On February 7, 2024, a standard revision proposal is announced by the Standardization Administration of China (SAC) to call for public comments. The newly revised standard is currently named as Safety requirements and test specifications of electric vehicle conductive supply equipment. It will be a revision based on existing national voluntary standard GB/T 39752-2021 Safety requirements and test specifications of electric vehicle conductive supply equipment. Most importantly, the call-for-comment project proposal is planning to upgrade current voluntary standard into a mandatory one.

Based on the existing GB/T 39752-2021 (implemented on October 1, 2021), the revision proposal plans to further identify and categorize safety elements of electric vehicle (EV) conductive supply equipment, optimize the content of the standard chapters, and further supplement and clarify the necessary safety requirements and test methods.

Based on the information collected and disclosed, the scope of the revised standard will be conductive supply equipment for EV with 1000V AC or 1500V DC rated output voltage and below (that are used in China), including safety requirements for charging mode 2, charging mode 3 and charging mode 4 electric vehicle conductive supply equipment.

The main contents of the revised standard will mainly include following contents:

Stipulate safety protection requirements of EV conductive supply equipment to its user and surrounding environment against risks and dangers caused by incorrect operation. Specifically for those that may initiate serious damage to the equipment and personal harm, including but not limited in electric shock, energy danger, mechanical issue, high temperature danger, fire spreading etc.

Elaborate general requirements for equipment structure, shell material, handle and manual control, connection, and splicing, wiring and opening, electrical parts, etc.

Specify decisive voltage class limits, direct contact protection and indirect contact protection, electrical clearance and creepage distance, insulation resistance and dielectric strength requirements of such equipment.

Foreign stakeholders and MNCs should be aware that the revised standard does not address function, performance or other characteristics of conductive supply equipment that are not related to safety. It also does not involve safety requirements related to transport packaging, improper installation, and application. Requirements of EMC, information security requirements and other safety issues caused by vandalism and other purposeful acts are also not covered. The standard escalates from voluntary to mandatory also may initiate some further compliance risks that could involve product modification.
