Abstract
Provided is a battery module that offsets external power exerted on a rechargeable battery not only to protect the rechargeable battery but also to ensure security. The battery module includes: a casing which comprises an electrode assembly and has an open upper portion; a cap assembly which is disposed at an upper portion of the casing so as to seal the casing; and a first connection cap which is disposed on the cap assembly, wherein the first connection cap includes: a cap base which is fixed to the cap assembly and in which one or more indentations are formed at an outermost edge portion thereof; and a cover which protrudes from the cap base in an opposite direction of the cap assembly and has one or more openings at a lateral portion thereof.
Claims20
A battery module comprising:
- a casing which comprises an electrode assembly and defines an open upper portion;
- a cap assembly which is disposed at said upper portion of the casing so as to seal the casing;
- and
- a first connection cap which is disposed on the cap assembly and comprises a cap base and a cover;
- wherein said cap base is fixed to the cap assembly and comprises a rim and an indentation formed on the rim;
- wherein said cover comprises a side wall extending from the cap base away from the cap assembly;
- wherein said cover further comprises an opening through the side wall that is enclosed by the side wall;
- and
- wherein the rim includes a depressed portion for interconnecting the rim to the cap assembly and wherein the depressed portion is formed in the rim so that the depressed portion is positioned on the rim in front of the opening in the side wall and wherein the indentation in the rim is positioned in the rim so as to be offset from a corner of the opening in the side wall.
A method of manufacturing a battery module comprising the steps of:
- providing a casing which comprises an electrode assembly and defines an open upper portion;
- providing a cap assembly which is disposed at said upper portion of the casing so as to seal the casing;
- fixing a first connection cap onto the cap assembly, the first connection cap comprising a cap base and a cover;
- and
- fixing a second connection cap onto a lower surface of the casing;
- wherein said cap base is fixed to the cap assembly and comprises a rim and a plurality of indentations formed on the rim;
- wherein said cover comprises a side wall extending from the cap base away from the cap assembly;
- and
- wherein said cover further comprises a plurality of openings through the side wall that are enclosed by the side wall;
- and
- wherein the rim includes a plurality of depressed portions for interconnecting the rim to the cap assembly and wherein the depressed portions are formed in the rim so that the depressed portions are positioned on the rim in front of the plurality of openings in the side wall and wherein the plurality of indentations in the rim are positioned in the rim so as to be offset from a corner of the plurality of adjacent openings in the side wall.
