Description

Adjustment method, electronic device and communication system Technical Field

[0001] The embodiments of the present application relate to the field of new energy technologies, and in particular to an adjustment method, an electronic device, and a communication system. Background Art

[0002] With the development of new energy vehicles, there's a need to increase their charging speeds to enhance the user experience and product competitiveness. However, the charging speed of new energy vehicles depends on the battery's charging speed, which varies at different temperatures. Adjusting battery temperature to increase charging speed remains a challenge for those skilled in the art.

[0003] Summary of the Invention

[0004] The embodiments of the present application provide an adjustment method, an electronic device, and a communication system that shorten the charging time of a vehicle, increase the charging rate of the battery, and provide users with a better charging experience.

[0005] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions.

[0006] In a first aspect, an embodiment of the present application provides an adjustment method. The execution subject of the method can be an electronic device or a component located in the electronic device (for example, a chip, a chip system, or a processor, etc.). The following description takes the execution subject being an electronic device as an example. The method includes: the electronic device receives a first message, and the first message is used to instruct to adjust 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 so that the temperature of the vehicle's battery is adjusted to the target temperature when the vehicle arrives at the charging station.

[0007] The target temperature may be the temperature of the battery when the battery is charged at the fastest rate. The target temperature may be a specific value or a numerical range. For example, the target temperature may be 25°C to 40°C.

[0008] The first message may be an instruction message. For example, the first message may be instruction information or request information. The first message may also be a content message. For example, the first message may include vehicle information and / or charging station information.

[0009] This allows the battery temperature to be adjusted before the vehicle arrives at the charging station, saving time. By the time the vehicle arrives at the charging station, the battery temperature has already been adjusted to the target temperature, allowing the vehicle to charge at a faster rate. Overall, this shortens the vehicle's charging time, increases the battery's charging rate, and provides users with a better charging experience.

[0010] In a specific implementation manner, the first message is generated before the vehicle arrives at the charging station and when the first condition is met.

[0011] In a 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 reach the charging station is less than or equal to a second threshold; the power of the 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; after the vehicle reaches the charging station, the remaining state of charge of the vehicle's battery is greater than a fifth threshold.

[0012] In a specific implementation, the electronic device adjusts the temperature of the battery of the vehicle according to the first message. Specifically, when the temperature of the battery is not equal to the target temperature, the electronic device adjusts the temperature of the battery of the vehicle according to the first message.

[0013] In a specific implementation method, the electronic device adjusts the temperature of the vehicle's battery. Specifically, the electronic device adjusts the temperature of the vehicle's battery according to a temperature control level, and the temperature control level is determined based on the power of the available charging pile at the first moment and the charge state of the vehicle's battery.

[0014] The embodiment of the present application realizes different levels of temperature adjustment according to the power of different charging piles, thereby saving the working energy consumption of the thermal management system while ensuring the optimal charging rate.

[0015] On the second aspect, an embodiment of the present application provides an adjustment method, the execution subject of the method may be an electronic device, or a component located in the electronic device (for example, a chip, a chip system or a processor, etc.), and the following description will be made using the execution subject being an electronic device as an example. The method may include: the electronic device receives first information sent by a map application, the first information being used to characterize information about the vehicle and / or charging station. The electronic device receives second information sent by a battery management system, the second information including the state of charge and temperature of the battery. The electronic device generates a first message based on the first information and the second information, the first message being used to instruct that the temperature of the vehicle's battery be adjusted to a target temperature. The electronic device adjusts the temperature of the vehicle's battery based on the first message, so that when the vehicle arrives at the charging station, the temperature of the vehicle's battery is adjusted to the target temperature.

[0016] This allows the battery temperature to be adjusted before the vehicle arrives at the charging station, saving time. By the time the vehicle arrives at the charging station, the battery temperature has already been adjusted to the target temperature, allowing the vehicle to charge at a faster rate. Overall, this shortens the vehicle's charging time, increases the battery's charging rate, and provides users with a better charging experience.

[0017] In a specific implementation, the electronic device adjusts the temperature of the vehicle's battery according to the first message. Specifically, the electronic device sends the first message to the thermal management system, and the thermal management system is used to adjust the temperature of the vehicle's battery according to the first message.

[0018] In a specific implementation method, the electronic device adjusts the temperature of the vehicle's battery based on the first message. Specifically, the electronic device sends the first message to the battery management system, and the battery management system is used to send 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 system to adjust the temperature of the vehicle's battery.

[0019] In a specific implementation manner, the first message is generated before the vehicle arrives at the charging station and when the first condition is met.

[0021] In a specific implementation, the electronic device adjusts the temperature of the battery of the vehicle according to the first message. Specifically, when it is determined that the battery temperature is not equal to the target temperature, the electronic device adjusts the temperature of the battery of the vehicle according to the first message.

[0022] In one specific implementation, the electronic device adjusts the temperature of the vehicle's battery based on the first message. Specifically, the electronic device may determine, at a first moment, the power of available charging piles at a charging station and the state of charge of the vehicle's battery. The electronic device determines a temperature control level based on the power of the available charging piles and the state of charge of the vehicle's battery at the first moment. The electronic device adjusts the temperature of the vehicle's battery based on the temperature control level.

[0071] The charging rate of new energy vehicles depends on the battery's charge rate, which in turn is related to the battery's temperature. Generally, the battery charges faster when the temperature is between 25°C and 40°C. For example, at a normal temperature of 25°C, it takes A minutes to charge to 50% capacity. At a low temperature of -10°C, it takes 6*A minutes to charge to 50%. Therefore, how can we adjust the battery temperature to improve the battery's charge rate?

[0072] In order to adjust the temperature of the battery, in one scenario, FIG1A is a functional block diagram of a new energy vehicle 100. 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 used to adjust the temperature of the battery cells. The vehicle domain control system 120 is used to control the thermal management system to adjust the temperature of the battery cells of the battery 111 in the battery management system 110.

[0073] Specifically, when a new energy vehicle is charging, the battery management system or vehicle-wide control system recognizes that the vehicle is charging and the battery temperature is less than 25°C. At this point, the vehicle-wide control system controls the thermal management system to adjust the temperature of the battery cells in the battery management system to between 25°C and 40°C. However, since adjusting the battery temperature takes time, adjusting the battery temperature during the charging process will result in the battery charging while the battery cells are being adjusted in temperature, which still results in a low battery charging rate.

[0074] In order to improve the charging rate of the battery, an embodiment of the present application provides an adjustment method, which includes receiving a first message, where the first message is used to instruct the temperature of the vehicle's battery to be adjusted to a target temperature. According to the first message, the temperature of the vehicle's battery is adjusted so that when the vehicle arrives at the charging station, the temperature of the vehicle's battery is adjusted to the target temperature. In this way, the temperature of the battery is adjusted before the vehicle arrives at the charging station, saving the time for temperature adjustment; 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 reach a faster charging rate for charging when it arrives at the charging station. Overall, the charging time of the vehicle is shortened, the charging rate of the battery is improved, and the user has a better charging experience.

[0075] Figure 1B is a functional block diagram of another new energy vehicle 100 provided in an embodiment of the present application. The new energy vehicle 100 may include the functional modules shown in Figure 1A. At the same time, the new energy vehicle 100 may also include a map application 140. The map application 140 is used to provide vehicle information and / or charging station information to the vehicle domain control system 120. In one embodiment, the adjustment method provided in an embodiment of the present application can be applied to an electronic device, which may include different product forms in the automotive field, such as: a thermal management system, a vehicle domain control system, an on-board chip, and an on-board device (such as: a car computer, an on-board computing platform, a whole vehicle, a server (virtual or physical)). The following is a detailed introduction to different application scenarios:

[0076] The first application scenario is that the electronic device is a thermal management system.

[0077] For example, before the vehicle arrives at the charging station, the thermal management system 130 shown in FIG1B receives a first message instructing 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 vehicle's battery temperature based on the first message so that the vehicle's battery temperature reaches the target temperature when the vehicle arrives at the charging station.

[0078] The first message may be sent from the battery management system 110 of the new energy vehicle 100 shown in FIG1B to the thermal management system 130, or from the vehicle domain control system 120 of the new energy vehicle 100 shown in FIG1B to the thermal management system 130, or from other devices (i.e., devices outside the new energy vehicle, such as a mobile phone or server) to the thermal management system. Detailed description is given below:

[0079] In the first scenario, the battery management system sends a first message to the thermal management system.

[0080] Before the vehicle arrives at the charging station, the vehicle domain control system 120 shown in FIG1B obtains information such as the distance between the vehicle and the charging station, the estimated time it will take for the vehicle to reach the charging station, the charging piles in the charging station and their power, the current of the charging piles in the charging station, the voltage of the charging piles 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 FIG1B sends the above vehicle information and / or charging station information to the vehicle domain control system 120. Based on this information, the vehicle domain control system determines whether a first condition is met, which 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 it will take for the vehicle to reach the charging station is less than or equal to a second threshold; the power of the 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 state of 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 domain control system allows the temperature of the electric battery to be adjusted, and controls the battery management system 110 shown in Figure 1B to send a first message to the thermal management system 130. The first message can be a temperature adjustment request, which is used to request the thermal management system to adjust the temperature of the electric battery.

[0081] In the second scenario, the vehicle domain control system sends a first message to the thermal management system.

[0082] The difference compared to the first situation is that before the vehicle arrives at the charging station, after the vehicle domain control system 120 shown in Figure 1B determines that the first condition is met, the vehicle domain control system 120 allows the temperature of the electric battery to be adjusted and sends a first message to the thermal management system 130. The first message can be an indication information, which is used to instruct the thermal management system to adjust the temperature of the electric battery 111.

[0083] In the third scenario, other devices send a first message to the thermal management system.

[0084] The difference from the first scenario is that other devices replace the vehicle domain control system. Specifically, before the vehicle arrives at the charging station, the other devices obtain information such as the distance between the vehicle and the charging station, the estimated time for the vehicle to reach the charging station, the charging piles in the charging station and their power, the current of the charging piles in the charging station, the voltage of the charging piles in the charging station, and the state of charge of the vehicle's battery after the vehicle arrives at the charging station. The other devices determine whether the first condition is met based on the above information. 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 the first threshold, and / or the estimated time for the vehicle to reach the charging station is less than or equal to the second threshold; the power of the target charging pile in the charging station is greater than the third threshold; and / or the current of the target charging pile is greater than or equal to the fourth threshold; and / or the voltage of the target charging pile is greater than or equal to the sixth threshold; the remaining state of charge of the vehicle's battery after the vehicle arrives at the charging station is greater than the fifth threshold. If the first condition is met, the other devices allow the temperature of the electric battery to be adjusted and send a first message to the thermal management system. The first message can be an indication information, which is used to instruct the thermal management system to adjust the temperature of the electric battery.

[0085] The second application scenario is that the electronic device is a whole vehicle or a whole vehicle domain control system.

[0086] The following description assumes that the electronic device is the entire vehicle domain control system:

[0087] Exemplarily, before a vehicle arrives at a charging station, the vehicle domain control system 120 shown in FIG1B receives a first message instructing the vehicle's battery to be adjusted to a target temperature of 25° C. to 40° C. upon arrival at the charging station. Based on the first message, the vehicle domain control system 120 controls the thermal management system 130 to adjust the vehicle's battery temperature so that the temperature of the vehicle's battery 111 reaches the target temperature upon arrival at the charging station.

[0088] The first message may be sent by another device (i.e., a device other than a new energy vehicle, such as a mobile phone or a server) to the vehicle domain control system. The type of the first message may be an indication type or a content type. The indication type may be understood as an indication, a command, or the like. For example, the first message may be an indication message, a request, or the like. The content type may be understood as a content type. For example, the first message may be vehicle information and / or charging station information.

[0089] The following is a detailed introduction to different message types:

[0090] First, the type of the first message is the content type.

[0091] Before the vehicle arrives at the charging station, the vehicle domain control system 120 shown in FIG1B receives a first message. This first message may include information such as the distance between the vehicle and the charging station, the estimated time it will take for the vehicle to reach the charging station, the charging piles in the charging station and their power, the current of the charging piles in the charging station, the voltage of the charging piles in the charging station, and the state of charge of the vehicle's battery after the vehicle arrives at the charging station. Based on this information, the vehicle domain 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 it will take for the vehicle to reach the charging station is less than or equal to a second threshold; the power of the 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 state of 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 domain control system allows the electric battery temperature to be adjusted and instructs the thermal management system to adjust the electric battery temperature.

[0092] Second, the type of the first message is an indication type.

[0093] Before the vehicle arrives at the charging station, the vehicle domain control system 120 shown in FIG1B receives a first message. Based on the first message, the vehicle domain control system 120 allows the temperature of the electric battery 111 to be adjusted and instructs the thermal management system 130 to adjust the temperature of the electric battery 111.

[0094] In another embodiment, the adjustment method provided in the embodiment of the present application can be applied to a communication system composed of two electronic devices. Figure 2 is a schematic diagram of the structure of the communication system. As shown in Figure 2, the above-mentioned system 200 may also include a first electronic device 210 and a second electronic device 220. The first electronic device 210 may send a first message to the second electronic device 220, and the first message may be the related message described above. The second electronic device 220 receives the first message and adjusts the temperature of the vehicle's battery according to the first message so that the temperature of the vehicle's battery reaches the target temperature when the vehicle arrives at the charging station.

[0095] Among them, the above-mentioned first electronic device 210 can be a server, or a mobile phone, tablet computer, desktop, laptop, notebook computer, ultra-mobile personal computer (UMPC), handheld computer, netbook, personal digital assistant (PDA), wearable electronic device, television, virtual reality equipment and other devices with display function. The specific form of the electronic device is not particularly limited in the embodiments of the present application.

[0096] Among them, the above-mentioned second electronic device 220 may include different product forms in the automotive field, such as: thermal management system, vehicle-mounted chip, vehicle-mounted device (such as: vehicle computer, vehicle-mounted computing platform (such as vehicle domain control system), whole vehicle, server (virtual or physical)).

[0097] The following is a detailed introduction to different scenarios in which an adjustment method provided in an embodiment of the present application is applied:

[0098] In a first embodiment, an adjustment method provided in an embodiment of the present application is applied to an electronic device. The electronic device may be the thermal management system 130 shown in FIG1B , the vehicle domain control system 120 shown in FIG1B , or the new energy vehicle 100 (referred to as the vehicle) shown in FIG1B .

[0099] Figure 3 shows a flow chart of an adjustment method 300 provided in an embodiment of the present application. This method 300 can be executed by the thermal management system 130 shown in Figure 1B , or by the vehicle-domain control system 120 shown in Figure 1B , or by the new energy vehicle 100 shown in Figure 1B . The following description uses the vehicle-domain control system as an example. This method 300 may include: S301 and S302.

[0100] S301: An electronic device receives a first message, where the first message is used to instruct the temperature of a vehicle battery to be adjusted to a target temperature.

[0101] Specifically, before the vehicle arrives at the charging station, the electronic device receives a first message that instructs the temperature of the vehicle's battery to be adjusted to a target temperature when the vehicle arrives at the charging station.

[0102] The target temperature may be the temperature of the battery when the battery is charged at the fastest rate. The target temperature may be a specific value or a numerical range. For example, the target temperature may be 25°C to 40°C.

[0103] The following is a detailed introduction from different dimensions of the first message:

[0104] The first dimension is the type of the first message.

[0105] The first message may be an instruction message, and may be used to directly instruct the vehicle to adjust the battery temperature to a target temperature when the vehicle arrives at the charging station.

[0106] The first message can also be a content-based message. In this case, the first message can indirectly instruct the vehicle's battery to be adjusted to a target temperature upon arrival 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 it will take for the vehicle to reach the charging station, the charging piles in the charging station and their power ratings, the current drawn by the charging piles, the voltage drawn by the charging piles, and the state of charge of the vehicle's battery upon arrival.

[0107] The second dimension is the timing of the generation of the first message.

[0108] The timing of generating the first message varies depending on the message type. The details are as follows:

[0109] If the first message is a content-based message, the first message is generated when the user sets navigation for the vehicle to go to a charging station, or when the route set by the user for the vehicle includes a charging station.

[0110] If the first message is an indication message, the first message is generated before the vehicle arrives at the charging station and when the vehicle and / or the charging station meet the first condition. 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 the first threshold, and / or the estimated time for the vehicle to reach the charging station is less than or equal to the second threshold; the power of the target charging pile in the charging station is greater than the third threshold; and / or the current of the target charging pile is greater than or equal to the fourth threshold; and / or the voltage of the target charging pile is greater than or equal to the sixth threshold; after the vehicle arrives at the charging station, the remaining state of charge of the vehicle's battery is greater than the fifth threshold. The first threshold, the second threshold, the third threshold, the fourth threshold, the fifth threshold, and the sixth threshold can be set according to actual conditions and are not specifically limited here.

[0111] S302: The electronic device adjusts the temperature of the vehicle's battery according to 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.

[0112] In one specific implementation, the electronic device identifies a battery temperature, compares the battery temperature with a target temperature, and adjusts the battery temperature of the vehicle according to the first message when the battery temperature is not equal to the target temperature.

[0113] The present embodiment adjusts the battery temperature before the vehicle arrives at the charging station, ensuring that the battery reaches the target temperature upon arrival. This effectively reduces the time required to adjust the battery temperature, allowing the vehicle to charge at the optimal rate upon arrival, effectively improving the battery's charging rate and providing users with a better charging experience.

[0114] In some embodiments, to ensure charging speed while conserving energy consumption of the thermal management system, S302 may be specifically implemented as follows: the electronic device adjusts the temperature of the vehicle's battery according to a temperature control level. The temperature control level is determined based on the available charging station power and the state of charge (SOC) of the vehicle's battery at a first moment. The first moment may refer to a moment while the vehicle is traveling to the charging station.

[0115] Assume that a charging station includes charging pile 1, charging pile 2, and charging pile n. The power of these charging piles ranges from a few kW to several hundred kW. Therefore, different levels of thermal management can be requested based on the power of the target pile. If the target pile power is low, the vehicle battery temperature does not need to be heated too high at low temperatures. For example, heating it to 5°C allows the vehicle to charge at the pile's maximum charging power. If the target pile power is high, the temperature needs to be heated to a higher temperature, such as 20-25°C, to allow the vehicle to charge at the pile's maximum charging power. Assume: the power of charging pile 1 (Power1) is less than the power of charging pile 2 (Power2) and less than the power of charging pile n (Powern), and SOC1>SOC2>..>SOCn.

[0116] Therefore, a temperature control level distribution table as shown in Table 1 is obtained, which shows different temperature control levels corresponding to the SOCs of different batteries in different charging piles.

[0117] Table 1

[0118]

[0119] Table 1 shows that if the charging station's power is low and the vehicle's remaining SOC is high when the vehicle arrives at the charging station, for example, when the charging station's Power is 1 and the vehicle's remaining SOC is high, then Level 11 temperature control is requested. The electronic device adjusts the temperature based on Level 11, bringing the target temperature to a lower level. If the charging station's power is high and the vehicle's remaining SOC is low when the vehicle arrives at the charging station, for example, when the charging station's Power is n and the vehicle's remaining SOC is low, then Level mn temperature control is requested. The electronic device adjusts the temperature based on Level mn, bringing the target temperature to a higher level.

[0120] The embodiment of the present application realizes different levels of temperature adjustment according to the power of different charging piles, thereby saving the working energy consumption of the thermal management system while ensuring the optimal charging rate.

[0121] In a second embodiment, an adjustment method provided in an embodiment of the present application is applied to the new energy vehicle (hereinafter referred to as the vehicle) shown in FIG1B . The vehicle may include a map application (hereinafter referred to as the map application), a battery management system, a thermal management system, and a vehicle domain control system.

[0122] Figures 4A and 4B are flow charts of an adjustment method provided in an embodiment of the present application. Method 400 is an extension of method 300. Exemplarily, the steps performed by the vehicle in method 400 can be performed by the electronic device shown in Figure 3. It should be understood that the steps or operations of the adjustment method shown in Figures 4A and 4B are merely examples, and the embodiment of the present application can also perform other operations or variations of the various operations in Figures 4A and 4B. In addition, the various steps in Figures 4A and 4B can be performed in a different order than that presented in Figures 4A and 4B, and it may not be necessary to perform all the operations in Figures 4A and 4B.

[0123] As shown in FIG. 4A and FIG. 4B , the method 400 may include: S401 - S410 .

[0124] S401. A map application of a vehicle displays a first interface, where the first interface displays the location of the vehicle, at least one charging station, and the operating status of at least one charging station.

[0125] The working state of the charging station can be understood as the state of each charging pile in the charging station, for example, the charging pile in the charging station is in a used state, or the charging pile in the charging station is in a non-used state.

[0126] S402: The map application of the vehicle receives a first operation of the user on a first interface, where the first operation is an operation of the user setting navigation to a charging station or passing through a charging station on the map application.

[0127] The first operation may include an operation of the user setting a navigation to the charging station on the map application, or an operation of the user setting a route to the charging station on the map application.

[0128] S403: In response to the first operation, the vehicle's map application sends first information to the vehicle's domain control system, where the first information is used to represent information about the vehicle and / or charging station. Accordingly, the vehicle's domain control system receives the first information.

[0129] The first information may include at least one of the following: the distance between the vehicle and the charging station, the estimated time for the vehicle to reach 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 voltage and minimum voltage of each charging pile in the charging station.

[0130] S404. The vehicle domain control system of the vehicle receives second information sent by the battery of the battery management system, where the second information includes the state of charge and temperature of the battery.

[0131] S405. The vehicle domain control system generates a first message based on the first information and the second information. The first message is used to instruct to adjust the temperature of the battery of the vehicle to a target temperature.

[0132] Among them, adjusting the temperature of the vehicle's battery to the target temperature can be understood as: heating the battery cells of the vehicle's battery so that the temperature increases to the target temperature. For example, assuming that the target temperature is 25°C to 40°C and the battery temperature is 10°C, the battery cells of the vehicle's battery are heated; or, cooling the battery cells of the vehicle's battery so that the temperature drops to the target temperature. For example, assuming that the target temperature is 25°C to 40°C and the battery temperature is 50°C, the battery cells of the vehicle are cooled.

[0133] In one specific implementation, a vehicle's vehicle-wide control system determines the remaining state of charge (SOC) of the battery upon arrival at the charging station based on the battery's SOC, energy consumption information for the vehicle under different road conditions and at different speeds, and information about the user's driving habits. The vehicle-wide control system determines whether the vehicle and / or charging station meet a first condition based on the battery's SOC upon arrival, the distance between the vehicle and the charging station, the estimated time it will take for the vehicle to reach the charging station, the type of charging piles 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 it will take for the vehicle to reach the charging station is less than or equal to a second threshold; the power of the 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 after the vehicle arrives at the charging station, the remaining SOC of the battery of the vehicle is greater than a fifth threshold. If the first condition is met, the vehicle generates a first message; if the first condition is not met, the vehicle does not generate the first message.

[0134] S406. The vehicle domain control system sends the first message to the battery management system. Correspondingly, the battery management system receives the first message.

[0135] 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, wherein the first request is used to request the thermal management component to adjust the temperature of the battery of the vehicle.

[0136] In one specific implementation, after receiving the first message, the battery management system determines whether the battery temperature is equal to the target temperature. If the battery management system determines that the battery temperature is not equal to the target temperature, the battery management system sends a first request to the thermal management system.

[0137] S408 : The thermal management system adjusts the temperature of the battery according to the first request.

[0138] In a specific implementation, S406-S408 may be modified as follows: the vehicle domain control system sends the first message to the vehicle thermal management system, which is configured to adjust the temperature of the vehicle battery according to the first message.

[0139] S409: The vehicle's battery management system feeds back a second message to the map application, where the second message carries the navigation temperature adjustment status. Accordingly, the map application receives the second message.

[0140] The navigation temperature adjustment state is used to indicate that the vehicle is in a battery heating state during the process of navigating to a charging station. For example, the navigation temperature adjustment state may include a navigation heating state and a navigation cooling state.

[0141] S410: The first interface displayed by the map application also displays the navigation temperature adjustment status of the vehicle.

[0142] As mentioned above, the navigation temperature adjustment state can include a navigation heating state and a navigation cooling state. For example, when the navigation temperature adjustment state is the navigation heating state, the navigation heating state may be displayed on the first interface in text form, such as "Intelligent Preheating!", during the preheating of the electric battery. When the preheating of the electric battery is complete, the navigation heating state may be displayed on the first interface in text form, such as "Intelligent Preheating Completed."

[0143] The present embodiment adjusts the battery temperature before the vehicle arrives at the charging station, ensuring that the battery reaches the target temperature upon arrival. This effectively reduces the time required to adjust the battery temperature, allowing the vehicle to charge at the optimal rate upon arrival, effectively improving the battery's charging rate and providing users with a better charging experience.

[0144] In some embodiments, in order to save the working energy consumption of the thermal management system while ensuring the charging rate. S405 can be specifically as follows: S4051. The vehicle's whole vehicle domain control system determines the power of the available charging piles in the charging station and the state of charge of the vehicle's battery at the first moment. S406 can be specifically as follows: S4061. The vehicle's whole vehicle domain control system sends a first message to the battery management system based on the power of the available charging piles and the state of charge of the vehicle's battery at the first moment. The first message is also used to request a temperature control level. S407 can be specifically as follows: 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. The first request carries the temperature control level. S408 can be specifically as follows: S4081. The thermal management system adjusts the temperature of the battery according to the first request.

[0145] In another specific implementation, as shown in FIG4B , S4061-S4081 may be as follows: the vehicle's vehicle-wide control system determines the temperature control level based on the available charging station power and the vehicle's battery state of charge at a first moment. The vehicle-wide control system sends a first message to the battery management system, the first message carrying the temperature control level. The battery management system sends a first request to the thermal management system based on the first message and the battery temperature, the first request carrying the temperature control level. The thermal management system adjusts the battery temperature based on the first request.

[0146] In the embodiment of the present application, different temperature control levels are achieved through the power of different charging piles and the charge state of the battery. The temperature control level can be flexibly adjusted according to the available charging piles and the charge state of the battery. In this way, while ensuring the optimal charging rate, the working energy consumption of the thermal management system is saved.
