Battery thermal management plays a critical role in ensuring the performance, safety, and lifespan of electric vehicle (EV) battery packs. Excessive temperature rise and uneven thermal distribution accelerate battery degradation, reduce range, and may lead to thermal runaway events. Conventional cooling systems struggle to achieve uniform cell temperature, particularly under high charge-discharge cycles. This research proposes a CFD-based optimization approach to evaluate and improve heat transfer characteristics in battery modules. Numerical simulations are used to analyze cooling channel geometries, flow patterns, and temperature distribution. The study aims to develop an optimized thermal management configuration that minimizes temperature gradients, enhances cooling efficiency, and contributes to safer and more reliable EV operations.
