CB Certification is a global mutual recognition system managed by the IECEE (IEC System for Conformity Testing and Certification of Electrotechnical Equipment and Components). The CB Scheme is formally called the "IECEE Scheme for Mutual Recognition of Test Certificates for Electrical Equipment" .est Certificates for Electrical Equipment ", that is, the IECEE Mutual Recognition System for Electrical Product Testing Certificates.Lithium Battery CB Certification is tested according to IEC 62133 standard. After obtaining the CB Test Certificate (CBTC), it can be converted to local certification in more than 50 member states of the CB system, such as EU CE, Japan PSE, South Korea KC, China CCC, etc., without repeating the test. The CB system greatly reduces the multinational certification cost and time of battery companies, and is an efficient channel for Lithium Battery to enter the international market.
The IECEE-CB Scheme is a global mutual recognition system for electrical product safety test results, established by the IEC (International Electrotechnical Commission) Conformity Assessment Body for Electrotechnical Equipment (IECEE). The CB Scheme is based on IEC safety and electromagnetic compatibility (EMC) standards approved by IECEE, and achieves mutual recognition of test results for 19 major categories of electrical products, including batteries, household appliances, information technology equipment, and medical electrical equipment. Currently, 54 countries worldwide are members of the CB Scheme.
1. Continuous low-rate charging: Charge for 28 days according to the method specified by the manufacturer
Acceptance criteria: No fire, no explosion, no leakage.
2. Vibration: Simulate vibration caused during transportation
Acceptance criteria: No fire, no explosion, no leakage.
3. Moulded case stress at high ambient temperature: Internal components must not be exposed when the battery is used at high ambient temperatures
Acceptance criteria:Nophysicaldistortionofthebatterycaseresultinginexposureofinternalcomponents.
4. Temperature cycling: Batteries alternately exposed to high and low temperatures must not catch fire or explode
Acceptance criteria: No fire, no explosion, no leakage.
5. Incorrect installation of a cell (nickel systems only): Simulate incorrect installation during use
Acceptance criteria: No fire, no explosion.
6. External short circuit: Short circuit positive and negative terminals must not catch fire or explode
7. Free fall: Battery dropped from 1m height to the floor must not catch fire or explode
Acceptance criteria: No fire, no explosion.
8. Mechanical shock (crash hazard): Simulate shocks encountered during transport or handling; must not catch fire, explode, or leak
Acceptance criteria: No fire, no explosion, no leakage.
9. Thermal abuse: Battery must not catch fire or explode at extremely high temperatures (130 degrees)
Acceptance criteria: No fire, no explosion.
10. Crushing of cells: Apply a 13k N force to crush the battery; must not catch fire or explode
Acceptance criteria: No fire, no explosion.
