Introduction
In air convection cooling, the low thermal conductivity and low specific heat capacity of air prevent it from lowering the maximum temperature and maintaining a uniform temperature in the battery pack when there is a lot of heat . However, battery performance is closely related to temperature .
The research results show that, when the cooler is placed in the flat heat pipe where the module is located, the temperature uniformity of the battery pack is improved, and it is found that adding the cooler can improve the heat dissipation efficiency of the system.
A liquid or air cooling system must manage this elevated heat without compromising safety or performance. Fast charging also demands cooling systems capable of rapidly dissipating generated heat to prevent overheating, a factor that could undermine battery longevity and safety.
Using the low mass flow rates of indirect liquid cooling to control the temperature rise and temperature difference within a battery should be avoided.
