ISO 19363-2020 pdf download.Electrically propelled road vehicles – Magnetic field wireless power transfer – Safety and interoperability requirements.
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 is intended to be used for passenger cars and light duty 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;
— 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.
NOTE 1 Charging of a vehicle in motion is not considered in this edition.
NOTE 2 Bi-directional power transfer is not considered in this edition.

3.1 alignment
relative position in x- and y-direction of the secondary device (3J5) to the primary device (39) for a
given secondary device ground clearance (11k)
Note Ito entry: The coordinate system conforms with ISO 4130.
3.2 alignment tolerance area
intended WPT (322) operating area in x- and y-direction for a given secondary device ground clearance (3j)
3.3 centre alignment point
geometrical centre of the alignment tolerance area (12)
Note ito entry: The position of the centre alignment point of an MF-WPT system (18) depends on the specific centre alignment points of the primary device (3.9) and secondary device (115).
