With the rapid development of new energy vehicles,as one of the core of"three electrics",the heat dissipation problem of new energy vehicle power batteries has attracted more and more attention from designers.This paper reviews the five main power battery heat dissipation technologies-convection heat dissipation,air cooling heat dissipation,liquid cooling heat dissipation,heat pipe cooling and phase change material cooling,and analyzes and compares their principles,advantages and disadvantages and applications,which provides certain reference value for the development of new energy vehicle power battery heat dissipation technology.
