Patent ID: 8268474

Claim:
A battery module comprising: a plurality of unit cells spaced from one another in a first direction; and a plurality of cell barriers, each of the cell barriers being adjacent to a respective unit cell of the plurality of unit cells, wherein a cell barrier of the cell barriers comprises: a body member extending in a second direction and at least partially covering a first outer surface of the adjacent respective unit cell that is facing in the first direction, the body member having an opening extending in the second direction, the second direction being perpendicular to the first direction; and a bending element extending from a side of the body member in a third direction opposite the first direction and at least partially enclosing a second outer surface of the adjacent respective unit cell, wherein the bending element has an opening extending in the third direction and wherein a length of the opening in the third direction is greater than a thickness of the body member in the third direction, wherein the opening of the bending element and the opening of the body member together define a coolant flow path extending in the second direction from a first side of the adjacent respective unit cell to a second side of the adjacent respective unit cell opposite the first side.
