Based on energy transferring for battery packs applied on Electric Vehicle

A new nondissipative battery balance scheme for battery pack is proposed in this paper. The proposed scheme comprise a balance modular with an energy transferring inductance, switch mosfet and transformer. Simulation and experimental results show that the proposed battery balance scheme can balance the battery cells voltage and increase the battery using efficiency. Furthmore, the balance scheme can be extend easily, this balance scheme also can easy to apply on Electric Vehicle.
