Battery module with improved frame structure and frame assembly therefor
The present disclosure provides a battery module including: at least one cell; and a frame assembly including a lower plate configured to support a lower end surface of the cell, a side plate extending perpendicularly from any opposite edge ends of the lower plate and placed adjacent to an outermost side of the cell, and an upper plate coupled to an upper end of the side plate to cover an upper portion of the cell.
1. A battery module comprising:
at least one cell; and
a frame assembly comprising a lower plate configured to support a lower end surface of the cell, a side plate extending perpendicularly from any opposite edge ends of the lower plate and placed adjacent to an outermost side of the cell, an upper plate coupled to an upper end of the side plate to cover an upper portion of the cell, a first guide plate extending perpendicularly from other opposite edge ends of the lower plate to prevent separation of the cell, and a second guide plate extending perpendicularly from an edge end of the upper plate to prevent separation of the cell,
wherein the first guide plate and the second guide plate are arranged opposite each other and are spaced from each other, and
wherein an edge of the upper plate is welded to the upper end of the side plate.
2. The battery module of claim 1 , wherein the first guide plate is bent from the lower plate in one piece with the lower plate.
3. The battery module of claim 1 , wherein the second guide plate is bent from the upper plate in one piece with the upper plate.
4. The battery module of claim 1 , wherein the side plate is bent from the lower plate in one piece with the lower plate.
5. The frame assembly of claim 1 , wherein an overall height of the first guide plate is less than an overall height of the side plates.
6. A frame assembly of a battery module for supporting at least one cell from an outside of the cell, the frame assembly comprising:
a lower plate configured to support a lower end surface of the cell;
a side plate perpendicularly extending from any opposite edge ends of the lower plate and placed adjacent to an outermost side of the cell;
an upper plate placed to cover an upper portion of the cell, opposite edge ends of the upper plate being coupled to an upper end of the side plate;
a first guide plate extending perpendicularly from other opposite edge ends of the lower plate to prevent separation of the cell; and
a second guide plate extending perpendicularly from an edge end of the upper plate to prevent separation of the cell,
wherein the first guide plate and the second guide plate are arranged opposite each other and are spaced from each other.
7. The frame assembly of claim 6 , wherein the edge ends of the upper plate are welded to the upper end of the side plate.
8. The frame assembly of claim 6 , wherein the first guide plate is bent from the lower plate in one piece with the lower plate.
9. The frame assembly of claim 6 , wherein the second guide plate is bent from the upper plate in one piece with the upper plate.
10. The frame assembly of claim 6 , wherein the side plate is bent from the lower plate in one piece with the lower plate.
