Abstract

<P>PROBLEM TO BE SOLVED: To provide a gas filling system and a gas filling apparatus capable of optimizing filling of gas from the gas filling apparatus having a cooling apparatus to a gas tank. <P>SOLUTION: The gas filling apparatus 2 in the gas filling system 1 includes a precooler 18 for cooling hydrogen gas supplied from a gas supply source 11 and discharges the hydrogen gas cooled by the precooler 18 to fill the hydrogen gas into the gas tank 30. The temperature of the hydrogen gas cooled by the precooler 18 is detected by a gas temperature sensor T on the upstream side of the gas tank 30. A flow rate control valve 16 controls a filling flow rate of the hydrogen gas to be filled into the gas tank 30, based on the detected temperature of the hydrogen gas. For example, when the detected temperature of the hydrogen gas is high, the filling flow rate is reduced as compared to that when the detected temperature of the hydrogen gas is low. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

本発明は、例えば車両に搭載されるガスタンクに、例えば水素ステーションに設置されるガス充填装置からガスを充填するガス充填システムに関するものである。   The present invention relates to a gas filling system that fills a gas tank, for example, mounted on a vehicle with gas from, for example, a gas filling device installed in a hydrogen station.

燃料電池車両など、ガスタンクを搭載したガス燃料車両は、燃料ガスの充填時にガスステーションに立ち寄って、ガス充填装置の充填ノズルからガスタンクに燃料ガスを充填される。燃料ガスが水素ガスの場合、充填に伴って温度上昇が起きることが知られている。
そこで、特許文献１に記載の水素ガス充填装置では、水素ガスを冷媒との熱交換により予め冷却する冷却手段（いわゆるプレクーラー）を設け、この冷却した水素ガスをガスタンクに充填することで、充填時間の短縮化を図っている。また、この水素ガス充填装置では、冷却し過ぎた場合の結露の発生を防止するために、水素ガスの供給圧を検出し、その検出結果に基づいて冷却手段への冷媒の供給流量又は温度を制御している。 A gas fuel vehicle equipped with a gas tank, such as a fuel cell vehicle, stops at the gas station when the fuel gas is filled, and the gas tank is filled with the fuel gas from the filling nozzle of the gas filling device. When the fuel gas is hydrogen gas, it is known that the temperature rises with filling.
Therefore, the hydrogen gas filling apparatus described in Patent Document 1 is provided with a cooling means (so-called precooler) for precooling the hydrogen gas by heat exchange with the refrigerant, and filling the gas tank with the cooled hydrogen gas. Time is shortened. Further, in this hydrogen gas filling device, in order to prevent the occurrence of dew condensation when overcooled, the supply pressure of hydrogen gas is detected, and the supply flow rate or temperature of the refrigerant to the cooling means is determined based on the detection result. I have control.

特開２００５−８３５６７JP 2005-83567 A

しかし、例えば複数の燃料電池車両が連続して充填された場合、冷却手段への冷媒の供給流量等を適切に制御できず、冷却手段における冷媒が所定の温度を超える可能性がある。その結果、適正に冷却できていない水素ガスがガスタンクに充填されることになると、充填完了前にガスタンク内の温度が設計温度（例えば８５℃）に上昇するおそれがある。一方で、適正に冷却できていないとして、充填を停止したのでは、ドライバーを待たせてしまう。   However, for example, when a plurality of fuel cell vehicles are continuously filled, the supply flow rate of the refrigerant to the cooling unit cannot be appropriately controlled, and the refrigerant in the cooling unit may exceed a predetermined temperature. As a result, when hydrogen gas that has not been properly cooled is filled in the gas tank, the temperature in the gas tank may rise to the design temperature (for example, 85 ° C.) before filling is completed. On the other hand, if the filling is stopped because the cooling is not properly performed, the driver is made to wait.

本発明は、冷却装置を有するガス充填装置からガスタンクへのガスの充填を最適化できる、ガス充填システム及びガス充填装置を提供することをその目的としている。   An object of the present invention is to provide a gas filling system and a gas filling device that can optimize the filling of gas into a gas tank from a gas filling device having a cooling device.

上記目的を達成するため、本発明のガス充填システムは、ガスタンクと、ガス供給源からのガスを冷却する冷却装置を有してこの冷却装置により冷却されたガスを放出してガスタンクに充填するガス充填装置と、冷却装置により冷却されたガスの温度をガスタンクの上流側で検出する温度センサと、温度センサが検出したガス温度に基づいて、ガスタンクへのガスの充填流量を制御する流量制御装置と、を備えたものである。   In order to achieve the above object, a gas filling system according to the present invention includes a gas tank and a cooling device that cools gas from a gas supply source, and releases the gas cooled by the cooling device to fill the gas tank. A filling device, a temperature sensor for detecting the temperature of the gas cooled by the cooling device on the upstream side of the gas tank, and a flow rate control device for controlling the filling flow rate of the gas into the gas tank based on the gas temperature detected by the temperature sensor; , With.

また、本発明のガス充填装置は、ガス供給源からのガスを冷却する冷却装置を有し、この冷却装置により冷却されたガスを放出してガスタンクに供給するものにおいて、さらに、冷却装置により冷却されたガスの温度をガスタンクの上流側で検出する温度センサと、温度センサが検出したガス温度に基づいて、ガスタンクへのガスの充填流量を制御する流量制御装置と、を備えたものである。   The gas filling device of the present invention has a cooling device that cools the gas from the gas supply source, discharges the gas cooled by this cooling device and supplies it to the gas tank, and further cools by the cooling device. A temperature sensor that detects the temperature of the gas that has been detected upstream of the gas tank, and a flow rate control device that controls the gas filling flow rate to the gas tank based on the gas temperature detected by the temperature sensor.

本発明によれば、冷却装置により冷却されたガスの温度に応じて充填流量を可変できるので、冷却装置の冷却能力に応じた最適な充填が可能となる。これにより、ガスタンク内を安定した状態に保ちつつ、所定の充填量（満充填の場合の充填量と、指定量充填の場合の充填量）をできるだけ短時間で充填することができる。   According to the present invention, since the filling flow rate can be varied according to the temperature of the gas cooled by the cooling device, optimal filling according to the cooling capacity of the cooling device is possible. Thereby, it is possible to fill a predetermined filling amount (a filling amount in the case of full filling and a filling amount in the case of specified amount filling) in as short a time as possible while keeping the gas tank in a stable state.

好ましくは、流量制御装置は、ガス温度が上昇するにしたがって、充填流量を減少させるように制御するとよい。これにより、例えば、連続充填の影響でガス温度が高い場合に、ガスタンク内の温度が設計温度に達するのを抑制しながら、所定の充填量を短時間で充填することが可能となる。一方で、ガス温度が低い場合には、ガス温度が高い場合よりも短時間で所定の充填量を充填することができる。   Preferably, the flow rate control device may control to decrease the filling flow rate as the gas temperature increases. Thereby, for example, when the gas temperature is high due to the effect of continuous filling, it is possible to fill a predetermined filling amount in a short time while suppressing the temperature in the gas tank from reaching the design temperature. On the other hand, when the gas temperature is low, the predetermined filling amount can be filled in a shorter time than when the gas temperature is high.

好ましくは、ガス充填システムは、ガスタンク内の情報を取得するセンサを更に備え、流量制御装置は、センサが取得した情報にも基づいて、充填流量を制御するとよい。こうすることで、充填先であるガスタンク内の状態に適した充填ができる。また、ガスタンク内の情報を検出するので、これを推定する場合に比べて、充填流量の制御を高精度に行うことが可能となる。   Preferably, the gas filling system further includes a sensor that acquires information in the gas tank, and the flow rate control device may control the filling flow rate based on information acquired by the sensor. By doing so, filling suitable for the state in the gas tank as a filling destination can be performed. In addition, since the information in the gas tank is detected, it is possible to control the filling flow rate with higher accuracy than in the case of estimating this information.

より好ましくは、センサは、温度センサ及び圧力センサの少なくとも一つを含むとよい。この構成によれば、例えばガスタンクの温度が高いことが検出された場合に、充填流量を低下させて、ガスタンク内のさらなる温度上昇を抑制することができる。   More preferably, the sensor may include at least one of a temperature sensor and a pressure sensor. According to this configuration, for example, when it is detected that the temperature of the gas tank is high, it is possible to reduce the filling flow rate and suppress further temperature increase in the gas tank.

好ましくは、ガスタンクが複数あり、センサがガスタンクごとに情報を取得する場合、流量制御装置は、センサが取得した情報のうちガスタンク内の温度が最も大きい又は圧力が最も小さいガスタンクの情報に基づいて、充填流量を制御するとよい。こうすることで、全てのガスタンクについて、設計温度に達するのを抑制しながら、短時間で所定の充填量を充填することができる。   Preferably, when there are a plurality of gas tanks and the sensor acquires information for each gas tank, the flow rate control device is based on the information on the gas tank having the highest temperature or the lowest pressure in the gas tank among the information acquired by the sensor. The filling flow rate may be controlled. By doing so, it is possible to fill a predetermined filling amount in a short time while suppressing reaching the design temperature for all the gas tanks.

好ましくは、温度センサは、冷却装置でのガス温度を検出するものであるとよい。これにより、冷却装置でのガス温度に基づいて、充填を最適化することができる。   Preferably, the temperature sensor may detect a gas temperature in the cooling device. Thereby, filling can be optimized based on the gas temperature in a cooling device.

別の好ましい実施態様によれば、温度センサは、ガス充填装置からガスタンクに放出された後のガス温度を検出するものであるとよい。これにより、冷却されたガス温度の検出値に対して、ガス充填装置内の外乱の影響を考慮しなくて済む。つまり、ガスタンク内の状態に最も影響する充填直前のガス温度を検知できるので、充填流量を精度良く制御することができる。   According to another preferred embodiment, the temperature sensor may detect the gas temperature after being released from the gas filling device to the gas tank. Thereby, it is not necessary to consider the influence of the disturbance in the gas filling device with respect to the detected value of the cooled gas temperature. That is, since the gas temperature immediately before filling that most affects the state in the gas tank can be detected, the filling flow rate can be accurately controlled.

また、他の好ましい実施態様によれば、ガス充填システムは、充填に際してガスタンクとガス充填装置とを接続するための接続ユニットを更に備え、温度センサは、接続ユニットでのガス温度を検出するものであるとよい。こうすることで、上記同様に、冷却されたガス温度の検出値に対する外乱の影響をできるだけ排除することができる。また、接続ユニットを有効に利用して温度センサを設けることも可能となるなど、応用性も高めることができる。   According to another preferred embodiment, the gas filling system further comprises a connection unit for connecting the gas tank and the gas filling device during filling, and the temperature sensor detects the gas temperature at the connection unit. There should be. By doing so, as described above, the influence of disturbance on the detected value of the cooled gas temperature can be eliminated as much as possible. In addition, the applicability can be enhanced, for example, it is possible to provide a temperature sensor by effectively using the connection unit.

より好ましくは、接続ユニットは、ガスタンク側のレセプタクルと、レセプタクルに接続されるガス充填装置側の充填ノズルと、を備え、温度センサは、充填ノズル又はレセプタクルでのガス温度を検出するものであるとよい。   More preferably, the connection unit includes a receptacle on the gas tank side and a filling nozzle on the gas filling device side connected to the receptacle, and the temperature sensor detects a gas temperature at the filling nozzle or the receptacle. Good.

好ましくは、本発明のガス充填システムは、温度センサが検出したガス温度に基づいて充填流量が制御されている又は制御された旨を表示する表示装置を、更に備えるとよい。この場合、表示装置は、ガス充填装置、又はガスタンクを搭載した移動体に設けられることが好ましい。このような構成によれば、ガス充填装置又は移動体にて、冷却装置の冷却能力に応じた最適な充填がなされていること又はなされたことを視覚を通じて確認することができる。   Preferably, the gas filling system of the present invention may further include a display device for displaying that the filling flow rate is controlled or controlled based on the gas temperature detected by the temperature sensor. In this case, it is preferable that the display device is provided in a gas filling device or a moving body equipped with a gas tank. According to such a configuration, it is possible to visually confirm that the gas filling device or the moving body is filled or optimally filled according to the cooling capacity of the cooling device.

以下、添付図面を参照して、本発明の好適な実施形態に係るガス充填システムについて説明する。ここでは、ガス充填システムとして、燃料電池システムを搭載した燃料電池車両に対して、水素ガスをガス充填装置から充填する例を説明する。なお、燃料電池システムは、公知のとおり、燃料ガス（例えば水素ガス）と酸化ガス（例えば空気）の電気化学反応によって発電する燃料電池などを備える。   Hereinafter, a gas filling system according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings. Here, an example in which hydrogen gas is charged from a gas filling device to a fuel cell vehicle equipped with a fuel cell system will be described as a gas filling system. As is well known, the fuel cell system includes a fuel cell that generates power by an electrochemical reaction between a fuel gas (for example, hydrogen gas) and an oxidizing gas (for example, air).

図１に示すように、ガス充填システム１は、例えば水素ステーションなどに設置されるガス充填装置２と、ガス充填装置２から水素ガスを供給される車両３と、を備える。   As shown in FIG. 1, the gas filling system 1 includes a gas filling device 2 installed in, for example, a hydrogen station, and a vehicle 3 to which hydrogen gas is supplied from the gas filling device 2.

図２に示すように、ガス充填装置２は、水素ガスを貯蔵するカードル（ガス供給源）１１と、水素ガスを車載のガスタンク３０に向けて放出する充填ノズル１２と、これらを結ぶガス流路１３と、を有する。充填ノズル１２は、充填カップリングとも称される部品であり、水素ガスの充填に際して、車両３のレセプタクル３２に接続される。充填ノズル１２とレセプタクル３２によって、ガス充填装置２とガスタンク３２とを接続する接続ユニットが構成される。   As shown in FIG. 2, the gas filling device 2 includes a curdle (gas supply source) 11 for storing hydrogen gas, a filling nozzle 12 for discharging the hydrogen gas toward a vehicle-mounted gas tank 30, and a gas flow path connecting them. 13. The filling nozzle 12 is a component also referred to as a filling coupling, and is connected to the receptacle 32 of the vehicle 3 when filling with hydrogen gas. The filling nozzle 12 and the receptacle 32 constitute a connection unit that connects the gas filling device 2 and the gas tank 32.

ガス流路１３には、カードル１１側から順に、カードル１１からの水素ガスを圧縮して吐出する圧縮機１４と、圧縮機１４によって所定圧力まで昇圧された水素ガスを蓄えておく蓄圧器１５と、蓄圧器１５からの水素ガスの流量を調整する流量制御弁１６と、水素ガスの流量を計測する流量計１７と、ガス流路１３を流れる水素ガスを予備冷却するプレクーラ１８と、プレクーラ１８の下流側にて水素ガスの温度を検出する温度センサＴと、が設けられる。また、ガス充填装置２は、通信機２１、表示装置２２、外気温センサ２３及び制御装置２４を備え、制御装置２４に各種の機器が電気的に接続される。なお、図示省略したが、蓄圧器１３又はその下流側には、充填時にガス流路１３を開く遮断弁が設けられる。   In the gas flow path 13, a compressor 14 that compresses and discharges the hydrogen gas from the curdle 11 in order from the curdle 11 side, and a pressure accumulator 15 that stores the hydrogen gas that has been pressurized to a predetermined pressure by the compressor 14. A flow control valve 16 that adjusts the flow rate of hydrogen gas from the pressure accumulator 15, a flow meter 17 that measures the flow rate of hydrogen gas, a precooler 18 that precools the hydrogen gas flowing through the gas flow path 13, and a precooler 18 And a temperature sensor T for detecting the temperature of the hydrogen gas on the downstream side. The gas filling device 2 includes a communication device 21, a display device 22, an outside air temperature sensor 23, and a control device 24, and various devices are electrically connected to the control device 24. Although not shown, a shutoff valve that opens the gas flow path 13 at the time of filling is provided on the pressure accumulator 13 or on the downstream side thereof.

流量制御弁１６は、電気的に駆動される弁であり、駆動源として例えばステップモータを備える。流量制御弁１６は、制御装置２４からの指令に従って、ステップモータにより弁開度が変更されることで、水素ガスの流量を調整する。これにより、ガスタンク３０への水素ガスの充填流量が制御される。この制御された充填流量が流量計１７によって計測され、その計測結果を受けて所望の充填流量となるように、制御装置２４は、流量制御弁１６をフィードバック制御する。なお、流量制御弁１６以外の流量制御装置を用いることも可能である。   The flow control valve 16 is an electrically driven valve and includes, for example, a step motor as a drive source. The flow rate control valve 16 adjusts the flow rate of hydrogen gas by changing the valve opening degree by a step motor in accordance with a command from the control device 24. Thereby, the filling flow rate of hydrogen gas into the gas tank 30 is controlled. The controlled filling flow rate is measured by the flow meter 17, and the control device 24 feedback-controls the flow rate control valve 16 so as to obtain a desired filling flow rate based on the measurement result. It is also possible to use a flow rate control device other than the flow rate control valve 16.

プレクーラ１８は、熱交換により、蓄圧器１５からの室温程度である水素ガスを所定の低温（例えば−２０℃）に冷却する。プレクーラ１８による熱交換の形式としては、隔壁式、中間媒体式及び蓄熱式のいずれも用いることができ、構造としては公知のものを適用することができる。一例を挙げると、プレクーラ１８は、水素ガスが流れる管路部を有し、この管路部を冷媒が流れる容器に収容することで、水素ガスと冷媒との間で熱交換を行う。この場合、容器への冷媒の供給量及び供給温度を調整することで、水素ガスの冷却温度を調整するようにしてもよい。このようにして、プレクーラ１８により冷却された水素ガス温度は温度センサＴにて検出され、その検出信号が制御装置２４に入力される。   The precooler 18 cools hydrogen gas, which is about room temperature, from the pressure accumulator 15 to a predetermined low temperature (for example, −20 ° C.) by heat exchange. As a form of heat exchange by the precooler 18, any of a partition type, an intermediate medium type, and a heat storage type can be used, and a known structure can be applied. For example, the precooler 18 has a pipe line part through which hydrogen gas flows, and heat exchange is performed between the hydrogen gas and the refrigerant by housing the pipe part in a container through which the refrigerant flows. In this case, you may make it adjust the cooling temperature of hydrogen gas by adjusting the supply amount and supply temperature of the refrigerant | coolant to a container. Thus, the temperature of the hydrogen gas cooled by the precooler 18 is detected by the temperature sensor T, and the detection signal is input to the control device 24.

通信機２１は、例えば、赤外線通信等の無線通信を行う通信インターフェースを有する。表示装置２２は、充填中における充填流量の情報など、各種情報を画面に表示する。表示装置２２は、所望の充填量などを選択又は指定するための操作パネルを表示画面に具備するものであってもよい。   The communication device 21 includes a communication interface that performs wireless communication such as infrared communication. The display device 22 displays various information such as information on the filling flow rate during filling on the screen. The display device 22 may include an operation panel for selecting or specifying a desired filling amount on the display screen.

制御装置２４は、内部にＣＰＵ，ＲＯＭ，ＲＡＭを備えたマイクロコンピュータとして構成される。ＣＰＵは、制御プログラムに従って所望の演算を実行して、種々の処理や制御を行う。ＲＯＭは、ＣＰＵで処理する制御プログラムや制御データを記憶し、ＲＡＭは、主として制御処理のための各種作業領域として使用される。制御装置２４は、図２において一点鎖線で示した制御線にて接続されている通信機２１等のほか、カードル１１、圧縮機１４、蓄圧器１５及びプレクーラ１８とも電気的に接続されており、ガス充填装置２全体を統括制御する。また、制御装置２４は、ガス充填装置２にて把握可能な情報を通信機２１を用いて、車両３に送信する。   The control device 24 is configured as a microcomputer having a CPU, a ROM, and a RAM inside. The CPU executes a desired calculation according to the control program and performs various processes and controls. The ROM stores control programs and control data to be processed by the CPU, and the RAM is mainly used as various work areas for control processing. The control device 24 is electrically connected to the curdle 11, the compressor 14, the pressure accumulator 15, and the precooler 18 in addition to the communication device 21 and the like connected by the control line indicated by the one-dot chain line in FIG. Overall control of the gas filling device 2 is performed. In addition, the control device 24 transmits information that can be grasped by the gas filling device 2 to the vehicle 3 using the communication device 21.

車両３は、上記したガスタンク３０及びレセプタクル３２を備える。ガスタンク３０は、燃料電池への燃料ガス供給源であり、例えば３５ＭＰａ又は７０ＭＰａの水素ガスを貯留可能な高圧タンクである。ガスタンク３０内の水素ガスは、図示省略した供給管路を介して燃料電池に供給される。一方、ガスタンク３０への水素ガスの補給は、ガス充填装置２からレセプタクル３２及び充填管路３４を介して行われる。充填管路３４には、例えば、水素ガスの逆流を防止するための逆止弁３６が設けられる。温度センサ４０及び圧力センサ４２は、ガスタンク３０内の水素ガスの温度及び圧力をそれぞれ検出するものであり、供給管路又は充填管路３４に設けることができる。   The vehicle 3 includes the gas tank 30 and the receptacle 32 described above. The gas tank 30 is a fuel gas supply source to the fuel cell, and is a high-pressure tank capable of storing, for example, 35 MPa or 70 MPa hydrogen gas. Hydrogen gas in the gas tank 30 is supplied to the fuel cell via a supply line (not shown). On the other hand, replenishment of hydrogen gas to the gas tank 30 is performed from the gas filling device 2 through the receptacle 32 and the filling pipeline 34. In the filling line 34, for example, a check valve 36 for preventing a backflow of hydrogen gas is provided. The temperature sensor 40 and the pressure sensor 42 detect the temperature and pressure of the hydrogen gas in the gas tank 30, respectively, and can be provided in the supply line or the filling line 34.

また、車両３は、ガス充填装置２の通信機２１との間で各種情報を送受信する通信機４４と、ガス充填装置２の制御装置２４と同様にマイクロコンピュータとして構成された制御装置４６と、各種情報を画面に表示する表示装置４８と、を備える。通信機４４は、通信機２１に対応した形式のものであり、例えば、赤外線通信等の無線通信を行う通信インターフェースを有する。通信器４４は、充填ノズル１２をレセプタクル３２に接続した状態で通信機２１との間で通信できるように、レセプタクル３２に組み込まれるか、あるいは車両３のリッドボックス内に固定される。制御装置４６は、温度センサ４０及び圧力センサ４２を含む各種のセンサの検出結果を受けて、車両３を統括制御する。また、制御装置４６は、車両３にて把握可能な情報を通信機４４を用いて、ガス充填装置２に送信する。表示装置４８は、例えばカーナビゲーションシステムの一部としても用いることが可能なものである。   Further, the vehicle 3 includes a communication device 44 that transmits and receives various kinds of information to and from the communication device 21 of the gas filling device 2, a control device 46 that is configured as a microcomputer like the control device 24 of the gas filling device 2, And a display device 48 that displays various types of information on a screen. The communication device 44 is of a format corresponding to the communication device 21 and has a communication interface for performing wireless communication such as infrared communication. The communicator 44 is incorporated in the receptacle 32 or fixed in the lid box of the vehicle 3 so that communication with the communication device 21 is possible with the filling nozzle 12 connected to the receptacle 32. The control device 46 receives the detection results of various sensors including the temperature sensor 40 and the pressure sensor 42 and comprehensively controls the vehicle 3. In addition, the control device 46 transmits information that can be grasped by the vehicle 3 to the gas filling device 2 using the communication device 44. The display device 48 can be used as a part of a car navigation system, for example.

上記のガス充填システム１において、車両３に水素ガスを充填する場合、先ず、充填ノズル１２をレセプタクル３２に接続する。この状態にて、ガス充填装置２を作動させる。すると、蓄圧器１５に貯められていた水素ガスが、プレクーラ１８によって冷却された後、充填ノズル１２からガスタンク３０へ放出されて充填される。
本実施形態のガス充填システム１では、冷却された水素ガス温度に応じた充填流量の制御を行っている。 In the gas filling system 1 described above, when the vehicle 3 is filled with hydrogen gas, first, the filling nozzle 12 is connected to the receptacle 32. In this state, the gas filling device 2 is operated. Then, the hydrogen gas stored in the pressure accumulator 15 is cooled by the precooler 18 and then discharged from the filling nozzle 12 to the gas tank 30 and filled.
In the gas filling system 1 of this embodiment, the filling flow rate is controlled according to the cooled hydrogen gas temperature.

次に、図３のフローチャートを参照して、ガス充填システム１における充填流量の制御について説明する。   Next, the control of the filling flow rate in the gas filling system 1 will be described with reference to the flowchart of FIG.

先ず、充填作業者によって、上記の充填ノズル１２とレセプタクル３２の接続作業がなされ、ガス充填装置２からガスタンク３０への水素ガスの放出を許可する充填開始操作がなされると、充填が開始される（ステップＳ１）。これにより、蓄圧器１５に貯められていた水素ガスが、プレクーラ１８によって冷却された後、ガスタンク３０へと放出される。   First, when the filling operator connects the filling nozzle 12 and the receptacle 32 and performs a filling start operation for permitting the release of hydrogen gas from the gas filling device 2 to the gas tank 30, the filling is started. (Step S1). Thereby, the hydrogen gas stored in the pressure accumulator 15 is cooled by the precooler 18 and then released to the gas tank 30.

この充填の開始直後に、タンク圧力、タンク温度及びプレクーラ温度が読み込まれる。タンク圧力は、ガスタンク３０内の水素ガスの圧力であり、圧力センサ４２によって検出される。タンク温度は、ガスタンク３０内の水素ガスの温度であり、温度センサ４０によって検出される。タンク圧力及びタンク温度の検出信号は、制御装置４６に入力され、制御装置４６は、通信機４４を利用して、タンク圧力及びタンク温度の検出値をガス充填装置２に伝える。これにより、ガス充填装置２の制御装置２４は、充填開始直後のタンク圧力及びタンク温度を把握する。一方、プレクーラ温度は、プレクーラ１８での水素ガスの温度であり、温度センサＴによって検出される。プレクーラ温度の検出信号を直接入力される制御装置２４は、充填開始直後のプレクーラ温度を把握することになる。   Immediately after the start of this filling, the tank pressure, tank temperature and precooler temperature are read. The tank pressure is the pressure of hydrogen gas in the gas tank 30 and is detected by the pressure sensor 42. The tank temperature is the temperature of hydrogen gas in the gas tank 30 and is detected by the temperature sensor 40. The tank pressure and tank temperature detection signals are input to the control device 46, and the control device 46 transmits the detected values of the tank pressure and the tank temperature to the gas filling device 2 using the communication device 44. Thereby, the control apparatus 24 of the gas filling apparatus 2 grasps | ascertains the tank pressure and tank temperature immediately after a filling start. On the other hand, the precooler temperature is the temperature of the hydrogen gas in the precooler 18 and is detected by the temperature sensor T. The controller 24 to which the detection signal of the precooler temperature is directly input grasps the precooler temperature immediately after the start of filling.

この３つの情報を読み込んだ後、制御装置２４は、ＲＯＭ等に記憶した充填流量マップから充填流量を決定する（ステップＳ２）。充填流量マップの一例を図４に示すように、充填流量マップＭａは、縦軸をタンク圧力、横軸をタンク温度としたものであり、複数のプレクーラ温度（例えばＴ1，Ｔ2，Ｔ3であり、Ｔ1＜Ｔ2＜Ｔ3の関係があるとする。）ごとに設けられる。例えば、検出されたプレクーラ温度がＴ1、タンク圧力が４０ＭＰａ、タンク温度が０℃である場合、制御装置２４は、充填流量としてＤ４[ｍ3／ｍｉｎ]を選択し、決定する。 After reading these three pieces of information, the control device 24 determines the filling flow rate from the filling flow rate map stored in the ROM or the like (step S2). As shown in FIG. 4 as an example of the filling flow rate map, the filling flow rate map Ma has the tank pressure on the vertical axis and the tank temperature on the horizontal axis, and a plurality of precooler temperatures (for example, T 1 , T 2 , T 3). And there is a relationship of T 1 <T 2 <T 3 ). For example, when the detected precooler temperature is T 1 , the tank pressure is 40 MPa, and the tank temperature is 0 ° C., the control device 24 selects and determines D4 [m 3 / min] as the filling flow rate.

充填流量マップＭａにおける各充填流量は、タンク圧力、タンク温度及びプレクーラ温度の各条件下において、ガスタンク３０内に水素ガスを円滑に高速充填できる流量である。より詳細には、充填流量マップＭａにおける各充填流量は、上記３つの条件下において、ガスタンク３０内の温度が所定の上限値（例えば８５℃）に達しないようにできるだけ短時間でできるだけ多くの充填量（例えばフル充填量）を充填することが可能な流量である。なお、充填流量マップＭａでは、タンク圧力を１０Ｍｐａごとに、タンク温度を１０℃ごとに設定したが、もちろんこれらの幅は任意に設定することができる。また、プレクーラ温度についても、例えば２〜３℃、５℃又は１０℃ごとに任意に設定することができる。   Each filling flow rate in the filling flow map Ma is a flow rate at which hydrogen gas can be smoothly and rapidly filled into the gas tank 30 under the conditions of tank pressure, tank temperature, and precooler temperature. More specifically, each of the filling flow rates in the filling flow rate map Ma is filled as much as possible in the shortest possible time so that the temperature in the gas tank 30 does not reach a predetermined upper limit value (for example, 85 ° C.) under the above three conditions. This is the flow rate at which an amount (for example, a full filling amount) can be filled. In the filling flow rate map Ma, the tank pressure is set every 10 Mpa and the tank temperature is set every 10 ° C. Of course, these widths can be arbitrarily set. Further, the precooler temperature can be arbitrarily set, for example, every 2-3 ° C, 5 ° C, or 10 ° C.

ここで、充填流量マップＭａにおける充填流量の値の大小関係について、二つ説明する。
第１に、タンク圧力及びタンク温度が同じ条件であれば、プレクーラ温度が高いほど充填流量の値が小さくなる。例えば、タンク圧力が４０ＭＰａ、タンク温度が０℃である場合、プレクーラ温度Ｔ2での充填流量は、プレクーラ温度Ｔ1での充填流量Ｄ４よりも小さい。このような減少させた充填流量を用いることで、連続充填の影響でプレクーラ温度が上昇している場合にも、ガスタンク３０内の温度が上限値に達しないように、できるだけ短時間で充填することが可能となる。 Here, two magnitude relationships between the values of the filling flow rate in the filling flow rate map Ma will be described.
First, if the tank pressure and the tank temperature are the same, the value of the filling flow rate decreases as the precooler temperature increases. For example, when the tank pressure is 40 MPa and the tank temperature is 0 ° C., the filling flow rate at the precooler temperature T 2 is smaller than the filling flow rate D4 at the precooler temperature T 1 . By using such a reduced filling flow rate, even when the precooler temperature rises due to the effect of continuous filling, filling is performed in as short a time as possible so that the temperature in the gas tank 30 does not reach the upper limit value. Is possible.

第２に、プレクーラ温度が同じ条件であれば、タンク圧力が大きいほど充填流量を大きくすることが可能である。またこの条件では、タンク温度が小さいほど充填流量を大きくすることが可能である。例えば、プレクーラ温度Ｔ1においては、充填流量マップＭａにおける充填流量Ａ１〜Ｈ８のうち、充填流量Ｈ１（タンク圧力８０ＭＰａ，タンク温度−３０℃）が最も大きく、充填流量Ａ８（タンク圧力１０ＭＰａ，タンク温度４０℃）が最も小さくなる。このように、タンク圧力が低い場合やタンク温度が高い場合に、減少させた充填流量を用いることで、ガスタンク３０内の温度が上限値に達しないように、できるだけ短時間で充填することが可能となる。 Second, if the precooler temperature is the same, the filling flow rate can be increased as the tank pressure increases. Also, under this condition, it is possible to increase the filling flow rate as the tank temperature decreases. For example, at the precooler temperature T 1 , the filling flow rate H1 (tank pressure 80 MPa, tank temperature −30 ° C.) is the largest among the filling flow rates A1 to H8 in the filling flow map Ma, and the filling flow rate A8 (tank pressure 10 MPa, tank temperature). 40 ° C) is the smallest. As described above, when the tank pressure is low or the tank temperature is high, by using the reduced filling flow rate, the gas tank 30 can be filled in as short a time as possible so as not to reach the upper limit value. It becomes.

ステップＳ３では、ステップＳ２で決定した充填流量となるように、制御装置２４がガス充填装置２を制御する。具体的には、制御装置２４は、流量計１７の計測結果を見ながら、決定した充填流量となるように流量制御弁１６の開度を制御する。これにより、タンク圧力、タンク温度及びプレクーラ温度の各条件に応じた充填流量にて、水素ガスがガスタンク３０に充填される。   In step S3, the control device 24 controls the gas filling device 2 so that the filling flow rate determined in step S2 is obtained. Specifically, the control device 24 controls the opening degree of the flow control valve 16 so that the determined filling flow rate is obtained while observing the measurement result of the flow meter 17. As a result, the hydrogen gas is filled into the gas tank 30 at a filling flow rate corresponding to each condition of the tank pressure, the tank temperature, and the precooler temperature.

この充填中、ガス充填装置２の表示装置２２及び車両３の表示装置４８の少なくとも一つには、ステップＳ２で決定した充填流量にて充填されている旨が表示される。すなわち、充填作業者は、ガス充填システム１における表示装置２２，４８の少なくとも一つの表示により、プレクーラ温度を含む諸条件に基づいて充填流量が制御されている旨を確認することができるようになっている。   During the filling, at least one of the display device 22 of the gas filling device 2 and the display device 48 of the vehicle 3 displays that filling is performed at the filling flow rate determined in step S2. That is, the filling operator can confirm that the filling flow rate is controlled based on various conditions including the precooler temperature, based on at least one display of the display devices 22 and 48 in the gas filling system 1. ing.

その後、所定の充填量（充填作業者が指定した充填量又はフル充填量）がガスタンク３０に充填されると、ガス充填装置２からの水素ガスの供給が停止し、充填が終了する（ステップＳ４）。なお、充填終了後にも又は充填終了後にのみ、表示装置２２，４８の少なくとも一つに、上記同様の表示、例えばプレクーラ温度を含む諸条件に基づいて充填流量が制御された旨の表示を出すようにしてもよい。   Thereafter, when the gas tank 30 is filled with a predetermined filling amount (a filling amount designated by the filling operator or a full filling amount), the supply of hydrogen gas from the gas filling device 2 is stopped and the filling is completed (step S4). ). In addition, only after the filling is completed or only after the filling is finished, a display similar to the above, for example, a display that the filling flow rate is controlled based on various conditions including the precooler temperature is displayed on at least one of the display devices 22 and 48. It may be.

以上説明した本実施形態のガス充填システム１によれば、タンク圧力、タンク温度及びプレクーラ温度に応じた流量で水素ガスをガスタンク３０に充填することができる。特に、プレクーラの能力によっては冷却後の水素ガス温度が変動する場合があるが、本実施形態によれば、プレクーラ温度を検出し、それに応じた充填流量に制御することができる。このため、プレクーラ１８の冷却能力に応じた最適な充填が可能となり、ガスタンク３０内を安定した状態に保ちつつ、所定の充填量をできるだけ短時間で充填することができる。   According to the gas filling system 1 of the present embodiment described above, hydrogen gas can be filled into the gas tank 30 at a flow rate corresponding to the tank pressure, the tank temperature, and the precooler temperature. In particular, the hydrogen gas temperature after cooling may fluctuate depending on the capability of the precooler. However, according to the present embodiment, the precooler temperature can be detected and the charging flow rate can be controlled accordingly. For this reason, optimal filling according to the cooling capacity of the precooler 18 is possible, and a predetermined filling amount can be filled in as short a time as possible while keeping the inside of the gas tank 30 in a stable state.

例えば、上記したように、プレクーラ温度が上昇するにしたがって充填流量を減少させるように制御することで、ガスタンク３０内の上限温度を超えない円滑な高速充填を確保することができる。この効果を違う観点で換言すると、プレクーラ１８にて適正に冷却できていなくとも、充填を中止又は停止する必要が無いため、充填作業者又はドライバーを待たせなくて済む。また、複数の車両３に対する連続充填が可能となる。一方で、比較的低いプレクーラ温度の場合には、比較的大きい充填流量とすることで、ガスタンク３０内の上限温度を超えない円滑な充填を、より短時間で行うことができる。   For example, as described above, smooth high-speed filling that does not exceed the upper limit temperature in the gas tank 30 can be ensured by controlling the filling flow rate to decrease as the precooler temperature rises. In other words, this effect does not have to wait for the filling operator or the driver because it is not necessary to stop or stop the filling even if the precooler 18 is not properly cooled. Moreover, the continuous filling with respect to the some vehicle 3 is attained. On the other hand, in the case of a relatively low precooler temperature, smooth filling without exceeding the upper limit temperature in the gas tank 30 can be performed in a shorter time by setting a relatively large filling flow rate.

また、充填流量を決定するのに、タンク圧力及びタンク温度というガスタンク３０内の情報を実際に取得しているので、これらを推定する場合に比べて、より最適な充填流量を決定することができる。なお、他の実施態様では、タンク圧力及びタンク温度の一方又はいずれも考慮せずに、プレクーラ温度に応じた充填流量を決定し、制御するようにしてもよい。   Further, since the information in the gas tank 30 such as the tank pressure and the tank temperature is actually acquired to determine the filling flow rate, a more optimal filling flow rate can be determined as compared with the case where these are estimated. . In another embodiment, the filling flow rate according to the precooler temperature may be determined and controlled without considering one or both of the tank pressure and the tank temperature.

＜変形例＞
次に、本実施形態のガス充填システム１のいくつかの変形例について説明する。なお、各変形例は単独でも本実施形態に適用することができるが、他の変形例と組み合わせても適用することができる。 <Modification>
Next, some modified examples of the gas filling system 1 of the present embodiment will be described. Each modification can be applied to the present embodiment alone, but can also be applied in combination with other modifications.

第１の変形例では、充填流量を決定する際に、タンク圧力及びタンク温度を推定するようにしてもよい。この場合、ガス充填装置２側の機器を利用して推定することができる。例えば、タンク圧力については、圧力センサをガス充填装置２のガス流路１３に設け、この圧力センサによる充填開始直後の検出結果から推定することができる。また、タンク温度については、外気温センサ２３による充填開始直後の検出結果から推定することができる。このような推定を用いる方法は、ガス充填装置２と車両３とが通信手段（上記の通信機２１，４４）を具備しない非通信の場合に有用となる。   In the first modification, the tank pressure and the tank temperature may be estimated when the filling flow rate is determined. In this case, it can estimate using the apparatus of the gas filling apparatus 2 side. For example, the tank pressure can be estimated from a detection result immediately after the start of filling by the pressure sensor provided in the gas flow path 13 of the gas filling device 2. The tank temperature can be estimated from the detection result immediately after the start of filling by the outside air temperature sensor 23. The method using such estimation is useful when the gas filling device 2 and the vehicle 3 are not communicating without the communication means (the communication devices 21 and 44 described above).

第２の変形例では、プレクーラ温度を検出する温度センサＴの位置を変更してもよい。プレクーラ１８を通った冷却後の水素ガス温度に応じて充填流量を最適化するには、温度センサＴはプレクーラ１８とガスタンク３０の上流側との間の水素ガス温度を検出できればよい。したがって、温度センサＴは、車両３側のレセプタクル３２又は充填管路３４に設けられてもよく、ガス充填装置２からガスタンク３に向けて放出された後の水素ガス温度を検出してもよい。また別の態様では、温度センサＴは、充填ノズル１２に設けられてもよい、充填ノズル１２での水素ガス温度を検出してもよい。   In the second modification, the position of the temperature sensor T that detects the precooler temperature may be changed. In order to optimize the filling flow rate according to the temperature of the hydrogen gas after cooling through the precooler 18, the temperature sensor T only needs to be able to detect the hydrogen gas temperature between the precooler 18 and the upstream side of the gas tank 30. Therefore, the temperature sensor T may be provided in the receptacle 32 or the filling pipeline 34 on the vehicle 3 side, and may detect the hydrogen gas temperature after being released from the gas filling device 2 toward the gas tank 3. In another aspect, the temperature sensor T may detect the hydrogen gas temperature at the filling nozzle 12, which may be provided in the filling nozzle 12.

このような位置における温度センサＴの検出によれば、冷却された水素ガスの温度の検出値に対して、ガス充填装置２内の外乱の影響を考慮しなくて済む。換言すると、プレクーラ１８と充填ノズル１２との距離が遠い場合、プレクーラ１８で冷却された水素ガスは、ガス流路１３の配管で受熱するなどの影響で、充填ノズル１２での温度がプレクーラ１８の直下での温度よりも上がり得る。この点、充填ノズル１２以降の位置で水素ガス温度を検出するのであれば、このような影響を回避することができ、ガスタンク３０内の状態に最も影響する充填直前の水素ガス温度を検出することができる。したがって、充填流量をより精度良く制御することが可能となる。   According to the detection of the temperature sensor T at such a position, it is not necessary to consider the influence of disturbance in the gas filling device 2 on the detected value of the temperature of the cooled hydrogen gas. In other words, when the distance between the precooler 18 and the filling nozzle 12 is long, the hydrogen gas cooled by the precooler 18 receives the heat in the piping of the gas flow path 13, and the temperature at the filling nozzle 12 becomes lower than that of the precooler 18. Can rise above the immediate temperature. In this regard, if the hydrogen gas temperature is detected at a position after the filling nozzle 12, such an influence can be avoided, and the hydrogen gas temperature immediately before filling that most affects the state in the gas tank 30 is detected. Can do. Therefore, it is possible to control the filling flow rate with higher accuracy.

第３の変形例では、ガスタンク３０の数を複数にしてもよい。車両３に複数のガスタンクを搭載した場合には、その搭載位置の違いにより放熱率が異なったり、また、燃料電池への供給の仕方によっては各ガスタンクからの放出量も異なる。よって、ガスタンク３０が複数ある場合、複数のガスタンクのうちタンク温度が最も大きいガスタンク又はタンク圧力が最も小さいガスタンクの情報（タンク温度及びタンク圧力）とプレクーラ温度に基づいて、充填流量マップＭａから充填流量を決定するとよい。これにより、全てのガスタンクについて、上限温度に達するのを抑制しながら、短時間で所定の充填量を充填することができる。   In the third modification, the number of gas tanks 30 may be plural. When a plurality of gas tanks are mounted on the vehicle 3, the heat release rate varies depending on the mounting position, and the amount of discharge from each gas tank varies depending on the manner of supply to the fuel cell. Therefore, when there are a plurality of gas tanks 30, the filling flow rate map Ma is used to fill the flow rate based on the information (tank temperature and tank pressure) of the gas tank having the highest tank temperature or the gas tank having the lowest tank pressure and the precooler temperature. It is good to decide. Thereby, it is possible to fill a predetermined filling amount in a short time while suppressing reaching the upper limit temperature for all the gas tanks.

なお、第３の変形例の場合、各ガスタンクのタンク温度及びタンク圧力については、上記した温度センサ４０及び圧力センサ４２をガスタンクごとに設けることで取得することもできるし、あるいは計一つの温度センサ４０及び計一つの圧力センサ４２により全てのガスタンクについて取得することもできる。また、第２の変形例にて説明したように、各ガスタンクのタンク温度及びタンク圧力を推定することで取得することもできる。   In the case of the third modification, the tank temperature and tank pressure of each gas tank can be obtained by providing the temperature sensor 40 and the pressure sensor 42 for each gas tank, or a total of one temperature sensor. 40 and a single pressure sensor 42 can also be obtained for all gas tanks. Further, as described in the second modification, it can also be obtained by estimating the tank temperature and tank pressure of each gas tank.

本発明のガス充填システム１は、水素ガスのみならず、充填時に温度上昇が起きるガスに適用することができる。また、車両３に限らず、航空機、船舶、ロボットなど、外部からのガスの充填先としてガスタンクを搭載した移動体に適用することができる。   The gas filling system 1 of the present invention can be applied not only to hydrogen gas but also to gas that causes a temperature rise during filling. Further, the present invention can be applied not only to the vehicle 3 but also to a moving body equipped with a gas tank as a gas filling destination such as an aircraft, a ship, and a robot.
