The International Electrotechnical Commission (IEC) is the world's leading organization for the preparation and publication of international standards for electrical, electronic, and related technologies. Founded in 1906, the IEC provides a global platform for companies, industries, and governments to meet, discuss, and develop the international standards they require.
A Technical Committee (TC) in IEC is a group of experts responsible for developing international standards in a specific technical area. TCs are composed of national member body delegates and work through consensus to create standards that meet global industry needs. Each TC may have subcommittees (SCs) and working groups (WGs) for specialized topics.
IEC 61851-25:2020 applies to the DC EV supply equipment for charging electric road vehicles with a rated supply voltage of up to 480 V AC or up to 600 V DC, with rated output voltage not exceeding 120 V DC and output currents not exceeding 100 A DC.
This document provides the requirements for the DC EV supply equipment where the secondary circuit is protected from the primary circuit by electrical separation.
Requirements for bi-directional power flow are not covered in this document.
This document also provides the requirements for the control and the communication between DC EV supply equipment and an EV.
This document also applies to DC EV supply equipment supplied from on-site storage systems.
The aspects covered in this document include:
• characteristics and operating conditions of the DC EV supply equipment;
• specification of the connection between the DC EV supply equipment and the EV;
• requirements for electrical safety for the DC EV supply equipment.
Additional requirements can apply to equipment designed for specific environments or conditions, for example:
• DC 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;
• DC EV supply equipment designed to be installed at an altitude of more than 2 000 m;
• DC EV supply equipment intended to be used on-board ships.
Requirements for electrical devices and components used in DC EV supply equipment are not included in this document and are covered by their specific product standards.
This document does not apply to:
• safety aspects related to maintenance;
• charging of trolley buses, rail vehicles, industrial trucks and vehicles designed primarily for use off-road;
• equipment on the EV;
• EMC requirements for equipment on the EV while connected, which are covered in IEC 61851-21-1;
• charging the RESS off-board the EV.
