According to the latest news of the official website of IEC, the latest version of IEC 62133 was released on February 7, 2017. IEC 62133 by the IEC / SC21A centralized, specifically by the WG4 responsible for the development of the first edition published in 2002, the second edition released in 2012.

 
Compared with the 2012 version, IEC 62133-3 the latest version of the following differences:
 
1. The standard is divided into two parts: nickel batteries and lithium batteries (the first part is not nickel batteries, the second part of the lithium battery);
2. Incorporating a button-type battery into this standard (the previous version does not include a button-type battery);
3. Updated 5.6 assembly of battery packs;
4. Add mechanical tests (vibration, shock);

5. Add IEC TR 62914 as a reference.

The text reads as follows:

      IEC 62133 is the world's most important international standards for lithium-ion batteries, IECEE-CB certification is also an important basis. At present, Japan, South Korea, Thailand, India and other countries have adopted IEC 62133, respectively, to develop their own national standards, these standards have become an important basis for market access in these countries
