The GB/T standard is the Chinese national standard for electric vehicle (EV) charging
The GB/T standard, primarily the GB/T 20234, is the Chinese national standard for electric vehicle (EV) charging. It is a set of charging station standards used in China for AC and DC fast charging of plug-in electric vehicles, known locally as "new-energy vehicles". The term "GB/T" stands for "national standard recommended" in Chinese. The GB/T standard covers a wide range of vehicles, including both electric vehicles and hybrid electric vehicles.
The standard ensures that all types of EVs can use the same charging infrastructure, simplifying the charging process for consumers and manufacturers. It specifies different charging modes and connector types, utilising a Type 2 connector designed to be compatible with all EVs. The standard also outlines security measures for DC charging, prohibiting unsafe charging modes. The GB/T standard defines specific physical requirements for connectors, ensuring compatibility with international standards such as IEC 62196 and SAE J1772.
The GB/T standard incorporates features such as electrical insulation and plug temperature monitoring to prevent overheating and ensure user and vehicle safety. It also standardises interfaces and protocols, reducing energy loss and improving overall charging speed. The Type 2 connector, commonly used in Europe, has seven conductor pins and supports both AC and DC charging. In contrast, the GB/T connector uses a flatter plug design with five conductor pins.
The GB/T standard plays a crucial role in the product design and manufacturing processes for EVs and charging infrastructure in China. Manufacturers must adhere to GB/T standards to ensure their products are compatible with the Chinese market. This includes understanding the technical specifications of the GB/T plug, such as its shape, pin configurations, and electrical requirements. The GB/T standard also includes detailed voltage and current requirements for safe and efficient charging, with the latest version supporting high-power charging up to 1.2 megawatts.
