Abstract

A PLC processing device includes: a filter; a first signal firm; a second signal line; and a PLC-ECU. The filter removes noise from a signal transmitted using a power line. The filter is provided on the first signal line. In contrast, the second signal line bypasses the filter. The PLC-ECU communicates using a signal which has passed through the filter while the power storage device is being charged. The PLC-ECU communicates using a signal which has bypassed filter while the charging of the power storage device is stopped.

Claims

1. A vehicle supplied with electric power from an external power supply, comprising:

a power storage device charged with electric power supplied from said power supply; and

a communication device to communicate with a device external to said vehicle by utilizing, as a communication path, a power line to supply electric power from said power supply to said power storage device.

said communication device including;

a first signal line provided with a filter for removing noise from a signal transmitted using said power line; and

a second signal line bypassing said filter, and said communication device communicating using;

a signal having passed through said filter while said power storage device is being charged; and

a signal having bypassed said filter while the charging of said power storage device is stopped.

2. The vehicle according to claim 1, wherein

said communication device further includes a communication control unit connected to said first signal line and said second signal line,

said first signal line passes through said filter and connects said power line and said communication control unit together,

said second signal line bypasses said filter and connects said power line and said communication control unit together, and

3. A communication device for a vehicle that is configured to charge electric power supplied from an external power supply into a power storage device and to communicate with an external device by utilizing, as a communication path, a power line for supplying electric power from said power supply to said power storage device, comprising:

a first signal line provided with a filter for removing noise from a signal transmitted using said power line;

a second signal line bypassing said filter; and

a communication control unit for communicating using;

a signal having passed through said filter while said power storage device is being charged; and

a signal having bypassed said filter while the charging of said power storage device is stopped.

4. The communication device for a vehicle according to claim 3, wherein

said communication control unit is connected to said first signal line and said second signal line,

said first signal line passes through said filter and connects said power line and said communication control unit together,
