The control unit 35 controls the operation of the entire terminal device 30.

[0036] 1 again, an example of the functions of an information management system 1 including an information management device 10 according to an embodiment of the present disclosure will be mainly described. In the following, when the first device 20a and the second device 20b are not distinguished from each other, they will be collectively referred to as "device 20."

[0037] The control unit 13 of the information management device 10 acquires identification information of the produced device 20, stores it in the storage unit 12, and automatically registers it in the information management device 10. In the present disclosure, "identification information" includes, for example, account information. The account information is information that the information management device 10 uses to identify whether or not the device 20 is registered in the information management device 10. If the account information is not provided in the information management device 10 in advance, the information management device 10 will not accept access to the information management device 10 from outside.

[0038] The account information is registered in the information management device 10, for example, when a shipping inspection is completed during the manufacture of the device 20. The control unit 13 of the information management device 10 sets the status of information service provision for the account of the device 20 at the time of registration to "invalid" in the information management device 10. When the control unit 13 of the information management device 10 communicates with the device 20 via the communication unit 11 and the dedicated line 50, it sets the status of information service provision for the account of the device 20 to "valid" in the information management device 10.

[0039] The control unit 13 of the information management device 10 receives, via the communication unit 11, basic information transmitted from the device 20 via the dedicated line 50 at predetermined intervals, such as every few minutes to every few tens of minutes. The control unit 13 stores the acquired basic information in the storage unit 12. In the present disclosure, the "basic information" includes, for example, measurement data related to the power of the power storage device 21a included in the first device 20a. The measurement data includes, for example, data on actual measurements such as the amount of charge and discharge of the power storage device 21a. The "basic information" includes, for example, measurement data related to the power of the power generation device 21b included in the second device 20b. The measurement data includes, for example, data on actual measurements such as the amount of power generated by the power generation device 21b.

[0040] In addition, the basic information may further include, for example, information on the state of health (SOH) of the power storage device 21a, and unique information such as serial numbers and setting information such as mode settings for each of the power storage device 21a and the power generation device 21b. The setting information may include, for example, information such as the name of the owner of the power storage device 21a or the power generation device 21b, the installation area, and operation modes such as a VPP (Virtual Power Plant) compatible mode, a self-consumption priority mode, and a solar power generation reverse flow priority mode. The basic information may further include, for example, a record of change history of the setting information.

[0041] The control unit 13 of the information management device 10 generates visualized information related to power based on basic information acquired from the device 20. The control unit 13 stores the generated visualized information in the storage unit 12. In the present disclosure, "visualized information" includes, for example, first information that visualizes the power status, second information that visualizes advice information, and third information that visualizes alert information. The visualized information is intended to provide information to consumers.

[0042] The first information includes, for example, first display screen information of each daily amount of power related to power generation, power sale, power purchase, charging, discharging, and consumption, second display screen information that graphs the transition of each daily amount of power in time series, and third display screen information of power values ​​for each minute on a predetermined date and time, etc. In addition, the first information may include, for example, fourth display screen information that predicts the transition of each amount of power in the next day, fifth display screen information that graphs the degradation state of the power storage device 21a, such as the SOH and estimated remaining years, in time series, and sixth display screen information of the total amount of charging and discharging of the power storage device 21a in one month.

[0043] The second information includes, for example, seventh display screen information for advice on an operation mode suitable for the consumer's usage situation. The seventh display screen information may include, for example, screen information for a notification message such as "Although the mode that prioritizes reverse power flow is set, self-consumption is large, so self-consumption priority mode is more economical."

[0044] The third information may include, for example, eighth display screen information showing, in a list or the like, a history of errors that resulted in shutdown or automatic recovery, and ninth display screen information showing, in a list or the like, a history of discharges to near the set lower limit. The third information may also include, for example, tenth display screen information showing the date and time when the remaining amount of stored electricity is predicted to become insufficient. The third information may also include eleventh display screen information showing, for example, data recording the day when the discharge capacity of the power storage device 21a reached an upper limit (discharge stopped due to insufficient remaining amount), data recording the day when the power storage device 21a was fully charged and could not charge the surplus power generated by the second device 20b (charging stopped due to insufficient remaining amount), the date and time when remote output suppression was implemented for the power generation device 21b, or a record of communication errors.

[0045] A consumer who has registered as a user has the status of information service provision for the account of the device 20 of the information management device 10 set to "enabled," and can access the visualized information stored in the memory unit 12 of the information management device 10, for example, using the terminal device 30. The control unit 35 of the terminal device 30 accesses the information management device 10 in accordance with the consumer's operation related to access using the input unit 33, and causes the display of the output unit 34 to display the visualized information.

[0046] When an access related to visualized information is made to the account of the device 20, the control unit 13 of the information management device 10 resets the countdown to the expiration date of the "enabled" setting of the information service associated with the account and extends the validity period. On the other hand, when the control unit 13 determines that there has been no access from a consumer to at least one of the basic information and the visualized information for a second predetermined period, the control unit 13 changes the setting of the information service associated with the account to "disabled." At this time, the control unit 13 deletes at least a portion of the visualized information stored in the storage unit 12. In the present disclosure, the "second predetermined period" may be set to an appropriate period, such as six months or one year. The second predetermined period may be managed separately for the basic information and the visualized information by the information management device 10. In this case, the second predetermined period may be different for the basic information and the visualized information.

[0047] In the present disclosure, "access" from a consumer to the basic information includes, for example, a request for disclosure of basic information data from the consumer's device 20 to the information management apparatus 10. "Access" from a consumer to the visualized information includes, for example, the consumer's viewing of the visualized information using an apparatus such as the terminal apparatus 30 or the device 20, obtaining the visualized information by downloading it, and requesting its generation.

[0048] The "access" from a consumer to the visualized information is not limited to this and may include, for example, the consumer submitting a consent form regarding the generation of the visualized information. For example, if a consumer fails to submit a consent form regarding the generation of the visualized information for a second predetermined period, the information management device 10 may determine that there is no access from the consumer to the visualized information and delete at least a part of the visualized information. In this case, even if the information management device 10 determines that there is access from the consumer to at least one of the basic information and the visualized information after deleting at least a part of the visualized information, the information management device 10 may not resume the generation of the visualized information unless permission from the consumer is obtained in the consent form.

[0049] In the present disclosure, "enabled" of an information service means, for example, a setting state in which an information service, such as visualized information, is provided to a consumer. "Disabled" of an information service means, for example, a setting state in which an information service, such as visualized information, is not provided to a consumer. "Disabled" may correspond to, for example, a physical state such as erasing a folder in the memory unit 12 in which visualized information is stored as data.

[0050] The control unit 13 of the information management device 10 initially sets the basic information and / or visualized information to "enabled," but changes the setting to "disabled" if it determines that there has been no access from a consumer to at least one of the basic information and / or visualized information for a second predetermined period. At this time, the control unit 13 does not generate visualized information. After changing the setting to "disabled," the control unit 13 may change the setting to "enabled" again if it determines that there has been access from a consumer to at least one of the basic information and / or visualized information. At this time, the control unit 13 may resume generating the visualized information.

[0051] Fig. 3 is a first flowchart for explaining an example of an information management method executed by the information management device 10 of Fig. 1. With reference to Fig. 3, an example of a basic processing flow of the information management method executed by the control unit 13 of the information management device 10 of Fig. 1 will be mainly explained.

[0052] In step S101, the control unit 13 of the information management device 10 acquires the identification information of the device 20. For example, the control unit 13 acquires the identification information of the device 20 at the time when a shipping inspection at the time of manufacturing the device 20 is completed in a factory. The control unit 13 acquires the identification information of the manufactured device 20, stores it in the storage unit 12, and automatically registers it in the information management device 10.

[0053] In step S102, the control unit 13 of the information management apparatus 10 periodically acquires basic information about power from the consumer's device 20. For example, the control unit 13 receives the basic information about power transmitted from the device 20 to the information management apparatus 10 at predetermined intervals, such as every few minutes to every few tens of minutes, from the consumer's device 20 via the dedicated line 50 and the communication unit 11. The control unit 13 stores the acquired basic information in the memory unit 12 in association with the identification information of the device 20 acquired in step S101.

[0054] In step S103, the control unit 13 of the information management device 10 generates visualized information related to power over a first predetermined period based on the basic information acquired in step S102. In the present disclosure, the "first predetermined period" includes convenient periods such as one hour, one day, one week, one month, and one year. The first predetermined period is not limited to these, and may include the entire period. For example, the control unit 13 may generate visualized information based on the basic information over the first predetermined period at predetermined intervals, such as several minutes to several tens of minutes. The control unit 13 stores the generated visualized information in the storage unit 12 in association with the identification information of the device 20 acquired in step S101.

[0055] The control unit 13 may manage the information so that each of the basic information and the visualized information can be identified when storing the basic information and the visualized information in the storage unit 12 in step S102 and step S103, respectively. For example, the control unit 13 may classify each of the basic information and the visualized information into folders.

[0056] The control unit 13 may further subdivide the folder for basic information into folders for each type of basic information, such as measurement data, specific information, and setting information. The control unit 13 may further subdivide the folder for basic information into folders for each first predetermined period. The control unit 13 may further subdivide the folder for visualization information into folders for each type of visualization information, such as first information, second information, and third information. The control unit 13 may further subdivide the folder for visualization information into folders for each first predetermined period.

[0057] By classifying information into folders as described above, the control unit 13 can easily execute processing when deleting at least a portion of the visualized information. If the period of the basic information is separated by the first predetermined period, the control unit 13 can easily execute regeneration of the visualized information and anomaly search, etc. The control unit 13 is not limited to the classification based on folders as described above, and may assign an identifier to each piece of information and classify each of the basic information and visualized information by the identifier.

[0058] In step S104, the control unit 13 of the information management device 10 determines whether or not there has been access from a consumer to at least one of the basic information and the visualized information. If the control unit 13 determines that there has been access, it executes the process of step S105. If the control unit 13 determines that there has been no access from a consumer to at least one of the basic information and the visualized information, it executes the process of step S106.

[0059] In step S105, if it is determined in step S104 that access has occurred, the control unit 13 of the information management device 10 updates the expiration date of the second predetermined period.

[0060] In step S106, if it is determined in step S104 that there is no access, the control unit 13 of the information management device 10 determines whether or not a second predetermined period has elapsed. If it is determined that the second predetermined period has elapsed, the control unit 13 executes the process of step S107. If it is determined that the second predetermined period has not elapsed, the control unit 13 repeats the processes from step S102 onwards.

[0061] In step S107, if the control unit 13 of the information management device 10 determines in steps S104 and S106 that there has been no access from the consumer to at least one of the basic information and the visualized information for the second predetermined period, the control unit 13 deletes at least a part of the visualized information. At this time, the control unit 13 changes the setting of the information service of the device 20 to "disabled."

[0062] For example, the control unit 13 determines that neither access from a consumer to the basic information, which is a request for disclosure of basic information data from the device 20 to the information management device 10 via the dedicated line 50, nor access from a consumer to the visualized information via the network 40 continues for the second predetermined period. At this time, the control unit 13 deletes at least a part of the visualized information from the storage unit 12.

[0063] For example, the control unit 13 determines that a request for disclosure of basic information data is made from the device 20 to the information management apparatus 10 via the dedicated line 50, and that while there is access from a consumer to the basic information, there is no access from the consumer to the visualized information via the network 40 for a second predetermined period. At this time, the control unit 13 deletes at least a part of the visualized information from the storage unit 12.

[0064] For example, the control unit 13 determines that while there is access from a consumer to the visualized information via the network 40, there is no access from the consumer to the basic information for a second predetermined period, in which the device 20 makes a request to the information management apparatus 10 via the dedicated line 50 to disclose data of the basic information. In this case, the control unit 13 deletes at least a part of the visualized information from the storage unit 12.

[0065] In step S107, the control unit 13 may determine information among the visualized information that satisfies a first predetermined condition and delete only the remaining information from the visualized information. In the present disclosure, the "first predetermined condition" includes, for example, a condition that the visualized information has been requested by a consumer within at least a second predetermined period. Without being limited thereto, the first predetermined condition may include, for example, a condition under which it is desirable to retain the visualized information in the visualized information generated based on the basic information even if it is determined that there has been no access to the visualized information within the second predetermined period. The "information that satisfies the first predetermined condition" includes, for example, visualized information that has been requested by a consumer within at least the second predetermined period. Without being limited thereto, the information that satisfies the first predetermined condition may include, for example, highly important information that it is desirable to retain in the visualized information even if it is determined that there has been no access to the visualized information within the second predetermined period.

[0066] For example, the first predetermined condition includes the inclusion of information on insufficient remaining capacity, which is the basis for generating visualized information suggesting a usage method for improving the usage state of the device 20. The first predetermined condition includes the fact that a parameter such as the discharge amount of the power storage device 21a exceeds a limit value. The first predetermined condition includes the fact that error information is transmitted from the power storage device 21a to the information management device 10. The first predetermined condition includes the fact that the condition is specified by a consumer.

[0067] The control unit 13 may determine information that satisfies the first predetermined condition when generating the visualized information in step S103 or when determining that the access has not continued for a second predetermined period in steps S104 and S106. Prior to such a determination process, the control unit 13 may classify the visualized information into information that satisfies the first predetermined condition and other information by folder or identifier.

[0068] For example, the control unit 13 may manage the visualized information that satisfies the first predetermined condition in a folder that is separate from the folder for the basic information and the folder containing only other visualized information. For example, when managing the visualized information together in the same folder, the control unit 13 may manage the visualized information by assigning different identifiers, along with the date and time, to the information that satisfies the first predetermined condition and the other information so that they can be distinguished from each other. Alternatively, the control unit 13 may store and manage the information that satisfies the first predetermined condition in the same folder as the basic information that is not subject to the deletion process, or may manage the information that satisfies the first predetermined condition by assigning the same identifier as the basic information that is not subject to the deletion process.

[0069] Fig. 4 is a second flowchart for explaining an example of an information management method executed by the information management device 10 of Fig. 1. With reference to Fig. 4, an example of the processing flow of the information management method executed by the control unit 13 of the information management device 10 of Fig. 1 following step S107 of Fig. 3 will be mainly explained.

[0070] In step S201, the control unit 13 of the information management device 10 determines whether or not there has been access from a consumer to at least one of the basic information and the visualized information after deleting at least a portion of the visualized information in step S107 of Fig. 3. If the control unit 13 determines that there has been access, it executes the process of step S202. If the control unit 13 determines that there has been no access, it executes the process again from step S201.

[0071] In step S202, the control unit 13 of the information management device 10 resumes generating the visualized information after deleting at least a portion of the visualized information in step S107 of Figure 3 and determining in step S201 that there has been access from a consumer to at least one of the basic information and the visualized information.

[0072] For example, the control unit 13 may generate visualization information based on basic information covering a third predetermined period that satisfies the second predetermined condition. In the present disclosure, the "second predetermined condition" includes, for example, conditions such as being specified by a consumer, having had an error recently, and having had an error in the last few months. As an example, consider a case where the second predetermined condition includes a condition of having had an error in the last few months. In this case, when there is access from a consumer again, the control unit 13 may automatically determine a third predetermined period, such as the past three months, and generate visualization information based on basic information covering the third predetermined period.

[0073] For example, the control unit 13 may select, from among multiple items included in the visualization information, items with high priority that are required by the consumer, and generate the visualization information. The control unit 13 may determine the priority based on the consumer's past browsing history of the visualization information. For example, the control unit 13 may retain, as information, items of past access from the consumer to the visualization information and generation items selected by the consumer before deleting the visualization information, and determine items that are expected to have high priority.

[0074] That is, the control unit 13 may determine the priority based on the browsing history, automatically select items with high priorities, and preferentially generate visualized information related to the selected items. The items may include, for example, each of the first to sixth display screen information items among the first information items included in the visualized information.

[0075] Fig. 5 is a third flowchart for explaining an example of an information management method executed by the information management device 10 of Fig. 1. With reference to Fig. 5, an example of the processing flow of the information management method executed by the control unit 13 of the information management device 10 of Fig. 1 following step S103 of Fig. 3 or step S202 of Fig. 4 will be mainly described.

[0076] In step S301, when visualization information is generated in step S103 of Fig. 3 or step S202 of Fig. 4, the control unit 13 of the information management device 10 determines whether a third predetermined condition is satisfied based on the visualization information. If the control unit 13 determines that the third predetermined condition is satisfied, it executes the process of step S302. If the control unit 13 determines that the third predetermined condition is not satisfied, it executes the process again from step S301.

[0077] In the present disclosure, the "third predetermined condition" includes, for example, a condition under which an alert with added value can be generated based on the generated visualization information. For example, the third predetermined condition includes a condition such as the number of times that the "total amount of charge and discharge per month" for each month over the past six months has exceeded an estimated threshold related to the design life of the power storage device 21a is equal to or greater than a predetermined number of times.

[0078] In step S302, if the control unit 13 of the information management device 10 determines in step S301 that the third predetermined condition is satisfied based on the visualized information, the control unit 13 generates support information related to power. The control unit 13 may transmit the generated support information to at least one of the device 20 and the terminal device 30 via the communication unit 11, and notify the consumer via these devices.

[0079] In the present disclosure, "support information" refers to, for example, information generated based on visualization information, including alert information that provides added value to consumers. The support information may include, for example, specific alert information such as "Your usage is shortening the lifespan of the power storage device 21a," which encourages consumers to voluntarily improve how they use the power storage device 21a. Without being limited to this, the support information may further include, for example, advice information that specifically advises consumers to change the setting of the discharge upper limit value of the power storage device 21a and specifically instructs consumers to improve how they use the power storage device 21a.

[0080] Fig. 6 is a fourth flowchart for explaining an example of an information management method executed by the information management device 10 of Fig. 1. With reference to Fig. 6, an example of the processing flow of the information management method executed by the control unit 13 of the information management device 10 of Fig. 1 following, for example, a determination of "No" in step S106 of Fig. 3 will be mainly described.

[0081] In step S401, the control unit 13 of the information management device 10 determines whether the remaining time of the second predetermined period is below a threshold. If the control unit 13 determines that the remaining time is below the threshold, it executes the process of step S402. If the control unit 13 determines that the remaining time is not below the threshold, it executes the process again from step S401.

[0082] In step S402, if the control unit 13 of the information management device 10 determines in step S401 that the remaining time of the second predetermined period has fallen below the threshold, the control unit 13 generates notification information notifying the consumer that there has been no access to the visualized information. The control unit 13 may transmit the generated notification information to at least one of the device 20 and the terminal device 30 via the communication unit 11, and notify the consumer via these devices.

[0083] Fig. 7 is a first schematic diagram for explaining an example of the operation of the information management device 10 in Fig. 1. Fig. 7 shows how first display screen information generated as visualized information by the control unit 13 of the information management device 10 is displayed on, for example, the display of the output unit 34 of the terminal device 30.

[0084] For example, the control unit 35 of the terminal device 30 may access the information management device 10 and obtain past information on each daily amount of power consumption as first display screen information. For example, the first display screen information includes date and time, weather forecast, and climate information. In addition, each daily amount of power consumption on "** month ** day" specified by the consumer is displayed on the display screen of the output unit 34 of the terminal device 30.

[0085] For example, the screen displays the amount of power generated by solar power generation using the power generation device 21b. The screen displays the amount of power sold and purchased between the electric power company and the customer facility. The screen displays the amount of power consumed at the customer facility. The screen displays the amount of discharge and charge of the power storage device 21a. The screen displays the remaining battery capacity of the power storage device 21a. The screen displays the cumulative amount of power generated by solar power generation using the power generation device 21b.

[0086] Fig. 8 is a second schematic diagram for explaining an example of the operation of the information management device 10 in Fig. 1. Fig. 8 shows how the second display screen information generated as visualized information by the control unit 13 of the information management device 10 is displayed on, for example, the display of the output unit 34 of the terminal device 30.

[0087] For example, the control unit 35 of the terminal device 30 may access the information management device 10 and obtain second display screen information that graphs the transition of each amount of power throughout the day in a time series. For example, the second display screen information includes the amount of power purchased from the power company P1, the amount of power self-consumption P2 of solar power generation using the power generation device 21b, the amount of power sold to the power company P3, the amount of power discharged from the power storage device 21a P4, and the amount of power charged to the power storage device 21a P5. The display screen of the output unit 34 of the terminal device 30 displays the hourly transition of the amount of power purchased P1, the amount of power self-consumption P2, the amount of power sold P3, the amount of power discharged P4, and the amount of power charged P5 over the course of one day in the form of bar graphs.

[0088] Fig. 9 is a third schematic diagram for explaining an example of the operation of the information management device 10 in Fig. 1. Fig. 9 shows a state in which third display screen information generated as visualized information by the control unit 13 of the information management device 10 is displayed on, for example, the display of the output unit 34 of the terminal device 30.

[0089] For example, the control unit 35 of the terminal device 30 may access the information management device 10 to obtain third display screen information of the power value for each minute of a specified date and time. For example, the third display screen information includes items such as the specified date and time, the time, the operation mode, and an error code. In addition, the power data for each period from 15:30 to 15:45 on "September 10, 20xx" specified by the consumer is displayed on the display screen of the output unit 34 of the terminal device 30 as an average Wh for one minute.

[0090] For example, the screen displays the power generated by solar power generation using the power generation device 21b. The screen displays the power sold and purchased between the power company and the customer facility. The screen also displays the charging power and discharging power of the power storage device 21a.

[0091] Fig. 10 is a fourth schematic diagram for explaining an example of the operation of the information management device 10 in Fig. 1. Fig. 10 shows how the eighth display screen information generated as visualized information by the control unit 13 of the information management device 10 is displayed on, for example, the display of the output unit 34 of the terminal device 30.

[0092] For example, the control unit 35 of the terminal device 30 may access the information management device 10 and acquire eighth display screen information that shows a list or the like of a history of errors that resulted in shutdown or automatic recovery. For example, the eighth display screen information includes a number, product type, error content, date and time of occurrence, date and time of recovery, status, and a "Details" button. The error content includes, for example, a power generation shutdown error, a power generation data acquisition error, a power purchase data acquisition error, a charge amount data acquisition error, a discharge amount data acquisition error, and a communication error.

[0093] According to the embodiment described above, it is possible to optimize information management. The information management device 10 generates visualized information related to power over a first predetermined period based on the acquired basic information. This allows the information management device 10 to generate visualized information in advance and prepare for access from users as consumers. The information management device 10 can immediately provide visualized information over a first predetermined period to users. Because the information management device 10 generates visualized information without a user request, it is possible to reduce the time required from when a user accesses the visualized information to when a response is made. The user can immediately check visualized information related to diagnosis, such as when an abnormality occurred in the device 20.

[0094] In addition, when the information management device 10 determines that there has been no access from a consumer to at least one of the basic information and the visualized information for a second predetermined period, it deletes at least a portion of the visualized information. This allows the information management device 10 to perform optimization by deleting less important information from the visualized information related to users who do not use the service. Therefore, the information management device 10 can reduce capital investments, such as expanding the storage capacity of the storage unit 12. The information management device 10 can maintain service provision until the end of production of the device 20 without expanding the storage capacity, and can also reduce the amount of expansion capacity even when expanding the storage capacity.

[0095] After executing the process of deleting at least a portion of the visualized information, the information management device 10 waits for the process of generating the visualized information until a consumer accesses at least one of the basic information and the visualized information, thereby reducing the generation of unused visualized information and reducing the load on the calculation process of the information management device 10 itself. The information management device 10 can optimize information management so that only necessary calculation processes are executed.

[0096] The information management device 10 determines information that satisfies a first predetermined condition from among the visualized information, and deletes only the remaining information from the visualized information. For example, when the information management device 10 analyzes a malfunction of the device 20, the computational process of finding a specific state for all data in the basic information places a heavy load on the information management device 10.

[0097] Therefore, the information management device 10 identifies important information that satisfies a first predetermined condition among the visualized information and deletes only the other information from the visualized information in order to retain the information without deleting it. This allows the information management device 10 to retain important visualized information, such as alert history, and reduce the computational load when analyzing what problems occurred in the past. By retaining important visualized information without deleting it, the information management device 10 can easily determine the location of basic information data at the time of the occurrence of an event related to an alert, even after deleting other visualized information, and can prioritize regeneration of useful visualized information. Therefore, the information management device 10 can also improve the accuracy of necessary computational processing, such as lifespan calculation.

[0098] The information management device 10 determines information that satisfies the first predetermined condition when the visualized information is generated or when it is determined that access does not continue for a second predetermined period. For example, the information management device 10 determines information that satisfies the first predetermined condition when the visualized information is generated. This allows the information management device 10 to determine information that satisfies the first predetermined condition in real time. For example, the information management device 10 determines information that satisfies the first predetermined condition when it is determined that access does not continue for a second predetermined period. This allows the information management device 10 to effectively perform the determination process even when it is not yet possible to determine which item has a high importance at the time the visualized information is generated. For example, even if the information management device 10 generates an alert because the power storage device 21a has reached its discharge upper limit, the information management device 10 may determine that this is an irregular occurrence if it occurs only once, but may determine that if it occurs five times in a row, some kind of problem has occurred and the importance is high.

[0099] After deleting at least a portion of the visualized information, the information management device 10 resumes generating the visualized information when it determines that a consumer has accessed at least one of the basic information and the visualized information. This allows the information management device 10 to meet the needs of consumers who require the visualized information by resuming access. The information management device 10 can also resume generating the visualized information when it is assumed that consumers have resumed access to the basic information, have resumed using the device 20, or have recovered from a failure related to the device 20.

[0100] The information management device 10 generates visualized information based on basic information covering a third predetermined period that satisfies the second predetermined condition. This allows the information management device 10 to efficiently generate visualized information. For example, when the information management device 10 receives access from a consumer again, the information management device 10 automatically determines a third predetermined period, such as the past three months, and generates visualized information based on basic information covering the third predetermined period. In reality, the cause of an abnormality in the device 20 can be roughly determined by tracing back the past three to six months. Therefore, the information management device 10 can first generate visualized information based on data from the third predetermined period, such as the past three months, and then terminate generation of the visualized information once the cause of the abnormality is identified based on the generated visualized information, thereby efficiently performing calculation processing without going further back in time. If the cause of the abnormality is not identified, the information management device 10 can further generate visualized information based on data from the third predetermined period, such as the past three months.

[0101] The information management device 10 generates visualized information by selecting items that are required by consumers and have a high priority from among multiple items included in the visualized information. This allows the information management device 10 to generate visualized information while prioritizing items required by consumers. Therefore, the information management device 10 can omit generating visualized information that will not be used, thereby reducing the load on the calculation process and saving storage capacity of the storage unit 12. Consumers can easily obtain the visualized information they need.

[0102] The information management device 10 determines the priority based on the consumer's past browsing history of visualized information. This allows the information management device 10 to accurately determine the priority. The information management device 10 can also generate visualized information by preferentially selecting items that have been frequently viewed by consumers. The information management device 10 can also omit generating visualized information that is not used, thereby reducing the load on calculation processing and saving storage capacity of the storage unit 12.

[0103] When the information management device 10 determines that the third predetermined condition is satisfied based on the visualized information, it generates support information related to power. This allows the information management device 10 to provide consumers with information that has higher added value than the visualized information. For example, consumers can be motivated to improve how they use the device 20 and can easily understand specific ways to improve. This improves the convenience of consumers when using the information management system 1.

[0104] When the information management device 10 determines that the remaining time of the second predetermined period falls below a threshold, it generates notification information notifying the consumer that there has been no access to the visualized information. This allows the information management device 10 to provide a prior notification before deleting the visualized information, giving the consumer the option of avoiding the risk of losing the visualized information. At this time, the information management device 10 can also allow the consumer to respond as to whether or not to delete the visualized information, and if the consumer determines that the visualized information is unnecessary, the information management device 10 can also delete the visualized information without waiting for the second predetermined period to elapse. Even if there is no response from the consumer, the information management device 10 can also delete the visualized information based on the initial second predetermined period for which it was notified.

[0105] The basic information includes measurement data related to the power of the power storage device 21a included in the device 20. This allows the information management device 10 to receive the measurement data, which is an essential element for generating visualized information, from the power storage device 21a and store it in the storage unit 12.

[0106] Although the present disclosure has been described based on the drawings and embodiments, it should be noted that those skilled in the art can make various modifications and alterations based on the present disclosure. Therefore, it should be noted that these modifications and alterations are included in the scope of the present disclosure. For example, the functions included in each configuration or step can be rearranged so as not to be logically inconsistent, and multiple configurations or steps can be combined or divided into one.

[0107] For example, a general-purpose electronic device such as a smartphone or a computer can be configured to function as the information management device 10 according to the embodiment described above. Specifically, a program describing the processing content for realizing each function of the information management device 10 according to the embodiment is stored in the memory of the electronic device, and the program is read and executed by a processor of the electronic device. Therefore, the present disclosure can also be realized as a program executable by a processor.

[0108] Alternatively, the present disclosure may be realized as a non-transitory computer-readable medium storing a program executable by one or more processors to cause the information management device 10 according to an embodiment to execute each function, etc. It should be understood that these are also encompassed within the scope of the present disclosure.

[0109] For example, at least a part of the processing operations executed in the information management device 10 in the above-described embodiment may be executed in at least one of the device 20 and the terminal device 30. For example, instead of the control unit 13 of the information management device 10, the device 20 or the terminal device 30 may execute the above-described series of processing operations related to the information management device 10. At least a part of the processing operations executed in each of the device 20 and the terminal device 30 may be executed in the information management device 10.

[0110] In the above embodiment, the information management device 10 determines information that satisfies a first predetermined condition from among the visualized information and deletes only information other than the determined information from the visualized information. However, the present invention is not limited to this. The information management device 10 does not have to execute the determination process and the retention process for information that satisfies the first predetermined condition.

[0111] In the above embodiment, the information management device 10 determines information that satisfies the first predetermined condition when the visualized information is generated or when it is determined that access does not extend over the second predetermined period. However, this is not limited to this. The information management device 10 may determine information that satisfies the first predetermined condition at another timing. For example, the information management device 10 may determine information that satisfies the first predetermined condition at any timing between when the visualized information is generated and when it is determined that access does not extend over the second predetermined period.

[0112] In the above embodiment, the information management device 10 resumes generation of the visualized information when it determines that a consumer has accessed at least one of the basic information and the visualized information after deleting at least a part of the visualized information, but this is not limited to this. The information management device 10 does not have to resume generation of the visualized information even if it determines that a consumer has accessed at least one of the basic information and the visualized information after deleting at least a part of the visualized information.

[0113] In the above embodiment, the information management device 10 generates visualization information based on basic information covering a third predetermined period that satisfies the second predetermined condition. However, the present invention is not limited to this. When resuming generation of visualization information, the information management device 10 may generate visualization information based on basic information without specifying a period.

[0114] In the above embodiment, the information management device 10 generates visualized information by selecting, from among multiple items included in the visualized information, items that are required by consumers with high priority. However, the present invention is not limited to this. When resuming generation of visualized information, the information management device 10 may generate visualized information based on basic information without selecting an item.

[0115] In the above embodiment, the information management device 10 automatically determines the priority based on the consumer's past browsing history of visualized information. However, this is not limiting. The information management device 10 may determine high-priority items based on any other information related to the consumer. For example, the information management device 10 may determine high-priority items based on input information from the consumer himself / herself, who specifies high-priority items using the terminal device 30 or the like.

[0116] In the above embodiment, the information management device 10 generates support information related to power when it determines that the third predetermined condition is satisfied based on the visualization information, but this is not limiting. The information management device 10 does not have to generate support information related to power.

[0117] In the above embodiment, when the information management device 10 determines that the remaining time of the second predetermined period has fallen below the threshold, the information management device 10 generates notification information notifying the consumer that there is no access to the visualized information. However, this is not limited to this. The information management device 10 does not have to generate the notification information. Instead of or in addition to the process of generating such notification information, the information management device 10 may generate notification information notifying the consumer that data of past visualized information has been deleted after deleting the visualized information.

[0118] In the above embodiment, the information management system 1 has been described as including the information management apparatus 10, the device 20, and the terminal device 30, but is not limited to this. The information management system 1 may not include the terminal device 30. The device 20 has been described as including the first device 20a and the second device 20b, but is not limited to this. The device 20 may include only one of the first device 20a including the power storage device 21a and the second device 20b including the power generation device 21b. Alternatively, the device 20 may include any other type of device instead of or in addition to the first device 20a including the power storage device 21a and the second device 20b including the power generation device 21b.

[0119] In the above embodiment, it has been described that a consumer who has registered as a user can access the visualized information stored in the storage unit 12 of the information management device 10 using the terminal device 30, but this is not limiting. A consumer who has registered as a user may also be able to access the visualized information stored in the storage unit 12 of the information management device 10 using the device 20 instead of or in addition to the terminal device 30.

[0120] In the above embodiment, the information management device 10 and the terminal device 30 are described as being communicatively connected to each other via the network 40 serving as a public line, but this is not limiting. The information management device 10 and the terminal device 30 may be communicatively connected to each other via a dedicated line 50 of the information management system 1. The information management device 10 and the device 20 are described as being communicatively connected to each other via the dedicated line 50, but this is not limiting. The information management device 10 and the device 20 may be communicatively connected to each other via the network 40 serving as a public line. The device 20 and the terminal device 30 may be communicatively connected to the information management device 10 via different lines as in the above embodiment, or may be communicatively connected to the information management device 10 via the same line, unlike in the above embodiment.
