Abstract

A charging device for charging a motor vehicle includes an energy supply unit which is arranged externally in relation to the motor vehicle, and which is designed to provide electrical current for a solid-state gas battery of the motor vehicle. In addition, the charging device includes a gas supply unit which is arranged externally in relation to the motor vehicle and which is designed to provide gas for the solid-state gas battery of the motor vehicle. Furthermore, the charging device has at least one supply connection by which the energy supply unit can be coupled to the motor vehicle for the purposes of a charging process for supplying electrical current for the solid-state gas battery, and by which the gas supply unit can be coupled to the motor vehicle for the purposes of the charging process for supplying gas for the solid-state gas battery.

First claim

What is claimed is:

1. A charging device for charging a motor vehicle, comprising:
an energy supply unit which is arranged externally with respect to the motor vehicle and which is configured to provide electrical current for a solid-gas battery of the motor vehicle;
a gas supply unit which is arranged externally with respect to the motor vehicle and which is configured to provide gas for the solid-gas battery of the motor vehicle; and
at least one supply connection by way of which the energy supply unit is coupleable to the motor vehicle, during the course of a charging process, for supplying the electrical current for the solid-gas battery, and by way of which the gas supply unit is coupleable to the motor vehicle, during the course of the charging process, for supplying the gas for the solid-gas battery;
wherein the at least one supply connection includes an insulated electrical line for supplying the electrical current and includes a gas line for supplying the gas and wherein the insulated electrical line is surrounded by the gas line.

2. The charging device according to claim 1 , wherein
the gas supply unit comprises a compressor which is configured to compress gas for the solid-gas battery and supply said gas to the motor vehicle, said gas being provided during the course of the charging process.

3. The charging device according to claim 1 , further comprising:
a gas-receiving unit which is arranged externally with respect to the motor vehicle and which is configured to receive gas from the motor vehicle during the course of the charging process.

4. The charging device according to claim 3 , wherein
the gas-receiving unit is coupled to the gas supply unit and is configured to at least partially supply to the gas supply unit the gas that is received from the motor vehicle during the course of the charging process.

5. The charging device according to claim 2 , further comprising:
a gas-receiving unit which is arranged externally with respect to the motor vehicle and which is configured to receive gas from the motor vehicle during the course of the charging process.

6. The charging device according to claim 1 , wherein
the gas supply unit comprises a gas treatment unit.

7. The charging device according to claim 1 , further comprising:
at least one gas tank which is arranged externally with respect to the motor vehicle and which is coupled to the gas supply unit.

8. The charging device according to claim 3 , further comprising:
at least one gas tank which is arranged externally with respect to the motor vehicle and which is coupled to the gas supply unit.

9. A charging device for charging a motor vehicle, comprising:
an energy supply unit which is arranged externally with respect to the motor vehicle and which is configured to provide electrical current for a solid-gas battery of the motor vehicle;
a gas supply unit which is arranged externally with respect to the motor vehicle and which is configured to provide gas for the solid-gas battery of the motor vehicle;
at least one supply connection by way of which the energy supply unit is coupleable to the motor vehicle, during the course of a charging process, for supplying the electrical current for the solid-gas battery, and by way of which the gas supply unit is coupleable to the motor vehicle, during the course of the charging process, for supplying the gas for the solid-gas battery; and
an air-conditioning system which is designed to cool or heat the gas for the solid-gas battery of the motor vehicle before and/or during the charging process.

10. A charging device for charging a motor vehicle, comprising:
an energy supply unit which is arranged externally with respect to the motor vehicle and which is configured to provide electrical current for a solid-gas battery of the motor vehicle;
a gas supply unit which is arranged externally with respect to the motor vehicle and which is configured to provide gas for the solid-gas battery of the motor vehicle;
at least one supply connection by way of which the energy supply unit is coupleable to the motor vehicle, during the course of a charging process, for supplying the electrical current for the solid-gas battery, and by way of which the gas supply unit is coupleable to the motor vehicle, during the course of the charging process, for supplying the gas for the solid-gas battery;
a gas-receiving unit which is arranged externally with respect to the motor vehicle and which is configured to receive gas from the motor vehicle during the course of the charging process;
at least one gas tank which is arranged externally with respect to the motor vehicle and which is coupled to the gas supply unit; and
an air-conditioning system which is designed to cool or heat the gas for the solid-gas battery of the motor vehicle before and/or during the charging process.

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

12. The charging device according to claim 10 , further comprising:
a communication interface which is configured to, during the course of the charging process, exchange signals for control of the charging process between the charging device and the motor vehicle.

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

14. The charging device according to claim 1 , wherein
during the course of the charging process, gas is received from the motor vehicle via the gas line.
