Description

[Technical field]

[0001] The present invention relates to technology that supports environmental value management, and more specifically, to technology that enables companies to more effectively implement environmental measures that apply renewable energy to their own electricity consumption. [Background technology]

[0002] In response to climate change such as global warming, consumers and investors are increasingly evaluating how environmentally conscious companies are in their activities and making purchasing and investment decisions based on this evaluation. In line with this, there are more and more cases of companies working to reduce greenhouse gas emissions and introduce renewable energy, and internationally, efforts such as CDP (a project run by a non-profit organization based in London, operated in cooperation with institutional investors, calling on the top companies in major countries by market capitalization to disclose their environmental strategies and greenhouse gas emissions) and RE100 (an international corporate alliance whose members are working to use 100% renewable energy for the electricity they use) are spreading. In addition, in recent years, there have been efforts to reduce the environmental impact of not only one company but also the entire supply chain of one's own company in terms of supply chain emissions.

[0003] When a company introduces renewable energy into its own electricity usage, one method is to have the electricity retailer with which it has a contract supply it with electricity generated by solar power or hydroelectric power. In addition, there is also a method in which the portion of CO2 emissions reduced when another company introduces renewable energy can be traded as environmental value and applied to the company's own non-renewable electricity usage, thereby being considered to have used renewable energy; in Japan, the J-Credit Scheme is one such example. In either case, the environmental initiative of introducing renewable energy is established by managing the means by which the company introduced the electricity and environmental value generated.

[0004] As an example of prior art related to such environmental value management, Patent Document 1 describes a system that fairly evaluates the environmental value of renewable energy. When a company undertakes environmental initiatives, it can purchase a certificate that is circulated in the manner shown in Patent Document 1. Patent Document 2 also describes an electricity-derived management device as prior art that breaks down the management targets for environmental value down to the equipment level. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2012-38342 A [Patent Document 2] JP 2020-170484 A Summary of the Invention [Problem to be solved by the invention]

[0006] In the conventional technology, there are problems in terms of accuracy and scope for a company to correctly introduce and manage environmental value for the burden on the environment caused by its activities. The conventional technology can only manage extremely limited targets, specifically, the targets are fixed to the company's power supply facilities and the company can easily obtain the amount of power supply to the targets.

[0007] However, there are many different types of electricity usage that do not fit these criteria. For example, electric vehicles (EVs) do not necessarily need to be charged at the company's own power supply facilities, but can be charged at stations or outlets outside the company. Furthermore, in recent years, teleworking, where people work from satellite offices or at home, has become more common, and power is also supplied to laptops outside the company. In the above examples, as electricity is used for business activities, environmental value management should ideally be implemented by the companies that own and operate the EVs and laptops, but this cannot be done with conventional technology.

[0008] In the case of EV charging, there are many parties involved, such as EV manufacturers, leasing companies, users, charging station operators, and electricity retailers, and each party has a certain degree of responsibility for the environmental impact of EV charging. If these parties share the responsibility for the environmental impact and, for example, each party applies an environmental certificate (hereinafter sometimes referred to as the "certificate") equivalent to a portion of the electricity usage, they can carry out environmental initiatives at a lower cost than if a single company were to implement them.

[0009] The object of the present invention is to provide an environmental value management support device and method that realizes environmental value management for a wide range of devices and power sources regarding power supply between devices and power sources, and that enables environmental initiatives to be shared among a large number of stakeholders. [Means for solving the problem]

[0010] A preferred aspect of the present invention is an environmental value management support device having a processor, a memory, a communication device, an input / output device, a storage device, and an internal signal line, and managing information relating to an appliance that consumes power and a power source that supplies power to the appliance, the environmental value management support device comprising: an appliance power data acquisition unit that collects an appliance side log relating to the appliance and a power source side log relating to the power source via the communication device; an appliance power connection identification unit that acquires appliance power connection information that identifies the power supply that has taken place between the appliance and the power source via the communication device; and an appliance power connection identification unit that identifies the appliance based on the appliance side log, the power source side log, and the appliance power connection information. and an environmental value management support device that comprises: a power configuration acquisition unit that integrates environmental values ​​applied in power supply between a device and the power source, generates an integrated power supply log, and stores the log in the storage device; a power supply amount estimation unit that estimates the amount of power supply when the amount of power supply in the integrated power supply log is unknown; and an environmental value allocation unit that compares power configuration information based on the integrated power supply log and the estimated amount of power supply with an environmental value allocation target, which is information on the environmental value to be allocated for power supply, and allocates environmental value that is short of the target in the power configuration information.

[0011] Another preferred aspect of the present invention is a method for supporting management of environmental value, using an information processing device having a processor, memory, a communication device, an input / output device, a storage device, and an internal signal line, to collect and manage information relating to an appliance that consumes power and a power source that supplies power to the appliance in the storage device via a communications network, the method comprising: an appliance power data acquisition step in which the information processing device collects an appliance side log relating to the appliance and a power source side log relating to the power source via the communications network, integrates the two and stores them in the storage device as an individual power supply log; an appliance power connection identification step in which the information processing device acquires appliance power connection information that identifies the power supply performed between the appliance and the power source and stores the information in the storage device; This is an environmental value management support method, which executes the following steps: a power configuration acquisition step of generating an integrated power supply log by integrating the environmental value applied in the power supply between the device and the power source based on the individual power supply log and the device power supply connection information, and storing the generated log in the storage device; a power supply amount estimation step of the information processing device estimating the amount of power supply when the amount of power supply in the integrated power supply log is unknown, and recording the amount in the integrated power supply log; and an environmental value allocation step of the information processing device comparing power configuration information based on the integrated power supply log with an environmental value allocation target, which is information on the environmental value to be allocated for power supply, and allocating the environmental value that is short of the target in the power configuration information. Effect of the Invention

[0012] According to the present invention, it is possible to provide an environmental value management support device and method that realizes environmental value management targeting a wide range of devices and power sources for power supply between devices and power sources, and that enables environmental initiatives to be shared among a large number of stakeholders.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] The embodiments will be described in detail with reference to the drawings. However, the present invention should not be interpreted as being limited to the description of the embodiments shown below. It will be easily understood by those skilled in the art that the specific configuration can be changed without departing from the concept or purpose of the present invention.

[0015] In the configurations of the embodiments described below, the same parts or parts having similar functions are denoted by the same reference numerals in different drawings, and duplicated explanations may be omitted.

[0016] When there are multiple elements having the same or similar functions, they may be described by using the same reference numerals with different subscripts. However, when there is no need to distinguish between multiple elements, the subscripts may be omitted.

[0017] The designations "first," "second," "third," and the like in this specification are given to identify components, and do not necessarily limit the number, order, or content. Furthermore, numbers for identifying components are used in different contexts, and a number used in one context does not necessarily indicate the same configuration in another context. Furthermore, a component identified by a certain number does not prevent the component from also having the function of a component identified by another number.

[0018] In order to facilitate understanding of the invention, the position, size, shape, range, etc. of each component shown in the drawings, etc. may not represent the actual position, size, shape, range, etc. Therefore, the present invention is not necessarily limited to the position, size, shape, range, etc. disclosed in the drawings, etc.

[0019] All publications, patents, and patent applications cited herein are hereby incorporated by reference in their entirety.

[0020] As used herein, elements referred to in the singular are intended to include the plural unless the context clearly indicates otherwise.

[0021] An example of the embodiment described below is an environmental value management support device that supports the introduction of environmental values ​​in the power usage of a company. This device has an equipment power data acquisition unit that collects information on equipment and power sources, an equipment power connection identification unit that identifies which equipment and which power source the power supply that the user wants to manage has been connected to, a power configuration acquisition unit that integrates what environmental value has been applied to various subjects related to the power supply, a power supply amount estimation unit that performs estimation when the power supply amount is unknown, and an environmental value allocation unit that compares the power configuration information acquired by the power configuration acquisition unit and the power supply amount estimation unit with an environmental value allocation target and allocates an environmental value when there is a shortage.

[0022] The technology described in the embodiments makes it possible to estimate the amount of power supply when it is unknown for a wide range of combinations of equipment and power sources, including those whose power amount cannot be measured. It also makes it possible to visualize the environmental value that has already been assigned by related parties and the environmental value that should be assigned by one's own company, and to assign it based on that, thereby promoting efficient environmental efforts in companies.

[0023] The concept of environmental value proposed in recent years is as follows. Electricity obtained from fossil fuels or nuclear power and electricity obtained from renewable energy sources such as solar or wind power are the same as "electricity", but electricity from renewable energy sources is called green power, and in addition to the "value of electricity or heat itself", it has the "environmental value" of not emitting carbon dioxide. Therefore, it is possible to extract the "environmental value" portion and treat it as a "certificate" that has economic value. In this embodiment, the "environmental value" and "certificate" are specifically finite values ​​(data) that can be assigned to electricity. As a unit of environmental value, for example, the J-credit is set to a unit for the amount of CO2 reduced. Alternatively, other units may be used, such as converting to the amount of electricity supplied or converting to the ratio of renewable energy in the amount of electricity supplied.

[0024] By purchasing such a certificate, the electricity used can be considered to have been supplied from renewable energy sources, which corresponds to the purchased "environmental value." As a prerequisite for such a system, consumers and businesses need to know how much of the electricity they use is derived from renewable energy sources. EXAMPLES

[0025] Hereinafter, the embodiments will be described with reference to the drawings. However, aspects that can be implemented by partially modifying the embodiments will be described as modified examples within each embodiment.

[0026] 1 shows a schematic configuration of an information processing system 1 according to the embodiment 1. The information processing system 1 includes an environmental value management support device (hereinafter, "support device 10"), one or more equipment side servers 2, one or more power source side servers 3, and one or more power procurement management servers 4. All of these are information communication devices (computers) and are connected via a communication network 5.

[0027] The support device 10 and each server may be configured as a stand-alone computer, or any part of the input device, output device, processing device, and storage device may be configured as another computer connected via a communication network 5.

[0028] 2 shows the main functions of the support device 10, the device-side server 2, the power source-side server 3, and the power procurement management server 4. As shown in FIG. 2, the support device 10 has the functions of an equipment power source data acquisition unit 111, an equipment power source connection identification unit 112, a power configuration acquisition unit 113, a power supply amount estimation unit 114, and an environmental value allocation unit 115.

[0029] As will be explained later in Fig. 7, each function of the support device 10 can be configured by a general server having a processor, memory, communication device, input / output device, storage device, and internal signal lines. An equipment power supply data acquisition unit 111, an equipment power supply connection identification unit 112, a power configuration acquisition unit 113, a power supply amount estimation unit 114, and an environmental value allocation unit 115, which are indicated by dotted lines, are realized by the processor executing a program stored in the memory. Equipment power supply connection information 151, an environmental value allocation target 152, an environmental value allocation result 153, an individual power supply log T600, and an integrated power supply log T1000 are stored as data in the storage device.

[0030] The device-side server 2 manages information on devices that have received power supply, which may be a target for the system to manage the amount of power supply and environmental value. The device-side server 2 may be configured as a general server having a processor, memory, a communication device, an input / output device, a storage device, and an internal signal line. The device-side server 2 collects and stores data on various device-side logs 121, a device information list 122, a device location information history 123, and specification information for estimating the amount of power supply 124, and provides the data to the support device 10. The information present in the device-side server 2 may be provided by parties involved in the devices (manufacturers, sellers, users, etc.).

[0031] The power supply server 3 manages information about the power source that supplied the power supply that may be managed by the system. The power supply server 3 may be configured as a general server having a processor, memory, a communication device, an input / output device, a storage device, and an internal signal line. The power supply server 3 collects and stores data such as various power supply side logs 131, a power supply information list 132, specification information for estimating power supply amount 134, electrical system structure information for differential measurement 135, and a differential measurement log 136, and provides the data to the support device 10. The information stored in the power supply server 3 may be provided by parties involved in the power supply (manufacturers, providers, etc.).

[0032] 3 is a diagram showing an example of the configuration of the device side log 121. The user can arbitrarily set the target device as a device to be supplied with power, such as an EV, a smartphone, a laptop PC, a grass cutter, or factory equipment. In this embodiment, power is supplied in a one-to-one relationship between one power source and one device. The supply of power is not limited to charging, and may be a case where the supplied power is immediately consumed.

[0033] The device-side log 121 stores information as shown in Fig. 3. In the example of Fig. 3, information includes charging start time 311, charging end time 312, device ID 313 of the device being charged, power source ID 314, data manager 315, power supply amount 316, location 317, and renewable energy ratio (renewable energy ratio) 318 of the charged energy. This is one example, and there may be missing data or additional data. The information of the device-side log 121 is obtained, for example, by a device to which power is supplied using a known method, and is collected by the device-side server 2 via the communication network 5.

[0034] Except for the start time 311, end time 312, device ID 313, and data administrator 315, the power source ID 314, power supply amount 316, location 317, and renewable energy ratio 318 may be missing (#2, #3, and #4 in FIG. 3).

[0035] For the power source ID 314, power supply amount 316, and renewable energy ratio 318, information must be obtained from the power source or input separately. The power supply amount 316 may be measured by the device itself. For the location 317, if the location is not fixed, the device must have a function for measuring the location (for example, GPS (Global Positioning System)). If no information can be obtained, this is shown as unknown in FIG. 3 (#3 in FIG. 3).

[0036] The data manager 315 indicates the actor who manages the data for each line of the log, and for example, for an EV, the data manager could be the EV manufacturer, leasing company, user, etc. There may be different logs by multiple data managers for the same power supply.

[0037] The renewable energy ratio 318 indicates the ratio of electricity that is considered to have been generated by renewable energy, for which the data administrator 315 has purchased renewable energy or implemented the application of an environmental certificate as an alternative to renewable energy.

[0038] 4 is a diagram showing an example of the configuration of the power source side log 131. The user can arbitrarily set the target power source to an EV charger, a green outlet, a storage battery, an outlet, or the like.

[0039] The power source side log 131 stores information as shown in Fig. 4. In the example of Fig. 4, information includes charging start time 321, charging end time 322, device ID 323 of the device being charged, power source ID 324, data manager 325, power supply amount 326, location 327, and renewable energy ratio (renewable energy ratio) 328 of the charged energy. This is one example, and there may be missing data or additional data. The information of the power source side log 131 is obtained, for example, by the power source using a known method, and collected by the power source side server 3 via the communication network 5.

[0040] Except for the fact that the information that may be missing is the device ID 323 instead of the power source ID 324, it is basically the same as the device side log 121 of the device side server (#2, #3, #4 in FIG. 4). Note that if the power source side measures the power supply amount 326 of the charged electricity and the renewable energy ratio 328, these can be included in the data.

[0041] Fig. 5 is a diagram showing an example of the configuration of the device information list 122. In the example of Fig. 5, the device information list 122 includes information on the device ID of the device to be charged, the data administrator 412 of the device, the location 413 of the device, the renewable energy certification (renewable energy certification) 414 of the device, the renewable energy ratio 415 of the device, and the type 416 of the device. The information in the device information list 122 is stored in the device side server 2, for example, by the administrator of the device side server 2, who collects and organizes information provided by the data administrator.

[0042] Unlike the device side log 121, the device information list 122 manages information that does not change over time. Data other than the device ID 411 and data manager 412 may be missing. If the position 413 is constant regardless of time, its value may be recorded in the device information list 122, but if the value varies depending on time, it is recorded as unknown. The information shown in Fig. 5 is minimal, and other information related to the device, such as the device model number and manufacturer, may be stored.

[0043] Renewable energy certification 414 indicates whether the data administrator 412 has guaranteed in some way that the power used by the device is 100% renewable energy and has certified it.

[0044] The renewable energy ratio 415 is the same as the renewable energy ratio 318 in the device side log 121, and is recorded in 415 if it is a constant ratio regardless of time.

[0045] Fig. 6 is a diagram showing an example of the configuration of the power source information list 132. In the example of Fig. 6, the device information list 421 includes information on the power source ID of the power source to be charged, the data manager 422 of the device, the location 423 of the device, the renewable energy authentication 424 of the device, the renewable energy ratio 425 of the device, and the type 426 of the device.

[0046] The power supply information list 132 is basically the same as the device information list 1221, except that a power supply ID 421 is used instead of the device ID 411 in the device information list 122. The information in the power supply information list 132 is stored in the power supply server 3, for example, by an administrator of the power supply server 3 who collects and organizes information provided by a data administrator.

[0047] 1 and 2, the power procurement management server 4 provides the support device 10 with an environmental value reserve 141 that can be allocated by the system. The power procurement management server 4 can be configured as a general server having a processor, memory, a communication device, an input / output device, a storage device, and an internal signal line. The environmental value reserve 141 is held by a user who uses the system, and manages the type and amount of environmental value that can be applied by the system.

[0048] In FIG. 2, the storage device of the support device 10 stores device power connection information 151, an environmental value allocation target 152, an environmental value allocation result 153, an individual power supply log T600, and an integrated power supply log T1000.

[0049] Information indicating that a connection between a device and a power source and power supply has been performed is managed in the device power connection information 151. The device power connection information 151 will be described later with reference to FIG.

[0050] The environmental value allocation target 152 manages information indicating the conditions (device, date and time, power source, etc.) to which an environmental value should be allocated and the ratio of the environmental value to the amount of power supply managed by the system. The environmental value allocation target 152 is information acquired by, for example, an operational input from a user. The environmental value allocation target 152 will be described later with reference to FIG. 22.

[0051] The environmental value allocation result 153 manages information on the date and time, the device, the power source, and the power configuration for the amount of power supply that is the subject of management by the system. The environmental value allocation result 153 will be described later with reference to FIG.

[0052] The individual power supply log T600 is an intermediate product obtained during the processing of the device power data acquisition unit 111 and the device power connection identification unit 112. First, it is generated as a result of the processing of the device power data acquisition unit 111, and then records are edited as appropriate as a result of each processing of the device power connection identification unit 112. The individual power supply log T600 will be described later with reference to FIG.

[0053] The power supply integrated log T1000 is an intermediate product obtained as a result of processing by the power configuration acquisition unit 113 and the power supply amount estimation unit 114. It is generated from the power supply individual log T600 by the power configuration acquisition unit 113, and is appropriately edited by the power supply amount estimation unit 114. The power supply integrated log T1000 will be described later with reference to FIG.

[0054] Among the functions of the support device 10 shown in FIG. 2, the device power data acquisition unit 111 acquires information on the device side server 2 and the power supply side server 3 via the communication network 5, and generates an individual power supply log T600 based on the information.

[0055] If the power supply ID or device ID is unknown in the individual power supply log T600, the device power connection identification unit 112 estimates it using the device power connection information 151 and information from the device side server 2 and the power supply side server 3, and updates the individual power supply log T600.

[0056] The power configuration acquisition unit 113 replaces some of the items that are unknown in the individual power supply log T600 with default values, and also integrates multiple records that handle the same power supply, calculates the renewable energy ratio and renewable energy adopters for each power supply, and generates the integrated power supply log T1000.

[0057] When the power supply amount is unknown in the power supply integrated log T1000, the power supply amount estimation unit 114 acquires and utilizes the device location information history 123 of the device side server 2, specification information for power supply amount estimation 124, specification information for power supply amount estimation 134 of the power supply side server 3, and electrical system structure information for differential measurement 135 to estimate the power supply amount and update the power supply integrated log T1000.

[0058] The environmental value allocation unit 115 acquires the corresponding record from the integrated power supply log T1000 for each of the targets to be managed specified by the environmental value allocation target 152, and determines whether the renewable energy ratio meets the target. If it does not, it refers to the environmental value reserve 141 acquired via the communication network 5, allocates the environmental value, and outputs the environmental value allocation result 153.

[0059] Fig. 7 is a diagram showing an example of a hardware configuration of the support device 10 of Fig. 1. The support device 10 has a processor 21, a memory 22, a communication device 23, an input / output device 24, a storage device 25, and an internal signal line 26. The input / output device 24 is connected to a monitor 27, a keyboard 28, and a mouse 29.

[0060] The memory 22 is composed of a volatile storage medium such as DRAM, and stores an equipment power supply data acquisition program 711, an equipment power supply connection identification program 712, a power configuration acquisition program 713, a power supply amount estimation program 714, and an environmental value allocation program 715. The programs stored in the memory 22 are executed by the processor 21, which is a processing unit, to realize each of the functions of the equipment power supply data acquisition unit 111, the equipment power supply connection identification unit 112, the power configuration acquisition unit 113, the power supply amount estimation unit 114, and the environmental value allocation unit 115 shown in Fig. 2. In this embodiment, each function is implemented by software, but it may also be implemented by hardware.

[0061] The storage device 25 is configured with a non-volatile storage medium such as a hard disk drive, and stores device power connection information 151, environmental value allocation target 152, environmental value allocation result 153, individual power supply log T600, and integrated power supply log T1000.

[0062] Next, the processing performed by the support device 10 will be described. The main processing performed by the support device 10 is roughly divided into processing for generating an integrated power supply log T1000 based on information from the device-side server 2 and the power source-side server 3 (hereinafter referred to as "power supply log generation processing S500"), and processing for generating an environmental value allocation result 153 based on the environmental value allocation target 152 and the integrated power supply log T1000 (hereinafter referred to as "environmental value allocation processing S1700"). These processing are performed at regular intervals, for example once a month, according to the unit in which the user of the system manages the environmental value.

[0063] 8 is a flowchart for explaining the power supply log generation process S500. The support device 10 executes the process S500 to generate an integrated power supply log T1000.

[0064] First, the device power data acquisition unit 111 acquires the device side log 121 and the power side log 131 for the period to be managed in the current process from the device side server 2 and the power side server 3 (S511).

[0065] Next, the device power data acquisition unit 111 generates records of the individual power supply log T600 based on all the records of the acquired log (S512).

[0066] Fig. 9 is an example of the power supply individual log T600. In S512, for each item including those that are unknown, records acquired from the device side log 121 of the device side server and the power side log 131 of the power supply side server are transcribed. For example, the entries #1 to #4 in Fig. 9 are transcriptions of the device side log 121 of the device side server in Fig. 3, and the entries #5 to #8 are transcriptions of the power side log 131 of the power supply side server in Fig. 4.

[0067] In addition, for renewable energy certification 619, the equipment power source data acquisition unit 111 searches the equipment information list 122 or the power source information list 132 based on the equipment ID 613 or the power source ID 614 of the record, and acquires and records whether or not renewable energy certification has been performed for the relevant equipment or power source.

[0068] 8, the device power connection identification unit 112 determines whether either the device ID 613 or the power source ID 614 is unknown in the records of the individual power supply log T600 (S513). The processes from S513 to S514 are performed for each record of the individual power supply log T600. In the individual power supply log T600 of FIG. 9, either the device ID 613 or the power source ID 614 is unknown in the cases of #2 and #6.

[0069] Next, if either the device ID 613 or the power supply ID 614 is unknown in S513, the device power connection identification unit 112 estimates the unknown ID using the device power connection information 151 and the information of the device side server 2 and the power supply side server 3 (S514). Details of the process of S514 are shown in FIG.

[0070] Next, the power configuration acquisition unit 113 integrates a plurality of records representing the same power supply in the individual power supply log T600 to generate an integrated power supply log T1000 (S515). Details of the process of S515 are shown in FIG.

[0071] Next, the power supply amount estimating unit 114 determines whether or not the power supply amount 616 is unknown in the record of the integrated power supply log T1000 (S516). S516 and S517 are performed for each record of the integrated power supply log T1000.

[0072] Next, if the power supply amount 616 is unknown in S516, the power supply amount estimation unit 114 estimates the unknown power supply amount using the device location information history 123, the device side specification information for estimating power supply amount 124, and the power source side specification information for estimating power supply amount 134 (S517). Details of the process of S517 are shown in FIG.

[0073] Next, the power supply amount estimating unit 114 determines whether or not the power supply amount 616 is unknown in the record of the integrated power supply log T1000 (S518). S518 and S519 are performed for each record of the integrated power supply log T1000.

[0074] Next, if the power supply amount 616 is unknown in S518, the power supply amount estimation unit 114 estimates the unknown power supply amount using the differential measurement electric system structure information 135 and the differential measurement log 136 (S519). Details of the process of S519 are shown in FIG.

[0075] This concludes the explanation of the power supply log generation process S500.

[0076] 10 is a flowchart for explaining the process S514 in which the device power connection identification unit 112 estimates the unknown device ID 613 or power source ID 614. The device power connection identification unit 112 estimates the unknown device ID 613 or power source ID 614 using the device power connection information 151 and information on the device side server 2 and the power source side server 3. S514 is performed for each record of the individual power supply log T600.

[0077] First, the device power connection identification unit 112 searches the device power connection information 151 based on the start time 611, end time 612, and the device ID 613 or power ID 614 that is not unknown, and determines whether there is any relevant information (S711). An appropriate margin may be allowed for the start time 611 and end time 612.

[0078] 11 is an example of device power connection information 151. When a device is fixedly installed and is always connected to a specific power source, the device power connection information 151 is registered (case #3 in FIG. 11). Also, information known in advance may be recorded, such as when charging is performed periodically between a specific power source and the device. Device power connection information 151 can be collected via communication network 5.

[0079] Furthermore, when the device is connected to a power source to be charged, if the charge is processed using a smartphone or the like, authentication can be performed using the device such as the smartphone, and the IDs of the power source and device can be read and recorded at that time (cases #1 and #2 in FIG. 11). A QR code (registered trademark) or an RFID (Radio Frequency Identifier) ​​can be used to read the IDs.

[0080] Category 818 indicates the category of the source of the connection information. The category definition can be set arbitrarily. It is assumed that the charging power source and the device to be charged have a one-to-one correspondence.

[0081] The application start time 811 and application end time 812 indicate the period during which the connection between the device and the power source is maintained, and if the connection is not released after it is made, or if it is always connected, the data for the application end time 812 will be blank (-). This can occur, for example, in the case of a device that is fixed in a factory (e.g., case #3). In the search in S711, connection information whose start time 611 and end time 612 are between the application start time 811 and application end time 812 are targeted.

[0082] The device power connection information 151 is effective for associating the two logs when either the device ID or the power supply ID is not identified in the device side log 121 and the power supply side log 131. There are two possible reasons why the device ID or the power supply ID is missing in the device side log 121 and the power supply side log 131. The first is when the device or the power supply does not have the function to identify the ID. The second is when the ID has not been assigned in the system or is unknown. The second case is sometimes referred to as "no ID" in this embodiment.

[0083] As described above, even if the device ID or power supply ID is missing in the device side log 121 and the power supply side log 131, there are two possible patterns for recording information in the device power connection information 151 to enable association of the two logs.

[0084] The first pattern is a case where both the device ID 813 and the power source ID 814 are known (cases #1 and #3 in FIG. 11).

[0085] The second pattern is when no ID has been assigned to either the equipment or the power source, but it is known that it has been renewable energy certified (case #2 in FIG. 11). In this case, renewable energy certification 815 is set to "True," and the certified side (equipment or power source) must be listed in renewable energy certification target 816. Also, "No ID" is listed for either the equipment ID 813 or power source ID 814 that does not have an ID. As mentioned earlier, "No ID" is different from "unknown" in terms of data.

[0086] 10, next, in S711, if a search based on the connection time finds that the corresponding information exists in the device power connection information 151, the device power connection identification unit 112 replaces the unknown device ID or power supply ID in the individual power supply log T600 with the information in the device power connection information 151 (S712). Here, in S712, the replacement is performed even if one of the IDs in the device power connection information 151 is "no ID."

[0087] For example, suppose that in S513 of Fig. 8, it is found that the power supply ID of #2 in the individual power supply log T600 of Fig. 9 is unknown. In S711 of Fig. 10, the device power connection information 151 is searched for the connection time of #2 in Fig. 9, "2020 / 4 / 1 14:00 to 2020 / 4 / 1 15:00". Then, the case of #2 is extracted from the device power connection information 151 of Fig. 11. Since the power supply ID 814 of #2 in Fig. 11 is "no ID", "unknown" in the power supply ID 614 of #2 in Fig. 9 is replaced with "no ID".

[0088] Next, the device power connection identification unit 112 determines whether or not either the device ID 813 or the power ID 814 in the information acquired in S711 is "no ID" (S713). In the above example, it is determined that the power ID 614 of #2 in FIG. 9 is "no ID".

[0089] Next, in S713, if any of the IDs is "no ID", the device power connection identification unit 112 generates a new record in the power supply individual log T600 (S714). As described above, S714 is performed when the device or power source with "no ID" is given renewable energy certification.

[0090] The record of the individual power supply log T600 generated in S713 will be described with reference to Fig. 9. #9 in Fig. 9 is assumed to be a newly generated record. The start time 611, end time 612, device ID 613, power source ID 614, power supply amount 616, and location information 617 are transcribed to be the same as those at the end of S712 for the record (#2 in this example) that is the subject of processing in S514 and therefore S711. At the end of S712, the power source ID 614 for #2 has been replaced with "no ID".

[0091] For the data administrator 615, if the renewable energy certification manager 817 in the equipment power source connection information 151 is not unknown, that value is entered, and if it is unknown, "unknown (equipment)" or "unknown (power source)" is entered in accordance with the renewable energy certification target 816. In the above example, the renewable energy certification manager 817 "XX stand" in #2 in FIG. 11 is entered together with the renewable energy certification target 816 "power source". As the renewable energy certification 619 has been certified, "True" is entered, and the renewable energy ratio 618 is entered as "100". By assigning the ID "no ID", it is possible to take into account equipment and power sources that have been assigned an environmental value, even if they are not defined in the system.

[0092] If an equipment or power source is not defined in the system, even if the person in charge (817) has obtained renewable energy certification and bears the environmental value, the record will not be registered in the equipment side log 121 and the power source side log 131. Therefore, as the information on the renewable energy certification 815 by the renewable energy certification person in charge 817 will be missing if left as is, a new record is generated in S714.

[0093] Returning to FIG. 10, if the corresponding information does not exist in the equipment power connection information 151 in S711, the equipment power connection identification unit 112 determines whether the position information 617 is unknown (S715).

[0094] Next, if the location information 617 is not unknown in S715, the device power connection identification unit 112 searches the device side log 121 and device information list 122, or the power source side log 131 and power source information list 132, using the location information 617 as a key (S716). Note that it is sufficient to search only the unknown side of the device ID 613 or power source ID 614.

[0095] Next, the device power connection identification unit 112 determines whether or not there was a device or power source located sufficiently close to the location information 617 between the start time 611 and the end time 612 (S717). Whether or not it is sufficiently close can be determined by whether or not it is within a certain distance, taking into account an error in the location information.

[0096] Next, if a device or power source is found to be sufficiently close in S717, the device power source connection identification unit 112 obtains the ID (including "no ID") of the closest device or power source and replaces the device ID 613 or power source ID 614 (S718).

[0097] Next, if there is no device or power source located sufficiently close in S716, the device power connection identification unit 112 sets the unknown device ID 613 or power source ID 614 to unknown (S719). In other words, if it is originally described as unknown, there is no corresponding information in S711, and there is no device or power source located sufficiently close in S717, it is simply set to unknown in S719. This concludes the explanation of the process S514.

[0098] 12 is a flowchart for explaining the process S515 of the power configuration acquisition unit 113. The power configuration acquisition unit 113 integrates a plurality of records representing the same power supply in the individual power supply log T600, and generates an integrated power supply log T1000.

[0099] First, the power configuration acquisition unit 113 replaces the renewable energy ratio 618 with "0" if it is unknown, and the renewable energy authentication 619 with "false" if it is unknown, for a record of the power supply individual log T600 (S911).

[0100] Next, the power configuration acquisition unit 113 acquires one record from the power supply individual log T600 (S912). At this time, if there is data in the power supply individual log T600 in which the device ID 613 is not unknown and the power source ID 614 is not unknown, the data is acquired. For example, the record #3 in the power supply individual log T600 in FIG. 9 is acquired.

[0101] Next, the power configuration acquisition unit 113 acquires from the individual power supply log T600 all records whose start time 611 and end time 612 are the same as or close to within a predetermined margin as the record acquired in S912, and whose device ID 613 or power source ID 614 are the same (S913). By S913, all records related to the same power supply as the record acquired in S912 are acquired. For example, record #7 of the individual power supply log T600 in FIG. 9 is acquired.

[0102] Next, the power configuration acquisition unit 113 generates a record in the power supply integrated log T1000 based on the records acquired in S912 and S913 (S914).

[0103] FIG. 13 shows an example of the power supply integrated log T1000.

[0104] In S914 of Fig. 12, one or more records acquired in S912 and S913 are combined into one record. For the start time 1011, end time 1012, device ID 1013, and power source ID 1014, items with the same names in the data of one record acquired in S912 are transcribed into the power supply integrated log T1000. All records acquired in S912 have the same start time and end time, and the device ID or power source ID is the same, so no contradictions occur. In the above example, record #3 of the individual power supply log T600 in Fig. 9 is transcribed.

[0105] For the power supply amount 1016, the location 1017, and the renewable energy authentication 1019, if a value other than unknown exists in any record, this is transcribed, and if all are unknown, it is set to unknown. In the above example, the renewable energy ratio 618 "30" of record #7 of the power supply individual log T600 in Fig. 9 is transcribed.

[0106] The renewable energy ratio 1018 is the sum of the renewable energy ratios of all records, and if it exceeds 100[%], it is set to "100". For example, in the case where "the leasing company purchases and applies renewable energy (certificate) equivalent to 10% of the EV's charging amount" and "the charging station supplies 50% of the power supply amount with renewable energy", there are logs for the power supply of a certain EV, such as "the data manager is the leasing company, and the renewable energy ratio is 10%" and "the data manager is the charging station, and the renewable energy ratio is 50%". Therefore, by integrating these, it is possible to create an integrated power supply log in which 60% has already been borne by the leasing company and the charging station. Then, if 100% is the target value, the remaining 40% can be compensated by further allocating environmental value, etc. Conventionally, it was not possible to integrate the renewable energy ratio as in this embodiment, so the leasing company could only recognize the 10% that it was borne by itself, and there was a risk that it would procure the remaining 90% of environmental value and bear unnecessary expenses for 50%.

[0107] The renewable energy manager 1020 records a pair of the data administrator 615 and the renewable energy ratio 618 in a record where the renewable energy ratio is not “0” in the power supply integrated log T1000. For example, in the example of #3 in Fig. 13, the renewable energy ratio 1018 is 50%, which is the sum of 20% paid by company P and 30% paid by company Q.

[0108] In addition, in one-to-one power supply, the renewable energy ratio 1018 is often the total of the power source side and the equipment side. In this case, the number of people who bear the environmental value is two. There may also be three or more people who bear the environmental value. For example, if the equipment side is a leased EV, the renter and the lender each bear the environmental value, and there may be two or more people who bear the environmental value on the equipment side. In FIG. 13, only the total value of the renewable energy ratio and the renewable energy manager 1020 as the data manager are shown, but the information may also include the ratio for each person who actually applied the environmental value.

[0109] Next, the power configuration acquisition unit 113 deletes all records of the power supply individual log T600 acquired in S912 and S913 and used to generate the log in S914 from the power supply individual log T600 (S915).

[0110] Next, the power configuration acquisition unit 113 judges whether or not any records remain in the power supply individual log T600 (S916). If any records remain, the process returns to S912 and acquires the records again. If no records remain, the process ends.

[0111] This is the end of the explanation of process S515.

[0112] FIG. 14 is a flowchart for explaining the process S517 of the power supply amount estimation unit 114.

[0113] First, the power supply amount estimating unit 114 determines whether the device ID 1013 in the record of the target integrated power supply log T1000 is unknown (S1111).

[0114] Next, if the device ID 1013 is not unknown in S1111, the power supply amount estimator 114 searches the device information list 122 based on the device ID 1013 (S1112).

[0115] Next, the power supply amount estimating unit 114 determines whether the device is an EV based on the type 416 in the device information list searched in S1112 (S1113).

[0116] Next, if it is determined in S1113 that the device is an EV, the power supply amount estimation unit 114 estimates the upper and lower limits of the power supply amount by using the device location information history 125 of the device-side server 2 (S1114).

[0117] As a method of estimation in S1114, for example, the following estimation is possible.

[0118] First, the driving history after the EV was last charged is obtained from the device location information history 125, and the upper and lower bounds of the remaining charge at that time are estimated based on the driving distance, speed, etc. in the history. Here, the upper bound refers to a value larger than the range that the actual value can take, and the lower bound refers to a value smaller than the range that the actual value can take. By obtaining the maximum charging capacity from the power supply amount estimation specification information 124 of the device-side server 2 and this, the upper and lower bounds of the power supply amount can be estimated as the maximum charging capacity - the remaining charge. Alternatively, estimation may be performed using other methods that use the device location information history 125.

[0119] Next, the power supply amount estimating unit 114 searches the power supply amount estimation specification information 124 and 134 based on the device ID 1013 and the power source ID 1014, and acquires the corresponding specification information (S1115).

[0120] 15 is an example of the device-side power supply amount estimation specification information 124. For a device ID 1211, a specification information name 1212, an upper bound / lower bound 1213, a numerical value 1214, and a calculation method 1215 are described. This information is registered in advance by an administrator who knows the device specifications.

[0121] Fig. 16 is an example of power supply side power supply amount estimation specification information 134. It is basically the same as Fig. 15 except that a power supply ID 1221 is used instead of the device ID 1211. This information is registered in advance by an administrator who knows the specifications of the power supply.

[0122] 14, the power supply amount estimation unit 114 then estimates an upper or lower limit of the power supply amount based on the calculation means 1215 of the specification information 124 for estimating power supply amount or the calculation means 1225 of the specification information 134 acquired (S1116). S1116 is executed for each piece of specification information acquired in S1115.

[0123] As a method of estimation in S1116, for example, in the case of the charging capacity in Fig. 15, there is no calculation means, and the charging capacity itself is an estimated value of the power supply amount. Therefore, 120 [kWh] is obtained as the upper limit of the power supply amount.

[0124] For example, in the case of the rating in FIG. 15, the calculation means is × (time), so the upper limit of the power supply amount is calculated by multiplying 10 kW stated in the specification information by the time in the integrated power supply log T1000, that is, the difference between the end time 1012 and the start time 1011.

[0125] Next, returning to FIG. 14, the power supply estimation unit 114 selects one each from the upper and lower bounds of the power supply estimated in S1114 and S1116, and enters them in the estimated supply upper bound 1021 and the estimated supply lower bound 1022 of the integrated power supply log T1000 (S1117).

[0126] Here, since the upper bounds obtained in S1114 and S1116 are values ​​larger than the actual power supply, the smallest value of the upper bounds can be selected to obtain an estimate that is close to the actual amount of power supply. Similarly, the largest value can be selected for the lower bound.

[0127] This completes the explanation of process 517.

[0128] FIG. 17 is a flowchart for explaining the process S519 of the power supply amount estimation unit 114.

[0129] First, the power supply amount estimation unit 114 determines whether the power source ID 1014 is "unknown" in the record of the target integrated power supply log (S1311).

[0130] Next, if the power source ID 1014 is not unknown in S1311, the power supply amount estimator 114 searches the electric system structure information for differential measurement 135 based on the power source ID 1014 (S1312).

[0131] 18 is an example of the electrical system structure information for differential measurement 135. It lists an application start time 1411, an application end time 1412, a lower power source list 1413, and a higher measurement unit 1414. The lower power source list 1413 is a list made up of a plurality of power source IDs, and in S1312 a search is performed based on whether the power source ID 1014 corresponds to this list.

[0132] The upper measurement unit 1414 indicates the ID of a higher-level measurement unit that is composed of multiple power sources. For example, if there are power sources X1 and X2 in room A, and the total power supply of power sources X1 and X2 can be measured by a power meter in room A, then room A corresponds to the upper measurement unit, and power sources X1 and X2 correspond to the lower power sources.

[0133] Returning to FIG. 17, the power supply amount estimator 114 then determines whether or not information corresponding to the power source ID 1014 is present in the differential measurement electric system structure information 135 (S1313).

[0134] Next, if the relevant information is acquired in S1312, the power supply estimation unit 114 searches the differential measurement log 136 for logs of the acquired higher-level measurement unit 1414 during the period overlapping with the start time 1011 and end time 1012, and acquires the relevant record (S1314).

[0135] 19 shows an example of the differential measurement log 136. A start time 1511, an end time 1512, a measurement unit 1513, and an amount of power supply 1514 are recorded.

[0136] Returning to FIG. 13, the power supply amount estimation unit 114 then calculates the amount of power supply in the upper measurement unit 1414 from the record acquired in S1314 (S1315).

[0137] Here, the calculation of the power supply amount in S1315 will be described. Since the upper measurement unit 1414 handles power supplies from different power sources, the start time 1011 and end time 1012 in the record of the integrated power supply log T1000 may differ from the start time 1511 and end time 1512 in the record acquired in S1314.

[0138] For the record acquired in S1313, if the start time 1511 and end time 1512 are completely included in the period between the start time 1011 and end time 1012 in the record of the integrated power supply log T1000, the amount of power supply shall be the power supply amount 1514 of the record acquired in S1313 itself.

[0139] In addition, for the record acquired in S1314, if the start time 1511 and end time 1512 fall outside the period between the start time 1011 and end time 1012 in the record of the integrated power supply log T1000, the ratio of the overlapping period to the period between the start time 1511 and end time 1512 is calculated by multiplying it by the amount of power supply 1514.

[0140] If there are multiple records obtained in S1314, the power supply amounts of the respective records calculated by the above procedure are added together. If there are no records obtained in S1314, there is no power supply during that time period, so the power supply amount is calculated as 0.

[0141] Through the above procedure, the amount of power supply in the upper measurement unit 1414 is calculated in S1315.

[0142] Next, the power supply amount estimation unit 114 searches the integrated power supply log T1000 for logs of each power source ID in the acquired lower power source list 1413 during the period overlapping with the start time 1011 and end time 1012, and acquires the corresponding records (S1316), except for the power source ID 1014 used in the search in S1312, which is the original target of the difference measurement.

[0143] Next, the power supply amount estimation unit 114 calculates the power supply amount for each power source ID in the lower power source list 1413 from the record acquired in S1316 (S1317). If the power supply amount 1016 does not exist in the record acquired in S1315, the estimated supply amount lower bound 1022 is used instead for calculation. The calculation method is the same as in S1315.

[0144] Next, the power supply estimation unit 114 calculates an upper bound of the estimated supply amount based on differential measurement from the power supply amount in the upper measurement unit 1414 calculated in S1315 and the power supply amounts (or their estimated lower bounds) of other power sources in the lower power source list obtained in S1317 (S1318).

[0145] Specifically, the power supply amount is calculated by subtracting the total value of the power supply amount (or the estimated lower bound thereof) of the other power sources in the lower power source list calculated in S1317 from the power supply amount in the upper measurement unit 1414 calculated in S1315.

[0146] A specific example will be described with reference to FIG. 20. In the example of FIG. 20, the amount of power supply between the device Y0 and the power source X0 is estimated. First, in the differential measurement information acquired in S1313, the upper measurement unit is "Room A" and the lower power source list is "Power source X0, Power source X1". Next, in S1315, the amount of power supply of the upper measurement unit "Room A" is calculated, and 300 kWh is obtained here. In S1317, the lower limit of 100 kWh is acquired as the amount of power supply between the power source X1, which is the lower power source, and the connected device Y1. At this time, the amount of power supply of the upper measurement unit "Room A" is equal to the sum of the amounts of power supply of the power sources "X0" and "X1" in the lower power source list by definition, so the amount of power supply C1 of the power source X0 can be expressed as C1=300-C2 using the amount of power supply C2 of the power source X1. Since 100 kWh is obtained as the lower limit of the estimated amount of C2, it is found that C1≦200, and 200 kWh is obtained as the upper limit of the amount of power supply from the power source X0.

[0147] Returning to FIG. 17, the power supply amount estimating unit 114 then enters the power supply amount calculated in S1318 into the differential measurement estimated supply amount upper bound 1023 (S1319).

[0148] Next, the power supply amount estimating unit 114 enters the smaller value of the estimated supply amount upper bound 1021 and the differential measurement estimated supply amount upper bound 1023 into the final estimated supply amount 1024 (S1320).

[0149] If the difference measurement is not performed, the value of the estimated supply amount upper limit 1021 is entered.

[0150] In step S1320, the upper bound estimate of the power supply amount calculated individually in steps S1114 and S1116 is compared with the upper bound of the estimate based on the differential measurement calculated in step S1317, and the smaller estimate, that is, the estimate closer to the actual power supply amount, can be selected.

[0151] This completes the explanation of S519.

[0152] 21 is a flow chart for explaining the environmental value allocation process S1700. The support device 10 generates the environmental value allocation result 153 by executing the process S1700.

[0153] First, the environmental value allocation unit 115 acquires one target from the environmental value allocation target 152 (S1711). The steps from S1711 onwards are carried out for each target of the environmental value allocation target 152.

[0154] 22 is an example of the environmental value allocation target 152. An application start time 1811, an application end time 1812, an equipment ID 1813, a power source ID 1814, and a target renewable energy ratio 1818 are set.

[0155] If either the device ID 1813 or the power source ID 1814 is blank (-), this indicates that the setting is applied regardless of the device ID or power source ID.

[0156] 22, the target device or power source is individually specified by the device ID 1813 and the power source ID 1814, but other condition setting columns may be added to collectively specify multiple devices or power sources according to the owner or user of the device or power source. In this case, in the procedure described below, a determination is made as to whether or not the record corresponds to the target, and the device information list 122 or power source information list 132 is appropriately executed for that purpose.

[0157] Returning to FIG. 21, the environmental value allocation unit 115 acquires a record corresponding to the target acquired in S1711 from the power supply integrated log T1000 (S1712).

[0158] Whether or not it meets the target is determined based on application start time 1811, application end time 1812, device ID 1813, and power source ID 1814.

[0159] Next, the environmental value allocation unit 115 creates a row of the environmental value allocation result 153 from the acquired records of the power supply integrated log T1000 and the target (S1713). S1713 and subsequent steps are performed for each record of the acquired power supply integrated log T1000.

[0160] 23 is an example of the environmental value allocation result 153. In S1713, the application start time 1911, application end time 1912, device ID 1913, power source ID 1914, and renewable energy certification 1919 are transcribed from the items of the same name in the power supply integrated log T1000. In addition, the target renewable energy ratio 1925 is transcribed from the item of the same name in the environmental value allocation target 152.

[0161] As for the power supply amount 1915, if the power supply amount 1015 is entered in the power supply integrated log T1000, this is transcribed, and if it is unknown, the final estimated supply amount 1024 is transcribed.

[0162] In addition, the already allocated renewable energy ratio 1918 and the already allocated renewable energy manager 1920 transcribe the renewable energy ratio 1018 and the renewable energy manager 1020, respectively.

[0163] In S1713, if the start time 1011 and end time 1012 of the record acquired in S1712 overlap only a portion of the target application start time 1811 and application end time 1812, the application start time 1911 and application end time 1912 are corrected to match the overlapping time, and the power supply amount 1915 is multiplied by the proportion of the overlapping time.

[0164] Returning to FIG. 21, the environmental value allocation unit 115 then judges whether or not the record acquired in S1712 satisfies the target acquired in S1711 (S1714).

[0165] In determining whether the target is met, the target renewable energy ratio 1818 in the environmental value allocation target is compared with the already allocated renewable energy ratio 1918 in the generated environmental value allocation result 153 to determine whether the target is met.

[0166] Next, if the target is not met in S1714, the environmental value allocation unit 115 calculates a new renewable energy allocation ratio 1926 and a new renewable energy allocation amount 1927 in the environmental value allocation result 153 (S1715).

[0167] Here, the new renewable energy allocation ratio 1926 is calculated from the difference between the target renewable energy ratio 1818 in the target compared in S1714 and the already allocated renewable energy ratio 1918. Furthermore, the new renewable energy allocation amount 1927 is calculated by multiplying the power supply amount 1915 and the new renewable energy allocation ratio 1926 .

[0168] Next, the environmental value allocation unit 115 instructs the power procurement management server 4 to write off the corresponding environmental value based on the new renewable energy allocation amount 1927 calculated in S1715 (S1716). The power procurement management server 4 subtracts the new renewable energy allocation amount 1927 from the environmental value held in the environmental value held amount 141.

[0169] This concludes the explanation of the process S1700 of the environmental value allocation unit 115.

[0170] According to the above embodiment, for power supply carried out between devices and power sources, the power supply log generation process S500 estimates the amount of power supply for devices whose amount is unknown from the specifications of the device and power source and the power supplies of other devices and power sources, and also obtains the status of environmental value allocation by other parties, and the environmental value allocation process S1700 allocates a necessary and sufficient amount of environmental value based on the environmental value already allocated by other parties and the environmental value allocation target, thereby contributing to the promotion of corporate environmental efforts. EXAMPLES

[0171] In this embodiment, the process in the first embodiment is performed by a plurality of entities sharing the device side server 2 and the power supply side server 3.

[0172] In a case such as Example 2, rather than simply collecting information on environmental value allocations made by other entities and using it for one's own allocation as in Example 1, it is necessary to share one's own company's environmental value allocation information with other companies.

[0173] The second embodiment is basically the same as the first embodiment except for one point. That is, after the process in S1716 ends, the result of the allocation of the company is output in the form of the device side log 121 or the power source side log 131 in S1717.

[0174] According to the embodiment described above, information on power supply from the power receiving device, the power supplying power source, and other devices is collected, and missing information is estimated from the collected information, so that the composition of the supplied power can be determined. Furthermore, even if a power meter is not available, the power supply amount is estimated so that the required amount of renewable energy can be properly calculated. As a result, it is possible to provide an environmental value management support device and method that realizes environmental value management targeting a wide range of devices and power sources for power supply between devices and power sources, and enables environmental efforts to be shared among many stakeholders.

[0175] For example, in cases where a company's EV receives power from another company's power facility, if the other company's power source has already been assigned an environmental value, it is possible to avoid assigning duplicate environmental value to the company's EV. In this way, by integrating information on power sources, equipment, and other sources, the applied environmental value can be visualized without omissions or duplications, and certificates can be quickly allocated to any portion of the visualized environmental value that falls short of the target.
