Summary: In this paper, a composite PCM with form-stable property is used for passive cooling of electric car battery. The results show that integrating composite PCM with forced air convection can effectively prevent battery from heat accumulation and reduce the core temperature. The addition of 4.6 wt% graphite to the composite PCM greatly improves its heat absorption capacity, while forced air convection with 20 m³/s velocity has better cooling behavior than PCM alone.

Summary: This study explores the uncertainty in the demand and supply of solar energy due to different geographical regions and proposes the utilization of various thermal energy storage systems to overcome this issue. Phase change materials (PCMs) are preferred for their high-energy storage density, although their low thermal conductivity is a challenge. To address this, metallic foam, carbon fiber, and metallic fins are integrated into the PCM container. The inclusion of metallic foam, limited to 0.1-3% of the PCM weight, slightly impacts thermal conductivity but increases costs. Additionally, adding carbon at 0.1-9% of the PCM weight improves PCM performance. The inclusion of metallic fins enhances thermal conductivity, with different shapes and sizes. Studies indicate that metallic foam composites outperform carbon composites and metallic fins.

Summary: The phenomenon of ribbon lengthening in PV modules exposed to thermal cycling is not well explained in the literature. In this study, a three layers model is proposed to explain this effect, and the predictions of the model are validated through finite element method simulations and experiments. The results show that the model predictions are consistent with the indirect measurements, but not with the direct measurements. Additionally, it is inferred that the encapsulant plays a role after the solder failure.
