The present invention relates to a battery module inspection method. The battery module inspection method according to the present invention comprises: a first vision inspection process of inspecting a cell stack in which multiple battery cells are stacked, and inspecting the quantity and position of electrode leads provided in each of the plurality of battery cells using a vision camera; and a second vision inspection process of inspecting the quantity of the electrode leads provided in each of the plurality of battery cells and bent states of the electrode leads using the vision camera after going through the first vision process. During a battery module manufacturing process, the battery module inspection method can prevent false positives when inspecting a cell stack in which multiple battery cells are stacked. 본 발명은 전지 모듈 검사방법에 관한 것으로, 본 발명에 따른 전지 모듈 검사방법은 다수개의 전지셀이 적층된 셀 적층체를 검사하되, 다수개의 상기 전지셀에 각각 구비된 전극 리드의 수량 및 위치를 비젼 카메라를 통해 검사하는 제1 비젼 검사과정; 및 상기 제1 비젼 검사과정을 거친 후, 다수개의 상기 전지셀에 각각 구비된 전극 리드의 수량 및 꺾임 상태를 비젼 카메라를 통해 검사하는 제2 비젼 검사과정을 포함한다.
