Abstract
A rechargeable battery module includes unit cells that are arranged in a first direction, a bus bar that electrically connects the unit cells, a pair of end plates that are spaced apart from each other along the first direction at opposite ends of the unit cells to support the unit cells, and at least one side plate between the pair of end plates and connected to the pair of end plates, the at least one side plate extending along the unit cells and spaced apart from the unit cells a predetermined distance, wherein the side plate includes a stepped portion facing the unit cells.
Claims14
A rechargeable battery module, comprising:
- unit cells arranged in a first direction;
- a bus bar that electrically connects the unit cells;
- a pair of end plates spaced apart from each other along the first direction at opposite ends of the unit cells to support the unit cells;
- and
- at least one side plate between the pair of end plates and connected to the pair of end plates, the at least one side plate extending along the unit cells and spaced apart from the unit cells a predetermined distance,
- wherein the at least one side plate includes:
- stepped portions facing the unit cells, the stepped portions including a flat base at an outermost side of the at least one side plate, and at least one protruding portion that protrudes toward the unit cells from the flat base along a second direction crossing the first direction, and
- a through-hole adjacent to the unit cells, and
- wherein an insulating sheet is adhered to the at least one protruding portion and adjacent to the unit cells.
A rechargeable battery module, comprising:
- unit cells arranged in a first direction;
- a bus bar that electrically connects the unit cells;
- a pair of end plates spaced apart from each other along the first direction at opposite ends of the unit cells to support the unit cells;
- and
- at least one side plate between the pair of end plates and connected to the pair of end plates, the at least one side plate extending along the unit cells and spaced apart from the unit cells a predetermined distance,
- wherein the at least one side plate includes stepped portions facing the unit cells, and
- wherein the stepped portions include:
- a flat base at an outermost side of the at least one side plate, the flat base being parallel with the at least one side plate, and
- at least one protruding portion that protrudes toward the unit cells from the flat base along a second direction crossing the first direction, a first edge of the at least one protruding portion being connected to the flat base, and a second edge of the at least one protruding portion being opposite the first edge and spaced apart from the unit cells along the second direction to have an empty space therebetween.
