Electric Vehicles (EVs) offer a promising solution to address the global energy crisis and environmental challenges associated with transportation. Currently, lithium-ion (Li-ion) batteries have gained widespread preference as the primary energy source for EVs due to their numerous advantages, including superior power density. It is imperative to acknowledge that the performance and safety of Li-ion batteries are intricately linked to their operating temperature, emphasizing the need for efficient thermal management systems. From the numerical simulation point of view, the main problem consists in conducting transient thermal analysis in a 3D Computational Fluid Dynamics (CFD) environment, since it is both time and computationally intensive.
