[0002] The power battery is a key component of the power system of new energy vehicles. Its performance has a significant impact on the overall performance of new energy vehicles. However, the performance of power batteries is significantly affected by temperature. The heat generated by the power battery itself and the high or low temperature of the environment can cause the power battery temperature to be too low or too high. In turn, this will not only reduce the power battery's available power, resulting in a shorter driving range, but may also affect the safety of the power battery. Currently, when the battery temperature is too high or too low, the power battery temperature is usually regulated by means of air cooling or liquid cooling systems.

[0003] However, the existing power battery core temperature regulation method requires a certain amount of power battery consumption to adjust the power battery core temperature to an appropriate temperature during the initial period of time when the vehicle is parked in an environment with too low or too high a temperature for a period of time in cold winter or hot summer, which causes great damage to the power battery.

[0043] The purpose, features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0044] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0045] With the increasing popularity of new energy vehicles, power batteries are also receiving increasing attention. Power batteries are a key component of new energy vehicle power systems, and their performance significantly impacts the overall performance of new energy vehicles. However, power battery performance is significantly affected by temperature. Heat generated by the power battery itself, as well as high or low ambient temperatures, can cause the power battery temperature to become too low or too high. This, in turn, not only reduces the battery's available power, shortening the vehicle's range, but can also affect the battery's safety.

[0046] Currently, power battery temperature regulation typically involves using an air cooling system or a liquid cooling system when the battery temperature is too high or too low. However, both air and liquid cooling systems require the activation of the vehicle's air conditioning system, heating device, or refrigeration device. If the power battery is continuously temperature-controlled during vehicle use, the core temperature of the power battery can be kept within a normal temperature range without significant damage to the power battery. However, in cold winters or hot summers, if a vehicle has been parked for a period of time in an outdoor environment with excessively low or high temperatures, the core temperature of the power battery may be affected by the environment and become excessively high or low. In this case, starting the vehicle requires first powering the power battery at the excessively high or low temperature to power the vehicle's air conditioning system, heating device, or refrigeration device before the power battery temperature can be regulated. However, existing vehicle air conditioning systems, heating devices, or refrigeration devices used for heating or cooling all consume high power, which in turn causes significant damage to the power battery. Moreover, in very cold winters, when the core temperature of the power battery is below a low temperature threshold, the power battery cannot be discharged or charged, which in turn causes the high-voltage components on the vehicle to be unable to be activated, that is, the vehicle's air-conditioning system, heating device or refrigeration device and other heating and cooling devices cannot operate. In very hot summers, starting the vehicle at high temperature with a power battery is very likely to cause a safety accident.

[0047] In this regard, the present application provides a vehicle suitable data identification method, device, electronic device and storage medium. If it is detected that the temperature of the first regulating liquid in the battery temperature regulating device is not within a preset first suitable temperature range, the second regulating liquid in the thermal insulation storage device is transported to the battery temperature regulating device to adjust the temperature of the first regulating liquid to the preset first suitable temperature range, wherein there is a temperature difference between the second regulating liquid and the first regulating liquid, thereby achieving temperature regulation of the first regulating liquid. Heat transfer is achieved by transferring the heat energy of the second regulating liquid in the thermal insulation storage device to the first regulating liquid, or by taking away the heat energy of the first regulating liquid through the second regulating liquid. The temperature of the first regulating liquid is regulated only by heat transfer, and then the temperature of the core of the power battery is adjusted to the preset second suitable temperature range by transporting the temperature-regulated first regulating liquid to the battery. wherein there is a temperature difference between the first regulating liquid and the battery, thereby achieving temperature regulation of the power battery without starting any heating or cooling device. Since the heat preservation liquid storage device and the battery temperature regulating device are independent of each other, that is, the second regulating liquid in the heat preservation liquid storage device is stored independently of the first regulating liquid for heat preservation, the temperature of the second regulating liquid does not need to be limited by the power battery. Under conditions permitting, the second regulating liquid can be stored as high or as low as possible. Therefore, compared with the first regulating liquid, the second regulating liquid takes longer to change to the ambient temperature and is less affected by the ambient temperature. Therefore, the temperature of the first regulating liquid can be regulated by first storing heat or storing cold and then transferring heat, which is more convenient than starting the heating device or the refrigeration device. As for the temperature regulation method, the present application does not require heating or cooling, and only requires low-voltage components such as low-pressure water pumps. Therefore, even in the cold winter, when the power battery cannot be used to start the vehicle, it can still be powered by a low-voltage battery (such as a lead-acid battery, etc.) to warm up the power battery, which can effectively reduce the loss of the power battery and overcome the technical problem of the prior art that causes large loss to the power battery when the vehicle is started. In addition, even in the very hot summer, when starting the vehicle at high temperature, it can be powered by a low-voltage battery to cool the power battery and avoid safety accidents caused by high temperature of the power battery.

[0048] The present application provides a battery temperature adjustment method. In one embodiment of the battery temperature adjustment method of the present application, referring to Figure 1 The battery temperature regulation method is applied to a battery temperature regulation system of a vehicle, wherein the battery temperature regulation system includes a battery temperature regulation device and a heat preservation liquid storage device that are independent of each other. The battery temperature regulation method includes the following steps:

[0049] Step S10: If it is detected that the temperature of the first regulating liquid in the battery temperature regulating device is not within a preset first suitable temperature range, the second regulating liquid in the heat-insulating liquid storage device is delivered to the battery temperature regulating device to regulate the temperature of the first regulating liquid to within the preset first suitable temperature range, wherein there is a temperature difference between the second regulating liquid and the first regulating liquid;

[0050] In this embodiment, it should be noted that, although the battery temperature regulation method is proposed based on a power battery, the battery temperature regulation method can be applied to power batteries and other non-power batteries, and this embodiment does not impose any limitation on this.

[0051] The core temperature of the power battery and the temperature of the first regulating liquid may both be too high or too low. When the core temperature of the power battery is too high, the temperature of the first regulating liquid can be lowered, and the power battery can be cooled by the first regulating liquid. When the core temperature of the power battery is too low, the first regulating liquid can be heated, and the power battery can be heated by the first regulating liquid. When the temperature of the first regulating liquid is too high, the temperature of the second regulating liquid can be lowered, and the first regulating liquid can be cooled by the second regulating liquid whose temperature is lower than the first regulating liquid. When the temperature of the first regulating liquid is too low, the second regulating liquid can be heated, and the first regulating liquid can be heated by the second regulating liquid whose temperature is higher than the first regulating liquid.

[0052] The vehicle includes at least a power battery and a battery temperature regulation system. The battery temperature regulation method is applied to the battery temperature regulation system of the vehicle. The battery temperature regulation system includes at least a battery temperature regulation device and a thermal insulation liquid storage device. A circuit is formed between the battery temperature regulation device and the thermal insulation liquid storage device through a pipeline. The battery temperature regulation system may also include a low-pressure water pump, a one-way valve, a pipeline, a temperature sensor, a controller, etc.

[0053] The battery temperature regulation device refers to a device that stores a first regulating liquid and regulates the core temperature of a power battery using the first regulating liquid. The battery temperature regulation device includes at least a circulation pipe and a temperature regulation unit. The circulation pipe is connected to the power battery housing. The circulation pipe contains the first regulating liquid, which is transported to the power battery housing through the circulation pipe for heat transfer with the power battery. After the heat transfer, the first regulating liquid is then transported back to the temperature regulation device. The temperature regulation unit forms a circuit connected to the thermal insulation liquid storage device through a pipe, so that the second regulating liquid in the thermal insulation liquid storage device can be transported to the temperature regulation device through the pipe to regulate the temperature of the first regulating liquid in the temperature regulation device. The temperature regulation unit and the circulation pipe may or may not be connected. The battery temperature regulation device may or may not include a first heating unit and / or a first cooling unit, such as an electric heater, a battery radiator, an air conditioning coil, an exhaust gas heat recovery device, etc. The first heating unit is used to heat the first conditioning liquid stored in the battery temperature regulation device when needed, and the cooling unit is used to cool the first conditioning liquid stored in the battery temperature regulation device when needed. If the battery temperature regulation device includes a heating unit and / or a cooling unit, the core temperature of the power battery can be regulated independently of the thermal insulation liquid storage device. If the battery temperature regulation device does not include a heating unit and / or a cooling unit, heat dissipation or heating can be achieved by increasing the surface area of ​​the pipes, providing ventilation pipes, etc., or the temperature of the first conditioning liquid can be regulated by heat transfer between the second conditioning liquid in the thermal insulation liquid storage device and the first conditioning liquid.

[0054] The thermal insulation liquid storage device refers to a container with a certain thermal insulation function, which is used to store a second regulating liquid and regulate the temperature of the second regulating liquid. The thermal insulation liquid storage device achieves its thermal insulation function by blocking conduction, blocking radiation, blocking convection, etc. For example, the inner and outer surfaces of the thermal insulation liquid storage device are coated with a thermal insulation coating such as a ceramic material, a silicide, or a thermal insulation interlayer filled with a polyurethane composite material, etc. The thermal insulation liquid storage device stores the second regulating liquid; the thermal insulation liquid storage device includes a second heating unit and a second cooling unit, such as an electric heater, a battery radiator, an air conditioning coil, an exhaust heat recovery device, etc. The heating unit is used to heat the second regulating liquid stored in the thermal insulation liquid storage device when needed, and the cooling unit is used to cool the second regulating liquid stored in the thermal insulation liquid storage device when needed.

[0055] The preset first suitable temperature range refers to the temperature range in which the first regulating liquid can regulate the core temperature of the power battery, and the preset second suitable temperature range refers to the temperature range that will not adversely affect the performance of the power battery. The preset first suitable temperature range and the preset second suitable temperature range can be determined based on big data or actual test results. In one feasible manner, the preset second suitable temperature range can be set to a certain warning range. For example, when the battery cell temperature is in the range of T1 to T2, it will not have an adverse effect on the battery. The preset second suitable temperature range can be set to T3 to T4, where T3 is less than T1 and T4 is greater than T2. ​​Thus, a certain warning time can be reserved, so that when the core temperature of the power battery is about to be too high or too low, measures can be taken in time to reduce the time that the power battery core temperature exceeds the second suitable temperature range, thereby reducing the loss of the power battery due to excessively high or low temperature. The preset first suitable temperature range may be the same as or different from the preset second suitable temperature range. For example, if the second suitable temperature range of the power battery is greater than T5 and less than T6, then the preset first suitable temperature range may be greater than T5 and less than T6, and may include two temperature ranges greater than T7 and less than T6 and greater than T5 and less than T8, or may include two temperature ranges greater than T7 and less than T9 and greater than T10 and less than T8, wherein T9 is less than T6 and T10 is greater than T5. By setting a certain range difference between the preset first suitable temperature range and the preset second suitable temperature range, the temperature difference between the first regulating liquid and the core temperature may be increased, thereby improving the efficiency of temperature regulation.

[0056] In one practicable manner, the delivery of the first regulating liquid and the second regulating liquid can be achieved by a low-pressure water pump.

[0057] Specifically, during the process of vehicle power-on operation, the temperature of the first regulating liquid in the battery temperature regulating device is continuously detected by a temperature sensor arranged in the battery temperature regulating device. If it is detected that the temperature of the first regulating liquid is not within the preset first suitable temperature range, the second regulating liquid in the thermal insulation storage device is transported to the battery temperature regulating device. There is a temperature difference between the second regulating liquid and the first regulating liquid, so heat can be transferred to the first regulating liquid in the battery temperature regulating device to regulate the temperature of the first regulating liquid to the preset first suitable temperature range. After the second regulating liquid is transported to the battery temperature regulating device, the method of regulating the temperature of the first regulating liquid includes mixing the second regulating liquid with the first regulating liquid, or wrapping it on the outside of the circulation pipe, etc.

[0058] In one feasible manner, during the process of temperature regulating the first regulating liquid, the regulating liquid between the thermal insulation liquid storage device and the temperature regulating unit can circulate through the pipeline, that is, the second regulating liquid is transported from the thermal insulation liquid storage device to the temperature regulating unit through the first pipeline, so that heat transfer occurs between the second regulating liquid and the first regulating liquid. At the same time, the second regulating liquid in the temperature regulating unit, or a mixed solution of the second regulating liquid and the first regulating liquid, can be transported to the thermal insulation liquid storage device, mixed with the second regulating liquid in the thermal insulation liquid storage device, and then heated or cooled to form a new second regulating liquid. The new second regulating liquid can then be transported from the thermal insulation liquid storage device to the temperature regulating unit through the first pipeline, and the cycle is repeated to achieve temperature regulation of the first regulating liquid.

[0059] Optionally, if it is detected that the temperature of the first regulating liquid in the battery temperature regulating device is not within a preset first suitable temperature range, the second regulating liquid in the heat-insulating liquid storage device is delivered to the battery temperature regulating device to regulate the temperature of the first regulating liquid to within the preset first suitable temperature range, wherein the step of there being a temperature difference between the second regulating liquid and the first regulating liquid includes:

[0060] Step S11, when the vehicle is powered on, detecting whether the core temperature of the power battery is within a preset second suitable temperature range;

[0061] In this embodiment, specifically, when it is detected that the vehicle is powered on, the core temperature of the power battery is immediately detected by a temperature sensor provided in the power battery to determine whether the core temperature of the power battery is within a preset second suitable temperature range.

[0062] Step S12: If it is detected that the core temperature of the power battery is not within the preset second suitable temperature range, detecting whether the temperature of the first regulating fluid in the battery temperature regulating device is within the preset first suitable temperature range;

[0063] In this embodiment, specifically, if it is detected that the core temperature of the power battery is not within the preset second suitable temperature range, it means that the power battery needs to be temperature-regulated by the first regulating liquid. Then, it is necessary to first detect the temperature of the first regulating liquid by a temperature sensor provided in the battery temperature regulating device to determine whether the temperature of the first regulating liquid is within the preset first suitable temperature range. It should be noted that when the core temperature of the power battery is not within the preset second suitable temperature range, the core temperature of the power battery is also not within the preset first suitable temperature range. Therefore, when it is detected that the core temperature of the power battery is not within the preset second suitable temperature range, there is a temperature difference between the first regulating liquid and the battery, so temperature regulation can be performed through heat transfer.

[0064] If it is detected that the core temperature of the power battery is within the preset second suitable temperature range, it means that there is no need to adjust the temperature of the power battery through the first regulating liquid. At this time, the step of detecting whether the temperature of the first regulating liquid in the battery temperature regulating device is within the preset first suitable temperature range can still be performed, or the step of detecting whether the core temperature of the power battery is within the preset second suitable temperature range can be returned to. During the subsequent driving process of the vehicle, the core temperature of the power battery is continuously detected.

[0065] Optionally, the preset first suitable temperature range includes a preset suitable low temperature range and a preset suitable high temperature range, the lowest temperature of the preset suitable low temperature range is less than or equal to the lowest temperature of the preset second suitable temperature range, the highest temperature of the preset suitable low temperature range is less than or equal to the highest temperature of the preset second suitable temperature range, the lowest temperature of the preset suitable high temperature range is greater than or equal to the lowest temperature of the preset second suitable temperature range, and the highest temperature of the preset suitable high temperature range is greater than or equal to the highest temperature of the preset second suitable temperature range;

[0066] If it is detected that the core temperature of the power battery is not within the preset second suitable temperature range, detecting whether the temperature of the first regulating fluid in the battery temperature regulating device is within the preset first suitable temperature range includes:

[0067] Step S121, if it is detected that the core temperature of the power battery is higher than the highest temperature of the preset second suitable temperature range, then detecting whether the temperature of the first regulating fluid in the battery temperature regulating device is within the preset suitable low temperature range;

[0068] In this embodiment, it should be noted that the preset first suitable temperature range includes a preset suitable low temperature range and a preset suitable high temperature range, the lowest temperature of the preset suitable low temperature range is less than or equal to the lowest temperature of the preset second suitable temperature range, the highest temperature of the preset suitable low temperature range is less than or equal to the highest temperature of the preset second suitable temperature range, the lowest temperature of the preset suitable high temperature range is greater than or equal to the lowest temperature of the preset second suitable temperature range, and the highest temperature of the preset suitable high temperature range is greater than or equal to the highest temperature of the preset second suitable temperature range. For example, the second suitable temperature range of the power battery is T11-T12, the preset suitable low temperature range may be T11-T12, T13-T12, T11-T14, or T13-T14, wherein T13 is less than T11 and T14 is less than T12, and the preset suitable high temperature range may be T11-T12, T15-T12, T15-T16, or T11-T16, wherein T15 is greater than T11 and T16 is greater than T12.

[0069] Specifically, if it is detected that the core temperature of the power battery is higher than the highest temperature of the preset second suitable temperature range, it means that the power battery needs to be cooled by the first regulating liquid. Therefore, it is detected whether the temperature of the first regulating liquid in the battery temperature regulating device is within the preset suitable low temperature range.

[0070] Step S122: If it is detected that the core temperature of the power battery is lower than the lowest temperature of the preset second suitable temperature range, then detecting whether the temperature of the first regulating fluid in the battery temperature regulating device of the vehicle is within the preset suitable high temperature range;

[0071] In this embodiment, specifically, if it is detected that the core temperature of the power battery is lower than the lowest temperature of the preset second suitable temperature range, it means that the power battery needs to be heated by the first regulating fluid. Therefore, it is detected whether the temperature of the first regulating fluid in the battery temperature regulating device of the vehicle is within the preset suitable high temperature range.

[0072] Step S13: If it is detected that the temperature of the first regulating liquid in the battery temperature regulating device is not within the preset first suitable temperature range, the second regulating liquid in the heat-insulating liquid storage device is delivered to the battery temperature regulating device to regulate the temperature of the first regulating liquid to the preset first suitable temperature range, wherein there is a temperature difference between the second regulating liquid and the first regulating liquid;

[0073] In this embodiment, specifically, if it is detected that the temperature of the first regulating liquid in the battery temperature regulating device is within a preset first suitable temperature range, it means that the first regulating liquid at this time can regulate the temperature of the battery cell of the power battery, and then the step of directly delivering the temperature-regulated first regulating liquid to the battery to regulate the core temperature of the power battery to a preset second suitable temperature range can be executed.

[0074] If the temperature of the first regulating liquid in the battery temperature regulating device is detected to be within the preset first suitable temperature range, it indicates that the temperature of the first regulating liquid may also be too high or too low due to environmental influences. In this case, even if the first regulating liquid is delivered to the power battery, the temperature of the power battery cells cannot be adjusted to the suitable temperature range. In this case, the second regulating liquid in the thermal insulation storage device can be delivered to the battery temperature regulating device to adjust the temperature of the first regulating liquid to the preset first suitable temperature range. Since the thermal insulation storage device and the battery temperature regulating device are independent of each other, that is, the second regulating liquid in the thermal insulation storage device is stored and insulated independently of the first regulating liquid, the temperature of the second regulating liquid is not limited by the power battery. If conditions permit, the second regulating liquid can be stored at a temperature as high or as low as possible. The second regulating liquid can also be insulated by providing an insulation layer or other means. Therefore, compared to the first regulating liquid, the second regulating liquid takes longer to reach the ambient temperature and is less affected by the ambient temperature. Therefore, when the first regulating liquid is affected by the ambient temperature and exceeds the first suitable temperature range, the second regulating liquid may still be able to adjust the temperature of the first regulating liquid to the first suitable temperature range.

[0075] Optionally, if it is detected that the temperature of the first regulating liquid in the battery temperature regulating device is not within a preset first suitable temperature range, the step of delivering the second regulating liquid in the heat-insulating liquid storage device to the battery temperature regulating device to regulate the temperature of the first regulating liquid to within the preset first suitable temperature range includes:

[0076] Step S131: If it is detected that the temperature of the first regulating liquid in the battery temperature regulating device is not within the preset suitable low temperature range, the second regulating liquid in the heat-insulating liquid storage device is delivered to the battery temperature regulating device to regulate the temperature of the first regulating liquid to the preset suitable low temperature range, wherein the temperature of the second regulating liquid is lower than the temperature of the first regulating liquid;

[0077] In this embodiment, specifically, if it is detected that the temperature of the first regulating liquid in the battery temperature regulating device is not within the preset suitable low temperature range, the second regulating liquid stored in the thermal insulation liquid storage device and having a temperature lower than that of the first regulating liquid is transported to the battery temperature regulating device, and the temperature of the first regulating liquid is adjusted to the preset suitable low temperature range by heat transfer.

[0078] In step S132, if it is detected that the temperature of the first regulating liquid in the battery temperature regulating device is not within the preset suitable high temperature range, the second regulating liquid in the thermal insulation liquid storage device is transported to the battery temperature regulating device to adjust the temperature of the first regulating liquid to the preset suitable high temperature range, wherein the temperature of the second regulating liquid is greater than the temperature of the first regulating liquid.

[0079] In this embodiment, specifically, if it is detected that the temperature of the first regulating liquid in the battery temperature regulating device is not within the preset suitable high temperature range, the second regulating liquid stored in the thermal insulation liquid storage device and having a temperature higher than that of the first regulating liquid is transported to the battery temperature regulating device, and the temperature of the first regulating liquid is adjusted to the preset suitable high temperature range by heat transfer.

[0080] In this embodiment, after the vehicle is powered off, all temperature control devices cease to operate. At this time, the entire vehicle, including the power battery, the first regulating fluid, and the second regulating fluid, will be affected by the external ambient temperature and may heat up or cool down. Since the second regulating fluid is stored in an independent thermal insulation storage device, the temperature range of the second regulating fluid itself is wider than that of the power battery and the first regulating fluid. During normal operation of the vehicle, it can fully store heat or cold, and the temperature drop rate of the second regulating fluid is slower. Therefore, under the influence of the same ambient temperature, the second regulating fluid can maintain its adjustability for a longer period of time. For example, when the ambient temperature is low (for example, 5°C, 0°C or even lower), the temperature of the first regulating liquid can be heated to a first higher temperature range. However, since the first regulating liquid will be directly delivered to the power battery, in order to avoid the core temperature of the power battery being too high or locally too high, the first higher temperature range cannot be too high. For example, it can be heated to 20°C, 30°C, 40°C, 50°C, etc., but cannot be heated to 80°C, 90°C, 100°C or even higher. However, the second regulating liquid is independently stored in a thermal insulation liquid storage device. Since it is not directly connected to the power battery, it can be heated to 80°C, 90°C, 100°C or even higher. Under the influence of the same ambient temperature, the second regulating liquid can maintain a high temperature for a longer time, and then the temperature can be adjusted by the second regulating liquid after the core temperature of the power battery and the temperature of the first regulating liquid are both reduced to an appropriate temperature range. Especially during cold winters or hot summers, when a vehicle is parked for a period of time in an outdoor environment with excessively low or high temperatures, the power battery core temperature may become excessively high or low due to environmental influences. Using the power battery at this time can cause damage to the battery and may even prevent the vehicle from starting properly or lead to a safety accident. By immediately detecting the power battery cell temperature and the temperature of the first conditioning fluid when the vehicle is powered on, and promptly delivering the second conditioning fluid via a low-pressure water pump when the appropriate temperatures are detected, the power battery temperature is regulated while consuming less power, reducing power battery damage and overcoming the technical problem of the prior art of causing significant power battery damage during vehicle startup.

[0081] In step S20 , the temperature-adjusted first conditioning liquid is delivered to the battery to adjust the core temperature of the power battery to a preset second suitable temperature range, wherein there is a temperature difference between the first conditioning liquid and the battery.

[0082] In this embodiment, specifically, after the second conditioning liquid transfers heat with the first conditioning liquid to adjust the temperature of the first conditioning liquid, the first conditioning liquid is transported to the housing of the power battery. Due to the temperature difference between the first conditioning liquid and the battery, the first conditioning liquid can transfer heat to the power battery to adjust the temperature of the power battery, thereby adjusting the core temperature of the power battery to a preset second suitable temperature range. It should be noted that the process of the second conditioning liquid adjusting the temperature of the first conditioning liquid can be performed simultaneously with the process of the first conditioning liquid adjusting the temperature of the power battery.

[0083] In this embodiment, if it is detected that the temperature of the first regulating liquid in the battery temperature regulating device is not within the preset first suitable temperature range, the second regulating liquid in the thermal insulation storage device is transported to the battery temperature regulating device to adjust the temperature of the first regulating liquid to the preset first suitable temperature range, wherein there is a temperature difference between the second regulating liquid and the first regulating liquid, thereby achieving temperature regulation of the first regulating liquid, and achieving heat transfer by transferring heat energy of the second regulating liquid in the thermal insulation storage device to the first regulating liquid, or by taking away the heat energy of the first regulating liquid through the second regulating liquid, thereby achieving temperature regulation of the first regulating liquid only by heat transfer, and then by transporting the temperature-regulated first regulating liquid to the battery, the core temperature of the power battery is adjusted to the preset second suitable temperature range, wherein there is a temperature difference between the first regulating liquid and the battery, thereby achieving temperature regulation of the power battery without starting any heating or cooling device. Since the thermal insulation liquid storage device and the battery temperature regulation device are independent of each other, that is, the second regulating liquid in the thermal insulation liquid storage device is stored and insulated independently of the first regulating liquid, the temperature of the second regulating liquid does not need to be limited by the power battery, and a second regulating liquid with a higher temperature or a lower temperature can be stored. Therefore, compared with the first regulating liquid, the time required for the second regulating liquid temperature to change to the ambient temperature is longer, so the temperature of the first regulating liquid can be regulated by heat transfer. Compared with the method of starting the heating device or the refrigeration device to regulate the temperature, the present application has a smaller demand on the power battery when the vehicle is started, which can effectively reduce the loss of the power battery, and overcome the technical problem of the prior art that causes large loss to the power battery when the vehicle is started.

[0084] Further, refer to Figure 4Based on the above embodiment of the present application, in another embodiment of the present application, the same or similar contents as the above embodiment can be referred to the above description and will not be repeated hereafter. On this basis, the preset first suitable temperature range includes a preset suitable low temperature range and a preset suitable high temperature range. Before the step of transferring the second regulating liquid in the heat-insulating liquid storage device to the battery temperature regulating device and regulating the temperature of the first regulating liquid to the preset first suitable temperature range, the following steps are further included:

[0085] Step A10: if it is detected that the ambient temperature is within the preset heat storage temperature range, the temperature of the second regulating fluid is increased to above the lowest temperature of the preset suitable high temperature range;

[0086] In this embodiment, while the vehicle is powered on, the temperature of the external environment in which the vehicle is located is continuously detected by a temperature sensor. If the ambient temperature is detected to be within a preset heat storage temperature range, the temperature of the second regulating fluid is raised to above the lowest temperature of the preset suitable high temperature range. The preset heat storage temperature range refers to the range of ambient temperatures that may cause the power battery temperature to be too low, and can be specifically determined based on big data or actual test results. When the ambient temperature is within the preset heat storage temperature range, heat can be stored through the second regulating fluid. The manner of raising the temperature of the second regulating fluid to above the lowest temperature of the preset suitable high temperature range includes heating the second regulating fluid with the help of the heating function after the air-conditioning system is turned on; hybrid vehicles using waste heat from the engine exhaust pipe to heat the second regulating fluid; when the vehicle is fully charged and cannot be charged anymore, recovering energy for heating, etc.

[0087] Since the second regulating liquid is stored in an independent thermal insulation liquid storage device, it does not need to be restricted by the power battery. Therefore, under the premise of ensuring that the thermal insulation liquid storage device can effectively keep warm and is safe, the second regulating liquid is heated and adjusted to the highest possible temperature, such as 80°C, 90°C, 100°C or even higher.

[0088] In one practicable manner, if it is detected that the ambient temperature is within the preset heat storage temperature range, the step of raising the temperature of the second regulating fluid to above the lowest temperature of the preset suitable high temperature range includes:

[0089] In step A11, if it is detected that the ambient temperature is within the preset heat storage temperature range, the first regulating liquid is heated to the preset first regulating temperature, and the temperature of the second regulating liquid is increased to above the lowest temperature of the preset suitable high temperature range.

[0090] In this embodiment, specifically, during the power-on operation of the vehicle, the temperature of the external environment of the vehicle is continuously detected by a temperature sensor. If the ambient temperature is detected to be within a preset heat storage temperature range, the temperature of the first regulating fluid can be preferentially adjusted, and the first regulating fluid can be heated to the preset first regulating temperature, so that when the power battery needs to be temperature-regulated, the temperature of the power battery can be timely adjusted by the first regulating fluid. Simultaneously or after the first regulating fluid is heated to the preset first regulating temperature, the temperature of the second regulating fluid is raised to above the lowest temperature of the preset suitable high temperature range.

[0091] Step A20: If it is detected that the ambient temperature is within the preset cold storage temperature range, the temperature of the second regulating fluid is lowered to below the highest temperature of the preset suitable low temperature range.

[0092] In this embodiment, if it is detected that the ambient temperature is within the preset cold storage temperature range, the temperature of the second regulating fluid is lowered to below the maximum temperature of the preset suitable low temperature range, wherein the preset cold storage temperature range refers to the range of ambient temperatures that may cause the power battery temperature to be too high, and can be specifically determined based on big data or actual test results. When the ambient temperature is within the preset cold storage temperature range, cold storage can be performed using the second regulating fluid. The method of lowering the temperature of the second regulating fluid to below the maximum temperature of the preset suitable low temperature range includes cooling the second regulating fluid with the help of the cooling function after the air-conditioning system is turned on; when the vehicle is fully charged and cannot be charged anymore, recovering energy for cooling, etc.

[0093] Since the second regulating liquid is stored in an independent heat-insulating liquid storage device, it does not need to be restricted by the power battery. Therefore, under the premise of ensuring that the second regulating liquid is in liquid state and that the heat-insulating liquid storage device can effectively keep warm and is safe, the second regulating liquid is cooled and adjusted to the lowest possible temperature, such as 10°C, 5°C, 0°C or even lower.

[0094] In one practicable manner, if it is detected that the ambient temperature is within the preset cold storage temperature range, the step of lowering the temperature of the second regulating fluid to below the maximum temperature of the preset suitable low temperature range includes:

[0095] In step A21 , if it is detected that the ambient temperature is within the preset cold storage temperature range, the first regulating fluid is cooled to a preset second regulating temperature, and the temperature of the second regulating fluid is cooled to below the highest temperature of the preset suitable low temperature range.

[0096] In this embodiment, specifically, if it is detected that the ambient temperature is within the preset cold storage temperature range, the temperature of the first regulating liquid can be preferentially adjusted, and the first regulating liquid can be cooled to the preset second regulating temperature, so that when the power battery needs to be temperature adjusted, the power battery can be temperature-regulated in a timely manner through the first regulating liquid, and simultaneously or after the first regulating liquid is cooled to the preset second regulating temperature, the temperature of the second regulating liquid can be reduced to below the highest temperature of the preset suitable low temperature range.

[0097] In this embodiment, since the second regulating liquid is stored in an independent thermal insulation liquid storage device, it does not need to be restricted by the power battery. Therefore, when the ambient temperature is within the preset heat storage temperature range, the vehicle's various heat generation or energy can be fully utilized to heat the second regulating liquid, and heat is stored in the thermal insulation liquid storage device. When the ambient temperature is within the preset cold storage temperature range, the vehicle's various cold sources or energy can be fully utilized to cool the second regulating liquid, and cold is stored in the thermal insulation liquid storage device. Therefore, when the first regulating liquid cannot effectively control the temperature of the power battery, the second regulating liquid and the power battery are quickly and timely regulated by the second regulating liquid, thereby reducing the loss of the power battery caused by the appropriate temperature, and overcoming the technical problem of the prior art that causes large loss to the power battery when the vehicle is started.

[0098] Furthermore, the present invention also provides a battery temperature regulation system, referring to Figure 5 In the first embodiment of the battery temperature regulation system, the battery temperature regulation system includes: a battery temperature regulation device and a heat preservation liquid storage device 20, wherein,

[0099] The battery temperature adjustment device includes a circulation pipe 12 and a temperature adjustment unit 11. The circulation pipe 12 is connected to the box of the power battery 30. The circulation pipe 12 is filled with a first regulating liquid. The temperature adjustment unit 11 forms a circuit connected to the heat-insulating liquid storage device 20 through a pipe 40.

[0100] The heat-insulating liquid storage device 20 is used to store the second regulating liquid and regulate the temperature of the second regulating liquid. When it is detected that the ambient temperature is greater than the preset first temperature, the temperature of the second regulating liquid is lowered to below the temperature of the first regulating liquid. When it is detected that the ambient temperature is lower than the preset first temperature, the temperature of the second regulating liquid is raised to above the temperature of the first regulating liquid.

[0101] In this embodiment, specifically, the battery temperature regulation system is applied to a vehicle, and the vehicle refers to a new energy vehicle. The vehicle includes a power battery 30 and a battery temperature regulation system. The battery temperature regulation system includes at least a battery temperature regulation device and a thermal insulation liquid storage device 20. A circuit is formed between the battery temperature regulation device and the thermal insulation liquid storage device 20 through a pipeline. The battery temperature regulation system may also include a low-pressure water pump, a one-way valve, a pipeline, a temperature sensor, a controller, etc.

[0102] The battery temperature regulation device is a device that stores a first regulating liquid and regulates the core temperature of the power battery 30 using the first regulating liquid. The battery temperature regulation device includes at least a circulation conduit 12 and a temperature regulation unit 11. The circulation conduit 12 is connected to the housing of the power battery 30. The circulation conduit 12 contains the first regulating liquid, which is transported to the housing of the power battery 30 through the circulation conduit 12 for heat transfer with the power battery 30. After the heat transfer, the first regulating liquid is then transported back to the temperature regulation device. The temperature regulation unit 11 forms a circuit connected to the thermal insulation liquid storage device 20 via a conduit 40, allowing the second regulating liquid in the thermal insulation liquid storage device 20 to be transported to the temperature regulation device via the conduit 40 to regulate the temperature of the first regulating liquid in the temperature regulation device. The temperature regulation unit 11 and the circulation conduit 12 may or may not be connected. The battery temperature regulation device may or may not include a first heating unit and / or a first cooling unit, such as an electric heater, a battery radiator, or an air conditioning coil. The first heating unit is used to heat the first conditioning fluid stored in the battery temperature regulation device when needed, and the cooling unit is used to cool the first conditioning fluid stored in the battery temperature regulation device when needed. If the battery temperature regulation device includes a heating unit and / or a cooling unit, the core temperature of the power battery 30 can be regulated independently of the thermal insulation liquid storage device 20. If the battery temperature regulation device does not include a heating unit and / or a cooling unit, heat dissipation or heating can be achieved by increasing the surface area of ​​the pipe 40, providing a ventilation duct, or by regulating the temperature of the first conditioning fluid through heat transfer between the second conditioning fluid in the thermal insulation liquid storage device 20 and the first conditioning fluid.

[0103] The thermal insulation liquid storage device 20 is a container with a certain thermal insulation function, which is used to store the second regulating liquid and regulate the temperature of the second regulating liquid. The thermal insulation liquid storage device 20 achieves its thermal insulation function by blocking conduction, blocking radiation, blocking convection, etc. For example, the inner and outer surfaces of the thermal insulation liquid storage device 20 are coated with a thermal insulation coating such as a ceramic material, a silicide, etc., or a thermal insulation interlayer filled with a polyurethane composite material is provided. The thermal insulation liquid storage device 20 stores the second regulating liquid; the thermal insulation liquid storage device 20 includes a second heating unit and a second cooling unit, such as an electric heater, a battery radiator, an air conditioning coil, etc. The heating unit is used to heat the second regulating liquid stored in the thermal insulation liquid storage device 20 when needed, and the cooling unit is used to cool the second regulating liquid stored in the thermal insulation liquid storage device 20 when needed.

[0104] The preset first suitable temperature range refers to the temperature range of the first regulating fluid when the first regulating fluid has difficulty regulating the core temperature of the power battery 30. The preset second suitable temperature range refers to the temperature range that may adversely affect the performance of the power battery. Both the preset first suitable temperature range and the preset second suitable temperature range can be determined based on big data or actual test results. The preset first suitable temperature range can be greater than or equal to the preset second suitable temperature range. For example, if the second suitable temperature range of the power battery is less than T1 or greater than T2, then the preset first suitable temperature range can be less than T1 or greater than T2, or less than T3 or greater than T4, where T3 is less than T1 and T4 is greater than T2. ​​By setting a certain range difference between the preset first suitable temperature range and the preset second suitable temperature range, a certain warning time can be reserved. This allows for early warning when the core temperature of the power battery is about to become too high or too low to reduce the time the core temperature of the power battery is within the second suitable temperature range, thereby reducing power battery losses caused by excessively high or low temperatures.

[0105] In one practicable manner, the delivery of the first regulating liquid and the second regulating liquid can be achieved by a low-pressure water pump.

[0106] Optionally, refer to Figure 2 In the second embodiment of the battery temperature regulation system, the circulation pipeline includes a liquid inlet pipeline 121 and a liquid outlet pipeline 122, the liquid inlet pipeline 121 is connected to the liquid inlet 111 of the temperature regulation unit 11, and the liquid outlet pipeline 122 is connected to the liquid outlet 112 of the temperature regulation unit 11;

[0107] The temperature regulating unit 11 is used to mix the first regulating liquid input from the liquid inlet pipe 121 and the second regulating liquid input from the heat-insulating liquid storage device 20 to obtain a new first regulating liquid 50 , and output the new first regulating liquid to the liquid outlet pipe 122 .

[0108] Optionally, refer to Figure 3 , in a third embodiment of the battery temperature regulation system, the circulation pipe passes through the temperature regulation unit;

[0109] The temperature regulating unit 11 is used to receive the second regulating liquid 60 input from the heat-insulating liquid storage device 20 and output the second regulating liquid 60 to the heat-insulating liquid storage device 20 after heat exchange with the first regulating liquid in the circulation pipe 12 .

[0110] In one practicable manner, the flow direction of the first regulating liquid in the circulation pipe is opposite to the flow direction of the second regulating liquid in the temperature regulating unit. Figure 3 In the battery temperature adjustment system shown, if the first adjustment liquid in the circulation pipe 12 flows from left to right, the second adjustment liquid in the temperature adjustment unit 11 flows from right to left, and vice versa.

[0111] Optionally, the shell of the thermal insulation liquid storage device includes a first thermal insulation layer and a second thermal insulation layer, the first thermal insulation layer and the second thermal insulation layer are filled with a polyurethane composite material, the surfaces of the first thermal insulation layer and the second thermal insulation layer are coated with at least one layer of thermal insulation material, and the thermal insulation material includes ceramic material and silicate.
