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 ).
