On March 25, 2024, the Standardization Administration of China (SAC) approved the following two mandatory standards projects for electric vehicle charging: "Safety requirements for electric vehicle conductive charging system" and "Safety requirements and test specifications of electric vehicle conductive supply equipment."
a) “Safety requirements for electric vehicle conductive charging system”
This standard is a newly developed project aimed at ensuring that charging equipment and electric vehicles meet the highest safety standards throughout their design, manufacturing, use, testing, and operation lifecycle, thereby reducing accidents and potential hazards. The standard will also promote the uniformity of industry technology, improve the quality and reliability of related charging products, enhance user experience and convenience, and reduce problems caused by technical conflicts and mismatches.
This standard will specify the general principles of safety for electric vehicle conductive charging systems, markings and warning messages, communication protocols, charging interfaces, AC charging protection, DC charging protection, and corresponding test methods. This standard applicable to:
l Electric vehicle AC charging systems and DC charging systems defined by GB/T 18487.1, including non-vehicle-mounted conductive power supply equipment with current control and/or voltage control to achieve unidirectional/bidirectional energy flow between electric vehicle rechargeable energy storage systems and the power grid (power source), with a rated voltage on the power grid side (side A) not exceeding 1000 V AC or 1500 V DC, and a rated maximum voltage on the electric vehicle side (side B) not exceeding 1000 V AC or 1500 V DC;
l Power supply equipment obtaining energy from on-site energy storage systems (such as buffer battery packs);
l Electric vehicles capable of external charging or charging and discharging, including conductive charging or charging and discharging systems for pure electric vehicles, plug-in hybrid electric vehicles, and fuel cell hybrid electric vehicles.
b) “Safety requirements and test specifications of electric vehicle conductive supply equipment”
This standard is a revision of "GB/T 39752-2021 Safety requirements and test specifications of electric vehicle conductive supply equipment."
This standard will specify the safety requirements of electric vehicle supply equipment and the relevant test environments and test methods, applicable to electric vehicle supply equipment of various types with a rated output voltage of 1000 V AC or 1500 V DC and below, including charging modes 2, 3, and 4 electric vehicle supply equipment.
