    Abstract: Methods and apparatus are provided for controlling power transmission. A minimum voltage and a maximum voltage receivable at the at least one power receiver, a reference voltage used to divide a range between the minimum voltage and the maximum voltage, and a demanded voltage required by the at least one power receiver, are received from at least one power receiver. A report about a power reception condition is received from the at least one power receiver. The report includes a measured voltage at the at least one power receiver during power transmission from the power transmitter. It is determined whether the measured voltage is between the minimum voltage and the reference voltage. Power is adjusted and supplied when the measured voltage is not between the minimum voltage and the reference voltage.

    Abstract: Methods and apparatus are provided for controlling power transmission in a power transmitter against overvoltage at a power receiver. The power transmitter receives a subscription request to subscribe to a wireless power network, from the power receiver. It is determined whether power transmission is available for the power receiver. The power receiver is informed that the power transmission is beginning, when the power transmission is available. The transmission power is increased and transmitted. It is determined whether a stop request to stop increasing voltage is received at the power transmitter from the power receiver. The increase of the transmission power is stopped when the stop request is received at the power transmitter. Charging of the power receiver is started by transmitting a start charging command from the power transmitter to the power receiver.
