The paper analyzes the development needs,standardization status and requirements of zinc-iron flow batteries,proposes the construction principles and specific contents of the standard system.The system includes four subsystems:basic universal,key components,integrated system,and grid-connected operation.It is constructed based on the whole life cycle process.At the same time,this paper also puts forward suggestions for the construction of the zinc-iron flow battery standard system,including strengthening the top-level construction,closely following the market demand,advancing step by step in a hierarchical manner,and implementing the application of standards.
