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.
The goals of the workshop were to: 1) bring together all of the key stakeholders in the energy storage community, 2) share knowledge on safety validation, commissioning, and operations, and 3) identify the current gaps in understanding, managing, standardizing and validating safety in energy storage systems.
As shown in Fig. 3, many safety C&S affect the design and installation of ESS. One of the key product standards that covers the full system is the UL9540 Standard for Safety: Energy Storage Systems and Equipment . Here, we discuss this standard in detail; some of the remaining challenges are discussed in the next section.
The protocol is serving as a resource for development of U.S. standards and has been formatted for consideration by IEC Technical Committee 120 on energy storage systems. Without this document, committees developing standards would have to start from scratch. WHAT’S NEXT FOR PERFORMANCE?
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.
The ESS was considered a black box with power exchange between the ESS and the grid being measured. From the working groups, performance metrics such as round-trip efficiency, ramp rate for real and reactive power, stored energy capacity at various percent of rated power, energy capacity stability, and standby energy loss were developed.
