Abstract
In some examples, a wireless charging system includes a pressure sensitive plate, a plurality of charging coils, and a base that includes one or more processors and logic instructions. The logic instructions are executable by the one or more processors to detect a device placed on the pressure sensitive plate, determine a location of the device on the pressure sensitive plate, identify one or more charging coils of the plurality of charging coils that are within a predetermined distance from the device, and activate the one or more charging coils without activating remaining charging coils of the plurality of charging coils. The one or more charging coils are sufficiently near a receiver located in the device to create inductive coupling with the receiver to charge a battery of the device.
