Abstract

A battery having a plurality of voltage-generating cells which are arranged in particular adjacent to one another. The battery has a plurality of fastening/bearing points which are spaced apart from one another and on which the battery is fastened or bears. At least a first portion of the cells have a first mass, and optionally further include parts of the battery with an additional mass, and which come to rest between the fastening/bearing points. The first portion of the cells absorbs at least a substantial part of the bending/shear load arising in the battery between the fastening/bearing points. In addition, an I-shaped or H-shaped intermediate element is arranged between at least two voltage-generating cells.

Claims (33)

1. A battery comprising:

a plurality of voltage-generating cells;

a plurality of fastening points which are spaced apart from one another and on which the battery is fastened; and

an intermediate element arranged at least between adjacent voltage-generating cells to fix the adjacent voltage-generating cells to one another;

wherein the voltage-generating cells each have at least a first portion configured to absorb at least a predetermined portion of a bending/shear load arising in the battery between the fastening points, the first portion having a first mass arranged between the fastening points.

2. The battery of claim 1 , wherein at least two fastening points are spaced apart horizontally from one another and the battery is mounted in a substantially horizontal position to intentionally allow the first portion to absorb the predetermined portion of the bending/shear load resulting from an acceleration acting in a vertical direction on the first portion.

3. The battery of claim 1 , wherein at least two fastening points are spaced apart vertically from one another and the battery is mounted in a substantially vertical position to intentionally allow the first portion to absorb the predetermined portion of the bending/shear load resulting from an acceleration acting in a horizontal direction on the first portion.

4. The battery of claim 1 , wherein the predetermined portion comprises between 50% and 99.9% of the total bending/shear load arising in the battery when in motion.

5. The battery of claim 1 , wherein the first portion is configured to absorb the entire bending/shear load arising between the fastening points arising in the battery when in motion.

6. The battery of claim 1 , wherein an elastic rib contacts at least one of the voltage-generating cells to deform and provide length compensation, and a groove which together with the voltage-generating cell, defines a channel through which one of a gas or liquid flows and which absorbs heat from the voltage-generating cells.

7. The battery of claim 1 , wherein at least two adjacent voltage-generating cells and at least one intermediate element are adhesively bonded to one another.

8. The battery of claim 1 , wherein at least two adjacent voltage-generating cells and at least one intermediate element are mechanically fastened to one another.

9. The battery of claim 1 , further comprising tension elements configured to press at least two adjacent voltage-generating cells and at least one intermediate element against one another through the generation of a compressive preload.

10. The battery of claim 9 , wherein the tension elements comprises one of tension straps and tension rods.

11. The battery of claim 1 , further comprising a support element which spans at least two fastening points and which absorbs at least a portion of the bending/shear load not absorbed by the voltage-generating cells, wherein the support element is more fragile relative at least to the plurality of voltage-generating cells.

12. The battery of claim 11 , wherein the support element comprises a heat exchanger configured to absorb heat from the voltage-generating cells.

13. The battery of claim 11 , wherein the support element is located only at one side of the voltage-generating cells, wherein the support element is hollow and through which flows one of a gas and liquid which absorbs heat from the voltage-generating cells.

14. The battery of claim 1 , wherein the intermediate element has one of an I-shaped and H-shaped cross-section.

15. A battery comprising:

a plurality of voltage-generating cells;

a plurality of fastening points on which the battery is fastened; and

an intermediate element arranged at least between adjacent voltage-generating cells;

a support element configured to absorb at least a portion of a bending/shear load arising in the battery between the fastening points and also which absorb heat from the voltage-generating cells, wherein the support element is more fragile relative at least to the plurality of voltage-generating cells;

wherein the voltage-generating cells each have at least a first portion configured to absorb at least a portion of the bending/shear load.

16. The battery of claim 15 , wherein the support element is located only at one side of the voltage-generating cells, wherein the support element is hollow and through which flows one of a gas and liquid which absorbs heat from the voltage-generating cells.

17. The battery of claim 15 , further comprising tension elements configured to press at least two adjacent voltage-generating cells and at least one intermediate element against one another through the generation of a compressive preload.

18. The battery of claim 1 , wherein the intermediate element includes one or more of:

an element arranged only between edges of at least two adjacent voltage-generating cells;

an element arranged adjacent two or more sides of at least one adjacent voltage-generating cell; and

an element including a deformable elastic rib arranged adjacent at least one adjacent voltage-generating cell.

19. The battery of claim 18 , wherein the intermediate element includes:

a cross shaped element arranged only between an edge of a first adjacent voltage-generating cell, an edge of a second adjacent voltage-generating cell, an edge of a third adjacent voltage-generating cell, and an edge of a fourth adjacent voltage-generating cell an edge of a first adjacent voltage-generating cell;

a shell shaped element arranged adjacent three sides of a fifth adjacent voltage-generating cell and adjacent three sides of a sixth adjacent voltage-generating cell; and a plate shaped element including an elastic rib on two sides thereof to contact at least one of a seventh adjacent voltage-generating cell and an eight adjacent voltage-generating cell to deform and provide length compensation.
