Evaluation and Comparative Study of Cell Balancing Methods for Lithium-Ion Batteries Used in Electric Vehicles

Vehicle manufacturers positioned electric vehicles (EVs) and hybrid (HEVs) as reliable, safe environmental friendly alternative to traditional fuel based vehicles. Charging EVs using renewable energy resources reduce greenhouse emissions. The Lithium-ion (Li-ion) batteries used in are susceptible failure due voltage imbalance when connected form a pack. Hence, it requires proper balancing system categorised into passive active systems on the working principle. It is prerogative of battery management (BMS) designer choose an appropriate depending application. This study compares evaluates against widely inductor order select scheme addressing efficiency speed for E-vehicle segment (E-bike, E-car E-truck). implemented “top-balancing” algorithm which balance cells voltages near end charge better accuracy effective balancing. most important characteristics such degree imbalance, power loss temperature variation determined by their influence performance cost. To enhance life, Matlab-Simscape simulation-based analysis performed fine tune cell optimal usage For simulation requirements, model parameters obtained least-square fitting data through electro chemical impedance spectroscopy (EIS) test. achieved time balancer fourteen were 48 20 min deviation 30 mV. Also, recorded was 215 42 200
