Abstract
On the basis of the existing research results,this paper proposes a specific model to analyze the heat production of battery modules,and combines the finite element simulation calculation method to further explore the heat flux characteristics of batteries under different constant current rate conditions based on different ambient temperature conditions.The results show that the proposed improvement scheme of the battery module air duct based on the simulation analysis results can effectively reduce the maximum temperature of the battery module and solve the problem of uneven internal temperature distribution,which can provide a reference for the subsequent optimization of the battery design of commercial electric vehicles.
