Secondary battery cell groups and a fuse are formed in a second battery pack formed by the bridge connection of a secondary battery cell and the fuse. The secondary battery cell and the fuse are connected in a bridge mode. Each fuse is formed in the positive or negative terminal of the secondary battery cell. Therefore, each battery cell group of the present invention can be continuously operated when a temporary single battery cell is out of order. When a temporary battery cell among the secondary battery cells is out of order and a current flowing through the fuse exceeds a rate value, a fuse electrically connected to a broken secondary battery cell is cut to block a current. The stability of a battery pack can be improved by separating the broken secondary battery cell from good secondary battery cells. |
