IEC EN 61851-1 Electric Vehicle Conductor Charging System - Standard Test for General Requirements

IEC 61851-1 applies to EV supply equipment for charging road electric vehicles with a rated supply voltage of up to 1000 V AC or 1 500 V DC and a rated output voltage of 1000 V AC or 1.

Electric road vehicles (EVs) encompass all road vehicles, including pluggable hybrid road vehicles (PHEVs), that derive all or some of their energy from onboard rechargeable energy storage systems (RESS).

Matters covered by this standard include:

• Features and operating conditions of EV supply equipment;
• Characteristics of the connection between the EV supply equipment and the EV;
• Electrical safety requirements for EV supply equipment.

This edition includes the following important technical changes from the previous edition:

• The content of IEC 61851-1 has been revised. The numbering of sentences changed as new anecdotes were added, and some content was moved for easier reading;
• As work on IEC 61851-22 has ended, all requirements from IEC 61851-22 have been moved to this standard;
• All EMC-related requirements have been removed from the text and are expected to be part of the future release of 61851-21-2;
• The inclusion of protection devices in EV supply equipment can in some cases add to the protection against electric shock as required by the installation.
