Summary: This paper investigates the thermal performance of refrigerant-based battery thermal management system (BTMS) for a real HEV battery pack in both cooling and heating conditions. The heat generation model of battery cells and the numerical methodology for predicting the cooling performance are validated by experiments. The effects of discharging C-rate, mass flow rate, initial temperature, and vapor quality of refrigerant on the battery pack's thermal performance are analyzed in detail. The results show that the discharging C-rate, mass flow rate, and initial temperature have significant impacts on the battery pack's thermal performance, while the effect of vapor quality is limited. The cooling performance of the refrigerant satisfies the requirement of BTMS at the real driving cycle, and the optimum heating power for the battery pack ranges from 400 W to 460 W.
