Here's a breakdown of key standards at each level: IEC 62619 and IEC 63056 ensure safety and performance for industrial lithium-ion cells. RoHS and REACH (NPS) ensure environmental and chemical safety. This article delves into the current state of standardization for li-ion batteries, examining key areas such as materials, transportation. Recommended practices for system design, storage, installation, ventilation, instrumentation, operation, maintenance, capacity testing, and replacement of Li-ion batteries are provided in this document. While the principles covered in this document apply to all stationary standby and cycling. CNESA plays a leading role in the formulation and revision of national, industrial, and group standards for the energy storage industry. For lithium-ion batteries, these standards provide essential guidelines to meet safety requirements, improve performance, and maintain reliability. They address critical aspects such as. UL 1973: Batteries for Use in Stationary and Motive Auxiliary Power Applications UL 1642: Lithium Batteries UL 1741: Inverters, Converters, Controllers, and Interconnection System Equipment for Use with Distributed Energy Resources UL 9540A: Test Method for Evaluating Thermal Runaway Fire. This paper collects and analyzes policy regulations and standard documents related to the energy storage battery sector, examines industry development trends and the current state of standardization efforts, and explores directions for improving testing standards based on technological advancements.
