the designated charge amount is included in the warehousing information, the information is also stored.

Further, the parking lot usage information generation unit 102 calculates score information of the generated usage information and stores it as a score 1317. An example of the score information calculation method will be described with reference to FIG.

The parking lot usage information generation unit 102 calculates the difference between the entry time and the scheduled departure time of the generated usage information as the expected parking time. Also, a weight value corresponding to the scheduled parking time is calculated using a preset weight table (A). In the example of this figure, the weight table (A) includes a weight value m (m ₁ , m for each range of scheduled parking time (0 to 1 hour, 1 to 2 hours, 2 to 3 hours,...). ₂ , m ₃ ,...). The weight is set to increase as the scheduled parking time is shorter.

In addition, the parking lot use information generation unit 102 uses the history information stored in the parking lot history information DB 132 to calculate a value indicating a tendency that the leaving time is earlier than the expected leaving time.

For example, the parking lot usage information generation unit 102 specifies history information having a user ID 1322 corresponding to the user ID included in the generated usage information from the parking lot history information DB 132. Then, among the specified history information, history information having an earlier delivery time 1325 than the scheduled delivery time 1324 is identified. Then, the difference between the scheduled delivery time 1324 and the delivery time 1325 is calculated for each specified history information, and the average value of the difference values is calculated. This average value is used as a trend value indicating a tendency that the shipping time is earlier than the scheduled shipping time.

Then, the parking lot use information generation unit 102 calculates a weight value corresponding to the tendency value using a preset weight table (B). In the example of this figure, the weight table (B) includes a weight value n (n ₁ , n ₂ ) for each delivery time range (1-2 hours, 2-3 hours, 3-4 hours,...). , N ₃ ,...). The weight is set so as to increase as the tendency value increases.

When a plurality of weight values are calculated as described above, the parking lot usage information generation unit 102 calculates a score according to a predetermined formula. The predetermined formula is, for example, score W = m * n, and the score is calculated by the product of a plurality of weight values. In this way, the parking lot usage information generation unit 102 calculates the score of the user who has entered the store, and stores it as the score 1317 of the user.

Of course, the weight used for the above score calculation is an example, and is not limited to the above weight type. The weight calculation method is not limited to the method using a table. Further, the predetermined formula for calculating the score is not limited to the above, and the score may be obtained by summing the weights, for example.

When the parking lot usage information generation unit 102 receives the shipping information from the parking lot usage status monitoring unit 101, the parking lot usage information generation unit 102 acquires the shipping information. Then, the usage information 1312 to 1317 of the parking space ID 1311 corresponding to the parking space ID included in the exit information is deleted.

The parking lot usage information generation unit 102 predicts the scheduled delivery time by the parking lot usage status monitoring unit 101, and when the planned delivery time is changed, the scheduled delivery time of the usage information of the parking space in which the planned delivery time is changed. 1314 is updated with the scheduled shipping time after the change. Further, the weight value calculation based on the scheduled parking time, the weight value calculation based on the tendency of the shipping time, and the score are calculated, and the score 1317 of the usage information of the parking space whose scheduled shipping time is changed is updated.

When the parking lot utilization information generation unit 102 receives the advance request for the scheduled delivery time, the parking lot usage information generation unit 102 acquires the advance request. Then, the scheduled delivery time 1314 and the designated charge amount 1315 of the usage information of the parking space for which the advance request has been requested are updated with the scheduled delivery time and the designated charge amount included in the advance request. Further, the setting of the score information 1317 is changed based on the scheduled delivery time and the designated charge amount.

In the score setting change, the parking lot usage information generation unit 102 determines whether or not charging of the designated charge amount is completed by the scheduled delivery time. Specifically, for example, a charge state 1316 (for example, a value indicating the charge amount X%) of the usage information of the parking space for which the advance request has been made is acquired, and the specified charge amount is reached from the charge amount by the existing technology. To calculate the required charging time. Then, the required charging time calculated for the current time is added to calculate the scheduled charging end time, and it is determined whether the scheduled charging end time is before or after the scheduled shipping time.

When it is determined that the charging of the designated charging amount is completed by the scheduled departure time, the parking lot usage information generation unit 102 is “highest priority”, which means that the charging by the charging device 350 is dedicated until the scheduled charging end time, and Information indicating “change prohibited”, which means prohibiting the change of the dedicated charging time zone, is set as the score information 1317.

When it is determined that charging of the designated charge amount is not completed by the scheduled departure time, the parking lot use information generation unit 102 is “highest priority”, which means that the charging by the charging device 350 is dedicated until the scheduled departure time, and Information indicating “change permission” meaning that permission to change the dedicated charging time zone is set as the score information 1317.

It should be noted that the charging schedule of the “top priority” and “permitted to change” users is changed by changing the entry / exit of other users and the scheduled delivery time. Therefore, when adding, changing, or deleting the usage information, the parking lot usage information generation unit 102 uses the usage information in which “highest priority” and “change permission” are set in the score information 1317 other than the usage information. Identify. Then, the score information 1317 is updated by recalculating the score based on the scheduled parking time and history for the specified usage information.

The parking lot usage information generation unit 102 periodically updates the state of charge of the stored electric vehicle. The parking lot use information generation unit 102 periodically receives information including the parking space ID of the parking space in which the electric vehicle is stored, the user ID of the electric vehicle, and the charging state from the charging facility management server 30. Receive and update the corresponding charge state 1316. Further, the parking lot use information generation unit 102 sets information indicating “charge end” in the charge state 1316 when the charge state of the electric vehicle reaches the designated charge amount or the maximum charge amount of the electric vehicle.

In addition, the parking lot utilization status monitoring unit 101 stores a DB that stores a warehousing time and a eviction time that are a user's past parking garage usage history in the storage unit 130, and a planned garage time that is transmitted from the user terminal 20. The user's score may be calculated by comparing with the scheduled delivery time included in the change request. For example, for a user whose past delivery time is distributed in a predetermined range centering around 21:00, when a change request with a scheduled delivery time set to 18:00 is received from the user's usage terminal 20, the scheduled delivery It is determined that the credibility of the information that the time is 18:00 is low (determined that it is out of a predetermined range centering on 21:00), and the time distribution of the charging time described later is reduced by setting the score low. Possible methods.

The parking lot history information generation unit 103 generates history information stored in the parking lot history information DB 132 and the like.

When the parking lot usage information monitoring unit 101 receives the exit information, the parking lot history information generation unit 103 acquires the exit information. And the warehousing time 1323 and the warehousing time 1324 are acquired from the utilization information corresponding to the parking space ID contained in the warehousing information. Then, the current date, the user ID included in the exit information, the acquired entry time, the acquired exit scheduled time, and the exit time 1325 included in the exit information are associated with each other as history information. It adds to parking lot history information DB132.

The charging plan generation unit 104 generates a charging plan for a parking lot.

The charging plan generation unit 104 monitors whether there is a change in the parking lot usage information, and updates the charging plan if there is a change. When there is a change in the parking lot usage information, the parking lot usage status monitoring unit 101 detects a change in the parking lot usage status (above (1) to (3)) to add the parking lot usage information. This is when there is an update or deletion.

In the present embodiment, the charging device 350 can charge only one of the electric vehicles at the same time. Therefore, the charging plan generation unit 104 basically generates a charging schedule by round robin so that charging is performed in order for the electric vehicle that has been received. At that time, the charging time allocated to each electric vehicle is changed based on the score calculated based on the scheduled parking time and history (weighted round robin).

With reference to FIGS. 7 to 12, an example of a method for generating a charging plan in the present embodiment will be described.

For example, as shown in FIG. 7, the fixed time (reference time distribution) assigned to each user in round robin is “T”, and the scores of users A, B, C, and D are “Wa, Wb, Wc, Wd”. ”, The time distribution weighted by the users A, B, C, and D is expressed as“ Ta, Tb, Tc, Td ”, and Ta to Td are obtained by the following equations.
Ta = T * Wa / (Wa + Wb + Wc + Wd)
Tb = T * Wb / (Wa + Wb + Wc + Wd)
Tc = T * Wc / (Wa + Wb + Wc + Wd)
Td = T * Wd / (Wa + Wb + Wc + Wd)
In this way, the electric vehicle of the user with a higher score has a larger time distribution, so the amount of charge per predetermined time is greater than that of other users. That is, it is charged preferentially earlier than other users.

The charging plan generation unit 104 generates or updates the charging schedule as follows, for example, when there is a change in the parking lot usage information.

(1) Referring to the parking lot usage information DB 131, the usage information whose charging state 1316 does not indicate “end of charging” is specified. This is because usage information that has been charged is excluded from the charging schedule.

(2) Usage information that has been changed and usage information that is other than the changed usage information and whose score 1317 does not indicate "highest priority" and "change prohibited" is specified in (1) Identify from the information. This excludes the usage information other than the changed usage information, and the usage information whose score 1317 is “top priority” and “change prohibited” because the charging schedule has already been created and the charging schedule cannot be changed. Because.

(3) For each piece of usage information specified in (2), the time distribution is calculated using the above-described formula, and the time distribution calculated in the order from the earliest warehousing time is sequentially assigned as the charging time zone to generate a charging schedule. If a charging time zone of “top priority” and “change prohibited” has already been created, a charging schedule is generated after the charging time zone.

Here, for each usage information, the required charge time until the charge amount reaches the specified charge amount or the maximum charge amount is calculated, and the time when the allocated charge time zone reaches the required charge time is calculated as the scheduled charge end time To do. In the middle of assigning the charging time zone, if the scheduled charging end time is reached, the time allocation is calculated again for other usage information other than the usage information, and the charging time zone is assigned for the other usage information. Do.

In addition, when the score of the changed usage information is “top priority” and “change prohibited”, or “top priority” and “change permission”, the usage information continues until the scheduled charging end time or the scheduled delivery time. A charging time zone is assigned, and after the charging time zone, time allocation is calculated again for other usage information, and a charging time zone is assigned for the other usage information.

As described above, the charging plan generation unit 104 generates or updates a charging plan, and generates or updates a charging plan information DB as shown in FIG. The warehousing time 1333 is set with the warehousing time 1313 of the usage information, and the scheduled shipping time 1335 is set with the scheduled warehousing time 1314 of the usage information. The scheduled charging end time 1334 is set to the scheduled charging end time calculated in (3) above. The charging time zone 1336 is set with the charging time zone assigned in (3) above, and the change prohibition information 1337 is set to “prohibited” or “permitted” based on the score of the changed usage information. .

The description will be continued using more specific examples (FIGS. 8 to 12).

Referring back to FIG.

The charging plan execution unit 105 executes the charging plan generated by the charging plan generation unit 104.

For example, the charging plan execution unit 105 uses the current time and the charging schedule in the charging plan information DB 133 to identify the time for switching the parking space to be charged, and includes an instruction including the parking space ID of the switching destination parking space. The data is transmitted to the charging facility management server 30 via the communication unit 120.

Of course, if the charging target is switched, the control method is not limited to the above. For example, the charging plan execution unit 105 transmits information on the latest charging plan information DB 133 to the charging facility management server 30, and the charging facility management server 30 controls switching using the current time and the charging schedule in the charging plan information DB 133.

The input unit 310 is realized by, for example, the input device 540 (see FIG. 2). The display unit 320 displays an image or the like. The display unit 320 is realized by, for example, the display device 550 (see FIG. 2). The storage unit 340 stores various information used for processing by the control unit 330. The storage unit 340 is realized by, for example, the auxiliary storage device 530 (see FIG. 2).

The control unit 330 performs a process of controlling the other units and controlling the charging facility management server 30. For example, the control unit 330 reads and executes a predetermined program stored in the auxiliary storage device 530 (see FIG. 2) in the main storage device 510 (see FIG. 2) by the arithmetic device 500 (see FIG. 2). Realized.

The controller 330 receives, for example, the parking space identification information, the warehousing time, the vehicle identification information, and the charging state from the charging terminal 353 via the communication unit 300 and stores them in the storage unit 340. In addition, the user identification information for identifying the user and the scheduled delivery time of the electric vehicle 355 are received and stored in the storage unit 340 with respect to the parking space that has been received via the input unit 310. A specified charge amount may be accepted. The control unit 330 transmits the received information as warehousing information to the charging plan management server 10 via the communication unit 300.

Also, the control unit 330 receives the parking space identification information, the departure time, and the vehicle identification information from the charging terminal 353 via the communication unit 300 and stores them in the storage unit 340, for example. The control unit 330 transmits the information received in this way as delivery information to the charging plan management server 10 via the communication unit 300.

Further, the control unit 330 receives an instruction including the parking space ID of the switching destination parking space from the charging plan management server 10 via the communication unit 300, for example. And based on the said instruction | indication, the changeover switch 351 is controlled via the communication apparatus 352, and the supply destination of electric power is switched.

In addition, the control unit 330 periodically receives, for example, the charging state of the stored electric vehicle from each charging terminal 353 via the communication device 352.

Next, processing realized by the above-described charging plan management server 10 will be described.

FIG. 13 is a flowchart showing an example of a parking lot use state monitoring process. This flow is started after the charging plan management server 10 is activated.

In S10, the parking lot utilization status monitoring unit 101 determines whether or not there is a parking lot entry or a parking lot exit. Specifically, the parking lot utilization status monitoring unit 101 determines whether or not the warehousing information or the warehousing information is received from the charging facility management server 30. When the warehousing information is received (S10: warehousing), the process proceeds to S20. When the delivery information is received (S10: delivery), the process proceeds to S60. If any information has not been received (S10: NO), the process proceeds to S80.

In S20, the parking lot use information generation unit 102 sets a larger weight as the scheduled parking time is shorter. Specifically, the parking lot use information generation unit 102 calculates the difference between the warehousing time and the scheduled evacuation time included in the warehousing information received in S10 as the scheduled parking time, and uses a preset weight table (A). The weight value corresponding to the scheduled parking time is calculated. Then, the process proceeds to S30.

In S30, the parking lot usage information generation unit 102 sets the weight to be larger as the tendency to get out is faster. Specifically, the parking lot usage information generation unit 102 specifies history information having a user ID 1322 corresponding to the user ID included in the warehousing information received in S10 from the parking lot history information DB 132. Then, among the specified history information, history information having an earlier delivery time 1325 than the scheduled delivery time 1324 is identified. Then, the difference between the scheduled delivery time 1324 and the delivery time 1325 is calculated for each specified history information, and an average value (trend value) of each difference value is calculated. Then, the parking lot use information generation unit 102 calculates a weight value corresponding to the tendency value using a preset weight table (B). Then, the process proceeds to S40.

In S40, the parking lot use information generation unit 102 calculates a score. Specifically, the parking lot usage information generation unit 102 calculates the score of the user who has entered the store using the weight value calculated in S20 and S30 and a predetermined formula. Then, the process proceeds to S50.

In S50, the parking lot usage information generation unit 102 adds parking lot usage information. Specifically, the parking lot use information generation unit 102 adds the user ID included in the warehousing information, the warehousing time, and the delivery to the parking space ID 1311 corresponding to the parking space ID included in the warehousing information received in S10. The scheduled time, the state of charge, and the score calculated in S40 are stored in association with each other. Then, the process returns to S10.

In S <b> 50, the parking lot usage information generation unit 102 specifies usage information in which “highest priority” and “change permission” are set in the score information 1317 other than the usage information to be added. Then, the score information 1317 is updated by recalculating the score based on the scheduled parking time and history for the specified usage information.

In S60, the parking lot history information generation unit 103 adds parking lot history information. Specifically, the parking lot history information generation unit 103 acquires the entry time 1323 and the expected delivery time 1324 from the usage information corresponding to the parking space ID included in the delivery information received in S10. Then, the current date, the user ID included in the exit information, the acquired entry time, the acquired exit scheduled time, and the exit time 1325 included in the exit information are associated and added as history information. To do. Then, the process proceeds to S70.

In S70, the parking lot usage information generation unit 102 deletes the parking lot usage information. Specifically, the parking lot usage information generation unit 102 deletes the usage information 1312 to 1317 of the parking space ID 1311 corresponding to the parking space ID included in the exit information received in S10. Then, the process returns to S10.

In S <b> 70, the parking lot usage information generation unit 102 specifies usage information in which “highest priority” and “change permission” are set in the score information 1317 other than the usage information to be deleted. Then, the score information 1317 is updated by recalculating the score based on the scheduled parking time and history for the specified usage information.

In S80, the parking lot usage status monitoring unit 101 determines whether or not the user has reached a predetermined point. Specifically, the parking lot usage status monitoring unit 101 monitors whether or not information including the current location information of the user terminal 20 has been received from the user terminal 20 via the communication unit 120. When the current location information is received, it is determined whether or not the current location information has reached a first predetermined point (for example, the nearest station of work) set in advance. If the user has reached the first predetermined point (S80: YES), the process proceeds to S90. If the user has not reached the first predetermined point and if the current location information has not been received (S80: NO), the process proceeds to S140.

In S90, the parking lot utilization status monitoring unit 101 predicts the scheduled delivery time. Specifically, the parking lot usage status monitoring unit 101 uses the map information and the route information to detect the position information of the first predetermined point and the second predetermined point set in advance (for example, the most recent parking lot. The travel time with the location information of the station is calculated. In addition, the estimated delivery time is predicted by adding the calculated travel time to the time when the user terminal 20 reaches the first predetermined point. Then, the process proceeds to S100.

In S100, the parking lot use information generation unit 102 sets a larger weight as the scheduled parking time is shorter. Specifically, the parking lot usage information generation unit 102 specifies the parking space ID or the usage information of the user ID included in the information received from the user terminal 20 in S80 from the parking lot usage information DB 131. Then, the difference between the warehousing time 1313 included in the use information and the scheduled warehousing time calculated in S90 is calculated as the scheduled parking time, and the pre-set weight table (A) is used to correspond to the planned parking time. A weight value is calculated. Then, the process proceeds to S110.

In S110, the parking lot usage information generation unit 102 sets the weight to be larger as the tendency of the departure to be faster. This process is basically the same as S30. However, the parking lot usage information generation unit 102 specifies history information having a user ID 1322 corresponding to the user ID included in the information received from the user terminal 20 in S80 from the parking lot history information DB 132. Then, the process proceeds to S120. Note that this process may not be executed.

In S120, the parking lot usage information generation unit 102 calculates a score. Specifically, the parking lot use information generation unit 102 calculates the score of the user who has reached a predetermined point using the weight value calculated in S100 and S110 and a predetermined formula. Then, the process proceeds to S130.

In S130, the parking lot usage information generation unit 102 updates the parking lot usage information. Specifically, the parking lot usage information generation unit 102 uses the parking space ID or the user ID usage information included in the information received from the user terminal 20 in S80, and the scheduled delivery time calculated in S90, and S120. Update with the score calculated in. Then, the process returns to S10.

In S <b> 130, the parking lot usage information generation unit 102 identifies usage information in which “highest priority” and “change permission” are set in the score information 1317 other than the usage information to be updated. Then, the score information 1317 is updated by recalculating the score based on the scheduled parking time and history for the specified usage information.

In S140, the parking lot utilization situation monitoring unit 101 determines whether or not a request for advance of the scheduled time for delivery has been received. Specifically, the parking lot utilization status monitoring unit 101 determines whether or not a request for advance of the scheduled delivery time has been received from the user terminal 20. When the advance request for the scheduled delivery time is received (S140: YES), the process proceeds to S150. If not received (S140: NO), the process returns to S10.

In S150, the parking lot usage information generation unit 102 determines whether or not the designated charge amount can be charged by the scheduled delivery time. Specifically, the parking lot usage information generation unit 102 specifies the usage information of the parking space ID included in the advance request received in S140 from the parking lot usage information DB 131. Then, the required charging time is calculated using the charging state 1316 included in the usage information and the designated charging amount included in the advance request. Then, the required charging time calculated for the current time is added to calculate the scheduled charging end time, and it is determined whether the scheduled charging end time is before or after the scheduled shipping time included in the advance request.

When the scheduled charging end time is before the scheduled shipping time (S150: YES), the parking lot usage information generating unit 102 advances the process to S160.

When the scheduled charging end time is earlier than the scheduled delivery time, the parking lot usage information generation unit 102 sets the charging plan of the user to “highest priority” to the user terminal 20 that has transmitted the advance request for the scheduled delivery time. Inquiry about whether or not to set to “change prohibited” may be transmitted. The user terminal 20 receives the inquiry, displays the content on the display unit 220, accepts the user's instruction via the input unit 210, and transmits it to the charging plan management server 10. When the parking lot usage information generation unit 10 receives an instruction to permit setting from the user terminal 20, the parking lot usage information generation unit 10 proceeds with the process to S160. If an instruction not permitting setting is received from the user terminal 20, the process may proceed to S180. Such inquiries are made by, for example, determining whether to allow the generation of a charge when assuming a mechanism that generates a charge in order to set the charging plan to the highest priority and prohibition of change. This is to make it happen.

If the scheduled charging end time is after the scheduled shipping time (S150: NO), the parking lot usage information generating unit 102 advances the process to S180.

If the specified charge amount is not included in the advance request, NO may be determined in S150.

In S160, the parking lot use information generation unit 102 sets the charge plan of the user who has requested the advance of the scheduled delivery time as the highest priority and the change prohibition. Specifically, the parking lot use information generation unit 102 sets the score of the user who requested the advance received in S140 as information indicating “top priority” and “change prohibited”. Then, the process proceeds to S170.

In S170, the parking lot usage information generation unit 102 updates the parking lot usage information. Specifically, the parking lot usage information generation unit 102 uses the parking space ID or the user ID usage information included in the advance request received from the user terminal 20 in S140, and the scheduled delivery time included in the advance request. Update with the specified charge amount and the score set in S160. Then, the process returns to S10.

In S <b> 170, the parking lot usage information generation unit 102 specifies usage information in which “highest priority” and “change permission” are set in the score information 1317 other than the usage information to be updated. Then, the score information 1317 is updated by recalculating the score based on the scheduled parking time and history for the specified usage information.

In S180, the parking lot use information generation unit 102 sets the charge plan of the user who has requested the advance of the scheduled delivery time to the highest priority and change permission. Specifically, the parking lot utilization information generation unit 102 sets the score of the user who requested the advance received in S140 as information indicating “highest priority” and “permitted to change”. Then, the process proceeds to S190.

In S190, the parking lot usage information generation unit 102 updates the parking lot usage information. Specifically, the parking lot usage information generation unit 102 uses the parking space ID or the user ID usage information included in the advance request received from the user terminal 20 in S140, and the scheduled delivery time included in the advance request. Update with the specified charge amount and the score set in S180. Then, the process returns to S10.

In S <b> 190, the parking lot usage information generation unit 102 specifies usage information in which “highest priority” and “change permission” are set in the score information 1317 other than the usage information to be updated. Then, the score information 1317 is updated by recalculating the score based on the scheduled parking time and history for the specified usage information.

FIG. 14 is a flowchart showing an example of the charging plan update process. This flow is started after the charging plan management server 10 is activated.

In S200, the charging plan generation unit 104 determines whether there is a change in the parking lot usage information. Specifically, the charging plan production | generation part 104 determines whether there was any change in parking lot utilization information by S50 of FIG. 13, S70, S130, S170, and S190. If there is a change in the parking lot usage information (S200: YES), the process proceeds to S210. If there is no change in the parking lot usage information (S200: NO), the determination is continued.

In S210, the charging plan generation unit 104 updates the charging plan by round robin based on the score of each user. The specific processing contents are as described with reference to FIGS. The charge plan production | generation part 104 updates a charge plan, and returns a process to S200.

Each of the processing units in FIGS. 13 to 14 is divided according to the main processing contents in order to make the processing of the charging plan management server 10 easy to understand. The present invention is not limited by the way of dividing the processing unit or the name. The processing of the charging plan management server 10 can be divided into more processing units according to the processing contents. Moreover, it can also divide | segment so that one process unit may contain many processes.

FIG. 15 is a diagram illustrating an example of a confirmation screen displayed on the user terminal 20. The confirmation screen is confirmation information for confirming whether or not the user really goes to the parking lot when the parking lot usage situation monitoring unit 101 determines in S80 whether or not the user has reached the predetermined point. Is transmitted to the user terminal 20, it is displayed on the display unit 330. This figure assumes a touch panel in which the display unit 220 and the input unit 210 are integrated.

15, the display area 1500 displays a text indicating an intention to confirm whether or not to go to the parking lot transmitted from the parking lot usage monitoring unit 101. The return home button 1501 and the detour button 1502 are areas for allowing the user to input whether to go to the parking lot to go home or to go to the parking lot to take a detour. The user terminal 20 transmits the result of touching either button to the parking lot usage status monitoring unit 101. Further, the map 1503, the current position 1504, and the predetermined point 1505 are used as reference information for the user. The current position of the user terminal 20 when confirming whether or not to go to the parking lot and the registered predetermined position are , Displayed together with the map. Information regarding the map 1503 may be stored in the storage unit 240 of the user terminal 20 or stored in the storage unit 130 of the charging management server 10 and when confirmation information is transmitted to the user terminal 20. Then, map information relating to the vicinity of the current location may be transmitted and output to the display unit 330.

Heretofore, an example of an embodiment of the present invention has been described. According to this embodiment, the charge plan according to the fluctuation | variation of the length of parking time and the length of parking time can be produced | generated.

For example, in this embodiment, a charging schedule is generated according to the length of each user's scheduled parking time. According to such a configuration, charging is performed more preferentially for a user whose time from the entry time to the scheduled delivery time is shorter, so that the user's satisfaction with charging can be improved.

Also, for example, in the present embodiment, a charging schedule is generated according to a tendency that each user gets out faster. According to such a configuration, charging is performed more preferentially for a user who has a greater tendency for the actual shipping time to be earlier than the scheduled shipping time, so that the user's satisfaction with charging can be improved.

Also, for example, in this embodiment, the scheduled delivery time is predicted based on the user's location information, and the charging schedule is updated based on the predicted scheduled delivery time. According to such a configuration, the charging schedule is generated based on the scheduled delivery time that is predicted to be as close as possible to the actual delivery time, so that the user's satisfaction with charging can be improved.

Also, for example, in the present embodiment, the charging schedule is updated based on the scheduled delivery time that is forwarded in response to a user request. According to such a configuration, the charging schedule is generated based on the scheduled delivery time that is predicted to be as close as possible to the actual delivery time, so that the user's satisfaction with charging can be improved. Moreover, since the charging time slot | zone can be occupied when the scheduled delivery time is put forward, a user's satisfaction with charge can be improved.

It should be noted that the above-described exemplary embodiment of the present invention is intended to illustrate the gist and scope of the present invention and is not intended to be limiting. Many alternatives, modifications, and variations will be apparent to those skilled in the art.

For example, the user terminal 20 may transmit a change request (extension request) for extending the scheduled delivery time in addition to an advance request for the scheduled delivery time. In this case, the parking lot utilization status monitoring unit 101 receives the extension request. The parking lot usage information generation unit 102 may calculate the weight and the score based on the extended scheduled departure time and update the parking lot usage information. In this way, the charging time is allocated to users other than the extended user.

Also, for example, the user may be able to set the specified charge amount at the time of warehousing. In this case, when the parking lot use information generation unit 102 receives the warehousing information, the score is “highest priority” and “change prohibited” depending on whether or not the designated charging amount can be charged by the scheduled time of leaving. Alternatively, “highest priority” and “change permission” may be set.

In the above embodiment, the charging time zones are assigned in the order of receipt in round robin, but the order is not limited to the order of receipt. For example, you may allocate in order of a parking space from the parking space where utilization information was changed.

Also, for example, when there is a request to advance the scheduled delivery time, the score may be increased to a predetermined value instead of exclusively using the user for charging. Specifically, for example, the score calculation formula is score W = m * n * p. p is set to “p = 1” when it is not “highest priority”, and is set to a predetermined value greater than 1 when it is “highest priority”. When there is a request to advance the scheduled delivery time, the parking lot usage information generation unit 102 obtains m based on the revised scheduled delivery time, obtains n based on the history, and further sets p to the predetermined value. And the score W is calculated. The parking lot utilization information generation unit 102 calculates the score W by setting p to 1 when the score is updated due to the prediction of the entry or departure scheduled time. In this way, the highest priority user can be preferentially charged. In addition, when “highest priority” is set, “change prohibited” or “change allowed” may be set in the score depending on whether or not the specified charge amount can be charged by the scheduled delivery time. .

In addition, for example, as history information, information indicating that the scheduled delivery time is the time set by the advance request is stored, and there is a history in which the outgoing time is later than the scheduled delivery time set by the advance request In addition, the user's score may be reduced according to the average value of the delayed time and the number of times of delay.

Also, for example, for users who tend to have the delivery time later than the scheduled delivery time, the weight may be reduced.

Also, for example, the number of forward requests may be stored for each user as history information, and the score of the user may be increased according to the number of times.

In the above embodiment, the charging plan management server 10 generates a charging plan, but the present invention is not limited to this form. For example, at least a part of the functions of the charging plan management server 10 may be included in the charging facility management server 30.

The present invention is not limited to the above-described exemplary embodiment, and includes various modifications. For example, the above-described exemplary embodiment has been described in detail for the purpose of explaining the present invention in an easy-to-understand manner, and is not limited to one having all the configurations described. A part of the configuration of an example of an embodiment can be replaced with the configuration of another example. Moreover, it is also possible to add the structure of another example to the structure of an example of a certain embodiment. In addition, for a part of the configuration of an example of each embodiment, another configuration can be added, deleted, or replaced. In addition, each of the above-described configurations, functions, processing units, processing means, and the like are realized by hardware by, for example, designing them with an integrated circuit, and the processor interprets and executes the program. It may be realized by software. In addition, the control lines and information lines in the figure indicate what is considered necessary for the description, and do not necessarily indicate all of them. It may be considered that almost all the components are connected to each other.

The present invention can be applied not only to an electric vehicle that uses battery power as a power source, but also to a mobile body that uses electricity from a capacitor as a power source, such as a mobile body that uses power from a supercapacitor as a power source. Furthermore, the present invention can be applied to a moving body that uses the energy of the energy storage device as a power source. It should be noted that the present invention is more effective when applied when it takes a relatively long time to store energy.
