ISO 17409:2020 pdf download.Electrically propelled road vehicles Conductive power transfer – Safety requirements.
ISO 17409 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 I This edition does not provide requirements for mode I.
NOTE 2 External electric circuits are not part of the vehicle.
ISO 17409 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this document the limitation of y-capacitance for protection against electric shock under single failure conditions is no longer applicable as a fault protection provision when the vehicle has a conductive DC connection to an external electric circuit.

4 Environmental and operational conditions
The requirements given in ISO 17409 shall be met across the range of environmental conditions for which the electric vehicle is designed to operate when connected to an external electric circuit (e.g. external electric power supply), as specified by the vehicle manufacturer.
NOTE See the ISO 16750 series, ISO PAS 19295 and the ISO 19453 series for guidance.
The requirements specified in ISO 17409 shall be fulfilled under all relevant energy levels (e.g. Soc of RESS) of the electric power sources of the EV.
5 Specific requirements for the vehicle inlet, plug, and cable
5.1 Requirements for the plug and cable (case A)
The plug shall comply with:
— IEC 62 196-1 or
— 1EC62196-2.
NOTE For requirements when a vehicle is equipped with a standard plug, a function box and a cable that are permanently attached to the vehicle, see IEC 62752.
See IEC 62440 for general guidance on the safe usage of cables.
A cable that is specifically intended for charging of electric vehicles is specified in IEC 62893-3 or similar national standards.
5.2 Requirements for the vehicle inlet
6 Requirements for protection of persons against electric shock
6.1 General
The requirements given in ISO 6469-3 apply to the on-board section of the vehicle power supply circuit when not connected to an external electric circuit.
6.2 Basic protection when connected to an external electric circuit
In case A, the degree of protection against contact with voltage class B live parts shall be at least IPXXD according to ISO 20653 when the plug is mated to the corresponding socket-outlet. This requirement is deemed to be met if the vehicle is equipped with an EV plug according to the IEC 62196 series.
In cases B and C, the degree of protection against contact with voltage class B live parts shall be at least IPXXD according to ISO 20653 when the vehicle connector is mated to the vehicle inlet. This requirement is deemed to be met if the vehicle is equipped with a vehicle inlet according to the IEC 62196 series.
For case D and E the vehicle manufacturer shall perform a safety analysis under consideration of IEC 61140. Additional requirements for case D and E are under consideration.ISO-17409-2020
