On November 23, MIIT (Ministry of Industry and Information Technology) initiated the solicitation of opinions on the mandatory national standard " Secondary lithium cells and batteries used in electrical energy storage systems – safety requirements (draft for approval）," with a deadline set for December 23, 2023. This indicates that the standard has entered its final stage and will soon be completed and released.

The scope of application for this standard includes, but is not limited to:

a) Telecommunications;

b) Central emergency lighting and alarm systems;

c) Stationary engine starting;

d) Photovoltaic systems;

e) Residential Energy Storage Systems (HESS);

f) Grid-connected/off-grid high-capacity energy storage.

During the formulation of this standard, the environmental safety section drew inspiration from internationally standard UN 38.3, and the functional safety section referenced key international standards such as IEC 62619, IEC 63056, etc. However, the standard contains technical requirements developed based on Chinese market’s actual conditions, thus there may be differences from corresponding international standards.

This standard will complement and be interrelated with "GB 31241-2022 Lithium ion cells and batteries used in portable electronic equipment — Safety technical specification," " GB 40165-2021 Lithium ion cells and batteries used in stationary electronic equipment — Safety technical specification," and "GB 38031-2020 S Electric vehicles traction battery safety requirements." Together, they form an integral part of China's safety standards system for lithium batteries and battery packs.
