Abstract
Unprecedented opportunities for the development of pure electric vehicle industry have been brought by constantly growing issues of energy crisis and environmental pollution. The performance of electric vehicles is decisively influenced by the battery pack, which is the only power source of pure electric vehicles. However, the efficiency of battery drops under the conditions of ultra-high, ultra-low, and uneven temperature distribution inside the battery pack. To improve the performance, reliability and safety of the lithium-ion battery pack, the negative effect of non-uniform heat dissipation should be alleviated. In this paper, the thermal model of the lithium-ion battery is described. A 3D battery pack model is built. Several structural factors that affect the heat dissipation, including the selection of the location and quantity of the battery pack outlet, the arrangement mode of cells, and the distance between cells and wall, are simulated by utilizing the finite element analysis (FEA) and discussed. According to the simulation result, the factors influencing the battery temperature field and the influence law is summarized.
