[0036] The example embodiments will be described in detail herein with reference to the attached drawings. In the following description, the same numbers are used to designate the same elements, unless otherwise indicated. The embodiments described in the following example embodiments are not representative of all embodiments consistent with one or more embodiments of the present specification. Rather, they are merely examples of devices and methods consistent with some aspects of one or more embodiments of the present specification, as detailed in the appended claims.

[0037] It should be noted that the steps of the corresponding methods are not necessarily performed in the order shown and described in the present specification in other embodiments. In some other embodiments, the steps included in the methods can be more or less than those described in the present specification. In addition, a single step described in the present specification can be divided into multiple steps for description in other embodiments, and multiple steps described in the present specification can be combined into a single step for description in other embodiments.

[0038] With the development of new energy vehicles, pure electric vehicles have become an important part of the industry. Compared with the convenience of refueling for fuel vehicles, there are many problems in charging electric vehicles at the present stage. For example, urban public charging piles are not evenly distributed, it is difficult to charge on highways during holidays; slow charging piles and fast charging piles on the market cannot be used universally, etc.

[0039] Due to the above problems, it is very likely that the electric vehicle will run out of power, and there is no suitable charging pile nearby. The mobile charging device can solve the problem of the user's electric vehicle in urgent need of power.

[0040] The mobile charging device can be composed of a charge-discharge battery and multiple intelligent modules. The mobile charging device can connect the electric vehicle through the charging gun and charge the electric vehicle according to the user's required charging capacity.

[0041] Figure 1 is a schematic diagram of a mobile charging device provided by an exemplary embodiment, as Figure 1 The mobile charging device shown in the figure can include a 102 intelligent display screen, a 104 charge-discharge socket, and a 106 charge-discharge battery body. The user can input the degree of the required charging capacity and control the start and stop of the mobile charging device through the intelligent display screen. The user can connect the charging gun to charge the mobile charging device through the charge-discharge socket, or charge the electric vehicle. The mobile charging device can connect multiple charge-discharge battery bodies according to the user's needs.

[0042] The mobile charging device can be Figure 1 operated by relevant staff and charged for the electric vehicle, or additional intelligent modules can be added as a mobile energy storage robot and automatically charged for the electric vehicle. The mobile charging device can also include a smart vehicle for mobile charging, or a charging device mounted on a smart vehicle. The specific form of the mobile charging device is not limited in this specification.

[0043] In actual application, the staff needs to check the remaining power of the vehicle to be charged and manually input the required charging capacity through the mobile charging device to charge the vehicle to be charged.

[0044] Therefore, the present application proposes a technical solution for automatically obtaining the battery state information of the vehicle to be charged by the mobile charging device through short-range wireless communication hardware to charge the vehicle to be charged.

[0045] In implementation, the first short-range wireless communication hardware communicates with the vehicle to be charged through short-range wireless communication, sends an information acquisition instruction to the vehicle to be charged to trigger the vehicle to be charged to execute the information acquisition instruction, obtains the battery state information of the vehicle to be charged, and communicates with the mobile charging device through short-range wireless communication to return the battery state information to the mobile charging device.

[0046] Based on the battery state information, the required charging capacity is determined, and the vehicle to be charged is charged based on the required charging capacity.

[0047] Figure 2A flowchart of vehicle charging based on short-range wireless communication technology provided by an example embodiment.

[0048] As shown in Figure 2 The method can include the following steps:

[0049] In step 202, short-range wireless communication is performed between the first short-range wireless communication hardware and the vehicle to be charged, and an information acquisition instruction is sent to the vehicle to be charged to trigger the vehicle to be charged to execute the information acquisition instruction, acquire the battery status information of the vehicle to be charged, and perform short-range wireless communication with the mobile charging device to return the battery status information to the mobile charging device.

[0050] In this specification, the mobile charging device is equipped with first short-range wireless communication hardware. The short-range wireless communication hardware can exchange data when it is close to the vehicle to be charged based on radio frequency identification (RFID) technology. The short-range wireless communication hardware can be mounted on the mobile charging device or the charging gun connected to the mobile charging device, and data exchange can be performed through the data bus mounted on the charging gun.

[0051] In an embodiment, the short-range wireless communication hardware can include communication hardware implemented based on NFC (Near Field Communication) technology.

[0052] In actual applications, the power delivery personnel can deliver the mobile charging device to the location of the vehicle to be charged for charging by a delivery vehicle, or the intelligent route-finding module mounted on the mobile charging device can automatically go to the location of the vehicle to be charged for charging.

[0053] When the power delivery personnel delivers the mobile charging device to the vehicle to be charged, the mobile charging device can be manually operated to send an information acquisition instruction to the vehicle to be charged. When the mobile charging device arrives near the vehicle, it can also automatically identify the vehicle to be charged and send an information acquisition instruction to the vehicle to be charged. When the vehicle to be charged receives the information acquisition instruction, it can execute the information acquisition instruction to acquire the battery status information of the vehicle to be charged and perform short-range wireless communication with the mobile charging device to return the battery status information to the mobile charging device.

[0054] In this specification, the battery status information of the vehicle to be charged can include the remaining battery capacity, the lowest single-cell voltage, the highest single-cell voltage, the highest battery temperature, the lowest battery temperature, etc., so that the mobile charging device can determine the charging amount based on the battery status information.

[0055] In an embodiment, the to-be-charged vehicle can execute the information acquisition instruction, acquire the battery status information of the to-be-charged vehicle from the battery management system carried by the to-be-charged vehicle, and perform short-range wireless communication with the mobile charging device, transmit the battery status information to the second short-range wireless communication hardware carried by the to-be-charged vehicle, convert the battery status information into a data transmission format supported by the short-range wireless communication by the second short-range wireless communication hardware, and return to the mobile charging device.

[0056] In an embodiment, the to-be-charged vehicle can acquire the CAN message transmitted by the battery management system through the CAN bus, wherein the CAN message comprises the battery status information of the to-be-charged vehicle; the to-be-charged vehicle can convert the battery status information acquired from the battery management system into a CAN message and transmit the CAN message to the second short-range wireless communication hardware carried by the to-be-charged vehicle through the CAN bus. The second short-range wireless communication hardware carried by the to-be-charged vehicle parses the CAN message, acquires the battery status information of the to-be-charged vehicle, and further converts the battery status information into a data transmission format supported by the short-range wireless communication, and returns to the mobile charging device through short-range wireless communication.

[0057] Figure 3 FIG. 1 is a schematic diagram of a to-be-charged vehicle acquiring battery status information according to an example embodiment. As shown in FIG. 1, the central gateway of the to-be-charged vehicle can acquire the CAN message containing the battery status information transmitted by the battery management system through the CAN bus from the battery management system, and transmit the CAN message to the second short-range wireless communication hardware. The second short-range wireless communication hardware parses the CAN message and converts the CAN message into a data transmission format supported by the short-range wireless communication, and returns to the mobile charging device. Figure 3

[0058] In an embodiment, the mobile charging device can further perform short-range wireless communication with the portable control terminal adapted to the to-be-charged vehicle through the first short-range wireless communication hardware.

[0059] The portable control terminal adapted to the to-be-charged vehicle can comprise portable control hardware supporting the short-range wireless communication. For example, the key hardware corresponding to the to-be-charged vehicle with short-range wireless communication function. Alternatively, the portable control terminal adapted to the to-be-charged vehicle can further comprise a control program implemented based on the short-range wireless communication hardware carried by the mobile terminal. For example, the NFC communication program carried by the smart phone, and the like.

[0060] ​The mobile charging device can send an information acquisition command to the portable control terminal via the first short-range wireless communication hardware. The portable control terminal then conducts short-range wireless communication with the vehicle to be charged, forwarding the information acquisition command to the vehicle to be charged. This triggers the vehicle to execute the information acquisition command, acquire the battery status information of the vehicle, and conduct short-range wireless communication with the portable control terminal. The battery status information is then returned to the portable control terminal, which in turn conducts short-range wireless communication with the mobile charging device to return the battery status information to the mobile charging device.

[0061] Figure 4 This is an exemplary embodiment illustrating a scenario of short-range wireless communication via a portable control terminal. For example... Figure 4 As shown, the mobile charging device can conduct short-range wireless communication with a portable control terminal through its own first short-range wireless communication hardware, and trigger the portable control terminal to conduct short-range wireless communication with the second short-range wireless communication hardware on the vehicle to be charged, so that the vehicle to be charged can return the battery status information to the portable control terminal, and the portable control terminal can further conduct short-range wireless communication with the mobile charging device to return the battery status information to the mobile charging device.

[0062] Step 204: Based on the battery status information, determine the amount of energy to be charged, and charge the vehicle to be charged based on the amount of energy to be charged.

[0063] After acquiring the battery status information of the vehicle to be charged, the aforementioned mobile charging device can determine the amount of charge to be made based on the battery status information and charge the vehicle accordingly. The mobile charging device can acquire the remaining battery power and the maximum battery capacity of the vehicle to be charged to determine the amount of charge to be made. The mobile charging device can also determine a suitable charging amount for the vehicle to be charged by using other parameters such as the battery's maximum temperature and maximum voltage, through a preset algorithm for determining the amount of charge to be made, thereby protecting the battery condition of the vehicle. The preset algorithm for determining the amount of charge to be made will not be described in detail in this specification.

[0064] This application utilizes short-range wireless communication hardware integrated into a mobile charging device to send an information acquisition command to the vehicle to be charged. This triggers the vehicle to execute the information acquisition command and return the battery status information to the mobile charging device. This allows the mobile charging device to quickly and accurately obtain the battery status information of the vehicle, determine the amount of charge to be applied based on the battery status information, and then charge the vehicle based on that amount of charge.
