Lithium battery CQC certification GB31241 standard
About battery CQC certification
In view of the current national policies and a series of urgent requirements, whether you are a complete machine manufacturer or a large battery and mobile power manufacturer, distributor or trader, as long as the product is sold in the domestic market, you need to do CQC or GB31241, GB/T 35590 report. Batteries, mobile power supplies, etc. must be listed on Taobao Tmall Jingdong, and the commissioned inspection reports of GB31241 and GB/T 35590 are also required. Now customers have more and more stringent requirements for supplier battery products and mobile power supplies. Battery products and mobile power supplies have undergone CQC certification, which is conducive to increasing the brand awareness of certified products, enhancing product market competitiveness, and increasing market share.

CQC certification GB31241 suitable product range
International and domestic requirements have been put forward for the safety of lithium batteries. China CQC certification is a representative national certification body in China. CQC certification is also well-known internationally. “Note: CQC certification is voluntary and CCC certification is mandatory. “.
CQC mark certification is one of the voluntary product certification services carried out by the China Quality Certification Center. The application of the CQC mark indicates that the product meets the relevant quality, safety, performance, electromagnetic compatibility and other certification requirements. The certification scope involves mechanical equipment, electrical equipment , Electrical appliances, electronic products, textiles, building materials and more than 500 products. The battery GB31241 standard was enforced on August 1, 2015, replacing the previous 3306 standard. The implemented certification rules are CQC certification.
This standard applies to the following portable electronic products lithium-ion batteries and battery packs, examples are as follows:
1. Portable office products: notebook computers, PDAs, etc.;
2. Mobile communication products: mobile phones, cordless, Bluetooth headsets, walkie-talkies, etc.;
3. Portable audio and video products: portable TVs, portable DVD players, MP3/MP4 players, cameras, camcorders, voice recorders, etc.;
4. Other portable household products: electronic navigator, digital photo frame, game console, e-book, etc.
The above list is only an example, and portable electronic products include the above listed products, but are not limited to the above products.
CQC certification GB31241 does not apply to objects
For lithium-ion batteries or battery packs for portable electronic products used in special occasions such as vehicles, ships, airplanes, etc., and for special fields such as medical treatment, mining, and seabed operations, when there is no specific standard for this product, the standard can be adopted or quoted ( For reference only), but there may be additional requirements.
There are three CQC certification modes, the applicant can choose one
Certification mode 1: Type test
The basic certification process includes:
a. Application for certification
b. Product type test
c. Evaluation and approval of certification results
d. Review
Certification mode 2: Type test + initial factory inspection + supervision after certification
The basic process of certification includes:
a. Application for certification
b. Product type test
c. Initial factory inspection
d. Evaluation and approval of certification results
e. Supervision after certification
Certification mode 3: Type test + supervision after certification.
The basic process of certification includes:
a. Application for certification
b. Product type test
c. Evaluation and approval of certification results
d. Supervision after certification
From the perspective of the enterprise itself, the product has CQC certification, which means that the customer’s product has better quality and stronger competitiveness. And for the end customer products to quickly go to market to gain time and gain a competitive advantage.
