Abstract
Official abstract text for this publication.
A battery module includes: a plurality of rechargeable batteries electrically connected in series with each other, each including a short-circuit member that is deformable according to an increase of an internal pressure; and a fuse member including a connection plate overlapping the short-circuit member and a fuse including a first end connected with the connection plate and a second end connected with a first electrode or a second electrode of one of a first rechargeable battery and a second rechargeable battery located at an end along the plurality of rechargeable batteries.
First claim
Opening claim text (preview).
What is claimed is: 1 . A battery module comprising: a plurality of rechargeable batteries electrically connected in series with each other, each comprising a short-circuit member that is deformable according to an increase of an internal pressure; and a fuse member including a connection plate overlapping the short-circuit member and a fuse including a first end connected with the connection plate and a second end connected with a first electrode or a second electrode of one of a first rechargeable battery and a second rechargeable battery located at an end along the plurality of rechargeable batteries. 2 . The battery module of claim 1 , wherein the fuse member is connected with the second electrode of the second rechargeable battery. 3 . The battery module of claim 1 , wherein the fuse is narrower than a width of a portion of the fuse member connected with the connection plate. 4 . The battery module of claim 1 , further comprising: a first draw-out tab connected with the first electrode of the first rechargeable battery; and a second draw-out tab connected with the fuse member. 5 . The battery module of claim 1 , wherein the battery module comprises at least one unit group, each including an odd number of rechargeable batteries of the plurality of rechargeable batteries. 6 . The battery module of- claim 5 ; wherein the fuse member includes one or more fuse members overlapping a short-circuit member of a rechargeable battery included in each unit group. 7 . The battery module of claim 8 , wherein the connection plate of each of the one or more fuse members overlaps the short-circuit member of a second rechargeable battery located at an end of the rechargeable batteries included in each of the unit groups. 8 . The battery module of claim 1 , wherein the rechargeable battery comprises an electrode assembly including a positive electrode and a negative electrode and configured to perform charging and discharging, a case in which the electrode assembly is installed, and a cap plate combined to the case, and wherein the cap plate and the first electrode are electrically connected with the positive electrode, and the second electrode is electrically connected with the negative electrode. 9 . The battery module of claim 8 , wherein the cap plate has a shape of a plate having a length direction and a width direction, and the short-circuit member is arranged closer to a center of the length direction of the cap plate than the second electrode. 10 . The battery module of claim 8 , wherein the cap plate comprises a short-circuit hole penetrating the cap plate, and the short-circuit member comprises an edge portion fixed to the cap plate in the short-circuit hole. 11 . The battery module of claim 10 , wherein the connection plate comprises protrusions protruded toward the short-circuit hole.
