Description

[Technical field]

[0001] The present invention relates to an electric power transfer system and an electric power transfer method for transferring electric power (electrical energy) stored in a battery of a mobile body. [Background technology]

[0002] In recent years, an increasing number of households have installed photovoltaic power generation equipment (hereinafter referred to as "PV") on their homes in order to take advantage of the Feed-in Tariff Scheme for renewable energy (hereinafter referred to as the "FIT Scheme"). However, as PV becomes more widespread, the purchase price of renewable energy is decreasing year by year, and due to the recent rise in the unit price of commercial electricity, an increasing number of households are abandoning the FIT Scheme and instead consuming electricity generated by PV (hereinafter referred to as "PV electricity") for their own use. In addition, many households are unable to use all of their PV electricity at home and are discarding it. On the other hand, amid the global movement toward carbon neutrality, an increasing number of companies are purchasing expensive electricity derived from renewable energy sources in order to contribute to environmental measures.

[0003] Patent Document 1 proposes an electric power system that uses a storage battery mounted on a mobile object to sell electric power generated from renewable energy. Patent Document 1 describes that "the control unit determines the upper limit electric power amount based on a first parameter included in the charge / discharge history information" of the electric power storage device mounted on the mobile object, and that "the parameter corresponds to the amount of electric power derived from renewable energy among the remaining capacity of the storage battery." Patent Document 1 also describes that "the control unit may permit the electric power storage device to sell electric power when a second parameter included in the charge / discharge history information is 0 points." The second parameter is a parameter corresponding to the amount of electric power derived from exhaustible energy. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 7136785 Summary of the Invention [Problem to be solved by the invention]

[0005] In the power system described in Patent Document 1, when a power storage device (storage battery) of a mobile object is charged by a charging device installed at home, information that can identify whether the power charged to the power storage device is power derived from renewable energy or not is stored in the power storage device.

[0006] However, charging facilities generally installed in towns do not distinguish whether the electricity being charged into the battery of a mobile vehicle is derived from renewable energy sources. Therefore, even if a home charging device (EV charging / discharging device) identifies that the battery's electricity is derived from renewable energy sources, when a mobile vehicle's battery is charged at a charging facility in town, it is not possible to distinguish whether the electricity being charged into the battery is derived from renewable energy sources. For example, consider a case where a seller charges a battery of a mobile body with PV power using a charging device (EV charging / discharging device) installed at a home or other location that can identify the origin of the charging power, and then sells the power charged in the battery to a buyer. If the seller uses up the PV power in the battery before selling the power and charges the battery at a charging facility outside the home, the buyer will not be able to know the origin of the power charged in the battery.

[0007] In light of the above situation, there was a need for a method that would enable a buyer to identify the source of the electricity charged in the battery of a seller's mobile vehicle (the type of energy used to generate electricity), even if the seller charges the battery of the mobile vehicle at a charging facility outside the seller's home. [Means for solving the problem]

[0008] In order to solve the above problems, one aspect of the present invention is a power transfer system that transfers power using a storage battery mounted on a mobile body, and is equipped with a power supply feasibility determination device that compares a cumulative number of times the storage battery is charged when the storage battery is charged with power derived from renewable energy and a cumulative number of times the storage battery is charged when a power receiving device that receives power from the storage battery requests power supply from the storage battery, and determines whether to allow power supply from the storage battery to the power receiving device based on the comparison result. Effect of the Invention

[0009] According to at least one aspect of the present invention, even if the seller charges the storage battery of a mobile body at a charging facility other than the seller's home, the buyer can identify the source of the electricity charged to the storage battery of the seller's mobile body (the type of energy used to generate electricity). Problems, configurations and effects other than those described above will become apparent from the following description of the embodiments. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, examples of modes for carrying out the present invention (hereinafter, referred to as "embodiments") will be described with reference to the accompanying drawings.

[0012] In this specification and the accompanying drawings, identical or similar components are given the same reference numerals, and duplicate explanations may be omitted, or only differences may be explained. In addition, when there are multiple identical or similar components, they may be explained with different subscripts added to the same reference numerals. In addition, when it is not necessary to distinguish between these multiple components, the subscripts may be omitted. The number of each component may be singular or plural, unless otherwise specified.

[0013] In addition, for example, various names such as "XX information", "XX table", "XX list", and "XX list" are interchangeable. In addition, when explaining identification information, expressions such as "identification information", "name", and "ID" are used, and these are interchangeable.

[0014] <One embodiment of the present invention> An electric power transfer system using a battery (storage battery) mounted on a mobile object according to one embodiment of the present invention will be described with reference to Figs. 1 to 12. The electric power transfer system according to this embodiment is a system that charges a battery mounted on a mobile object with electric power and sells the electric power to a consumer. The mobile object is, for example, a vehicle such as an electric vehicle (EV). Electric vehicles also include automobiles such as plug-in hybrid vehicles that are mounted with a relatively large capacity battery and can supply electric power to the outside.

[0015] [Overall configuration of the power transfer system] First, the overall configuration of an electric power transfer system according to an embodiment of the present invention will be described with reference to FIG.

[0016] FIG. 1 is a schematic diagram showing an example of the overall configuration of an electric power transfer system according to this embodiment. The power transfer system 1 includes a solar panel 11 (photovoltaic power generation device (PV)) installed in a home 10 or the like, and a charging / discharging device 20 that charges and discharges a battery using power generated by the solar panel 11 or commercial power 2. The battery is, for example, a battery 31 mounted on an electric vehicle (hereinafter, referred to as "EV") 30, and a stationary battery 13 (see FIG. 2).

[0017] A distribution board 12 is installed in a home 10. The distribution board 12 is connected to a power distribution line supported by a utility pole and to a charging / discharging device 20. The distribution board 12 distributes power supplied from commercial power 2 or the charging / discharging device 20 to household equipment (electrical equipment, outlets, etc.).

[0018] The charging / discharging device 20 has a function of charging the battery 31 of the EV 30 and a function of extracting power from the battery 31. The battery 31 is a storage battery used for receiving and sending (selling) power. The power stored in the battery 31 is referred to as "EV power." The EV 30 records the history of charging and discharging the battery 31 as operation data 32. The EV 30 then transmits the operation data 32 to the operation status management server 110 via OTA (Over The Air).

[0019] The operation status management server 110 is, for example, a server managed and operated by an automobile manufacturer. The operation status management server 110 receives and records operation data 32 transmitted by vehicles such as EVs 30 manufactured by the company, thereby managing the operation status (driving and charging / discharging information) of the vehicles.

[0020] The operation data 32 includes at least information on charging and discharging the battery 31. The information on charging and discharging the battery 31 is, for example, the cumulative number of times the battery 31 has been charged and the cumulative number of times it has been discharged since the EV 30 was manufactured. The cumulative number of times the battery 31 has been charged and the cumulative number of times it has been discharged are managed in association with identification information of the battery 31 (or the EV 30). The operation data 32 also includes information on the running of the EV 30.

[0021] An information processing device 40 is connected to the charging / discharging device 20. For example, the information processing device 40 is provided in the home 10. The information processing device 40 transmits information (charging / discharging data) relating to the charging / discharging of the battery 31 by the charging / discharging device 20 to the operation server 100 via a network N such as the Internet. Note that the charging / discharging device 20 may output information relating to the charging / discharging of the stationary battery 13, in addition to the battery 31, to the information processing device 40.

[0022] The operation server 100 is a server that manages the operation of the entire power transfer system 1 that utilizes the battery 31 of the EV 30. When the operation server 100 receives information related to the charging and discharging of the battery 31 from the charging and discharging device 20, it issues a two-dimensional code based on the information related to the charging and discharging and transmits it to the mobile terminal 50 of the user or owner of the EV 30. The two-dimensional code can be transmitted using e-mail or a communication application such as a social network service (SNS).

[0023] The two-dimensional code is used for the purpose of authenticating the legitimate user or owner of the EV 30 when the charging power of the battery 31 of the EV 30 is sold. At least the license plate information of the EV 30 that is equipped with the battery 31 charged with PV-derived power in the home 10 is recorded in the two-dimensional code. The license plate information is a number such as a vehicle registration plate number that is given to identify the vehicle.

[0024] The operation server 100 has data on the registrant and contact information associated with the license plate information of the vehicle in advance, and transmits a two-dimensional code to the registrant's contact information after charging. Here, the registrant is the user or owner of the EV 30, and the contact information is the email address or SNS account of the mobile terminal 50, etc. In the following, an example in which the user sells the charging power of the battery 31 will be described, but the same applies to the owner.

[0025] The operation server 100 receives information about the operation status of the vehicle (particularly, the status related to charging) from the operation status management server 110 via the network N. Then, when the operation server 100 receives a transmission request for the cumulative number of times the battery 31 mounted on the EV 30 has been charged from the local terminal 80, the operation server 100 transmits the cumulative number of times the battery has been charged to the local terminal 80.

[0026] The power transfer system 1 also includes a power selling device 70 installed in a commercial facility 60 for selling EV power, and a local terminal 80 for transmitting and receiving data between the power selling device 70. The commercial facility 60 is an example of a buyer (consumer) of the power charged in the battery 31 of the EV 30. A camera 90 is connected to the local terminal 80 for capturing an image of the license plate of the EV 30 selling power.

[0027] [Home system configuration] Next, a system configuration on the home 10 side including the charging / discharging device 20 in this embodiment will be described. FIG. 2 is a block diagram showing an example of a system configuration on the home 10 side including the charging / discharging device 20. As shown in FIG.

[0028] 2, the charging / discharging device 20 includes a power adjustment unit 21 and a charging / discharging unit 22. The power adjustment unit 21 is a circuit unit that converts DC power generated by the solar panel 11 and charging power for the battery 31 and the stationary battery 13 into AC power, and controls the output power (power generation amount) of the solar panel 11. The power adjustment unit 21 includes a watt-hour meter for PV power (PV, stationary battery 13) and a watt-hour meter for commercial power. Each watt-hour meter outputs a signal corresponding to the amount of power (for example, a pulse signal) or data indicating the amount of power to a controller described later.

[0029] A power conditioner (PCS: Power Conditioning Subsystem) can be used for the power adjustment unit 21. There are two types of power conditioners: a power storage power conditioner that operates by connecting a battery to a power grid, and a PV power conditioner that operates by connecting a PV to a power grid. In this embodiment, the power adjustment unit 21 is configured as a hybrid type power conditioner having these two functions, but the power adjustment unit 21 may be configured as a separate unit for each function (distributed type). Also, the power adjustment unit 21 may be configured independent of the charging / discharging device 20.

[0030] The charging / discharging unit 22 charges the battery 31 of the EV 30 or the stationary battery 13 with the power output by the power adjustment unit 21. The charging / discharging unit 22 also discharges the power charged in the battery 31 or the stationary battery 13 and supplies it to the distribution board 12. The charging / discharging unit 22 charges (supplies) the battery 31 of the EV 30 with the power generated by the solar panel 11, the power stored in the stationary battery 13, or the commercial power 2 via the distribution board 12.

[0031] The charging / discharging device 20 is composed of a controller (processor, memory) that controls the operations of the power adjustment unit 21 and the charging / discharging unit 22, and a display unit such as a liquid crystal display panel. The controller is configured to be able to transmit and receive data to and from the power adjustment unit 21, the charging / discharging unit 22, and the display unit. The display unit displays the processing results of the controller, etc. Note that each of the power adjustment unit 21 and the charging / discharging unit 22 may be provided with a separate controller.

[0032] In the charging / discharging device 20, the controller acquires information about the source (solar panel 11, stationary battery 13, commercial power 2) of the electricity charged to the battery 31 of the EV 30 from the watt-hour meter of the power adjustment unit 21. Based on the information acquired from the watt-hour meter, the controller links information indicating the source (origin) of the electricity and information on the charge amount, which is the amount of electricity charged to the battery 31, with the charging date and time and transmits them to the information processing device 40. The information indicating the source of the electricity is information indicating the origin of the charging power of the battery 31, and may be referred to as the "electricity type" in the following explanation.

[0033] Generally, the solar panel 11 and the charging / discharging device 20 (particularly the power adjustment unit 21) are sold and installed separately, but they may also be sold as a set. A unique identification number is assigned to the charging / discharging device 20 (power adjustment unit 21). The charging / discharging device 20 of this embodiment can be considered a PCS in a broad sense that adds a charging function to a power conversion function.

[0034] The above-mentioned charging / discharging device 20 is a well-known device. The stationary battery 13 stores the power generated by the solar panel 11 when the EV 30 is not in the home 10. Therefore, when the battery 31 is charged with the stored power of the stationary battery 13, the power charged to the battery 31 is treated as if it were directly charged from the solar panel 11.

[0035] The solar power generation by the above-mentioned solar power generation panel 11 is one form of renewable energy utilization. In the power transfer system of the present embodiment, various types of renewable energy can be utilized, such as wind power, hydraulic power, and thermal energy (e.g., solar heat and geothermal energy, in addition to solar energy.

[0036] [System configuration for commercial facilities] Next, a system configuration on the commercial facility 60 side including the power selling device 70 in this embodiment will be described. FIG. 3 is a block diagram showing an example of a system configuration on the commercial facility 60 side including the power selling device 70. As shown in FIG.

[0037] 3, the commercial facility 60 includes an electricity selling device 70, a local terminal 80 connected to the electricity selling device 70, and a camera 90 that captures an image of the number printed on the license plate of the EV 30. The electricity selling device 70 is a power receiving device that receives power from a battery mounted on the vehicle, and may be one or more.

[0038] The power selling device 70 is a power receiving device that receives charging power (power to be sold) from the battery 31 of the EV 30. The power selling device 70 has a function of accepting an application for power sale when a user sells power stored in the battery 31 to the power selling device 70. The user displays on the mobile terminal 50 a two-dimensional code transmitted from the operation server 100 when charging the battery 31 at home 10. The power selling device 70 reads the two-dimensional code displayed on the mobile terminal 50 with the reading camera 71, and transmits the read two-dimensional code reading information to the local terminal 80.

[0039] The local terminal 80 is an example of a power supply availability determination device that determines whether or not to accept (purchase) an application for selling power using the battery 31 of the EV 30. The local terminal 80 receives an image of the license plate of the EV 30 captured by the camera 90 and two-dimensional code read information captured by the reading camera 71 of the power selling device 70. Upon receiving the two-dimensional code read information, the local terminal 80 requests the operation server 100 for the cumulative number of times the battery 31 of the EV 30 has been charged. Then, upon receiving the information on the cumulative number of times charging from the operation server 100, the local terminal 80 determines whether or not to sell the power, and displays the determination result on the display unit 72.

[0040] When the local terminal 80 determines to permit the power sale, the power selling device 70 receives charging power from the battery 31 of the EV 30. The power received by the power selling device 70 is supplied to ancillary equipment such as a stationary battery 61, air conditioning and heating equipment 62, elevators 63, and lighting equipment 64 in the commercial facility 60.

[0041] [EV control system configuration] Next, the configuration of the control system of the EV 30 in this embodiment will be described with reference to FIG. FIG. 4 is a block diagram showing an example of the configuration of a control system of the EV30.

[0042] The EV 30 includes a CPU (Central Processing Unit) 310, a main memory device 320, an input / output interface 330, an EV controller 340, and a battery 31. Each component is connected to each other so as to be able to communicate with each other via a system bus or the like. The CPU 310, the main memory device 320, and the input / output interface 330 are examples of hardware used as a computer. For example, the functions of the CPU 310, the main memory device 320, and the input / output interface 330 may be realized using an ECU (Electronic Control Unit).

[0043] The CPU 310 controls each part of the EV 30. Various software modules (programs), data, etc. are stored in the main memory 320. The CPU 310 reads out the program code of the software that realizes each function of the EV 30 according to this embodiment from an external memory device (not shown), loads it into the main memory device 320, and executes it. Note that other processors such as an MPU (Micro Processing Unit) may be used instead of the CPU.

[0044] The main storage device 320 stores a battery ID (Identification) 321 , a cumulative charge / discharge count 322 , a cumulative charge / discharge count update unit 323 , and an output processing unit 324 .

[0045] The battery ID 321 is identification information for uniquely identifying the battery 31. When the battery 31 can be identified by identifying the EV 30, information for identifying the EV 30 may be used instead of the battery ID 321.

[0046] The cumulative number of charges / discharges 322 is information related to the cumulative number of charges / discharges of the battery 31 corresponding to the battery ID 321. The cumulative number of charges / discharges is, for example, the cumulative number of charges and the cumulative number of discharges from the time the battery 31 or the EV 30 was manufactured to the present. The cumulative number of charges may be referred to as the “cumulative number of charges,” and the cumulative number of discharges may be referred to as the “cumulative number of discharges.” The battery ID 321 and the cumulative number of charges / discharges 322 are part of the operation data 32.

[0047] The cumulative charge / discharge count update unit 323 updates the cumulative charge count and the cumulative discharge count when it detects that the battery 31 has been charged or discharged. That is, the cumulative charge / discharge count update unit 323 increments the values ​​of the cumulative charge count and the cumulative discharge count by "1" when the battery 31 is charged or discharged. The location where charging and discharging are performed is arbitrary. Therefore, the cumulative charge count and the cumulative discharge count are updated both in the home 10 and in charging / discharging facilities other than the home 10.

[0048] The output processing unit 324 performs processing for outputting the target data from the input / output interface 330. In this embodiment, the output processing unit 324 processes the operation data 32, which includes the battery ID 321, the cumulative number of charging / discharging times 322, and the date and time when charging or discharging was performed, into a data format that can be output from the input / output interface 330.

[0049] The input / output interface 330 is an interface that performs data communication with the operation status management server 110 via wireless communication. For example, the input / output interface 330 transmits data such as the operation data 32 processed by the output processing unit 324 to the operation status management server 110. As an example, the input / output interface 330 can be configured using a TCU (Telematics Control Unit), which is a communication module connectable to a mobile communication network. Data input / output by the input / output interface 330 may be encrypted.

[0050] The EV controller 340 is a controller that controls the running of the EV 30. The EV controller 340 can be configured using an ECU, for example. The EV controller 340 operates using the charging power of the battery 31 or the power generated by an engine (not shown) as a power source. The EV controller 340 communicates with the CPU 310 via an in-vehicle network such as a Controller Area Network (CAN). The CPU 310 and the main memory device 320 may be provided inside the EV controller 340.

[0051] [Configuration of information processing device] Next, the configuration of the information processing device 40 in this embodiment will be described with reference to FIG. 5 is a block diagram showing an example of the configuration of the information processing device 40. As the information processing device 40, a general-purpose computer such as a personal computer can be used.

[0052] The information processing device 40 includes a CPU 410, a main memory device 420, an operation input unit 430, a display unit 440, and an input / output interface 450. Each unit is connected to each other so as to be able to communicate with each other via a system bus or the like. The functions of the CPU 410, the main memory device 420, and the input / output interface 450 as hardware are the same as the functions of the corresponding elements of the EV 30 shown in FIG. 4, and redundant explanations will be omitted as much as possible.

[0053] The main memory device 420 includes an electric power type receiving unit 421 , a charge amount receiving unit 422 , a customer information registration unit 423 , an input processing unit 424 , and an output processing unit 425 .

[0054] The power type reception unit 421 receives information on the power type according to the source (origin) of the power charged to the battery 31 of the EV 30 from the power adjustment unit 21 (power meter) of the charging / discharging device 20, and stores the information in association with the customer information. The power type is information indicating the origin of the power charged to the battery 31. The power type reception unit 421 can determine the power type based on which power meter the received information is from. Alternatively, the information sent from the power meter may include information for identifying the power type. For example, when the power charged to the battery 31 is derived from the power generated by the solar panel 11, the power type is "PV power". The same applies when the power of the stationary battery 13 is used to charge the battery 31. When the power charged to the battery 31 is derived from the commercial power 2, the power type is "commercial power".

[0055] The charge amount receiving unit 422 receives information on the charge amount, which is the amount of power charged in the battery 31 of the EV 30, from the power adjustment unit 21 (power meter) of the charge / discharge device 20, and stores the information in association with the customer information.

[0056] The customer information registration unit 423 performs a process of registering information for identifying a customer (hereinafter referred to as "customer information"). For example, a customer ID (an example of a customer identifier) ​​is used as the customer information. In this embodiment, the customer is assumed to be the user of the EV 30. The customer information registration unit 423 records the customer ID, the license plate number of the EV 30 used, an email address, the identification number of the power adjustment unit 21 (PCS), etc. in association with each other in a non-volatile memory (not shown).

[0057] The input processing unit 424 processes an input signal input from the operation input unit 430 in response to a user's operation on the operation input unit 430 .

[0058] The output processing unit 425 performs processing for outputting the target data from the input / output interface 450. In this embodiment, the output processing unit 425 processes the data including the customer information, the power type, and the charging amount into a data format that can be output from the input / output interface 450, and sends it to the input / output interface 450. In addition, the output processing unit 425 generates image data including information such as the customer information, the power type, and the charging amount, and outputs it to the display unit 440.

[0059] The operation input unit 430 is a device that generates an input signal in response to an input operation by a user and outputs the signal to the CPU 410 via a system bus. A mouse device, a keyboard, a touch sensor, or the like is used for the operation input unit 430, and the user can operate the operation input unit 430 to input information and instructions. The display unit 440 is a display device such as a liquid crystal display panel, etc. The display unit 440 displays a GUI screen, the contents processed by the output processing unit 425, etc.

[0060] The input / output interface 450 is an interface that performs data communication with the charging / discharging device 20 and the operation server 100. For example, the input / output interface 450 transmits data including customer information, power type, and charged amount processed by the output processing unit 425 to the operation server 100 via the network N. The input / output interface 450 can be configured using a communication device such as a network interface card (NIC), for example.

[0061] Data input and output by the input / output interface 450 may be encrypted. That is, data exchanged in the power transfer system 1 may be encrypted. In that case, each device is appropriately provided with an encryption processing unit and / or a decryption processing unit.

[0062] [Mobile device configuration] Next, the configuration of the mobile terminal 50 in this embodiment will be described with reference to FIG. 6 is a block diagram showing an example of the configuration of the mobile terminal 50. The mobile terminal 50 is a portable terminal such as a smartphone or a tablet terminal.

[0063] The mobile terminal 50 includes a CPU 510, a main memory device 520, an operation input unit 530, a display unit 540, and an input / output interface 450. The units are connected to each other so as to be able to communicate with each other via a system bus or the like. The functions of the CPU 510, the main memory device 520, the operation input unit 530, the display unit 540, and the input / output interface 550 as hardware are the same as the functions of the corresponding elements of the information processing device 40 shown in FIG. 5, and redundant explanations will be omitted as much as possible.

[0082] The power reception control circuit 750 is a controller that controls the reception of charging power for the battery 31 of the EV 30 when purchase is permitted.

[0083] [Operation server configuration] Next, the configuration of the operation server 100 in this embodiment will be described with reference to FIG. 8 is a block diagram showing an example of the configuration of the operation server 100. As the operation server 100, a general-purpose computer such as a personal computer can be used.

[0084] The operation server 100 includes a CPU 1010, a charging process main memory 1020, a power selling process main memory 1030, and an input / output interface 1040. Each unit is connected to each other so that they can communicate with each other via a system bus or the like. The operation server 100 includes a charging process main memory 1020 and a power selling process main memory 1030 as main memory devices. The charging process main memory 1020 and the power selling process main memory 1030 may be configured by dividing the address area using a single main memory device. The CPU 1010 realizes various functions by reading and executing programs stored in the charging process main memory 1020 and the power selling process main memory 1030.

[0085] The hardware functions of the CPU 1010, the charging processing main memory device 1020, the power selling processing main memory device 1030, and the input / output interface 1040 are the same as the functions of the corresponding elements of the information processing device 40 shown in FIG. 5, and duplicated explanations will be omitted as much as possible.

[0086] (Charging processing main memory device) The charging processing main memory device 1020 includes a customer / power source / charging amount reception unit 1021 , a customer ID / number plate management unit 1022 , a cumulative number of charging times during PV charging 1023 , a two-dimensional code issuing unit 1024 , and an output processing unit 1025 .

[0087] The customer / power type / charge amount receiving unit 1021 receives customer information, power type information, and the charge amount charged to the battery 31 of the EV 30 from the information processing device 40. For example, the customer / power type / charge amount receiving unit 1021 receives the charge amount of the battery 31 of the EV 30 from the information processing device 40 by customer (customer ID) and by power type.

[0088] The customer ID / number plate management unit 1022 manages the customer ID and the number plate of the EV 30 used by the customer. In addition, the customer ID and the number plate may be managed in association with contact information such as an email address of the customer's mobile terminal 50. Such information is registered by the customer using the information processing device 40 or the mobile terminal 50.

[0089] The cumulative number of charges during PV charging 1023 is the value of the cumulative number of charges during PV charging of the battery 31 acquired from the operation status management server 110 when the customer / power type / charging amount receiving unit 1021 receives PV as the power type from the information processing device 40. When the operation server 100 confirms that PV power has been charged to the battery 31 of the EV 30 in the home 10, it issues a two-dimensional code described below and acquires the latest cumulative number of charges of the battery 31 from the operation status management server 110. In addition, when the operation server 100 receives a request from the commercial facility 60 to sell the charging power of the battery 31, it acquires the latest cumulative number of charges of the battery 31 from the operation status management server 110.

[0090] When the customer / power type / charging amount receiving unit 1021 receives PV as the power type from the information processing device 40, the two-dimensional code issuing unit 1024 creates and issues a two-dimensional code to be transmitted to the user's mobile terminal 50. The license plate number of the EV 30 connected to the charging / discharging device 20 during PV charging is recorded in the two-dimensional code. Customer information (e.g., a customer ID) may also be recorded in the two-dimensional code.

[0091] The output processing unit 1025 performs processing for outputting the target data from the input / output interface 1040. For example, the output processing unit 1025 performs processing for notifying the mobile terminal 50 linked to the customer ID of the registered license plate number. The notification is performed, for example, by email, the electricity seller application 521, SNS, etc. The customer ID and contact information such as an email address are registered in advance in the operation server 100.

[0092] (Power sales processing main memory device) The electricity selling process main memory device 1030 includes a customer ID / number plate reception unit 1031 , a cumulative number of charging times when selling electricity 1032 , purchasing price information 1033 , and an output processing unit 1034 .

[0093] The license plate reception unit 1031 receives information on the license plate of the EV 30 photographed by the camera 90. The license plate reception unit 1031 also receives the customer ID and information on the license plate of the EV 30 that has been PV charged, which are included in the two-dimensional code read information from the local terminal 80. The information included in the two-dimensional code read information may be only the license plate information of the EV 30.

[0094] The cumulative number of charging times during power sale 1032 is the value of the cumulative number of charging times during power sale acquired from the operation status management server 110 in response to a request from the local terminal 80 when an application is made for power sale (power supply) using the battery 31 of the EV 30. The operation server 100 transfers this cumulative number of charging times during power sale to the local terminal 80.

[0095] The buy-back price information 1033 is information indicating the buy-back price when selling the charging power of the battery 31. For example, by associating the charging amount (kWh) with the buy-back price (yen), the buy-back amount (reward) for the charging amount sold from the battery 31 to the power selling device 70 is calculated. Instead of the buy-back amount, points that can be used for purchasing products or providing services may be used.

[0096] The output processing unit 1034 performs processing for outputting the target data from the input / output interface 1040. For example, the output processing unit 1034 outputs the purchase amount calculated from the charged amount and the purchase price to the power selling device 70 via the local terminal 80.

[0097] The input / output interface 1040 is an interface for performing data communication with the operational status management server 110 and the local terminal 80 .

[0098] [Local terminal configuration] Next, the configuration of the local terminal 80 in this embodiment will be described with reference to FIG. 9 is a block diagram showing an example of the configuration of the local terminal 80. As the local terminal 80, a general-purpose computer such as a personal computer can be used.

[0099] The local terminal 80 manages information on the commercial facility 60 side, and presents information managed for each facility in the operation server 100 and purchase availability information. The local terminal 80 includes a CPU 810, a main memory device 820, a display unit 830, and an input / output interface 840. Each unit is connected to each other so that they can communicate with each other via a system bus or the like. A general-purpose computer such as a personal computer can be used as the local terminal 80.

[0100] The functions of the CPU 810, the main memory device 820, the display unit 830, and the input / output interface 840 as hardware are the same as the functions of the corresponding elements of the information processing device 40 shown in FIG. 5, and duplicated explanations will be omitted as much as possible.

[0101] The main memory device 820 includes a customer information / number plate registration unit 821, a cumulative number of charging times during charging / electricity selling comparison unit 822, and an output processing unit 823.

[0102] The customer information / number plate registration unit 821 registers customer information and the number plate number of the EV 30 used by the customer. The customer information / number plate registration unit 821 has a function of recognizing the number plate number from the number of the number plate photographed by the camera 90 and the two-dimensional code read information. The customer information is, for example, the customer's name and customer ID. The customer information may also include the ownership type of the EV 30, i.e., whether it is owned by a corporation or an individual. However, it may be sufficient to only recognize and register the number plate information. In this embodiment, the customer information / number plate registration unit 821 compares the number plate number obtained from the image captured by the camera 90 with the number plate number obtained from the read information of the two-dimensional code. If the two match, the customer information / number plate registration unit 821 instructs the output processing unit 823 to obtain the cumulative number of charges of the battery 31 linked to the number plate from the operation server 100. However, the function of comparing the number plate numbers and the function of instructing the acquisition of the cumulative number of charges may be realized by a processing block separate from the customer information / number plate registration unit 821.

[0103] The cumulative number of charging times during charging / power selling comparison unit 822 compares the cumulative number of charging times of the battery 31 when the battery 31 is charged with electricity derived from renewable energy (PV power in this embodiment) with the cumulative number of charging times of the battery 31 when an application for selling (supplying) electricity from the battery 31 is made to the electricity selling device 70 that receives electricity supply from the battery 31. Then, the cumulative number of charging times during charging / power selling comparison unit 822 determines whether or not to permit the sale (supply) of electricity from the battery 31 to the electricity selling device 70 based on the comparison result. The cumulative number of charging times during charging / power selling comparison unit 822 displays the determination result on the display unit 830 and the display unit 72 of the electricity selling device 70 via the output processing unit 823.

[0104] The output processing unit 823 performs processing for outputting the target data from the input / output interface 840. The output processing unit 823 also performs processing for outputting to the display unit 830 a response to the application for selling the power of the battery 31, indicating whether or not the purchase is permitted.

[0105] The display unit 830 is a display device such as a liquid crystal display panel, and displays the contents managed for each facility by the operation server 100. For example, the display unit 830 displays customer information / number plate management contents 831, customer / amount of electricity sold / purchase price 832, and purchase eligibility determination result 833.

[0106] Customer information / number plate management contents 831 is a customer ID and a number plate number. The customer-specific / power selling amount / purchase price 832 is information indicating the power selling amount and purchase price for each customer. The purchase availability decision result 833 is information indicating the decision result as to whether or not the sale (purchase) of electric power is accepted for the license plate number of the EV 30 photographed by the camera 90 when the customer applies to sell electric power.

[0107] The input / output interface 840 is an interface that performs data communication with the camera 90, the power selling device 70, and the operation server 100. For example, the input / output interface 840 requests the operation server 100 for the cumulative number of times the battery 31 of the EV 30 that has applied to sell power has been charged, and receives the cumulative number of times the battery 31 has been charged during power sale from the operation server 100. The input / output interface 840 also transmits to the power selling device 70 the result of the decision as to whether or not to permit purchase of the power sale application.

[0108] The display unit 72 of the power selling device 70 displays information such as the result of the decision as to whether or not the purchase is permitted, and the purchase price according to the amount of charge if the purchase is permitted.

[0109] [Processing by power transfer system] Next, an overview of the processing performed by the power transfer system 1 in this embodiment will be described with reference to FIG. FIG. 10 is a flowchart showing an example of a procedure of processing by the power transfer system 1.

[0110] 10, a user of EV 30, who is a customer, connects battery 31 of EV 30 to a charging / discharging device 20 installed in home 10, and charges battery 31 of EV 30 with the charging / discharging device 20 (S1). At this time, the charging / discharging device 20 transmits to information processing device 40 the type of power charged in battery 31, the amount of charge, and the charging date and time.

[0111] Next, in the EV 30, the accumulated charge / discharge count update unit 323 updates the accumulated charge count. Then, the CPU 310 transmits the operation data (including the accumulated charge / discharge count during charging) to the operation status management server 110 by wireless communication (S2).

[0112] Next, the information processing device 40 transmits charge / discharge data (for example, type of power, amount of charge, and charge date and time) to the operation server 100 (S3).

[0113] Next, the operation server 100 transmits a two-dimensional code including the license plate number of the EV 30 to the mobile terminal 50 of the user of the EV 30 (S4). After that, the user drives the EV 30 to a commercial facility 70 and stops the EV 30 in front of the power selling device 70 to sell the charging power of the EV 30.

[0114] Next, the user (driver) of the EV 30 applies to the power selling device 70 for selling power using the charging power of the battery 31. The EV 30 connected to the power selling device 70 transmits a part of the operation data (the cumulative number of times charging occurred during power selling) to the operation status management server 110 (S5).

[0115] Next, the user displays the two-dimensional code transmitted from the operation server 100 to the mobile terminal 50 on a screen and holds it in front of the camera 71 of the power selling device 70. The power selling device 70 performs a reading process of the two-dimensional code photographed by the camera 71, and transmits the read information of the two-dimensional code to the local terminal 80 (S6). The read information of the two-dimensional code includes at least the license plate number of the EV 30. In addition, the local terminal 80 acquires the information of the license plate photographed by the camera 90.

[0116] Next, the local terminal 80 requests the operation server 100 to transmit the cumulative number of times the battery 31 linked to the license plate information. Then, the operation server 100 acquires the cumulative number of times the EV 30 linked to the license plate information has been charged and discharged during charging and power selling from the operation status management server 110. Then, the operation server 100 transmits various information including the cumulative number of times the battery 31 has been charged and discharged during charging and power selling to the local terminal 80 (S7).

[0117] Next, the local terminal 80 determines whether the various information acquired from the operation server 100 satisfies the conditions for accepting the power sale, and transmits the determination result to the power selling device 70 (S8). If the conditions for accepting the power sale are satisfied (YES determination in S8), the local terminal 80 permits acceptance of the power sale, that is, determines that the purchase is permitted (S9). Upon receiving the purchase permission, the power selling device 70 receives the PV-derived power that has been charged in the battery 31 (S10).

[0118] On the other hand, if the conditions for accepting the power sale are not met (NO in S8), the local terminal 80 does not permit the acceptance of the power sale, that is, determines that the purchase is not permitted (S11), and ends the process. After the process of step S10 or S11 is completed, this process ends.

[0119] [Processing by information processing device] Next, the process performed by the information processing device 40 in this embodiment will be described with reference to FIG. FIG. 11 is a flowchart showing an example of a procedure of processing by the information processing device 40.

[0120] In FIG. 11, a user of EV 30, who is a customer, connects battery 31 of EV 30 to charge / discharge device 20 installed in home 10, and charging of battery 31 of EV 30 is started by charge / discharge device 20 (S21).

[0121] The charging / discharging device 20 detects that the power supply to the battery 31 has been completed, that the battery 31 is in a fully charged state, or that the charger has been removed (the connection between the charging / discharging device 20 and the battery 31 is released) (S22).

[0122] Next, the power type receiving unit 421 and the charge amount receiving unit 422 of the information processing device 40 receive the power type, charge amount, and charge date and time of the power charged to the battery 31 from the charge / discharge device 20 as charge / discharge data (S23).

[0123] Next, the output processing unit 425 of the information processing device 40 transmits to the operation server 100 the customer ID of the user (customer) of the EV 30 that has been registered in advance, the type of electricity (electricity origin) received from the charging / discharging device 20, and information on the amount of charge (S24).

[0124] Next, in operation server 100, when customer-specific / power-type / charge-amount receiving unit 1021 receives the charge / discharge data from information processing device 40 in step S24, two-dimensional code issuing unit 1024 issues a two-dimensional code (S25). At least the license plate number of EV 30 connected to charging / discharging device 20 during PV charging is recorded in the two-dimensional code.

[0125] Next, the output processing unit of the operation server 100 transmits the two-dimensional code to the mobile terminal 50 of the user of the EV 30 by email or the like (S26). After the process of step S26 is completed, this process ends.

[0126] [Purchase processing by commercial facilities] Next, the purchase process by the commercial facility 60 in this embodiment will be described with reference to FIG. FIG. 12 is a flowchart showing an example of a procedure for a purchasing process by the commercial facility 60.

[0127] 12, the license plate number of EV 30 equipped with battery 31 that sells power at commercial facility 60 is photographed by camera 90 installed near power selling device 70 (S31). Customer information / license plate registration unit 821 of local terminal 80 recognizes the license plate number from the image captured by camera 90.

[0128] Next, the two-dimensional code displayed on the mobile terminal 50 of the user of the EV 30 is photographed by the camera 71 of the power selling device 70. In the power selling device 70, the two-dimensional code reading unit 722 of the power selling application 721 reads the two-dimensional code photographed by the camera 71 (S32). The read information of the two-dimensional code that has been read is input to the local terminal 80.

[0129] Next, the customer information / license plate registration unit 821 of the local terminal 80 compares the license plate number photographed by the camera 90 with the license plate number obtained from the read information of the two-dimensional code. If the two license plate numbers match, the output processing unit 823 of the local terminal 80 transmits the read information of the two-dimensional code, i.e., the license plate number, to the operation server 100 (S33). At this time, the local terminal 80 transmits the license plate number and requests various types of information related to charging linked to the license plate number (S34).

[0130] Next, the local terminal 80 acquires various information including the cumulative number of times the battery 31 is charged and the cumulative number of times the battery is charged when the power is sold from the operation server 100 (S35). The various information includes, for example, the customer ID, the type of power (power origin), and the amount of charge.

[0131] Next, the cumulative number of charging times during charging / power selling comparison unit 822 of the local terminal 80 confirms that the power of the battery 31 applied for power sale is PV power, and compares the cumulative number of charging times during charging with the cumulative number of charging times during power sale to determine whether or not to accept the power sale (S36).

[0132] The cumulative number of charges during charging / power selling comparison unit 822 of the local terminal 80 determines whether or not power selling is acceptable based on the result of the process in step S36 (S37). If the conditions of the power type and cumulative number of charges in step S36 are met and power selling is acceptable (YES in S37), the cumulative number of charges during charging / power selling comparison unit 822 displays the judgment result that power selling is acceptable on the display unit 72 of the power selling device 70 and notifies the power selling device 70 that "power selling is acceptable." Then, the power selling device 70 starts supplying (receiving) power up to the available amount of power supply (S38).

[0133] Then, the power selling device 70 performs the power supply process until the power supply is completed (S39). For example, the power selling device 70 charges the power by PV charging with the charge amount registered in the operation server 100 set to the maximum value. When the power supply is completed, this process ends.

[0134] Furthermore, if the power sale is not acceptable (NO in S37), the cumulative number of charges during charging / power selling comparison unit 822 displays the judgment result that the power sale cannot be accepted on the display unit 72 of the power selling device 70, notifies the power selling device 70 of "power sale cannot be accepted" and stops the transaction. The cumulative number of charges during charging / power selling comparison unit 822 determines that the power sale is not acceptable if the power type is not PV power or if the cumulative number of charges during charging and power selling do not match.

[0135] Furthermore, if the power type includes PV power and the cumulative number of times of charging and selling power do not match (other in S37), the cumulative number of times of charging and selling power comparison unit 822 treats all of the power, including the PV power, as general commercial power (S41) and proceeds to step S38. In this case, the specified charge amount is supplied for the power in the battery 31, not limited to the PV power.

[0136] As described above, the power transfer system (power transfer system 1) of this embodiment is a power transfer system that transfers power using a storage battery (battery 31) mounted on a mobile object (EV30), and is equipped with a power supply permission determination device (local terminal 80) that compares the cumulative number of times the storage battery is charged when the storage battery is charged with electricity derived from renewable energy (e.g., PV power) with the cumulative number of times the storage battery is charged when an application for power supply from the storage battery is made to a power receiving device (power selling device 70) that receives power from the storage battery, and determines whether or not to permit power supply from the storage battery to the power receiving device based on the comparison result.

[0137] With the above configuration, even if the seller charges the battery of the mobile body at a charging facility other than the seller's home, the buyer can identify the origin of the electricity charged in the battery of the mobile body of the seller (the type of energy used for generating electricity).
