摘要： A wireless power receiving appliance is configured to wirelessly receive power from a wireless power transmitter. The appliance includes: an NFC device electromagnetically coupled to another NFC device of the wireless power transmitter and a field strength indicator. The field strength indicator: receives from an NFC antenna of the NFC device a representative signal of the strength of the NFC field between the NFC device and the another NFC device, compares a value of the representative signal with at least one reference value, and emits a user signal depending on the comparison between the value of the representative signal and the at least one reference value. The user signal displays an indication of the position of the appliance with respect to the wireless power transmitter.
