With the increasing application of the lithium-ion battery, higher requirements are put forward for battery thermal management systems. Compared with other cooling methods, liquid cooling is an efficient cooling method, which can control the maximum temperature and maximum temperature difference of the battery within an acceptable range.
Liquid cooling, often referred to as active cooling, operates through a sophisticated network of channels or pathways integrated within the battery pack, known as the liquid cooling system. The liquid cooling system design facilitates the circulation of specialized coolant fluid.
The liquid-filled battery cooling system is suitable for low ambient temperature conditions and when the battery operates at a moderate discharge rate (2C). Whereas, the battery can operate at higher discharge rates with the maximum temperature maintained within safe limits using a liquid-circulated battery cooling system.
Anisha et al. analyzed liquid cooling methods, namely direct/immersive liquid cooling and indirect liquid cooling, to improve the efficiency of battery thermal management systems in EVs. The liquid cooling method can improve the cooling efficiency up to 3500 times and save energy for the system up to 40% compared to the air-cooling method.
Even in extreme operating conditions such as a thermal runaway, direct liquid cooling has the capability to enable safe battery operation due to the high fire point and phase transition characteristics of coolants.
Wu et al. immersed Li-ion batteries in silicone oil, which is flowing, to improve safety and performance. Direct liquid cooling has the mass and volume integration ratio of the battery pack as high as 91% and 72%, respectively; 1.1 and 1.5 times that of indirect liquid cooling with the same envelope space.
