The present invention relates to a battery pack including a cell switching device for a parallel-connected cell and a cell switching method, and more particularly, a battery pack including a cell switching device which can replace a faulty cell, when the faulty cell occurs due to an open parallel connection line or a CID operation among parallel-connected battery cells, with a normal replacement cell, and a cell switching method. The battery pack includes: a first cell bank configured by connecting a predetermined number of sequentially adjacent battery cells in parallel from the first cell among battery cells constituting a cell parallel line; and a second cell bank configured by connecting, in parallel, the remaining cells except for the battery cells set as the first cell bank among the battery cells constituting the cell parallel line.

    본 발명은 병렬 연결 셀의 셀 스위칭 장치를 포함하는 배터리 팩 및 셀 스위칭 방법에 관한 것으로서, 보다 구체적으로는 병렬 연결된 배터리 셀들 중 병렬 연결선 오픈 또는 CID 동작에 의한 고장 셀이 발생하는 경우, 상기 고장 셀을 정상적인 교체용 셀로 교체해주는 셀 스위칭 장치를 포함하는 배터리 팩 및 셀 스위칭 방법에 관한 것이다.
