Abstract

Nowadays lithium-ion battery is one of the most dependable portable sources of energy. But, state of charge (SOC) imbalance is unavoidable problem in series-connected lithium-ion cells. Therefore, a perfect balancing mechanism is required for battery management systems (BMSs) to eliminate the problems associated with SOC imbalance. It improves life and eliminates the capacity decreasing problem of the battery packs. In this paper, a new active balancing approach based on wireless power transfer technique is proposed. The proposed method is safe, easy to implement and control, lightweight, and needs less space when compared to the multi-winding transformer. A modified Royer's oscillator is used as inverter to convert DC to high frequency AC. As per the tank circuit parameter values used in experiment the circuit is resonating at 144 KHz. Working of the wireless power transfer (WPT) circuit for cell balancing is explained clearly, and then mathematical modelling, energy flow and control of two-cell balancing topology are analysed. The proposed circuit is simulated and supported with results.
