China: Two new standards for electric vehicle charging

 

China has published two new standards for electric vehicle charging:

• Safety requirements for electric vehicle conductive charging system (new)
• Safety requirements of electric vehicle conductive supply equipment (replacing the voluntary standard GB/T 39752-2021 as a mandatory standard)

The first one specifies the general safety principles , the safety of charging interfaces, the safety of AC charging, the safety of DC charging and the corresponding test methods of conductive charging system of electric vehicles.This document applies to AC and DC charging systems of electric vehicle , with a rated voltage on the power grid side not exceeding 1000V AC or 1500V DC, and a rated maximum voltage on the electric vehicle side not exceeding 1000V AC or 1500V DC.  It also applies to the safety requirements for charging for electric vehicle charging and discharging systems.

The second one specifies the general safety elements and testing requirements for electric vehicle supply equipment, including the design and production requirements for protecting the safety of supply equipment, users, and the surrounding environment, as well as the instruments and equipment used for compliance testing, test conditions, test sites, test methods, and calculation methods. For independent electrical accessories and auxiliary materials (such as connecting devices, cables, insulation materials, etc.) of supply equipment, they shall be used according to specific product standards in conjunction with this document.

This document applies to various types of supply equipment with a rated output voltage of 1000V AC or 1500V DC and below as defined in GB/T 18487.1, including supply equipment in charging mode 2, charging mode 3, and charging mode 4.
