An efficient thermal management system(TMS) can significantly improve the battery life and ensure the safe operation of the battery. In the paper, a passive thermal management system based on phase change material(PCM) was designed to solve the battery heat dissipation. The composite PCM using paraffin and foam copper was employed to improve the thermal conductivity of the PCM and the experimental research on the conductivity of the composite PCM. The performance of the TMS with the composite PCM was invest...
