DESIGN AND CFD ANALYSIS ON BATTERY MANAGEMENT SYSTEM IN EV

– Battery thermal management is a critical aspect of electric vehicle (EV) performance and safety. Effective cooling systems whether air, liquid, refrigerant-based, or phase-change material (PCM) cooling is essential for maintaining optimal battery temperatures and ensuring longevity. This study employs Computational Fluid Dynamics (CFD) to analyze different cooling strategies for EV battery packs, focusing on temperature distribution, heat dissipation, liquid solidification and cooling efficiency. The research investigates various battery designs, including linear, spiral, and channel-based cooling structures, using PCM (methyl palmitate) and water-based liquid cooling. The study examines heat generation across different charge rates (1C–3C) and compares the effectiveness of air, water, and hybrid cooling methods. A meshing process with 5 – 5.5 lakh elements ensured grid independence, enabling accurate simulation results.
