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.

Recently, the State Administration for Market Regulation (Standardization Administration) approved the
release of 106 important national standards, involving agriculture & rural areas, green environmental protection, public safety, distance education and other fields. Among them, the standards related to batteries are as follows:
GB No. Standard Name Replaced GB No.Implementation Date GB/T 24549-2020Fuel cell electric vehicles-Safety requirementsGB/T 24549-2009 2021-04-01GB/T 39086-2020 Functional safety requirements and testing methods for battery management system of electric vehicles2021-04-01 Background of GB/T 39086-2020:With the rapid development of New Energy Automobile Industry, many accidents and hidden dangers occur from time to time such as electric cars smoke, fire, and explosion and so on.
In addition to the battery itself of the defects in design and manufacturing. A greater degree as the “brain” of electric power system and as one of the three core technology of battery management system (BMS) is closely related. In addition, the release and implementation of the new national standard for EV charging has put forward new requirements for charging data collection accuracy and communication response, which requires the battery management system on the side of the vehicle to maintain connectivity with charging infrastructure, maintain coordinated control of the charging process, and ensure charging safety. Therefore, this national standard has been formulated.
