Claim Text:
1. A battery pack having a plurality of electrically connected battery modules, the battery pack comprising an electrode terminal connecting device, wherein the electrode terminal connecting device comprises: a conductive connecting member coupled to electrode terminals of the battery modules to electrically connect the electrode terminals of the battery modules to each other, the conductive connecting member including opposite ends that protrude to form steps having a predetermined height, and a channel disposed between the opposite ends; an insulative sheathing member coupleable to the conductive connecting member and surrounding the conductive connecting member, the insulative sheathing member including at least one coupling member on an inside thereof having a tapered structure for securing to an opposite end of the conductive connecting member, and being open at a rear thereof to expose a region of the conductive connecting member between the opposite ends; and a shut-off cutter mounted to the conductive connecting member to shut off a circuit of the conductive connecting member when impact is applied to the battery pack in a longitudinal direction of the battery pack, the shut-off cutter being disposed adjacent the channel; wherein the shut-off cutter physically cuts the conductive connecting member when impact is applied to the battery pack in the longitudinal direction of the battery pack; and wherein the conductive connecting member is configured so that an upper end portion and a lower end portion of a region thereof corresponding to the shut-off cutter are depressed inward to a predetermined depth.
