Abstract
Description
[0001] The present invention relates to a mobile reserve hydrogen storage device for a hydrogen-powered vehicle. State of the art
[0002] Hydrogen-powered vehicles are well known. The main advantage of using hydrogen as an energy source is that the only emissions produced during vehicle operation are water, and refueling the vehicle with hydrogen takes only a short time. Refueling takes place at stationary filling stations that have special pumps for hydrogen refueling.
[0003] Unfortunately, such filling stations are not very densely located, so a hydrogen-powered vehicle can break down due to a lack of hydrogen far from one. This must be avoided. The present invention addresses this problem.
[0004] To achieve this objective, the mobile reserve hydrogen storage device is proposed with the features of claim 1. Advantageous developments of the invention are set forth in the subclaims. Disclosure of the invention
[0005] A mobile reserve hydrogen storage system for a hydrogen-powered vehicle is proposed. The reserve hydrogen storage system comprises - a housing, - a storage volume formed in the housing, - at least one connection device for the withdrawal of hydrogen from the storage volume and / or for filling the storage volume with hydrogen.
[0006] The proposed mobile reserve hydrogen storage unit can be carried in the vehicle in a similar way to a reserve canister for liquid fuel, such as gasoline or diesel, so that when the hydrogen tank becomes empty, it can be refilled via the reserve hydrogen storage unit at least to the extent that the vehicle can reach the next stationary hydrogen filling station.
[0007] With the help of the proposed reserve hydrogen storage system, a hydrogen-powered vehicle can be refueled anywhere, thereby increasing the vehicle's range.
[0008] In a further development of the invention, it is proposed that the at least one connection device comprises a nozzle and / or a hose. By means of a connection device designed as a nozzle and / or hose, the reserve hydrogen storage device can be connected to the tank nozzle of the vehicle in order to fill the vehicle's hydrogen tank. The connection device is therefore preferably adapted to the tank nozzle of the vehicle. Since this usually corresponds to a certain standard, this standard can be adopted. For example, the connection device can be designed analogously to the connection device commonly used at filling stations for refueling hydrogen vehicles. If this is the case, a further connection device must be provided for filling the storage volume. This can then be designed analogously to the tank nozzle of the vehicle so that it is compatible with the connection device at the filling station.
[0009] Preferably, at least one, preferably electronic, safety device is integrated into the reserve hydrogen storage unit. This safety device interrupts the withdrawal of hydrogen from the reserve hydrogen storage unit and / or the filling of the reserve hydrogen storage unit with hydrogen in the event of a fault. The safety device can be in the form of a valve and / or a sensor system. For example, a pressure sensor can be installed that monitors the pressure during the withdrawal of hydrogen or during the filling of hydrogen. If a predetermined limit is exceeded, the process is interrupted, for example, by closing a valve.
[0010] Furthermore, at least one warning and / or display device is preferably arranged on or in the housing. The display device enables the reading of target values, for example, the refueling quantity and / or duration. The refueling status can also be displayed and read via the at least one display device. In the event of an error, the error can be indicated via the at least one display device so that countermeasures can be taken. The display can be provided as a graphic, as an illuminated symbol, and / or in plain text. A warning can also be displayed and / or emitted in such a way that it is audible.
[0011] Advantageously, at least one battery is integrated into the reserve hydrogen storage unit. The battery serves as an internal power supply, for example, for the at least one electronic security device and / or for the at least one merchandise and / or display device. The battery can preferably be connected to an external power supply via a connection device. This means that the battery is rechargeable and does not need to be replaced.
[0012] Furthermore, it is proposed that the reserve hydrogen storage device have a preferably wireless communication interface via which data, in particular status data, of the reserve hydrogen storage device can be retrieved. For retrieval, for example, a mobile device can be used, which can be coupled to the reserve hydrogen storage device via the communication interface.
[0013] In addition, the reserve hydrogen storage device can have at least one detection device, for example a quantity counter.
[0014] The reserve hydrogen storage unit can be manufactured in various sizes and offered to drivers of hydrogen vehicles as a backup storage unit, for example, via a hydrogen filling station. Roadside assistance organizations can also be equipped with corresponding reserve hydrogen storage units to enable a stranded vehicle to reach a regular filling station.
[0015] A preferred embodiment of the invention is explained in more detail below with reference to the accompanying drawings. These show: Fig. 1 a schematic representation of a reserve hydrogen storage device according to the invention when refueling a vehicle and Fig. 2 a schematic representation of the reserve hydrogen storage of the Fig. 1 when filling with hydrogen. Detailed description of the drawings
[0016] The one in the Fig. The reserve hydrogen storage device 200 according to the invention for a hydrogen-powered vehicle 100, shown in Figure 1, has a housing in which a storage volume 290 for hydrogen is formed. The storage volume 290 can be connected to a tank nozzle 110 of the vehicle 100 via a connection device in the form of a nozzle 210 and / or via a connection device in the form of a hose 215. The connection device in the form of a hose 215 is optional. The at least one connection device 210, 215 is adapted to the tank nozzle 110 of the vehicle 100, so that hydrogen from the storage volume 290 of the reserve hydrogen storage device 200 flows into a hydrogen tank (not shown) of the vehicle 100. For safety reasons, it can be provided that when the connection is established, it is locked so that no hydrogen can escape to the outside. Only after the connection has been locked can refueling be started - manually or automatically.
[0017] For filling the storage volume 290 with hydrogen, a further connection device in the form of a nozzle 211 is provided. As shown for example in the Fig. As shown in Figure 2, at least one connection device 310, 315 of a hydrogen fuel pump 300 can be connected to this. The at least one connection device of the fuel pump 300 can also be designed as a nozzle 310 and / or hose 315.
[0018] In addition, various other devices are integrated into the illustrated reserve hydrogen storage unit. In the present case, these include various warning and / or display devices 220, 230, 240. The display device 220 serves, for example, to display a connection device 210, 215 that is connected to the fuel filler neck 110 of the vehicle 100 but not locked. Other errors can also be displayed via the warning and / or display device 220. The warning and / or display device 240 emits a visual and / or acoustic warning signal in the event of an error. The warning and / or display device 230 displays the refueling status during refueling. Optionally—in addition to the warning and / or display devices 220, 230, 240—an input device 280 can be provided, by means of which at least one target value, for example the refueling quantity and / or duration, can be specified.
[0019] To retrieve status data, a wireless communication interface 255 is integrated into the reserve hydrogen storage unit 200. This interface is assigned an identification code 256, which enables connection to a mobile terminal device 400.
[0020] Furthermore, the illustrated reserve hydrogen storage device 200 has an internal power supply in the form of a battery 250. This has a connection device 260 for connection to an external power supply, so that the battery 250 can be recharged when needed.
[0021] In addition, at least one safety device 270 can be integrated into the reserve hydrogen storage 200, for example in the form of a pressure sensor.
