GB/T DC Charging Connector The DC fast charging standard (GBT 20234.3) uses a different, larger connector that allows fast charging of up to 250 kW. It has a current of 80125200250A and a voltage of 750-1000V. However, chargers with 50 kW or other lower power ratings are more common. The minimum GBT voltage of 750V is usually retained, but with a different current rating. Some chargers may also follow the physical plug as specified in GBT 20234.3. However, it does not follow the GBT standard power limits and uses voltages below 750V, such as 500V. GB Standards DC Charging Connector The male vehicle connector has a flattened circular shape similar to that of the Type 2 connector used for single-phase AC charging. The DC charging connector specified in GBT 20234.3 has a nominal outer diameter of 65 mm (2.6 in); the flattened top reduces the top-to-bottom height to 60.8 mm (2.39 in). There are four pins for signaling two to provide charging confirmation (CC1 CC2) and two for communication via CAN bus (S S-). In addition, the GBT 20234.3 connector provides up to 600 W of auxiliary DC power at 30V20A (A A-). GB Standards DC Charging Connector Drawing
