Abstract:
1. A power line communication system in which a vehicle-side power line communication section mounted on a vehicle side communicates with a home-side power line communication section installed in a home via a power transmission section that transmits power to be supplied to the vehicle, wherein: the power transmission section comprises a mechanical relay comprising a plurality of fixed contacts for conducting or shutting off power to be supplied to the vehicle, the home-side power line communication section transmits a communication request signal for starting communication to the power transmission section, and the vehicle-side power line communication section energizes the mechanical relay upon receiving the communication request signal transmitted by the home-side power line communication section using propagation of electromagnetic wave between the fixed contacts of the mechanical relay as a data communication path while the fixed contacts are disconnected, and then starts communication.
