Abstract
A mobile device is configured such that it can be charged using an electric power signal S2 received from a wireless power transmitter. A wireless power receiver receives the electric power signal S2. A charger circuit charges a secondary battery using the electric power received by the wireless power receiver. A sensor detects whether or not the mobile device has been moved from a charging stand after the wireless power receiver transmits, to the wireless power transmitter, an EPT (End of Power Transfer) packet that indicates that charging of the secondary battery has been completed.
