Abstract: Methods and apparatuses are provided for controlling a wireless power transmitter. First power for charging a first wireless power receiver is transmitted. Demand power information of a second wireless power receiver is received. The demand power information includes a maximum power for the second wireless power receiver. A controller identifies whether the wireless power transmitter is capable of providing the maximum power. A power adjustment command is transmitted to the second wireless power receiver, if the wireless power transmitter is not capable of providing the maximum power. The power adjustment command requests to reduce a magnitude of power to be received by the second wireless power receiver to a level within a range that the wireless power transmitter is capable of supporting. Second power for charging the first wireless power receiver and the second wireless power receiver is transmitted based on at least the reduced magnitude of power.
