▍Important Certification profile

“CB Certification- -IEC 62619

CB Certification profile

CB Certified IEC(Standards.The goal of CB certification is to “use more” to promote international trade;

The CB system is an international system of the (Electrical Qualification Testing and Certification System) operating on the IECEE, called short for the IEC Electrical Qualification Testing and Certification Organization. 

“The IEC 62619 is available for:

1. Lithium batteries for mobile equipment: forklift trucks, golf carts, AGV, railway, ship.

. 2. Lithium battery used for fixed equipment: UPS, ESS equipment and emergency power supply

“Information required for the project inquiry

Specification for battery cell and battery module (shall include rated voltage capacity, discharge voltage, discharge current, discharge termination voltage, charging current, charging voltage, maximum charging current, maximum discharge current, maximum charging voltage, maximum operating temperature, product size, weight, etc.)

Inverter specification table (shall include rated input voltage current, output voltage current and duty cycle, operating temperature range, product size, weight, etc.)

ESS specification: rated input voltage current, output voltage current and power, operating temperature range, product size, weight, operating environment requirements, etc

Internal product photos or structural design drawings

Circuit diagram or system design diagram

“Samples and certification time

UL 9540 certification is usually 14-17 weeks (safety assessment for BMS features must be included)

Sample requirements (see for the information below. The project will be evaluated based on the application data)

ESS:7 or so (large ESS allows multiple tests for one sample due to sample cost, but requires a minimum of 1 battery system, 3 battery modules, a certain number of Fuse and relays)

Battery core: 6 (UL 1642 certificates) or 26

BMS management system: about 4

Relays: 2-3 (if any)
