[0034] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0035] The following is for reference. Figures 1-7 The present invention describes a thermal management system 100 according to an embodiment of the present invention, which can be applied to a vehicle.

[0036] Combination Figures 1-7 As shown, the thermal management system 100 according to this utility model mainly includes: a refrigerant circulation loop 10, a battery 20, a heater core 301, and a cooling tank 40. The refrigerant circulation loop 10 includes a compressor 101, a condenser 102, and an evaporator 103 that are interconnected. The refrigerant in the refrigerant circulation loop 10 can absorb and release heat through a series of physical state changes, thereby indirectly heating or cooling the passenger compartment 50 and the battery 20.

[0037] Specifically, the refrigerant enters the compressor 101 in the form of a low-pressure gas. The compressor 101 compresses the refrigerant into a high-temperature, high-pressure gas and discharges it. The high-temperature, high-pressure gaseous refrigerant enters the condenser 102, where it releases heat, gradually cools, and condenses into a high-pressure liquid. The high-pressure liquid refrigerant passes through the expansion valve 902, causing a sudden pressure drop. As the pressure decreases, part of the refrigerant evaporates, and the temperature drops, forming a low-temperature, low-pressure liquid refrigerant. This low-temperature, low-pressure refrigerant enters the evaporator 103, absorbing heat from the surrounding environment. After absorbing sufficient heat, the refrigerant evaporates into a low-temperature, low-pressure gas, ready to be drawn back into the compressor 101, completing one cycle. Throughout the cycle, the refrigerant effectively transfers heat through the transformation between gaseous and liquid states, thereby achieving the effect of heating or cooling.

[0038] Furthermore, the water outlet of battery 20 is selectively connected to the water inlet of condenser 102, and the water outlet of condenser 102 is selectively connected to the water inlet of battery 20. This creates a water circulation loop between battery 20 and condenser 102. Condenser 102 can absorb heat from refrigerant circulation loop 10 to cool the refrigerant in refrigerant circulation loop 10, and then use water as a medium to transfer heat to battery 20 through the water circulation loop, thereby heating battery 20.

[0039] Furthermore, the heater core 301 is connected to the passenger compartment 50 of the vehicle. The outlet of the condenser 102 and the inlet of the heater core 301 are selectively connected. This creates a water circulation loop between the heater core 301 and the condenser 102. The condenser 102 absorbs heat from the refrigerant circulation loop 10 to cool the refrigerant in the refrigerant circulation loop 10. Then, using water as a medium, the heat is transferred to the heater core 301 through the water circulation loop, and then transferred to the passenger compartment 50 through the heater core 301, thereby heating the passenger compartment 50.

[0040] Furthermore, the battery 20 is connected in parallel with the heater core 301 and selectively connected to the condenser 102 in the refrigerant circulation loop 10. This allows for indirect heating of both the passenger compartment 50 and the battery 20, thereby improving system efficiency, saving energy and reducing emissions, and lowering costs.

[0041] Furthermore, the outlet of the cooling tank 40 is selectively connected to the inlet of the evaporator 103, and the outlet of the cooling tank 40 is selectively connected to the outlet of the evaporator 103. This creates a water circulation loop between the cooling tank 40 and the evaporator 103. The evaporator 103 absorbs heat from the surrounding environment, causing the refrigerant in the refrigerant circulation loop 10 to vaporize, thereby cooling the environment around the evaporator 103. The cooled water is then transferred through the water circulation loop to the cooling tank 40 for storage, accommodating the cooled water in the thermal management system 100. Simultaneously, the cooling tank 40 allows for easy replenishment of cooling water, ensuring sufficient water within the thermal management system 100 for effective heat exchange. Additionally, the cooling tank 40 provides a convenient location for adding or checking the water medium in the thermal management system 100.

[0042] Therefore, by selectively controlling the connections between components such as the cooling tank 40, condenser 102, evaporator 103, heater core 301, passenger compartment 50, and battery 20, the cooling and heating of the passenger compartment 50 and battery 20 can be indirectly achieved. This not only reduces the need for additional heat and cold sources and the number of parts, but also improves system efficiency, increases energy utilization, reduces energy consumption for cooling and heating, and helps to save energy and reduce emissions, lower costs, and alleviate range anxiety.

[0043] It should be noted that in this utility model, the refrigerant circulation loop 10 uses a new type of refrigerant R290 to effectively improve the working efficiency and performance of the thermal management system 100.

[0044] In some embodiments of this utility model, the thermal management system 100 is provided with an overflow tank 906 that is selectively connected to components such as the cooling tank 40, the electronic control assembly 70, the condenser 102, the heater core 301, and the battery 20. The overflow tank 906 can be used to store excess coolant, add or replace the coolant in the thermal management system 100, and also help maintain the stability of the pressure in the thermal management system 100, thereby improving the cooling efficiency of the components connected to the overflow tank 906 and achieving rapid cooling.

[0045] In some embodiments of this utility model, a three-way valve 901 is provided in the thermal management system 100 to regulate the water flow path, so that multiple different water circulation loops can exist in the thermal management system 100, so that the thermal management system 100 can have multiple different working modes.

[0046] In some embodiments of this utility model, the thermal management system 100 is provided with a one-way valve 903. The one-way valve 903 is mainly used to restrict the flow direction of the refrigerant, prevent the refrigerant from flowing in reverse at the one-way valve 903, prevent refrigerant backflow, and improve the working performance of the thermal management system 100.

[0047] In some embodiments of this utility model, temperature sensors 904 are provided at the motor 60 and the heater core 301 in the thermal management system 100 to monitor the temperature of the motor 60 and the heater core 301. When the temperature is abnormal, the temperature of the motor 60 and the heater core 301 can be adjusted in time, which helps to keep the motor 60 and the heater core 301 working within a certain temperature range and helps to improve the working performance of the thermal management system 100.

[0048] In some embodiments of this utility model, a pressure / temperature sensor 905 is provided in the refrigerant circulation loop 10 of the thermal management system 100. The pressure / temperature sensor 905 can simultaneously measure two physical quantities: pressure and temperature, and can be used to monitor the working status of the refrigerant circulation loop 10, which helps to optimize the working performance of the refrigerant circulation loop 10.

[0049] In some embodiments of this utility model, a gas-liquid separator 907 is provided at the water inlet of the evaporator 103 in the refrigerant circulation loop 10, which can separate the gas and liquid coming out of the evaporator 103 in the refrigerant circulation loop 10, ensuring that only gaseous refrigerant enters the compressor 101, which helps to improve the working efficiency of the compressor 101.

[0050] Combination Figure 1As shown, the water outlet and water inlet of battery 20 are selectively connected. Specifically, when the water outlet and water inlet of battery 20 are connected, a closed water circulation loop can be selectively formed in the thermal management system 100, allowing water to be used as a medium to transfer heat. When the water temperature is higher than the temperature of battery 20, heat can be transferred to battery 20, thus heating battery 20; when the water temperature is lower than the temperature of battery 20, heat dissipated by battery 20 can be absorbed, thus cooling battery 20. Therefore, heating and cooling of battery 20 can be achieved through the water circulation loop. Furthermore, connecting the water outlet and water inlet of battery 20 helps to balance the internal pressure of the battery 20 system.

[0051] Furthermore, if the thermal management system 100 malfunctions or requires maintenance, the outlet and inlet of the battery 20 can be selectively disconnected to reduce the impact of system malfunctions, facilitate troubleshooting, and quickly locate the fault point. This can improve the reliability and safety of the thermal management system 100. In addition, it can also facilitate the replacement of water or other liquids in the pipeline.

[0052] Furthermore, by selectively connecting the water outlet of battery 20 to the water inlet of battery 20, the flow path of water in the pipeline can be dynamically adjusted according to specific conditions or needs. It is possible to select whether to heat or cool battery 20 according to its actual working state, which can help improve heat exchange efficiency and extend the service life of battery 20.

[0053] Combination Figure 1 As shown, the thermal management system 100 also includes a motor 60, with its outlet and inlet selectively connected. Specifically, when the outlet and inlet of the motor 60 are connected, a closed water circulation loop can be selectively formed in the thermal management system 100, allowing water to be used as a medium to transfer heat. When the motor 60 temperature is too high or needs to be maintained within a specific range, the inlet of the motor 60 can be connected to the outlet of the condenser, and the outlet of the motor 60 can be connected to the inlet of the cooling tank 40. When the water flowing through the motor 60 is cooler than the motor 60, it can absorb the heat dissipated by the motor 60, thus cooling the motor 60. When it is necessary to prevent condensation in the motor 60 or for other specific needs, higher-temperature water can be transferred to the motor 60 through the water circulation loop to transfer heat to the motor 60, thus raising the temperature of the motor 60. Therefore, the water circulation loop can achieve cooling and heating of the motor 60. In addition, connecting the water outlet and water inlet of the motor 60 helps to balance the internal pressure of the motor 60 system.

[0054] Furthermore, if the thermal management system 100 malfunctions or requires maintenance, the outlet and inlet of the motor 60 can be selectively disconnected to reduce the impact of system malfunctions, facilitate troubleshooting, and quickly locate the fault point. This can improve the reliability and safety of the thermal management system 100. In addition, it can also facilitate the replacement of water or other liquids in the pipeline.

[0055] Furthermore, by selectively connecting the outlet of motor 60 to the inlet of motor 60, the water flow path can be dynamically adjusted according to specific conditions or needs. Depending on the actual working state of motor 60, it is possible to select whether to cool, heat up, or store heat, which can help improve heat exchange efficiency and extend the service life of motor 60.

[0056] Combination Figure 1 As shown, the thermal management system 100 also includes an electronic control assembly 70. The inlet of the electronic control assembly 70 is connected to the outlet of the motor 60, and the outlet of the electronic control assembly 70 is selectively connected to the inlet of the motor 60. Specifically, the electronic control assembly 70 is responsible for monitoring and adjusting the working status of each component in the system to ensure the stable operation and high efficiency of the thermal management system 100. By connecting the inlet of the electronic control assembly 70 to the outlet of the motor 60, and selectively connecting the outlet of the electronic control assembly 70 to the inlet of the motor 60, the water flowing through the motor 60 can exchange heat with the electronic control assembly 70 when it reaches the electronic control assembly 70. This allows the temperature of the electronic control assembly 70 to approach the temperature of the motor 60, enabling the motor 60 and the electronic control assembly 70 to work together in a favorable temperature environment, thus optimizing the stability of the thermal management system 100 when the motor 60 and the electronic control assembly 70 are engaged in operation.

[0057] Furthermore, the three-way valve 901 can be used to make the electronic control assembly 70 form a water circulation loop only with the motor 60, thereby enabling the motor 60 to store heat.

[0058] Combination Figure 1 As shown, the condenser 102 includes an air-cooled condenser 1021 and a water-cooled condenser 1022. The compressor 101 is selectively connected to one of the air-cooled condenser 1021 and the water-cooled condenser 1022. The outlet of the water-cooled condenser 1022 is selectively connected to the inlet of the heater core 301, and the outlet of the heater core 301 is selectively connected to the inlet of the water-cooled condenser 1022.

[0059] Specifically, the air-cooled condenser 1021 uses a fan to blow air through the condenser tubes, carrying away heat from the refrigerant. As the refrigerant flows within the condenser tubes, it releases heat to the surrounding air, causing the refrigerant to condense from a gaseous state to a liquid state. The water-cooled condenser 1022 utilizes water flowing through the outside of the condenser tubes, exchanging heat with the water flow to carry away heat from the refrigerant, thus causing the refrigerant to condense from a gaseous state to a liquid state. The temperature of the water flowing outside the condenser tubes is lower than the temperature of the refrigerant inside the condenser tubes. The condensation process of the air-cooled condenser 1021 does not require a water circulation system, resulting in a simple structure and low cost. The water-cooled condenser 1022 offers good cooling performance and is unaffected by changes in outside air temperature, maintaining a relatively stable cooling efficiency. If heat transfer using the heat dissipated by the refrigerant is required, the compressor 101 is selectively connected to the water-cooled condenser 1022; otherwise, the compressor 101 is selectively connected to the air-cooled condenser 1021.

[0060] Furthermore, the outlet of the water-cooled condenser 1022 and the inlet of the heater core 301 are selectively connected. When the compressor 101 is selectively connected to the water-cooled condenser 1022, the water flow after absorbing heat in the water-cooled condenser 1022 can be guided to the heater core 301. The heater core 301 is connected to the passenger compartment 50, and the air in the passenger compartment 50 is heated through the heater core 301. This not only recovers the heat that might have been dissipated by the refrigerant to cool the water-cooled condenser 1022, but also heats the air in the passenger compartment 50 through the heated water flow in the water circulation loop. This reduces the need for additional heat sources, improves energy efficiency, saves energy and protects the environment, reduces the operating cost of the thermal management system 100, and improves passenger comfort. In addition, the selective connection between the water-cooled condenser 1022 and the heater core 301 helps to improve the responsiveness of the thermal management system 100, so as to adjust the water flow path in a timely manner according to system needs and passenger needs.

[0061] Combination Figure 1As shown, the thermal management system 100 also includes a cold air core 302, which is connected to the passenger compartment 50 of the vehicle. The water inlet of the cold air core 302 is selectively connected to the water outlet of the evaporator 103, and the water outlet of the cold air core 302 is selectively connected to the water inlet of the evaporator 103. Specifically, by selectively connecting the inlet of the cold air core 302 to the outlet of the evaporator 103, and vice versa, the water cooled by the evaporator 103 can be guided to the cold air core 302. The cold air core 302 is connected to the passenger compartment 50, cooling the air inside the passenger compartment 50. This not only provides heat to the evaporator 103 through the water circulation loop but also cools the air inside the passenger compartment 50 through the cooled water flow within the water circulation loop. This reduces the need for additional refrigeration equipment, improves energy efficiency, saves energy and is environmentally friendly, reduces the operating cost of the thermal management system 100, and enhances passenger comfort. Furthermore, although the evaporator 103 is primarily responsible for cooling, the discharged cooling water still contains some heat, which can be reused in certain situations, such as providing gentle heating or preheating to the interior.

[0062] Furthermore, the selective connection between the evaporator 103 and the cold air core 302 helps to improve the responsiveness of the thermal management system 100, so as to adjust the water flow path in a timely manner according to system requirements and passenger needs.

[0063] Combination Figure 1 As shown, the outlet of battery 20 is selectively connected to the inlet of evaporator 103, the outlet of evaporator 103 is selectively connected to the inlet of battery 20, and the outlet of evaporator 103 is selectively connected to the inlet of cooling core 302, while the outlet of cooling core 302 is selectively connected to the inlet of evaporator 103. This configuration allows for parallel connection of battery 20 and cooling core 302, enabling water cooled by evaporator 103 to flow simultaneously to both battery 20 and cooling core 302. Alternatively, evaporator 103 can be selectively connected to either battery 20 or cooling core 302, cooling only that one. The evaporator 103 can be selectively connected to the battery 20 and / or the cooling core 302 according to the vehicle's operating status and the passengers' needs, thereby achieving cooling of the battery 20 and / or the cooling core 302.

[0064] Combination Figure 1As shown, the thermal management system 100 also includes an electronic control assembly 70, the water inlet of the electronic control assembly 70 being connected to the water outlet of the motor 60, the water outlet of the battery 20 being selectively connected to the water inlet of the motor 60, and the water outlet of the battery 20 being selectively connected to the water inlet of the cooling tank 40, the water outlet of the electronic control assembly 70 being selectively connected to the water inlet of the cooling tank 40, and the water outlet of the cooling tank 40 being selectively connected to the water inlet of the battery 20.

[0065] Specifically, by connecting the water inlet of the electronic control assembly 70 to the water outlet of the motor 60, the electronic control assembly 70 and the motor 60 are connected in series. In this way, when the water flowing through the motor 60 reaches the electronic control assembly 70, it can exchange heat with the electronic control assembly 70. This allows the temperature of the electronic control assembly 70 to approach the temperature of the motor 60, enabling the motor 60 and the electronic control assembly 70 to work together in a good temperature environment. This can optimize the stability of the thermal management system 100 when the motor 60 and the electronic control assembly 70 are working together.

[0066] Furthermore, the water outlet of battery 20 is selectively connected to the water inlet of motor 60, which helps to balance the temperature between motor 60, electronic control assembly 70 and battery 20, prevent local overheating, and improve vehicle stability.

[0067] Furthermore, by selectively connecting the outlet of battery 20 to the inlet of cooling tank 40, selectively connecting the outlet of electronic control assembly 70 to the inlet of cooling tank 40, and selectively connecting the outlet of cooling tank 40 to the inlet of battery 20, the cooling tank 40 can be used to cool battery 20, motor 60, and electronic control assembly 70 through heat exchange.

[0068] Combination Figure 1 As shown, the thermal management system 100 also includes a water pump 80, which is connected to the battery 20. Specifically, the water pump 80 is a mechanical device used to transport liquids, which can convert mechanical energy into the pressure energy or kinetic energy of the liquid, enabling the liquid to flow in the pipeline system. By connecting the water pump 80 to the battery 20, the water pump 80 can drive the flow of water in the pipeline on the side of the battery 20, which can help to cool and heat the battery 20, improve the efficiency of cooling or heating the battery 20, prevent the battery 20 from overheating or overcooling and affecting its working performance, and enable the battery 20 to operate within a certain temperature range.

[0069] The following is combined Figures 2-7 The working mode of the thermal management system 100 according to an embodiment of the present invention is described.

[0070] Combination Figure 2As shown, the working mode of the thermal management system 100 in this embodiment of the present invention is: refrigeration of the crew cabin 50.

[0071] In the refrigerant circulation loop 10, the compressor 101 is connected to the air-cooled condenser 1021, so that the air-cooled condenser 1021 participates in the work, while the water-cooled condenser 1022 does not participate in the work.

[0072] In the water circulation loop, the evaporator 103 and the cold air core 302 are connected by controlling the opening and closing of the valves in each three-way valve 901.

[0073] In this working mode, the water in the evaporator 103 pipe dissipates heat and cools down. When the cooled water reaches the cold air core 302 through the water circulation loop, it can exchange heat with the cold air core 302 to achieve the cooling of the cold air core 302. The cold air core 302 is connected to the passenger compartment 50, and thus the passenger compartment 50 can be cooled through the cold air core 302.

[0074] Combination Figure 3 As shown, the second working mode of the thermal management system 100 in this embodiment of the present invention is: refrigeration of the passenger compartment 50 and active cooling of the battery 20.

[0075] In the refrigerant circulation loop 10, the compressor 101 is connected to the air-cooled condenser 1021, so that the air-cooled condenser 1021 participates in the work, while the water-cooled condenser 1022 does not participate in the work.

[0076] In the water circulation loop, by controlling the opening and closing of the valves in each three-way valve 901, the battery 20 and the cold air core 302 are connected in parallel, and the evaporator 103, the cold air core 302 and the battery 20 are connected in a corresponding manner.

[0077] In this working mode, the water in the evaporator 103 pipe dissipates heat and cools down. When the cooled water reaches the cold air core 302 and the battery 20 through the water circulation loop, it can exchange heat with the cold air core 302 and the battery 20 to achieve cooling of the cold air core 302 and the battery 20. The cold air core 302 is connected to the passenger compartment 50, and thus the passenger compartment 50 can be cooled through the cold air core 302.

[0078] Combination Figure 4 As shown, the thermal management system 100 of this utility model embodiment operates in three modes: refrigeration of the passenger compartment 50, passive cooling of the battery 20, and heat dissipation of the motor 60.

[0079] In the refrigerant circulation loop 10, the compressor 101 is connected to the air-cooled condenser 1021, so that the air-cooled condenser 1021 participates in the work, while the water-cooled condenser 1022 does not participate in the work.

[0080] In the water circulation loop, by controlling the opening and closing of the valves in each three-way valve 901, the cooling tank 40, motor 60, electronic control assembly 70 and battery 20 are connected accordingly.

[0081] In this operating mode, the water in the evaporator 103 pipe dissipates heat and cools down. When the cooled water reaches the cold air core 302 through the water circulation loop, it can exchange heat with the cold air core 302 to achieve cooling of the cold air core 302. The cold air core 302 is connected to the passenger compartment 50, and thus the passenger compartment 50 can be cooled through the cold air core 302. When the water in the cooling tank 40 flows to the motor 60 and the battery 20, it can exchange heat with the motor 60 and the battery 20 to achieve heat dissipation of the motor 60 and cooling of the battery 20.

[0082] Combination Figure 5 As shown, the fourth working mode of the thermal management system 100 in this embodiment of the present invention is: heating of the crew cabin 50.

[0083] In the refrigerant circulation loop 10, the compressor 101 is connected to the water-cooled condenser 1022, so that the water-cooled condenser 1022 participates in the operation. At this time, the air-cooled condenser 1021 does not participate in the operation. In addition, the expansion valve 902 between the water inlet of the compressor 101 and the water inlet of the evaporator 103 is in the conducting state.

[0084] In the water circulation loop, the evaporator 103 is connected to the cooling tank 40 by controlling the opening and closing of the valves in each three-way valve 901, and the water-cooled condenser 1022 is connected to the warm air core 301.

[0085] In this working mode, the water in the water-cooled condenser 1022 pipe absorbs heat and rises in temperature. When the heated water reaches the heater core 301 through the water circulation loop, it can exchange heat with the heater core 301 to achieve heating of the heater core 301. The heater core 301 is connected to the passenger compartment 50, and thus the passenger compartment 50 can be heated through the heater core 301.

[0086] Combination Figure 6 As shown, the fifth working mode of the thermal management system 100 in this embodiment of the present invention is: heating of the crew cabin 50 and heating of the battery 20.

[0087] In the refrigerant circulation loop 10, the compressor 101 is connected to the water-cooled condenser 1022, so that the water-cooled condenser 1022 participates in the operation. At this time, the air-cooled condenser 1021 does not participate in the operation. In addition, the expansion valve 902 between the water inlet of the compressor 101 and the water inlet of the evaporator 103 is in the conducting state.

[0088] In the water circulation loop, the evaporator 103 and the cooling tank 40 are connected by controlling the opening and closing of the valves in each three-way valve 901. At the same time, the heater core 301 is connected in parallel with the battery 20, and the water-cooled condenser 1022, the heater core 301 and the battery 20 are connected in a corresponding manner.

[0089] In this operating mode, the water in the water-cooled condenser 1022 pipe absorbs heat and rises in temperature. When the heated water reaches the heater core 301 and battery 20 through the water circulation loop, it can exchange heat with the heater core 301 and battery 20 to achieve heating of the heater core 301 and battery 20. The heater core 301 is connected to the passenger compartment 50, and thus the passenger compartment 50 can be heated through the heater core 301.

[0090] Combination Figure 7 As shown, the working mode of the thermal management system 100 in this embodiment of the present invention is as follows: heating of the passenger compartment 50, heating of the battery 20, and heat storage of the motor 60.

[0091] In the refrigerant circulation loop 10, the compressor 101 is connected to the water-cooled condenser 1022, so that the water-cooled condenser 1022 participates in the operation. At this time, the air-cooled condenser 1021 does not participate in the operation. In addition, the expansion valve 902 between the water inlet of the compressor 101 and the water inlet of the evaporator 103 is in the conducting state.

[0092] In the water circulation loop, the evaporator 103 is connected to the cooling tank 40 by controlling the opening and closing of the valves in each three-way valve 901. At the same time, the water-cooled condenser 1022 is connected to the heater core 301, the motor 60 is connected to the electronic control assembly 70, and the battery 20 is connected to the one-way valve 903 through the water pump 80 to achieve the circulation loop.

[0093] In this operating mode, the water in the water-cooled condenser 1022 pipe absorbs heat and rises in temperature. When the heated water reaches the heater core 301 through the water circulation loop, it can exchange heat with the heater core 301 to heat the heater core 301. The heater core 301 is connected to the passenger compartment 50, and thus the passenger compartment 50 can be heated through the heater core 301. After the motor 60 starts running, it heats up and can exchange heat with the water flow in the motor 60 side pipe. Through the combined action of the motor 60 and the water circulation loop on the motor 60 side, the motor 60 can store heat within an appropriate range. The battery 20 side pipe is not connected to the external water flow with temperature changes. The water flow in the battery 20 side pipe is self-circulated through the water pump 80, one-way valve 903 and three-way valve 901. The water flow in the pipe can exchange heat with the battery 20 to maintain the temperature of the battery 20 within a certain temperature range, thus achieving the insulation of the battery 20. In addition, the evaporator 103 is connected to the cooling tank 40, which can store the excess water after it has been cooled by the evaporator 103.

[0094] The vehicle according to this utility model mainly includes the aforementioned thermal management system 100. Specifically, because the thermal management system 100 has a more energy-efficient structure and good working performance, applying the thermal management system 100 to a vehicle can not only optimize the vehicle's working performance, but also reduce the vehicle's cooling and heating energy consumption, save energy and reduce emissions, lower costs, and alleviate range anxiety.
