Research progress in thermal management system of lithium-ion battery on liquid cooling
Lithium-ion battery is widely used in electric vehicles and energy storage because of its excellent electrochemical charac-teristics,but its performance is greatly affected by working tem-perature.Therefore,designing the reasonable and effective ther-mal management system is a key technology to promote the devel-opment of lithium-ion battery.This paper summarizes the com-mon thermal management systems,including the research status,advantages and disadvantages of air cooling,phase change mate-rial cooling,heat pipe cooling and liquid cooling.Especially it in-troduces the current optimization methods of liquid cooling tech-nology for the direct contact liquid cooling and indirect contact liq-uid cooling.For the limitations of a single thermal management system,it also analyzes the thermal management research status of liquid cooling combined with other methods from the perspec-tive of coupled thermal management system.Finally,the direc-tion of comprehensive optimization and intelligent control for liq-uid cooling management system is proposed,and the liquid cool-ing combining with the passive heat dissipation and linking of the battery management system has great development potential.
