Abstract
A mobile emergency charging device for a battery of a motor vehicle that is designed to charge the battery in a recuperation operation. The mobile emergency charging device has at least one fuel tank, an internal combustion engine, and at least one drive roller for driving a wheel of the motor vehicle. This at least one drive roller is connected at least indirectly to an output shaft of the internal combustion engine and, by way of this connection, the drive roller is set into a rotational movement when the internal combustion engine is running.
Claims10
A mobile emergency charging device for a battery of a motor vehicle that is designed to charge the battery in a recuperation operation, comprising:
- at least one fuel tank, an internal combustion engine, and at least one drive roller for driving a wheel of the motor vehicle;
- the at least one drive roller is connected at least indirectly to an output shaft of the internal combustion engine and is set into a rotational movement by way of this connection when the internal combustion engine is running;
- the drive roller can be positioned beneath one of the wheels of the motor vehicle in such a way that, by the rotating drive roller, when the internal combustion engine of the mobile emergency charging device is running, the wheel in question is set into a rotational movement, and the battery is thereby charged in the recuperation operation of the motor vehicle.
A motor vehicle having a battery, which is designed for the purpose of charging the battery in a recuperation operation,
- wherein the motor vehicle has a lifting mechanism, which is designed to increase the distance between at least one wheel of the motor vehicle and an undersurface far enough that a mobile emergency charging device can be positioned between the at least one wheel and the undersurface,
- wherein the mobile emergency charging device comprises at least one fuel tank, an internal combustion engine, and at least one drive roller for driving the at least one wheel of the motor vehicle,
- wherein the at least one drive roller is connected at least indirectly to an output shaft of the internal combustion engine and is set into a rotational movement by way of this connection when the internal combustion engine is running,
- wherein, when the mobile emergency charging device is positioned between the at least one wheel and the undersurface and when the internal combustion engine of the mobile emergency charging device is running, the wheel in question is set into a rotational movement by the rotational movement of the drive roller, and the battery is thereby charged in the recuperation operation of the motor vehicle.
