Description

[Technical Field]

[0001] The present invention relates to a charging and supplying management system, and more particularly to a charging and supplying management system that manages charging and supplying of power to a power storage device mounted on a mobile object. [Background technology]

[0002] In recent years, research and development has been conducted into charging mobile vehicles equipped with secondary batteries that contribute to energy efficiency, in order to ensure that more people have access to affordable, reliable, sustainable, and advanced energy.

[0003] Many electric vehicles that run using power stored in an on-board secondary battery (hereinafter also referred to as "on-board battery") have both a charging function that charges the on-board battery with power supplied from an external power source and a power supply function that supplies the power stored in the on-board battery to an external load. In recent years, users of electric vehicles have been able to charge and supply power not only at their own homes but also at various facilities where the electric vehicle travels (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Publication No. 2020-162395 Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, at a power generation facility that has a power generation surplus for some reason (i.e., a facility equipped with a power generation facility and a charging facility that charges an onboard battery with the power generated by the power generation facility), a user may be able to charge the power more cheaply than charging the onboard battery at home. Also, at a power supply facility that has a power shortage for some reason (i.e., a facility equipped with an electric load and a power supply facility that supplies the power of the onboard battery to the electric load), a user may be able to sell the power more expensively than if the onboard battery were to supply power to the home.

[0006] In this way, when there are various charging facilities and power supply facilities outside of the home, it is thought that the benefits that users can obtain will vary depending on the location of charging. However, until now, there has been insufficient research into the location where users should charge their vehicles to obtain the most benefits.

[0007] The present invention aims to provide a charging and power supply management system that manages the charging and power supply of a power storage device so as to bring benefits to users of mobile bodies having the power storage device, and thereby contributes to improving energy efficiency. [Means for solving the problem]

[0009] (2) In this case, when the current location is the same as the location of a target station defined for each target mobile body, the user benefit calculation means calculates the benefit that the target user will gain when power is supplied from the storage device to the target station as the station power supply benefit, and when the differential benefit obtained by subtracting the mobile power supply cost from the mobile power supply benefit is greater than the station power supply benefit, it is preferable that the plan transmission means transmits the mobile power supply plan to the target terminal or the target mobile body.

[0010] (3) In this case, if the target moving body is an electric vehicle that runs using the power of the storage device, it is preferable that the travel cost calculation means calculates the mobile power supply cost based on the electricity cost of the target moving body and the electricity rate unit price of the target station.

[0011] (4) In this case, the charging and power supply management system preferably further includes a usage schedule determination means (e.g., the usage schedule determination unit 13 described below) for determining whether or not there is a usage schedule for the target mobile body between now and a predetermined time in the future, and the plan transmission means preferably transmits the mobile power supply plan to the target terminal or the target mobile body when it is determined that there is a power supply margin in the storage device, that there is no usage schedule for the target mobile body, and the differential profit is greater than the station power supply profit.

[0012] (5) In this case, if the target moving body is an unmanned autonomous vehicle, it is preferable that the plan transmission means transmits to the target moving body the mobile power supply plan including information necessary to automatically move the target moving body from its current location to the power supply request facility.

[0013] (6) In this case, it is preferable that the user profit calculation means sequentially calculates the mobile power supply profit based on the latest power supply request facility information, and the plan transmission means transmits a cancellation notice for the notified mobile power supply plan if the differential profit becomes less than the station power supply profit while the target mobile body is moving toward the power supply request facility.

[0014] (7) A charging and power supply management system (for example, charging and power supply management system 1 described later) according to the present invention manages charging and power supply to a power storage device (for example, on-board batteries B1, B2, ... described later) mounted on a target moving body (for example, moving bodies M1, M2, ... described later), and includes a target information acquisition means (for example, target information acquisition unit 12 described later) that acquires target information including information on the current location of the target moving body and the state of the power storage device, a facility information acquisition means (for example, facility information acquisition unit 15 described later) that extracts a facility for which charging is requested from a plurality of facilities (for example, facilities F1, F2, F3, ... described later) present in a target area including the current location as a charging request facility and acquires charging request facility information related to the charging request facility, and a margin determination unit that determines whether there is a margin for charging by the power storage device based on the target information. The system is characterized by comprising: a determination means (e.g., a slack determination unit 14 described later) that calculates the cost to be borne by the target user of the target mobile body due to movement between the current location and the charging request facility by the target mobile body as a mobile charging cost; a user benefit calculation means (e.g., a user benefit calculation unit 17 described later) that calculates the benefit that the target user will obtain when charging the storage device from the charging request facility as a mobile charging profit; and a plan transmission means (e.g., a plan transmission unit 18 described later) that transmits a mobile charging plan generated based on the target information and the charging request facility information to the target terminal of the target user or the target mobile body when it is determined that there is charging slack in the storage device and the mobile charging profit is greater than the mobile charging cost.

[0015] (8) In this case, it is preferable that the user benefit calculation means calculates the mobile charging benefit by subtracting the cost that the target user will incur when charging the storage device from the charging request facility from the cost that the target user will incur when charging the storage device from the target station specified for each target mobile body.

[0016] (9) In this case, if the target mobile body is an electric vehicle that runs using the power of the storage device, it is preferable that the travel cost calculation means calculates the mobile charging cost based on the electricity cost of the target mobile body and the electricity rate unit price of the target station.

[0017] (10) In this case, the charging and power management system preferably further includes a usage schedule determination means (e.g., the usage schedule determination unit 13 described below) for determining whether or not there is a usage schedule for the target mobile body between now and a predetermined time in the future, and the plan transmission means preferably transmits the mobile charging plan to the target terminal or the target mobile body when it is determined that there is charging capacity in the storage device, that there is no usage schedule for the target mobile body, and that the mobile charging benefit is greater than the mobile charging cost.

[0018] (11) In this case, if the target mobile body is an unmanned autonomous vehicle, it is preferable that the plan transmission means transmits to the target mobile body the mobile charging plan including information necessary to automatically move the target mobile body from its current location to the charging request facility.

[0019] (12) In this case, it is preferable that the user benefit calculation means sequentially calculates the mobile charging benefit based on the latest charging request facility information, and that the plan transmission means transmits a cancellation notification for the notified mobile charging plan if the mobile charging benefit becomes less than the mobile charging cost while the target mobile body is moving toward the charging request facility. [Effects of the Invention]

[0020] (1) In the present invention, the target information acquisition means acquires target information regarding the current location of the target mobile object and the status of the power storage device, the facility information acquisition means extracts a power supply request facility from multiple facilities around the current target mobile object (i.e., within the target area) and acquires power supply request facility information regarding the power supply request facility, the margin determination means determines whether or not there is a power supply margin from the power storage device, the travel cost calculation means calculates the cost borne by the target user for travel between the current location of the target mobile object and the power supply request facility as a mobile power supply margin, and the user benefit calculation means calculates the benefit that the target user will gain if the power storage device supplies power to the power supply request facility as a mobile power supply margin. Furthermore, if it is determined that there is a power supply margin in the power storage device and the mobile power supply margin is greater than the mobile power supply cost, i.e., if it is determined that the target user will benefit by moving the target mobile object from its current location to the power supply request facility and supplying power at this destination, the plan transmission means transmits a mobile power supply plan generated based on the target information and the power supply request facility information to the target terminal of the target user or the target mobile object. This allows the target user to recognize that they can benefit by moving the target mobile object to the power supply request facility and supplying power at this destination, which encourages the target mobile object to move to the power supply request facility and supply power at the destination, thereby bringing benefits to the target user. Furthermore, by encouraging power supply at facilities where power demand is high in this way, unnecessary demand response can be avoided, which can contribute to improving energy efficiency.

[0021] (2) In the present invention, when the current location is the same as the location of a target station defined for each target mobile object, the user benefit calculation means calculates the benefit that the target user will gain when power is supplied from the power storage device to the target station as the station power supply benefit, and the plan transmission means transmits a mobile power supply plan to the target terminal or target mobile object when the difference benefit obtained by subtracting the mobile power supply cost from the mobile power supply benefit is greater than the station power supply benefit, i.e., when a greater benefit can be gained by moving the target mobile object to the power supply request facility and supplying power at this destination than by supplying power to the target station without moving the target mobile object from the target station. This makes it possible to more reliably bring benefits to the target user.

[0022] (3) Users of electric vehicles often charge their power storage devices at specific target stations. Therefore, if the target moving object is an electric vehicle that runs using power from a power storage device, the travel cost calculation means calculates the mobile power supply cost based on the electricity cost of the target moving object and the electricity unit price of the target station. This can improve the accuracy of the profit that the user will obtain when power is supplied based on the mobile power supply plan.

[0023] (4) In the present invention, the use schedule determination means determines whether or not there is a use schedule for the target mobile object from the present time until a predetermined time in the future, and the plan transmission means transmits a mobile power supply plan to the target terminal or the target mobile object when it is determined that there is a power supply surplus in the power storage device, that there is no use schedule for the target mobile object, and the differential profit is greater than the station power supply profit. As a result, even if the target mobile object is intended to be used by unspecified persons other than the target user, it is possible to bring benefits to the target user by utilizing the time when the target mobile object is not in use.

[0024] (5) In the present invention, when the target moving body is an unmanned autonomous vehicle, the plan transmission means transmits to the target moving body a mobile power supply plan including information necessary for automatically moving the target moving body from its current location to the power supply request facility, thereby causing the target moving body to automatically move to the power supply request facility and receive power at the destination.

[0025] (6) The demand for power at the power supply request facility changes continuously. Therefore, the user benefit calculation means successively calculates the mobile power supply benefit based on the latest power supply request facility information. If the differential benefit becomes less than the station power supply benefit while the target mobile object is moving toward the power supply request facility, the plan transmission means transmits a cancellation notice for the notified mobile power supply plan to the target terminal or the target mobile object. This makes it possible to minimize the disadvantages incurred by the target user.

[0026] (7) In the present invention, the target information acquisition means acquires target information related to the current location of the target mobile object and the status of the power storage device, the facility information acquisition means extracts a charging request facility from multiple facilities around the current target mobile object (i.e., within the target area) and acquires charging request facility information related to the charging request facility, the margin determination means determines whether there is a charging margin for the power storage device, the travel cost calculation means calculates the cost borne by the target user for travel between the current location of the target mobile object and the charging request facility as the mobile charging cost, and the user benefit calculation means calculates the benefit that the target user will obtain if the target user charges the power storage device from the charging request facility as the mobile charging benefit. Furthermore, if it is determined that there is a charging margin for the power storage device and the mobile charging benefit is greater than the mobile charging cost, i.e., if it is determined that the target user will obtain a benefit by moving the target mobile object from its current location to the charging request facility and charging at this destination, the plan transmission means transmits a mobile charging plan generated based on the target information and the charging request facility information to the target terminal of the target user or the target mobile object. This allows the target user to recognize that they can benefit by moving the target mobile body to the charging request facility and charging at the destination, which encourages the target mobile body to move to the charging request facility and charge at the destination, thereby bringing benefits to the target user. Furthermore, by encouraging charging at facilities where charging demand is high in this way, unnecessary demand response can be avoided, which can contribute to improving energy efficiency.

[0027] (8) In the present invention, the user benefit calculation means calculates the mobile charging benefit by subtracting the cost that the target user will incur when charging the power storage device from the charging request facility from the cost that the target user will incur when charging the power storage device from the target station. This makes it possible to more reliably provide benefits to the target user.

[0028] (9) In the present invention, when the target mobile object is an electric vehicle that runs using power from a power storage device, the travel cost calculation means calculates the mobile charging cost based on the electricity cost of the target mobile object and the electricity unit price of the target station. This can improve the accuracy of the profit that the user can obtain when charging based on the mobile charging plan.

[0029] (10) In the present invention, the use schedule determination means determines whether or not there is a plan for using the target mobile object from the present time until a predetermined time in the future, and the plan transmission means transmits a mobile charging plan to the target terminal or the target mobile object when it is determined that there is a charge margin in the power storage device, that there is no plan for using the target mobile object, and that the mobile charging benefit is greater than the mobile charging cost. This allows the target user to benefit from the time when the target mobile object is not in use, even if the target mobile object is intended to be used by unspecified persons other than the target user.

[0030] (11) In the present invention, when the target mobile object is an unmanned autonomous vehicle, the plan transmission means transmits to the target mobile object a mobile charging plan including information necessary for automatically moving the target mobile object from its current location to a charging request facility. This allows the target mobile object to automatically move to the charging request facility and be charged at the destination.

[0031] (12) The demand for electricity at a charging request facility changes continuously. Therefore, the user benefit calculation means successively calculates the mobile charging benefit based on the latest charging request facility information. If the mobile charging benefit becomes less than the mobile charging cost while the target mobile body is moving toward the charging request facility, the plan transmission means transmits a cancellation notice for the notified mobile charging plan to the target terminal or the target mobile body. This makes it possible to minimize the disadvantages incurred by the target user. [Brief explanation of the drawings]

[0032] [Figure 1] 1 is a diagram schematically illustrating a configuration of a charging and supply management system according to an embodiment of the present invention and a portion of a management area of ​​the charging and supply management system. [Figure 2] FIG. 2 is a functional block diagram showing the configuration of a charging and power management system. DETAILED DESCRIPTION OF THE INVENTION

[0033] Hereinafter, a charging and supply management system according to an embodiment of the present invention will be described with reference to the drawings.

[0034] 1 is a diagram schematically illustrating the configuration of a charging and supplying management system 1 according to this embodiment and a portion of a management area A of this charging and supplying management system 1. Within the management area A, there are a plurality of mobile objects M1, M2, M3, M4, M5, ... and a plurality of facilities F1, F2, F3, ... and charging stations S1, S2, ... that can charge or supply power to secondary batteries B1, B2, B3, B4, B5, ... (hereinafter, secondary batteries mounted on mobile objects are also referred to as "on-board batteries") mounted on these mobile objects M1, M2, ... as power storage devices.

[0035] The first facility F1 is a power supply facility equipped with an electrical load, a plurality of secondary batteries (hereinafter, the secondary batteries installed in the facility will also be referred to as "facility batteries" to distinguish them from vehicle batteries B1, B2, etc.), and power supply equipment that supplies the power supplied from these facility batteries and vehicle batteries to the above-mentioned electrical loads.

[0036] That is, a user of a third mobile object M3 located at the first facility F1 can supply power stored in the on-board battery B3 to the electrical loads of the first facility F1 by connecting the on-board battery B3 to the power supply equipment. By supplying power from the on-board battery B3 to the first facility F1 in this manner, the user of the third mobile object M3 can obtain a profit proportional to the product of the amount of power supplied from the on-board battery B3 to the first facility F1 (hereinafter also referred to as the "amount of supplied power") and the power purchase price set by the first facility F1. Note that, hereinafter, the act of a mobile object user exchanging their on-board battery for a facility battery with a lower remaining charge is also referred to as "power supply." The power purchase price at the first facility F1 changes as appropriate depending on the power demand at the first facility F1, the remaining charge of the facility battery, the number of facility batteries, and the like.

[0037] The second facility F2 is a charging facility equipped with a power generation facility that generates electricity using renewable energy such as solar and wind power, multiple facility batteries, and charging equipment that charges these facility batteries and on-board batteries with electricity generated by the power generation facility.

[0038] That is, a user of a fourth mobile object M4 located at the second facility F2 can charge the on-board battery B4 by connecting the on-board battery B4 to a charging facility. When the user of the fourth mobile object M4 charges the on-board battery B4 from the second facility F2 in this manner, the user must pay the second facility F2 a fee proportional to the product of the amount of power supplied from the second facility F2 to the on-board battery B4 (hereinafter also referred to as "the amount of charged power") and the electricity selling price determined at the second facility F2. Note that, hereinafter, the act of a mobile object user exchanging their on-board battery for a facility battery with a higher remaining charge is also referred to as charging. The electricity selling price at the second facility F2 varies as appropriate depending on the demand for power at the second facility F2, the remaining charge of the facility battery, the number of facility batteries, and the like.

[0039] The third facility F3 is a charging and supplying facility equipped with an electrical load, multiple facility batteries, power supply equipment, power generation equipment, and charging equipment. That is, a user of a fifth mobile object M5 located at the third facility F3 can supply power from an on-board battery B5 to the third facility F3 or charge the on-board battery B5 from the third facility F3. Furthermore, similar to the above-mentioned facilities F1 and F2, the user of the mobile object M5 can earn profits by supplying power and must pay a fee for charging.

[0040] The first charging station S1 is the home of the user of the first mobile object M1. The first charging station S1 is a charging facility equipped with an electric load, a power supply facility, and a charging facility. That is, the user of the first mobile object M1 parks the first mobile object M1 in a parking lot at their home, allowing the user to supply power from their on-board battery B1 to the first charging station S1 and charge their on-board battery B1 from the first charging station S1.

[0041] When the user of the first mobile body M1 charges the vehicle battery B1 from the first charging station S1 in this manner, the user must pay to the electric power company a fee proportional to the product of the amount of electricity charged from the first charging station S1 to the vehicle battery B1 and the electricity rate set at the first charging station S1.

[0042] Furthermore, by supplying power from the on-board battery B1 to the first charging station S1 in this manner, the user of the first moving object M1 can obtain a benefit proportional to the amount of power supplied from the on-board battery B1 to the first charging station S1. Here, the benefit obtained by the user of the first moving object M1 by supplying power from the on-board battery B1 to the first charging station S1 corresponds to, for example, the reduction in the cost paid by the user to the electric power company by supplying power from the on-board battery B1 to the first charging station S1. In this way, the user of the first moving object M1 can obtain a benefit by supplying power from the on-board battery B1 to the first charging station S1, but the opportunities to supply power are limited depending on the usage status of the electrical load at the first charging station S1.

[0043] The second charging station S2 is the home of the user of the second mobile object M2. The second charging station S2 is a charging facility equipped with an electric load, a power supply facility, a charging facility, and a power generation facility. In other words, the user of the second mobile object M2 can park the second mobile object M2 in a parking lot at their home to supply power from their on-board battery B2 to the second charging station S2 or charge their on-board battery B2 from the second charging station S2.

[0044] When the user of the second mobile body M2 charges the vehicle battery B2 from the second charging station S2 in this manner, the user must pay the electric power company a fee based on the amount of power charged from the second charging station S2 to the vehicle battery B2, the electricity rate set at the second charging station S2, and the power generation status of the power generation equipment at that time.

[0045] Furthermore, by supplying power from the on-board battery B2 to the second charging station S2 in this manner, the user of the second mobile object M2 can obtain a benefit proportional to the amount of power supplied from the on-board battery B2 to the second charging station S2. Here, the benefit obtained by the user of the second mobile object M2 by supplying power from the on-board battery B2 to the second charging station S2 corresponds to, for example, the reduction in the cost paid by the user to the electric power company by supplying power from the on-board battery B2 to the second charging station S2. In this way, the user of the second mobile object M2 can obtain a benefit by supplying power from the on-board battery B2 to the second charging station S2, but the opportunities to supply power are limited depending on the usage status of the electrical load at the second charging station S2, the power generation status of the power generation equipment, etc.

[0046] In the following, the mobile bodies M1, M2, ... are described as electric vehicles that run using power stored in onboard batteries B1, B2, ... and are private vehicles owned by users of the mobile bodies M1, M2, ..., but the present invention is not limited to this. The mobile bodies may be equipped with an internal combustion engine that generates driving force by consuming hydrocarbon fuel. Furthermore, the mobile bodies are not limited to private vehicles owned by users, but may also be commercial vehicles (e.g., MaaS vehicles, ride-sharing vehicles, etc.) used by users or persons other than users for businesses run by the users. Furthermore, the mobile bodies may be dedicated facility battery transport vehicles that transport and exchange multiple facility batteries between the multiple facilities F1, F2, F3, ....

[0047] The charging and power supply management system 1 extracts one or more of the multiple mobile bodies M1, M2, ... existing within the management area A as target mobile bodies, transmits a plan for charging the onboard battery of the target mobile body to the mobile information terminal owned by the user of the target mobile body (hereinafter also referred to as the "target user") or to the target mobile body, and manages the charging and power supply of the onboard battery of the target mobile body by encouraging charging in accordance with this plan.

[0048] The charging and power management system 1 is configured by one or more computers communicably connected via base stations to facilities F1, F2, F3, ..., charging stations S1, S2, ..., mobile objects M1, M2, ..., and mobile information processing terminals owned by users of the mobile objects M1, M2, ... (hereinafter, these facilities F1, F2, F3, ..., etc. are also collectively referred to as "area terminals") that exist within the management area A. More specifically, the charging and power management system 1 is configured by servers connected to the multiple facilities F1, F2, F3, ..., etc. via base stations, network cores, and the Internet, and edge servers connected to the multiple area terminals via base stations and MEC (Multi-access Edge Computing) cores, etc.

[0049] 2 is a functional block diagram showing the configuration of the charging and power management system 1. The charging and power management system 1 includes a target moving object extraction unit 11, a target information acquisition unit 12, a usage schedule determination unit 13, a surplus determination unit 14, a facility information acquisition unit 15, a travel cost calculation unit 16, a user profit calculation unit 17, and a plan transmission unit 18. The functions of each of the blocks 11 to 18 described below are realized by the charging and power management system 1, which is a computer, executing a program stored in a storage medium (not shown).

[0050] The target moving object extraction unit 11 extracts one or more moving objects M1, M2, . . . that exist within the management area A as target moving objects.

[0051] The target information acquisition unit 12 acquires target information including the current location of the target moving body extracted by the target moving body extraction unit 11, information regarding the status of the onboard battery (hereinafter also referred to as the "target battery") installed in the target moving body, and information regarding the status of the target station of the target moving body (i.e., in the example of Figure 1, the first charging station S1 corresponds to the target station of the first moving body M1, and the second charging station S2 corresponds to the target station of the second moving body M2) from the target moving body, the mobile information terminal owned by the target user, the target station, etc. The target information acquired by the target information acquisition unit 12 includes current location information of the target mobile object, performance information on the performance of the target mobile object (i.e., electricity cost, fuel efficiency, etc.), type information on the type of the target mobile object (i.e., private vehicle, commercial vehicle, or vehicle dedicated to transporting facility batteries), the number of target batteries installed in the target mobile object, the SOC [%] representing the current remaining capacity of each target battery expressed as a percentage, the lower limit of SOC after mobile power supply of each target battery, the upper limit of SOC after mobile charging of each target battery, information on the degree of deterioration of each target battery, the operating rate of the electrical load of the target station, the power generation status of the power generation equipment of the target station, the unit price of electricity of the target station, and the location of the target station, etc. The target information acquisition unit 12 transmits the acquired target information to the slack determination unit 14, travel cost calculation unit 16, user profit calculation unit 17, plan transmission unit 18, etc., which will be described later.

[0052] Here, the term "SOC lower limit after mobile power supply" refers to the lower limit of the SOC of the target battery after power supply at the destination facility based on the mobile power supply plan described below. The term "SOC upper limit after mobile charging" refers to the upper limit of the SOC of the target battery after charging at the destination facility based on the mobile charging plan described below. These SOC lower limit and SOC upper limit after mobile power supply and SOC upper limit are determined in advance by the target user, for example, to prevent deterioration of the target battery.

[0053] The use schedule determination unit 13 acquires schedule information specifying the vehicle to be used for the target mobile object, the date and time of use, etc. from the target mobile object or a computer that manages the use of the target mobile object. Based on the acquired schedule information, the use schedule determination unit 13 determines whether or not there is a use plan for the target mobile object between now and a predetermined set time in the future. It is preferable for the use schedule determination unit 13 to determine whether or not there is a use plan for the target mobile object in this manner, particularly when the target mobile object is a business vehicle or a vehicle dedicated to transporting facility batteries that can be used by persons other than the target user.

[0054] As will be explained below, while the target moving object is moving and being charged based on a plan transmitted from the plan transmitting unit 18, which will be described later, the target moving object cannot basically be moved freely from the position determined by each plan. Therefore, the use schedule determining unit 13 preferably calculates the time the target moving object will be confined to realize the plan transmitted from the plan transmitting unit 18 (hereinafter also referred to as "constraint time") based on the target information and facility information acquired by the facility information acquiring unit 15, which will be described later, and determines the time obtained by adding a predetermined margin to this confinement time as the above-mentioned set time.

[0055] The margin determination unit 14 determines whether or not the target battery mounted on the target moving object has a power supply margin or a charging margin based on the target information acquired by the target information acquisition unit 12. More specifically, if the current SOC of the target battery is greater than a predetermined power supply margin determination value, the margin determination unit 14 determines that the target battery has a power supply margin, and if the current SOC of the target battery is equal to or less than the power supply margin determination value, the margin determination unit 14 determines that the target battery does not have a power supply margin. Furthermore, if the current SOC of the target battery is equal to or less than a charging margin determination value set to a value smaller than the power supply margin determination value, the margin determination unit 14 determines that the target battery has a charging margin, and if the current SOC of the target battery is greater than the charging margin determination value, the margin determination unit 14 determines that the target battery does not have a charging margin.

[0056] Below, the processing in the facility information acquisition unit 15, travel cost calculation unit 16, user profit calculation unit 17, and plan transmission unit 18 will be explained separately for the cases where the margin determination unit 14 determines that the target battery has a power supply margin and the case where the target battery has a charging margin. If the margin determination unit 14 determines that the target battery has neither a power supply margin nor a charging margin, the target mobile object extraction unit 11 extracts other mobile objects within the management area A as target mobile objects, and the target information acquisition unit 12, use schedule determination unit 13, and margin determination unit 14 perform the above-mentioned processing for the newly determined target mobile object.

[0057] <When it is determined that there is a power supply margin> When it is determined that the target mobile object has no planned use and that the target battery has a power supply margin, the facility information acquisition unit 15 sets the target area to a range that includes the current location of the target mobile object within the management area A. Here, it is preferable that the facility information acquisition unit 15 sets the target area, for example, centered on the current location of the target mobile object and at least within a range that the target mobile object can move.

[0058] Next, the facility information acquisition unit 15 extracts, as a power supply request facility, a facility for which power supply is requested from among multiple power supply facilities (e.g., the first facility F1 and the third facility F3 in FIG. 1 , excluding charging stations S1 and S2 that are available only to authorized personnel) within the set target area, and acquires power supply request facility information related to the power supply request facility. Here, a facility for which power supply is requested refers to a facility for which the available power to supply to an electrical load is insufficient compared to the power required by the electrical load. The facility information acquisition unit 15 extracts, as a power supply request facility, a facility whose electrical load operation rate is higher than a predetermined reference operation rate, a facility for which power is not being stably supplied to an electrical load, a facility whose facility battery SOC is equal to or lower than a predetermined reference SOC, a facility whose number of facility batteries is equal to or lower than a predetermined number, and the like. The power supply request facility information acquired by the facility information acquisition unit 15 includes, for example, the location information of the power supply request facility, the unit price of electricity purchased at the power supply request facility, the number of facility batteries, the SOC of each facility battery, and information on the degree of deterioration of each facility battery.

[0059] When it is determined that the target mobile object has no use plan, the target battery has a power supply margin, and a power supply request facility is extracted within the target area, the travel cost calculation unit 16 calculates the cost borne by the target user for travel by the target mobile object between the current location and the power supply request facility as the travel power supply cost. Note that in this embodiment, a case will be described in which the travel cost calculation unit 16 calculates the cost borne by the target user when the target mobile object travels from the current location to the power supply request facility (i.e., one-way cost) as the travel power supply cost, but the present invention is not limited to this. In other words, the travel cost calculation unit 16 may calculate the cost borne by the target user when the target mobile object travels round trip between the current location and the power supply request facility (i.e., round-trip cost) as the travel power supply cost.

[0060] The travel cost calculation unit 16 calculates the mobile power supply cost defined above based on the target information, the power supply request facility information, etc. More specifically, when the target mobile object is an electric vehicle that runs using power from a target battery, the travel cost calculation unit 16 calculates the mobile power supply cost based on the electricity cost of the target mobile object, the electricity unit price of the target station of the target mobile object, the distance between the current location and the power supply request facility, etc. In other words, the travel cost calculation unit 16 calculates the mobile power supply cost assuming that the power required for the target mobile object to travel is charged at the target station. Note that when a power generation facility is provided, like the second power charging station S2, the travel cost calculation unit 16 may calculate the mobile power supply cost based on the electricity cost of the target mobile object, the electricity unit price of the target station, the distance between the current location and the power supply request facility, and the power generation status of the power generation facility. In addition, if the target moving body is one that travels using driving force generated by an internal combustion engine, the travel cost calculation unit 16 calculates the mobile power supply cost based on the fuel efficiency of the target moving body, the unit price of hydrocarbon fuel, the distance between the current location and the power supply request facility, etc.

[0061] Furthermore, if a facility usage fee (admission fee, parking fee, etc.) is set for the power supply request facility, the travel cost calculation unit 16 preferably includes this facility usage fee in the mobile power supply cost.

[0062] When it is determined that the target mobile object has no planned use, the target battery has a power supply margin, and a power supply request facility is extracted within the target area, the user benefit calculation unit 17 calculates the profit that the target user will obtain when power is supplied from the target battery to the power supply request facility as the mobile power supply profit. When power is supplied from the target battery to the first facility F1 or the third facility F3 as described above, the target user can obtain a profit according to the amount of power supplied.

[0063] The user benefit calculation unit 17 calculates the mobile power supply benefit defined as above based on the target information, the power supply request facility information, etc. More specifically, the user benefit calculation unit 17 first calculates a target SOC for the target battery after power supply at the power supply request facility. This target SOC is set to a value smaller than the current SOC of the target battery and larger than the post-mobile power supply SOC lower limit. Here, if a destination after power supply at the power supply request facility is set for the target mobile object, the user benefit calculation unit 17 may set the target SOC taking into account the distance required for travel from the power supply request facility to the destination.

[0064] The user profit calculation unit 17 calculates the amount of power that can be supplied from the target battery to the power supply requesting facility as a predicted power supply amount based on the difference between the current SOC of the target battery and the target SOC. The user profit calculation unit 17 also calculates the mobile power supply profit based on the calculated predicted power supply amount and the power purchase price at the current power supply requesting facility.

[0065] In addition, when the current location of the target mobile object is the same as the location of the target station, i.e., when the target mobile object is present at the target station, the user benefit calculation unit 17 calculates the station power supply benefit as the benefit that the target user will gain if the target battery, which is determined to have a power supply margin as described above, supplies power to the target station. As described above, the target user can also obtain a benefit if the target battery supplies power to the target station. However, as described above, the opportunities to supply power from the target battery to the target station are limited depending on the usage status of the electrical load at the target station. Therefore, when the target battery cannot currently supply power to the target station, the user benefit calculation unit 17 sets the station power supply benefit to 0.

[0066] In addition, the residual value of the target battery decreases considerably when the target battery supplies power at the power supply request facility. Therefore, the user profit calculation unit 17 may calculate the mobile power supply profit by taking into account the decrease in the residual value of the target battery caused by the power supply request facility.

[0067] When it is determined that the target mobile object has no planned use, the target battery has a power supply margin, and a power supply request facility is extracted within the target area, the plan transmission unit 18 determines whether the mobile power supply benefit calculated by the user benefit calculation unit 17 is greater than the mobile power supply cost calculated by the travel cost calculation unit 16. If the mobile power supply benefit is greater than the mobile power supply cost, the plan transmission unit 18 generates a mobile power supply plan based on the target information and the power supply request facility information, transmits this mobile power supply plan to the mobile information terminal or the target mobile object owned by the target user, and encourages the target user to provide mobile power at the power supply request facility. Here, when the mobile power supply benefit is greater than the mobile power supply cost, in other words, the mobile power supply benefit is positive even after deducting the mobile power supply cost. In other words, when the mobile power supply benefit is greater than the mobile power supply cost, from the target user's perspective, when power is supplied from the target battery to the power supply request facility, a positive benefit is obtained even after taking into account the cost of travel between the current location and the power supply request facility.

[0068] As described above, the user benefit calculation unit 17 calculates the station power supply benefit when the current location of the target mobile object is the same as the location of the target station. Therefore, if the differential benefit obtained by subtracting the mobile power supply cost from the mobile power supply benefit is greater than the station power supply benefit, the plan transmission unit 18 generates a mobile power supply plan and transmits this mobile power supply plan to the mobile information terminal owned by the target user or the target mobile object, encouraging the target user to supply power at the power supply request facility. Here, a case where the differential benefit is greater than the station power supply benefit corresponds to a case where, from the target user's perspective, it is more profitable to move the target mobile object from its current location to the power supply request facility and supply power at this destination than to supply power from the target battery to the target station without moving the target mobile object from its current location.

[0069] The mobile power supply plan includes information such as location information of the power supply requesting facility, route information between the current location and the power supply requesting facility, predicted travel time between the current location and the power supply requesting facility, predicted power supply amount, target SOC, mobile power supply cost, mobile power supply profit, station power supply profit, and predicted power supply time at the power supply requesting facility. Furthermore, when power is supplied from the target battery to the power supply requesting facility by replacing the facility battery with the target battery as described above, it is preferable that the mobile power supply plan include information necessary to identify the facility battery to be replaced and information about the SOC of the facility battery to be replaced. Therefore, by receiving such a mobile power supply plan on a mobile information terminal or a target mobile object, the target user can recognize that they can benefit by moving the target mobile object to the power supply requesting facility and supplying power at the destination. Assuming that the target mobile object is an unmanned autonomous vehicle, it is preferable that the plan transmission unit 18 include information necessary for the target mobile object to move unmanned and automatically from its current location to the power supply requesting facility (e.g., location information of the power supply requesting facility and route information between the current location and the power supply requesting facility) in the mobile power supply plan.

[0070] Furthermore, the unit price of electricity purchased at the power supply request facility may vary depending on the time period. In this case, it is preferable that the plan transmission unit 18 include the mobile power supply profit for each time period in the mobile power supply plan. This allows the target user to select the most profitable time period to supply power at the power supply request facility. Furthermore, when the target user selects a time period to supply power at the power supply request facility in this way, the target user may have to wait near the power supply request facility until the power supply request facility starts supplying power. In anticipation of such a case, the plan transmission unit 18 may extract facilities that are located near the power supply request facility and have inexpensive parking as recommended relay points, and include information about these recommended relay points in the mobile power supply plan.

[0071] Furthermore, as described above, if the target moving body is an unmanned autonomous vehicle, it can basically move and supply power at any time regardless of the target user's convenience. Therefore, if the target moving body is an unmanned autonomous vehicle and the power purchase price at the power supply request facility varies depending on the time of day, it is preferable that the plan transmission unit 18 include in the mobile power supply plan information required to supply power during the time period when the mobile power supply profit is maximized (e.g., the departure time from the current location and the arrival time at the power supply request facility, etc.).

[0072] Note that the demand for power at the power supply requesting facility changes from moment to moment. Therefore, as described above, after the plan transmission unit 18 transmits the mobile power supply plan, the differential profit or the difference between the differential profit and the station power supply profit may become negative. Therefore, even after transmitting the mobile power supply plan, the user profit calculation unit 17 continues to sequentially calculate the mobile power supply profit based on the latest power supply requesting facility information. Preferably, the plan transmission unit 18 transmits a cancellation notice for the notified mobile power supply plan to the mobile information terminal owned by the target user or the target mobile body if the differential profit or the difference between the differential profit and the station power supply profit becomes negative while the target mobile body is moving toward the power supply requesting facility. This minimizes the disadvantage suffered by the target user.

[0073] Furthermore, when transmitting the mobile power supply plan to the mobile information terminal or the target mobile body of the target user, the plan transmission unit 18 may transmit a reservation for use of the power supply request facility by the target user to the power supply request facility and automatically acquire the reservation for use of the power supply request facility. Furthermore, when the plan transmission unit 18 cannot acquire a reservation for use of the power supply request facility or when it is unclear whether the target user can use the power supply request facility, the plan transmission unit 18 may transmit a mobile power supply plan related to another power supply request facility.

[0074] Furthermore, the residual value of the target battery varies depending on the discharge rate of the target battery at the power supply request facility. Therefore, if the target user can select the discharge rate of the target battery at the power supply request facility, the plan transmission unit 18 preferably includes information on the decrease in the residual value of the target battery at each discharge rate in the mobile power supply plan. This allows the target user to select a discharge rate taking into account the decrease in the residual value of the target battery.

[0075] <When it is determined that there is enough charge left> When it is determined that the target mobile object has no planned use and that the target battery has a charge margin, the facility information acquisition unit 15 sets the target area to a range within the management area A that includes the current location of the target mobile object. Here, it is preferable that the facility information acquisition unit 15 sets the target area, for example, centered on the current location of the target mobile object and within at least a range within which the target mobile object can move. Furthermore, it is preferable that the range of the target area set by the facility information acquisition unit 15 when it is determined that the target battery has a charge margin is narrower than the range of the target area set when it is determined that the target battery has a power supply margin.

[0076] Next, the facility information acquisition unit 15 extracts a facility where charging is requested from among multiple charging facilities within the set target area (e.g., the second facility F2 and the third facility F3 in FIG. 1 , excluding charging stations S1 and S2 that are available only to authorized personnel), as a charging request facility, and acquires charging request facility information related to the facility. Here, a facility where charging is requested refers to a facility where the power generated by its power generation equipment is in excess of the power required by the facility battery. The facility information acquisition unit 15 extracts, as charging request facilities, facilities where the SOC of the facility battery is higher than a predetermined reference SOC, facilities where the number of facility batteries is equal to or less than a predetermined number, and facilities where the operation rate of the power generation equipment is higher than a predetermined reference operation rate. The charging request facility information acquired by the facility information acquisition unit 15 includes, for example, location information of the charging request facility, the electricity selling price at the charging request facility, the number of facility batteries, the SOC of each facility battery, and information on the degree of deterioration of each facility battery.

[0077] When it is determined that the target mobile object has no planned use, that the target battery has charging margin, and a charging request facility is extracted within the target area, the travel cost calculation unit 16 calculates, as the travel charging cost, the cost borne by the target user for travel by the target mobile object between the current location and the charging request facility. Note that in this embodiment, a case will be described in which the travel cost calculation unit 16 calculates, as the travel charging cost, the cost borne by the target user when the target mobile object travels from the current location to the charging request facility (i.e., one-way cost), but the present invention is not limited to this. In other words, the travel cost calculation unit 16 may calculate, as the travel charging cost, the cost borne by the target user when the target mobile object travels round trip between the current location and the charging request facility (i.e., round-trip cost).

[0078] The travel cost calculation unit 16 calculates the mobile charging cost defined above based on the target information, charging request facility information, etc. More specifically, when the target mobile object is an electric vehicle, the travel cost calculation unit 16 calculates the mobile charging cost based on the electricity cost of the target mobile object, the electricity unit price of the target station of the target mobile object, and the distance between the current location and the charging request facility, etc. In other words, the travel cost calculation unit 16 calculates the mobile charging cost using a procedure similar to that for the mobile power supply cost described above, assuming that the power required for the target mobile object to travel is charged at the target station. Furthermore, when the target mobile object travels using driving force generated by an internal combustion engine, the travel cost calculation unit 16 calculates the mobile charging cost using a procedure similar to that for the mobile power supply cost described above.

[0079] Furthermore, if a facility usage fee is set for the charging request facility, it is preferable that the travel cost calculation unit 16 include this facility usage fee in the travel charging cost.

[0080] When it is determined that the target mobile body is not scheduled to be used, the target battery is determined to have charging capacity, and a charging request facility is extracted within the target area, the user benefit calculation unit 17 calculates the benefit that the target user will gain when charging the target battery from the charging request facility as the mobile charging benefit.

[0081] As described above, when the target battery is charged from the second facility F2 or the third facility F3, the target user must pay a fee according to the amount of charged energy. The target user must also pay a fee according to the amount of charged energy when the target battery is charged from the target station. Therefore, the user benefit calculation unit 17 calculates the difference between the cost borne by the target user when charging the target battery from the target station and the cost borne by the target user when charging the target battery from the charging request facility as the mobile charging benefit.

[0082] More specifically, the user benefit calculation unit 17 first calculates a target SOC for the target battery after charging at the charging request facility. This target SOC is set to a value greater than the target battery's current SOC and less than the post-mobile charging SOC upper limit. Furthermore, the user benefit calculation unit 17 calculates the amount of power that can be supplied from the charging request facility to the target battery as a predicted amount of charging power based on the difference between the target battery's current SOC and the target SOC. Furthermore, the user benefit calculation unit 17 calculates the cost that the target user will incur if the predicted amount of charging power is supplied from the target station to the target battery based on the electricity rate at the target station. Furthermore, the user benefit calculation unit 17 calculates the cost that the target user will incur if the predicted amount of charging power is supplied from the charging request facility to the target battery based on the electricity selling price at the charging request facility. Furthermore, the user benefit calculation unit 17 calculates the mobile charging benefit by subtracting the cost that the target user will incur if the target user were to charge at the charging request facility from the cost that the target user would incur if the target battery were to charge at the target station calculated as described above.

[0083] In addition, the residual value of the target battery decreases considerably when power is supplied at the charging request facility. Therefore, the user profit calculation unit 17 may calculate the mobile charging profit by taking into account the decrease in the residual value of the target battery due to charging at the charging request facility.

[0084] When it is determined that the target mobile object has no planned use, that the target battery has charging capacity, and a charging request facility is extracted within the target area, the plan transmission unit 18 determines whether the mobile charging benefit calculated by the user benefit calculation unit 17 is greater than the mobile charging cost calculated by the travel cost calculation unit 16. When the mobile charging benefit is greater than the mobile charging cost, the plan transmission unit 18 generates a mobile charging plan based on the target information acquired by the target information acquisition unit 12 and the charging request facility information acquired by the facility information acquisition unit 15, and transmits this mobile charging plan to the mobile information terminal or the target mobile object owned by the target user. Here, when the mobile charging benefit is greater than the mobile charging cost, in other words, when the mobile charging benefit is positive even after deducting the mobile charging cost. In other words, when the mobile charging benefit is greater than the mobile charging cost, from the target user's perspective, when the target battery is charged from the charging request facility, a positive benefit is obtained even after taking into account the cost of travel between the current location and the charging request facility.

[0085] The mobile charging plan includes information such as location information of the charging request facility, route information between the current location and the charging request facility, predicted travel time between the current location and the charging request facility, predicted charging energy, target SOC, mobile charging cost, mobile charging benefit, and predicted charging time at the charging request facility. Furthermore, when charging the target battery from the charging request facility by replacing the facility battery with the target battery as described above, it is preferable to include in the mobile charging plan information necessary to identify the facility battery to be replaced and information about the SOC of the facility battery to be replaced. Therefore, by receiving such a mobile charging plan on a mobile information terminal or a target mobile object, the target user can recognize that they can benefit by moving the target mobile object to the charging request facility and charging at the destination. As with the mobile power supply plan described above, it is preferable that the plan transmission unit 18 include in the mobile charging plan information necessary for the target mobile object to automatically and unmannedly move from its current location to the charging request facility (e.g., location information of the charging request facility and route information between the current location and the charging request facility).

[0086] Furthermore, the electricity selling price at the charging request facility may vary depending on the time of day. In this case, it is preferable that the plan transmission unit 18 include the mobile charging profit for each time period in the mobile charging plan. This allows the target user to select the most profitable time period to charge at the charging request facility. Furthermore, when the target user selects a time period to charge at the charging request facility in this way, the target user may have to wait near the charging request facility until charging starts at the charging request facility. In anticipation of such a case, the plan transmission unit 18 may extract a facility that is located near the charging request facility and has an inexpensive parking lot as a recommended relay point, and may include information about this recommended relay point in the mobile charging plan.

[0087] Furthermore, as described above, if the target mobile body is an unmanned autonomous vehicle, it is basically possible for the target user to travel and charge at any time they like, regardless of their own convenience. Therefore, if the target mobile body is an unmanned autonomous vehicle and the electricity selling price at the charging request facility varies depending on the time of day, it is preferable that the plan transmission unit 18 include in the mobile charging plan information required to perform charging at a time period when the mobile charging profit is maximized (for example, the departure time from the current location and the arrival time at the charging request facility, etc.).

[0088] Note that the demand for electricity at the charging request facility changes from moment to moment. Therefore, as described above, after the plan transmission unit 18 transmits the mobile charging plan, the difference between the mobile charging profit and the mobile charging cost may become negative. Therefore, it is preferable that the user profit calculation unit 17 continues to calculate the mobile charging profit sequentially based on the latest charging request facility information even after transmitting the mobile charging plan, and that the plan transmission unit 18 transmits a cancellation notice for the notified mobile charging plan to the mobile information terminal owned by the target user or the target mobile body if the difference between the mobile charging profit and the mobile charging cost becomes negative while the target mobile body is moving toward the charging request facility. This minimizes the disadvantage suffered by the target user.

[0089] Furthermore, when transmitting the mobile charging plan to the mobile information terminal or the target mobile body of the target user, the plan transmission unit 18 may transmit a reservation for use of the charging request facility by the target user to the charging request facility, and automatically acquire the reservation for use of the charging request facility. Furthermore, when the plan transmission unit 18 cannot acquire a reservation for use of the charging request facility or when it is unclear whether the target user can use the charging request facility, the plan transmission unit 18 may transmit a mobile power supply plan related to another charging request facility.

[0090] Furthermore, the residual value of the target battery varies depending on the charging speed of the target battery at the charging request facility. Therefore, if the target user can select the charging speed of the target battery at the charging request facility, the plan transmission unit 18 preferably includes information on the decrease in the residual value of the target battery at each charging speed in the mobile charging plan. This allows the target user to select a charging speed taking into account the decrease in the residual value of the target battery.

[0091] The power charging and supply management system 1 according to this embodiment has the following advantages. (1) The target information acquisition unit 12 acquires target information regarding the current location of the target mobile body and the state of the target battery, the facility information acquisition unit 15 extracts a power supply request facility from multiple facilities around the current target mobile body (i.e., within the target area) and acquires power supply request facility information regarding this power supply request facility, the surplus determination unit 14 determines whether there is a power supply surplus from the target battery, the travel cost calculation unit 16 calculates the cost borne by the target user for travel between the current location of the target mobile body and the power supply request facility as the mobile power supply cost, and the user profit calculation unit 17 calculates the profit that the target user will gain when power is supplied from the target battery to the power supply request facility as the mobile power supply profit. Furthermore, if the target battery is determined to have a power supply margin and the mobile power supply benefit is greater than the mobile power supply cost, i.e., if it is determined that the target user can benefit by moving the target mobile object from its current location to the power supply request facility and supplying power at the destination, the plan transmission unit 18 transmits a mobile power supply plan generated based on the target information and the power supply request facility information to the target user's mobile information terminal or the target mobile object. This allows the target user to recognize that they can benefit by moving the target mobile object to the power supply request facility and supplying power at the destination, thereby encouraging the target mobile object to move to the power supply request facility and supply power at the destination, thereby benefiting the target user. Furthermore, by encouraging power supply at power supply request facilities where power demand is high in this way, unnecessary demand responses can be avoided, thereby contributing to improved energy efficiency.

[0092] (2) When the current location of the target mobile object is the same as the location of the target station, the user benefit calculation unit 17 calculates the benefit that the target user will gain when power is supplied from the target battery to the target station as the station power supply benefit, and when the difference profit obtained by subtracting the mobile power supply cost from the mobile power supply benefit is greater than the station power supply benefit, i.e., when a greater benefit can be obtained by moving the target mobile object to the power supply request facility and supplying power at this destination than by supplying power to the target station without moving the target mobile object from the target station, the plan transmission unit 18 transmits the mobile power supply plan to the target user's mobile information terminal or the target mobile object. This makes it possible to more reliably bring benefits to the target user.

[0093] (3) When the target mobile object is an electric vehicle that runs using power from the target battery, the travel cost calculation unit 16 calculates the mobile power supply cost based on the electricity cost of the target mobile object and the electricity unit price of the target station. This can improve the accuracy of the profit that the user can obtain when power is supplied based on the mobile power supply plan.

[0094] (4) The use schedule determination unit 13 determines whether or not there is a use plan for the target mobile object from the present until a predetermined time after the detention time, and the plan transmission unit 18 transmits a mobile power supply plan to the target user's mobile information terminal or the target mobile object if it is determined that the target battery has a power supply margin, that the target mobile object is not scheduled for use, and the differential profit is greater than the station power supply profit. This allows the target user to benefit from the time when the target mobile object is not in use, even if the target mobile object is intended to be used by unspecified persons other than the target user.

[0095] (5) When the target moving body is an unmanned autonomous vehicle, the plan transmission unit 18 transmits to the target moving body a mobile power supply plan including information necessary for automatically moving the target moving body from its current location to the power supply request facility, thereby enabling the target moving body to automatically move to the power supply request facility and receive power at the destination.

[0096] (6) The demand for power at a power supply request facility changes continuously. Therefore, the user benefit calculation unit 17 sequentially calculates the mobile power supply benefit based on the latest power supply request facility information. If the differential benefit becomes smaller than the station power supply benefit while the target mobile object is moving toward the power supply request facility, the plan transmission unit 18 transmits a cancellation notice for the notified mobile power supply plan to the target terminal or target mobile object. This makes it possible to minimize the disadvantages incurred by the target user.

[0097] (7) The target information acquisition unit 12 acquires target information regarding the current location of the target mobile object and the state of the target battery. The facility information acquisition unit 15 extracts a charging request facility from multiple facilities around the current target mobile object (i.e., within the target area) and acquires charging request facility information regarding the charging request facility. The margin determination unit 14 determines whether the target battery has a charging margin. The travel cost calculation unit 16 calculates the cost borne by the target user for travel between the current location of the target mobile object and the charging request facility as a mobile charging cost. The user benefit calculation unit 17 calculates the benefit the target user will gain by charging the target battery from the charging request facility as a mobile charging benefit. Furthermore, if it is determined that the target battery has a charging margin and the mobile charging benefit is greater than the mobile charging cost, i.e., if it is determined that the target user will gain a benefit by moving the target mobile object from its current location to the charging request facility and charging at this destination, the plan transmission unit 18 transmits a mobile charging plan generated based on the target information and the charging request facility information to the target user's mobile information terminal or the target mobile object. This allows the target user to recognize that they can benefit by moving the target mobile body to the charging request facility and charging at the destination, which encourages the target mobile body to move to the charging request facility and charge at the destination, thereby bringing benefits to the target user. Furthermore, by encouraging charging at charging request facilities where charging demand is high in this way, unnecessary demand response can be avoided, which can contribute to improving energy efficiency.

[0098] (8) The user benefit calculation unit 17 calculates the mobile charging benefit by subtracting the cost that the target user will incur when charging the target battery from the charging request facility from the cost that the target user will incur when charging the target battery from the target station. This makes it possible to more reliably provide benefits to the target user.

[0099] (9) If the target mobile object is an electric vehicle that runs using the power of the target battery, the travel cost calculation unit 16 calculates the mobile charging cost based on the electricity cost of the target mobile object and the electricity unit price of the target station. This can improve the accuracy of the profit that the user can obtain when charging based on the mobile charging plan.

[0100] (10) The usage schedule determination unit 13 determines whether or not there is a usage plan for the target mobile object from the present until a predetermined time from now, and the plan transmission unit 18 transmits a mobile charging plan to the target user's mobile information terminal or the target mobile object if it is determined that the target battery has a charge margin, that the target mobile object is not scheduled for use, and that the mobile charging benefit is greater than the mobile charging cost. This allows the target user to benefit from the time when the target mobile object is not in use, even if the target mobile object is intended to be used by unspecified persons other than the target user.

[0101] (11) When the target mobile object is an unmanned autonomous vehicle, the plan transmission unit 18 transmits to the target mobile object a mobile charging plan including information necessary for automatically moving the mobile object from its current location to the charging request facility. This allows the target mobile object to automatically move to the charging request facility and charge at the destination.

[0102] (12) The demand for electricity at a charging request facility changes continuously. Therefore, the user benefit calculation unit 17 continuously calculates the mobile charging benefit based on the latest charging request facility information. If the mobile charging benefit becomes less than the mobile charging cost while the target mobile body is moving toward the charging request facility, the plan transmission unit 18 transmits a cancellation notification for the notified mobile charging plan to the target terminal or the target mobile body. This minimizes the disadvantages incurred by the target user.

[0103] Although one embodiment of the present invention has been described above, the present invention is not limited to this, and the detailed configuration may be modified as appropriate within the scope of the spirit of the present invention.

[0104] For example, in the above embodiment, the charging and power supply management system 1 that manages the charging and power supply of the on-board battery is configured as a server that can communicate with a mobile object equipped with an on-board battery, but the present invention is not limited to this. All or some of the components of the charging and power supply management system may be configured as an on-board computer that is installed in the mobile object.

[0105] In a charging facility where both power supply and charging can be performed at the same facility, such as the third facility F3 in FIG. 1, power supply and charging may be alternately performed without the target mobile object being moved from the facility. Furthermore, in such a charging facility, the target user may be able to obtain greater benefits by supplying power (or charging) and then waiting until the electricity selling price (or electricity purchasing price) at the charging facility drops (or rises) before charging (or supplying power). In such a case, the plan transmission unit 18 may transmit a mobile charging plan to the target user's mobile information terminal or the target mobile object, which allows the target mobile object to alternately supply power and charge at the charging facility. In particular, when the target mobile object is an unmanned autonomous vehicle, transmitting the above-described mobile charging plan is advantageous because it allows the target user to repeatedly charge and charge without tying up the target user's time.
