Unfortunately, there are several thermal disadvantages. For instance, under discharge conditions, a great amount of heat is generated by the redox reactions, and the battery temperature excessively rises . Consequently, it is necessary to develop a battery cooling system to prevent cell damage due to high operative temperature.
Ineffective heat dissipation can heighten stress on battery cells, potentially affecting structural integrity and increasing the risk of thermal runaway. Additionally, excessive heat can compromise the accuracy of cycler testing data, leading to unreliable battery health and performance assessments.
Air cooling, liquid cooling, phase change cooling, and heat pipe cooling are all current battery pack cooling techniques for high temperature operation conditions [7, 8, 9].
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.
Optimal cooling efficiency is achieved with three cooling channel inlets, minimizing the temperature difference across the battery pack. The cornerstone of electric vehicles lies in their power batteries. Operating temperature plays a pivotal role in determining the performance of these batteries [1, 2, 3].
The findings demonstrate that a liquid cooling system with an initial coolant temperature of 15 °C and a flow rate of 2 L/min exhibits superior synergistic performance, effectively enhancing the cooling efficiency of the battery pack.
