Abstract

A battery and straps for a battery are disclosed. The battery according to various embodiments comprises a number of straps which connect a number of battery cells in series. The battery straps may pass through cutouts provided in a cell divider wall. The cutouts and straps may define a common headspace. The battery may have five connecting straps and two end straps.

First claim

The invention claimed is:

1. A battery having:
a cover;
a housing defining cells aligned in a single row, each cell divided by a cell wall having a respective cutout;
a plurality of battery elements provided within the cells;
two rows of battery straps connecting the plurality of battery elements in series, each connecting battery strap of the two rows extending through a respective cell wall of the cell walls through the respective cutout;
a vapor communicative common headspace above a surface of the cells, the vapor communicative common headspace defined by paths of open headspace proximate each respective battery strap and further defined by the cover; and
wherein each battery strap has a cross section that includes a substantially rectangular prism shape and is configured to taper from a bottom surface to a top surface of the strap.

2. The battery of claim 1 , wherein each cutout has a cutout width and each strap has a strap width and the cutout width is larger than the strap width.

3. The battery of claim 1 , wherein each cutout has a cutout height and each strap has have a strap height and the cutout height is larger than the strap height.

4. The battery of claim 1 , wherein the battery straps comprise five connecting straps.

5. The battery of claim 1 , wherein the battery straps comprise a first row having three connecting straps and a second row comprising two connecting straps.

6. A battery comprising:
a housing defining six cells aligned in a single row and having five cell walls separating the six cells, each cell wall having a cutout;
a first row of battery straps arranged above a surface of the single row of cells, the first row having a first connecting strap, a second connecting strap, and a third connecting strap;
a second row of battery straps arranged above the surface of the single row of cells, the second row having a fourth connecting strap and a fifth connecting strap;
the second row further comprising a first end strap and a second end strap;
the first, second, third, fourth, and fifth connecting straps directly connecting the six cells in series through the cell walls;
a vapor communicative common headspace for the six cells, the vapor communicative common headspace including a plurality of open spaces defined by the cutout and the connecting straps; and
wherein each connecting strap has a cross section that includes a substantially rectangular prism shape configured to taper from a bottom surface to a top surface of said strap.

7. The battery of claim 6 , wherein each connecting strap has a top surface with a front edge, a first side edge, a second side edge, and a back edge, the first side edge and the second side edge being parallel to each other and perpendicular to the front edge and the back edge.

8. The battery of claim 6 , wherein each connecting strap passes through a respective cutout to connect adjacent battery elements.

9. The battery of claim 6 , wherein each cutout has a cutout height which is larger than a connecting strap height.

10. The battery of claim 6 , wherein each cutout has a cutout width which is larger than a connecting strap width.

11. The battery of claim 1 , wherein each battery strap has a top surface with a front edge, a first side edge, a second side edge, and a back edge, the first side edge and the second side edge being parallel to each other and perpendicular to the front edge and the back edge.

12. The battery of claim 11 , wherein the top surface of each battery strap is continuous along the front edge and the first side edge.

13. The battery of claim 7 , wherein the top surface of each connecting strap is continuous along the front edge and the first side edge.
