▍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

“Test samples and certification period

▍North American ESS Certification

▍North American ESS Certified Test Standards

“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)

Jun-28-2021Electromagnetic compatibility (EMC) refers to an operating status of equipment or a system working in electromagnetic environment, in which they will not issue intolerable electromagnetic interference (EMI) to other equipment, nor they will be impacted by EMI from other equipment. EMC contains the following two aspects:
Equipment or a system will not generate EMI that exceed the limit in its working environment.
Equipment or a system has certain anti-interference in electromagnetic environment, and has certain margin.
More and more electric and electronic products are produced with technology fast development. As electromagnetic interference will interfere other equipment, and also cause damage to human body, many countries has regulated compulsory rules on equipment EMC. Below is the introduction for EMC rule in EU, USA, Japan, South Korea and China that you need to comply with:
Products should comply with CE requirement on EMC and marked with “CE” logo to indicate the product comply with On a New Approach to Technical Harmonization and Standards. The directive for EMC is 2014/30/EU. This directive covers all the electric and electronic products. The directive covers many EMC standards of EMI and EMS. Below are common used standards:
Federal Communication Commission (FCC) is the regulating department for EMC. FCC has issued over 100 standards starting from Part 0. These standards are listed in 47 CFR, which is the mandatory requirement for entering American market. FCC require different certification mode according to different kinds of products.
