1 SCOPE
This document specifies the interoperability re and testing for the vehicle side of the electric vehicle wireless power transfer (EV-WPT) system, including system architecture, classification, technical re, test preparation, interoperability testing, and on-board reference device, etc.
This document is applicable to the stationary magnetic field wireless power transfer (MF-WPT) systems for electric vehicles, for which the power supply has a maximum rated voltage of 1,000V (AC) or 1,500V (DC) and of which the maximum rated output voltage is 500V (DC), while for other rated output voltages this document may be used as a reference.
