Temperature control of energy storage battery box
In the air thermal management system, conditioned air is used to exchange heat with the lithium-ion battery. Its main advantages are simple structure, low cost and high safety. The liquid as a heat exchange medium has better heat transfer performance than air and is more effective in thermal management.

When inlet flow rate of 3×10-3 L s-1 was applied, the maximum temperature of battery module only reached 28.7 °C at 0.5 C discharge rate. The work of Zhang et al. [24] also revealed that indirect liquid cooling performs better temperature uniformity of energy storage LIBs than air cooling. When 0.5 C charge rate was imposed, liquid .
In this paper, a parametric study is conducted to analyze both the peak temperature and the temperature uniformity of the battery cells. Furthermore, four factors, including setting a new inlet, air inlet location, air inlet, and gap size between the cell and the back wall on the thermal performance of the battery pack, are investigated.
The efficient control and regulation of cooling mechanisms and temperature are of utmost importance to uphold battery performance, prolong battery lifespan, and guarantee the safe operation of EVs. One innovative solution employed in the automotive industry is the use of PCMs for battery thermal management [ 69 ].
Furthermore, it is necessary to design a series of thermal management strategies covering low temperatures (heating), normal temperatures, and high temperatures (heat dissipation). These strategies under different conditions are of great significance to promote battery safety for lithium-ion batteries. 13.
