▍Certification Overview
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.
▍Scope of Certification
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.

Among the proposed standards, GB 3124 is undoubtedly the focus of attention. It has entered the review stage and has been published on the TBT website, expected to be released in early 2022;
In addition to GB/T 34131 and GB 8897.4, the standards worthy of attention are GB/T 34131 and GB 8897.4. GB/T4131 is about the requirements of energy storage system BMS. The rapid expansion of the battery market has caused a rapid increase in the number of product certification test items. For manufacturers in one field, they should pay special attention to the updated status of the standard. As part of the mandatory standard, GB 8897.4 is about the safety requirements of lithium primary batteries. For lithium primary batterymanufacturers, they need to pay attention to whether the content of the mandatory part has an impact on the compliance of the product.
GB 40165-2001: Lithium ion cells and batteries used in stationary electronic equipments — Safety technical specification has been published recently. The standard follows the same pattern of GB 31241 and the two standards have covered all lithium ion cells and batteries of electronic equipment. The stationary electronic equipment applied to GB 40165 includes:
