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.
