DESCRIPTION OF EMBODIMENTS

[0053] Identical reference numbers used in different figures designate identical, corresponding or functionally similar elements.

[0054] FIG. 1 schematically shows a known electric charging pillar with a stationary fuel cell. It is illustrated how a stationarily installed fuel cell can be operated to generate the energy required for hydrogen production as efficiently and decentrally as possible. In this regard, combined heat and power plants are used to generate the electrical energy; district heating or electricity from the power network can also be used here. The fuel cell can also be supplied with primary energy through connection to the natural gas network. It is important here that the electric filling station is in a place that allows the use of waste heat from an industrial or commercial or residential area.

[0055] FIG. 2 schematically shows an embodiment of a charging station 100 according to the invention from the front. As can be seen from FIG. 2, the illustrated charging station 100 has an elongated housing structure 160 in the form of a kiosk. In other words, this is a small building with projecting roofings on three sides that serve as rain protection for users of the charging station. Furthermore, FIG. 2 shows that the illustrated charging station is provided with three electrical connections 120 or connection panels at the front which, for example, can be used for charging e-bikes 201 (loads 200). For this purpose, the electrical connections 120 or connection panels can be provided with ordinary socket connections, USB connections or other common electrical connections.

[0056] On the left side in FIG. 2, the charging station is provided with a fluid-conducting connection 130 which, for example, can be used for filling a vehicle with hydrogen. However, the connection 130 shown here also has an electrical connection which can be used, for example, to charge an accumulator of an electric vehicle. Furthermore, a defibrillator 195 is provided on the left side of the housing structure 160.

[0057] As can be seen from FIG. 3, the illustrated charging station 100 is equipped with a photovoltaic system 162 that is provided on a roof 161 of the housing structure 160. In this manner, the charging station can gain additional electrical energy that can be supplied to the loads 200 or an electrolyzer for hydrogen production. Moreover, the electrical energy thus obtained can be temporarily stored in an accumulator. A fresh food vending machine 163 is provided at the rear of the illustrated charging station 100, which, using the electrical energy generated in the charging station, can provide, for example, hot baked goods such as baguettes. In addition, the rear of the charging station 100 is provided with a storage space 164 in which a plurality of (full or empty) pressure storages can be provided for sale or replacement.

[0058] FIG. 4 schematically shows the charging station 100 according to the invention of FIG. 2 from the side, the side wall not being shown for better illustration. As is apparent from FIG. 4, an exchangeable device 150 is provided or parked inside the charging station 100, in particular inside the housing structure 160, which in the embodiment shown is configured in the form of a vehicle trailer. This is a vehicle trailer with a known drawbar for attachment to a vehicle as well as a chassis with a twin axle. Provided on the vehicle trailer is a lightweight structure in which a plurality of fuel storages 110, preferably four or six fuel storages, are accommodated, which are combined to form a high-pressure storage system and can be connected via a quick coupling to a supply system, in particular a hydrogen supply system, of the charging station 100. The vehicle trailer is further provided with known safety technology such as thermal pressure relief valves (TPRDs) and the like. The individual fuel storages, in particular high-pressure hydrogen storages, are configured to receive compressed fuel at pressures of up to 1200 bar.

[0059] In order to be able to accommodate the vehicle trailer 150 within the housing structure 160, the housing structure 160 is provided with a roll-up door (not shown) on the left side which allows access to the interior of the housing structure 160. As is further apparent from FIG. 4, the housing structure 160 in this embodiment is built as a modular system of individual modules which can thus be quickly assembled and disassembled, with which the charging station 100 is configured as a so-called mobile charging station that can be set up according to the requirements at different locations such as pedestrian zones, exhibition centers, fairs and the like.

[0060] Further provided within the charging station 100, in particular the housing structure 160, are a hydrogen fuel cell 140 (not shown) as well as an accumulator (not shown) which constitute parts of the supply system or hydrogen supply system of the charging station 100. In this manner, the hydrogen stored in the fuel storages 110 can be used to generate electrical energy, in particular electric current, which can be provided to the loads 200 via the electrical connections 120.
