ISO 5474:2025

Description

This document defines the requirements and operation of the on-board vehicle equipment that enables magnetic field wireless power transfer (MF-WPT) for traction battery charging of electric vehicles. It specifies requirements for static (vehicle not in motion) and dynamic (vehicle in motion) applications. It is intended to be used for heavy duty vehicles. This does not exclude the application of systems in passenger cars or light commercial vehicles

This document addresses the following aspects for an EV device:

–¬†¬†¬†¬† safety requirements;

–¬†¬†¬†¬† transferred power and power transfer efficiency;

–¬†¬†¬†¬† ground clearance of the EV device;

–¬†¬†¬†¬† functionality with associated off-board systems under various conditions and independent of manufacturer (interoperability);

–¬†¬†¬†¬† test procedures.

EV devices that fulfil the requirements in this document are intended to operate with supply devices that fulfil the MF-WPT related requirements in the IEC 61980 series.

In this edition, multiple secondary devices (modular approach for higher power classes) are not covered.

NOTE            The dynamic application is shown in Annex C.
