Equalization circuit topologies of lithium battery strings: a brief review

Abstract

Abstract Lithium batteries are widely applied in new energy vehicles and related energy storage industries due to their superior performance. The application of an equalization circuit can effectively reduce the inconsistency of the energy of the battery pack, thereby extending the service life of the battery pack. By reviewing the mainstream balanced circuit topology, this paper proposed the comments on the ideal balanced circuit structure in the future, which is expected to serve the construction of large-scale energy storage system in the energy Internet.
