Simulation Methodology for design and development of Li-ion Cell and Battery Pack

The thermal management of Li-ion Cell/ battery pack while charging-discharging plays a significant role in the development of Electric Vehicles, as increase in rate of charge-discharge leads to higher heat generation which decrease the life of li-ion cell drastically, it also increases the possibility of hazard. The present paper reports the simulation 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 for better cell design with lesser heat generation. The Computational Fluid Dynamics Analysis is performed for the better thermal management of the battery pack so that maximum heat dissipation could take place. It is expected that this simulation methodology gives an edge in the designing of li-ion cell and battery packs and optimising the performance of cell/ battery pack and ensure the safety.
