Abstract
Systems, methods and apparatus for wireless charging are disclosed. A charging device has a plurality of charging cells provided on a charging surface, a charging circuit and a controller. The controller may be configured to cause the charging circuit to send pings from a plurality of charging coils using an analog ping process to scan for one or more ping responses from a receiving device in proximity to the charging surface. A subset of charging coils of the plurality of charging coils that received ping responses from the receiving device in response to the sending of pings with the analog process may be determined. Subsequently, the controller then sends pings from the subset of charging coils using a digital ping process. A combination of one or more charging coils of the subset of charging coils may then be selected based on ping responses from the receiving device.
