VEHICLE CHARGING DEVICE AND METHOD |
| 摘要 |
A vehicle charging device is provided. The vehicle charging device includes a power input unit receiving power supplied from an external power supply source, a relay unit delivering the power received through the power input unit to a vehicle, a pilot circuit controlling an operation of the relay unit and generating a pilot signal for controlling vehicle charging, wherein the pilot circuit sequentially performs a first operation for leading a stop of the vehicle charging by changing a duty ratio of a pulse width modulation (PWM) signal corresponding to the pilot signal and a second operation for allowing the power not to be delivered to the vehicle by opening the relay unit when the stop of the vehicle charging is not performed by the first operation. |
