[0002] With the development of new energy vehicles, it is necessary to increase the charging speed of new energy vehicles in order to improve the user charging experience and product competitiveness. The charging speed of new energy vehicles depends on the charging speed of the battery, and the charging speed of the battery varies with temperature. How to adjust the battery temperature to increase the charging speed of the battery is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0003] Embodiments of the present application provide a regulation method, an electronic device, and a communication system to reduce vehicle charging time and increase battery charging speed, thereby improving the user's charging experience. [Means for solving the problem]

[0004] To achieve the aforementioned objectives, the following technical solutions are used in the embodiments of this application.

[0005] According to a first aspect, an embodiment of the present application provides an adjustment method. The method may be executed by an electronic device or by a component (e.g., a chip, a chip system, or a processor) disposed in the electronic device. An example in which the method is executed by the electronic device will be described below. The method includes a step of receiving a first message by the electronic device, the first message instructing the electronic device to adjust a temperature of a battery of a vehicle to a target temperature. The electronic device adjusts the temperature of the battery of the vehicle based on the first message to adjust the temperature of the battery of the vehicle to the target temperature when the vehicle arrives at a charging station.

[0006] The target temperature may be the temperature of the battery at which the battery will be charged at the fastest rate. The target temperature may be a specific value or a range of values. For example, the target temperature may be between 25°C and 40°C.

[0007] The first message may be an instruction message. For example, the first message may be instruction information or request information. Alternatively, the first message may be a content message. For example, the first message may include vehicle information and / or charging station information.

[0008] In this way, the battery temperature is regulated before the vehicle arrives at the charging station, reducing the time required to regulate the temperature. When the vehicle arrives at the charging station, the battery temperature has been regulated to the target temperature, allowing the vehicle to be charged at a high charging rate when it arrives at the charging station. Overall, the vehicle charging time is reduced and the battery charging rate is increased, thereby improving the user's charging experience.

[0009] In one specific implementation, the first message is generated if a first condition is met before the vehicle arrives at the charging station.

[0010] In one specific implementation, the first condition includes at least one of the following: the distance between the vehicle and the charging station is less than or equal to a first threshold, and / or the estimated time for the vehicle to arrive at the charging station is less than or equal to a second threshold; the power of a target charging pile in the charging station is greater than a third threshold, and / or the current of the target charging pile is greater than or equal to a fourth threshold, and / or the voltage of the target charging pile is greater than or equal to a sixth threshold; and the remaining charge of the vehicle's battery after the vehicle arrives at the charging station is greater than a fifth threshold.

The first message instructs adjusting the temperature of the vehicle's battery to a target temperature. The electronic device adjusts the temperature of the vehicle's battery based on the first message to adjust the temperature of the vehicle's battery to the target temperature when the vehicle arrives at the charging station.

[0015] In this way, the battery temperature is regulated before the vehicle arrives at the charging station, reducing the time required to regulate the temperature. When the vehicle arrives at the charging station, the battery temperature has been regulated to the target temperature, allowing the vehicle to be charged at a high charging rate when it arrives at the charging station.

[0062] The charging speed of a new energy vehicle depends on the battery charging rate, which is related to the battery temperature. Normally, the charging rate is high when the battery temperature is between 25°C and 40°C. For example, if the battery is at a normal temperature of 25°C, it takes A minutes to charge the battery to 50% capacity. If the battery is at a low temperature of -10°C, it takes 6*A minutes to charge the battery to 50% capacity. Therefore, to increase the battery charging rate, it is necessary to adjust the battery temperature.

[0063] 1A is a functional block diagram of a new energy vehicle 100 for regulating the temperature of a battery. The new energy vehicle 100 may include a battery management system (BMS) 110, a vehicle domain control (VDC) system 120, and a thermal management system 130. The battery management system 110 may include a battery 111. The thermal management system 130 is configured to regulate the temperature of electrochemical cells of the battery. The vehicle domain control system 120 is configured to control the thermal management system to regulate the temperature of electrochemical cells of the battery 111 in the battery management system 110.

[0064] Specifically, when a new energy vehicle is in a charging state, the battery management system or vehicle area control system determines that the vehicle is in a charging state and that the battery temperature is below 25°C. In this case, the vehicle area control system controls the thermal management system to operate to regulate the temperature of the battery's electrochemical cells in the battery management system so that the temperature is maintained between 25°C and 40°C. However, regulating the battery temperature takes a certain amount of time. In addition, regulating the battery temperature during the charging process may result in the temperature of the battery's electrochemical cells being regulated while the battery is being charged. This still results in a problem of a slow battery charging rate.

[0065] To increase the charging rate of a battery, one embodiment of the present application provides an adjustment method. The method includes: receiving a first message, where the first message instructs adjusting the temperature of a battery of a vehicle to a target temperature; and adjusting the temperature of the battery of the vehicle based on the first message so that the temperature of the battery of the vehicle is adjusted to the target temperature when the vehicle arrives at a charging station. In this way, the temperature of the battery is adjusted before the vehicle arrives at the charging station, and the time for adjusting the temperature is shortened. When the vehicle arrives at the charging station, the temperature of the battery has been adjusted to the target temperature, so that the vehicle can be charged at a high charging rate when it arrives at the charging station. Overall, the charging time of the vehicle is shortened and the charging rate of the battery is increased, thereby improving the user's charging experience.

[0066] FIG. 1B is a functional block diagram of another new energy vehicle 100 according to an embodiment of the present application. The new energy vehicle 100 may include the functional modules shown in FIG. 1A, and the new energy vehicle 100 may further include a map application 140. The map application 140 is configured to provide vehicle information and / or charging station information to the vehicle area control system 120. In one embodiment, the coordination method provided in the embodiment of the present application may be applied to an electronic device. The electronic device may include various product forms in the vehicle field, such as a thermal management system, a vehicle area control system, an on-board chip, and an on-board device (e.g., an on-board infotainment system, an on-board computing platform, a vehicle, or a server (virtual or physical)). Various application scenarios are described in detail below.

[0067] In the first application scenario, the electronic device is a thermal management system.

[0068] For example, before a vehicle arrives at a charging station, the thermal management system 130 shown in FIG. 1B receives a first message. The first message instructs the temperature of the vehicle's battery to be adjusted to a target temperature when the vehicle arrives at the charging station. The target temperature may be 25°C to 40°C. The thermal management system adjusts the temperature of the vehicle's battery based on the first message to adjust the temperature of the vehicle's battery to the target temperature when the vehicle arrives at the charging station.

[0069] The first message may be sent to the thermal management system 130 by the battery management system 110 of the new energy vehicle 100 shown in Fig. 1B, or may be sent to the thermal management system 130 by the vehicle area control system 120 of the new energy vehicle 100 shown in Fig. 1B, or may be sent to the thermal management system 130 by another device (i.e., a device other than the new energy vehicle, such as a mobile phone or a server). Details will be described below.

[0070] In the first case, the battery management system sends a first message to the thermal management system.

[0071] Before the vehicle arrives at the charging station, the vehicle area control system 120 shown in FIG. 1B obtains information such as the distance between the vehicle and the charging station, the estimated time the vehicle will arrive at the charging station, the power of each charging pile and each charging pile in the charging station, the current of the charging pile in the charging station, the voltage of the charging pile in the charging station, and the state of charge of the vehicle's battery after the vehicle arrives at the charging station. Specifically, the map application 140 shown in FIG. 1B transmits vehicle information and / or charging station information to the vehicle area control system 120. The vehicle area control system determines whether a first condition is met based on the aforementioned information. The first condition includes at least one of the following: a distance between the vehicle and the charging station is less than or equal to a first threshold, and / or an estimated time for the vehicle to arrive at the charging station is less than or equal to a second threshold; a power of a target charging pile in the charging station is greater than a third threshold, and / or a current of the target charging pile is greater than or equal to a fourth threshold, and / or a voltage of the target charging pile is greater than or equal to a sixth threshold; and a remaining charge of the vehicle's battery after the vehicle arrives at the charging station is greater than a fifth threshold. If the first condition is met, the vehicle area control system controls the battery management system 110 shown in FIG. 1B to allow the temperature of the electric battery to be adjusted and to send a first message to the thermal management system 130. The first message may be a temperature adjustment request, and the request is used to request the thermal management system to adjust the temperature of the electric battery.

[0072] In the second case, the vehicle area control system sends a first message to the thermal management system.

[0073] Unlike the first case, before the vehicle arrives at the charging station, after the vehicle area control system 120 shown in FIG. 1B determines that the first condition is met, the vehicle area control system 120 authorizes the temperature of the electric battery to be adjusted and sends a first message to the thermal management system 130. The first message may be instruction information, which instructs the thermal management system to adjust the temperature of the electric battery 111.

[0074] In a third case, another device sends a first message to the thermal management system.

[0075] Unlike the first case, a separate device replaces the vehicle area control system. Specifically, before the vehicle arrives at the charging station, the separate device obtains information such as the distance between the vehicle and the charging station, the estimated time the vehicle will arrive at the charging station, the power of each charging pile and each charging pile within the charging station, the current of the charging pile within the charging station, the voltage of the charging pile within the charging station, and the state of charge of the vehicle's battery after the vehicle arrives at the charging station. Based on the information, the separate device determines whether a first condition is met. The first condition includes at least one of the following: the distance between the vehicle and the charging station is less than or equal to a first threshold, and / or the estimated time the vehicle will arrive at the charging station is less than or equal to a second threshold, the power of a target charging pile within the charging station is greater than a third threshold, and / or the current of the target charging pile is greater than or equal to a fourth threshold, and / or the voltage of the target charging pile is greater than or equal to a sixth threshold, and the remaining charge of the vehicle's battery after the vehicle arrives at the charging station is greater than a fifth threshold. If a first condition is met, the other device authorizes the temperature of the electric battery to be adjusted and sends a first message to the thermal management system, the first message may be instruction information, and the instruction information instructs the thermal management system to adjust the temperature of the electric battery.

[0076] In a second application scenario, the electronic device is a vehicle or vehicle area control system.

[0077] In the following, an example in which the electronic device is a vehicle area control system is used for explanation.

[0078] For example, before a vehicle arrives at a charging station, the vehicle area control system 120 shown in FIG. 1B receives a first message. The first message instructs the temperature of the vehicle's battery to be adjusted to a target temperature when the vehicle arrives at the charging station. The target temperature is 25°C to 40°C. Based on the first message, the vehicle area control system 120 controls the thermal management system 130 to adjust the temperature of the vehicle's battery 111 to the target temperature when the vehicle arrives at the charging station.

[0079] The first message may be sent to the vehicle area control system by another device (i.e., a device other than the new energy vehicle, such as a mobile phone or a server). The first message may be of an instruction type or a content type. The instruction type may be understood as a type of instruction, command, etc. For example, the first message may be instruction information, a request, etc. The content type may be understood as a type of content, etc. For example, the first message may be vehicle information, charging station information, etc.

[0080] The various message types are described in detail below.

[0081] In the first case, the first message is of content type .

[0082] Before the vehicle arrives at the charging station, the vehicle area control system 120 shown in FIG. 1B receives a first message. The first message may include information such as the distance between the vehicle and the charging station, the estimated time the vehicle will arrive at the charging station, the power of each charging pile and each charging pile within the charging station, the current of the charging pile within the charging station, the voltage of the charging pile within the charging station, and the state of charge of the vehicle's battery after the vehicle arrives at the charging station. Based on the information, the vehicle area control system determines whether a first condition is met. The first condition includes at least one of the following: the distance between the vehicle and the charging station is less than or equal to a first threshold, and / or the estimated time the vehicle will arrive at the charging station is less than or equal to a second threshold, the power of a target charging pile within the charging station is greater than a third threshold, and / or the current of the target charging pile is greater than or equal to a fourth threshold, and / or the voltage of the target charging pile is greater than or equal to a sixth threshold, and the remaining charge of the vehicle's battery after the vehicle arrives at the charging station is greater than a fifth threshold. If the first condition is met, the vehicle region control system authorizes regulating the temperature of the electric battery and instructs the thermal management system to regulate the temperature of the electric battery.

[0083] In the second case, the first message is of the instruction type.

[0084] 1B receives a first message before the vehicle arrives at the charging station, the vehicle area control system 120 permits the temperature of the electric battery 111 to be adjusted based on the first message, and instructs the thermal management system 130 to adjust the temperature of the electric battery 111.

[0085] In another embodiment, the adjustment method provided in the embodiment of the present application may be applied to a communication system including two electronic devices. FIG. 2 is a diagram of the configuration of the communication system. As shown in FIG. 2, the system 200 may further include a first electronic device 210 and a second electronic device 220. The first electronic device 210 can send a first message to the second electronic device 220. The first message may be the associated message described above. The second electronic device 220 receives the first message and adjusts the temperature of the vehicle's battery based on the first message so that the temperature of the vehicle's battery is adjusted to a target temperature when the vehicle arrives at the charging station.

[0086] The first electronic device 210 may be a device with a display function, such as a server, a mobile phone, a tablet computer, a desktop computer, a laptop computer, a notebook computer, an ultra-mobile personal computer (UMPC), a handheld computer, a netbook, a personal digital assistant (PDA), a wearable electronic device, a television, or a virtual reality device. The specific form of the electronic device is not particularly limited in the embodiments of the present application.

[0087] The second electronic device 220 may include various product forms in the vehicle field, such as thermal management systems, on-board chips, and on-board devices (e.g., on-board infotainment systems, on-board computing platforms (e.g., vehicle area control systems), vehicles, and servers (virtual or physical)).

[0088] The following describes in detail various scenarios in which the adjustment method provided in the embodiments of the present application is applied.

[0089] In a first embodiment, the adjustment method provided in this embodiment of the present application is applied to an electronic device, which may be a thermal management system 130 shown in FIG. 1B, a vehicle area control system 120 shown in FIG. 1B, or a new energy vehicle 100 (vehicle for short) shown in FIG. 1B.

[0090] 3 is a schematic flowchart of an adjustment method 300 according to an embodiment of the present application. The method 300 may be performed by the thermal management system 130 shown in FIG. 1B, or by the vehicle area control system 120 shown in FIG. 1B, or by the new energy vehicle 100 shown in FIG. 1B. In the following, an example in which the method is performed by the vehicle area control system is used for description. The method 300 may include S301 and S302.

[0091] S301: An electronic device receives a first message, which instructs adjusting the temperature of a battery of a vehicle to a target temperature.

[0092] Specifically, before the vehicle arrives at the charging station, the electronic device receives a first message instructing the electronic device to adjust the temperature of the vehicle's battery to a target temperature when the vehicle arrives at the charging station.

[0093] The target temperature may be the temperature of the battery at which the battery will be charged at the fastest rate. The target temperature may be a specific value or a range of values. For example, the target temperature may be between 25°C and 40°C.

[0094] The following describes the first message in detail and individually from various aspects.

[0095] First aspect: First message type

[0096] The first message may be an instruction message, in which case the first message may directly instruct the vehicle to adjust the temperature of the battery of the vehicle to a target temperature when the vehicle arrives at the charging station.

[0097] The first message may instead be a content message. In this case, the first message may indirectly instruct the vehicle to adjust the temperature of the vehicle's battery to a target temperature when the vehicle arrives at the charging station. For example, the first message may include information such as the distance between the vehicle and the charging station, the estimated time the vehicle will arrive at the charging station, the power of each charging pile in the charging station, the current of the charging pile in the charging station, the voltage of the charging pile in the charging station, and the state of charge of the vehicle's battery after the vehicle arrives at the charging station.

[0098] Second aspect: First message generation opportunity

[0099] The opportunity to generate the first message varies depending on the message type, and is specifically as follows:

[0100] If the first message is a content message, the first message is generated when a user sets navigation to a charging station for the vehicle or when a route set by the user for the vehicle includes a charging station.

[0101] If the first message is an instruction message, the first message is generated when the vehicle and / or the charging station satisfy a first condition before the vehicle arrives at the charging station. The first condition may include at least one of the following: the distance between the vehicle and the charging station is less than or equal to a first threshold, and / or the estimated time for the vehicle to arrive at the charging station is less than or equal to a second threshold, the power of a target charging pile in the charging station is greater than a third threshold, and / or the current of the target charging pile is greater than or equal to a fourth threshold, and / or the voltage of the target charging pile is greater than or equal to a sixth threshold, and the remaining charge of the vehicle's battery after the vehicle arrives at the charging station is greater than a fifth threshold. The first, second, third, fourth, fifth, and sixth thresholds may be set based on actual conditions, which are not specifically limited herein.

[0102] S302: An electronic device adjusts the temperature of the battery of the vehicle based on the first message so as to adjust the temperature of the battery of the vehicle to a target temperature when the vehicle arrives at the charging station.

[0103] In one specific implementation, the electronic device checks the temperature of the battery. The electronic device compares the temperature of the battery with a target temperature. If the temperature of the battery is not equal to the target temperature, the electronic device adjusts the temperature of the vehicle's battery based on the first message.

[0104] In the embodiment of the present application, the temperature of the battery is adjusted before the vehicle arrives at the charging station, so that the temperature of the battery reaches the target temperature when the vehicle arrives at the charging station. In this way, the time for adjusting the temperature of the battery is effectively shortened, and the vehicle can be charged at the best charging rate when it arrives at the charging station, which effectively increases the charging rate of the battery and therefore improves the user's charging experience.

[0105] In some embodiments, to ensure a charging speed and reduce the operating energy consumption of the thermal management system, S302 may be specifically implemented as follows: an electronic device adjusts the temperature of the vehicle's battery based on a temperature control level, which is determined based on the available power of the charging pile and the state of charge (SOC) of the vehicle's battery at a first time point, which may be a point in time during the vehicle's journey to the charging station.

[0106] Assume that a charging station includes charging pile 1, charging pile 2, ..., and charging pile n. The powers of these charging piles range from several kW to hundreds of kW. Therefore, different levels of thermal management may be required based on the target pile power. When the target pile power is low, it is not necessary to heat the vehicle's battery to an excessively high temperature, e.g., 5°C, at low temperatures, so that the vehicle can be charged at the pile's maximum charging power. When the target pile power is high, it is necessary to heat the vehicle's battery to a high temperature, e.g., 20°C to 25°C, so that the vehicle can be charged at the pile's maximum charging power. Assume that the power of charging pile 1 (Power1) < the power of charging pile 2 (Power2) < ... < the power of charging pile n (Power n), and SOC1 > SOC2 > ... > SOC n.

[0107] Therefore, we obtain the temperature control level distribution table shown in Table 1. This table represents different temperature control levels corresponding to the SOC of different batteries in different charging piles.

[0108] [Table 1]

[0109] It can be seen from Table 1 that when a vehicle arrives at a charging station and the pile power of the charging station is low and the remaining SOC of the vehicle is high, for example, at pile Power1 and SOC1, a temperature control level of Level 11 is requested and the electronic device adjusts the temperature based on the Level 11 level, so the temperature is adjusted and controlled at a low level to the target temperature. When a vehicle arrives at a charging station and the pile power of the charging station is high and the remaining SOC of the vehicle is low, for example, at pile Power n and SOC m, a temperature control level of Level mn is requested and the electronic device adjusts the temperature based on the Level mn level, so the temperature is adjusted and controlled at a high level to the target temperature.

[0110] In this embodiment of the present application, different levels of temperature regulation are implemented based on the power of different charging piles, thus reducing the operating energy consumption of the thermal management system while ensuring the best charging speed.

[0111] In a second embodiment, the adjustment method provided in this embodiment of the present application is applied to a new energy vehicle (vehicle for short) shown in Figure 1B. The vehicle may include a map application program (map application for short), a battery management system, a thermal management system, and a vehicle area control system.

[0112] 4A-1 and 4A-2 and 4B-1 and 4B-2 are schematic flowcharts of an adjustment method according to an embodiment of the present application. Method 400 is an extension of method 300. For example, the steps performed by the vehicle in method 400 may be performed by the electronic device shown in FIG. 3. It should be understood that the steps or operations of the adjustment method shown in FIGS. 4A-1 and 4A-2 and 4B-1 and 4B-2 are merely examples. In an embodiment of the present application, other operations or variations of the operations in FIGS. 4A-1 and 4A-2 and 4B-1 and 4B-2 may also be performed. In addition, the steps of Figures 4A-1 and 4A-2 and Figures 4B-1 and 4B-2 may be performed in an order different from that presented in Figures 4A-1 and 4A-2 and Figures 4B-1 and 4B-2, and not all of the operations in Figures 4A-1 and 4A-2 and Figures 4B-1 and 4B-2 need to be performed.

[0113] As shown in FIGS. 4A-1 and 4A-2 and 4B-1 and 4B-2, the method 400 may include steps S401 to S410.

[0114] S401: A map application of a vehicle displays a first interface, and a location of the vehicle, at least one charging station, and an operation status of the at least one charging station are displayed on the first interface.

[0115] The operating state of the charging station may be understood as the state of each charging pile in the charging station, for example, the charging pile in the charging station is in an in-use state, or the charging pile in the charging station is in an unused state.

[0116] S402: A map application of the vehicle receives a first user operation on a first interface, the first operation being an operation in which the user configures the map application to proceed to or pass by a charging station.

[0117] The first action may include a user configuring a map application to navigate to a charging station or to drive by a charging station.

[0118] S403: In response to the first operation, the map application of the vehicle sends first information to the vehicle area control system of the vehicle, the first information representing information about the vehicle and / or the charging station, and the vehicle area control system of the vehicle receives the first information accordingly.

[0119] The first information may include at least one of the following: a distance between the vehicle and the charging station, an estimated time for the vehicle to arrive at the charging station, a type of each charging pile in the charging station, a power of each charging pile in the charging station, a rated current of each charging pile in the charging station, and a maximum voltage and a minimum voltage of each charging pile in the charging station.

[0120] S404: A vehicle region control system of the vehicle receives second information transmitted by a battery of the battery management system, where the second information includes a state of charge and a temperature of the battery.

[0121] S405: A vehicle region control system of the vehicle generates a first message based on the first information and the second information, where the first message instructs adjusting the temperature of the battery of the vehicle to a target temperature.

[0122] Adjusting the temperature of the vehicle battery to a target temperature may be understood as follows: the electrochemical cells of the vehicle battery are heated so that the temperature rises to the target temperature. For example, if the target temperature is 25°C to 40°C and the battery temperature is 10°C, the electrochemical cells of the vehicle battery are heated. Alternatively, the electrochemical cells of the vehicle battery are cooled so that the temperature falls to the target temperature. For example, if the target temperature is 25°C to 40°C and the battery temperature is 50°C, the electrochemical cells of the vehicle battery are cooled.

[0123] In a specific implementation, the vehicle's vehicle area control system determines the remaining charge of the battery when the vehicle arrives at the charging station based on the battery's state of charge, the vehicle's energy consumption information under various road conditions and various vehicle speeds, and the user's driving habit information. The vehicle's vehicle area control system determines whether the vehicle and / or the charging station meets a first condition based on the remaining charge of the battery when the vehicle arrives at the charging station, the distance between the vehicle and the charging station, the estimated time the vehicle will arrive at the charging station, the type of each charging pile in the charging station, the power of each charging pile in the charging station, the rated current of each charging pile in the charging station, and the maximum and minimum voltages of each charging pile in the charging station. The first condition may include at least one of the following: the distance between the vehicle and the charging station is less than or equal to a first threshold, and / or the estimated time for the vehicle to arrive at the charging station is less than or equal to a second threshold, the power of a target charging pile in the charging station is greater than a third threshold, and / or the current of the target charging pile is greater than or equal to a fourth threshold, and / or the voltage of the target charging pile is greater than or equal to a sixth threshold, and the remaining charge of the vehicle's battery after the vehicle arrives at the charging station is greater than a fifth threshold. If the first condition is met, the vehicle generates the first message. If the first condition is not met, the vehicle does not generate the first message.

[0124] S406: A vehicle region control system of the vehicle sends a first message to the battery management system, and the battery management system receives the first message accordingly.

[0125] S407: The battery management system sends a first request to the thermal management system based on the first message and the temperature of the battery, the first request is used to request the thermal management component to adjust the temperature of the vehicle's battery, and the thermal management system receives the first request accordingly.

[0126] In one specific implementation, after the battery management system receives the first message, the battery management system determines whether the temperature of the battery is equal to the target temperature. If the battery management system determines that the temperature of the battery is not equal to the target temperature, the battery management system sends a first request to the thermal management system.

[0127] S408: The thermal management system adjusts the temperature of the battery based on the first request.

[0128] In a specific implementation, S406 to S408 may be modified as follows: A vehicle area control system of the vehicle sends a first message to a thermal management system of the vehicle, and the thermal management system is configured to adjust the temperature of a battery of the vehicle based on the first message.

[0129] S409: The vehicle's battery management system feeds back a second message to the map application, the second message carrying the ongoing temperature adjustment status, and the map application receives the second message accordingly.

[0130] The on-going temperature regulation state indicates that the vehicle is in a battery heating state while proceeding to the charging station. For example, the on-going temperature regulation state may include an on-going heating state and an on-going cooling state.

[0131] S410: Further display the vehicle's ongoing temperature control status on the first interface displayed by the map application.

[0132] As described above, the ongoing temperature adjustment state may include an ongoing heating state and an ongoing cooling state. For example, the ongoing temperature adjustment state is an ongoing heating state. During the process of pre-heating the electric battery, the ongoing heating state may be displayed on the first interface in a text format, such as "Smart Pre-heat!". Once the pre-heating of the electric battery is completed, the ongoing heating state may be displayed on the first interface as "Smart Pre-heat Completed."

[0133] In the embodiment of the present application, the temperature of the battery is adjusted before the vehicle arrives at the charging station, so that the temperature of the battery reaches the target temperature when the vehicle arrives at the charging station. In this way, the time for adjusting the temperature of the battery is effectively shortened, and the vehicle can be charged at the best charging rate when it arrives at the charging station, which effectively increases the charging rate of the battery and therefore improves the user's charging experience.

[0134] In some embodiments, to reduce the operating energy consumption of the thermal management system while ensuring the charging rate, S405 may specifically be S4051: the vehicle area control system of the vehicle determines the power of available charging piles in the charging station and the state of charge of the vehicle's battery at a first time point. S406 may specifically be S4061: the vehicle area control system of the vehicle sends a first message to the battery management system based on the power of available charging piles and the state of charge of the vehicle's battery at the first time point, where the first message is further used to request a temperature control level. S407 may specifically be S4071: the battery management system sends a first request to the thermal management system based on the first message and the temperature of the battery, where the first request carries the temperature control level. S408 may specifically be S4081: the thermal management system adjusts the temperature of the battery based on the first request.

[0135] In another specific implementation, as shown in FIGS. 4B-1 and 4B-2, S4061 to S4081 may be as follows: A vehicle area control system of a vehicle determines a temperature control level based on the power of an available charging pile and the state of charge of a battery of the vehicle at a first time point; The vehicle area control system of the vehicle sends a first message to a battery management system, where the first message carries the temperature control level; The battery management system sends a first request to a thermal management system based on the first message and the temperature of the battery, where the first request carries the temperature control level; The thermal management system adjusts the temperature of the battery based on the first request.

[0136] In this embodiment of the present application, different temperature control levels of temperature regulation are implemented based on the power of different charging piles and the charging state of the battery. The temperature control level can be flexibly adjusted based on the available charging piles and the charging state of the battery. In this way, the operating energy consumption of the thermal management system is reduced while ensuring the best charging speed.

[0137] In a third embodiment, the coordination method provided in this embodiment of the present application is applied to the communication system shown in Figure 2. The communication system may include a first electronic device and a second electronic device. The first electronic device may include a map application program (abbreviated as map application), and the second electronic device may include a battery management system, a thermal management system, and a vehicle area control system. For example, the first electronic device is a mobile phone, and the second electronic device is a vehicle.

[0138] 5A and 5B are schematic flowcharts of an adjustment method according to an embodiment of the present application. Method 500 is an extension of method 300. For example, the steps performed by the vehicle and / or the mobile phone in method 500 may be performed by the electronic device shown in FIG. 3. It should be understood that the adjustment method steps or operations shown in FIGS. 5A and 5B are merely examples. In embodiments of the present application, other operations or variations of the operations in FIGS. 5A and 5B may also be performed. In addition, the steps in FIGS. 5A and 5B may be performed in a different order than presented in FIGS. 5A and 5B, and not all operations in FIGS. 5A and 5B need to be performed.

[0149] S506: A vehicle region control system of the vehicle generates a first message based on the first information and the second information, the first message instructing the temperature of the vehicle's battery to be adjusted to a target temperature when the vehicle arrives at the charging station.

[0150] S507: The vehicle region control system of the vehicle sends a first message to the battery management system, and the battery management system receives the first message accordingly.

In this way, the time for adjusting the temperature of the battery is effectively shortened, and the vehicle can be charged at the best charging rate when it arrives at the charging station, which effectively increases the charging rate of the battery and therefore improves the user's charging experience.
