    专利说明:

    [0001] The present invention relates to a method of filling tanks with pressurized gas. The invention relates more particularly to a method for filling tanks with pressurized gas, in particular hydrogen under pressure, via a filling station comprising at least one pressurized gas source and a fluid transfer circuit of the gas from the at least one source to the tanks, the circuit comprising a first end connected to the at least one gas source and a second end provided with a transfer line for detachably connected to the tanks to be filled, the circuit comprising, arranged in series between the first end and the second end, a first isolation valve, a flow or pressure regulating device, a heat exchanger for cooling the gas transferred to the reservoir to be filled and a second isolation valve the method comprising successively filling a first tank and then a second separate tank.
    [0002] The invention is advantageously applicable to fast filling (a few minutes) of hydrogen tanks under pressure (between 200 and 1000 bar for example). The invention is particularly applicable to the filling of fuel tanks of vehicles. When filling a hydrogen tank with gas under pressure, the compression of the gas in the tank produces a heating that can exceed the limits of use of the materials of the tank. It is thus generally necessary to pre-cool the gas before it is introduced into the tank. SAE J2601 provides examples of conditions in which it is recommended that a tank be filled. For this, the filling station must be able to supply cooled gas to the target temperature range as soon as filling is started. In certain situations, the start-up and cooling-down time of the cooling equipment after a certain waiting period between the filling of two vehicles may lead to a filling start with insufficiently cold gas. The beginning of the filling phase of such a tank is however critical since it is necessary to cool the lines of the filling circuit and to carry out generally a connection test which is preferably carried out with a cold gas. SAE J2601 gives more favorable filling recommendations if the lines are cold at the beginning of filling.
    [0003] An object of the present invention is to overcome all or part of the disadvantages of the prior art noted above. For this purpose, the method according to the invention, moreover in accordance with the generic definition given in the preamble above, is essentially characterized in that, at the end of the filling of the first reservoir, the first and second 10 isolation are closed to trap a reserve of gas under pressure in the circuit between these two valves and in that the gas supply is used for filling the second tank. The present invention provides an arrangement and use of the lines of the filling circuit to improve the start of filling.
    [0004] Indeed, at the end of a completed filling, instead of evacuating all the gas present in the lines of the filling circuit downstream of the control member (control valve) via a discharge to the For example, the invention retains at least part of this cold and pressurized gas and uses it during subsequent filling.
    [0005] That is to say that the pressurized gas situated at the downstream end of the line (at the level of the hose connected to the reservoir to be filled, in particular downstream of the second valve) is purged to allow the disconnection of the downstream end of the hose relative to the filled tank but the gas located further upstream between this downstream part and the regulating member (between the second valve 11 and the first valve 7) can be stored and reused. Furthermore, embodiments of the invention may include one or more of the following features: - the gas reserve is used to perform a leak test of the second tank sealingly connected to the second end of the circuit The gas reserve is used to perform a circuit leak test, the gas reserve is used during a determination phase of at least one physical characteristic of the tank such as its volume, its 3033867 3, its internal pressure, its filling ratio, said determination phase being carried out via the injection of pressurized gas from the reserve of gas trapped in the circuit towards the inside of the second tank and measuring at least one size the physical gas in the reservoir after the injection, the physical quantity of the gas being selected from: the temperature, the pressure within the reservoir, the trapped gas e Between the two isolation valves is under the conditions of temperature and pressure corresponding to the last filling phase of the first tank, the gas trapped between the two isolation valves has a pressure of between 200 and 1000 bar and preferably between 700 and 900 bar and a temperature between 0 ° C and minus 41 ° C and preferably between minus 10 ° C and minus 30 ° C, - the first isolation valve is arranged in the circuit in a manner adjacent to the heat exchanger, i.e. the first isolation valve is closer to the heat exchanger than the first end of the circuit and preferably the first isolation valve is located at the level of the exchanger inlet, the second isolation valve is disposed in the circuit adjacent the second end of the circuit, i.e. the second isolation valve is closer from the second end of cir the volume of the circuit situated between the first and second isolation valves is between 0, 00005m3 and 0.01m3, or more, for example up to 0.05 m3 or 25 0. , 1 m3 or more, for example 1 m3. the length of the circuit between the first and second isolation valves is between one meter and fifty meters and preferably between two and thirty meters, at least between the first and second isolation valves the circuit comprises one or pipes comprising thermal insulation. The invention may also relate to any alternative device or method comprising any combination of the above or below features.
    [0006] Other features and advantages will appear on reading the description below, with reference to the single figure which shows schematically and partially, an example of a gas filling station that can implement the invention.
    [0007] The filling station illustrated schematically comprises at least one source 2, 3, 4 of gas under pressure and a fluid transfer circuit of the gas from the at least one source to the tanks 1 to be filled. The at least one source 2, 3, 4 may comprise for example at least one of: a pressurized gas storage or pressure storage 10 arranged in parallel, one or more compressors ... The station 100 may in particular use several pressure tanks for filling by successive pressure balances ("cascade") with the tank to fill (possibly supplemented or assisted by a compressor). For example, documents FR2928716A1 and WO2015001208A2 which describe in more detail examples of the structure and operation of filling stations can be referred to. The circuit 5 comprising at least a first end connected to at least one gas source 2, 3, 4 (upstream side) and a second end (downstream side) provided with a transfer pipe 6, in particular a flexible pipe, intended to be 20 removably connected to the tanks 1 to fill. The circuit 5 comprises, arranged in series from upstream to downstream, between the first end and the second end: a first isolation valve 7, a flow or pressure regulating member 8 (expander, flow control valve, controlled expansion valve, proportional type valve or any other suitable device), a heat exchanger 9 for cooling the gas transferred to the reservoir 1 to be filled and a second isolation valve 11. The exchanger 9 is an organ in which the gas is cooled to the target temperature. Of course, the arrangement of several exchangers having different structures for carrying out this cooling can be envisaged.
    [0008] After the cooling member 9 and the second isolation valve 11, the downstream end of the circuit may comprise in known manner sensors, flexible and connectors to connect to the tanks 1 of the vehicles to be filled.
    [0009] The schematic representation of the figure depicts a minimum of components. Of course, the circuit 5 may conventionally include other equipment such as valves, sensors ... interposed or not between the components shown in FIG. Similarly the order of the components can be changed. For example, the first isolation valve 7 can be located between the regulating member 8 and the exchanger 9 or even downstream of the exchanger 9. The station can be used as follows. During a filling of the tank 1 of a first vehicle, called "first tank", the end of the filling process of the tank 1 takes place 10 generally around the maximum filling pressure (between 700 bar and 875 bar for example). ) with a cooling temperature within the recommended ranges (eg between -17 ° C and -40 ° C). Once the first tank 1 is completely filled, the filling station 100 can control the closing of the valves 7, 11 of isolation of the distribution line.
    [0010] The cooling member 9 is preferably placed in a predefined mode of waiting mode of the next vehicle. That is, a cooling circuit supplying frigories to exchanger 9 can be shut down or maintained at a maximum cooling rate or at a reduced cooling rate with respect to its maximum cooling.
    [0011] In this way, in the waiting phase of the next vehicle, the entire line or lines of the circuit 5 located between the two isolation valves 7, 11 remain in pressure and cooled temperature. That is to say that a reserve of gas under pressure and cold is trapped in the circuit 5.
    [0012] Thus, when the next vehicle is presented the line of the circuit 5 is kept cold (with the exception of heat losses). The filling of the tank 1 of this second vehicle ("second tank" 1) can be achieved. Conventional preliminary tests (prior to filling according to the recommendation of SAE J2601 or in accordance with any other filling logic or filling standard specific to each operator of a filling station) can be performed with the trapped gas. In particular, the gas can be used to perform conventional leak tests with sufficient pressure and also with a cold temperature.
    [0013] This makes it possible to start the filling of the next tank with a gas that is already cold and under pressure. In this way also, a significant part of the lines of the circuit 5 is thus already pre-cooled. This makes it possible to avoid or limit the start-up time of the cooling system and the preliminary phase, where the exchange between the gas to be cooled and the exchanger is not yet stabilized. This also makes it possible to limit the devices which make it possible to prepare pre-cooled gas before filling, such as, for example, maintaining the cooling system at full speed or the presence of a pre-cooling loop in permanent operation. In the case for example of a filling of a first tank 1 which ends after a period of between 3min and 5min. At the end of this filling, the isolation valves 7, 11 are closed. The downstream end of the distribution line (particularly flexible) connected to the vehicle can be emptied of its gas (downstream of the second isolation valve 11). On the other hand, between the two valves 7, 11 of isolation the length of the circuit can be typically between two meters and thirty meters. This portion is thus filled with hydrogen for example at a pressure between 700 bar and 875 bar and a temperature that can typically be between -40 ° C and -17 ° C.
    [0014] This line is preferably insulated. This thermal insulation is adapted to minimize heat losses can maximize and extend the effects of the invention. After a waiting time typically of one to twenty minutes, the gas may have warmed slightly, but remains in a cold temperature range (-40 ° C to -17 ° C for example). A second vehicle may appear at the station 100. The user can perform the connection and authentication of his vehicle. The filling is then launched for example by pressing a button or a start indicator.
    [0015] The first filling step comprising, for example, a leak test, and / or a determination of the characteristics of the reservoir and the conditions of the filling line can be achieved with the gas contained between the isolation valves 7, 11 (especially via the opening of the second valve 11).
    [0016] After or during use of the trapped gas, the process of filling the second tank 11 can continue with the pressurized gas from the source (s) 2, 3, 4.
