The present invention relates to a control method of charge/discharge of an electric vehicle and, more specifically, to a method for efficiently, rapidly, and safely controlling charge/discharge of a battery by controlling charge/discharge data transfer between a charging control unit (CCU) and a battery management system (BMS) installed in an electric vehicle. Data is collected by forming a CAN communication channel with a CCU and a BMS installed in the electric vehicle, and the electric vehicle is charged at the lowest rate during light load time when being charged in a single-family house or a private workplace using the collected data.
본 발명은 전기 자동차 충방전 제어방법에 관한 것이다. 더욱 상세하게는, 전기자동차 내부에 설치되는 CCU(Charging Control Unit)와 BMS(Battery Manager System) 간 충방전 데이터 전송을 제어하여 효율적이고 신속하면서도 안전한 배터리 충방전을 제어하는 방법에 관한 것이다. 본 실시예에 의하면, 전기 자동차에 설치되는 CCU, BMS와 CAN 통신 채널을 형성하여 데이터를 수집하고, 수집된 데이터를 이용하여 단독주택, 개인 사업장에서 충전할 때, 경부하시간대 최저요금으로 충전할 수 있도록 하는 효과가 있다.
