Abstract
In a two-way direct balance circuit for series cells, a control unit activates a pulse generator to transmit high frequency switch control signals, and a flyback converter is utilized to perform electromagnetic transition between the cells that rapidly conveys power from the cells with high relative state of capacity (RSOC) to the flyback converter and to the cells with low RSOC. The direct energy transfer between cells provides fast and highly efficient performance.
