Yusheng Technology's integrated battery liquid-cooling unit combines both cooling and heating functions into a single, compact module. Thanks to its ingeniously designed liquid-cooling circulation system, the unit automatically switches between cooling and heating modes based on BMS operation commands, seamlessly meeting multifunctional thermal management needs for both battery cooling and battery heating—ultimately enabling precise control over battery temperature.

Yusheng Technology's All-in-One Heating and Cooling Model Battery Liquid Cooling Unit Integrating both cooling and heating functional modules, this system features an ingeniously designed liquid-cooling circulation system that automatically switches between cooling, heating, and other operational modes based on BMS commands. Capable of handling multifunctional thermal management needs—simultaneously cooling and heating the battery—the system ensures precise control over battery temperature.

 Working Principle of Integrated Heating and Cooling Battery Liquid-Cooling Units

In cooling mode, the compressor inside the integrated cooling-and-heating battery liquid-cooling unit compresses the refrigerant, raising its temperature and pressure. The high-temperature, high-pressure refrigerant then enters the condenser, where heat is dissipated into the surrounding environment via a cooling fan, causing the refrigerant to cool down and liquefy. Next, the liquid refrigerant passes through an expansion valve, undergoing a throttling process that reduces both its pressure and temperature, before entering the evaporator. Inside the evaporator, the refrigerant absorbs heat from the coolant, significantly lowering its temperature. Finally, the chilled coolant is pumped back into the battery pack by a circulation pump, effectively removing the heat generated by the batteries and ensuring efficient cooling of the battery system.

When the integrated heating-and-cooling battery liquid-cooling unit operates in heating mode, it uses electric heating elements or heat pump technology to warm the coolant. The heated coolant is then circulated back to the battery pack, delivering essential warmth to maintain and elevate the battery temperature—ensuring optimal performance even in cold environments. At the same time, the unit is equipped with high-precision temperature sensors that continuously monitor the battery’s temperature in real time, feeding this data back to the control system. Based on pre-set temperature ranges, the control system intelligently adjusts the cooling or heating output, as well as the flow rate and velocity of the coolant, enabling precise management of the battery temperature and keeping it consistently within the ideal operating range for peak efficiency and safety.
