Abstract: The key factors affecting the comprehensive energy efficiency of electrochemical energy storage were analyzed. It was
pointed out that battery consistency, estimation accuracy of battery state of charge, battery fault warning performance, the
rationality of energy storage system topology structure, and the degree of multi-objective optimization of energy management all
have a significant impact on the comprehensive energy efficiency of electrochemical energy storage. Comprehensive energy
efficiency improvement methods for power stations were proposed from four aspects: battery diagnosis and warning, battery thermal
management, high-voltage level energy reserve system, and multi-objective optimization of energy management. The technical and
economic benefits were analyzed through specific engineering cases, providing theoretical and practical basis for the construction
and operation of electrochemical energy storage power stations.
