Abstract:

Amid the multiple challenges posed by high proportions of renewable energy and power electronic equipment in new power systems under "two high" background, electrochemical energy storage—characterized by high efficiency, flexibility, and technological diversity—is emerging as a core supporting technology for building new power systems and achieving dual carbon goals. Standardization in the energy storage industry is crucial for guiding technological upgrades in energy storage stations, advancing high-quality development, and fostering market-oriented growth. Currently, the electrochemical energy storage industry remains in a phase of rapid development, with existing standards insufficient to comprehensively address the industry's multifaceted needs across its entire life cycle, diverse real-world application scenarios, and multiple technology types. This study comprehensively reviews the electrochemical energy storage standards established by international standardization organizations and analyzes China's existing standard system in depth based on the 2023 Guidelines for the Construction of New Energy Storage Standard Systems. Focusing on eight key areas, ncluding basic and general standards, planning and design, equipment testing, and safety and emergency response, the study identifies major gaps, existing frameworks, and emerging standardization needs. Integrating the current technological development status of China's energy storage industry, the study proposes targeted recommendations and forward-looking insights for different stages of standard formulation. This study provides valuable references for future standard development and the healthy, orderly growth of the electrochemical energy storage sector.
