Author: CNKI Release time: July 16, 2020 Reading: 375

With the continuous booming of consumer electronics market, the lithium-ion battery market is developing rapidly, not only its application scope and quantity are expanding, but also the energy of single battery is also increasing. And the continuous explosion of lithium battery safety accidents, also makes people pay more and more attention to the safety of lithium batteries.

Although a number of international and domestic standards have put forward requirements for the safety of lithium batteries, such as transportation requirements for lithium batteries (UN38.3), specifications for batteries for mobile phones (GB / t18287-2013), safety requirements for portable sealed batteries (IEC 62133:2012 / en 62133:2013), these standards are not mandatory (for example, UN38.3 is only applicable to the field of transportation). For a long time, China has been actively formulating mandatory international standards for lithium battery safety requirements.

On December 19, 2014, China Quality Certification Center (CQC) issued cqc11-464114-2014 Safety Certification Rules for lithium-ion batteries and battery packs for portable electronic products. The application category is CQC logo certification 142003, and the revision content is as follows: according to the standard, it is modified from cqc3306-2013 to GB 31241-2014. Since the issuance date of this notice, CQC Ministry of new energy began to use the new version of implementation rules and certification standards to accept the application for safety certification of lithium-ion batteries and battery packs for portable electronic products. Enterprises can submit certification applications through CQC website.

Sac issued No.27 announcement on December 5, 2014, which contains 234 national standards including safety requirements for lithium ion batteries and battery packs for portable electronic products. It can be seen from the standard code GB that the standard is a national compulsory standard, and the standard will be formally implemented on August 1, 2015. The national standard number of lithium-ion battery and battery pack (simplified battery) for portable electronic products is GB 31241-2014. Therefore, the reference standard of battery CQC safety certification issued by China Quality Certification Center will be changed from cqc3306 to gb31241-2014.
