- FIG. 4 is a flowchart showing an operation example of the storage battery control system 100 shown in FIG.
- the user starts using the storage battery pack 110 (S101). Then, for example, detection results of one or more sensors 113 are transmitted to the server 150 via the communication device 112 or the like. Then, the server 150 determines whether or not an abnormality has been detected by one or more sensors 113 (S102). If no abnormality is detected (No in S102), the user continues to use the storage battery pack 110 (S103).
- the information terminal 140 When an abnormality is detected (Yes in S102), the information terminal 140 notifies the user of an abnormality detection message and a confirmation request (S104). For example, in this case, the server 150 notifies the user of an abnormality detection message and a confirmation request via the information terminal 140 .
- the user who received the notification of the confirmation request confirms the state of the abnormality detected in the storage battery pack 110 (S105).

- the server 150 determines whether there is an abnormality leading to failure according to the confirmation result (S107). If it is determined that there is an abnormality leading to a failure (Yes in S107), the information terminal 140 notifies the user of a use stop request (S110). In this case, for example, the server 150 notifies the user of the use stop request via the information terminal 140 .
- the server 150 determines whether or not the number of times of detection is equal to or greater than the threshold (S109). If it is determined that the number of times of detection is equal to or greater than the threshold (Yes in S109), the information terminal 140 also notifies the user of the use stop request (S110). In this case, for example, the server 150 notifies the user of the use stop request via the information terminal 140 .

This restricts the use of storage battery pack 110 .
- the server 150 may register the user in a blacklist and impose a penalty on the user.
- the information terminal 140 notifies the user of thanks (S114). Specifically, in this case, server 150 notifies the user of thanks via information terminal 140 .

Also, in this case, the server 150 may register the user in the cooperator list and give the user an incentive.
- server 150 performs determination processing and the like.
- all or part of the plurality of processes performed by server 150 may be performed by information terminal 140 instead of server 150, or may be performed by controller 114 of storage battery pack 110 or the like.
- the multiple processes shown in FIG. 4 are divided into a first phase, a second phase and a third phase.
- the first phase when an abnormality is detected, the user is notified of a request to confirm the status of the abnormality.
- the second phase when it is determined that there is an abnormality leading to failure based on the confirmation result, a request to stop using is sent to the user.
- the third phase the use of the storage battery pack 110 is restricted when the use of the storage battery pack 110 is continued after the use stop request.
- the second phase if it is determined that there are no abnormalities leading to failure based on the confirmation results, use will continue. However, if the same abnormality detection is repeated a number of times equal to or greater than the threshold, the user is notified of a use stop request.
- the third phase when the use is stopped in accordance with the use stop request, a thank you for cooperation, guidance for new purchase, etc. are performed.
- the storage battery control system 100 counts up the number of times of detection when it is determined that there is no abnormality leading to failure based on the confirmation result in the above operation. However, the storage battery control system 100 may count up the number of detections before notification of the confirmation request and acquisition of the confirmation result are performed. Then, when the number of times of detection is equal to or greater than the threshold, the storage battery control system 100 may notify the user of the use stop request without notifying the confirmation request and obtaining the confirmation result.
- the threshold for the number of detections may be determined individually depending on the type and level of abnormality. For example, the higher the level of anomaly, the smaller value may be applied to the threshold for the number of detections of that anomaly.
- the storage battery control system 100 notifies the user of a confirmation request each time an abnormality is detected in the above operation. However, instead of such processing, the storage battery control system 100 may notify the user of a confirmation request when the number of abnormalities detected is equal to or greater than a threshold.
- the storage battery control system 100 may notify the user of a confirmation request when the number of abnormalities detected is greater than or equal to the first threshold. Then, the storage battery control system 100 may notify the user of the use stop request when the number of times the abnormality is detected is equal to or greater than the second threshold, which is larger than the first threshold.
- a usage suspension request may be notified.
- the use of storage battery pack 110 may be restricted by omitting the notification of the use stop request.

- the storage battery control system 100 notifies the user of the use stop request. However, depending on the content of the question, if the answer is No, the storage battery control system 100 may notify the user of the use stop request. In addition, storage battery control system 100 may notify the user of more detailed questions according to the answers to the questions. Then, the storage battery control system 100 may notify the user of more detailed usage.
