Which standards are commonly cited for safety of stationary battery storage systems?

• A. NEC 2040, ISO 14001
• B. IEC 62619, UL 9540, UL 1973 for cells/modules, IEC 62626 family
• C. IEC 60364, NFPA 70
• D. IEC 61850, IEEE 2030.5

Answer: (B)

Standards for the safety of stationary battery storage systems come from both cell-level safety rules and system-level safety requirements, plus how the system ties into broader installations. IEC 62619 sets the safety requirements for secondary lithium cells and batteries used in stationary applications, covering how these cells must behave under fault conditions, abuse, and aging. UL 9540 provides the overarching safety framework for energy storage systems and equipment, addressing the safety of the complete system, including thermal management, fire safety, and how the system integrates with electrical infrastructure. UL 1973 covers safety for cells and modules used within energy storage systems, clarifying safety interfaces and performance at the component level. The IEC 62626 family broadens the scope to safety of electrical energy storage equipment and related practices, encompassing system-level safety considerations and interconnections. Together, these standards offer a comprehensive safety foundation for both individual batteries and the complete stationary storage system. Other options focus on areas not specific to battery safety: general electrical installation standards, or environmental management, or communications protocols, which do not address the specialized safety concerns of stationary energy storage systems.
