This part of IEC 61851 applies to EV supply equipment for charging electric road vehicles, with a rated supply voltage up to 1 000 V AC or up to 1 500 V DC. and a rated output voltage up to 1 000 V AC. or up to 1 500 V DC. Electric road vehicles (EV) cover all road vehicles, including plug-in hybrid road vehicles (PHEV), that derive all or part of their energy from on-board rechargeable energy storage systems (RESS).
This standard also applies to EV supply equipment supplied from on-site storage systems (e.g. buffer batteries).
The aspects covered in this standard include:
• the characteristics and operating conditions of the EV supply equipment;
• the specification of the connection between the EV supply equipment and the EV;
• the requirements for electrical safety for the EV supply equipment.
Additional requirements may apply to equipment designed for specific environments or
conditions, for example:
• EV supply equipment located in hazardous areas where flammable gas or vapour and/or
combustible materials, fuels or other combustible, or explosive materials are present;
• EV supply equipment designed to be installed at an altitude of more than 2 000 m;
• EV supply equipment intended to be used on board on ships;
