Abstract: Starting from the hybrid energy storage characteristics of lithium batteries and fuel cells,this paper compares and selects hybrid energy storage topology models and modeling methods suitable for power distribution according to the topology structures of existing literature,and selects the most suitable hybrid energy storage topology model through analysis and selection during the combination process. A hybrid energy storage model is formed by appropriate transformation methods. Finally,it is verified by simulation that the proposed model can improve the state of charge offset of the energy storage system and prolong the life of the energy storage system under the premise of power distribution.
