Abstract

Described herein is an electrochemical energy store including at least one electrochemical cell and a support structure, wherein the electrochemical cells are accommodated in a suspended manner in the support structure.

First claim

The invention claimed is:

1. An electrochemical energy store comprising at least one electrochemical cell and a support structure, wherein the at least one electrochemical cell is accommodated in a suspended manner in the support structure and the support structure together with the at least one electrochemical cell accommodated therein in a suspended manner is enclosed by a housing, wherein the housing has an inlet and an outlet for a temperature control medium, wherein the support structure comprises at least one frame with a holding device, in which the at least one electrochemical cell is suspended, and the holding device is a plate, in which cut-outs in which the at least one electrochemical cell is hung have been formed, wherein the cut-outs further are configured such that the temperature control medium flows uniformly through the housing in which the support structure is accommodated.

2. The electrochemical energy store according to claim 1 , wherein the cut-outs each comprise an opening, a slot adjoining the opening, and a bracket which includes an angle to a surface of the plate in a range from 45 to 180, with the bracket being arranged on a side of the opening facing the slot.

3. The electrochemical energy store according to claim 1 , wherein the at least one electrochemical cell each have a suspension which at an end of the suspension facing away from the electrochemical cell has a bracket bent through at least 90°.

4. The electrochemical energy store according to claim 3 , wherein the suspension of the at least one electrochemical cell has been passed through a slot and rests with the bracket bent through 90° on a plate.

5. The electrochemical energy store according to claim 1 , wherein the support structure comprises a main framework having rails onto which at least one frame has been pushed.

6. The electrochemical energy store according to claim 1 , wherein the at least one electrochemical cell each have a spacer at a lower end of the at least one electrochemical cell.

7. The electrochemical energy store according to claim 1 , wherein the inlet and the outlet are arranged so that the temperature control medium flows from a top downward along the at least one electrochemical cell.

8. The electrochemical energy store according to claim 1 , wherein the inlet for the temperature control medium is arranged above the holding device.

9. The electrochemical energy store according to claim 1 , wherein a channel to which the inlet and the outlet for the temperature control medium are connected outside a housing is provided, with a heat exchanger and a transport device for the temperature control medium being accommodated in the channel.

10. The electrochemical energy store according to claim 1 , wherein the at least one electrochemical cell is sodium-sulfur cells.
