說明書
When communication is connected, the power transmission control unit 180 may receive amount-of-power information on power to be received from the receiver through communication. Then, the transmission control unit 112 may transmit power to the receiver in a wireless power based on the amount-of-power information.
In the above, a method of communicating between the wireless power transmitter and receiver has been described. Through this, the wireless power transmitter may guarantee one-to-one communication between the transmitter and receiver even when transmitting a power of several kilowatts.
Hereinafter, a method of suspending the transmission of wireless power while the wireless power transmitter transmits power to the wireless power receiver in a wireless manner will be described.
A wireless power transmitter according to an embodiment of the present disclosure may receive a request signal for suspending the supply of power from the receiver through communication while transmitting power to the receiver in a wireless manner (S410).
The communication may be carried out through a communication method described above in
The request signal may include alignment state information indicating that the alignment state of the receiver has been changed. For example, the request signal may include information indicating that the receiver is currently in a state incapable of receiving wireless power from the transmitter.
