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

1 . A battery having:
a housing having at least two cells and a cell wall provided between the two cells; a plurality of elements provided within the cells; a battery strap cast onto two of the elements and directly connecting two of the elements in series through the cell wall; a common headspace defined by the cell wall; wherein the 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.

2 . The battery of claim 1 , wherein the common headspace is defined by a cutout in the cell wall and the battery strap connects two elements through the cutout.

3 . The battery of claim 1 , wherein the battery straps comprise a first, second, third, fourth, and fifth connecting strap.

4 . The battery of claim 3 , wherein the first, second, and third connecting strap are provided in a first row and the fourth and fifth connecting straps are provided in a second row opposite the first row.

5 . The battery of claim 4 , wherein the second row further comprises two end straps.

6 . The battery of claim 1 , wherein the cutout has a cutout width and the straps have a strap width and the cutout width is larger than the strap width.

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

8 . A battery having:
a housing having cells and cell walls, the cell walls each having a cutout; a plurality of battery elements provided within the cells; a plurality of battery straps connecting the plurality of battery elements in series, each battery strap extending through a cell wall through a cutout; a common headspace defined by the cutout; wherein the 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.

9 . The battery of claim 8 , wherein the cutout has a cutout width and the straps have a strap width and the cutout width is larger than the strap width.

10 . The battery of claim 8 , wherein the cutout has a cutout height and the straps have a strap height and the cutout height is larger than the strap height.

11 . The battery of claim 8 , wherein the battery straps comprise five connecting straps and two end straps.

12 . The battery of claim 11 , wherein the battery straps comprise a first row having three connecting straps and a second row comprising two connecting straps and two end straps.

13 . A battery comprising:
six cells, each cell being divided by a cell wall; seven straps, the straps being arranged in two rows, a first row having a first connecting strap, a second connecting strap, and a third connecting strap; a 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; and a common headspace defined by the cell walls.

14 . The battery of claim 13 , wherein the 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.

15 . The battery of claim 13 , wherein the cells are separated by five cell walls, each cell wall having a cutout.

16 . The battery of claim 15 , wherein each connecting strap passes through the cutout to connect adjacent battery elements.

17 . The battery of claim 15 , wherein each cutout has a cutout height which is larger than a connecting strap height.

18 . The battery of claim 15 , wherein each cutout has a cutout width which is larger than a connecting strap width.
