The transient thermal analysis model is firstly given to evaluate the novel thermal management system for the high power fast charging pile. Results show that adding the PCM into the thermal management system limits its thermal management performance in larger air convective coefficient and higher ambient temperature.
The heat power of the fast charging piles is recognized as a key factor for the efficient design of the thermal management system. At present, the typical high-power direct current EV charging pile available in the market is about 150 kW with a heat generation power from 60 W to 120 W ( Ye et al., 2021 ).
The typical cooling system for the high-power direct current EV charging pile available in the market is implemented by utilizing air cooling and liquid cooling. The heat removal rate of the air cooling scheme depends upon the airflow, fans, and heat sinks ( Saechan and Dhuchakallaya, 2022 ).
Ming et al. (2022) illustrates the thermal management performance of the charging pile using the fin and ultra-thin heat pipes, and the hybrid heat dissipation system effectively increases the temperature uniformity of the charging module.
Effect of heat generation power on charging module temperature The heat power of the fast charging piles is recognized as a key factor for the efficient design of the thermal management system.
The PCM heat absorption is meaningful in controlling the temperature rise of the charging module. However, a faster temperature rise rate for the charging module at the completely melted of PCM limits its thermal management performance in larger air convective coefficient.
