The Formula SAE electric racing car, powered by lithium-ion batteries renowned for their high-performance capabilities, confronts a critical challenge: the risk of thermal runaway. This perilous condition arises from battery damage, electric short circuits, and elevated temperatures, necessitating vigilant temperature management. Moreover, the battery's optimal operational range, between 15 to 35 degrees Celsius, underscores the importance of precise thermal control.
 

This research addresses the absence of an active cooling system within the Formula SAE electric racing car's battery pack, impeding efficient heat dissipation. Compounding the issue is the battery pack's location directly behind the driver's seat, resulting in limited airflow for cooling. Of greater concern, the battery pack's casing is constructed from carbon composite material, known for its substantially lower thermal conductivity compared to metals, thus impeding the dissipation of internal heat to the external environment.

To mitigate these challenges, this study conducts thermal flow analysis (CFD) to evaluate the heat dissipation performance of the Formula SAE electric racing car's battery pack and proposes solutions to enhance cooling efficiency. Specifically, an aluminum casing is investigated for its superior thermal conductivity relative to carbon composite, facilitating the transfer of heat from the inside battery cells to the external environment. Additionally, the introduction of cooling fins is explored to expedite heat dissipation. Importantly, the research demonstrates that optimizing airflow around the battery pack significantly enhances cooling performance, highlighting the critical role of battery pack placement in maintaining temperature levels conducive to optimal battery performance.
 

This study offers valuable insights and practical solutions for improving the thermal management of lithium-ion battery packs in electric racing cars, enhancing safety and performance while advancing the sustainability of electric vehicle technology.
