Abstract
A low-pass filter (63) is disposed between a residential power line (3a) and a vehicle power line (7), and attenuates a power line communication high-frequency signal. A power line communication section (60) is connected in parallel to the low-pass filter (63), performs conversion to a signal of a frequency lower than that of a power line communication high-frequency signal superimposed on the residential power line (3a) from a charge command apparatus, and communicates with a vehicle via the vehicle power line (7) by means of the converted low-frequency signal. A control section (65) controls connection or disconnection of a connection section (64) based on a charge command apparatus command signal demodulated by the power line communication section (60).
