To improve the consistency difference in series battery pack, a modular layered active equalization method based on inductive energy storage is proposed. First, by combining the characteristics of high equalization accuracy of inductive energy storage, a novel topology is proposed, and its parameters are designed through a detailed analysis of its working principle. Second, based on the equalization principle, an adaptive equalization control strategy is designed to match the proposed topology. Third, the analysis of its topological cost and equalization performance shows that the novel topology has advantages of a simple structure, a low cost and a fast equalization speed. Finally, a simulation model is built in MATLAB/Simulink, the effectiveness of the novel equalization method under different working conditions is verified, and it is found that this method is superior to similar equalization methods in terms of equalization speed.
