COMMUNICATION DEVICE AND COMMUNICATION SYSTEM

摘要

When a vehicle 1 including a battery 10 is charged from a power supply device 2, communication such as power line communication is performed in which a communication signal is superposed on wires contained in a charging cable 3. A communication device 14 performs communication via a pair of communication lines 16 and 17 connected to wires such as a pair of power supply lines 31 and 32 used for power supply. A pair of induction elements 145 and 146 whose one ends are connected to the pair of communication lines 16 and 17 are provided, and the other ends of the pair of induction elements 145 and 146 are connected to a ground potential via a capacitance element 147.
