Then, the operator removes the fuel nozzle 23 corresponding to the selected and designated oil type from the nozzle storage unit 25 in the selected and specified refueling machine 20, and inserts the nozzle cylinder tip into the liquid supply port of the fuel traveling automobile 9f to be supplied. Then, the operation lever is opened to start fuel discharge to the fuel vehicle. On the other hand, when the refueling operation is finished, the operator closes the operation lever of the refueling nozzle 23 to end the fuel discharge, removes the nozzle cylinder tip from the liquid supply port, and then removes the refueling nozzle 23. It is stored in the original nozzle storage unit 25.

  At that time, in the fueling machine 20, a fueling control device 27 provided in the fueling machine housing 21 is adapted to a liquid feeding / measurement system 24 including a pump and a flow meter in accordance with the progress of the fueling work described above by the worker. Operation control of each part of the fueling machine such as the indicator 29 is performed. Also, the refueling control device 27 transmits a refueling permission request and a refueling end notification including refueling information for issuing a slip to the POS for communication stations connected in communication with the progress of the refueling work by the worker described above. Or a refueling permit including a refueling work condition transmitted in response to a refueling permission request from the refueling station POS can be received. The oil supply control device 27 includes a CPU, a memory, and a microcomputer having an interface for communication and input / output.

  FIG. 3 is a configuration diagram of an embodiment of a charger that is communicatively connected to the energy supply management device. FIG. 3A shows a front view of the charger with the door of the cable storage chamber closed, and FIG. 3B shows a front view of the charger with the door of the cable storage chamber opened.

  In the illustrated example, the charger 30 includes a charging cable 34 having a charging connector 35 at the tip in a cable storage chamber 33 covered with an openable / closable door 32 on the front side of the charger housing 31. A touch panel display 38 as an operation / display unit is provided on the upper surface portion of the container housing 31. The charging connector 35 is configured to be detachable from the charging outlet of the electric vehicle 9e, and the connection end has a structure having various connection terminals for power supply, communication, and the like. When waiting for work, that is, when not being used for charging work, the charging connector 35 is held by the connector holding portion 36, and the charging cable 34 is wound around and supported by the cable latch 37 and is received in the cable storage chamber 33. Yes. And the base end side of the charging cable 34 is connected in the charger housing | casing 31 to the charging circuit 39 connected with the original power supply (for example, commercial power supply of single phase AC200V).

  In the charging operation, first, when starting the charging operation, the operator selects and designates the charger 30 to be used in the charging operation, for example, by operating the setting terminal of the POS 19 for the gas station, and charging to be performed from now on. Set and input work conditions. Then, the operator opens the door 32 of the charger housing 31 in the charger 30 selected and designated, takes out the charging connector 35 and the charging cable 34 from the cable storage chamber 33, and connects the charging connector 35 to the electric vehicle to be charged. Attach to the charging outlet of 9e and start charging the rechargeable battery mounted on the electric vehicle 9e. On the other hand, when finishing the charging operation, the operator operates the lock release button of the charging connector 35 to remove the charging connector 35 from the charging outlet, and accommodates the charging connector 35 and the charging cable 34 in the cable storage chamber 33. After that, the door 32 of the charger 30 is closed.

  At that time, in the charger 30, the charging circuit 39 provided in the charger housing 31 supplies the charging connector 35 and the charging cable 34 from the main power source in accordance with the progress of the above-described charging operation by the worker. Electricity is generated, and supply of the generated charging electricity from the charging connector 35 and the charging cable 34 is controlled. Moreover, the charging circuit 39 measures the amount of charging electricity and the charging time supplied from the charging connector 35 to the electric vehicle 9e to be charged. In addition, the charging circuit 39 transmits a charging permission request and a charging end notification including charging information for issuing a slip to the communication-connected gas station POS, or responds to the charging permission request from the gas station POS. The charging permission / prohibition including the charging work condition transmitted is received. The charging circuit 39 includes a CPU, a memory, and a microcomputer having an interface for communication and input / output.

  In the charger 30, a charging control circuit (CCID: Charging Circuit Interrupt Device) controls supply / stop of charging electricity to the electric vehicle 9e to be charged, that is, charging start / end of charging to the charging target. . The charging control circuit has a relay and a control pilot circuit, and has a communication function using a pilot signal with the in-vehicle charging control device on the electric vehicle 9e side to which the charging connector 35 is connected. Based on the response supplied from the in-vehicle charging control device of the electric vehicle 9e as the charging of the rechargeable battery progresses, the charging electricity from the charging connector 35 to the rechargeable battery connected to the charging outlet is supplied / stopped. The charging control circuit is arranged in the charger casing 31 together with the charging circuit 39 or in the middle of the charging cable 34.

  As shown in FIG. 1, the POS for the gas station is connected to the SS-LAN used for communication between the POS terminal 19 for the gas station and each of the plurality of oilers 20-1 to 20-3 and the chargers 30-1 to 30-3. In the case of the energy supply system 10 configured by communication connection of the energy supply management device 11 composed of a dedicated computer device different from the computer device of the terminal 19, it is transmitted from the above-described fueling machine 20 to the POS terminal 19 for the gas station. The refueling permission request and the refueling end notification, and the charging permission request and recharging end notification transmitted from the charger 30 to the POS terminal 19 for the gas station once pass through the energy supply management device 11 from each of the refueling device 20 and the charger 30. Thus, the communication configuration is transmitted to the POS terminal 19 for the gas station. In addition, the refueling permission and the charging permission transmitted from the POS 19 for the gas station to the refueling machine 20 and the charger 30 are respectively transmitted from the POS terminal 19 for the gas station via the energy supply management device 11 to each of the refueling machine 20 and the charger 30. The communication configuration is transmitted to the network. Therefore, even in the energy supply system 10 as shown in FIG. 1, the energy supply management device 11 is similar to the case where the gas station POS terminal also has a function as the energy supply management device 11. A refueling permission request, a refueling end notification, a charging permission request, and a charging end notification transmitted from the refueling station POS 19 to the refueling station POS 19 can be acquired, and the refueling permission transmitted from the refueling station POS 19 to the refueling machine 20 and the charger 30 respectively. In addition, transmission control of charging permission can be made to each of the fuel filler 20 and the charger 30.

  Next, taking the energy supply station 1 to which the energy supply system 10 shown in FIG. 1 is applied as an example, the relationship between the fuel supply work area 20P and the charging work area 30P in the energy supply station 1 will be described with reference to FIGS. Based on the explanation.

  FIG. 4 is a diagram illustrating the relationship between the fuel supply work area and the charging work area in the energy supply station shown in FIG. 4A is a front view of the fuel supply work area and the charging work area, and FIG. 4B is a plan view of the fuel supply work area and the charge work area shown in FIG. 4A.

  FIG. 5 is an explanatory diagram of a relationship between each fuel supply work area and each charge work area in the energy supply station shown in FIG.

  In the energy supply station 1 shown in FIG. 1, as shown in FIG. 4, one refueling machine 20 and one charger 30 are installed on the island 3 with an appropriate distance therebetween. . Therefore, the refueling work area (fuel supply work position) 20P by the refueling machine 20 and the charging work area (charging work position) 30P by the charger 30 are as shown in FIGS. 4 (A) and 4 (B). 3 are formed side by side along the extending direction. In this case, the size of the refueling work area 20P substantially corresponds to the range that the refueling nozzle 23 of the refueling machine 20 can reach, and the size of the charging work area 30P approximately corresponds to the range that the charging connector 35 of the charger 30 can reach. ing. In the illustrated example, the fuel-driven vehicle 9f that receives the fuel supply and the electric vehicle 9e that receives the charge are located in the area of the fueling work area 20P or the charging work area 30P with the liquid supply port or the charging outlet provided in the vehicle, respectively. In this way, the vehicle stops in a column along the extending direction of the island 3.

  By the way, the arrangement relationship between one refueling machine 20 and one charger 30 can prevent the fuel vapor around the refueling machine 20 from entering the vicinity of the charging machine 30 during the charging operation by the charger 30. Therefore, it is preferable that the refueling machine 20 and the charger 30 are separated so that the refueling work area 20P and the charging work area 30P do not overlap. Further, with respect to the separation distance, even when the liquid supply port position of the fuel traveling vehicle 9f stopped in the fueling work area 20P and the charging outlet position of the electric vehicle 9e stopped in the charging work area 30P are closest to each other, the fueling is performed. The fuel-side safety distance (fuel-supply-side safety distance) d1 at which fuel vapor overflowing from the liquid supply port sufficiently diffuses as the liquid level in the fuel tank rises during work and the charging connector 35 of the charger 30 during charging work It is preferable that the distance is equal to or greater than the total safety distance ds (= d1 + d2) including the charging-side safety distance d2 that is the movable range.

  However, in the actual energy supply station 1, due to restrictions on the expansion of the site and the arrangement of facilities and facilities such as fuel supply devices in the site, as shown in FIG. Even if the charging work area 30P can be separated from the charging work area 30P, the refueling work area 20Ps in consideration of the refueling side safety distance d1 becomes the charging work area 30Ps in consideration of the charging work area 30P and the charging side safety distance d2. The charging work area 30Ps in consideration of the charging-side safety distance d2 must overlap with the fueling work area 20P and the fueling work area 20Ps in consideration of the fueling-side safety distance d1.

  The fueling work area 20Ps in consideration of the fueling side safety distance d1 and the charging work area 30Ps in consideration of the charging side safety distance d2 are installed on the same island 3 as shown in FIG. In addition, the energy supply station 1 is not limited to a single refueling machine 20 and a single charger 30, and a plurality of refueling machines 20 or a plurality of chargers 30 are provided in the site. It can also occur between each of the fuel fillers 20 and one charger 30 or between each of the fuel filler 20 and each of the plurality of chargers 30.

  For example, in the example shown in FIG. 5, in the energy supply station 1, three islands 3 (3-1, 3-2, 3-3) are larger than the vehicle width interval of the fuel vehicle 9f and the electric vehicle 9e. It is configured to be arranged in parallel along the direction intersecting the extending direction of the island 3 with an interval. The refueling machine 20-1 is connected to the charger 30-1, the refueling machine 20-2 is connected to the charger 30-2 and the charger 30-3, and the refueling machine 20-3 is connected to the charger 30-3. On the other hand, the refueling work area 20Ps in consideration of the refueling side safety distance d1 and the charging work area 30Ps in consideration of the charging side safety distance d2 are overlapped.

  Therefore, in the energy supply system 10 of the present embodiment, as shown in FIG. 1, the energy supply management device 11 that is connected to each of the fuel fillers 20-1 to 20-3 and the chargers 30-1 to 30-3, Refueling (fuel supply) to the fuel-driven vehicle 9f by the refueling machines 20-1 to 20-3, and feeding (charging) to the electric vehicle 9e by the chargers 30-1 to 30-3, respectively, and a charger 30-1 to 3, based on the distance relationship between each of the refueling work areas 20 </ b> P- 1 to 20 </ b> P <b> 3 and the charging work areas 20 </ b> P- 1 to 20 </ b> P. It is configured so that it can be centrally managed according to the work priority relationship of the interlock setting table 12 (see FIG. 6) that is set and stored.

  In the interlock setting table 12 of the energy supply management device 11, the distance relation between each of the fuel fillers 20-1 to 20-3 and each of the chargers 30-1 to 3; Based on the separated state from each of the charging work areas 30P-1 to 30P-3, for example, according to the following <arrangement>, each of the refueling operations of the refueling machines 20-1 to 30-3 and each of the chargers 30-1 to 30-3 A work priority relationship with the charging work is preset.

<Arrangement 1>
A separation distance D between a certain refueling work area 20P-n (any one of n = 1 to 3) and a certain charging work area 30P-m (any one of m = 1 to 3) is determined in advance. When the set fuel-side safety distance d1 and the charging-side safety distance d2 are separated from the total safety distance ds (D> ds = (d1 + d2)), the corresponding fueling machine 20-n and the corresponding charger 30- There is no work priority relationship with m.

<Arrangement 2>
A separation distance D between a certain refueling work area 20P-n and a certain charging work area 30P-m is larger than a total safe distance ds obtained by adding a predetermined refueling side safety distance d1 and a charging side safety distance d2. If not (D ≦ ds = (d1 + d2)), a work priority relationship is generated between the corresponding fueling machine 20-n and the corresponding charger 30-m.

<Arrangement 3>
When the work priority relationship is generated between the fuel filler 20-n and the charger 30-m, the work by one of the preset priority devices in both the fuel filler 20 and the charger 30 is inferior to the other. Prioritize work with equipment.

  FIG. 6 is an explanatory diagram of an interlock setting table set and stored in the memory of the energy supply management device according to <Arrangement 3>, taking the energy supply station shown in FIG. 5 as an example.

  In the case of the energy supply station 1 shown in FIG. 5, between the charger 30-1 and the fueling device 20-1, between the charger 30-2 and the fueling device 20-2, the charger 30-3 and Since the refueling work area 20P and the charging work area 30P are not separated from the total safety distance ds between the refueling machines 20-2 and 20-3, a work priority relationship is generated between them. It will be.

  In the interlock setting table 12 shown in FIG. 6, between the fueling machine 20-1 and the charger 30-1, between the fueling machine 20-2 and the charger 30-2, and between the fueling machines 20-2 and 20-. 3 and the charger 30-3, the refueling device 20 side is a priority device, the charger 30 side is a subordinate device, and the refueling operation by the refueling device 20-n with a short working time is a long working time. It is set to give priority to the charging operation of the charger 30-m.

  The setting of the priority device and the subordinate device between the oil filler 20 and the charger 30 in the interlock setting table 12 is not limited to the above setting example, and for example, the charger 30-1 and the oil filler Any desired setting can be set using the input / output unit of the energy supply management device 11, such as the charger 30-1 side being a priority device and the fuel machine 20-1 side being a subordinate device. It is.

  In addition, in the energy supply system 10 according to the present embodiment, the energy supply management device 11 performs the refueling operation of each of the oil feeders 20-n and the charging of each of the chargers 30-m according to the following procedure. Control your work.

In the meantime, the supply of the oil liquid to the oil supply nozzle 23, that is, the supply of the oil liquid to the oil supply nozzle 23, is stopped for the fuel supply device 20-n, and the supply of the fuel tank to be supplied is stopped. Prevent the fuel vapor from overflowing as the liquid level rises in the fuel tank.

  Here, the priority device and the subordinate device are set. However, the present invention is not limited to this, and when the supply by one supply device (for example, the oil supply device) is just started or in operation, the other supply device ( For example, the configuration may be such that supply by a charger is prohibited (claim 1). Thereby, it is possible to prevent the fuel vapor from entering the vicinity of the charger during the charging operation.

<Procedure 3>
When the work by the priority device is completed, the energy supply management device 11 resumes the work by the subordinate device that has been stopped or suspended during the work by the priority device.

  Specifically, when the priority device is the fuel filler 20-n and the subordinate device is the charger 30-m, the energy supply management device 11 finishes the fuel supply work by the fuel filler 20-n, and the liquid supply port If the overflow of the fuel vapor accompanying the rise in the liquid level in the fuel tank stops, the charging operation by the charger 30-m is interrupted or stopped, and if the charging has been interrupted or stopped Resume the charging operation using the container 30-m.

In this case, the refueling work start signal is input as a nozzle disengagement detection signal of the nozzle switch 26 that opens / closes in response to the attachment / detachment (return / removal) of the refueling nozzle 23 with respect to the nozzle storage portion 25, or the fuel traveling vehicle. In the oil supply nozzle 23 provided with the insertion sensor for detecting the insertion / non-insertion state of the nozzle cylinder tip into the 9f liquid supply port, an input of an insertion detection signal of the insertion sensor, or the like is applicable.

  When the oil supply control device 27 detects the input of the oil supply operation start signal in step SD110, the oil supply control device 27 transmits an oil supply operation permission request (oil supply permission request) to the energy supply management device 11 connected in serial communication with the oil supply device 20-n. (SD120). After transmission, the refueling control device 27 receives a refueling work permission (refueling permission) or a refueling work prohibition (refueling prohibition) transmitted from the energy supply management device 11 to the refueling machine 20-n in response to this permission request. Wait (SD130, 140).

  When the fuel supply control device 27 receives the fuel supply permission from the energy supply management device 11 in step SD130, the fuel supply control device 27 starts the liquid supply control processing (fuel supply control processing) shown in steps SD150, 160, 170, 180, and 190. On the other hand, when the fuel supply control device 27 receives the fuel supply prohibition from the energy supply management device 11 in step SD140, the fuel supply control device 27 performs the liquid supply start prohibition processing (fuel supply start prohibition processing) shown in steps SD141 to SD145. In addition, in the liquid supply start prohibition process shown in steps SD141 to SD145, in <Agreement 3>, it is set that the charging work of the charger 30-m has priority over the refueling work by the fueling machine 20-n. This is a process performed by the fuel supply control device 27 in the oil dispenser 20-n of the subordinate device when the charger 30-m of the device is already being charged.

  In the liquid supply control process, the oil supply control device 27 activates the pump of the liquid supply / measurement system 24 corresponding to the selected oil supply nozzle 23, and if the valve opening lever operation of the oil supply nozzle 23 is performed by the operator, the oil supply is performed. The oil liquid of the liquid type selected from the nozzle 23 is brought into a dischargeable state (SD150). When the pump is started, the fuel supply control device 27 transmits to the energy supply management device 11 a refueling notification indicating that the refueling operation has started and the refueling machine 20-n is in a refueling work state (SD160). .

  Thus, in the fuel filler 20-n, after the pump is started in step SD150, the oil liquid can be discharged or discharged from the fuel filler nozzle 23 while the pump is being driven. Therefore, when the operator inserts the nozzle tube tip into the liquid supply port of the fuel traveling automobile 9f and opens the fuel nozzle 23, the fuel nozzle 23 supplies fuel to the fuel tank of the fuel traveling automobile 9f to be supplied. Will be supplied.

  After the notification of refueling is transmitted, the fuel supply control device 27 calculates the amount of fuel supplied to the supply target based on the output of the flow rate pulse transmitter attached to the flow meter of the liquid feeding / measurement system 24, and displays it on the display 29. While being displayed, the input of the refueling work end signal and the reception of the prohibition of refueling transmitted from the energy supply management device 11 are monitored (SD170, 180). In this case, the refueling work end signal corresponds to an input of a nozzle return detection signal from the nozzle switch 26 that responds to the retraction (storage) of the fuel supply nozzle 23 with respect to the nozzle storage portion 25.

  When the oil supply control device 27 detects the input of the oil supply operation end signal in step SD170, the oil supply control device 27 stops driving the pump activated in step SD150 (SD190), and transmits an oil supply end notification to the energy supply management device 11 (SD200). ), And ends the refueling machine processing related to this refueling operation.

  On the other hand, when the fuel supply control device 27 receives the fuel supply prohibition from the energy supply management device 11 before the end of the fuel supply operation in step SD180, the liquid supply interruption / stop processing (fuel supply interruption / stop processing shown in steps SD181 to 187). )I do.

  Here, the liquid feeding start prohibiting process shown in steps SD141 to SD145 and the liquid feeding interruption / stopping process shown in steps SD181 to 187 will be described.

  In the liquid feed start prohibition process and the liquid feed interruption / stop process, the priority of the charging work by the predetermined charger 30-m is given to the interlock setting table of the energy supply management device 11 with respect to the fueling work by the fueling machine 20-n. This is a subordinate process (non-priority process) on the fuel machine 20-n side when set to 12. In any process, the fuel supply control device 27 of the fuel supply device 20-n performs the reception of the prohibition of fueling transmitted from the energy supply management device 11.

  In the liquid supply start prohibition process shown in steps SD141 to SD145, when the fuel supply control device 27 receives the fuel supply prohibition from the energy supply management device 11 in step SD140 in response to the transmission of the permission request for the fuel supply operation shown in step SD120. The use failure indicating that the refueling work cannot be performed by using the refueling machine 20-n is notified, for example, by displaying it on the display 29 (SD141). As a result, the operator who has been trying to supply fuel to the supply target using this refueling machine 20-n is the refueling machine 20 in which the refueling machine 20-n is waiting for priority (subordinated). There is a charging operation with a predetermined charger 30-m that is currently in operation, giving priority over the refueling operation using the refueling device 20-n, and the refueling operation using the refueling device 20-n is started until the charging operation is completed. I can understand what I can't do.

  The oil supply control device 27 monitors the reception of the oil supply permission transmitted from the energy supply management device 11 and the input of the oil supply operation end signal after notifying that the oil supply device 20-n cannot be used in step SD141 ( SD143, 145). In this case, the refueling work end signal corresponds to an input of a nozzle return detection signal from the nozzle switch 26 that responds to the retraction (storage) of the fuel supply nozzle 23 with respect to the nozzle storage portion 25.

  When the refueling control device 27 receives the refueling permission from the energy supply management device 11 in step SD143, the refueling control device 27 performs the charging operation by the predetermined charger 30-m that has priority over the refueling operation by the refueling device 20-n. Is completed, the liquid feeding control process shown in steps SD150, 160, 170, 180, 190 is performed, and the refueling operation using this refueling machine 20-n is started. On the other hand, when the input of the refueling work end signal is confirmed in step SD145, the refueling end notification is transmitted to the energy supply management device 11 on the assumption that the current refueling work using this refueling machine 20-n has been stopped. (SD200), the refueling machine processing related to the current refueling operation is terminated.

  On the other hand, in the liquid supply interruption / stop process shown in steps SD181 to 187, the oil supply control device 27 stops driving the pump activated in step SD150 when receiving the oil supply prohibition from the energy supply management device 11 in step SD180. (SD181), a stop of refueling indicating that the refueling work that has been performed using the refueling machine 20-n is interrupted or stopped is notified by, for example, displaying on the display 29 (SD183). As a result, the operator who has supplied fuel to the supply target using this refueling machine 20-n has priority over the refueling work that has been performed using this refueling machine 20-n. Charging work is started, and the refueling machine 20-n becomes a priority waiting (subordinate) refueling machine 20-n, and charging work using the charger 30-m that has priority over the refueling work using this refueling machine 20-n. It is possible to grasp that the refueling operation using the refueling machine 20-n is interrupted until the operation is completed. Then, in step SD181, the pump is stopped and the oil liquid is no longer discharged from the oil supply nozzle 23, so that the liquid level in the fuel tank to be supplied does not rise. Fuel vapor overflowing from the mouth can be suppressed, and diffusion of fuel vapor around the liquid supply port can be promoted.

  As a result, the operator who has supplied the fuel to the refueling vehicle by using the refueling machine 20-n becomes the priority waiting (subordinated) of the refueling machine 20-n by the refueling stop notification, and this refueling machine 20- It is understood that the refueling work using the refueling machine 20-n is interrupted or stopped until the charging work with the newly started predetermined charger 30-m, which has priority over the refueling work using n, is completed. be able to. When the fuel supply operation is interrupted or stopped, fuel vapor based on the rise in the liquid level in the fuel tank is supplied from the supply port of the supply target while power is being supplied to the charge target by the charger 30-m as the priority device. As a result, the fuel vapor concentration around the liquid supply port can be reduced.

  After notifying the oil supply stop of the fuel machine 20-n in step SD183, the oil supply control device 27 monitors the reception of the oil supply permission transmitted from the energy supply management device 11 and the input of the oil supply operation end signal ( SD185, 187). In this case, the refueling work end signal corresponds to an input of a nozzle return detection signal from the nozzle switch 26 that responds to the retraction (storage) of the fuel supply nozzle 23 with respect to the nozzle storage portion 25.

  When the fuel supply control device 27 receives the fuel supply permission from the energy supply management device 11 in step SD185, the fuel supply control device 27 is charged by the predetermined charger 30-m that has given priority to the fuel supply operation using the fuel supply device 20-n. Assuming that the work has been completed, the liquid feeding control process shown in steps SD150, 160, 170, 180, 190 is performed, and the refueling work using this refueling machine 20-n is automatically restarted. On the other hand, when the input of the refueling work end signal is confirmed in step SD187, the refueling end notification is transmitted to the energy supply management device 11 on the assumption that the current refueling work using this refueling machine 20-n has been stopped. (SD200), the refueling machine processing related to the current refueling operation is terminated.

  Thus, in the fueling machine 20-n (n = 1 to 3) of the energy supply system 10, the fueling permission or the fueling prohibition supplied from the energy supply management device 11 in response to the transmission of the permission request for the fueling work is performed. In response to each reception, before the start of the oil supply from the pump to the oil supply nozzle 23, the start of the oil supply operation is permitted or the start of the oil supply operation is prohibited, and the oil supply from the pump to the oil supply nozzle 23 is performed. After the start, the refueling operation can be interrupted / stopped or resumed. Therefore, even in the case of the oil supply nozzle 23 in which the nozzle tube tip is inserted into the liquid supply port of the fuel tank to be supplied and the operation lever is in the open state, the oil solution is not discharged from the nozzle tube tip and the fuel of the fueling vehicle Since the liquid level in the tank does not rise, the fuel vapor does not overflow from the liquid supply port to be supplied, and the increase in the concentration of fuel vapor in the vicinity of the liquid supply port can be suppressed to reduce the concentration due to diffusion.

  Therefore, as shown in FIG. 4B, the refueling work area 20P of the predetermined refueling machine 20-n can be separated from the charging work area 30P of the predetermined charger 30-m so as not to overlap. However, the refueling work area 20Ps including the refueling-side safety distance d1 overlaps the charging work area 30P and the charging work area 30Ps including the charging-side safety distance d2, or the charging work area including the charging-side safety distance d2. Even if 30Ps overlaps the fueling work area 20Ps including the fueling work area 20P and the fueling-side safety distance d1, the power supply to the charging target by the charger 30-m on the priority side is inferior ( Since fuel (oil liquid) is not discharged to the supply target by the non-priority side refueling machine 20-n at the same time, fuel vapor around the fuel supply device may permeate around the priority side charger. Can be prevented. For this reason, during the charging operation using the charger 30-m, the refueling machine 20-n cannot perform refueling. Therefore, the refueling work area 20Ps including the refueling side safety distance d1 of the subordinate refueling machine 20-n. Since the concentration of the fuel vapor is reduced, there is no possibility that the fuel vapor enters the vicinity of the charger during the charging operation.

  In the above-described fuel supply machine 20-n (n = 1 to 3) of the energy supply system 10, the operation lever is in an open state based on the prohibition of start of the fuel supply work or the suspension and stop of the fuel supply work. The description has been given of the configuration in which the discharge of the oil liquid from the nozzle 23 is stopped by stopping the driving of the pump of the liquid supply / measurement system 24. However, a control valve for distributing / blocking the oil liquid to the liquid supply / measurement system 24 is provided. In the fueling machine 20 provided, it can also be performed by closing the control valve.

  Next, the charger process executed by the charger 30-n with respect to the filler process executed by the filler 20-n described above will be described with reference to FIG.

  As shown in FIG. 8, similarly in the charger 30-m (each of m = 1 to 3) of the energy supply system 10, during the operation of the charger 30-n, the charging circuit 39 first starts the charging work start signal. Whether or not is input is monitored (SC110). In this case, the charging operation start signal is input to an operation input related to the start of the charging operation by an operator using the touch panel display 38, or to the charger 30-m including the charging control circuit (CCID) as in this embodiment. For example, the input of a preparation completion signal indicating that the charging target side is ready to receive the supply of charging electricity, which is supplied from the electric vehicle 9e to be charged by connection of the charging connector 35 to the charging outlet, corresponds. . The preparation completion signal is a charge control on the charging target side as a potential drop of the CPLT signal (control pilot signal) transmitted from the charger 30-n to notify the allowable current value (rated current) of the charging cable 34. The circuit supplies the charging control circuit of the charger 30-m. The CPLT signal is supplied to the charging cable 34 together with the power supply line, and the charging control circuit (CCID) provided in the charger 30-n and the grounding portion of the electric vehicle 9e are connected to the charging control circuit on the electric vehicle 9e side. It is transmitted on the control pilot signal line connected through the network.

  When the charging circuit 39 detects the input of the charging work start signal in step SC110, the charging circuit 39 transmits a charging work permission request (charging permission request) to the energy supply management device 11 connected in serial communication with the charger 30-m. (SC120). After the transmission, the charging circuit 39 waits to receive a charging work permission (charging permission) or charging work prohibition (charging prohibition) transmitted from the energy supply management device 11 to the charger 30-m in response to the permission request. (SC130, 140).

  When the charging circuit 39 receives the charging permission from the energy supply management device 11 in step SC130, the charging circuit 39 performs power supply control processing shown in steps SC150, 160, 170, 180, and 190. On the other hand, when the charging circuit 39 receives charging prohibition from the energy supply management device 11 in step SC140, the charging circuit 39 performs power supply start prohibiting processing shown in steps SC141 to SC147. In addition, the power supply start prohibition process shown in steps SC141 to SC147 is set in <Arrangement 3> such that the refueling work of the refueling machine 20-n has priority over the charging work by the charger 30-m. This is a process performed by the charging circuit 39 in the charger 30-m of the subordinate device when the refueling machine 20-n is already in a refueling operation.

  In this power supply control process, in this embodiment, the charging circuit 39 activates a relay for energizing / interrupting the power supply line of the charging cable 34 to the energized state in the charging control circuit (CCID). Supply of charging electricity to the charging connector 35, that is, energization to the charging connector 35 is started via the power supply line 34 (SC150). When the charging circuit 39 starts supplying charging electricity to the charging connector 35, the charging operation is started to the energy supply management device 11, and charging is performed indicating that the charger 30-m is in a charging operation state. A notification is sent (SC160).

  Thereby, in the charger 30-m, after energization to the charging connector 35 is started in step SC150, the rechargeable battery of the electric vehicle 9e to be charged is charged via the power supply line of the charging cable 34. Will be supplied. Therefore, charging electricity is supplied to the rechargeable battery of the electric vehicle 9e to which the charging connector 35 is connected.

  After transmitting the charging notification, the charging circuit 39 displays that the battery is being charged on the touch panel display 38, and inputs the charging end signal and the energy supply management device 11 while measuring the amount of charging electricity and the charging time. The reception of the charge prohibition transmitted from is monitored (SC170, 180). In this case, the charge end signal is an operation input related to the end of the charge operation by the operator using the touch panel display 38, or a set detection time elapse detection signal in the case of a charge operation for a preset charge time. In the charger 30-m equipped with the control circuit (CCID), the charger 30-m transmits the current allowable value (rated current) of the charging cable 34 to the electric vehicle 9e to be charged in order to notify it. This corresponds to a predetermined change in CPLT signal (control pilot signal) (return of potential drop) and the like.

  When the charging circuit 39 detects the input of the charging end signal in step SC170, the charging control circuit (CCID) operates the relay for energizing / cutting off the charging cable 34 to the cut-off state, and the charging started in step SC150. The energization of the connector 35 is stopped (SC190), a charge end notification is transmitted to the energy supply management device 11 (SC200), and the charger process related to the current charging operation is ended.

  On the other hand, when the charging circuit 39 receives charging prohibition from the energy supply management device 11 before the end of charging in step SC180, the charging circuit 39 performs power supply interruption / stop processing shown in steps SC181 to SC187.

  Here, the power supply start prohibition process shown in steps SC141 to 145 and the power supply interruption / stop process shown in steps SC181 to 187 will be described.

  In the power supply start prohibition process and the power supply interruption / stop process, the priority of the refueling work by the predetermined refueling machine 20-n is given to the interlock setting table 12 of the energy supply management device 11 with respect to the charging work by the charger 30-m. This is a subordinate process on the charger 30-m side when set. In either process, the charging circuit 39 of the charger 30-m performs the charging prohibition received from the energy supply management device 11 as a trigger.

  In the charging start prohibition process shown in steps SC141 to 145, when the charging circuit 39 receives the charging prohibition from the energy supply management device 11 in step SC140 in response to the transmission of the charging work permission request shown in step SC120, the charging circuit 39 The use failure indicating that the charging operation cannot be performed using the charger 30-m is notified by, for example, displaying it on the touch panel display 38 (SC141). Thereby, the operator who was trying to supply charging electricity to the charging target using the charger 30-m is the charger 30 in which the charger 30-m is waiting for priority (subordinated). In addition, there is a refueling work by a predetermined refueling machine 20-n that is currently working, which has priority over the charging work using this charger 30-m, and the charging work using the charger 30-m until it is finished. Can understand that can not start.

  After notifying that the charger 30-m cannot be used in step SC141, the charging circuit 39 monitors the reception of the charging permission transmitted from the energy supply management device 11 and the input of the charging end signal (SC143, 145). In this case, the charging end signal is an operation input related to the end of the charging operation by an operator using the touch panel display 38, or a charging connector storage detection signal from a connector detection switch that responds to storage of the charging connector 35 in the connector holding portion 36. This corresponds to the input.

  When the charging circuit 39 receives the charging permission from the energy supply management device 11 at step SC143, the charging circuit 39 refuels with a predetermined refueling machine 20-n which has priority over the charging work using the charger 30-m. Is completed, the power supply control process shown in steps SC150, 160, 170, 180, and 190 is performed, and the charging operation using the charger 30-m is started. On the other hand, when the input of the charging end signal is confirmed in step SC145, the charging end notification is transmitted to the energy supply management device 11 as the current charging operation using the charger 30-m is stopped ( SC200), the charger process related to the current charging operation is terminated.

  On the other hand, in the power supply interruption / stop processing shown in Steps SC181 to SC187, when the charging circuit 39 receives charging prohibition from the energy supply management device 11 in Step SC180, the charging circuit 39 stops energization to the charging connector 35 started in Step SC150. (SC181), a charging stop indicating that the charging work performed using the charger 30-m is interrupted or stopped is displayed on the touch panel display 38, for example (SC183).

  In this case, the energization stop to the charging connector 35 shown in step SC181 is performed by, for example, interrupting the relay of the charging control circuit in which the charging circuit 39 energizes and interrupts the charging cable 34 independently of the input of the charging end signal. Or by opening a switch provided in the power supply line on the upstream side of the charge control circuit or its relay.

  As a result, the operator who has supplied charging electricity to the charging target using the charger 30-m is informed of the charging work performed using the charger 30-m. A priority refueling operation is started, and the charger 30-m becomes a priority waiting (subordinate) charger 30-m, and the refueling device 20-n has a priority over the charging operation using this charger 30-m. It is possible to grasp that the charging work using the charger 30-m is interrupted until the refueling work is completed. In step SC181, energization to the charging cable 34 and the charging connector 35 is stopped, and the charging cable 34 and the charging connector 35 are disconnected from the power supply line on the upstream side of the relay of the charging control circuit, and the charging is performed. By preventing the current from flowing, it is possible to prevent the fuel vapor around the refueling device from entering the vicinity of the charging device during the charging operation.

  As a result, an operator who has been using this charger 30-m to charge the rechargeable battery of the electric vehicle is in charge of priority (subordinated) due to the charging stop notification. The charging work using the charger 30-m is suspended / stopped until the refueling work by the predetermined refueling machine 20-n newly started, which has priority over the charging work using 30-m, is completed. I can grasp it. Since the charging cable 34 and the charging connector 35 are cut off by the interruption / stopping of the charging operation even in the charging operation state after the start of energization of the charging connector 35 shown in steps SC150 and 160, the charging operation is performed. It is possible to prevent fuel vapor around the refueling device from entering the charging device.

  After notifying the charging stop of the charger 30-m in step SC183, the charging circuit 39 monitors the reception of the charging permission transmitted from the energy supply management device 11 and the input of the charging end signal (SC185, 187). In this case, the charging end signal is an operation input related to the end of the charging operation by an operator using the touch panel display 38, or a charging connector storage detection from a connector detection switch that responds to storage of the charging connector 35 in the connector holding portion 36. This applies to signal input.

  When the charging circuit 39 receives the charging permission from the energy supply management device 11 in step SC185, the charging circuit 39 refuels with a predetermined refueling machine 20-n that has priority over the charging work using the charger 30-m. Is completed, power supply control processing shown in steps SC150, 160, 170, 180, and 190 is performed, and the charging operation using the charger 30-m is automatically restarted. On the other hand, when the input of the charging end signal is confirmed in step SC187, the charging end notification is transmitted to the energy supply management apparatus 11 as the current charging operation using the charger 30-m is stopped ( SC200), the charger process related to the current charging operation is terminated.

  Thus, in the charger 30-m (each of m = 1 to 3) of the energy supply system 10, charging permission or charging prohibition supplied from the energy supply management device 11 in response to transmission of a charging work permission request is performed. In response to each reception, before the charging power supply to the charging cable 34 and the charging connector 35 is started, the start of the charging work is permitted or the start of the charging work is prohibited, and the charging power to the charging cable 34 and the charging connector 35 is charged. After the start of feeding, the charging operation can be interrupted / stopped or resumed. Therefore, even if the charging connector 35 is attached to the charging outlet to be charged and is in a charging operation state, the charging cable 34 and the charging connector 35 are connected to the upstream circuit connected to the original power source in the charging device. Since the power supply to the charging cable 34 and the charging connector 35 is stopped, the fuel vapor around the fueling device can be prevented from entering the vicinity of the charging device during the charging operation.

  Therefore, as shown in FIG. 4B, the refueling work area 20P of the predetermined refueling machine 20-n can be separated from the charging work area 30P of the predetermined charger 30-m so as not to overlap. However, the refueling work area 20Ps including the refueling-side safety distance d1 overlaps the charging work area 30P and the charging work area 30Ps including the charging-side safety distance d2, or the charging work area including the charging-side safety distance d2. Even when 30Ps overlaps with the fueling work area 20Ps and the fueling work area 20Ps including the fueling side safety distance d1, the fuel (oil) is being discharged to the supply target by the priority-side fueling machine 20-n. The charging of the subordinate side (non-priority side) charger 30-m is not performed at the same time, and the subordinate side charger is prohibited from starting charging work or interrupting / stopping charging work. It is in a state. As a result, while the fuel (oil liquid) is being discharged to the supply target by the priority-side refueling machine 20-n, energization to the charging connector 35 via the charging cable 34 is cut off, and the charging connector 35 is connected to the charging cable 34. Since the charging electricity itself is not supplied via this, the safety in the energy supply station 1 where the charging work area 30Ps and the refueling work area 20Ps described above overlap can be further enhanced.

  Next, in order to cause the refueling machine 20-n and the charger 30-n to execute the above-described refueling machine process and charger process, the refueling / charging execution management process (energy supply management process) executed by the energy supply management device 11 This will be described with reference to FIG.

  The energy supply management device 11 is provided with a keyboard, a display, etc. as an input / output unit, and includes a CPU, a memory (storage unit), an interface for communication and input / output, for example, a POS terminal for a gas station (sales point-of-sale information for a gas station) It is configured by a computer device such as a management machine 19.

  In the memory, the refueling work by each of the refueling machines 20-1 to 20-3 and the charger 30 between the refueling machines 20-1 to 20-3 and the respective chargers 30-1 to 30-3 are previously stored in the memory via the input / output unit. The work priority relationship with the charging work by each of -1 to 3 is set and stored as an interlock setting table 12 as shown in FIG. In the interlock setting table 12 shown in FIG. 6, since the charging operation time is generally longer than the refueling operation time, the charging operation area 30Ps is used for the charging operation using the chargers 30-1 to 30-3. However, even if the priority order of the two is reversed, the fueling work using each of the fueling machines 20-1 to 20-3, in which the fueling work area 20Ps overlaps, is given priority. Further, the superiority and inferiority of the refueling work and the charging work may be mixed for each area.

  The memory also includes a request for permission for refueling work (FIG. 7, SD120), a refueling notification (SD160), a refueling end notification (SD200), and a charger 30- transmitted from each of the refueling machines 20-1 to 20-3. 1 to 3 and a charger based on the reception of the charging permission request (FIG. 8, SC120), the charging notification (SC160), and the charging end notification (SC200) transmitted from each of For example, the device statuses of 30-1 to 30-3, such as waiting for work, executing work, and suspending work, are stored or erased, and each of the fuel dispensers 20-1 to 30-3 and the chargers 30-1 to 30-3 is stored. A device status management table 13 is also provided in which device status is updated and stored as needed.

  In the present embodiment, the energy supply management device 11 configured by a computer device is based on the storage information of the interlock setting table 12 and the device status management table 13 described above, and the energy supply system 10 of the energy supply station 1. Therefore, the refueling / charging execution management process (energy supply management process) as shown in FIG. 9 is executed.

  As shown in FIG. 9, in the energy supply system 10, the energy supply management device 11 performs initialization processing of the energy supply management device 11 itself and the entire energy supply system 10 based on an initialization instruction by turning on the power of the device. (SP100). This initialization processing includes reading of the interlock setting table 12 shown in FIG. 6 and initialization of the device status table 13. Here, in the initialization of the equipment status management table 13, each of the oil feeders 20-1 to 20-3 and the chargers 30-1 to 30-3 is set to a management initial state in which “waiting for work” is stored as the equipment status. As a result, the equipment status table 13 starts the refueling work and the charging work that have not been used for the refueling work and the charging work for each of the refueling machines 20-1 to 30 and the chargers 30-1 to 30-3. It is set and stored that the prepared work standby state is established.

  Then, the energy supply management device 11 is ready for execution management for the refueling work using the refueling machines 20-1 to 3 and the charging work using the chargers 30-1 to 30-3 shown in step SP100. Then, through the communication interface, at step SP200, any one of the refueling work permission requests (FIG. 7, SD120) transmitted from any of the refueling machines 20-1 to 20-3, or any of the chargers 30-1 to 30-3. In step SP300, a refueling notification (FIG. 7, SD160) transmitted from one of the refueling machines 20-1 to 3 at step SP300 as to whether or not the charging work permission request (FIG. 8, SC120) transmitted from is received. In addition, whether or not the during-charging notification (FIG. 8, SC160) transmitted from any of the chargers 30-1 to 30-3 has been received, and in any one of the refueling machines 20-1 to 20-3 in step SP400 Refueling end notification (Fig. 7, SD200) that has been sent and charger It is confirmed whether or not a charge end notification (FIG. 8, SC200) transmitted from any one of 30-1 to 30-3 has been received.

  In step SP200, when the energy supply management device 11 receives a work permission request such as a refueling work permission request from the refueling machine 20 or a charging work permission request from the charger 30, these work permission shown in step SP210 and below. When an energy supply control process is performed in response to the request, and a notification during operation such as a notification during refueling from the fuel filler 20 or a notification during charging from the charger 30 is received in step SP300, these notifications during operation shown in step SP310 The energy supply control process is performed in response to, and upon receiving a work end notification such as a refueling end notification from the refueling machine 20 or a charging end notification from the charger 30 in step SP400, these work end notifications shown in step SP410 and below The energy supply control process in response to is performed.

  First, the energy supply management device indicates a work permission request from the fueling machine 20 or the charger 30, which is composed of a request for permission of the fueling work from the fueling machine 20 or a request for permission of the charging work from the charger 30 shown in step SP 210 and the subsequent steps. The energy supply control process in response to the work permission request when 11 is received will be described.

  In this case, the energy supply management device 11 first acquires the device information of the transmission source from the received work permission request (SP210). When the received work permission request is a permission request for refueling work from the refueling machine 20, the energy supply management apparatus 11 is connected to the energy supply management apparatus 11 by communication from the received data. It can be identified which one of the fueling machines 20-1 to 20-3. Further, when the received work permission request is a request for permission of charging work from the charger 30, the charger 30-1 in which the charger 30 of the transmission source is connected to the energy supply management device 11 from the received data. -3 can be identified.

  Then, the energy supply management apparatus 11 uses the identified work permission request transmission source refueling machine 20-x (x is any one of 1 to 3) or the charger 30-x as shown in FIG. With reference to the lock setting table 12, the charger 30-y (y is any one of 1 to 3 excluding x) with priority given to the work for the refueling machine 20-x or the charger 30-x of the work permission request transmission source. ) Or the refueling machine 20-y is set, and the charger 30-x or the refueling machine 20-x itself as the work permission request transmission source becomes the subordinate device, or the charger 30- becomes the subordinate work. z (z is any one of 1 to 3 excluding x) or the refueling machine 20-z is set, and the refueling machine 20-x or the charger 30-x itself as the work permission request transmission source becomes the priority device. In addition, the charger 30-y or the refueling machine 20-y where work is prioritized, or charging where work is subordinate Check if 30-z or refueling machine 20-z is not set, and if the refueling machine 20-x or charger 30-x as the work permission request transmission source is an independent device unrelated to priority / subordinate (SP220).

  Further, the energy supply management device 11 confirms that the refueling machine 20-x (x is any one of 1 to 3) or the charger 30-x that is the work permission request transmission source is inferior based on the confirmation of the interlock setting table 12. If the device is a device, a priority device, or an independent device, and if the device itself is a priority device, device information of the subordinate device for the device is also acquired.

  Then, the energy supply management device 11 determines whether the refueling machine 20-x or the charger 30-x as the work permission request transmission source is a subordinate device, a priority device, or an independent device (SP230). 240), the following energy supply management process is performed.

  When the refueling machine 20-x or the charger 30-x as the work permission request transmission source is a priority device (SP230 “No”, SP240 “Yes”), the energy supply management device 11 stores the device status management table 13 Referring to this, it is confirmed whether or not the charger 30-z or the refueling machine 20-z, which is its own subordinate device, is in a work execution state such as refueling or charging (SP250). Then, the energy supply management device 11 has a charger 30-z or a refueling device 20-z that is its own subordinate device. z or refueling machine 20-z sends a work prohibition such as charging prohibition or refueling prohibition (SP251), and until then, the charger 30-z or refueling machine 20-z of this subordinate device is sent to the device status management table 13 until then. Instead of the stored work-in-execution state such as charging or refueling, a work-interrupting (work-in-progress stop) state such as stopping during charging or stopping during refueling is stored (SP253). Thereafter, the energy supply management device 11 transmits a work permission such as a refueling permission or a charging permission to the refueling machine 20-x or the charger 30-x as a work permission request transmission source (SP260).

  On the other hand, the energy supply management device 11 is the case where the refueling machine 20-x or the charger 30-x of the work permission request transmission source is an independent device (SP230 “No”, SP240 “Yes”) or its own subordinate device. When it is confirmed with reference to the device status management table 13 that a certain charger 30-z or refueling machine 20-z is in a work standby state in which charging work or refueling work is not performed (SP230 “No”) , SP240 “Yes”, SP250 “Yes”), the work permission such as refueling permission or charging permission is transmitted as it is to the refueling machine 20-x or the charger 30-x as the work permission request transmission source (SP260).

  In the case where the work permission request transmission source device is a priority device as described above, when the work permission request transmission source oiler 20-x or the charger 30-x is a subordinate device, the energy supply management device 11 Refers to the device status management table 13 and confirms whether or not the charger 30-z or the refueling machine 20-z having priority over itself is in a work execution state such as refueling or charging (SP270). . Then, the energy supply management device 11 performs work such that the charger 30-z or the fuel filler 20-z, which is the priority device of the fuel filler 20-x or the charger 30-x as the work permission request transmission source, is refueling or charging. If it is in the running state, a work prohibition such as a refueling prohibition or a charging prohibition is transmitted to the refueling machine 20-x or the charger 30-x as the work permission request transmission source (SP271), and the apparatus status management table 13 is transmitted. , Waiting for the refueling work that has been stored so far for the refueling machine 20-x or the charger 30-x of the work permission request transmission source that becomes a subordinate device of the charger 30-z or the refueling machine 20-z that is the priority device Alternatively, in place of the work waiting state such as waiting for the charging work, a work suspending state in which the start of the refueling work or the start of the charging work is prohibited is stored (SP273).

  On the other hand, in the confirmation shown in step SP270, even if the refueling machine 20-x or the charger 30-x that is the work permission request transmission source is a subordinate device, the charger 30-z or the refueling device that is the priority device. When 20-z is not in a state of performing work such as refueling or charging but in a state of waiting for work, the energy supply management device 11 supplies the refueling machine 20-x or the charger 30-x as a work permission request transmission source. Work permission such as refueling permission or charging permission is transmitted (SP280).

  As a result, in the energy supply control process in response to the work permission request from the refueling machine 20 or the charger 30 shown in step SP210 and after, the refueling machine 20-x or the charger 30-x as the work permission request transmission source has priority. In the case of a device or an independent device, the refueling work or charging work by the refueling machine 20-x or the charger 30-x as the work permission request transmission source can be started. At that time, the refueling machine 20-x or the charger 30-x that is the transmission source of the work permission request is a priority device, and the charger 30-z or the refueling machine 20 of the subordinate device that is in a work execution state such as charging or refueling. If -z is present, the refueling operation or charging operation by the charger 30-z or the refueling machine 20-z of these subordinate devices is interrupted, and the power supply or fuel supply is stopped.

  On the other hand, when the refueling machine 20-x or the charger 30-x as the work permission request transmission source is a subordinate device, the preferential charger 30-z or the refueling device 20-z is refueling or The refueling operation by the refueling machine 20-x or the charger 30-x of the work permission request transmission source or only during the standby state for the recharging work or for the refueling operation, not during the operation such as charging. Charging work can be started. However, when the charger 30-z or the refueling machine 20-z that is the priority device is performing a work such as refueling or charging, the refueling machine 20-x or the charger 30-x that is the work permission request transmission source. The refueling operation or charging operation is not started, and the fuel supply or power supply is not started.

  Next, the energy supply management device 11 receives an in-work notification from the refueling machine 20 or the charger 30, which includes a notification during refueling from the refueling machine 20 or a notification during charging from the charger 30, which is shown in step SP 310 and subsequent steps. The energy supply control process in response to the notification during work will be described.

  In this case, the energy supply management device 11 first acquires the device information of the transmission source from the received work notification (SP310). In the case where the received in-operation notification is a refueling notification from the refueling machine 20, the energy supply management apparatus 11 is connected to the energy supply management apparatus 11 from the received data. 20-1 to 20-3 can be identified. When the received notification of work is a notification of charging from the charger 30, the chargers 30-1 to 30-3 whose communication source is connected to the energy supply management device 11 from the received data. Can be identified.

  Then, the energy supply management device 11 waits for the refueling work stored until then in the device status management table 13 for the refueling machine 20-x or the charger 30-x that is the transmission source of the identified in-work notification. Instead of a work standby state such as a work standby state, or a work suspension state such as start prohibition or suspension of refueling work, or start prohibition or suspension of charging work, a work execution state such as refueling or charging is stored (SP320). .

  As a result, in the energy supply control process in response to the in-operation notification from the refueling machine 20 or the charger 30 shown in step SP310 and subsequent steps, the energy supply management device 11 receives the refueling permission from the refueling machine 20-x. By renewing the device status in the device status management table 13 based on reception of a notification during operation such as a notification during refueling or a notification during charging from the charger 30-x in response to the charging permission, the refueling machine 20-x or Device status management that the charger 30-x has received work permission and is in a work execution state in which refueling or power feeding is possible (SD150, 160 in FIG. 7 or SC150, 160 in FIG. 8). It can be grasped only by referring to the table 13.

  Finally, the energy supply management device 11 receives a work end notification from the fueling device 20 or the charger 30, which includes a refueling end notification from the fueling device 20 or a charging end notification from the charger 30, as shown in step SP 400 and subsequent steps. An energy supply control process in response to the work end notification in the case of having been performed will be described.

  In this case, the energy supply management device 11 first acquires the device information of the transmission source from the received work end notification (SP410). When the received work end notification is a refueling end notification from the fuel feeder 20, the energy supply management device 11 is connected to the energy supply management device 11 from the received data. 20-1 to 20-3 can be identified. Further, when the received work permission request is a charge end notification from the charger 30, the chargers 30-1 to 30-3 whose communication source is connected to the energy supply management device 11 from the received data. Can be identified.

  Then, the energy supply management device 11 uses the interfacing device shown in FIG. 6 based on the identified refueling machine 20-x (x is any one of 1 to 3) or the charger 30-x. With reference to the lock setting table 12, the charger 30-y (y is any one of 1 to 3 excluding x) with priority given to the work for the refueling machine 20-x or the charger 30-x of the work permission request transmission source. ) Or the refueling machine 20-y is set, and the charger 30-x or the refueling machine 20-x itself as the work permission request transmission source becomes the subordinate device, or the charger 30- becomes the subordinate work. z (z is any one of 1 to 3 excluding x) or the refueling machine 20-z is set, and the refueling machine 20-x or the charger 30-x itself as the work permission request transmission source becomes the priority device. In addition, the charger 30-y or the refueling machine 20-y where work is prioritized, or charging where work is subordinated Check if 30-z or refueling machine 20-z is not set, and if the refueling machine 20-x or charger 30-x as the work permission request transmission source is an independent device unrelated to priority / subordinate (SP420).

  Further, the energy supply management device 11 confirms that the refueling machine 20-x (x is any one of 1 to 3) or the charger 30-x that is the work permission request transmission source is inferior based on the confirmation of the interlock setting table 12. If the device is a device, a priority device, or an independent device, and if the device itself is a priority device, device information of the subordinate device for the device is also acquired.

  Then, the energy supply management device 11 determines whether the refueling machine 20-x or the charger 30-x as the work permission request transmission source is a priority device, a subordinate device, or an independent device (SP430, 440). The following energy supply management process is performed.

  When the refueling machine 20-x or the charger 30-x as the work end notification transmission source is a priority device (SP430 “Yes”), the energy supply management device 11 refers to the device status management table 13 and refers to itself. It is checked whether the charger 30-z or the refueling machine 20-z, which is a subordinate device, is in a work interruption state such as during refueling or charging (SP440). Then, the energy supply management device 11 is in a suspended state in which the charger 30-z, which is its subordinate device, prohibits or interrupts the start of charging work, or the refueling machine 20-z prohibits or interrupts the start of fueling work. In this case, work permission such as charging permission or refueling permission is transmitted to the charger 30-z or refueling machine 20-z of the subordinate device (SP450), and the charger 30 of this subordinate device is sent to the device status management table 13. -Z or the refueling machine 20-z deletes the work suspension state that has been stored until then, such as prohibition or interruption of charging work or prohibition or interruption of refueling work (SP460). In this case, the deletion of the work-suspended state is not limited to the blank state in which any of the work-suspended state, the work-waiting state, and the work-in-execution state is stored. In addition, storing a standby state such as waiting for charging work or waiting for refueling work is also included.

  Thereafter, the energy supply management device 11 is performing the operation of refueling or charging that has been stored in the device status management table 13 for the refueling machine 20-x or the charger 30-x that is the work end notification transmission source. The state is deleted (SP470). Note that in this case, the work in progress state is deleted not only by blanking in which none of the work suspension state, work standby state, and work execution state is stored, but in place of the work execution state. In addition, it also includes storing a work standby state such as charging standby or refueling standby.

  On the other hand, when the fuel dispenser 20-x or the charger 30-x itself as the work end notification transmission source is an independent device or a subordinate device (SP430 “No”), the energy supply management device 11 does not change the device. In the situation management table 13, for the refueling machine 20 -x or the charger 30 -x that is the work end notification transmission source, the work execution state such as during refueling or charging that has been stored so far, or the start or prohibition of charging work is prohibited or interrupted Or, the suspended state such as prohibition or suspension of refueling work is deleted (SP470). In this case, the deletion of the work in progress state or the work in progress state is not limited to a blank in which any of the work stop state, the work standby state, and the work execution state are not stored. It also includes storing a work standby state such as a charging work standby or a refueling standby, instead of the execution state or the work interruption state.

  Thereby, in the energy supply control process in response to the work end notification from the fuel filler 20 or the charger 30 shown in step SP410 and below, the fuel filler 20-x or the charger 30-x as the work end notification transmission source has priority. In the case of a device, the priority device is the subordinate device charger 30-z or the refueling device 20-z, which is the priority device, the work end notification transmission source refueling device 20-x or the charger 30-x. If the operation of the refueling machine 20-x or the charger 30-x is in a state where the work start is prohibited or the work is suspended, the charger 30-z of the subordinate device whose work start is prohibited or is suspended. It is possible to automatically restart the charging operation by the refueling and the refueling operation by the refueling machine 20-z.

  As described above, according to the energy supply system 10 according to the present embodiment, the distance D between the fueling work area 20P and the charging work area 30P is added to the fueling-side safety distance d1 and the charging-side safety distance d2. The energy supply management device 11 sets the work priority set in advance between the fueling device 20 and the charger 30 even between the fueling device 20 and the charger 30 that cannot be sufficiently separated from the total safety distance ds. In accordance with the relationship, during the fuel supply to the supply target by the charger 30 or the refueling machine 20 as the priority device or the power supply to the charge target, the power supply or the supply target to the charging target by the fuel supply device 20 or the charger 30 as the subordinate device The fuel supply is not started and is interrupted.

  As a result, the distance D between the refueling work area 20P and the charging work area 30P cannot be sufficiently separated from the total safe distance ds obtained by adding the refueling safety distance d1 and the charging safety distance d2. Between the battery charger 30 and the charger 30, the fuel supply from the fuel filler 20 and the power supply from the charging device are not performed simultaneously in parallel.

  Therefore, during power feeding to the charging target by the charger 30 which is the priority device, the fuel supply to the supply target from the refueling device 20 which is the subordinate device is not started, and is supplied by being interrupted. Since the fuel vapor does not overflow from the target liquid supply port as the liquid level in the fuel tank rises, the increase in the concentration of fuel vapor around the liquid supply port can be suppressed to reduce the concentration due to diffusion. It is possible to prevent the fuel vapor around the refueling device from entering the vicinity of the charging device during the work.

  Similarly, during the fuel supply to the supply target by the refueling machine 20 that is the priority device, the power supply to the charge target from the charger 30 that is the subordinate device is not started and is suspended, Since the charging cable 34 and the charging connector 35 are de-energized, the charging cable 34 and the charging connector 35 are disconnected from the power supply line on the source power source side, and charging electricity is not supplied at all. It is possible to prevent fuel vapor around the refueling device from entering the charging device.

  As a result, as shown in FIG. 4B, the refueling work area 20P and the charging work area 30P are overlapped due to restrictions on the expansion of the site and the arrangement of facilities and facilities such as the fuel supply device in the site. Even if they can be separated so as not to be separated, even if they cannot be separated sufficiently beyond the total safe distance ds, it becomes possible to arrange the oil feeder 20 and the charger 30 side by side and supply energy. In the station 1, flexibility can be given to the arrangement of facilities and facilities including the refueling machine 20 and the charger 30 in the site, and the reduction of the work efficiency of the fuel supply work can also be suppressed.

  In addition, even if the fuel supply to the supply target by the refueling device 20 that is a subordinate device or the power supply to the charging target by the charger 30 is interrupted and stopped by the charging operation by the charger 30 that is the priority device or the refueling operation by the refueling device 20 When the charging or refueling work by this priority device is completed, the fuel supply or power supply by the suspended subordinated device is automatically restarted, so the work of fuel supply work and charging work should be reduced. Can do.

  Further, in the energy supply system 10 according to the present embodiment, the above-described refueling / charging execution management process by the energy supply management device 11 as shown in FIG. 9 is performed on the ground-installed refueling machine as shown in FIG. The application is not limited only to the relationship between the refueling work area 20 and the charging work area by the ground-mounted charger 30. For example, even when the fueling machine 20 and the charger 30 are the fueling nozzle 23 and the charging connector 35 are the suspension type fueling machine 20 and the charger 30 suspended from the height of the energy supply station 1, The present invention is applicable even when one of the chargers 30 is a ground installation type and the other of the fuel filler 20 and the charger 30 is a suspension type.

  FIG. 10 is a configuration diagram of an embodiment of an energy supply system in a case where the fueling machine is a ground installation type and the charger is a suspension type.

  In the example shown in the figure, the charger 30 is connected to the charging connector 35 at the tip from the delivery unit 40 installed at a higher position than the height position of the fuel vapor staying in the vicinity of the fueling device during refueling in the energy supply station 1. The charging cable 34 provided with is extended by driving of the charging connector lifting mechanism 41, and is a suspended charger 30 suspended so as to be wound up.

As described above, the charger 30 is provided at a higher position than the height position of the fuel vapor staying around the refueling device during refueling, so that the fuel vapor around the fuel supply device may flow around the charging device. Can be reduced, and safety is improved.
When the charging connector raising / lowering mechanism 41 starts charging by the energy supply management device 11, the charging connector 34 extends the charging cable 34 so that the charging connector 35 is positioned to a chargeable height, and when charging by the charger is completed. First, the charging cable 34 is wound up to the predetermined height position of the charging connector 35.

  For this reason, since the charging connector 35 is located at a high place during non-charging, the possibility that the fuel vapor around the fuel supply device flows into the periphery of the charging device can be reduced, and the safety is improved. In addition, the supply connector efficiency is improved because the charging connector 35 does not get in the way when the vehicle moves during refueling.

  In addition, the ground-installed refueling machine 20 is provided on the front side and the back side of the refueling machine housing 21 with respect to the different fuel-driven vehicles 9f-1 and 9f-2 depending on the refueling nozzles 23-1 and 23-2. It is possible to perform the refueling work independently.

  Thus, the embodiment of the energy supply system according to the present invention is not limited to the embodiment described above, and the energy supply management device 11 is preset between the fuel filler 20 and the charger 30. In accordance with the work priority relationship, during the fuel supply to the supply target by the charger 30 or the refueling machine 20 as the priority device or the power supply to the charge target, the power supply to the charging target by the refueling device 20 or the charger 30 as the subordinate device or Various embodiments are possible as long as the fuel supply to the supply target is not started and interrupted.

  The charger 30 is a suspended charger 30 provided at a high place in the energy supply station 1. However, the charger 30 is not limited to this, and from the ground when the fuel vapor flowing out from the fuel filler 20 stays on the ground. It is sufficient that the charger 30 is provided at a higher position than the height position of the battery. Therefore, for example, as shown by a dotted line in FIG. is there.

  In the present embodiment, energy supply management, refueling control, and charging control are processed separately, but not limited thereto, for example, the energy supply management and charging control are managed by the refueling control device, The fuel supply control and charge control may be managed by the energy supply management device, or the energy supply management and fuel supply control management may be performed by the charge control device.

  In the above-described embodiment, by providing an air curtain around the charging device to generate an air flow downward from above, air flow from the outside to the charging device is blocked. Fuel vapor can be prevented from entering the periphery of the charging device, and safety is improved.
