The program may be recorded in a computer-readable recording medium as well as stored in a storage device. Examples of computer-readable recording media include hard disks, flexible disks, CD-ROMs (Compact Disc Read Only Memory), MO (Magneto Optical Disk) discs, and DVD-ROMs (Digital Versatile Disc Read Only Memory). A program executed by the information processing device 4 may be distributed via the communication network 5 .

The server control unit 43 is composed of, for example, a CPU (Central Processing Unit). The server control unit 43 functionally includes a search unit 46 , an evaluation value calculation unit 47 , and a charging performance registration unit 48 .

The search unit 46 has a function of executing search processing in response to a search request for a charging station from the information processing terminal 3 . The search unit 46 has a function of outputting search results. The search request includes, for example, search conditions related to area.

The evaluation value is an index indicating whether or not the charging station is currently chargeable. In other words, the evaluation value represents an evaluation of whether or not the charging station can charge without failure, estimated from past charging performance. The evaluation value calculation unit 47 may be configured, for example, so that the evaluation value can be expressed numerically. In this case, the evaluation value calculation unit 47 may set the evaluation value such that the higher the numerical value of the evaluation value, the higher the possibility of charging. Further, the evaluation value calculation unit 47 may be configured, for example, so that the evaluation value can be represented by the number of asterisks.

The charging performance registration unit 48 has a function of registering the generated charging performance information in the charging performance DB 45 . The charging performance information is the charging performance information shown in FIG. 2B.

Here, the case where the charging record registration unit 48 determines that the electric vehicle 2 has been charged includes, for example, the case where the amount of charge of the battery in the electric vehicle 2 increases beyond a predetermined threshold. In other words, the charging performance registering unit 48 may estimate that the electric vehicle 2 has been charged when the remaining amount of electricity stored in the battery increases beyond a predetermined threshold. Another case where the charging record registration unit 48 determines that the electric vehicle 2 has been charged includes a case where the cruising range of the electric vehicle 2 has increased beyond a predetermined threshold. The reason why the predetermined threshold value is provided is to exclude cases where the headlights are turned off or the air conditioner is turned off, for example. Even when the headlights are turned off or the air conditioner is turned off, the amount of charge and the cruising distance of the electric vehicle 2 may slightly increase. Therefore, the charge record registration unit 48 can eliminate cases where the charge amount and the cruising range increase without charging the battery.

The information processing device 4 may be a single physical device, or may be configured by a system in which a plurality of devices are connected to a network. The information processing device 4 may be configured by, for example, a device in which the information processing device 4 is divided into three functions.

The first server is configured, for example, to exchange vehicle information with the electric vehicle 2 . The second server has, for example, a map DB 44 . The second server has, for example, a function of searching the map DB 44 based on a search request. The third server has, for example, a charging record DB 45 . The third server has a function of registering the charging performance information and calculating the evaluation value of the charging station.

<Operation of information processing system 1>
Next, operations of the information processing system 1 will be described. First, with reference to FIG. 3, the operation of the information processing system 1 when the driver of the electric vehicle 2 uses the information processing terminal 3 to search for a charging station will be described. FIG. 3 is a flowchart showing the flow of processing among the electric vehicle 2, the information processing terminal 3, and the information processing device 4 when searching for a charging station using the information processing terminal 3. As shown in FIG. The steps of the flow chart are denoted by S below. As a premise, the information processing terminal 3 is in a state where the program 35 is running.

- Search for charging stations The information processing terminal 3 receives a search instruction for charging stations based on the input of search conditions by the driver of the electric vehicle 2 (S1). Upon receiving the charging station search instruction, information processing terminal 3 transmits a search request including search conditions to information processing device 4 (S2). A search condition is, for example, a condition related to an area. The condition regarding the region is, for example, the region where the driver wants the battery of the electric vehicle 2 to be charged. Specifically, the conditions regarding the area include a predetermined range from the position designated by the driver using the terminal input unit 32 of the information processing terminal 3 . The area condition may be a predetermined range from the current position of the electric vehicle 2 or the information processing terminal 3 .

Upon receiving the search request from information processing terminal 3, information processing device 4 executes charging station search processing based on the search conditions (S3).

Here, the charging station search processing will be described with reference to FIG. FIG. 4 is a flowchart showing in more detail the flow of the charging station search process in S3 of FIG.

First, the information processing device 4 acquires charging station information that matches the search condition from the map DB 44 based on the search condition (S11). For example, if the search condition is region A, charging station information of charging stations existing in region A is acquired from the map DB 44 . The charging station information includes information on the longitude and latitude of the charging station.

Further, the charging station information may include, for example, operating information, full/empty information, connector information, and business information as additional information added to the longitude and latitude. The operational information indicates, for example, whether the charging station is out of service or out of order. The fullness information indicates, for example, whether the charging station is full or empty. The connector information indicates, for example, the type of connector adopted by the charging station to electrically and mechanically connect the electric vehicle with the charging station. The business information indicates, for example, the business hours of the charging station or the business hours of the charging station. Here, if the charging station information includes additional information, the charging station and the additional information are associated and stored in advance in the map DB 44 .

Next, the information processing device 4 acquires the charging performance information corresponding to the evaluation period from the charging performance DB 45 (S12). An evaluation period is a period during which an evaluation value is calculated. For example, if the evaluation period is the period from the present to the past three months, the information processing device 4 selects only the charging performance information whose registration date and time is from the present to the period from the present to the past three months. Acquired as charge performance information. The information processing device 4 can handle information with a higher degree of reliability as the registration date and time are closer to the current date and time. The information processing device 4 can also consider that the closer the registration date and time is to the current date and time, the higher the reliability of the information, and deal with the establishment of a new charging station and the abolishment of the charging station.

Next, the outline of the process of acquiring the charging performance information corresponding to the evaluation period of S12 will be described with reference to FIG. For example, when the current date and time is 22:00 on July 10, 2020, the information processing device 4 does not acquire charging performance information whose registration date and time is March 2020 and is not included in the past three months. FIG. 5 exemplifies 2020030711 when the registration date and time is March 7, 2020 at 11:11. As shown in FIG. 5, the information processing device 4 excludes the registration date and time 202003071111 as a narrowing down of the evaluation period when the charging performance information for March 2020 is not acquired.

Next, the information processing device 4 further acquires charging performance information corresponding to the evaluation point for each station ID from the charging performance information acquired in S12 (S13). An evaluation point means, for example, within a predetermined range from the position of the charging station stored in the map DB 44 . The predetermined range may be, for example, a rectangular area that is separated from each other by predetermined distances in the north, south, east and west from the position of the charging station stored in the map DB 44 . The predetermined distance is, for example, 50m×50m. The predetermined distance may be, for example, 5m x 5m. In other words, the information processing device 4 acquires, as evaluation target charging stations, only charging performance information in which the position of the charging performance information is within a predetermined range from the position of the charging station to be evaluated. Position information included in the charging performance information may not be accurate. The information processing device 4 can eliminate position information that is estimated to be inaccurate by acquiring the charging performance information corresponding to the evaluation point.

FIG. 6 is a diagram for explaining the outline of the process of acquiring the charging performance information corresponding to the evaluation point in S13. For example, as shown in FIG. 6, when the charging performance information d1 to d4 exists in the vicinity of the charging station to be evaluated, the information processing device 4 selects one of the charging performance information d1 to d4 from the charging station to be evaluated. The actual charging information d1 and the actual charging information d3 within the region R1 within the predetermined range are acquired, and the actual charging information d2 and the actual charging information d4 outside the region R1 are not acquired. Here, the region R1 may have a rectangular shape as illustrated in FIG. 6, but is not limited to a rectangular shape. Region R1 may be, for example, polygonal, elliptical, or circular in shape. When the region R1 is circular, for example, the R1 region may be set to a circular shape with a predetermined radius centered on the position of the electric vehicle 2 whose battery is charged. The information processing device 4 can set, for example, 11 m as the predetermined radius.

By the way, the GNSS module may not be able to accurately detect the position of the electric vehicle 2, for example. Therefore, the information processing device 4 may destabilize the position information recorded as the charging performance information based on the latitude and longitude included in the vehicle information. Further, the information processing device 4 needs to match position information from unstable vehicle information with a uniquely determined charging station.

Therefore, when creating the charging performance information, the information processing device 4 aggregates the positions included in the vehicle information on which the electric vehicle 2 was charged at the charging station into the information on the nearby charging spot points. The information processing device 4 can normalize the positions of the charging stations by aggregating the positions included in the vehicle information into the information of the recent charging spot points in advance. For example, in addition to the positions included in the vehicle information, the information processing device 4 adds the positions of charging stations included in the map DB that are within a predetermined range from the positions included in the vehicle information to the charging record DB. can be aggregated. By normalizing the positions of the charging stations in advance, the information processing device 4 can improve the processing speed by preselecting the data prior to searching for the charging stations. The information processing device 4 contributes to an improvement in processing speed when returning the charging station and the charging performance information corresponding to the charging station in response to a request from the information processing terminal. Further, when normalizing the positions of the charging stations in advance, the information processing device 4 does not need to register vehicle information included in the map DB that does not have a nearby charging station in the charging record DB. As a result, the information processing device 4 can also exclude the home charging facility from being registered in the charging history DB as the charging station.

Next, the information processing device 4 calculates an evaluation value for each station ID based on the charging performance information acquired in S13 (S14). The evaluation value may be, for example, the number of pieces of charging performance information corresponding to the evaluation period and the evaluation point. The evaluation value may be calculated, for example, by performing a predetermined calculation on the number of charging performance information corresponding to the evaluation period and the evaluation point. For example, the evaluation value may be calculated by weighting the newness of the registration date and time of the charging performance information and the distance between the position of the charging performance information and the position of the charging station.

Returning to FIG. 3, the information processing device 4 transmits the search result of the charging station search process to the information processing terminal 3 (S4). The search result of the charging station search process is the charging station information shown in FIG. 2C.

When receiving the search result from the information processing device 4, the information processing terminal 3 displays the search result on the terminal output unit 33 (S5). For example, the charging station information of the charging stations that match the search conditions may be displayed in a list format, or the icons and evaluation values of the charging stations that match the search conditions may be displayed on a map. The icon may be an icon indicating the type of charging standard.

The information processing terminal 3 displays the search results 330 in list format on the terminal output unit 33, for example, as shown in FIG. The list exemplified in FIG. 15 includes information about charging stations found as search results. In addition, in the example of FIG. 15, the evaluation value is represented by the number of asterisks. The information about the charging station includes, for example, charging station evaluation value information, charging station name information, and charging station location information. The location information of the charging station includes, for example, an address or latitude and longitude.

As a method of expressing the evaluation value by the number of asterisks, for example, there is a method of displaying the evaluation value in consideration of the number of past uses.

As for the method of displaying the evaluation value, for example, as shown in FIG. 15, if the charging station at the top has one star, the charging station at the top has one charging record within the past three months. It is shown that. As for the evaluation value display method, for example, if the second charging station from the top does not have a star mark, it indicates that the charging station second from the top has not been charged within the past three months. As for the method of displaying the evaluation value, for example, if the third charging station from the top has two stars, it means that the third charging station from the top has been charged two to five times within the past three months. show. As for the evaluation value display method, for example, if the fourth charging station from the top has three asterisks, it indicates that the fourth charging station from the top has been charged six times or more within the past three months. In other words, the information processing terminal 3 is configured to be categorized by the number of charging performances in a predetermined period and display the evaluation values on the terminal output unit 33 .

In addition, the method of expressing other evaluation values by the number of asterisks is not limited to the case of considering only the number of times of use in the past. For example, the information processing terminal 3 may add a negative evaluation to the evaluation value when the charging time is older than a predetermined time. For example, information processing terminal 3 obtains the number of asterisks based on the number of times of use in the past, and adds one asterisk if the last charging time is more than half a month and less than 1 month ago. The number may be reduced and displayed on the terminal output unit 33 .
