The present invention relates to a method for controlling a charging current to reduce charging time of an electric vehicle. According to the present invention, the method for controlling a charging current to reduce charging time of an electric vehicle includes: a step of monitoring a charging voltage and a first actual charging current of an electric vehicle; a step of comparing the first actual charging current of the electric vehicle with a reference current which can be supplied in an electric vehicle charger; a step of changing a first charging-allowable current of the electric vehicle charger supplying the charging current to the electric vehicle when the reference current of the electric vehicle charger and the first actual charging current of the electric vehicle are difference; and a step of transmitting a second charging-allowable current changed as much as a predetermined value to the electric vehicle and comparing the reference current and a second actual charging current by measuring the second actual charging current of the electric vehicle according to the second charging-allowable current. Accordingly, the method for controlling a charging current to reduce charging time of an electric vehicle can reduce charging time of the electric vehicle and solve a problem caused by leakage of charging facilities by improving charging efficiency of the electric vehicle charger.

    본 발명에 따른 전기자동차의 충전 시간 단축을 위한 충전전류 제어 방법은 전기자동차의 충전 전압 및 제1 실제 충전 전류를 모니터링하는 단계, 상기 전기자동차의 제1 실제 충전 전류를 전기자동차 충전기에서 공급 가능한 기준 전류와 비교하는 단계, 상기 전기자동차의 제1 실제 충전 전류와 상기 전기자동차 충전기의 기준 전류가 상이한 경우, 상기 전기자동차에 충전 전류를 공급하는 상기 전기자동차 충전기의 제1 충전 허용 전류를 소정값 만큼 변화시키는 단계, 그리고 상기 소정값 만큼 변화된 제2 충전 허용 전류를 상기 전기자동차에 전송하고, 상기 제2 충전 허용 전류에 따른 상기 전기자동차의 제2 실제 충전 전류를 측정하여 상기 기준 전류와 비교하는 단계를 포함한다. 이를 통해서, 본 발명은 전기자동차의 충전 시간을 단축시키고, 전기자동차 충전기의 충전 효율을 향상시켜 충전시설 부족에 따른 문제를 해결할 수 있는 효과를 제공한다.
