Balance Management of Power Battery for Electric Vehicle

Abstract

The importance of power battery balanced management was explained, and from the topological structure and function of the timing, battery equalization proposals were classified. Several existing power battery balanced management proposals were analyzed, and pointing out their deficiencies. Then combining with the existing battery balanced management strategy, an improved single-inductor balanced management proposal and improved multi-inductance balanced management proposal were brought forward. Results indicate that improved single inductor balanced management plan for the transition to the inductance energy storage element, non-dissipative power in the battery pack can be transferred between any two cells, and improved multi-inductively balanced management solutions for battery management group, the group can not only balance the battery, the battery components can also be balanced.
