Comparative Analysis and Prospect of Standard System for New Energy Storage Systems

ObjectivesIn order to provide directional reference and strategic basis for promoting the standardization and normative development of new energy storage systems in China, it is necessary to evaluate the completeness and applicability of existing energy storage system standards, identify the advantages and deficiencies within the current standard system, and clarify specific standardization requirements arising from industrial development trends and emerging technologies.MethodsFirst, a standard framework for energy storage systems is developed, encompassing five domains: fundamental and generic standards, performance requirements, communication functions, testing and experimentation, and safety requirements. Second, relevant energy storage system standards from both domestic and international sources are systematically compared. Subsequently, key technical standards issued in recent years are analyzed with a focus on discerning their similarities and differences, followed by an in-depth interpretation. Finally, based on the analysis of current status, a strategic roadmap for standard development in key industrial sectors is proposed.ConclusionsCurrently, the development of China’s energy storage standard system has preliminarily established a framework covering major technical aspects, which is relatively well-developed in areas such as fundamental and generic standards as well as performance requirements. However, deficiencies such as a lack of standards or insufficient coordination persist in areas including communication protocols and fire safety regulations. In addition, discrepancies in key technical indicators among different standards remain, constraining the standardization and interoperability of energy storage systems in large-scale applications.
