The GB/T 27930 charging standard for cable and conductive charging developed in China is suitable for both electric vehicles (EV) and hybrid electric vehicles (HEV) alike. The GB standard (Guobiao, or “national standard” in Chinese) was published by the China Elektrolity Council (CEC).

Fast-charging connector, also known as the DC connector (GB/T 20234.3), is a nine-pin connector that can provide a maximum charging power of 237.5 kW. The charging power is limited by the vehicle’s on-board charger, which is usually significantly less than the maximum capacity of the connector. This connector is commonly used in public charging stations and can charge an electric vehicle in less than an hour. The DC connector has a higher voltage and current rating than the AC connector, which enables it to deliver faster charging speeds.

Alternating Current
The GBT Plug EV standard has two types of connectors – one for slow charging and the other for fast charging. The slow-charging connector, also known as the AC connector, is a single-phase, three-pin connector. This connector is typically used for charging at home or in commercial areas where charging time is not a constraint. The AC connector can provide a maximum charging power of 27.7 kW with three-phase current. A one-phase wire provides a maximum of 8 kW charging power.
Safe Charging
GBT EV sockets are designed with safety insulation on their pinheads to prevent accidental direct contact with human hands. This insulation is meant to ensure the highest level of safety when handling the sockets, protecting the user from potential electric shock.
Investment Value
This advanced charging system is also built to last, with a robust construction that ensures reliability and longevity. The GBT socket is designed to outlast its competitors, making it an excellent long-term investment for EV owners. Its multi-avaliable current rating and easy installation make it a great choice for both residential and commercial applications.
Market Analysis
The socket is designed to be used with GBT charging connectors, which are becoming increasingly commonplace across the world. This makes it an ideal choice for those who want to charge their electric vehicles without having to worry about compatibility issues.
