Abstract As external package of a lithium ion battery is made of multi-layer composite film, solid support is not available for the flexible package battery. During a high-rate charge/discharge cycle, the batteries will generate a lot of heat and gas inevitably produced by the side-reactions, which leads to the expansion and deformation of the batteries. In this paper, heat sink was designed to cool and fasten the battery. The design of the thermal structure is a combination of heat sink and air cooling. A numerical simulation of battery module based on CFD theory is conducted. The result shows that the maximum temperature rise of the battery pack is 5 ℃ and the maximum temperature difference in the pack is 2 ℃.
