The power battery thermal management system mainly consists of a temperature monitoring device, a cooling system, a heating system, and a control unit. The temperature monitoring device is responsible for monitoring the battery's temperature changes in real time; the cooling system includes various methods such as air cooling, liquid cooling, and direct cooling to effectively dissipate heat and reduce the battery temperature when it is too high; the heating system includes methods such as electric heating film, PTC heating, and liquid heating to heat the battery in low-temperature environments to ensure the battery's normal operation; the control unit is responsible for receiving temperature information and controlling the operating status of the cooling and heating systems according to the actual situation.

 

 

Different methods can be selected independently for battery cooling and heating. However, as vehicles become increasingly integrated, higher demands are being placed on vehicle thermal management systems. As a result, thermal management systems that can both cool and heat the battery have emerged. Some vehicles have even developed highly integrated thermal management systems using heat pump air conditioning, organically combining the vehicle cooling system, the power battery cooling/heating system, and the passenger compartment cooling and heating system.
