본 개시에 따르면 배터리셀이 일정한 전압을 유지하도록 전류를 충전하는 충전부, 상기 배터리셀의 전압과 전류를 측정하는 측정부, 및 상기 측정부가 측정한 전류에 기초하여, 상기 배터리셀에 결함이 존재하는지 판단하는 제어부를 포함하는, 결함 배터리셀을 검출하는 장치를 제공하여, 결함 배터리셀을 높은 정확도로 검출할 수 있고, 검출에 소요되는 시간을 단축할 수 있으며, 검출에 필요한 공간도 절감할 수 있다. An apparatus and method for detecting a defective battery cell is proposed. The proposed apparatus includes a charger for supplying current to cause a battery cell to maintain a constant voltage, a measurement part for measuring the voltage and current of the battery cell, and a controller for determining whether a defect exists in the battery cell on the basis of the current measured by the measurement part, whereby the defective battery cell may be detected with high accuracy, a time required for the detection may be shortened, and a space required for the detection may also be reduced.
