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.

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.
