Abstract: A system to provide alignment between a source resonator and a capture resonator. The source resonator is configured to emit a magnetic charging signal or a magnetic beacon signal. The source resonator is coupled to an electrical power source that provides current to the source resonator. The source resonator emits the charging signal when the current exceeds a first threshold and emits the beacon signal when the current is below a second threshold. The capture resonator is configured to receive the charging signal and provide electrical power based on the charging signal. The system also includes a magnetic sensor configured to receive the beacon signal and provide a location signal indicative of a relative location between the transmit and capture resonators to a controller that provides an alignment signal indicative of a movement required to align the source resonator and the capture resonator.

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.
