We conduct custom research to help identify and address the unique performance and safety issues associated with large energy storage systems. Research offerings include: UL can test your large energy storage systems (ESS) based on UL 9540 and provide ESS certification to help identify the safety and performance of your system.
The Standard covers a comprehensive review of energy storage systems, covering charging and discharging, protection, control, communication between devices, fluids movement and other aspects.
Another long-term benefit of disseminating safety test information could be baselining minimum safety metrics related to gas evolution and related risk limits for creation of a pass/fail criteria for energy storage safety testing and certification processes, including UL 9540A.
As cited in the DOE OE ES Program Plan, “Industry requires specifications of standards for characterizing the performance of energy storage under grid conditions and for modeling behavior. Discussions with industry professionals indicate a significant need for standards …” [1, p. 30].
Discussions with industry professionals indicate a significant need for standards …” [1, p. 30]. Under this strategic driver, a portion of DOE-funded energy storage research and development (R&D) is directed to actively work with industry to fill energy storage Codes & Standards (C&S) gaps.
In addition to this initial performance characterization of an ESS, battery storage systems (BESS) require the tracking of the system’s health in terms of capacity loss and resistance growth of the battery cells.
