[0003] [Patent Document 1] JP 2020-047018 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in Patent Document 1, the electricity usage plan of the private lodging facility is simply selected based on the user's electricity usage pattern, and it is difficult for the user to clearly feel the benefits of using the private lodging facility. For this reason, it is considered difficult to promote the use of private lodging facilities. Therefore, it is desirable to increase the number of users of accommodation facilities by promoting the use of accommodation facilities.

[0005] The present disclosure has been made to solve the above-mentioned problems, and its purpose is to provide a power management device and a power management system that can increase the number of users of accommodation facilities by promoting their use. [Means for solving the problem]

[0006] A power management device according to a first aspect of the present disclosure is a power management device that acquires information regarding the power status of at least one of an accommodation facility and an area in which the accommodation facility is located, and includes an acquisition unit that acquires the information, and a control unit that requests a user of the electric vehicle to perform power control including at least one of external charging and external power supply using the electric vehicle at a power stand based on the information acquired by the acquisition unit, and the control unit grants the user a benefit related to the accommodation facility when the user satisfies specified conditions related to the power control.

[0007] In the power management device according to the first aspect of the present disclosure, as described above, when a predetermined condition related to power control is satisfied by a user, a privilege related to an accommodation facility is granted to the user. This encourages users who have obtained the privilege related to the accommodation facility to use the accommodation facility more frequently, thereby promoting use of the accommodation facility. As a result, it is possible to increase the number of users of the accommodation facility. Furthermore, since power control by users who are interested in the privilege is encouraged, the power state of at least one of the accommodation facility and the area in which the accommodation facility is located can be easily adjusted by power control of the electric vehicle.

[0008] In the power management device according to the first aspect, the control unit preferably grants a privilege to the user when the predetermined condition is satisfied at a power stand provided by the user in the accommodation facility. With this configuration, more users will visit the accommodation facility (power stand) to perform power control, and the number of users of the accommodation facility can be further increased.

[0009] In addition, in the power management device according to the first aspect, the control unit preferably grants a privilege to the user at least in one of the following cases: when power is supplied to the accommodation facility by external power supply, and when power control is performed in response to a power supply and demand adjustment request from the power grid in the region. With this configuration, it is possible to prevent the accommodation facility from suffering a power shortage due to power being supplied to the accommodation facility by external power supply. Furthermore, by performing power control in response to a power supply and demand adjustment request from the power grid in the region, it is possible to easily shift (peak shift) and reduce (peak cut) the peak of power usage in the accommodation facility provided in the region. As a result, the accommodation facility can earn profits, and by returning the profits to the user, it is possible to easily grant a privilege to the user.

[0010] In the power management device according to the first aspect, the control unit preferably adjusts the privilege according to the user's contribution to the power control. With this configuration, a user who aims to obtain more privileges will more proactively perform power control, thereby further promoting power control.

[0011] In the power management device according to the first aspect, the provision of the benefit preferably includes at least one of reducing the accommodation facility usage fee, providing at least one of a coupon and points that can be used at the accommodation facility and / or a store in the vicinity of the accommodation facility, and providing a specified service at the accommodation facility at a price lower than the normal price corresponding to the specified service. With this configuration, the user can easily feel a clear advantage in using the accommodation facility. This can further promote the use of the accommodation facility.

[0012] In the power management device according to the first aspect, the predetermined condition preferably includes that the electric vehicle is electrically connected to the power station. With this configuration, it is possible to prevent a user from obtaining a special benefit without performing power control. As a result, it is possible to prevent a malicious user from obtaining a special benefit.

[0013] A power management system according to a second aspect of the present disclosure is a power management device that acquires information regarding the power status of at least one of an accommodation facility and an area in which the accommodation facility is located, and includes an acquisition unit that acquires the information, and a control unit that requests a user of the electric vehicle to perform power control including at least one of external charging and external power supply using the electric vehicle at a power stand based on the information acquired by the acquisition unit, and the control unit grants the user a benefit related to the accommodation facility when the user satisfies specified conditions related to the power control.

[0014] In the power management system according to the second aspect of the present disclosure, as described above, when a predetermined condition related to power control is satisfied by a user, a privilege related to accommodation is given to the user. This promotes the use of accommodation by a user who has obtained the privilege related to accommodation using the accommodation more frequently. As a result, it is possible to provide a power management system that can increase the number of users of accommodation. Effect of the Invention

[0015] According to the present disclosure, it is possible to increase the number of users of accommodation facilities by promoting the use of accommodation facilities. [Brief description of the drawings]

[0017] [First embodiment] Hereinafter, a first embodiment of the present disclosure will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are designated by the same reference characters and their description will not be repeated.

[0018] (Configuration of power management system) Fig. 1 is a diagram showing the configuration of a power management system 1 according to a first embodiment. The power management system 1 includes a server 100, a server 200, an electric vehicle 10, and an EVSE (Electric Vehicle Supply Equipment) 20. Note that the server 100 and the EVSE 20 are examples of the "power management device" and the "power stand" of the present disclosure, respectively.

[0019] The server 100 includes a processor 101, a storage device 102, and a communication unit 103. The processor 101 and the communication unit 103 are examples of a "control unit" and an "acquisition unit," respectively, of the present disclosure.

[0020] The storage device 102 stores the programs executed by the processor 101 as well as information used by the programs (e.g., maps, formulas, and various parameters). The communication unit 103 includes various communication I / Fs. The processor 101 controls the communication unit 103. Specifically, the processor 101 communicates with the server 200 through the communication unit 103. The processor 101 also communicates with a mobile terminal 15 (e.g., a smartphone or a tablet) that can be carried by a user through the communication unit 103.

[0021] Server 100 is also configured to manage information on a plurality of registered electric vehicles 10 (hereinafter also referred to as "vehicle information"), information on each registered user (hereinafter also referred to as "user information"), and information on registered EVSEs 20 (hereinafter also referred to as "EVSE information"). The user information, vehicle information, and EVSE information are stored in storage device 102, distinguished by identification information (ID).

[0022] The user ID is identification information for identifying a user, and also functions as information (terminal ID) for identifying the portable terminal 15 carried by the user. The server 100 is configured to store the information received from the portable terminal 15 separately for each user ID. The user information includes the communication address of the portable terminal 15 carried by the user, and the vehicle ID of the electric vehicle 10 belonging to the user.

[0023] The vehicle ID is identification information for identifying the electric vehicle 10. The vehicle ID may be a license plate or a vehicle identification number (VIN). The vehicle information includes a travel schedule of each electric vehicle 10.

[0024] The EVSE-ID is identification information for identifying the EVSE 20. The EVSE information includes the communication address of each EVSE 20 and the state of the electric vehicle 10 connected to each EVSE 20. The EVSE information also includes information indicating the combination of the electric vehicle 10 and the EVSE 20 that are connected to each other (for example, a combination of the EVSE-ID and a vehicle ID).

[0025] The server 200 is a server that manages the power status of the accommodation facility 300. The accommodation facility 300 includes a hotel, a hot spring inn, and the like. The accommodation facility 300 is equipped with a solar power generation facility 301 that can generate electricity using sunlight. In addition, the energy facilities of the entire building of the accommodation facility 300 are comprehensively monitored and automatically controlled by a BEMS (Building Energy Management System).

[0026] Additionally, the accommodation facility 300 is equipped with an EVSE 20. The EVSE 20 is provided, for example, in a parking lot of the accommodation facility 300. The number of EVSEs 20 may be one or more.

[0027] The EVSE 20 refers to a power supply facility for vehicles. The electric vehicle 10 is configured to be electrically connectable to the EVSE 20. For example, a charging cable 21 connected to the EVSE 20 is connected to an inlet (not shown) of the electric vehicle 10, thereby enabling electric power to be exchanged between the EVSE 20 and the electric vehicle 10.

[0028] Electric vehicle 10 is capable of receiving and sending electric power to and from accommodation facility 300 via EVSE 20. Electric vehicle 10 is configured to be capable of control including external power supply and external charging (hereinafter referred to as power control). Note that electric vehicle 10 may be configured to be capable of only one of external power supply and external charging.

[0029] Furthermore, the electric vehicle 10 may include a DCM (Data Communication Module), and may include a communication I / F compatible with 5G (fifth generation mobile communication system).

[0030] The server 100 acquires information related to the power status of the accommodation facility 300. Specifically, the server 100 (communication unit 103) acquires the above information from the server 200 through communication.

[0031] The server 100 (processor 101) requests the user of the electric vehicle 10 to perform power control in the EVSE 20, based on the information on the power state of the accommodation facility 300 acquired by the communication unit 103. Specifically, the processor 101 requests the user to perform power control in the EVSE 20 of the accommodation facility 300.

[0032] For example, when the accommodation facility 300 is short of power, the processor 101 requests the user to supply power to the accommodation facility 300 by performing external power supply. Note that the power state of the accommodation facility 300 includes not only the current power state of the accommodation facility 300 but also the predicted power state of the accommodation facility 300 taking into consideration, for example, the predicted amount of power generation by the solar power generation facility 301.

[0033] In this case, the processor 101 transmits the request to the user's mobile terminal 15 via the communication unit 103. The request may be transmitted to the electric vehicle 10.

[0034] Here, in the power management system 1 configured as above, it is desired to increase the number of users of the accommodation facility 300 by promoting use of the accommodation facility 300.

[0035] Therefore, the processor 101 gives the user a privilege related to the accommodation facility 300 when a predetermined condition related to power control is satisfied by the user.

[0036] The users to whom the request is sent may include, for example, users who have used the accommodation facility 300 in the past. The users to whom the request is sent may also include users who are located (resident) within a predetermined distance from the accommodation facility 300. The processor 101 may also display the request on a screen of an app or the like while a user is making a reservation for use of the accommodation facility 300 using an app or the like. The users to whom the request is sent may also include users who are staying at the accommodation facility 300 and users who have completed a reservation for use of the accommodation facility 300. The processor 101 may also send the request to all users managed by the server 100.

[0037] Furthermore, the processor 101 may select a user (electrically-driven vehicle 10) to which the request is to be sent based on the SOC (State Of Charge) of the electric vehicle 10. For example, when the accommodation facility 300 is short of power, the processor 101 may send the request to a user of an electric vehicle 10 with a high SOC. When the accommodation facility 300 has surplus power, the processor 101 may send the request to a user of an electric vehicle 10 with a low SOC.

[0038] The above-mentioned predetermined condition also includes that the electric vehicle 10 is electrically connected to the EVSE 20. Specifically, the processor 101 grants a privilege to the user who has responded to the above-mentioned request by accepting the request, based on the electric vehicle 10 of the user being electrically connected to the EVSE 20 of the accommodation facility 300. That is, the user cannot receive the privilege unless the user responds to the above-mentioned request but electrically connects the electric vehicle 10 to the EVSE 20. Also, the user cannot receive the privilege even if the user does not respond to the above-mentioned request and electrically connects the electric vehicle 10 to the EVSE 20.

[0039] The privilege may be given to the user on the condition that power control has been performed for a predetermined time or more (for example, 15 minutes or more) (or the user has set the power control to be performed for a predetermined time or more). In addition, when the electric vehicle 10 is electrically connected to the EVSE 20, the privilege may be given to the user even if the user does not comply with the request.

[0040] Furthermore, if the user complies with the request, the privilege may be granted to the user before the electric vehicle 10 is electrically connected to the EVSE 20. In this case, the granted privilege may be enabled based on the fact that the electric vehicle 10 is electrically connected to the EVSE 20.

[0041] A predetermined penalty may be imposed on a user who has been given a privilege but has not performed power control, at the next power control in EVSE 20 of accommodation facility 300 or an EVSE in another facility. Specifically, control may be performed so that a predetermined reward (such as the privilege or monetary reward) is not given to the user even if the user performs power control.

[0042] In the first embodiment, the processor 101 adjusts the privilege according to the degree of contribution of the user in power control. In other words, the processor 101 adjusts the privilege according to the degree of contribution of the user to the request for power control to the user. For example, when the user is requested to supply external power due to a power shortage in the accommodation facility 300, the processor 101 adjusts the privilege according to the amount of power supply by the power control (degree of contribution to resolving the power shortage). In this case, the privilege may be adjusted based on not only the amount of power supply but also other factors (for example, the power supply start time and the power supply duration, etc.).

[0043] The above-mentioned reward may be adjusted based on factors other than the degree of contribution to power control. For example, the reward may be adjusted based on the current or past amount of power usage in the accommodation facility 300 (lodging room, room used) of the user.

[0044] Moreover, granting the above-mentioned benefit includes, for example, a reduction in the usage fee of the accommodation facility 300. The usage fee of the accommodation facility 300 includes the accommodation fee, the usage fee of the restaurants and facilities (gym, recreation room, etc.) within the accommodation facility 300, etc. The usage fee may also include the fee required for early check-in to the accommodation facility 300 and the fee required for late check-out from the accommodation facility 300.

[0045] Moreover, the provision of the above-mentioned benefits includes the provision of complimentary tickets (coupons) and points that can be used at the accommodation facilities 300 and the stores 30. The complimentary tickets and points are provided through an app that can be used on the mobile terminal 15 or the like. The complimentary tickets may be provided directly to the user (by handing them over without communication).

[0046] 1 is, for example, a store near an accommodation facility 300. The store 30 includes, for example, a store where bicycles can be rented. A user (a user of the accommodation facility 300) who satisfies the above-mentioned predetermined conditions in power control is given a coupon or points that enable the user to rent a bicycle at the store 30 at a lower price than usual.

[0047] Additionally, an additional (or more valuable) benefit may be given to users who exercise power control during the day.

[0048] In addition, since it is expected that sales at the store 30 will increase by providing the user with complimentary coupons or points that can be used at the store 30, a predetermined amount of commission (margin) may be paid to the accommodation facility 300 from the store 30.

[0049] Moreover, the provision of the above-mentioned benefit includes providing a predetermined service at the accommodation facility 300 at a price lower than the normal price corresponding to the predetermined service. For example, the predetermined service includes a service of providing beverages (such as tea and alcohol) free of charge.

[0050] In the above, an example has been described in which power is supplied from the electric vehicle 10 to the accommodation facility 300, but the present disclosure is not limited to this. When the accommodation facility 300 has surplus power, the user may be requested to use the power of the accommodation facility 300 to charge the electric vehicle 10 by performing external charging. In this case, the privilege may be adjusted based on the amount of charge by external charging of the electric vehicle 10, the charging start time, the charging time, etc. (degree of contribution to eliminating surplus power).

[0051] When external charging is required as described above, a privilege corresponding to the electric vehicle 10 being connected to the EVSE 20 in a time period (e.g., 12:00) earlier than the normal check-in time may be given to the user. In this case, a privilege is given for the electric vehicle 10 performing external charging (contribution to eliminating surplus power) in a time period when the amount of power generated by the solar power generation facility 301 is relatively large.

[0052] Furthermore, when external charging is required, a privilege may be given to the user of electric vehicle 10 to use the accommodation room for work or the like during a time period earlier than the normal check-in time (for example, 11:00 to 15:00).

[0053] In these cases, the rewards may include, for example, tickets to the gym and bath at the accommodation facility 300.

[0054] The user may be able to select at least one of the various benefits described above. A detailed description of this control will be given later.

[0055] (Power management method) Next, an example of sequence control by the power management system 1 until a privilege is given to a user will be described with reference to a sequence diagram of FIG.

[0056] First, in step S1, the server 100 (communication unit 103) receives information about the power status of the accommodation facility 300 from the server 200.

[0057] Next, in step S2, the processor 101 determines a user (electrically-powered vehicle 10) for which power control is to be requested. Specific examples of the selection criteria are as described above. Note that, when the request is to be sent to all users managed by the server 100, step S2 does not need to be provided.

[0058] Next, in step S3, based on the information received in step S1, the processor 101 requests the user selected in step S2 to perform power control (e.g., external power feeding) in the EVSE 20 of the accommodation facility 300. Note that the server 100 may transmit an inquiry signal for requesting power control directly to the electric vehicle 10, or may transmit it to the mobile terminal 15 of the user.

[0059] Next, in step S4, it is assumed that the user transmits to server 100 a signal indicating acceptance (participation in power control) of the power control request in step S3.

[0060] Next, in step S5, it is assumed that the electrically powered vehicle 10 is electrically connected to the EVSE 20, and power control corresponding to the request for power control in step S3 is started.

[0061] Next, in step S6, processor 101 calculates the degree of contribution of the user in the power control. For example, processor 101 calculates the degree of contribution based on the details (charging / power supply time, charging / power supply amount, charging / power supply start time) agreed between electric vehicle 10 and server 100 in steps S3 and S4. Also, the degree of contribution may be calculated based on an integrated value of power control by the user (the number of power controls up to now, and the integrated value of the charging (power supply) amount up to now, etc.). The calculation of the degree of contribution in step S6 may be performed between steps S4 and S5. The calculation of the degree of contribution in step S6 may be performed based on the actual charging (power supply) amount after the power control is completed. In this case, the information on the charging (power supply) amount is transmitted from server 200 to server 100.

[0062] Next, in step S7, the processor 101 confirms with the user whether or not to select a benefit to be used. For example, the server 100 (processor 101) controls the communication unit 103 so that a message screen 15a (see FIG. 3) for confirming whether or not to select a benefit is displayed on the user's mobile terminal 15. The message screen 15a displays a button 15b marked "YES" and a button 15c marked "NO". When the button 15b marked "YES" is selected, information indicating that a benefit is requested to be selected is transmitted to the server 100. When the button 15c marked "NO" is selected, information indicating that a benefit is not requested to be selected is transmitted to the server 100. The process of step S7 may be performed before the process of step S6.

[0063] Next, in step S8, it is assumed that the user has responded to the confirmation in step S7 by selecting either button 15b labeled "YES" or button 15c labeled "NO" on message screen 15a.

[0064] Next, in step S9, processor 101 determines whether or not the user has requested to select a privilege. If the user has requested to select a privilege in step S8 (i.e., button 15b marked "YES" is selected), processor 101 determines that the user has requested to select the privilege, and the process proceeds to step S91 (Yes in S9). If the user has not requested to select a privilege in step S8 (i.e., button 15c marked "NO" is selected), processor 101 determines that the user has not requested to select the privilege, and the process proceeds to step S93 (No in S9).

[0065] In step S91, the processor 101 controls the communication unit 103 so that data of the benefit selection screen 15d (see FIG. 4) is transmitted to the user's mobile terminal 15. As a result, the selection screen 15d is displayed on the mobile terminal 15. At this time, the types (number) of benefits selectable on the selection screen 15d, the available period, etc. are adjusted (restricted) based on the degree of contribution calculated in step S6.

[0066] Next, in step S92, the user selects at least one of the multiple benefits displayed on the selection screen 15d. For example, when at least one of the benefits displayed on the selection screen 15d is selected and a button 15e (see FIG. 4) labeled “Complete” is selected on the selection screen 15d, information on the benefit selected by the user is transmitted to the server 100.

[0067] On the other hand, in step S93, the processor 101 randomly selects at least one of a plurality of benefits prepared in advance. At this time, the processor 101 adjusts the type (number) of benefits to be selected and the available period, etc., based on the degree of contribution. The processor 101 may select a benefit by referring to the user's past benefit usage history, etc.

[0068] Then, in step S10, the processor 101 transmits, via the communication unit 103, the benefit (the complimentary coupon, the points, etc.) selected in step S92 or step S93 to the mobile terminal 15 of the user.

[0069] The above-described power management method by the power management system 1 is merely an example, and the present disclosure is not limited to the above example. For example, the selection of a privilege or the adjustment of a privilege based on the degree of contribution may not be performed.

[0070] As described above, in the first embodiment, the processor 101 grants a privilege to a user when the above-mentioned predetermined condition related to power control is satisfied by the user and when the user uses the accommodation facility 300 (when using the accommodation facility). This makes it possible to increase the number of users of the electric vehicle 10 who use the accommodation facility 300 in order to receive the privilege. In addition, it is possible to easily prevent the power condition of the accommodation facility 300 from deteriorating due to the use of power from the electric vehicle 10.

[0071] [Second embodiment] Next, a server 110 and a power management system 2 according to a second embodiment will be described with reference to FIGS.

[0072] (Configuration of power management system) Fig. 5 is a diagram showing the configuration of a power management system 2 according to a second embodiment. The power management system 2 includes a server 110, a server 210, a power system management server 400, an electric vehicle 10, an EVSE 20, and a power system PG. The power management system 2 is a system that manages the power supply and demand state of the power system PG for each power adjustment resource (such as accommodation facilities 300, electric vehicle 10, building 510, and building 520) in an area 500. In the example shown in Fig. 5, a plurality of EVSEs 20 are provided in the area 500, which will be described later. The server 110 is an example of a "power management device" in the present disclosure.

[0073] The server 110 includes a processor 111, a storage device 112, and a communication unit 113. The processor 111 and the communication unit 113 are examples of a "control unit" and an "acquisition unit," respectively, of the present disclosure.

[0074] The server 210 is a server that manages the power state of the accommodation facility 300. Each of the multiple EVSEs 20 is electrically connected to the power grid PG. Therefore, the multiple EVSEs 20 are electrically connected to each other via the power network of the power grid PG. Note that, although the power grid PG is not shown in FIG. 1 of the first embodiment, the power grid PG and the EVSEs 20 are electrically connected to each other in the same manner as in the second embodiment.

[0075] The power system PG is a power grid constructed by a power plant and a power transmission and distribution facility (not shown). In the second embodiment, an electric power company serves as both a power generation business operator and a power transmission and distribution business operator. The electric power company corresponds to a general power transmission and distribution business operator, and maintains and manages the power system PG. The electric power company corresponds to a manager of the power system PG.

[0076] The grid management server 400 manages the supply and demand of the power grid PG (power network). The grid management server 400 belongs to a power company. The grid management server 400 transmits a request (supply and demand adjustment request) to adjust the power demand of the power grid PG based on the power generation and consumption by each power adjustment resource in the area 500 to the server 110 (communication unit 113). Specifically, when the power generation or power consumption of the power adjustment resource is expected to be higher than usual (or is currently higher), the grid management server 400 transmits a request to the server 110 to increase or decrease the power demand compared to normal. The above supply and demand adjustment request is an example of the "information on the power state of the area" and the "power supply and demand adjustment request from the power grid" of the present disclosure.

[0077] The processor 111 requests the user of the electric vehicle 10 to perform power control in the EVSE 20 based on the supply and demand adjustment request acquired by the communication unit 113. For example, when the processor 111 receives a request to increase the power demand amount compared to normal times, the processor 111 requests the user to perform external charging in the EVSE 20. In addition, when the processor 111 receives a request to decrease the power demand amount compared to normal times, the processor 111 requests the user to perform external power feeding in the EVSE 20.

[0078] Here, in the second embodiment, when power control is performed in response to the supply and demand adjustment request (when a predetermined condition related to power control is satisfied), the processor 111 grants the user a privilege related to the accommodation facility 300. Note that in the second embodiment, the privilege is granted to the user not only when power control is performed using the EVSE 20 in the accommodation facility 300, but also when power control is performed using any EVSE 20 in the area 500.

[0079] 5, since only the accommodation facility 300 exists in the area 500, a benefit related to the accommodation facility 300 (usable at the accommodation facility 300 and the store 30) is given to the user. On the other hand, if there are multiple accommodation facilities in the area 500, the user may be given a benefit that can be used at any of the multiple accommodation facilities (and the stores near each accommodation facility).

[0080] In the second embodiment, the processor 111 adjusts the privilege to be given to the user based on the degree of contribution to a supply and demand adjustment request from the power system PG (system management server 400).

[0081] The peak of the electricity usage of the accommodation facility 300 can be easily shifted (peak shift) and lowered (peak cut) by the user's power control. Based on this performance, the contract fee between the accommodation facility 300 and the power company is reduced, and the amount that can be spent on special benefits is increased.

[0082] (Electric management method) Next, an example of a power management method by the server 110 will be described with reference to the sequence diagram of Fig. 6. Note that the same contents as those in the first embodiment will not be described repeatedly.

[0083] First, in step S11 , the communication unit 113 receives a supply and demand adjustment request from the grid management server 400 .

[0084] In step S13, based on the information received in step S11, the processor 111 requests the user selected in step S2 to perform power control on the EVSE 20 in the area 500. Note that the processor 111 may request to perform power control on a specific EVSE 20 (for example, the EVSE 20 in the accommodation facility 300).

[0085] As described above, in the second embodiment, the processor 111 grants a privilege to a user when a predetermined condition related to power control is satisfied by the user and the user uses the accommodation facility 300. This makes it possible to increase the number of users of the electric vehicle 10 who use the accommodation facility 300 in order to receive the privilege, as in the first embodiment. Furthermore, by promoting power control by the electric vehicle 10, it is possible to improve the power supply and demand balance of the power system PG by each power adjustment resource in the area 500.

[0086] The other configurations and effects are the same as those of the first embodiment, and therefore detailed description will not be repeated.

[0087] In addition, in the above first embodiment, an example has been described in which a privilege is granted when power control is performed in the EVSE 20 of the accommodation facility 300, but the present disclosure is not limited to this. Power control may be performed in any EVSE as long as the EVSE is present in a common power grid with the EVSE 20 of the accommodation facility 300.

[0088] In the above first and second embodiments, a privilege is given to a user who satisfies a predetermined condition regarding power control, but the present disclosure is not limited to this. For example, a privilege may be given to a user when a predetermined condition regarding power control is satisfied and the user uses (or plans to use) the accommodation facility 300.

[0089] The embodiments disclosed herein should be considered to be illustrative and not restrictive in all respects. The scope of the present disclosure is defined by the claims, not by the description of the embodiments described above, and is intended to include all modifications within the meaning and scope of the claims.
