Recently, many lithium battery manufacturers have come to qinsun to inquire about CB testing and certification. If you want to know what standards are needed for lithium battery CB testing and certification and the many questions about what items are tested, today I will give you an article in this issue. To introduce, the IECEE-CB system is a system for the global mutual recognition of electrical product safety test results established by the International Electrotechnical Commission (IEC) Electrical Product Qualification Testing and Certification Organization (IECEE). The CB system is based on the IEC Safety and Electromagnetic Compatibility (EMC) standards for related electronic and electrical equipment approved by IECEE, and realizes mutual recognition of the test results of 19 categories of electrical products including batteries, household appliances, information electrical equipment, and medical electrical equipment. . And different products will have different test content, please see below for details:

Lithium battery CB testing and certification standards and items
  1. Scope of battery CB certification testing
  2. Various power secondary batteries (such as batteries for power vehicles, batteries for electric road vehicles, batteries for electric tools, batteries for hybrid vehicles, etc.);
  3. Various mobile phone batteries (such as lithium ion batteries, lithium polymer batteries, nickel hydrogen batteries, etc.);
  4. Various small secondary batteries (such as laptop batteries, digital camera batteries, camcorder batteries, various cylindrical batteries, wireless communication batteries, portable DVD batteries, CD and MP3 player batteries, etc.).
  5. Lithium battery CB test report test items
