    Abstract: Methods and apparatus are provided for detecting a non-intended object of power reception by a power transmitter. Power transmission for communication is performed, when the load change is sensed that has a value greater than or equal to a predetermined threshold. It is determined whether a subscription request, for subscribing to a network is received within a predetermined time period. The power transmission for communication is stopped when the subscription request is not received within the predetermined time period. Power is transmitted to a power receiver that has transmitted the subscription request, when the subscription request is received within the predetermined time period. It is determined whether a leakage power value exceeds an allowable range, when the power state report is received from the power receiver. The transmission of the power to the power receiver is stopped, when the leakage power value exceeds the allowable range.
