GB31241-2014, "Safety Requirements for Lithium-ion Batteries and Battery Packs for Portable Electronic Products," is a safety standard specifically formulated for portable electronic products weighing no more than 18 kg. A detailed interpretation is as follows:
I. Implementation Time of GB31241-2014 Standard
The mandatory standard GB31241 for lithium batteries officially came into effect on August 1, 2015. This standard was proposed by the Ministry of Industry and Information Technology of the People's Republic of China and is archived and managed by the China Electronics Technology Standardization Institute.
II. Scope of application of GB31241-2014 standard
The GB31241-2014 standard specifically addresses the safety of lithium-ion batteries and battery packs used in mobile electronic products that weigh no more than 18kg and are designed for everyday carrying.
III. GB31241 Lithium Battery Requirements for On-site Factory Inspections of Complete Machine Products in Categories 08, 09, and 16
Effective February 1, 2016, OEM manufacturers undergoing on-site inspections must provide valid voluntary certification certificates for lithium-ion batteries and battery packs in accordance with the GB31241 standard, or provide periodic verification inspection documents that meet the requirements of Annex 1, to ensure that the products comply with the safety requirements of the standard.
IV. Overview of Test Contents in GB31241-2014 Standard
Compared with standards such as GB/T 18287-2013, GB31241-2014 sets higher requirements for the safety of lithium-ion batteries. In addition to common test items such as external short circuit, overcharge, over-discharge, low pressure, temperature cycling, and vibration, it also draws on international standards such as IEC62133, UL1642, and UL2054, adding more stringent test items such as extrusion test, combustion jet, washing, and flame retardant test.
