Abstract
To extend the cycle life of power battery and enhance the safety of electric vehicle, the thermal performance of the phase change material(PCM) based LiFePO4 battery thermal management system was investigated by using experimental and numerical simulation methods. The results showed that the maximum temperature and local temperature difference of the battery module were affected significantly by the content and thermal conductivity of PCM. The local temperature difference decreased with the decrease of the temperature difference between the PCM and ambient environment while the maximum temperature is steady. The PCM can effectively block the heat into the battery if the ambient temperature is too high.
