Description

Battery charging information management method and system for electric vehicles

The present invention relates to a method and system for managing battery charging information of electric vehicles, and in particular to a method and system for determining whether an abnormality has occurred in the battery charging status of an electric vehicle.

In recent years, with the rise of environmental awareness and the advancement of electric vehicle technology, the development of electric vehicles powered by electricity to replace traditional vehicles powered by fossil fuels has gradually become an important goal in the automotive field, making electric vehicles more and more popular. In order to improve the range and willingness of electric vehicles, many countries or cities have begun to plan to set up charging stations and battery energy stations in public places to provide electric cars and/or electric motorcycles with charging or battery exchange, making the use of electric vehicles more convenient.

Generally speaking, batteries are one of the most important costs for operators, and rechargeable batteries have a limited life cycle. For some electric vehicles, such as electric motorcycles, when the battery power is insufficient, the power of individual batteries varies greatly, and/or the life cycle of individual batteries varies greatly, if the user uses a combination of these batteries to start the electric vehicle, it will affect the function or life of the vehicle or the battery itself.

On the other hand, the high cost of batteries is also one of the main reasons for the high service costs of electric scooters. If different charging modes can be planned according to user needs, or even different suppliers are introduced to join the electric vehicle ecosystem, the overall service costs of electric scooters may be reduced appropriately, further increasing users' willingness to adopt electric scooters. In some cases, if users can charge at home, operators can design more favorable plans to encourage users to adopt electric scooters to reduce the use of public charging equipment and thus disperse the power pressure of the power grid. However, in this case, it is necessary to obtain the user's battery usage and charging situation to avoid abnormal conditions during the charging operation.

Therefore, one purpose of the present invention is to provide a battery charging information management method for electric vehicles.

Therefore, the battery charging information management method of the electric vehicle of the present invention is applicable to an electric vehicle. First, the electric vehicle is used to record the mileage of the electric vehicle. Then, a power charging device is used to perform a charging operation of a corresponding battery, wherein the battery is used to provide electrical energy to the electric vehicle, and the charging operation includes a charging operation or a battery exchange operation. The battery or the power charging device is used to record a charging record data corresponding to the charging operation, wherein the charging record data at least includes a battery identification data and a power charging information of the corresponding battery. Afterwards, a remote server is used to obtain the charging record data of the corresponding battery and the mileage of the corresponding electric vehicle, and based on the charging record data and the mileage of the corresponding electric vehicle, it is determined whether the electric vehicle has an abnormal charging state.

In some embodiments, the remote server calculates a consumption ampere-hour according to the mileage of the corresponding electric vehicle, and determines whether the power replenishment information falls within a predetermined tolerance range of the consumption ampere-hour according to the consumption ampere-hour. When the power replenishment information does not fall within the predetermined tolerance range of the consumption ampere-hour, the remote server determines that the electric vehicle is in the abnormal charging state.

In some embodiments, when the battery replenishment information does not fall within the predetermined tolerance range of the consumed ampere-hours, the remote server generates a warning notification, or sends a warning notification to a user device bound to the corresponding battery identification data via a network.

In some embodiments, the battery is electrically coupled to the electric vehicle to provide electrical energy to the electric vehicle. The battery transmits the charging record data to the electric vehicle, and the electric vehicle transmits the charging record data and the mileage to the remote server via a network. The electric vehicle directly transmits the charging record data and the mileage to the remote server via the network, or is connected to a mobile device via the network, and transmits the charging record data and the mileage to the remote server via the mobile device.

In some embodiments, a wireless connection unit on the battery is used to transmit the charging record data to the remote server via a wireless network. The electric vehicle is used to transmit the mileage to the remote server via a network. The electric vehicle directly transmits the mileage to the remote server via the network, or is connected to a mobile device via the network, and the mileage is transmitted to the remote server via the mobile device.

In some embodiments, the power charging device includes one or any combination of an electric vehicle, a household charger, and a battery energy station.

Another purpose of the present invention is to provide a battery charging information management system for electric vehicles.

Therefore, the battery charging information management system of the electric vehicle of the present invention includes an electric vehicle, a battery, a power charging device, and a remote server. The electric vehicle records a mileage corresponding to the electric vehicle. The battery provides electrical energy to the electric vehicle. The power charging device is coupled to the battery to perform a charging operation corresponding to the battery. The charging operation includes a charging operation or a battery exchange operation. The battery or the power charging device records a charging record data corresponding to the charging operation, wherein the charging record data at least includes a battery identification data and a power charging information corresponding to the battery. The remote server obtains the charging record data of the corresponding battery and the mileage of the corresponding electric vehicle, and determines whether the electric vehicle has an abnormal charging state based on the charging record data and the mileage of the corresponding electric vehicle.

In some embodiments, the remote server calculates a consumption ampere-hour according to the mileage of the corresponding electric vehicle, and determines whether the power replenishment information falls within a predetermined tolerance range of the consumption ampere-hour according to the consumption ampere-hour, and when the power replenishment information does not fall within the predetermined tolerance range of the consumption ampere-hour, the remote server determines that the electric vehicle is in the abnormal charging state.

In some embodiments, when the power replenishment information does not fall within the predetermined tolerance range of the consumed ampere-hours, the remote server generates a warning notification, or transmits the warning notification to a user device bound to the corresponding battery identification data via a network.

The above method of the present invention can exist in the form of program code. When the program code is loaded and executed by a machine, the machine becomes a device for implementing the present invention.

The effect of the present invention is that: through the battery charging information management method and system of the electric vehicle in this case, it is possible to judge whether the battery charging status of the electric vehicle is abnormal, thereby increasing the accuracy of the charging record data collection and avoiding fraudulent behavior.

Figure 4 shows a method for managing battery charging information for an electric vehicle according to an embodiment of the present invention.

First, as in step S410, the electric vehicle is used to record a mileage corresponding to the electric vehicle. It is worth noting that, in some embodiments, the aforementioned mileage may be the total mileage of the electric vehicle, and/or the mileage between each charging operation of the battery. Next, as in step S420, a power charging device is used to perform a charging operation of a corresponding battery, wherein the charging operation may include a charging operation or a battery exchange operation. Similarly, in some embodiments, the power charging device may include an electric vehicle, a household charger, and/or a battery energy station. As in step S430, the battery or the power charging device is used to record a charging record data corresponding to the charging operation. In some embodiments, the charging record data includes at least a battery identification data of the corresponding battery, a power charging information, and/or a device identification data of the power charging device. It must be particularly emphasized that the charging type can be diversified in response to the flexibility of application requirements, so the device identification data of the power charging device is relatively important. Through the management of the device identification data of the power charging device, more diversified charging type applications can be provided. For example, the battery can record a charging mode data applicable to the corresponding user. The charging mode data may record the type of power charging allowed for the battery, such as charging in the electric vehicle, charging at a home charger, charging at a battery energy station, and battery exchange at a battery energy station, or any one or a combination thereof. During the charging operation, the charging mode data of the battery and the device identification data of the power charging device may be used to determine whether the battery can be charged on the power charging device. Then, as in step S440, a remote server is used to obtain the charging record data of the corresponding battery and the mileage of the corresponding electric vehicle. Thereafter, as in step S450, it is determined whether the electric vehicle has an abnormal charging state according to the charging record data and the corresponding mileage of the electric vehicle. It is worth noting that in some embodiments, when the electric vehicle has an abnormal charging state, it may indicate that the battery charging situation cannot be correctly recorded or obtained. In some embodiments, when the electric vehicle has an abnormal charging state, it may indicate that the user may have committed fraud in the battery charging operation. For example, if the user modifies the charging record data by cracking, it may cause the actual mileage of the electric vehicle to be inconsistent with the charging record data of the corresponding battery.

Figure 5 shows a method for determining abnormal charging status according to an embodiment of the present invention.

First, as in step S510, the remote server calculates a consumed ampere-hour (Ah) according to the mileage of the corresponding electric vehicle. It is noted that, as mentioned above, the mileage can be the total mileage of the electric vehicle and/or the mileage between each charging operation of the battery. Next, as in step S520, it is determined whether the power replenishment information falls within a predetermined tolerance range of the consumed ampere-hour according to the consumed ampere-hour. When the power replenishment information falls within the predetermined tolerance range of the consumed ampere-hour (such as the "Yes" process of step S530 in Figure 5), the process ends. In other words, the electric vehicle does not have the abnormal charging state. When the power replenishment information does not fall within the predetermined tolerance range of the ampere-hour consumption (such as the "No" process of step S530 in FIG. 5), as shown in step S540 in FIG. 5, the remote server determines that the electric vehicle is in the abnormal charging state. Then, as shown in step S550, the remote server generates a warning notification, or transmits the warning notification to a user device bound to the corresponding battery identification data via a network.

FIG. 6 shows a method for collecting charging record data according to an embodiment of the present invention. In this embodiment, the charging record data in the battery can be transmitted to the electric vehicle, and then transmitted to the remote server through the electric vehicle.

First, as in step S610, the battery is electrically coupled to an electric vehicle, such as the electric motorcycle, to provide electric energy to the electric vehicle. As in step S620, the charging record data corresponding to the battery is transmitted to the electric vehicle. As mentioned above, when the charging operation of the battery is performed, the charging record data corresponding to the charging operation will be recorded and stored in the storage unit of the battery. Then, as in step S630, the electric vehicle transmits the charging record data and the mileage of the electric vehicle to a remote server via a network. It is worth noting that in some embodiments, the electric vehicle can directly transmit the charging record data and the mileage of the corresponding electric vehicle to the remote server through the network, or connect to a mobile device through a network such as Bluetooth or Wi-Fi, and transmit the charging record data and the mileage to the remote server through the mobile device. It should be noted that in some embodiments, in addition to a battery identification data corresponding to the battery, a device identification data of the power charging device, and/or a power charging information, the charging record data may further include a vehicle identification code corresponding to the electric vehicle and a user identification data corresponding to the battery.

Figure 7 shows a method for collecting power-on record data according to another embodiment of the present invention.

First, as in step S710, a wireless connection unit on the battery is used to transmit the charging record data to the remote server via a wireless network. In addition, as in step S720, the electric vehicle is used to transmit the mileage to the remote server via a network. The electric vehicle can directly transmit the mileage to the remote server via the network, or connect to a mobile device via the network, and transmit the mileage to the remote server via the mobile device.

It should be noted that after the remote server receives the charging record data and the mileage, it can perform related applications, such as determining whether the electric vehicle has an abnormal charging state.

Therefore, through the battery charging information management method and system of the electric vehicle in this case, it is possible to determine whether the battery charging status of the electric vehicle is abnormal, thereby increasing the accuracy of the charging record data collection and avoiding fraudulent behavior.

The method of the present invention, or a specific form or part thereof, may exist in the form of program code. The aforementioned program code may be contained in a physical medium, such as a floppy disk, an optical disk, a hard disk, or any other machine-readable (such as computer-readable) storage medium, or a computer program product that is not limited to an external form, wherein when the program code is loaded and executed by a machine, such as a computer, the machine becomes a device for participating in the present invention. The program code may also be transmitted through some transmission media, such as wires or cables, optical fibers, or any transmission type, wherein when the program code is received, loaded and executed by a machine, such as a computer, the machine becomes a device for participating in the present invention. When implemented on a general-purpose processing unit, the code combines with the processing unit to provide a unique device that operates like an application-specific logic circuit.

The computer program product of the present invention is loaded into a machine to execute a battery charging information management method for an electric vehicle. The method is applicable to an electric vehicle. The computer program product includes a first program code, a second program code, a third program code, a fourth program code, and a fifth program code. The first program code is used to use the electric vehicle to record a driving mileage of the corresponding electric vehicle. The second program code is used to use a power charging device to execute a charging operation of a corresponding battery, wherein the battery is used to provide electric energy to the electric vehicle, and the charging operation includes a charging operation or a battery exchange operation. The third program code is used to use the battery or the power charging device to record a charging record data corresponding to the charging operation, wherein the charging record data at least includes a battery identification data and a power charging information corresponding to the battery.

The fifth program code is used to use the remote server to determine whether the electric vehicle has an abnormal charging state based on the charging record data and the mileage of the corresponding electric vehicle.

However, the above is only an example of the implementation of the present invention, and it cannot be used to limit the scope of the implementation of the present invention. All simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification are still within the scope of the patent of the present invention.
