Technical Field

[0001] The present invention relates to the field of vehicle technology, and in particular to a charging control method, device, equipment, vehicle and storage medium. Background Art

[0002] With the increasing penetration of new energy vehicles, more and more users are choosing electric vehicles for transportation. The ability to safely recharge electric vehicles is crucial. Some users, particularly those abroad, often use household AC outlets for charging. However, due to the varying current carrying capacity of household outlets, the vehicle control unit often lacks visibility into the AC outlet's current carrying capacity and requests a charging current based on the charging cable's maximum capacity, posing a safety hazard.

[0003] In the related art, the battery pack is charged according to the smaller value among the current upper limit value of the charging device, the current upper limit value of the battery pack itself, and a preset charging current value.

[0004] However, the charging methods in related technologies have low flexibility and poor practicality and user experience. Summary of the Invention

[0005] The present invention provides a charging control method, device, equipment, vehicle and storage medium to solve the problem of low flexibility in vehicle charging methods in related technologies.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0007] In a first aspect, the present invention provides a charging control method, the method comprising:

[0008] In response to a user's selection instruction for a current limit, a first current limit is determined; the charging of the vehicle is controlled so that the current value of the vehicle during charging does not exceed a target current value; wherein the target current value is the minimum value among the first current limit, the second current limit, and the third current limit; the second current limit is the maximum current value that the cable between the charging pile and the charging gun of the charging device can carry; and the third current limit is the maximum current value that the charging pile of the charging device supports to output.

[0009] According to the above technical means, users can independently adjust the upper limit of vehicle charging current according to actual scenarios within a certain range, which enhances the flexibility of adjusting the upper limit of vehicle charging current and can improve the user experience while ensuring the charging efficiency of the vehicle.

[0010] Furthermore, the above-mentioned determination of the first current limit in response to the user's selection instruction for the current limit may include: displaying a current limit adjustment interface, the current limit adjustment interface including an adjustment bar and a determination control of the adjustment bar; and determining the first current limit within the current limit interval corresponding to the adjustment bar in response to the user's sliding operation on the determination control of the adjustment bar.

[0011] According to the above technical means, the display content of the current limit adjustment interface can be limited, so that the user can intuitively adjust the first current limit in the current limit adjustment interface, thereby improving the convenience and efficiency of adjusting the first current limit.

[0012] Furthermore, the above method also includes: when the vehicle and the charging gun are successfully connected, using the second current limit as the upper limit value of the current limit interval corresponding to the adjustment bar; or, when the vehicle and the charging gun are not successfully connected, using the preset maximum current limit as the upper limit value of the current limit interval corresponding to the adjustment bar.

[0013] According to the above technical means, the potential safety risks caused by setting an excessively high current value when the vehicle and the charging gun fail to establish a connection are avoided, the safety of vehicle charging is improved, and a flexible and safe charging current setting method is provided for users.

[0014] Furthermore, the above method also includes: when the vehicle drives out of a preset geographical range including the current location, moving the confirmation control to the first position of the adjustment bar on the current limit adjustment interface, the first position being used to indicate the upper limit value of the current limit interval corresponding to the adjustment bar.

[0015] According to the above technical means, charging safety can be guaranteed and battery performance can be protected.

[0016] Furthermore, the above method also includes: when the vehicle enters a preset geographical range including the current location next time, moving the confirmation control to a second position of the adjustment bar on the current limit adjustment interface, the second position being used to indicate the target current limit in the current limit interval corresponding to the adjustment bar.

[0017] According to the above technical means, when the vehicle enters the preset geographical range, clear feedback is given to the user, further enhancing the user experience.

[0018] Furthermore, the above method also includes: establishing and storing a correspondence between a preset geographical range including the current location and a target current value, wherein the correspondence is used to constrain the current limit value of the vehicle to be the target current limit value when charging within the preset geographical range.

[0019] According to the above technical means, users can avoid setting up multiple times at the same location, thereby simplifying user operations.

[0020] Furthermore, after determining the first current limit value in response to the user's selection instruction for the current limit value, the above method further includes:

[0021] When the target current limit value is equal to the first current limit value, a prompt message for prompting that the setting is successful is issued; or when the target current limit value is not equal to the first current limit value, a prompt message for prompting that the setting is failed is issued.

[0022] According to the above technical means, after the target current limit is set, a prompt message can be issued to prompt the user of the setting result, thereby further enhancing the user experience.

[0023] In a second aspect, the present invention provides a charging control device, which includes: a determination unit and a control unit.

[0024] a determining unit, configured to determine a first current limit value in response to a user's selection instruction for a current limit value;

[0025] A control unit is used to control the charging of the vehicle so that the current value of the vehicle during charging does not exceed the target current value; wherein the target current value is the minimum value among the first current limit, the second current limit, and the third current limit; the second current limit is the maximum current value that the cable between the charging pile and the charging gun of the charging device can carry; and the third current limit is the maximum current value supported by the charging pile of the charging device.

[0027] In a fourth aspect, the present invention further provides a computer-readable storage medium storing a data processing program, which is executed by a processor to perform the method provided in the first aspect and its possible implementations.

[0028] Compared with the related art, the present invention has the following advantages:

[0029] (1) In response to the user's selection instruction for the current limit, a first current limit is determined, which allows the user to independently adjust the upper current limit of the vehicle charging according to the actual scenario within a certain range, thereby enhancing the flexibility of adjusting the upper current limit of the vehicle charging; then, the minimum value is selected as the target current value among the maximum current value that the cable between the charging pile and the charging gun of the charging device can carry, the maximum current value supported by the charging pile of the charging device, and the first current limit set by the user, so as to control the current value of the vehicle during charging to not exceed the target current value, thereby ensuring the charging efficiency and safety of the vehicle while improving the user experience.

[0030] (2) By limiting the display of the current limit adjustment interface, the user can intuitively adjust the first current limit on the current limit adjustment interface, thereby improving the convenience and efficiency of adjusting the first current limit.

[0031] (3) By limiting the upper limit of the current limit range corresponding to the adjustment bar when the vehicle and the charging gun are successfully connected or when the vehicle and the charging gun are not successfully connected, the potential safety risks caused by setting an excessively high current value when the vehicle and the charging gun are not successfully connected are avoided, the safety of the vehicle during charging is improved, and a flexible and safe charging current setting method is provided for users.

[0044] The following description of exemplary embodiments of the present disclosure is made in conjunction with the accompanying drawings, in which various details of the present invention are included to facilitate understanding. These details should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0045] It should be noted that the terms "first", "second", "third", etc. in the claims, description and drawings of the present invention are used to distinguish similar objects and are not used to describe a specific order or sequence. The numbers used in this way are interchangeable where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including", "having" and their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0046] It should be understood that in the embodiments of the present invention, "at least one" refers to one or more, and "more than one" refers to two or more. "And / or" is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent three situations: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the previous and subsequent associated objects are in an "or" relationship. "Including A, B and / or C" means including any one, any two, or any three of A, B, and C.

[0047] It should be understood that in the embodiments of the present invention, "B corresponding to A," "B corresponding to A," "A corresponds to B," or "B corresponds to A" means that B is associated with A and B can be determined based on A. Determining B based on A does not mean determining B based solely on A; B can also be determined based on A and / or other information.

[0048] With the continuous penetration of new energy vehicles, more and more users choose electric vehicles for travel. Whether electric vehicles can be safely recharged is of vital importance. Some users, especially foreign users, often use household sockets for AC charging. However, due to the different current-carrying specifications of household sockets, the vehicle control unit often does not know the current-carrying size of the AC socket, and requests the charging current according to the maximum capacity of the charging cable. For example, the charging cable specification is 16A for on-board charging, and the current-carrying size of the household socket is 10A. Users often use a 10A to 16A conversion connector for charging, which far exceeds the load of the household socket for charging, which brings a very large safety hazard. In the related art, the battery pack is charged according to the smaller value among the current upper limit of the charging equipment, the current upper limit of the battery pack itself, and the preset charging current value.

[0049] However, the charging methods in related technologies have low flexibility and poor practicality and user experience.

[0050] Based on background technical reasons, the present invention provides a charging control method that allows users to autonomously adjust the upper current limit of the vehicle when charging according to the actual scenario within a certain range. For example, in the scenario of charging the vehicle through a household socket, the current limit can be adjusted to 10A to avoid bringing a large load, thereby enhancing the flexibility of adjusting the upper current limit of the vehicle when charging, and can improve the user experience while ensuring the charging efficiency of the vehicle.

[0051] The charging control method provided by the present invention can be executed by an onboard controller or other charging-related controller in a vehicle, and the execution subject of the method is not specifically limited. For ease of description, the following description uses an onboard controller as an example.

[0052] The technical solution of the present invention is described in detail below through specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0053] Figure 1 This is a flow chart of the charging control method provided by the present invention. Figure 1 As shown, the method may include S101-S102.

[0054] S101, determining a first current limit value in response to a user's selection instruction for a current limit value;

[0055] S102. Control the charging of the vehicle so that the current value of the vehicle during charging does not exceed the target current value; wherein the target current value is the minimum value among the first current limit, the second current limit, and the third current limit; the second current limit is the maximum current value that the cable between the charging pile and the charging gun of the charging device can carry; and the third current limit is the maximum current value that the charging pile of the charging device supports to output.

[0056] As a feasible implementation method, a human-computer interaction interface can be output so that the user can determine the first current limit through the human-computer interaction interface. The electronic device determines the first current limit based on the user's operation information for subsequent control of vehicle charging.

[0057] It should be understood that when it is detected that the AC charging gun is connected to the vehicle, the CC line in the charging gun and the CC interface inside the on-board charger can establish a physical connection. There will be a specific resistance value inside the charging cable or on the connector. This resistance value is used to identify the maximum allowable current of the charging cable, that is, the maximum current value that the cable between the charging pile and the charging gun can carry. Different resistance values correspond to different maximum allowable currents. The on-board charger can determine the type of charging cable currently in use and its corresponding maximum allowable current by detecting the resistance value of the CC interface through an internal detection circuit, and obtain the second current limit, that is, the maximum current value that the cable between the above-mentioned charging pile and the charging gun can carry.

[0058] When it is detected that the user has successfully authorized the charging pile, the charging pile can send a pulse width modulation (PWM) waveform signal to the on-board charger through the control guide line. The duty cycle of the signal represents the maximum current value supported by the charging pile, that is, the third current limit.

[0059] After determining the first current limit, the second current limit, and the third current limit, the minimum value among the first current limit, the second current limit, and the third current limit may be selected as the target current value, and then the current value of the vehicle during charging is controlled not to exceed the target current value.

[0060] In some embodiments, Figure 2 This is a schematic diagram of a device connection for implementing a charging control method provided by the present invention. Figure 2 As shown, the device corresponding to the charging control method may include a charging pile output current detection device 201, an intelligent vehicle cabin 202 and an AC charging limit execution device 203.

[0061] The intelligent vehicle cockpit 202 includes an AC charging current control device 2021 , an AC charging current display setting device 2022 and a position positioning device 2023 .

[0062] The AC charging current control device 2021 and the AC charging current display setting device 2022 perform operation instructions and information transmission via the display serial interface (DSI) protocol of the display processing unit.

[0063] The AC charging current control device 2021 and the position positioning device 2023 process operation instructions and information transmission via a universal asynchronous receiver / transmitter (UART).

[0064] The charging pile output current detection device 201 communicates with the AC charging current control device 2021 through a high-speed controller area network (CAN). The AC charging limit execution device 203 also communicates with the AC charging current control device 2021 through a high-speed controller area network. The charging pile output current detection device 201 is connected by an on-board charger and a charging pile through a constant current (CC) line and a control pilot line (CP), forming a detection device for the current size of the external charging pile end. Among them, CC and CP meet the requirements of national standards, the CC interface is a charging control circuit, and the CP interface is a charging pilot circuit. The AC charging limit execution device 203 is composed of an on-board charger control processing unit and a power electronic unit, which limits the AC power size of the charging pile according to the AC charging current control device 2021 to achieve safe AC charging. The charging pile output current detection device 201 can detect the CC resistance in accordance with the national standard GB / T18487.1, thereby determining the second current limit. When the CC resistance is -1.5 kilo-ohms (kΩ), the second current limit is 10 amperes (A); when the CC resistance is -680Ω, the second current limit is 16A; when the CC resistance is -220Ω, the second current limit is 32A; and when the CC resistance is -100Ω, the second current limit is 63A.

[0065] The present invention first responds to the user's instruction to select the current limit, determines the first current limit, and then selects the minimum value as the target current value from the maximum current value that the cable between the charging pile and the charging gun of the charging device can carry, the maximum current value supported by the charging pile of the charging device, and the first current limit set by the user, to control the current value of the vehicle during charging to not exceed the target current value. Therefore, the charging control method provided by the embodiment of the present invention can enable the user to autonomously adjust the upper current limit of the vehicle during charging according to the actual scenario within a certain range, enhance the flexibility of adjusting the upper current limit of the vehicle during charging, and can improve the user experience while ensuring the charging efficiency of the vehicle.

[0066] In some embodiments, a human-machine interaction interface may be output so that the user can determine the first current limit value through the human-machine interaction interface. Figure 3 , Figure 3 The present invention provides Figure 1 A schematic diagram of an implementation flow of S101 in FIG. Figure 3 As shown, Figure 1 The illustrated S101 may include S301 - S302 .

[0067] S301 . Displaying a current limit adjustment interface, where the current limit adjustment interface includes an adjustment bar and a confirmation control of the adjustment bar.

[0068] As a possible implementation method, when it is detected that the charging gun is inserted into the charging port of the electric vehicle, a current limit adjustment interface is displayed.

[0069] For example, see Figure 4 , Figure 4 This is a schematic diagram of a current limit adjustment interface provided by the present invention. Figure 4 As shown, current limit adjustment interface 401 may include an adjustment bar 4011 and a confirmation control 4012 within the adjustment bar. Adjustment bar 4011 allows a user to select a current value by dragging the confirmation control. Adjustment bar 4011 typically has a minimum and a maximum value, representing the allowable range of the current limit. Confirmation control 4012 may be a slider on adjustment bar 4011 that can slide along adjustment bar 4011. The position of confirmation control 4012 corresponds to the currently selected current value.

[0070] As another possible implementation, a current limit adjustment interface may be displayed when a current limit adjustment operation is received.

[0071] It should be understood that the embodiments of the present application do not impose specific restrictions on the current limit adjustment operation. It can be determined that the current limit adjustment operation has been received when the current limit adjustment control is triggered, or it can be determined that the current limit adjustment operation has been received when a voice command related to the current limit adjustment is received.

[0072] S302 : In response to a sliding operation on a determination control of an adjustment bar, determine a first current limit value within a current limit value interval corresponding to the adjustment bar.

[0073] As a possible implementation, the current limit interval corresponding to adjustment bar 4011 represents the range of minimum and maximum values that adjustment bar 4011 allows for selection, such as a continuous range of values from the minimum current to the maximum current. A user can determine a first current limit within the current limit interval corresponding to adjustment bar 4011 by controlling the position of confirmation control 4012 on adjustment bar 4011. For example, a user can drag confirmation control 4012 from left to right on adjustment bar 4011. When the user releases confirmation control 4012, the current value corresponding to the position of confirmation control 4012 is automatically determined as the first current limit.

[0074] As another possible implementation, Figure 4 As shown, the current limit adjustment interface 401 may also include a real-time current value display area 4013. The real-time current value display area 4013 may change as the position of the confirmation control 4012 on the adjustment bar 4011 changes. For example, when the user drags the confirmation control 4012 from left to right on the adjustment bar 4011, the real-time current value displayed in the real-time current value display area 4013 may be observed. When the real-time current value displayed in the real-time current value display area 4013 is the current value expected by the user, the user releases the confirmation control to determine the first current limit.

[0075] As another possible implementation, Figure 4 As shown, current limit adjustment interface 401 may further include a selection control 4014. After adjusting the position of confirmation control 4012 on adjustment bar 4011, the user may determine the first current limit by selecting control 4014. For example, the user may drag confirmation control 4012 from left to right on adjustment bar 4011. When the user releases confirmation control 4012, the current value corresponding to the position of confirmation control 4012 is temporarily set as the first current limit. When the user presses selection control 4014, the current value corresponding to the current position of confirmation control 4012 is determined as the first current limit. This prevents the user from releasing confirmation control 4012 before sliding confirmation control 4012 to the desired position due to error or other reasons, thereby improving the accuracy and efficiency of determining the first current limit.

[0076] As another possible implementation, the current limit adjustment interface 401 may further include a digital input box and a digital control, and the user may determine the first current limit by directly inputting a number, thereby quickly and intuitively determining the first current limit and improving the convenience of determining the first current limit.

[0077] As another possible implementation, after determining the first current limit, the AC charging current display interface can be controlled to display a confirmation message. For example, when the first current limit is determined to be 12A, the AC charging current display interface can be controlled to display "The current limit has been updated to 12A" to give the user clear feedback.

[0078] In a specific embodiment, assuming that the length of the adjustment bar is X and the current charging current limit is Y, the AC charging current display setting device 2022 displays the charging current as 6A to 63A in the factory default state. The AC charging current display setting device 2022 can divide the charging upper limit current length, that is, the adjustment bar length X, into 100 equal granularities, and the value of each granularity is (X-6) / 100. The user slides the confirmation control of the adjustment bar displayed on the AC charging current display setting device 2022 to set the current charging current limit Y. The AC charging current display setting device 2022 can display the setting result Y=[a*(X-6) / 100]+6. Among them, a represents the granularity between the position of the confirmation control and the minimum value of the adjustment bar after the user slides the confirmation control.

[0079] In some embodiments, Figure 5 This is another current limit adjustment interface diagram provided by the present invention. Figure 5 As shown in (A), the length of the adjustment bar is X, the minimum value is 6A, and the current charging current limit is Y. b represents the granularity of dividing the adjustment bar length X into 100 equal parts, and a represents the granularity between the position of the confirmation control and the minimum value of the adjustment bar after the user slides to confirm the control. Figure 5 As shown in (B) in FIG. 5 , when the charging current is displayed as 6A to 16A and the user slides the confirmation control of the adjustment bar to the position a=60, the current charging current limit value Y=12A.

[0080] In an optional embodiment, the method may further include: when the vehicle is successfully connected to the charging gun, using the second current limit as the upper limit of the current limit interval corresponding to the adjustment bar; or,

[0081] When the vehicle fails to establish a connection with the charging gun, the preset maximum current limit is used as the upper limit of the current limit range corresponding to the adjustment bar.

[0082] As a possible implementation method, after detecting that the AC charging gun is connected to the vehicle, the charging pile output current detection device 201 can detect whether the vehicle and the charging gun are well connected through the CC resistance size. If the vehicle and the charging gun are well connected, it means that the vehicle and the charging gun are successfully connected, and the maximum current value that the cable between the charging pile and the charging gun of the charging device can carry, that is, the second current limit, can be read, and the second current limit is used as the upper limit value of the current limit interval corresponding to the adjustment bar 4011. The user can select a specific charging current through the adjustment bar 4011 within the range below this upper limit value. If the vehicle and the charging gun are not well connected, it means that the vehicle and the charging gun have not been successfully connected. At this time, the control charging device cannot obtain the specific information of the vehicle, and a preset maximum current limit can be used as the default value to prevent the setting of too high a current value when the vehicle and the charging gun have not been successfully connected, resulting in potential safety risks.

[0083] For example, when the factory default charging current value displayed on the AC charging display interface of the smart car cockpit is 63A as required by the national standard for conductive charging, the smart car cockpit can provide an AC charging current display interface with a range of 6A to 63A. When the user inserts the charging gun into the charging port of the vehicle, the charging pile output current detection device 201 detects that the connection between the vehicle and the charging gun is intact through the CC resistance size, which means that the vehicle and the charging gun are successfully connected, and the second current limit can be read. For example, if the second current limit is 32A, the current limit range of the adjustment bar can be set to 6A to 32A. The initial position of the confirmation control on the adjustment bar indicates the initial value of the current. The initial value may be the default value (such as 16A), or the initial value may be the minimum value of the adjustment bar. The user can select any current value between 6A and 32A by sliding the confirmation control. After the user plugs in the AC charging gun, the charging pile output current detection device 201 detects through the CC resistance that the vehicle and the charging gun are not properly connected, for example, the interface is damaged, the charging gun is not plugged in tightly, etc. At this time, the specific information of the vehicle or charging gun cannot be obtained. The preset maximum current limit (for example, 63A) can be read and used as the upper limit of the current limit range corresponding to the adjustment bar. The current limit range displayed on the adjustment bar is 6A to 63A.

[0084] As another possible implementation method, when the vehicle is properly connected to the charging gun, the on-board smart cockpit can provide a reminder display text based on the second current limit. For example, when the second current limit is 32A, it can display "The current maximum output capacity of the charging pile is 32A."

[0085] This embodiment limits the second current limit value to the upper limit of the current limit interval corresponding to the adjustment bar when the vehicle and the charging gun are successfully connected; or, when the vehicle and the charging gun are not successfully connected, uses the preset maximum current limit value as the upper limit of the current limit interval corresponding to the adjustment bar. This avoids the potential safety risks caused by setting an excessively high current value when the vehicle and the charging gun are not successfully connected, improves the safety of the vehicle during charging, and provides users with a flexible and safe charging current setting method.

[0086] In an optional embodiment, the above method also includes: establishing and storing a correspondence between a preset geographical range including the current location and the target current value, the correspondence being used to constrain the current limit of the vehicle to the target current limit when charging within the preset geographical range.

[0087] As one possible implementation, when controlling a vehicle to charge at a current that does not exceed a target current value for the first time at a current location, a geographic range can be pre-set based on the current location. For example, a geographic range with a radius of 30 meters centered on the current location can be pre-set. A correspondence between this pre-set geographic range and the target current value can be established and stored. When the vehicle charges within this geographic range, the charging current limit can be set to the target current limit corresponding to the geographic range based on the stored correspondence.

[0088] For example, if area A is a geographical range with geographic location 1 as the center and a radius of 30 meters, the target current value within this range is 32A; area B is a geographical range with geographic location 2 as the center and a radius of 40 meters, the target current value within this range is 16A; area C is a geographical range with geographic location 3 as the center and a radius of 25 meters, the target current value within this range is 8A, the correspondence between the above-mentioned preset geographical ranges and the target current limit values can be stored in a database or configuration file, for example, in the form of key-value pairs for subsequent call.

[0089] This embodiment can avoid the user from setting the target current value multiple times at the same location by establishing and storing the corresponding relationship between the preset geographical range including the current location, thereby simplifying the user operation.

[0090] In an optional embodiment, the above method also includes: when the vehicle drives out of a preset geographical range including the current location, moving the confirmation control to the first position of the adjustment bar on the current limit adjustment interface, the first position being used to indicate the upper limit value of the current limit interval corresponding to the adjustment bar.

[0091] As a possible implementation method, the correspondence between the preset geographical range of the current location and the target current value can be obtained. The position positioning device can obtain the current position information of the vehicle (for example, the latitude and longitude information of the vehicle) in real time, and send the latitude and longitude information of the vehicle to the AC charging current control device through the UART universal asynchronous serial protocol processing operation instruction. After the AC charging current control device receives the latitude and longitude information of the vehicle, it can judge in real time whether the current latitude and longitude information of the vehicle sent by the position positioning device is within the preset geographical range based on the correspondence between the preset geographical range of the current location and the target current value. If it is determined that the current latitude and longitude information of the vehicle sent by the position positioning device is not within the preset geographical range, the confirmation control will be moved to the first position of the adjustment bar on the current limit adjustment interface.

[0092] For example, when the vehicle is controlled to charge at a current of 32A at the current location, the adjustment bar displays the currently available current limit range of 6A to 63A. The current location is within a geographical range centered on geographic location 1 and with a radius of 30 meters, and this geographical range corresponds to 32A. When the vehicle completes charging at a current of 32A at the current location and starts driving, the positioning device can obtain the current latitude and longitude information of the vehicle in real time and send it to the AC charging current control device. The AC charging current control device can determine in real time whether the current latitude and longitude information of the vehicle sent by the positioning device is within the geographical range. If it is determined that the current latitude and longitude information of the vehicle sent by the positioning device is no longer within the geographical range, the confirmation control is moved to the first position of the adjustment bar on the current limit adjustment interface, and the charging current limit of the vehicle is adjusted to 63A.

[0093] As another possible implementation, based on the above embodiment, when it is determined that the vehicle's current latitude and longitude information sent by the positioning device is no longer within the geographic range and the vehicle's charging current limit is adjusted to 63A, a prompt message can be displayed to indicate the change in the vehicle's charging current limit. For example, when the vehicle leaves the preset geographic range that includes the current location, the user interface can be controlled to display a prompt message such as "The vehicle has left the authorized charging area. The charging current limit has been adjusted to 63A."

[0094] As another possible implementation method, based on the above embodiment, when it is determined that the current latitude and longitude information of the vehicle sent by the positioning device is no longer within the geographical range, the display of the adjustment bar can be controlled to prompt the change of the vehicle's charging current limit, for example, by color change or marking to emphasize the current upper limit value.

[0095] In an optional embodiment, the above method may further include: when the vehicle enters a preset geographical range including the current location next time, moving the confirmation control to a second position of the adjustment bar on the current limit adjustment interface, the second position being used to indicate the target current limit in the current limit interval corresponding to the adjustment bar.

[0096] As another possible implementation method, the next time the vehicle enters a preset geographical range including the current location, the target current value can be obtained by obtaining the correspondence between the preset geographical range including the current location and the target current value, and the confirmation control can be moved on the current limit adjustment interface to the second position where the target current limit value is located in the corresponding current limit interval of the adjustment bar.

[0097] If the adjustment bar shows that the currently available current limit range is 6A to 63A, and the current location is within the geographical range set with a radius of 30 meters centered on geographical location 1, this geographical range corresponds to 32A. The vehicle's current location information is obtained in real time through the positioning device. If the vehicle's current latitude and longitude information is determined to be within the preset geographical range, the stored correspondence can be queried to determine that the target current limit corresponding to the geographical range is 32A. On the current limit adjustment interface, move the confirmation control to the second position of the adjustment bar to adjust the vehicle's charging current limit to 32A.

[0098] Based on the above embodiment, if the preset geographic range including the current location is Area A, when the vehicle is determined to have entered Area A based on the vehicle's current latitude and longitude information transmitted by the positioning device, and the vehicle's charging current limit is adjusted to 32A, a prompt message can be controlled to be displayed to indicate the change in the vehicle's charging current limit. For example, when the vehicle enters the preset geographic range including the current location, the user interface can be controlled to display a prompt message such as "Current Location: Area A, Charging Current Limit: 32A" to inform the user of the current charging status.

[0099] This embodiment provides clear user feedback when a vehicle enters or exits a preset geographic range, such as displaying a prompt or changing the appearance of UI elements, enhancing the user experience. This helps improve user experience and safety, and is particularly useful in unmanned smart charging station scenarios.

[0100] In one specific embodiment, when a vehicle first enters a preset geographic range that includes the current location, a correspondence between the preset geographic range that includes the current location and the target current value can be established and stored. When the vehicle exits the preset geographic range that includes the current location, a confirmation control is moved on the current limit adjustment interface to the upper limit of the current limit interval corresponding to the adjustment bar, i.e., the aforementioned first position. When the vehicle next enters the preset geographic range that includes the current location, the stored correspondence can be queried to determine the target current limit corresponding to the geographic range, and the confirmation control is moved on the current limit adjustment interface to a second position of the adjustment bar, which is used to indicate the target current limit within the current limit interval corresponding to the adjustment bar.

[0101] In some embodiments, Figure 6 This is a schematic diagram of an implementation process of a charging control method provided by the present invention. Figure 6 As shown, the adjustment bar shows that the currently available current limit range is 6A to 16A. When the vehicle enters the preset geographical range including the current location for the first time, a correspondence between the preset geographical range including the current location and the target current value (12A) can be established and stored. When the vehicle leaves the preset geographical range including the current location, the confirmation control is moved to the upper limit value (16A) of the current limit range corresponding to the adjustment bar on the current limit adjustment interface. When the vehicle enters the preset geographical range including the current location next time, the stored correspondence can be queried to determine that the target current limit corresponding to the geographical range is 12A, and the confirmation control is moved to the position corresponding to 12A on the adjustment bar on the current limit adjustment interface, thereby adjusting the vehicle's charging current limit to 12A.

[0102] In an optional embodiment, after determining the first current limit in response to the user's selection instruction for the current limit, the above method may further include: when the target current limit is equal to the first current limit, issuing a prompt message to indicate that the setting is successful; or, when the target current limit is not equal to the first current limit, issuing a prompt message to indicate that the setting has failed.

[0103] As a possible implementation method, after determining the first current limit in response to the user's selection instruction for the current limit, the target current limit can be compared with the first current limit. When the target current limit is equal to the first current limit, a prompt message can be issued to indicate that the setting is successful, for example, the AC charging current display interface is controlled to display the prompt message "Setting successful". When the target current limit is not equal to the first current limit, a prompt message can be issued to indicate that the setting has failed, for example, the AC charging current display interface is controlled to display the prompt message "Setting failed".
