The present invention relates to a power relay device, a power relay method, a power supply control device, a power supply control method and a power supply control system which are capable of facilitating individual management of power consumption. Output terminals (51, 52) relay AC power supplied by input terminals (41, 42) to a connected device to output the same. In order to receive authentication from the power supply control device and receive supply of AC power to the input terminals (41, 42) from the power supply control device, an IC chip (325) outputs stored power information to the power supply control device through the input terminals (41, 42) by performing load modulation of high-frequency signals input from the power supply control device through the input terminals (41, 42). A high pass filter (323) as a high-frequency signal filter inputs, into the IC chip (325), the high-frequency signals input through the input terminals (41, 42), and prevents AC power which is input through the input terminals (41, 42) and has low frequency than the high-frequency signals from being input into the IC chip (325). |
