A power transmission and reception system (1) that transmits and receives power by means of a battery mounted on a mobile body (30) is provided with a power supply permission / non-permission determination device (local terminal (80)). The power supply possibility determination device compares the cumulative number of charges of the storage battery when the storage battery is charged by the power from the renewable energy source with the cumulative number of charges of the storage battery when the power reception device (70) receiving the power supply from the storage battery applies for the power supply by the storage battery. Based on the comparison result, it is determined whether or not power supply from the battery to the power receiving device is permitted.

Description

Technical Field

[0001] The present invention relates to a power transfer system and a power transfer method for exchanging power (electric energy) charged in a battery of a mobile object. Background Art

[0002] In recent years, the number of households that have installed solar power generation equipment (hereinafter referred to as "PV") in their homes has increased in order to take advantage of the fixed purchase system for renewable energy (hereinafter referred to as the "FIT (Feed-in Tariff) system") and the like. However, with the popularization of PV, the purchase price of renewable energy has been decreasing year by year, and due to the recent rise in the unit price of commercial electricity, an increase in households have stopped using the FIT system and are consuming PV-generated electricity (hereinafter referred to as "PV electricity") at home. In addition, there are many households that discard PV electricity before it is fully used. On the other hand, in the global trend towards carbon neutrality, the number of companies that purchase expensive electricity from renewable energy with the purpose of contributing to environmental measures is also increasing.

[0003] Patent Document 1 proposes a power system that uses a storage battery mounted on a mobile body to sell electricity based on renewable energy. Patent Document 1 states that "the control unit determines the upper limit of the power based on the first parameter included in the charge and discharge history information" and "is a parameter equivalent to the power from renewable energy in the remaining capacity of the storage battery" of the power storage device mounted on the mobile body. In addition, Patent Document 1 states that "the control unit may also permit the power storage device to sell power when the second parameter included in the charge and discharge history information is 0". The second parameter is a parameter corresponding to the power from the exhaustible energy.

[0004] Patent Document 1: Japanese Patent No. 7136785 Summary of the invention

[0005] In the power system described in Patent Document 1, when a mobile power storage device (battery) 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 is stored in the power storage device.

[0006] However, usually, charging devices installed on the street do not identify whether the power charged to the battery of the mobile object is from renewable energy. Therefore, even if the charging device (EV charging and discharging equipment) at home identifies that the power of the battery is from renewable energy, if the battery of the mobile object is charged by the charging equipment on the street, it cannot be determined whether the power charged to the battery is from renewable energy.

[0007] For example, imagine the following situation: the seller charges the battery of a mobile object with PV power using a charging device (EV charging and discharging equipment) installed at home, etc. that can identify the source of the charging power, and then sells the power charged to the battery to the buyer. If the PV power of the battery is exhausted before the seller sells the power, and the battery is charged using a charging device other than the seller's home, the buyer cannot know the source of the power used to charge the battery.

[0008] In view of the above situation, a method is desired in which the buyer can identify the source of power (type of energy used for power generation) used to charge the battery of the seller's mobile object even when the seller charges the battery of the mobile object using a charging facility other than the seller's home.

[0009] In order to solve the above-mentioned problems, one embodiment of the present invention is a power transfer system that uses a battery mounted on a mobile body to transfer power, and the power transfer system includes: a power supply availability determination device that compares the cumulative number of times the battery is charged when the battery is charged with power from renewable energy and the cumulative number of times the battery is charged when a power receiving device that receives power from the battery is requested to be powered by the battery, and determines whether to permit power supply from the battery to the power receiving device based on the comparison result.

[0010] According to at least one aspect of the present invention, even when the seller charges the battery of the mobile object at a charging facility other than the seller's home, the buyer can identify the source of the power used to charge the battery of the seller's mobile object (the type of energy used for power generation).

[0011] The other problems, structures, and effects than those described above will become clear from the following description of the embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In addition, for example, various names such as "XX information", "XX table", "XX list", and "XX overview" are interchangeable. In addition, when describing identification information, "identification information", "name", "ID", etc. are used, but they are interchangeable.

[0027] <One embodiment of the present invention>

[0028] Reference Figures 1 to 12A power transfer system using a battery (storage battery) mounted on a mobile body according to one embodiment of the present invention is described. The power transfer system of this embodiment is a system that charges power to a battery mounted on a mobile body and sells the power to a user. The mobile body is, for example, an electric vehicle (EV) or other vehicle. Electric vehicles also include plug-in hybrid vehicles and other vehicles that are equipped with a relatively large capacity battery and can supply power to the outside.

[0029] [Overall structure of the power transfer system]

[0030] First, refer to Figure 1 The overall configuration of a power transfer system according to an embodiment of the present invention will be described.

[0031] Figure 1 It is a schematic diagram showing an example of the overall configuration of the power transfer system according to the present embodiment.

[0032] The power transfer system 1 includes a solar panel 11 (solar power generation device (PV)) installed in a home 10 or the like, and a charging and discharging device 20 for charging and discharging a battery using the 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 Figure 2 ).

[0033] A distribution board 12 is installed in the home 10. The distribution board 12 is connected to a distribution line supported by a pole and a charging and discharging device 20. The distribution board 12 distributes commercial power 2 or power supplied from the charging and discharging device 20 to household devices (electrical devices, sockets) and the like.

[0034] The charging and discharging device 20 has the function of charging the battery 31 of the EV 30 and the function of extracting power from the battery 31. The battery 31 is a storage battery used for the transfer of power (selling power). The power stored in the battery 31 is recorded as "EV power". The EV 30 records the history of the charge and discharge of the battery 31 as the operation data 32. Then, the EV 30 sends the operation data 32 to the operation status management server 110 via OTA (Over The Air, air download technology).

[0035] The operating status management server 110 is a server managed and operated by, for example, an automobile manufacturing company. The operating status management server 110 manages the operating status (driving and charging and discharging information) of the vehicle by receiving and recording the operating data 32 transmitted from the vehicle such as the EV 30 manufactured by the company.

[0036] The operation data 32 includes at least information on the charge and discharge of the battery 31. The information on the charge and discharge of the battery 31 is, for example, the cumulative number of charges and the cumulative number of discharges of the battery 31 since the manufacture of the EV 30. The cumulative number of charges and the cumulative number of discharges are associated with the identification information of the battery 31 (or the EV 30) and managed. The operation data 32 also includes information related to the driving of the EV 30.

[0037] The information processing device 40 is connected to the charging and discharging device 20. For example, the information processing device 40 is installed in the home 10. The information processing device 40 transmits information (charging and discharging data) related to the charging and discharging of the battery 31 by the charging and discharging device 20 to the operation server 100 via a network N such as the Internet. In addition, the charging and discharging device 20 may output information related to the charging and discharging of the fixed battery 13 in addition to the battery 31 to the information processing device 40.

[0038] The operation server 100 is a server for managing the operation of the entire power transfer system 1 using the battery 31 of the EV 30. When the operation server 100 receives information related to the charge and discharge of the battery 31 from the charge and discharge device 20, it issues a two-dimensional code based on the information related to the charge and discharge and sends it to the portable terminal 50 of the user or owner of the EV 30. The two-dimensional code can be sent using a communication application such as an e-mail or SNS (Social Network Service).

[0039] When selling the charging power of the battery 31 of the EV 30, the two-dimensional code is used for the purpose of authenticating the legitimate user or owner of the EV 30. In the two-dimensional code, at least the license plate information of the EV 30 is recorded, wherein the EV 30 is equipped with the battery 31 that has been charged with power from PV in the home 10. The license plate information refers to a number added to identify the vehicle, such as a car registration number mark.

[0040] The operation server 100 has data of the registrant and contact information that has been pre-established with the vehicle license plate information, and sends a QR code to the registrant's contact information after charging. Here, the registrant is the user or owner of the EV30, and the contact information is the email address or SNS account of the portable terminal 50. In the following, an example of a user selling the charging power of the battery 31 is described, but the same is true for the owner.

[0041] The operation server 100 receives information related to 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 receiving a request to transmit the cumulative number of times of charging of the battery 31 mounted on the EV 30 from the local terminal 80 , the operation server 100 transmits the cumulative number of times of charging to the local terminal 80 .

[0042] In addition, the power transfer system 1 includes a power selling device 70 for selling EV power installed in a commercial facility 60, and a local terminal 80 for transmitting and receiving data with the power selling device 70. The commercial facility 60 is an example of a buyer (user) of power charged to the battery 31 of the EV 30. The local terminal 80 is connected to a camera 90 for photographing the license plate of the EV 30 that sells power.

[0043] [System structure on the home side]

[0044] Next, a system configuration of the household 10 including the charging and discharging device 20 according to the present embodiment will be described.

[0045] Figure 2 1 is a block diagram showing an example of a system configuration on the household 10 side including the charging and discharging device 20 .

[0046] like Figure 2 As shown, the charging and discharging device 20 includes a power adjustment unit 21 and a charging and discharging unit 22. The power adjustment unit 21 is a circuit unit that converts the DC power generated by the solar panel 11, the battery 31, and the charging power of the fixed battery 13 into AC power, or controls the output power (power generation) of the solar panel 11. The power adjustment unit 21 includes a power meter for PV power (PV, fixed battery 13) and a power meter for commercial power. Each power meter outputs a signal (for example, a pulse signal) corresponding to the power or data indicating the power to a controller described later.

[0047] The power adjustment unit 21 can use a power conditioner (PCS: Power Conditioning Subsystem). Among the power conditioners, there are storage power conditioners that interconnect the battery and the power system and operate, and PV power conditioners that interconnect the PV and the power system and operate. In this embodiment, the power adjustment unit 21 is configured as a hybrid power conditioner having these two functions, but it can also be configured as an independent structure (distributed type) for each function. In addition, the power adjustment unit 21 can also be configured independently from the charging and discharging device 20.

[0048] The charging and discharging unit 22 charges the battery 31 of the EV 30 or the fixed battery 13 with the power output by the power adjustment unit 21. In addition, the charging and discharging unit 22 discharges the power charged in the battery 31 or the fixed battery 13 and supplies it to the distribution board 12. The charging and discharging unit 22 charges (supplies power to) the battery 31 of the EV 30 with the power generated by the solar panel 11, the power stored in the fixed battery 13, or the commercial power 2 via the distribution board 12.

[0049] The charging and discharging device 20 is composed of a controller (processor, memory) that controls the operation of the power adjustment unit 21 and the charging and discharging unit 22, and a display unit such as a liquid crystal display panel. The controller is configured to be able to send and receive data with the power adjustment unit 21, the charging and discharging unit 22, and the display unit. The processing results of the controller are displayed on the display unit. In addition, the power adjustment unit 21 and the charging and discharging unit 22 can also be equipped with controllers separately.

[0050] In the charging and discharging device 20, the controller obtains information about the source of power (solar panel 11, fixed battery 13, commercial power 2) charged to the battery 31 of the EV 30 from the power meter of the power adjustment unit 21. Based on the information obtained from the power meter, the controller associates the information indicating the source of power generation (origin) and the information about the amount of power charged to the battery 31, i.e., the charge amount, with the charging date and time and sends them to the information processing device 40. The information indicating the source of power generation is information indicating the source of the charging power of the battery 31, and is sometimes referred to as "power category" in the following description.

[0051] Usually, the solar panel 11 and the charging and discharging device 20 (especially, the power adjustment unit 21) are sold and installed separately, but sometimes they are sold as a set. A unique identification number is assigned to the charging and discharging device 20 (power adjustment unit 21). The charging and discharging device 20 of this embodiment can be said to be a generalized PCS that adds a charging function to the power conversion function.

[0052] The above-mentioned charging and discharging device 20 is a well-known device. In addition, when EV30 is not in the home 10, the fixed battery 13 stores the power generated by the solar panel 11. Therefore, when the stored power of the fixed battery 13 is charged to the battery 31, the power charged to the battery 31 is processed in the same way as the power directly charged from the solar panel 11.

[0053] The solar power generation by the solar panel 11 is a form of renewable energy utilization. In the power transfer system of this embodiment, not only solar energy but also various renewable energy sources such as wind power, water power, and thermal energy (for example, solar energy and geothermal energy) can be utilized.

[0054] [System structure on the commercial facility side]

[0055] Next, a system configuration of commercial facility 60 including power vending device 70 in the present embodiment will be described.

[0056] Figure 3 1 is a block diagram showing an example of a system configuration on the commercial facility 60 side including the power vending device 70 .

[0057] like Figure 3As shown, commercial facility 60 includes power vending device 70, local terminal 80 connected to power vending device 70, and camera 90 for photographing the number written on the license plate of EV 30. Power vending device 70 is a power receiving device that receives power from a battery mounted on a vehicle, and may be one or more.

[0058] The power selling device 70 is a power receiving device that receives charging power (power selling power) from the battery 31 of the EV 30. The power selling device 70 has a function of accepting a power selling application when the user sells the power stored in the battery 31 to the power selling device 70. When the user charges the battery 31 at home 10, the two-dimensional code sent from the operation server 100 is displayed on the portable terminal 50. The power selling device 70 reads the two-dimensional code displayed on the portable terminal 50 through the camera 71, and sends the read information of the read two-dimensional code to the local terminal 80.

[0059] The local terminal 80 is an example of a power supply availability determination device that determines whether power supply is accepted (whether it can be purchased) for a power sales application using the battery 31 of the EV 30. The local terminal 80 receives the image of the license plate of the EV 30 captured by the camera 90 and the two-dimensional code reading information captured by the camera 71 of the power sales device 70. When the local terminal 80 receives the two-dimensional code reading information, it requests the operation server 100 for the cumulative number of times the battery 31 of the EV 30 is charged. Then, when the local terminal 80 receives the information of the cumulative number of times of charging from the operation server 100, it determines whether the power can be sold, and displays the determination result on the display unit 72.

[0060] When local terminal 80 determines that power selling is permitted, power selling device 70 receives charging power from battery 31 of EV 30. Power sold by power selling device 70 is supplied to auxiliary equipment such as fixed battery 61, cooling and heating equipment 62, elevator 63, and lighting equipment 64 of commercial facility 60.

[0061] [Configuration of EV control system]

[0062] Next, refer to Figure 4 The configuration of the control system of EV30 in this embodiment will be described.

[0063] Figure 4 This is a block diagram showing a configuration example of a control system of EV30.

[0064] EV30 includes a CPU (Central Processing Unit) 310, a main storage device 320, an input / output interface 330, an EV controller 340, and a battery 31. Each unit is connected to each other through a system bus or the like so as to be able to communicate with each other. CPU310, main storage device 320, and input / output interface 330 are examples of hardware used as a computer. For example, an ECU (Electronic Control Unit) may be used to implement the functions of CPU310, main storage device 320, and input / output interface 330.

[0065] CPU 310 controls each part of EV 30. Various software modules (programs), data, etc. are stored in main storage device 320. CPU 310 reads the program code of the software that implements each function of EV 30 of this embodiment from an external storage device (not shown), loads it into main storage device 320, and executes it. In addition, other processors such as MPU (MicroProcessing Unit) may be used instead of CPU.

[0066] The main storage device 320 stores a battery ID (Identification) 321 , a cumulative charge and discharge count 322 , a cumulative charge and discharge count update unit 323 , and an output processing unit 324 .

[0067] 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.

[0068] The cumulative charge and discharge times 322 is information related to the cumulative charge and discharge times of the battery 31 that matches the battery ID 321. As an example, the cumulative charge and discharge times are the cumulative value of the charge times and the cumulative value of the discharge times from the manufacture of the battery 31 or EV 30 to the present. The cumulative value of the charge times is sometimes referred to as the "cumulative charge times", and the cumulative value of the discharge times is sometimes referred to as the "cumulative discharge times". The battery ID 321 and the cumulative charge and discharge times 322 are part of the operation data 32.

[0069] The cumulative charge and discharge times update unit 323 updates the cumulative charge times and the cumulative discharge times when the charging and discharging of the battery 31 is detected. That is, the cumulative charge and discharge times update unit 323 increases the value of the cumulative charge times and the cumulative discharge times by "1" when the battery 31 is charged or discharged. The place where charging and discharging are performed is arbitrary. Therefore, the cumulative charge times and the cumulative discharge times are updated in the home 10 and any charging and discharging facilities outside the home 10.

[0070] 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 including the battery ID 321, the cumulative charge / discharge count 322, and the date and time of charging or discharging into a data format that can be output from the input / output interface 330.

[0071] The input / output interface 330 is an interface for data communication with the operation status management server 110 through wireless communication. For example, the input / output interface 330 sends 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 communication module that can be connected to a mobile communication network, that is, a TCU (Telematics Control Unit). Data input and output by the input / output interface 330 can also be encrypted.

[0072] The EV controller 340 is a controller for controlling the driving of the EV 30. As an example, the EV controller 340 can be configured using an ECU. The EV controller 340 operates using the charging power of the battery 31 or the generated power of the engine (not shown) as a power source. The EV controller 340 communicates with the CPU 310 via the vehicle network of the CAN (Controller Area Network). In addition, the CPU 310 and the main storage device 320 can also be set inside the EV controller 340.

[0073] [Structure of information processing device]

[0074] Next, refer to Figure 5 The configuration of the information processing device 40 in this embodiment will be described.

[0075] Figure 5 2 is a block diagram showing a configuration example of the information processing device 40. As the information processing device 40, a general-purpose computer such as a personal computer can be used.

[0076] The information processing device 40 includes a CPU 410, a main storage device 420, an operation input unit 430, a display unit 440, and an input / output interface 450. Each unit is connected to each other via a system bus or the like so as to be able to communicate with each other. The functions of the CPU 410, the main storage device 420, and the input / output interface 450 as hardware are similar to those of the CPU 410. Figure 4 The functions of the corresponding elements of the EV30 shown are the same, and duplicate descriptions are omitted as much as possible.

[0077] The main storage device 420 includes a 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 .

[0078] The power category receiving unit 421 receives information on the power category corresponding to the source (origin) of the power of the battery 31 charged to the EV 30 from the power adjustment unit 21 (electricity meter) of the charging and discharging device 20, and stores it in association with the customer information. The power category is information indicating the source of the charging power of the battery 31. The power category receiving unit 421 can determine the power category based on which electricity meter the received information comes from. Alternatively, information identifying the power category may be included in the information sent from the electricity meter. For example, in a case where the power charged to the battery 31 comes from the power generated by the solar panel 11, the power category is "PV power". The same is true for a case where the power of the fixed battery 13 is used to charge the battery 31. In addition, in a case where the power charged to the battery 31 comes from commercial power 2, the power category is "commercial power".

[0079] Charge amount receiving unit 422 receives information on the charge amount, which is the amount of electricity charged to battery 31 of EV 30 , from power adjustment unit 21 (electricity meter) of charging and discharging device 20 , and stores the information in association with customer information.

[0080] 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 EV30. The customer information registration unit 423 records the customer ID, the license plate number of the EV30 used, the email address, and the identification number of the power adjustment unit 21 (PCS) in a non-volatile memory (not shown) in correspondence with each other.

[0081] The input processing unit 424 processes an input signal input from the operation input unit 430 according to the user's operation on the operation input unit 430 .

[0082] The output processing unit 425 performs processing for outputting the target data from the input / output interface 450. In the present embodiment, the output processing unit 425 processes the data including the customer information, the power type, and the charge amount into a data format that can be output from the input / output interface 450, and transmits the data 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 charge amount, and outputs the image data to the display unit 440.

[0083] The operation input unit 430 generates an input signal according to the user's input operation and outputs it to the CPU 410 via the system bus. The operation input unit 430 uses a mouse device, a keyboard, a touch sensor, etc. The user can operate the operation input unit 430 to input information and instructions.

[0084] The display unit 440 is a display device such as a liquid crystal display panel, etc. The display unit 440 displays a GUI screen, content processed by the output processing unit 425, and the like.

[0085] The input / output interface 450 is an interface for data communication with the charging / discharging device 20 and the operation server 100. For example, the input / output interface 450 sends data including customer information, power type, and charge amount processed by the output processing unit 425 to the operation server 100 via the network N. As an example, the input / output interface 450 can be configured using a communication device such as a NIC (Network Interface Card).

[0086] The data input and output by the input / output interface 450 may be encrypted. That is, the data exchanged by the power transfer system 1 may be encrypted. In this case, each device appropriately includes an encryption processing unit and / or a decryption processing unit.

[0087] [Structure of portable terminal]

[0088] Next, refer to Figure 6 The configuration of the portable terminal 50 in this embodiment will be described.

[0089] Figure 6 2 is a block diagram showing a configuration example of the portable terminal 50. The portable terminal 50 is a portable terminal such as a smartphone or a tablet terminal.

[0090] The portable terminal 50 includes a CPU 510, a main storage device 520, an operation input unit 530, a display unit 540, and an input / output interface 550. Each unit is connected to each other via a system bus or the like so as to be able to communicate with each other. The functions of the CPU 510, the main storage device 520, the operation input unit 530, the display unit 540, and the input / output interface 550 as hardware are similar to those of the CPU 510. Figure 5 The functions of corresponding elements of the information processing device 40 shown are the same, and duplicate descriptions are omitted as much as possible.

[0104] The main storage device 720 includes a power vending application 721 , a two-dimensional code reading unit 722 , an input processing unit 723 , and an output processing unit 724 .

[0105] Power selling application 721 is an application that runs in power selling device 70 when a user sells power stored in battery 31 of EV 30 to power selling device 70 .

[0106] The two-dimensional code reading unit 722 is one of the functions of the power selling application 721. The two-dimensional code reading unit 722 reads the content of the two-dimensional code from the image of the two-dimensional code captured by the two-dimensional code reading camera 71. The result of reading the two-dimensional code is referred to as "two-dimensional code reading information".

[0107] The input processing unit 723 processes an input signal input from the operation input unit 730 according to the operation of the operation input unit 730 by the user.

[0108] The output processing unit 724 performs processing for outputting the object data from the input / output interface 750. In the present embodiment, the output processing unit 724 processes the two-dimensional code reading information sent from the two-dimensional code reading unit 722 into a predetermined data format and sends it to the input / output interface 450. In the case where there are multiple power selling devices 70, the two-dimensional code reading information is sent together with information identifying the power selling device 70 that has accepted the power selling application. In addition, the output processing unit 724 outputs the answer of purchase permission / non-permission for the power selling application of the battery 31 sent from the local terminal 80 to the display unit 72.

[0109] The operation input unit 730 is a device that generates an input signal according to an input operation of the user and outputs the input signal to the CPU 710 via the system bus.

[0113] Power reception control circuit 750 is a controller that controls the reception of charging power of battery 31 of EV 30 when the purchase is permitted.

[0114] [Structure of operation server]

[0115] Next, refer to Figure 8 The configuration of the operation server 100 in this embodiment will be described.

[0116] Figure 82 is a block diagram showing a configuration example of the operation server 100. As the operation server 100, a general-purpose computer such as a personal computer can be used.

[0117] The operation server 100 includes a CPU 1010, a charging processing main storage device 1020, a power selling processing main storage device 1030, and an input / output interface 1040. Each unit is connected to each other through a system bus or the like so as to be able to communicate with each other. The operation server 100 includes a charging processing main storage device 1020 and a power selling processing main storage device 1030 as main storage devices. The charging processing main storage device 1020 and the power selling processing main storage device 1030 can also be configured by dividing address areas using one main storage device. The CPU 1010 realizes various functions by reading and executing programs stored in the charging processing main storage device 1020 and the power selling processing main storage device 1030.

[0118] The functions of the CPU 1010, the charging processing main storage device 1020, the power selling processing main storage device 1030, and the input / output interface 1040 as hardware are similar to Figure 5 The functions of corresponding elements of the information processing device 40 shown are the same, and duplicate descriptions are omitted as much as possible.

[0119] (Charge Processing Main Storage Device)

[0120] The charging processing main storage device 1020 includes a customer / power source / charge amount receiving unit 1021 , a customer ID / license plate management unit 1022 , a cumulative number of charging times during PV charging 1023 , a QR code issuing unit 1024 , and an output processing unit 1025 .

[0121] The customer / power source / charged amount receiving unit 1021 receives customer information, power category information, and the amount of charge charged to the battery 31 of the EV 30 from the information processing device 40. For example, the customer / power source / charged amount receiving unit 1021 receives the amount of charge of the battery 31 of the EV 30 from the information processing device 40 for each customer (customer ID) and each power category.

[0122] The customer ID / license plate management unit 1022 manages the customer ID and the license plate number of the EV30 used by the customer. In addition, the customer ID and the license plate number may be associated with the contact information such as the email address of the customer's portable terminal 50 for management. The customer registers this information using the information processing device 40 or the portable terminal 50.

[0123] The cumulative number of times of charging during PV charging 1023 is a value of the cumulative number of times of charging during PV charging of the battery 31 obtained from the operating status management server 110 when the customer / power source / charged amount receiving unit 1021 receives PV as the power type from the information processing device 40. When it is confirmed that the battery 31 of the EV 30 is charged with PV power in the home 10, the operation server 100 issues a QR code described later and obtains the latest cumulative number of times of charging the battery 31 from the operating status management server 110. In addition, when a request to sell charging power for the battery 31 in the commercial facility 60 is received, the operation server 100 obtains the latest cumulative number of times of charging the battery 31 from the operating status management server 110.

[0124] When the customer / power source / charge 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 sent to the user's portable terminal 50. The license plate number of the EV 30 connected to the charging and discharging device 20 during PV charging is recorded in the two-dimensional code. Customer information (for example, customer ID) may also be recorded in the two-dimensional code.

[0125] The output processing unit 1025 performs processing for outputting the object data from the input / output interface 1040. For example, the output processing unit 1025 performs processing for notifying the number of the registered license plate to the portable terminal 50 associated with the customer ID. The notification is performed, for example, using an e-mail, a power seller application 521, an SNS, etc. Contact information such as the customer ID and the e-mail address is pre-registered in the operation server 100.

[0126] (Power sales processing main storage device)

[0127] The electricity selling processing main storage device 1030 includes a customer ID / license plate receiving unit 1031 , the cumulative number of charging times when selling electricity 1032 , purchase unit price information 1033 , and an output processing unit 1034 .

[0128] The license plate receiving unit 1031 receives the license plate information of the EV30 captured by the camera 90. In addition, the license plate receiving unit 1031 receives the customer ID and the license plate information of the EV30 that has been PV-charged included in the two-dimensional code reading information from the local terminal 80. The information included in the two-dimensional code reading information may be only the license plate information of the EV30.

[0129] The cumulative number of charging times during power selling 1032 is a value obtained from the operation status management server 110 in response to a request from the local terminal 80 when applying for power selling (power supply) of the battery 31 of the EV 30. The operation server 100 transmits the cumulative number of charging times during power selling to the local terminal 80.

[0130] The purchase price information 1033 is information indicating the purchase price when selling the charging power of the battery 31. For example, by establishing a correspondence between the charging amount (kWh) and the purchase price (yen), the purchase amount (reward) corresponding to the charging amount sold from the battery 31 to the power selling device 70 is calculated. Instead of the purchase amount, it may be points that can be used for product purchases or service provision.

[0131] 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 charge amount and the purchase unit price to the power vending device 70 via the local terminal 80.

[0132] The input / output interface 1040 is an interface for performing data communication with the operating status management server 110 and the local terminal 80 .

[0133] [Local terminal structure]

[0134] Next, refer to Fig. 9 The configuration of the local terminal 80 in this embodiment will be described.

[0135] Fig. 9 2 is a block diagram showing a configuration example of the local terminal 80. As the local terminal 80, a general-purpose computer such as a personal computer can be used.

[0136] The local terminal 80 manages information on the commercial facility 60 side, or displays information managed for each facility in the operation server 100, and information on whether or not a purchase is available. The local terminal 80 includes a CPU 810, a main storage device 820, a display unit 830, and an input / output interface 840. Each unit is connected to each other via a system bus or the like so as to be able to communicate with each other. As the local terminal 80, a general-purpose computer such as a personal computer can be used.

[0137] The functions of the CPU 810, the main storage device 820, the display unit 830, and the input / output interface 840 as hardware are as follows: Figure 5 The functions of corresponding elements of the information processing device 40 shown are the same, and duplicate descriptions are omitted as much as possible.

[0138] The main storage device 820 includes a customer information / license plate registration unit 821 , a cumulative number of charging times during charging / electricity sales comparison unit 822 , and an output processing unit 823 .

[0139] The customer information / license plate registration unit 821 registers customer information and the license plate number of the EV30 used by the customer. The customer information / license plate registration unit 821 has a function of recognizing the license plate number based on the license plate number photographed by the camera 90 and the two-dimensional code reading information. For example, the customer information is the customer's name, customer ID, etc. As the customer information, the ownership method of the EV30, that is, legal person ownership or individual ownership, may also be included. However, it is also possible to recognize and register only the license plate information.

[0140] In addition, in the present embodiment, the customer information / license plate registration unit 821 compares the license plate number obtained from the image captured by the camera 90 with the license plate number obtained from the read information of the two-dimensional code. Then, when the two numbers match, the customer information / license plate registration unit 821 instructs the output processing unit 823 to obtain the cumulative number of times the battery 31 associated with the license plate is charged from the operation server 100. However, the function of comparing the license plate number and the function of instructing the acquisition of the cumulative number of times of charging can also be realized by a processing block different from the customer information / license plate registration unit 821.

[0141] The cumulative charging times comparison unit 822 for charging / selling electricity compares the cumulative charging times of the battery 31 when the battery 31 is charged with electricity from renewable energy (PV power in this embodiment) and the cumulative charging times of the battery 31 when the electricity selling device 70 that receives power supply from the battery 31 applies for electricity selling (power supply) based on the battery 31. Then, the cumulative charging times comparison unit 822 for charging / selling electricity determines whether to permit electricity selling (power supply) from the battery 31 to the electricity selling device 70 based on the comparison result. The cumulative charging times comparison unit 822 for charging / selling electricity displays the determination result on the display unit 830 and the display unit 72 of the electricity selling device 70 through the output processing unit 823.

[0142] 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 a purchase permission / non-permission response to the application for selling electricity of the battery 31 to the display unit 830.

[0143] The display unit 830 is a display device such as a liquid crystal display panel, and displays the content managed by each facility by the operation server 100. For example, the display unit 830 displays customer information / license plate management content 831, customer / power sales amount / purchase amount 832, and purchase permission determination result 833.

[0144] The customer information / license plate management content 831 includes the customer ID and the license plate number.

[0145] Customer / power sales amount / purchase amount 832 is information indicating power sales amount and purchase amount for each customer.

[0146] The purchase permission determination result 833 is information indicating the determination result of whether or not to accept the sale (purchase) of electricity for the license plate number of the EV 30 captured by the camera 90 when the customer applied for the sale of electricity.

[0147] The input / output interface 840 is an interface for 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 applying for power selling is charged, and receives the cumulative number of times the battery 31 is charged when selling power from the operation server 100. In addition, the input / output interface 840 sends the decision result of whether to purchase permission / not permission for the power selling application to the power selling device 70.

[0148] Display unit 72 of power vending device 70 displays information such as a result of a purchase permission / non-permission determination and a purchase amount corresponding to a charge amount when the purchase is permitted.

[0149] [Processing of power transfer system]

[0150] Next, refer to Fig.10 An overview of the processing of the power transfer system 1 in the present embodiment will be described.

[0151] Fig.10 1 is a flowchart showing an example of a process procedure of the power transfer system 1 .

[0152] exist Fig.10 In the example, the user of EV30 as a customer connects the battery 31 of EV30 to the charging and discharging device 20 installed in the home 10, and charges the battery 31 of EV30 through the charging and discharging device 20 (S1). At this time, the charging and discharging device 20 sends the power type, charging amount, and charging date and time of the power charged into the battery 31 to the information processing device 40.

[0153] Next, in EV 30 , cumulative charge and discharge frequency update unit 323 updates the cumulative charge frequency. Then, CPU 310 transmits the operation data (including the cumulative charge and discharge frequency during charging) to operation status management server 110 via wireless communication ( S2 ).

[0154] Next, the information processing device 40 transmits the charging and discharging data (for example, the type of power, the amount of charge, and the date and time of charging) to the operation server 100 ( S3 ).

[0155] Next, operation server 100 transmits a two-dimensional code including the license plate number of EV30 to mobile terminal 50 of the user of EV30 (S4). Thereafter, the user drives EV30 to commercial facility 70 and stops in front of power selling device 70 in order to sell the charging power of EV30.

[0156] Next, the user (driver) of EV 30 applies to power vending device 70 for power selling using the charging power of battery 31. EV 30 connected to power vending device 70 transmits a part of the operation data (the accumulated number of charging times during power selling) to operation status management server 110 (S5).

[0157] Next, the user displays the two-dimensional code sent from the operation server 100 to the portable terminal 50 on the screen and places it in front of the camera 71 of the power vending device 70. The power vending device 70 reads the two-dimensional code photographed by the camera 71 and sends 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 obtains the information of the license plate photographed by the camera 90.

[0158] Next, the local terminal 80 requests the operation server 100 to send the cumulative number of times the battery 31 is charged, which is associated with the license plate information. Then, the operation server 100 obtains the cumulative number of times the EV 30 is charged and sold electricity, which is associated with the license plate information, from the operation status management server 110. Then, the operation server 100 sends various information including the cumulative number of times the EV 30 is charged and sold electricity to the local terminal 80 (S7).

[0159] Next, the local terminal 80 determines whether the various information obtained from the operation server 100 satisfies the conditions for accepting power sales, and sends the determination result to the power selling device 70 (S8). If the conditions for accepting power sales are met ("Yes" determination in S8), the local terminal 80 determines that acceptance of power sales is permitted, that is, purchase is permitted (S9). The power selling device 70 accepts the purchase permission and accepts the power from the PV to charge the battery 31 (S10).

[0160] On the other hand, if the conditions for accepting power sales are not met (No judgment in S8), the local terminal 80 judges that power sales are not permitted, that is, purchase is not permitted (S11), and ends the process. After the process in step 10 or S11 is completed, this process ends.

[0161] [Processing by the information processing device]

[0162] Next, refer to Fig.11 The processing of the information processing device 40 in this embodiment will be described.

[0163] Fig.11 It is a flowchart showing an example of the process procedure of the information processing device 40.

[0164] exist Fig.11In the example, the user of EV 30 as a customer connects battery 31 of EV 30 to charging and discharging device 20 provided in home 10 , and starts charging battery 31 of EV 30 through charging and discharging device 20 ( S21 ).

[0165] The charging and discharging device 20 detects that the power supply to the battery 31 is completed, the battery 31 is fully charged, or the charger is disconnected (the connection between the charging and discharging device 20 and the battery 31 is disconnected) (S22).

[0166] 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 and discharge device 20 as charge and discharge data ( S23 ).

[0167] Next, output processing unit 425 of information processing device 40 transmits the customer ID of the user (customer) of EV 30 registered in advance, and the information of the power type (power source) and the charge amount received from charging / discharging device 20 to operation server 100 ( S24 ).

[0168] Next, in the operation server 100, when the customer / power source / charge amount receiving unit 1021 receives the charge and discharge data from the information processing device 40 in step S24, the two-dimensional code issuing unit 1024 issues a two-dimensional code (S25). The two-dimensional code records at least the license plate number of the EV 30 connected to the charge and discharge device 20 during PV charging.

[0169] Next, the output processing unit of operation server 100 transmits the two-dimensional code to mobile terminal 50 of the user of EV 30 by using e-mail or the like ( S26 ). After the process of step S26 is completed, this process ends.

[0170] [Purchase processing at commercial facilities]

[0171] Next, refer to Fig.12 The purchase process on the commercial facility 60 side in this embodiment will be described.

[0172] Fig.12 This is a flowchart showing an example of the sequence of the purchase process on the commercial facility 60 side.

[0173] exist Fig.12 In the example, the camera 90 installed near the power selling device 70 captures the license plate number of the EV 30 equipped with the battery 31 for selling power in the commercial facility 60 (S31). The customer information / license plate registration unit 821 of the local terminal 80 recognizes the license plate number from the captured image of the camera 90.

[0174] Next, the two-dimensional code displayed on the portable terminal 50 of the user of EV30 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 read two-dimensional code is input to the local terminal 80.

[0175] Next, the customer information / license plate registration unit 821 of the local terminal 80 compares the number of the license plate photographed by the camera 90 with the number of the license plate obtained from the read information of the two-dimensional code. Then, when the numbers of the two license plates are consistent, the output processing unit 823 of the local terminal 80 sends the read information of the two-dimensional code, that is, the number of the license plate to the operation server 100 (S33). At this time, the local terminal 80 sends the number of the license plate and requests various information related to charging associated with the number of the license plate (S34).

[0176] Next, the local terminal 80 obtains various information including the cumulative number of times the battery 31 is charged and the cumulative number of times the power is sold from the operation server 100 (S35). The various information includes, for example, the customer ID, the power type (power source), and the charge amount.

[0177] Next, the cumulative charging times comparison unit 822 of the local terminal 80 during charging / power selling confirms that the power of the battery 31 for which power selling has been applied is PV power, and compares the cumulative charging times during charging with the cumulative charging times during power selling to determine whether power selling can be accepted (S36).

[0178] The cumulative charging times comparison unit 822 of the local terminal 80 during charging / selling of electricity determines whether the selling of electricity can be accepted based on the result of the processing in step S36 (S37). When the conditions of the power type and the cumulative charging times of step S36 are met and the selling of electricity can be accepted ("Yes" in S37), the cumulative charging times comparison unit 822 during charging / selling of electricity displays the judgment result that the selling of electricity can be accepted on the display unit 72 of the selling device 70, and notifies the selling device 70 that "the selling of electricity can be accepted". Then, the selling device 70 starts to supply (receive) electricity corresponding to the amount of electricity to be supplied (S38).

[0179] Then, the power vending device 70 performs the power supply process until the power supply is completed (S39). For example, the power vending device 70 charges the power using the charge amount registered in the operation server 100 as the maximum value during PV charging. After the power supply is completed, this process ends.

[0180] In addition, when the electricity sale is unacceptable (No in S37), the cumulative charging times comparison unit 822 during charging / electricity sale displays the judgment result that the electricity sale is unacceptable on the display unit 72 of the electricity sale device 70, notifies the electricity sale device 70 that "electricity sale is unacceptable" and stops the transaction. When the electricity type is not PV electricity, or when the cumulative charging times during charging and electricity sale are inconsistent, the cumulative charging times comparison unit 822 during charging / electricity sale determines that the electricity sale is unacceptable.

[0181] In addition, when the power category includes PV power and the cumulative charging times when charging and selling power do not match each other (other cases of S37), the charging / selling power cumulative charging times comparison unit 822 regards all power including PV power as general commercial power (S41), and the process proceeds to step S38. In this case, not limited to PV power, a designated charging amount is supplied for the power in the battery 31.

[0182] As described above, the power transfer system (power transfer system 1) of the present embodiment is a power transfer system that uses a storage battery (battery 31) mounted on a mobile body (EV30) to transfer power, and is equipped with a power supply availability determination device (local terminal 80). The power supply availability determination device compares the cumulative number of times the storage battery is charged when the storage battery is charged using power from renewable energy (e.g., PV power) with the cumulative number of times the storage battery is charged when a power supply based on the storage battery is applied to a power receiving device (power selling device 70) that receives power from the storage battery, and determines whether to permit power supply from the storage battery to the power receiving device based on the comparison result.

[0183] According to the above configuration, even when the seller charges the battery of the mobile object at a charging device other than the seller's home, the buyer can identify the source of the power used to charge the battery of the seller's mobile object (the type of energy used to generate electricity). For example, after PV charging at home 10, the commercial power source 2 is charged at a place other than home 10, such as on the way to commercial facility 50, based on the consistency / inconsistency of the cumulative number of power receptions.

[0184] In addition, in the power transfer system (power transfer system 1) of the present embodiment, the mobile object (EV30) includes:

[0185] a cumulative charge and discharge count update unit (cumulative charge and discharge count update unit 323) that updates the cumulative charge count and the cumulative discharge count each time the storage battery is charged and discharged; and

[0186] The output unit (output processing unit 324, input / output interface 330) sends the cumulative charging and discharging times (cumulative charging and discharging times 322) to the operating status management server (operating status management server 110) that manages the operating status of the mobile body via wireless communication when the battery is charged and discharged.

[0187] When requesting the power receiving device to supply power from the storage battery, the output unit transmits the current cumulative number of discharges to the operating status management server.

[0188] When applying for power supply from the storage battery, the power supply availability determination device (local terminal 80) uses the cumulative number of times of charging during charging and the cumulative number of times of power supply managed by the operating status management server.

[0189] In addition, the power transfer system (power transfer system 1) of the present embodiment includes:
