GB/T 20234 “Connection Set of Conductive Charging for Electric Vehicles” consists of
3 parts.
- Part 1. General Requirements;
- Part 2. AC charging coupler;
- Part 3. DC charging coupler.
This Part is Part 1 of GB/T 20234.
This Part was drafted in accordance with the rules given in GB/T 1.1-2009.
This Part replaces GB/T 20234.1-2011 “Connection set of conductive charging for
electric vehicles - Part 1. General requirements”. Compared with GB/T 20234.1-2011,
the main technical changes are as follows.
- Add 1000V (DC) in rated working voltage (preferred value), 10A (AC), 80A (DC)
and 200A (DC) in rated working current (preferred value). Modify the
corresponding clauses (see Clause 5 and Clause 7);
- Delete the requirement that connection set for charging of which the rated working
current exceeds 16A (not including 16A) shall be equipped with control pilot circuit
(see 6.1.5 in Edition 2011);
- Modify the protection requirements of power interface and vehicle interface (see
6.2.1 and 6.9.1);
- Make it clear that electronic locking device shall be installed on vehicle plug of DC
charging interface (see 6.3.3);
- Delete the requirement that the terminal of which the rated current exceeds 250A
shall use non-rewirable way (see 6.7.2 of Edition 2011);
- Modify some test parameters of test methods (see Table 2, Table 3, Table 4, Table
5, Table 6 and Table 7).
This Part is formulated by reference to IEC 62196-1.2014 "Plugs, socket-outlets,
vehicle connectors and vehicle inlets - Conductive charging of electric vehicles - Part
1. General requirements”. And it is based on the domestic situations.
This Part was proposed by the Ministry of Industry and Information Technology of the
People's Republic of China.
Connection set for conductive charging of electric
vehicles - Part 1 .General requirements
1 Scope
This Part of GB/T 20234 specifies the definition, requirements, testing methods and
testing specifications for connection set of conductive charging for electric vehicles.
This Part applies to connection set of conductive charging for electric vehicles, with.
