Abstract
Foreign object detection and related apparatuses, methods, and systems are disclosed. An apparatus includes one or more inductive coils to wirelessly couple with another inductive coil, a series capacitor electrically connected in series with the one or more inductive coils, and a controller to determine a coil current through the one or more inductive coils responsive to a capacitor voltage potential difference across the series capacitor and determine a coil power responsive to the determined coil current and a coil voltage potential difference across the one or more inductive coils.
