POWER LINE COMMUNICATION SYSTEM, CONNECTOR DEVICE, AND POWER LINE COMMUNICATION DEVICE

摘要

Provided is a power line communication system that enables increased compactness of devices for power line communication in a vehicle that performs power line communication with a power supply device via a charging cable. Further provided are a connector device and a power line communication device. The connector device (3) is provided with a filter and an electromagnetic-induction-type signal converter necessary for power line communication, and an ECU is provided with a power line communication unit that performs power line communication via the electromagnetic-induction-type signal converter. A capacitor (16), signal wiring (17), and capacitor (16) are connected in series between AC lines (11, 12) extended from the tubular section (32) of the connector device (3). The electromagnetic-induction-type signal converter is configured from a primary coil, wherein the signal wiring (17) is wound around a toroidal core (15c) fitted in the tubular section (32), and a secondary coil, wherein signal wiring (13) connected to the power line communication unit is wound around the toroidal core (15c). Notches (32a, 32b) that accept the signal wiring (17, 13) wound around the toroidal core (15c) are formed at the tubular section (32) of the connector device (3).
