This document applies to the DC EV supply equipment for charging electric road vehicles, with a rated supply voltage up to 480V AC or up to 600 V DC withoutput voltages up to 120 V DC and output currents up to 100 A DC. This document provides the requirements for the DC EV supply equipment where the secondary circuit is protected from primary circuit by electrical separation. Requirements for bi-directional power flow are not treated in this document. This document also provides the requirements for the control communication between a DC EV supply equipment and an EV. This document also applies to DC EV supply equipment where primary power is supplied from on-site storage systems. The aspects covered in this document include: " the characteristics and operating conditions of the DC EV supply equipment; " the specification of the connection between the DC EV supply equipment and the EV; " the requirements for electrical safety for the DC EV supply equipment. Additional requirements may 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 on 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 RESS off board of the EV;
