Description

수소충전장치의 교정방법 {collection method for a hydrogen gas filling apparatus}Calibration method of hydrogen filling apparatus {collection method for a hydrogen gas filling apparatus}

본 발명은 수소 자동차 등에 수소를 충전하는 설비인 수소 스테이션에서 이용되는 수소충전장치에 관한 것으로, 그 수소충전장치를 교정하는 기술에 관한 것이다.The present invention relates to a hydrogen filling device used in a hydrogen station, which is a facility for recharging hydrogen in a hydrogen vehicle, etc., and relates to a technology for calibrating the hydrogen filling device.

근년에 연료전지를 탑재한 차량(연료전지 자동차: FCV)의 개발·보급에 따라 수소 스테이션의 설치 개소를 증가하는 것이 중요시 되고 있다. 수소 스테이션에는 수소충전장치가 설치되어 있어 수소충전장치에 의해 수소 스테이션에 도착한 상기 차량의 차량 탑재 탱크 내에 소정의 압력으로 수소를 충전하고 있다. 그리고, 차량 탑재 탱크 내의 수소 충전을 안전하고 정확하게 실시하기 위해서 수소충전장치를 교정하는 작업이 정기적으로 실시되고 있다. 이러한 교정작업에서는, 예를 들어 수소 충전 전후에서의 교정장치의 중량을 계측하고, 그 차이로부터 충전량을 결정하는 타입의 교정장치를 이용하여 실시된다. 그리고, 교정장치에 의해 계측된 실제의 수소충전량과, 수소충전장치가 계량한 충전 수소량과 비교함으로써 해당 수소충전장치의 교정이 실시된다. 혹은, 수소충전계통에 수소충전장치의 교정을 위한 수소 유량 계측장치를 설치하여, 연료전지 자동차에 수소를 충전하면서 수소충전계통에 개장된 수소 유량 계측장치(기준 유량계)로 연료전지 자동차에 실제로 충전된 수소량을 계측하고, 수소충전장치가 계량한 충전 수소량과 비교하여 교정이 이루어지는 경우가 있다. 현행의 수소충전에 관한 가이드 라인에 의하면(일본에서의 규정) 상술한 바와 같은 수소충전장치의 교정에서는 "4kg의 수소의 충전을 1회, 1kg의 수소의 충전을 3회" 실시하는 것이 정해져 있다. 이러한 가이드 라인에 따르면 단일 수소충전장치(40)의 교정에서는 최저 4회(4kg을 1회, 1kg을 3회)의 수소충전을 실시할 필요가 있다. 그러나, 교정 시에는 연료전지 자동차의 차량 탑재 탱크 내의 압력이 소정의 초기 압력이 된 상태(이른바 "비어있음"이 된 상태)에서 수소를 충전할 필요가 있다. 그 때문에 교정 시에는 연료전지 자동차에 소정량의 수소를 충전한 후, 수소를 충전한 연료전지 자동차를 도 8에서 화살표 R로 나타내는 것처럼 주행시켜서 차량 탑재 탱크내의 수소를 소비시켜 차량 탑재 탱크 내의 압력이 소정의 초기 압력으로 저감될 때까지(이른바 "비어있음"이 될 때까지) 교정작업을 중단할 필요가 있다. 또한, 충전호스, 부호 MA는 수소유량 계측장치(M) 측(마스터 미터 측)의 충전노즐, 부호 SA는 차량(S) 측의 리셉터클을 나타내고 있다. 혹은 상술한 수소의 유량 계측장치(M)(기준 유량계)에서 연료전지 자동차(S)에 실제로 충전된 수소량을 계측하는 교정을 실시하는 경우에는 1대의 수소충전장치를 교정하는 데에, 도 9에서 나타내는 것과 같이 차량 탑재 탱크 내의 압력이 소정의 초기 압력이 된 상태(이른바 "비어있음"이 된 상태)의 연료전기 자동차(S)(FCV)를 미리 복수 대(예를 들어 4대) 준비할 필요가 있다. 그러나, 차량 탑재 탱크 내의 압력이 소정의 초기 압력이 될 때까지(이른바 "비어있음"이 될 때까지) 연료전지 자동차를 주행시키는 경우(도 8)에는 교정을 중단하고 대기하는 시간이 장시간이 되므로 1대의 수소충전장치의 교정에 많은 시간을 소비하게 된다. 한편, 교정작업을 실시하기 위해 복수 대(예를 들어 4대)의 연료전지 자동차를 준비하는 것이라면 교정작업의 준비에 엄청난 노력과 비용이 필요하게 된다.In recent years, with the development and popularization of vehicles equipped with fuel cells (fuel cell vehicles: FCVs), it has become important to increase the number of installation locations of hydrogen stations. A hydrogen filling device is installed in the hydrogen station, and hydrogen is charged at a predetermined pressure in a vehicle-mounted tank of the vehicle arriving at the hydrogen station by the hydrogen filling device. In addition, in order to safely and accurately charge hydrogen in a vehicle-mounted tank, calibrating a hydrogen filling device is regularly performed. This calibration work is carried out using, for example, a calibration device of the type that measures the weight of the calibration device before and after charging with hydrogen, and determines the filling amount from the difference. Then, the hydrogen filling device is calibrated by comparing the actual hydrogen charge amount measured by the calibration device with the charged hydrogen amount measured by the hydrogen filling device. Alternatively, a hydrogen flow measuring device for calibrating the hydrogen charging device is installed in the hydrogen charging system, and the fuel cell vehicle is actually charged with the hydrogen flow measuring device (reference flow meter) installed in the hydrogen charging system while charging hydrogen in the fuel cell vehicle. There is a case in which the amount of hydrogen stored is measured, and correction is made by comparing it with the amount of charged hydrogen measured by the hydrogen charging device. According to the current hydrogen filling guidelines (regulations in Japan), it is stipulated that "4 kg of hydrogen is filled once and 1 kg of hydrogen is filled three times" in the calibration of the hydrogen filling equipment as described above. . According to these guidelines, it is necessary to perform hydrogen charging at least 4 times (4 kg once, 1 kg 3 times) in calibration of a single hydrogen charging device 40. However, during calibration, it is necessary to charge hydrogen in a state where the pressure in the vehicle-mounted tank of the fuel cell vehicle reaches a predetermined initial pressure (a so-called "empty" state). Therefore, at the time of calibration, after charging a predetermined amount of hydrogen into the fuel cell vehicle, the fuel cell vehicle filled with hydrogen is driven as indicated by the arrow R in FIG. It is necessary to stop the calibration operation until it has reduced to a certain initial pressure (so-called "empty"). Further, the charging hose, symbol MA, denotes a charging nozzle on the hydrogen flow measuring device M side (master meter side), and symbol SA denotes a receptacle on the vehicle S side. Alternatively, in the case of performing calibration for measuring the amount of hydrogen actually charged in the fuel cell vehicle S with the aforementioned hydrogen flow rate measuring device M (reference flow meter), in calibrating one hydrogen charging device, FIG. 9 As shown in , a plurality of fuel electric vehicles (S) (FCV) in a state where the pressure in the vehicle-mounted tank has reached a predetermined initial pressure (a so-called "empty" state) are prepared in advance (for example, 4 units). There is a need. However, when the fuel cell vehicle is driven until the pressure in the vehicle-mounted tank reaches a predetermined initial pressure (so-called "empty") (FIG. 8), the waiting time after stopping the calibration becomes long. It takes a lot of time to calibrate one hydrogen charging device. On the other hand, if a plurality of (for example, four) fuel cell vehicles are to be prepared for corrective work, great efforts and costs are required to prepare for corrective work.

The purpose is to provide a calibration method for a hydrogen charging device without

A process of connecting the charging nozzle 41 of the hydrogen charging device 40 to be calibrated to the receptacle 6 of the calibrating device 100 having The amount of hydrogen charged in the charging tank 2 of the calibration device 100 is determined based on the filling process and the difference between the weight of the measuring housing 1 before charging with hydrogen and the weight of the measuring housing 1 after charging with hydrogen. and a step of releasing the hydrogen charged in the charging tank 2 through the exhaust gas mechanism 11 installed in the calibration device 100. Here, the timing for executing the step of determining the amount of hydrogen is not limited between the step of determining the amount of hydrogen and the step of releasing hydrogen. The timing of executing the process of determining the amount of hydrogen can be executed at any timing as long as the process of filling the hydrogen gas is completed. In the calibration method of the present invention, the calibration device 100 is installed in a vehicle (PS: calibration vehicle), and the vehicle PS in which the calibration device 100 is installed is driven by a plurality of types of fuel including hydrogen. It is a vehicle, and an opening/closing valve 33 is provided in a path 32 that communicates the charging tank 2 of the calibration device 100 and the fuel storage device of the vehicle, and the vehicle PS stops to perform the calibration work. It is preferable to have a process of closing the on-off valve 33 in the case of carrying out, and opening the on-off valve 33 when the vehicle PS is running. In the present invention, the calibration device 100 includes a receptacle 6 that can be connected to and detached from the charging nozzle 41 at the tip of the charging hose 42 of the hydrogen charging device 40, and the information in the charging tank 2 It is provided with a signal transmission means 18 for transmitting to the hydrogen charging device 40, and in the process of filling the charging tank 2 with hydrogen gas, the information in the charging tank 2 is transmitted to the hydrogen charging device 40. It is desirable to convey

상술의 구성을 구비하는 본 발명에 의하면 교정완료 후 배기가스 기구(11)의 도시하지 않은 개방/폐쇄 기구를 조작함으로써 충전탱크(2) 내에 충전된 수소는 배기가스 기구(11)를 통해 교정 장치(100) 밖으로 개방된다. 배기가스 기구(11)를 통해 충전된 수소를 교정장치(100) 밖으로 개방하는 시간은 수소가 충전된 연료전지 자동차를 주행시켜서 충전탱크(2) 내의 압력을 소정의 초기압력까지 저하되는 데에 소요되는 시간에 비해 훨씬 단시간이다. 그 때문에, 차량 탑재 탱크의 압력이 소정의 초기압력으로 저하될 때까지 연료전지 자동차를 주행시켜서 교정을 대기할 필요가 없고, 복수의 연료전지 자동차(FCV)를 미리 준비할 필요도 없다. 그 결과, 단일의 수소충전장치(40)의 교정작업에 소요되는 시간, 노력, 비용이 대폭적으로 단축된다. 그리고 본 발명의 교정방법에 의하면 수소충전 전 계측하우징(1)의 중량과 수소충전 후 계측하우징(1)의 중량과의 차이에 근거하여 충전탱크(2)에 충전된 수소의 양을 정확하게 결정할 수 있으므로 당해 결정된 수소량과 수소충전장치(40)내의 유량계에 의해 계량된 수소충전량을 비교함으로써 교정작업의 대상이 되고 있는 수소충전장치(40)의 유량계의 정확도가 요구되는 수준에 이르고 있는가 아닌가를 정확하고 쉽게 확인할 수 있다. 또 본 발명에 있어서, 교정장치(100)를 차량(PS)에 설치 혹은 탑재하는 경우에 당해 차량(PS)이 바이퓨얼 차량이라면 교정장치(100) 내의 충전탱크(2)에 충전한 수소를 당해 차량(PS)의 연료로 소비할 수 있다. 또한, 본 발명에 있어서, 교정시에 교정장치의 충전탱크 내부에 설치된 계측장치(압력센서, 온도센서)에 의해 충전에 필요한 정보(압력 정보, 온도 정보)를 계측하고, 그 정보는 신호전달수단(18)을 통해 확실하게 충전장치(40)에 송신(통신)하면, 교정시에 있어서도 이른바 "통신충전"을 실행하여 실제의 연료전지 자동차(FCV)에 충전하는 것과 마찬가지의 높은 압력까지 안전하고 정확한 수소충전을 실행할 수 있다.According to the present invention having the above configuration, after calibration is completed, by operating an open/close mechanism (not shown) of the exhaust gas mechanism 11, the hydrogen charged in the charging tank 2 passes through the exhaust gas mechanism 11 to the calibration device. (100) is open to the outside. The time to open the hydrogen charged through the exhaust gas mechanism 11 to the outside of the calibration device 100 is required to lower the pressure in the charging tank 2 to a predetermined initial pressure by driving the fuel cell vehicle filled with hydrogen. It's a lot shorter than the time it takes. Therefore, there is no need to wait for calibration by driving the fuel cell vehicle until the pressure in the vehicle-mounted tank drops to a predetermined initial pressure, and there is no need to prepare a plurality of fuel cell vehicles (FCVs) in advance. As a result, the time, effort, and cost required for calibrating the single hydrogen charging device 40 are greatly reduced. In addition, according to the calibration method of the present invention, the amount of hydrogen charged in the charging tank 2 can be accurately determined based on the difference between the weight of the measuring housing 1 before charging with hydrogen and the weight of the measuring housing 1 after charging with hydrogen. Therefore, by comparing the determined amount of hydrogen with the hydrogen charge amount measured by the flow meter in the hydrogen charging device 40, it is accurately checked whether the accuracy of the flow meter of the hydrogen charging device 40, which is the target of calibration, reaches the required level. and can be easily verified. In the present invention, when the calibration device 100 is installed or mounted on the vehicle PS, if the vehicle PS is a bi-fuel vehicle, the hydrogen charged in the charging tank 2 in the calibration device 100 is It can be consumed as fuel for the vehicle PS. In addition, in the present invention, information (pressure information, temperature information) necessary for charging is measured by a measuring device (pressure sensor, temperature sensor) installed inside the filling tank of the calibration device during calibration, and the information is a signal transmission means If it is reliably transmitted (communicated) to the charging device 40 through (18), so-called "communication charging" is executed even during calibration, and it is safe to a high pressure equivalent to charging an actual fuel cell vehicle (FCV). Accurate hydrogen filling can be performed.

Reference numeral 2A denotes a charging gas inlet in the charging tank 2, and reference numeral 9 is a check valve for preventing reverse flow of hydrogen gas supplied to the instrument housing 1 side. A dry gas pipe 4 is detachably installed on the side surface of the instrumentation housing 1 (left side in FIG. 1), and dry gas is supplied into the instrumentation housing 1 from a supply source (not shown). A dew-point meter 5 is detachably installed on the outer surface of the measuring housing 1, and humidity is controlled within the measuring housing 1 based on the measurement result of the dew-point meter 5. For example, when hydrogen gas is supplied when the dew point temperature of the dew point meter 5 reaches a predetermined temperature, the amount of condensation generated in devices such as the charging tank 2, the charging gas supply pipe 7, and the receptacle 6 is reduced. It becomes less and the effect of condensation on weighing becomes sufficiently small.
