Lithium battery safety mandatory national standards

As the consumer electronics market continues to heat,Lithium ion batteries market development rapidly, expanding its application range and quantity, not only single battery energy is becoming more and more high.While competing the lithium battery safety accident, also make people more and more attention lithium safety.

Although for the safety of lithium-ion batteries, the international and domestic several criteria are proposed, such as lithium battery transport requirement (UN38.3), mobile phone battery specification (GB/T18287-2013), a portable sealed battery safety requirements (IEC62133-2012), etc., but these standards have national mandatory (e.g., UN38.3 is only applicable to transportation).For a long time, our country are actively the mandatory international standards for lithium battery safety requirements.

In December of 2014, China national standardization management committee issued announcement, 27 international standard officially promulgated GB / 31241-2014, the portable electronic products with lithium ion batteries and battery safety requirements.As can be seen from the standard GB code, the standard for national mandatory standard, and the standards will be in August 1, 2015 formally implemented.

According to GB / 31241-2014 "portable electronic products with lithium ion batteries and battery pack and safety requirements, all conform to the" no more than 18 kg of book can be used by researchers often carry portable electronic products, "the use of lithium ion batteries and battery pack, are required to perform compulsory requirements of standards.Standard for portable electronic products including but not limited to the portable office products such as notebook computer, PDA, mobile communication products such as mobile phones, cordless phones, bluetooth headset, walkie-talkie, portable audio and video products such as portable TV, portable DVD players, MP3 players, cameras, camera recorder, etc., and other portable products such as electronic navigators, digital photo frame, games, e-books, mobile power and so on.According to the original standard, "the portable electronic products listed above does not include all of the products, so not listed products is not necessarily are beyond the scope of this standard", that is to say, the future of wearable electronic products use lithium ion batteries and battery pack may also need to meet the requirements of this standard.

New country compulsive standard, in addition to a combination of several standard battery at home and abroad, such as UL, UN, IEC, etc.) in the mature security test project, also on the thermal abuse, external short circuit, falling, charging test project for the modification, such as adding the protection circuit and identifies the durability requirements, especially for the battery protection circuit is also put forward the corresponding security requirements and the specific test method, it should be said that this is for portable lithium ion battery at home and abroad a most comprehensive safety standards.It also makes the early standards promulgated by the industry's great attention.

It is understood that the standards under centralized and first draft unit for the China electronics technology standardization institute, is the institution directly under the ministry of industry and information technology.China electronics technology standardization institute will be in late January 2015 was held in Shenzhen and Shanghai organization stable cross into the new standards and training, and conference registration by the society.There will be many lithium battery industry manufacturers, test certification body and equipment manufacturers together, mutual understanding new lithium battery industry access standards.
