Safety testing and certification for energy storage systems (ESS)

Large batteries present unique safety considerations because they contain high levels of energy. Additionally, they may utilize hazardous materials and moving parts.

We work hand in hand with system integrators and OEMs to better understand and address these issues.

Understanding UL 9540 and ESS certification

UL 9540, the Standard for Energy Storage Systems and Equipment, covers electrical, electrochemical, mechanical and other types of energy storage technologies for systems intended to supply electrical energy. The Standard covers a comprehensive review of ESS, including charging and discharging, protection, control, communication between devices, fluids movement and other aspects.

UL 9540 provides a basis for safety of energy storage systems that includes reference to critical technology safety standards and codes, such as:

UL 1973, the Standard for Batteries for Use in Stationary, Vehicle Auxiliary Power and Light Electric Rail (LER) Applications
UL 1741, the Standard for Inverters, Converters, Controllers and Interconnection System Equipment for Use With Distributed Energy Resources

IEEE 1547 and 1547.1
CSA FC1
NFPA 70
NFPA 2
ASME Boiler and Pressure Vessel Code
ASME B31 piping codes

The standard includes additional criteria to address materials, enclosures, including walk-in enclosures, controls, piping, utility grid interaction, and special purpose interactive systems, hazardous moving parts, signage and instructions.

If successful, ESS certification can be achieved by evaluation of off-the-shelf components that are put together by the manufacturer or integrator and submitted for certification.
