Reemplaza a: BS EN ISO 17409:2017
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.
This edition does not provide requirements for mode 1.
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
It does not provide comprehensive safety information for
manufacturing, maintenance and repair personnel.
ISO 6469-3 provides general
electrical safety requirements for electrically propelled road
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failure conditions is no longer applicable as a fault protection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.
