Abstract

A multi-cell battery includes a battery box having at least three battery plate compartments, wherein the plates in one compartment lie in planes substantially perpendicular to plates in the other two compartments. The compartments can be of rectangular shape and arranged with the length direction of one compartment substantially perpendicular to the length direction of the other two compartments.

Claims

1. A multi-cell battery comprising a battery box comprising at least three battery plate compartments, wherein the plates in one compartment lie in planes substantially perpendicular to plates in the other two compartments and the plates of said other two compartments are connected electrically in series via the plates of said one compartment, wherein said other two compartments lie side-by-side, and wherein each said compartment is of rectangular shape and the length direction of said one compartment is equal to the sum of the widths of said other two compartments and the thickness of the partition wall(s) between the side-by-side compartments.

2. A battery according to claim 1, wherein, in use, the plates in said one compartment lie perpendicular relative to the plates in said other two compartments when viewed in plan.

3. A battery according to claim 1 wherein the battery box comprises at least one additional pair of battery plate compartments.

4. A battery according to claim 3, wherein said additional pair of compartments comprises two compartments arranged side-by-side and aligned with, said other two compartments.

5. A battery box for a multi-cell battery and comprising at least three battery plate compartments each of rectangular shape and arranged with the length direction of one compartment substantially perpendicular to the length direction of the other two compartments, wherein said other two compartments lie side-by-side adjacent one another and said one compartment has a longer side thereof arranged adjacent end sides of said other two compartments, and wherein the length direction of said one compartment is equal to the sum of the widths of said other two compartments and the thickness of the first partition wall.

6. A battery box according to claim 5, wherein the box comprises a first partition wall that serves as a boundary between the two compartments that lie side-by-side.

7. A battery box according to claim 5, wherein the box comprises a second partition wall that serves as a boundary between said one compartment that said other two compartments.

8. A battery box according to claim 5, wherein said three battery plate compartments are of the same width and length dimensions.

9. A battery box according to claim 5, and comprising a cover adapted to extend over the battery cell compartments.

10. A battery box according to claim 9, wherein the cover is sealable to allow the compartments to contain electrolyte at a pressure greater than atmospheric pressure.

11. A multi-cell battery comprising a battery box comprising at least three substantially rectangular battery plate compartments, each of the compartments having a length dimension and a width dimension that differs from the length dimension, wherein the plates in one compartments lie in planes substantially perpendicular to plates in the other two compartments and the plates of said other two compartments are directly connected electrically in series via the plates of said one compartment, wherein, when viewed in plan, in a plane perpendicular to the plates of the three compartments, all three of said battery plate compartments are of the same width and length dimensions.

12. A battery according to claim 11, wherein said other two compartments lie side-by-side.

13. A battery according to claim 12, wherein the length direction of said one compartment is equal to the sum of the widths of said other two compartments and the thickness of the partition wall(s) between the side-by-side compartments.

14. A multi-cell battery comprising a battery box comprising at least three substantially rectangular battery plate compartments, each of the compartments having a length dimension and a width dimension that differs from the length dimension, wherein the plates in one compartment lie in planes substantially perpendicular to plates in the other two compartments and the plates of said other two compartments are connected electrically in series via the plates of said one compartment, wherein, when viewed in plan, in a plane perpendicular to the plates of the three compartments, all three of said battery plate compartments are of the same width and length dimensions, and said other two compartments lie side-by-side.

15. A battery according to claim 14, wherein the length direction of said one compartment is equal to the sum of the widths of said other two compartments and the thickness of the partition wall(s) between the side-by-side compartments.

16. A battery according to claim 14 wherein the battery box comprises at least one additional pair of battery plate compartments.
