1 Scope
This part of GB/T 18487specifies classification, general requirements, communication, electric shock protection, connection between electric vehicle and supply equipment, special requirements of vehicle coupler, plug and socket-outlet, supply equipment structure requirement, performance requirement, overload protection and short circuit protection, emergency stop, service conditions, repair, marking and description for electric vehicle conductive charging system.
This part is also applicable to EV supply equipment which acquires energy from onsite energy storage system (such as buffer battery).
Under the following special conditions, EV supply equipment shall provide additional functions:
a) Where the EV supply equipment is located in dangerous zone where there is flammable gas or steam, fuel or other combustible or explosive substance;
b) Where the EV supply equipment is designed as to be fixed at an altitude above 2 000 m.
This part is not applicable to safety requirements on maintenance of electric vehicle conductive charging system, or to the on-board charging equipment as specified in ISO 17409, or to power supply equipment of trolleybus, railway vehicle, and industrial vehicle and mainly for non-road vehicle.
