03. Electronics Packaging and Thermal Management

The global challenge of increasing carbon emissions has led to the widespread adoption of electric vehicles as a potential solution. However, the significant heat generated by vehicle batteries presents a major challenge. To address this issue, a passive cooling thermal management system was developed. This study evaluates the effectiveness of a passive cooling system for electric vehicle batteries that integrates heat pipes, heat sink boxes, and phase change materials (PCM). The type of PCM were used: pure PCM (Rubitherm RT 22) , with the latter produced using a melt-blending method. Temperature measurements were taken using RTD PT 100 sensors connected to an Arduino for data acquisition. The research involved varying the heat generation power of a heater connected to a battery simulator, which represented operational heat losses, across three power levels and three ambient temperature variants. The results indicate that the combination of a heat sink box, NePCM, and heat pipes provides the most effective temperature reduction compared to other configurations. This integrated approach demonstrates the effectiveness of the passive cooling method for battery thermal management systems in electric vehicles, primarily due to the PCM's superior thermal conductivity and heat capacity, which help maintain the battery's recommended operating temperature range.
