Heat Dissipation Design of Power Battery Module Based on Air Cooling - Semiconductor Refrigeration

Abstract

In order to ensure that the soft package power battery can work stably for a long time under the condition of large discharge rate, the heat dissipation of the soft package power battery module is optimized based on the semiconductor thermoelectric effect. Based on the establishment of a traditional air-cooled heat dissipation model and air-cooled-thermoelectric cooler heat dissipation model and ANSYS simulation comparison, the maximum temperature difference, maximum temperature and average temperature of the battery module are analyzed. The optimized simulation results show that the temperature control of the battery module by air cooling-thermoelectric cooler can effectively reduce the temperature difference and the maximum temperature of the battery module. The method significantly improves the heat dissipation performance of the battery module.
