Direct active cell balancing with integrated cell monitoring [PDF]

IET Electrical Systems in Transportation, 2019
In this study, an active battery balancing system is proposed, which allows direct energy transfer between arbitrary cells within a cell stack with simultaneous cell monitoring. The energy transfer utilises only one energy storage for the balancing process of the whole stack. Furthermore, the design enables the reduction of required sensors to only one
