TECHNICAL FIELD
[0001] The invention relates to a compressed-gas-storage-receiver device for a motor vehicle, which compressed-gas-storage-receiver device is used to cool a compressed-gas storage. BACKGROUND
[0002] Fuel cell vehicles, which obtain electric drive energy from a fuel, such as hydrogen, are an alternative to conventional combustion engine vehicles and battery electric vehicles. Similar to a full fill-up of a conventional combustion engine vehicle, a full fill-up of a fuel cell vehicle takes 3 to 5 minutes. Hydrogen, for example, can be stored in compressed-gas storage, so-called gas tanks, which are cylindrical in the case of fuel cell vehicles. When a fuel cell vehicle is filled up at a filling station, fuel flows from the gas storage of the filling station into the compressed-gas storage of the motor vehicle. The fuel in the compressed-gas storage is compressed during the filling process, wherein the compression energy is released in the form of heat. This results, on the one hand, in the fuel itself warming up and the pressure of the fuel in the compressed-gas storage thus additionally increasing. On the other hand, the compressed-gas storage also warms up. Here, the fuel pressure in the compressed-gas storage should not be higher than a critical compressed-gas-storage pressure, and the temperature of the compressed-gas storage should not be higher than a critical compressed-gas-storage temperature. In the case of hydrogen, therefore, the filling process is prescribed worldwide by the filling protocol according to SAE TIR J2601.
[0003] It is known that the fuel at the filling station is pre-cooled to -40 degrees Celsius in order to counteract the warming up of the fuel during the filling process. The filling time can thus be shortened, however, the pre-cooling is associated with high costs. Furthermore, the compressed-gas storages are fitted in the vehicle such that these compressed-gas storages are mostly surrounded by air, so that only very poor heat dissipation via the outer jacket surface of the compressed-gas storage is achieved during the filling process. SUMMARY
[0004] The invention shows a compressed-gas-storage-receiver device, a system with a motor vehicle and a cooling device, a filling station and a method for filling up a motor vehicle.
[0005] Here, the features and details described in the context of the compressed-gas-storage-receiver device according to the invention of course also apply in the context of the system according to the invention, the filling station according to the invention and the method according to the invention, and vice versa accordingly, so that in the disclosure of the individual invention aspects always or can be mutually referred to.
[0006] According to a first aspect, the present invention relates to a compressed gas storage receiving device for a motor vehicle, which is used to cool a compressed gas storage device. The compressed gas storage receiving device comprises a main body having a plurality of channel-shaped receiving surfaces for receiving a compressed gas storage device. The main body is heat-conducting and has fastening interfaces for being arranged on corresponding fastening interfaces of the vehicle body. In addition, the main body has heat-conducting surfaces for being connected to the vehicle body in a thermally connected manner. In addition, the compressed gas storage receiving device comprises a compressed gas storage device for storing gas under high pressure, wherein the compressed gas storage device is heat-conducting and is received by the main body in a form-fitting manner on the channel-shaped receiving surfaces of the main body for thermal connection.
[0007] With the compressed gas reservoir receiving device according to the present invention, the heat generated during the filling process can be particularly advantageously conducted (in particular, transferred) from the heat-conducting compressed gas reservoir via the heat-conducting body to the vehicle body. Because the vehicle body can have a large thermal mass and a large surface area, the heat generated during the filling process can be particularly easily, quickly, and efficiently dissipated, for example, to the environment. To this end, the heat-conducting body of the compressed gas reservoir receiving device has a receiving surface for positively receiving the compressed gas reservoir. This can particularly advantageously ensure that the heat generated during the filling process is conducted from the compressed gas reservoir, in particular from the casing of the compressed gas reservoir and thus also from the pressurized gas in the compressed gas reservoir, to the heat-conducting body or transferred via the heat-conducting body to the vehicle body. This advantageously ensures that the critical compressed gas reservoir pressure and critical compressed gas reservoir temperature for the respective compressed gas reservoir are not exceeded. Consequently, risks to vehicle occupants, such as the risk of the compressed gas reservoir exploding, can be minimized. Furthermore, the compressed gas storage tank receiving device according to the present invention allows for a particularly short filling time for a full filling of the compressed gas storage tank due to the particularly effective thermal connection between the compressed gas storage tank and the vehicle body. Furthermore, the time during the filling process during which the fuel flow must be interrupted, as is required in a filling protocol according to SAE TIR J2601, can be omitted. This means that the compressed gas storage tank receiving device according to the present invention allows for continuous filling of the compressed gas storage tank of a motor vehicle.
[0008] The heat-conducting body can particularly advantageously absorb heat generated during the filling process from the compressed gas reservoir via the channel-shaped receiving surface, conduct this heat, and dissipate it to the body of the motor vehicle. The heat-conducting body can be constructed from metal. A metal body can have particularly high thermal conductivity. In particular, the metal body can be at least partially composed of steel, thereby simultaneously ensuring particularly high stability of the body. In particular, the metal body can be composed entirely of steel. The heat-conducting body can also be formed at least partially from a plastic with a highly heat-conducting filler. Such a body can be particularly lightweight while also having high thermal conductivity and can be manufactured particularly cost-effectively and simply.
[0009] The phrase "the compressed gas reservoir is received in a form-fitting manner on the channel-shaped receiving surface of the main body" can be understood to mean that the compressed gas reservoir and the channel-shaped receiving surface are at least partially designed to complement each other. Preferably, the complementary surfaces are in contact with each other, so that thermal communication between the compressed gas reservoir and the receiving surface is particularly advantageous.
[0010] The compressed gas storage device can be designed essentially as a hollow cylinder, which can be referred to as a known gas cylinder. The heat-conducting compressed gas storage device can be made of metal. The metal compressed gas storage device can each have a particularly high thermal conductivity. In particular, the metal compressed gas storage device can each be made at least partially of steel and can thus ensure a particularly high stability of the compressed gas storage device. In particular, the metal compressed gas storage device can each be made entirely of steel. The heat-conducting compressed gas storage device can also each be made at least partially of plastic (which has a highly heat-conducting filler). Such a heat-conducting compressed gas storage device can have a particularly low weight while having a high thermal conductivity and can be manufactured particularly cost-effectively and simply. Therefore, the heat generated during the filling process can be particularly advantageously conducted from the compressed gas storage device via the heat-conducting body to the body of the motor vehicle.
[0011] Furthermore, the compressed gas storage device may include, in particular, a plurality of individual compressed gas storage devices. These may be fluidically interconnected. Advantageously, compared to a single, large compressed gas storage device, a plurality of individual, particularly small, compressed gas storage devices may achieve an overall larger outer envelope surface for the same storage volume. Furthermore, given the same storage volume, the plurality of individual compressed gas storage devices may collectively have a greater thermal mass than a single, larger compressed gas storage device. The thermal mass of a compressed gas storage device may be understood as the mass of the compressed gas storage device casing, in particular the tank casing. In other words, the thermal mass may be understood as the mass of the envelope surrounding the compressed gas (e.g., hydrogen) in the compressed gas storage device. The heat generated during the filling process can therefore be particularly advantageously absorbed by the particularly large thermal mass of the plurality of individual compressed gas storage devices. Furthermore, advantageously, compared to a single, large compressed gas storage device, a plurality of individual, particularly small, compressed gas storage devices may enable the construction of a particularly flat compressed gas storage device receiving device for the same storage volume. Such a flat compressed gas reservoir receiving device (in particular the main body of the compressed gas reservoir receiving device) can particularly advantageously form part of the vehicle body, in particular the vehicle floor. This can save costs, and the heat generated during the filling process can be particularly advantageously dissipated, on the one hand, through the main body itself, and on the other hand, to the remaining parts of the vehicle body.
[0012] Multiple channel-shaped receiving surfaces can be understood, in particular, to mean multiple channel-shaped receiving surfaces arranged side by side and / or one behind the other. In particular, the side-by-side receiving surfaces can be spaced apart from one another. This ensures that compressed gas reservoirs received in the side-by-side receiving surfaces are optimally accommodated therein and, in particular, do not contact one another. This ensures that, even in the event of thermal expansion of the compressed gas reservoir, the compressed gas reservoir remains positively received by the main body of the compressed gas reservoir receiving device. Multiple channel-shaped receiving surfaces arranged side by side and / or one behind the other provide a particularly large surface for receiving the compressed gas reservoir. Consequently, a particularly large amount of heat generated during the filling process of the compressed gas reservoir can be absorbed, conducted, and discharged to the vehicle body by the particularly large surface, in particular the channel-shaped receiving surfaces. Furthermore, the multiple channel-shaped receiving surfaces arranged side by side and / or one behind the other allow the heat-conducting main body to be particularly flat. The channel-shaped receiving surfaces of the main body and the outer casing surface of the compressed gas reservoir can each have, at least partially, the same shape in cross-section. The channel-shaped receiving surfaces can each exhibit a circular arc in cross-section. The compressed gas reservoir can be designed essentially as a hollow cylinder, while the outer jacket surface of the compressed gas reservoir can each be circular in cross-section. The circular arc-shaped receiving surface can therefore be particularly advantageous for receiving a hollow cylindrical compressed gas reservoir and can therefore particularly advantageously conduct heat to the heat-conducting body during the filling process. This can thus be particularly advantageous for cooling the compressed gas reservoir. It is also conceivable for the channel-shaped receiving surface to be groove-shaped. The groove can have a rectangular parallelepiped shape in cross-section. The rectangular parallelepiped-shaped receiving surface can particularly advantageously receive a rectangular parallelepiped compressed gas reservoir and can therefore facilitate thermal communication between the compressed gas reservoir and the channel-shaped receiving surface.
[0013] The fastening interface can have holes for inserting screws. The corresponding fastening interface of the vehicle body can have correspondingly arranged holes, in particular the crossbeams and / or longitudinal beams of the vehicle body can have correspondingly arranged holes. The main body of the compressed gas storage reservoir receiving device can be arranged on the vehicle body with the aid of screws and nuts. Such an arrangement can be particularly easy to implement. It is also possible to arrange the fastening interface of the main body of the compressed gas storage reservoir receiving device on the corresponding fastening interface of the vehicle body by welding. This allows a particularly stable arrangement to be achieved. In particular, an arrangement by welding can be particularly advantageous when the main body of the compressed gas storage reservoir receiving device is to form part of the vehicle body.
[0014] A heat-conducting surface of the main body can be understood as a surface of the main body that can particularly effectively conduct heat from the main body to the vehicle body. The heat-conducting surface can particularly effectively contact the vehicle body, resulting in a particularly low thermal resistance between the vehicle body and the heat-conducting surface. The vehicle body can also have a corresponding heat-conducting surface, particularly opposite the heat-conducting surface of the main body of the compressed gas storage device. In particular, the thermal resistance between the vehicle body and the heat-conducting surface can be lower than the thermal resistance at other contact points between the vehicle body and the main body of the compressed gas storage device, such as at the fastening interface and the corresponding fastening interface. In other words, heat can be better conducted, particularly transferred, at the heat-conducting surface. Using the heat-conducting surface of the main body, and particularly in conjunction with the corresponding heat-conducting surface of the vehicle body, heat from the compressed gas storage device can be particularly targeted and directed to particularly advantageous areas of the vehicle body, enabling particularly efficient heat dissipation. Cooling of the compressed gas storage device can thus be achieved particularly effectively. It is also conceivable for the fastening interface of the main body of the compressed gas storage device to have, or in particular, form, a heat-conducting surface. In this case, the corresponding fastening interface of the vehicle body can advantageously have a corresponding heat-conducting surface. This allows the heat generated during the filling process to be dissipated from the compressed gas reservoir to the vehicle body in a particularly simple manner. The heat-conducting surface of the main body of the compressed gas reservoir device can have a heat-conducting adhesive, and / or the corresponding heat-conducting surface of the vehicle body can have a heat-conducting adhesive. This allows for a particularly advantageous thermal connection between the main body of the compressed gas reservoir receiving device and the vehicle body. The heat generated during the filling process can thus be particularly advantageously conducted and dissipated to the vehicle body. This allows for particularly effective cooling of the compressed gas reservoir.
[0015] The main body can be box-shaped. The box-shaped body can be particularly advantageously mounted between two longitudinal beams of a vehicle body, so that heat generated during the filling process can be particularly advantageously dissipated via the main body to the vehicle body. The box-shaped body can have an interior space, wherein the box-shaped body includes a plurality of channel-shaped receiving surfaces within the interior space. The box-shaped body can have a convex edge on its outer side that surrounds the box-shaped body. This convex edge can form a fastening interface.
[0016] High-pressure gas can be understood to mean a fuel, such as hydrogen, which is compressed to, for example, 700 to 800 bar or is compressed to 700 to 800 bar in a compressed gas reservoir during the filling process. The compressed gas reservoir receiving device according to the present invention can also be used for other compressible fuels. In particular, the compressed gas reservoir receiving device according to the present invention can be used to dissipate the heat of compression generated during the compression of the gas.
[0017] Advantageously, in the compressed gas reservoir receiving device according to the present invention, at least 15% of the outer envelope surface of each compressed gas reservoir, preferably at least 25% of the outer envelope surface, is received on a corresponding channel-shaped receiving surface of the main body for thermal communication with the main body. If the compressed gas reservoir receiving device receives at least 15% of the outer envelope surface of each compressed gas reservoir on the corresponding channel-shaped receiving surface of the main body for thermal communication with the main body, particularly effective cooling of the compressed gas reservoir can be achieved. Even more effective cooling of the compressed gas reservoir can be achieved if the compressed gas reservoir receiving device receives at least 25% of the outer envelope surface of each compressed gas reservoir on the corresponding channel-shaped receiving surface of the main body for thermal communication with the main body. At least 15% or at least 25% of the outer envelope surface of each compressed gas reservoir can be a continuous surface. Advantageously, the channel-shaped receiving surface of the heat-conducting main body, in particular the heat-conducting main body of the compressed gas reservoir receiving device, can be configured such that the main body / the channel-shaped receiving surface receives a continuous surface of the corresponding compressed gas reservoir. This allows particularly effective heat conduction from the corresponding continuous surface of the outer casing of the compressed gas reservoir into the heat-conducting body. This allows for localized heat dissipation from the compressed gas reservoir. It is also conceivable that at least 15% or at least 25% of the outer casing surface of each compressed gas reservoir is comprised of at least two mutually separate surfaces of the corresponding outer casing. The heat-conducting body, in particular the channel-shaped receiving surface of the heat-conducting body, can be configured so that it / the channel-shaped receiving surface receives a receiving surface of the corresponding compressed gas reservoir, each comprised of at least two mutually separate surfaces. For example, such a heat-conducting body can have free space for this purpose. In particular, each of the channel-shaped receiving surfaces of the heat-conducting body can have free space. Advantageously, the body can have the corresponding channel-shaped receiving surfaces evenly distributed along the longitudinal direction of each compressed gas reservoir and / or evenly distributed along the circumference of each compressed gas reservoir. The heat generated by the compressed gas storage device during the filling process can therefore be absorbed particularly evenly by the heat-conducting body and conducted, in particular transferred, to the body of the motor vehicle.
[0018] Advantageously, in the compressed gas storage receiving device according to the invention, the main body can have at least one of the following elements:
[0019] - heat-conducting elements for cooling the main body, in particular cooling ribs and / or cooling channels and / or cooling plates,
[0020] a heat-conducting elastic element between the compressed gas reservoir and the channel-shaped receiving surface, which serves to compensate for thermal expansion of the compressed gas reservoir,
[0021] - Reinforcement elements for stabilizing the body.
[0022] Heat-conducting elements (particularly cooling ribs and / or cooling channels and / or cooling plates) can, in particular, provide additional thermal communication between the heat-conducting body and the vehicle body. The heat-conducting elements can reduce the thermal resistance between the vehicle body and the heat-conducting body. Heat can thus be discharged from the compressed gas storage device via the body to the vehicle body in an improved manner. The heat-conducting elements, particularly the cooling ribs and / or cooling channels and / or cooling plates, can be made of a heat-conducting material. The heat-conducting material can be metal. For example, additional sheet metal can be guided from the body to the vehicle body. Metallic heat-conducting elements, particularly cooling ribs and / or cooling channels and / or cooling plates, can also contribute to the stability of the vehicle body. The heat-conducting material can also be a plastic with a highly heat-conducting filler. Such heat-conducting elements, particularly cooling ribs and / or cooling channels and / or cooling plates, can be particularly lightweight. Furthermore, the heat-conducting elements can be integrally formed with the heat-conducting body. This ensures that the thermal resistance between the heat-conducting elements and the heat-conducting body is kept particularly low. The heat-conducting elements can also be arranged separately on the heat-conducting body. Furthermore, the cooling ribs and / or cooling channels and / or cooling plates can particularly advantageously dissipate heat from the heat-conducting body to a fluid (e.g., water or air). Heat generated during the filling process can thus be particularly advantageously conducted from the compressed gas reservoir via the heat-conducting body, in particular transferred to the vehicle body, because the thermal resistance of the heat-conducting body can be kept low by the cooling ribs and / or cooling channels and / or cooling plates.
[0023] Advantageously, the heat-conducting elastic element between the compressed gas reservoir and the channel-shaped receiving surface enables improved thermal communication between the heat-conducting main body and the heat-conducting compressed gas reservoir. Furthermore, the heat-conducting elastic element can compensate for thermal expansion of the corresponding compressed gas reservoir. Furthermore, the heat-conducting elastic element can be integrally formed with the heat-conducting main body. This keeps the thermal resistance between the heat-conducting elastic element and the main body low. The heat-conducting elastic element can also be constructed separately and attached to the main body. In particular, the channel-shaped receiving surfaces of the main body can each comprise or form a heat-conducting elastic element. This makes it possible to particularly advantageously compensate for thermal expansion of the compressed gas reservoir and ensure that the compressed gas reservoir is received in a form-fitting manner by the main body during the filling process. This ensures that heat can be particularly effectively conducted from the compressed gas reservoir via the heat-conducting main body, in particular, dissipated to the vehicle body, during the filling process. The heat-conducting elastic element can be made of an elastic, heat-conducting plastic. Such a heat-conducting elastic element is particularly easy to manufacture and can have particularly favorable thermal conductivity.
[0024] The main body can have a plurality of reinforcement elements. Advantageously, the reinforcement elements of the main body can ensure that the compressed gas storage device is received in a particularly advantageous form-fitting manner on the channel-shaped receiving surface of the main body for thermal communication. In addition, the reinforcement elements can fix the compressed gas storage device (received in the corresponding receiving surface) to prevent movement. The reinforcement element can be made of a heat-conducting material and can keep the thermal resistance of the heat-conducting main body low. This means that the thermal mass of the heat-conducting main body can be increased by the additional heat-conducting material of the reinforcement element, and the heat of the compressed gas storage device can therefore be received and discharged particularly advantageously. In addition, the reinforcement element can be constructed for being arranged on the body of the vehicle, and / or the reinforcement element can be arranged on the main body. Therefore, the reinforcement element can further improve the transport of heat from the tank to the main body and the vehicle body. In particular, the space between the reinforcement element and the main body can be configured so that optimized heat transport from the compressed gas storage device to the main body is achieved.
[0025] According to a second aspect, the present invention relates to a system comprising a motor vehicle and a cooling device for cooling a vehicle body. The motor vehicle comprises a compressed gas reservoir receiving device according to the present invention and also comprises a vehicle body having a corresponding fastening interface, wherein the heat-conducting body of the compressed gas reservoir receiving device is arranged on the corresponding fastening interface by means of the fastening interface.
[0026] The vehicle body can have a plurality of corresponding fastening interfaces. The heat-conducting body of the compressed gas storage device can also have a plurality of corresponding fastening interfaces. The compressed gas storage device can be arranged below the passenger compartment of the motor vehicle. It is also conceivable that the compressed gas storage device forms at least a part of the bottom of the motor vehicle. The vehicle body can have longitudinal beams and transverse beams. The longitudinal beams and / or transverse beams can have, in particular form, the corresponding fastening interfaces. In particular, the compressed gas storage device is arranged between two longitudinal beams and / or between two transverse beams of the vehicle body. Therefore, the thermally connected connection between the heat-conducting body, in particular the heat-conducting surface, and the vehicle body can have a particularly low thermal resistance. As a result, heat can be transferred from the compressed gas storage device particularly efficiently, in particular, conducted away from the vehicle body. The heat can be conducted away from the vehicle body via the ambient air. This can constitute a particularly advantageous and effective solution.
[0027] A motor vehicle may include a fuel cell system. The fuel cell system may include a fuel cell stack including fuel cells. The fuel cell system may also include an air compressor for supplying compressed air to the fuel cell stack. The fuel cell system may also include a cooling circuit for cooling the fuel cell system, in particular the fuel cell stack.
[0028] Particularly advantageously, in the system according to the invention, the cooling device can comprise a fan of the motor vehicle and a cooling air conducting element for conducting cooling air conveyed by the fan to the body of the motor vehicle, and / or the cooling device can comprise a cooling circuit of the motor vehicle and a cooling fluid conducting element for conducting cooling fluid to the body of the motor vehicle. Such cooling devices can also be understood as internal cooling devices.
[0029] The fan of the motor vehicle can in particular be one of the following fans:
[0030] - Fan for liquid cooling of the motor,
[0031] - a blower fan for ventilating the interior of a motor vehicle,
[0032] -Air compressors for fuel cell systems in motor vehicles.
[0033] The fan of the liquid cooling system for the motor can be understood as the main cooler fan of the vehicle. The vehicle fan can also be the air compressor of the vehicle's fuel cell system. The air compressor can deliver cooling air at a particularly high pressure or flow rate to the vehicle body. This allows for particularly efficient heat dissipation. The vehicle fan can be used to cool the vehicle body in a particularly simple and cost-effective manner using the cooling air delivered by the fan. The cooling air can thus be used to dissipate heat generated during the filling process particularly effectively from the compressed gas reservoir, particularly from the vehicle body. The cooling air conducting element can conduct the cooling air from the fan to the vehicle body, thereby dissipating heat away from the vehicle body. The cooling air conducting element can include a duct between the fan and the vehicle body, through which the cooling air flows from the fan to the vehicle body. The cooling air conducting element can also include multiple ducts as fluidic connections between the fan and the vehicle body. These ducts can direct the cooling air to different locations on the vehicle body. In particular, the cooling air can be directed by the cooling air conducting element to locations on the vehicle body that have a particularly high temperature compared to other locations on the vehicle body. This allows for particularly efficient heat dissipation and, in particular, cooling of the compressed gas reservoir via the vehicle body. It is also conceivable that the cooling air be directed, via the cooling air conducting element, to a location on the vehicle body where the heat-conducting body is positioned with its heat-conducting surface against the vehicle body. The cooling air conducting element can also conduct the cooling air to heat-conducting elements of the heat-conducting body of the compressed gas reservoir receiving device. Heat dissipation can thus be particularly advantageous. Advantageously, the cooling air can also be directed by the vehicle's fan via the cooling air conducting element to the heat-conducting body and / or the compressed gas reservoir, thereby enabling additional heat dissipation.
[0034] The cooling circuit of the motor vehicle can be one of the following cooling circuits:
[0035] - a cooling circuit for cooling a motor or power electronics of a motor vehicle,
[0036] - a refrigeration circuit for air conditioning a motor vehicle, in particular a refrigeration circuit of an air conditioner of a motor vehicle,
[0037] - A cooling circuit for cooling the fuel cell system.
[0038] The vehicle body can be cooled using a cooling fluid in a particularly simple and cost-effective manner using the vehicle's cooling circuit. Heat generated during the filling process can thus be particularly advantageously dissipated from the compressed gas reservoir, in particular, from the compressed gas reservoir to the vehicle body via a heat-conducting body. The heat can be dissipated via the cooling fluid. A cooling fluid conducting element can conduct the cooling fluid to the vehicle body, thereby dissipating the heat away from the vehicle body. Preferably, cooling air from a fan, in particular a main cooler fan, can be conducted to the cooling fluid conducting element using the cooling air conducting element. This allows additional cooling of the cooling fluid in the cooling fluid conducting element and particularly efficient heat dissipation from the vehicle body. The cooling fluid conducting element can be a pipe that conducts the cooling fluid from the vehicle's cooling circuit to the vehicle body. The cooling fluid conducting element can also include multiple pipes, wherein the pipes direct the cooling fluid to different locations on the vehicle body. The cooling fluid conducting element can also include cooling hoses, wherein the cooling hoses are arranged on the vehicle body and / or around the compressed gas reservoir. The cooling fluid conducting element can also conduct the cooling fluid to the heat-conducting elements of the heat-conducting body of the compressed gas storage device. This allows for particularly advantageous heat dissipation. In particular, the cooling fluid can be conducted via the cooling fluid conducting element to locations on the vehicle body where the vehicle body has a particularly high temperature compared to the rest of the vehicle body. This allows for particularly efficient heat dissipation and, in particular, cooling of the compressed gas storage device via the vehicle body. It is also conceivable that the cooling fluid can be conducted via the cooling fluid conducting element to locations on the vehicle body where the heat-conducting body is positioned relative to the vehicle body via its heat-conducting surface. Advantageously, the cooling fluid can also be directed to the heat-conducting body and / or the compressed gas storage device via the cooling air conducting element, thereby enabling additional heat dissipation. Particularly cold cooling fluid can be conducted to the vehicle body via a refrigeration circuit, in particular the refrigeration circuit of the vehicle's air conditioner.
[0039] According to a further preferred embodiment of the system according to the application, the cooling device can have an external cooling element for cooling the vehicle body of the motor vehicle, wherein the cooling element can be arranged in the region of the motor vehicle and the cooling element is one of the following elements:
[0040] - an external fan,
[0041] - an external water spraying device for spraying the motor vehicle with water,
[0042] - an external cooling chamber.
[0043] The external cooling element can be arranged in front of, behind, below and / or above the motor vehicle. The external cooling element is preferably arranged below the motor vehicle, so that heat can be particularly effectively conducted away from the vehicle body of the motor vehicle by the cooling element. The external cooling element is to be understood as meaning a cooling element which can be carried along with the motor vehicle, but which is not fixedly connected to the motor vehicle in the normal state of the motor vehicle, like a fixedly arranged main cooling fan of the motor vehicle. For example, a mobile fan can be carried in the luggage compartment of the motor vehicle, which mobile fan can be removed from the luggage compartment during refuelling. The external water spraying device can particularly effectively cool the vehicle body of the motor vehicle during refuelling, since water can store heat better than air under the same conditions. In addition, water can additionally extract heat when evaporating on the vehicle body and thus cool the vehicle body. The motor vehicle can have a fuel cell, wherein, advantageously here, the external water spraying device uses water produced by the operation of the fuel cell of the motor vehicle for spraying. It is also conceivable that the water spraying device sprays a heat-conducting body and / or a compressed-gas storage tank of a compressed-gas storage receiving device with water, so that heat is additionally conducted away and it can particularly advantageously be ensured that heat produced during refuelling is conducted from the compressed-gas storage and thus also from the gas under pressure in the compressed-gas storage to the heat-conducting body or is transmitted to the vehicle body of the motor vehicle via the heat-conducting body. Furthermore, the refuelling station can also have this external cooling element.
[0044] The system according to the second aspect of the application thus has the same advantages as have already been described for the compressed-gas storage receiving device according to the first aspect of the application.
[0045] According to a third aspect, the present invention provides a filling station for a system according to the present invention having a motor vehicle and a cooling system. The filling station has a parking area for parking the motor vehicle. Furthermore, the filling station has a filling station control unit having a data interface for data communication with a corresponding data interface of the motor vehicle. Furthermore, the filling station control unit is configured at least to detect an active filling process state of the motor vehicle based on the data communication between the data interface and the corresponding data interface, and to activate the cooling system for cooling the vehicle body when an active filling process state is detected.
[0046] The filling station may include a compressed gas reservoir shunt pump in the station's storage area for providing high-pressure gas. The compressed gas reservoir shunt pump may include a filling hose, wherein the filling hose has a data interface for data communication with a corresponding data interface of the vehicle. The vehicle may have a corresponding data interface on the filler neck. The data interface and the corresponding data interface may be infrared interfaces. The vehicle may be in an active filling process state when the vehicle is parked in the storage area, the vehicle is stationary, the vehicle's fuel cell or fuel cell system is not in operation, and the compressed gas reservoir shunt pump is fluidically connected to the compressed gas reservoir of the compressed gas reservoir receiving device. The filling station control unit may use the data interface to send data to the corresponding data interface of the vehicle to activate a cooling system, particularly one of the vehicle's fans and / or one of the vehicle's cooling circuits, to cool the vehicle body. The filling station control unit may also, for example, activate an external cooling element of the cooling system via an electrical wire, particularly if the filling station includes such an external cooling element. Activating the fan may be understood as switching the fan on. When the cooling circuit is activated, the cooling circuit pump of the cooling circuit can be switched on. The cooling device can be controlled as a function of the temperature of the compressed gas storage tank and / or the temperature of the heat-conducting body of the compressed gas storage receiving device and / or the temperature of the vehicle body.
[0047] It can be advantageous if, in the filling station according to the invention, the filling station has an external cooling element of a cooling device for cooling the body of the motor vehicle, wherein the cooling element is arranged in the region of the motor vehicle and is one of the following elements:
[0048] - external fan,
[0049] an external water jet system for spraying the motor vehicle with water,
[0050] - External cooling chamber.
[0051] The external cooling elements of a filling station can be arranged in front of, behind, below, and / or above the vehicle. They are preferably arranged below the vehicle so that heat can be removed from the vehicle body particularly effectively via the cooling elements. Compared to vehicle cooling elements, external cooling elements can be designed with particularly high power and therefore can cool the vehicle body particularly effectively. A filling station can have external cooling elements in the parking space. The cooling air delivered by the external fan can be pre-cooled. This means, for example, that the cooling air is pre-cooled by a refrigeration circuit to a temperature that is lower than the temperature of the ambient air. Therefore, the heat generated during the filling process can be particularly effectively removed from the vehicle body and, therefore, from the compressed gas reservoir. The external water spraying system of the filling station can particularly effectively cool the vehicle body during the filling process. Advantageously, the water used to spray the vehicle, particularly the vehicle body, can be pre-cooled. This means, for example, that the water is pre-cooled by a refrigeration circuit to a temperature that is lower than the temperature of the ambient air. Therefore, the heat generated during the filling process can be particularly effectively removed from the vehicle body and, therefore, from the compressed gas reservoir. It is also conceivable to use fluids other than water for spraying the motor vehicle, in particular the vehicle body, for example in winter.
[0052] Advantageously, in the filling station according to the invention, the storage area has a vehicle maintenance pit with a fluid-permeable cover, wherein a cooling device for cooling the body of the motor vehicle is arranged in the vehicle maintenance pit. The vehicle maintenance pit can be constructed on a parking space so that the motor vehicle is located above the vehicle maintenance pit after being parked in the parking space. The parking space can be marked for this purpose. As a result, the cooling device can be used to cool the body of the motor vehicle particularly advantageously, easily, and effectively. The fluid-permeable cover can be a grid, in particular a metal grid. The grid can withstand particularly high loads, such as motor vehicles. Cooling devices, such as fans external to the filling station and / or external water jets, can cool the motor vehicle, in particular the body of the motor vehicle, particularly easily through the grid without significant flow resistance.
[0053] The filling station according to the third aspect of the invention therefore has the same advantages as have already been described for the compressed gas storage receiving device according to the first aspect of the invention or the system according to the second aspect of the invention.
[0054] According to a fourth aspect, the present invention provides a method for cooling the body of a motor vehicle according to the invention when filling a motor vehicle according to the system according to the invention at a filling station according to the invention, wherein the motor vehicle has a corresponding data interface, wherein the method comprises the following steps:
[0055] a) data communication between a data interface of the filling station and a corresponding data interface of the motor vehicle in order to determine the status of the filling process,
[0056] b) recognition of an active filling process status by the filling station control unit,
[0057] c) Activating the cooling device by the filling station control unit and / or by the vehicle control unit in order to cool the body of the motor vehicle and to fill the compressed gas reservoir of the motor vehicle.
[0058] In step a), the motor vehicle can send information to the filling station control unit about the temperature of the vehicle body and / or the temperature of the compressed-gas storage and / or the temperature of the heat-conducting body. Furthermore, the motor vehicle can send information to the filling station control unit about the filling state of the compressed-gas storage. These information can also be sent during the entire filling process. The motor vehicle can also send these information to a controller of the motor vehicle, which can be a vehicle control unit, which is configured to control the cooling device of the motor vehicle. By means of the information listed above, the cooling device of the filling station and / or the cooling device of the motor vehicle can be activated or activated, so that a particularly effective cooling of the motor vehicle, in particular of the vehicle body of the motor vehicle, can be achieved by means of the cooling device. Furthermore, the motor vehicle can send information to the filling station control unit that the motor vehicle, in particular the compressed-gas storage, and the filling station, in particular the compressed-gas storage bypass pump, are fluidically safely connected to one another and that the vehicle is stationary and thus the filling process can be started. A positive filling process state can be understood as information that the filling process can be started. In step b) of the method, the filling station control unit recognizes this positive filling process state. The recognition can be achieved by evaluating data by the filling station control unit. In the next step c), the cooling device is activated by the filling station control unit and in particular the compressed-gas storage of the motor vehicle is filled with gas. The filling station control unit can activate the cooling device of the filling station and / or the cooling device of the motor vehicle. In particular, the filling station control unit can actuate a controller of the motor vehicle, which is configured to control the cooling device of the motor vehicle, wherein the controller in turn activates the cooling device of the motor vehicle. The filling of the compressed-gas storage with gas from the compressed-gas storage bypass pump and the activation of the cooling device can take place simultaneously. Furthermore, the filling station control unit can control the flow rate of the gas flowing from the compressed-gas storage bypass pump into the compressed-gas storage of the motor vehicle, so that the heat generated during the filling process can be particularly advantageously dissipated from the vehicle, in particular from the vehicle body. This can mean that the filling station control unit controls the flow rate of the gas such that in a first time interval at the beginning the flow rate increases, in particular continuously, up to a maximum flow rate value. In a subsequent second time interval, this maximum flow rate value can be maintained for a period of time, and in a subsequent third time interval, the flow rate of the gas can decrease, in particular continuously, in particular to zero. In an additional step of the method, the filling of the compressed-gas storage can be ended. This can mean that no more gas flows from the compressed-gas storage bypass device to the compressed-gas storage of the motor vehicle. In particular, the filling station control unit can deactivate the cooling device, in particular the external cooling elements of the filling station. Deactivation can be understood as switching off.
[0059] Advantageously, in the method according to the present invention, after step c) or after the additional step of completing filling, in step d), the cooling system, preferably the cooling system of the vehicle, is only deactivated when the compressed gas reservoir temperature falls below a definable threshold value. This means that, in particular, the vehicle cooling system can remain active even after the compressed gas reservoir is completed. Thus, even after the filling process, heat can continue to be dissipated from the vehicle, in particular from the vehicle body and / or the compressed gas reservoir and / or the heat-conducting body. This can have the advantage that the compressed gas reservoir can be brought to a temperature below the definable threshold value, thereby minimizing risks to vehicle occupants, such as the risk of a compressed gas reservoir explosion. The definable threshold value is advantageously below a critical compressed gas reservoir temperature. The compressed gas reservoir can also be brought to a pressure below a definable threshold value. The definable threshold value is advantageously below a critical compressed gas reservoir pressure. If the definable temperature threshold and / or definable pressure threshold are fallen below, the vehicle cooling system can be deactivated, in particular by a control unit of the vehicle.
[0060] The method according to the fourth aspect of the invention therefore has the same advantages as already described for the compressed gas storage receiving device according to the first aspect of the invention or the system according to the second aspect of the invention or the filling station according to the third aspect of the invention.

[0073] In the subsequent figures, identical technical features of different embodiments are provided with the same reference signs, even if not all embodiments are shown in each figure.
[0074] Figure 1 An embodiment of a compressed-gas storage receiver device 1 is shown in a perspective view. The compressed-gas storage receiver device 1 has a heat-conducting main body 20, which is made of steel, for example. The main body 20 can be configured in a box shape, wherein the compressed-gas storage 10 is received in a plurality of channel-shaped receiving faces 22 (not visible here) in the interior space of the box-shaped main body 20. The main body 20 has a circumferential, protruding edge 28, which surrounds the box-shaped main body 20. The circumferential, protruding edge 38 is a fastening interface 26 and at the same time a heat-conducting face 24. The fastening interface 26 can have holes for screwing through. The main body 20 can be arranged by means of the fastening interface onto a corresponding fastening interface 126 of a vehicle body 120 of a motor vehicle 100. The compressed-gas storage 10 is heat-conducting and can be configured in a hollow-cylindrical shape, as in Figure 1 For example, the compressed-gas storage 10 can be made of steel and can particularly advantageously store a gas, for example hydrogen, at high pressure. In addition, three reinforcing elements 36 are additionally drawn in Figure 1 in which the compressed-gas storage 10 (received in the respective receiving face 22) is fixed against movement and contributes to the stability of the main body 20. Thus, the heat generated during the filling process can be particularly advantageously conducted away from the compressed-gas storage 10, in particular from the compressed-gas storage 10 via the heat-conducting main body 20 onto the vehicle body 120 of the motor vehicle 100. Figure 2 is shown Figure 1Vertical section A1-A1 of an embodiment of a compressed gas storage receiving device 1 (see Figure 1 The section axis A1-A1). Figure 2 In the embodiment, the heat-conducting compressed gas reservoir 10 is received by the main body 20 in a form-fitting manner on a channel-shaped receiving surface 22 of the main body 20 by means of a corresponding outer jacket surface AM for thermal communication. The channel-shaped receiving surface 22 is designed in the shape of a circular arc.
[0075] Figure 3 Two further embodiments of a compressed gas storage receiving device 1 according to the invention are disclosed in each case in vertical section (see Figure 1 sectional axis A1-A1 in). In both embodiments, the compressed gas storage 10 is received in the channel-shaped receiving surface 22. In addition, these two embodiments have a heat-conducting surface 24 and a fastening interface 26. Another embodiment shown on the left shows a separate heat-conducting element 32, wherein the heat-conducting element 32 is a cooling plate arranged on the main body 20. The heat-conducting element 32 additionally has cooling channels in the cooling plate, through which, for example, a cooling fluid or cooling air can flow. Another embodiment shown on the right shows a heat-conducting element 32, wherein the heat-conducting element 32 is integral with the heat-conducting main body 20. The heat-conducting element 32 also has cooling channels here. In addition, the heat-conducting element 32 includes cooling ribs, through which cooling air can flow and thus additionally can conduct heat away from the heat-conducting main body 20.
[0076] Figure 4 Another embodiment of a compressed gas storage receiving device 1 according to the invention is shown in vertical section (see Figure 1 The section axis A1-A1 in the figure). Figure 4 In the embodiment, the compressed gas storage devices 10 are received in the channel-shaped receiving surfaces 22 arranged side by side. In addition, the channel-shaped receiving surfaces 22 arranged side by side are arranged spaced apart from each other. Therefore, the compressed gas storage devices 10 received in the receiving surfaces 22 do not touch each other. Therefore, it is also possible to ensure that, even in the event of thermal expansion of the compressed gas storage devices 10, the compressed gas storage devices 10 continue to be received in a form-locked manner by the heat-conducting body 20 of the compressed gas storage device receiving device 1. In addition, Figure 4 A heat-conducting elastic element 34 is respectively located between the compressed gas reservoir 10 and the channel-shaped receiving surface 22, thereby compensating for thermal expansion of the respective compressed gas reservoir 10. Thermal expansion of the compressed gas reservoir 10 can occur due to the heat generated during the filling process.
[0077] Figure 5 In another embodiment, a compressed gas storage receiving device 1 according to the invention is shown in vertical section (see Figure 1 The section axis A1-A1 in the Figure 2 External Figure 5 , a reinforcing element 36 is shown. This reinforcing element 36 secures the compressed gas reservoir 10 (received in the corresponding receiving surface 22 ) against movement and contributes to the stability of the body 20 .
