Switched-Resistor Passive Balancing of Li-Ion Battery Pack and Estimation of Power Limits for Battery Management System

The battery pack performance and expected lifespan are crucial in electric vehicle applications. Balancing the charge on a connected series parallel is due to manufacturing discrepancies distinct of each cell standard pack. In this paper, switched-resistor passive balancing-based method proposed for balancing cells management system (BMS). value available voltage at terminals balanced using resistors an electrical circuit, excess eliminated. outcome demonstrates that circuit can maintain even across cell. procedure involves individually adjusting cell’s level charge. Passive releases energy as heat by draining from have too much A balancer cost-effective solution easy install, but thermal loss resistor, it has low efficiency necessitates lengthy process. This effective reliable low-power devices portable applications such vehicles. power limits during charging discharging estimated bisection method.
