This Part of GB/T 20234 specifies definitions, requirements, test methods and inspection rules of charging connection assemblies for electric vehicles.
This part is applicable to the conductive charging connection assemblies for electric vehicles with
- rated AC voltage not exceeding 250A, 50 Hz, rated current not exceeding 250A;
- rated DC voltage not exceeding 1000V and rated current not exceeding 400A.
If the standardization plugs and socket-outlets according to GB 2099.1 are applied on the power coupler of the charging connection assemblies, this Part is not applicable to these plugs and socket-outlets.
Note: The vehicles in this Part refer to the externally connected charging electric automobiles.
