1 SCOPE
This document specifies the interoperability requirements andtesting for the vehicle side of the electric vehicle wireless powertransfer (EV-WPT) system, including system architecture,classification, technical requirements, test preparation,interoperability testing, and on-board reference device, etc.
This document is applicable to the stationary magnetic fieldwireless power transfer (MF-WPT) systems for electric vehicles, forwhich the power supply has a maximum rated voltage of 1,000V (AC)or 1,500V (DC) and of which the maximum rated output voltage is500V (DC), while for other rated output voltages this document maybe used as a reference.
