Description

Technical Field

[0001] The present application relates to the field of batteries, and in particular to a battery temperature regulation method, device, charging equipment, vehicle and storage medium. Background Art

[0002] The performance of current electric vehicle batteries is affected by temperature. When the battery is fully charged, it performs best when it is operating within the optimal temperature range. In hot or cold weather, after a long period of storage, the battery temperature is higher or lower when the user uses the vehicle again, causing the battery to be out of the optimal operating temperature range, affecting the vehicle's driving performance.

[0003] The existing methods for detecting battery temperature are basically to wake up the vehicle at a scheduled time, and then the vehicle detects whether the battery temperature is within the optimal temperature range. This method of waking up the vehicle at a scheduled time to detect the battery temperature will cause the vehicle to be woken up frequently, affecting the service life of the electrical components in the vehicle. Summary of the invention

[0004] The present application at least provides a battery temperature regulation method, device, charging equipment, vehicle and storage medium.

[0005] The present application provides a battery temperature regulation method, including: a charging device obtains temperature data corresponding to the current temperature of a battery in a vehicle; in response to the temperature data satisfying a temperature regulation condition, determining whether the vehicle is currently in a preset vehicle use time period; in response to the vehicle being in the preset vehicle use time period, sending a wake-up command to the vehicle; wherein the wake-up command is used to instruct the vehicle to perform a temperature detection on the battery, so that the vehicle adjusts the temperature of the battery based on the temperature detection result.

[0006] In the above scheme, when the vehicle is in a dormant state, the charging device may not be able to directly obtain the current temperature of the battery in the vehicle, but the temperature data corresponding to the current temperature of the battery can simulate the current temperature of the battery. When the charging device detects that the temperature data corresponding to the current temperature of the battery in the vehicle meets the temperature adjustment conditions, it determines whether the vehicle is currently in a preset vehicle use time period. If it is determined that the vehicle is currently in the preset vehicle use time period, a wake-up command can be sent to the vehicle, so that the vehicle can perform temperature detection on the battery in the vehicle after receiving the wake-up command, and then adjust the battery temperature according to the result of the temperature detection. Compared with the timed wake-up of the vehicle to detect the battery temperature, this scheme can reduce the number of times the vehicle is woken up and increase the service life of various electrical components in the vehicle.

[0007] In some embodiments, before sending a wake-up command to the vehicle, the battery temperature adjustment method also includes: in response to the vehicle being in a preset vehicle use time period, determining whether the distance between the terminal device and the charging device is less than or equal to a preset distance, the terminal device being a device associated with the vehicle; in response to the distance between the terminal device and the charging device being less than or equal to the preset distance, executing the step of sending a wake-up command to the vehicle.

[0008] In the above scheme, before sending a wake-up command to the vehicle, if it is detected that the distance between the terminal device and the charging device is less than or equal to the preset distance, it means that the user currently needs to use the vehicle. If the distance between the terminal device and the charging device is too far, it means that the user probably does not currently need to use the vehicle. Therefore, this scheme sends a wake-up command to the vehicle only when it detects that the distance between the terminal device and the charging device is less than or equal to the preset distance, which can reduce the occurrence of erroneous wake-up of the vehicle when the user has no need to use the vehicle.

[0009] In some embodiments, before determining whether the distance between the terminal device and the charging device is less than or equal to a preset distance, the battery temperature adjustment method also includes: receiving the current position of the terminal device sent by the terminal device; and using the distance between the current position and the current position of the charging device as the distance between the terminal device and the charging device.

[0010] In the above scheme, the charging device establishes a connection with the terminal device, receives the current location of the terminal device sent by the terminal device, and then determines the distance between the terminal device and the charging device based on the current location of the terminal device and the location of the charging device. Compared with methods such as setting a distance detection device on the charging device, this scheme has lower design costs for the charging device.

[0011] In some embodiments, in response to the vehicle being in a preset vehicle usage time period, a wake-up command is sent to the vehicle, including: in response to the vehicle being in a preset vehicle usage time period, sending a temperature adjustment request to a terminal device, which is a device associated with the vehicle; receiving temperature adjustment confirmation information sent by the terminal device, the temperature adjustment confirmation information including confirmation information on the need or non-necessity of temperature adjustment of the battery, confirmation information on immediate temperature adjustment or temperature adjustment after a certain length of time, and one or more of the vehicle usage time; sending a wake-up command to the vehicle based on the temperature adjustment confirmation information.

[0012] In the above scheme, by detecting that the vehicle is currently in a preset vehicle usage time period, and then sending a temperature adjustment request to the terminal device, it is convenient for the user to use the terminal device to set the start time for battery temperature adjustment or whether there is a need to adjust the battery temperature, etc. After the charging device receives the temperature adjustment confirmation information sent by the terminal device, if the temperature adjustment confirmation information carries confirmation information that the user does not need to adjust the battery temperature, then no wake-up command is sent to the vehicle. If the temperature adjustment confirmation information carries confirmation information or vehicle usage time for immediate temperature adjustment or temperature adjustment after a certain period of time, then the charging device can send a wake-up command to the vehicle at the corresponding time.

[0013] In some embodiments, in response to the vehicle being in a preset vehicle usage time period, a wake-up command is sent to the vehicle, including: in response to the vehicle being in a preset vehicle usage time period, a temperature adjustment request is sent to a terminal device, so that the terminal device sends a temperature adjustment command to the vehicle based on the temperature adjustment request; wherein the terminal device is a device associated with the vehicle, and the temperature adjustment command is used to instruct the vehicle to perform a temperature detection on the battery, so that the vehicle adjusts the temperature of the battery based on the temperature detection result.

[0014] In the above scheme, by determining that the vehicle is in a preset vehicle usage time period, the terminal device sends a temperature adjustment instruction directly to the vehicle after receiving the temperature adjustment request. The temperature adjustment instruction can wake up the vehicle, and then the vehicle performs temperature detection on the battery after waking up and then adjusts the temperature of the battery according to the temperature detection result.

[0015] In some embodiments, the charging device obtains temperature data corresponding to the current temperature of the battery in the vehicle, including: obtaining the ambient temperature of the environment in which the vehicle is located; and determining the temperature data corresponding to the current temperature of the battery based on the ambient temperature.

[0016] In the above scheme, the longer the vehicle is parked in the environment, the closer the temperature of the battery in the vehicle may be to the ambient temperature. The ambient temperature can be directly used as the temperature data corresponding to the current temperature of the battery, or the temperature data corresponding to the current temperature of the battery can be estimated based on the ambient temperature and the heat dissipation power of the battery.

[0017] In some embodiments, the charging device obtains temperature data corresponding to the current temperature of the battery in the vehicle, including: obtaining the internal temperature and ambient temperature of the charging device; based on a preset association relationship, the internal temperature and the ambient temperature, determining the temperature data corresponding to the current temperature of the battery, the preset association relationship being the association relationship between the internal temperature and ambient temperature of the charging device and the temperature of the battery.

[0018] In the above scheme, by detecting the internal temperature of the charging device and the ambient temperature, the temperature of the battery in the vehicle can be determined based on the pre-established association relationship. The vehicle does not need to be in an awake state. After the vehicle detects the temperature of the battery, the temperature is sent to the charging device through the vehicle, thereby reducing energy consumption on the vehicle side.

[0019] In some embodiments, the battery temperature regulation method also includes: determining whether the temperature data corresponding to the current temperature of the battery is not less than a first preset temperature or not greater than a second preset temperature, and the first preset temperature is greater than the second preset temperature; in response to the temperature data corresponding to the current temperature being not less than the first preset temperature or not greater than the second preset temperature, determining that the temperature data corresponding to the current temperature of the battery meets the temperature regulation conditions.

[0020] In the above scheme, a battery temperature that is too high or too low is not conducive to the operation of the battery. By detecting that the battery temperature is too high or too low, the battery temperature is adjusted, and the battery can be controlled to be in a better operating temperature range.

[0021] In some embodiments, in response to the vehicle being in a preset vehicle usage time period, a wake-up command is sent to the vehicle, including: the charging device sends the wake-up command to the vehicle using a communication line between the charging device and the vehicle; or the charging device sends the wake-up command to the vehicle using a wireless communication connection between the charging device and the vehicle.

[0022] In the above solution, the wake-up command is sent to the vehicle via wired or wireless means, which can improve the diversity of signal transmission methods.

[0023] The present application provides a battery temperature regulation method, comprising: a vehicle receiving a wake-up instruction sent by a charging device, the wake-up instruction is sent by the charging device based on the battery temperature regulation method provided in the first aspect; in response to the wake-up instruction, temperature detection is performed on a battery in the vehicle to obtain a temperature detection result; based on the temperature detection result, the temperature of the battery is regulated.

[0024] In the above scheme, when the charging device detects that the temperature data corresponding to the current temperature of the battery in the vehicle meets the temperature adjustment conditions, it determines whether the vehicle is currently in a preset vehicle use time period. If it is determined that the vehicle is currently in the preset vehicle use time period, a wake-up command can be sent to the vehicle so that the vehicle can perform temperature detection on the battery in the vehicle after receiving the wake-up command, and then adjust the battery temperature according to the result of the temperature detection. Compared with the timed wake-up of the vehicle to detect the battery temperature, this scheme can reduce the number of times the vehicle is woken up and increase the service life of various electrical components in the vehicle.

[0025] In some embodiments, the battery temperature adjustment method also includes: the vehicle receives a temperature adjustment instruction sent by a terminal device, the temperature adjustment instruction is made by the terminal device after receiving a temperature adjustment request sent by a charging device, and the temperature adjustment instruction is made when the charging device detects that the temperature data corresponding to the current temperature of the battery meets the temperature adjustment conditions and the vehicle is currently in a vehicle use time period; in response to the temperature adjustment instruction, the battery in the vehicle is temperature detected to obtain a temperature detection result.

[0026] In the above scheme, after receiving the temperature adjustment instruction from the terminal device, the vehicle can also wake up and perform temperature detection on the battery, so as to adjust the temperature of the battery according to the temperature detection result.

[0027] In some embodiments, the battery temperature regulation method also includes: determining a charging strategy for the battery based on the temperature detection result, the charging strategy including the size of the charging current for the battery requested from the charging device and / or the charging start conditions; and sending a charging request to the charging device according to the charging strategy.

[0028] In the above scheme, the charging strategy determined according to the temperature detection result is compared with using a single charging strategy. In this scheme, the charging strategy determined according to the temperature of the battery is coordinated with the temperature adjustment method, which has less impact on the battery.

[0029] In some embodiments, based on the temperature detection result, a charging strategy for the battery is determined, including: in response to the detected temperature of the battery being not greater than a preset minimum temperature or not less than a preset maximum temperature, determining that the magnitude of the charging current is the sum of the current required for temperature regulation and the charging current allowed by the battery, and a condition for starting charging is that the temperature of the battery has been adjusted to a preset charging temperature; or, in response to the detected temperature of the battery being greater than a preset minimum temperature and less than a preset maximum temperature, determining that the magnitude of the charging current is the current required for temperature regulation, and a condition for starting charging is that temperature regulation of the battery has begun.

[0030] In the above scheme, when it is detected that the temperature of the battery is too low or too high, charging the battery while the battery temperature is being adjusted may cause the battery temperature to be too low and the battery cannot be charged well; or when the battery temperature is too high, it is likely to cause the battery temperature to continue to rise during the charging process. Therefore, the charging condition for starting this scheme is that the battery temperature has been adjusted to a preset charging temperature. In addition, because the battery is generally powered during the temperature adjustment process, the charging current can be the charging current allowed by the battery and the current lost during the temperature adjustment process. If the battery is charged while the temperature is adjusted, in order to reduce overcurrent, the charging current can be less than or equal to the current required for temperature adjustment of the battery.

[0031] In some embodiments, the battery temperature regulation method further includes: based on a wake-up instruction, detecting the temperature in the passenger compartment of the vehicle; in response to the temperature in the passenger compartment being not within a preset temperature range, controlling the air conditioner in the vehicle to regulate the temperature in the passenger compartment.

[0032] In the above scheme, the temperature in the passenger compartment of the vehicle is detected, and then when the temperature in the passenger compartment is not within the preset temperature range, the air conditioner in the vehicle is controlled to adjust the temperature in the passenger compartment, so that the temperature in the passenger compartment can be maintained within the preset temperature range, providing users with a better riding environment.

[0033] In some embodiments, controlling the air conditioner in the vehicle to adjust the temperature in the passenger compartment includes: obtaining the distance between the vehicle and the terminal device; based on the distance, determining a strategy for adjusting the temperature in the passenger compartment, the adjustment strategy including the start time of temperature adjustment, air conditioner power and / or air outlet gear.

[0034] In the above scheme, by obtaining the distance between the vehicle and the terminal device, and then determining the strategy for adjusting the temperature in the passenger compartment based on the distance, the temperature adjustment method in the passenger compartment is made more flexible, and it is also convenient for the user to ensure that the temperature in the passenger compartment is within a preset temperature range when the user arrives in the vehicle.

[0035] In some embodiments, the battery temperature adjustment method further includes: in response to the vehicle detecting that the temperature of the battery has been adjusted to the target temperature, the vehicle sends a preset message to the terminal device to inform the user that the vehicle has completed the temperature adjustment.

[0036] In the above scheme, by detecting that the temperature of the battery has been adjusted to the target temperature, a preset message is sent to the terminal device, which can facilitate the user to understand the battery temperature in the vehicle in a timely manner.

[0037] The present application provides a battery temperature adjustment device, including a temperature acquisition module and a processing module; the temperature acquisition module is used for a charging device to obtain temperature data corresponding to the current temperature of a battery in a vehicle; the processing module is used to determine whether the vehicle is currently in a preset vehicle use time period in response to the temperature data satisfying a temperature adjustment condition; and the processing module is also used to send a wake-up instruction to the vehicle in response to the vehicle being in the preset vehicle use time period; wherein the wake-up instruction is used to instruct the vehicle to perform temperature detection on the battery, so that the vehicle adjusts the temperature of the battery based on the temperature detection result.

[0038] The present application provides a battery temperature regulation device, including: a data receiving module, a temperature detection module and a temperature regulation module; the data receiving module is used for a vehicle to receive a wake-up instruction sent by a charging device, and the wake-up instruction is sent by the charging device based on the battery temperature regulation method provided in the first aspect; the temperature detection module is used to respond to the wake-up instruction, perform temperature detection on the battery in the vehicle, and obtain a temperature detection result; the temperature regulation module is used to regulate the temperature of the battery based on the temperature detection result.

[0039] The present application provides a charging device, including a first memory and a first processor, wherein the first processor is used to execute program instructions stored in the first memory to implement the battery temperature adjustment method provided in the first aspect above.

[0040] The present application provides a vehicle, including a second memory and a second processor, wherein the second processor is used to execute program instructions stored in the second memory to implement the battery temperature regulation method provided in the second aspect above.

[0041] The present application provides a computer-readable storage medium having program instructions stored thereon. When the program instructions are executed by a processor, the battery temperature regulation method provided in the first aspect or the second aspect is implemented.

[0042] In the above scheme, when the charging device detects that the temperature data corresponding to the current temperature of the battery in the vehicle meets the temperature adjustment conditions, it determines whether the vehicle is currently in a preset vehicle use time period. If it is determined that the vehicle is currently in the preset vehicle use time period, a wake-up command can be sent to the vehicle so that the vehicle can perform temperature detection on the battery in the vehicle after receiving the wake-up command, and then adjust the battery temperature according to the result of the temperature detection. Compared with the timed wake-up of the vehicle to detect the battery temperature, this scheme can reduce the number of times the vehicle is woken up and increase the service life of various electrical components in the vehicle.

[0064] The scheme of the embodiment of the present application is described in detail below in conjunction with the drawings of the specification.

[0065] In the following description, for the purpose of explanation rather than limitation, specific details such as specific subsystem structures, interfaces, and technologies are provided to facilitate a thorough understanding of the present application.

[0066] The term "and / or" in this article is only a description of the association relationship of associated objects, indicating that there may be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the objects associated before and after are in an "or" relationship. In addition, "many" in this article means two or more than two. In addition, the term "at least one" in this article means any combination of at least two of any one or more of a plurality of, for example, including at least one of A, B, and C, can mean including any one or more elements selected from the set consisting of A, B, and C.

[0067] The existing methods for detecting battery temperature are basically to wake up the vehicle at a scheduled time, and then the vehicle detects whether the battery temperature is within the optimal temperature range. This method of waking up the vehicle at a scheduled time to detect the battery temperature will cause the vehicle to be woken up frequently, affecting the service life of the electrical components in the vehicle.

[0068] When the vehicle is in a dormant state, the charging device may not be able to directly obtain the current temperature of the battery in the vehicle, but it can estimate the approximate value of the current battery temperature to simulate the current temperature of the battery. For example, the current temperature of the battery can be simulated by the ambient temperature or the temperature in the charging device. The temperature data corresponding to the current temperature of the battery obtained by the charging device can simulate the current temperature of the battery. This solution uses the non-dormant characteristic of the charging device to detect the temperature data corresponding to the current temperature of the battery in the vehicle. When the temperature is detected to be too high or too low, it determines whether the vehicle is in a preset vehicle use time period. If the vehicle is also currently in the preset vehicle use time period, a wake-up command is sent to the vehicle. After receiving the wake-up command, the vehicle detects the temperature of the battery, and the vehicle adjusts the temperature of the battery according to the temperature detection result of the battery.

[0069] See also Figure 1, the connection diagram between the charging device, the vehicle and the terminal device in this embodiment is as follows: the charging device can be inserted into the vehicle through the charging gun to realize the charging connection between the charging device and the vehicle.

The wireless method includes a general wireless packet service (General Packet Radio Service, GPRS), a code division multiple access (Code Division Multiple Access, CDMA), a wireless gateway, etc., and this embodiment does not limit the communication method between the charging device and the vehicle. In other embodiments, the vehicle is connected to the charging device, and then the charging device is connected to the terminal device to realize the connection between the vehicle and the terminal device. The charging device can be a device such as a charging pile that can charge the battery in the vehicle, and the terminal device can be a user's mobile phone, car keys and other devices. Optionally, when the charging device establishes a connection with the terminal device, the connection interface of the terminal device can specify the terminal device to establish an association with the vehicle, so that a connection relationship can be established between the charging device, the vehicle and the terminal device. In other embodiments, if the charging gun on the charging pile is inserted into the vehicle, if the charging pile establishes a connection with the terminal device, the connected terminal device is considered to be the terminal device associated with the vehicle. Among them, the connection method between the charging device and the terminal device can be a direct communication connection between the charging device and the terminal device; or the charging device can be a communication connection with the terminal device via the vehicle's communication module. In addition, the vehicle can still provide a communication relay function even when it is in a dormant state or a power-off state.

[0074] In the battery 100, there may be multiple battery cells 20, and the multiple battery cells 20 may be connected in series, in parallel, or in a mixed connection. A mixed connection means that the multiple battery cells 20 are both connected in series and in parallel. The multiple battery cells 20 may be directly connected in series, in parallel, or in a mixed connection, and then the whole formed by the multiple battery cells 20 is accommodated in the box 10; of course, the battery 100 may also be a battery module formed by connecting multiple battery cells 20 in series, in parallel, or in a mixed connection, and then the multiple battery modules are connected in series, in parallel, or in a mixed connection to form a whole, and accommodated in the box 10. The battery 100 may also include other structures, for example, the battery 100 may also include a busbar component for realizing electrical connection between the multiple battery cells 20.

[0076] The battery cell 20 refers to the smallest unit that makes up the battery. Figure 4 The battery cell 20 includes an end cover 21, a shell 22, an electrode assembly 23 and other functional components.

[0077] The end cap 21 refers to a component that covers the opening of the shell 22 to isolate the internal environment of the battery cell 20 from the external environment. Without limitation, the shape of the end cap 21 can be adapted to the shape of the shell 22 to match the shell 22. Optionally, the end cap 21 can be made of a material with a certain hardness and strength (such as aluminum alloy), so that the end cap 21 is not easily deformed when squeezed and collided, so that the battery cell 20 can have a higher structural strength and the safety performance can also be improved. Functional components such as electrode terminals 21a can be provided on the end cap 21. The electrode terminal 21a can be used to electrically connect to the electrode assembly 23 for outputting or inputting electrical energy of the battery cell 20. In some embodiments, the end cap 21 can also be provided with a pressure relief mechanism for releasing the internal pressure when the internal pressure or temperature of the battery cell 20 reaches a threshold. The material of the end cap 21 can also be a variety of materials, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., and the embodiments of the present application do not impose special restrictions on this. In some embodiments, an insulating member may be provided inside the end cap 21, and the insulating member may be used to isolate the electrical connection components in the housing 22 from the end cap 21 to reduce the risk of short circuit. For example, the insulating member may be plastic, rubber, or the like.

[0078] The shell 22 is a component used to cooperate with the end cap 21 to form the internal environment of the battery cell 20, wherein the formed internal environment can be used to accommodate the electrode assembly 23, the electrolyte and other components. The shell 22 and the end cap 21 can be independent components, and an opening can be set on the shell 22, and the internal environment of the battery cell 20 is formed by covering the opening with the end cap 21 at the opening. Without limitation, the end cap 21 and the shell 22 can also be integrated. Specifically, the end cap 21 and the shell 22 can form a common connection surface before other components are put into the shell, and when the interior of the shell 22 needs to be encapsulated, the end cap 21 covers the shell 22. The shell 22 can be of various shapes and sizes, such as a rectangular parallelepiped, a cylindrical shape, a hexagonal prism, etc. Specifically, the shape of the shell 22 can be determined according to the specific shape and size of the electrode assembly 23. The material of the shell 22 can be various, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., and the embodiment of the present application does not impose any special restrictions on this.

[0079] The electrode assembly 23 is a component in the battery cell 100 where electrochemical reactions occur. One or more electrode assemblies 23 may be included in the housing 22. The electrode assembly 23 is mainly formed by winding or stacking positive and negative electrode sheets, and a separator is usually provided between the positive and negative electrode sheets. The parts of the positive and negative electrode sheets with active materials constitute the main body of the electrode assembly, and the parts of the positive and negative electrode sheets without active materials each constitute a tab 23a. The positive tab and the negative tab may be located together at one end of the main body or respectively at both ends of the main body. During the charge and discharge process of the battery, the positive active material and the negative active material react with the electrolyte, and the tab 23a connects the electrode terminals to form a current loop.

[0080] In some embodiments, see Figure 5 The charging device provided in this embodiment includes a memory 51 and a processor 52. The processor 52 is used to execute the program instructions stored in the memory 51 to implement the above Figure 6 Corresponding steps in the battery temperature adjustment method embodiment. In a specific implementation scenario, the device 50 may include but is not limited to: computer equipment, power equipment, microcomputers, desktop computers, servers, and in addition, the device 50 may also include mobile devices such as laptops and tablet computers, which are not limited here.

[0081] Specifically, the processor 52 is used to control itself and the memory 51 to implement the steps in any of the above-mentioned battery temperature regulation method embodiments. The processor 52 can also be called a CPU (Central Processing Unit). The processor 52 may be an integrated circuit chip with signal processing capabilities. The processor 52 can also be a general-purpose processor, a digital signal processor (Digital Signal Processor, DSP), an application-specific integrated circuit (Application Specific Integrated Circuit, ASIC), a field programmable gate array (Field-Programmable Gate Array, FPGA) or other programmable logic devices, discrete gates or transistor logic devices, discrete hardware components. The general-purpose processor can be a microprocessor or the processor can also be any conventional processor, etc. In addition, the processor 52 can be implemented by an integrated circuit chip.

[0082] In some other embodiments, the charging device 50 further includes a charging gun (not shown), which is used to connect to a charging socket in the vehicle.

[0083] In the above scheme, when the charging device detects that the temperature data corresponding to the current temperature of the battery in the vehicle meets the temperature adjustment conditions, it determines whether the vehicle is currently in a preset vehicle use time period. If it is determined that the vehicle is currently in the preset vehicle use time period, a wake-up command can be sent to the vehicle so that the vehicle can perform temperature detection on the battery in the vehicle after receiving the wake-up command, and then adjust the battery temperature according to the result of the temperature detection. Compared with the timed wake-up of the vehicle to detect the battery temperature, this scheme can reduce the number of times the vehicle is woken up and increase the service life of various electrical components in the vehicle.

[0084] See also Figure 6 The battery temperature regulation method provided in this application can be applied to the above-mentioned charging device or Fig. 9 The temperature regulating device provided, the battery temperature regulating method may include the contents of the following steps S11 to S13. Step S11: The charging device obtains temperature data corresponding to the current temperature of the battery in the vehicle. Step S12: In response to the temperature data satisfying the temperature regulation condition, it is determined whether the vehicle is currently in a preset vehicle use time period. Step S13: In response to the vehicle being in the preset vehicle use time period, a wake-up instruction is sent to the vehicle, wherein the wake-up instruction is used to instruct the vehicle to perform a temperature detection on the battery so that the vehicle adjusts the temperature of the battery based on the temperature detection result.

[0085] The battery may be a battery cell, a battery module or a battery pack. The structure of the battery is as described above and will not be elaborated here. A charging gun is provided on the charging device, and the battery can be charged by cooperating with the charging socket on the vehicle. The temperature data corresponding to the current temperature of the battery may be the current temperature of the battery estimated by the charging device. There may be an error between the temperature data and the current actual temperature of the battery, but it can be considered that the error is within an allowable range. The charging device may obtain the temperature data corresponding to the current temperature of the battery in the vehicle by obtaining the internal temperature and the ambient temperature of the charging device, and then estimating the temperature data corresponding to the current temperature of the battery based on the temperature of the charging device and the ambient temperature. It may also be that a temperature-sensitive element or a temperature detection element is provided on the charging gun, and the temperature-sensitive element or temperature detection element on the charging gun detects the temperature of the charging socket in the vehicle, and estimates the temperature data corresponding to the current temperature of the battery based on the temperature of the charging socket. The manner in which the charging device obtains the temperature data corresponding to the current temperature of the battery is not specifically limited here. The temperature adjustment condition may be that the temperature of the battery is high or low. Generally, if the temperature of the battery is too high or too low, it will affect the performance of the battery. Therefore, when it is determined that the temperature data corresponding to the temperature of the battery is too high or too low, it can be determined that the temperature data corresponding to the current temperature of the battery meets the temperature adjustment condition. The preset vehicle use time may be a preset time period that the vehicle may be used. The preset vehicle use time period of the vehicle can be set in multiple ways. For example, the user can preset 8:00 to 10:00 a.m. every day as the preset vehicle use time period. If the current time is 7:00 a.m., it is determined that the vehicle time is not in the preset vehicle use time period. If the current time is 8:30 a.m., it is determined that the vehicle is currently in the preset vehicle use time period. After the charging device is connected to the vehicle, the preset vehicle use time period of the vehicle can be sent by the vehicle to the power device, or after the charging device is connected to the terminal device, the preset vehicle use time period of the vehicle can be sent by the terminal device to the charging device. The way in which the charging device obtains the preset vehicle use time period of the vehicle is not specifically limited here. The wake-up instruction may be an instruction containing various contents. Exemplarily, the wake-up instruction is an instruction sent by the charging device to the vehicle to switch the electrical components in the vehicle from the low power consumption working mode to the normal working mode. After the vehicle receives the instruction, it switches the electrical components in the vehicle from the low-power working mode to the normal working mode, thereby waking up the electrical components in the vehicle to detect the temperature of the battery. For example, the electrical components in the vehicle awakened by the wake-up instruction may be a VCU or a BMS, and the battery temperature is detected using the VCU or the BMS. In an embodiment of the present application, the wake-up instruction may be a level wake-up instruction, an edge wake-up instruction, or a resistance signal, etc. The embodiment of the present application does not limit the type of wake-up instruction. For example, the edge wake-up instruction includes a control pilot function signal (ControlPilot function, CP). The CP signal is used to monitor the function of the interaction between the electric vehicle and the charging device.The CP signal is an active signal and can be used as a wake-up source. The processor sends the CP signal to the vehicle to wake up the vehicle. The specific form of the wake-up instruction is not specifically limited here.

[0086] In the above scheme, when the charging device detects that the temperature data corresponding to the current temperature of the battery in the vehicle meets the temperature adjustment conditions, it determines whether the vehicle is currently in a preset vehicle use time period. If it is determined that the vehicle is currently in the preset vehicle use time period, a wake-up command can be sent to the vehicle so that the vehicle can perform temperature detection on the battery in the vehicle after receiving the wake-up command, and then adjust the battery temperature according to the result of the temperature detection. Compared with the timed wake-up of the vehicle to detect the battery temperature, this scheme can reduce the number of times the vehicle is woken up and increase the service life of various electrical components in the vehicle.

[0087] In some embodiments, before sending a wake-up command to the vehicle, the battery temperature adjustment method further includes the following steps: in response to the vehicle being in a preset vehicle use time period, determining whether the distance between the terminal device and the charging device is less than or equal to a preset distance. The terminal device is a device associated with the vehicle, such as a user's mobile phone, a car key, a tablet, or any other device that is connected to the charging device. In response to the distance between the terminal device and the charging device being less than or equal to the preset distance, the step of sending a wake-up command to the vehicle is executed.

[0088] Before determining whether the distance between the terminal device and the charging device is less than or equal to the preset distance, the distance between the terminal device and the charging device can be obtained first. Among them, the way to obtain the distance between the terminal device and the charging device can be that after the connection between the terminal device and the charging device is established, the charging device sends its installation location to the terminal device, and then the terminal device determines the position of the terminal device itself according to GPS positioning, WIFI positioning or visual positioning, and then determines the distance between the two according to the position of the terminal device itself and the position between the charging devices, and then sends the distance to the charging device. Alternatively, the way to obtain the distance between the terminal device and the charging device can also be to receive the position of the terminal device itself sent by the terminal device, and then obtain the position of the charging device according to the GPS device in the charging device or obtain the charging device installation position pre-saved in the charging device, so as to determine the distance between the charging device and the terminal device. There are many ways to obtain the distance between the charging device and the terminal device, which are not specifically limited here. The preset distance can be received by the charging device from the terminal device, or determined according to a pre-set setting. Exemplarily, after the charging device establishes a connection with the terminal device, the charging device may send a preset distance confirmation request to the terminal device, so that the terminal device sends a response to the charging device in response to the preset distance confirmation request, and the response includes the preset distance.

[0089] In the above scheme, before sending a wake-up command to the vehicle, if it is detected that the distance between the terminal device and the charging device is less than or equal to the preset distance, it means that the user currently needs to use the vehicle. If the distance between the terminal device and the charging device is too far, it means that the user probably does not currently need to use the vehicle. Therefore, this scheme sends a wake-up command to the vehicle only when it detects that the distance between the terminal device and the charging device is less than or equal to the preset distance, which can reduce the occurrence of erroneous wake-up of the vehicle when the user has no need to use the vehicle.

[0090] In some embodiments, before determining whether the distance between the terminal device and the charging device is less than or equal to a preset distance, the battery temperature adjustment method also includes: receiving the current position of the terminal device sent by the terminal device; and using the distance between the current position and the current position of the charging device as the distance between the terminal device and the charging device.

[0091] The current location of the terminal device can be determined by the terminal device through GPS or visual positioning. The current location of the charging device can be pre-set in the charging device, or a positioning element such as GPS can be set in the charging device to determine the current location of the charging device based on the positioning element. The charging device can be either a fixed device or a mobile device.

[0092] In the above scheme, the charging device establishes a connection with the terminal device, receives the current location of the terminal device sent by the terminal device, and then determines the distance between the terminal device and the charging device based on the current location of the terminal device and the location of the charging device. Compared with methods such as setting a distance detection device on the charging device, this scheme has lower design costs for the charging device.

[0093] In some embodiments, the above step S13 may include the following steps: in response to the vehicle being in a preset vehicle use time period, sending a temperature adjustment request to a terminal device. The terminal device is a device associated with the vehicle. Receive temperature adjustment confirmation information sent by the terminal device, the temperature adjustment confirmation information including confirmation information of whether or not the battery needs to be temperature adjusted, confirmation information of immediately adjusting the temperature or extending the temperature adjustment after a certain length of time, and one or more of the vehicle use time.

[0094] In some other embodiments, the temperature adjustment confirmation information may also include the start time of temperature adjustment for the battery, and a wake-up instruction is sent to the vehicle at the start time. Taking into account the emergency situation, that is, the vehicle is in the preset vehicle use time period, but the user does not currently need to use the vehicle, by sending a temperature adjustment request to the terminal device, it is convenient to display the pop-up window corresponding to the temperature adjustment request on the terminal device, and then the user can choose to cancel the temperature adjustment on the pop-up window, or enter the temperature adjustment start time or vehicle use time on the pop-up window. The temperature adjustment start time can be to adjust the temperature immediately or extend the temperature adjustment after a certain length of time. After receiving the cancellation of temperature adjustment confirmation information input by the user, the terminal device generates temperature adjustment confirmation information that does not require temperature adjustment for the battery and sends the temperature adjustment confirmation information that does not require temperature adjustment for the battery to the charging device. The charging device will not perform temperature adjustment, and will send a temperature adjustment request to the terminal device again after a predetermined time interval. The predetermined time can be pre-set by the charging device or the terminal device, or it can be temporarily set by the user in the terminal device. After receiving the temperature adjustment start time input by the user, the terminal device generates temperature adjustment confirmation information and sends the temperature adjustment confirmation information to the charging device. In other embodiments, the temperature adjustment confirmation information sent by the terminal device includes the vehicle usage time, and then the charging device determines the start time of battery temperature adjustment based on the vehicle usage time and the current battery temperature. For example, if the user determines that the vehicle will be used in 20 minutes, and the current battery temperature is too low, and it is estimated that it will take 15 minutes to heat the battery to the target temperature, the charging device will send a wake-up command to the vehicle after 5 minutes.

[0095] In the above scheme, by detecting that the vehicle is currently in a preset vehicle usage time period, and then sending a temperature adjustment request to the terminal device, it is convenient for the user to use the terminal device to set the start time for battery temperature adjustment or whether there is a need to adjust the battery temperature, etc. After the charging device receives the temperature adjustment confirmation information sent by the terminal device, if the temperature adjustment confirmation information carries confirmation information that the user does not need to adjust the battery temperature, then no wake-up command is sent to the vehicle. If the temperature adjustment confirmation information carries confirmation information or vehicle usage time for immediate temperature adjustment or temperature adjustment after a certain period of time, then the charging device can send a wake-up command to the vehicle at the corresponding time.

[0096] In some embodiments, in response to the vehicle being in a preset vehicle use time period, the step of sending a wake-up instruction to the vehicle may include: in response to the vehicle being in a preset vehicle use time period, sending a temperature adjustment request to a terminal device, so that the terminal device sends a temperature adjustment instruction to the vehicle based on the temperature adjustment request. The terminal device is a device associated with the vehicle, and the temperature adjustment instruction is used to instruct the vehicle to perform a temperature detection on the battery, so that the vehicle adjusts the temperature of the battery based on the temperature detection result.

[0097] The charging device may also receive a response from the terminal device, which may indicate that the terminal device has sent a temperature adjustment request to the vehicle, and the charging device does not need to send a wake-up instruction to the vehicle. The temperature adjustment request may be used as a wake-up instruction to wake up the vehicle. After the vehicle wakes up, the battery temperature may be detected, and the battery temperature may be adjusted according to the result of the temperature detection.

[0098] In the above scheme, by determining that the vehicle is in a preset vehicle usage time period, the terminal device sends a temperature adjustment instruction directly to the vehicle after receiving the temperature adjustment request. The temperature adjustment instruction can wake up the vehicle, and then the vehicle performs temperature detection on the battery after waking up and then adjusts the temperature of the battery according to the temperature detection result.

[0099] In some embodiments, the charging device obtains temperature data corresponding to the current temperature of the battery in the vehicle, including: obtaining the ambient temperature of the environment in which the vehicle is located; and determining the temperature data corresponding to the current temperature of the battery based on the ambient temperature.

[0100] The longer the vehicle is parked in the environment, the closer the temperature of the battery in the vehicle is to the temperature of the environment. Therefore, the temperature of the battery in the vehicle can be estimated based on the ambient temperature of the vehicle. In other embodiments, the ambient temperature can also be directly used as the temperature data corresponding to the current temperature of the battery.

[0101] In the above scheme, the longer the vehicle is parked in the environment, the closer the temperature of the battery in the vehicle may be to the ambient temperature. The ambient temperature can be directly used as the temperature data corresponding to the current temperature of the battery, or the temperature data corresponding to the current temperature of the battery can be estimated based on the ambient temperature and the heat dissipation power of the battery.

[0102] In some embodiments, the charging device may obtain the temperature data corresponding to the current temperature of the battery in the vehicle by: obtaining the internal temperature and the ambient temperature of the charging device. Based on the preset association relationship, the internal temperature and the ambient temperature, the temperature data corresponding to the current temperature of the battery is determined. The preset association relationship is the association relationship between the internal temperature and the ambient temperature of the charging device and the temperature of the battery.

[0103] Exemplarily, the preset association relationship may be a temperature change table, and the temperature of the battery may be determined according to the internal temperature and the ambient temperature of the charging device by looking up the table, and the determined battery temperature may be used as the temperature data corresponding to the current temperature of the battery. Exemplarily, the preset association relationship may also be an association relationship between the difference between the internal temperature and the ambient temperature of the charging device and the temperature of the battery. The preset association relationship may be obtained by training in advance according to the internal temperature of the charging device, the ambient temperature, and the temperature of the battery at multiple moments. The reason why the temperature of the charging device and the predicted temperature of the battery have a corresponding relationship is that the cooling rate or heating rate of the charging device is different from the cooling rate or heating rate of the battery. The cooling rate or heating rate of the charging device and the cooling rate or heating rate of the battery are related to factors such as the thermal insulation materials used by the charging device and the battery and the ambient temperature. Among them, the thermal insulation materials have a greater impact on the cooling rate or heating rate. When the thermal insulation effect of the thermal insulation material of the charging device is lower than the thermal insulation effect of the thermal insulation material of the battery, the cooling rate and heating rate of the charging device are greater than the cooling rate of the battery.

[0104] In the above scheme, by detecting the internal temperature of the charging device and the ambient temperature, and then based on the pre-established association relationship, the temperature of the battery in the vehicle can be preliminarily determined. There is no need to wake up the vehicle and use the vehicle to detect the temperature of the battery. The temperature is then sent to the charging device through the vehicle, thereby reducing energy consumption on the vehicle side.

[0105] In some embodiments, the battery temperature adjustment method further includes: determining whether the temperature data corresponding to the current temperature of the battery is not less than a first preset temperature or not greater than a second preset temperature. The first preset temperature is greater than the second preset temperature. In response to the temperature data corresponding to the current temperature being not less than the first preset temperature or not greater than the second preset temperature, determining that the temperature data corresponding to the current temperature of the battery meets the temperature adjustment condition.

[0106] The first preset temperature can be used to indicate the initial temperature at which heat dissipation is required, and the second preset temperature can be used to indicate the initial temperature at which heating is required. That is, when the temperature of the battery is greater than or equal to the first preset temperature, it is determined that the temperature data corresponding to the current temperature of the battery meets the temperature adjustment condition, that is, the battery needs to be cooled. When the temperature of the battery is less than or equal to the second preset temperature, it is determined that the temperature data corresponding to the current temperature of the battery meets the temperature adjustment condition, that is, the battery needs to be heated. The first preset temperature and the second preset temperature can be pre-set, or they can be carried in the response sent by the terminal device to the charging device after the charging device and the terminal device establish a connection and send a preset temperature confirmation to the terminal device.

[0107] In the above scheme, a battery temperature that is too high or too low is not conducive to the operation of the battery. By detecting that the battery temperature is too high or too low, the battery temperature is adjusted, and the battery can be controlled to be in a better operating temperature range.

[0108] In some embodiments, the step of sending a wake-up command to the vehicle in response to the vehicle being in a preset vehicle usage time period includes: the charging device sends the wake-up command to the vehicle using a communication line between the charging device and the vehicle; or the charging device sends the wake-up command to the vehicle using a wireless communication connection between the charging device and the vehicle.

[0109] The communication line can be set in the charging gun. After the charging gun is connected to the charging socket on the vehicle, the communication line in the charging gun is connected to the communication interface in the charging socket to achieve communication connection between the charging device and the vehicle. Wireless communication includes but is not limited to mobile network communication, local area network communication or Bluetooth communication.

[0110] In the above solution, the wake-up command is sent to the vehicle via wired or wireless means, which can improve the diversity of signal transmission methods.

[0111] See also Figure 7 The battery temperature adjustment method provided in this embodiment can be applied to a vehicle or can also be applied to Fig.10 The battery temperature regulating device shown. The present application provides a battery temperature regulating method, comprising: step S21: the vehicle receives a wake-up instruction sent by a charging device. The wake-up instruction is sent by the charging device based on the battery temperature regulating method provided in the first aspect; step S22: in response to the wake-up instruction, the temperature of the battery in the vehicle is detected to obtain a temperature detection result. Step S23: based on the temperature detection result, the battery is temperature regulated.

[0112] The manner in which the charging device sends a wake-up instruction to the vehicle based on the above-mentioned battery temperature adjustment method is as described above, and will not be repeated here. After the vehicle receives the wake-up instruction sent by the charging device, the vehicle switches itself from the low-power working mode to the normal working mode according to the wake-up instruction, and detects the temperature of the battery in the vehicle. In some embodiments, only the battery management system (BMS) in the vehicle can be awakened according to the wake-up instruction, and the BMS obtains the temperature of the battery and detects the temperature. In some embodiments, the BMS and the vehicle controller VCU are awakened at the same time according to the wake-up instruction, and the BMS uploads the obtained battery temperature to the VCU through the CAN bus, and the VCU detects the temperature of the battery. The temperature detection result may include the temperature of the battery. Based on the temperature detection result, the method of adjusting the temperature of the battery is to determine the adjustment rate of the battery temperature or the time to start the temperature adjustment of the battery according to the temperature of the battery. In some embodiments, if the vehicle detects that the temperature of the battery is between the first preset temperature and the second preset temperature, that is, the charging device detects an error, and the temperature of the battery does not meet the temperature adjustment condition, the battery may not be temperature adjusted, and feedback information may be sent to the charging device so that the charging device determines the cause of the temperature detection error to improve the accuracy of subsequent temperature detection. In some embodiments, if the vehicle detects that the temperature data corresponding to the current temperature of the battery meets the temperature adjustment condition, the battery is subjected to the temperature condition.

[0113] In the above scheme, when the charging device detects that the temperature data corresponding to the current temperature of the battery in the vehicle meets the temperature adjustment conditions, it determines whether the vehicle is currently in a preset vehicle use time period. If it is determined that the vehicle is currently in the preset vehicle use time period, a wake-up command can be sent to the vehicle so that the vehicle can perform temperature detection on the battery in the vehicle after receiving the wake-up command, and then adjust the battery temperature according to the result of the temperature detection. Compared with the timed wake-up of the vehicle to detect the battery temperature, this scheme can reduce the number of times the vehicle is woken up and increase the service life of various electrical components in the vehicle.

[0114] In some embodiments, the temperature adjustment method may also include: the vehicle receives a temperature adjustment instruction sent by a terminal device, the temperature adjustment instruction is made by the terminal device after receiving a temperature adjustment request sent by a charging device, and the temperature adjustment instruction is made when the charging device detects that the temperature data corresponding to the current temperature of the battery meets the temperature adjustment conditions and the vehicle is currently in a vehicle use time period; in response to the temperature adjustment instruction, the battery in the vehicle is temperature detected to obtain a temperature detection result.

[0115] The temperature adjustment request can also be used as a wake-up instruction. After the vehicle is woken up, the battery temperature can be detected. The temperature detection result obtained by the vehicle from detecting the battery temperature is more accurate than the temperature data detected by the charging device.

[0116] In the above scheme, after receiving the temperature adjustment instruction from the terminal device, the vehicle can also wake up and perform temperature detection on the battery, so as to adjust the temperature of the battery according to the temperature detection result.

[0117] In some embodiments, the battery temperature regulation method further includes: determining a charging strategy for the battery based on the temperature detection result. The charging strategy includes the magnitude of the charging current for the battery and / or the charging start condition requested from the charging device. According to the charging strategy, a charging request is sent to the charging device.

[0118] Among them, the energy required for temperature regulation of the battery can be provided by the battery, so the charging strategy for the battery can be determined in the process of temperature regulation of the battery. For example, the charging strategy may also be different depending on the way of temperature regulation of the battery. For example, if the temperature of the battery is too high, charging the battery when the battery is initially cooled may result in too low efficiency of heat dissipation and failure to cool the battery well. Therefore, the charging time of the battery can be set to reduce the problem of poor temperature regulation of the battery due to charging. The charging request may include the size of the requested charging current.

[0119] In the above scheme, the charging strategy determined according to the temperature detection result is compared with using a single charging strategy. In this scheme, the charging strategy determined according to the temperature of the battery is coordinated with the temperature adjustment method, which has less impact on the battery.

[0120] In some embodiments, the above-mentioned method of determining the charging strategy for the battery based on the temperature detection result may be: in response to the detected temperature of the battery being not greater than the preset minimum temperature or not less than the preset maximum temperature, the magnitude of the charging current is determined to be the sum of the current required for temperature regulation and the charging current allowed by the battery, and the condition for starting charging is that the temperature of the battery has been adjusted to the preset charging temperature. Or, in response to the detected temperature of the battery being greater than the preset minimum temperature and less than the preset maximum temperature, the magnitude of the charging current is determined to be the current required for temperature regulation, and the condition for starting charging is that the temperature regulation of the battery has begun.

[0121] The detected temperature of the battery is not greater than the preset minimum temperature or not less than the preset maximum temperature, the preset minimum temperature is lower than the above-mentioned second preset temperature, and the preset maximum temperature is higher than the above-mentioned first preset temperature. The preset minimum temperature can be used to indicate that if the detected temperature of the battery is lower than the preset minimum temperature, the battery cannot be charged at the same time as the temperature adjustment of the battery is started, and the preset maximum temperature can be used to indicate that if the detected temperature of the battery is higher than the preset maximum temperature, the battery cannot be charged at the same time as the temperature adjustment of the battery is started. That is, when the detected temperature of the battery is not greater than the preset minimum temperature or not less than the preset maximum temperature, the battery needs to be temperature-adjusted for a period of time before charging the battery. Exemplarily, if the detected temperature of the battery is not greater than the preset minimum temperature, the battery needs to be heated first, and after heating to the first preset charging temperature, the battery can be charged. Exemplarily, if the detected temperature of the battery is not less than the preset maximum temperature, the battery needs to be cooled first, and after cooling to the second preset charging temperature, the battery can be charged, and the second preset charging temperature is higher than the first preset charging temperature.

[0122] The charging current allowed by the battery can be the current size per unit time that needs to be requested from the charging device when the battery is normally charged, and the current required for temperature regulation can be the current lost per unit time when the battery is heated or dissipated. If the detected temperature of the battery is between the preset minimum temperature and the preset maximum temperature, the battery can be charged and temperature regulated at the same time. At this time, the current loss of the battery is the loss of temperature regulation, that is, the size of the charging current requested by the battery is the current lost by the battery for temperature regulation. In this way, the occurrence of charging overcurrent can be reduced. The battery is charged so that the state of charge (remaining power) of the battery is greater than or equal to the preset state of charge (preset remaining power). The state of charge can also be called the remaining power, which is used to reflect the remaining capacity of the battery, and its value can be positioned as the ratio of the remaining capacity to the battery capacity. Starting charging regulation means that the temperature regulation of the battery has begun, that is, when it is detected that the battery starts to discharge and the temperature regulation system regulates the temperature of the battery, it is determined that the charging condition has been met. The temperature regulation system can be a thermal management system.

[0123] In the above scheme, when it is detected that the temperature of the battery is too low or too high, charging the battery while the battery temperature is being adjusted may cause the battery temperature to be too low and the battery cannot be charged well; or when the battery temperature is too high, it is likely that the battery temperature will continue to rise during the charging process. Therefore, the charging condition for starting this scheme is that the battery temperature has been adjusted to a preset charging temperature. In addition, because the battery is generally powered during the temperature adjustment process, the charging current can be the charging current allowed by the battery and the current lost during the temperature adjustment process. If the battery is charged while the temperature is adjusted, in order to reduce the situation of charging overcurrent, the charging current can be less than or equal to the current required for temperature adjustment of the battery.

[0124] In some embodiments, the battery temperature adjustment method further includes: detecting the temperature in the passenger compartment of the vehicle based on the wake-up instruction, and controlling the air conditioner in the vehicle to adjust the temperature in the passenger compartment in response to the temperature in the passenger compartment not being within a preset temperature range.

[0125] The detection method may be to set a temperature detection element in the passenger compartment, detect the temperature in the passenger compartment through the temperature detection element, and then send the detected temperature to the controller in the vehicle. The preset temperature range may be set in advance, or the vehicle may send a confirmation request to the terminal device, and then the terminal device may send a command message to the vehicle, or the terminal device may send the preset temperature range to the charging device, and then the charging device may send a command message to the vehicle. Exemplarily, if the temperature in the passenger compartment is lower than the minimum value in the preset temperature range, the air conditioner is controlled to heat up the passenger compartment, and if the temperature in the passenger compartment is higher than the maximum value in the preset temperature range, the air conditioner is controlled to cool down the passenger compartment.

[0126] In the above scheme, the temperature in the passenger compartment of the vehicle is detected, and then when the temperature in the passenger compartment is not within the preset temperature range, the air conditioner in the vehicle is controlled to adjust the temperature in the passenger compartment, so that the temperature in the passenger compartment can be maintained within the preset temperature range, providing users with a better riding environment.

[0127] In some embodiments, controlling the air conditioner in the vehicle to adjust the temperature in the passenger compartment includes: obtaining the distance between the vehicle and the terminal device. Based on the distance, determining an adjustment strategy for the temperature in the passenger compartment, the adjustment strategy including the start time of the temperature adjustment, the power of the temperature adjustment and / or the air outlet gear.

[0128] The way to obtain the distance between the vehicle and the terminal device can be that the terminal device sends the current position of the terminal device to the vehicle, and the vehicle calculates the distance between the two. It can also be that the terminal device sends the current position of the terminal device to the charging device, and the charging device uses the distance between the charging device and the terminal device as the distance between the vehicle and the terminal device, or subtracts the length of the charging gun from the distance between the charging device and the terminal device as the distance between the vehicle and the terminal device. Optionally, if the adjustment strategy includes the start time of temperature adjustment, the farther the distance between the vehicle and the terminal device, the later the start time of temperature adjustment in the passenger compartment. Similarly, the closer the distance between the vehicle and the terminal device, the earlier the start time of temperature adjustment in the passenger compartment. Optionally, if the adjustment strategy includes the power of temperature adjustment, such as the set temperature of the air conditioner and the gear of the air conditioner, the farther the distance between the vehicle and the terminal device, the smaller the power of temperature adjustment in the passenger compartment can be, such as a lower gear or a higher set temperature. Similarly, the closer the distance between the vehicle and the terminal device, the greater the power of temperature adjustment in the passenger compartment. Optionally, the adjustment strategy includes an air outlet gear, and the larger the air outlet gear, the greater the air volume, and the smaller the air outlet gear, the smaller the air volume. Among them, if the difference between the detected temperature of the battery and the target temperature is large, and the distance between the terminal device and the vehicle is close, a larger air outlet gear can be selected, and similarly, a smaller air outlet gear can be selected. Optionally, if the adjustment strategy includes the start time of temperature adjustment and the power of temperature adjustment, the start time and the power of the air conditioner can be comprehensively determined based on the distance and energy-saving requirements. The greater the power of the air conditioner, the better the cooling or heating effect.

[0129] In the above scheme, by obtaining the distance between the vehicle and the terminal device, and then determining the strategy for adjusting the temperature in the passenger compartment based on the distance, the temperature adjustment method in the passenger compartment is made more flexible, and it is also convenient for the user to ensure that the temperature in the passenger compartment is within a preset temperature range when the user arrives in the vehicle.

[0130] In some embodiments, the battery temperature adjustment method further includes: in response to the vehicle detecting that the temperature of the battery has been adjusted to the target temperature, the vehicle sends a preset message to the terminal device to inform the user that the vehicle has completed the temperature adjustment.

[0131] The target temperature may be preset or specified by the terminal device. The vehicle may send the preset message to the terminal device in such a manner that if the vehicle and the terminal device have established a connection relationship, the vehicle may directly send the preset message to the terminal device; if the vehicle and the terminal device have not established a direct connection relationship, the vehicle may first send the preset message to the charging device, and then the charging device forwards the preset message to the terminal device. The preset message may include the current temperature of the battery and / or the passenger compartment.

[0132] In the above scheme, by detecting that the temperature of the battery has been adjusted to the target temperature, a preset message is sent to the terminal device, which can facilitate the user to understand the battery temperature in the vehicle in a timely manner.

[0133] Considering that after the charging process is completed, the vehicle will enter the dormant mode, and the battery charging temperature adjustment / cooling function will be turned off synchronously. Under cold conditions in winter, after the vehicle is fully charged and placed for a long time, the battery pack temperature is low when the user uses the vehicle again, resulting in the battery pack being out of the optimal operating temperature range, affecting the vehicle driving performance. Therefore, the battery temperature adjustment method of this scheme is proposed, so that the battery of the vehicle can be in the optimal temperature range when the user needs to use the vehicle. This scheme makes full use of the characteristics that the charging device will be in a standby state and not dormant after charging is completed, so that the vehicle can be in a dormant state, reducing the frequent and inefficient low-voltage power consumption of the vehicle. At the same time, the charging device detects the temperature change, determines that the battery needs to be kept warm, and within the daily car use time t set by the user, it can push information to the user APP. After receiving the user's feedback request for battery temperature adjustment, the charging device will wake up the whole vehicle (optionally, the vehicle can also be directly awakened through the terminal device, such as the mobile phone APP awakening the vehicle TBOX, without the need to feedback the request for battery temperature adjustment to the charging device) to adjust the battery temperature. The present invention can avoid the long-term insulation of the vehicle when there is no need to use the vehicle, resulting in energy waste. Alternatively, instead of sending a temperature adjustment request to the user's APP, the charging device detects the battery temperature and determines that the battery needs to be kept warm at this time. This time is within the daily car use time t set by the user. The charging device detects the distance D1 between the mobile phone APP and the charging device. When D1 is less than D2 (the heat preservation start distance threshold set by the user) within a preset time period (for example, 5s), it is determined that the user needs to use the car. At this time, the vehicle can be woken up through the charging device or mobile phone APP to keep the vehicle warm.

[0134] To better understand the battery temperature regulation method provided by this solution, please refer to Figure 8 .like Figure 8 As shown, the charging device and the vehicle cooperate to adjust the temperature of the battery in the vehicle as follows:

[0135] Step S101: The charging device obtains temperature data corresponding to the current temperature of the battery in the vehicle.

[0136] After the vehicle is fully charged, the charging device stops outputting charging power, the vehicle is powered off and in sleep mode, the charging device is in standby mode, and the charging gun is not unplugged. After that, the charging device detects its own temperature and the ambient temperature to estimate the current temperature of the battery and determine whether the battery needs to be heated or cooled at this time. The following takes heating as an example. The specific implementation process of step S101 can refer to the relevant description of step S11 above, which will not be repeated here.

[0137] Step S102: determining whether the temperature data corresponding to the current temperature of the battery is not less than a first preset temperature or not greater than a second preset temperature.

[0138] In response to the judgment result of step S102 that the temperature data corresponding to the current temperature is not less than the first preset temperature or not greater than the second preset temperature, step S103 or step S113 is executed. Or, in response to the judgment result of step S102 that the current temperature of the battery is greater than the second preset temperature and less than the first preset temperature, step S101 is executed.

[0139] Step S103: Determine whether the vehicle is currently in a preset vehicle use time period.

[0140] The method for determining whether the vehicle is currently in a preset vehicle usage time period can refer to the above method of this application, which will not be repeated here.

[0141] By comparing the current time, if the current time is within the daily car use time t set by the user (such as 7:30-8:30), in response to the judgment result of step S103 that the vehicle is currently in the preset car use time period, step S104 is executed; and when the judgment result of step S103 is that the vehicle is not currently in the preset car use time period, step S101 is executed, or if it is not within the daily car use time t set by the user, wait until after time t to push the message.

[0142] Step S104: Send a temperature adjustment request to the terminal device.

[0143] Exemplarily, in response to the judgment result of step S103 that the vehicle is currently in a preset vehicle use time period, the charging device immediately pushes a message to the mobile phone APP, informing the user that the current battery is not within the optimal temperature range and needs to be heated, and consults the user whether to execute "immediate heating" or "heating after delay Tmin".

[0144] Step S105: receiving temperature adjustment confirmation information sent by the terminal device.

[0145] The temperature adjustment confirmation information may include the time information for adjusting the battery temperature, such as the start time of the temperature adjustment, the user's vehicle usage time, etc. If the charging device receives the "immediate heating" command sent by the mobile phone APP, the vehicle will be woken up through the charging device. If the "heating after delay Tmin" is received, the vehicle will be woken up through the charging device after Tmin. Optionally, the mobile phone APP can also communicate directly with the vehicle TBOX, send the "immediate heating" or "heating after delay Tmin" command to the TBOX, and directly wake up the vehicle for heating.

[0146] Step S106: Send a wake-up instruction to the vehicle.

[0147] Specifically, based on the temperature adjustment confirmation information, a wake-up instruction may be sent to the vehicle at the start time of adjusting the battery temperature.

[0148] Step S107: The vehicle receives the wake-up instruction.

[0149] The wake-up command can be sent from the charging device to the vehicle, or from the terminal device to the vehicle and to the charging device at the same time.

[0150] Step S108: Perform temperature detection on the battery in the vehicle to obtain a temperature detection result.

[0151] The method of performing temperature detection on the battery in the vehicle and obtaining the temperature detection result can refer to the above method of the present application, which will not be repeated here.

[0152] Step S109: Based on the temperature detection result, the battery temperature is adjusted and a charging strategy for the battery is determined.

[0153] Based on the temperature detection result, the method of adjusting the battery temperature can refer to the above method of the present application, which will not be repeated here. After the vehicle is awakened, the BMS detects the current battery temperature TA. It is determined whether TA is ≥ the preset minimum temperature TB (the lowest temperature allowed for charging and discharging of the battery). If TA ≥ TB, the battery heating mode adopts the charging and heating mode, and the BMS requests the charging current = the current lost when the battery is heated. Based on the temperature detection result, the method of determining the charging strategy for the battery can refer to the above, which will not be repeated here. If TA < TB, the battery heating mode adopts the heating-first-then-charging mode, first using the battery's own power to heat the battery temperature to temperature TB (the lowest temperature allowed for charging and discharging of the battery), and then executing the charging and heating mode, the BMS requests the current = the charging current allowed by the battery at this time + the current lost by the thermal management during heating at this time. When the battery temperature is too high and needs to be cooled, the strategy of heating when the battery temperature is too low can be referred to. For example, if it is detected that the current temperature TA is less than or equal to the preset maximum temperature TC (the highest temperature allowed for charging and discharging of the battery), the battery cooling mode adopts the charging and cooling mode, and the BMS requests the charging current = the current lost when the battery is cooled. If TA>TV, the battery cooling mode adopts the charging after cooling mode, first using the battery's own power to dissipate the battery temperature to temperature TC (the maximum temperature allowed for charging and discharging of the battery), and then executes the charging while cooling mode. The BMS requested current = the charging current allowed by the battery at this time + the current lost by thermal management during cooling at this time.

[0154] Step S110: Send a charging request to the charging device according to the charging strategy.

[0155] Step S111: In response to the vehicle detecting that the temperature of the battery has been adjusted to the target temperature, the vehicle sends a preset message to the terminal device to inform the user that the vehicle has completed the temperature adjustment, so that the charging device can charge the battery in the vehicle in response to the charging request.

[0156] Step S112: Obtain the distance between the terminal device and the charging device.

[0157] The method for the terminal device to obtain the distance between the terminal device and the charging device can be referred to above and will not be repeated here.

[0158] Step S113: Determine whether the distance between the terminal device and the charging device is less than or equal to a preset distance.

[0159] The charging device detects the temperature and determines that the battery needs to be heated. By comparing the current moment with the daily vehicle use time t set by the user, the charging device detects the distance D1 between the mobile phone APP and the charging device in real time (such as Bluetooth or GPS ranging); when D1 is less than D2 (the insulation start distance threshold set by the user) within a preset time period, such as the preset time period is 5s (calibratable value), it is determined that the user needs to use the vehicle at this time, and the charging device immediately wakes up the vehicle.

[0160] If the judgment result of step S113 is that the distance between the terminal device and the charging device is less than or equal to the preset distance, step S106 is executed; otherwise, step S112 is executed.

[0161] In addition, if the judgment result of step S113 is that the distance between the terminal device and the charging device is less than or equal to the preset distance, step S114 may also be executed.

[0162] Step S114: Obtain the distance between the vehicle and the terminal device.

[0163] Step S115: Determine a strategy for adjusting the temperature in the passenger compartment based on the distance or the user's vehicle usage time.

[0164] After the vehicle is awakened, the temperature in the passenger compartment is detected synchronously, and the air conditioner is turned on at the appropriate time based on the comparison between the passenger compartment temperature and the set comfort temperature, the distance D1 between the charging device and the mobile phone, and the estimated time it takes the user to walk to the charging station, or the user's vehicle usage time. The system automatically selects the appropriate air conditioning power to ensure that the passenger compartment has a suitable temperature when the user arrives at the vehicle.

[0165] Step S116: adjusting the temperature in the passenger compartment according to the temperature adjustment strategy in the passenger compartment.

[0166] In the above scheme, when the charging device detects that the temperature data corresponding to the current temperature of the battery in the vehicle meets the temperature adjustment conditions, it determines whether the vehicle is currently in a preset vehicle use time period. If it is determined that the vehicle is currently in the preset vehicle use time period, a temperature adjustment request is sent to the user and a temperature adjustment confirmation message is received, or a wake-up instruction is sent to the vehicle through the distance information between the terminal device and the charging device or the vehicle, so that after receiving the wake-up instruction, the vehicle performs temperature detection on the battery in the vehicle and then adjusts the temperature of the battery according to the result of the temperature detection; at the same time, the temperature in the vehicle passenger compartment can be adjusted in time according to the user's vehicle use time or distance information. Compared with the timed vehicle wake-up to detect the battery temperature, this scheme can reduce the number of times the vehicle is woken up, increase the service life of various electrical components in the vehicle, and save energy.

[0167] See also Fig. 9 ,like Fig. 9 As shown, the first battery temperature adjustment device 30 provided in this embodiment may include: a temperature acquisition module 31 and a processing module 32; the temperature acquisition module 31 is used for the charging device to obtain temperature data corresponding to the current temperature of the battery in the vehicle; the processing module 32 is used to determine whether the vehicle is currently in a preset vehicle use time period in response to the temperature data satisfying the temperature adjustment condition; the processing module 32 is also used to send a wake-up instruction to the vehicle in response to the vehicle being in the preset vehicle use time period; wherein the wake-up instruction is used to instruct the vehicle to perform temperature detection on the battery, so that the vehicle adjusts the temperature of the battery based on the temperature detection result.

[0168] In the above scheme, when the charging device detects that the temperature data corresponding to the current temperature of the battery in the vehicle meets the temperature adjustment conditions, it determines whether the vehicle is currently in a preset vehicle use time period. If it is determined that the vehicle is currently in the preset vehicle use time period, a wake-up command can be sent to the vehicle so that the vehicle can perform temperature detection on the battery in the vehicle after receiving the wake-up command, and then adjust the battery temperature according to the result of the temperature detection. Compared with the timed wake-up of the vehicle to detect the battery temperature, this scheme can reduce the number of times the vehicle is woken up and increase the service life of various electrical components in the vehicle.

[0169] In some embodiments, before sending a wake-up command to the vehicle, the processing module 32 is also used to: in response to the vehicle being in a preset vehicle use time period, determine whether the distance between the terminal device and the charging device is less than or equal to a preset distance, the terminal device being a device associated with the vehicle; in response to the distance between the terminal device and the charging device being less than or equal to the preset distance, execute the step of sending a wake-up command to the vehicle.

[0170] In the above scheme, before sending a wake-up command to the vehicle, if it is detected that the distance between the terminal device and the charging device is less than or equal to the preset distance, it means that the user currently needs to use the vehicle. If the distance between the terminal device and the charging device is too far, it means that the user probably does not currently need to use the vehicle. Therefore, this scheme sends a wake-up command to the vehicle only when it detects that the distance between the terminal device and the charging device is less than or equal to the preset distance, which can reduce the occurrence of erroneous wake-up of the vehicle when the user has no need to use the vehicle.

[0171] In some embodiments, before determining whether the distance between the terminal device and the charging device is less than or equal to a preset distance, the processing module 32 is also used to: receive the current position of the terminal device sent by the terminal device; and use the distance between the current position and the current position of the charging device as the distance between the terminal device and the charging device.

[0172] In the above scheme, the charging device establishes a connection with the terminal device, receives the current location of the terminal device sent by the terminal device, and then determines the distance between the terminal device and the charging device based on the current location of the terminal device and the location of the charging device. Compared with methods such as setting a distance detection device on the charging device, this scheme has lower design costs for the charging device.

[0173] In some embodiments, the processing module 32 sends a wake-up command to the vehicle in response to the vehicle being in a preset vehicle usage time period, including: sending a temperature adjustment request to a terminal device in response to the vehicle being in a preset vehicle usage time period, the terminal device being a device associated with the vehicle; receiving temperature adjustment confirmation information sent by the terminal device, the temperature adjustment confirmation information including confirmation information on whether or not the battery needs to be temperature adjusted, confirmation information on immediate temperature adjustment or temperature adjustment after a certain length of time, and one or more of the vehicle usage time; sending a wake-up command to the vehicle based on the temperature adjustment confirmation information.

[0174] In the above scheme, by detecting that the vehicle is currently in a preset vehicle usage time period, and then sending a temperature adjustment request to the terminal device, it is convenient for the user to use the terminal device to set the start time for battery temperature adjustment or whether there is a need to adjust the battery temperature, etc. After the charging device receives the temperature adjustment confirmation information sent by the terminal device, if the temperature adjustment confirmation information carries confirmation information that the user does not need to adjust the battery temperature, then no wake-up command is sent to the vehicle. If the temperature adjustment confirmation information carries confirmation information or vehicle usage time for immediate temperature adjustment or temperature adjustment after a certain period of time, then the charging device can send a wake-up command to the vehicle at the corresponding time.

[0175] In some embodiments, in response to the vehicle being in a preset vehicle usage time period, the processing module 32 sends a wake-up command to the vehicle, including: in response to the vehicle being in a preset vehicle usage time period, sending a temperature adjustment request to the terminal device, so that the terminal device sends a temperature adjustment command to the vehicle based on the temperature adjustment request; wherein the terminal device is a device associated with the vehicle, and the temperature adjustment command is used to instruct the vehicle to perform a temperature detection on the battery, so that the vehicle adjusts the temperature of the battery based on the temperature detection result.

[0176] In the above scheme, by determining that the vehicle is in a preset vehicle usage time period, the terminal device sends a temperature adjustment instruction directly to the vehicle after receiving the temperature adjustment request. The temperature adjustment instruction can wake up the vehicle, and then the vehicle performs temperature detection on the battery after waking up and then adjusts the temperature of the battery according to the temperature detection result.

[0177] In some embodiments, the temperature acquisition module 31 charging device acquires temperature data corresponding to the current temperature of the battery in the vehicle, including: acquiring the ambient temperature of the vehicle's environment; and determining the temperature data corresponding to the current temperature of the battery based on the ambient temperature.

[0178] In the above scheme, the longer the vehicle is parked in the environment, the closer the temperature of the battery in the vehicle may be to the ambient temperature. The ambient temperature can be directly used as the temperature data corresponding to the current temperature of the battery, or the temperature data corresponding to the current temperature of the battery can be estimated based on the ambient temperature and the heat dissipation power of the battery.

[0179] In some embodiments, the temperature acquisition module 31 executes the steps of the above-mentioned charging device acquiring the temperature data corresponding to the current temperature of the battery in the vehicle, including: acquiring the internal temperature and the ambient temperature of the charging device; based on a preset association relationship, the internal temperature and the ambient temperature, determining the temperature data corresponding to the current temperature of the battery, the preset association relationship being the association relationship between the internal temperature and the ambient temperature of the charging device and the temperature of the battery.

[0180] In the above scheme, by detecting the internal temperature of the charging device and the ambient temperature, and then based on the pre-established association relationship, the temperature of the battery in the vehicle can be preliminarily determined. The vehicle does not need to be in an awake state. After the vehicle detects the temperature of the battery, the temperature is sent to the charging device through the vehicle, thereby reducing energy consumption on the vehicle side.

[0181] In some embodiments, the processing module 32 is also used to: determine whether the temperature data corresponding to the current temperature of the battery is not less than the first preset temperature or not greater than the second preset temperature, and the first preset temperature is greater than the second preset temperature; in response to the temperature data corresponding to the current temperature being not less than the first preset temperature or not greater than the second preset temperature, determine that the temperature data corresponding to the current temperature of the battery meets the temperature adjustment conditions.

[0182] In the above scheme, a battery temperature that is too high or too low is not conducive to the operation of the battery. By detecting that the battery temperature is too high or too low, the battery temperature is adjusted, and the battery can be controlled to be in a better operating temperature range.

[0183] In some embodiments, the processing module 32 sends a wake-up instruction to the vehicle in response to the vehicle being in a preset vehicle use time period, including: the charging device sends the wake-up instruction to the vehicle using a communication line between the charging device and the vehicle; or the charging device sends the wake-up instruction to the vehicle using a wireless communication connection between the charging device and the vehicle. Alternatively, the wake-up instruction is directly sent to the vehicle through the terminal device, and the wake-up instruction is transmitted to the charging device.

[0184] In the above scheme, sending the wake-up command to the vehicle via wired or wireless means can improve the diversity and reliability of signal transmission methods.

[0185] See also Fig.10 The second battery temperature adjustment device 40 provided in this embodiment may include: a data receiving module 41, a temperature detection module 42 and a temperature adjustment module 43; the data receiving module 41 is used for the vehicle to receive a wake-up instruction sent by a charging device or a terminal device, and the wake-up instruction is sent by the charging device based on the battery temperature adjustment method provided in the first aspect, or is directly sent by the user through the terminal device; the temperature detection module 42 is used to respond to the wake-up instruction, perform temperature detection on the battery in the vehicle, and obtain a temperature detection result; the temperature adjustment module 43 is used to adjust the temperature of the battery based on the temperature detection result.

[0186] In the above scheme, when the charging device detects that the temperature data corresponding to the current temperature of the battery in the vehicle meets the temperature adjustment conditions, it determines whether the vehicle is currently in a preset vehicle use time period. If it is determined that the vehicle is currently in the preset vehicle use time period, a wake-up command can be sent to the vehicle, so that the vehicle can perform temperature detection on the battery in the vehicle after receiving the wake-up command, and then adjust the battery temperature according to the result of the temperature detection. Compared with the timed wake-up of the vehicle to detect the battery temperature, this scheme can reduce the number of times the vehicle is woken up, increase the service life of various electrical components in the vehicle, and save energy consumption.

[0187] In some embodiments, the data receiving module 41 is also used for: the vehicle receives a temperature adjustment instruction sent by a terminal device, the temperature adjustment instruction is made by the terminal device after receiving a temperature adjustment request sent by a charging device, and the temperature adjustment instruction is made when the charging device detects that the temperature data corresponding to the current temperature of the battery meets the temperature adjustment conditions and the vehicle is currently in a vehicle use time period; the temperature detection module 42 is also used to perform temperature detection on the battery in the vehicle in response to the temperature adjustment instruction to obtain a temperature detection result.

[0188] In the above scheme, the vehicle can also wake up and detect the temperature of the battery after receiving the temperature adjustment instruction of the terminal device, so as to adjust the temperature of the battery according to the temperature detection result. In some embodiments, the second battery temperature adjustment device 40 also includes a charging module (not shown), and the charging module is used to: determine the charging strategy for the battery based on the temperature detection result, and the charging strategy includes the size of the charging current for the battery requested from the charging device and / or the charging start condition; send a charging request to the charging device according to the charging strategy.

[0189] In the above scheme, the charging strategy determined according to the temperature detection results is compared with using a single charging strategy. This scheme combines the charging strategy determined according to the battery temperature with the temperature adjustment method, which has less impact on the battery, is more intelligent in adjustment, and can save energy consumption.

[0190] In some embodiments, the charging module determines a charging strategy for the battery based on the temperature detection result, including: in response to the detected temperature of the battery being not greater than a preset minimum temperature or not less than a preset maximum temperature, determining that the magnitude of the charging current is the sum of the current required for temperature regulation and the charging current allowed by the battery, and a condition for starting charging is that the temperature of the battery has been adjusted to a preset charging temperature; or, in response to the detected temperature of the battery being greater than a preset minimum temperature and less than a preset maximum temperature, determining that the magnitude of the charging current is the current required for temperature regulation, and a condition for starting charging is that temperature regulation of the battery has begun.

[0191] In the above scheme, when it is detected that the temperature of the battery is too low or too high, charging the battery while the battery temperature is adjusted may not be able to charge the battery well due to the low battery temperature, or, when the battery temperature is too high, it is likely to cause the battery temperature to continue to rise during the charging process. Therefore, the charging condition for starting this scheme is that the battery temperature has been adjusted to a preset charging temperature. In addition, because the battery is generally powered during the temperature adjustment process, the charging current can be the charging current allowed by the battery and the current lost during the temperature adjustment process. If the battery is charged while the temperature is adjusted, in order to reduce overcurrent, the charging current can be less than or equal to the current required for temperature adjustment of the battery.

[0192] In some embodiments, the temperature detection module 42 is also used to: detect the temperature in the passenger compartment of the vehicle based on a wake-up command; the temperature adjustment module 43 is also used to control the air conditioner in the vehicle to adjust the temperature in the passenger compartment in response to the temperature in the passenger compartment being not within a preset temperature range.

[0193] In the above scheme, the temperature in the passenger compartment of the vehicle is detected, and then when the temperature in the passenger compartment is not within the preset temperature range, the air conditioner in the vehicle is controlled to adjust the temperature in the passenger compartment, so that the temperature in the passenger compartment can be maintained within the preset temperature range, providing users with a better riding environment.

[0194] In some embodiments, the temperature adjustment module 43 controls the air conditioner in the vehicle to adjust the temperature in the passenger compartment, including: obtaining the distance between the vehicle and the terminal device; based on the distance, determining a temperature adjustment strategy for the passenger compartment, the adjustment strategy including the start time of the temperature adjustment, the air conditioner power and / or the air outlet gear.

[0195] In the above scheme, by obtaining the distance between the vehicle and the terminal device, and then determining the strategy for adjusting the temperature in the passenger compartment based on the distance, the temperature adjustment method in the passenger compartment is made more flexible, and it is also convenient for the user to ensure that the temperature in the passenger compartment is within a preset temperature range when the user arrives in the vehicle.

[0196] In some embodiments, the temperature adjustment module 43 is further used for: in response to the vehicle detecting that the temperature of the battery has been adjusted to the target temperature, the vehicle sends a preset message to the terminal device to inform the user that the vehicle has completed the temperature adjustment.

[0197] In the above scheme, by detecting that the temperature of the battery has been adjusted to the target temperature, a preset message is sent to the terminal device, which can facilitate the user to understand the battery temperature in the vehicle in a timely manner.

[0198] See also Fig.11 The computer-readable storage medium 60 provided in this embodiment stores program instructions 61 that can be executed by a processor. When the program instructions 61 are executed by the processor, they are used to implement the battery temperature adjustment method in any of the above embodiments.

[0199] In the above scheme, when the charging device detects that the temperature data corresponding to the current temperature of the battery in the vehicle meets the temperature adjustment conditions, it determines whether the vehicle is currently in a preset vehicle use time period. If it is determined that the vehicle is currently in the preset vehicle use time period, a wake-up command can be sent to the vehicle so that the vehicle can perform temperature detection on the battery in the vehicle after receiving the wake-up command, and then adjust the battery temperature according to the result of the temperature detection. Compared with the timed wake-up of the vehicle to detect the battery temperature, this scheme can reduce the number of times the vehicle is woken up and increase the service life of various electrical components in the vehicle.
