The following embodiments do not limit the present invention covered by claims. Also, not all combinations of features described in the embodiments are necessary for solutions of the present invention. Although a vehicle  10  is assumed to be an electric vehicle, the vehicle  10  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  10 . 
     First Embodiment

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. 
     [Vehicle  10 ] 
       FIG. 2  is a diagram showing an example of a configuration of the vehicle  10 . As shown in  FIG. 2 , the vehicle  10  includes, for example, a motor  12 , drive wheels  14 , a brake device  16 , a vehicle sensor  20 , a power control unit (PCU)  30 , a battery  40 , battery sensors  42  such as a voltage sensor, a current sensor, and a temperature sensor, a data generation device  52 , a communication device  54 , a display device  60 , a charging port  70 , and a converter  72 . 
     The motor  12  is, for example, a three-phase alternating current (AC) electric motor. A rotor of the motor  12  is connected to the drive wheels  14 . The motor  12  outputs motive power to the drive wheels  14  using electric power that is supplied. Also, the motor  12  generates electric power using kinetic energy of the vehicle when the vehicle is decelerated. 
     The brake device  16  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  16  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  16  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. 
     The vehicle sensor  20  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 control unit  36 . 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 control unit  36  and the display device  60 . 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 control unit  36 . 
     The PCU  30  includes, for example, a converter  32 , a voltage control unit (VCU)  34 , and the control unit  36 . Also, a group of the above components is configured as the PCU  34  as only an example and these components may be arranged in a distributed form. 
     The converter  32  is, for example, an AC-direct current (DC) converter. A DC side terminal of the converter  32  is connected to a DC link DL. The battery  40  is connected to the DC link DL via the VCU  34 . The converter  32  converts an AC generated by the motor  12  into a DC and outputs the DC to the DC link DL. 
     The VCU  34  is, for example, a DC-DC converter. The VCU  34  boosts electric power supplied by the battery  40  and outputs the boosted electric power to the DC link DL. 
     The control unit  36  includes, for example, a motor control unit, a brake control unit, and a battery/VCU control unit. The motor control unit, the brake control unit, and the battery/VCU control unit may be replaced with separate control devices such as a motor ECU, a brake ECU, and a battery ECU. 
     The motor control unit controls the motor  12  on the basis of an output of the vehicle sensor  20 . The brake control unit controls the brake device  16  on the basis of an output of the vehicle sensor  20 . The battery/VCU control unit calculates a state of charge (SOC) (hereinafter also referred to as a “battery charge rate”) of the battery  40  on the basis of an output of the battery sensor  42  attached to the battery  40 . In battery/VCU control, the calculated SOC is output to the VCU  34  and the data generation device  52 . The VCU  34  causes a voltage of the DC link DL to be raised in accordance with an instruction from the battery/VCU control unit. 
     The battery/VCU control unit confirms that the battery  40  has been charged on the basis of an output of the battery sensor. The battery/VCU control unit outputs charging execution information to the data generation device  52  when the battery  40  has been charged. 
     The battery  40  is, for example, a secondary battery such as a lithium-ion battery.

The battery sensors  42  include, for example, the current sensor, the voltage sensor, and the temperature sensor. The battery sensors  42  detect, for example, a current value, a voltage value, and a temperature of the battery  40 . The battery sensors  42  output the detected current value, voltage value, and temperature and the like to the control unit  36 . When the calculated SOC is output to the data generation device  52 , the control unit  36  outputs the current value, the voltage value, the temperature, and the like output by the battery sensors  42  to the data generation device  52 .

The data generation device  52  calculates a charge capacity and a full charge capacity of the battery  40  using the current value, the voltage value, the temperature, the SOC, and the like of the battery  40  output by the control unit  36 . The data generation device  52  generates collected data  152  on the basis of the initial information stored in the storage, the cycle count, and the information output by the control unit  36 . The data generation device  52  includes a battery-equipped vehicle model, which is a vehicle model of the vehicle  10 , in the collected data  152 .

The in-vehicle battery information includes data such as the SOC, the current value, the voltage value, the temperature, the remaining capacity, the full charge capacity, and the maximum cruising distance of the battery  40 . The above data may be displayed numerically or may be displayed as icons or the like. Also, an accurate numerical value may be displayed or a numerical value different from the accurate numerical value such as a numerical value obtained by correcting the accurate numerical value may be displayed. 
     The communication device  54  includes a wireless module for connecting to a cellular network or a Wi-Fi network. The communication device  54  acquires the collected data  152  output by the data generation device  52  and transmits the collected data  152  to the information processing device  100  via the network NW shown in  FIG. 1 . Also, the communication device  54  receives the information transmitted by the information processing device  100  via the network NW. The communication device  54  outputs the received information to the display device  60 . 
     The display device  60  includes, for example, a display  62  and a display controller  64 . The display  62  is, for example, a multi-information display (MID), and displays information based on control of the display controller  64 . The display controller  64  causes the display  62  to display the in-vehicle battery information of the in-vehicle battery or the battery  40  other than the in-vehicle battery in accordance with the information output by the control unit  36  and the communication device  54 . 
     The charging port  70  is provided oriented toward outside of the vehicle body of the vehicle  10 . The charging port  70  is connected to the charger  200  via a charging cable  220 .

The converter  72  outputs the DC obtained in the conversion to the battery  40 . 
       FIG. 4  is a diagram showing an example of a configuration of a cabin of the vehicle  10 . As shown in  FIG. 4 , the vehicle  10  includes, for example, the display device  60 , a steering switch  90 , a steering wheel  91  that controls the steering of the vehicle  10 , a front windshield  92  that separates the outside and the inside of the vehicle, an instrument panel  93 , a first display device  94 , a second display device  95 , and an in-wheel area display  97 . 
     The display device  60  is arranged, for example, in a meter panel unit including an instrument such as a vehicle speedometer provided on the instrument panel  93  in front of the driver&#39;s seat. The steering switch  90  is arranged on the steering wheel  91 . The steering switch  90  is an input device arranged at a position where an operation by the driver&#39;s finger holding the steering wheel  91  is possible. For example, the steering switch  90  outputs a signal based on a pressing operation by the driver&#39;s finger and outputs a signal for switching the display of the display device  60 . The display controller  64  ( FIG. 2 ) of the display device  60  switches the display of the display  62  in accordance with the signal output by the steering switch  90 . 
     The front windshield  92  is a member having light transmission. The first display device  94  and the second display device  95  are provided near the left front of the driver&#39;s seat  96  on the instrument panel  93  within the cabin. 
     The first display device  94  is, for example, a liquid crystal display arranged on a central portion of the instrument panel  93 . The first display device  94  is, for example, a touch panel that receives an input operation by the contact of an operator&#39;s finger. For example, the first display device  94  displays an image corresponding to a navigation process executed by a navigation device (not shown) mounted in the vehicle  10  or displays a video of the other party and the like on a videophone. 
     The second display device  95  is a liquid crystal display arranged above the first display device  94  on the instrument panel  93 . The second display device  95  is, for example, a touch panel that receives an input operation by the contact of the operator&#39;s finger. The second display device  95  is arranged at a position where visual recognition of the driver of the vehicle  10  is easy as compared with the first display device  94 . Compared with the first display device  94 , the second display device  95  is arranged at a position allowing visual recognition by the driver who is driving the vehicle  10  with a smaller movement of a line of sight. The second display device  95  is arranged, for example, at a position closer to the front windshield  92  than the first display device  94 , a position closer to a gaze range in front of the driver in an appropriate driving posture than the first display device  94 , or the like.

     [Information Processing Device  100 ] 
     The information processing device  100  shown in  FIG. 1  includes, for example, a communication unit (a reception unit)  110 , an analysis unit  120 , a provision unit  130 , and a storage  150 . The analysis unit  120  and the provision unit  130  are implemented by, for example, a hardware processor such as a central processing unit (CPU) executing a program (software). Some or all of these components may be implemented by hardware (including a circuit unit; 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 program may be prestored in a storage device (a non-transitory storage medium) such as a hard disk drive (HDD) or a flash memory or may be stored in a removable storage medium (a non-transitory storage medium) such as a DVD or CD-ROM and installed when the storage medium is mounted in a drive device. The storage  150  is implemented by the storage device described above. 
     Under the assumption that a process of the information processing device  100  is performed, each of the plurality of vehicles  10  generates the collected data  152  ( FIG. 3 ) and transmits the collected data  152  ( FIG. 3 ) to the information processing device  100  using the communication device  54 . The vehicle  10  may generate the collected data  152  every prescribed time period, for example, every hour or every day or may generate the collected data  152  on the basis of an instruction of the user of the vehicle  10  and the like. Also, the vehicle  10  may transmit the collected data  152  in response to a request of the information processing device  100 . Also, the vehicle  10  may be configured to transmit the collected data  152  when a prescribed condition is satisfied, for example, when the load of the battery exceeds a certain amount, or when the SOC or the full charge capacity falls below a prescribed value. Also, the vehicle  10  may transmit the collected data  152  at any one or more of the above timings. 
     The communication unit  110  receives the collected data  152  transmitted by each of the plurality of vehicles  10 . The communication unit  110  outputs the collected data  152 , which has been received, to the analysis unit  120 . 
     The analysis unit  120  generates analysis data by analyzing a large number of pieces of collected data  152  received by the communication unit  110  and stored in the storage  150 .  FIG. 5  is a diagram showing an example of analysis data  154 . The analysis data  154  is data obtained by aggregating and analyzing a plurality of pieces of collected data  152  for each type of battery  40 . Thus, the analysis data  154  is generated for each type of battery. The analysis data  154  is an example of analysis information. 
     For example, the analysis unit  120  classifies and summarizes items included in the plurality of pieces of collected data  152  transmitted from the vehicle  10  in which the battery A is mounted as the data of the battery “A” according to each battery-equipped vehicle model. In the example of  FIG. 5 , the analysis unit  120  summarizes n pieces of collected data  152  from (1) to (n) as items of the battery “A” mounted in a battery-equipped vehicle model “a.” The analysis unit  120  summarizes m pieces of collected data  152  from (1) to (m) as items of the battery “A” mounted in a battery-equipped vehicle model “b.” 
     Because the collected data  152  has not been obtained for the battery “A” mounted in the battery-equipped vehicle model “c,” the analysis unit  120  does not summarize data for each item of the battery “A” mounted in the battery-equipped vehicle model “c.” Regarding the battery “A” mounted in the vehicle  10  of another battery-equipped vehicle model, the analysis unit  120  summarizes the collected data  152  as in the battery-equipped vehicle models “a” and “b” within a range in which the collected data  152  has been obtained. 
     In the analysis unit  120 , the collected data  152  is summarized and the analysis data  154  is generated as in the battery “A” with respect to batteries other than the battery “A,” i.e., batteries “B,” “C,” and the like. The analysis unit  120  stores the analysis data  154 , which has been generated, in the storage  150  and the analysis unit  120  reads the analysis data  154  from the storage  150  and updates the analysis data  154  when the collected data  152  has been received. 
     Further, the analysis unit  120  digitizes an actual value of a width of durability after each of a plurality of types of prescribed periods, specifically, two types of periods such as 3 years or 5 years, with respect to a relationship between a type of battery and a battery-equipped vehicle model. The durability refers to a ratio of a full charge capacity of the battery  40  at a determination time point to a full charge capacity of the battery  40  at a reference time point. For example, the durability after 3 years is a ratio of a full charge capacity of the battery  40  when 3 years have elapsed since the battery  40  was mounted in the vehicle  10  to a full charge capacity of the battery  40  when the battery  40  was unused as a new product. The reference time point may be a manufacturing date of the battery  40 , a date when the battery  40  was mounted in the vehicle  10 , or any of several days before and after these dates. Alternatively, the reference time point may be any date between the manufacturing date of the battery  40  and the date when the battery  40  was mounted in the vehicle  10  or may be another date. 
     In the example shown in  FIG. 5 , the minimum and maximum values of the durability of the battery “A” mounted in the battery-equipped vehicle model “a” after 3 years is 95% and 98%, respectively, and the minimum and maximum values of the durability thereof after 5 years is 90% and 93%, respectively. The minimum and maximum values of the durability of the battery “A” mounted in the battery-equipped vehicle model “b” after 3 years is 91% and 99%, respectively, and the minimum and maximum values of the durability thereof after 5 years is 88% and 95%, respectively. 
     The analysis unit  120  estimates the durability of a combination of a battery and a battery-equipped vehicle model for which the collected data  152  was not obtained using the durability of another combination of a battery and a battery-equipped vehicle model. In the example shown in  FIG. 5 , the analysis unit  120  estimates the durability after 3 years and the durability after 5 years for all batteries A for which the collected data  152  has been obtained as the durability after 3 years and the durability after 5 years for the battery “A” mounted in the battery-equipped vehicle model “c,” respectively. 
     The analysis unit  120  generates the provision data  156  related to the performance at the time of reuse of the battery  40  on the basis of the analysis data  154 , which has been generated, when an information provision request has been transmitted from the terminal device  300  and/or the used vehicle sales business server  400 . The provision data is an example of provision information. 
       FIG. 6  is a diagram showing an example of the provision data  156 . As shown in  FIG. 6 , the provision data  156  is data showing the durability after 3 years and the durability after 5 years for each combination of the type of battery and the battery-equipped vehicle model. Here, the analysis unit  120  obtains the durability after 3 years and the durability after 5 years for each combination of the battery  40  and the battery-equipped vehicle model from data classified for each battery  40  in the analysis data  154 . 
     When the analysis data  154  includes the durability after 3 years and the durability after 5 years for each combination of a battery  40  and a battery-equipped vehicle model, the analysis unit  120  uses numerical values thereof as they are as the provision data  156 . When the analysis data  154  does not include the durability after 3 years and the durability after 5 years for each combination of the battery  40  and the battery-equipped vehicle model, the analysis unit  120  uses numerical values estimated using the durability of another combination of a battery and a battery-equipped vehicle model as the provision data  156 . The analysis unit  120  thus collectively generates the durability after 3 years and the durability after 5 years as the provision data  156 . The analysis unit  120  stores the generated provision data  156  in the storage  150  and outputs the provision data  156  to the provision unit  130 . 
     The provision data  156  is, for example, information about the performance of the battery  40  at the time of reuse. Although the performance of the battery  40  at the time of reuse is durability after 3 years and durability after 5 years in the first embodiment, the performance of the battery  40  at the time of reuse may be other information. For example, the performance of the battery  40  at the time of reuse may be durability after the elapse of a period other than 3 or 5 years or may be information other than durability, for example, a full charge capacity, a cycle count, or the like. Alternatively, the provision data  156  may be information for obtaining the performance of the battery  40  at the time of reuse and may be, for example, data of each item included in the analysis data  154 . 
     The provision unit  130  transmits the provision data  156  output by the analysis unit  120  to the terminal device  300  or the used vehicle sales business server  400  that has transmitted the information provision request using the communication unit  110 . The provision unit  130  may be configured to transmit the provision data  156  to a device other than the device that has transmitted the information provision request. 
     The terminal device  300  is, for example, a portable terminal carried by the user U and includes a communication unit, a touch panel, an application execution unit, a display controller, and a storage. The communication unit communicates with the information processing device  100  and other external devices via, for example, a network such as a LAN, a WAN, or the Internet. The touch panel displays various types of information on the basis of control of the display controller, displays various types of keys and/or buttons and the like, and receives the input of the user U by the above operations, for example, an input for transmitting an information provision request to the information processing device  100 . The user U can transmit the information provision request to the information processing device  100  using the terminal device  300 . 
     The application execution unit is implemented by executing a reuse battery information application stored in the storage. For example, the application execution unit communicates with the information processing device  100  via the communication unit and the network, receives the provision data  156  transmitted by the information processing device  100  using the communication unit, and outputs the provision data  156  to the display controller. The display controller causes the touch panel to display information indicating the provision data  156  output by the application execution unit. The application execution unit may cause the information indicating the provision data  156  to be displayed in any way. For example, the information indicating the provision data  156  may be displayed in a text format or the like or may be displayed in a graphic format or the like using an icon or the like. 
     The used vehicle sales business server  400  includes a communication unit, an inputter, a control unit, a display controller, and a display. The communication unit communicates with the information processing device  100  and other external devices via, for example, a network such as a LAN, a WAN, or the Internet. The inputter displays various types of keys and/or buttons and the like, and receives the input of the operator of the used vehicle sales business server  400  by the above operations, for example, an input for transmitting an information provision request to the information processing device  100 . The used vehicle sales business operator can transmit the information provision request to the information processing device  100  using the used vehicle sales business server  400 . The display displays various types of information on the basis of the control of the display controller. 
     For example, the control unit communicates with the information processing device  100  via the communication unit and the network, receives the provision data  156  transmitted by the information processing device  100  using the communication unit, and outputs the provision data  156  to the display controller. The display controller causes the display to display information indicating the provision data  156  output by the control unit. The display controller may cause the information indicating the provision data  156  to be displayed in any way. For example, the information indicating the provision data  156  may be displayed in a text format or the like or may be displayed in a graphic format or the like using an icon or the like. 
     Next, the process in the information processing device  100  will be described.  FIG. 7  is a flowchart showing an example of a process executed by the information processing device  100 . The analysis unit  120  provided in the information processing device  100  first determines whether or not the communication unit  110  has received the collected data  152  transmitted by the vehicle  10  (step S 101 ). 
     When the communication unit  110  determines that the collected data  152  has not been received, the analysis unit  120  proceeds to the processing of step S 105 . When the communication unit  110  determines that the collected data  152  has been received, the analysis unit  120  reads the analysis data  154  stored in the storage  150 . The analysis unit  120  updates the analysis data  154 , which has been read, on the basis of the collected data  152  received by the communication unit  110  (step S 103 ). The analysis unit  120  stores the analysis data  154 , which has been updated, in the storage  150 . The information processing device  100  expands the analysis data  154  by updating the analysis data  154  every time the collected data  152  is acquired. 
     Subsequently, the analysis unit  120  determines whether or not the communication unit  110  has received the information provision request transmitted by the terminal device  300  or the used vehicle sales business server  400  (step S 105 ). When it is determined that the communication unit  110  has not received the information provision request, the analysis unit  120  ends the process shown in  FIG. 7 . 
     When it is determined that the communication unit  110  has received the information provision request, the analysis unit  120  reads the analysis data  154  stored in the storage  150  and generates the provision data  156  using the analysis data  154  that has been read (step S 107 ). After the provision data  156  is generated, the analysis unit  120  stores the analysis data  154 , which has been read, in the storage  150  as it is. 
     Subsequently, the provision unit  130  transmits the analysis data  154  generated by the analysis unit  120  to the terminal device  300  or the used vehicle sales business server  400 , which has transmitted the information provision request, using the communication unit  110  (step S 109 ). Thus, the information processing device  100  ends the process shown in  FIG. 7 . 
     The terminal device  300  or the used vehicle sales business server  400 , which has received the provision data transmitted by the information processing device  100 , provides information of the provision data to the user U or the used vehicle sales business operator. For example, when the user U has transmitted an information provision request to the information processing device  100  using the terminal device  300 , the information processing device  100  transmits the provision data  156  to the terminal device  300 . When the used vehicle sales business operator has transmitted an information provision request to the information processing device  100  using the used vehicle sales business server  400 , the information processing device  100  transmits the provision data  156  to the used vehicle sales business server  400 . 
     For example, in the terminal device  300  to which the provision data  156  has been transmitted by the information processing device  100 , the display controller provided in the terminal device  300  causes the touch panel to display an image showing the information of the provision data  156 . As the image showing the information of the provision data  156 , for example, there is an image in which the durability after 3 years and the durability after 5 years included in the provision data  156  are displayed in a text format with a heading, an icon, or the like. Thus, the information about the performance of the battery  40  at the time of reuse included in the provision data  156  is provided to the user U and/or the used vehicle sales business operator. 
       FIG. 8  is a diagram showing an example of a screen displayed on the terminal device  300 . As shown in  FIG. 8 , on the display of the terminal device  300 , the durability after 3 years and the durability after 5 years of the battery  40  are displayed in a matrix in a text format for each vehicle model as predicted values. Although the durability after 3 years and the durability after 5 years for the battery A are displayed in the example shown in  FIG. 8 , the durability after 3 years and the durability after 5 years for other types of batteries are displayed by redisplaying the screen. 
     The information processing device  100  of the first embodiment generates analysis data  154  on the basis of states of use of batteries  40  in a plurality of vehicles  10 , generates provision data  156  including the durability after 3 years and the durability after 5 years related to the performance of the battery  40  at the time of reuse from the analysis data  154 , and transmits the provision data  156  to the user U, the used vehicle sales business operator, and/or the like. Thus, the user U, the used vehicle sales business operator, and/or the like can obtain information of the performance of the battery  40  at the time of reuse, such as the durability after 3 years and the durability after 5 years. 
     Second Embodiment 
     Next, a second embodiment will be described. In an information processing system  1  of the second embodiment, even if a vehicle  10  equipped with a battery  40  is resold as a used vehicle and its owner changes, information about the performance at the time of reuse such as durability after 3 years and durability after 5 years is provided. A data configuration of the second embodiment is mainly different from that of the first embodiment and differences from the first embodiment will be mainly described in the second embodiment. 
       FIG. 9  is a diagram showing an example of collected data  162  of the second embodiment. As shown in  FIG. 9 , in the collected data  162  in the second embodiment, in addition to each item of the collected data  152  in the first embodiment shown in  FIG. 3 , items of the number of owner changes and the durability at the time of the final transfer are added. A loading history item indicates the number of times the vehicle  10  has been resold as a used vehicle or the like and the owner has changed. 
     When the number of owner changes is “0,” this indicates that the vehicle  10 , which is a new vehicle, is equipped with the battery  40 . When the number of owner changes is “1,” this indicates that the vehicle  10  has been sold as a used vehicle once and the battery  40  is mounted in the vehicle  10  whose owner has changed once. 
     The item of durability at the time of the final transfer indicates a full charge capacity of the battery  40  when the owner last retreated. In the collected data  162 , a date when a start date of use of the vehicle  10  of a current owner instead of a start date of use in another vehicle is stored as the item of “use start date.” 
       FIG. 10  is a diagram showing an example of analysis data  164  of the second embodiment. As shown in  FIG. 12 , the analysis data  164  in the second embodiment is generated as different data for each number of times the owner has been changed for the same type of battery  40 . In  FIG. 12 , the analysis data  164  of a battery “A” is displayed. An analysis unit  120  generates the analysis data  164  for each of “owner count 1,” “owner count 2,” “owner count 3,” and the like as the data of the battery “A.” Although not shown in  FIG. 10 , analysis data is similarly generated for each owner count of the vehicle  10  in batteries “B,” “C,” “D,” and the like. The owner count is a value obtained by adding 1 to the number of owner changes. 
     The analysis unit  120  generates the provision data as in the first embodiment on the basis of the analysis data  164  that has been generated. A provision unit  130  transmits the provision data generated by the analysis unit  120  to a terminal device  300  of a user U and/or a used vehicle sales business server  400  of a used vehicle sales business operator. 
     The information processing device  100  of the first embodiment generates analysis data  154  on the basis of a state of use of the battery  40  in the plurality of vehicles  10  and the like, generates provision data including the durability after 3 years and the durability after 5 years regarding the performance of the battery  40  at the time of reuse of the battery  40  from the analysis data  154 , and transmits the provision data to the user U, the used vehicle sales business operator, and/or the like. Thus, the user U, the used vehicle sales business operator, and/or the like can obtain information about the performance of the battery  40  at the time of reuse, such as the durability after 3 years and the durability after 5 years. The provision data is data for each owner count. Thus, it is possible to confirm a difference in the owner count and the like. Consequently, it is possible to obtain information to which the difference in the owner count and the like are added with respect to information about the performance of the battery  40  at the time of reuse, such as the durability after 3 years and the durability after 5 years. Although the analysis data  164  is generated for each owner count in the second embodiment, the analysis data  164  may be generated for each owner to generate and provide the provision data. 
     Third Embodiment 
     Next, a third embodiment will be described. An information processing system  1  of the third embodiment provides information about the performance of a battery  40  at the time of reuse such as durability after 3 years and durability after 5 years even after the battery  40  is transferred from a vehicle  10  to another vehicle  10 . A data configuration of the third embodiment is mainly different from that of the first embodiment as in the second embodiment and differences from the first embodiment will be mainly described in the third embodiment. 
       FIG. 11  is a diagram showing an example of collected data  172  of the third embodiment. As shown in  FIG. 11 , in the collected data  172  of the third embodiment, in addition to each item of the collected data  152  of the first embodiment shown in  FIG. 3 , a transfer count and the durability at the time of the final transfer are added. A loading history item indicates the number of times the battery  40  has been transferred between vehicles. When the transfer count is “0,” this indicates that a battery  40  of a new product is mounted. When the transfer count is “1,” this indicates that the battery  40  has a history of transfers between two or more vehicles  10  and the vehicle  10  currently equipped with the battery  40  is equipped with a used battery  40 . 
     The item of durability at the time of the final transfer indicates a full charge capacity of the battery  40  when the battery  40  was last transferred between the vehicles  10 . In the collected data  172 , a start date of use of the battery mounted in a current vehicle  10  instead of a start date of use in another vehicle is stored as the item of “use start date.” 
       FIG. 12  is a diagram showing an example of analysis data  174  of the third embodiment. As shown in  FIG. 12 , the analysis data  174  in the third embodiment is also generated as different data for each transfer count for the same type of battery  40 . In  FIG. 12 , the analysis data  174  of a battery “A” is displayed. An analysis unit  120  generates the analysis data  174  for each item of “new product,” “transfer count: 1,” “transfer count: 2,” and the like as data of the battery “A.” Although not shown in  FIG. 12 , analysis data is similarly generated for each transfer count with respect to batteries “B,” “C,” “D,” and the like. 
     The analysis unit  120  generates provision data as in the first embodiment on the basis of the analysis data  174  that has been generated. A provision unit  130  transmits the provision data generated by the analysis unit  120  to a terminal device  300  of a user U and/or a used vehicle sales business server  400  of a used vehicle sales business operator. 
     The information processing device  100  of the first embodiment generates analysis data  154  on the basis of a state of use of the battery  40  in the plurality of vehicles  10  and the like, generates provision data including the durability after 3 years and the durability after 5 years regarding the performance of the battery  40  at the time of reuse of the battery  40  from the analysis data  154 , and transmits the provision data to the user U, the used vehicle sales business operator, and/or the like. Thus, the user U, the used vehicle sales business operator, and/or the like can obtain information about the performance of the battery  40  at the time of reuse, such as the durability after 3 years and the durability after 5 years. The provision data is data for each transfer count of the battery. Thus, it is possible to confirm a difference between the used product and the new product as the battery  40 , a difference in a transfer count when the battery  40  is a used product, and the like. Consequently, it is possible to obtain information to which a difference between the used product and the new product and the like are added with respect to information about the performance of the battery  40  at the time of reuse, such as the durability after 3 years and the durability after 5 years. 
     Also, the information processing device  100  may transmit the durability after 3 years and the durability after 5 years to another device, for example, a communication device of the vehicle  10 . In the vehicle  10 , information about the performance at the time of reuse as shown in  FIG. 8  may be displayed on the display device  60  of the vehicle  10 . The vehicle  10  may display information associated with the collected data  152 . As for the information associated with the collected data  152 , for example, each item of the collected data  152  may be displayed in a text format or the like, or information obtained from each item of the collected data  152  may be displayed in a text format or a format using an icon. 
     When the information associated with the collected data  152  is displayed by the display device  60 , the vehicle  10  may be configured to be able to display the information while switching a display screen to a screen for displaying other information.  FIG. 13  is a diagram showing an example of an image displayed on the display device  60 . For example, the display device  60  displays an image showing traveling information M, the maximum cruising distance F, and SOC information G of the battery  40  as shown on the left side of  FIG. 13 . 
     When the steering switch  90  is operated and a signal is transmitted to the display device  60  while the image on the left side of  FIG. 13  is displayed, use state information within the collected data  152  is displayed in a text format as shown in the image shown on the right side of  FIG. 13 . Also, “SC” in an image shown on the right side of  FIG. 13  denotes the cycle count. When the steering switch  90  is operated and a signal is transmitted to the display device  60  while the image on the right side of  FIG. 13  is displayed, the image shown on the left side of  FIG. 13  is displayed. In this way, the display of the display device  60  may be switched according to an operation on the steering switch  90 . 
     Although the information processing device  100  may provide the user U and/or the used vehicle sales business operator with information about the durability after 3 years and the durability after 5 years as the provision data  156 , other information about the battery  40  may be provided as the provision data  156 . For example, data obtained by statistically summarizing the collected data  152  transmitted by the vehicle  10  may be used as the provision data  156  or data appropriately selected from the data obtained by statistically summarizing the collected data  152  may be used as the provision data  156 . Also, for each item of the collected data  152  and the like, conditionally summarized data or processed data thereof may be used as the provision data  156 . 
     The present invention has been described above using the above embodiments, but the technical scope of the present disclosure is not limited to the scope described in the above embodiments. Those skilled in the art can make various changes or improvements to the above embodiments. It is obvious from the description of the claims that the changes or improvements may be included in the technical scope of the present invention.
