Abstract

A cooling device is provided for a battery (1). The cooling device has a housing (3). To further improve the cooling of batteries, in particular of high-voltage batteries for hybrid vehicles or electric vehicles, the housing (3) has a liquid-cooling arrangement and an air-cooling arrangement. For winter operation, a heating unit is integrated.

Claims

1. A cooling device for a battery comprising a housing with an air-cooling arrangement and a liquid-cooling arrangement.

2. The cooling device of claim 1, wherein the cooling device comprises a first region having the air-cooling arrangement and a second region separate from the first region and having the liquid-cooling arrangement.

3. The cooling device of claim 2, further comprising a third region with a heating unit.

4. The cooling device of claim 3, wherein the cooling device is plate-shaped and the regions of the cooling device are formed as layers of the plate-shaped cooling device.

5. The cooling device of claim 4, further comprising battery cells arranged on the layer with the liquid-cooling arrangement.

6. The cooling device of claim 5, wherein the layer with the heating unit is arranged between the layer with the air-cooling arrangement and the layer with the liquid-cooling arrangement.

7. The cooling device of claim 6, wherein the heating unit is an electric heating unit.

8. The cooling device of claim 4, wherein the layer with the liquid-cooling arrangement comprises a liquid-cooling circuit.

9. A battery having the cooling device of claim 4.

10. A motor vehicle having the battery of claim 9.
