The role of medium temperature curing in energy storage charging piles

Does a PCM reduce thermal management performance in a high power fast charging pile?

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.

Does PCM heat absorption control the temperature rise of a charging module?

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.

Are phase change materials suitable for thermal energy storage?

Volume 2, Issue 8, 18 August 2021, 100540 Phase change materials (PCMs) having a large latent heat during solid-liquid phase transition are promising for thermal energy storage applications. However, the relatively low thermal conductivity of the majority of promising PCMs (<10 W/ (m ⋅ K)) limits the power density and overall storage efficiency.

Does melting point temperature affect charging module thermal management performance?

In this research, the effect of melting point temperature on the charging module thermal management performance is performed. As shown in Fig. 11, when the PCM melting point temperature increases from 32 °C to 56 °C, the extreme temperature of the charging module reduces from 88.46 °C to 86.66 °C in 15 min.

Does hybrid heat dissipation improve the thermal management performance of a charging pile?

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.

Why do we use a PCM for thermal storage?

For example, thermal storage using PCMs reduces temperature swings of electronics and improves long-term reliability. However, the added mass and volume of the PCM may reduce the specific and volumetric power density in some systems.
