Immersion battery cooling involves immersing the battery directly in a coolant and has the advantages of a simple structure

rapid cooling

and better temperature uniformity than conventional indirect liquid cooling

air cooling

and two-phase cooling. This study summarizes the relevant technologies for immersion battery cooling

including screening of immersion liquid

cooling system structure design

and thermal safety

and then analyzes the technical applications of the immersion battery cooling system based on this work. The results show that immersion cooling can rapidly reduce the battery temperature and effectively improve the temperature uniformity of the battery pack. However

this technology requires a high sealing performance of battery modules

and challenges such as leakage and corrosion need to be addressed.
