Cell balancing in battery management system

The common subsystems of battery management system (BMS) in Electric Vehicle are SOC estimation, cell balancing and thermal management. The subsystems of the BMS are required to operate in real time and rapidly charging and discharging conditions. Besides, the BMS should be properly designed so that...
