Description

The The invention relates to a power management device for management an energy balance in a mobile space that is a fuel cell system contains. Under mobile space here is for example a land vehicle (such as passenger cars, bus, Lorry, caravan, camper or trailer), an aircraft, a buoyant device (such as ship, motorboat, sailboat, submarine, barge, coastal ship, Ocean-going vessel, ferry, Buoy, seaplane), a rail vehicle, a cable car cabin or another type of vehicle understood or a mobile or semi-mobile accommodation (such as living container, tent, shelter or Outhouse) Understood.

Farther The invention relates to a transmission line for transmission of fuel and for transmission of electrical and / or optical energy. In the transmission The electrical and / or optical energy may be a transmission of act electrical energy that serves an energy consumer at the other end of the transmission line to supply with electrical energy. Additionally or alternatively here next to this kind of energy transfer in the narrower sense also understood as one that takes place with only low power, around between the ends of the transmission line Data, in particular control or measurement data (telemetry signals) transferred to.

It also concerns the invention a rope for connecting a mobile space with a Attachment point.

Of Furthermore, the invention relates to a rope of the same genus. Each of the two ropes can be a rope, a hawser or a cable be. The threads or wires the strands of the rope can from a natural product, plastic, metal or one Consist of mixed product.

The The invention also relates to a hose coupling component comprising a first and a second hose coupling component consists.

Also The invention relates to a further hose coupling component of the same genus.

Finally, concerns the invention a method for maintaining a needs-based Maintenance of operability 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 fuel cell system have an on-board, built-in power management device in the vehicle, which ensures that a vehicle battery (mobile battery) is charged whenever possible so far that a complete commissioning of the vehicle is possible within a few minutes. In seasons with little or no use at all, 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 significant loss of comfort, because the vehicle battery may have discharged almost completely until 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 then that the vehicle users - for example, at a particularly early beginning of the summer - finds a not yet startklares vehicle, or that the fuel cell system was useless for days before re-commissioning in operation, although a 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 on a remote location, for example, at home or in the office or on business trip, is the fuel cell system in the vehicle with the entrained remote control but not in operation or off. 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, it appears to remote control of the fuel cell system also possible to replace or supplement the on-board receiver for the remote control by a reception system with a longer range - for example, by a mobile station according to GSM or UMTS standard or by a satellite reception system with appropriate telemetry interface. However, a supplement with such equipment has the disadvantage that it increases the vehicle weight and also the total cost of the vehicle.

Of the Invention has for its object to provide an article from the perspective of the mobile user a gapless or almost complete Readiness of the mobile space allows, and at the same time Avoiding an unnecessary Fuel consumption, an increased Vehicle weight or increased Container transport costs.

in the Following are features of the arrangements shown in the figures described, which are realized in a common embodiment can.

1 shows a perspective sketch with a boat 10 in whose hull a fuel cell system 12 is arranged. The boat 10 is at a pier 14 by means of a rope 16 on a bollard 18 moored by a catwalk or otherwise. In the operating state shown are a fuel line 29 and a signal line 31 of the rope 16 to a part of the power management device 28 who is in the bollard 18 is connected. The part of the power management device 28 who is in the bollard 18 can be located from a remote phone 20 be served from. This includes the part of the power management device 28 who is in the bollard 18 is a separate mobile station 62 the one with the mobile 20 Data over a mobile network 22 with base stations 24 . 26 can exchange. Preferably, the entire power management device is 28 in a cavity of a special bollard 18 or jib or one Barge accommodated. 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 data cable attached 31 pulled out with a data connector and can also be returned. The rope 16 has the following three functions. First, it serves the usual mooring of the ship 10 by means of a prepared loop or by means of a knot 35 on the special bollard 18 , It also serves to get out of a fuel tank 37 in the bollard 18 , in the boom or in the barge via a liquid and gas-tight flange connection 59 fuel 42 to the ship 10 to lead. 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 an integrated electrical contact device. That in the rope 16 embedded data cables 31 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 may also be provided in the cable which is used in the reverse flow direction, for example for driving the integrated pumps for the upward direction or for the return of liquids from the ship deck or from the top station. It is also possible to use a rope as described above 16 but without data cable 31 or a rope as described above 16 but without fuel hose 29 provided.

To the risk of leakage of fuel 42 by tearing off the fuel hose 29 to minimize, are both coupling components 56 . 58 each on a moving part 50 . 51 appropriate. The power management device side coupling component 56 is the final part at the loose end 54 of the power-management device-side moving part 50 while the mobile space side hitch be component 58 the termination part at the loose end of the mobile-space-side movable part 51 is. If now from the mobile site or power management side on the hose 29 is pulled, then the main axis of the coupling depends on the two ends loose ends 59 axially in the direction of the tensile force. When a predetermined tensile force on the hose coupling is exceeded 59 closes - due to a force measuring mechanism - in the clutch 59 automatically a fuel valve in the power management device side coupling component 56 is arranged, and only then releases a locking member due to the force measuring mechanism automatically the mechanical connection of the hose coupling 59 ,

Basically it is possible on both sides of the rope 16 a coupling component 56 or 58 to arrange. Depending on the selected configuration are complementary coupling components 56 . 58 at the power management device 28 , on the mobile space 10 or to order both. If one side of the rope 16 at the power management device 28 or on the mobile space 10 firmly attached, in this place can be a rope drum for rolling up and stowing the rope 16 be provided.

2 shows a block diagram of an arrangement with the vessel 10 and the power management device according to the invention 28 , The watercraft 10 includes 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 control 36 monitored by means of a Batte rieladungssensors 38 a state of charge of the mobile battery 34 , The battery charge control 36 includes a two-step controller, not shown. Once in the mobile battery 34 stored amount of energy, which is referred to as charge, one in the battery charge control 36 set lower threshold, it switches over an electrical control line 40 the fuel cell system 12 one. The fuel cell system 12 then takes the fuel tank 32 fuel 42 and generated by means of in the fuel 42 contained chemical energy electrical energy. An electrical charging line pair 44 . 46 forms together with the fuel cell system 12 and the mobile battery 34 a circuit. The electrical charging line pair 44 . 46 leads the mobile battery 34 from the fuel cell system 12 generated electrical energy, wherein the mobile battery 34 is charged with electrical energy. Thereby monitoring the battery charge control 36 the state of charge of the mobile battery 34 continue by means of the sensor 38 , Once in the mobile battery 34 stored energy amount in the battery charge control 36 exceeds the set upper threshold, it switches over the electrical control line 40 the fuel cell system 12 out again.

The power management device 28 includes an energy management control 48 and an interface cable 50 that's a first end 52 at the power management device 28 mechanically fastened, as well as a loose second end 54 having. The first end 52 is with the power management control 48 electrically connected. At the loose end 54 has the interface cable 50 a power management device side coupling component 56 on. The battery charge control 36 includes a to the power management device side coupling component 56 matching complementary mobile space-side coupling component 58 , Preferably, the mobile-space side coupling component 58 with the battery charge control 36 or another part of the mobile space 10 mechanically firmly connected.

The power management device 28 serves to charge the battery 36 to influence so that - if with a use of the mobile space 10 is to be expected - the mobile battery 34 is sufficiently charged, and on the other hand otherwise unnecessary charging is avoided, so that unnecessary fuel consumption is avoided.

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

The procedure is preferably as follows:
In a first step of the various sensors 60 . 62 Measured values and data recorded. 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 forecast data about a user behavior of the mobile user can be stored in a nonvolatile memory of the computer. In a simple case, these usage prediction data contain only a start and an end date of a rest period, such as 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, via the means mentioned for the power management device 28 an individual usage behavior of several mobile users of a mobile space 10 be recorded. If there are multiple mobile rooms by multiple mobile users 10 shared, is the association between mobile space 10 and mobile users are 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 ideally be used as usage prognosis data for the energy management device 28 be used.

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.

These sensors 60 . 62 . 64 can both at the location of the power management device 28 , as well as on the mobile space 10 be attached. Measured values 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 can the power management control 48 via the battery charge control 48 and direction 50 or directly via wire 50 receive.

In In a second method step, the computing means make a prediction about the Derived from 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 periods of use are forecast but also a course of a time-dependent degree of utilization and / or a course of a time-dependent probability of use. 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, is purely business mobile use is rather weather-independent and unlikely on holidays and weekends. 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 the use of the mobile space predicted in the third step. In the degenerate case, the planned course consists of only a single planning section. By way of example, a time planning section contains 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 include a fixed predetermined or parameterizable "sub" course 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 during the calculation, which determines a well-acceptable compromise for the course of the operation of the fuel cell system with regard to mobile space availability, fuel consumption and environmental compatibility. In particular, specific properties of the fuel cell system can be used 12 how dependence of the efficiency of the utilization of the fuel cell system 12 and low efficiency of the fuel cell system 12 in the start-up phase compared to an active operation in the steady state, are taken into account. Also, the energy requirement for possibly required preheating the internal combustion engine 30 , the fuel cell system 12 and / or the fuel cell fuel 42 be taken into account. Preferably, the energy management device 28 only such consumers 30 in the mobile space 10 takes into account the energy - especially electrical energy - from the fuel cell system 12 Respectively.

Preferably, also relationships are taken into account, which is a lifetime of the mobile battery 34 and / or the fuel cell system 12 affect. For example, with batteries 34 certain battery technologies, a frequency of discharge or a single deep discharge for the life of the battery is crucial. 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, be in the lead of the optimizer go through several iteration steps. In each iteration step, a weighting factor is calculated, a measure of goodness in the Iteration step determined compromise represents. The iteration is aborted as soon as a difference of the weighting factors of two successive Iteration steps below a predetermined threshold lies.

In a fifth Step is checked for a the temporal planning stages of the determined in the fourth step planned course of operation of the fuel cell system a Time difference between a start time of one of the temporal Planning sections and the current time below a threshold lies.

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. To do this transmits the power management device 28 a control signal via a control line 66 to the battery charge controller 36 , Thus, an adjustment of the operating state of the fuel cell system 12 to the planned course of operation of the fuel cell system.

In a seventh method step, the power management device calculates 28 a new time when she awakens from an internal clock again from a sleep mode. Typically, the power management device can be used 28 Awake once a day or once an hour. The power management device 28 sets the alarm time and goes into sleep mode. The sleep mode is characterized in that in this case only absolutely necessary consumers of the power management device 28 are turned on, for example, to wake up the power management to alarm 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 a transceiver 62 , such as a mobile station intended to receive some or all of the previously discussed sensor data and the power management controller 48 supply. For such telemetry-related tasks devices like the M20 from Siemens are suitable. Alternatively or additionally, the transceiver may 62 also be provided to further control or configuration commands for the power management control 48 or for battery charging control 36 to be received and power management control 48 supply. In addition, the transceiver can 62 also be provided, maintenance and diagnostic data of the fuel cell system 12 , the battery charge control 36 and / or the power management device 28 or report ambient readings, such as temperature readings, to a central display and / or evaluation device. The central evaluation device is the cell phone in the simplest case 20 of the mobile user, on its display 68 a Short Message (SMS), such as a message that indicates a fuel tank 32 is to be refilled. For example, it would also be possible to integrate an anti-theft function into the arrangement described above, so that via the transceiver 62 a message is sent to the mobile user 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 to be bridged, then a Bluetooth or WLAN connection can be sufficient for this purpose. For example, in a bollard 18 or in a boathouse a wireless router can be accommodated. In all versions with radio connection, make sure that the antenna 70 the radio station 62 is placed at a radio technically suitable location.

Another scenario is in 3 shown. Here, the transceiver becomes 62 normally not directly used by the mobile user, but by means of a central Internet service 72 , preferably at the manufacturer of the fuel cell system 12 or at the power management device 28 is arranged. The internet service 72 runs on one on the internet 74 connected server 76 , The mobile user can carry out all important control and interrogation functions for him by using a personal computer 78 or a cellphone 20 in the internet service 72 on the server 76 logs. Such an arrangement has the advantage that the operator of the Internet service 72 All data can be filtered and processed in such a way that operating errors and misinterpretations by mobile users are largely excluded. In addition, the Internet service operator may retrieve the data from a variety of geographically different power management devices 28 collect and consolidate and so on for the internet service 72 calculate the weather forecast. In addition, the Internet service provider can advantageously establish overarching operating strategies for the temporal and / or quantitative distribution of available resources. For example, he can battery charging controls 36 of several mobile rooms 10 so control that of multiple mobile spaces 10 that fuel 42 from a common fuel source, a total of only so much fuel 42 is taken that the performance of the common fuel source is not exceeded. With a time sharing procedure can be achieved that all mobile rooms 10 be fueled, but not all at the same time, so while supplying 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 than all mobile spaces 10 to operate 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 can the internet service 72 recognize when which stand or berth 14 with fresh fuel or refilled fuel return containers. If a stall or mooring 14 - For example, for organizational reasons - can not be approached quickly enough with new fuel, the Internet service 72 if necessary, further restrict the fuel consumption of the fuel cells than the calculation results of the fourth method step dictate. The throttling of the fuel consumption can be achieved by changing the consumption behavior of the fuel cell systems 12 in the supervised mobile rooms 10 respectively. Preferably, the functional partitioning in this scenario is as follows: The mobile space-specific systems include all functions necessary for a self-sufficient operation of the fuel cell system 12 required are. A near-mobile part of the non-mobile-mounted power management device includes all functions, such as the outdoor temperature transmitter 60 - Although required for power management by the inventive method in the vicinity of the mobile space, but not for the self-sufficient operation of the fuel cell system 12 , Apart from the communication functions required for the overall 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.

4 outlines a cross-section shown in perspective 80 and a perspective side view 82 a partially cut rope according to the invention 16 which preferably has at least one Seale-type strand. This surrounds the fuel hose 29 together with parallel-guided strands 84 an inner strand of the rope 16 helically. The structure thus formed constitutes an inner crate 86 dar. The inner Kardeel 86 is in turn from an outer layer of strands 88 surrounded helically. This also applies to the fuel hose 29 , In a preferred embodiment, all strands are 84 . 88 in the match wound. To squeeze the fuel hose 29 To prevent this, periodically use a spacer 90 , in particular with a metal or plastic ring 90 be equipped. As in 4 shown, it is it is independent of it but also possible the outer layer of strands 88 in a relation to the inner layer of strands 84 to execute opposite direction of impact. In this construction, a cage-like structure, whereby the outer layer of strands 88 stronger on the inner strands 84 supported, since they are less compliant than the fuel hose 29 , A similar effect can also be achieved in that the outer layer of strands 88 is executed with a different stroke length than the outer one. Some rope constructions have considerable gaps in cross section 92 on, which are preferably filled with plastic, for example, on the circumference of the inner Kardeel 86 a tubular plastic intermediate layer is applied or applied. Due to the fact that metal surfaces of the stranded layers 84 . 88 then no longer can touch directly and no longer damage by direct chafing of metal against metal, can the durability of the rope 16 be improved. To damage the fuel hose 29 By preventing such events, the fuel hose can 29 , Which consists of a plastic suitable for fuel, to be sheathed with a hose or grid-like protective sheath, not shown, of another plastic, which has better mechanical properties for this purpose. Some rope constructions are cross-sectioned 80 very large spaces filled with plastic 92 on.

It seems quite possible in one or more such spaces 92 instead of the plastic one cable each 31 or a fuel hose 29 embed. With a suitable design can also be thought of the fuel hose 29 as a central soul 94 arrange it and with one or two layers of strands 84 . 88 to wrap helically. The entire rope construction can with a protective cover 98 or a protective braid 98 be covered, the then also a part of the rope 16 forms.
