Abstract: This disclosure provides systems, methods and apparatuses for wireless power transmission and reception. A wireless power transmission apparatus may include a primary coil that transmits power to a corresponding secondary coil in a wireless power reception apparatus. The wireless power transmission apparatus may configure characteristics of the wireless power transmission based on a load setting of a wireless power reception apparatus. The wireless power transmission apparatus may take into account a coupling factor and power transfer characteristics of the wireless power reception apparatus in determining a configuration of the wireless power transmission from the wireless power transmission apparatus to the wireless power reception apparatus. In some implementations, a change in wireless power transmission may occur based on a corresponding change in the load. For example, the change in wireless power transmission and the corresponding change in the load may occur in relation to a synchronization event.

Abstract: This disclosure provides systems, methods and apparatuses for foreign object detection (FOD) in a wireless power transfer (WPT) system. Some implementations relate generally to the use of detection coils that are excited to measure and compare a differential current through a coil pair that includes at least two detection coils. A foreign object may cause a change in impedance for one or more detection coils compared to one or more other detection coils. By detecting the differential current of the coil pair, a detection apparatus may determine that a foreign object is in proximity to one of the detection coils of the coil pair. This disclosure provides several options for the design, construction, layout, and operations of detection coils to improve foreign object detection.
