Abstract：In recent years,significant breakthroughs have been achieved in aspects such as the safety,charging time,cruising range,and service life of lithium-ion power batteries.This has greatly promoted the development of new energy vehicles,and these breakthroughs are inseparable from the innovation of lithium-ion power battery thermal management technology.Under high and low temperature conditions,the thermal management system cools or heats the lithium-ion power battery,enabling it to charge and discharge within an appropriate temperature range.This not only eliminates the heat accumulation generated during the charging and discharging process of the lithium-ion power battery,but also prevents the safety risks caused by lithium plating during charging at low temperatures.At the same time,it can shorten the charging time,increase the cruising range,and extend the service life.This paper reviews various thermal management technologies for lithium-ion power batteries,including air cooling,liquid cooling,heat transfer using phase-change materials,etc.,and analyzes their advantages and disadvantages,providing a reference for future research on thermal management technologies.
