Description

Technical Field

[0001] The present invention relates to a charging and power supply management system, and more particularly, to a charging and power supply management system for managing the charging and power supply of a power storage device mounted on a mobile object. Background Art

[0002] In recent years, research and development related to charging and powering mobile devices equipped with secondary batteries that contribute to achieving energy efficiency has been underway to ensure that more people have access to affordable, reliable, sustainable, and advanced energy.

[0003] Most electric vehicles, which run on electricity stored in onboard secondary batteries (hereinafter referred to as "onboard batteries"), have both a charging function and a power supply function. The charging function charges the onboard batteries using electricity supplied from an external power source, and the power supply function supplies the electricity stored in the onboard batteries to external loads. Furthermore, in recent years, electric vehicle users have been able to charge or supply their vehicles not only at home but also at various facilities at their destinations (for example, see Patent Document 1).

[0006] Patent Document 1: Japanese Patent Application Laid-Open No. 2020-162395 Summary of the Invention

[0007] [Problems to be solved by the invention]

[0008] However, at power generation facilities (i.e., facilities equipped with power generation equipment and charging equipment that uses the power generated by the power generation equipment to charge the vehicle's battery) that have surplus power for some reason, users may be able to charge their vehicle's battery at a lower cost than if they were charging at home. Furthermore, at power supply facilities (i.e., facilities equipped with electrical loads and power supply equipment that supplies power from the vehicle's battery to the loads) that have insufficient power for some reason, users may be able to sell electricity at a higher price than if they were supplying power from the vehicle's battery to their home.

[0009] When various charging and power supply facilities exist besides one's home, the user's profit is expected to vary depending on the location where charging and power supply are performed. However, until now, there has been little research into where users can maximize their profit through charging and power supply.

[0010] An object of the present invention is to provide a charging and power supply management system that manages charging and power supply of a power storage device to provide benefits to users of mobile objects equipped with the power storage device and further contribute to improving energy efficiency.

[0024] (Effects of the Invention)

[0025] (1) In the present invention, a target information acquisition unit acquires target information related to the current position of a target mobile body and the state of a power storage device. A facility information acquisition unit extracts a power supply request facility from a plurality of facilities surrounding the current target mobile body (i.e., within a target area) and acquires power supply request facility information related to the power supply request facility. A margin determination unit determines whether the power storage device has a power supply margin. A movement fee calculation unit calculates the fee incurred by the target user due to the movement of the target mobile body between the current position and the power supply request facility as a movement power supply fee. A user benefit calculation unit calculates the benefit earned by the target user when power is supplied from the power storage device to the power supply request facility as a movement power supply benefit. Furthermore, when it is determined that the power storage device has a power supply margin and the movement power supply benefit is greater than the movement power supply fee, that is, when it is determined that the target user can obtain benefits by moving the target mobile body from the current position to the power supply request facility and supplying power at the movement destination, the plan transmission unit transmits a movement power supply plan generated based on the target information and the power supply request facility information to the target user's target terminal or the target mobile body. This allows the target user to recognize that there is a benefit to be gained by moving the target mobile object toward the power supply request facility and providing power at the destination. This encourages the target mobile object to move toward the power supply request facility and provide power at the destination, further benefiting the target user. Furthermore, by encouraging power supply at facilities with increased power demand in this manner, unnecessary demand responses can be avoided, thereby contributing to improved energy efficiency.

[0026] (2) In the present invention, when the current location and the location of the target site specified for each target mobile body are the same, the user benefit calculation unit calculates the benefit obtained by the target user when power is supplied from the power storage device to the target site as the site power supply benefit. The plan transmission unit transmits the mobile power supply plan to the target terminal or target mobile body when the difference between the mobile power supply benefit and the mobile power supply fee is greater than the site power supply benefit, that is, when a greater benefit can be obtained by moving the target mobile body to the power supply request facility and supplying power at the destination than when the target site is supplied without moving the target mobile body from the target site. This makes it possible to more reliably provide benefits to the target user.

[0027] (3) Electric vehicle users often charge their power storage devices at specific destinations. Therefore, when the target mobile object is an electric vehicle powered by a power storage device, the mobility fee calculation unit calculates the mobility power supply fee based on the target mobile object's electricity rate and the unit price of electricity at the destination. This improves the accuracy of user revenue when power is supplied based on the mobility power supply plan.

[0028] (4) In the present invention, the usage plan determination unit determines whether the target mobile object has a usage plan between the present and a specific time in the future. The plan transmission unit transmits the mobile power supply plan to the target terminal or target mobile object when it is determined that the power storage device has power supply margin, the target mobile object has no usage plan, and the difference profit is greater than the site power supply profit. Thus, even if the target mobile object is assumed to be used by an unspecified person other than the target user, the target user can benefit from the period when the target mobile object is not used.

[0029] (5) In the present invention, when the target mobile object is an unmanned autonomous vehicle, the plan transmitting unit transmits a mobile power supply plan to the target mobile object, the mobile power supply plan including information required to automatically move the mobile object from its current location to the power supply request facility. This allows the target mobile object to automatically move to the power supply request facility and be powered at the destination.

[0030] (6) The power demand at the power request facility changes sequentially. Therefore, the user benefit calculation unit sequentially calculates the mobile power supply benefit based on the latest power request facility information. The plan sending unit sends a cancellation notice for the already notified mobile power supply plan to the target terminal or target mobile object when the difference benefit is less than the site power supply benefit while the target mobile object is moving toward the power request facility. This minimizes the disadvantages to the target user.

[0031] (7) In the present invention, the target information acquisition unit acquires target information related to the current position of the target mobile body and the state of the power storage device. The facility information acquisition unit extracts a charging request facility from a plurality of facilities around the current target mobile body (i.e., within the target area) and acquires charging request facility information related to the charging request facility. The margin determination unit determines whether the power storage device has a charging margin. The movement fee calculation unit calculates the fee incurred by the target user due to the movement of the target mobile body between the current position and the charging request facility as the movement charging fee. The user benefit calculation unit calculates the benefit obtained by the target user when the power storage device is charged at the charging request facility as the movement charging benefit. Furthermore, when it is determined that the power storage device has a charging margin and the movement charging benefit is greater than the movement charging fee, that is, when it can be determined that the target user can obtain benefits by moving the target mobile body from the current position toward the charging request facility and charging at the movement destination, the plan transmission unit transmits the movement charging plan generated based on the target information and the charging request facility information to the target user's target terminal or target mobile body. This allows the target user to recognize that there is a benefit to be gained by moving the target mobile object to the charging request facility and charging at the destination. This encourages the target mobile object to move to the charging request facility and charge at the destination, further benefiting the target user. Furthermore, by encouraging charging at facilities with increasing charging demand in this way, unnecessary demand responses can be avoided, thereby contributing to improved energy efficiency.

[0032] (8) In the present invention, the user benefit calculation unit calculates the mobile charging benefit by subtracting the cost borne by the target user when the power storage device is charged at the target site from the cost borne by the target user when the power storage device is charged at the charging request facility. This allows the target user to more reliably benefit.

[0033] (9) In the present invention, when the target mobile object is an electric vehicle that runs on power from a power storage device, the mobile fee calculation unit calculates the mobile charging fee based on the target mobile object's electricity rate and the unit price of electricity at the target station. This improves the accuracy of the user's profit when charging based on the mobile charging plan.

[0034] (10) In the present invention, the usage plan determination unit determines whether there is a usage plan for the target mobile object between the present and a specific time in the future. The plan transmission unit transmits the mobile charging plan to the target terminal or target mobile object when it is determined that the power storage device has a sufficient charge capacity, the target mobile object has no usage plan, and the mobile charging benefit is greater than the mobile charging fee. Thus, even if the target mobile object is assumed to be used by an unspecified person other than the target user, the target user can benefit from the period when the target mobile object is not used.

[0035] (11) In the present invention, when the target mobile object is an unmanned autonomous vehicle, the plan transmitting unit transmits a mobile charging plan to the target mobile object, the mobile charging plan including information necessary for the mobile object to automatically move from its current location to the charging request facility. This allows the target mobile object to automatically move to the charging request facility and be charged at the destination.

[0036] (12) The power demand at the charging request facility changes sequentially. Therefore, the user benefit calculation unit sequentially calculates the mobile charging benefit based on the latest charging request facility information. The plan sending unit sends a cancellation notice for the mobile charging plan that has been notified to the target terminal or target mobile body when the mobile charging benefit is less than the mobile charging fee while the target mobile body is moving toward the charging request facility. This minimizes the disadvantages to the target user. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Figure 1 This is a diagram schematically illustrating a charging and power supply management system and a portion of a management area of the charging and power supply management system according to an embodiment of the present invention.

[0038] Figure 2 This is a functional block diagram showing the configuration of a charging and power supply management system. DETAILED DESCRIPTION

[0039] Hereinafter, a charging and power supply management system according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0040] Figure 1 This diagram schematically illustrates the configuration of a portion of a charging and power supply management system 1 and a management area A of the charging and power supply management system 1 according to this embodiment. Within management area A, there are multiple facilities F1, F2, F3, ..., and charging and power supply stations S1, S2, ..., capable of charging or supplying power to multiple mobile objects M1, M2, M3, M4, M5, ..., or secondary batteries B1, B2, B3, B4, B5, ..., which serve as power storage devices mounted on these mobile objects (hereinafter referred to as "onboard batteries") .

[0041] The first facility F1 is a power supply facility having electrical loads, multiple secondary batteries (hereinafter, to distinguish them from vehicle-mounted batteries B1, B2, etc., the secondary batteries installed on the facility will also be referred to as "facility batteries"), and power supply equipment that supplies power supplied from these facility batteries or vehicle-mounted batteries to the above-mentioned electrical loads.

[0042] Specifically, a user of a third mobile object M3 located in the first facility F1 can connect their onboard battery B3 to the power supply equipment, thereby supplying the electricity stored in the onboard battery B3 to the electrical loads of the first facility F1. By supplying power to the first facility F1 from their onboard battery B3 in this manner, the user of the third mobile object M3 earns a profit proportional to the product of the amount of power supplied from the onboard battery B3 to the first facility F1 (hereinafter referred to as "supplied power") and the electricity purchase price specified in the first facility F1. Furthermore, the act of a mobile object user replacing their onboard battery with a facility battery with less remaining power will be referred to as "powering." The electricity purchase price in the first facility F1 varies depending on factors such as the power demand in the first facility F1, the remaining power in the facility battery, and the number of facility batteries.

[0043] The second facility F2 is a charging facility having a power generation facility that generates electricity using renewable energy such as solar power or wind power, a plurality of facility batteries, and a charging facility that charges these facility batteries or a vehicle battery using the power generated by the power generation facility.

[0044] Specifically, users of the fourth mobile object M4 located in the second facility F2 can charge their onboard battery B4 by connecting it to a charging device. When charging their onboard battery B4 from the second facility F2 in this manner, the user of the fourth mobile object M4 must pay a fee to the second facility F2 proportional to the amount of electricity supplied from the second facility F2 to the onboard battery B4 (hereinafter referred to as "charged electricity") multiplied by the electricity sales price specified in the second facility F2. Furthermore, the act of replacing an onboard battery with a facility battery with a higher remaining charge will also be referred to as "charging." The electricity sales price in the second facility F2 varies depending on factors such as the power demand within the second facility F2, the remaining charge in the facility battery, and the number of facility batteries.

[0045] The third facility F3 is a charging and power supply facility equipped with electrical loads, multiple facility batteries, power supply equipment, power generation equipment, and charging equipment. Specifically, users of the fifth mobile object M5 located within the third facility F3 can supply power to the third facility F3 from their onboard battery B5, or charge their onboard battery B5 from the third facility F3. Furthermore, similar to the aforementioned facilities F1 and F2, users of the mobile object M5 earn revenue when supplying power, but pay fees when charging.

[0046] The first charging and power supply station S1 is the home of the user of the first mobile object M1. The first charging and power supply station S1 is a charging and power supply facility equipped with electrical loads, power supply equipment, and charging equipment. In other words, the user of the first mobile object M1 can park the first mobile object M1 in their home parking lot and supply power from their vehicle's battery B1 to the first charging and power supply station S1, or charge their vehicle's battery B1 at the first charging and power supply station S1.

[0047] When the user of the first mobile body M1 charges the vehicle battery B1 from the first charging and supplying station S1 in this manner, he needs to pay a fee to the power company that is proportional to the product of the amount of electricity charged to the vehicle battery B1 from the first charging and supplying station S1 and the unit price of electricity specified in the first charging and supplying station S1.

[0048] Furthermore, by supplying power from the vehicle battery B1 to the first charging and supply station S1 in this manner, the user of the first mobile object M1 can earn a profit proportional to the amount of power supplied from the vehicle battery B1 to the first charging and supply station S1. Here, the profit earned by the user of the first mobile object M1 from supplying power from the vehicle battery B1 to the first charging and supply station S1 corresponds, for example, to the reduction in the user's charges to the electric power company for supplying power from the vehicle battery B1 to the first charging and supply station S1. In this way, the user of the first mobile object M1 can earn a profit by supplying power from the vehicle battery B1 to the first charging and supply station S1, but the opportunities for supplying power are limited depending on the usage of the electrical loads at the first charging and supply station S1.

[0049] The second charging and power supply station S2 is the home of the user of the second mobile object M2. The second charging and power supply station S2 is a charging and power supply facility equipped with electrical loads, power supply equipment, charging equipment, and power generation equipment. In other words, the user of the second mobile object M2 can park the second mobile object M2 in their home parking lot and supply power from their vehicle's battery B2 to the second charging and power supply station S2, or charge their vehicle's battery B2 at the second charging and power supply station S2.

[0050] When the user of the second mobile body M2 charges the vehicle battery B2 from the second charging and supplying station S2 in this manner, he needs to pay the power company a fee corresponding to the amount of electricity charged to the vehicle battery B2 from the second charging and supplying station S2, the unit price of electricity specified in the second charging and supplying station S2, and the power generation status of the power generation equipment at that time.

[0051] Furthermore, by supplying power from the onboard battery B2 to the second charging and supply station S2 in this manner, the user of the second mobile object M2 can earn a profit proportional to the amount of power supplied from the onboard battery B2 to the second charging and supply station S2. Here, the profit earned by the user of the second mobile object M2 from supplying power from the onboard battery B2 to the second charging and supply station S2 corresponds, for example, to the reduction in the user's charges to the electric power company for supplying power from the onboard battery B2 to the second charging and supply station S2. In this way, the user of the second mobile object M2 can earn a profit by supplying power from the onboard battery B2 to the second charging and supply station S2, but the opportunities for supplying power may be limited depending on the usage of the electrical loads at the second charging and supply station S2 or the power generation status of the power generation equipment.

[0052] In the following description, the mobile objects M1, M2, ... are electric vehicles that run on electricity stored in onboard batteries B1, B2, ..., and are the private vehicles of the users of the mobile objects M1, M2, ..., but the present invention is not limited to this. The mobile objects may also include internal combustion engines that consume hydrocarbon fuels to generate driving force. Furthermore, the mobile objects are not limited to the users' private vehicles; they may also be business vehicles used by the users or persons other than the users for the users' business (e.g., MaaS vehicles or ride-sharing vehicles). Furthermore, the mobile objects may also be dedicated facility battery transport vehicles that transport or replace multiple facility batteries between the aforementioned multiple facilities F1, F2, F3, ....

[0053] The charging and power supply management system 1 extracts one or more target mobile bodies from a plurality of mobile bodies M1, M2, ... existing in a management area A, sends a plan related to the charging and power supply of the on-board battery of the target mobile body to a mobile information terminal held by a user of the target mobile body (hereinafter also referred to as the "target user") or the target mobile body, and reminds charging and power supply according to the plan, thereby managing the charging and power supply of the on-board battery of the target mobile body.

[0054] The charging and power supply management system 1 is composed of one or more computers, which are communicatively connected via base stations to the facilities F1, F2, F3, ..., charging and power supply stations S1, S2, ..., mobile objects M1, M2, ..., and mobile information processing terminals owned by users of each mobile object M1, M2, ... (hereinafter collectively referred to as "area terminals") within the management area A. More specifically, the charging and power supply management system 1 is composed of servers or edge servers, which are connected to the multiple facilities F1, F2, F3, ..., etc. via base stations, a network core, and the internet. The edge servers are connected to the multiple area terminals via base stations and a multi-access edge computing (MEC) core.

[0055] Figure 2 This is a functional block diagram illustrating the configuration of the charging and power supply management system 1. The charging and power supply management system 1 includes a target mobile object extraction unit 11, a target information acquisition unit 12, a usage plan determination unit 13, a margin determination unit 14, a facility information acquisition unit 15, a travel fee calculation unit 16, a user benefit calculation unit 17, and a plan transmission unit 18. The functions of blocks 11 through 18 described below are implemented by the charging and power supply management system 1, which is a computer, executing a program stored on a storage medium (not shown).

[0056] The target moving object extraction unit 11 extracts one or more moving objects M1 , M2 , . . . existing in the management area A as a target moving object.

[0057] The target information acquisition unit 12 acquires target information from the target mobile object, the mobile information terminal held by the target user, the target station, etc. The target information includes information related to the current position of the target mobile object extracted by the target mobile object extraction unit 11, the state of the on-board battery (hereinafter also referred to as "target battery") loaded on the target mobile object, and the target station (i.e., the location of the target mobile object) of the target mobile object. Figure 1 In this example, the first charging and power supply station S1 corresponds to the target station of the first mobile body M1, and the second charging and power supply station S2 corresponds to the target station of the second mobile body M2. The target information acquired by the target information acquisition unit 12 includes information related to the current location of the target mobile body, performance information related to the performance of the target mobile body (i.e., electricity cost or fuel consumption), category information related to the type of the target mobile body (i.e., home vehicle, business vehicle, and facility battery transport vehicle), the number of target batteries mounted on the target mobile body, the current remaining capacity (SOC [%]) of each target battery expressed as a percentage, the lower limit SOC of each target battery after mobile power supply, the upper limit SOC of each target battery after mobile charging, information related to the degree of deterioration of each target battery, the operating rate of the electrical load at the target station, the power generation status of the power generation equipment at the target station, the unit price of electricity at the target station, and the location of the target station. The target information acquisition unit 12 transmits the acquired target information to the margin determination unit 14 , the travel fee calculation unit 16 , the user benefit calculation unit 17 , the plan transmission unit 18 and the like described below.

[0058] Here, the post-mobile power supply SOC lower limit corresponds to the lower limit of the target battery's SOC after powering at the destination facility according to the mobile power supply plan described below. Furthermore, the post-mobile charging SOC upper limit corresponds to the upper limit of the target battery's SOC after charging at the destination facility according to the mobile charging plan described below. These post-mobile power supply SOC lower limit and post-mobile charging SOC upper limit are, for example, predefined by the destination user to prevent degradation of the target battery.

[0059] The usage plan determination unit 13 obtains scheduling information from a computer that manages the target mobile object or its use. The scheduling information specifies the vehicles, dates, and times of use of the target mobile object. Furthermore, based on the obtained scheduling information, the usage plan determination unit 13 determines whether there is a usage plan for the target mobile object between the current time and a specific set time. The usage plan determination unit 13 preferably determines whether there is a usage plan for the target mobile object in this manner, particularly when the target mobile object is a business vehicle or a dedicated vehicle for facility battery transport that can be used by persons other than the target user.

[0060] As described below, while the target mobile object is moving, charging, and supplying power based on a plan transmitted from the plan transmitting unit 18, the target mobile object is essentially unable to move freely from the position specified by each plan. Therefore, the use plan determination unit 13 preferably calculates the time (hereinafter referred to as "constraint time") required for the target mobile object to implement the plan transmitted from the plan transmitting unit 18 based on the target information and the facility information acquired by the facility information acquiring unit 15, etc., and determines the time obtained by adding a specified margin to the constraint time as the set time.

[0061] Based on the target information acquired by the target information acquisition unit 12, the margin determination unit 14 determines whether the target battery mounted on the target mobile object has a power supply margin or a charge margin. More specifically, the margin determination unit 14 determines that the target battery has a power supply margin when the current SOC of the target battery is greater than a specific power supply margin determination value, and determines that the target battery does not have a power supply margin when the current SOC of the target battery is less than the power supply margin determination value. Furthermore, the margin determination unit 14 determines that the target battery has a charge margin when the current SOC of the target battery is less than a charge margin determination value set to a value smaller than the power supply margin determination value, and determines that the target battery does not have a charge margin when the current SOC of the target battery is greater than the charge margin determination value.

[0062] The following describes the processing performed by the facility information acquisition unit 15, travel fee calculation unit 16, user benefit calculation unit 17, and plan transmission unit 18, specifically when the margin determination unit 14 determines that the target battery has a power supply margin and when the target battery has a charge margin. Furthermore, if the margin determination unit 14 determines that the target battery has neither a power supply margin nor a charge margin, the target mobile object extraction unit 11 extracts another mobile object within the management area A as a target mobile object, and the target information acquisition unit 12, usage plan determination unit 13, and margin determination unit 14 execute the aforementioned processing for the newly specified target mobile object.

[0063] <Situations where power supply margin is determined>

[0064] When the facility information acquisition unit 15 determines that the target mobile object has no usage plan and that the target battery has sufficient power supply, it sets the target area to a range that includes the current position of the target mobile object in the management area A. Here, the facility information acquisition unit 15 preferably sets the target area, for example, centered around the current position of the target mobile object and within at least the range within which the target mobile object can move.

[0065] Next, the facility information acquisition unit 15 obtains information from a plurality of power supply facilities (e.g. Figure 1 From the first and third facilities (excluding charging and power supply stations S1 and S2, which are only accessible to specific users), the facility requesting power is extracted as a power-requesting facility, and power-requesting facility information related to the power-requesting facility is obtained. Here, a power-requesting facility refers to a facility that can supply insufficient power to the electric load relative to the power requested by the electric load. The facility information acquisition unit 15 extracts, as power-requesting facilities, facilities whose electric load operating rates exceed a specific baseline operating rate, facilities that are not stably supplying power to the electric load, facilities whose facility batteries have a SOC below a specific baseline SOC, and facilities whose facility batteries have a specific number or less. The power-requesting facility information acquired by the facility information acquisition unit 15 includes, for example, location information of the power-requesting facility, information regarding the unit price of electricity purchased at the power-requesting facility, the number of facility batteries, the SOC of each facility battery, and the degree of deterioration of each facility battery.

[0066] When the target mobile object is determined to have no usage plans, the target battery has sufficient power, and a power supply request facility is identified within the target area, the travel fee calculation unit 16 calculates the cost incurred by the target user for moving the target mobile object between its current location and the power supply request facility as the travel power supply fee. While this embodiment describes a scenario in which the travel fee calculation unit 16 calculates the cost incurred by the target user when the target mobile object moves from its current location to the power supply request facility (i.e., a one-way fee) as the travel power supply fee, the present invention is not limited to this. Specifically, the travel fee calculation unit 16 may also calculate the cost incurred by the target user when the target mobile object moves back and forth between its current location and the power supply request facility (i.e., a round-trip fee) as the travel power supply fee.

[0067] The travel cost calculation unit 16 calculates the travel power supply cost, as defined above, based on the target information and the power supply request facility information. More specifically, if the target mobile object is an electric vehicle running on power from a target battery, the travel cost calculation unit 16 calculates the travel power supply cost based on the target mobile object's electricity cost, the unit price of electricity at the target station, and the distance between the current location and the power supply request facility. In other words, the travel cost calculation unit 16 calculates the travel power supply cost assuming that the target mobile object will be charged with the electricity required for movement at the target station. Alternatively, if a power generation facility is provided, as at the second charging and power supply station S2, the travel cost calculation unit 16 may also calculate the travel power supply cost based on the target mobile object's electricity cost, the unit price of electricity at 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. Furthermore, if the target mobile object is running on driving force generated by an internal combustion engine, the travel cost calculation unit 16 calculates the travel power supply cost based on the target mobile object's fuel consumption, the unit price of hydrocarbon fuels, and the distance between the current location and the power supply request facility.

[0068] Furthermore, when a facility usage fee (entrance fee, parking fee, etc.) is stipulated for the power supply request facility, the travel fee calculation unit 16 preferably includes the facility usage fee in the travel power supply fee.

[0069] When the target mobile object is determined to have no usage plans, the target battery has sufficient power supply, and a power supply request facility is selected within the target area, the user benefit calculation unit 17 calculates the benefit the target user would receive if power were supplied from the target battery to the power supply request facility as the mobile power supply benefit. As described above, when power is supplied from the target battery to the first facility F1 or the third facility F3, the target user receives a benefit corresponding to the amount of power supplied.

[0070] The user benefit calculation unit 17 calculates the mobile power supply benefit defined above based on the target information and the power supply request facility information. More specifically, the user benefit calculation unit 17 first calculates the target SOC of the target battery after power supply at the power supply request facility. This target SOC is set to a value less than the current SOC of the target battery and greater than the lower limit of the SOC after power supply during mobile operation. When setting a destination for the target mobile object after power supply at the power supply request facility, the user benefit calculation unit 17 may also consider the portion required to travel from the power supply request facility to the destination.

[0071] Furthermore, the user benefit calculation unit 17 calculates the amount of power that can be supplied from the target battery to the power supply request facility based on the difference between the target battery's current SOC and the target SOC, as the predicted power supply amount. Furthermore, the user benefit calculation unit 17 calculates the mobile power supply benefit based on the calculated predicted power supply amount and the current unit price of electricity purchased at the power supply request facility.

[0072] Furthermore, when the current location of the target mobile object is the same as the location of its target station, that is, when the target mobile object is at its target station, the user benefit calculation unit 17 calculates the benefit earned by the target user when power is supplied to the target station from the target battery determined to have sufficient power supply margin as described above. As described above, the target user can also earn a benefit when power is supplied to the target station from the target battery. However, as described above, the opportunity to supply power to the target station from the target battery is limited depending on the usage of the electrical load at the target station. Therefore, when power cannot be supplied to the target station from the target battery, the user benefit calculation unit 17 sets the site power supply benefit to zero.

[0073] Furthermore, the remaining value of the target battery is significantly reduced by power supply at the power supply request facility. Therefore, the user profit calculation unit 17 may also calculate the mobile power supply profit by taking into account the reduction in the remaining value of the target battery due to power supply at the power supply request facility.

[0074] If the target mobile object has no usage plan, the target battery has sufficient power, and a power supply request facility is selected within the target area, the plan sending 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 sending unit 18 generates a mobile power supply plan based on the target information and the power supply request facility information, and sends the mobile power supply plan to the target user's mobile information terminal or the target mobile object, encouraging the target user to move to the power supply request facility for power supply. Here, if the mobile power supply benefit is greater than the mobile power supply cost, it means that even after deducting the mobile power supply cost, the mobile power supply benefit remains positive. In other words, if the mobile power supply benefit is greater than the mobile power supply cost, the target user can still obtain a positive benefit from supplying power from the target battery to the power supply request facility, even after taking into account the cost of traveling between the current location and the power supply request facility.

[0075] Furthermore, as described above, the user benefit calculation unit 17 calculates the site power supply benefit when the current location of the target mobile object is the same as the location of its target site. Therefore, when the difference between the mobile power supply benefit and the mobile power supply fee is greater than the site power supply benefit, the plan transmission unit 18 generates a mobile power supply plan and transmits this mobile power supply plan to the target user's mobile information terminal or the target mobile object, encouraging the target user to move to the power supply request facility for power supply. Here, the situation where the difference is greater than the site power supply benefit means that, from the perspective of the target user, moving the target mobile object from its current location to the power supply request facility and then supplying power at the destination will yield greater benefits than if power is supplied from the target battery to the target site without moving the target mobile object from its current location.

[0076] Here, the mobile power supply plan includes information related to the location information of the power supply request facility, route information between the current location and the power supply request facility, predicted travel time between the current location and the power supply request facility, predicted power supply amount, target SOC, mobile power supply fee, mobile power supply profit, site power supply profit, and predicted power supply time at the power supply request facility. Furthermore, as described above, when power is supplied from a target battery to the power supply request facility by exchanging a facility battery with a target battery, the mobile power supply plan preferably includes information required to specify the facility battery to be replaced or information related to the SOC of the facility battery to be replaced. Therefore, by receiving such a mobile power supply plan at a mobile information terminal or a target mobile object, the target user can recognize that by moving the target mobile object to the power supply request facility and supplying power at the destination, a profit can be obtained. Furthermore, assuming that the target mobile object is an unmanned autonomous vehicle, the plan transmitting unit 18 preferably includes information required for unmanned and autonomous movement of the target mobile object from its current location to the power supply request facility (e.g., location information of the power supply request facility and route information between the current location and the power supply request facility) in the mobile power supply plan.

[0077] In addition, the unit price of electricity purchased at the power supply request facility sometimes varies depending on the time period. In this case, the plan sending unit 18 preferably includes the mobile power supply benefits of each time period in the mobile power supply plan. Thereby, the target user can select the time period in which the maximum benefit is obtained and perform power supply at the power supply request facility. In addition, as described above, when the target user selects the time period and performs power supply at the power supply request facility, the target user sometimes needs to wait near the power supply request facility until power supply starts at the power supply request facility. Assuming this situation, the plan sending unit 18 can also extract a facility that exists near the power supply request facility and has a cheap parking lot as a recommended transit point, and include information related to the recommended transit point in the mobile power supply plan.

[0078] Furthermore, as described above, when the target mobile object is an unmanned autonomous vehicle, power can be provided during travel at a desired time, essentially without regard to the convenience of the target user. Therefore, when the target mobile object is an unmanned autonomous vehicle and the electricity purchase price at the power supply request facility varies depending on the time of day, the plan transmitting unit 18 preferably includes in the mobile power supply plan information necessary for providing power during the time period when the mobile power supply benefit is maximized (e.g., departure time from the current location and arrival time at the power supply request facility).

[0079] In addition, the power demand at the power supply request facility changes all the time. Therefore, as described above, after the plan sending unit 18 sends the mobile power supply plan, the above-mentioned difference profit or the difference between the above-mentioned difference profit and the site power supply profit may sometimes turn negative. Therefore, even after the mobile power supply plan is sent, the user profit calculation unit 17 still calculates the mobile power supply profit in sequence based on the latest power supply request facility information. During the period when the target mobile body moves toward the power supply request facility, when the above-mentioned difference profit or the difference between the above-mentioned difference profit and the site power supply profit turns negative, the plan sending unit 18 preferably sends a cancellation notice for the notified mobile power supply plan to the mobile information terminal held by the target user or the target mobile body. In this way, the disadvantages suffered by the target user can be kept to a minimum.

[0080] Furthermore, when the plan sending unit 18 sends the mobile power supply plan to the target user's mobile information terminal or target mobile object, it may also send the target user's reservation for the power supply request facility to the power supply request facility and automatically obtain the reservation for the power supply request facility. Furthermore, if the plan sending unit 18 cannot obtain the reservation for the power supply request facility or if it is unclear whether the target user can use the power supply request facility, it may send another mobile power supply plan related to the power supply request facility.

[0081] Furthermore, the target battery's remaining value varies depending on the target battery's discharge rate at the power supply request facility. Therefore, when the target user can select the target battery's discharge rate at the power supply request facility, the plan transmitting unit 18 preferably includes information regarding the decrease in the target battery's remaining value 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 target battery's remaining value.

[0082] <When it is determined that there is sufficient charge>

[0083] When the facility information acquisition unit 15 determines that the target mobile object has no planned use and that the target battery has sufficient charge, it sets a target area within a range encompassing the current location of the target mobile object within management area A. Here, the facility information acquisition unit 15 preferably sets the target area, for example, centered around the current location of the target mobile object and within a range at least as large as the target mobile object's movable range. Furthermore, the facility information acquisition unit 15 preferably sets the target area when determining that the target battery has sufficient charge to operate narrower than the target area set when determining that the target battery has sufficient power to operate.

[0084] Next, the facility information acquisition unit 15 obtains information from a plurality of charging facilities (e.g. Figure 1 From the second facility F2 and the third facility F3 (excluding charging and power supply stations S1 and S2 that can only be used by specific people), the facility for which charging is requested is extracted as the charging request facility, and charging request facility information related to the charging request facility is obtained. Here, the charging request facility refers to a facility where the power generation equipment has surplus power relative to the power requested in the facility battery. The facility information acquisition unit 15 extracts, as charging request facilities, facilities whose facility batteries have an SOC greater than a specific reference SOC, facilities whose facility batteries have a specific number or less, and facilities whose power generation equipment operating rate is greater than a specific reference operating rate. In addition, the charging request facility information acquired by the facility information acquisition unit 15 includes, for example, location information of the charging request facility, information related to the unit price of electricity sold at the charging request facility, the number of facility batteries, the SOC of each facility battery, and the degree of deterioration of each facility battery.

[0085] When the target mobile object is determined to have no usage plans, the target battery has sufficient charge, and a charging facility is identified within the target area, the travel fee calculation unit 16 calculates the cost incurred by the target user for moving the target mobile object between its current location and the charging facility as the travel charging fee. While this embodiment describes a scenario in which the travel fee calculation unit 16 calculates the cost incurred by the target user when the target mobile object moves from its current location to the charging facility (i.e., a one-way fee) as the travel charging fee, the present invention is not limited to this. Specifically, the travel fee calculation unit 16 may also calculate the cost incurred by the target user when the target mobile object moves back and forth between its current location and the charging facility (i.e., a round-trip fee) as the travel charging fee.

[0086] The travel cost calculation unit 16 calculates the travel charging cost, as defined above, based on the target information and the requested charging facility information. More specifically, when the target moving object is an electric vehicle, the travel cost calculation unit 16 calculates the travel charging cost based on the target moving object's electricity rate, the unit price of electricity at the target moving object's target station, and the distance between the current location and the requested charging facility. In other words, the travel cost calculation unit 16 assumes that the target moving object will be charged with the electricity required for movement at the target station and calculates the travel charging cost using the same procedure as the travel power supply cost described above. Furthermore, when the target moving object is traveling using the driving force generated by its internal combustion engine, the travel cost calculation unit 16 also calculates the travel charging cost using the same procedure as the travel power supply cost described above.

[0087] Furthermore, when a facility usage fee is specified for the charging request facility, the travel fee calculation unit 16 preferably includes the facility usage fee in the travel charging fee.

[0088] When the target mobile object is determined to have no usage plan, the target battery has sufficient charge, and a charging request facility is extracted within the target area, the user profit calculation unit 17 calculates the profit obtained by the target user when the target battery is charged at the charging request facility as the mobile charging profit.

[0089] As described above, when charging the target battery from the second facility F2 or the third facility F3, the target user pays a fee corresponding to the amount of electricity charged. Furthermore, when charging the target battery from the target station, the target user also pays a fee corresponding to the amount of electricity charged. Therefore, the user benefit calculation unit 17 calculates the difference between the fee borne by the target user when charging the target battery from the target station and the fee borne by the target user when charging the target battery from the charge request facility as the mobile charging benefit.

[0090] More specifically, the user profit calculation unit 17 first calculates the target SOC of the target battery after charging at the charging request facility. This target SOC is set to a value greater than the current SOC of the target battery and less than the upper limit of the SOC after mobile charging. Furthermore, based on the difference between the current SOC of the target battery and the target SOC, the user profit calculation unit 17 calculates the amount of electricity that can be supplied from the charging request facility to the target battery as the predicted charging amount. Furthermore, based on the unit price of electricity at the target site, the user profit calculation unit 17 calculates the cost to the target user assuming the predicted charging amount is supplied from the target site to the target battery. Furthermore, based on the unit price of electricity sold at the charging request facility, the user profit calculation unit 17 calculates the cost to the target user if the predicted charging amount is supplied from the charging request facility to the target battery. Furthermore, the user profit calculation unit 17 calculates the mobile charging profit by subtracting the cost to the target user when charging at the charging request facility from the cost to the target user when charging at the target site, calculated in this manner.

[0091] Furthermore, the remaining value of the target battery decreases significantly due to power supply at the charging request facility. Therefore, the user profit calculation unit 17 may also calculate the mobile charging profit by taking into account the decrease in the remaining value of the target battery due to charging at the charging request facility.

[0092] If the plan transmission unit 18 determines that the target mobile object has no usage plan, that the target battery has sufficient charge, and that a charging facility has been selected within the target area, it then determines whether the mobile charging benefit calculated by the user benefit calculation unit 17 is greater than the mobile charging fee calculated by the travel fee calculation unit 16. If the mobile charging benefit is greater than the mobile charging fee, 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 facility information acquired by the facility information acquisition unit 15, and transmits the mobile charging plan to the mobile information terminal held by the target user or the target mobile object. Here, the situation where the mobile charging benefit is greater than the mobile charging fee corresponds to the situation where the mobile charging benefit remains positive even after deducting the mobile charging fee. In other words, the situation where the mobile charging benefit is greater than the mobile charging fee corresponds to the situation where, from the perspective of the target user, a positive benefit can be obtained when charging the target battery at the charging facility, even after taking into account the cost of traveling between the current location and the charging facility.

[0093] Here, the mobile charging plan includes information related to the 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 power, target SOC, mobile charging fee, mobile charging benefits, and predicted charging time at the charging request facility. Furthermore, as described above, when charging the target battery from the charging request facility by swapping the facility battery with the target battery, the mobile charging plan preferably includes information required to specify the facility battery to be swapped, or information related to the SOC of the facility battery to be swapped. Therefore, by receiving such a mobile charging plan on a mobile information terminal or the target mobile object, the target user can recognize that by moving the target mobile object to the charging request facility and charging at the destination, benefits can be obtained. Furthermore, similar to the mobile power supply plan described above, the plan transmitting unit 18 preferably includes information required for unmanned and autonomous movement of the target mobile object 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).

[0094] In addition, the unit price of electricity sold at the charging request facility sometimes varies depending on the time period. In this case, the plan sending unit 18 preferably includes the mobile charging benefits within each time period in the mobile charging plan. Thereby, the target user can select the time period in which the maximum benefit is obtained and charge at the charging request facility. In addition, when the target user selects the time period in this way and charges at the charging request facility, the target user sometimes needs to wait near the charging request facility until charging starts at the charging request facility. Assuming this situation, the plan sending unit 18 can also extract a facility that exists near the charging request facility and has a cheap parking lot as a recommended transfer point, and include information related to the recommended transfer point in the mobile charging plan.

[0095] Furthermore, as described above, when the target mobile object is an unmanned autonomous vehicle, charging can be performed while traveling at a desired time, with little regard for the convenience of the target user. Therefore, when the target mobile object is an unmanned autonomous vehicle and the electricity price at the requested charging facility varies depending on the time of day, the plan transmitting unit 18 preferably includes in the mobile charging plan information necessary for charging during the time period when mobile charging benefits are maximized (e.g., departure time from the current location and arrival time at the requested charging facility).

[0096] In addition, the power demand at the charging request facility changes all the time. Therefore, as described above, after the plan sending unit 18 sends the mobile charging plan, the difference between the mobile charging benefit and the mobile charging fee may sometimes turn negative. Therefore, even after the mobile charging plan is sent, the user benefit calculation unit 17 continues to calculate the mobile charging benefit based on the latest charging request facility information. While the target mobile body is moving toward the charging request facility, when the difference between the mobile charging benefit and the mobile charging fee turns negative, the plan sending unit 18 preferably sends a cancellation notice for the notified mobile charging plan to the mobile information terminal held by the target user or the target mobile body. In this way, the disadvantages suffered by the target user can be kept to a minimum.

[0097] Furthermore, when sending the mobile charging plan to the target user's mobile information terminal or target mobile object, the plan sending unit 18 may also send the target user's reservation for the requested charging facility to the requested charging facility and automatically obtain the reservation for the requested charging facility. Furthermore, if the plan sending unit 18 cannot obtain the reservation for the requested charging facility or if it is unclear whether the target user can use the requested charging facility, it may send another mobile power supply plan related to the requested charging facility.

[0098] Furthermore, the target battery's remaining value varies depending on the target battery's charging speed at the charging request facility. Therefore, when the target user can select the target battery's charging speed at the charging request facility, the plan transmitting unit 18 preferably includes information regarding the decrease in the target battery's remaining value 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 target battery's remaining value.

[0099] According to the charging and power supply management system 1 of this embodiment, the following effects are achieved.

[0100] (1) The target information acquisition unit 12 acquires target information related to the current position 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 a plurality of facilities surrounding the current target mobile body (i.e., within the target area) and acquires power supply request facility information related to the power supply request facility. The margin determination unit 14 determines whether the target battery has power supply margin. The movement fee calculation unit 16 calculates the fee incurred by the target user due to the movement of the target mobile body between the current position and the power supply request facility as the movement power supply fee. The user benefit calculation unit 17 calculates the benefit obtained by the target user when power is supplied from the target battery to the power supply request facility as the movement power supply benefit. Furthermore, when it is determined that the target battery has power supply margin and the movement power supply benefit is greater than the movement power supply fee, that is, when it is determined that the target user can obtain benefits by moving the target mobile body from the current position to the power supply request facility and supplying power at the movement destination, the plan transmission unit 18 transmits the movement 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 body. This allows the target user to recognize that there is a benefit to be gained by moving the target mobile object toward the power supply request facility and providing power at the destination. This encourages the target mobile object to move toward the power supply request facility and provide power at the destination, further benefiting the target user. Furthermore, by encouraging power supply at the power supply request facility where power demand is increasing in this manner, unnecessary demand responses can be avoided, thereby contributing to improved energy efficiency.

[0101] (2) When the current location of the target mobile body and the location of the target site are the same, the user benefit calculation unit 17 calculates the benefit that the target user will receive when power is supplied from the target battery to the target site as the site power supply benefit. When the difference between the mobile power supply benefit and the mobile power supply fee is greater than the site power supply benefit, that is, when a greater benefit can be obtained by moving the target mobile body to the power supply request facility and supplying power to the destination than by supplying power to the target site without moving the target mobile body from the target site, the plan transmission unit 18 transmits the mobile power supply plan to the target user's mobile information terminal or the target mobile body. This makes it possible to more reliably provide benefits to the target user.

[0102] (3) When the target mobile object is an electric vehicle that runs on the power of the target battery, the mobile fee calculation unit 16 calculates the mobile power supply fee based on the electricity rate of the target mobile object and the unit price of electricity at the target station. This improves the accuracy of the user's profit when power is supplied according to the mobile power supply plan.

[0103] (4) The usage plan determination unit 13 determines whether there is a usage plan for the target mobile object between the present and a specific future time constraint. If it is determined that the target battery has power supply margin, the target mobile object has no usage plan, and the difference profit is greater than the site power supply profit, the plan transmission unit 18 transmits the mobile power supply plan to the target mobile information terminal or the target mobile object. In this way, even if the target mobile object is assumed to be used by an unspecified person other than the target user, the target user can benefit from the period when the target mobile object is not used.

[0104] (5) When the target mobile object is an unmanned autonomous vehicle, the plan transmitting unit 18 transmits a mobile power supply plan to the target mobile object, the mobile power supply plan including information required to automatically move the mobile object from its current location to the power supply request facility. This allows the target mobile object to automatically move to the power supply request facility and be powered at the destination.

[0105] (6) The power demand at the power request facility changes sequentially. Therefore, the user benefit calculation unit 17 sequentially calculates the mobile power supply benefit based on the latest power request facility information. The plan sending unit 18 sends a cancellation notice for the already notified mobile power supply plan to the target terminal or target mobile object when the difference benefit is less than the site power supply benefit while the target mobile object is moving toward the power request facility. This minimizes the disadvantages to the target user.

[0106] (7) The target information acquisition unit 12 acquires target information related to the current position of the target mobile body and the state of the target battery. The facility information acquisition unit 15 extracts a charging request facility from a plurality of facilities around the current target mobile body (i.e., within the target area) and acquires charging request facility information related to the charging request facility. The margin determination unit 14 determines whether the target battery has a charging margin. The movement fee calculation unit 16 calculates the fee incurred by the target user due to the movement of the target mobile body between the current position and the charging request facility as the movement charging fee. The user benefit calculation unit 17 calculates the benefit obtained by the target user when the target battery is charged at the charging request facility as the movement charging benefit. In addition, when it is determined that the target battery has a charging margin and the movement charging benefit is greater than the movement charging fee, that is, when it can be determined that the target user can obtain benefits by moving the target mobile body from the current position toward the charging request facility and charging at the movement destination, the plan sending unit 18 sends the movement 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 body. This allows the target user to recognize that there is a benefit to be gained by moving the target mobile object to the charging request facility and charging at the destination. This encourages the target mobile object to move to the charging request facility and charge at the destination, further benefiting the target user. Furthermore, by encouraging charging at the charging request facility where charging demand is increasing in this manner, unnecessary demand responses can be avoided, thereby contributing to improved energy efficiency.

[0107] (8) The user benefit calculation unit 17 calculates the mobile charging benefit by subtracting the cost borne by the target user when charging the target battery at the target station from the cost borne by the target user when charging the target battery at the charging request facility. This can more reliably bring benefits to the target user.

[0108] (9) When the target mobile object is an electric vehicle that runs on the power of the target battery, the mobile fee calculation unit 16 calculates the mobile charging fee based on the electricity rate of the target mobile object and the unit price of electricity at the target station. This improves the accuracy of the user's profit when charging based on the mobile charging plan.

[0109] (10) The usage plan determination unit 13 determines whether there is a usage plan for the target mobile object between the present and a specific future time constraint. The plan transmission unit 18 transmits the 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 sufficient charge, the target mobile object has no usage plan, and the mobile charging benefit is greater than the mobile charging fee. Thus, even if the target mobile object is assumed to be used by an unspecified person other than the target user, the target user can benefit from the period when the target mobile object is not used.

[0110] (11) When the target mobile object is an unmanned autonomous vehicle, the plan transmitting unit 18 transmits a mobile charging plan to the target mobile object, the mobile charging plan including information necessary for the mobile object to automatically move from its current location to the charging request facility. This allows the target mobile object to automatically move to the charging request facility and be charged at the destination.

[0111] (12) The power demand at the charging request facility changes sequentially. Therefore, the user benefit calculation unit 17 sequentially calculates the mobile charging benefit based on the latest charging request facility information. The plan sending unit 18 sends a cancellation notification for the mobile charging plan that has been notified to the target terminal or target mobile object when the mobile charging benefit is less than the mobile charging fee while the target mobile object is moving toward the charging request facility. This minimizes the disadvantages to the target user.

[0112] While one embodiment of the present invention has been described above, the present invention is not limited thereto and the detailed configuration may be appropriately modified within the scope of the gist of the present invention.

[0113] For example, in the above embodiment, the charging and power supply management system 1 that manages the charging and power supply of the vehicle-mounted battery is configured as a server capable of communicating with the mobile object equipped with the vehicle-mounted battery. However, the present invention is not limited to this. All or part of the components of the charging and power supply management system may also be configured as an onboard computer installed on the mobile object.

[0114] However, in a Figure 1 In charging and power supply facilities that can both power and charge at the same facility, as in the third facility F3, alternating power supply and charging can sometimes be performed without requiring the target mobile object to move from the same facility. Furthermore, in such charging and power supply facilities, the target user can sometimes achieve greater benefits by waiting until the unit price of electricity sold (or purchased) at the same charging and power supply facility decreases (or increases) before charging (or supplying). In this case, the plan transmission unit 18 can also transmit a mobile charging and power supply plan for alternating power supply and charging at the same charging and power supply facility to the target user's mobile information terminal or target mobile object. In particular, when the target mobile object is an unmanned autonomous vehicle, the advantages of transmitting such a mobile charging and power supply plan are significant, as repeated charging and power supply can be performed without constraining the target user's time.
