Abstract
A battery module includes: battery cells arranged in a first direction that include vent portions; and a first module case extending in the first direction and supporting the battery cells. The first module case includes a first vent flow path communicating with the vent portions, and projecting away from the battery cells and extending in the first direction, and second vent flow paths spaced from each other in a second direction traversing the first direction, extending in the first direction to support the battery cells, and directly communicating with the first vent flow path. The first vent flow path is between the second vent flow paths.
Claims18
A battery module comprising:
- a plurality of battery cells arranged in a first direction, the plurality of battery cells comprising a plurality of vent portions;
- and
- a first module case extending in the first direction and supporting the plurality of battery cells,
- wherein the first module case comprises:
- a first vent flow path in communication with the plurality of vent portions, the first vent flow path projecting away from the plurality of battery cells and extending in the first direction, and
- a plurality of second vent flow paths spaced from each other in a second direction traversing the first direction, the plurality of second vent flow paths extending in the first direction to support the battery cells, and directly communicating with the first vent flow path, wherein the first vent flow path is between the plurality of second vent flow paths;
- a battery insulating sheet between the plurality of battery cells and the first module case, the battery insulating sheet comprising a plurality of sheet through-holes corresponding to the plurality of vent portions;
- a heat insulating sheet between the battery insulating sheet and the first module case, the heat insulating sheet being attached to the first vent flow path;
- a first cover covering each second vent flow path of the plurality of second vent flow paths and supporting the battery cells, wherein the first vent flow path is uncovered by the first cover;
- and
- through-holes in the first cover facing the plurality of battery cells, the through-holes communicating with the second vent flow path, wherein the through-holes in the first cover are spaced apart from the first vent flow path in the second direction.
