Description

The present invention relates to a data management device, a test system, a data management program, and a data management method.

As shown in Patent Document 1, a conventional data management device is constructed to enable test traceability by collecting and managing, for example, the temperature of the soak chamber in which the test vehicle is stored and the temperature of the test vehicle.

On the other hand, in recent years, with the need for electrification in the automotive market, there has been an increase in testing of vehicles that use electricity as an energy source, such as EVs (electric vehicles) and PHVs (plug-in hybrid vehicles).

However, in previous tests of EVs and PHVs, it was common to visually check the measured battery charge and record it by hand, which could lead to human error and undermine the reliability of the data obtained.

Furthermore, although the test vehicle is temperature-controlled in the soak chamber mentioned above, the battery temperature rises during charging, and there is a possibility that the battery temperature may be significantly different from the set temperature of the soak chamber. If this happens, for example, when the test vehicle is moved from the soak chamber to the test room immediately after charging is completed, the temperature of the test vehicle, which should have been temperature-controlled, may not be maintained until the start of the test, and the reliability of the data may be compromised.

JP 2020-118671 A

Therefore, the main objective of the present invention is to prevent human error and improve the reliability of data by making it possible to automatically collect battery charge and temperature data during testing of EVs and PHVs.

In other words, the data management device according to the present invention is a data management device that manages the charging state of a vehicle or a part thereof that is a test specimen that has a battery, and is characterized by having a charging state acquisition unit that acquires charging data indicating the charging state of the test specimen that is being charged in a soak room in which the test specimen is stored or in a test room in which the test specimen is tested, a battery temperature acquisition unit that acquires battery temperature data indicating the temperature of the battery, and an output unit that associates the charging data and the battery temperature data and outputs them.

The data management device configured in this way correlates charging data with battery temperature data and outputs it, making it possible to automatically collect the battery charge and battery temperature, preventing human error caused by conventional handwritten records and improving the reliability of the data obtained.

It is preferable that the device further includes a soak end determination unit that determines that the soak in the soak chamber of the test specimen has ended when a predetermined condition is satisfied, and the predetermined condition includes at least one of the following: a difference or ratio between the temperature of the battery indicated by the battery temperature data and a set temperature of the soak chamber is within a predetermined range, an amount of change in the temperature of the battery indicated by the battery temperature data is within a predetermined range, or a predetermined time has elapsed since charging of the battery was completed. The predetermined condition may also be a combination of two or more of these.
This prevents the test specimen from being moved from the soak chamber to the test room when the battery temperature is significantly different from the set temperature of the soak chamber, and allows the temperature of the test specimen to be maintained at the controlled temperature until the start of the test.

It is preferable that the charging state acquisition unit acquires a power waveform indicating the behavior of the power supplied to the battery as the charging data, and the output unit outputs at least one of the power waveform or the charge amount of the battery obtained based on the power waveform in association with the battery temperature data.
In this case, the change over time in the power supplied to the battery or the charge level of the battery can be recorded in association with the battery temperature.

It is preferable that the battery further includes a charging completion determination unit that determines whether charging of the battery is complete based on the number of times or the time that a power waveform indicating the behavior of the power supplied to the battery falls below a predetermined reference value.
This makes it possible to automatically determine when the battery has finished charging, which is more likely to prevent human error and improves the reliability of the data than if an operator had to determine when charging was complete.

In order to automatically and accurately determine when the battery is fully charged, the test specimen is preferably further provided with a plug monitoring unit that determines whether or not a power plug is inserted, and the charging completion determination unit determines that charging of the battery is fully charged when the plug monitoring unit determines that the power plug is inserted into the test specimen and the power waveform falls below a predetermined reference value for a predetermined period of time.

It is preferable that the charging device further comprises an alarm unit which compares the power waveform with a predetermined threshold value to determine whether or not the charging state is normal, and which notifies the user when it is determined that the charging state is not normal.
This makes it possible to notify the operator of any abnormalities, such as if the power plug is not properly inserted into the test specimen.

When the charging method for the test specimen is switched to normal charging, rapid charging, or recharging, it is preferable that the notification unit switches the threshold value depending on the charging method.
In this case, the abnormality determination by the notification unit can be applied to a plurality of charging methods.

It is preferable that the device further includes an ambient temperature acquisition unit that acquires ambient temperature data indicating the ambient temperature of the test specimen from a temperature sensor installed in the soak chamber or the test chamber, and that the output unit outputs the charging data, the battery temperature data, and the ambient temperature data in association with each other.
This makes it possible to automatically collect and manage the temperatures of soak rooms and test rooms, making it possible to build a system with high traceability.

It is preferable that the vehicle further comprises a data management unit that stores the charging data output by the output unit and the travel distance of the test specimen in association with each other.
In this way, it is possible to manage the power consumption rate (electricity consumption) obtained based on the amount of power consumed and the distance traveled.

It is preferable that the battery further includes a battery remaining capacity acquisition unit that acquires remaining capacity data indicating the remaining capacity of the battery, and a charge completion prediction unit that predicts the required charging time required to complete charging of the battery or the charge completion time when charging will be completed based on the remaining capacity data.
This would allow prediction of the required charging time and the time when charging will be completed, which would be useful for scheduling tests, for example.

The present invention also provides a test system that includes the above-mentioned data management device, a dynamometer on which the test specimen is placed or connected, and a running test management device that transmits and receives data between the data management device and the dynamometer.

The data management program according to the present invention is a data management program for managing the charging state of a vehicle or a part thereof that is a test specimen having a battery, and is characterized in that it causes a computer to perform the functions of a charging state acquisition unit that acquires charging data indicating the charging state of the test specimen that is being charged in a soak room in which the test specimen is stored or in a test room in which the test specimen is tested, a battery temperature acquisition unit that acquires battery temperature data indicating the temperature of the battery, and an output unit that associates the charging data and the battery temperature data and outputs them.

Furthermore, the data management method according to the present invention is a data management method for managing the charging state of a vehicle or a part thereof that is a test specimen having a battery, and is characterized by comprising a charging state acquisition step for acquiring charging data indicating the charging state of the test specimen that is being charged in a soak room in which the test specimen is stored or in a test room in which the test specimen is tested, a battery temperature acquisition step for acquiring battery temperature data indicating the temperature of the battery, and an output step for outputting the charging data and the battery temperature data in association with each other.

Such a test system, data management program, and data management method can achieve the same effects as the data management device described above.

The present invention, configured in this way, makes it possible to automatically collect battery charge and temperature data when testing electric vehicles such as EVs and PHVs that use electricity as an energy source, thereby preventing human error and improving data reliability.

FIG. 11 is a functional block diagram showing functions of a data management device and a driving test management device according to another embodiment.

Below, one embodiment of the test system according to the present invention will be described with reference to the drawings.

The test system 100 of this embodiment tests a test specimen V, which is an electric vehicle such as an EV or PHV that uses electricity as an energy source, or a part of such an electric vehicle. In the following, the test specimen V will be described as a completed vehicle (hereinafter, simply referred to as vehicle V).

As shown in FIG. 1, this test system 100 includes a driving test device 1 that performs a driving test on a vehicle V under test, a charging system 2 that charges the battery mounted on the vehicle V, and a driving test management device 3 that transmits and receives various data related to the test between the driving test device 1 and the charging system 2.

As shown in FIG. 1, the running test device 1 is equipped with a dynamometer placed in a test room. In this case, the dynamometer is a chassis dynamometer equipped with rollers 11 on which the wheels of the vehicle V are placed and a motor (not shown) connected to the rollers 11.

The charging system 2 charges the battery before and after the test, and as shown in FIG. 1, includes one or more charging devices 21 that supply power to the battery of the vehicle V, one or more power meters 22 that measure the amount of power supplied to the battery by the charging devices 21, and a data management device 23 that manages the amount of power measured by the power meters 22.

The charging system 2 is provided in a vehicle storage room called a soak room, which is used to keep the vehicle V at a predetermined constant temperature (for example, around 25°C) depending on the type of driving test. This soak room is configured to be able to store multiple vehicles V simultaneously, and the vehicles V before and/or after the driving test are placed in this soak room and charged. The charging system 2 may also be provided in a test room.

The charging equipment 21 supplies AC or DC power to the battery under test, and includes a charging outlet 211 into which a power plug of a charging cable is inserted, one end of which is inserted into the charging port of the vehicle V, and a power source 212 connected to the charging outlet 211 via a power supply line.

Methods of charging the battery from the charging equipment 21 include normal charging, which supplies a predetermined normal power, rapid charging, which supplies a power higher than the normal power, and recharging, which stops the supply of power and then starts it again. The charging equipment 21 here is configured so that the user can appropriately set and change which of the above-mentioned charging methods is to be used, or how to switch between multiple methods.

The graph in Figure 3 shows an example of the power supplied to the battery from the charging equipment 21 and the change over time in the charge level of the battery. In this example, a charging method is used in which the battery is fully charged by normal charging, and more specifically, the battery is fully charged by supplying a constant power, for example.

The power meter 22 measures the power supplied from the charging equipment 21 to the battery of the vehicle V and is connected to the power supply line provided in the charging equipment 21.

The data management device 23 is a dedicated or general-purpose computer equipped with a CPU, internal memory, an input/output interface, an A/D converter, etc., and is a portable terminal device such as a tablet, smartphone, or laptop computer that can be carried between the soak chamber and the test room.

Based on a predetermined program stored in the internal memory, the data management device 23 performs at least the functions of a charging status acquisition unit 231, a battery temperature acquisition unit 232, and an output unit 233, as shown in Figure 2, by the CPU and peripheral devices working together.
These functions will now be described with reference to the flow chart of FIG.

The charging status acquisition unit 231 acquires charging data indicating the charging status of the vehicle V being charged in the soak room (S1). If the vehicle V is being charged in a test room, the charging status acquisition unit 231 acquires charging data indicating the power receiving status of the vehicle V being charged in this test room.

As shown in FIG. 2, the charge state acquisition unit 231 acquires, as charging data, various pieces of information related to the power measured by the power meter 22 during charging before and/or after the driving test.
Specifically, the charging data includes at least one of a power waveform indicating the behavior of the power supplied to the battery, a charging start time when charging of the battery began, a charging end time when charging of the battery ended, a charging time during which the battery is being charged, an instantaneous power value, an instantaneous current value, an instantaneous voltage value, an average value of the amount of power, current, and voltage, and a charge amount of the battery.

The following describes a case where the charging state acquisition unit 231 acquires a power waveform as charging data. In other words, this power waveform is the change over time in the power value of the power supplied to the battery, and the charging state acquisition unit 231 here also acquires the charge amount calculated based on this power waveform as charging data. Note that the charge amount can be calculated, for example, by integrating the power waveform over the charging time.

The battery temperature acquisition unit 232 acquires battery temperature data indicating the temperature of the battery, and acquires the battery temperature data at least during charging (S2).

In this embodiment, as shown in FIG. 2, the vehicle V is equipped with a temperature sensor TS that detects the temperature of the battery, and the temperature detected by this temperature sensor TS when the battery is being charged is acquired by the battery temperature acquisition unit as battery temperature data. Note that while FIG. 2 shows one temperature sensor TS provided on the battery, multiple temperature sensors TS may be provided on the battery, and the average value of the temperature sensors TS may be used as the battery temperature data. The temperature sensor TS may be provided directly on the battery or in the vicinity of the battery. Furthermore, the battery temperature acquisition unit 232 may acquire battery temperature data from the OBD.

The output unit 233 outputs the charging data and the battery temperature data in association with each other, and in this embodiment, outputs the charging data and the battery temperature data in association with each other to the driving test management device 3 described later (S3). However, the output unit 233 may be a unit that outputs and records the charging data and the battery temperature data in association with each other to a data storage unit such as a memory provided in the charging system 2 or an external memory such as the cloud, a USB memory, or an SD card.

Specifically, the output unit 233 links the charging data and the battery temperature data by time and outputs them. In other words, the output unit 23 links the charging data and the battery temperature data acquired by the battery temperature acquisition unit 232 at the time when the charging data was acquired by the charging state acquisition unit 231, and outputs them.

In this embodiment, as shown in FIG. 1, identification information is given to the test specimen in advance to identify the test specimen, the vehicle V, and the output unit 233 can output the identification information in association with the above-mentioned charging data and battery temperature data.

To explain more specifically, as shown in FIG. 2, the data management device 23 of this embodiment is configured to include an identification information acquisition unit 234 that acquires the above-mentioned identification information, and an output unit 233 that outputs the identification information acquired by the identification information acquisition unit 234.

In this embodiment, the identifier acquisition unit 234 is configured to acquire identification information by reading a symbol Sv, such as a two-dimensional code, that is provided in advance on the vehicle V, which is the test specimen, with an imaging means 235, such as a camera. Note that the identifier acquisition unit 234 may acquire identification information that is manually input, for example, or that is transmitted from an external source.

Furthermore, as shown in FIG. 2, the data management device 23 of this embodiment also has the functions of a charging completion determination unit 236, a soak end determination unit 237, and a plug monitoring unit 238. However, the data management device 23 does not necessarily need to have all of these functions.

The charging completion determination unit 236 determines whether or not charging of the battery is complete based on the number of times or the time that the power waveform falls below a predetermined reference value, and specifically, determines that charging of the battery is complete when at least a first condition determined based on the power waveform is satisfied.

To explain this first condition, for example, the first condition can be that the power waveform falls below the reference value at least once for a predetermined period of time. The reference value may be set to a value slightly higher than zero, as shown in Figure 3, or may be set to zero, although not shown.

The charging method is not limited to the method shown in FIG. 3. For example, as shown in FIG. 5, a charging method is also known in which the battery is nearly fully charged by normal charging, and then recharged multiple times to more reliably achieve full charging. In this case, the first condition may be, for example, that the number of times the power waveform falls below a reference value for a predetermined period of time exceeds a predetermined number.

In other words, the charging completion determination unit 236 of this embodiment is configured to acquire the charging data described above and determine whether or not the first condition is satisfied based on the power waveform contained in this charging data.

The soak end determination unit 237 determines that the soak of the test specimen vehicle V in the soak chamber has ended when certain conditions are met.

The predetermined condition includes, for example, that the time that the vehicle V has been stored in the soak chamber has exceeded a predetermined time (first time), and/or that the difference or ratio between the battery temperature indicated by the battery temperature data and the set temperature of the soak chamber is within a predetermined range (first range), and/or that the amount of change in the battery temperature indicated by the battery temperature data is within a predetermined range (second range), and/or that a predetermined time (second time) has elapsed since charging of the battery was completed, etc. In addition, when the vehicle V is a PHV, the predetermined condition can include that the difference or ratio between the oil temperature and/or water temperature of the vehicle V and a predetermined target temperature is within a predetermined range (third range).
The first, second, and third ranges may be different from each other or may be the same range, and the first and second times may be different from each other or may be the same time.

Here, the above-mentioned soak end determination unit 237 is configured to obtain the battery temperature indicated by the battery temperature data and the set temperature of the soak chamber, compare these temperatures, and determine whether the soak has ended based on at least the result of this comparison.

The soak end determination unit 237 may be configured to notify the operator that the soak has ended, for example, by sound, light, or screen display, when the above-mentioned predetermined conditions are met.

Here, we return to the description of the charging completion determination unit 236 described above.
As described above, this charging completion determination unit 236 may determine that battery charging is complete when the first condition is satisfied. However, here, it determines that battery charging is complete when both the above-mentioned first condition and a second condition determined by the plug monitoring unit 238 described later are satisfied.

To explain this second condition, in this embodiment, the plug monitoring unit 238 is configured to determine whether or not a power plug is inserted into the vehicle V under test, and the second condition is that the plug monitoring unit 238 has determined that a power plug is inserted into the vehicle V.

As a specific example of the plug monitoring unit 238, as shown in FIG. 2, it can be configured to determine whether a plug is inserted into the vehicle V based on whether a signal indicating that a plug is inserted is received from the OBD.

Another aspect of the plug monitoring unit 238 may be to acquire image data of the charging port of the vehicle V and determine whether a plug is inserted into the vehicle V based on the image data.

Then, when the plug monitoring unit 238 determines that the plug is inserted into the vehicle V, the charging completion determination unit 236 described above accepts the determination result and determines that the second condition is satisfied.

In this way, the charging completion determination unit 236 determines that charging of the battery of the vehicle V is completed when both the first condition and the second condition are satisfied.
In addition, the charging completion determination unit 236 may determine that charging of the battery of the vehicle V is complete when only the first condition is satisfied, without taking the second condition into consideration.

The charging completion determination unit 236 may be configured to notify the operator that charging of the battery of the vehicle V is complete, for example, by sound, light, or screen display, when the first and second conditions described above are satisfied.

Returning to FIG. 1, the driving test management device 3 collects and manages various information from the driving test device 1 and the charging system 2 described above, and is specifically a dedicated or general-purpose computer equipped with a CPU, memory, an input/output interface, an A/D converter, etc.

The driving test management device 3 performs at least the functions of a test device control unit 31 and a data storage unit 32, as shown in FIG. 2, by the CPU and peripheral devices working together based on the program stored in the memory.

The test device control unit 31 controls the dynamometer 1 and performs a running test on the vehicle V placed on the dynamometer 1 in a predetermined running mode. The test device control unit 31 outputs running distance data indicating the running distance of the vehicle V in the running test to the data storage unit 32. The running distance indicated by the running distance data is calculated, for example, from the number of rotations of the rollers 11 of the dynamometer 1, and is the total accumulated running distance of the vehicle in the running test.

The data storage unit 32 is set in a specified area of the memory and stores various data. Specifically, the data storage unit 32 stores the charging data and battery temperature data output in association with each other from the output unit 233 of the charging system 2 described above, together with identification information for identifying the vehicle V. Furthermore, the data storage unit 32 may also store the mileage data output from the test device control unit 31 described above, in association with the charging data and battery temperature data via the identification information.

In addition, the driving test management device 3 of this embodiment further has the function of an electricity consumption calculation unit 33, as shown in FIG. 2.

The electricity consumption calculation unit 33 acquires the mileage data and the charging data from the data storage unit 32, and calculates the electricity consumption of the vehicle V in the running test using the mileage data and the charging data. Specifically, the electricity consumption calculation unit 33 calculates the electricity consumption C [Wh/km] based on the following formula (1) using the mileage D [km] in the running test indicated by the mileage data and the post-test charge amount E [Wh] indicated by the charging data.
C=Ex/D...(1)
As can be seen from formula (1), the electricity consumption rate means the AC power consumption rate per 1 km traveled.

The electricity consumption data indicating the electricity consumption C calculated by the electricity consumption calculation unit 33 may be output to the outside, or may be stored in the data storage unit 32 in association with the charging data, battery temperature data, and mileage data described above.

According to the test system 100 configured in this way, the output section 233 of the charging system 2 outputs charging data and battery temperature data in association with each other, making it possible to automatically collect the battery charge amount and battery temperature. This not only prevents human error caused by the conventional handwritten recording, but also improves the reliability of the obtained data and leads to a paperless system.

Furthermore, the charging completion determination unit 236 determines whether or not battery charging is complete based on the number of times or the time that the power waveform falls below a predetermined reference value, so that the completion of battery charging can also be determined automatically, which is more effective in preventing human error and improving the reliability of data compared to when an operator must determine the completion of charging.

In addition, the plug monitoring unit 238 sets the power plug being inserted into the vehicle V as the second condition for the charging completion determination unit 236, so that the completion of battery charging can be automatically and more accurately determined.

Furthermore, in a configuration in which the soak end determination unit 237 determines that the soak of the vehicle V has ended when a predetermined condition is satisfied, the predetermined condition includes a condition in which the difference or ratio between the battery temperature indicated by the battery temperature data and the set temperature of the soak chamber is within a predetermined range, so that it is possible to prevent the test from being started in a state in which the battery temperature is significantly different from the set temperature of the soak chamber. This makes it possible to ensure temperature management of the vehicle V at the start of the test.
The present invention is not limited to the above-described embodiment.

For example, as shown in FIG. 6, the data management device 23 may include a notification unit 23A that compares the power waveform with a predetermined threshold value to determine whether the charging state is normal, and notifies the user if it is determined that the charging state is not normal.

When the charging state is normal, the power supplied during charging of the battery is stable, as shown in the upper part of Figure 7. On the other hand, when the charging state is abnormal, the power supplied during charging of the battery increases and decreases and becomes unstable, as shown in the lower part of Figure 7. Note that such power waveforms may be stored, for example, in the data storage unit 32, so that the charging state of the battery can be checked after charging the battery.

Therefore, the notification unit 23A can be configured to acquire the power waveform contained in the charging data, and compare the magnitude of the power indicated by this power waveform with a predetermined threshold value, and, for example, determine that the charging state is normal if the difference or ratio between these is within an acceptable range, and determine that the charging state is abnormal if it exceeds the acceptable range.
The threshold value can be determined based on the power supplied when the charging state is normal. For example, the upper and lower limit powers may be set to be the normal power multiplied by a predetermined rate, or the normal power plus or minus a predetermined power may be set to be the normal power plus or minus a predetermined power.
With this configuration, for example, an operator can be notified of an abnormality occurring when a power plug is not properly inserted into the test specimen or due to external noise.
The threshold value is not limited to the magnitude of the power as described above, but may be the slope of the power waveform.

In addition, among the above-mentioned thresholds, when using a threshold obtained by multiplying the normal power by a specified percentage, the specified percentage can be used without changing it regardless of whether the charging method for the test specimen is normal charging or quick charging. Of course, the specified percentage can be changed depending on the charging method.

On the other hand, when using a threshold obtained by adding or subtracting a predetermined power from the normal power, the predetermined power may be changed according to the charging method for the test specimen. Specifically, a threshold may be set for each of a plurality of charging methods, and the notification unit 23A may be configured to obtain the threshold corresponding to the set charging method.
In this case, the abnormality determination by the notification unit 23A can be applied to a plurality of charging methods.

In addition, the data management device 23 may further include an ambient temperature acquisition unit 23B that acquires ambient temperature data indicating the ambient temperature of the test specimen from a temperature sensor installed in the soak chamber or test chamber, as shown in FIG. 8, and the output unit 233 may output the charging data, battery temperature data, and ambient temperature data in association with each other.
This makes it possible to automatically collect temperatures in the soak chamber and test room, creating a system with high traceability.

Furthermore, as shown in FIG. 9, the data management device 23 may further include a data management unit 23C that stores the charging data output by the output unit 233 in association with the travel distance of the test specimen.
This data management unit 23C is set in a specified area of the memory provided in the data management device 23, and the running distance of the test specimen may be obtained from the running test control unit 31 of the running test management device 3, or from the data storage unit 32.
With this configuration, the data management unit 23C stores the charging data output by the output unit 233 in association with the mileage of the test specimen, so that the power consumption rate (electricity consumption) obtained based on the amount of power consumed and the mileage can also be managed.
In addition, the data management unit 23C may also store the battery temperature data acquired by the battery temperature acquisition unit 232 and the electricity consumption data indicating the electricity consumption C calculated by the electricity consumption calculation unit 33 in association with the charging data.

In addition, as shown in FIG. 10, the data management device 23 may include a battery remaining capacity acquisition unit 23D that acquires remaining capacity data indicating the remaining capacity of the battery, and a charge completion prediction unit 23E that predicts the required charging time required to complete charging of the battery or the charge completion time at which charging is completed based on the remaining capacity data. Note that the remaining capacity data may indicate the SOC (State Of Charge), which indicates the percentage of the remaining capacity of the battery, or may indicate the absolute value of the remaining capacity of the battery.

As an example of the battery remaining capacity acquisition unit 23D, a mode in which remaining capacity data is acquired from the OBD can be given. In addition, as another mode of the battery remaining capacity acquisition unit 23D, the remaining capacity of the battery may be calculated, for example, by subtracting the battery usage amount calculated based on the mileage from the battery capacity when fully charged.

The charging completion prediction unit 23E can also calculate the required charging time or the charging completion time based on the remaining capacity data described above and the charging data acquired by the charging status acquisition unit 231 (specifically, the power supplied to the battery from the charging equipment 21), and output the calculated required charging time or the charging completion time so that the operator can recognize it.

With this configuration, it is possible to predict the time required for charging and the time when charging will be completed, which is useful for scheduling tests, for example.

In addition, while the driving test device 1 is described as being equipped with a chassis dynamometer in the above embodiment, it may also be equipped with a motor dynamometer to which the motor under test is connected, or a powertrain dynamometer to which the drive system under test is connected.

In the above embodiment, the output unit 233 outputs the charging data and the battery temperature data in association with each other. However, the output unit 233 may output the charging data in association with the ambient temperature data acquired by the ambient temperature acquisition unit 23B instead of the battery temperature data or in addition to the battery temperature data.

In addition, some or all of the functions of the driving test management device 3 and some or all of the functions of the data management device 23 may be provided in a common device.

It goes without saying that the present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the spirit of the invention.
