- a pressure vessel system with a pressure vessel assembly for a motor vehicle for storing fuel is known from the prior art. There is a desire to arrange the fuel accumulators of a motor vehicle in the underfloor area below the passenger compartment.
- the installation space calls for new pressure vessel systems that provide several small pressure vessels instead of fewer large pressure vessels. The aim is to accommodate as much fuel as possible in the available installation space without having a noticeable adverse effect on costs, weight or other design parameters.
- Such concepts are known in principle from the following publications:
- the technology disclosed here relates to a pressure vessel system for a motor vehicle (e.g. passenger cars, motorcycles, commercial vehicles).
- the pressure vessel system is used to store fuel that is gaseous under ambient conditions.
- the pressure vessel system can be used, for example, in a motor vehicle that is operated with compressed (also called Compressed Natural Gas or CNG) or liquefied (also called Liquid Natural Gas or LNG) natural gas or with hydrogen.
- the pressure vessel system is fluidly connected to at least one energy converter which is set up to convert the chemical energy of the fuel into other forms of energy.
- the energy converter can be, for example, an internal combustion engine or a fuel cell system or a fuel cell stack.
- Such a pressure vessel system comprises a plurality of pressure vessels, preferably composite overwrapped pressure vessels.
- the pressure vessel can be a high-pressure gas vessel, for example.
- NWP nominal working pressure
- a cryogenic pressure vessel is suitable for storing the fuel at the aforementioned operating pressures even at temperatures that are significantly (eg more than 50 Kelvin or more than 100 Kelvin) below the operating temperature of the motor vehicle.
- the motor vehicle may include a plurality of pressure vessels.
- a pressure vessel assembly (also referred to as a “container assembly”) may include the pressure vessels as well as support, attachment, and/or protective elements (e.g., shields, shields, barriers, covers, coatings, wraps, etc.) permanently connected to the pressure vessels.
- the supporting, fastening and/or protective elements can expediently only be dismantled temporarily and preferably only by specialist personnel and/or cannot be dismantled non-destructively.
- Such a pressure vessel assembly is particularly suitable for flat installation spaces, especially in the underfloor area below the vehicle interior.
- a pressure vessel assembly preferably comprises more than 3 or more than 5 or more than 7 or more than 10 pressure vessels. In the installed position in the motor vehicle, the pressure vessels can be oriented in the vehicle transverse direction or in the vehicle longitudinal direction.
- the pressure vessels can have circular or oval cross-sections.
- the individual pressure vessels can be designed as storage tubes. For example, several pressure vessels can be provided, the longitudinal axes of which run parallel to one another in the installed position.
- the individual pressure vessels can each have a length-to-diameter ratio with a value between 5 and 200, preferably between 7 and 100, and particularly preferably between 9 and 50.
- the length-to-diameter ratio is the quotient of the total length of each pressure vessel (e.g. total length of a storage tube without fluid connectors) in the numerator and the largest outside diameter of the pressure vessel in the denominator.
- the individual pressure vessels can be arranged directly adjacent to one another, for example at a distance from one another of less than 20 cm or less than 15 cm or less than 10 cm or less than 5 cm.
- the multiple pressure vessels are in fluid communication with one another via a common fuel line. It is regularly provided upstream from the (high-pressure) pressure reducer.
- the fuel line is expediently designed to withstand essentially the same pressures as the pressure vessels that are connected to the fuel rail.
- the individual pressure vessels of the pressure vessel assembly are directly fluidly connected to one another via the fuel line or the fuel rail, so that the individual pressure vessels essentially have the same pressure in the intended state according to the principle of communicating tubes.
- the fuel line can preferably be designed as a fuel rail.
- the fuel rail may also be referred to as a high pressure fuel rail.
- such a fuel rail can be configured similarly to a high-pressure injection rail of an internal combustion engine.
- a single tube or a single block or a single housing preferably forms the fuel rail.
- the fuel rail expediently includes a number of rail connections for direct connection of the pressure vessels.
- the individual strip connections are advantageously provided directly on the strip housing or block or pipe and/or all have the same spacing from one another.
- Such a fuel bar is for example in the German patent applications with the application numbers DE 102020 128 607.4 and DE 102020 123037.0 are disclosed, the content of which with regard to the design of the fuel rail (also referred to as a distributor pipe or rail) and the connection of the pressure vessel is hereby incorporated by reference.
- the fuel rail can be designed to be essentially rigid.
- rigid means that the fuel rail is rigid against bending or that in the functional use of the fuel rail there is only an imperceptible and irrelevant bending for the function.
- the fuel rail can be designed in such a way that the fuel rail can compensate for changes in the position of the pressure vessels, and in particular of their connecting pieces.
- Changes in position are deviations between an actual position of the pressure vessel (in operation, during manufacture, during a service call or other situation) and a target position assumed during construction. Changes in position result, for example, from the expansion of the components (eg the pressure vessel) due to changes in internal pressure and/or changes in temperature. Furthermore, changes in position (positional deviations) can occur due to manufacturing tolerances.
- the fuel rail can be set up to enable tolerance compensation perpendicular to the longitudinal axes of the pressure vessel of the pressure vessel system.
- the fuel line or the fuel rail and, as a rule, also the shut-off valve described below is part of the pressure vessel assembly.
- the connection of the pressure vessels to the fuel line or the proximal ends of the pressure vessels can be designed, for example, as disclosed in one of the following documents: DE102018118397 A1, EP3346178 A1,
- At least one thermally activatable pressure relief device can be provided at or immediately adjacent to each end of the fuel line. Adjacent to the end thereby includes the arrangement of the TPRDs at a maximum distance of 0.1 x L, where L is the total length of the fuel rail.
- TPRD thermal pressure relief device
- Thermally activatable pressure relief devices are expediently provided at the ends of the pressure vessels that are distal in relation to the fuel line.
- thermally activatable pressure relief devices can be provided only at the distal ends of the outer pressure vessels.
- local heat sources can thus be easily detected without a thermally activatable pressure relief device being provided at each end of the pressure vessel, so that the manufacturing complexity, the manufacturing costs and the number of sealing points are reduced.
- the pressure relief devices are provided in separate housings, which contain other functional components such as sensors and/or valves in addition to the pressure relief devices. For example, the
- Pressure relief device may be provided in the housing of the shut-off valve disclosed here.
- At least one pressure relief device can include a housing in or on which a temperature sensor is additionally provided, in particular at the distal end. This simplifies assembly and reduces the number of interfaces to be sealed.
- An electrically actuable and normally closed shut-off valve can be provided on the pressure vessel assembly or on the fuel line, which is set up to shut off the pressure vessel assembly or the fuel line from the other fuel-carrying lines of the fuel supply system leading to the energy converter.
- This shut-off valve has the function of an on-tank valve of a conventional pressure vessel. Only one normally closed shut-off valve is expediently provided.
- the shut-off valve can, for example, be screwed directly onto or onto the pressure vessel assembly.
- the shut-off valve (common) is the first valve provided downstream of each of the pressure vessels connected to the common fuel line.
- a pipe rupture valve also known as an excess flow valve, can be provided on any pressure vessel, on the fuel line or in the housing of the shut-off valve.
- the pressure vessels of the pressure vessel assembly are expediently provided on one connection side of the shut-off valve as communicating tubes without a further electrically actuatable shut-off valve, and on the other connection side the rest of the fuel supply system including the energy converter is provided (usually the remaining components of the anode subsystem of a fuel cell system.
- An excessive flow valve and/or the thermally activatable pressure relief device is/are preferably also provided in the housing of the tank shut-off valve.
- the pressure vessel system can also include at least one further pressure vessel for storing fuel.
- the at least one further pressure vessel can have a fuel storage volume that is at least 2 times or at least 3 times or at least 5 times greater than the fuel storage volume of the largest pressure vessel of the pressure vessel assembly. If all pressure vessels in the assembly have the same fuel storage volume, this fuel storage volume shall be used.
- This at least one further pressure vessel is preferably arranged below or behind a seat, in particular the rear bench seat. A particularly large amount of fuel can thus be stored in the motor vehicle.
- the volume ratio has a value between 0.15 and 1.0 or a value between 0.2 and 0.75 or a value between 0.25 and 0.5.
- the volume ratio is the quotient of the fuel volume of the at least one further pressure vessel in the numerator and the total fuel volume of all pressure vessels of the pressure vessel assembly in the denominator. Simulations and tests have shown that in the range of these volume ratios, there are negligibly small overflow processes between the pressure vessel assembly and the additional pressure vessel and at the same time a large amount of fuel can be stored in the vehicle.
- the pressure vessel system may further include at least one underbody chassis mountable to a vehicle body from below.
- the pressure vessel assembly and the underbody chassis can be designed in such a way that the pressure vessel assembly can be inserted or mounted into the underbody chassis from above, with the unit of underbody chassis and pressure vessel assembly being able to be assembled onto the vehicle body from below. This facilitates the assembly and disassembly of the pressure vessel system. Furthermore, the pressure vessel system is thus well protected against the effects of the weather and other environmental influences.
- the ends of the pressure vessels that are proximal in relation to the fuel line are expediently designed as fixed bearings. Furthermore, the ends of the pressure vessels that are distal in relation to the fuel line are advantageously designed as floating bearings. The ends of the pressure vessels are advantageously connected to one another by common holding elements (e.g. cross braces).
- these common holding elements can be designed at the distal end in such a way that the entire holding element moves relative to the fixed bearing in order to compensate for any lengthening.
- the loose bearing is formed in that i) each pressure vessel or ii) only some of the pressure vessels are formed together as a subgroup so that they can be displaced relative to the fixed bearing.
- the fixed bearing/moving bearing principle can be implemented as described in publication US2019047409 AA or in the German patent application with the application number DE 102021 102694.6, the content of which regarding the design of the floating bearing is hereby incorporated by reference.
- the pressure vessels are advantageously arranged essentially between the door sills.
- the underbody chassis can comprise energy-absorbing crash deformation structures on the sides, preferably with framework structures, which are set up to at least reduce the impact energy transmitted to the pressure vessel assembly in the event of a collision.
- the underbody chassis comprises support struts in the floor wall, as disclosed, for example, in EP3667151 A1 or the German patent applications with the application numbers DE 102020 128607.4 and DE 102020 123037.0, the content of which with regard to the design of the support struts (there as “supporting member” or referred to as “fastening elements") and the connection of the pressure vessels is hereby incorporated by reference
- the electrical energy storage device is a device for storing electrical energy, in particular in order to drive at least one electrical (traction) drive machine.
- the energy storage device comprises at least one individual cell that forms the electrochemical energy storage cell. A large number of individual cells is usually provided.
- the energy storage device can be a high-voltage storage device or a high-voltage battery.
- the underbody chassis can be designed to accommodate the pressure vessel assembly and at least one electrical energy storage device and the at least one other pressure vessel, so that the pressure vessel assembly, the electrical energy storage device and the Pressure vessels can be mounted together with the underbody chassis on the motor vehicle.
- a distribution block fire protection device is connected to the rail and contains a TPRD as a subcomponent (see Fig. 3)
- a tank end plug is screwed into each of the outermost flat storage tanks at the distal end of the flat storage tank. It can include as sub-components: a TPRD including vent line and a temperature sensor.
- Any TPRD that is activated is suitably capable of venting the entire fuel contents of the planar module to the environment. It was found in tests and simulations that the temperature development within the pressure vessel assembly disclosed here is comparatively similar when filling and removing and therefore one or two temperature sensors are sufficient to detect the temperature within the pressure vessel assembly.
- the pressure vessel assembly has only one temperature sensor. The only one temperature sensor can preferably be provided in or on or adjacent to the housing of the shut-off valve.
- the senor is provided at or adjacent to the end of the combustion line that is opposite the end of the shut-off valve. This has the advantage that the manufacturing costs are reduced. Furthermore, the interfaces for the TPRDs provided at the distal ends of the pressure vessels can be smaller, since these only have the TPRDs and not an additional temperature sensor. Overall, this has an advantageous effect on the utilization of installation space. Also, no electrical lines have to be routed to the distal ends of the pressure vessels.
- the temperature sensor is expediently integrated in such a way that the temperature sensor is set up to record the temperature both during refueling and during removal.
- the pressure sensor could also be transferred from the pressure-reducing unit to the housing of the shut-off valve.
- the pressure sensor is advantageously provided in such a way that it is provided between the fuel line and the shut-off valve. This means that a pressure measurement can also be carried out when the shut-off valve is closed.
- the missing information about the temperature in the tank can be replaced in particular as follows:
- the tank temperature in the pressure vessels can be calculated using a mathematical model.
- Input signals are the measured pressure and the measured temperature in the fuel line before the shut-off valve.
- the pressure vessels cool down and the pressure drops.
- the determined temperature can be checked for plausibility.
- the tank temperature can be measured with the temperature sensor on the shut-off valve with H2 mass flows from e.g. 1 kg/h.
- the measurement of the tank temperature can preferably be dispensed with.
- a strain signal of a pressure vessel could be available in one variant.
- the signal could come from measuring the change in length, diameter, circumference or volume and sent as an input signal to the tank controller. This means that the pressure in a pressure vessel can be determined.
- only one temperature sensor is provided at a distal end of one of the pressure vessels of the pressure vessel assembly.
- Only one temperature sensor can therefore expediently be provided on or in the pressure vessel assembly, with the only one temperature sensor preferably being provided i) at or adjacent to one of the ends of the fuel line, or ii) being provided at the distal end of a pressure vessel.
