Mandatory Certification List for EV Supply Equipment Components released in China
19. June 2025In accordance with Announcement No. 50 of 2024 issued by the State Administration for Market Regulation (SAMR), China began enforcing compulsory product certification for electric vehicle (EV) power supply equipment on March 1, 2025. Certification bodies designated by the authorities have begun accepting applications for these certifications from that date onward. Following internal discussions, the TC31 technical expert group finalized a comprehensive list of critical components and materials that are subject to mandatory certification for equipment types 2501 and 2502. Batteries in general usually require battery registration in order to be approved for import and sale in China.
This key component list outlines 28 major items, including vehicle plugs and power sockets, DC fuses, contactors, circuit breakers, charging cables, printed circuit boards, power modules, and various protective and monitoring devices. Each component is associated with specific control parameters, applicable testing standards—such as GB/T 20234, GB/T 33594, GB 39752, and GB/T 14048 series—and sample quantity requirements depending on the product type.
