Abstract: A battery thermal management system that effectively maintains its temperature is highly desired. However, the promising cooling method utilizing phase change materials (PCM) has challenges of low thermal conductivity and sharp temperature growth after complete melting. To address the problems, a hybrid system that couples PCM/copper foam with helical liquid channels is proposed and the effects of the influencing factors are investigated numerically. Results showed that the hybrid system achieved more than 30 K temperature drop than the natural convection case. The maximum temperatures with the helical pitch of 10 mm and 40 mm were 332.28 K and 332.88 K, respectively, compared to 334.17 K for the straight-channel system. The increments of helical diameter and tube number improved the battery temperature but raised the power consumption. The flow velocity growth could significantly reduce the battery temperature, but beyond 0.05 m/s the temperature became relatively stable. In the studied ranges, the temperature reached the optimum at the foam porosity of 0.92 and was reduced with the increasing pore density. The maximum temperature with the melting point of 28 °C was around 4 K and 8 K lower than that of PCM35HC and PCM44HC cases. The conclusions in this study could provide insights into the design of hybrid battery thermal management systems.
