国家标准《电化学储能电站设计标准》时隔10年修订发布

Core Viewpoint - The article discusses the release of the revised national standard GB/T 5104 8-2025 for the design of electrochemical energy storage stations, which will be implemented on April 1, 2026. The standard updates design requirements based on ten years of operational experience with various electrochemical storage batteries, including lithium-ion and sodium-ion batteries, while removing requirements for sodium-sulfur batteries [2][4]. Summary by Sections Technical Content - The main technical revisions include the removal of sodium-sulfur battery design requirements and the addition of design requirements for sodium-ion batteries and electrolysis hydrogen/fuel cell storage stations [6][17]. - Modifications were made to battery selection and grouping requirements, including the addition of requirements for direct current side disconnection devices [6][17]. - The battery management system and energy storage inverter technical requirements have been updated [6][17]. - New layout requirements for lithium-ion and sodium-ion battery prefabricated cabins were introduced, including maximum area limits of 50 m² and 25 m² for adjacent and two-layer arrangements, respectively [3][6]. - The height requirement for indoor battery cabinets/racks was modified to 2400 mm [3][6]. - The fire hazard classification for lead-acid/lead-carbon and flow batteries was raised from Class E to Class D, and fire protection design requirements for lithium-ion batteries were revised [3][6]. - Specific fire safety design requirements for energy storage stations, including layout, evacuation, fire water supply, and automatic fire alarm systems, were updated [6][17]. - New requirements for fire protection power supply, emergency lighting, safety exit signs, and fire emergency lighting fixtures were added [6][17]. Implementation and Management - The standard is managed by the Ministry of Housing and Urban-Rural Development and was drafted by various organizations, including the Southern Power Grid and the China Electric Power Research Institute [7][8]. - The standard aims to ensure the safety, reliability, energy efficiency, and economic feasibility of electrochemical energy storage station designs [17][18]. Site Selection and Planning - Site selection for electrochemical energy storage stations should consider factors such as power system planning, load distribution, and land use, ensuring that sites are not located in hazardous areas [26][28]. - The design elevation for large energy storage stations should not be lower than the historical maximum flood level for a 1% frequency, while smaller stations should not be lower than the 2% frequency flood level [28][30]. General Requirements - The design of electrochemical energy storage stations must align with the development level of electrochemical storage technology, application scenarios, and construction conditions, ensuring safety, reliability, and environmental protection [22][23]. - The rated capacity of energy storage stations should be determined based on various application scenarios, including peak shaving and emergency power support [23][24].
