     DESCRIPTION OF EMBODIMENTS 
     Hereinafter, embodiments of an information processing device, an information processing method, and a program of the present invention will be described with reference to the drawings. Although a vehicle is assumed to be an electric vehicle in the following description, the vehicle may be a hybrid vehicle or a fuel cell vehicle as long as it is a vehicle equipped with a secondary battery that supplies electric power for traveling of the vehicle. 
       FIG. 1  is a diagram showing an example of a configuration of an information processing system  1  according to the embodiment. The information processing system  1  includes one or more vehicles  100 , one or more secondary-use-related user terminals  200 , and an information processing device  300 . The vehicles  100 , the secondary-use-related user terminals  200 , and the information processing device  300  communicate with other devices via a network NW. The network NW includes, for example, the Internet, a wide area network (WAN), a local area network (LAN), a provider device, a radio base station, and the like. In the information processing system  1 , the information processing device  300  manages product information of a battery (a storage battery) mounted in the vehicle  100  and information about a use state thereof or the like (hereinafter referred to as battery data) and provides various types of information about the battery to the vehicle  100 , the secondary-use-related user terminal  200 , and the like. The secondary-use-related user terminal  200  is a terminal device used by a user who secondarily uses the battery  140 . The secondary-use-related user includes, for example, a user who reuses a battery used in another vehicle by mounting the battery in his/her own vehicle, a seller who sells a used vehicle equipped with a battery that has been mounted in the vehicle  100  or sells the battery that has been mounted in the vehicle  100  as a battery (a used battery) for secondary use, a user who uses the battery  140  as a stationary battery in a facility such as a factory, or the like. The secondary-use-related user terminal  200  may be a terminal device installed at a prescribed position or may be a portable terminal device (for example, a portable terminal) such as a smartphone or a tablet terminal. Hereinafter, the functions of the vehicle  100 , the secondary-use-related user terminal  200 , and the information processing device  300  will be specifically described. 
     Vehicle  100   
       FIG. 2  is a diagram showing an example of a configuration of the vehicle  100 . As shown in  FIG. 2 , the vehicle  100  includes, for example, a motor  112 , drive wheels  114 , a brake device  116 , a vehicle sensor  120 , a power control unit (PCU)  130 , a battery (a storage battery)  140 , a battery sensor  142 , a data generation device  150 , a communication device  160 , a charging port  170 , a converter  172 , and a display device  180 . 
     The motor  112  is, for example, a three-phase AC motor. The rotor of the motor  112  is connected to the drive wheels  114 . The motor  112  outputs motive power to the drive wheels  114  using, for example, the electric power supplied from the battery  140 . Also, the motor  112  may generate electric power using kinetic energy of the vehicle when the vehicle is decelerated. 
     The brake device  116  includes, for example, a brake caliper, a cylinder that transfers hydraulic pressure to the brake caliper, and an electric motor that generates hydraulic pressure in the cylinder. The brake device  116  may include a mechanism that transfers hydraulic pressure generated by the operation of the brake pedal to the cylinder via a master cylinder as a backup. Also, the brake device  116  is not limited to the above-described configuration and may be an electronically controlled hydraulic brake device that transfers the hydraulic pressure of the master cylinder to the cylinder. 
     For example, the vehicle sensor  120  includes an accelerator opening degree sensor, a vehicle speed sensor, and a brake depression amount sensor. The accelerator opening degree sensor is attached to an accelerator pedal, which is an example of an operation element for receiving an acceleration instruction from a driver, detects an amount of operation of the accelerator pedal, and outputs the detected amount of operation as an accelerator opening degree to the controller  136 . The vehicle speed sensor includes, for example, a wheel speed sensor and a speed calculator attached to each wheel and combines wheel speeds detected by wheel speed sensors to derive the speed of the vehicle (a vehicle speed) and outputs the derived speed to the controller  136  and the display device  180 . The brake depression amount sensor is attached to the brake pedal, detects the amount of operation of the brake pedal, and outputs the detected amount of operation as an amount of brake depression to the controller  136 . Also, the vehicle sensor  120  may include, for example, a yaw rate sensor that detects an angular velocity around the vertical axis of the vehicle  100  and a direction sensor that detects the direction of the vehicle  100 . 
     The PCU  130  includes, for example, a converter  132 , a voltage control unit (VCU)  134 , and the controller  136 . Also, a group of the above components is configured as the PCU  130  as only an example and these components may be arranged in a distributed form. 
     The converter  132  is, for example, an alternating current (AC)-direct current (DC) converter. A DC side terminal of the converter  132  is connected to a DC link DL. The battery  140  is connected to the DC link DL via the VCU  134 . The converter  132  converts an AC generated by the motor  12  into a DC and outputs the DC to the DC link DL. 
     The VCU  134  controls the charging and discharging of the battery on the basis of control information from the controller  136 . The VCU  134  performs discharging control for outputting the electric power supplied from the battery  140  to the DC link DL according to the control of the controller  136 . Also, the VCU  134  adjusts a voltage of the DC link DL on the basis of the control information from the battery/VCU controller and controls the charging of the battery  140  so that a prescribed SOC is provided. 
     The controller  136  includes, for example, a motor controller, a brake controller, and a battery/VCU controller. The motor controller, the brake controller, and the battery/VCU controller may be replaced with separate control devices (for example, control devices such as a motor ECU, a brake ECU, and a battery ECU). 
     The motor controller controls the motor  112  on the basis of an output of the vehicle sensor  120 . The brake controller controls the brake device  116  on the basis of the output of the vehicle sensor  120 . The battery/VCU controller derives a state of charge (SOC) on the basis of an output (for example, a voltage value, a current value, or a temperature) of the battery sensor  142  attached to the battery  140 . 
     Specifically, the battery/VCU controller acquires the remaining capacity of energy with which the battery  140  is charged (hereinafter simply referred to as “remaining capacity”) on the basis of a magnitude of a voltage value of the battery  140 . Also, the battery/VCU controller may acquire the remaining capacity by integrating amounts of electric current stored in the battery  140  at the time of charging and obtaining an amount of electric current output at the time of discharging. Also, the battery/VCU controller may pre-store a database of discharging characteristics and temperature characteristics of the battery  140  in a storage (not shown) or the like, collate a voltage value, a current value, and a temperature measured from the battery sensor  142  with identical items in the database, and acquire the remaining capacity associated with the voltage value, the current value, and the temperature. Also, the battery/VCU controller acquires a full charge capacity on the basis of the voltage value when an amount of change in the voltage value is less than or equal to a prescribed amount even after a prescribed time period elapses in the charged state. Also, the battery/VCU controller may estimate a capacity changed (specifically, reduced) on the basis of the number of times of charging, the temperature, or the like as a full charge capacity with respect to an initial capacity obtained from the data generation device  150  to be described below. The battery/VCU controller derives the SOC by dividing the remaining capacity by the full charge capacity (SOC=(remaining capacity/full charge capacity)×100[%]). 
     Also, the battery/VCU controller outputs control information for controlling the charging of the battery  140  to the VCU  134  on the basis of the derived SOC. For example, the battery/VCU controller outputs control information for performing control so that a charging process is performed until a prescribed SOC (a set value or a fixed value) is reached at the time of charging to the VCU  134 . Also, the battery/VCU controller may be configured to generate notification information for prompting an occupant (a vehicle user) of the vehicle  100  to charge the battery  140  in a charging facility  400  or the like when the derived SOC becomes less than or equal to a threshold value and output the generated notification information to the display device  180 . Also, the battery/VCU controller outputs charging execution information such as the remaining capacity and an SOC to the data generation device  150 . 
     The battery  140  is, for example, a secondary battery such as a lithium-ion battery. The battery  140  stores, for example, electric power for traveling. Specifically, the battery  140  stores electric power supplied from the charging facility  400  outside the vehicle  100  and electric power (regenerative electric power) generated by the motor  112 . Also, the battery  140  is discharged for the vehicle  100  for traveling or is discharged for supplying electric power to in-vehicle equipment (for example, the communication device  160  or a display device  180 ) or the like. Although it is assumed that one battery  140  is simply mounted in the vehicle  100  in the following description, the battery  140  may be a battery module including a plurality of battery packs. In this case, each battery bag can be sold. 
     The battery sensor  142  includes, for example, a voltage sensor that detects a voltage value of the battery  140 , a current sensor that detects a current value of the battery  140 , and a temperature sensor that detects a temperature of the battery  140 . The battery sensor  142  outputs the voltage value, the current value, and the temperature detected from the sensors to the controller  136  and the data generation device  150 . 
     The data generation device  150  includes, for example, a generator  152  and a storage  154 . The storage  154  stores, for example, initial information about the battery  140 . The initial information is, for example, data stored when the battery  140  is mounted in the vehicle  100 . The initial information includes, for example, a product name, a model, a manufacturer name, a manufacturing date, a use start date, a scheduled use end date, an initial capacity, an initial voltage, and the like of the battery  140 . The use start date may be the manufacturing date of the battery  140  or a date when the battery  140  has been mounted in the vehicle  100 . As the scheduled use end date, a date after a prescribed period from the use start date is set. The prescribed period may be a fixed period or a period set according to the performance of the battery  140  or a warranty period thereof. The initial capacity is an initial full charge capacity (for example, at the time of manufacturing or at the start of use). Also, the initial voltage is an initial voltage value. The initial information is fixed information that does not change. 
     The generator  152  adds 1 to the number of times of charging at a timing when charging is completed after the start of charging on the basis of the charging execution information output by the controller  136 . Information about the number of times of charging is stored in the storage  154 . The generator  152  generates battery data (an example of secondary battery information) including the initial information stored in the storage  154 , the number of times of charging, and the charging execution information. Also, the generator  152  may include the state rank of the battery  140  (an example of the state information) in the battery data. The state rank is derived on the basis of, for example, a state of health (SOH) (a battery deterioration state). The SOH is calculated, for example, by dividing the full charge capacity by the initial capacity (SOH=(full charge capacity/initial capacity)×100[%]). In the embodiment, when the SOH value is larger, a rank indicating a better battery state (a higher rank) is assigned. Also, the state rank may be an SOH. Also, the generator  152  may cause information about the next vehicle inspection date of the vehicle  100  (an inspection date of the vehicle  100  determined by the national government or the like) to be included in the battery data. The generator  152  may cause the generated battery data to be transmitted to the information processing device  300  using the communication device  160  according to a timing when the battery data is generated or updated, a timing when the battery  140  is charged, or a prescribed interval. Also, the generator  152  may cause the storage  154  to store the battery data. 
     The communication device  160  includes a wireless module for connecting to a cellular network or a Wi-Fi network. The communication device  160  transmits, for example, information output by the controller  136 , the data generation device  150 , the display device  180 , and the like to the information processing device  300  via the network NW. Also, the communication device  160  receives the information transmitted by the information processing device  300  via the network NW. The communication device  160  outputs the received information to the display device  180  or the like. 
     The charging port  170  is provided oriented toward outside of the vehicle body of the vehicle  100 . The charging port  170  is connected to the charging facility  400  via a charging cable  420 . The charging facility  400  is provided, for example, in a parking lot of a home or a commercial facility or the like. The charging cable  420  includes a first plug  422  and a second plug  424 . The first plug  422  is connected to the charging facility  400  and the second plug  424  is connected to the charging port  170 . The electric power supplied from the charging facility  400  is supplied to the charging port  170  via the charging cable  420 . 
     Also, the charging cable  420  includes a signal cable attached to the power cable. The signal cable mediates communication between the vehicle  100  and the charging facility  400 . 
     The converter  172  is provided between the charging port  170  and the battery  140 . The converter  172  converts an AC introduced from the charging facility  400  via the charging port  170  into a DC. The converter  172  outputs the DC after the conversion to the battery  140 . Thereby, the battery  140  is charged with the electric power from the charging facility  400 . Also, the charging of the battery  140  is controlled by the VCU  134  so that the charging is completed in a prescribed SOC. 
     The display device  180  includes, for example, a display  182  and a display controller  184 . The display  182  is, for example, a liquid crystal display (LCD), an organic electro luminescence (EL) display device, or the like. Also, the display  182  may have a function as an operation element that receives an input operation by contact with the operator&#39;s finger or the like, such as a touch panel. Also, the display  182  is, for example, a multi-information display (MID) and displays information according to the control of the display controller  184 . Also, the display  182  is provided at a prescribed position in the vehicle cabin of the vehicle  100 . 
       FIG. 3  is a diagram for describing a position of the display  182  provided in the vehicle cabin of the vehicle  100 . In the example of  FIG. 3 , a first display  182 A, a second display  182 B, and a third display  182 C are provided as the display  182 . 
     The first display  182 A is arranged on, for example, a meter panel including an instrument such as a vehicle speed meter provided on the instrument panel  192  in front of a driver&#39;s seat  191 A and a passenger seat  191 B. For example, the second display  182 B and the third display  182 C are arranged near the left front of the driver&#39;s seat  191 A in the instrument panel  192  within the vehicle cabin. For example, the second display  182 B is arranged on the central portion of the instrument panel  192 . The third display  182 C is arranged above the second display  182 B on the instrument panel  192 . The second display  182 B is arranged at a position that is less visible to the driver of the vehicle  100  during driving or surrounding monitoring than the third display  182 C and does not interfere with driving. Compared with the second display  182 B, the third display  182 C is arranged at a position easily allowing visual recognition by the driver of the vehicle  100  (for example, a position allowing visual recognition by the driver with a smaller movement of the line of sight). 
     On each of the first display  182 A, the second display  182 B, and the third display  182 C, information detected by various types of instruments mounted in the vehicle  100  and content such as an image generated by a navigation device (not shown) mounted in the vehicle  100 , a TV program, and a video which is stored in a DVD or downloaded is displayed. Also, information obtained by the controller  136  and the data generation device  150 , information transmitted from the information processing device  300  (for example, provision information), and the like are displayed on the displays. The display controller  184  causes the displays to display the various types of information described above. Also, the display controller  184  performs control so that display content, which is displayed on each display, can be appropriately replaced on the basis of an instruction of the vehicle user or a traveling situation of the vehicle. Also, the display controller  184  may cause the speaker (not shown) included in the display device  180  to output speech corresponding to the display content. Details of the content displayed on the display will be described below. 
     Secondary-Use-Related User Terminal  200   
       FIG. 4  is a diagram showing an example of a functional configuration of the secondary-use-related user terminal  200 . The secondary-use-related user terminal  200  includes, for example, a communicator  310 , an input  220 , a display  230 , a speaker  240 , a purchase requestor  250 , an acquirer  260 , an output controller  270 , and a storage  280 . The purchase requestor  250 , the acquirer  260 , and the output controller  270  are implemented by, for example, a hardware processor such as a central processing unit (CPU) executing a program (software). Also, some or all of the above components may be implemented by hardware (including a circuit; circuitry) such as a large-scale integration (LSI) circuit, an application specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or a graphics processing unit (GPU) or may be implemented by software and hardware in cooperation. The above program may be pre-stored in a storage device (a storage device including a non-transitory storage medium, for example, the storage  280 ) such as hard disk drive (HDD) or a flash memory of the secondary-use-related user terminal  200  or may be stored in a removable storage medium such as a DVD, a CD-ROM, or a memory card and installed in the storage device of the secondary-use-related user terminal  200  when the storage medium (the non-transitory storage medium) is mounted in a drive device, a card slot, or the like. 
     The communicator  310  communicates with the information processing device  300  and other external devices using, for example, the network NW. 
     For example, the input  220  receives an input of a user U 1  by operating various types of keys or buttons, or the like. The display  230  is, for example, an LCD, an organic EL display device, or the like. The input  220  may be configured integrally with the display  230  as a touch panel. The display  230  displays information necessary for using the secondary-use-related user terminal  200  according to the control of the output controller  270 . For example, the speaker  240  outputs prescribed speech according to the control of the output controller  270 . 
     The purchase requestor  250  acquires request information for the secondary-use-related user to purchase the battery and transmits the acquired request information to the information processing device  300 . Batteries for which purchase requests are made include new batteries and used batteries (batteries for secondary use). Hereinafter, a case in which a used battery is purchased will be described in particular. The request information includes, for example, values of a type (a product name, a model, or the like), a state (for example, a state rank), a quantity, a purchase price of the battery to be purchased, and the like. For example, the purchase requestor  250  causes the display  230  to display an input image for inputting the request information according to the control of the output controller  270  and acquires the request information on the basis of the information input by the input  220 . 
     The acquirer  260  acquires a response to the request information from the information processing device  300 , causes the acquired response information to be displayed on the display  230  according to the control of the output controller  270 , and causes speech corresponding to the response information to be output from the speaker  240 . Also, the acquirer  260  may cause the storage  280  to store the response information acquired from the information processing device  300 . 
     The output controller  270  controls content to be displayed on the display  230  and content of the speech to be output by the speaker  240 . Also, the output controller  270  may cause various types of information necessary for using the secondary-use-related user terminal  200  to be output from the display  230  and the speaker  240 . 
     The storage  280  is implemented by, for example, an HDD, a flash memory, an EEPROM, a ROM, a RAM, or the like. The storage  280  stores, for example, request information, a program, and various types of other information. 
     Information Processing Device  300   
       FIG. 5  is a diagram showing an example of a functional configuration of the information processing device  300 . The information processing device  300  includes, for example, a communicator  310 , an acquirer  320 , an analyzer  330 , a provider  340 , and a storage  350 . The analyzer  330  and the provider  340  are implemented by, for example, a hardware processor such as a CPU executing a program (software). Some or all of the above components may be implemented by hardware (including a circuit; circuitry) such as an LSI circuit, an ASIC, an FPGA, or a GPU or may be implemented by software and hardware in cooperation. The program may be pre-stored in a storage device (a non-transitory storage medium) such as an HDD or a flash memory or may be stored in a removable storage medium (the non-transitory storage medium) such as a DVD or a CD-ROM and installed in the storage device when the storage medium is mounted in a drive device. The storage  350  is implemented by the storage device described above. 
     The communicator  310  receives various types of information transmitted by one or more vehicles  100  or one or more secondary-use-related user terminals  200  via the network NW. Also, the communicator  310  transmits an analysis result of the analyzer  330  and provision data (an example of provision information) generated by the provider  340  to the vehicle  100  and the secondary-use-related user terminal  200 . 
     The acquirer  320  acquires the battery data transmitted by each of the one or more vehicles  100 , collects the acquired battery data to generate collected data  352 , and causes the storage  350  to store the generated collected data  352 . 
       FIG. 6  is a diagram for describing content of the collected data  352 . In the collected data  352 , a vehicle ID, which is identification information for identifying the vehicle  100 , is associated with position information, acquisition date and time information, a battery ID, which is identification information for identifying the battery  140 , an SOC [%], the remaining capacity [kWh], a full charge capacity [kWh], the number of times of charging [times], battery information, and a vehicle inspection date. The battery information includes, for example, initial information, a state rank, and the like. The position information is, for example, position information (for example, latitude and longitude) of the vehicle that has transmitted the battery data. The acquisition date and time information is about a date and time when the vehicle  100  has transmitted the battery data or when the communicator  310  has received the battery data. 
     Also, the acquirer  320  acquires the battery request information transmitted from the secondary-use-related user terminal  200  and causes the storage  350  to store the acquired request information as purchase request data  354 .  FIG. 7  is a diagram for describing the content of the purchase request data  354 . In the purchase request data  354 , for example, a terminal ID, which is identification information for identifying the secondary-use-related user terminal  200 , is associated with position information, request date and time information, battery information, a required quantity [pieces], and a purchase price [yen/piece]. The position information in  FIG. 7  is, for example, information about a position (a region) where the purchased battery is used. The position information is, for example, information about a position of the factory where the battery is installed, an address of an owner of the vehicle, or a region thereof. The request date and time information is about, for example, a date and time when the vehicle  100  has transmitted the battery data or when the communicator  310  has received the request information. The required battery information includes, for example, information about a type and a state of the battery desired to be purchased. The required quantity is the number of batteries desired to be purchased. The purchase price is a desired purchase price per battery. The acquirer  320  generates the purchase request data  354  in which the request information is associated with the terminal ID of the secondary-use-related user terminal  200  that has transmitted the request information. 
     The analyzer  330  analyzes value information of the battery using the collected data  352  and/or the purchase request data  354  acquired by the acquirer  320  and generates analysis data  356 .  FIG. 8  is a diagram for describing the content of the analysis data  356 . In the analysis data  356 , for example, a region ID, which is identification information for identifying the region, is associated with a state rank for identifying a state of the battery, a required quantity [pieces], a total capacity [kWh], and an average purchase price [yen/piece]. 
     The analyzer  330  performs a statistical process for request information for each prescribed region on the basis of the position information included in the purchase request data  354 . Also, the analyzer  330  analyzes value information of the battery on the basis of how many batteries of which state rank are insufficient in the associated region for classified request information. For example, in the example of  FIG. 8 , the analyzer  330  can sell a battery of a state rank “R3” in a region ID “A1” at a price higher than the average purchase price at present because the required quantity of the state rank R3 is large in the region A1 and makes value evaluation indicating that a decrease in the purchase price will be small in the future. Also, the analyzer  330  may estimate a future degree of deterioration of the battery for each vehicle or each battery included in the collected data  352  or analyze a price change based on the future degree of deterioration. Also, the analyzer  330  may analyze how the battery can be used to limit the deterioration of the battery from a previous change in the degree of deterioration of the battery. 
     Also, the analyzer  330  may analyze current and/or future values of the battery on the basis of a balance (a ratio) between supply and demand based on the collected data  352  and the purchase request data  354  and the like. Also, an analysis method in the analyzer  330  is not limited to this and more appropriate analysis may be performed using a prescribed statistical process using regression analysis, machine learning, or the like based on history information of past values, and artificial intelligence (AI) technology, or the like. 
     The provider  340  transmits a statistical result and value information of the battery analyzed by the analyzer  330  to the vehicle  100  and the secondary-use-related user terminal  200  via the communicator  310 . For example, the provider  340  generates information about a state and a market value of the battery  140 , information about how to use the battery  140  so that deterioration is limited, information about a timing of selling the battery  140 , and the like for the user of the vehicle  100  and transmits the generated information (provision data) to the vehicle  100 . Also, when there is an instruction for selling the battery  140  from the vehicle  100 , the provider  340  may provide information about a battery to the secondary-use-related user terminal  200  requesting the battery associated with the instruction. 
     Hereinafter, details of the content provided from the provider  340  and displayed by the display device  180  of the vehicle  100  will be described. Also, although an image displayed in at least a part of a display region of the first display  182 A will be described below, the same or similar information may be displayed in other displays. 
     The provider  340  generates an image including information about the state of the battery  140  of the vehicle  100  and transmits the generated image to the vehicle  100 . The vehicle  100  displays an image provided from the information processing device  300 . 
       FIG. 9  is a diagram showing an example of an image IM 1  including the battery state. The image IM 1  includes a heading display region A 11 , a provision information display region A 12 , and a graphical user interface (GUI) switch display region A 13 . In the example of  FIG. 9 , the text information “battery state” is displayed in the heading display region A 11 . 
     In the provision information display region A 12 , the battery data generated by the generator  152  or the collected data corresponding to the vehicle  100  provided by the information provider is displayed. In the example of  FIG. 9 , for example, battery information, an SOC [%], the remaining capacity [kWh], a full charge capacity [kWh], the number of times of charging [times], a use start date, and a scheduled use end date are displayed in the provision information display region A 12 . Also, the above-described display content may be acquired from the battery data generated by the data generation device  150 . 
     In the GUI switch display region A 13 , for example, icons for receiving an instruction from the user are displayed. The icons include, for example, an icon IC 11  on which the text “OK” is written and an icon IC 12  on which the text “battery price” are written. When the icon IC 11  or the icon IC 12  has been selected by the user, the display controller  184  executes processes corresponding to the selected icons IC 11  and IC 12 . 
     For example, when the icon IC 11  has been selected, the display controller  184  ends the display of the image IM 1 . Also, when the icon IC 12  has been selected, the display controller  184  causes the first display  182 A to display information about the provision data provided by the information processing device  300 . 
       FIG. 10  is a diagram showing an example of an image IM 2  including information about the battery price. The image IM 2  includes a heading display region A 21 , a provision information display region A 22 , and a GUI switch display region A 23 . In the example of  FIG. 10 , the text information “battery price”, the state rank of the battery  140  included in the provision data, and the price “OOO yen” at the time of sale at the present time are displayed in the heading display region A 21 . The state rank may be acquired from the battery data generated by the data generation device  150 . Also, the price is a price analyzed by the analyzer on the basis of the average purchase price and the required quantity in the region corresponding to the position information of the vehicle. 
     In the provision information display region A 22 , a graph showing a relationship between the years of use [years] of the price of the battery  140  and the price [yen] included in the provision data acquired by the information processing device  300  is displayed. In the graph of the provision information display region A 22 , a line BA 1  indicates an upper limit of a market price of a battery which is the same as the battery  140  and a line BA 2  indicates a lower limit of the market price of the battery which is the same as the battery  140 . Also, the graph may indicate information about the current number of years of use of the battery  140  and a vehicle inspection date. For example, the current number of years of use or a position of the next vehicle inspection date is plotted on the axis representing the number of years of use in the provision information display region A 22 . By providing the above information to the occupants, it is possible to more appropriately provide the vehicle user with not only the current price of the battery  140  but also the change in the price over time. Also, it is possible to improve the motivation to perform the sale of the battery (including replacement thereof) by providing the vehicle user with information such as the vehicle inspection date. 
     In the GUI switch display region A 23 , for example, icons for receiving an instruction from the user are displayed. The icons include, for example, an icon IC 21  on which the text “OK” is written, an icon IC 22  on which the text “sale” is written, and an icon IC 23  on which the text “advice” is written. When the icons IC 21  to IC 23  have been selected by the user, the display controller  184  executes processes corresponding to the selected icons IC 21  to IC 23 . 
     For example, when the icon IC 21  has been selected, the display controller  184  ends the display of the image IM 2 . Also, when the icon IC 22  has been selected, the display controller  184  transmits information indicating that the user intends to sell the battery  140  to the information processing device  300 . Also, when the icon IC 21  has been selected, the display controller  184  causes the first display  182 A to display an image IM 3  including information about advice on use for limiting deterioration of the battery obtained from the information processing device  300 . 
       FIG. 11  is a diagram showing an example of the image IM 3  including information about battery use advice. The image IM 3  includes a heading display region A 31 , an advice information display region A 32 , and a GUI switch display region A 33 . In the example of  FIG. 11 , text information such as “battery use advice” is displayed in the heading display region A 31 . 
     In the advice information display region A 32 , a graph related to deterioration prediction showing a relationship between the number of years of use [years] of the price of the battery  140  and a degree of deterioration and information related to the advice for future use of the battery included in the provision data acquired by the information processing device  300  are displayed. In the graph, a line DD 1  indicates deterioration prediction when the vehicle user continues the current use state of the battery  140  and a line DD 2  indicates deterioration prediction when the advice for future use of the battery is executed. In the advice information display region A 32 , text information such as “By performing OOO, deterioration of the battery can be limited.” is displayed as the advice for future use of the battery. By advising the user on the usage method for limiting deterioration in this way, it is possible to improve the usage method of the battery of the user and it is possible to promote the improvement of the value of the battery to be sold. 
     In the GUI switch display region A 33 , for example, icons for receiving an instruction from the user are displayed. The icons include, for example, an icon IC 31  on which the text “OK” are written. The display controller  184  ends the display of the image IM 3  when the icon IC 31  has been selected by the user. In this case, the display controller  184  may cause the image IM 2  to be displayed again. 
     Also, when an icon IC 23  on which the text “advice” is written has been selected in the image IM 2 , the display controller  184  may cause the first display  182 A to display an image related to advice on a battery sale period instead of (or in addition to) advice on the usage method of the battery  140 . 
       FIG. 12  is a diagram showing an example of an image IM 4  including information about battery sale advice. The image IM 4  includes a heading display region A 41 , an advice information display region A 42 , and a GUI switch display region A 43 . In the example of  FIG. 12 , text information such as “battery sale advice” is displayed in the heading display region A 41 . 
     In the advice information display region A 42 , information about the sale advice acquired by the information processing device  300  is displayed. In the example of  FIG. 12 , in the advice information display region A 42 , text information such as “The purchase price of the battery currently in use is OOO yen.” and “We recommend you to sell the battery within two years because the price is expected to be halved after two years.” is displayed. Thereby, the user can more appropriately ascertain a timing when the battery  140  is sold. 
     In the GUI switch display region A 43 , for example, icons for receiving an instruction from the user are displayed. The icons include, for example, the icon IC 41  on which the text “OK” are written. The display controller  184  ends the display of the image IM 4  when the icon IC 41  has been selected by the user. In this case, the display controller  184  may cause the image IM 2  to be displayed again. 
     The above-described images IM 1  to IM 4  are provided to the vehicle  100  at a prescribed timing by the provider  340 . For example, the prescribed timing is a prescribed interval or a timing of an instruction by the vehicle  100 . For example, the display controller  184  may cause the image IM 1  to be constantly displayed in a part of the display region of the display when the vehicle  100  is activated (when the ignition is turned on) and the above-described images IM 1  to IM 4  may be displayed on a part of the operated display when the vehicle  100  is stopped or when the vehicle user has operated any one of the first to third displays  182 A to  182 C. Also, the display controller  184  may perform control so that, when the vehicle  100  is traveling, the second display  182 B is displayed without interfering with the surrounding monitoring and driving of the vehicle user (particularly, the driver). Also, the display controller  184  may cause a part or all of the above-described information about the images IM 1  to IM 4  to be switched and displayed at prescribed time intervals or may cause one or more screens to display a part or all of the above-described information about the images IM 1  to IM 4  at the same time. Also, the display controller  184  may select the icon IC of each image described above, input speech from the vehicle user, and perform an image switching or instruction process or the like on the basis of a result of analyzing the input speech. 
     Processing Sequence 
       FIG. 13  is a sequence showing an example of a process executed by the information processing system  1  in the embodiment. Hereinafter, a processing flow will be described using the vehicle  100 , the information processing device  300 , and the secondary-use-related user terminal  200 . First, the vehicle  100  acquires information (for example, initial information, the number of times of charging, and charging execution information) about the battery  140  mounted in the vehicle  100  (step S 100 ). Next, the data generation device  150  generates battery data (step S 102 ). Next, the communication device  160  transmits the battery data to the information processing device  300  (step S 104 ). 
     Next, in the secondary-use-related user terminal  200 , the purchase requestor  250  generates request information about the battery to be secondarily used (step S 106 ) and causes the information processing device  300  to transmit the generated request information via the communicator  210  (step S 108 ). 
     Next, in the information processing device  300 , the analyzer  330  analyzes a market value based on the supply and demand of the battery on the basis of the battery data transmitted from the vehicle  100  and the request information transmitted from the secondary-use-related user terminal  200  (step S 110 ). Next, the provider  340  generates the provision data based on the analysis result (step S 112 ) and transmits the generated provision data to the vehicle  100  (step S 114 ). 
     In the vehicle  100 , the display device  180  causes the display  182  to display information about the battery  140  and battery data or causes the display  182  to display the data provided by the information processing device  300  (step S 116 ). Also, when there is an instruction from the user as described above, the display device  180  may make an inquiry to the information processing device  300  (step S 118 ), acquire an inquiry result (step S 120 ), and cause the display  182  to display the inquiry result (step S 122 ). Also, when an instruction for selling the battery has been received from the user, the display device  180  transmits information about the sale instruction to the information processing device  300  (step S 124 ). 
     In the information processing device  300 , when the acquirer  320  receives the sale instruction from the vehicle  100 , the acquirer  320  identifies the secondary-use-related user terminal  200  requesting the purchase of the battery for which the sale instruction is given and transmits the battery information and response information about the battery purchase request to the identified secondary-use-related user terminal  200  (step S 126 ). In the secondary-use-related user terminal  200 , the output controller  270  displays the response information acquired by the acquirer  260  on the display  230  (step S 128 ). Also, the acquirer  260  transmits purchase determination information to the information processing device  300  when the secondary-use-related user gives a purchase instruction (step S 130 ). Thereby, the process of the present sequence ends. In the example of  FIG. 13 , after the processing of step S 112 , the information processing device  300  may also transmit the provision data and the information about the analysis result to the secondary-use-related user terminal  200  and cause the secondary-use-related user terminal  200  to display the provision data and the information about the analysis result. 
     The information processing device according to the above-described embodiment includes the acquirer  320  configured to acquire battery data transmitted from the vehicle  100  equipped with the battery  140  storing electric power for traveling; the analyzer  330  configured to analyze value information of the battery  140  on the basis of the battery data acquired by the acquirer  320  and request information from a secondary-use-related user who uses the battery  140  secondarily; and the provider  340  configured to provide provision data about a sale of the battery  140  on the basis of the value information of the battery  140  analyzed by the analyzer  330 , whereby it is possible to promote the distribution of the secondary battery for secondary use in a better state. 
     Specifically, according to the present embodiment, the user of the vehicle can more appropriately ascertain the value of the battery and the guideline at the time of selling from the time when the vehicle is in use. Also, by allowing the user of the vehicle to recognize that the value changes with the battery state, the motivation to limit the deterioration of the battery is increased and the quality of the battery can be expected to be improved. As a result, it is possible to supply the battery for secondary use in a good state to the secondary-use-related user. Therefore, the secondary-use-related user can secure a higher-quality battery and ascertain the number of batteries, which enables more appropriate business development. 
     Although modes for carrying out the present invention have been described using embodiments, the present invention is not limited to the embodiments, and various modifications and substitutions can also be made without departing from the scope and spirit of the present invention.
