With the development of electric vehicles, the thermal safety of lithium-ion batteries (LIBs) has received a lot of attention from scholars.The temperature of the battery is an important factor affecting the performance and safety of LIBs, so a battery thermal management (BTM) system is essential.Phase change materials (PCM) can absorb or release a large amount of heat during phase change and keep the temperature largely unchanged, which has a great prospect in battery thermal management.Therefore, in this paper, a PCM-based thermal management system is designed for a 16-cell seriesconnected Li-ion battery pack, and the effects of the thermal parameters (including thermal conductivity, latent heat of phase change and melting point) on the thermal management system are investigated by numerical simulation.The results show that the pure paraffin-based BTM can reduce the maximum battery pack temperature under 3C discharge by 30°C, and the use of composite phase change material (CPCM) can substantially improve the thermal management performance.The thermal management system designed in this paper performs best when the thermal conductivity of CPCM is 2.0 W/(m-K), the melting point is between 36°C and 38°C, and the latent heat of phase change is 210 J/g.
