Electrically propelled road vehicles - Conductive power transfer - Safety requirements (ISO 17409:2020)
This document specifies electric safety requirements for conductive connection of electrically propelled
road vehicles to external electric circuits. External electric circuits include external electric power
supplies and external electric loads. This document provides requirements for the charging modes
2, 3, 4, as defined in IEC 61851-1, and reverse power transfer. For mode 4, this document provides
requirements regarding the connection to an isolated DC EV charging station according to IEC 61851-23.
NOTE 1 This edition does not provide requirements for mode 1.
NOTE 2 External electric circuits are not part of the vehicle.
This document applies to the on-board sections of vehicle power supply circuits. It applies also to
dedicated power supply control functions used for the connection of the vehicle to an external electric
circuit.
It does not provide comprehensive safety information for manufacturing, maintenance and repair
personnel.
NOTE 3 ISO 6469-3 provides general electrical safety requirements for electrically propelled road vehicles.
NOTE 4 With this edition of this document the limitation of y-capacitance for protection against electric shock
under single failure conditions is no longer applicable as a fault protection provision when the vehicle has a
conductive DC connection to an external electric circuit.

Für Ladebetriebsart 4 enthält dieses Dokument Anforderungen an den Anschluss an eine isolierte Gleichstrom-Ladestation für Elektrofahrzeuge entsprechend IEC 61851 23.
ANMERKUNG Diese Ausgabe enthält keine Anforderungen für Ladebetriebsart 1.
ANMERKUNG 2 Externe Stromkreise sind nicht Teil des Fahrzeugs.
Dieses Dokument gilt für die fahrzeugseitigen Abschnitte der Versorgungsstromkreise des Fahrzeuges. Es gilt auch für spezielle Funktionen zur Steuerung der Stromversorgung, die für den Anschluss des Fahrzeugs an einen externen Stromkreis verwendet werden.
Es enthält keine umfassenden Sicherheitsinformationen für das Herstellungs-, Wartungs- und Reparaturpersonal.
ANMERKUNG 3 ISO 6469 3 enthält allgemeine elektrische Sicherheitsanforderungen für elektrisch angetriebene Straßenfahrzeuge.
ANMERKUNG 4 Mit dieser Ausgabe dieses Dokuments ist die Begrenzung der y Kapazität zum Schutz gegen elektrischen Schlag unter Einzelfehlerzustand nicht mehr als Fehlerschutzbestimmung anwendbar, wenn das Fahrzeug über eine leitfähige Gleichstromverbindung zu einem externen Stromkreis verfügt.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).
Any trade name used in this document is information given for the convenience of users and does not

This document was prepared jointly by Technical Committee ISO/TC 22, Road vehicles, Subcommittee
SC 37, Electrically propelled road vehicles, and Technical Committee IEC/ TC 69, Electric road vehicles and
electric industrial trucks.
This second edition replaces the first edition (ISO 17409:2015), which has been technically revised. The
main changes compared to the previous edition are as follows:
— terms and definitions have been updated,
— requirements for mode 1 have been removed because it is no longer relevant for new designs,
— requirements for reverse power transfer have been added,
— requirements for a DC connection with a thermal management system have been added,
— short circuit during DC charging has been reworked, and
— requirements for charging with pantograph have been added.
