Fast two-stage charge equaliser based on state-of-charge (SOC) balancing for series-connected supercapacitors

Fast two-stage charge equaliser based on state-of-charge (SOC) balancing for series-connected supercapacitors

New energy storage vehicles which use supercapacitors (SCs) as the unique source of traction power are developing rapidly recently. To satisfy the operating voltage requirement of energy storage vehicle, hundreds of SCs are needed to be connected in series. In this case, there is a voltage imbalance...
