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

Recently, in related news, NTCAS Shenzhen branch organized and held the 2020 standard examination for
approval. Among various standard, voluntary national standards GB/T Security Requirements for replacing
battery of EV drafted by BAIC BJEV and NIO got approved, which will guide EV industry to a safer and healthierdevelopment. Through analyzing the difference of various technical plans, real scenario status and data of cars,new standard stipulate minimum requirements of replacing battery, 5000 times for clip-on mode and 1500 times for Screw Type, ensuring safety in design working life
The standard considers vehicles, system of battery replacing, battery pack, structure of battery replacing,
connector and other critical items as study and test objects, simulating the potential failure mode when
replacing battery. Tests referring to the standard include vibration and shock according to GB38031.
