Abstract

At present, the power of electric vehicle mainly relies on li-ion battery module. The temperature field of lithium-ion power battery pack assembly is an important factor which affects the security and reliability of EV when the vehicle is running [1,2]. In this paper, by simulating the typical discharge condition of Li-ion battery module, it is realized that the detailed temperature field and air flow field of battery pack assembly. According to the results of thermal analysis, li-ion battery module layout can be improved, and the high-temperature region of battery pack assembly can be found clearly
