Parameters of GBT Inlet 80~250A
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.

Introduction of GBT DC Socket
EV Charging Socket GBT Features
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.
