Abstract: A wireless power transfer (“WPT”) pad includes a plurality of capacitors and a winding shaped for wireless power transfer. The winding is divided into a plurality of winding sections. The plurality of winding sections are connected in series with one or more capacitors of the plurality of capacitors connected in series between winding sections.

Abstract: An apparatus includes a ping detection module that detects a ping signal transmitted from a secondary pad to a primary pad. The secondary pad is located on a mobile device and the primary pad located on a stationary WPT device, where the stationary WPT device transmits power through the primary pad to the secondary pad of the mobile device during a wireless power transfer operation. The ping signal includes a mobile device ID and the mobile device ID is unique to the mobile device. The apparatus includes an ID detection module that detects the mobile device ID from the ping signal received at the primary pad and a pairing module that pairs the stationary WPT device with the mobile device in response to detecting the mobile device ID of the mobile device.

Abstract: A method for litz wire termination includes placing a ferrule over exposed conductors on an end of litz wire. The exposed conductors include a portion of the litz wire without an external insulation layer, and a portion at the end of the litz wire protrude past the ferrule. The method includes crimping the ferrule to the litz wire and placing the end of the litz wire with the ferrule in molten solder past the end of the ferrule. The method includes maintaining the litz wire in the molten solder until insulation on conductors of the litz wire is removed from the conductors in the molten solder and solder bonds to the conductors that are within in the molten solder. The method includes removing the litz wire from the molten solder and allowing the litz wire to cool until molten solder bonded to the conductors transitions to a solid state.

Abstract: An apparatus for wireless power charging includes a first charging coil with a first conductor arranged in a winding pattern with a first winding around a center point and each successive winding of the first charging coil is further away from the center point than the first winding and any previous windings. A second charging coil includes a second conductor wound with respect to the first charging coil where each coil of the second charging coil is arranged between each winding of the first charging coil. The first charging coil and second charging coil are connected in parallel. A ferrite structure is positioned adjacent to the first charging coil and the second charging coil.

Abstract: An apparatus for charge management for an electric vehicle is disclosed. A system and method also perform the functions of the apparatus. The apparatus includes a battery status module that displays a battery charge status indicator on an electronic display of an electric device. The battery charge status indicator is for a battery providing power to the electric device. The apparatus includes a charging target module that displays a charging target on the electronic display. The charging target is related to the battery charge status indicator and indicates a desired charge level for the battery. The apparatus includes a target adjustment module that adjusts the charging target based on a predicted next battery charging and battery usage, wherein the battery charging and usage are based on a schedule and/or a planned route.
