CHARGING DEVICE FOR VEHICLE AND VEHICLE
First Claim
1. A charging device for a vehicle, a charging cable includes the power line, a ground line and a signal line, power is supplied from the charging device to the vehicle through the power line, the charging device comprising:
- a device-side power line communication modem for power line communication between the vehicle and the charging device;
a device-side control pilot signal generating circuit for generating control pilot signals,a device-side control pilot signal detecting circuit for detecting the control pilot signals transmitted from the vehicle through the signal line to determine whether or not the vehicle is ready for charging and whether or not the charging is completed, anda device-side low-pass filter connected to an input of the device-side control pilot signal detecting circuit and having such a frequency characteristics that allows the control pilot signals to pass through the device-side low-pass filter but removes signals having frequencies in a frequency band used for power line communication.

Abstract
A charging device for a vehicle includes a device-side power line communication (PLC) modem, a device-side control pilot (CPLT) signal generating circuit, a device-side CPLT signal detecting circuit and a device-side low-pass filter (LPF). The device-side PLC modem is used for PLC between the vehicle and the charging device. The device-side CPLT signal generating circuit is used for generating CPLT signals. The device-side CPLT signal detecting circuit is used for detecting the CPLT signals transmitted from the vehicle through the signal line to determine whether or not the vehicle is ready for charging and whether or not the charging is completed. The device-side LPF is connected to an input of the device-side CPLT signal detecting circuit and has such a frequency characteristics that allows the CPLT signals to pass through the device-side LPF but removes signals having frequencies in a frequency band used for PLC.
