This study proposed a composite thermal management solution for cylindrical lithium-ion battery modules that combined forced air-cooling with direct liquid-cooling. The transformer oil was used as the liquid cooling medium. The optimum liquid-cooling structure and fan position were determined.
The liquid and forced air flow are suggested to be in the same direction. The safety, lifespan and performance of lithium-ion battery are closely related to its working temperature. A large amount of heat will be generated inside the battery during working. Therefore, a thermal management system is necessary to cool down the battery.
The model agrees well with experimental results in terms of both pressure drop and temperature variation. Furthermore, the operating parameters of the liquid cooling system are comprehensively investigated under extreme conditions, with a 35 °C ambient temperature and a 5 C discharge rate based on the optimal flow pattern.
Specifically, for the liquid cooling system, the location near the fluid inlet correlates to the lowest battery temperature, whereas the location of the fluid outlet corresponds to a higher battery temperature.
In this study, a liquid-cooling management system of a Li-ion battery (LIB) pack (Ni-Co-Mn, NCM) is established by CFD simulation. The effects of liquid-cooling plate connections, coolant inlet temperature, and ambient temperature on thermal performance of battery pack are studied under different layouts of the liquid-cooling plate.
