Electricity storage elements such as lead-acid batteries or lithium-ion batteries are increasingly being applied to industrial applications other than in-vehicle applications (automobile applications, motorcycle applications). For example, a power storage device may be installed side by side in a photovoltaic power generation system. In this case, the storage element is connected to the power conditioner. In a large-scale photovoltaic power generation system called a mega-solar, a very large number of power storage elements and power conditioners are installed and used. A large number of power storage devices and power conditioners are installed and used to achieve power peak shaving in factories or large-scale facilities. Also in railroad applications, a large number of power storage elements and rectifiers, which are DC or AC power supply devices, are installed and used. A conventional maintenance support system does not assume a case where such a large number of power storage elements and power supply-related devices are installed in a distributed power supply system or a business entity.

In parallel with the penetration of IoT (Internet of Things) into society, there are increasing expectations for the realization of remote monitoring of power storage elements and power supply-related devices and the realization of value-added services thereby.

In the maintenance management of a system including storage elements and power supply-related devices, it is important to know when the operation start date at which the storage elements start repeating charging and discharging continuously. Even in a system that uses a large number of power storage elements, the administrator of the facility where the power storage elements are installed or the person in charge of maintenance must accurately record and store the operation start dates of these power storage elements, which is a heavy burden. .

An object of the present invention is to provide an information processing apparatus, an information processing system, an information processing method, and a computer program for automatically recording operation information of a power storage element.

An information processing device is an information processing device that acquires information on a power storage element from a power storage device and/or a power source-related device that includes the power storage device, and has a determination unit that determines whether or not a condition for starting operation of the power storage device is satisfied. a first storage unit that stores the operation start date and time as the first operation start date and time and puts it in a protected state when it is determined that the operation start condition is satisfied; a reception unit that receives a registration request for the operation start date and time; a second storage unit that stores the received operation start date and time as a second operation start date and time when the reception unit receives the registration request.

With the above configuration, the operation start date and time of the storage element is automatically stored based on the operation start conditions. Accurate maintenance management is possible based on the actual operation start date and time even for a system that includes a large number of storage devices. With the above configuration, it is possible for the administrator or the person in charge of maintenance to register the operation start date and time in addition to the operation start date and time automatically stored in a protected state so that they cannot be rewritten in principle. In this case, it is stored as a second operation start date and time different from the first operation start date and time stored in the protected state. To prevent falsification of the operation start date and time while permitting registration of the operation start date and time. Since the correct operation start date and time are automatically stored in a protected state, there is no need to manually input the operation start date and time, and the burden on the operator involved in maintenance can be reduced. In addition to this, since the correct operation start date and time are automatically stored, it is possible to accurately perform maintenance management based on the date when the electric storage element actually started repeating charging and discharging.

An information processing device is an information processing device that acquires information on a power storage element from a power storage device and/or a power source-related device that includes the power storage device, and has a determination unit that determines whether or not a condition for starting operation of the power storage device is satisfied. a storage unit that stores the operation start date and time and puts it in a protected state when it is determined that the operation start condition is satisfied; an acquisition unit that acquires the date of manufacture of the storage element; and the acquired date of manufacture. an alarm judgment unit for judging whether or not alarm conditions are met based on a comparison of the day and the operation start date and time stored in the storage unit; and an alarm unit for issuing an alarm when it is judged that the alarm conditions are met. Prepare.

With the above configuration, if the date of manufacture of the storage element can be acquired, whether or not to issue an alarm may be determined by comparison with the correct operation start date and time stored when the operation start condition is satisfied. Since the storage element deteriorates during a period of non-use, if the storage element starts operating after being completely discharged without being used, it cannot exhibit the performance expected at the time of manufacture. By comparing the date of manufacture of the storage cell with the exact date and time of operation start, if the period of non-use is longer than a predetermined period, a warning will be issued and the usage will be different from the assumed usage. It is possible to inform the person in charge that maintenance cannot be performed. Without recognizing the fact that the equipment has been left unused, it is difficult to carry out proper maintenance. With the above configuration, it is possible to grasp how long it has been since the date of manufacture before the operation was started, so it is possible to perform accurate maintenance management of the storage element.

The operation start condition in the above configuration is a condition that can distinguish between the trial use and the actual operation start. In the first example, the operation start condition is that the continuous operation time after the power storage element or the power-related device is turned on exceeds a predetermined time longer than the preset period required for the pre-shipment test. It is to be.

When the actual operation is started, repetition of charge/discharge of the storage element is continued for a period longer than the period during which most storage elements are charged/discharged in the pre-shipment test. Therefore, whether or not operation has started can be determined by whether or not the system has been operated continuously for a period longer than the period required for pre-shipment testing in most cases. As a result, it is possible to prevent the start of charging and discharging in the pre-shipment test from being erroneously set at the start of operation, and the correct date and time of start of operation are stored.

In a second example of the operation start condition, the operation start condition is that the measurement data for the power storage element is stored for a predetermined period longer than the period required for the pre-shipment test, and the number of times of measurement in the pre-shipment test. It is possible to obtain more than a predetermined number of data, or to obtain data in a predetermined cycle different from the cycle in the pre-shipment test.

When the actual operation is started, the measurement data of the storage element is acquired more times or more frequently over a longer period of time than in the case where most storage elements are charged and discharged in the pre-shipment test. In the case where measurement data is acquired periodically, the acquisition period is longer in the pre-shipment test for most power storage elements than the acquisition period when the actual operation is started. For example, during the test, it is tested whether or not the measurement data can be acquired at the set cycle. This is because it is necessary to acquire data relatively frequently. Therefore, whether or not the operation has started can be determined by whether or not there is a significant difference from the number of acquisitions or the acquisition cycle in the pre-shipment test in most cases. As a result, it is possible to prevent the start of charging and discharging in the pre-shipment test from being erroneously set at the start of operation, and the correct date and time of start of operation are stored.

In the remote monitoring system 100 configured as described above, the server device 2 communicates various information including the states of the power conditioner P, the power storage module group L (management device M), the uninterruptible power supply U, and the rectifier D. It acquires it periodically from the device 1 or in response to a request from the client device 3 and stores it in the storage unit 21 . In the storage unit 21, information for identifying devices (P, M, U, D) from which information is acquired and acquired time information are stored in association with each other. The latest information and its history stored in the storage unit 21 are processed by the server device 2 so that they can be obtained from the client device 3 via a Web page or as data (downloaded). The server device 2 can comprehensively present the information acquired from the power storage element or each power source-related device using the communication device 1 to the client device 3 .

The communication device 1 in the remote monitoring system 100 of the present disclosure automatically records the operation start time for each power storage element such as each power storage module or each power storage cell according to a predetermined operation start condition. FIG. 4 is a flow chart showing an example of a processing procedure by the communication device 1. As shown in FIG. The control unit 10 executes the following processes when the power is turned on.

The control unit 10 determines whether or not there is already a record of the operation start time for the target storage element (step S1). If it is determined that there is no record (S1: NO), the control unit 10 determines the continuous operation time after the devices M, P, U, and D to which the target storage element is connected/mounted are powered on. is started (step S2), and communication by the first communication unit 12 and the second communication unit 13 is started (step S3).

The control unit 10 satisfies the operation start condition using the information obtained by the continuous operation time measurement started in step S2 or the communication by the first communication unit 12 or the second communication unit 13 started in step S3. (step S4). The operation start condition is set so as to be distinguishable from the test execution at the time of manufacture of the communication device 1 . The operation start condition is, for example, that the continuous operation time exceeds a predetermined time. The predetermined time is longer than the test period, such as three days. In another example, the operation start condition is that the first communication unit 12 acquires measurement data for storage cells from the monitoring target devices (M, P, U, D) for a predetermined period, acquires a predetermined number of times, or performs a predetermined period. is to be acquired by The predetermined period is a set value when the measurement data is set to be acquired periodically. The operation start condition may be a combination of these conditions, for example, the continuous operation time exceeds a predetermined time, and measurement data may be obtained for a predetermined period or longer at a predetermined cycle.

If it is determined in step S4 that the operation start condition is satisfied (S4: YES), the control unit 10 specifies the operation start date and time (step S5). The control unit 10 stores the identified operation start date and time in a protected state in association with the identification information of the storage element in the storage unit 11 (step S6), and ends the process. In step S6, the control unit 10 stores the operation start date and time in the storage unit 11, and sets the stored area to the protected state. The control unit 10 may set the area storing the operation start date and time as the non-rewritable area.

If it is determined in step S4 that the operation start condition is not satisfied (S4: NO), the control unit 10 returns the process to step S4 after a predetermined waiting time has elapsed.

If it is determined in step S1 that there is already a record at the start of operation (S1: YES), the control unit 10 terminates the process.

The control unit 10 executes the processing procedure shown in the flowchart of FIG. 4 for each target storage element. As a result, the operation start date and time are automatically stored in the storage unit 11 in association with the identification information of each power storage module or each power storage cell. The communication device 1 transmits the stored operation start date and time in response to a request from the server device 2 or the client device 3 .

Storage devices used in large-scale systems have a relatively long life. It is a heavy burden for the operator or user to accurately record and store the operation start date, which may be referred to several years to ten-odd years after the start of operation. As shown in the flowchart of FIG. 4, by automatically recording the date and time when the conditions for starting operation of the storage element are satisfied, the burden on the operator or user is reduced, and maintenance activities are performed based on accurate information. be able to.

The communication device 1 can accept registration of an operation start date and time by an operator or a user separately from the automatically recorded operation start date and time. FIG. 5 is a flow chart showing an example of a registration procedure by the communication device 1. As shown in FIG.

The communication device 1 receives a registration request for the operation start date and time from the server device 2 or the client device 3 in association with the identification information of the target storage element (step S201). The target power storage elements are power storage elements in domain units, bank units, and module units acquired by the management device M to which the communication device 1 is connected. The target storage element may be a storage module included in the power conditioner P, the uninterruptible power supply U, and the rectifier D on which the communication device 1 is mounted.

The control unit 10 stores the operation start date and time included in the registration request in the storage unit 11 as a second operation start date and time in association with the associated identification information of the storage element (step S202). In this manner, the communication device 1 does not rewrite or overwrite the operation start date and time specified as automatically satisfying the operation start condition. A registration request for the operation start date and time is accepted, but is stored separately as shown in step S202.

Step S201 in the shown processing procedure is executed.

As shown in the flow charts of FIGS. 5 and 6 and FIGS. 7 to 12, when accepting a request for registration of the operation start date from the user or operator and presenting the information of the storage element and the power supply related device, The operation start date related to the registration request can be displayed. A power storage system 101 that takes into consideration the convenience and practicality of the user's or operator's work, while allowing a shift between the operation start date registered by the user or operator and the operation start date that should be specified in terms of the characteristics of the storage element. operation becomes possible.

Since the storage element deteriorates when not in use, it cannot exhibit the performance expected at the time of manufacture if operation is started after the storage element has been completely discharged without being used. If information on the manufacturing date of the storage cell can be obtained, it is possible to issue a warning by comparing it with the automatically recorded operation start date. FIG. 13 is a flow chart showing an example of a processing procedure by the communication device 1. As shown in FIG. The control unit 10 executes the following processes in the power storage system 101 that has started operation.

The control unit 10 of the communication device 1 selects a storage element, which is a target storage module or storage cell, based on the configuration of the storage elements of the connected management device M or the installed devices P, U, and D. (step S401).

The control unit 10 acquires the manufacturing date of the target storage element (step S402). In step S402, the control unit 10 can acquire the date of manufacture from the CMUs incorporated in the power storage modules. The control unit 10 may receive the registration of the date of manufacture of each power storage module, store it in the storage unit 11, and acquire it. The communication device 1 may have the function of an RFID reader and acquire the manufacturing date from the RFID tag attached to the power storage module or the power storage cell.

The control unit 10 reads the operation start date and time of the target storage element from the storage unit 11 (step S403). In step S403, the control unit 10 reads out not the second operation start date and time, but the operation start date and time stored when the operation start condition is satisfied.

The control unit 10 compares the operation start date and time read in step S403 with the manufacturing date and time acquired in step S402 to determine whether or not the alarm conditions are satisfied (step S404). If it is determined in step S404 that the alarm condition is satisfied (S404: YES), the control unit 10 notifies the administrator's email address stored in the server device 2 or the storage unit 11 of the alarm (step S405). ), and it is determined whether or not all target storage elements have been selected (step S406). If it is determined in step S406 that all target power storage elements have been selected (S406: YES), the control unit 10 ends the process.

If it is determined in step S404 that the warning condition is not satisfied (S404: NO), the control unit 10 advances the process to step S406.

When it is determined in step S406 that all the target storage elements have not been selected (S406: NO), the control unit 10 returns the process to step S401.

As shown in the flowchart of FIG. 13, by using the operation start date and time automatically recorded by the communication device 1, it is possible to detect when the power storage element is used in an unexpected manner. It can also issue an alert. When an alarm is notified in step S405, for example, the client device 3 may receive the alarm notification, display the content of the received alarm notification on the display unit 33, and issue an alarm.

In the above-described embodiment, the operation start date and time of the power storage elements of the devices M, P, U, and D to which the communication device 1 is connected/mounted are stored. This processing may be executed by the management device M or may be executed by the server device 2 .

In the above-described embodiment, the operation start date and time automatically recorded based on the operation start conditions are stored in the storage unit 11 in a protected state so that they cannot be rewritten. However, depending on the authority in the remote monitoring system 100, specifically the authority set in the account for logging in to the web server of the communication device 1 or the server device 2, the automatically recorded operation start date and time can be rewritten. may be
