Abstract
A battery module includes a battery unit having a plurality of batteries; a pair of end plates, one of the end plates installed at either end of the battery unit; and a fixing band that encircles the end plates and the battery unit, wherein the fixing band is made from a material that expands when heated and contracts when cooled.
Claims13
A battery module comprising:
- a battery unit comprising a plurality of batteries;
- a pair of end plates, one of the end plates installed at either end of the battery unit, wherein each of the end plates has an accommodation groove extending in a first direction and an end face, wherein the end face and the accommodation groove are formed entirely in an arc protruding away from the battery unit;
- and
- a fixing band oriented in and continuously contacting the accommodation groove in the first direction so as to encircle the end plates and the battery unit, the fixing band having a first end and a second end and being entirely continuous, wherein the first end and the second end abut each other, and wherein the fixing band comprises a material that expands when heated and contracts when cooled.
