Summary

In this study, a novel battery thermal management system (BTMS) coupled with phase change material (PCM) is proposed to improve its performance under fast charging conditions. A battery thermal model and two-phase PCM simulation model were developed and coupled with a liquid-cooling system. The developed model was validated using experimental data, and a parametric study was conducted by changing the parameters of the PCM and the operating conditions of the liquid-cooling system. The simulation results revealed that in the proposed system, the highest maximum temperature of the battery module was 38.4°C and the maximum temperature difference was 3.9°C during the charge–discharge cycle, and both these values were simultaneously maintained within the proper range of the battery cell. The aforementioned values were 13.2°C and 10.8°C lower compared with the corresponding values for the conventional liquid-cooling method. In addition, through the optimal operating conditions, sufficient heat dissipation was achieved while shortening the operating time of the liquid-cooling system by 12.4% of the total time. Finally, the latent heat of the PCM was recovered sufficiently during the cycle. Therefore, we claim that the proposed BTMS is not only effective in terms of its cooling performance but also sufficiently usable in the continuous cycle.
