The present invention relates to a redox flow battery charging system and method for charging electric vehicles which utilize eco-friendly power generation or idle power in the midnight. The redox flow battery charging system comprises: a distribution board through which commercial AC power enters a building from a power system; an eco-friendly power generation module connected to the distribution board; a two-way power conversion module connected to the distribution board; a battery unit installed in a predetermined building and including a redox flow battery which is charged by receiving direct current power output from the eco-friendly power generation module or the power conversion module; a battery management module monitoring status information of the redox flow battery; and an energy management module receiving the status information of the battery unit, diagnosing a status of the battery unit based on the received status information, and controlling each operation of the power conversion module and the battery management module. According to an embodiment of the present invention, the redox flow battery, which is easy to install and maintain, can be charged using solar power and midnight electricity and can be used to charge electric vehicles or for various power needed in small buildings or homes. 본 발명은 친환경 발전 또는 심야의 유휴 전력을 활용하는 전기자동차 충전용 레독스 흐름전지 충전 시스템 및 방법에 관한 것으로, 전력계통으로부터 건물로 상용 교류전력이 인입되는 분전반; 상기 분전반에 접속된 친환경 발전 모듈; 상기 분전반에 접속된 상기 분전반에 접속되는 양방향 전력변환모듈과; 소정 건물 내에 설치되며, 상기 친환경 발전 모듈 또는 전력변환 모듈로부터 출력되는 직류전력을 공급받아 충전되는 레독스 흐름전지를 포함한 배터리유닛과; 상기 레독스 흐름전지의 상태정보를 모니터링하는 배터리관리모듈; 상기 배터리유닛의 상태정보를 수신하고, 수신된 상태정보를 기반으로 상기 배터리유닛의 상태를 진단하며, 상기 전력변환모듈 및 상기 배터리관리모듈의 동작을 각각 제어하는 에너지관리모듈을 포함한다. 본 발명의 실시예에서는, 설치 및 유지보수가 편리한 레독스 흐름전지를 태양광 및 심야전기를 이용하여 충전하고, 전기차 충전 또는 소형 건물이나 가정에서 필요한 다양한 전력에 사용할 수 있다.
