Abstract A battery module based on harmonica tube cold plate was designed for the lithiumion battery thermal management system with electric vehicle air conditioning refrigerant to directly cool the battery pack. The comparison between direct cooling and liquid cooling was carried out, and the effects of ambient temperature, compressor speed, valve opening and discharge rate on refrigerant flow, evaporation temperature and heat dissipation characteristics of the battery pack were investigated. The results show that direct cooling has better cooling effect than liquid cooling in controlling the average temperature of the battery pack. Increasing the compressor speed has significant temperature control effect on the battery pack. Even for highrate discharge of 2.0 C, the temperature can be controlled below 40.00 ℃ at speed of 3 500 r/min. Increasing the valve opening is beneficial to reducing the average temperature of the battery pack, but it is not conducive to reducing the temperature difference of the battery pack. When the battery pack temperature difference is large, the temperature difference of single battery can account for 88% of the battery pack temperature difference.
