China approves mandatory standards for EV charging
The Chinese authority for standardization SAC (Standardization Administration of China) agreed to two proposals for mandatory standards for the charging of electric vehicles. Requirements for the conductive charging system and conductive supply equipment were approved on 25th of March 2024.
In the electric vehicle (EV) market, China is outpacing traditional automotive giants like Germany and Japan. In 2022, China saw an 82% surge in new EV sales, making up almost 60% of global EV transactions. A report by the International Energy Agency highlights that over half of the world’s electric cars are now in China. As a result, security standards have to keep up with the rapid developments.
“Safety requirements for electric vehicle conductive charging system”
This standard aims to ensure that electric vehicle (EV) charging equipment and vehicles meet safety standards throughout their lifecycle—from design to operation. By establishing uniform industry technology, it shall enhance product quality, reliability, and user convenience while reducing issues from technical mismatches. The standard outlines safety principles for EV conductive charging systems, covering aspects like markings, warnings, communication protocols, charging interfaces, and protections for both AC and DC systems. It applies to EV charging systems, including non-vehicle-mounted equipment that controls energy flow between EV batteries and the power grid, and power supply equipment using on-site energy storage systems. Additionally, it encompasses EVs capable of external charging, including pure electric, plug-in hybrid, and fuel cell hybrid vehicles. This approach aims to minimize accidents and hazards, ensuring a safer and more efficient charging infrastructure.
“Safety requirements and test specifications of electric vehicle conductive supply equipment”
This revised standard updates “GB/T 39752-2021 Safety Requirements and Test Specifications for Electric Vehicle Conductive Supply Equipment.” It details safety requirements and testing protocols for EV supply equipment, applicable to systems with a rated output voltage up to 1000 V AC or 1500 V DC. The scope covers various types of EV charging equipment, including those used in charging modes 2, 3, and 4.
