METHOD FOR TRANSMITTING POWER WIRELESSLY, METHOD FOR RECEIVING POWER WIRELESSLY, WIRELESS POWER TRANSMITTING DEVICE, AND WIRELESS POWER RECEIVING DEVICE

摘要

According to the present invention, the wireless power transmitting device for transmitting power wirelessly includes: a signal processing unit for processing a communication signal to communicate with an external device; a wireless power transmitting unit for outputting a predetermined amount of wireless power to the external device and transmitting/receiving the communication signal to/from the external device; and a control unit for controlling the signal processing unit to generate a detection signal for detecting an external device in order to output the generated detection signal to the wireless power transmitting unit, to allocate an ID to an external device which outputs an authentication signal on the basis of the time at which the authentication signal is received upon receiving the authentication signal according to the detection signal, and to generate the communication signal having the ID to be outputted to the external device in order to output the generated communication signal to the wireless power transmitting unit, and controlling the signal processing unit to determine whether or not the wireless power is allocated to the external device on the basis of charge-related information when the charge-related information is received from the external device having the ID allocated, to generate wireless power allocation information on whether or not the predetermined amount of wireless power is allocated to be outputted to the external device on the basis of a determination result in order to output the generated wireless power allocation information to the wireless power transmitting unit.
