To study the thermal characteristics of lithium batteries in electric vehicles, a single lithium ion battery under natural convection, forcedair cooling and water cooling conditions were simulated. On this basis, a parallel water-cooling model for battery pack is proposed, and CFD method was used to simulate and analyze the heat characteristics and temperature field distribution of the model at different flow rates, and an optimum flow rate of the cooling water was determined at which the battery pack has the best cooling result and thermal homogeneity corresponding to the given discharge rate.
