Abstract
A communication system comprising: a control line transmitting a control signal for controlling charging of a battery mounted on a vehicle; a reference potential line connected to a reference potential of the vehicle serving as a reference for the control signal; a first PLC communication device connected to the control line and the reference potential line and superposing onto the control signal a differential signal having a higher frequency than the control signal so as to perform communication with an external power supply apparatus; and an inductive element which is provided at a point of connection between the reference potential lineand the reference potential or provided in the reference potential line and the inductive element having impedance for a noise having a higher frequency than the control signal is higher than the impedance for the control signal.
