Foreword
GB/T 18487 consists of the following parts, under the general title "Electric Vehicle
Conductive Charging System".
- Part 1. General Requirements;
- Part 2. Electric Vehicles Requirements for Conductive Connection to an A.C/DC
Supply;
- Part 3. AC/DC Electric Vehicle Charging Station.
This part is Part 1 of GB/T 18487.
This part was drafted according to the rules given in GB/T 1.1-2009.
This part replaces "Electric Vehicle Conductive Charging System – Part 1. General
Requirements" (GB/T 18487.1-2001); in addition to editorial changes, it mainly differs
from GB/T 18487.1-2001 in the following technical changes.
- "3 Terms and Definitions" was modified with terms such as "charging system"
specified;
- "4 Classification" was added with different types of supply equipment specified;
- "5 General Requirements for Charging System" was added to specify the use
condition and function of charging mode;
- "6 Communication" was added to specify the communication protocol of power
supply equipment;
- "7 Electric Shock Protection" was added to specify the direct contact protection
grade of power supply equipment;
- "8 Connection between Electric Vehicle and Power Supply Equipment" was
added to specify the functionality explanation of power coupler and vehicle
coupler;
- "9 Special Requirements for Vehicle Coupler and Plug and Socket-outlet" was
added to specify the requirements for coupler temperature monitoring and locking
device, etc.
- "10 Structure Requirements for EV Supply Equipment" was added to specify the
requirements for residual current device, etc.
- "11 Performance Requirements for EV Supply Equipment" was added to specify
the requirements for contact current, etc.
- "12 Overload Protection and Short-circuit Protection" was added to specify the
Electric Vehicle Conductive Charging System –
Part 1. General Requirements
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.
