Abstract

The invention relates to a cover for covering a tubular element of a first electrical energy storage assembly (20), said cover comprising a covering wall (50). The cover is characterized in that it comprises a radially extending electroconductive tongue (60, 70) comprising a contact face (71) intended to come into contact with a second adjacent storage assembly in order to electrically connect the two storage assemblies.

First claim

The invention claimed is:

1. A cover intended to cap a tubular element of a first electrical energy storage assembly, the cover comprising a covering wall and at least one side wall essentially normal to the covering wall, wherein the cover comprises an electrically conductive radial tongue arranged on said at least one side wall, said tongue extending radially on its entire length from said side wall, said radial tongue having a contact face located at a free end of the radial tongue, essentially normal to the covering wall and of a concave shape, said contact face being intended to come into contact and to match with the cover or a tubular element of a second adjacent storage assembly to connect the two storage assemblies electrically together.

2. The cover according to claim 1 also comprising a peripheral skirt extending over the periphery of the covering wall, the radial tongue being arranged on the peripheral skirt.

3. The cover according to claim 1 forming a disc comprising the covering wall, the radial tongue being arranged on a side wall of the disc.

4. The cover according to claim 1 , wherein the ends of the radial tongue in a direction normal to the covering wall are located between the ends of the remainder of the cover in this direction.

5. The cover according to claim 4 , wherein the ends of the radial tongue in at least one other direction along the plane of the covering wall are located between the ends of the covering wall in this direction.

6. An energy storage assembly comprising a tubular element having a side face and at least one cover intended to cap one of the ends of the tubular element, the cover comprising a covering wall intended to cover said end of the tubular element and at least one side wall essentially normal to the covering wall, the cover comprising an electrically conductive radial tongue arranged on said at least one side wall, said tongue extending radially on its entire length from said side wall, said radial tongue having a contact face located at a free end of the radial tongue, essentially normal to the covering wall and of a concave shape, said contact face being intended to come into contact and to match with the cover or a tubular element of a second adjacent storage assembly to connect the two storage assemblies electrically together.

7. The assembly according to claim 6 , wherein the cover forms a disc comprising the covering wall, the radial tongue being arranged on a side wall of the disc, and is intended to be inserted in the tubular element, the tubular element comprising a cut-out whose shape matches the shape of the cross-section of the radial tongue in its side wall to allow the radial tongue to pass.

8. The assembly according to claim 6 wherein the cover comprises a peripheral skirt extending over the periphery of the covering wall, the radial tongue being arranged on the peripheral skirt, the peripheral skirt being intended to surround the side face of the tubular element.

9. A module comprising at least two electrical energy storage assemblies, wherein at least one of the assemblies is an assembly comprising a tubular element having a side face and at least one cover intended to cap one of the ends of the tubular element, the cover comprising a covering wall intended to cover said end of the tubular element and at least one side wall essentially normal to the covering wall, the cover comprising an electrically conductive radial tongue arranged on said at least one side wall, said tongue extending radially on its entire length from said side wall, said radial tongue having a contact face located at a free end of the radial tongue, essentially normal to the covering wall and of a concave shape, said contact face coming into contact, matching with and being secured with the cover or with the tubular element of a second adjacent storage assembly to connect the two storage assemblies electrically together, the or at least one of the radial tongues of said cover or covers forming a connecting body allowing the electrical connection of the two assemblies.

10. The module according to claim 9 , wherein the storage assembly or assemblies are configured so that the connecting body extends between the two storage assemblies so that the height of each storage assembly connected to the connecting body is equal to the height of a storage assembly not connected to a connecting body.

11. The module according to claim 9 wherein the two storage assemblies comprise a tubular element having a side face and at least one cover intended to cap one of the ends of the tubular element, the cover comprising a covering wall intended to cover said end of the tubular element and at least one side wall essentially normal to the covering wall, the cover comprising an electrically conductive radial tongue arranged on said at least one side wall, said tongue extending radially on its entire length from said side wall, said radial tongue having a contact face located at a free end of the radial tongue, essentially normal to the covering wall and of a concave shape, said contact face coming into contact, matching with and being secured with the cover or with the tubular element of a second adjacent storage assembly to connect the two storage assemblies electrically together, and wherein the connecting body comprises two radial tongues each forming a portion of the connecting body, each radial tongue being in a single piece with a cover of each respective assembly, said radial tongues being positioned on the assemblies so that they are superimposed during the electrical connecting of said assemblies.

12. The module according to claim 11 , wherein one of the radial tongues forming the connecting body is thicker than the other of the radial tongues forming the connecting body.

13. The module according to claim 11 wherein each portion of the connecting body is connected to the assembly from which it is separate, via welding.

14. The module according to claim 11 , wherein each cover of each assembly forms a disc comprising the covering wall, the radial tongue being arranged on a side wall of the disc, and is intended to be inserted in the tubular element, the tubular element comprising a cut-out whose shape matches the shape of the cross-section of the radial tongue in its side wall to allows the radial tongue to pass.

15. The module according to claim 11 , wherein each cover of each assembly comprises a peripheral skirt extending over the periphery of the covering wall, the radial tongue being arranged on the peripheral skirt, the peripheral skirt being intended to surround the side face of the tubular element.

16. The module according to claim 9 , wherein the at least one cover of the assembly forms a disc comprising the covering wall, the radial tongue being arranged on a side wall of the disc, and is intended to be inserted in the tubular element, the tubular element comprising a cut-out whose shape matches the shape of the cross-section of the radial tongue in its side wall to allows the radial tongue to pass.

17. The module according to claim 9 , wherein the at least one cover of the assembly comprises a peripheral skirt extending over the periphery of the covering wall, the radial tongue being arranged on the peripheral skirt, the peripheral skirt being intended to surround the side face of the tubular element.

18. A method for assembling a module comprising at least two electrical energy storage assemblies wherein at least one assembly comprises a tubular element having a side face and at least one cover intended to cap one of the ends of the tubular element,
