A wireless charging device has a plurality of charging cells provided on a first surface and a processor configured to provide a charging current to a first charging coil in a surface of the wireless charging device, determine that an impedance of a resonant circuit has varied from a threshold or setpoint impedance, and restore the threshold or setpoint impedance by modifying frequency of the charging current. The resonant circuit may include the first charging coil. A method for operating the wireless charging device includes providing a charging current to a first charging coil in a surface of the wireless charging device, determining that an impedance of a resonant circuit has varied from a threshold or setpoint impedance, and restoring the threshold or setpoint impedance by modifying frequency of the charging current.
