Definitions
- the invention relates to a method for filling a vehicle tank with a fuel, in particular hydrogen.
- the pressure tank is usually regarded as a thermally insulated system (but not adiabatic) (installation-dependent in the vehicle). If the tank is thermally insulated, it must be filled with hydrogen at very low temperatures (for example around -40 ° C). Also the max. Pressure ramps are limited accordingly. As a result, much effort has to be made in terms of heat exchange, pressure ramp control and electronic monitoring in the high pressure area of the filling to the appropriate
- the maximum permissible temperature of the pressure-bearing components or the tank (usually fiber materials, plastics, metals) must be observed. Since it must be assumed in a thermally insulated system that the heat is evenly distributed in the tank, there are also increased temperatures at these critical points.
- the present invention seeks to provide a method of the type mentioned, which is at least partially improved in terms of the aforementioned disadvantages.
- Fuel is filled, and wherein the tank is cooled during and / or after filling of the tank with the vehicle by means of a coolant. Due to the particular direct cooling during refueling, the resulting
- Heat can be better dissipated with advantage. This makes the system less susceptible to overheating due to refueling.
- the temperature generated during refueling can be kept below the permissible temperatures of the components of the vehicle, in particular of the tank.
- the refueling can thus in particular without
- Subcooling of the fuel to be refueled e.g., gas, especially hydrogen.
- the heat generated during the filling is preferably removed and, in particular, any possibly existing heat imbalance (hot soak) is reduced.
- the cooling can be done by means of cooling liquid (water) or all kinds of cooling media (gas, air, ). Accordingly, the said coolant preferably has one of the following substances or is formed by one of the following substances: a gas, in particular air, water.
- the method according to one embodiment provides that the coolant is conducted to the tank in the form of a coolant flow and / or applied thereto, wherein in particular the coolant is led from the outside (ie outside of the vehicle) to the tank or placed thereon.
- the coolant in this case contact the tank or another component of the vehicle, which is thermally conductively connected to the tank.
- the coolant or the coolant flow can furthermore be guided or cooled in an open or a closed cooling system.
- Cooling system i.e., a cooling system provided outside the vehicle
- a cooling system provided outside the vehicle
- the cooling system has one or more nozzles which are configured to pressurize the tank or another component of the vehicle, which is in heat-conducting connection with the tank (see in particular above), with the coolant or the coolant flow ,
- the cooling of the tank with the coolant or coolant flow in each case that is basically carried out. Furthermore, it is provided according to an embodiment of the invention that the
- Cooling of the tank with the coolant and in particular the filling of the tank with the coolant is only started when or after the vehicle is in a predefined position with respect to the particular fixed cooling system.
- the cooling or filling of the tank will not start until, after or after the vehicle is in such a position relative to the nozzles, that the nozzles actually engulf the tank or said component (see above) with the coolant can apply.
- a corresponding bearing or position determination of the vehicle can be carried out by radio.
- an optical detection (light or marking) or a geometric fixation of the vehicle is possible, for example by a means for generating a fixed parking position of the vehicle, for example one or more shots and / or elevations in the ground for one or more vehicle wheels of the vehicle ,
- the nozzle (s) for applying the coolant or coolant flow can be variably (ie adjustable) but also arranged rigidly.
- an underbody of the vehicle is designed so that the coolant flow through the subfloor or by means provided on the subfloor (for example, one or more
- Impact areas or baffles is directed to the points or tank to be cooled.
- the cooling medium can be actively cooled by means of the cooling system through the environment or else.
- the direct cooling of the tank from below can also be realized by a guided cooling flow, baffles or a closed circuit.
- the coolant in the case of a gaseous coolant by means of one or more fans of the
- Cooling system and / or via gas ducts is brought to the tank. Furthermore, all cooling methods mentioned herein can also be combined with each other. Thus, e.g. in addition to pressurizing the tank with the (e.g., liquid) coolant via one or more nozzles, further (e.g., gaseous) cooling means may be brought to the tank to be cooled by alternative methods (e.g., by means of said fans or gas ducts, respectively).
- further (e.g., gaseous) cooling means may be brought to the tank to be cooled by alternative methods (e.g., by means of said fans or gas ducts, respectively).
- the medium flowing back during the cooling can also be used for detecting the tank condition or the tank temperature by monitoring the temperature change of the cooling medium, which in turn allows conclusions about the filling level of the tank. In visible from below or exposed tanks can according to a
- the current tank temperature are also detected by IR temperature measurement, the cooling or the coolant flow can be controlled so that the tank reaches or does not exceed a certain temperature.
- Fig. 1 is a schematic representation of a method according to the invention.
- FIG. 1 shows an embodiment of a method according to the invention.
- Hydrogen powered motor vehicle 1 can act, it is preferably parked in a defined position with respect to a nozzle 4 of a cooling system 3.
- the cooling system 3 is configured to cool the coolant W, here e.g. Provide water, cooled and give up the nozzle 4 to a tank 2 of the vehicle 1, the tank is particularly firmly connected to the vehicle 1.
- the nozzle 4 is directed in the said parking position on the tank 2 and acts on this with the coolant 2, namely at and / or after filling the tank 2 (which may have a plurality of chambers) with the fuel K.
- the underbody 5 of Vehicle 1 can also be designed so that the coolant W is deflected from this in the direction of the tank 2.
- the cooling system 3 preferably has a device for collecting the ejected through the nozzle 4 and used for cooling the tank 2 coolant W, for example in the form of a sunk in the bottom receptacle 6, which may be covered, for example, by a coolant-permeable grating 7.
- the coolant W flowing back and forth from the tank 2 can then be collected in the receptacle 6, cooled again by the cooling system 3 and discharged again through the nozzle 4.
- the degree of filling or state of the tank 2 can be determined, for example, by evaluating the tank temperature.
- the tank temperature can be measured directly, especially with an open tank 2 (eg by IR temperature measurement).
- the temperature of the returning coolant W can also be evaluated in order to conclude the tank temperature or the tank condition.
- W coolant especially water
