실시예에 따르면, 충전 케이블을 통하여 전달되는 CP(Control Pilot) 신호를 입력 받는 CP 회로; 전기 자동차의 인렛에 결합되어 충전 케이블 연결 신호를 생성하는 PP(Plug Present or Proximity Pilot) 회로; 상기 전기 자동차의 인렛과 상기 충전 케이블 사이에 연결되는 복수개의 풀업 저항 회로; 상기 풀업 저항 회로와 선택적으로 연결되는 스위칭부; 및 상기 충전 케이블 연결 신호의 전압값이 기 설정된 기준 전압값 미만인 경우, 상기 스위칭부를 제어하여 상기 전기 자동차의 인렛과 상기 충전 케이블 사이에서 전류 전달 경로를 형성하는 풀업 저항 회로를 변경하는 제어부를 포함하는 전기 자동차 충전 장치를 제공한다.

    According to an embodiment, an electric vehicle charging controller is provided, the controller comprising: a control pilot (CP) circuit for receiving a CP signal transmitted through a charging cable; a plug present or proximity pilot (PP) circuit coupled to an inlet of an electric vehicle so as to generate a charging cable connection signal; a plurality of pull-up resistor circuits connected between the inlet of the electric vehicle and the charging cable; a switching unit selectively connected to the pull-up resistor circuits; and a control unit, which controls the switching unit such that a pull-up resistor circuit forming a current transmission path between the inlet of the electric vehicle and the charging cable is changed if the voltage value of the charging cable connection signal is less than a preset reference voltage value.
