Electrically propelled road vehicles — Connection to an
external electric power supply — Safety requirements
1 Scope
This International Standard specifies electric safety requirements for conductive connections of
electrically propelled road vehicles to an external electric power supply using a plug or vehicle inlet.
It applies to electrically propelled road vehicles with voltage class B electric circuits. In general, it may
apply to motorcycles and mopeds if no dedicated standards for these vehicles exist.
It applies only to vehicle power supply circuits. It applies also to dedicated power supply control
functions used for the connection of the vehicle to an external electric power supply.
It does not provide requirements regarding the connection to a non-isolated d.c. charging station.
It does not provide comprehensive safety information for manufacturing, maintenance, and repair
personnel.
The requirements when the vehicle is not connected to the external electric power supply are specified
in ISO 6469-3.
NOTE 1 This International Standard does not contain requirements for vehicle power supply circuits
using protection by class II or double/reinforced insulation but it is not the intention to exclude such vehicle
applications.
NOTE 2 Requirements for EV supply equipment are specified in IEC 61851.

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

INTERNATIONAL STANDARD ISO 17409:2015(E)
Electrically propelled road vehicles — Connection to an
external electric power supply — Safety requirements
1 Scope
This International Standard specifies electric safety requirements for conductive connections of
electrically propelled road vehicles to an external electric power supply using a plug or vehicle inlet.
It applies to electrically propelled road vehicles with voltage class B electric circuits. In general, it may
apply to motorcycles and mopeds if no dedicated standards for these vehicles exist.
It applies only to vehicle power supply circuits. It applies also to dedicated power supply control
functions used for the connection of the vehicle to an external electric power supply.
It does not provide requirements regarding the connection to a non-isolated d.c. charging station.
It does not provide comprehensive safety information for manufacturing, maintenance, and repair
personnel.
The requirements when the vehicle is not connected to the external electric power supply are specified
in ISO 6469-3.
NOTE 1 This International Standard does not contain requirements for vehicle power supply circuits
using protection by class II or double/reinforced insulation but it is not the intention to exclude such vehicle
applications.
NOTE 2 Requirements for EV supply equipment are specified in IEC 61851.
