新能源汽车浸没式锂离子电池冷却技术研究进展
Research Progress of Immersed Cooling Technology for Lithium-ion Batteries in New Energy Vehicles
摘要
Abstract
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.关键词
