Description

[Technical field]

[0001] The present invention relates to a method and system for managing battery charging data, and more particularly to a method and system capable of determining whether an abnormality has occurred in the charging state of a battery of an electric vehicle. [Background technology]

[0002] In recent years, with the increasing awareness of environmental protection and the advancement of electric vehicle technology, the development of electric vehicles powered by electrical energy has gradually become an important goal in the automotive field, replacing traditional vehicles powered by fossil fuels, and therefore electric vehicles are becoming more and more popular. In order to increase the driving range and willingness to use electric vehicles, many countries and cities have set up charging stations and battery energy stations in public places to provide charging and battery exchange for electric cars and electric motorcycles, making the use of electric vehicles more convenient.

[0003] Generally, batteries are one of the most important costs for manufacturers, and secondary batteries have a limited service life. In some electric vehicles, such as electric motorcycles, when the battery power is insufficient, the power difference between each battery is too large, and / or the remaining life cycles of each battery are significantly different, starting the electric vehicle by combining these batteries will affect the function or life of the vehicle or the battery itself.

[0004] In addition, the high cost of batteries is also one of the main reasons for the high service cost of electric motorcycles. If different charging modes can be planned or different suppliers can be introduced to participate in the ecological chain of electric vehicles according to users' needs, the overall service cost of electric motorcycles can be moderately reduced, which may further increase users' willingness to adopt electric motorcycles. In some cases, allowing users to charge at home allows operators to design more favorable plans to encourage users to adopt electric motorcycles, reducing the use of public power facilities and thereby dispersing power pressure on the power grid. However, in this case, it is necessary to understand the usage and charging status of users to prevent them from entering an abnormal state during charging.

[0017] The following description is of the best contemplated mode for carrying out the invention. This description is made for the purpose of illustrating the general principles of the invention and should not be taken in a limiting sense. It is to be understood that embodiments can be realized in software, hardware, firmware, or any combination thereof.

[0018] FIG. 1 is a schematic diagram showing an embodiment of the electric vehicle battery charging data management system of the present invention. The electric vehicle battery charging data management system 100 includes a battery 110, a power supplement device 120, an electric vehicle 140, and a remote server 130.

It is noted that in some embodiments, the mode includes any one of charging at an electric vehicle, charging at a home charger, charging at a battery energy station, and battery exchange at a battery energy station, or any combination thereof.It should be noted that the above charging modes are merely examples of the present invention, and the present invention is not limited thereto. It should be noted that in some embodiments, the electric vehicle 140 is an electric bike. The electric vehicle 140 records the total mileage of the electric vehicle 140 and / or the driving distance between each battery charging operation. The battery 110, the power supplement device 120, and / or the electric vehicle 140 are directly or indirectly connected to the remote server 130 via a network and execute the electric vehicle battery charging data management method of the present invention, which will be discussed in detail below.

[0019] FIG. 2 is a schematic diagram showing an embodiment of collecting power replenishment record data of the present invention. In this embodiment, when performing a power replenishment operation of a corresponding battery, the power replenishment device 120 can record the power replenishment record data of the corresponding power replenishment operation. The power replenishment device 120 has a network connection capability. The power replenishment device 120 can transmit the power replenishment record data to the remote server 130 through a network 200. It should be noted that in some embodiments, the network 200 is a wired network, a telecommunication network, a wireless network, such as Bluetooth, Wi-Fi network, etc. As mentioned above, in some embodiments, the power replenishment device 120 includes an electric vehicle, a home charger, and / or a battery energy station.

[0020] It should be noted that in some embodiments, when performing a power replenishment operation of the corresponding battery, the battery 110 records power replenishment record data of the power replenishment operation. The battery 110 has a network connection unit. The battery 110 is connected to a network through the network connection unit, and transmits the power replenishment record data to the remote server 130 through the network.

[0021] FIG. 3 is a schematic diagram showing another embodiment of collecting power replenishment record data of the present invention. In this embodiment, the electric vehicle 140 is connected to a mobile device 150, such as a user's smartphone, via a wireless network such as Bluetooth or Wi-Fi network, and transmits the power replenishment record data in the battery and the mileage record to the mobile device 150. The mobile device 150 has a network connection capability and transmits the power replenishment record data to the remote server 130 through the network 300. Similarly, in some embodiments, the network 300 is a wired network, a telecommunication network, or a wireless network, such as Bluetooth or Wi-Fi network. It should be noted that in some embodiments, the remote server 130 can simultaneously manage batteries, electric vehicles, and / or power replenishment devices located at the same or different locations.

[0022] FIG. 4 is a flow chart of a method for managing battery charging data of an electric vehicle according to an embodiment of the present invention.

[0023] First, in step S410, the electric vehicle is used to record the mileage of the electric vehicle. It should be noted that in some embodiments, the mileage is the total mileage of the electric vehicle and / or the driving distance between each charging operation of the battery. In step S420, the power refilling device is used to perform a power refilling operation corresponding to the battery, the power refilling operation including a charging operation or a battery exchange operation. Similarly, in some embodiments, the power refilling device includes an electric vehicle, a home charger, and / or a battery energy station. In step S430, the battery or the power refilling device is used to record power refilling record data of the corresponding power refilling operation. In some embodiments, the power refilling record data includes at least battery identification data corresponding to the battery, power refill information, and / or device identification data of the power refilling device. It is particularly emphasized that the device identification data of the power refilling device is relatively important because the charging mode can be diversified according to the flexibility of the application requirements. The device identification data management of the power refilling device provides a more diversified charging mode application. For example, the battery can record which data is the charging mode applicable to the corresponding user. The charging mode data may record the modes in which the battery is allowed to be supplied, such as charging in an electric vehicle, charging in a home charger, charging in a battery energy station, and battery exchange in a battery energy station, or any one or combination thereof. In a power replenishment operation, the power replenishment device determines whether the battery can be charged based on the charging mode data of the battery and the device identification data of the power replenishment device. Then, in step S440, the remote server is used to obtain the power replenishment record data of the corresponding battery and the mileage of the corresponding electric vehicle. Then, in step S450, it is determined whether the electric vehicle is in an abnormal state of power replenishment based on the power replenishment record data and the mileage of the corresponding electric vehicle.It is worth noting that in some embodiments, when the electric vehicle is in an abnormal power replenishment state, it may mean that the battery recharging status cannot be accurately recorded or obtained. In some embodiments, when the electric vehicle is in an abnormal power replenishment state, it may indicate that the user may have committed fraud during the battery charging operation. For example, if the user modifies the power replenishment record data by cracking, the actual mileage of the electric vehicle may not match the power replenishment record data of the corresponding battery.

[0024] FIG. 5 is a flow chart of a method for determining whether an abnormal condition exists during a charging operation.

[0025] First, in step S510, the remote server calculates the ampere-hour consumption based on the mileage of the corresponding electric vehicle. It should be noted that, as mentioned above, the mileage is the total mileage of the electric vehicle and / or the driving distance between each charging operation of the battery. Then, in step S520, it is determined whether the power supplement information is within a predetermined tolerance range of the ampere-hour consumption. When the power supplement information is within the predetermined tolerance range of the ampere-hour consumption (step S530, yes), the process ends. In other words, the electric vehicle does not have an abnormal state of power supplement. When the power supplement information is not within the predetermined tolerance range of the ampere-hour consumption (step S530, no), in step S540, the remote server determines that the electric vehicle is in an abnormal state of power supplement. Then, in step S550, the remote server generates an alert notification or transmits the alert notification via a network to a user device that is coupled to the corresponding battery identification data.

[0026] 6 is a flow chart of a method for collecting power replenishment record data according to an embodiment of the present invention. In this embodiment, the power replenishment record data in the battery is transmitted to the electric vehicle, and then transmitted by the electric vehicle to a remote server.

[0027] First, in step S610, a battery is electrically coupled to an electric vehicle, for example, an electric bike, to provide electric energy to the electric vehicle. In step S620, the power replenishment record data of the corresponding battery is sent to the electric vehicle. As described above, when a power replenishment operation of the battery is performed, the power replenishment record data of the corresponding power replenishment operation is recorded and stored in the storage unit of the battery. Then, in step S630, the electric vehicle transmits the power replenishment record data and the mileage of the corresponding electric vehicle to a remote server via a network. It is noted that in some embodiments, the electric vehicle transmits the power replenishment record data to the remote server directly via a network, or is connected to a mobile device via a network such as a Bluetooth or Wi-Fi network, and transmits the power replenishment record data to the remote server by the mobile device. It is noted that in some embodiments, in addition to the battery identification data of the corresponding battery, the device identification data of the power replenishment device, and / or the power replenishment information, the power replenishment record data further includes a vehicle identification code of the corresponding electric vehicle and user identification data corresponding to the battery.

[0028] FIG. 7 is a flowchart of a method for collecting power replenishment record data according to another embodiment of the present invention.

[0029] First, in step S710, the wireless connection unit of the battery is used to transmit power replenishment record data to a remote server through a wireless network. In step S720, the electric vehicle is used to transmit the mileage of the electric vehicle to the remote server through the network. It should be noted that the electric vehicle can directly transmit the mileage to the remote server through the network, or can connect to a mobile device through the network and transmit the mileage to the remote server through the mobile device.

[0030] It can be understood that after the remote server receives the power replenishment record data and the mileage, it can execute related applications, such as determining whether the electric vehicle is in an abnormal power replenishment state.

[0031] Therefore, the method and system for managing battery charging data for an electric vehicle determines whether the battery charging status of an electric vehicle is abnormal, thereby improving the accuracy of charging record data collection and preventing fraud.

[0032] The battery charging data management method may take the form of program code (i.e., executable instructions) embodied in a tangible medium, such as a floppy disk, CD-ROM, hard drive, or any other machine-readable storage medium, which when loaded into a machine, such as a computer, and executed, causes the machine to thereby become an apparatus for performing the method. The method may also be embodied in the form of program code transmitted over some transmission medium, such as transmission over electrical wiring, cabling, or optical fiber, which when received, loaded into a machine, such as a computer, and executed, causes the machine to become an apparatus for performing the disclosed method. When implemented on a general-purpose processor, the program code combines with the processor to provide a unique apparatus that operates analogously to application-specific logic circuits.

[0033] Although the present invention has been described by way of example and in terms of preferred embodiments, it is to be understood that the present invention is not limited thereto. Those skilled in the art may still make various changes and modifications without departing from the scope and spirit of the present invention. Therefore, the scope of the present invention is defined and protected by the following claims and their equivalents. [Explanation of symbols]
