Adaptive passive balancing in battery management system for e?mobility

Balancing the lithium-ion battery pack is essential to enhance energy usage and life cycle of battery. This paper analyses passive cell balancing method Li-ion for e-mobility application based on loss cost estimation through simulation hardware implementation. As a part simulation, an electrical equivalent circuit model developed parameters are obtained using electrochemical impedance spectroscopy test. The experimented topologies include switched shunting resistor with appropriate control logic. Final voltage-based algorithm implemented balance cells at high state charge. Experimental results compared against theoretical investigation. Based outcome this experiment, most significant characteristics system can be by considering impact performance, loss, cost.
