Abstract
The two major classifications of active cell balancing methods are charge shuttling and energy converting. In this paper, flyback transformer is used as storage element to move energy from one cell to another. A multi-output flyback transformer DC/DC converter prototype is built and tested. The test batteries used in this study were 8 Ah manganese lithium battery pack. Through experiment, the advantages and disadvantages of this method are compared and the improvement is proposed.
