Abstract: Systems and devices for wireless power transmission is provided. A system includes a ground assembly and a vehicle assembly. The ground assembly includes a primary coil and a magnetic permeable core. The vehicle assembly includes a secondary coil capable of being inductively coupled to the primary coil and one or more magnetic permeable wings disposed on top of the secondary coil. Each of the one or more magnetic permeable wings overlap the secondary coil such that each of the one or more magnetic permeable wings extend within and beyond a periphery of the secondary coil for generating additional coupling between the primary coil and the secondary coil.

Abstract: Techniques for improving the structural integrity of wireless power base and vehicle pads are provided. An example of a wireless electric vehicle pad with a foreign object detection system according to the disclosure includes a reinforced base pad cover including an interior side with a plurality of columns, and a foreign object detection loop array comprising a plurality of loop centers, the foreign object detection loop array being disposed on the interior side of the reinforced base pad cover such that each of the plurality of loop centers is disposed around a corresponding column in the plurality of columns.
