Professional battery GB31241 certification affixed to CQC standard certification. Find Mr. Cheng from Nordic Testing

Hello! I'm glad you can see this message. My name is Mr. Cheng from Nordic Testing Technology Service Co., Ltd.
The national standard "Safety Requirements for Lithium-Ion Batteries and Battery Packs for Portable Electronic Products" will be released at the end of the year and will be be enforced. The China Quality Certification Center carries out mark certification for lithium-ion batteries and battery packs. The certification implementation rules are product category numbers, and enterprise applications are now being accepted.

Series models with the same safety performance can apply for certification as a unit to save certification testing fees. The principle of unit division is that the chemical properties, capacity and packaging method are the same, and the following five points are the same

, battery shape (cylindrical, square, other)

, battery electrolyte type ( liquids and others)

, the upper limit charging voltage of the battery

, the number of batteries included

, the type of over-protection device (for battery control) Battery equipment machine or charger control).

In an application unit, select representative models as main inspection samples, and the remaining models as supplementary inspection samples. The sample quantity requirements are as follows

) Battery main inspection samples and additional inspection samples

) Battery pack main inspection samples and additional inspection samples

) For batteries and battery packs that do not have protection circuits themselves but have protection circuits in their chargers or electronic products powered by them, several electronic products powered by the battery or balun or their control circuits should also be sent .
