Abstract

In a high-energy battery with a plurality of individual cells in a housing through which a coolant flows, it is suggested that the coolant be guided such that it thermally affects only one or both end faces of the cells.

Claims

1. High-energy battery for high operating temperatures, the battery comprising:

a housing;

a plurality of cells arranged next to one another in said housing, the cells each having a first end and a second end and side walls;

a liquid or gaseous medium flowing within the housing to influence the temperature of the individual cells; and

guide means for guiding the medium within the housing and for directing the medium such that only one of said first end and second end or both said first end and second end of the cells are brought directly or indirectly into heat-exchanging contact with the medium.

2. High-energy battery in accordance with claim 1, wherein said cells are formed as cylinders.

3. High-energy battery in accordance with claim 1, wherein said guide means acts on the medium to affect only one end of the cells.

4. High-energy battery in accordance with claim 1, wherein said guide means acts on the medium to affect only the two opposite ends of the cells.

5. High-energy battery in accordance with claim 1 wherein said guide means acts on the medium directing the medium directly around the ends of the cells.

6. High-energy battery in accordance with claim 1 wherein said guide means acts on the medium to thermally affect the ends of the cells indirectly, i.e., via an electrically insulating material.

7. High-energy battery in accordance with the claim 1 wherein said guide means includes one flow canal, which is arranged in parallel to a longitudinal direction of the cells, and in which means for affecting the temperature and/or the flow velocity of the medium are arranged, said flow canal being provided within said housing.

8. High-energy battery in accordance with the claim 1 wherein said guide means includes openings provided in said housing which permit the flow and/or the temperature to be influenced outside the housing at least temporarily and the medium to be replaced.

9. High-energy battery in accordance with the claim 1 wherein said guide means provides the medium located in the housing in a closed cycle at least part of the time.

10. A high-energy sodium based battery for high operating temperatures, the battery comprising:

a plurality of sodium cells, each cell being formed as a cylinder with side walls, and a top end and a bottom end, said cells being positioned within said housing to define an upper space adjacent top ends of said cells;

a fluid medium within said housing for flowing within said housing to influence a temperature of the individual cells; and

, fluid guide means for guiding the fluid medium within the housing for directing the fluid medium directly or indirectly into heat-exchanging contact with only said top surface of said cells.

11. A high-energy sodium based battery for high operating temperatures, the battery comprising:

a plurality of sodium cells, each cell being formed as a cylinder with side walls, and a top end and a bottom end, said cells being positioned within said housing to define an upper space adjacent top ends of said cells and defining a lower space adjacent bottom ends of the cells;

a fluid medium within said housing for flowing within said housing to influence a temperature of the individual cells; and

, fluid guide means for guiding the fluid medium within the housing such that each of the top surface of each of said cells and the bottom surface of each of said cells is brought directly or indirectly into heat-exchanging contact with the medium.
