Portable lithium battery strength standard GB 31241 -2022 interpretation

CCC certification of portable electronic lithium-ion batteries will be implemented soon. Battery recycling line GB31241-2022 "Technical Specification for Safety of Portable Electronic Lithium-ion Batteries and Batteries" (hereinafter referred to as "the new standard") was issued on December 29th, 2022, and took effect on January 1st, 2024, replacing GB31241-2014.

Lithium Battery CCC policy adjustment;

Lithium-ion batteries, lithium battery welding machine battery packs and mobile power supplies used in electronic and electrical products are subject to compulsory certification.

CCC certification rules for lithium-ion battery and battery packs for portable electronic equipment: after the publication of the new CNCA CCC catalogue, CQC will no longer issue the corresponding voluntary CQC certification, cQC will no longer issue the corresponding voluntary CQC certification.

Design requirements of new GB 31241 standard;

From March 1, 2023 to December 31, 2023, enterprises can voluntarily choose to implement certification according to the new version or the old version. mounting machine From January 1, 2024, CQC will adopt the new standard to implement the certification and issue the new standard certification certificate, and will no longer issue the old standard certification certificate.

Relevant laboratories can report the testing ability of the new standard to CQC, and record the qualification accreditation and accreditation of the new standard laboratory in time.

Data show that the economy of the portable energy storage market has grown 23-fold in size over the past four years, with the United States and Japan accounting for more than 75 per cent of the market, based on a basic analysis of the distribution of sales. Chinese developers could be the biggest beneficiaries of this wave of market research, with China accounting for 91.9 per cent of the world's portable energy storage output in 2020.

Portable energy storage capacity is generally between 100-3000 watt-hours, also known as "big charging treasure" and "outdoor power supply", which is mainly used for outdoor travel, emergency preparedness and other occasions. The utility model fills the gap between the charging pile and the fuel generator, can support short-time power consumption and is convenient to carry.
