Abstract

A vehicle ( 52 ) is provided having at least one battery ( 35 ) for supplying at least one drive of the vehicle ( 52 ) with electricity, and having at least one gas storage device ( 33 ). At least one part of the gas storage device ( 33 ) and at least one part of the battery ( 35 ) are combined in a structural unit ( 32 ) and arranged on an underbody ( 31 ) of the vehicle ( 52 ). A method for charging a battery ( 35 ) in a vehicle ( 52 ) is also provided, in which method at least one part of a battery ( 35 ) combined in a structural unit ( 32 ) with at least one part of a gas storage device ( 33 ) is supplied with electricity by a fuel cell comprised by the vehicle ( 52 ).

First claim

The invention claimed is:

1. A vehicle, comprising:
at least one battery configured to supply at least one drive of the vehicle with electricity, the at least one battery having a plurality of battery modules or battery cells;
a structural unit that includes a carrier frame that connects the structural unit to the vehicle, the carrier frame having distinct chambers;
at least one gas storage means combined with the plurality of battery modules or battery cells of the battery in the structural unit and arranged on an underbody of the vehicle, each battery module or battery cell of the battery being in a respective one of the distinct chambers of the carrier frame; and
an e-box provided in the structural unit and being configured to monitor or regulate charging and discharging processes of the battery which is configured to supply at least one drive of the vehicle with electricity.

2. The vehicle according to claim 1 wherein the shape of the structural unit is adapted to the underbody of the vehicle to have a positive transition from the structural unit to the underbody of the vehicle.

3. The vehicle according to claim 1 wherein the structural unit is exchanged by a quick-release fastener.

4. The vehicle according to claim 1 wherein the structural unit is arranged in a center tunnel of the vehicle.

5. The vehicle according to claim 4 wherein the center tunnel of the vehicle includes both the structural unit and at least one part of an exhaust system of the vehicle.

6. The vehicle according to claim 4 wherein the center tunnel of the vehicle includes both the structural unit and at least one device to transfer driving energy to a rear axle of the vehicle.

7. The vehicle according to claim 1 wherein the structural unit is arranged in a region between two axles of the vehicle.

8. The vehicle according to claim 1 wherein the gas storage means is a hydrogen storage means.

9. The vehicle according to claim 1 wherein the battery is a high-voltage battery to supply the at least one drive of the vehicle with electricity.

10. A method, comprising:
supplying at least one drive of a vehicle with electricity from at least one battery, the vehicle including a structural unit that includes a carrier frame that connects the structural unit to the vehicle, the carrier frame having chambers, the vehicle including at least one gas storage means, at least one part of the gas storage means and at least one part of the battery being combined in the structural unit and arranged on an underbody of the vehicle, and respective parts of the battery of the vehicle being in the chambers;
supplying electricity to the at least one part of the battery combined in the structural unit with the at least one part of a gas storage means by a fuel cell comprised by the vehicle; and
regulating charging or discharging of the at least one part of the battery via a control device arranged in the structural unit depending on a fill level of the at least one part of the gas storage means.

11. The method according to claim 10 , further comprising:
deactivating a high-voltage system of the vehicle, which high-voltage system is supplied with electricity by the at least one battery, by disconnecting an isolating plug at a position in an interior space of the vehicle.
