Description

[0001] This application is a divisional application of the invention patent application with the application date of December 10, 2018, application number 201880081560.0, and invention name "Information processing device, information processing system, information processing method and computer program". Technical Field

[0002] One aspect of the present invention relates to an information processing device, an information processing system, an information processing method, and a computer program for presenting information on a power storage element and a power supply-related device. Background Art

[0003] The power storage element is widely used in uninterruptible power supply devices, DC or AC power supply devices included in stabilized power supplies, etc. In addition, the use of the power storage element in large-scale systems that store power generated by renewable energy or existing power generation systems in advance is increasing.

[0004] Maintenance of storage elements has become important in uninterruptible power supply devices, stabilized power supplies, or power generation systems. A technology has been proposed that enables users or maintenance personnel of storage elements to remotely obtain information about the state of charge (SOC) or life prediction of storage elements included in these systems via a server device.

[0005] For example, Patent Document 1 proposes a system that enables an operator to visually recognize information on a predicted value of a degradation rate of an electric storage element remotely via a server device and a network.

[0006] Patent Document 2 discloses a system that notifies a user and an operator of a battery replacement time based on a monitoring program via a service center and a network in order to reliably replace a battery element in an uninterruptible power supply device, and exchanges information by email or the like.

[0011] Problems to be solved by the invention

[0012] As disclosed in Patent Documents 1 and 2, a system for allowing a user or maintenance personnel to remotely grasp the status of a storage element itself or a device using a storage element has been proposed and implemented. However, a system that can comprehensively display various information in a storage element and a power supply-related device has not been implemented so far.

[0013] There are more and more scenarios where energy storage elements such as lead-acid batteries or lithium-ion batteries are used for industrial purposes other than vehicle-mounted purposes (automobile purposes, two-wheeled motor vehicles). For example, energy storage elements are sometimes provided in parallel with solar power generation systems. In this case, the energy storage elements are connected to power conditioners. In large-scale solar power generation systems called super solar, a large number of energy storage elements and power conditioners are installed and used. Even in the case of realizing power peak reduction in factories or large-scale facilities, a large number of energy storage elements and power conditioners are installed and used. Even in railway applications, a large number of energy storage elements and rectifiers as DC or AC power supply devices are installed and used. In previous maintenance support systems, it was not envisioned that many energy storage elements and power supply-related devices would be installed in distributed power supply systems or business entities.

[0014] In the maintenance management of systems including storage elements and power supply-related devices, although it is possible to use the previous maintenance support systems developed independently of the storage elements or power supply-related devices, there is no sense of uniformity in the usage methods and display methods, which makes maintenance management complicated. In parallel with the penetration of IoT (Internet of Things) into society, expectations for the realization of remote monitoring of storage elements and power supply-related devices and the realization of value-added services brought about by it are increasing.

[0015] An object of one aspect of the present invention is to provide an information processing device, an information processing system, an information processing method, and a computer program capable of comprehensively presenting information on a power storage element and a power supply-related device. Summary of the invention

[0016] Means for solving problems

[0017] The information processing device involved in the present disclosure sends information about a storage element and a power supply-related device. The sending of information is performed in response to a request from the outside or as an event. The information processing device comprises: an acquisition unit that acquires information including the state of the storage element or the power supply-related device through communication; a storage processing unit that stores the acquired information in a storage medium in correspondence with information that respectively identifies the storage element and the power supply-related device; and a sending processing unit that sends display information, which is used to display the information stored in the storage medium in a summary according to each system including the storage element and / or the power supply-related device, or each place where the storage element and / or the power supply-related device is installed.

[0018] The range of information on power storage elements and / or power supply-related devices to be collectively displayed (for example, by each factory area, each office, each business location, or each business entity, etc.) can be set manually by an operator or the like, or can be set automatically.

[0019] According to the above structure, information including the status of each storage element and power-related device is collected by the information processing device, and is sent to other devices as display information for displaying in a comprehensive manner according to each system including the storage element and / or power-related device, or each place where the storage element and / or power-related device is installed. In a system where the storage element and the power-related device operate in association with each other, the status of the storage element and the power-related device can be grasped more efficiently by displaying in a comprehensive manner. In addition, by displaying the status of different monitoring objects related to electricity in a comprehensive manner, it becomes easier to perform maintenance (including planned maintenance and preventive maintenance) of the entire system.

[0020] The storage element is preferably a secondary battery such as a lead-acid battery and a lithium-ion battery, or a rechargeable element such as a capacitor. A portion of the storage element to be monitored may also be a non-rechargeable primary battery. Display information for displaying information of different types of storage elements such as lead-acid batteries and lithium-ion batteries in a comprehensive manner may also be sent to the request source. The storage element may be a storage module to which a plurality of storage units are connected, or a storage module group to which a plurality of such storage modules are connected.

[0021] When the power storage element is configured by connecting a plurality of modules including a plurality of power storage cells, the display information may be displayed by associating information in a hierarchical manner based on a connection structure of the power storage elements.

[0022] In the case of a large-scale power storage system, multiple groups (groups) of power storage modules including multiple power storage units are sometimes connected in series, and multiple groups (groups) are further connected in parallel to form power storage elements (domains). By displaying various information including the status of the power storage elements according to their connection structure, it is more efficient to understand which group, module, or unit needs maintenance.

[0023] The display information may include connection information to a communication device provided in the power storage element or the power supply-related device.

[0024] According to the above configuration, connection with the communication device provided in the power storage element and the power supply related device can be provided via the information processing device, and the status of the entire system and the independent status of each device (power storage element and power supply related device) can be appropriately selected remotely.

[0025] The information processing system involved in the present disclosure includes: a plurality of communication devices, which are arranged in the storage element and the power supply-related device; and an information processing device, which can be connected to the plurality of communication devices for communication. The information processing device includes: an acquisition unit, which acquires information including the state of the storage element or the power supply-related device via the communication device; a storage processing unit, which stores the acquired information in a storage medium in correspondence with information that identifies the storage element and the power supply-related device respectively; and a transmission processing unit, which transmits display information according to a request or as an event, and the display information is used to make the information stored in the storage medium be displayed in a comprehensive manner according to each system including the storage element and / or the power supply-related device, or each place where the storage element and / or the power supply-related device is installed.

[0026] The information processing method disclosed in the present disclosure is to send information of a storage element and a power supply-related device by an information processing device according to a request or as an event. Specifically, using a plurality of communication devices provided in the storage element or the power supply-related device, information including the state of the storage element or the power supply-related device is acquired through communication, the acquired information is stored in a storage medium in correspondence with information that respectively identifies the storage element and the power supply-related device, and display information is sent, the display information being used to display the information stored in the storage medium in a summary according to each system including the storage element and / or the power supply-related device, or each place where the storage element and / or the power supply-related device is provided.

[0027] The computer program involved in the present disclosure causes a computer having a display unit to display information of a storage element and a power supply-related device. The computer program causes the computer to execute a step of requesting information of the storage element and the power supply-related device for each system including the storage element and / or the power supply-related device, or for each location where the storage element and / or the power supply-related device is installed, and to execute a step of collectively displaying information sent in response to the request for each of the systems or each location.

[0028] The power supply-related device may be at least one or more of an uninterruptible power supply device, a so-called power conditioner (inverter) that converts DC to AC (or reverses it), and a rectifier that converts AC to DC or AC with different characteristics. The power supply-related device is preferably electrically connected to the storage element. A large-scale power storage system includes multiple storage elements and power conditioners, and sometimes also includes a rectifier. The information of these storage elements and power supply-related devices can be displayed in a comprehensive manner according to each system or each place (building, administrator, etc.) where the device is installed.

[0053] The present invention will be described in detail with reference to the accompanying drawings showing embodiments thereof.

[0054] (Implementation method 1)

[0055] Figure 1 as well as Figure 21 is a diagram showing an overview of a monitoring system 100 according to the present embodiment. The monitoring system 100 includes: a communication device 1 mounted / connected to a system or device to be monitored; a server device 2 (information processing device) that collects information from the communication device 1; and a client device 3 that acquires the collected information. The server device 2 includes a Web server function, and displays information obtained by the communication device 1 mounted / connected to each device according to access from the client device 3.

[0056] The communication device 1 is mounted on the power storage system 101 which is respectively installed in the wind power generation system, the super solar power generation system S and the thermal power generation system F. In detail, the communication device 1 is respectively mounted on / connected to the power conditioner (PCS) P and the power storage module group L. The power storage module group L is composed of a hierarchical structure of a group formed by connecting a plurality of power storage modules each including a plurality of lithium-ion battery cells in series and a domain formed by connecting a plurality of groups in parallel. A management device M is provided for each of the groups and domains (see Figure 3 ), a communication device 1 is provided in a domain management device M. The power storage system 101 is configured by arranging a plurality of containers C accommodating power storage module groups L in parallel.

[0057] The communication device 1 is also mounted on a device such as an uninterruptible power supply (UPS) U, a rectifier (DC power supply device or AC power supply device) D provided in a stabilized power supply system for railways, or the like.

[0058] In the monitoring system 100 , the communication device 1 is mounted or connected to each power-related device in order for the server device 2 to collect information or for the client device 3 to acquire information. Fig.14 : is a schematic diagram showing an example of the installation of the communication device 1. The communication device 1 can be a terminal device (measurement monitor) that communicates with a battery management unit (BMU) equipped with a storage element to receive information from the storage element, or it can be a network card type device that can be connected to a power supply-related device. The communication device 1 is also installed / connected to the control component of the uninterruptible power supply device U and the rectifier D as a DC power supply device or AC power supply device included in the stabilized power supply system. As described above, in the storage system 101, in order for the communication device 1 to obtain information from the storage module group L, one is provided for each group that brings together multiple storage modules. There are multiple power conditioners P, which are connected to enable serial communication, and the communication device 1 is installed / connected to the control component of any one of the power conditioners P as a representative.

[0059] In the past, when each device has a self-diagnostic function and an abnormality occurs, the power generation of the power generation system S, F, the state of the storage element in the power storage system 101 (SOC, SOH: State Of Health), the state of the UPS, etc. are notified. There is also a situation where each diagnostic function notifies the server device via a connection unit that can realize a remote communication connection, or notifies the user or operator (maintenance personnel) by email or the like. However, these are performed independently of each device. On the other hand, in the monitoring system 100 of the present embodiment, a communication device 1 installed or connected to each device is used for prompting, so that in addition to the information such as the state of the SOC in the power storage system 101 and the detected abnormality, the user or operator can also comprehensively confirm various information including the state of the power supply-related device.

[0060] Figure 2 The communication device 1 shown includes a control unit 10, a storage unit 11, a first communication unit 12, and a second communication unit 13. The control unit 10 is a processor using a CPU (Central Processing Unit), and uses a built-in memory such as a ROM (Read Only Memory) and a RAM (Random Access Memory) to control each component to execute processing.

[0061] The storage unit 11 utilizes a non-volatile memory such as a flash memory. The storage unit 11 stores a device program 1P read out and executed by the control unit 10. The device program 1P includes an embedded OS (Operating System) utilizing Linux (registered trademark), a Web server operating on the OS, and communication programs that comply with SSH (Secure Shell), SNMP (Simple Network Management Protocol), etc. The device program 1P may also include a mail program, and in the event of an abnormality, an email may be automatically sent to a pre-set email address. These programs may also be stored in a memory (ROM) built into the control unit 10. The storage unit 11 stores information such as information collected by the processing of the control unit 10, event logs, etc. The information stored in the storage unit 11 can also be read out via a communication interface such as a USB whose terminal is exposed in the shell of the communication device 1.

[0062] The first communication unit 12 is a communication interface for realizing communication with a device (monitored device) equipped with the communication device 1, and uses, for example, a serial communication interface such as RS-232C or RS-485. For example, each storage module included in the storage module group L may have a built-in control substrate having a communication function conforming to RS-232C, and the first communication unit 12 may communicate with the plurality of storage modules.

[0063] The second communication unit 13 is an interface for realizing communication via the network N, and is a communication interface using, for example, Ethernet (registered trademark) or a wireless communication antenna. The control unit 10 can be communicatively connected to the server device 2 via the second communication unit 13 .

[0064] In the communication device 1 configured in this way, the control unit 10 acquires information obtained by a device equipped with or connected to the communication device 1 via the first communication unit 12. The control unit 10 can also read and execute a Web server program, accept a connection from the server device 2 or the client device 3 as a Web server, and present information. The control unit 10 can accept a shutdown function from a remote location via SSH. The control unit 10 can also read and execute an SNMP program, thereby functioning as an SNMP agent and responding to information requests from the server device 2.

[0065] Figure 3 FIG. 1 is a diagram showing an example of a connection method of the communication device 1. Figure 3 , an example of connection between the communication device 1 and the management device M of the power storage module group L is shown. One management device M is provided for each group numbered (#) 1 to N, and for each domain formed by connecting the groups in parallel. The management device M provided for each group communicates with the control substrate (CMU: Cell Monitoring Unit) with communication function built into each power storage module through serial communication, and performs management processing such as obtaining the status (current, voltage, temperature) of the power storage module and the internal unit, adjusting the balance of each group according to each status, and detecting abnormalities in the communication status. The management device M of the group sends the information of the power storage module of each group to the management device M provided in units of domains. The management device M of the domain collects the information obtained from the management device M of the group belonging to the domain. The communication device 1 can collect this information from the management device M of each domain and provide it to the server device 2 or the client device 3.

[0066] Figure 2 The server device 2 shown is a server computer and includes a control unit 20, a storage unit 21, and a communication unit 22. In the present embodiment, the server device 2 is described as a single server computer, but a configuration in which processing is distributed among a plurality of server computers may be employed.

[0067] The control unit 20 is a processor using a CPU, and uses a built-in memory such as a ROM and RAM to control each component to execute processing. The control unit 20 executes information processing based on the server program 2P stored in the storage unit 21. The server program 2P includes a Web server program, and the control unit 20 functions as a Web server that provides Web pages to the client device 3, accepts login to the Web service, etc. The control unit 20 collects information from the communication device 1 through http / https communication based on the server program 2P.

[0068] The storage unit 21 is a non-volatile memory such as a hard disk or a flash memory. In addition to the server program 2P, the storage unit 21 also stores data including the status of the power conditioner P, the power storage module group L, the uninterruptible power supply device U, and the rectifier D that are monitored and collected by the control unit 20.

[0069] The communication unit 22 is a communication device that realizes communication connection and data transmission and reception via the network N. Specifically, the communication unit 22 is a communication device that supports a dedicated line and a general optical line.

[0070] The client device 3 is a computer used by an operator such as an administrator of the power storage system 101 of the power generation system S, F, an administrator of the stabilized power system, or a maintenance person of the uninterruptible power supply device U. The client device 3 may be a desktop or notebook personal computer, or a so-called smart phone or tablet communication terminal. The client device 3 includes a control unit 30, a storage unit 31, a communication unit 32, a display unit 33, and an operation unit 34.

[0071] The control unit 30 is a processor using a CPU. Based on the web browser program stored in the storage unit 31 , the control unit 30 causes the display unit 33 to display a web page provided by the server device 2 or the communication device 1 .

[0072] The storage unit 31 utilizes a nonvolatile memory such as a hard disk or a flash memory, for example. The storage unit 31 stores various programs including a web browser program.

[0073] The communication unit 32 uses a communication device such as a network card for wired communication to communicate with the base station BS (see Figure 1 ) or a wireless communication device for mobile communication connected to an access point AP. The control unit 30 can communicate with the server device 2 or the communication device 1 via the network N through the communication unit 32 or the communication device 1 to perform communication connection or send and receive information.

[0074] The display unit 33 uses a display such as a liquid crystal display, an organic EL (Electro Luminescence) display, etc. The display unit 33 displays an image of a web page provided by the server device 2 through processing based on a web browser program by the control unit 30. The display unit 33 is preferably a display with a built-in touch panel, but may also be a display without a built-in touch panel.

[0075] The operation unit 34 is a user interface such as a keyboard and a pointing device or a voice input unit that can perform input and output with the control unit 30. The operation unit 34 can also use a touch panel of the display unit 33 or a physical button provided on the housing. The operation unit 34 notifies the control unit 20 of the operation information based on the user.

[0076] like Figure 1 As shown, the network N includes a public communication network N1, which is the so-called Internet, and a carrier network N2 that realizes wireless communication based on a given mobile communication standard. The public communication network N1 includes a general optical line, and the network N also includes a dedicated line to which the server device 2 is connected. The carrier network N2 includes a base station BS, and the client device 3 can communicate with the server device 2 from the base station BS via the network N. An access point AP is connected to the public communication network N1, and the client device 3 can also send and receive information to and from the server device 2 from the access point AP via the network N.

[0077] The monitoring system 100 thus constructed obtains various information including the status of the power conditioner P, the power storage module group L, the uninterruptible power supply device U, and the rectifier D through the server device 2 periodically or according to a request from the client device 3, and stores it in the storage unit 21. In the storage unit 21, the information of the device (P, M, U, D) of the acquisition destination of the identification information and the acquired time information are stored in correspondence. The server device 2 performs processing so that the latest data and its history stored in the storage unit 21 can be obtained from the client device 3 as a web page or data (download). Therefore, the server device 2 can comprehensively present the information obtained from the power storage element or each power supply-related device using the communication device 1 to the client device 3.

[0078] Figure 4This is a flowchart showing an example of the processing procedure of information prompt in the server device 2. The server device 2 obtains information on the detection of abnormalities and information on the status at each time point from the control units of the management device M, power conditioner P, uninterruptible power supply device U and rectifier D configured in the power storage module group L via the communication device 1 that can be connected at a given period, and stores them in the storage unit 21 as data in sequence. In addition, if the control unit 20 of the server device 2 receives a login request from the client device 3, the following processing is started. It is also possible to send a login page as an event to urge the client device 3 to log in at a regular timing or when a change in the system status is detected.

[0079] The control unit 20 as a web server transmits information of a login page for receiving login information from the client device 3 to the client device 3 (step S201). The control unit 20 receives the login information based on the operation of the operation unit 34 on the login screen displayed on the display unit 33 of the client device 3 (step S202).

[0080] Based on the received login information, the control unit 20 extracts the identification information of the system or single device with access rights stored in correspondence with the login information (step S203). The control unit 20 sends the information of the web page that includes the link information to other web pages for displaying the information of each system or device corresponding to the extracted identification information to the client device 3 (step S204). The list of link information included in the web page sent at this time does not distinguish between the power storage module group L, the power conditioner P, the uninterruptible power supply device U, and the rectifier D, and is displayed in units of the system (address) using them. As a result, the state of the power storage module group L, the state of the uninterruptible power supply device U, etc. can be comprehensively confirmed by the operator (maintenance personnel) using the client device 3. In the case where the system or single device with access rights corresponding to the login information is a single one, in step S204, information for displaying the web page about the single system or single device is sent to the client device 3 (S206 or S211).

[0081] The control unit 20 uses the web page displayed by the client device 3 based on the information sent in step S204 to determine whether the link to the system including the power storage module group L is selected (step S205). When it is determined that the link to the system including the power storage module group L is selected (S205: Yes), the control unit 20 sends a web page in which the information of the system is hierarchically organized to the client device 3 (step S206). The hierarchical web page is a page that matches the hierarchical structure of the power storage module group L, and can be selected in the order of domain, group, and power storage module, for example, and the lower layer can be selected according to the selection. The hierarchical structure of each system is determined by the link method of the device provided with the communication device 1. These display examples are described in detail through the screen examples described later.

[0082] The control unit 20 accepts the selection of detailed information of the storage module unit or the layer corresponding to the management device M contained in the system in the web page containing the information of the system of the storage module group L (step S207). If the detailed information is selected, the control unit 20 sends the web page showing the state (structure, total voltage, SOC, temperature, etc.) in the layer to the client device 3 as detailed information (step S208). In step S208, as other detailed information, the link information to the web server of the communication device 1 of the corresponding layer can also be sent to the client device 3 (S208). The web page that prompts the information that can be obtained by the device equipped with / connected to the communication device 1 as described above can be obtained from the web server of the communication device 1.

[0083] Then, the control unit 20 determines whether a logout or end operation of the web browser has been performed by the client device 3 (step S209 ), and ends the process when it is determined that the operation has been performed ( S209 : Yes).

[0084] If it is determined that the logout or the end operation of the web browser has not been performed (S209: No), the control unit 20 determines whether an instruction to transfer to another page has been accepted (step S210). If it is determined that an instruction to transfer to another page has been accepted (S210: Yes), the control unit 20 returns the process to step S205, and sends a page of another system according to the operation from the web browser. If it is determined that an instruction to transfer to another page has not been accepted (S210: No), the control unit 20 returns the process to step S207. While the selection of detailed information is not accepted, the state of the web page displaying the information of the system including the power storage module group L is maintained unchanged.

[0085] At this time, other pages of the transfer destination may also include log information and statistical information processed and stored in correspondence with each system, and links to web pages for predicting the life of the power storage modules included in the output system. In addition, management pages such as editing of login information and editing of devices included in the system may also be included.

[0086] When it is determined in step S205 that the link to the system including the power storage module group L is not selected (S205: No), the control unit 20 sends information of a web page for displaying information of a system using any one or more of the power conditioner P, the uninterruptible power supply device U, or the rectifier D to the client device 3 (step S211).

[0087] The control unit 20 accepts selection of detailed information for any one or more of the power conditioner P, the uninterruptible power supply device U, or the rectifier D included in the selected system (step S212). The control unit 20 sends a web page showing the status (parameters such as structure, current value, voltage value, etc.) of the selected device to the client device 3 (step S213), and advances the processing to step S209. In step S213, as other detailed information, link information to the web server of the communication device 1 corresponding to the selected system or device may also be sent to the client device 3 (S213). After the processing of step S213, if it is determined in step S210 that the instruction to transfer to other pages is not accepted (S210: No), the control unit 20 returns the processing to step S212. During the period in step S212 when the selection of detailed information is not accepted, the state of the web page displaying the information of the selected system is maintained unchanged.

When "New Registration" is selected, a page for accepting new registration of login information, new registration of a system containing the storage module group L, or a power supply-related device is displayed. When "Edit" is selected, a page for accepting the editing of already registered login information, or the editing of information about an already registered system or device is displayed.

[0090] Furthermore, the web screen 330 includes a button 332 for logging out or ending the operation.

[0091] Next, a screen example when a system is selected will be described. Figure 6 This is a diagram showing an example of a screen that collectively displays power storage elements and power supply-related devices for each system. Figure 6 An example of a screen displayed in step S206 is shown. Specifically, for example, when the "XY City Super Solar System" using a plurality of power storage module groups L and power conditioners P is selected by operating the operating unit 34 of the client device 3, Figure 5 The displayed Web screen 330 is displayed on the display unit 33. Figure 6 In the example of the screen, the names of two power conditioners P and the storage module groups L formed into a plurality of groups are shown in accordance with the system structure of the storage system 101 used by the "XY City Super Solar System". For the storage module groups L, a "+" icon 333 for expanding the hierarchical structure, an icon 334 for displaying the detailed information of each, and an icon 335 for displaying the detailed information (real time) are arranged. For the device equipped with the communication device 1, the icon 335 is arranged together with the identification information of the device.

[0092] like Figure 6As shown, the web screen 330 collectively displayed for each selected system includes a menu icon 338 for the selected system. The menu icon 338 includes, for example, menus for "abnormal history", "statistical information", "life prediction", and "device list". When the menu icon "abnormal history" is selected by operating the operation unit 34 of the client device 3, the abnormality or warning (warning) log detected in the power storage module group L and the power supply-related device included in the entire target system is collectively displayed. When "statistical information" is selected, a graph of statistical information (voltage, current, temperature, etc.) about the entire target system is collectively displayed. When "life prediction" is selected, an interface for obtaining the result of the life prediction for the entire system or each power storage module group L included in the system is displayed. "Life prediction" will be described in detail later. When "device list" is selected, a list of devices is displayed for the power conditioner P, the power storage module group L, and the management device M mounted on the power storage module group L included in the system. Detailed information such as the type and model can be included in the list of devices.

Figure 6 The displayed page provides an overview of the structure and shows the status of the individual devices (detailed information).

[0094] Figure 7 This is a diagram showing another example of a screen that displays the storage elements and power supply-related devices in a comprehensive manner for each system. Figure 6 In the case of the icon 333 of detailed information about the power storage module group L, the display Figure 7 The storage system 101 of the "XY City Super Solar System" has a storage module group L with the following structure, that is, it has a plurality of groups connected in parallel with a plurality of domains, and the group has a plurality of modules each including n (n is a natural number. In this embodiment, it is 12) units connected in series. Accordingly, Figure 7 As shown, if a domain is selected, the list corresponding to the group belonging to the domain is expanded, and if a group is selected, the list of the power storage modules belonging to the group is expanded. Each power storage module includes n cells, and if a power storage module is selected on the screen 330 by operating the operating unit 34 of the client device 3, the list (image) of the cells included in the module is expanded.

[0095] exist Figure 7 In the example of the expansion of the hierarchical structure of the power storage module group L, the icon 335 is arranged only in the layer corresponding to the management device M equipped with / connected with the communication device 1 (in Figure 7The configuration of icon 335 is not limited to Figure 7 When the communication devices 1 are connected in a hierarchical structure for each group, the icons 335 may be arranged corresponding to each group.

[0096] Figure 8 It is a diagram showing a display example of detailed information. Figure 8 It is chosen Figure 7 This is an example of a page displayed when the hierarchical icon 334 corresponding to the domain of the power storage module group L in FIG. Figure 8 In the web screen 330, as "domain information", the state of the domain (normal / abnormal), the number of groups included in the domain (total number of groups), the number of groups operating among all groups (number of operating groups), and the distribution (maximum value, average value, and minimum value) of the total voltage, current, cell voltage, SOC, and temperature of the domain are displayed. The "data date and time" of the "domain information" acquired by the server device 2 via the communication device 1 is also displayed on the web screen 330 of the display unit 33. The "domain information" includes links to detailed information of the groups included in the domain, and the number of links corresponds to the number of groups.

[0097] Fig. 9 It is a diagram showing a display example of detailed information. Fig. 9 It is chosen Figure 7 An example of a page displayed when the hierarchical icon 334 corresponding to the group in is displayed. Figure 8 This page is also displayed when you select a link to the group's detailed information in . Fig. 9 In the web screen 330, as "group information", the state of the group (normal / abnormal), the number of modules included in the group (number of modules), the total voltage, current value and SOC of the group, and the voltage and temperature distribution of the cells included in the group are displayed. The "data date and time" of the "group information" acquired by the server device 2 via the communication device 1 is also displayed on the web screen 330 in the display unit 33. The "group information" includes links to detailed information of the power storage modules included in the group, and the number of links corresponds to the number of modules.

[0098] Fig.10 It is a diagram showing a display example of detailed information. Fig.10 It is chosen Figure 7 An example of a page displayed when the hierarchical icon 334 corresponding to the module in the Fig. 9 This page is also displayed when a link to detailed information of a module is selected by operating the operating unit 34 of the client device 3. Fig.10 In FIG. 1 , as “module information”, the voltage of each cell included in the power storage module and the outputs of the temperature sensors provided in the two cell groups are displayed.

[0099] Figures 7 to 10 The screen of each layer page of the storage module group L displayed in the example is shown. For example, when there is no domain information and the storage module group L is composed of a plurality of parallel groups, the highest level layer is displayed as a group. If the storage module group L is only one group, that is, composed of, for example, 16 storage modules connected in series, only the module information obtained from the corresponding communication device 1 is displayed ( Fig.10 ).

[0100] Fig.11 It is a diagram showing a display example of detailed information. Fig.11 It is chosen Figure 6 The screen displayed in the case of the hierarchical icon 335 corresponding to the domain in the Figure 3 The example of the web screen 336 provided by the web server of the communication device 1 mounted on / connected to the management device M shown in FIG. Fig.11 The web screen 336 shown in FIG. 10 requires logging into the web server. The login information at this time is preferably set to Figure 5 The login information of the Web server provided by the server device 2 is automatically logged in without re-entering the login information. Fig.11 page.

[0101] exist Fig.11 In the example shown, the communication device 1 directly provides the client device 3 with information obtained from the control substrate mounted on each power storage module via the management device M respectively provided in the group belonging to the domain through the web screen 336. For example, when an abnormality is detected, the content of the abnormality or the abnormal location is displayed through text information (error code) or images such as color, animation, and schematic diagram. The information provided from the communication device 1 through the web screen 336 is basically the latest information at that time, and is distinguished from the data stored in the storage unit 21 of the server device 2.

[0102] The web screen 336 displayed by the web server function of the communication device 1 preferably includes a plurality of menu icons 337 for executing processing to the management device M or the control substrate via the communication device 1. The plurality of menu icons 337 include, for example, a menu for displaying various information including the above-mentioned abnormal information obtained via the communication device 1, a menu for setting the time and email address for notification to the communication device 1, or a menu for restarting (shutting down). The menu icons 337 may also include a setting menu for remote operation limited to maintenance personnel with authority, a setting menu for the interval of logs, etc.

[0103] Fig.11The Web screen 336 provided by the communication device 1 mounted on the management apparatus M provided in the power storage module group L is taken as an example. However, the same Web screen may be provided by the communication device 1 mounted on the power conditioner P, the uninterruptible power supply apparatus U, and the rectifier D.

[0104] In this way, as a network card type, the communication device 1 that can be mounted not only on the power storage module but also on the power conditioner P, the uninterruptible power supply device U, and the rectifier D is used to collect information of each device to the server device 2. In this way, not only can the independent device be connected via the communication device 1, but also the client device 3 can obtain the information of each power storage module and power supply-related device from the server device 2 in units of systems or addresses including them.

[0105] The processing when the menu for life prediction of the power storage system 101 is selected will be described. Fig.12 This is a diagram showing an example of a screen for accepting a request for life prediction. Fig.12 It is chosen Figure 6 The screen displayed when selecting "Life Prediction" from the menu icon 338 in the menu. Fig.12 In the screen 330, an icon 339 for accepting a request for re-life prediction, an icon 340 for accepting a request for extracting a load pattern, and a display box 341 indicating the date and status of the acceptance request are displayed. In the server device 2, as described above, information (voltage, current, and temperature) is regularly collected from the power storage module group L. The server device 2 has a function of performing life prediction / estimation as a system based on the collected information. When the icon 339 for accepting a request for life prediction is selected, the control unit 20 of the server device 2 detects the selection and performs the calculation (simulation) of the life prediction. Although the calculation can be performed in the server device 2, it can also be performed in a decentralized manner by a dedicated device different from the server device 2, or by a dedicated device group. The more information is collected, the longer the time required for the calculation (simulation) of the life prediction, for example, it may take 1 to 2 hours. Fig.12When the life prediction calculation is started, the screen 330 shown displays the date and time of the acceptance of the request and the text of the calculation status in the display frame 341, and can be transferred to other pages. As described above, the calculation takes time, so it is possible to avoid the situation where the screen 330 is fixed in the acceptance screen of the life prediction during execution and other functions cannot be used during this period. If the life prediction calculation is completed, the server device 2 displays the text "Complete" indicating the date and time of the end of the calculation and the status in the display frame 341 of the screen displayed when "Life Prediction" in the menu icon 338 is selected, and displays an icon for downloading the file of the calculation result. If the icon is selected through the operation unit 34 of the client device 3, the file of the calculation result is sent to the client device 3 via the Web browser. If the life prediction calculation is completed, the server device 2 notifies the completion of the calculation to the pre-stored email address. The intermediate process can also be notified by email. The file of the calculation result of the life prediction can also be attached to the email.

[0106] Fig.13 1 is a diagram showing an example of the content of data obtained by life prediction. Fig.13 For example, the data shown includes the data of the degradation behavior of the storage element after a given period (e.g., 10 years) from the start of use, and the data of the simulation results of the charge and discharge behavior (power, temperature, voltage, current) in a given period. In addition, the data obtained by the life prediction includes the transition of the numerical values ​​of the associated parameters during the period as a simulation result, and the detailed analysis results. In this way, the results of the life prediction of each system based on the information collected by the server device 2 can be obtained from the Web screen displayed comprehensively. In the life prediction calculation, other functions will not be stopped, and the results with good accuracy can be obtained by calculating the actual results data over a long period.

[0107] The example in which the power storage module and the power storage module group L are formed of a plurality of lithium-ion battery cells has been described. Alternatively, the power storage module and the power storage module group L (or a part thereof) may be formed of a plurality of lead storage batteries or capacitors.

[0108] The power conditioner P may be equipped with a storage element (lithium ion battery or lead storage battery) and a management device M in addition to the communication device 1, and may transmit display information for collectively displaying information on the power conditioner P and information on the storage element.

[0109] The uninterruptible power supply U may be equipped with a storage element (lithium ion battery or lead storage battery) and a management device M in addition to the communication device 1, and may transmit display information for collectively displaying the information of the uninterruptible power supply U and the information of the storage element.

[0110] The rectifier D may be equipped with a storage element (lithium ion battery or lead storage battery) and a management device M in addition to the communication device 1, and may transmit display information for collectively displaying the information of the rectifier D and the information of the storage element.

[0111] As another embodiment, the following structure can also be implemented. A computer program is a computer program that causes a computer having a display unit to display information of a storage element, causing the computer to execute: a step of requesting information of the storage element; and a step of establishing a correspondence between the information in a hierarchical manner based on the connection structure of the storage element sent according to the request. According to this structure, the display unit of the computer can be changed from Figure 6 The display transfer shown is Figure 7 The computer program may also be configured to cause the display unit of the computer to change from Figure 7 The display transfer shown is Figure 8 , Fig. 9 or Fig.10 The computer program can be executed by the server device 2 or the client device 3. In addition to the overall (domain level) status of a large-scale power storage system including a large number of power storage units, the status of the group level, module level, and unit level can also be easily grasped.

[0112] The storage element, power conditioner P, uninterruptible power supply device U, and rectifier D are all monitored objects in the monitoring system 100. The number of storage units of the storage element is much larger than that of the power supply-related devices. Therefore, the storage element preferably displays information in a hierarchical manner (fractured) such as domain level, group level, module level, and unit level. In the high-level hierarchy (for example, domain level) of the storage element, it is preferred to display information in a hierarchical manner such as Figure 6 The power storage element and the power supply-related device are displayed in the same layer, so that the state of the entire system including the power storage element and the power supply-related device can be intuitively understood.

[0113] The above-described embodiments are illustrative in all aspects and are not restrictive. Other embodiments will be described below.

[0114] (Implementation method 2)

[0115] The information processing system involved in the present disclosure includes: a plurality of communication devices connected to a storage element and a power supply-related device; and an information processing device that sends and receives information to and from the plurality of communication devices. Each of the plurality of communication devices includes: a first sending unit that, when receiving a sending request from the information processing device, sends information including a state obtained from the connected storage element or power supply-related device to the information processing device; a storage unit that stores screen data for screen display, the screen data for screen display having a common part that is common regardless of the type of the connected storage element or power supply-related device, and an independent part that is different according to the type; a creation unit that, when receiving a connection request, creates display information for causing the request source to display a screen based on the screen data; and a second sending unit that sends the created display information to the request source.

[0116] According to the above structure, various information including the status of the storage element itself or the power-related device can be independently presented by the communication devices respectively provided in the storage element and the power-related device. The presented information includes common parts, but the object is the storage element itself or the power-related device (which device it is), and is displayed in different ways according to its category. Even in a system including a variety of devices, it is easy to visually understand which status information is acquired and displayed.

[0117] Alternatively, the information processing device comprises: a storage unit for storing information sent in response to a sending request to the plurality of communication devices; and a creation unit for creating display information, the display information being used to display a screen including the information stored in the storage unit and connection information to the communication devices, wherein the display information is created by the creation unit when a connection request is received.

[0118] Information including the status of the power storage element itself and the power supply-related device is collected and summarized from each communication device by a specific information processing device, and the information summarized includes connection information to each communication device. Users or maintenance personnel can obtain summary information for each system or each location, and can also obtain independent status information. Based on the information prompted by the information processing device, access to independent information of the power storage element or the power supply-related device is also facilitated.

[0119] The communication device may include an execution unit that executes a Web server program corresponding to a Web browser of the communication terminal device, and the display information may be Web page information.

[0120] The communication devices each have the function of a Web server, providing a Web page to the communication terminal device. The Web page has a common part such as a layout and a background image, and an independent part such as an independent design and material images corresponding to the type of the connected device, and realizing screen transitions.

[0121] The communication device may store a communication program for external linkage that differs depending on the type of the connected power storage element or power supply-related device in the storage unit, and accept a communication connection based on the protocol from the communication terminal device.

[0122] In each communication device, in addition to the common Web server program, an external cooperation program that implements different protocols (message formats) or functions depending on the type of the connected device is also independently stored. The programs stored in the communication device are often common, represented by the Web server program. However, as an independent program, if the device is an uninterruptible power supply device, a program that can accept shutdown control from the outside is stored, and if it is other devices, a communication program that conforms to the abnormal communication protocol of each device is stored.

[0123] The communication device involved in the present disclosure comprises: a first communication unit, which is connected to a storage element or a power supply-related device and communicates with the storage element or the power supply-related device; a second communication unit, which communicates with the first device or the second device; a first sending unit, which, when receiving a sending request from the first device through the second communication unit, sends information including the status of the storage element or the power supply-related device obtained from the first communication unit to the first device; a storage unit, which stores screen data for screen display; and a second sending unit, which, when receiving a connection request from the second device, obtains information including the status of the storage element or the power supply-related device from the first communication unit, creates display information for displaying the acquired information based on the screen data, and sends the created display information from the second communication unit to the second device.

[0124] The information processing method disclosed in the present disclosure processes information respectively through a plurality of communication devices connected to a storage element and a power supply-related device, and an information processing device that transmits and receives information to and from the plurality of communication devices. Specifically, the plurality of communication devices, when receiving a transmission request from the information processing device, transmit information including a state obtained from the connected storage element or power supply-related device to the information processing device, store screen data for screen display having a common portion that is common regardless of the type of the connected storage element or power supply-related device, and an independent portion that is different according to the type, and when receiving a connection request from a communication terminal device, create display information for causing the communication terminal device to display a screen based on the screen data, and send the created display information to the communication terminal device.

[0125] The computer program disclosed herein causes a computer having a display unit to receive and display information about a storage element and a power supply-related device. The computer program causes the computer to execute: a step of requesting a communication connection to a communication device connected to the storage element and the power supply-related device, a step of receiving screen display information having a common portion that is common regardless of the type of the storage element and the power supply-related device and an independent portion that is different according to the type, and a step of displaying a screen corresponding to the type of the storage element and the power supply-related device based on the received screen display information.

[0126] Fig.15 1 is a schematic diagram showing the program structure of the device program 1P stored in the storage unit 11 of the communication device 1. As described above, the device program 1P includes a communication program 12P that complies with SSH and SNMP, in addition to an embedded OS program 10P such as Linux (registered trademark) and a Web server program 11P that operates on the OS. The device program 1P includes these programs as a common part. In addition, the device program 1P includes an independent part that is independently read out depending on which device among the power conditioner P, the management device M, the uninterruptible power supply device U and the rectifier D is connected. The independent part includes a communication program 13P for the communication protocol inherent to each device, Web screen data (including design data, material image data, screen transition information) 14P, and an external collaboration program 15P.

[0127] The communication program 13P includes a protocol for communicating with the target device (serial communication protocol such as RS-232C, RS-485 or USB or other signal input and output) and a program for interpreting signals communicated according to the protocol (status code, etc.). The protocol is unique to each device, can be stored in the storage unit 11 in a table, and can be read out by the communication program 13P.

[0128] The web screen data 14P includes design data, material image data, and screen transition information that are different depending on the device of the object. In the communication device 1 connected to the management device M of the power storage module group L, web screen data 14P for displaying status information such as charging status and error information are stored. In the communication device 1 installed in the power conditioner (PCS) P, web screen data 14P for displaying status information and error information such as charging, discharging, selling electricity, and purchasing electricity are stored. In the communication device 1 installed in the uninterruptible power supply (UPS) U, web screen data 14P for displaying a screen representing status information, error information, and a screen for accepting operations from a remote location are stored. The web screen provided by the communication device 1 of this embodiment has a common color scheme, layout, etc., and the items including images, patterns, or colors contained in the screen are different for each category of the device. The differences in the displayed web screen for each device will be described later.

[0129] For example, the external cooperation program 15P is a client program for cooperation with a power server for the power conditioner P, and is a program for cooperation with an existing shutdown program for the uninterruptible power supply device U. Independent programs may be prepared for the rectifier D and the power storage module group L, or the external cooperation program 15P may not be executed or stored depending on the target device.

[0130] Fig.16 1 is a flowchart showing an example of a process procedure in the communication device 1. The control unit 10 of the communication device 1 starts the following process every time the second communication unit 13 detects a communication event from the server device 2 or the client device 3.

[0131] The control unit 10 determines whether the communication event is a transmission request from the server device 2 (step S101). When it is determined that it is a transmission request from the server device 2 (S101: Yes), the control unit 10 obtains the latest information from the connected device through the first communication unit 12, or reads out the information that has been previously acquired and temporarily stored (step S102). The control unit 10 sends various information such as the acquired status to the server device 2 from the second communication unit 13 (step S103), and the processing ends. Alternatively, the control unit 10 does not receive the transmission request through step S101, and sends the information acquired by the first communication unit 12 according to a pre-set schedule (every 10 minutes, 30 minutes, 1 hour, etc.).

[0132] If it is determined in step S101 that the communication event is not a transmission request from the server device 2 (step S101: No), the communication event is a connection request from the client device 3. The control unit 10 obtains the latest information including the status information from the device connected by the first communication unit 12 (step S104). The control unit 10 creates a web page including the latest information obtained (updates the data included in the web page) (step S105), and sends the data of the created web page from the second communication unit 13 to the client device 3 of the request source (step S106).

[0133] The control unit 10 acquires and updates the operation on the web page in the client device 3 through communication (step S107), and updates the web page according to the operation (step S108). The control unit 10 determines whether a logout or end operation of the web browser is performed by the operation unit 34 of the client device 3 (step S109), and ends the process if it is determined that a logout or end operation is performed (S109: Yes). If it is determined that a logout or end operation is not performed (S109: No), the control unit 10 returns the process to step S107 and continues to accept the operation.

[0134] In the communication device 1, based on the stored screen data 14P, the operation unit 34 of the client device 3 is used to display the screen data on the Web screen 336 ( Fig.11 ), according to the selection operation of various icons such as these menu icons 337, the web screen 336 is transferred. According to the selection of the menu, a display screen of detailed information, an input screen of setting, etc. are displayed.

[0135] Fig.17 1 is a diagram showing an example of a Web screen presented by the communication device 1 . Fig.17 Is choosing Fig.11 An example of a screen displayed when an icon for displaying detailed information is selected from the menu icon 337 of FIG. Fig.17 As shown, the screen 338 is displayed as if it is overlapped with the Web screen 336, and a function for returning to Fig.11Icon 339 of the Web screen 336 of the communication device 1 is displayed. In screen 338, as detailed information, real-time detailed information of the domain corresponding to the management device M connected to the communication device 1 is displayed. The detailed information displays, for example, the number of groups included in the domain (total number of groups), the number of groups working among all groups (number of ON groups), the minimum, average and maximum values ​​of the cell voltage, SOC, total voltage, temperature and current of the domain. In the detailed information, when attention information or abnormality detection results are output by the self-diagnosis function of the control substrate of each management device M or module, it is advisable to display a message indicating the content and the corresponding abnormality code. In screen 338 of detailed information, the status in the hierarchy of groups under the hierarchy of domains is represented by a pattern marked with identification information such as the number of each group. The status can be distinguished and displayed by color, brightness or pattern. If it is Fig.17 In the example of , groups #17 to #20 are not in operation and are therefore displayed in gray, for example. In addition, when a pattern corresponding to each group is selected through the operation unit 34 on the screen 338, a link is given and the screen 338 is switched to display detailed information of the group. It is preferable to include a link to detailed information of each power storage module on the screen displaying the group information.

[0136] Alternatively, a list of event logs may be displayed according to the content of the selected menu, or addresses of the communication device 1 and the management apparatus M, device-specific information, setting information including a set email address for notification, or SNMP connection information may be displayed.

[0137] Fig.18 FIG. 1 is a diagram showing another example of a Web screen presented by the communication device 1 . Fig.18 It shows that when you select Figure 7 The screen displayed when the icon 335 corresponding to the power conditioner (PCS) P in the communication device 1 is displayed is a new web screen 341 provided by the web server of the communication device 1 connected to the power conditioner P. The information displayed by the web screen 341 is based on the web screen data 14P ( Fig.15 ) to output. Also, to display Fig.18 The web screen 341 provided by the communication device 1 is shown as requiring login. The login information at this time is made common with the login to the web server provided by the server device 2, so that the client device 3 automatically logs in and displays without having to input the login information again.
