[0057] FIG. 8 shows a state after an operation from FIG. 7, in which a request to connect the connector (first connection portion 55) of the charge / discharge device 5 to the vehicle (mobile object 6) is displayed. FIG. 9 shows a state after an operation from FIG. 8, in which a screen requesting access for the authentication process described as step S101 of the charge / discharge start process is displayed. FIG. 10 shows a state after an operation from FIG. 9, in which a screen for requesting and inputting the target charge amount described as steps S102 to S103 of the charge / discharge start process is displayed. In the screen illustrated in FIG. 10, the target charge amount is input as points. FIG. 11 shows a state after an operation from FIG. 10, in which a screen for inputting and instructing (confirming) the target charge amount described as steps S103 to S104 of the charge / discharge start process is displayed. The operator inputs the target charge amount as points and performs an input specifying the display of "Register" at the bottom right of the screen, thereby transmitting the input target charge amount. The software program for charging and discharging may be downloaded to the communication terminal device 8 and executed there, or may be executed within a server computer on the communication network NW and have the communication terminal device 8 display a screen related to the execution.

[0058] In this manner, the charge / discharge start process of the communication terminal device 8 is executed.

[0059] Fig. 12 is a flowchart showing an example of the charge / discharge start process of the charge / discharge control device 1 used in the charge / discharge control system disclosed in the present application. The charge / discharge start process described with reference to Fig. 12 is a process executed by the charge / discharge control device 1 in response to a request from the charge / discharge start process of the communication terminal device 8. The charge / discharge control device 1 executes the charge / discharge start process by causing the control unit 10 to execute various procedures defined in the charge / discharge control program 110 stored in the storage unit 11.

[0060] The control unit 10 of the charge / discharge control device 1 performs authentication processing in response to access from the communication terminal device 8 (S201), requests input of a target charge amount (S202), acquires the target charge amount transmitted from the communication terminal device 8 (S203), and stores the acquired target charge amount (S204). The target charge amount stored in step S204 is stored in, for example, a management database DB.

[0061] Furthermore, the control unit 10 determines whether the target charge amount is equal to or greater than the remaining point (S205), and if it determines that the target charge amount is equal to or greater than the remaining point (S205: YES), it starts charge / discharge control (S206). If it determines in step S205 that the target charge amount is less than the remaining point (S205: NO), it performs a predetermined abnormality process that requests re-input of the target charge amount (S206), and ends the process. The series of processes from steps S201 to S206 is executed in cooperation with the communication terminal device 8. Therefore, it is possible to appropriately configure the process so that part of the process, for example, the comparison process in step S205, etc., is executed by the charge / discharge app of the communication terminal device 8.

[0062] When the charge / discharge start process is executed, the charge / discharge device 5 reads various information such as the remaining charge, battery SOC, chargeable capacity, and dischargeable capacity from the connected mobile object 6, and stores the read information in the management database DB. The process of storing the various information in the management database DB is executed by the process of the information processing device 7. It is also possible to configure the information processing device 7 to execute part or all of the process of the charge / discharge device 5 described above.

[0063] In this manner, the charge / discharge start process of the charge / discharge control device 1 is executed.

[0064] 13 is a flowchart showing an example of the charge / discharge process of the charge / discharge control device 1 used in the charge / discharge control system disclosed in the present application. The charge / discharge control device 1 executes the charge / discharge control process to control the charging / discharging of each mobile object 6 connected to the charge / discharge device 5. The mobile object 6 for which charging / discharging is started by the above-mentioned charge / discharge start process is added to the targets of the charge / discharge control process. The charge / discharge control device 1 executes the charge / discharge control process by causing the control unit 10 to execute various procedures defined in the charge / discharge control program 110.

[0065] The control unit 10 of the charge / discharge control device 1 determines whether the measurement period has elapsed (S301). The charge / discharge control process controls charge / discharge at a preset measurement period of, for example, five minutes. If the control unit 10 determines in step S301 that the measurement period has elapsed (S301: YES), the control unit 10 acquires a received power value (S302). The received power value acquired in step 302 is a value indicating the power received from the power supply facility 2 measured by the power reception measurement unit 31 of the power receiving facility 3. As the received power value, various values ​​are used, such as an instantaneous value of power, an integrated value of power over a predetermined period (power amount), or other alternative values ​​related to power.

[0066] In step S301, if it is determined that the measurement period has not elapsed (S301: NO), the control unit 10 repeats the process of step S301.

[0067] After acquiring the received power value, the control unit 10 acquires points (S303), a guaranteed charge amount (S304), a target charge amount (S305), a remaining charge amount (S306), an integrated energy amount (S307), and an SOC value (S308). In steps S303 to S308, the control unit 10 accesses the management database DB to acquire information such as points, a guaranteed charge amount, a target charge amount, a remaining charge amount, an integrated energy amount, and an SOC value related to the mobile unit 6 that is to start charging or discharging a new battery due to the charge / discharge control start process and the user of the mobile unit 6. The guaranteed charge amount acquired in step S304 is the amount of charge guaranteed for the mobile unit 6 and is calculated, for example, from the commuting distance and the electricity cost. Specifically, the guaranteed charge amount is calculated by calculating the amount of energy required for a one-way commute from the commuting distance and the electricity cost, and is calculated as three times the amount of energy required for the one-way commute. The value three times the one-way distance is the amount of electricity required for commuting round trip, taking into account allowances for stops along the way, etc. That is, in step S304, the control unit 10 obtains the commuting distance and electricity cost, and calculates the guaranteed charging amount from the obtained commuting distance, thereby obtaining the guaranteed charging amount. As described above, the processing of steps S303 to S306 is processing for obtaining various information for each mobile object 6.

[0068] The processes of steps S302 to S308 or S303 to S308 described above may be configured to be executed in parallel as subroutines by the charge / discharge control device 1, and various information acquired in the subroutines may be stored in the storage unit 11. In this case, the charge / discharge control device 1 acquires various information from the storage unit 11 during the process of executing the charge / discharge process and executes the information as an alternative process to the above steps. The processes of steps S302 to S308 may also be executed by the information processing device 7. Specifically, the information processing device 7 executes processes corresponding to steps S302 to S308 at predetermined time intervals and stores the results in the storage unit 71. In this case, the charge / discharge control device 1 accesses the information processing device 7 during the process of executing the charge / discharge process, acquires various stored information, and executes the information as an alternative process to steps S302 to S308.

[0069] The control unit 10 determines whether the current operation mode is the charge mode or the discharge mode (S309). In step S309, the charge mode is an operation mode in which power received from the power supply facility 2 is supplied to the mobile object 6 connected to the charging / discharging device 5, and the power storage device 60 of the mobile object 6 is charged. The discharge mode is an operation mode in which the power storage device 60 is discharged and supplied to the power load equipment 4. The operation mode is determined by referring to information stored in the management database DB.

[0070] If it is determined in step S309 that the mode is the charge mode (S309: YES), the control unit 10 executes the charge mode process (S400). If it is determined that the mode is the discharge mode (S309: NO), the control unit 10 executes the discharge mode process (S500). After executing the charge mode process of step S400 or the discharge mode process of step S500, the control unit 10 returns to step S301 and repeats the subsequent processes.

[0071] The charge mode process executed in step S400 will be described. FIG. 14 is a flowchart showing an example of the charge mode process of the charge / discharge control device 1 used in the charge / discharge control system disclosed herein. FIG. 14 shows the charge mode process executed in step S400 of the charge / discharge process. As the charge mode process, the control unit 10 of the charge / discharge control device 1 determines whether the acquired received power is smaller than a preset charge stop threshold (S401). The charge stop threshold is a threshold for determining whether to reduce the number of mobile objects 6 to be charged or stop the charge mode in order to suppress the increase in received power when the received power from the power supply facility 2 increases. The charge stop threshold is set, for example, by the management terminal device 9 and stored in the memory unit 11 of the charge / discharge control device 1.

[0072] In step S401, when it is determined that the received power is smaller than the charge stop threshold (S401: YES), the control unit 10 calculates the amount of power that can be used to charge the mobile object 6 as the available power (S402). When the received power is smaller than the charge stop threshold, it is determined that there is a surplus power, and the charge / discharge control device 1 calculates the power equivalent to the surplus power, for example, the difference between the charge stop threshold and the received power, as the available power in the process of step S402.

[0073] The control unit 10 calculates the number of vehicles to start charging, which indicates the number of vehicles 6 that can start charging, based on the result of dividing the available power by a unit charging amount per vehicle that is set in advance (S403).

[0074] The control unit 10 calculates the number of chargeable vehicles 6, which indicates the number of vehicles 6 that can be charged (S404). The calculation in step S404 after calculating the number of vehicles that have started charging is, for example, a process of calculating the number of chargeable vehicles based on the result of adding the number of vehicles 6 that are currently charging to the number of vehicles that have started charging calculated in step S403.

[0075] The control unit 10 derives the priority order of the mobile objects 6 to be charged from among the mobile objects 6 connected to the charging / discharging device 5 (S405).

[0076] An example of a method for deriving the priority in step S405 will be described. The control unit 10 sorts the mobile units 6 in ascending order, using the value obtained by subtracting the guaranteed charge amount from the current remaining charge amount as the first key with the highest priority. The control unit 10 also sorts the mobile units 6 in descending order, using the value obtained by subtracting the integrated power amount from the target charge amount as the second key with the next highest priority after the first key. The control unit 10 also sorts the mobile units 6 in ascending order, using the SOC value of each mobile unit 6 as the third key with the next highest priority after the second key. The control unit 10 also sorts the mobile units 6 in ascending order, using the management number as the fourth key with the lowest priority. The management number may be set as data for items such as a user ID, a link ID, or various other arbitrary data, as appropriate. The control unit 10 derives the priority of the mobile units 6 using the setting examples described above.

[0077] By using the difference between the remaining charge and the guaranteed charge amount as the first key, the first priority is given to ensuring the guaranteed charge amount, i.e., the charge amount required for commuting, for the mobile unit 6. By using the difference between the target charge amount and the accumulated power amount as the second key, the second priority is given to ensuring the target charge amount entered by the user.

[0078] The control unit 10 rearranges the mobile objects 6 connected to the charging / discharging device 5 based on the derived priority, and selects the mobile objects 6 with the highest priority, up to the number of mobile objects that can be charged, as the mobile objects to be charged (S406).

[0079] The control unit 10 selects, among the moving objects 6 being charged, any moving object 6 that is not included in the selected moving objects to be charged as a moving object to be stopped from being charged (S407).

[0080] Based on the selection results of steps S406 and S407, the control unit 10 transmits commands such as a command to continue charging, a command to start charging, or a command to stop charging to each charging / discharging device 5 (S408), and returns to step S301 of the charging / discharging start process to repeat the subsequent processes. Each charging / discharging device 5 that has received the command performs processing to continue, start, or stop charging for the connected mobile object 6.

[0081] In step S401, when it is determined that the received power is equal to or greater than the charging stop threshold (S401: NO), the control unit 10 derives a reduction power indicating an amount of reduction in the power charged to the mobile object 6 (S409). When the received power value is equal to or greater than the charging stop threshold, the control unit 10 derives a reduction amount to reduce the received power value. The reduction amount is, for example, an excess power amount equivalent to the received power value exceeding the charging stop threshold.

[0082] The control unit 10 derives the number of vehicles 6 for which charging should be stopped, which indicates the number of vehicles 6 for which charging should be stopped, based on the derived reduced power consumption (S410). In step S410, for example, the control unit 10 derives the number of vehicles for which charging should be stopped by dividing the reduced power consumption equivalent to the excess power consumption by a preset unit charging amount per vehicle.

[0083] The control unit 10 determines whether the number of vehicles currently being charged is smaller than the derived number of vehicles whose charging has been stopped (S411).

[0084] If it is determined in step S411 that the number of vehicles currently charging is smaller than the number of vehicles currently charging that have stopped (S411: YES), the control unit 10 transmits a command to each charging / discharging device 5 to stop charging (S412). Then, the control unit 10 changes the operation mode to the discharging mode (S413), returns to step S301 of the charge / discharge start process, and repeats the subsequent processes. Steps S411 to S413 are processes in which, if the number of vehicles currently charging is smaller than the number of vehicles currently charging that have stopped, all charging is stopped and power is discharged from the power storage devices 60 of the mobile objects 6, thereby supplementing the power supplied to the power load equipment 4 and suppressing the power received from the power supply facility 2. Note that when the process is switched to the discharging mode and returns to step S301, discharging is not started at least for the period of the first measurement cycle, and therefore, the process is in a neutral mode in which no charging or discharging is actually performed during that period. The charge / discharge control system disclosed in the present application does not switch from charge mode to discharge mode instantly, but passes through a neutral mode, thereby making it possible to mitigate the electrical shock caused by switching.

[0085] In step S411, if it is determined that the number of vehicles currently being charged is equal to or greater than the number of vehicles currently not being charged (S411: NO), the control unit 10 proceeds to step S404, derives the number of vehicles 6 that can be charged (S404), and executes the subsequent processes. The derivation in step S404 after deriving the number of vehicles currently not being charged is, for example, a process of calculating the number of vehicles that can be charged based on the result of subtracting the number of vehicles currently not being charged calculated in step S410.

[0086] In this manner, the charging mode process is executed.

[0087] The discharge mode executed in step S500 will be described. FIG. 15 is a block diagram showing an example of the discharge mode process of the charge / discharge control device 1 used in the charge / discharge control system disclosed herein. FIG. 15 shows the discharge mode process executed in step S500 of the charge / discharge process. As the discharge mode process, the control unit 10 of the charge / discharge control device 1 determines whether the acquired received power is smaller than a preset discharge start threshold (S501). The discharge start threshold is a threshold for determining whether to start or continue discharging in order to suppress an increase in received power when the received power from the power supply facility 2 increases. The discharge start threshold is set, for example, by the management terminal device 9 to a value higher than the charge stop threshold, and is stored in the memory unit 11 of the charge / discharge control device 1.

[0088] In step S501, when it is determined that the received power is equal to or greater than the discharge start threshold (S501: NO), the control unit 10 calculates the amount of power at which new discharge should be started from the mobile object 6 as the discharge start power (S502). When the received power is equal to or greater than the discharge start threshold, it is determined that the received power should be reduced due to the start or increase of discharge from the mobile object 6, and the charge / discharge control device 1 calculates the discharge to be started or increased, for example, the difference between the received power and the discharge start threshold.

[0089] The control unit 10 calculates the discharge start number, which indicates the number of mobile bodies 6 that need to start discharging anew, based on the result of dividing the discharge start power by a unit discharge amount per vehicle that is set in advance (S503).

[0090] The control unit 10 derives the ideal number of units to discharge, which is the calculated number of units required to reduce the received power value, including the number of mobile objects 6 currently discharging, based on the result of dividing the sum of the discharge amount currently being discharged and the discharge start power by the unit discharge amount (S505). The ideal number of units to discharge derived in step S505 is a calculated number and does not necessarily match the number of units that can be discharged.

[0091] The control unit 10 derives the priority order of the mobile objects 6 to be discharged from among the mobile objects 6 connected to the charging / discharging device 5 (S506).

[0092] An example of a method for deriving the priority in step S506 will be described. The control unit 10 sorts the moving objects 6 in descending order, using the first key as the highest priority, which is the value obtained by subtracting the guaranteed charge amount from the current remaining charge amount. The control unit 10 also sorts the moving objects 6 in ascending order, using the second key as the value obtained by subtracting the integrated power amount from the target charge amount of each moving object 6 as the second key, which is the next highest priority after the first key. The control unit 10 also sorts the moving objects 6 in descending order, using the SOC value of each moving object 6 as the third key, which is the next highest priority after the second key. The control unit 10 also sorts the moving objects 6 in ascending order, using the management number as the fourth key, which is the lowest priority. Note that in order to prevent a moving object 6 belonging to a specific group from being selected as a discharging target, the priority may be adjusted so that the number of discharging target moving objects 6 is balanced between groups, while prioritizing the first and second keys.

[0093] By using the difference between the remaining charge and the guaranteed charge amount as the first key, the first priority is given to ensuring the guaranteed charge amount, i.e., the charge amount required for commuting, for the mobile unit 6. By using the difference between the target charge amount and the accumulated power amount as the second key, the second priority is given to ensuring the target charge amount entered by the user.

[0094] The control unit 10 derives the number of mobile objects 6 that can discharge (S507). The number of mobile objects 6 that can discharge is derived based on the number of mobile objects 6 that can discharge, such as mobile objects 6 whose current remaining charge amount is greater than the guaranteed charge amount, mobile objects 6 whose accumulated power amount exceeds the target charge amount, etc.

[0095] The control unit 10 compares the ideal number of units to be discharged calculated in step S505 with the number of units that can be discharged calculated in step S507, and determines whether the ideal number of units to be discharged is greater than the number of units that can be discharged (S508).

[0096] In step S508, if it is determined that the ideal number of units to be discharged is greater than the number of units that can be discharged (S508: YES), the control unit 10 sets the number of units that can be discharged as the number of units to be discharged (S509).In addition, in step S508, if it is determined that the ideal number of units to be discharged is equal to or less than the number of units that can be discharged (S508: NO), the control unit 10 sets the ideal number of units to be discharged as the number of units to be discharged (S510).

[0097] The control unit 10 rearranges the mobile bodies 6 connected to the charging / discharging device 5 based on the derived priority, and selects the mobile bodies 6 with the highest priority, up to the number of mobile bodies that can be discharged, as the mobile bodies to be discharged (S511).

[0098] The control unit 10 selects, among the discharging moving bodies 6, any moving body 6 that is not included in the selected discharging target moving bodies, as a discharging stop moving body (S512).

[0099] Based on the selection results of steps S511 and S512, the control unit 10 transmits commands such as a command to continue discharging, a command to start discharging, or a command to stop discharging to each charging / discharging device 5 (S513), and returns to step S301 of the charging / discharging start process to repeat the subsequent processes. Each charging / discharging device 5 that has received the command performs a process to continue, start, or stop discharging on the connected mobile object 6.

[0100] In step S501, if it is determined that the received power is less than the discharge start threshold (S501: YES), the control unit 10 determines whether the received power is less than a preset discharge stop threshold (S514). The discharge stop threshold is a threshold for determining whether or not it is necessary to stop or reduce discharge. The discharge stop threshold is set, for example, by the management terminal device 9 as a value lower than the charge stop threshold, and is stored in the memory unit 11 of the charge / discharge control device 1.

[0101] If it is determined in step S514 that the received power is smaller than the discharge stop threshold (S514: YES), the control unit 10 derives a discharge stop power indicating the amount of reduction in power discharged from the mobile object 6 (S515). When the received power value is smaller than the discharge stop threshold, the control unit 10 calculates the amount of power at which discharge is stopped in order to reduce the amount of discharge. The discharge stop power is derived, for example, as the amount of excess discharge power equivalent to the received power value that is below the discharge stop threshold.

[0102] The control unit 10 derives the number of mobile objects 6 at which discharge should be stopped, indicating the number of mobile objects 6 at which discharge should be stopped, based on the derived discharge stop power (S516). In step S516, for example, the control unit 10 derives the number of mobile objects 6 at which discharge should be stopped by dividing the discharge stop power corresponding to the excess discharge power amount by a preset unit discharge amount per mobile object.

[0103] The control unit 10 determines whether the number of units currently discharging is smaller than the calculated number of units to stop discharging (S517).

[0104] If it is determined in step S517 that the number of discharging devices is smaller than the calculated number of devices to stop discharging (S517: YES), the control unit 10 transmits a command to each charging / discharging device 5 to stop discharging (S518). Then, the control unit 10 changes the operation mode to charging mode (S519), returns to step S301 of the charge / discharge start process, and repeats the subsequent processes. Steps S517 to S519 are processes for stopping all discharging and switching to charging mode when the number of discharging devices is smaller than the number of devices to stop discharging. Note that after switching to charging mode and returning to step S301, charging is not started for at least the first measurement period, so that the system is essentially in neutral mode during that period. The charge / discharge control system disclosed herein can mitigate electrical shocks caused by switching by passing through neutral mode rather than instantaneously switching from discharging mode to charging mode.

[0105] In step S514, if it is determined that the received power is equal to or greater than the discharge stop threshold (S514: NO), the control unit 10 returns to step S301 of the charge / discharge start processing while maintaining the discharge state of the mobile object 6 connected to the charge / discharge device 5, and repeats the subsequent processing.

[0106] In step S517, if it is determined that the number of units discharging is equal to or greater than the number of units to be stopped from discharging (S517: NO), the control unit 10 proceeds to step S506 and executes the subsequent processes. After deriving the number of units to be stopped from discharging, the number of units that can be discharged in step S507 is derived, for example, taking into account the number of units to be stopped from discharging derived in step S516.

[0107] In this manner, the discharge mode process is carried out.

[0108] The charge / discharge process ends when the user operates the communication terminal device 8 or the charge / discharge device 5 and further disconnects the mobile object 6 from the charge / discharge device 5. Fig. 16 is a flowchart showing an example of the charge / discharge end process of the charge / discharge control device 1 used in the charge / discharge control system disclosed in the present application. The control unit 10 of the charge / discharge control device 1 detects an event such as an operation accepted by the communication terminal device 8 or the charge / discharge device 5 or disconnection of the mobile object 6 from the charge / discharge device 5 as the end of charge / discharge (S601).

[0109] Upon detecting the completion of charging / discharging, the control unit 10 performs processing to terminate charging / discharging for the mobile object 6 (S602). The control unit 10 tallies the accumulated amount of charging / discharging (S603), and adds or subtracts points (points) from the remaining points for the mobile object 6 based on the tallied result (S604). The control unit 10 then transmits the results of steps S603 to S604 as the charging / discharging result to a predetermined device such as the charging / discharging device 5, the communication terminal device 8, the management terminal device 9, or the management database DB (S606). The user can confirm the charging / discharging result as an image displayed on the display unit 52 of the charging / discharging device 5 or the display unit 84 of the communication terminal device 8. The management database DB updates its stored contents based on the charging / discharging result.

[0110] In step S604, for example, the charge / discharge control device 1 performs addition / subtraction such as subtracting remaining points by charging and adding remaining points by discharging. For example, when a mobile object 6 such as a vehicle is used for commuting, the charge / discharge control system disclosed in the present application can be operated to provide distribution points each month as a commuting allowance according to the commuting distance and the number of commuting days.

[0111] In this manner, the charge / discharge termination process is executed.

[0112] As described above in detail, the charge / discharge control system disclosed herein executes charge / discharge processing including various processes such as charge mode processing and discharge mode processing. That is, the charge / discharge control system acquires a received power value indicating the power received by the power receiving facility 3 from the power supply facility 2, derives the number of mobile objects 6 to be charged / discharged via the charge / discharge device 5 based on the acquired received power value, and derives a priority order for the mobile objects 6 to be charged / discharged based on the derived number. Then, the charge / discharge control system controls charging / discharging of the mobile objects 6 based on the derived priority order. Furthermore, when deriving the priority order, the charge / discharge control system takes into account values ​​such as the guaranteed charge amount, the remaining charge amount, the integrated power amount, and the target charge amount.

[0113] The above-described exemplary configuration allows the charge / discharge control system disclosed herein to provide excellent advantages, such as the ability to individually control the charging and discharging of multiple mobile objects 6 according to the status of each mobile object 6. Specifically, the charge / discharge control system disclosed herein provides excellent advantages, such as the ability to prioritize the mobile objects 6 that have the capacity to charge and discharge by prioritizing the mobile objects 6 that are to be charged and discharged. Furthermore, the charge / discharge control system disclosed herein provides excellent advantages, such as the ability to set a guaranteed charge amount to ensure that charging and discharging are performed to a degree that does not interfere with commuting, for example, ensuring the remaining charge necessary for traveling a distance three times the commuting distance. Furthermore, the charge / discharge control system disclosed herein provides excellent advantages, such as the ability to allow a user to input a target charge amount and perform charging and discharging according to the user's convenience, for example, ensuring the remaining charge necessary for a detour on the way home. Furthermore, the charge / discharge control system disclosed herein has excellent advantages, such as the ability to reduce the burden of sudden switching because it passes through a substantially neutral mode during the measurement cycle when switching between the charge mode and the discharge mode. Furthermore, the charge / discharge control system disclosed herein has excellent advantages, such as the ability to manage the exchange of power at points by setting a target charge amount using points.

[0114] The present invention is not limited to the above-described embodiments, but can be embodied in various other forms. Therefore, these embodiments are merely illustrative in all respects and should not be interpreted as limiting. The scope of the present invention is defined by the claims and is not limited in any way by the text of the specification. Furthermore, all modifications and variations that fall within the equivalent range of the claims are within the scope of the present invention.

[0115] For example, in the above embodiment, all charging / discharging devices are capable of charging and discharging mobile objects. However, the present invention is not limited to this. Various configurations are possible, such as configuring some or all of the charging / discharging devices 5 to be dedicated to charging based on device restrictions or contracts. In such a configuration, the charging / discharging control system disclosed herein acquires a received power value indicating the power received by the power receiving facility 3 from the power supply facility 2, and based on the acquired received power value, calculates the number of mobile objects 6 to be charged via charging devices that are dedicated charging / discharging devices 5, and performs control to derive a priority order for the mobile objects 6 to be charged based on the calculated number. In such a configuration, the specific procedure for deriving the priority order is a modification of the above embodiment.

[0116] For example, in the above embodiment, the charge / discharge control device 1 performs various processes, but the charge / discharge control system disclosed in the present application is not limited to this and various system configurations are possible. For example, the charge / discharge control system disclosed in the present application may be developed into various forms, such as the management terminal device 9 being responsible for some of the processes shown as the processes of the charge / discharge control system, or the charge / discharge control device 1 being composed of multiple devices, with each device sharing the processes and taking on some of the functions.
