    • The present invention relates to a method for excluding a cross-connected wireless power receiver in a wireless power transmitter. The method includes: determining transmission power while the wireless power transmitter is connected to the wireless power receiver; transferring the determined transmission power to the wireless power receiver; receiving a report indicating a power-receiving state from the wireless power receiver; determining whether the power-receiving state indicated by the report is within a valid range corresponding to the transmission power; and terminating the connection to the wireless power receiver if the power-receiving state is outside the valid range.
