Abstract  

A numerical study is performed to enhance the performance of electric vehicle batteries of different shapes using different cooling methods. Three cooling approaches were examined: no cooling, water cooling, and the incorporation of nanoparticles in the cooling plate with considering variety of batteries. There are five different setups made for analysis with and without considering flow channels for single and pack up batteries. When the battery pack operated without any cooling mechanism, the maximum temperature (T_max) reached approximately 367 K. This finding underscores the inherent thermal challenges associated with uncooled battery systems, as elevated temperatures can lead to reduced efficiency and accelerated degradation. Implementing a water-cooling system resulted in a notable improvement in thermal performance. The T_max observed with water cooling was reduced around 354 K. The circulating water effectively dissipated heat from the battery pack, mitigating temperature spikes and enhancing overall thermal stability. The introduction of copper oxide (CuO) nanoparticles into the cooling plate demonstrated the most significant impact on thermal management. The T_max recorded with CuO nanoparticles cooling was substantially lower, measuring around 337 K. The findings of this study have significant implications for the design and optimization of cooling systems for the different battery packs. Efficient thermal management, as demonstrated by water cooling and CuO nanoparticles cooling, can extend the lifespan of batteries, improve overall performance, and contribute to the safety of energy storage systems.
