  Hereinafter, embodiments according to the present invention will be described with reference to the drawings.

  First, the configuration of the hydrogen station 1 according to the present embodiment will be described with reference to FIG. FIG. 1 is a diagram illustrating an example of a configuration of a hydrogen station 1 according to the present embodiment. The hydrogen station 1 according to the present embodiment is an off-site type hydrogen station where hydrogen is delivered by a trailer or the like.

  As shown in FIG. 1, the hydrogen station 1 includes a storage container RC, a compressor CP in which an inflow port is connected to a discharge port of the storage container RC and a pipe, and an inflow port is a discharge port and a pipe of the compressor CP. A connected pressure accumulator RS is provided. Furthermore, the hydrogen station 1 includes a dispenser DP whose inflow port is connected to the discharge port of the pressure accumulator RS by piping, and a pressure gauge PM connected to the discharge port of the pressure accumulator RS by piping. Further, the hydrogen station 1 includes a control device CD connected to the operation receiving unit OP, the pressure gauge PM by wiring and connected to the operation receiving unit OP by wiring, and a display device DIS connected to the control device CD by wiring. .

  Hydrogen is stored in the storage container RC. The pressure in the storage container RC is 45 MPa, for example.

  The compressor CP compresses the hydrogen supplied from the storage container RC.

  The pressure accumulator RS accumulates hydrogen compressed by the compressor. The pressure in the pressure accumulator RS is higher than the pressure in the storage container RC (for example, 80 MPa).

  The dispenser DP supplies the hydrogen supplied from the pressure accumulator RS to the vehicle FCV that uses hydrogen as fuel. Since the pressure (for example, 80 MPa) when discharged from the dispenser DP is higher than the pressure (for example, 70 MPa) of a fuel tank (not shown) of the vehicle FCV, hydrogen is discharged from the dispenser DP to the vehicle by this differential pressure. Supplied to FCV.

  The pressure gauge PM measures the pressure in the pressure accumulator RS and outputs a pressure signal indicating the measured pressure to the control unit CD.

  The operation reception unit OP receives an input from an operator (for example, a clerk of the hydrogen station 1).

  The control device CD controls the display device DIS.

  The display device DIS displays information according to the control of the control device CD.

  Subsequently, the operation of the hydrogen station 1 according to the present embodiment will be described. Hydrogen stored in the storage container RC is discharged to the compressor CP. The compressor CP compresses the hydrogen flowing in from the storage container RC and discharges the compressed hydrogen to the pressure accumulator RS. The pressure accumulator RS accumulates the hydrogen flowing in from the compressor CP. When a flow rate adjustment valve (not shown) mounted on the dispenser DP is opened, hydrogen is supplied from the pressure accumulator RS to the vehicle FCV through the dispenser DP.

  The pressure gauge PM measures the pressure in the pressure accumulator RS and outputs a pressure signal indicating the measured pressure to the control unit CD.

  The operation reception unit OP receives an input of the number of vehicles waiting for hydrogen filling at the hydrogen station 1 from the operator, and outputs a unit number signal indicating the received number to the control device CD.

  The control device uses the pressure signal input from the pressure gauge PM and the unit number signal input from the operation reception unit OP to wait for the standby start vehicle to start standby for hydrogen filling, The start time of filling or the pressure that can be filled in this waiting start vehicle is determined. The control device CD controls the display device DIS to display at least one piece of information indicating the determined waiting time, the start time of hydrogen filling, and the pressure that can be filled. As a result, for example, “current waiting time 10 minutes” or “current filling pressure 60 MPa” is displayed on the display device DIS.

  Next, the configuration of the control device CD according to the present embodiment will be described with reference to FIG. FIG. 2 is a diagram illustrating an example of the configuration of the control device CD according to the present embodiment. As illustrated in FIG. 2, the control device CD includes a storage unit 11, a RAM (Random Access Memory) 12, an input unit 13, an output unit 14, and a CPU 15. The components of these control devices CD are connected to each other by an internal bus.

  The storage unit 11 stores various programs that the CPU 15 reads and executes.

  The RAM 12 is a volatile memory that primarily stores data.

  The input unit 13 outputs the pressure signal input from the pressure gauge PM and the unit number signal input from the operation input unit X to the CPU 15.

  The output unit 14 outputs a signal indicating the hydrogen filling waiting time or the hydrogen filling start time determined by the CPU 15 to the display device DIS. Thereby, the display device DIS displays information indicating the waiting time of hydrogen filling or the start time of hydrogen filling.

  The CPU 15 functions as the determination unit 151 and the display control unit 152 by reading the program stored in the storage unit 11 into the RAM 12 and executing it.

  The determination unit 151 is a vehicle that uses hydrogen as fuel, and acquires the number of vehicles on standby for filling hydrogen from the operation reception unit OP via the input unit 13. The determination unit 151 determines the waiting time of the vehicle to start standby for hydrogen filling or the hydrogen filling start time, using the acquired number.

  More specifically, the determination unit 151 determines the total number of vehicles that are filling hydrogen by the dispenser DP, that is, one vehicle, and the number of vehicles that are on standby for filling hydrogen by the dispenser DP. To get. And the determination part 151 acquires the pressure in the pressure accumulator which accumulates hydrogen, and based on the acquired pressure in the pressure accumulator, the number of vehicles which can be filled with hydrogen within a specified time (for example, 5 minutes) is determined. decide.

  And the determination part 151 is filled with hydrogen to the pressure accumulator RS until the inside of the pressure accumulator RS becomes set pressure using the determined number of vehicles which can be filled, the acquired total number, and the hydrogen stored in the storage container. Is used to determine the waiting time of the vehicle to start waiting for filling hydrogen by the dispenser DP.

  Here, the waiting time is the time required from the start of standby of the vehicle FCV to the completion of filling of hydrogen into the vehicle FCV, or the time required from the start of standby of the vehicle FCV to the start of filling of hydrogen into the vehicle FCV. is there.

  Next, a calculation example of the time T required from the start of standby of the vehicle FCV to the start of filling of hydrogen into the vehicle FCV will be described below.

  Here, since the residual pressure of a vehicle waiting for hydrogen filling (hereinafter referred to as a “waiting vehicle”) is unknown, a specified time (for example, including work, payment time, etc.) for all waiting vehicles is included. 5 minutes). Further, the pressure accumulator RS has a one-bank configuration. Further, it is assumed that the delivery of hydrogen to the hydrogen station 1 is executed without delay, and the residual pressure Pb of the storage container RC is always equal to or higher than the lower limit pressure PbL of the storage container RC.

  In addition, when the residual pressure of the pressure accumulator RS falls to the lower limit pressure PaL of the pressure accumulator RS required for charging hydrogen for a specified time (for example, 5 minutes), the pressure accumulator RS is filled with hydrogen from the storage container RC. Start. The filling of hydrogen from the storage container RC to the pressure accumulator RS continues until the pressure accumulator RS reaches a set pressure (for example, 80 MPa). One supply nozzle is connected to the dispenser DP, and the vehicle is sequentially filled with hydrogen from the same dispenser DP.

  Assume that the specified time is Td, the residual pressure of the pressure accumulator RS is Pa, and S is the total number of vehicles filled with hydrogen and the number of vehicles waiting for filling with hydrogen. Further, when the residual pressure Pa of the pressure accumulator RS is a set pressure (for example, 80 MPa), the number of vehicles that can be continuously charged with hydrogen in a specified time Td (for example, 5 minutes) per vehicle is C, and the residual pressure Pa of the pressure accumulator RS is In this case, the number of vehicles that can be continuously filled with hydrogen at a specified time Td per vehicle (hereinafter, the number of vehicles that can be filled) is F (Pa). However, the number of vehicles that can be filled is a function of the residual pressure Pa of the accumulator RS. When the residual pressure Pa of the accumulator RS is 80 MPa, the function F = C and the residual pressure Pa of the accumulator RS is equal to or lower than the lower limit pressure PaL. In this case, the function F = 0. Moreover, until the pressure in the pressure accumulator RS becomes a set pressure (for example, 80 MPa), the pressure accumulator RS is used until the pressure in the pressure accumulator RS becomes the set pressure (for example, 80 MPa) using hydrogen stored in the storage container RC. Let Tp be the time required for filling with hydrogen.

  Based on the premise described above, the time T required from the start of standby of the vehicle FCV to the start of filling of hydrogen into the vehicle FCV is expressed by the following equation (1) or equation (2).

(A) When S <F (Pa) T = Td × S (1)
(B) When F (Pa) × i ≦ S <F (Pa) × (i + 1) (i is a natural number)
T = Td × S + Tp × i (2)
As shown in the above formula (1), the determination unit 151 compares the total number S with the number of refillable vehicles F (Pa), and the total number S is smaller than the number of refillable vehicles F (Pa) (A) The time obtained by multiplying the specified time Td by the total number S is determined as the waiting time.

  As shown in the above formula (2), the determination unit 151 compares the total number S with the number of refillable vehicles F (Pa), and the total number S is equal to or more than i times the refillable number of vehicles F (Pa), and When the number of vehicles that can be filled F (Pa) is less than (i + 1) times (B), the waiting time is determined by adding i times the required filling time Tp to the time obtained by multiplying the specified time Td by the total number S. To do.

  Subsequently, a calculation example of the pressure that can be charged in the standby start vehicle that starts standby for hydrogen filling will be described below. As a premise, it is assumed that the control device CD stores in advance a table in which the relationship between the hydrogen pressure, the capacity, and the number of moles is defined. On that premise, when the pressure of the pressure accumulator RS is Pa and the capacity of the pressure accumulator is Va, the control device CD refers to the table to determine the mole number Na of hydrogen in the pressure accumulator. Further, it is assumed that the number of moles of hydrogen in the tank of the standby start vehicle is Nf. Therefore, the total number of moles Na of hydrogen in the pressure accumulator and the number of moles of hydrogen in the tank of the standby start vehicle is (Na + Nf). Assuming the tank capacity Vf of the standby start vehicle, the total capacity of the accumulator capacity Va and the standby start vehicle tank capacity Vf is (Va + Vf).

  The control device CD reads the pressure Pe corresponding to the set of the total number of moles (Na + Nf) and the total capacity (Va + Vf) from the table. The read pressure Pe is a pressure when the accumulator RS is connected to the tank of the standby start vehicle via the dispenser DP, and then the equilibrium state is reached.

  For example, the pressure that can be filled in the tank of the standby start vehicle in a specified time Td (for example, 5 minutes) is a pressure (Pe−Pd) that is smaller than the read pressure Pe by a preset pressure Pd. Therefore, for example, the control device CD sets a pressure (Pe−Pd) that is smaller than the read pressure Pe by a preset pressure Pd as a pressure that can be charged in the standby start vehicle that starts standby for hydrogen filling. The displayed information is displayed on the display device DIS.

  As described above, the control device CD according to the present embodiment acquires the number of vehicles on standby for charging hydrogen used as fuel, and uses the acquired number of vehicles to wait for hydrogen charging. A waiting time of the standby start vehicle to start, a start time of hydrogen filling at the start of standby, or a determination unit 151 that determines a pressure that can be charged to the standby start vehicle; a waiting time determined by the determination unit 151; a start time of hydrogen filling; Or the display control part 152 which controls the display apparatus DIS so that at least 1 information may be displayed among the information which shows the pressure which can be filled is provided.

  Therefore, since the control device CD according to the present embodiment can display information indicating the waiting time or the start time of hydrogen filling on the display device DIS, the customer who visits the hydrogen station 1 for filling with hydrogen waits for the waiting time. Can be grasped. As a result, the customer can wait for hydrogen filling when the waiting time is acceptable, or park the vehicle FCV at the hydrogen station 1 and do other work during the waiting time and return before the waiting time elapses. Can be. On the other hand, if the waiting time is not acceptable, the customer can visit the store again at another date and time or go to another hydrogen station.

  In addition, since the control device CD according to the present embodiment can display information indicating the pressure that can be filled in the standby start vehicle on the display device DIS, the customer who visits the hydrogen station 1 for filling with hydrogen It is possible to grasp the pressure that can be filled in the customer's vehicle. This allows the customer to wait for hydrogen filling if the fillable pressure is acceptable, or to visit the store again at another date or to another hydrogen station if the fillable pressure is unacceptable. it can. As a result, customer convenience can be improved.

  In addition, although the hydrogen station 1 of this embodiment demonstrated the off-site station, it is not restricted to this, The hydrogen station 1 may be an on-site station which produces | generates hydrogen from a raw material. In that case, in the hydrogen station 1, it is assumed that the raw materials (for example, natural gas, liquefied petroleum gas (LPG), etc.) are always sufficiently held, and the determination unit 151 waits according to the above (1) or (2). May be determined.

  In the hydrogen station 1 of the present embodiment, the operation reception unit OP receives the number of vehicles on standby, and the determination unit 151 acquires the number of vehicles on standby. However, the present invention is not limited to this. Absent. Instead, an infrared sensor is provided for each parking space in the hydrogen station, and when the infrared sensor detects the vehicle, the determination unit 151 increases the number of the waiting vehicles by 1, thereby increasing the number of the waiting vehicles. The number of units may be acquired.

  In the present embodiment, the determination unit 151 and the display control unit 152 are realized by reading and executing a program stored in advance in the storage unit 11 in the CPU 15, but this program is stored in a CD-ROM or the like. It may be realized by storing the program in a medium or distributing the program through a network and installing the program in the control device CD as appropriate. In addition, the determination unit 151 and the display control unit 152 appropriately store a memory, a hard disk or a storage medium such as a CD-R, a CD-RW, a DVD-RAM, a DVD-R, or the like, which is incorporated in or externally attached to the control device CD. It can be realized by using.
