Abstract

Power battery module under high-rate discharge conditions produces thermal aggregation phenomena. Generated heat during charging and discharging that distributes in battery module inconsistently affects performance of battery and so that shortens its life. In this paper, a battery module temperature equalization method is proposed with finite element analysis. The temperature field of discharging battery module with different separators between cells is simulated. Theoretical analysis result shows that thin aluminum separators between cells inside battery module can effectively cool the battery module and improve the battery module temperature uniformity, which enhance the cycle life of power battery for electric vehicle applications.
