Inductance based Active Balancing of Lithium ion Batteries for EV Applications

An inductance based active balancing system is studied in this paper. With a reasonable control of the switches, the system shifts energy from the cells with higher State of Charge (SOC) to those with lower SOCs. The architecture design, simulation analysis as well as the determination and optimization of the system parameters are introduced in detail. A typical power Li-ion battery module for electric vehicles is used to validate the proposed balancing system, and testing results indicate that the system works effectively and with a high balancing efficiency.
