Abstract

A charging apparatus that enables power line communication to be performed even via a charging apparatus. This charging apparatus is provided in a vehicle having an electrical storage apparatus that stores power supplied to a power supply inlet, a wheel driving section that rotates a wheel by means of power stored in the electrical storage apparatus, and an in-vehicle device that is connected to the storage apparatus via a power line; and has an AC/DC conversion section that converts power supplied from the power supply inlet from alternating-current to direct-current and outputs this to the electrical storage apparatus, and a capacitor that causes a power line communication signal input from the power supply inlet to bypass the AC/DC conversion section.

Claims

1-15. -15. (canceled)

16. A charging apparatus (12) that is provided in a vehicle having an electrical storage apparatus and an in-vehicle device, the electrical storage apparatus storing power supplied from outside, the in-vehicle device being supplied power from the electrical storage apparatus and performing power line communication for recording information from outside of the vehicle, and connects electrically an information device outside of the vehicle via a first power line, the in-vehicle device and the electrical storage apparatus via a second power line, the charging apparatus comprising:

a first power conversion section that converts first power supplied via the first power line to second power and supplies the second power to the electrical storage apparatus via the second power line; and

a first bypass section (20) that is connected to the first power conversion section in parallel, and is connected between the first power line and the second power line for bypassing a power line communication signal transmitted from the in-vehicle device or the information device.

17. The charging apparatus according to claim 16, further comprising:

a second power conversion section that converts the second power output by the electrical storage apparatus to third power and supplies the third power to another in-vehicle device; and

a second bypass section that bypasses the second power conversion section and transmits a power line communication signal transmitted from the other in-vehicle device.

18. The charging apparatus according to claim 17, further comprising

a third bypass section that is provided at least either between an input terminal of the first power conversion section and an output terminal of the second power conversion section, or between an output terminal of the first power conversion section and an input terminal of the second power conversion section, and causes the power line communication signal to bypass.

19. The charging apparatus according to claim 18,

wherein the first bypass section, the second bypass section, or the third bypass section is configured by means of a capacitor.
