However, the future value of a vehicle can fluctuate depending on the environment in which the vehicle is used and how the vehicle is used. In particular, in the case of battery-powered electric vehicles, the value can fluctuate significantly depending on the future condition of the battery.

[Overview of Information Processing System S]
1 is a diagram for explaining an overview of an information processing system S. The information processing system S is a system used for providing a user with information indicating the residual value of a vehicle V. The user is, for example, an employee of a leasing company that leases the vehicle V, or an employee of an insurance company that manages insurance (e.g., vehicle insurance) applicable to the vehicle V.

Vehicle V is an electric vehicle powered by battery B, such as a lithium-ion battery. Vehicle V also has various sensors (such as a current sensor for measuring the remaining charge of battery B and a brake pad sensor for detecting brake pad wear) and a communication unit for connecting to network N, and transmits information measured or detected by the various sensors to the outside via the communication unit.

The residual value of the vehicle V is the value of the vehicle V after the vehicle V has been used in a specified environment for a specified period of time. The residual value of the vehicle V is indicated, for example, by a monetary amount or a predetermined index. The specified environment of use includes the environment in which the vehicle V is used and the use of the vehicle V. The environment in which the vehicle V is used is, for example, a region, but is not limited thereto, and may be the temperature (for example, the number of days per year when the temperature exceeds the allowable range of the battery B), or the topography (for example, a plain, a mountainous area), etc. The use of the vehicle V is, for example, a general household use, a business use by a corporation, or a shuttle service by a corporation. The use of the vehicle V may be subdivided by mileage (for example, 5,000 km or less, 55,001 km to 10,000 km, etc.).

The information processing system S has an information processing device 1 and an information terminal 2. The information processing device 1 is a computer that outputs the residual value of a vehicle V. The vehicle V is provided with vehicle identification information for identifying the vehicle V, and the information processing device 1 manages the vehicle identification information for each of the multiple vehicles V.

The information terminal 2 is a terminal used by a user, and is a computer that displays information output by the information processing device 1. The information terminal 2 is, for example, a mobile terminal such as a smartphone or a tablet terminal, or a personal computer. The information terminal 2 has a display unit such as a liquid crystal display for displaying information.

An overview of the process by which the information processing device 1 outputs the residual value of the vehicle V1 is provided below. When a user inputs information to the information terminal 2, including vehicle identification information corresponding to the vehicle V1, information indicating the period of use during which the vehicle V1 will be used as a specified period, and information indicating the specified usage environment, for inquiring about the residual value of the vehicle V1, the information processing device 1 accepts the inquiry about the residual value of the vehicle V1 from the information terminal 2.

The residual value of vehicle V, which is an electric vehicle, depends heavily on the condition of the battery B installed on it. The condition of battery B used for a specified period of time can generally vary greatly depending on the usage environment, but by identifying the usage environment, the accuracy of estimating the condition of battery B after use can be improved. Thus, when the information processing device 1 receives the above inquiry, it identifies the condition of battery B of vehicle V1. From the identified condition of battery B, the information processing device 1 calculates the residual value of vehicle V1 based on the degree of deterioration of battery B when vehicle V1 is used in a specified usage environment. Then, the information processing device 1 outputs information to indicate the calculated residual value of vehicle V1.

In this way, the information processing system S can present to the user the future value of the vehicle V. This allows the information processing system S to reduce the difference between the calculated residual value of the vehicle V and the value of the vehicle after it has actually been used for a predetermined period of time in a predetermined environment. As a result, the information processing system S can improve the accuracy of calculating the future value of the vehicle.
The configuration of the information processing device 1 will be described below.

[Configuration of information processing device 1]
2 is a diagram showing the configuration of the information processing device 1. The information processing device 1 has a communication unit 11, a storage unit 12, and a control unit 13. The communication unit 11 is an interface for connecting to a network N, and is configured to include, for example, a LAN (Local Area Network) controller.

The memory unit 12 is a storage medium such as a ROM (Read Only Memory), a RAM (Random Access Memory), or a hard disk. The memory unit 12 stores a program executed by the control unit 13. The memory unit 12 stores information about the vehicle V. The information about the vehicle V includes, for example, vehicle identification information corresponding to the vehicle V, the maximum capacity of the battery B installed in the vehicle V, and the value of the vehicle V when new. The memory unit 12 also stores a calculation information database that manages information for calculating the residual value of the vehicle V, and an estimation information database that manages information for estimating the degree of deterioration of the battery B.

Figure 3 is a diagram showing an example of the configuration of a database stored in the storage unit 12. In the calculation information database shown in Figure 3 (a), the full charge capacity of battery B and the value of vehicle V at that full charge capacity are stored in association with each other. The full charge capacity stored in the calculation information database indicates the capacity rate relative to the maximum capacity of battery B. The value stored in the calculation information database indicates the residual value rate relative to the value of battery B when new.

The estimated information database shown in FIG. 3(b) stores the usage pattern (mileage, number of charges, etc.) of battery B in association with the decline rate. The decline rate stored in the estimated information database indicates, for example, the rate of decline in the full charge capacity of battery B when vehicle V is used in the associated usage pattern over a predetermined period (e.g., one year).

Returning to FIG. 2, the control unit 13 is, for example, a CPU (Central Processing Unit). The control unit 13 executes the programs stored in the storage unit 12, thereby functioning as a reception unit 131, a state identification unit 132, a calculation unit 133, a history information acquisition unit 134, and an output unit 135.

The reception unit 131 receives an inquiry about the residual value of the vehicle V, which includes vehicle identification information and is the value of the vehicle V after the vehicle V has been used in a specified environment for a specified period of time. Specifically, when a user inputs inquiry information to inquire about the residual value of a specific vehicle V, the information terminal 2 transmits the inquiry information to the information processing device 1. The inquiry information includes vehicle identification information, information indicating the specified period, and information indicating the specified environment of use. The specified period is, for example, a period specified by the user, such as six months, one year, or five years. The reception unit 131 then receives an inquiry about the residual value of the vehicle V by acquiring the inquiry information from the information terminal 2 via the communication unit 11. The information processing device 1 may have an operation unit (not shown) and may receive inquiry information input through the operation unit.

The state identification unit 132 identifies the state of the battery B mounted on the vehicle V identified by the vehicle identification information. The state of the battery B is, for example, the current full charge capacity (SOH: State of Health) of the battery B. The state identification unit 132 identifies the state of the battery B, for example, by acquiring information indicating the SOH from the vehicle V identified by the vehicle identification information.

The state identification unit 132 may acquire information for calculating the SOH from the vehicle V identified by the vehicle identification information, and calculate the SOH based on the acquired information. For example, the state identification unit 132 first acquires information from the vehicle V indicating the remaining capacity of battery B when it was last fully charged. Then, the state identification unit 132 calculates the SOH using the remaining capacity of battery B and the maximum capacity of battery B. The state identification unit 132 can calculate the SOH using known techniques.

The calculation unit 133 calculates the residual value of the vehicle V based on the degree of deterioration of the battery B when the vehicle V is used in a specified usage environment from the state of the battery B. Specifically, the calculation unit 133 first estimates the degree of deterioration of the battery B by estimating the state of the battery B at a second point in time after a specified period of time has passed based on the state of the battery B at a first point in time (present) identified by the state identification unit 132, a specified period of time, and a specified usage environment.

Then, the calculation unit 133 calculates the residual value of the vehicle V based on the estimated degree of deterioration of the battery B. For example, the calculation unit 133 calculates the residual value of the vehicle V by multiplying the value of the vehicle V when it was new by a numerical value indicated by the value stored in the calculation information database in association with the estimated state (full charge capacity) of the battery B at the second point in time.

For example, the memory unit 12 stores the rate of decline (e.g., annual rate of decline) of the full charge capacity of battery B determined for each usage environment (e.g., for each combination of the environment in which vehicle V is used and the use of vehicle V). In this case, the calculation unit 133 calculates the degree of deterioration of battery B by calculating the full charge capacity of battery B at a second time point by subtracting a multiplied value obtained by multiplying the decline rate stored in memory unit 12 in association with the specified usage environment accepted by the acceptance unit 131 and a numerical value corresponding to a specified period from the full charge capacity (capacity rate relative to maximum capacity) of battery B at a first time point. The numerical value corresponding to the specified period is, for example, "3" if the specified period is three years.

The calculation unit 133 may estimate the degree of deterioration of battery B based on the usage pattern of battery B as the specified usage environment. Specifically, first, the reception unit 131 receives an inquiry from a user that further includes information indicating the usage pattern of battery B, such as the mileage and the number of charges. Then, the calculation unit 133 estimates the degree of deterioration of battery B by calculating the full charge capacity of battery B at a second time point by subtracting a multiplied value obtained by multiplying a decline rate stored in the estimated information database in association with the above usage pattern and a numerical value corresponding to a specified period from the full charge capacity of battery B at a first time point. In this way, the information processing device 1 can improve the accuracy of estimating the degree of deterioration of battery B.

The calculation unit 133 may estimate the degree of deterioration of the battery B using historical information of a user who uses the vehicle V in a specified usage environment for a specified period of time as information indicating the specified usage environment. The user may be an individual or a corporation.

The history information is information that indicates the usage history of the vehicle by the user, and is information for indicating a specified usage environment. The history information includes, for example, the mileage for each day, month, or year (mileage on ordinary roads, mileage on expressways, mileage during the day, mileage at night, etc.), the number of discharge and charge cycles, the electrical load time (for example, the time the air conditioner is used, etc.), the number of normal charges, and the number of quick charges (hereinafter referred to as "mileage, etc."). The vehicle in use is an electric vehicle different from vehicle V. The vehicle in use may be vehicle V managed by the information processing device 1, or it may be a vehicle not managed by the information processing device 1.

Specifically, first, the reception unit 131 receives an inquiry that further includes user identification information for identifying the user. The history information acquisition unit 134 acquires the user's history information based on the user identification information. For example, the user identification information and history information are stored in association with each other in the memory unit 12, and the history information acquisition unit 134 acquires the history information stored in the memory unit 12 in association with the user identification information.

A management device (not shown) managed by the manufacturer of the vehicle in use manages the user identification information in association with the history information of the vehicle in use, and the history information acquisition unit 134 may acquire the history information managed in association with the user identification information from the management device via the communication unit 11. If the user is a corporation, the history information acquisition unit 134 may acquire the history information via the communication unit 11 from a management ledger system (not shown) in which the corporation manages the use of the vehicle.

Then, the calculation unit 133 estimates the degree of deterioration of battery B based on the usage pattern of battery B based on the history information acquired by the history information acquisition unit 134. The calculation unit 133 identifies the usage pattern of battery B based on the history information, and estimates the degree of deterioration of battery B based on the identified usage pattern of battery B.

For example, first, the calculation unit 133 calculates the average mileage, etc. by averaging the mileage, etc., of each year included in the history information. Then, the calculation unit 133 estimates the degree of deterioration of battery B by calculating the full charge capacity of battery B at a second point in time by subtracting the product obtained by multiplying the deterioration rate stored in the estimated information database in association with the usage pattern corresponding to the calculated average mileage, etc., by a numerical value corresponding to a predetermined period of time from the full charge capacity of battery B at a first point in time.

The calculation unit 133 may estimate the degree of deterioration of the battery B using a predetermined machine learning model. The predetermined machine learning model is a machine learning model trained using training data including the period during which the vehicle V was used, the full charge capacity of the battery B before the period, the full charge capacity of the battery B after the period, and history information indicating the usage history during the period.

The calculation unit 133 inputs information indicating the full charge capacity of battery B at a first point in time, information indicating a predetermined period of time, and user history information into a predetermined machine learning model, and estimates the degree of deterioration of battery B by obtaining information indicating the full charge capacity of battery B at a second point in time output by the predetermined machine learning model. In this way, the information processing device 1 can improve the accuracy of estimating the degree of deterioration of battery B by estimating the degree of deterioration of battery B using the user's history information.

The calculation unit 133 may update the information for estimating the degree of deterioration of battery B. Specifically, first, the state identification unit 132 identifies the state of vehicle V at a first point in time before a predetermined period of time, and identifies the state of vehicle V at a second point in time after the predetermined period of time has elapsed. Then, the calculation unit 133 updates the information for estimating the degree of deterioration of battery B based on the difference between the degree of deterioration of battery B estimated based on the state of vehicle V at the first point in time and the degree of deterioration of battery B indicated by the state of vehicle V at the second point in time.

The information for estimating the degree of deterioration of battery B is, for example, information stored in an estimation information database or parameters set in a predetermined machine learning model. The calculation unit 133 updates the information for estimating the degree of deterioration of battery B when, for example, the difference between the full charge capacity estimated based on the state of vehicle V at a first time point (hereinafter referred to as the "first full charge capacity") and the full charge capacity indicated by the state of vehicle V at a second time point (hereinafter referred to as the "second full charge capacity") exceeds a predetermined threshold value.

Figure 4 is a diagram showing a schematic representation of the state of battery B. Position G1 shown in Figure 4 indicates the degree of deterioration of battery B estimated by the calculation unit 133 based on the state of vehicle V at a first point in time. Position G2 shown in Figure 4 indicates the state of vehicle V at a second point in time identified by the state identification unit 132. In the example shown in Figure 4, the second full charge capacity is less than the first full charge capacity, and the difference exceeds a threshold value. In this case, the calculation unit 133 updates the information used to estimate the first full charge capacity so that the rate of decrease in the range from position G1 to position G2 is smaller than that of position G1. In this way, the information processing device 1 can improve the accuracy of estimating the degree of deterioration of battery B.

The calculation unit 133 may calculate the residual value of the vehicle V based on the degree of deterioration of components other than the battery B, in addition to the degree of deterioration of the battery B. The components are parts that make up the vehicle V, such as the body, drive unit (motor), chassis, consumable parts (e.g., brake pads, headlights, etc.), etc.

Specifically, first, the condition identification unit 132 further identifies the condition of components other than the battery B. The condition identification unit 132 may identify the condition of the components based on information measured by various sensors of the vehicle V, or may identify the condition of the components by acquiring information indicating the condition of the components managed by the manufacturer's management device. Then, the calculation unit 133 calculates the residual value of the vehicle V based on the degree of deterioration of the components when the vehicle V is used in a specified usage environment from the condition of the components, in addition to the degree of deterioration of the battery B.

For example, the memory unit 12 stores the deterioration rate of each component indicating the degree of deterioration of each component for each usage environment, and the calculation unit 133 estimates the degree of deterioration of battery B based on the rate of decline in the full charge capacity of battery B, and estimates the degree of deterioration of each component based on the deterioration rate of each component stored in the memory unit 12 in association with a specified usage environment. The calculation unit 133 then calculates the residual value of vehicle V based on the estimated degree of deterioration of battery B and the degree of deterioration of each component. In this way, the information processing device 1 can improve the accuracy of calculating the residual value of vehicle V.

The output unit 135 outputs information indicating the residual value of the vehicle V calculated by the calculation unit 133. The output unit 135 transmits the information indicating the residual value of the vehicle V calculated by the calculation unit 133 to the information terminal 2, for example, via the communication unit 11.

The output unit 135 may output various information in addition to information indicating the residual value of the vehicle V. For example, the output unit 135 may output calculation information for calculating the lease price of the vehicle V when the vehicle V is used in a specified usage environment for a specified period of time. The specified period in this case is the planned lease period specified by the user. For example, the storage unit 12 stores, for each vehicle V, the used period during which the vehicle V was used, the used environment in which the vehicle V was used, and the subtraction value in association with each other. The subtraction value is the value of the vehicle V at the start of the used period minus the value of the vehicle V at the end of the used period.

In this case, first, the reception unit 131 receives an inquiry for calculation information including information indicating the planned lease period and information indicating the specified usage environment. The calculation unit 133 calculates the statistical value of the subtraction value of each vehicle V stored in the storage unit 12 in association with the used period corresponding to the planned lease period and the used environment corresponding to the specified usage environment. The used period corresponding to the planned lease period is, for example, a used period of a period equal to the planned lease period, or a used period of a period close to the planned lease period. The used environment corresponding to the specified usage environment is, for example, a used environment in which the area in which the vehicle V is used and the use of the vehicle V match, or a used environment in which the area in which the vehicle V is used and the use of the vehicle V are close. The statistical value is, for example, an average value, a median, a mode, or the like.

Then, the output unit 135 outputs the statistical value calculated by the calculation unit 133 as calculated information. In this way, the user (an employee of the leasing company) can understand the statistical value that will be consumed if the product is used in a specified usage environment during the lease period.

For example, the output unit 135 may output calculation information for calculating the price of vehicle insurance for the vehicle V to be applied for a specified period. The specified period in this case is the planned contract period specified by the user. For example, the memory unit 12 stores, for each vehicle V, the contract period of the vehicle insurance for which the vehicle V has been subscribed, the environment in which the vehicle V was used during the contract period of the vehicle insurance, the number of times the vehicle V has been repaired using the vehicle insurance, and the value of the vehicle V when the contract period of the vehicle insurance expires, in association with each other.

In this case, first, the reception unit 131 receives an inquiry for calculation information including information indicating the planned contract period and information indicating the specified usage environment. The calculation unit 133 calculates the statistical value of the number of uses of each vehicle V stored in the memory unit 12 in association with the vehicle insurance contract period corresponding to the planned contract period, the used environment corresponding to the specified usage environment, and the value of the vehicle V corresponding to the calculated residual value of the vehicle V. The vehicle insurance contract period corresponding to the planned contract period is, for example, a contract period equal to the planned contract period, or a contract period close to the planned contract period. The value of the vehicle V corresponding to the residual value of the vehicle V is, for example, a value of the vehicle V that matches the residual value of the vehicle V, or a value of the vehicle V that is close to the residual value of the vehicle V.

Then, the output unit 135 outputs the statistical value as calculated information. In this way, the user (employee of the insurance company) can grasp the statistical number of times the vehicle insurance will be used when used in a specified usage environment during the contract period.

[Processing of Information Processing System S]
Next, a description will be given of the flow of processing in the information processing system S. Fig. 5 is a sequence diagram showing the flow of the information processing system S. This processing starts when the information terminal 2 transmits inquiry information input by a user to the information processing device 1 (S1).

When the reception unit 131 acquires the inquiry information, the condition determination unit 132 determines the condition of the battery B installed in the vehicle V identified by the vehicle identification information included in the inquiry information (S2). The calculation unit 133 estimates the degree of deterioration of the battery B by estimating the condition of the battery B at a second time point after a predetermined period of time has passed based on the condition of the battery B at a first time point determined by the condition determination unit 132, a predetermined period of time, and a predetermined usage environment (S3).

The calculation unit 133 calculates the residual value of the vehicle V based on the estimated degree of deterioration of the battery B (S4). Then, the output unit 135 transmits information indicating the residual value of the vehicle V calculated by the calculation unit 133 to the information terminal 2 via the communication unit 11 (S5).
