본 실시예의 차량 충전 장치는, 외부의 전원 공급원으로부터 공급되는 전원을 입력받는 전원 입력부와, 상기 전원 입력부를 통해서 입력받은 전원을 차량으로 전달하는 릴레이부와, 상기 릴레이부의 동작을 제어하고, 상기 차량의 충전을 제어하기 위한 파일럿 신호를 생성하는 파일럿 회로를 포함하고, 상기 파일럿 회로는 상기 파일럿 신호에 해당하는 PWM 신호의 듀티비를 가변시킴으로써 차량 충전의 중단을 유도하는 제 1 동작과, 상기 제 1 동작에 의해서도 차량 충전의 중단이 수행되지 않는 경우에 상기 릴레이부를 오픈시킴으로써 상기 차량으로 전원이 전달되지 않도록 하는 제 2 동작을 순차적으로 수행한다.

    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.
