Now, as a measure to prevent global warming, which is currently a problem, it is urgent to promote the use of power generation using natural energy such as power generation by the solar power generation device 23, and for this purpose, it is necessary to promote power generation by the solar power generation device 23 mounted on the vehicle 5, i.e., solar power generation using the vehicle 5. In this case, as an effective method for increasing interest in power generation by the solar power generation device 23 mounted on the vehicle 5, it is considered to be possible to build a system that matches those who wish to provide natural energy utilization information related to the power generation or use of electric energy generated by the solar power generation device 23 mounted on the vehicle 5 with those who wish to obtain this natural energy utilization information, and it is considered that the construction of such a matching system can promote solar power generation using vehicles.

Therefore, in an embodiment of the present invention, a system is constructed that matches those who wish to provide natural energy utilization information related to the generation or use of electric energy generated by the solar power generation device 23 mounted on the vehicle 5 with those who wish to obtain this natural energy utilization information. In this case, matching between those who wish to provide natural energy utilization information and those who wish to obtain this natural energy utilization information can be performed by direct communication between the providers and those who wish to obtain this information, or it can be performed in the management server 3. Below, the present invention will be described using the example of performing this matching in the management server 3.

When matching is performed in this manner in the management server 3, a matching processing site is provided in the management server 3, and the natural energy usage information desired to be provided provided by those who wish to provide and the natural energy usage information desired to be acquired presented by those who wish to acquire are aggregated on this matching processing site. In this case, in an embodiment of the present invention, a list of natural energy usage information desired to be provided as shown in FIG. 5 and a list of natural energy usage information desired to be acquired as shown in FIG. 6 are created on the matching processing site. This matching processing site can be accessed by those who wish to provide natural energy usage information and those who wish to acquire natural energy usage information. Next, these lists of natural energy usage information will be explained.

First, referring to Fig. 5, the list of desired natural energy use information shown in Fig. 5 lists the willing provider, the desired natural energy use information, and the desired supply conditions for each vehicle 5 indicated by No. 1, No. 2, No. 3, .... In this case, the willing provider is the owner of the vehicle 5, etc. Meanwhile, in the example shown in Fig. 5, the desired natural energy use information lists the amount of power generated by the solar power generation device 23, the charge amount of the battery 22, and the consumption amount of electric energy used to drive the vehicle 5. Furthermore, in the example shown in Fig. 5, in addition to the amount of power generated, the charge amount, and the consumption amount, the amount of _CO2 emission reduction is also listed.

In this case, in the embodiment of the present invention, the amount of _CO2 emissions reduced when the vehicle 5 is driven using the electric motor 20 instead of the internal combustion engine is regarded as the amount of _CO2 emissions reduction, and this amount of _CO2 emissions reduction is calculated from the consumption amount of electric energy used to drive the vehicle 5, etc. In this case, the owner of the vehicle 5 is granted the right to emit an amount of _CO2 equivalent to this amount of _CO2 emissions reduction as a tradable carbon credit. That is, in the example shown in FIG. 5, information on the amount of _CO2 emissions reduction that is the subject of trading by carbon credit is also listed. In addition, in the list shown in FIG. 5, the desired provision conditions present monetary requests, points, and other acquisition requests in return for providing natural energy utilization information.

Note that each value shown in the renewable energy provision information in Fig. 5 indicates a value at a certain time every fixed time, for example, every 10 minutes, every hour, or every day. Furthermore, when each value shown in the table in Fig. 5 indicates a value at a certain time every day, each value may indicate a total value for the past day up to that time, or each value may indicate a total value of all past values up to that time. In this case, when each value shown in the renewable energy provision information in Fig. 5 indicates a total value for the past day at a certain time, the amount of power generation, amount of charge, amount of consumption, and amount of _CO2 emission reduction in Fig. 5 indicate a total value for the past day at a certain time.

Next, referring to FIG. 6, the list of desired natural energy use information shown in FIG. 6 lists the acquirer, the desired natural energy use information, and the desired acquisition conditions for each vehicle 5 indicated by No. 1, No. 2, No. 3, etc. In this case, the acquirer is a company, research institute, or individual who wishes to acquire natural energy use information, as described above. On the other hand, as shown in FIG. 6 , the desired natural energy use information is part or all of the desired natural energy use information consisting of the amount of power generated by the solar power generation device 23, the charged amount of the battery 22, the consumption of electric energy used to drive the vehicle 5, and the amount of _CO2 emission reduction. Note that _At1 , _Bt1 , _Ct1 , _Dt1 , and _Dt5 in parentheses in the desired natural energy use information column represent the desired amount to be acquired.

6, the desired acquisition conditions include monetary compensation, points, and other compensation in return for acquiring natural energy utilization information. If the acquirer wishes to acquire the right to emit _CO2 , the acquirer presents an acquisition request for a part or all of the _CO2 emission reduction amount that can be provided presented by the provider, and if the provider accepts the presented acquisition request, the acquirer can acquire the right to emit an amount of _CO2 equivalent to the desired _CO2 emission reduction amount as carbon credits.

Next, an example of a method for creating the natural energy utilization information to be provided in the list shown in FIG. 5 will be described with reference to FIG. 7 to FIG. 9. FIG. 7 shows a procedure for advance registration performed in the management server 3. Referring to FIG. 7, as shown by A1 in FIG. 7, first, on the display screen of the display unit 34 of the vehicle 5, a list creation site of the natural energy utilization information of the management server 3 is accessed, and information about the vehicle body, such as the model number of the vehicle, is registered in the list creation site of the management server 3. Next, as shown by A2 in FIG. 7 , information about the owner's name of the vehicle 5, etc. is registered on the display screen of the display unit 34 of the vehicle 5. The registered information is stored in the memory 13 of the electronic control unit 10 of the management server 3. When the registration of the information about the owner's name of the vehicle 5, etc. is completed, a vehicle ID is assigned to the vehicle 5 in the management server 3 , as shown by A3 in FIG. 7 , and the assigned vehicle ID is transmitted to the vehicle 5 and stored in the memory 28 of the electronic control unit 25 of the vehicle 5.

8 shows a basic information transmission routine for transmitting basic information for calculating the desired natural energy utilization information from the vehicle 5 to the management server 3. When the use of the vehicle 5 is started, this routine is executed in the electronic control unit 25 of the vehicle 5 by an interrupt at regular time intervals, for example, every second.
Referring to FIG. 8, first, in step 50, the power generation current Ia and the power generation voltage Va of the solar power generation device 23 are detected. Next, in step 51, the power generation power Pa (kW) of the solar power generation device 23 is calculated from the detected power generation current Ia and power generation voltage Va. Next, in step 52, the terminal voltage Vb and the temperature Tb of the battery 22 are detected. Next, in step 53, the drive current Ic and the drive voltage Vc of the electric motor 20 are detected. Next, in step 54, the drive power Pc of the electric motor 20 is calculated from the detected drive current Ic and drive voltage Vc. Next, in step 55, each data, i.e., the calculated power generation power Pa of the solar power generation device 23, the detected terminal voltage Vb and temperature Tb of the battery 22, and the calculated drive power Pc of the electric motor 20 are transmitted to the management server 3 together with the vehicle ID, and the transmitted data are stored in the memory 13 of the electronic control unit 10 of the management server 3.

9 shows a routine for calculating the renewable energy utilization information to be provided. This routine is repeatedly executed in the electronic control unit 10 of the management server 3.
9, first, in step 60, it is determined whether or not basic information transmitted from the vehicle 5 has been received. If it is determined that the basic information has been received, the process proceeds to step 61, where the power generation electric power Pa of the photovoltaic power generation device 23 is integrated, and the integrated value of the power generation electric power Pa is set to ΣPa. Furthermore, based on this integrated value ΣPa of the power generation electric power Pa, the power generation amount (kwh) of the photovoltaic power generation device 23 within a certain time (e.g., one hour or one day) from the start of integration is calculated. Next, in step 62, the current charge amount Q of the battery 22 is calculated based on the terminal voltage Vb and temperature Tb of the battery 22.

Next, in step 63, the driving power Pc of the electric motor 20 is integrated, and the integrated value of the driving power Pc of the electric motor 20 is set as ΣPc. In addition, based on the integrated value ΣPc of the driving power Pc of the electric motor 20, the consumption amount (kwh) of electric energy within a certain time (e.g., one hour or one day) from the start of the integration is calculated. Meanwhile, as described above, in the embodiment according to the present invention, the amount of _CO2 emissions reduced when the vehicle 5 is driven using the electric motor 20 instead of the internal combustion engine is set as the _CO2 emission reduction amount, and this _CO2 emission reduction amount is calculated from the consumption amount of electric energy used to drive the vehicle 5. Therefore, in step 64, based on the integrated value ΣPc of the driving power Pc of the electric motor 20 calculated in step 73, the _CO2 emission reduction amount R within a certain time (e.g., one hour or one day) from the start of the integration is calculated. In this way, the column of the provider applicant and the column of the desired natural energy utilization information in the table shown in FIG. 5 are created.

Figure 10 shows the procedure for registering desired supply conditions and the like to the management server 3, which is carried out in the vehicle 5. Referring to Figure 10, as shown in C1 of Figure 10, for example, the owner of the vehicle 5 accesses the management server 3's site for creating a list of desired natural energy use information on the display screen of the display unit 34 of the vehicle 5, and inputs the name of the person who wishes to provide, for example the name of the owner of the vehicle 5, and the desired supply conditions to the management server 3's site for creating a list of desired natural energy use information. Once input of this data is completed, in C2 of Figure 10, the input data and the vehicle ID are sent to the management server 3, and the person who wishes to provide and the desired supply conditions are registered in the list of desired natural energy use information shown in Figure 6.

Figure 11 shows the procedure for registering the desired acquisition information, etc., in the management server 3 using the communication device 40 (Figure 4) installed in the desired acquisition company 4. Referring to Figure 11, as shown in D1 of Figure 11, for example, the desired acquisition person accesses the management server 3's list creation site for the desired acquisition of natural energy usage information using the communication device 40 (Figure 4) installed in the desired acquisition company 4, and inputs the desired acquisition name, the desired natural energy usage information to be provided, and the desired acquisition conditions to the list creation site for the desired acquisition of natural energy usage information in the management server 3. When the input of this data is completed, in D2 of Figure 11, this input data is sent to the management server 3, and the desired acquisition name, the desired natural energy usage information to be provided, and the desired acquisition conditions are registered in the list of the desired acquisition of natural energy usage information shown in Figure 6.

Figure 12 shows a matching process routine for matching a provider with a buyer. This routine is executed in the electronic control unit 10 of the management server 3 at regular intervals, for example, every 10 minutes, every hour, or every 24 hours. Below, this matching process routine will be explained using as an example a case where a provider and a buyer are matched based on the list of renewable energy use information desired to be provided shown in Figure 5 and the list of renewable energy use information desired to be acquired shown in Figure 6.

Referring to FIG. 12, first, in step 100, the desired natural energy usage information No. 1 in the list of desired natural energy usage information shown in FIG. 6 is read. Next, in step 101, information that satisfies the read desired natural energy usage information No. 1 is extracted from the list of available desired natural energy usage information shown in FIG. 5, and the number of the extracted available natural energy usage information is stored. Next, in step 102, the available natural energy usage information with the first extracted number from the extracted available natural energy usage information is read.

Next, in step 103, it is determined whether the desired supply conditions of the available natural energy utilization information of the first extracted number match the desired acquisition conditions of the desired natural energy utilization information of No. 1. If it is determined that the desired supply conditions match the desired acquisition conditions, the process proceeds to step 104, where both the acquirer and the supplier, or at least one of them, are notified that the transaction has been concluded. On the other hand, if it is determined that the desired supply conditions do not match the desired acquisition conditions, the process proceeds to step 105, where it is determined whether the determination of whether the desired supply conditions match the desired acquisition conditions for all extracted numbered available natural energy utilization information has been completed.

When it is determined that the condition match determination between the desired provision conditions and the desired acquisition conditions has not been completed for all of the extracted available natural energy utilization information of the number No., the process proceeds to step 106, where the extracted available natural energy utilization information of the next number No. is read. Next, the process proceeds to step 103, where it is determined whether the desired provision conditions of the extracted available natural energy utilization information of the next number No. match the desired acquisition conditions of the desired acquisition of natural energy utilization information No. 1. When it is determined in step 105 that the condition match determination between the desired provision conditions and the desired acquisition conditions has been completed for all of the extracted available natural energy utilization information of the number No., the process proceeds to step 107.

In step 107, it is determined whether or not such condition matching determination has been completed for all of the desired natural energy use information numbers listed in the list of desired natural energy use information shown in FIG. 6. If it is determined that such condition matching determination has not been completed for all of the desired natural energy use information numbers, the process proceeds to step 108, where the next desired natural energy use information number in the list of desired natural energy use information shown in FIG. 6 is read. Then, the process proceeds to step 101. In this way, it is determined whether or not the desired provision conditions and the desired acquisition conditions match for all of the desired natural energy use information in the list of desired natural energy use information shown in FIG. 6.

Note that the example shown in FIG. 12 only describes the case where the desired provision conditions and the desired acquisition conditions match, but it is of course possible to construct a matching system that allows the acquirer and the provider to negotiate when the desired provision conditions and the desired acquisition conditions do not match.

In this manner, in the embodiment of the present invention, a matching processing unit is provided that acquires natural energy utilization information related to the generation or use of electric power energy generated by the solar power generation device 23 mounted on the vehicle 5, and matches a person who wishes to provide the acquired natural energy utilization information with a person who wishes to acquire the natural energy utilization information. In this case, in the embodiment of the present invention, the electronic control unit 10 of the management server 3 constitutes this matching processing unit.
In addition, in an embodiment of the present invention, an energy utilization information processing method is provided that acquires natural energy utilization information regarding the generation or use of electric power energy generated by a solar power generation device 23 mounted on a vehicle 5, and matches a person wishing to provide the acquired natural energy utilization information with a person wishing to acquire the natural energy utilization information.
In addition, in an embodiment of the present invention, a program is provided that causes a computer to acquire natural energy utilization information regarding the generation or use of electric power energy generated by a solar power generation device 23 mounted on a vehicle 5, and to match a person wishing to provide the acquired natural energy utilization information with a person wishing to acquire the natural energy utilization information.

Moreover, in an embodiment of the present invention, the natural energy utilization information includes information on the amount of power generated by the solar power generation device 23. Moreover, in an embodiment of the present invention, the natural energy utilization information includes, in addition to information on the amount of power generated, at least one of information on the charge amount of the battery 22 mounted on the vehicle 5 and information on the amount of power consumed to drive the vehicle 5. Moreover, in an embodiment of the present invention, the natural energy utilization information includes information on the amount of _CO2 emission reduction that is the subject of trading by carbon credits, and the matching processing unit matches carbon credit acquirers with people who wish to purchase carbon credits.

In addition, in an embodiment of the present invention, the desired acquisition information of natural energy is presented by the potential acquirer, and the matching processing unit determines whether the desired acquisition information of the potential acquirer is included in the desired provision information of natural energy provided by the potential provider, and matches the potential acquirer with the desired provider when it is determined that the desired acquisition information of the potential acquirer is included in the desired provision information of natural energy provided by the potential provider. In this case, in an embodiment of the present invention, when the matching processing unit matches the potential acquirer with the desired provider, it notifies at least one of the potential acquirer and the desired provider that a transaction has been established.

In this way, by constructing a system that matches those who wish to provide natural energy usage information regarding the generation or use of electric energy generated by the solar power generation device 23 mounted on the vehicle 5 with those who wish to obtain this natural energy usage information, it is possible to increase interest in power generation by the solar power generation device 23 mounted on the vehicle 5, thereby promoting solar power generation using vehicles. Therefore, it can be said that the present invention contributes to a decarbonized, carbon neutral, and sustainable society (SDGs) by promoting the use of natural energy, including sunlight.

Next, we will explain an embodiment in which, when a provider determines that they can provide the desired natural energy usage information based on the desired natural energy usage information registered on the management server 3's list creation site for the desired natural energy usage information, the provider makes an offer to provide the desired natural energy usage information to the acquirer.

Figure 13 shows an example of a procedure for matching a provider with a buyer in such a case. Referring to Figure 13, in this example, based on the desired natural energy use information registered in the desired natural energy use information list creation site of the management server 3, the provider who has determined that they can provide the desired natural energy use information of the buyer in E1 of Figure 13 sends a statement to the management server 3 that they can provide the desired natural energy use information together with the desired acquisition conditions, that is, an offer to provide, on the display screen of the display unit 34 of the vehicle 5 or via the mobile terminal 6 owned by the owner of the vehicle 5. When the management server 3 receives the offer to provide, in E2 of Figure 13, the management server 3 performs a matching process between the provider and the buyer using a matching process routine as shown in Figure 12.

Figure 14 shows another example of a procedure for matching a provider and a buyer. Referring to Figure 14, in this example, first, in F1 of Figure 14, the desired natural energy use information registered in the management server 3's list creation site for desired natural energy use information is transmitted from the management server 3 to the vehicle 5 or the mobile terminal 6 owned by the owner of the vehicle 5, and these data are displayed on the display screen of the display unit 34 of the vehicle 5 or on the mobile terminal 6. In F2 of Figure 14, a provider who has determined that they can provide the displayed desired natural energy use information transmits a statement that they can provide the desired natural energy use information together with the desired acquisition conditions, that is, an offer to provide, to the management server 3. When the management server 3 receives the offer to provide, in F3 of Figure 14, the management server 3 performs a matching process between the provider and the buyer using a matching process routine as shown in Figure 12.

Figure 15 shows yet another example of a procedure for matching a provider with a buyer. This example shows a case where a matching process is performed between a provider and a buyer for available natural energy usage information that the provider plans to acquire. Referring to Figure 15, in this example, in G1 of Figure 15, the provider accesses the management server 3's list creation site for natural energy usage information on the display screen of the display unit 34 of the vehicle 5, and inputs the available natural energy usage information that the provider plans to acquire and the desired supply conditions. After completing the input of this data, in G2 of Figure 15, this data is transmitted to the management server 3. Thereafter, in G3 of Figure 15, the management server 3 performs a matching process between the provider and the buyer using a matching process routine as shown in Figure 12.
