Novel thermal management system and PCM cooling is proposed for high power fast charging pile. Transient thermal analysis model is firstly given by introducing an enthalpy method. Beneficial effect of applying the PCM for the novel thermal management performance is evaluated at different charging conditions.
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 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 ).
Simulation waveforms of a new energy electric vehicle charging pile composed of four charging units Figure 8 shows the waveforms of a DC converter composed of three interleaved circuits. The reference current of each circuit is 8.33A, and the reference current of each DC converter is 25A, so the total charging current is 100A.
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.
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.
