CE certification for battery cells refers to the fact that battery cell products comply with the requirements of relevant EU directives and harmonized standards. After passing the certification, they can be affixed with the CE mark and freely circulate in the EU market. The following is a brief introduction about it:

Certification standard

The main standards for CE certification of battery cells include EN 62133, etc. EN 62133 stipulates the safety requirements for portable sealed secondary batteries and battery packs containing alkaline or non-acidic electrolytes, covering multiple aspects such as the design, manufacture and testing of batteries, aiming to ensure the safety of cells under normal use and foreseeable misuse.

Certification process

1. Submit an application: The applicant submits a formal certification application to the certification body and provides relevant product materials, such as product manuals, circuit diagrams, and material lists.

2. Product Testing: Certification bodies conduct various tests on battery cell products, including electrical safety tests, mechanical safety tests, environmental adaptability tests, etc. For instance, it will test the overcharge, overdischarge and short-circuit protection performance of the battery cells, as well as their performance stability under different temperature and humidity conditions.

3. Audit and Evaluation: The certification body audits and evaluates the product based on the test results to determine whether the product meets the requirements of CE certification.

4. Obtaining Certification: If the product passes the test and the audit assessment is qualified, the applicant will obtain the CE certification certificate, allowing the CE mark to be affixed to the product.

Certification significance

For enterprises, obtaining CE certification for battery cells can enhance the market competitiveness of their products, indicating that the products comply with the safety, health and environmental protection standards of the European Union. This helps to open up the EU market and increase consumers' trust in the products. For consumers, the CE certification mark is a guarantee of product safety and reliability, giving them more confidence when purchasing battery cell products.
