Zusammenfassung:	The present invention relates to a charging and discharging device fault diagnosis system and a fault diagnosis method using the same. According to the present invention, the charging and discharging device fault diagnosis system comprises: a charging and discharging device in which secondary batteries are arranged in at least one channel and which charges or discharges the secondary batteries arranged in each channel; a diagnostic device electrically connected to the charging and discharging device, differently setting a measurement condition according to a diagnosis mode, and measuring a voltage or a current of the charging and discharging device; and diagnosis control equipment controlling the diagnostic device and performing at least one of diagnosis for determining whether the charging and discharging device is faulty, diagnosis and correction for precision, and diagnosis for determining whether a measurement circuit is faulty, based on a voltage value of current value measured in the diagnostic device. 본 발명은 충방전기 고장 진단 시스템 및 이를 이용한 고장 진단 방법에 관한 것으로, 본 발명에 따른 충방전기 고장 진단 시스템은 2차전지가 적어도 하나 이상의 채널로 배열되고, 상기 채널별로 배열된 2차전지를 충전 또는 방전하는 충방전기, 상기 충방전기와 전기적으로 연결되고, 진단 모드에 따라 측정 조건을 다르게 설정하여 상기 충방전기의 전압 또는 전류를 측정하는 진단기 및 상기 진단기를 제어하고 상기 진단기에서 측정된 전압 값 또는 전류 값을 기초로 상기 충방전기의 고장 여부 진단, 정밀도 진단과 보정 및 측정 회로 고장 진단 가운데 적어도 하나 이상을 수행하는 진단 제어장비를 포함한다.
