Abstract

The invention relates to a battery system comprising at least one battery. According to the invention, provisions are made that said battery system comprises at least one Peltier element, which is used for cooling and/or for heating at least one battery.

Claims

1. Battery system (1), comprising:

at least one battery (2), characterized in that it further comprises at least one Peltier element (7), which is used for cooling and/or for heating at least one battery (2).

2. Battery system (1) according to claim 1, characterized in that the Peltier element (7) is used selectively for cooling and/or for heating the battery (2) by means of switching polarity.

3. Battery system (1) according to claim 1 or 2, characterized in that the Peltier element (7) is exposed to convection.

4. Battery system (1) according to any one of the preceding claims, characterized in that the Peltier element (7) is arranged on a housing (4) of the battery (2).

5. Battery system (1) according to any one of the preceding claims, characterized in that the Peltier element (7) is arranged on a heat conducting plate (6).

6. Battery system (1) according to claim 5, characterized in that the battery (2) is formed by a plurality of cells (3), wherein a heat conducting plate (6) is arranged between at least two cells (3), which plate is guided to the outside on at least one side.

7. Battery system (1) according to claim 6, characterized in that at least two heat conducting plates (6) are included, which are also used for mechanical fixing of the cells (3).

8. Battery system (1) according to any one of the preceding claims, characterized in that at least one heat conducting plate (6) is included, which is in thermal contact with a housing (4), wherein at least one Peltier element (7) is arranged on said housing (4).

9. Battery system (1) according to any one of the preceding claims, characterized in that a control unit (8) is included, which allows the control of the temperature of the battery (2) by means of the Peltier element (7).

10. Battery system according to claim 9, characterized in that control unit (8) is arranged on housing (4).

11. Use of a battery system (1) according to any one of the preceding claims for energy storage in a motor vehicle.

12. Use of a battery system according to any one of the preceding claims as a stationary battery system.
