Abstract

The thermal characteristics of the power battery for pure electric vehicle are analyzed by means of theoretical analysis and numerical simulation. Taking a soft pack of lithium-ion battery as the research object, the structure of liquid cooling board of power battery is optimized. The results show that increasing the number of runners can improve the heat dissipation effect of the cooling board. Increasing the cross-section area of runner can improve the heat dissipation effect of cooling board on high temperature area. Increasing the inlet velocity of cooling liquid can further reduce the temperature difference of the battery. The optimum conditions for heat dissipation are as follows, the number of runners is nine, the cross-section area of runner increased by 0.15 mm², the inlet velocity of cooling liquid is 1.25 m/s.
