Summary of changes to the new IEC 62619 version,
IEC 62619 version,
Standards and Certification Document
Test standard: GB31241-2014: Lithium ion cells and batteries used in portable electronic equipment―Safety requirements
Certification document: CQC11-464112-2015: Secondary Battery and Battery Pack Safety Certification Rules for Portable Electronic Devices
Background and Date of implementation
1. GB31241-2014 was published on December 5th, 2014;
2. GB31241-2014 was mandatorily implemented on August 1st, 2015. ;
3. On October 15th, 2015, Certification and Accreditation Administration issued a technical resolution on additional testing standard GB31241 for key component “battery” of the audio and video equipment, information technology equipment and telecom terminal equipment. The resolution stipulates that the lithium batteries used in the above products need to be randomly tested as per GB31241-2014, or obtain a separate certification.
Note: GB 31241-2014 is a national compulsory standard. All the lithium battery products sold in China shall conform to GB31241 standard. This standard will be used in new sampling schemes for national, provincial and local random inspection.
GB31241-2014 Lithium ion cells and batteries used in portable electronic equipment―Safety requirements
Certification documents is mainly for mobile electronic products that are scheduled to be less than 18kg and can be often carried by users. The main examples are as follows. The portable electronic products listed below do not include all products, so products not listed are not necessarily outside the scope of this standard.
Wearable equipment: Lithium-ion batteries and battery packs used in equipment need to meet standard requirements.

IEC 62619: 2022 (the second version) released on 24 May 2022 will replace the first version published in 2017. IEC 62169 covers the safety requirements of secondary lithium ion cells and batteries for industrial use. It is generally considered to be a test standard for energy storage batteries. But in addition to energy storage batteries, IEC 62169 can also be used for lithium batteries used in uninterruptable power supplies (UPS), automatic transport vehicles (ATV), emergency power supplies and marine vehicles.
There are six major changes, but the most significant one is to add requirements for EMC.
EMC testing requirements have been added to a growing number of battery standards, especially for large power and energy storage systems, including standard UL 1973 released this year. In order to meet EMC testing requirements, manufacturers should optimize and improve circuit design and use of electronic components, and conduct preliminary verification on trial-produced products to ensure that EMC requirements are met.
