| Abstract: | For the problems of the limited number of battery modules in series and parallel and high screening and reorganization cost of echelon battery in the medium voltage cascaded echelon energy storage system,a battery pack access method and novel equilibrium control strategy involving the equilibrium between batteries,the equilibrium within batteries and the equilibrium between cells were proposed.This approach effectively reduces the echelon energy storage application difficulty of retired power battery,extends the service life of the battery pack,and has the advantages of obvious equalization effect and wide application range.The simulation and test platform were built to test and verify the feasibility of the equilibrium control strategy and its application reliability in medium voltage cascaded energy storage system. |
