The present invention relates to an electric vehicle charging control device, and more specifically, to an electric vehicle charging control device comprising: a connection signal input terminal into which a connection signal for whether electric vehicle supply equipment (EVSE) and an electric vehicle is connected to each other is input; a charging control signal input terminal into which a charging control signal depending on the charging method of the electric vehicle is input; a sub microcontroller for detecting the connection signal and the charging control signal in a sleep state, converting from the sleep state into a wake-up state according to the connection signal, and generating a wake-up signal for driving a main microcontroller; and the main microcontroller driven by the wake-up signal to control the charging of the electric vehicle. The charging control signal input terminal includes a first charging control signal input terminal to an n^th charging control signal input terminal, which has different electric vehicle charging methods. The sub microcontroller includes a first charging control signal detection part to an n^th charging control signal detection part corresponding to the first charging control signal input terminal to the n^th charging control signal input terminal, respectively. Therefore, provided is an electric vehicle charging control device, wherein microcontrollers are divided into a sub one and a main one, and charging can be performed using all of a plurality of electric vehicle charging methods.

    본 발명은 전기자동차 충전 제어 장치에 있어서, EVSE(Electric Vehicle Supply Equipment)와 전기자동차의 연결 여부에 대한 연결 신호가 입력되는 연결 신호 입력단, 전기자동차 충전 방식에 따른 충전 제어 신호가 입력되는 충전 제어 신호 입력단, 슬립 상태에서 연결 신호 및 충전 제어 신호를 감지하고, 연결 신호에 따라 슬립 상태에서 웨이크업(wake-up) 상태로 변환하고, 메인 마이크로컨트롤러를 구동하는 웨이크업 신호를 생성하는 서브 마이크로컨트롤러, 웨이크업 신호에 의해 구동하여, 전기자동차 충전을 제어하는 메인 마이크로컨트롤러를 포함하고, 충전 제어 신호 입력단은, 서로 다른 전기자동차 충전 방식을 가지는 제1 충전 제어 신호 입력단 내지 제n 충전 제어 신호 입력단을 포함하고, 서브 마이크로컨트롤러는, 제1 충전 제어 신호 입력단 내지 제n 충전 제어 신호 입력단과 각각 대응하는 제1 충전 제어 신호 감지부 내지 제n 충전 제어 신호 감지부를 포함하는 전기자동차 충전 제어 장치에 관한 것이다.
