Abstract: When the electric vehicle is working normally, the heat released by the battery causes the battery pack to be in a high temperature state, which causes great harm to the performance and safety of the electric vehicle. The application of heat pipe technology is a major development direction of battery thermal man-agement system. According to different heat pipe parameters, we use fluent software to simulate the temperature field of battery pack, and compare the influence of different heat pipes on battery pack. The results show that the heat pipe battery management system can effectively reduce the temperature of the battery and reduce the temperature difference by reasonably selecting the parameters of the heat pipe.
