Electrically propelled road vehicles - Connection to an external electric power supply - Safety requirements (ISO 17409:2015)

This standard specifies electric safety requirements for conductive connection of electrically propelled road vehicles to an external electric power supply.
This standard is applicable to category L6 and L7 defined by ECE regulations as well. This standard shall not exclude technology such as class II solutions.
It does not apply to motorcycles and vehicles not primarily intended as road vehicles such as material handling trucks or fork-lifts. It applies only to on-board charging circuits with maximum working voltages according to voltage class B.
It does not provide comprehensive safety information for manufacturing, maintenance and repair personnel.
The requirements when not connected to off-board equipment of the external electric power supply are specified in ISO 6469-3.
NOTE Requirements for off-board equipment of the external electric power supply are specified in IEC 61851

Véhicules routiers à propulsion électrique - Connexion à une borne d'alimentation électrique externe - Exigences de sécurité (ISO 17409:2015)

L'ISO 17409:2015 spécifie les exigences de sécurité électrique relatives aux connexions conductives des véhicules routiers à propulsion électrique à une alimentation électrique externe au moyen d'une fiche ou d'un socle de connecteur.
Elle s'applique aux véhicules routiers à propulsion électrique ayant des circuits électriques de classe de tension B. En général, elle peut s'appliquer aux motocycles et aux cyclomoteurs s'il n'existe aucune norme dédiée à ces véhicules.
Elle s'applique uniquement aux circuits d'alimentation électrique du véhicule. Elle s'applique également aux fonctions dédiées de contrôle de l'alimentation électrique utilisées pour la connexion du véhicule à une alimentation électrique externe.
Elle ne fournit pas d'exigence concernant la connexion à une borne de charge conductive en courant continu non isolée.
Elle ne fournit pas d'informations complètes concernant la sécurité pour le personnel de fabrication, de maintenance et de réparation.
Lorsque le véhicule n'est pas connecté à la borne d'alimentation électrique externe, les exigences sont spécifiées dans l'ISO 6469‑3.
NOTE 1 L'ISO 17409:2015 ne contient pas d'exigences pour les circuits d'alimentation électrique de véhicules utilisant une isolation double ou renforcée d'un équipement de classe II, mais n'a pas pour intention d'exclure de telles applications pour véhicules.
NOTE 2 Les exigences pour les systèmes d'alimentation pour VE sont spécifiées dans l'IEC 61851.

Cestna vozila na električni pogon - Priključitev na zunanje električno napajanje - Varnostne zahteve (ISO 17409:2015)

Ta standard določa električne varnostne zahteve za prevodno povezavo električno gnanih cestnih vozil na zunanje električno napajanje. Ta standard se uporablja za kategoriji L6 in L7, ki ju opredeljujejo tudi uredbe ECE. Ta standard ne sme izključevati tehnologije, na primer rešitev razreda II. Ne uporablja se za motorna kolesa in vozila, ki primarno niso namenjena za cestna vozila, na primer vozila za premikanje materiala ali viličarje. Uporablja se le za polnilna vezja v vozilu z največjo delovno napetostjo v skladu z napetostjo razreda B. Ne zagotavlja celovitih varnostnih informacij za proizvodno, vzdrževalno in servisno osebje. Zahteve, kadar ni povezave z opremo zunanjega električnega napajanja zunaj vozila, so določene v standardu ISO 6469-3. OPOMBA: Zahteve za opremo zunanjega električnega napajanja zunaj vozila so določene v standardu 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

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

constitute an endorsement.

For an explanation on the meaning of ISO specific terms and expressions related to conformity

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical

Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information.

Electrically propelled vehicles.

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.
