[0006] Problem that the invention aims to solve

[0007] However, when hydrogen is produced under the above-mentioned conditions, the upper limit of the amount of fuel produced is the capacity of the accumulator that stores the fuel, and therefore the cost for producing hydrogen cannot necessarily be reduced sufficiently.

[0008] One embodiment of the present invention has been made in view of the above circumstances, and an object of the present invention is to provide a manufacturing plan generation system, a manufacturing plan generation method, and a manufacturing system capable of suppressing the manufacturing cost of fuel supplied to a vehicle.

[0009] Solutions for solving problems

[0010] In order to achieve the above-mentioned purpose, a manufacturing plan generation system involved in one embodiment of the present invention generates a manufacturing plan for vehicle fuel, and the manufacturing plan generation system comprises: a condition information acquisition unit, which acquires condition information, the condition information including information indicating the supplyable amount of fuel that can be supplied to a vehicle that can be supplied with the manufactured fuel; and a manufacturing plan generation unit, which generates a manufacturing plan including the manufacturing time and manufacturing amount of the fuel based on the condition information acquired by the condition information acquisition unit.

[0011] In a manufacturing plan generation system according to an embodiment of the present invention, a manufacturing plan is generated based on condition information including information indicating the available supply amount of fuel. Therefore, the generated manufacturing plan can be set as a manufacturing plan that takes supply to a vehicle into consideration, and as a result, the manufacturing cost of the fuel supplied to the vehicle can be suppressed.

[0012] The manufacturing plan generating unit may also set the upper limit amount of the fuel to be manufactured based on the condition information acquired by the condition information acquiring unit, and generate the manufacturing plan. According to this configuration, the upper limit amount of the fuel to be manufactured is set based on the condition information including information indicating the supplyable amount of the fuel, and the manufacturing plan is generated. As a result, the manufacturing cost of the fuel supplied to the vehicle can be more appropriately and reliably suppressed.

[0013] The condition information acquisition unit may also be configured to acquire condition information that also includes information indicating the storable amount of fuel related to a storage device capable of storing the manufactured fuel other than the vehicle. According to this configuration, the manufacturing plan can be configured to consider storage in the storage device in addition to supply to the vehicle, and as a result, the manufacturing cost of the fuel supplied to the vehicle can be further suppressed.

[0014] The manufacturing plan generating unit may acquire information indicating the manufacturing cost of the fuel at each time point and generate the manufacturing plan based on the manufacturing cost. According to this configuration, a manufacturing plan that suppresses the manufacturing cost of the fuel can be generated appropriately and reliably.

[0015] The fuel to be produced may be hydrogen, and the production cost of the fuel may include the price of electricity. According to this configuration, a production plan for hydrogen as a fuel can be appropriately and reliably generated.

[0016] The manufacturing plan generating system may further include a vehicle management unit that manages the availability of vehicles based on the supply of fuel to the vehicles generated based on the manufacturing plan generated by the manufacturing plan generating unit. According to this configuration, the vehicles can be appropriately managed based on the generated manufacturing plan.

[0017] The vehicle management unit may also be configured to determine whether there is an available vehicle based on the free capacity of the fuel tank of the vehicle corresponding to the supply of fuel to the vehicle based on the manufacturing plan generated by the manufacturing plan generation unit. According to this structure, the vehicle can be managed more appropriately.

[0018] The vehicle management unit may also be configured to add new restrictions on the supply of fuel to vehicles used by a specified user and instruct the manufacturing plan generation unit to generate a new manufacturing plan when it is determined that there are no available vehicles and the storage amount of the generated fuel does not satisfy the conditions related to the supply of the fuel to the vehicle used by the specified user. According to this structure, an appropriate manufacturing plan that also corresponds to the availability of the vehicle can be generated.

[0019] The vehicle may be a rental vehicle. According to this configuration, the manufacturing cost of the fuel provided to the rental vehicle can be suppressed more appropriately and more reliably.

[0020] The condition information acquisition unit may also be configured to acquire information indicating the free capacity of a fuel tank of the vehicle transmitted from the vehicle when the vehicle enters a preset parking space as information indicating the available supply amount of fuel that can be supplied to the vehicle. According to this configuration, information for generating a manufacturing plan can be appropriately and reliably acquired. As a result, the manufacturing cost of the fuel supplied to the vehicle can be more appropriately and reliably suppressed.

[0021] Alternatively, the condition information acquisition unit may acquire information indicating the fuel manufacturing capacity of a manufacturing device for manufacturing fuel for a vehicle, and the manufacturing plan generation unit may generate a manufacturing plan based on the information indicating the fuel manufacturing capacity of the manufacturing device acquired by the condition information acquisition unit. According to this configuration, an appropriate manufacturing plan that also corresponds to the fuel manufacturing capacity of the manufacturing device can be generated.

[0022] In addition, one embodiment of the present invention can be described as an invention of a manufacturing plan generation system as described above, and can also be described as an invention of a manufacturing plan generation method as described below. These inventions are substantially the same inventions with different categories and have the same functions and effects.

[0031] Below, with the attached Figure 1 The following describes the manufacturing plan generation system, the manufacturing plan generation method, and the manufacturing system according to the present invention in detail. In the description of the drawings, the same elements are denoted by the same reference numerals, and repeated descriptions are omitted.

[0032] exist Figure 1 The manufacturing plan generation system 10 involved in the present embodiment is shown in the figure. The manufacturing plan generation system 10 is a system (device) for generating a manufacturing plan for the fuel of a vehicle. In the present embodiment, the vehicle is an FC mobile body such as a fuel cell vehicle, and the fuel of the vehicle is hydrogen (H2). However, the manufacturing plan generation system 10 can also generate a manufacturing plan for a fuel other than hydrogen. The manufacturing plan of hydrogen includes the time of manufacturing hydrogen and the amount of hydrogen manufactured at each time. For example, the manufacturing plan of hydrogen represents the amount of hydrogen manufactured in units of 30 minutes. The manufacturing plan generation system 10 generates a manufacturing plan in a manner that satisfies the manufacturing conditions described later. In addition, the manufacturing plan generation system 10 generates a manufacturing plan by taking into account the manufacturing cost of hydrogen at each time of manufacturing hydrogen.

[0033] Specifically, the manufacturing plan generation system 10 is a PC (personal computer) or a server device, etc., which is a computer including hardware such as a CPU (Central Processing Unit) and a memory. The various functions of the manufacturing plan generation system 10 described below are exerted by operating these components using programs, etc. In addition, the manufacturing plan generation system 10 can be implemented by a single computer or a computer system composed of a plurality of computers connected to each other via a network. In addition, the manufacturing plan generation system 10 can also have a communication function for sending and receiving information with other devices as needed.

[0034] The manufacturing plan generation system 10 generates, for example, Figure 1The manufacturing plan of hydrogen produced in the facility 20 shown. The facility 20 includes a hydrogen station 30 and a standby place 40. The facility 20 is used to rent the FC mobile body 50 to the user. The manufacturing plan generation system 10 can also be set by an operator (business operator) who rents the FC mobile body 50. That is, the FC mobile body 50 is a rented vehicle.

[0035] The waiting place 40 is a place where the FC mobile body 50 can be parked. The FC mobile body 50 to be rented is parked at the waiting place 40, and the user can rent the FC mobile body 50 to be rented parked at the waiting place 40.

[0036] The hydrogen station 30 is a place (facility) for producing hydrogen as fuel for the FC mobile body 50 and filling (supplying) the produced hydrogen to the FC mobile body 50. The hydrogen station 30 is provided with a hydrogen production device 31 and a hydrogen supply device 32. The hydrogen supply device 32 includes a compressor 33, a pressure accumulator 34, and a distributor 35.

[0037] The hydrogen manufacturing device 31 is a device that performs water electrolysis to produce hydrogen. The hydrogen manufacturing device 31 produces hydrogen according to the production plan generated by the production plan generation system 10. For example, commercial electricity is used to produce hydrogen by the hydrogen manufacturing device 31. Figure 2 As shown in FIG. 1 , the price of commercial power (the price per unit of power) varies at each time. The numerical value of the power price is the numerical value (yen) shown on the left side of the graph. Therefore, the production cost of hydrogen varies depending on the time.

[0038] As the electric power used in the production of hydrogen by the hydrogen manufacturing device 31, electric power other than commercial electric power may be used instead of commercial electric power or in addition to commercial electric power. As the electric power other than commercial electric power, for example, electric power obtained by solar power generation or wind power generation performed by a self-provided device. These devices may also be set up in the land of the hydrogen manufacturing device 31 or in the adjacent land.

[0039] The hydrogen supply device 32 is a device for supplying hydrogen produced by the hydrogen manufacturing device 31 to the FC mobile body 50. The compressor 33 included in the hydrogen supply device 32 is a device for increasing the pressure of the hydrogen produced by the hydrogen manufacturing device 31. The accumulator 34 is a storage device for storing the hydrogen produced by the hydrogen manufacturing device 31. The accumulator 34 stores the hydrogen that has been pressurized by the compressor 33. The distributor 35 is a device for supplying the hydrogen to the FC mobile body 50 while controlling the flow rate and pressure of the hydrogen stored in the accumulator 34. The hydrogen manufacturing device 31, and the compressor 33, accumulator 34 and distributor 35 included in the hydrogen supply device 32 can use conventional devices. In addition, as a storage device for storing hydrogen, a device other than the accumulator 34 can also be used.

[0040] The FC mobile body 50 as a rental object parked at the waiting place 40 is filled with hydrogen in advance at the hydrogen station 30. In the present embodiment, the filling of hydrogen into the FC mobile body 50 is performed from the accumulator 34 via the dispenser 35. However, the filling of hydrogen into the FC mobile body 50 does not need to be performed from the accumulator 34, and may also be performed from the hydrogen manufacturing device 31 via the compressor 33 and the dispenser 35 in a manner that hydrogen is not stored in the accumulator 34 (such filling is called direct filling). The operation of filling the FC mobile body 50 with hydrogen is performed, for example, by an operator who leases the FC mobile body 50. The hydrogen station 30 and the waiting place 40 may be set at the same place or at different places. When the hydrogen station 30 and the waiting place 40 are set at different places, when the operation of filling the FC mobile body 50 with hydrogen is performed, the FC mobile body 50 moves to the hydrogen station 30.

[0041] The user can also bring the FC mobile body 50 whose hydrogen filling has decreased due to use after the rental into the waiting place 40, and transfer to another FC mobile body 50 that is parked at the waiting place 40 at that time and has been fully filled with hydrogen. By renting the FC mobile body 50 in this way, the FC mobile body 50 can be used without the user himself filling the FC mobile body 50. For example, the rental of the FC mobile body 50 is performed by a monthly fee including a usage-based fee.

[0042] The FC vehicles 50 to be rented may include a plurality of vehicle types of FC vehicles 50. For example, the vehicle types include ordinary passenger cars, buses, and trucks.

[0043] As will be described later, the manufacturing plan generating system 10 has a function of managing the FC moving body 50. In addition, the manufacturing plan generating system 10 does not necessarily need to be based on the above-mentioned facility 20 and business.

[0044] Manufacturing system 100 according to the present embodiment includes manufacturing plan creation system 10 and hydrogen manufacturing apparatus 31. In addition, manufacturing system 100 may include the above-mentioned configurations in addition to the above.

[0045] Next, the functions of the manufacturing plan generating system 10 according to the present embodiment will be described. Figure 1 As shown, the manufacturing plan generating system 10 is configured of a condition information acquiring unit 11 , a manufacturing plan generating unit 12 , and a vehicle managing unit 13 .

[0046] The condition information acquisition unit 11 is a functional unit that acquires condition information including information indicating the available supply amount of fuel that can be supplied to a vehicle that can be supplied with the manufactured fuel. The condition information acquisition unit 11 may also acquire condition information that also includes information indicating the available storage amount of fuel related to a storage device other than the vehicle that can store the manufactured fuel. The condition information acquisition unit 11 may also acquire information indicating the free capacity of a fuel tank of the vehicle, which is transmitted from the vehicle when the vehicle enters a preset parking space, as information indicating the available supply amount of fuel that can be supplied to the vehicle. The condition information acquisition unit 11 may also acquire information indicating the fuel manufacturing capacity of a manufacturing device for manufacturing fuel for the vehicle.

[0047] The condition information is information indicating the conditions that become restrictions when hydrogen is manufactured by the hydrogen manufacturing device 31. The hydrogen manufactured by the hydrogen manufacturing device 31 needs to be stored in a certain device. Therefore, the amount of hydrogen manufactured that can be stored becomes one of the above conditions. In the present embodiment, the manufactured hydrogen can also be stored (filled) in the fuel tank possessed by the FC mobile body 50 via the accumulator 34. The capacity of the accumulator 34 is a capacity corresponding to the scale of the hydrogen station, for example, about 700Nm3. Regarding the capacity of the fuel tank possessed by the FC mobile body 50, for example, if it is an ordinary passenger car, it is about 60Nm3, and if it is a bus, it is about 270Nm3. The condition information acquisition unit 11 acquires information indicating the supplyable amount (fillable amount) of hydrogen that can be supplied to the FC mobile body 50 parked at the waiting place 40 as condition information.

[0048] For the FC mobile bodies 50 that can be parked at the waiting place 40, that is, the FC mobile bodies 50 that become the rental objects, a vehicle number as information for identifying the FC mobile body 50 is pre-set for each FC mobile body 50. In the manufacturing plan generation system 10, it can also be set to be able to determine the vehicle type based on the vehicle number. A system that can detect the free capacity (for example, information in kg) of the fuel tank possessed by the FC mobile body 50 is provided in each FC mobile body 50. When the FC mobile body 50 enters the waiting place 40, information indicating the vehicle number and the free capacity of the fuel tank is sent from the system to the manufacturing plan generation system 10.

[0049] The manufacturing plan generating system 10 stores information related to the FC mobile body 50 parked at the waiting place 40 through a database or the like. This information is used for the manufacturing plan of hydrogen and the rental of the FC mobile body 50. This information is obtained by, for example, establishing correspondence between the vehicle number of each FC mobile body 50, information indicating whether hydrogen is fully filled in the fuel tank, and information indicating the free capacity of the fuel tank. The free capacity of the fuel tank of the FC mobile body 50 parked at the waiting place 40 is the supplyable amount (fillable amount) of hydrogen that can be supplied to the FC mobile body 50.

[0050] The manufacturing plan generating system 10 receives the vehicle number and the information indicating the free capacity of the fuel tank transmitted from the entering FC mobile body 50, and stores them in the above-mentioned database. Regarding the information indicating whether the fuel tank is fully filled with hydrogen, if the free capacity of the fuel tank is zero, it is considered to be fully filled, and if the free capacity of the fuel tank is not zero, it is considered to be not fully filled.

[0051] In addition, usually, the filling of hydrogen into the fuel tank of the FC mobile body 50 is not carried out until the fuel tank capacity (theoretical value) is fully reached. When the FC mobile body 50 is filled with high-pressure hydrogen at the hydrogen station 30, the filled hydrogen generates heat. The fuel tank of the FC mobile body 50 is not only limited by the upper limit of pressure, but also by the upper limit of temperature. In order not to exceed the upper limit, the filled hydrogen is cooled and the filling speed of the hydrogen is adjusted to prevent overheating of the fuel tank when the filling is completed. In actual filling, a target value of the filling amount of hydrogen is set in consideration of the outside gas temperature (used instead of the temperature of the fuel tank of the FC mobile body 50), the temperature of the cooled hydrogen to be filled, the pressure of the hydrogen remaining in the fuel tank of the FC mobile body 50, etc., and the filling is performed. The target value may have a margin, or may be set to about 90% of the capacity (theoretical value) of the fuel tank.

[0052] Therefore, the information indicating the free capacity of the above-mentioned fuel tank (the amount of hydrogen that can be supplied to the FC mobile body 50) maintained by the manufacturing plan generation system 10 can also be set to the value of the hydrogen filling amount of the fuel tank of the FC mobile body 50 at the current time point from the target value (the value of their difference). If the hydrogen filling amount of the fuel tank of the FC mobile body 50 at the current time point is greater than the target value, the free capacity of the fuel tank is set to zero. The target value can be set to a preset value (for example, 90% of the capacity (theoretical value) of the fuel tank), or it can be a value calculated as described above for each FC mobile body 50. In this case, the information indicating whether the filling is completed is set to information based on the free capacity.

[0053] The FC mobile body 50 that has been fully charged is set to be available for rent, and the FC mobile body 50 that has not been fully charged is set to be unavailable for rent. The information in the above database is updated according to the filling of hydrogen into the FC mobile body 50 and the rental of the FC mobile body 50 as described later.

[0054] As described later, in the present embodiment, a hydrogen production plan is generated at the time when the FC mobile body 50 enters the standby place 40. The condition information acquisition unit 11 acquires information indicating the free capacity of the fuel tanks of all FC mobile bodies 50 stored in the above database as condition information when the FC mobile body 50 enters the standby place 40 and updates the information related to the FC mobile body 50 in the above database. In addition, the condition information acquisition unit 11 may also acquire other condition information at the same time.

[0055] In addition, the hydrogen production plan may be generated at a timing other than the above. The condition information acquisition unit 11 only needs to acquire the condition information at a timing appropriate for the condition information.

[0056] The manufacturing plan generation system 10 stores information indicating the storable amount of hydrogen in the accumulator 34, that is, the free capacity (for example, in Nm3) through a database or the like. This information is updated according to the storage of hydrogen in the accumulator 34 and the supply of hydrogen from the accumulator 34 to the FC mobile body 50 as described later. The condition information acquisition unit 11 acquires the information indicating the free capacity of the accumulator 34 stored in the above-mentioned database as condition information.

[0057] The condition information acquisition unit 11 may also acquire information indicating the hydrogen manufacturing capacity of the hydrogen manufacturing device 31 as condition information indicating one of the above conditions. For example, the information indicating the hydrogen manufacturing capacity of the hydrogen manufacturing device 31 is, for example, information indicating the amount of hydrogen (for example, in units of Nm3) that can be manufactured per unit time (for example, the unit time of the hydrogen manufacturing plan, i.e., 30 minutes). The condition information acquisition unit 11, for example, acquires information indicating the hydrogen manufacturing capacity of the hydrogen manufacturing device 31 pre-stored in the manufacturing plan generation system 10. The condition information acquisition unit 11 may also acquire condition information other than the above. The condition information acquisition unit 11 outputs the acquired condition information to the manufacturing plan generation unit 12.

[0058] The manufacturing plan generation unit 12 is a functional unit that sets the upper limit of the fuel to be manufactured based on the condition information acquired by the condition information acquisition unit 11, and generates a manufacturing plan including the manufacturing time and manufacturing amount of the fuel. The manufacturing plan generation unit 12 may also acquire information indicating the manufacturing cost of the fuel at each time, and also generate a manufacturing plan based on the manufacturing cost. The manufacturing cost of hydrogen as a fuel may also include the price of electricity. The manufacturing plan generation unit 12 may also generate a manufacturing plan based on the information indicating the manufacturing capacity of the fuel of the manufacturing device acquired by the condition information acquisition unit 11. For example, the manufacturing plan generation unit 12 generates a manufacturing plan for hydrogen as a fuel as follows.

[0059] The hydrogen manufacturing plan generated by the manufacturing plan generating unit 12 is, for example, a manufacturing plan for the day when the manufacturing plan is generated, or after the time when the manufacturing plan is generated, that is, a manufacturing plan for one day. Alternatively, the generated hydrogen manufacturing plan may also be a manufacturing plan for a certain period of time after the time when the manufacturing plan is generated.

[0060] The manufacturing plan generating unit 12 receives the condition information from the condition information acquiring unit 11. When commercial power is used in the manufacturing of hydrogen, the manufacturing plan generating unit 12 acquires information on the power price at each time as information indicating the manufacturing cost of hydrogen. The power price is the power price at the time of manufacturing hydrogen related to the manufacturing plan, that is, in the future. The power price is, for example, the price per unit of power, such as Figure 2 As shown, it is the price every 30 minutes as the unit time of the hydrogen manufacturing plan. However, the information on electricity prices may also be information other than the above. For example, the manufacturing plan generation unit 12 may also obtain information on electricity prices provided by a power company that supplies commercial electricity. Alternatively, the manufacturing plan generation unit 12 may also obtain information on electricity prices predicted based on past electricity prices. In addition, the manufacturing plan generation unit 12 may also obtain information on electricity prices by other methods.

[0061] The manufacturing plan generation unit 12 generates a hydrogen manufacturing plan based on the input condition information and the acquired information on the electricity price. For example, the manufacturing plan generation unit 12 generates a hydrogen manufacturing plan using a mathematical programming method such as a linear programming method. Specifically, the manufacturing plan generation unit 12 pre-stores a mathematical model for generating a hydrogen manufacturing plan. The decision variable of the mathematical model is the production amount of hydrogen at each moment.

[0062] The limitations of the mathematical model include an upper limit on the amount of hydrogen produced. Specifically, the total amount of hydrogen produced is less than the sum of the free capacity of the fuel tank of the FC mobile body 50 and the free capacity of the accumulator 34 represented by the conditional information. In addition, in the mathematical model, when defining the limitation, the unit of the free capacity of the fuel tank of the FC mobile body 50 and the unit of the free capacity of the accumulator 34 are matched to a certain unit. In addition, the limitations of the mathematical model include the limitation that the amount of hydrogen produced at each moment (unit time) is less than the amount of hydrogen that can be produced represented by the conditional information. In addition, the limitations of the mathematical model may also include limitations other than the above. The objective function of the mathematical model is the manufacturing cost of hydrogen corresponding to the amount of hydrogen produced. In the objective function, the price of electricity represented by the acquired information is set as a parameter.

[0063] The production plan generating unit 12 calculates (generates) a hydrogen production plan as an optimal solution to the mathematical model so as to minimize the objective function, that is, the production cost of hydrogen. The calculation using the mathematical model can be performed using a conventional mathematical programming method.

[0064] According to the above production plan, hydrogen production device 31 can be operated at full capacity during the period of low electricity prices to produce hydrogen. For example, a production plan can be set such that 100% operation is performed from 10 am to 11 am and stopped from 11 am to 12 am.

[0065] In addition, the generation of the hydrogen manufacturing plan by the manufacturing plan generation unit 12 may be performed by a method other than the above as long as the upper limit of the hydrogen to be manufactured is set based on the condition information. For example, when electricity other than commercial electricity is used in the manufacture of hydrogen, information on the cost corresponding to the electricity may be used. In addition, the generation of the hydrogen manufacturing plan by the manufacturing plan generation unit 12 may be performed by a method other than the above without setting the upper limit of the hydrogen to be manufactured as long as the generation is performed based on the condition information.

[0066] The manufacturing plan generating unit 12 outputs information indicating the manufacturing plan of the generated hydrogen. For example, the manufacturing plan generating unit 12 may send the information to other devices, or may display the information on a display device provided in the manufacturing plan generating system 10. In addition, the manufacturing plan generating unit 12 may also output the information to the vehicle management unit 13.

[0067] The production plan generation unit 12 generates a hydrogen production plan at the time when the condition information acquisition unit 11 acquires the condition information, that is, the time when the FC mobile body 50 enters the standby place 40. This timing is the time when the conditions that restrict the production of hydrogen are changed from the previous conditions. If there is a time when the conditions that restrict the production of hydrogen are changed from the previous conditions in addition to the above, the production plan generation unit 12 can also reflect the change of the conditions at this time and newly generate a hydrogen production plan.

[0068] Furthermore, as described later, when the production plan needs to be regenerated in consideration of the rental of the FC vehicle 50, the production plan generator 12 generates a hydrogen production plan. In this case, restrictions corresponding to the above situation are added to the mathematical model used in generating the hydrogen production plan.

[0069] The vehicle management unit 13 is a functional unit that manages the availability of vehicles based on the supply of fuel to the vehicle generated based on the manufacturing plan generated by the manufacturing plan generation unit 12. The vehicle management unit 13 may also determine whether there is an available vehicle based on the free capacity of the fuel tank of the vehicle corresponding to the supply of fuel to the vehicle based on the manufacturing plan generated by the manufacturing plan generation unit 12. The vehicle management unit 13 may also add new restrictions related to the supply of fuel to the vehicle used by the specified user and instruct the manufacturing plan generation unit 12 to generate a new manufacturing plan when it is determined that there is no available vehicle and the storage amount of the generated fuel does not meet the conditions related to the supply of the fuel to the vehicle used by the specified user. For example, the vehicle management unit 13 performs the following management.

[0070] In the hydrogen manufacturing device 31 of the hydrogen station 30, hydrogen is produced according to the manufacturing plan generated by the manufacturing plan generating unit 12. In the case where a new manufacturing plan is generated by the manufacturing plan generating unit 12 for a time when a manufacturing plan has already been generated by the manufacturing plan generating unit 12, hydrogen is produced according to the new manufacturing plan. That is, the manufacturing plan is always updated to the latest plan.

[0071] The hydrogen produced by the hydrogen manufacturing device 31 is first stored in the accumulator 34 after being pressurized by the compressor 33. When the accumulator 34 stores hydrogen and there is an FC mobile body 50 parked at the waiting place 40 that has not been fully filled with hydrogen (not full), hydrogen is filled from the accumulator 34 to the FC mobile body 50. When there are multiple FC mobile bodies 50 that are to be filled with hydrogen, the FC mobile body 50 is filled with hydrogen in a prescribed order. For example, the FC mobile body 50 is filled with hydrogen in the order from morning to night when it enters the waiting place 40. Alternatively, the FC mobile body 50 with a small free capacity of the fuel tank, in other words, the time taken to fill the fuel tank with hydrogen is short, may be preferentially filled with hydrogen. Alternatively, when there is no FC mobile body 50 of a model that has been fully filled with hydrogen at the waiting place 40, the FC mobile body 50 of that model may be preferentially filled with hydrogen.

[0072] When the FC mobile body 50 is filled with hydrogen, the vehicle management unit 13 obtains the vehicle number of the FC mobile body 50 and information indicating the filling amount of hydrogen. This acquisition is performed, for example, by receiving information sent from the FC mobile body 50, the hydrogen station 30, or the operator's terminal. Based on the received information, the vehicle management unit 13 updates the database of information related to the FC mobile body 50 possessed by the manufacturing plan generation system 10. Specifically, the free capacity of the fuel tank of the FC mobile body 50 with the received vehicle number is subtracted from the filling amount of hydrogen indicated by the received information. When the free capacity of the fuel tank becomes zero, the vehicle management unit 13 changes the FC mobile body 50 with the vehicle number in the database to the fuel tank being fully filled with hydrogen (full), that is, it can be rented.

[0073] The vehicle management unit 13 also acquires information indicating the amount of hydrogen produced by the hydrogen production device 31 and stored in the accumulator 34 , and updates the storable amount of hydrogen, ie, the free capacity, of the accumulator 34 in the database included in the manufacturing plan creation system 10 .

[0074] When there is a request to rent the FC mobile body 50, the vehicle management unit 13 receives information indicating this, reads out the vehicle number of the FC mobile body 50 that can be rented, that is, the FC mobile body 50 whose fuel tank is fully filled with hydrogen, from the database and outputs it. Based on the output of this information, the FC mobile body 50 is rented to the user. When the FC mobile body 50 is rented, the vehicle management unit 13 receives information indicating this, and deletes the information of the rented FC mobile body 50 from the above-mentioned database. In addition, the input and output of information of the above-mentioned manufacturing plan generation system 10 is performed, for example, between the terminal of the operator (the same applies below).

[0075] In addition, when the user causes the FC mobile body 50 to enter the waiting place 40 and wants to transfer to another FC mobile body 50 of the same model that has been filled with hydrogen, the vehicle management unit 13 refers to the database to determine whether there is an FC mobile body 50 of the same model as the FC mobile body 50 that has entered and can be rented. When the vehicle management unit 13 determines that there is an FC mobile body 50 that can be rented, it reads the vehicle number of the FC mobile body 50 from the database and outputs it. For example, the vehicle management unit 13 sends the vehicle number of the FC mobile body 50 that can be rented (the FC mobile body 50 that can be transferred) to the system of the FC mobile body 50 that has entered (the FC mobile body 50 before the transfer) to notify the user. Based on the output of this information, the FC mobile body 50 is rented to the user, and as described above, the user can transfer to another FC mobile body 50 that has been filled with hydrogen.

[0076] When the vehicle management unit 13 determines that there is no FC mobile body 50 available for rent, that is, when the user brings the FC mobile body 50 into the waiting place 40, there is no other FC mobile body 50 of the same model that has been filled with hydrogen in the waiting place 40 and the user continues to rent the FC mobile body 50, the FC mobile body 50 rented to the user so far continues to be rented after being filled with hydrogen.

[0077] The vehicle management unit 13 refers to the database provided in the manufacturing plan generation system 10 to determine whether the accumulator 34 stores enough hydrogen to fill the FC mobile body 50 at that time. When the vehicle management unit 13 determines that the accumulator 34 stores enough hydrogen to fill the FC mobile body 50 at that time, the vehicle management unit 13 outputs information indicating that the FC mobile body 50 is filled with the hydrogen stored in the accumulator 34. Based on the output of the information, the FC mobile body 50 is filled with hydrogen from the accumulator 34, and the user continues to rent the FC mobile body 50.

[0078] When the vehicle management unit 13 determines that the accumulator 34 does not store enough hydrogen to fill the FC mobile body 50 at this point in time, the vehicle management unit 13 instructs the manufacturing plan generation unit 12 to generate a new hydrogen manufacturing plan. The generated hydrogen manufacturing plan is a manufacturing plan that can manufacture hydrogen that can fill the FC mobile body 50 as quickly as possible. Specifically, the manufacturing plan generation unit 12 adds the restriction that the amount of hydrogen that can fill the FC mobile body 50 is manufactured at the earliest time under the hydrogen manufacturing capacity of the hydrogen manufacturing device 31 at the time of becoming the object of the manufacturing plan to the above-mentioned restriction, and generates a manufacturing plan in the same way as above. According to the manufacturing plan, when the amount of hydrogen that can fill the FC mobile body 50 is manufactured, hydrogen is filled into the FC mobile body 50 from the accumulator 34, and the user continues to rent the FC mobile body 50.

[0079] The vehicle management unit 13 may also be input with information indicating the hydrogen manufacturing plan from the manufacturing plan generation unit 12. According to the hydrogen manufacturing plan, it is possible to grasp at what time and how much hydrogen is manufactured. The vehicle management unit 13 may also calculate the time of filling hydrogen for each FC mobile body 50 parked at the waiting place 40 according to the manufacturing amount corresponding to the time of manufacturing based on the manufacturing plan and the above-mentioned pre-set hydrogen filling reference for the FC mobile body 50.

[0080] The vehicle management unit 13 outputs information indicating the scheduled time for filling hydrogen to each FC mobile body 50, so that hydrogen can be filled at the time calculated for each FC mobile body 50. For example, the vehicle management unit 13 sends information indicating the above-mentioned time for each FC mobile body 50 to the operator's terminal (for example, information that vehicle A is scheduled to be filled with hydrogen at 10:30). The operator fills the FC mobile body 50 with hydrogen according to the information and sends information indicating its performance to the manufacturing plan generation system 10 (for example, information that vehicle A completed hydrogen filling at 10:40). The vehicle management unit 13 receives the information and updates the database as described above. The above is the function of the manufacturing plan generation system 10 involved in the present embodiment.

[0081] Next, use Figure 3 The processing performed by the manufacturing plan generation system 10 according to the present embodiment (the operation method performed by the manufacturing plan generation system 10), i.e., the manufacturing plan generation method, is described with reference to the flowchart of FIG. This processing is a processing in the case where the user rents and uses the FC mobile body 50, and the FC mobile body 50 with reduced hydrogen as fuel enters the standby place 40 and continues to rent it.

[0082] When the FC mobile body 50 enters the waiting place 40, the manufacturing plan generating system 10 receives the vehicle number and the information indicating the free capacity of the fuel tank transmitted from the FC mobile body 50, and stores it in the database (S01). Then, the vehicle management unit 13 refers to the database to determine whether there is an FC mobile body 50 of the same model as the FC mobile body 50 that has entered and that can be rented (S02, vehicle management step).

[0083] If there is an FC mobile body 50 that can be rented (S02: "Yes"), the vehicle management unit 13 outputs the vehicle number of the FC mobile body 50 that can be rented (the FC mobile body 50 that can be transferred), and the user transfers to the FC mobile body 50. If there is no FC mobile body 50 that can be rented (S02: "No"), the user fills the FC mobile body 50 that has been rented so far with hydrogen and continues to rent it. If the accumulator 34 stores hydrogen that can fill the FC mobile body 50, hydrogen is filled into the FC mobile body 50 from the accumulator 34, and the user continues to rent the FC mobile body 50.

[0084] In the case where the accumulator 34 does not store enough hydrogen to fill the FC mobile body 50, if the hydrogen manufacturing device 31 manufactures hydrogen according to the manufacturing plan generated by the manufacturing plan generation system 10, the FC mobile body 50 is filled with hydrogen from the accumulator 34, and the user continues to rent the FC mobile body 50. In this case, the vehicle management unit 13 sets an additional manufacturing condition (restriction) for the manufacturing plan for generating hydrogen (S03, vehicle management step). The additional manufacturing condition is a restriction that the amount of hydrogen in the free capacity of the FC mobile body 50 is manufactured at the earliest time under the hydrogen manufacturing capacity of the hydrogen manufacturing device 31 at the time of becoming the object of the manufacturing plan.

[0085] After "Yes" in S02 or S03, the condition information acquisition unit 11 acquires the condition information (S04, condition information acquisition step). Next, the manufacturing plan generation unit 12 acquires the information of the electricity price at each moment as information indicating the manufacturing cost of hydrogen (S05, manufacturing plan generation step). Next, the manufacturing plan generation unit 12 generates a hydrogen manufacturing plan (S06, manufacturing plan generation step). The upper limit of the hydrogen to be manufactured is set based on the condition information, and the hydrogen manufacturing plan is generated. In addition, the hydrogen manufacturing plan is generated by taking into account the information of the electricity price at each moment.

[0086] Next, the production plan generating unit 12 outputs the production plan of the produced hydrogen ( S07 ). According to the output production plan of hydrogen, hydrogen is produced in the hydrogen production device 31 of the hydrogen station 30 . The produced hydrogen is filled in the FC mobile body 50 .

[0087] In addition, the vehicle management unit 13 outputs information related to the FC mobile body 50 and hydrogen and updates the database (S08, vehicle management step) based on the output of the hydrogen manufacturing plan, the manufacturing of hydrogen, and the filling of hydrogen into the FC mobile body 50 as described above. For example, the vehicle management unit 13 manages the update of the availability of the FC mobile body 50 based on the supply of hydrogen generated based on the hydrogen manufacturing plan to the FC mobile body 50. The above is the processing performed by the manufacturing plan generation system 10 involved in this embodiment.

[0088] In the present embodiment, the upper limit amount of hydrogen to be produced is set based on the condition information including information indicating the free capacity of the fuel tank of the FC mobile body 50 as the supplyable amount of hydrogen that can be supplied to the FC mobile body 50, and a production plan is generated. Therefore, the generated production plan can be set as a production plan that takes the supply to the FC mobile body 50 into consideration, and as a result, the production cost of hydrogen supplied to the FC mobile body 50 can be suppressed.

[0089] For example, compared to the conventional case where the amount of hydrogen to be filled in the FC mobile body is produced when the FC mobile body arrives at the hydrogen station, the restriction is relaxed, so that the manufacturing cost can be suppressed. Specifically, in the conventional case, hydrogen needs to be produced at irregular times and the hydrogen production cannot be controlled, but in the present embodiment, the hydrogen production can be controlled such that hydrogen is produced and stored during a time period when the electricity price is low.

[0090] exist Figure 4 2 shows a comparison between the above-mentioned case (normal) and the case (optimum supply) according to the present embodiment. Figure 4 Show Figure 2 Examples of scenarios for electricity prices and hydrogen demand are shown. Figure 2 The hydrogen demand in φ indicates the time when the FC mobile body, which is the target of hydrogen supply, appears and the available supply amount of hydrogen (required supply amount). Figure 2 The hydrogen demand value is the value (Nm3) shown on the right side of the graph. Figure 4 In the example shown, the pressure accumulator 34 is not used in both normal and optimal supply.

[0091] Figure 4 (a) is a table showing the hydrogen production timing, average production cost, and maximum hydrogen storage amount for normal and optimal supply. Figure 4 (b) is a graph showing values ​​obtained by accumulating the power price at each time point in each case. Figure 4 (c) is a graph showing the amount of hydrogen produced at each time. Figure 4 As shown in (c), in the optimal supply, hydrogen production is not performed after 15:00, which is a time period with high electricity prices. Therefore, in this embodiment, the production cost of hydrogen can be reduced compared to the past. In addition, in the case of a fuel storage device such as an accumulator, the restrictions are relaxed compared to the above-mentioned normal situation (the case where the produced hydrogen is not stored), but if the supply amount of hydrogen that can be supplied to the FC mobile body 50 is not considered as in this embodiment, the reduction in the production cost of hydrogen as described above cannot be achieved.

[0092] In addition, the upper limit of the fuel to be produced may be set based on the condition information as in the present embodiment, and a production plan may be generated. According to this structure, the production cost of the fuel provided to the FC mobile body 50 can be more appropriately and reliably suppressed. However, the production plan may be generated by a method other than the above without setting the upper limit of the hydrogen to be produced, as long as it is based on the condition information.

[0093] In addition, as in the present embodiment, condition information indicating the storable amount of hydrogen related to a storage device capable of storing the manufactured fuel other than the FC mobile body 50, for example, the accumulator 34 in the present embodiment, may be used. According to this structure, the manufacturing plan can be set as a manufacturing plan that considers the storage to the storage device in addition to the supply to the FC mobile body 50, and as a result, the manufacturing cost of the fuel supplied to the FC mobile body 50 can be further suppressed. However, it is not necessarily necessary to use the condition information related to the storage device. In addition, the storage device may be a device other than the accumulator 34 as long as it can store the manufactured fuel.

[0094] In addition, as in the present embodiment, information indicating the manufacturing cost of hydrogen at each moment, that is, the price of electricity, may be obtained, and a manufacturing plan may be generated based on the information. In addition, it may be set that the fuel being manufactured is hydrogen, and the manufacturing cost of the fuel is the price of electricity. According to this structure, a manufacturing plan that suppresses the manufacturing cost of hydrogen can be appropriately and reliably generated. However, it may also be set that a structure that does not use information indicating the manufacturing cost is used. In addition, information indicating the manufacturing cost of the fuel other than the price of electricity may also be used. In addition, the fuel of the vehicle may also be a fuel other than hydrogen. In addition, the vehicle may also be a vehicle other than an FC mobile body.

[0095] In addition, the availability of the FC mobile body 50 may be managed based on the supply of hydrogen to the FC mobile body 50 generated based on the generated manufacturing plan, as in the vehicle management unit 13 of the present embodiment. According to this configuration, in the rental of the FC mobile body 50 as in the present embodiment, the FC mobile body 50 can be appropriately managed based on the generated manufacturing plan. However, it is not necessarily necessary to manage the availability of the FC mobile body 50.

[0096] In addition, as in the vehicle management unit 13 of the present embodiment, it is also possible to determine whether there is an available FC mobile body 50 based on the free capacity of the fuel tank of the FC mobile body 50 corresponding to the supply of fuel to the FC mobile body 50 based on the manufacturing plan. With this configuration, the FC mobile body 50 can be managed more appropriately.

[0097] In addition, as in the vehicle management unit 13 of the present embodiment, when it is determined that there is no available FC mobile body 50 and the storage amount of the generated fuel does not satisfy the conditions related to the supply of the fuel to the FC mobile body 50 used by the specified user, a new restriction related to the supply of the fuel to the FC mobile body 50 used by the specified user may be added, and a new manufacturing plan may be instructed to be generated. According to this structure, an appropriate manufacturing plan that also corresponds to the availability of the FC mobile body 50 can be generated. However, the manufacturing plan generation system 10 does not necessarily need to have the above-mentioned function of the vehicle management unit 13.

[0098] In addition, as in the present embodiment, when the FC mobile body 50 enters a preset parking space, information indicating the free capacity of the fuel tank of the FC mobile body 50 transmitted from the FC mobile body 50 may be obtained as information indicating the available supply amount of fuel that can be supplied to the FC mobile body 50. According to this structure, information for generating a manufacturing plan can be appropriately and reliably obtained. As a result, the manufacturing cost of the fuel supplied to the FC mobile body 50 can be more appropriately and reliably suppressed. However, the information indicating the available supply amount of fuel that can be supplied to the FC mobile body 50 may also be obtained by methods other than the above.

[0099] In addition, as in the present embodiment, information indicating the fuel manufacturing capability of the hydrogen manufacturing device 31 for manufacturing the fuel of the FC mobile body 50 may be obtained, and a manufacturing plan may be generated based on the information indicating the fuel manufacturing capability of the hydrogen manufacturing device 31. According to this structure, it is possible to generate an appropriate manufacturing plan that also corresponds to the fuel manufacturing capability of the hydrogen manufacturing device 31. However, in generating the manufacturing plan, the information indicating the fuel manufacturing capability of the hydrogen manufacturing device 31 may not necessarily be used.

[0100] In addition, the FC mobile body 50 may be a rented FC mobile body as in the present embodiment. According to this structure, the manufacturing cost of the fuel provided to the rented FC mobile body 50 can be suppressed more appropriately and more reliably. However, the FC mobile body 50 that is the object does not necessarily need to be a rented FC mobile body, and may be any FC mobile body. That is, the present embodiment is based on the rental of the FC mobile body 50, but an embodiment of the present invention does not necessarily need to be implemented under such a premise, as long as it is an embodiment that generates a fuel manufacturing plan by considering the supplyable amount of fuel that can be supplied to a vehicle that can be supplied with the manufactured fuel.
