Abstract

An operating device for operating a motor vehicle has at least one solid-state gas battery that is designed to provide energy for an electric motor of the motor vehicle. In addition, the operating device has at least one high-pressure tank for receiving and storing gas for the solid-state gas battery. Furthermore, the operating device has at least one charging connection via which the solid-state gas battery can be coupled for the purposes of a charging process for receiving electrical current, and via which the high-pressure tank can be coupled for the purposes of the charging process for receiving gas.

First claim

What is claimed is:

1. An operating device for operating a motor vehicle having an electric motor, comprising:
at least one solid-gas battery which is configured to provide energy for the electric motor of the motor vehicle;
at least one high-pressure tank that receives and stores gas for the solid-gas battery; and
at least one charging connection by way of which the solid-gas battery is coupleable, during the course of a charging process, so as to receive electrical current and by way of which the high-pressure tank is coupleable, during the course of the charging process, so as to receive the gas from a charging station by way of the at least one charging connection.

2. The operating device according to claim 1 , wherein
the solid-gas battery is a metal-air battery.

3. The operating device according to claim 2 , wherein
the metal-air battery is a lithium-air battery and/or a lithium-oxygen battery.

4. The operating device according to claim 1 , further comprising:
an auxiliary energy store which is configured to receive and release energy.

5. The operating device according to claim 1 , wherein
the electric motor is designed such that, during operation of the motor vehicle, during a recuperation phase, said electric motor, as a generator, converts mechanical energy into electrical energy.

6. The operating device according to claim 1 , further comprising:
a gas store which is configured to receive and release gas from the solid-gas battery.

7. The operating device according to claim 4 , further comprising:
a gas store which is configured to receive and release gas from the solid-gas battery.

8. The operating device according to claim 1 , further comprising:
a feed line which couples the high-pressure tank to the solid-gas battery; and
an air-conditioning system which is configured to at least partially control temperature of the solid-gas battery, of the high-pressure tank and/or of the feed line.

9. The operating device according to claim 7 , further comprising:
a feed line which couples the high-pressure tank to the solid-gas battery; and
an air-conditioning system which is configured to at least partially control temperature of the solid-gas battery, of the high-pressure tank and/or of the feed line.

10. The operating device according to claim 1 , further comprising:
a gas release unit which is configured to release gas during operation or during the course of the charging process of the motor vehicle.

11. The operating device according to claim 9 , further comprising:
a gas release unit which is configured to release gas during operation or during the course of the charging process of the motor vehicle.

12. The operating device according to claim 1 , further comprising:
an electrical charging unit which is arranged in the motor vehicle and which comprises a rectifier.

13. The operating device according to claim 11 , further comprising:
an electrical charging unit which is arranged in the motor vehicle and which comprises a rectifier.

14. The operating device according to claim 1 , further comprising:
a communication interface which is designed to, during the course of the charging process of the motor vehicle, exchange signals for control of the charging process between the motor vehicle and the charging station.

15. The operating device according to claim 13 , further comprising:
a communication interface which is designed to, during the course of the charging process of the motor vehicle, exchange signals for control of the charging process between the motor vehicle and the charging station.

16. The operating device according to claim 1 , further comprising:
a control unit that controls the operation and/or the charging process of the motor vehicle.

17. The operating device according to claim 15 , further comprising:
a control unit that controls the operation and/or the charging process of the motor vehicle.

18. A system for operating a motor vehicle, comprising:
an operating device according to claim 1 ; and
the charging station which has at least one supply connection for the supply of electrical current and/or gas for the solid-gas battery during the course of the charging process of the motor vehicle.
