Abstract

The invention relates to a device for holding power storage assemblies ( 3 ), arranged side by side in a power storage module, in position, the device including: a plate ( 1 ) made of an electrically insulating material and extending along a main plane (P); recesses ( 2 ) provided in the plate, wherein each recess is to receive a respective power storage assembly such that the longitudinal axis of the storage assembly extends perpendicular to the main plane (P); and at least one holder made of an insulating material and intended for receiving an electrical connection means for electrically connecting at least one power storage assembly to an electronic board of the module.

First claim

The invention claimed is:

1. A device for supporting power storage assemblies positioned side by side in a power storage module, the device including:
a plate made of an electrically insulating material and extending along a principal plane,
recesses formed in the plate, each recess for accommodating a respective power storage assembly, so that the longitudinal axis of the storage assembly extends essentially perpendicular to the principal plane, each recess having a through opening,
at least one support made of electrically insulating material for accommodating electrical connection means for electrically connecting at least one power storage assembly to an electronic card of the module,
wherein the shape of each of the through openings corresponds to the cross-section shape of the respective electrical power storage assembly taken at the level of its lateral face in its central portion, the dimensions of the through opening being such that said through opening allows nesting by force of the respective power storage assembly into said opening,
wherein the device includes a base for accommodation of the electronic card of the module and attachment means for attaching the electronic card to said base, this base comprising a panel extending perpendicularly to the plate at one of the ends thereof and such that it extends to either side of the plate, the support, the plate and the base being a single unit.

2. The device according to claim 1 , wherein the, or at least one of the supports includes at least one chamber extending essentially perpendicular to the plate, each chamber being suitable for accommodating a respective electrical connection plug.

3. The device according to claim 2 , wherein each chamber is open at one end and includes a tie for attaching the electrical connection plug.

4. The device according to claim 1 , wherein the, or at least one of the supports includes guide means made of electrically insulating material extending toward the outside of the plate for guiding along a passage channel a cable provided on the device, a least one connecting cable capable of electrically connecting at least one storage assembly to the electronic card.

5. The device according to claim 4 , wherein the guide means include two fingers extending perpendicular to the plate and positioned on either side of the cable passage channel.

6. The device according to claim 5 , wherein each finger includes an excrescence extending parallel to the plate in the direction of the cable passage channel so as to allow clipping and support of the cable between said fingers.

7. The device according to claim 1 , wherein the, or at least one of the supports is integrated with the plate, the electrical connection means being embedded in the assembly consisting of the support and of the plate.

8. The device according to claim 1 , wherein each recess also includes at least one shimming wall for shimming and centering the device on the power storage assemblies, said shimming wall being positioned at the opening and extending perpendicular to the plate.

9. The device according to claim 8 , said device also includes at least one shank extending perpendicular to the plate over one of its faces, said shank being suitable for coming into contact with a wall of the power storage module to allow shimming of the device within the power storage module.

10. The device according to claim 1 , said device also includes coupling means located at the edge of the plate for fastening said device to another supporting device according to one of the preceding claims.

11. The device according to claim 1 , said device also includes means for attaching a sensor on the device.

12. The device according to claim 1 , said device also includes at least one wall essentially perpendicular to the plate and at the edge of the plate to electrically isolate the power storage assemblies from the walls of the power storage module.

13. The device according to claim 1 , including means extending essentially perpendicular to the principal plane for guiding reinforcements intended to link two opposite walls of the module.

14. The device according to claim 1 , characterized in that it integrates:
at least one electronic card, and/or
at least one electrical connection plug at a terminal of an assembly, and/or
at least one connection plug to the electronic card, and/or
at least one connecting cable for connecting the terminal of the assembly to the electronic card, and/or
at least one sensor.

15. A power storage module including a housing wherein are arranged at least two electrical power storage assemblies, wherein the module includes a supporting device for supporting power storage assemblies positioned side by side in a power storage module, the device including:
a plate made of an electrically insulating material and extending along a principal plane,
recesses formed in the plate, each recess for accommodating a respective power storage assembly, so that the longitudinal axis of the storage assembly extends essentially perpendicular to the principal plane, each recess including a through opening,
at least one support made of electrically insulating material for accommodating electrical connection means for electrically connecting at least one power storage assembly to an electronic card of the module,

each assembly being positioned in a respective opening and protruding from the plate of the device on either side thereof,
wherein a shape of each of the through openings corresponds to the cross-section shape of the respective electrical power storage assembly taken at the level of its lateral face in its central portion, the dimensions of the through opening being such that said through opening allows nesting by force of the respective power storage assembly into said opening, the respective power storage assembly extending to either side of the opening, wherein the supporting device includes a base for accommodation of the electronic card of the module and attachment means for attaching the electronic card to said base, this base comprising a panel extending perpendicularly to the plate at one of the ends thereof and such that it extends to either side of the plate, the support, the plate and the base being a single unit.

16. The module according to claim 15 , wherein the, or at least two adjoining assemblies are electrically connected by means of a connection link positioned on two end faces of the assemblies and extending essentially parallel to the plate when the assemblies are placed in the supporting device, wherein the device includes a connection plug positioned in the chamber, said connection plug being able to cooperate with a tongue situated protruding from the connection link, essentially perpendicular to the link.

17. A method for manufacturing a module including a housing wherein are arranged at least two electrical power storage assemblies, wherein the module includes a supporting device for supporting power storage assemblies positioned side by side in a power storage module, the supporting device including:
a plate made of an electrically insulating material and extending along a principal plane,
recesses formed in the plate, each recess being suitable for accommodating a respective power storage assembly, so that the longitudinal axis of the storage assembly extends essentially perpendicular to the principal plane, each recess having a through opening, wherein the shape of each of the through openings corresponds to the cross-section shape of the respective electrical power storage assembly taken at the level of its
