Information on safety certification for lithium-ion batteries and battery packs
With the consumer electronics market continues to boom, the Lithium-ion batteries market is growing rapidly, not only its application scope and the quantity expand unceasingly, but the power of a single battery is also getting higher and higher. But the lithium battery safety accidents occurred continuously, also causes the people to pay more and more attention to lithium battery security. Despite the safety of lithium batteries, many international and domestic standards have put forward requirements, such as lithium battery transportation requirements (UN38.3), mobile phone battery specifications (GB/ t18287-2013), portable sealed battery safety requirements (IEC 62133:2012 /EN 62133:2013), etc. However, none of these standards are mandatory (for example, UN38.3 only applies in the field of transportation). China has been actively formulating mandatory international standards for safety requirements of lithium batteries.
CQC released the CQC11-464114-2014 safety certification rules for lithium-ion batteries and battery packs for portable electronic products on December 19, 2014, application category: CQC mark certification 142003, the revised as follows: according to the standard changed from cqc3306-2013 to GB 31241-2014. Since the date of this notice, CQC New Energy Department has begun to accept applications for lithium-ion batteries and battery pack safety certification for portable electronic products using the new rules and certification standards, Enterprises can submit certification applications through the CQC website. SAC issued Announcement no. 27 on December 5, 2014, which contains 234 national standards including the “safety requirements for lithium-ion batteries and battery packs for portable electronic products”. As can be seen from the standard code GB, this standard is a national mandatory standard, and this standard was officially implemented on August 1, 2015
