Abstract Power storage system composed by batteries and super-capacitors is an important part of the electrical vehicle. In this paper, a novel charge and discharge circuit based on hybrid cascaded multi-level converter is proposed, where the direct-series cells are replaced by a novel bridge-arm-cascaded circuit which can realize the equalization and charge-discharge control at the same time. Since each storage cell is controlled separately, the voltage balance can be realized on-time. The utilization ratio can be improved while the over-charge and over-discharge can be avoided. The output multi-level voltage can reduce the the dv/dtand harmonic while the control performance can be improved. The control strategy of the proposed circuit is analyzed in the paper. The experiment using lead-acid batteries are implemented to verify the effects of the proposed circuit.
