Definitions
- the invention relates to a device for switching off at least one stand-by power device.
- the invention also relates to a method for switching off such a stationary power device, particularly when used in a motor vehicle.
- a power generation system for a vehicle with an internal combustion engine in which a fuel cell system is present instead of an alternator.
- the fuel cell layer is supplied by the liquid motor vehicle fuel, from which hydrogen is split off.
- the remaining fuel components are either burned or returned to the fuel tank as liquid condensate.
- electricity consumers can operate independently of an alternator, i.e. especially when the engine is stopped. One therefore speaks of a stand-by power device.
- stand-by power devices for example in a vehicle - are stand-alone power consumers such as air conditioning, heating, a cool box, etc. and stand-by power generators such as a battery, a rechargeable battery or a fuel cell module.
- stand-by power generators such as a battery, a rechargeable battery or a fuel cell module.
- the latter stationary power generator in particular requires reaction gases or chemical reactants and, if it is in operation, therefore consumes fuel even when the vehicle is at rest.
- the device can accidentally run for a weekend, for example, and second, the tank is empty and the vehicle, for example no longer ready for operation if one or more stand-alone power devices were intended but have been in operation for too long.
- the object of the invention is therefore to provide a device and a method by which the undesirable fuel consumption by stand-by power devices is at least restricted in such a way that the devices are switched off at a predetermined minimum tank fill level.
- the invention relates to a device for switching off at least one stand-alone power device, which is connected to a measuring device for determining the tank content in such a way that the information about the tank content automatically activates the device for switching off when a predeterminable value is reached.
- the invention also relates to a method for switching off at least one stand-by power device, in which a control device is provided, by means of which at least one stand-by power device is switched off as a function of the tank content.
- the device for switching off the stationary power device has an optical, acoustic, smelling and / or other display, by means of which the operator of the vehicle, before leaving the vehicle, that is to say, possibly before the vehicle door is locked, on a running display or activated stand-by device is indicated.

- a specific value can be selected for switching off the standby devices.
- the operator is informed of the state of the stand-by power device, in particular of the fuel cell system 5.
- the fuel cell system there is at least one display in the motor vehicle 1 with which the operator of the vehicle is informed of the state of the fuel cell system before leaving the vehicle.
- This can be a signal 25 for a communication network, but also an acoustic or another suitable signal.
- the information can be passed on wirelessly to the locking system of the motor vehicle 1. It is also possible to feed the information into existing communication networks, such as the telematic system known for motor vehicles, and to call it up, for example, by mobile phone.
- the control device 20 which usually evaluates further information in addition to the information about the tank content, must be connected to a transmitter 25. The operator of the vehicle or another location can be informed about the current state via the transmitter 25.
- the stand-alone power device is a fuel cell, a fuel cell module and / or a fuel cell system.
- This can be a fuel cell or fuel cell module with or without a reformer. It is possible but not mandatory that the vehicle is an electric vehicle with a fuel cell drive.
- the fuel differs depending on the standing power device and / or vehicle, whereby in the case of hydrogen it is stored in a storage rather than in a tank, which is why the term “tank *” can also mean a storage here.
- tank * can also mean a storage here.
- tank * is not only a conventional fuel tank such as a petrol tank, but generally the container in which the fuel is stored and carried.
- tank * can also mean a hydrogen storage.
- the measuring device for determining the tank content can be the normal gasoline measuring device of the vehicle or an independent, in particular more precise measuring device.
- the device for switching off the stand-by power device can be a simple switch which interrupts the electrical and / or the fuel line.
- the standby devices consume fuel during operation.
- the operator of a vehicle is protected from the unpleasant surprise that a running stand-alone power device completely empties the tank.
- a device for switching off at least one stand-alone power device is connected to a measuring device for determining the tank content.
