[0002] With the development of battery technology, new energy vehicles driven by batteries have also developed. During battery charging, the battery needs to be thermally managed. For example, in the case of low battery temperature, charging is not conducive, so the battery needs to be heated to increase the temperature of the battery; in the case of high battery temperature, the heat generated by charging is likely to affect the safety of the battery, so the battery needs to be cooled to reduce the temperature of the battery.

[0047] With the development of battery technology, new energy vehicles driven by batteries have also developed. During battery charging, the battery needs to be thermally managed. For example, in the case of low battery temperature, charging is not conducive, so the battery needs to be heated to increase the temperature of the battery; in the case of high battery temperature, the heat generated by charging is likely to affect the safety of the battery, so the battery needs to be cooled to reduce the temperature of the battery. However, in the scenario of super-fast charging, the heat generated by charging is more, and the refrigeration power may be difficult to meet the cooling demand, or in the scenario of low ambient temperature, the heating power may be difficult to meet the heating demand, that is, the actual power of the vehicle thermal management is difficult to meet the demand power of the rapid adjustment of the battery temperature.

[0048] In view of the above problems, the embodiments of the present application provide a thermal management method. The method is that the thermal management system determines that the vehicle meets the energy storage trigger condition based on the current temperature and charging information of the battery device, and uses the pre-stored energy of the energy storage device. In this way, in the case of charging the battery device of the vehicle, if the energy provided by the thermal management system of the vehicle does not meet the temperature regulation demand of the battery device, the energy storage device is controlled to use the pre-stored energy for thermal management. It can be seen that in the technical solution of the embodiments of the present application, in the charging scenario, if the energy provided by the thermal management system does not meet the temperature regulation demand of the battery device, the pre-stored energy is used for thermal management. In this way, the thermal management capability can be improved, and the actual demand for regulating the battery temperature can be met as much as possible, so as to maintain the temperature of the battery device in a safe temperature range, thereby improving the charging efficiency and improving the safety and reliability of the battery device and the vehicle.

[0049] The thermal management method provided by the embodiments of the present application can be applied to an application environment as shown in FIG. 1. The application environment can include a new energy vehicle, and the new energy vehicle includes a battery device 10 and a thermal management system 20; wherein the battery device 10 includes battery monomers, a battery management system, etc., and the thermal management system 20 can include an energy manufacturing loop 201, an energy storage device 202, a loop valve 203, a thermal management component 204, a sensor 205, and a thermal management controller 206; the energy manufacturing loop 201 can include but is not limited to an air conditioner compressor of a vehicle-mounted air conditioner; the energy storage device 202 can include but is not limited to an energy storage agent tank, a passenger cabin, and a motor system, etc.; the thermal management component 204 can include but is not limited to an in-vehicle condenser, an evaporator, a liquid cooling condenser, a waste heat recovery plate, a warm air core, a radiator, and a fan, etc., and the evaporator, the in-vehicle condenser, and the warm air core can be arranged on a wind path of the fan. The sensor 205 can include but is not limited to various temperature sensors, voltage sensors, current sensors, etc.

[0050] The thermal management controller 206 is in communication connection with the energy manufacturing loop 201, the energy storage device 202, the loop valve 203, the thermal management component 204, and the sensor 205 respectively, the thermal management controller 206 can acquire the temperature, voltage, current, etc. of the battery device 201 from the sensor 205, and determine the state of charge, input power, output power, etc. of the battery device 201 according to the related data of the battery device 201. The thermal management controller 206 can control the vehicle-mounted air conditioner to refrigerate or heat according to the acquired various data, control the loop valve 203 to conduct the passage between the energy manufacturing loop 201 and the energy storage agent tank and the motor system to store energy, and also can control the loop valve 203 to conduct the passage between the energy storage agent tank and the motor system and the in-vehicle condenser, the evaporator, the liquid cooling condenser, the waste heat recovery plate, and the radiator to perform thermal management. The thermal management controller 206 can also control the working mode of the vehicle-mounted air conditioner, store energy through the passenger cabin, and perform thermal management by using the energy stored in the passenger cabin.

[0051] In some embodiments, the new energy vehicle can further include an in-vehicle infotainment system, and the in-vehicle infotainment system is used to acquire navigation information of the vehicle, destination charging pile information, etc.

[0052] It should be noted that the functions implemented by the thermal management controller 206 are not limited to the above examples, and can be set according to actual conditions. In addition, the thermal management controller 206 described above can include but is not limited to a vehicle controller, a battery management system, etc.

[0053] According to some embodiments of the present application, referring to FIG. 2, a thermal management method is provided, which is taken as an example of being applied to the new energy vehicle in FIG. 1, and can include the following steps:

[0054] In the case of charging the battery device of the vehicle, if the energy provided by the thermal management system of the vehicle does not meet the temperature regulation requirement of the battery device, the energy storage device of the thermal management system is controlled to perform thermal management by using the pre-stored energy.

[0055] In the case of charging the battery device of the vehicle, the battery device needs to be thermally managed to regulate the temperature of the battery device to a safe temperature range. For this purpose, the thermal management system controls the vehicle-mounted air conditioner to perform refrigeration or heating. In the refrigeration process, the thermal management system determines whether the refrigeration capacity of the vehicle-mounted air conditioner meets the cooling requirement of the battery device; in the heating process, the thermal management system determines whether the heating capacity of the vehicle-mounted air conditioner meets the heating requirement of the battery device. If the refrigeration capacity of the vehicle-mounted air conditioner does not meet the cooling requirement of the battery device, or the heating capacity of the vehicle-mounted air conditioner does not meet the heating requirement of the battery device, the energy storage device is controlled to perform thermal management by using the pre-stored energy.

[0056] Before charging the battery device, the thermal management system can obtain the current temperature of the battery device and charging information, and then determine whether the vehicle meets the energy storage triggering condition according to the battery temperature and the charging information. If it is determined that the vehicle meets the energy storage triggering condition, the energy storage device is used to pre-store cold or heat, so that the pre-stored energy can be used for thermal management when the battery device is subsequently charged.

[0057] The charging information can include at least one of charging current, charging time length, charging amount, charging power, driving time, driving distance, average vehicle speed, and charging heat generation.

[0058] In the above embodiments, in the case of charging the battery device of the vehicle, if the energy provided by the thermal management system of the vehicle does not meet the temperature regulation requirement of the battery device, the energy storage device of the thermal management system is controlled to perform thermal management by using the pre-stored energy. In the technical solution of the embodiments of the present application, in the charging scenario, if the energy provided by the thermal management system does not meet the temperature regulation requirement of the battery device, the pre-stored energy is used for thermal management. In this way, the thermal management capability can be improved, and the actual requirement of regulating the battery temperature can be met as much as possible, so that the temperature of the battery device is maintained in a safe temperature range, and the charging efficiency is improved, and the safety and reliability of the battery device and the vehicle are improved.

[0059] According to some embodiments of the present application, the "controlling the energy storage device of the thermal management system to perform thermal management by using the pre-stored energy" in the above embodiments can include the following cases:

[0060] 1) If the temperature of the energy-stored energy storage medium in the thermal management system reaches the heat exchange temperature, the control unit controls the energy storage device to adjust the temperature of the battery device using the energy-stored energy storage medium.

[0061] 2) If the temperature of the energy-stored energy storage medium does not reach the heat exchange temperature, the control unit adjusts the temperature of the thermal management component in the thermal management system using the energy-stored energy storage medium according to the temperature of the energy-stored energy storage medium and the ambient temperature.

[0062] In the embodiments of the present application, the energy storage medium is taken as the circulating cooling water. After the cold storage or heat storage using the circulating cooling water, if the temperature of the cold-stored circulating cooling water reaches the heat exchange temperature at which the battery device can be cooled, the thermal management system makes the circulating cooling water flow through the energy storage device, and the energy storage device cools the circulating cooling water, and then the circulating cooling water flows through the battery device to cool the battery device. If the temperature of the heat-stored circulating cooling water reaches the heat exchange temperature at which the battery device can be heated, the thermal management system makes the circulating cooling water flow through the energy storage device, and the energy storage device heats the circulating cooling water, and then the circulating cooling water flows through the battery device to heat the battery device.

[0063] If the temperature of the cold-stored circulating cooling water is higher than the heat exchange temperature at which the battery device can be cooled, the cold-stored circulating cooling water flows through the thermal management component in the thermal management system, and the cold-stored circulating cooling water is used to cool the thermal management component, thereby improving the refrigeration capacity of the thermal management system. If the temperature of the heat-stored circulating cooling water is lower than the heat exchange temperature at which the battery device can be cooled, the heat-stored circulating cooling water flows through the thermal management component in the thermal management system, and the heat-stored circulating cooling water is used to heat the thermal management component, thereby improving the heating capacity of the thermal management system.

[0064] In the above embodiments, if the temperature of the energy-stored energy storage medium in the thermal management system reaches the heat exchange temperature, the control unit controls the energy storage device to adjust the temperature of the battery device using the energy-stored energy storage medium; if the temperature of the energy-stored energy storage medium does not reach the heat exchange temperature, the control unit adjusts the temperature of the thermal management component in the thermal management system using the energy-stored energy storage medium according to the temperature of the energy-stored energy storage medium and the ambient temperature. In the technical solution of the embodiments of the present application, the energy-stored energy storage medium is used to perform thermal management on the battery device or the thermal management component, which can improve the thermal management capacity of the thermal management system, meet the thermal management requirements of the vehicle as much as possible, and improve the safety of the battery device and the vehicle.

[0065] According to some embodiments of the present application, the thermal management component includes a liquid-cooled condenser. In the above embodiments, "adjusting the temperature of the thermal management component in the thermal management system using the energy-stored energy storage medium according to the temperature of the energy-stored energy storage medium and the ambient temperature" can include the following cases:

[0066] 1) in the case that the temperature of the energy storage medium after the cold storage is lower than the first ambient temperature threshold, the liquid-cooled condenser is cooled by the energy storage medium after the cold storage.

[0067] 2) in the case that the temperature of the energy storage medium after the cold storage is higher than the first ambient temperature threshold, the liquid-cooled condenser is cooled by the radiator in the thermal management system and the energy storage medium after the cold storage.

[0068] In practical applications, the first ambient temperature threshold can be set according to the ambient temperature. For example, the first ambient temperature threshold is the sum of the ambient temperature T and the temperature change amount ΔT1, where ΔT1 can be positive or negative.

[0069] In the case that the temperature of the energy storage medium after the energy storage does not reach the heat exchange temperature, the temperature of the energy storage medium after the energy storage is compared with the first ambient temperature threshold. Taking the energy storage medium as the circulating cooling water and the energy storage mode as the cold storage as an example, if the temperature of the circulating cooling water after the cold storage is lower than the first ambient temperature threshold, it indicates that the temperature of the circulating cooling water is lower than the ambient temperature, and the circulating cooling water after the cold storage is made to flow through the liquid-cooled condenser to cool the liquid-cooled condenser and store energy in the liquid-cooled condenser. If the temperature of the circulating cooling water after the cold storage is higher than the first ambient temperature threshold, it indicates that the ambient temperature is lower than the temperature of the circulating cooling water, and the radiator in the thermal management system can be started to cool the circulating cooling water after the cold storage through the radiator, and then the circulating cooling water after the further cooling is made to flow through the liquid-cooled condenser to cool the liquid-cooled condenser. It can be seen that starting the radiator can further improve the refrigeration capacity of the thermal management system by using the external environment.

[0070] It should be noted that in the case that the temperature of the energy storage medium after the cold storage is equal to the first ambient temperature threshold, the liquid-cooled condenser can be cooled by the energy storage medium after the cold storage according to the actual situation, or the liquid-cooled condenser can be cooled by the radiator in the thermal management system and the energy storage medium after the cold storage.

[0071] In some embodiments, the above-mentioned liquid-cooled condenser can also be replaced by other condensers.

[0072] In the above embodiments, when the temperature of the cold-stored energy storage medium is lower than the first ambient temperature threshold, the cold-stored energy storage medium is used to cool the liquid-cooled condenser; when the temperature of the cold-stored energy storage medium is higher than the first ambient temperature threshold, the radiator in the thermal management system and the cold-stored energy storage medium are used to cool the liquid-cooled condenser. In the technical solution of the embodiments of the present application, when the cold-stored energy storage medium is used to cool the liquid-cooled condenser, it can be determined whether to start the radiator according to the ambient temperature, and when the radiator is started, the external environment can be used to further improve the refrigeration capacity of the thermal management system, so as to meet the actual refrigeration demand as much as possible.

[0073] According to some embodiments of the present application, the thermal management component includes a waste heat recovery plate. In the above embodiments, "adjusting the temperature of the thermal management component in the thermal management system by using the energy-stored energy storage medium according to the temperature of the energy-stored energy storage medium and the ambient temperature" can include the following cases:

[0074] 1) When the temperature of the heat-stored energy storage medium is higher than the second ambient temperature threshold, the heat-stored energy storage medium is used to heat the waste heat recovery plate.

[0075] 2) When the temperature of the heat-stored energy storage medium is lower than the second ambient temperature threshold, the radiator in the thermal management system and the heat-stored energy storage medium are used to heat the waste heat recovery plate.

[0076] In actual application, the second ambient temperature threshold can be set according to the ambient temperature. For example, the second ambient temperature threshold is the sum of the ambient temperature T and the temperature change amount ΔT2, where ΔT2 can be positive or negative. It should be noted that the second ambient temperature threshold can be the same as the first ambient temperature threshold, or different.

[0077] When the temperature of the energy-stored energy storage medium does not reach the heat exchange temperature, the temperature of the energy-stored energy storage medium is compared with the second ambient temperature threshold. Taking the energy storage medium as circulating cooling water and the energy storage mode as heat storage as an example, if the temperature of the heat-stored circulating cooling water is higher than the second ambient temperature threshold, it indicates that the temperature of the circulating cooling water is higher than the ambient temperature, and the heat-stored circulating cooling water is caused to flow through the waste heat recovery plate to heat the waste heat recovery plate. If the temperature of the heat-stored circulating cooling water is lower than the second ambient temperature threshold, it indicates that the ambient temperature is higher than the temperature of the circulating cooling water, and the radiator in the thermal management system can be started to heat the heat-stored circulating cooling water through the radiator, and then the further heated circulating cooling water is caused to flow through the waste heat recovery plate to heat the waste heat recovery plate. It can be seen that starting the radiator can further improve the heating capacity of the thermal management system by using the external environment.

[0078] It should be noted that in the case that the temperature of the heat-stored energy storage medium is equal to the second environmental temperature threshold, the heat-stored energy storage medium can be used to heat the waste heat recovery plate pair according to actual conditions, or the heat-stored energy storage medium and the heat sink can be used to heat the waste heat recovery plate pair.

[0079] In the above embodiments, in the case that the temperature of the heat-stored energy storage medium is higher than the second environmental temperature threshold, the heat-stored energy storage medium is used to heat the waste heat recovery plate pair; in the case that the temperature of the heat-stored energy storage medium is lower than the second environmental temperature threshold, the heat sink and the heat-stored energy storage medium in the thermal management system are used to heat the waste heat recovery plate. In the technical solution of the embodiments of the present application, when the heat-stored energy storage medium is used to heat the waste heat recovery plate, whether the heat sink is started can be determined according to the environmental temperature, and in the case that the heat sink is started, the external environment can be used to further improve the heating capacity of the thermal management system, so as to meet the actual heating demand as much as possible.

[0080] According to some embodiments of the present application, the energy storage device includes an energy storage component; the embodiments of the present application can also include:

[0081] In the case that it is determined that the vehicle meets the energy storage triggering condition according to the current temperature and charging information of the battery device, the loop valve of the thermal management system is controlled to open the passage between the energy generation loop of the thermal management system and the energy storage component, and the energy generated by the energy generation loop is stored by the energy storage component.

[0082] The thermal management system can obtain the current temperature and charging information of the battery device, and determine whether the vehicle meets the energy storage triggering condition according to the current temperature and charging information of the battery; if it is determined that the vehicle meets the energy storage triggering condition, it indicates that the vehicle can store energy in advance to prepare for subsequent improvement of the thermal management capacity of the thermal management system. If it is determined that the vehicle does not meet the energy storage triggering condition, the status quo is maintained and no other processing is performed.

[0083] In the case that it is determined that the vehicle meets the energy storage triggering condition, there are various ways to store energy in advance, one of which is to store energy by using the energy storage component in the vehicle. The above-mentioned energy generation loop can include a vehicle-mounted air conditioner, and the loop valve can include but is not limited to various three-way valves, multi-way valves, etc. In some embodiments, the thermal management system controls the multi-way valve to open the passage between the vehicle-mounted air conditioner and the energy storage component, so that the energy generated by the vehicle-mounted air conditioner can be stored in the energy storage component through the passage for subsequent use.

[0084] In the above embodiment, in the case where it is determined that the vehicle satisfies the energy storage trigger condition according to the current temperature and charging information of the battery device, the circuit valve of the thermal management system is controlled to open the passage between the energy generation circuit of the thermal management system and the energy storage component, and the energy generated by the energy generation circuit is stored by the energy storage component. In the technical solution of the embodiment of the present application, in the case where it is detected that the energy can be stored in advance, the energy is stored by the energy storage component, which facilitates subsequent improvement of the thermal management capability of the thermal management system, so as to meet the actual thermal management demand as much as possible.

[0085] According to some embodiments of the present application, the energy storage component includes an energy storage agent tank and / or a motor system. In the above embodiment, "controlling the circuit valve of the thermal management system to open the passage between the energy generation circuit and the energy storage component, and storing the energy generated by the energy generation circuit by the energy storage component" can include the following manners:

[0086] Manner one: controlling the circuit valve to open the passage between the energy generation circuit and the energy storage agent tank, and storing the energy generated by the energy generation circuit by the energy storage agent in the energy storage agent tank.

[0087] The energy storage agent is placed in the energy storage agent tank, and the energy storage agent can store energy through sensible heat, phase change heat absorption or heat release.

[0088] In the case where the thermal management system is provided with the energy storage agent tank, the thermal management system can control the multi-way valve to open the passage between the vehicle-mounted air conditioner and the energy storage agent tank, and store the energy generated by the vehicle-mounted air conditioner by the energy storage agent in the energy storage agent tank. For example, in the case where the vehicle-mounted air conditioner is in refrigeration, the refrigerant cools the waste heat recovery plate in the thermal management system, the thermal management system controls the multi-way valve to open the passage between the waste heat recovery plate and the energy storage agent tank, and the circulating cooling water flows from the waste heat recovery plate to the energy storage agent tank, so that the energy storage agent in the energy storage agent tank changes phase, thereby realizing pre-cooling. In the case where the energy storage agent tank and the waste heat recovery plate are integrated, the refrigerant directly cools the energy storage agent tank, so that the energy storage agent in the energy storage agent tank changes phase, thereby realizing pre-cooling.

[0089] In the case where the vehicle-mounted air conditioner is in heating, the refrigerant heats the liquid-cooled condenser, the thermal management system controls the multi-way valve to open the passage between the liquid-cooled condenser and the energy storage agent tank, and the circulating cooling water flows from the liquid-cooled condenser to the energy storage agent tank, so that the energy storage agent in the energy storage agent tank changes phase, thereby realizing pre-heating. In the case where the energy storage agent tank and the liquid-cooled condenser are integrated, the refrigerant directly cools the energy storage agent tank, so that the energy storage agent in the energy storage agent tank changes phase, thereby realizing pre-cooling.

[0090] It should be noted that the energy storage agent tank can be integrated with other components in addition to the waste heat recovery plate and the liquid-cooled condenser.

[0091] In the second mode, the control circuit valve guides the passage between the energy generating circuit and the motor system, and the motor system stores the energy generated by the energy generating circuit.

[0092] The thermal management system can also control the multi-way valve to guide the passage between the vehicle air conditioner and the motor system, and the motor system stores the energy generated by the vehicle air conditioner. For example, in the case of cooling by the vehicle air conditioner, the refrigerant cools the waste heat recovery plate in the thermal management system, and the thermal management system controls the multi-way valve to guide the passage between the waste heat recovery plate and the motor system. The circulating cooling water flows from the waste heat recovery plate to the motor system, thereby reducing the temperature of the motor system and achieving pre-cooling. In the case of heating by the vehicle air conditioner, the refrigerant heats the liquid-cooled condenser, and the thermal management system controls the multi-way valve to guide the passage between the liquid-cooled condenser and the motor system. The circulating cooling water flows from the liquid-cooled condenser to the motor system, thereby increasing the temperature of the motor system and achieving pre-heating.

[0093] It should be noted that the energy generated by the energy generating circuit can be stored by one or more of the above-mentioned methods. For example, in the case of the thermal management system provided with an energy storage agent tank, the energy storage method can be to first store the energy generated by the vehicle air conditioner in the energy storage agent tank. If there is still energy left, the energy generated by the vehicle air conditioner can be stored in the motor system. In actual applications, other energy storage components can also be used to store the energy generated by the energy generating circuit.

[0094] In the above-mentioned embodiments, the control circuit valve guides the passage between the energy generating circuit and the energy storage agent tank, and the energy storage agent in the energy storage agent tank stores the energy generated by the energy generating circuit, and / or the control circuit valve guides the passage between the energy generating circuit and the motor system, and the motor system stores the energy generated by the energy generating circuit. In the technical solution of the embodiments of the present application, one or more energy storage components can be used to pre-store energy, which facilitates subsequent cooling or heating using the energy stored in the energy storage components, thereby improving the thermal management capability of the thermal management system and meeting the actual thermal management requirements as much as possible.

[0095] According to some embodiments of the present application, the energy storage device includes a passenger cabin. In the above-mentioned embodiments, "the energy storage device of the thermal management system uses the pre-stored energy for thermal management" can include:

[0096] The circulating mode of the vehicle air conditioner in the thermal management system is adjusted according to the temperature of the passenger cabin after energy storage and the ambient temperature, so as to use the pre-stored energy of the passenger cabin for thermal management.

[0097] In practical applications, in addition to using the energy storage agent tank and the motor system to store energy, the passenger cabin can also be used to store energy. In this way, when performing thermal management, not only can the energy stored in advance by the energy storage agent and the motor system be used for thermal management, but the energy stored in advance by the passenger cabin can also be used for thermal management, thereby further improving the capability of the thermal management system.

[0098] When the passenger cabin is used, the temperature of the passenger cabin after energy storage is compared with the ambient temperature, and the circulation mode of the vehicle-mounted air conditioner is adjusted according to the comparison result. For example, if the temperature of the passenger cabin after energy storage is higher than the ambient temperature, indicating that the ambient temperature is lower than the temperature of the passenger cabin, the circulation mode of the vehicle-mounted air conditioner is adjusted to an external circulation mode, so that the air of the external environment enters the vehicle and participates in thermal management.

[0099] In the above embodiment, the circulation mode of the vehicle-mounted air conditioner in the thermal management system is adjusted according to the temperature of the passenger cabin after energy storage and the ambient temperature, so as to use the energy stored in advance by the passenger cabin for thermal management. In the technical solution of the embodiment of the present application, the energy stored in the passenger cabin is used by adjusting the circulation mode of the vehicle-mounted air conditioner, which can improve the thermal management capability of the thermal management system and improve the.

[0100] According to some embodiments of the present application, the above embodiment of “adjusting the circulation mode of the vehicle-mounted air conditioner in the thermal management system according to the temperature of the passenger cabin after energy storage and the ambient temperature, so as to use the energy stored in advance by the passenger cabin for thermal management” can include the following cases:

[0101] 1) In the case where the temperature of the passenger cabin after energy storage is lower than a third ambient temperature threshold, the circulation mode of the vehicle-mounted air conditioner is adjusted to an internal circulation mode, and the air inside the passenger cabin is used to cool the in-vehicle condenser and / or the heater core of the thermal management system.

[0102] 2) In the case where the temperature of the passenger cabin after energy storage is higher than the third ambient temperature threshold, the circulation mode of the vehicle-mounted air conditioner is adjusted to an external circulation mode, and the air of the external environment is used to cool the in-vehicle condenser and / or the heater core.

[0103] In practical applications, the third ambient temperature threshold can be set according to the ambient temperature. For example, the third ambient temperature threshold is the sum of the ambient temperature T and a temperature change amount ΔT3, where ΔT3 can be positive or negative. It should be noted that the third ambient temperature threshold can be the same as or different from the first ambient temperature threshold and the second ambient temperature threshold.

[0104] If the temperature of the passenger cabin after the cold storage is lower than the third ambient temperature threshold, indicating that the temperature of the passenger cabin after the cold storage is lower than the ambient temperature, the circulation mode of the vehicle air conditioner is adjusted to an internal circulation mode, and the air inside the passenger cabin is used to cool the vehicle condenser and / or the heater core. If the temperature of the passenger cabin after the cold storage is higher than the third ambient temperature threshold, indicating that the ambient temperature is lower than the temperature of the passenger cabin after the cold storage, the circulation mode of the vehicle air conditioner is adjusted to an external circulation mode, air from the external environment is introduced into the vehicle, and the air from the external environment is used to cool the vehicle condenser and / or the heater core.

[0105] It should be noted that if the temperature of the passenger cabin after the cold storage is equal to the third ambient temperature threshold, the circulation mode of the vehicle air conditioner can be adjusted to the internal circulation mode or the external circulation mode according to the actual situation.

[0106] It should be noted that the thermal management component of the vehicle can only include the vehicle condenser or the heater core, or include the vehicle condenser and the heater core. In the case of also providing an air-cooled condenser in the vehicle, the air-cooled condenser can also be thermally managed by the passenger cabin after the cold storage.

[0107] In the above embodiment, in the case that the temperature of the passenger cabin after the cold storage is lower than the third ambient temperature threshold, the circulation mode of the vehicle air conditioner is adjusted to the internal circulation mode, and the vehicle condenser and / or the heater core of the thermal management system are cooled by the air inside the passenger cabin; in the case that the temperature of the passenger cabin after the cold storage is higher than the third ambient temperature threshold, the circulation mode of the vehicle air conditioner is adjusted to the external circulation mode, and the vehicle condenser and / or the heater core are cooled by the air from the external environment. In the technical solution of the embodiment of the application, the circulation mode of the vehicle air conditioner is adjusted to utilize the cold storage of the passenger cabin, which can improve the refrigeration capacity of the thermal management system.

[0108] According to some embodiments of the application, the above embodiment "adjusting the circulation mode of the vehicle air conditioner in the thermal management system according to the temperature of the passenger cabin after the cold storage and the ambient temperature to utilize the energy stored in the passenger cabin in advance for thermal management" can include the following cases:

[0109] 1) In the case that the temperature of the passenger cabin after the cold storage is higher than the fourth ambient temperature threshold, the circulation mode of the vehicle air conditioner is adjusted to the internal circulation mode, and the evaporator of the thermal management system is heated by the air inside the passenger cabin.

[0110] 2) In the case that the temperature of the passenger cabin after the cold storage is lower than the fourth ambient temperature threshold, the circulation mode of the vehicle air conditioner is adjusted to the external circulation mode, and the evaporator is heated by the air from the external environment.

[0111] In actual applications, the fourth ambient temperature threshold can be set according to the ambient temperature. For example, the fourth ambient temperature threshold is the sum of the ambient temperature T and a temperature change amount ΔT4, where ΔT4 can be positive or negative. It should be noted that the fourth ambient temperature threshold can be the same as or different from the first ambient temperature threshold, the second ambient temperature threshold, and the third ambient temperature threshold.

[0112] Exemplarily, the heat storage is performed in an energy storage manner. If the temperature of the passenger compartment after heat storage is higher than the fourth ambient temperature threshold, it is indicated that the temperature of the passenger compartment after heat storage is higher than the ambient temperature, and the circulation mode of the vehicle-mounted air conditioner is adjusted to an internal circulation mode, and the evaporator is heated by using the air inside the passenger compartment. If the temperature of the passenger compartment after heat storage is lower than the fourth ambient temperature threshold, it is indicated that the ambient temperature is higher than the temperature of the passenger compartment after heat storage, and the circulation mode of the vehicle-mounted air conditioner is adjusted to an external circulation mode, and the air of the external environment is introduced into the vehicle, and the evaporator is heated by using the air of the external environment.

[0113] It should be noted that if the temperature of the passenger compartment after heat storage is equal to the fourth ambient temperature threshold, the circulation mode of the vehicle-mounted air conditioner can be adjusted to the internal circulation mode or the external circulation mode according to actual conditions.

[0114] In the above embodiment, in the case where the temperature of the passenger compartment after heat storage is higher than the fourth ambient temperature threshold, the circulation mode of the vehicle-mounted air conditioner is adjusted to the internal circulation mode, and the evaporator of the thermal management system is heated by using the air inside the passenger compartment; in the case where the temperature of the passenger compartment after heat storage is lower than the fourth ambient temperature threshold, the circulation mode of the vehicle-mounted air conditioner is adjusted to the external circulation mode, and the evaporator is heated by using the air of the external environment. In the technical solution of the embodiment of the present application, the circulation mode of the vehicle-mounted air conditioner is adjusted to store energy in the passenger compartment, which can improve the heating capacity of the thermal management system.

[0115] According to some embodiments of the present application, the method can further include: in the case where it is determined that the vehicle satisfies the energy storage triggering condition according to the current temperature and the charging information of the battery device, adjusting the working mode of the vehicle-mounted air conditioner, and storing the energy generated by the thermal management system in the passenger compartment.

[0116] The thermal management system can obtain the current temperature and the charging information of the battery device, and determine whether the vehicle satisfies the energy storage triggering condition according to the current temperature and the charging information of the battery. If it is determined that the vehicle satisfies the energy storage triggering condition, it is indicated that the vehicle can store energy in advance to prepare for subsequent improvement of the capacity of the thermal management system. If it is determined that the vehicle does not satisfy the energy storage triggering condition, the status is maintained, and no other processing is performed.

[0117] In the case where it is determined that the vehicle meets the energy storage triggering condition, there are various ways to pre-store energy, one of which is to store energy in the passenger compartment. For example, in the case of cold accumulation, the working mode of the vehicle air conditioner can be adjusted to the maximum refrigeration mode, and the surplus energy generated by the vehicle air conditioner can be stored in the passenger compartment.

[0118] In the above embodiment, in the case where it is determined that the vehicle meets the energy storage triggering condition according to the current temperature and charging information of the battery device, the working mode of the vehicle air conditioner is adjusted, and the energy generated by the thermal management system is stored in the passenger compartment. In the technical solution of the embodiment of the application, in the case where it is detected that energy can be stored in advance, the energy is stored in the passenger compartment, which facilitates subsequent improvement of the thermal management capability of the thermal management system, so as to meet the actual thermal management demand as much as possible.

[0119] According to some embodiments of the application, with reference to FIG. 3, the above-mentioned embodiment of “adjusting the working mode of the vehicle air conditioner and storing the energy generated by the thermal management system in the passenger compartment” can include the following steps:

[0120] Step 401: controlling the vehicle to output adjustment prompt information.

[0121] When the thermal management system adjusts the working mode of the vehicle air conditioner, the adjustment can be performed with or without sensing. The adjustment with sensing can include: controlling the vehicle to output adjustment prompt information, such as displaying the words “energy storage is about to be performed, whether to adjust the working mode of the vehicle air conditioner” on the vehicle display screen, or playing the voice “energy storage is about to be performed, whether to adjust the working mode of the vehicle air conditioner”.

[0122] It should be noted that the output mode of the adjustment prompt information is not limited to the above examples, and other output modes can also be used in actual applications.

[0123] Step 402: in response to a confirmation operation input by the user for the adjustment prompt information, adjusting the working mode of the vehicle air conditioner to the maximum energy storage mode or operating according to the mode specified by the user, and storing the energy generated by the thermal management system by adjusting the temperature of the passenger compartment through the vehicle air conditioner.

[0124] After the vehicle outputs the adjustment prompt information, the user can input an operation for the adjustment prompt information. If it is determined to adjust the working mode of the vehicle air conditioner, a confirmation operation is input; if it is determined not to adjust the working mode of the vehicle air conditioner, a refusal operation is input.

[0125] The manner of user input operation can be various, such as displaying the words "about to store energy, whether to adjust the working mode of the vehicle-mounted air conditioner" in the vehicle-mounted display screen, and the user can click the confirmation control or the rejection control in the vehicle-mounted display screen. For another example, the vehicle plays the voice "about to store energy, whether to adjust the working mode of the vehicle-mounted air conditioner", and the user can voice reply "confirmation" or "rejection". In actual application, it can also be that the vehicle-mounted display screen displays the adjustment prompt information, and the user voice replies "confirmation" or "rejection"; or the vehicle plays the voice of the adjustment prompt information, and the user clicks the confirmation control or the rejection control in the vehicle-mounted display screen.

[0126] It should be noted that the manner of user input operation is not limited to the above examples, and can be set according to actual conditions.

[0127] After the user inputs the confirmation operation, the vehicle adjusts the working mode of the vehicle-mounted air conditioner to the maximum energy generation mode in response to the confirmation operation, so that the vehicle-mounted air conditioner adjusts the temperature of the passenger compartment, so as to store the energy generated by the thermal management system through the passenger compartment. Taking cold storage as an example, the vehicle adjusts the working mode of the vehicle-mounted air conditioner to the maximum cooling mode in response to the user input confirmation operation, so that the vehicle-mounted air conditioner reduces the temperature of the passenger compartment, so as to pre-store cold. Taking heat storage as an example, the vehicle adjusts the working mode of the vehicle-mounted air conditioner to the maximum heating mode in response to the user input confirmation operation, so that the vehicle-mounted air conditioner increases the temperature of the passenger compartment, so as to pre-store heat.

[0128] In some embodiments, after adjusting the working mode, the air outlet mode of the vehicle-mounted air conditioner can also be adjusted, such as adjusting the face blowing mode to the defrosting mode, the foot blowing mode, etc. It can be understood that adjusting the air outlet mode can improve the comfort of the user and avoid the energy storage reducing the user's use experience.

[0129] In the above embodiments, the vehicle outputs the adjustment prompt information; and in response to the confirmation operation input by the user for the adjustment prompt information, the working mode of the vehicle-mounted air conditioner is adjusted to the maximum energy generation mode, and the energy generated by the thermal management system is stored through the vehicle-mounted air conditioner adjusting the temperature of the passenger compartment. In the technical solution of the embodiments of the present application, the user is prompted to confirm whether to store the energy by the passenger compartment through outputting the adjustment prompt information, so that the use experience of the user can be improved while storing energy.

[0130] According to some embodiments of the present application, the "adjusting the working mode of the vehicle-mounted air conditioner and storing the energy generated by the thermal management system by the passenger compartment" in the above embodiments can include the following cases:

[0131] In a case where the temperature of the passenger cabin is lower than the fifth ambient temperature threshold, the circulation mode of the vehicle air conditioner is adjusted to an internal circulation mode, and cold energy is stored in the passenger cabin; in a case where the temperature of the passenger cabin is higher than the fifth ambient temperature threshold, the circulation mode of the vehicle air conditioner is adjusted to an external circulation mode, and heat is dissipated from the passenger cabin to the external environment, and in a case where the temperature of the passenger cabin is lower than the fifth ambient temperature threshold, the circulation mode of the vehicle air conditioner is adjusted to the internal circulation mode, and cold energy is stored in the passenger cabin.

[0132] In actual applications, the fifth ambient temperature threshold can be set according to the ambient temperature. For example, the fifth ambient temperature threshold is the sum of the ambient temperature T and a temperature change amount ΔT5, where ΔT5 can be positive or negative. It should be noted that the fifth ambient temperature threshold can be the same as or different from the ambient temperature threshold in the above embodiments.

[0133] The above embodiments are exemplarily described in the energy storage mode for cold storage. In a case where the temperature of the passenger cabin is lower than the fifth ambient temperature threshold, it indicates that the temperature of the passenger cabin is lower than the ambient temperature, and the circulation mode of the vehicle air conditioner is adjusted to the internal circulation mode, and cold energy is stored in the passenger cabin. In a case where the temperature of the passenger cabin is higher than the fifth ambient temperature threshold, it indicates that the ambient temperature is lower than the temperature of the passenger cabin, and the circulation mode of the vehicle air conditioner is adjusted to the external circulation mode, and air from the external environment is introduced into the passenger cabin, so as to further reduce the temperature of the passenger cabin, and in a case where the temperature of the passenger cabin is lower than the fifth ambient temperature threshold, the circulation mode of the vehicle air conditioner is adjusted to the internal circulation mode, and cold energy is stored in the passenger cabin.

[0134] In the above embodiments, in a case where the temperature of the passenger cabin is lower than the fifth ambient temperature threshold, the circulation mode of the vehicle air conditioner is adjusted to the internal circulation mode, and cold energy is stored in the passenger cabin; in a case where the temperature of the passenger cabin is higher than the fifth ambient temperature threshold, the circulation mode of the vehicle air conditioner is adjusted to the external circulation mode, and heat is dissipated from the passenger cabin to the external environment, and in a case where the temperature of the passenger cabin is lower than the fifth ambient temperature threshold, the circulation mode of the vehicle air conditioner is adjusted to the internal circulation mode, and cold energy is stored in the passenger cabin. In the technical solution of the embodiments of the present application, cold energy is stored in the passenger cabin by adjusting the circulation mode of the vehicle air conditioner, and the cold storage capacity of the thermal management system can be improved.

[0135] According to some embodiments of the present application, the above-mentioned embodiment of "adjusting the working mode of the vehicle air conditioner, and storing the energy generated by the thermal management system in the passenger cabin" can include the following cases:

[0136] In a case where the temperature of the passenger cabin is higher than the sixth ambient temperature threshold, the circulation mode of the vehicle air conditioner is adjusted to the internal circulation mode, and heat storage is performed by using the passenger cabin; in a case where the temperature of the passenger cabin after heat storage is lower than the sixth ambient temperature threshold, the circulation mode of the vehicle air conditioner is adjusted to the external circulation mode, and the passenger cabin is heated by using the external environment; and in a case where the temperature of the passenger cabin is higher than the sixth ambient temperature threshold, the circulation mode of the vehicle air conditioner is adjusted to the internal circulation mode.

[0137] In actual application, the sixth ambient temperature threshold can be set according to the ambient temperature. For example, the sixth ambient temperature threshold is the sum of the ambient temperature T and the temperature change amount ΔT6, where ΔT6 can be positive or negative. It should be noted that the sixth ambient temperature threshold can be the same as or different from the ambient temperature threshold in the above embodiments.

[0138] The heat storage is exemplarily described in the energy storage mode. In a case where the temperature of the passenger cabin is higher than the sixth ambient temperature threshold, it is indicated that the temperature of the passenger cabin is higher than the ambient temperature, and thus the circulation mode of the vehicle air conditioner is adjusted to the internal circulation mode, and heat storage is performed by using the passenger cabin. In a case where the temperature of the passenger cabin is lower than the sixth ambient temperature threshold, it is indicated that the ambient temperature is higher than the temperature of the passenger cabin, and thus the circulation mode of the vehicle air conditioner is adjusted to the external circulation mode, and the air of the external environment is introduced into the passenger cabin, so as to further increase the temperature of the passenger cabin, and thus heat storage is performed by using the passenger cabin. In a case where the temperature of the passenger cabin is higher than the sixth ambient temperature threshold, the circulation mode of the vehicle air conditioner is adjusted to the internal circulation mode.

[0139] In the above embodiments, in a case where the temperature of the passenger cabin is higher than the sixth ambient temperature threshold, the circulation mode of the vehicle air conditioner is adjusted to the internal circulation mode, and heat storage is performed by using the passenger cabin; in a case where the temperature of the passenger cabin after heat storage is lower than the sixth ambient temperature threshold, the circulation mode of the vehicle air conditioner is adjusted to the external circulation mode, and the passenger cabin is heated by using the external environment; and in a case where the temperature of the passenger cabin is higher than the sixth ambient temperature threshold, the circulation mode of the vehicle air conditioner is adjusted to the internal circulation mode. In the technical solution of the embodiments of the present application, the circulation mode of the vehicle air conditioner is adjusted to perform heat storage by using the passenger cabin, and the heat storage capacity of the thermal management system can be improved.

[0140] According to some embodiments of the present application, with reference to FIG. 4, the above embodiment that “determines whether the vehicle meets the energy storage triggering condition according to the current temperature and the charging information of the battery device” can include the following steps:

[0141] In a case where the current temperature of the battery device does not reach the target temperature, the energy generation demand amount corresponding to the battery device is determined according to the current temperature, the target temperature and the charging information.

[0142] The thermal management system obtains a current temperature of the battery device, and determines whether the current temperature reaches a target temperature. If the target temperature is not reached, a heat generation amount of the charging can be determined according to the charging information, and an energy required for adjusting the temperature of the battery device from the current temperature to the target temperature; then, the energy requirement is determined according to the heat generation amount of the charging and the energy required for adjusting.

[0143] For example, the current temperature of the battery device is T1, the target temperature is T2, the heat required for increasing the temperature of the battery device from T1 to T2 is Q1 if T1 < T2, the heat generation amount of the charging is Q2, and the energy requirement is AQ = Q1-Q2. If T1 > T2, the energy required for decreasing the temperature of the battery device from T1 to T2 is Q3, and the energy requirement is AQ = Q3+Q2.

[0144] In step 502, it is determined that the vehicle meets the energy storage trigger condition if the energy requirement does not reach the upper limit of the energy.

[0145] In the case of refrigeration, if the refrigeration requirement does not reach the upper limit of the refrigeration power, it indicates that there is surplus refrigeration capacity, and in this case, it is determined that the maximum refrigeration power can be used for refrigeration to store the surplus energy, and therefore, it is determined that the vehicle meets the energy storage trigger condition.

[0146] In the case of heating, if the heating requirement does not reach the upper limit of the heating power, it indicates that there is surplus heating capacity, and in this case, it is determined that the maximum heating power can be used for heating to store the surplus heat, and therefore, it is determined that the vehicle meets the energy storage trigger condition.

[0147] It should be noted that during vehicle driving, before vehicle charging, and during vehicle charging, whether the vehicle meets the energy storage trigger condition can be determined according to the current temperature of the battery device and the charging information. If it is determined that the vehicle meets the energy storage trigger condition during vehicle driving, before vehicle charging, and during vehicle charging (initial charging), the energy storage device is used for energy storage.

[0148] In the above embodiment, when the current temperature of the battery device does not reach the target temperature, the energy requirement of the battery device is determined according to the current temperature, the target temperature, and the charging information; and the vehicle meets the energy storage trigger condition if the energy requirement does not reach the upper limit of the energy. In the technical solution of the embodiment of the application, whether the energy storage trigger condition is met is detected by the current temperature of the battery device and the charging information, which can realize early energy storage in a suitable scenario, thereby improving the thermal management capability of the thermal management system and meeting the actual thermal management requirement as much as possible.

[0149] According to some embodiments of the present application, referring to FIG. 5, the above-mentioned embodiment of "determining the energy generation requirement of the battery device according to the current temperature, the target temperature and the charging information" can include the following steps:

[0150] Step 601: determining a target temperature difference according to the current temperature and the target temperature.

[0151] The difference between the current temperature and the target temperature is calculated to obtain the target temperature difference. The target temperature can be determined according to actual conditions. For example, the temperature when the vehicle reaches the target position can be used as the target temperature, the temperature when the battery device is fully charged can be used as the target temperature, or the temperature when the battery device is fully charged after the vehicle reaches the target position can be used as the target temperature.

[0152] It should be noted that the determination method of the target temperature is not limited to the above examples and can be set according to actual conditions.

[0153] Step 602: determining the heat generation amount according to the charging information.

[0154] The charging information includes at least one of the charging current, the charging time length, and the charging amount.

[0155] In the scenario of charging the vehicle, after the vehicle is connected to the charging gun of the charging device, the thermal management system can interact with the charging device to obtain the charging current from the charging device. The thermal management system can determine the charging amount based on the remaining capacity and the rated capacity of the battery device, and determine the charging time length according to the charging current and the charging amount.

[0156] In the scenario of driving the vehicle, the thermal management system can obtain a trip plan and obtain the charging current of the charging device to be used according to the trip plan. Then, the thermal management system determines the charging amount based on the remaining capacity and the rated capacity of the battery device, and determines the charging time length according to the charging current and the charging amount.

[0157] After obtaining the charging information, the heat generation amount can be calculated according to the charging information, for example, the heat generation amount can be calculated according to the charging current.

[0158] It should be noted that the determination method of the charging information and the calculation method of the heat generation amount are not limited to the above examples and can be set according to actual conditions.

[0159] Step 603: determining the energy generation requirement of the battery device according to the target temperature difference and the heat generation amount.

[0160] For example, the target temperature difference determines that the heating amount is Q1, and the heat generation amount of the charging is Q2, so the energy generation requirement ΔQ = Q1-Q2. The target temperature difference determines that the cooling amount is Q3, so the energy generation requirement ΔQ = Q3+Q2.

[0161] In the above embodiment, the target temperature difference is determined according to the current temperature and the target temperature, the heat generation amount is determined according to the charging information, and the energy generation demand of the battery device is determined according to the target temperature difference and the heat generation amount. In the technical solution of the embodiment of the application, the energy generation demand is determined according to the actual situation of the battery device, which facilitates subsequent judgment of whether to generate energy in advance, and provides a basis for improving the heat management capability.

[0162] According to some embodiments of the application, referring to FIG. 6, in the above embodiment, the target temperature difference is determined according to the current temperature and the target temperature, which can include the following steps:

[0163] In step 701, the predicted temperature is determined according to the current temperature and the route plan of the vehicle.

[0164] The heat management system obtains the current temperature of the battery device and the route plan of the vehicle, and can determine the driving mileage or driving time of the vehicle before charging according to the route plan. Then, the predicted temperature of the battery device when the vehicle drives to the target position or when the vehicle is fully charged after charging is obtained by predicting according to the driving mileage and / or driving time and the current temperature of the battery device.

[0165] For example, the current temperature of the battery device is T1, the target temperature is T2, and the predicted temperature T3 of the battery device is obtained by predicting according to T1, T2 and the driving mileage.

[0166] In step 702, the target temperature difference is determined according to the predicted temperature and the target temperature.

[0167] The heat management system can calculate the difference between the predicted temperature and the target temperature that the battery device needs to reach, to obtain the target temperature difference. The target temperature can be set according to the actual situation, for example, the predicted temperature of the battery device is T3, and the target temperature is T2, then the target temperature difference Δt = |T3-T2| can be calculated.

[0168] In the above embodiment, the predicted temperature is determined according to the current temperature and the route plan of the vehicle, and the target temperature difference is determined according to the predicted temperature and the target temperature. In the technical solution of the embodiment of the application, the temperature of the battery device is predicted, which provides a basis for subsequent calculation of the energy generation demand, so that whether to generate energy in advance can be accurately judged.

[0169] It should be understood that although the steps in the above flowcharts are shown in sequence according to the direction of the arrows, the steps are not necessarily executed in the order of the direction of the arrows. Unless otherwise specified herein, the execution of the steps is not strictly limited in sequence, and the steps can be executed in other sequences. Moreover, at least some of the steps in the above flowcharts can include multiple steps or multiple stages, which are not necessarily executed at the same time, but can be executed at different times, and the execution sequence of the steps or stages is not necessarily sequential, but can be alternately or alternately executed with at least part of other steps or steps or stages in other steps.
