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 ).
Electric vehicle charging piles employ several common heat dissipation methods to effectively manage the heat generated during the charging process. These methods include: 1. Air Cooling: Air cooling is one of the simplest and most commonly used methods for heat dissipation in EV charging piles.
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 ).
The heat generated during fast charge duration will affect the lifetime of fast charging pile, even a fire accident. The latest data reveals that the present fastest EV charging still performs at a lower rate than internal combustion engine vehicles refueling time ( Gnann et al., 2018 ).
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.
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.
