These cooling methods typically require complex systems constructed with cooling channels, cold plates, and pipes to remove heat from the battery pack indirectly. Immersion cooling operates deeper within the battery pack, integrating the cooling system at the individual cell level. XING uses advanced, high-nickel cathode, cylindrical lithium ...
According to the type of contact, liquid-cooled battery cooling systems can be divided into direct and indirect liquid cooling systems. Some scholars have studied the indirect liquid cooling technology [[22], [23], [24]] of energy storage batteries and confirmed its high efficiency and minor temperature difference relative to air cooling. The ...
