China Factory 250A GBT Connector DC EV Plug for 250kW EV Charging Station

The DC fast charging standard (GB/T 20234.3) uses a different, larger connector and allows for fast charging at up to 250 kW, with current of 80/125/200/250A, and voltage of 750-1000V.However, 50 kW or other lower rated power chargers are more commonly seen, typically retaining the minimum GB/T voltage of 750V but with different current ratings. Some chargers may also follow the physical plug specified by GB/T 20234.3 but not the GB/T standard power limits by using a lower voltage than 750V, such as 500V.
