Simulation Methodology for Design and Development of Li-Ion Cell and Battery Pack

The thermal management of Li-ion Cell/battery pack during charging-discharging plays a significant role in the development of Electric Vehicles (EV’s). Higher heat generation with the increase in rate of charge-discharge leads to decrease in the life of li-ion cell drastically and increases the possibility of hazard. The present paper reports the methodology for optimizing the design of li-ion cell by performing the simulation to study the variation of potential difference, heat generation and temperature distribution across the cell on different charging- discharging cycles. These simulations lead to better cell design with lesser heat generation. The Computational Fluid Dynamics Analysis (CFDA) is performed for the thermal management of the battery pack for maximum heat dissipation. It is expected that this simulation methodology will provide an edge in the design of li-ion cell and battery packs with optimized performance and will ensure the safety.
