Abstract

A wireless power transfer (WPT) system for charging an electric vehicle is disclosed. The system includes a WPT coil, a positioning system, and control circuitry. The positioning system includes a positioning coil connected to a switch, wherein in a first switch state the switch is configured to connect the positioning coil to resistor circuitry, and in a second switch state the switch is configured to disconnect the positioning coil from the resistor circuitry. The control circuitry is configured to set the switch to the first switch state to connect the positioning coil to the resistor circuitry, activate the WPT coil to induce a voltage in the positioning coil, receive a measurement from the positioning coil, and determine a relative position between a vehicle assembly and a ground assembly of the WPT system based on the received measurement from the positioning coil.
