COMMUNICATION DEVICE AND COMMUNICATION SYSTEM

摘要

Provided are a communication device and a communication system which are used for communication such as power line communication or inband communication in which a communication signal is superposed on lines contained in a charging cable, when a vehicle including a power storage device is charged from a power supply device, and which suppress a noise component such as harmonic distortion caused by occurrence of ringing without greatly affecting the communication signal, when transmitting the communication signal by switching from an idle state to an operating state. A transmission circuit included in a communication device of a vehicle includes line drivers, and the line drivers transmit a communication signal via two signal lines. In the two signal lines connected to the transmission circuit, inductance elements, resistance elements, and capacitance elements are interposed in series, respectively.

1. A communication device including a signal line connected to a power supply line used for power supply, and a transmission circuit configured to transmit a communication signal via the signal line, the transmission circuit, when transmitting the communication signal, being switched from a state where it cannot transmit the communication signal to a state where it can transmit the communication signal, and
the communication device including an inductance element interposed in the signal line.
