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 - 18 . (canceled)

19 . 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 common headspace defined by the cell wall; and a battery strap cast onto two of the elements and directly connecting two of the elements in series through the cell wall, the battery strap configured to taper between a first and second surface of the strap.

20 . The battery of claim 19 , wherein the common headspace is defined at least in part by a cutout in the cell wall and the battery strap connects two elements through the cutout.

21 . The battery of claim 19 , wherein the battery strap comprises a first, second, third, fourth, and fifth connecting strap.

22 . The battery of claim 21 , 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.

23 . The battery of claim 22 , wherein the second row further comprises two end straps.

24 . The battery of claim 20 , wherein the cutout has a cross-sectional area which is larger than a cross-sectional area of the battery strap.

25 . The battery of claim 24 , wherein the common headspace is further defined by a difference between the cross-sectional area of the cutout and the cross-sectional area of the battery strap.

26 . 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 common headspace defined by the cutout; and a plurality of battery straps connecting the plurality of battery elements in series, each battery strap extending through a cell wall through a cutout, and each battery strap configured to taper between a first and second surface of the strap.

27 . The battery of claim 26 , wherein the cutout has a cutout width, and the battery straps have a strap width, and the cutout width is larger than the strap width.

28 . The battery of claim 26 , wherein the cutout has a cutout height, and the straps have a strap height, and the cutout height is larger than the strap height.

29 . The battery of claim 26 , wherein the battery straps comprise five connecting straps and two end straps.

30 . The battery of claim 29 , wherein the battery straps comprise a first row having three connecting straps and a second row comprising two connecting straps and two end straps.

31 . A battery comprising:
six cells, each cell provided with a plurality of battery elements and each cell being divided by a cell wall; seven connecting straps, the connecting 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.

32 . The battery of claim 31 , wherein each connecting strap is configured to taper between a first and second surface of the strap.

33 . The battery of claim 31 , wherein the cells are separated by five cell walls, each cell wall having a cutout, and wherein the common headspace is defined at least in part by the cutout in the cell wall.

34 . The battery of claim 33 , wherein each connecting strap passes through the cutout to connect adjacent battery elements.

35 . The battery of claim 33 , wherein each cutout has a cutout height which is larger than a connecting strap height.

36 . The battery of claim 33 , wherein each cutout has a cutout width which is larger than a connecting strap width.

37 . The battery of claim 33 , wherein each cutout has a cross-sectional area which is larger than a cross-sectional area of each connecting strap.

38 . The battery of claim 37 , wherein the common headspace is further defined by a respective difference between the cross-sectional area of each cutout and the cross-sectional area of each connecting strap.
