Abstract
A novel battery equalization circuit topology which has simple structure and light weight is proposed in this article. The topology is based on the "Energy Bus" which allows all the batteries connected serially can exchange their energy simultaneously. And the hardware cost of the equalization circuit board is very low. Furthermore, the capacitor is used to connect each battery to the Energy Bus, and there is on need of heavy components, such as transformer or inductor. So that the weight of the equalization circuit is very low and it is suitable for the application of aerospace. The effectiveness of this topology is verified by simulation results.
