Abstract: The thermal physical characteristic parameters of the power battery for pure electric vehicle are obtained by experiment and simulation. Then, using finite element simulation software ANSYS, the heating and cooling temperature fields of the battery are simulated and analyzed. The temperature filed distribution is applied to guide the design of the cooling system of the battery pack. Finally, the simulation results of the heating and insulating processes of the battery are used to complete the design of the heating and heat insulation systems, so as to realize the thermal management functions of the battery box. The feasibility of the cooling, heating and heat insulating system designs are verified by experiment.

Key words: vehicle engineering, lithium-ion battery, thermal effect, temperature field distribution, thermal management
