CQC mark certification is one of the voluntary product certification businesses carried out by China Quality Certification Center. By adding CQC mark, it shows that the products meet the relevant certification requirements of quality, safety, performance and electromagnetic compatibility. It aims to safeguard the interests of consumers, promote the improvement of product quality and enhance the international competitiveness of domestic enterprises. China Quality Certification Center (CQC) carries out CQC mark certification for lithium-ion batteries and battery packs in accordance with gb31241 safety requirements for lithium-ion batteries and battery packs for portable electronic products, and CQC certification for mobile power supplies in accordance with the national standard GB / T 35590-2017 general specification for mobile power supplies for information technology portable digital devices.
In view of the current national policies and a series of urgent requirements, whether you are a complete machine manufacturer or a large number of battery and mobile power manufacturers, distributors and traders, as long as your products are sold in the domestic market, you need to make CQC or gb31241 and GB / T 35590 reports. Batteries, mobile power supplies, etc. need to go to Taobao tmall jd.com, and also need to make the entrusted inspection reports of gb31241 and GB / T 35590. Now customers have more and more strict requirements for battery products and mobile power supply. CQC certification for battery products and mobile power supply is helpful to improve the brand popularity of certified products, enhance the market competitiveness of products and improve the market share.
Examples of lithium ion batteries and battery packs for portable electronic products applicable to battery CQC certification gb31241 standard are as follows:
1. Portable office products: laptop, PDA, etc;
2. Mobile communication products: mobile phones, cordless phones, Bluetooth headsets, walkie talkies, etc;
3. Portable audio / video products: portable TV, portable DVD player, MP3 / MP4 player, camera, video camera, recording pen, etc;
4. Other portable products: electronic navigator, digital photo frame, game console, e-book, etc
The above list is only an example. Portable electronic products include but are not limited to the above products.

1. Product certification application;
2. Data review;
3. Send samples;
4. Product type test;
5. Factory quality assurance capability inspection;
6. Evaluation of certification results;
7. Certificate approval;
8. Supervision after certification.
1. Factory quality assurance capability review: according to CQC factory quality assurance capability requirements and factory inspection records
2. Product consistency inspection: check the consistency of the products applying for certification, focusing on the following contents:
(1) The identity (nameplate) of the certified product is consistent with that indicated in the type test report;
(2) The consistency between the structure of the certified product and the type test sample;
(3) One of the important parts / components of certified products and the list of important parts / components in the type test report Consistency;
(4) Conduct on-site inspection according to the table of routine inspection items and confirmed inspection items.
3. Method of initial Factory review the initial Factory review can be conducted separately or combined with the initial review or supervision review of CQC certification.
Type test and Factory review can also be carried out at the same time as required. The review time of the factory is determined according to the number of units of the products applied for certification, with due consideration to the production scale of the factory, - generally, each processing site is 1-4 person days.
The specific review time is given in the special requirements for the implementation rules of protection product certification of corresponding products. The auditor's time on the road is calculated as half a working day, which is not within the number of people / days listed above.
