A power line communication apparatus that enables communication to be performed between an authentication apparatus and a vehicle, thereby enabling authentication processing to be performed, even before power is supplied to a communication section from a charging apparatus or an electrical storage apparatus. This power line communication apparatus has a communication section that communicates with a PC serving as an authentication apparatus outside the body of the vehicle via a power line, and a battery that is connected to the communication section and supplies power to the communication section; and the communication section performs authentication communication with the PC via the power line before power is supplied from the charging apparatus or the electrical storage apparatus. |
