System and method to align a source resonator and a capture resonator for wireless electrical power transfer
First Claim
1. A method to align a source resonator and a capture resonator, said source resonator is coupled to an electrical power source to provide an electric current to the source resonator that causes the source resonator to emit a magnetic charging signal, said capture resonator disposed on a vehicle when the vehicle is being guided to a parked position, said capture resonator is configured to wirelessly receive the magnetic charging signal and provide electrical power based on the magnetic charging signal, said method comprising the steps of:
- providing a display device;
determining a vehicle track as the capture resonator approaches the source resonator;
illustrating the vehicle track on the display device as the capture resonator approaches the source resonator via the display device; and
maintaining an indication of the vehicle track on the display device as the capture resonator approaches the source resonator via the display device.

Abstract
A system and a method to provide alignment between a source resonator and a capture resonator. The system and method may be used to align a vehicle having a capture resonator to the source resonator of a wireless inductive battery charging system for an electric vehicle. The system includes a display device, a sensor to determine a location of the source resonator relative to the capture resonator, and a controller in communication with the source resonator, the capture resonator, the sensor, and the display device. The controller is programmed to determine a relative distance and a relative direction between the source resonator and the capture resonator, determine a transfer efficiency of electrical power between the source resonator and the capture resonator. The display device is configured to indicate the relative distance and the relative direction between the source resonator and the capture resonator and indicate the transfer efficiency.
