Description

Energy management device for mobile rooms

The invention relates to an energy management device for managing an energy balance in a mobile space containing a fuel cell system. Under mobile space here is, for example, a land vehicle (such as passenger cars, buses, trucks, caravans, motorhomes, or trailers), an aircraft, a buoyant device (such as a ship, motorboat, sailboat, submarine, inland vessel, coastal ship, ocean-going vessel, ferry, buoy , Seaplane), a rail vehicle, a cable car cabin or any other type of vehicle understood or a mobile or semi-mobile accommodation (such as living containers, tent, shelter or toilet house) understood.

Furthermore, the invention relates to a transmission line for the transmission of fuel and for the transmission of electrical and / or optical energy. In the transmission of electrical and / or optical energy may be a transfer of electrical energy, which serves to provide an energy consumer at the other end of the transmission line with electrical energy. Additionally or alternatively, in addition to this type of energy transmission in the narrower sense, it also means such that takes place with only low power in order to transmit data, in particular control or measurement data (telemetry signals), between the ends of the transmission line. transfer.

Moreover, the invention relates to a rope for connecting a mobile space with an attachment point.

Furthermore, the invention also relates to a rope of the same kind. Each of the two ropes can be a rope, a hawser or a cable. The threads or wires of the strands of the rope may consist of a natural product, of plastic, of metal or of a mixed product.

The invention also relates to a hose coupling component consisting of a first and a second hose coupling component.

The invention also relates to a further hose coupling component of the same type. Finally, the invention relates to a method for maintaining a needs-based maintenance of an operability of a mobile space with a fuel cell system.

In the following, the invention is explained in particular using the example of mobile spaces, which are vehicles. For the other types of mobile spaces mentioned, the invention has similar advantages and corresponding considerations apply. Today's vehicles with a fuel cell system have an on-board, permanently installed in the vehicle, energy management device that ensures when switched on that a vehicle battery (mobile battery) is always charged so far that a complete commissioning of the vehicle is possible within a few minutes. In seasons with no or only little use, therefore, it happens that the fuel cell system is continuously or more often put into operation by the onboard power management device to keep the vehicle battery at a minimum state of charge. This entails fuel consumption and wear of the fuel cell devices, although there is no real vehicle use during these periods. The fuel consumption and wear occurring during non-use of the vehicle is associated with costs and environmental impact. In particular, ecologically adjusted vehicle users therefore take at the beginning of a winter break all energy consumers of the dormant vehicle out of service. However, such an approach can - especially at the beginning of a new period of use - bring considerable loss of comfort, because the vehicle battery may have almost completely discharged by the beginning of the new period of use. Then the vehicle is not ready to go immediately. The vehicle user then has to be particularly patient with the first re-commissioning - after a long break in use - until his vehicle is finally ready to start. Depending on the type of vehicle, it may even be possible to restore the ability to take off only by means of a loaded, charged auxiliary battery. It has also been thought to take the on-board power management by means of a calendar-controlled clock at a certain date back into operation, so to speak awake from a hibernation or hibernation. But even this method has disadvantages. Because even for this electrical energy is required. In addition, due to weather dependencies and flexible scheduling of the vehicle user, the first day of commissioning usually can not be determined for several months in advance. So it happens that the driving users - for example, at a particularly early beginning of the summer period - finds a vehicle that is not yet ready to start, or that the fuel cell system was idle for days before re-commissioning, although vehicle use - for example, due to bad weather - would not have been expected anyway. It also appears possible in principle to turn on and off the on-board power management of a fuel cell vehicle as with a commercially available remote-controlled auxiliary heater with a portable remote control. Here, however, the range of the remote control is usually limited so that a vehicle user who is at a remote location, such as at home or in the office or on business, the fuel cell system in the vehicle with the entrained remote control but not put into operation or turn off can. This would be possible at best via a detour, namely, if he to an on-site person - for example, a harbourmaster or a boat club member - strives to whom he leaves the transmitter and he instructs for the commissioning or decommissioning of the fuel cell system by phone or via the Internet. Finally, for the remote control of the fuel cell system, it also appears possible to replace or supplement the on-board receiver for the hand-held transmitter by a reception system with a longer range, for example by a mobile station in accordance with the GSM or UMTS standard or by a satellite reception system with a corresponding telephony interface. However, a supplement with such equipment has the disadvantage that it increases the vehicle weight and also the total cost of the vehicle.

The invention has for its object to provide an object that enables the gapless or almost complete readiness of the mobile space from the perspective of the mobile user, while avoiding unnecessary fuel consumption, increased mobile space weight or increased mobility costs.

This object is achieved with the features of the independent claims.

Advantageous embodiments of the invention are indicated in the dependent claims.

The invention is based on a generic energy management device in that the energy management device is not firmly inserted in the mobile space. - A -

is building. As a result, the mobile user can be provided with efficient power management for his mobile space, without having to incur considerable acquisition or retrofitting costs on the mobile space side. Also, the weight of the vehicle and its performance characteristics remain unchanged. For example, it is also possible to rent the energy management device according to the invention to the mobile user or to grant him a pro rata usage right in return for a user fee.

In a preferred embodiment, the energy management device is intended to be arranged at a stand or at a berth of the mobile space. At these locations, the energy management device according to the invention is particularly advantageous because mobile rooms often remain unattended for such periods at such locations for a long time. The power management device may also have a function that protects the mobile room and / or the power management device against theft.

In a further preferred embodiment, at least part of the energy management device is part of an attachment point, in particular a jib, a bollard, a cleat or another mobile space. This has the following advantages: The energy management device can be reliably - and on request even inconspicuously - attached to a pier, on a bear or on a deck, without forming an obstacle that is not already present or an additional stumbling block. In addition, connecting points or interfaces can thus be provided at the stand or berth at a common location, which serve to supply the mobile space with other services such as telemetry, communication, power supply and fuel supply. Due to the local combination of the various connection options, the stand or berth becomes clearer, safer and aesthetically pleasing due to its tidiness.

In a preferred embodiment, the power management device is provided for power management of a plurality of mobile rooms. Considering the cost of a single mobile space, it can be seen that this embodiment results in a significant cost savings in the purchase and operation of the energy management facility. In addition, an embodiment is advantageous in which the energy management device is intended to manage an energy budget of the fuel cell system, which is arranged in the mobile space. A fuel cell system usually has complex characteristics that should be considered in the operation when efficient use of the fuel cell system is desired. The energy management device can thus contribute to optimally exploiting the possibilities of the fuel cell system in the mobile space.

In a likewise preferred embodiment, the energy management device has a fuel storage and / or a rechargeable battery. An energy management device own fuel storage may serve to operate in the power management device own power generator such as a fuel cell system. In addition, the energy management device's own fuel storage can serve as a fuel replenishment source for the fuel cell system of the mobile space. With an energy management device-specific battery, it is also possible to operate the energy management device at a low-infrastructure stand or berth at which there is no power supply connection.

In a preferred embodiment, the energy management device is provided to perform the power management depending on at least one environmental parameter and / or at least one mobile space parameter. Since the energy demand of a mobile space depends on environmental parameters such as outside temperature and on mobile parameters such as heat insulation capability, inclusion of such parameters makes it possible to improve the quality of power management.

In a further preferred embodiment, the energy management device is intended to be supplied with electrical energy and / or fuel by the fuel cell system of the mobile space.

In a preferred embodiment, one of the environmental parameters includes a measured outside air temperature, a water temperature, a weather forecast date, a time parameter, and / or a calendar-specific parameter. A scenario from which the desirability of including time parameters and / or derspezifischen parameters is immediately apparent, is described in the figure description.

In a further preferred embodiment, the energy management device detects one of the environmental parameters with a sensor that has an energy management device. By means of its own tailored to the requirements of the power management own sensor, such as a wind and sun-protected outside air temperature sensor, the calculations of the power management device are placed on a reliable baseline data.

In a likewise preferred embodiment, one of the mobile space parameters comprises an internal temperature, an engine temperature, a charge state of an energy store and / or a power converted in the mobile space, in particular an electric power converted in the mobile space. To put energy management on a reliable basis for calculation and decision-making, it is very advantageous from the point of view of the energy management device if the thermal and electrical actual state of the mobile space to be managed is known. Therefore, it is appropriate to detect one or more of these mobile space parameters.

In a further preferred embodiment, a radio connection or a cable connection is provided to transmit an environmental parameter and / or a mobile space parameter to the energy management device.

In a particularly preferred embodiment, a radio link or a cable connection is provided to transmit a control signal from the power management device via a radio link or via a cable connection to the mobile space. In both of the aforementioned embodiments, the variant with the radio link offers the advantage that energy management is possible even with a power management device (for example in a boathouse or at a pier), even if the mobile space rests in a place that is not directly accessible (for example, because it anchored in the outer area of a harbor).

The invention is based on a generic transmission line in that the fuel and signal transmission line comprises a fuel hose and a signal transmission cable, wherein the signal transmission cable is mechanically connected to the fuel hose over a predominant length of the fuel hose. that is. This makes it possible to reduce the number of connecting elements between the mobile space and energy management device to a minimum, whereby clarity, security and aesthetics of the stand or berth is improved.

The invention builds on a generic rope for securing a mobile space at an attachment point characterized in that at least one strand of the rope comprises a fuel hose helically. The helically encompassing strand has a protective function for the fuel hose against damage to the hose jacket.

In a further aspect, the invention builds on a generic rope for securing a mobile space at an attachment point in that a fuel hose comprises at least one strand of the rope helically. The two above-mentioned types of ropes according to the invention have an improved rigidity compared to conventional fuel hoses, which is why loops and kinks are less easily formed and a risk of injury to persons and objects is reduced.

The invention is based on a generic hose coupling component for a hose coupling characterized in that when a predetermined tensile force on the hose coupling is exceeded, first the fuel valve is automatically closed and then the locking member releases the hose coupling automatically. Since the fuel hose is usually used to guide a fuel that should not get into free waters for environmental compatibility reasons, a hose coupling technology is required, which - even with clumsy handling by laymen - prevents accidental spillage of fuel.

The invention is based on a generic hose coupling component for a hose coupling, characterized in that the hose coupling component comprises both connecting elements for transmitting a fuel and connecting elements for transmitting optical and / or electrical energy. This makes it possible in a comfortable way, both types of connection in a single operation and at the same time to produce. This also prevents that only one of the two types of connection is made if the user is interrupted during this work. The invention is based on the generic method for maintaining the serviceability of a mobile space on demand, in that the method comprises the following steps: acquisition of data; Determining a weather forecast; Determining a prediction of use of the mobile space; Calculating a planned course of operation of the fuel cell system over one or more temporal scheduling sections from the course of weather predicted in the second step and from the course of the mobile space usage predicted in the third step; Checking whether a time difference between a start time of the one time planning section and the current time is below a threshold value for one of the time planning sections of the planned course of operation of the fuel cell system determined in the fourth step; and if so, performing an operation of the fuel cell system according to this one of the scheduling sections. With this method according to the invention, it is possible to produce a complete or almost complete operational readiness of the mobile space, while at the same time avoiding unnecessary fuel consumption, increased mobile weight or increased mobile space costs.

The invention will now be described by way of example with reference to the accompanying drawings by way of particularly preferred embodiments.

In the following, features of the arrangements shown in the figures will be described, which may be realized in a common embodiment.

FIG. 1 shows a perspective sketch with a boat 10, in whose fuselage a fuel cell system 12 is arranged. The boat 10 is moored to a pier 14 by means of a rope 16 on a bollard 18 by means of a catwalk or otherwise. In the operating state shown, a fuel line 29 and a signal line 31 of the cable 16 are connected to a part of the power management device 28 located in the bollard 18. The portion of the power management device 28 located in the bollard 18 may be operated from a remote cell phone 20. For this purpose, the part of the energy management device 28, which is located in the bollard 18, includes its own mobile station 62 which can exchange data with the mobile phone 20 via a mobile radio network 22 with base stations 24, 26. Preferably, the entire power management device 28 is housed in a cavity of a particular bollard 18 or boom or barge. The bollard housing may for example consist essentially of metal or of a fiber-reinforced plastic and may also be constructed of a multilayer material, for example a vulcanized perforated or slotted aluminum tube. The bollard 18 has on the top an opening from which a fuel hose 29 with attached data cable 31 is pulled out with a data connector and can also be returned. The rope 16 has the following three functions. On the one hand, it serves the usual mooring of the ship 10 by means of a prepared loop or by means of a node 35 on the special bollard 18. It also serves from a fuel tank 37 in the bollard 18, in the boom or in the beard on a liquid and gas-tight Flange connection 59 fuel 42 to the ship 10 to pass. The third function is to provide a transmission medium for data exchange between the ship 10 and the bollard 18. Preferably, the flange connection 59 has an integrated electrical contact device. The data cable 31 embedded in the cable 16 may be a fiber optic cable for transmitting optical data signals or an electrical cable such as an ethernet cable. An alternative or additional deposit of a power supply cable, not shown, is possible. Furthermore, one or more fuel pumps and / or (check) valves can be integrated into the cable. Thus, fuel (and other liquids as well) can be transported in a particularly reliable manner in sections to a higher location, for example, up to a ship deck higher than the pier or in the carrying cable of a cable car up to a mountain station. For this purpose, the integrated fuel pumps can be supplied with electrical energy by a power cable embedded in the cable. A hose can also be provided in the cable which is used in the reverse direction of flow, for example for driving the integrated pumps for the upward direction or for returning liquids from the ship deck or from the top station. It is also possible to provide a cable 16 as described above, but without a data cable 31 or a cable 16 as described above, but without a fuel hose 29.

In order to minimize the risk of leakage of fuel 42 by tearing off the fuel hose 29, both coupling components 56, 58 are each attached to a movable part 50, 51. The power management device side coupling component 56 is the termination part at the loose end 54 of the power management device side movable part 50, while the mobile side coupling component 58 is the termination part at the loose end of the mobile side moving part 51. Now, if pulled from the mobile space side or power management side of the hose 29, then the main axis of the clutch 59 is oriented axially in the direction of traction due to the loose ends on both sides. When exceeding a predetermined tensile force on the hose coupling 59 closes - due to a force measuring mechanism - in the clutch 59 automatically a fuel valve disposed in the power-management device side coupling component 56, and only thereafter a locking part automatically releases the mechanical connection of the hose coupling 59 due to the force measuring mechanism.

In principle, it is possible to arrange a coupling component 56 or 58 on both sides of the cable 16. Depending on the configuration chosen, complementary coupling components 56, 58 are to be arranged on the power management device 28, on the mobile space 10, or on both. When one side of the cable 16 is fixedly secured to the power management device 28 or to the mobile space 10, a cable drum for rolling up and stowing the cable 16 may be provided at this location.

2 shows a block diagram of an arrangement with the vessel 10 and the energy management device 28 according to the invention. The vessel 10 comprises an internal combustion engine 30, the fuel cell system 12, a fuel tank 32, a rechargeable mobile battery 34 and a battery charge controller 36. The battery charge controller 36 monitors by means of a Battery charge sensor 38 a state of charge of the mobile battery 34. The battery charge controller 36 includes a two-step controller, not shown. As soon as the amount of energy stored in the mobility chamber 34, which is referred to as charge, falls below a lower threshold value set in the battery charge controller 36, it switches on the fuel cell system 12 via an electrical control line 40. The fuel cell system 12 then removes fuel 42 from the fuel tank 32 and generates electrical energy by means of the chemical energy contained in the fuel 42. An electrical charging line pair 44, 46 together with the fuel cell system 12 and the mobile battery 34 forms a circuit. The electrical charging line pair 44, 46 supplies the mobile battery 34 with electrical energy generated by the fuel cell system 12, wherein the mobile battery 34 is charged with electrical energy. In this case, the battery charge controller 36 continues to monitor the state of charge of the mobile battery 34 by means of the sensor 38. As soon as the amount of energy stored in the mobile battery 34 exceeds an upper threshold set in the battery charge controller 36, it shuts off the fuel cell system 12 via the electric control line 40.

The power management device 28 includes a power management controller 48 and an interface cable 50 that has a first end 52 that is connected to the power management device 28 is mechanically fastened, and has a loose second end 54. The first end 52 is electrically connected to the power management controller 48. At the loose end 54, the interface cable 50 has an energy management device-side coupling component 56. The battery charge controller 36 includes a complementary mover-side clutch component 58 mating with the power manager-side clutch component 56. Preferably, the mover-side clutch component 58 is mechanically fixed to the battery charge controller 36 or other portion of the vehicle compartment 10.

The power management device 28 serves to influence the battery charge controller 36 so that, when using the mobile space 10, the mobile battery 34 is sufficiently charged, and otherwise unnecessary charging is avoided to avoid unnecessary fuel consumption becomes.

Depending on the embodiment, the energy management device 28 has to various interfaces 62 and sensors 60, via which it receives data from which it uses a computing means, not shown in the power management controller 48 derives a decision in which of at least two operating conditions, the fuel cell system 12 with which power currently in operation, so that the mobile battery 34 is charged further or not. Typically, the computing means comprises a program on a computer.

The procedure is preferably as follows:

In a first method step, measured values and data are acquired by the various sensors 60, 62. Here, the word sensor is also understood in a broad sense. This also means, for example, access to a website containing data useful for the present task. Such an internet site may, for example, contain weather forecast data.

Also, permanently programmed or manually entered prognostic data about a user behavior of the mobile user can be stored in a non-volatile memory of the computer. In a simple case, these usage forecast data contain only a start and an end date of a rest period, for example that's a winter break. However, more flexible embodiments are also possible, in which a mobile user can enter specific time of use in a calendar provided for this purpose to the exact time or even by the hour or quarter of an hour. For example, such a calendar can be provided on a dedicated website. A connection to an interface of one of the standard PC, organizer, PDA programs or mobile phone functions for appointment organization, such as MS-Outlook, is conceivable. In particular, an individual usage behavior of a plurality of mobile users of a mobile space 10 can be detected via the means mentioned for the energy management device 28. If multiple mobile rooms 10 are shared by multiple mobile users, the association between mobile 10 and mobile user is not one-to-one but flexible. From a data model point of view, this is then similar to the situation in which several people share a common meeting room and this is recorded in a scheduling program in order to avoid temporal overlaps. If, for example, in a vehicle fleet or in a boat club, such occupancy planning is already provided anyway for organizational reasons, these data can be used in an ideal manner as usage prediction data for the energy management device 28.

As a further sensors, in particular a radio clock for the detection of date and time, an outside temperature sensor 60, an anemometer and a humidity meter come into consideration.

These sensors 60, 62, 64 may be mounted both at the location of the power management device 28 and on the mobile space 10. Measurements from the sensors 60, 62, 64 for the current in the mobile space 10 converted electrical power, for the filling state of the fuel cell fuel tank 32, for a temperature of the internal combustion engine 30 and the fuel cell system 12, the power management controller 48 via the battery charge controller 48 and line 50 or directly via Line 50 received.

In a second method step, the computing means derive a prediction of the course of the weather.

In a third method step, the computing means derives a prediction of the course of the use of the mobile space. Preferably, not only are groove but also a course of a time-dependent degree of utilization and / or a course of a time-dependent probability of use predicts. The likelihood of mobile space usage typically depends on the nature of the day of the week as well as the weather. For recreational vehicles of professionals is a holiday on public holidays and weekends with nice weather much higher than other days. In contrast, for purely business-used mobile spaces, the use is rather weather-independent and on public holidays and weekends unlikely. For energy management, it would therefore be advantageous if the mobile user had a possibility with which he - such as on a website of the discussed Internet service - could enter such an indication of his consumption behavior.

In a fourth method step, a planned course of the operation of the fuel cell system for one or more time planning sections is calculated from the course of the weather forecast in the second step and from the course of mobile space utilization predicted in the third step. In the degenerate case, the planned course consists of only a single planning section. A time planning section contains, for example, a specification that the fuel cell system is operated in a specific operating mode in an assigned period, for example on a specific calendar day, for example at half maximum power. However, a single planning section may itself also comprise a fixed predetermined or parameterizable "run" over a plurality of operating modes, for example for starting up or shutting down the fuel cell system A particularly preferred embodiment provides that an optimization program is carried out in terms of mobile space availability, fuel consumption In particular, specific properties of the fuel cell system 12, such as dependence of the efficiency of the fuel cell system 12 and low efficiency of the fuel cell system 12 in the start-up phase compared to a real operation in steady state The energy requirement for the optionally required preheating of the internal combustion engine 30, the Brenn material cell system 12 and / or the fuel cell fuel 42 are taken into account. The power management device 28 preferably takes into account only those consumers 30 in the mobile space 10 that receive energy-in particular electrical energy-from the fuel cell system 12. Preferably, relationships that affect a lifetime of the mobile battery 34 and / or the fuel cell system 12 are also considered. For example, with batteries of certain battery technologies, a frequency of the discharge or a one-time deep discharge is decisive for the life of the battery. It would ultimately not make sense in terms of comfort, ecology and economy, in order to save fuel battery damage in purchasing, which are avoidable without loss of comfort.

Typically, several iteration steps are taken in the execution of the optimizer. In each iteration step, a weighting factor is calculated which represents a measure of a quality of the compromise determined in the iteration step. The iteration is aborted as soon as a difference of the weighting factors of two consecutive iteration steps lies below a predetermined threshold value.

In a fifth method step, it is checked whether a time difference between a start time of the one of the time planning sections and the current time is below a threshold value for one of the time planning sections of the planned course of operation of the fuel cell system determined in the fourth step.

If this is the case, this time planning section of the planned course of the operation of the fuel cell system is carried out in a sixth method step. For this purpose, the energy management device 28 transmits a control signal via a control line 66 to the battery charge controller 36. Thus, an adaptation of the operating state of the fuel cell system 12 to the planned course of the operation of the fuel cell system is caused.

In a seventh method step, the power management device 28 calculates a new time when it can be woken up again from a sleep mode by an internal clock. Typically, the power management device 28 may be woken up once a day or once an hour. The power management device 28 sets the wake-up time and enters the sleep mode. The sleep mode is characterized in that in this case only absolutely necessary consumers of the energy management device 28 are switched on, for example, to the energy manager. wake up wake-up time from the sleep mode or to respond to an incoming via a communication interface control signal, if desired.

For example, the power management device 28 may include a transceiver 62, such as a mobile station, configured to receive and supply some or all of the previously discussed sensor data to the power management controller 48. For such telemetry-related tasks devices like the M20 from Siemens are suitable. Alternatively or additionally, the transmitter receiver 62 can also be provided to receive further control or configuration commands for the energy management controller 48 or for the battery charge controller 36 and to supply it to the energy management controller 48. In addition, the transceiver 62 may also be configured to report maintenance and diagnostic data of the fuel cell system 12, the battery charge controller 36, and / or the power management device 28, or environmental measurements, such as temperature readings, to a central display and / or evaluation device. The central evaluation device is in the simplest case, the mobile phone 20 of the mobile user, on the display 68 a short message (SMS), such as a message is displayed that a fuel tank 32 is to be refilled. For example, it would also be possible to integrate an anti-theft function in the arrangement described above, so that a message is sent to the mobile user via the transceiver 62 as soon as the anti-theft alarm triggers a silent or a loud alarm. If only a small distance between the mobile space 10 and the power management device 28 is to be bridged, then a Bluetooth or WLAN connection may be sufficient for this. For example, could be housed in a bollard 18 or in a boathouse a wireless router. In all variants with radio connection, care must be taken that the antenna 70 of the radio station 62 is arranged at a suitable radio location.

Another scenario is shown in FIG. In this case, the transceiver 62 is normally not used directly by the mobile user, but by means of a central Internet service 72, which is preferably arranged at the manufacturer of the fuel cell system 12 or at the energy management device 28. The Internet service 72 runs on a server 76 connected to the Internet 74. The mobile user can carry out all important control and interrogation functions for him, by logging into the Internet service 72 on the server 76 by means of a personal computer 78 or a mobile phone 20. Such an arrangement has the advantage that the operator of the Internet service 72 can filter and process all data in such a way that operating errors and misinterpretations by the mobile users are largely precluded. In addition, the Internet service provider may collect and consolidate the data from a plurality of geographically different positioned power management devices 28 to compute a weather history tailored for the Internet service 72. In addition, the Internet service provider can advantageously establish overarching operating strategies for the temporal and / or quantitative distribution of the available resources. For example, it may control battery charge controllers 36 of a plurality of mobile rooms 10 such that only a total of fuel 42 is taken from a plurality of mobile rooms 10 that receive fuel 42 from a common fuel source such that the common fuel source capacity is not exceeded. With a time sharing method it can be achieved that all mobiles 10 are supplied with fuel, but not all at the same time, so that during the supply of a single mobile space 10 a predetermined minimum flow rate of fuel per unit time is maintained, which may be more advantageous for fuel-hydraulic reasons to serve all mobile spaces 10 simultaneously with a lower flow rate of fuel per unit time. It can also be used to promote economic optimization of fuel distribution logistics. Based on the messages from the power management device 28, the Internet service 72 can detect when which stall 14 is to be supplied with fresh fuel or refilled fuel return containers. If, for example for organizational reasons, it is not possible to approach a stationary or lying area 14 quickly with new fuel, the Internet service 72 can, if necessary, throttle the fuel consumption of the fuel cell even further than the calculation results of the fourth method step dictate. The throttling of the fuel consumption can take place by changing the consumption behavior of the fuel cell systems 12 in the managed mobile spaces 10. Preferably, the functional partitioning in this scenario is as follows: The on-vehicle systems include all the functions required for autonomous operation of the fuel cell system 12. A part of the energy management device which is not permanently installed in the mobile space and contains all functions which, like the outdoor temperature transmitter 60, are needed for power management according to the inventive method in the vicinity of the mobile space, but not for self-sufficient operation of the fuel cell system 12. Apart from the communication functions required for the entire arrangement in all places, a non-mobile-related part (Internet service on Internet server) of the non-mobile-mounted power management device contains all other functions of the power management device according to the method of the present invention.

FIG. 4 outlines a cross section 80 shown in perspective and a side view 82, shown in perspective, of a partially cut-open cable 16 according to the invention, which preferably has at least one seale-type strand. In this case, the fuel hose 29, together with parallel-guided strands 84, surrounds an inner strand of the cable 16 in a helical manner. The structure thus formed constitutes an inner carding 86. The inner carding 86 in turn is helically surrounded by an outer layer of strands 88. This therefore also applies to the fuel hose 29. In a preferred embodiment, all strands 84, 88 are wound in the same direction. In order to prevent squeezing of the fuel hose 29, this can be equipped at regular intervals with a spacer 90, in particular with a metal or plastic ring 90. As shown in Figure 4, but it is independently possible to make the outer layer of strands 88 in a direction opposite to the inner layer of strands 84 impact direction. In this construction, a cage-like structure results, whereby the outer layer of strands 88 is more strongly supported on the inner strands 84, since they are less compliant than the fuel hose 29. A similar effect can also be achieved in that the outer strands layer 88 with another Lay length is executed as the outer. Some rope constructions have in cross-section considerable gaps 92, which are preferably filled with plastic by, for example, applied to the circumference of the inner Kardeel 86 a tubular plastic intermediate layer or is raised. As a result of the fact that metal surfaces of the strand layers 84, 88 can no longer touch directly and can no longer be damaged by direct chafing of metal against metal, the durability of the cable 16 can be improved. In order to prevent damage to the fuel hose 29 by such processes, the fuel hose 29, which consists of a plastic suitable for fuel, be sheathed with a hose or grid-like protective sheath, not shown, of another plastic, which has better mechanical properties for this purpose. Some cable constructions have in cross-section 80 very large filled with plastic spaces 92. It seems quite possible to enter one or more such spaces 92 instead of the art stoffs each embed a cable 31 or a fuel hose 29. With a suitable design can also be thought of to arrange the fuel hose 29 as a central core 94 and him helically with one or two layers of strands 84, 88 to wrap. The entire cable construction can be covered with a protective cover 98 or a protective braid 98, which then also forms part of the cable 16.

FIG. 5 shows a perspective sketch of a ship 10 that lies far away from a pier 14 in front of anchor 96 and in which a portable power management device 28 can be operated from a remote mobile phone 20. In this case, the energy management device 28 is arranged in a suitcase or handheld device which the mobile user obtains, for example, from a harbor master, parking garage management, fleet management, airport management or campsite management and then set up in his mobile space 10, in a boathouse or at another location.

In principle, it is also possible to realize almost all parts of the power management device 28 as a software program for a personal computer (PC) 78 or for a mobile phone 20 or for a personal digital assistant (PDA) 78 or as part of an internet service 72 in which the mobile user can log in with a standard browser and password. For the communication / data connection between the battery charge controller 36 on the mobile space 10 and a power management device 28 on the PC, the PDA or the Internet server 76, a commercially available communication component such as a mobile station 62 and message networks 22, 74 may be used, to which the mobile station used 62 provides access. In the extreme case, a mobile station 62 on the mobile space 10 is even able to directly interrogate the charge state from the battery charge sensor 38 and report it to the power management device 28 and directly control the operation of the fuel cell system 12 in accordance with instructions from the power management device 28. In such an arrangement, the power management device 28 would take over the tasks of the battery charge controller 36. This embodiment is particularly suitable if all components on the mobile space side are to remain permanently on the mobile space 10, since in this case the equipment and cost on the mobile space side and the equipment weight on the mobile space side are the smallest. Preferably, the fuel cell system 12 and / or the electrical system 36 in the mobile space 10 are designed such that they can always be operated without the energy management device 28 according to the invention, at least if necessary.

The features of the invention disclosed in the foregoing description, in the drawings and in the claims may be essential to the realization of the invention both individually and in any combination.
