Bidirectional active charge equaliser for series-connected cells

In this study, a new bidirectional charge equaliser for series-connected cells is proposed to equalise the charge of N series-connected cells in static and dynamic states, i.e. while charging, discharging and when charger/load is disconnected. The proposed topology consists of three parts: a multiplexer, H-bridge and transformer. The multiplexer section connects the target cell to the transformer....
