These include performance and durability requirements for industrial batteries, electric vehicle (EV) batteries, and light means of transport (LMT) batteries; safety standards for stationary battery energy storage systems (SBESS); and information requirements on SOH and expected lifetime.
Performance and Durability Requirements (Article 10) Article 10 of the regulation mandates that from 18 August 2024, rechargeable industrial batteries with a capacity exceeding 2 kWh, LMT batteries, and EV batteries must be accompanied by detailed technical documentation.
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.
Battery cells or battery modules made available for end use without further incorporation or assembly into larger battery packs or batteries will be regarded as batteries under the regulation, subject to the requirements for the most similar battery category.
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].
While modern battery technologies, including lithium ion (Li-ion), increase the technical and economic viability of grid energy storage, they also present new or unknown risks to managing the safety of energy storage systems (ESS). This article focuses on the particular challenges presented by newer battery technologies.
