Abstract
The present application relates to methods of operating a charging surface, wireless charging devices, and storage media. A charging apparatus has a plurality of charging cells disposed on a charging surface disposed at a charging surface of a wireless charging device. A controller can be configured to provide a charging current to at least one active transmitting coil in the charging surface, measure a voltage across three or more transmitting coils in the charging surface, and determine that a chargeable device is moving on the charging surface based on a change in the voltage measured across the three or more transmitting coils. The charging current can cause wireless power transfer through the at least one active transmitting coil to a chargeable device located on the charging surface.
