IEC EN 61851-25 Electric Vehicle Conductive Charging System - Part 25: DC EV Supply Equipment Where Protection Is Based On Electrical Separation

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 61851-25 test. This standard provides requirements for DC EV supply equipment where the secondary circuit is protected by electrical separation from the primary circuit.

Bidirectional power flow requirements are not covered in this document. This standard also provides requirements for control and communication between DC EV supply equipment and an EV. This standard also applies to DC EV supply equipment supplied from on-site storage systems.

Matters addressed in this standard include:

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

Additional requirements may apply for equipment designed for specific environments or conditions, such as:

• DC EV supply equipment located in hazardous areas where flammable gas or vapor or flammable materials, fuels or other flammable or explosive materials are present;
• DC EV supply equipment designed to be installed at an altitude of more than 2000 m;
• DC EV supply equipment intended for use on ships.

Requirements for electrical devices and components used in DC EV supply equipment are not included in this standard and are covered by their specific product standards.

This standard specifies special requirements for DC EV supply equipment where the secondary circuit and EV are protected by electrical separation from the primary power supply circuit as defined in IEC 61140, the connection to the separated circuit is limited to a single connection.

DC EV supply equipment must limit the DC output current to the available output current parameter or cut off the power supply if the DC output current drawn by the EV exceeds the available DC output current parameter.
