POWER RELAY DEVICE, POWER RELAY METHOD, POWER SUPPLY CONTROL DEVICE, POWER SUPPLY CONTROL METHOD, AND POWER SUPPLY CONTROL SYSTEM

摘要

The present invention relates to a power relay apparatus, power relay method, power supply control apparatus, power supply control method, and power supply control system which can readily manage individual power consumption. Output terminals 51 and 52 relay and output the AC power supplied by input terminals 41 and 42 to connected equipment. An IC chip 325, in order to receive authentication from a power supply control apparatus and receive a supply of the AC power from the power supply control apparatus to the input terminals 41 and 42, outputs stored power information to the power supply control apparatus via the input terminals 41 and 42, by subjecting a high frequency signal that is input from the power supply control apparatus via the input terminals 41 and 42 to load modulation. The high-pass filter 323 serving as a high frequency signal filter inputs the high frequency signal input via the input terminals 41 and 42 to the IC chip 325, while inhibiting the AC power having a frequency lower than the high frequency signal, which is input via the input terminals 41 and 42, from being input in the IC chip 325.
