Abstract

An energy storage arrangement includes an energy storage receptacle which has multiple cup-shaped receiving compartments and energy storages respective positive and a negative electrode and being received in the receiving compartments, wherein one of the electrodes of each of the energy storages is in electrically conductive contact with the receiving compartment that receives the respective energy storage and the electrodes of all energy storages that are in contact with the energy storage receptacle are electrically conductively connected via the energy storage receptacle.

First claim

What is claimed is:

1. An energy storage arrangement, comprising:
an energy storage receptacle having multiple cup-shaped receiving compartments;
energy storages received in the receiving compartments, said energy storages each having a positive and a negative electrode, with one of the positive and negative electrodes of each of the energy storages being in electrically conductive contact with an associated one of the receiving compartments via a contact tab, wherein the contact tabs of the electrodes of all energy storages are electrically conductively connected in parallel with each other via the energy storage receptacle, wherein the energy storages are received directly in the energy storage receptacle without a separate housing surrounding each of the energy storages; and
a plurality of cover elements which electrically insulatingly close each receiving compartment individually relative to the energy storage receptacle, each said cover element having a connecting section, wherein another one of the negative and positive electrodes that is not in contact with the energy storage receptacle is electrically conductively connected with the cover element, wherein the connecting section of each of said cover element is surrounded by an insulating ring which electrically insulates the connecting section from the energy storage receptacle.

2. The energy storage arrangement of claim 1 , wherein the receiving compartments are separate from each other and a respective single one of the energy storages is received in each of the receiving compartments.

3. The energy storage arrangement of claim 1 , wherein the receiving compartments are connected to each other, with all of the energy storages being received in the connected receiving compartments.

4. The energy storage arrangement of claim 1 , wherein the one of the positive and negative electrodes of each of the energy storages is in electrically conductive contact with a bottom of the respective receiving compartment.

5. The energy storage arrangement of claim 1 , wherein the energy storage receptacle is produced in one piece by deep drawing of a sheet metal part.

6. The energy storage arrangement of claim 1 , wherein a respective geometric shape of the receiving compartments corresponds at least in regions to a geometric shape of the energy storages received in the receiving compartments.

7. A motor vehicle, comprising:
an energy storage compartment, said energy storage compartment comprising an energy storage receptacle having multiple cup-shaped receiving compartments, and energy storages received in the receiving compartments, said energy storages each having a positive and a negative electrode, with one of the positive and negative electrodes of each of the energy storages being in electrically conductive contact with an associated one of the receiving compartments via a contact tab, wherein the contact tabs of the electrodes of all energy storages are electrically conductively connected in parallel with each other via the energy storage receptacle, wherein the energy storages are received directly in the energy storage receptacle without a separate housing surrounding each of the energy storages, and a plurality of cover elements which electrically insulatingly close each receiving compartment individually relative to the energy storage receptacle, each said cover element having a connecting section, wherein another one of the negative and positive electrodes that is not in contact with the energy storage receptacle is electrically conductively connected with the cover element, wherein the connecting section of each of said cover element is surrounded by an insulating ring which electrically insulates the connecting section from the energy storage receptacle.

8. A method, comprising:
forming multiple receiving compartments in a sheet metal part by deep drawing;
placing energy storages in the multiple receiving compartments, respectively to produce an energy storage receptacle for an energy storage arrangement;
electrically conductively contacting an electrode of each of the energy storages with the receiving compartments via a contact tab such that the electrodes of all energy storages are electrically conductively connected in parallel with each other via the energy storage receptacle,
wherein the energy storages are received directly in the energy storage receptacle without a separate housing surrounding each of the energy storages,
electrically insulatingly closing each receiving compartment individually relative to the energy storage receptacle with a cover element, each said cover element having a connecting section, wherein another one of the negative and positive electrodes that is not in contact with the energy storage receptacle is electrically conductively connected with the cover element, wherein the connecting section of each of said cover element is surrounded by an insulating ring which electrically insulates the connecting section from the energy storage receptacle.

9. The method of claim 8 , wherein regions of the sheet metal part that do not form a part of the receiving compartments have a smaller material thickness than regions of the sheet metal part that form a part of the receiving compartments.

10. The method of claim 8 , wherein the receiving compartments are formed separate in the sheet metal part for receiving a respective single energy storage.

11. The method of claim 8 , wherein the receiving compartments are formed in the sheet metal part so as to be connected for receiving all of a plurality of energy storages.

12. The method of claim 8 , wherein the receiving compartments are formed so that at least regions of the receiving compartments have a geometric shape which corresponds to a geometric shape of energy storages to be received in the receiving compartments.
