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 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.
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.
For the practical application of fast charging pile, a large amount of joule heat is produced in the charging elements. A healthy thermal management of the fast charging module is significant in a limited space. A novel fast charging module thermal management mode using PCM and liquid cooling is firstly proposed in our research.
The temperature rises of the charging module during higher charging rates are evaluated under the different cooling themes. Subsequently, the effects of PCMs thermo-physical parameters including thermal conductivity, latent heat, and melting point are investigated.
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 ).
