Description

Technical Field

[0001] The present invention relates to an information processing apparatus, an information processing system, an information display apparatus, an information processing method, and a computer program for a power storage element.

Background Art

[0002] The use of power storage elements in large-scale systems that store electric power generated by renewable energy or existing power generation systems is expanding.

[0003] Power storage elements such as lead-acid batteries or lithium-ion batteries are installed in parallel, for example, in solar power generation systems or wind power generation systems. In large-scale power generation systems, a very large number of power storage elements are installed and used. Also, when realizing power peak cutting or energy management in factories or large-scale facilities, a very large number of power storage elements are installed and used.

[0004] Power storage systems composed of power storage elements and power storage systems (ESS: Energy Storage System) including a power conditioner and the like in addition to power storage elements are being installed at many locations. In a system using a power storage element, maintenance activities that support stable operation of the system, including performing state diagnosis of the power storage element, estimating the state of charge (SOC), or predicting the life, are important.

[0005] Regardless of the scale, being able to grasp the situation in a system including a power storage element without the maintenance worker having to go to the site can reduce the work burden and cost burden and improve the quality of maintenance activities. For this reason, a technology (remote monitoring) has been proposed that allows a maintenance worker to acquire information such as the SOC of a power storage element or the state of a power supply-related device via a server device (see Patent Document 1).

[0007] Since energy storage elements are physically located and occupy space, even with remote monitoring, if any abnormality or signs of an abnormality are detected, maintenance personnel will need to go to the site to inspect or replace the equipment. When maintenance personnel go to the site to conduct a detailed investigation, knowing in advance which energy storage elements or power supply-related equipment are installed where and which parts of them need to be checked will reduce the time required for the work and improve work efficiency.

[0008] One aspect of the present invention provides an information processing device, an information processing system, an information display device, an information processing method, and a computer program that improve the work efficiency of maintenance activities for energy storage elements.

[0011] An information processing apparatus according to an embodiment of the present disclosure acquires, by communication, state data indicating the state of a monitoring target device that is a power storage element or a power supply related device, or a system including a plurality of monitoring target devices. The information processing apparatus includes a storage processing unit that stores the acquired state data in a storage medium in association with identification data for identifying the monitoring target device, and a specifying unit that specifies the state of the system or the monitoring target device including the monitoring target device based on the state data stored in the storage medium. The information processing apparatus includes a transmission processing unit that transmits display information for causing a screen to be displayed, the screen including an image of the system or the monitoring target device, a first graphic indicating the specified state of the system or the monitoring target device, and a second graphic indicating from which direction the image of the system or the monitoring target device is viewed.

[0012] The power storage element may be a lithium ion battery (non-aqueous electrolyte secondary battery) or a battery pack thereof. In a lithium ion battery or a battery pack thereof, various states (current, voltage, temperature, state of charge (SOC), etc.) are measured or calculated in a short cycle and acquired by a management device as state data. The power storage element may be another secondary battery, a primary battery, or a capacitor as long as state data can be acquired by the management device.

[0013] The power storage element may be a storage cell, or a storage module in which a plurality of storage cells are connected in series and / or in parallel. The power storage element may be a storage unit (hereinafter, also referred to as a "bank") in which a plurality of storage modules are connected in series. The power storage element may be a storage unit (hereinafter, also referred to as a "domain") in which a plurality of storage modules or banks are connected in parallel.

[0014] The power supply related device may be any of a power conditioner, an uninterruptible power supply, a rectifier, a DC power supply device, a charger for an electric vehicle, or a charge / discharge device.

[0015] The state data to be processed by the information processing apparatus is shown in association with identification data for identifying the system or the monitored device for each system or monitored device, and the state of each system or monitored device is displayed graphically. The system or monitored device is composed of any one or a combination of one or more power storage elements and one or more power supply related devices. When it is one power storage element (power storage module) or one power supply related device (such as an uninterruptible power supply unit alone), it is called a monitored device, and when it is a combination of multiple ones, it is called a system.

[0016] With the above configuration, the maintenance worker can pre-grasp from the displayed graphic which device in the system should be checked and which part of the device should be checked. When the maintenance worker arrives at the site, by comparing the installation state of the power storage element or power supply related device that can be visually recognized with the graphic, it can be easily grasped which part of which device should be checked.

[0017] In the information processing apparatus, the second graphic may be an image indicating whether the image of the system or the monitored device is seen from the top surface or the side surface.

[0018] With the above configuration, the viewer (maintenance worker) of the image can recognize from the second graphic which direction the image of the displayed system or monitored device is seen from. The second graphic may include symbols or texts indicating which direction it is seen from.

[0019] In the information processing apparatus, the screen is hierarchically created based on the hierarchy of the system or the monitored device to be displayed, and the second graphic may show different directions from which the state screen corresponding to one hierarchy and the state screen corresponding to another hierarchy are seen.

[0020] In the above configuration, the status screens displayed according to the hierarchical structure of the system or monitored device are displayed in a hierarchical manner, for example, from the whole to a part, and from a part to a more detailed part. The images of the system or monitored device in the status screens corresponding to each hierarchy may represent the system or monitored device in different orientations depending on the hierarchy.

[0021] With the above configuration, it becomes possible to more accurately identify the location of the target part from the image, depending on the scale of the system or the device being monitored.

[0022] By manipulating the second graphic, it may be possible to transition the image of the system or monitored device from an image showing a view from above to an image showing a view from the right side, and from an image showing a view from the right side to an image showing a view from the front.

[0023] The information processing device may display in the first graphic the state of at least one of the voltage, current, and temperature of a cell, module, bank, or multiple banks of the energy storage element.

[0024] With the above configuration, the viewer can accurately recognize the status of each level in the hierarchical structure of energy storage elements, such as the state of a particular cell or module. When maintenance workers visit the actual location where the energy storage elements are installed, they can easily check the status by comparing the actual installation situation with the displayed graphics, thereby streamlining maintenance work.

[0025] The information processing system is a system including a monitored device which is an energy storage element or a power supply-related device, or a system which includes multiple monitored devices, and includes multiple communication devices mounted on or connected to the monitored device, an information processing device which can communicate with the multiple communication devices, and a client device which has a display unit which can communicate with the information processing device. The information processing device acquires status data indicating the status of the monitored device from the multiple communication devices, stores the acquired status data in a storage medium in association with identification data which identifies the monitored device, identifies the status of the system including the monitored device or the monitored device based on the data stored in the storage medium, and transmits display information for displaying a screen which includes an image of the system or monitored device, a first graphic which indicates the identified status of the system or monitored device, and a second graphic which indicates the direction from which the image of the system or monitored device represents the system or monitored device.

[0026] The information display device comprises a communication unit that connects to an information processing device that acquires status data indicating the status of a monitored device, which is an energy storage element or a power supply-related device, or a system including multiple monitored devices, from multiple communication devices mounted on or connected to the monitored device and stores the data in a storage medium, and a display unit, and displays a screen on the display unit that includes an image of the system or monitored device, a first graphic indicating a specified state of the system or monitored device, and a second graphic indicating from which direction the image of the system or monitored device represents the system or monitored device.

[0027] The screen displayed by the information display device includes an image of the system or the monitored device, a first graphic showing the state of the image of the system or the monitored device, and a second graphic showing the direction from which the image represents the system or the monitored device.

[0028] The information processing method acquires status data indicating the state of a monitored device, which is an energy storage element or a power supply-related device, or a system including multiple monitored devices, by communication; stores the acquired status data in a storage medium in association with identification data that identifies the monitored device; identifies the state of the system including the monitored device or the monitored device based on the status data stored in the storage medium; and transmits display information for displaying a screen that includes an image of the system or monitored device, a first graphic indicating the identified state of the system or monitored device, and a second graphic indicating the direction from which the image of the system or monitored device represents the system or monitored device.

[0029] The computer program causes a computer capable of communicating with a monitored device, which is an energy storage element or a power supply-related device, or a system including multiple monitored devices, to perform a process to obtain status data indicating the status of the monitored device from the monitored device or system via communication, store the obtained status data in a storage medium in association with identification data that identifies the monitored device, identify the status of the system including the monitored device or the monitored device based on the status data stored in the storage medium, and transmit display information to display a screen including an image of the system or monitored device, a first graphic indicating the identified status of the system or monitored device, and a second graphic indicating the direction from which the image of the system or monitored device represents the system or monitored device.

[0030] The computer program causes a computer equipped with a display unit to communicate with an information processing device that acquires status data indicating the status of a monitored device, which is an energy storage element or a power supply-related device, or a system including multiple monitored devices, from multiple communication devices mounted on or connected to the monitored device, and stores the data in a storage medium. Based on the information transmitted from the information processing device, the program causes the computer to execute a process to display on the display unit a screen that includes an image of the system or monitored device, a first graphic indicating a specific state of the system or monitored device, and a second graphic indicating the direction from which the image of the system or monitored device represents the system or monitored device.

[0031] The present invention will be specifically described with reference to the drawings illustrating its embodiments.

[0032] (First Embodiment) Figure 1 shows an overview of the remote monitoring system 100. The remote monitoring system 100 enables remote access to information regarding energy storage elements and power supply-related devices included in the mega solar power generation system S, thermal power generation system F, and wind power generation system W. Rectifiers (DC power supply devices or AC power supply devices) D located in uninterruptible power supply (UPS) U, stabilized power supply systems, etc., may also be remotely monitored.

[0033] A power conditioner (PCS) P and an energy storage system 101 are installed side-by-side in the mega solar power generation system S, the thermal power generation system F, and the wind power generation system W. The energy storage system 101 may be composed of multiple containers C, each containing a group of energy storage modules L, installed side-by-side. In the energy storage system 101, the group of energy storage modules L and the power conditioner P may be located inside a building (energy storage room). The group of energy storage modules L includes multiple energy storage elements. The energy storage elements are preferably rechargeable, such as secondary batteries like lead-acid batteries and lithium-ion batteries, or capacitors. Some of the energy storage elements may be non-rechargeable primary batteries.

[0034] In the remote monitoring system 100, a communication device 1 (see Figure 2) is installed / connected to each of the energy storage systems 101 or power supply-related devices (P, U, D and the management device M described later) in the systems S, F, and W that are to be monitored. The remote monitoring system 100 includes the communication device 1, a server device 2 (information processing device: as described in the claim) that collects information via the communication device 1, a client device 3 for viewing the collected information, and a network N which is a communication medium between the devices.

[0035] The communication device 1 may be a terminal device (measurement monitor) that communicates with a battery management unit (BMU) provided in the energy storage element to receive information about the energy storage element, or it may be an ECHONET / ECHONETLite® compatible controller. The communication device 1 may be an independent device, or it may be a network card type device that can be mounted on a power conditioner P or an energy storage module group L. For example, the communication device 1 is an independent communication device installed to collect measurement data wirelessly from a slave unit that measures the internal resistance, voltage, current, temperature, etc., of an energy storage element, such as a lead-acid battery. For example, the communication device 1 is a network card type device that is incorporated into an energy storage device in which lithium-ion batteries are connected in series and connected to the control board of the energy storage device.

[0036] Communication device 1 is provided for each group of energy storage modules L in the energy storage system 101, with one device for each group of energy storage modules. Multiple power conditioners P are connected to each other via serial communication, and communication device 1 is connected to the control unit of one of the representative power conditioner P units.

[0037] Server device 2 includes a web server function and presents information obtained from communication devices 1 installed on / connected to each monitored device in response to access from client device 3.

[0038] Network N includes a public communication network N1, which is the so-called internet, and a carrier network N2 that implements wireless communication according to a predetermined mobile communication standard. The public communication network N1 includes a general optical line, and Network N may also include a dedicated line to which the server device 2 is connected. The network card N may include an ECHONET / ECHONETLite compatible network. The carrier network N2 includes a base station BS, and if the client device 3 is a communication terminal, the client device 3 can communicate with the server device 2 via Network N from the base station BS. An access point AP is connected to the public communication network N1, and if the client device 3 is a communication terminal, the client device 3 can communicate with the server device 2 via Network N from the access point AP. Communication devices 1 mounted on / connected to the system S,F,W or independent power supply related devices P,U,D can communicate with the server device 2 or client device 3 via Network N through the public communication network N1 from the network laid at the location where the system or power supply related devices P,U,D are installed.

[0039] The energy storage module group L of the energy storage system 101 has a hierarchical structure. The communication device 1, which transmits information about the energy storage elements to the server device 2, obtains information about the energy storage elements included in the energy storage module group L from the management device M provided in the energy storage module group L. Figure 2 shows an example of the hierarchical structure of the energy storage module group L and the connection configuration of the communication device 1. The energy storage module group L is composed of a hierarchical structure of banks, for example, in which multiple energy storage cells (also called cells) are connected in series, and domains, in which multiple banks are connected in parallel.

[0040] In the example in Figure 2, one management device M is provided for each of the banks numbered (#) 1 to N, and also for each domain formed by connecting the banks in parallel. The management device M provided for each bank communicates via serial communication with a control board with communication capabilities (CMU: Cell Monitoring Unit) built into each energy storage module, and acquires measurement data (current, voltage, temperature, internal resistance, etc.) from the energy storage cells inside the energy storage module. The management device M for each bank performs management processing such as detecting voltage anomalies in each cell of the energy storage module. Each bank's management device M transmits the measurement data obtained from the energy storage modules of its respective bank to the management device M provided in the domain. The domain's management device M aggregates the measurement data and detected anomalies obtained from the management devices M of the banks belonging to that domain. In the example in Figure 2, communication device 1 is connected to the domain's management device M. Alternatively, communication device 1 may be connected to both the domain's management device M and the bank's management device M.

[0041] In the remote monitoring system 100, the server device 2 uses communication devices 1 installed on / connected to each device to collect information such as the state of the energy storage system 101, including the SOC and SOH (State of Health), and whether or not there are any abnormalities. Based on the collected status (measurement data), the server device 2 can derive and present algorithms suitable for the energy storage elements included in the energy storage system 101, or the state of the power supply-related devices P, U, D, using algorithms suitable for each system and device.

[0042] Figure 3 is a block diagram showing the internal configuration of the device included in the remote monitoring system 100. As shown in Figure 3, the communication device 1 comprises 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 it uses built-in memory such as ROM (Read Only Memory) and RAM (Random Access Memory) to control each component and execute processing.

[0043] The storage unit 11 uses non-volatile memory such as flash memory. The storage unit 11 stores a device program 1P that the control unit 10 reads and executes. The device program 1P includes a communication program compliant with SSH (Secure Shell), SNMP (Simple Network Management Protocol), etc. The storage unit 11 stores information collected by the processing of the control unit 10. The information stored in the storage unit 11 can also be read via a communication interface such as USB, whose terminals are exposed on the housing of the communication device 1. The device program 1P stored in the storage unit 11 may be a copy of the device program 4P stored in the storage medium 4, read by the control unit 10 and stored in the storage unit 11.

[0044] The first communication unit 12 is a communication interface that enables communication between the communication device 1 and the monitored device to which it is connected. The first communication unit 12 is, for example, a serial communication interface compliant with RS232C or RS485. For example, power supply-related devices such as power conditioners P are equipped with a control unit that has a serial communication function compliant with RS485, and the first communication unit 12 communicates with that control unit. When the control boards provided in the energy storage module group L are connected by a CAN (Controller Area Network) bus and communication between control boards is realized by CAN communication, the first communication unit 12 is a communication interface based on the CAN protocol. The first communication unit 12 may also be a communication interface compliant with the ECHONET / ECHONETLite standard.

[0045] The second communication unit 13 is an interface that enables communication via the network N, and uses a communication interface such as Ethernet® or a wireless communication antenna. The control unit 10 can communicate with the server device 2 via the second communication unit 13. The second communication unit 13 may also be a communication interface that conforms to the ECHONET / ECHONETLite standard.

[0046] In the communication device 1 configured in this way, the control unit 10 acquires measurement data of the energy storage element obtained from the device on which the communication device 1 is mounted / connected, as well as data indicating whether or not there is an abnormality in the equipment, etc., via the first communication unit 12. The control unit 10 may also function as an SNMP agent by reading and executing an SNMP program, and in response to information requests from the server device 2, it may send measurement data to the server device 2, and status data if an abnormality or warning state is detected.

[0047] Server device 2 uses a server computer and includes a control unit 20, a storage unit 21, and a communication unit 22. In the first embodiment, server device 2 is described as a single server computer, but processing may be distributed among multiple server computers.

[0048] The control unit 20 is a processor using a CPU or GPU (Graphics Processing Unit), and it controls each component to execute processing using built-in memory such as ROM and RAM. The control unit 20 performs communication and information processing based on the server program 21P stored in the storage unit 21. The server program 21P includes a web server program. The control unit 20 functions as a web server that provides web pages to the client device 3. Based on the server program 21P, the control unit 20 collects information from the communication device 1 as an SNMP server.

[0049] The storage unit 21 uses non-volatile memory such as a hard disk or flash memory. The storage unit 21 stores the server program 21P and the data processing program 22P described above. The server program P and data processing program 22P stored in the storage unit 21 may be copies of the server program 51P and data processing program 52P stored in the storage medium 5, which are read by the control unit 20 and stored in the storage unit 21.

[0050] The storage unit 21 stores measurement data of the monitored energy storage system 101, power conditioner P, and energy storage module group L, which are collected by the processing of the control unit 20. If the monitored system includes other power-related devices (rectifier D, uninterruptible power supply U, etc.), their measurement data is also stored. The measurement data is associated with identification information (number, symbol) that identifies the system or device. The measurement data of the energy storage module group L is stored according to a hierarchical structure of domain, bank, module, or cell.

[0051] The storage unit 21 stores multiple images for displaying the status of the monitored energy storage module group L or power supply-related devices P, U, D. These multiple images are stored in the storage unit 21 in association with identification information that identifies the monitored energy storage module group L or power supply-related devices P, U, D. The multiple images include images representing the energy storage module group L or power supply-related devices P, U, D.

[0052] The memory unit 21 stores multiple images, including images showing the arrangement of the energy storage module group L or power supply-related devices P, U, D. These images include aerial photographs, satellite photographs, 2D maps, design drawings, CAD drawings, or illustrations. These images may be stored by uploading from the client device 3. For each image, the location or range of the monitored energy storage module group L or power supply-related devices P, U, D is stored, among the photographs, maps, design drawings, drawings, or illustrations. The information indicating the location or range is, for example, coordinate information corresponding to the image. If the image is an aerial photograph, satellite photograph, or map, it may also include latitude and longitude information and information indicating the relative position. Images showing the arrangement are associated with data that identifies whether the image represents a view from above, from the side, or from an oblique angle above. This allows the control unit 20 to determine whether the read image represents a view of the energy storage module group L or power supply-related devices P, U, D from above, from the side, etc., when reading an image.

[0053] The image showing the arrangement of the energy storage module group L or power supply-related devices P, U, D stored in the memory unit 21 includes icons, illustrations, and animations indicating the orientation of the system or device shown in the image. The icons, illustrations, and animations indicating orientation are displayed together with graphics showing the position of the object when the system or device is viewed from that orientation. For example, if the image showing the arrangement represents a view from above, the icons, illustrations, and animations indicating orientation include an arrow symbol image, text, etc., indicating "from above." If the image showing the arrangement represents a view from the front (side), it includes an arrow symbol image, text, etc., indicating "from the front." Similarly, if the image showing the arrangement represents a view from the side (left or right) or from the back, it includes an arrow symbol image, text, etc., indicating "from the side" or "from the back," respectively. The icons, illustrations, and animations indicating orientation may also include diagrams indicating directions. If the image showing the arrangement is in perspective view, the icons, illustrations, and animations indicating orientation may include text or images indicating directions, or arrow symbols indicating directions. This makes it possible to provide a web page that identifies where in the energy storage module group L the energy storage elements are located, where in the system the power supply-related devices P, U, and D are installed, and where in the power supply-related devices P, U, and D a component is located.

[0054] The multiple images stored in the memory unit 21 may include illustrations, icons, animations, and other images that represent the status (abnormal / normal / caution) of the energy storage module group L or the power supply-related devices P, U, D. In addition to images for displaying status and arrangement, the memory unit 21 may also store design data such as style sheets and scripts for visually outputting the status of the energy storage system 101 and the power supply-related devices P, U, D on a web-based basis.

[0055] The communication unit 22 is a device that enables communication connection and transmission / reception of information via the network N. Specifically, the communication unit 22 is a network card compatible with the network N.

[0056] Client device 3 is a computer used by the administrator or maintenance worker of the power generation system S, F, W. Client device 3 may be a desktop or laptop personal computer, or a so-called smartphone or tablet type communication terminal. Client device 3 comprises a control unit 30, a storage unit 31, a communication unit 32, a display unit 33, and an operation unit 34.

[0057] The control unit 30 is a processor using a CPU. Based on the client program 3P stored in the memory unit 31, the control unit 30 displays the web page provided by the server device 2 on the display unit 33. The client program 3P is embedded in the web page provided by the web server function of the server device 2, and includes a script and a web browser program that are temporarily stored in the client device 3, and is a program for displaying a web-based screen based on the operation of the server device 2.

[0058] The storage unit 31 uses non-volatile memory such as a hard disk or flash memory. Various programs, including the client program 3P, are stored in the storage unit 31. The client program 3P may be a copy of the client program 6P stored in the storage medium 6, read by the control unit 30 and stored in the storage unit 31.

[0059] The communication unit 32 uses a network card for wired communication, a wireless communication device for mobile communication connected to a base station BS (see Figure 1), or a wireless communication device compatible with connection to an access point AP (see Figure 1). The control unit 30 can communicate with the server device 2 or the communication devices 1 installed / connected to each device via the network N, or send and receive information, through the communication unit 32.

[0060] The display unit 33 uses a display such as a liquid crystal display or an organic EL (Electro-Luminescence) display. The display unit 33 displays an image of a web page provided by the server device 2 through processing based on the client program 3P of the control unit 30. The display unit 33 may be a display with a built-in touch panel or a display without a built-in touch panel.

[0061] The operation unit 34 is a user interface such as a keyboard and pointing device or an audio input unit that can input and output to and from the control unit 30. The operation unit 34 may use the touch panel of the display unit 33 or physical buttons provided on the housing. The control unit 30 notifies the user of the operation information from the operation unit 34.

[0062] In the remote monitoring system 100 configured in this way, the server device 2 sequentially acquires data, including the status of the system or device to be monitored, from the communication device 1 based on the data processing program 22P, and stores it in the storage unit 21. For the group of energy storage modules L, the storage unit 21 stores measurement data transmitted from the management device M and data indicating detected abnormalities for each energy storage cell or module of the group of energy storage modules L to be monitored. For the power supply-related devices P, U, D, the storage unit 21 sequentially stores data indicating abnormalities detected by each device itself, the status detected by the processing of the communication device 1, and data indicating abnormalities for each power supply-related device P, U, D.

[0063] Server device 2 stores configuration data indicating the hierarchical structure of the energy storage module group L (domain, bank, module, cell) and / or power supply-related devices P, U, D in the monitored system. The monitored system or monitored device consists of one or more of the following: an energy storage system 101 including the energy storage module group L, a power conditioner P, an uninterruptible power supply U, and a rectifier D. If there is only one, it is called a monitored device; if there are multiple, it is called a system. The configuration data indicating the hierarchical structure may be set in advance for each system, or it may be derived from data transmitted from communication device 1, linked to each other in a parent-child relationship. If the power supply-related devices P, U, D of the monitored device are the monitored items, server device 2 stores configuration data indicating that the monitored items are being used individually. Server device 2 presents screen information visually showing the status at each hierarchical level in accordance with the hierarchical structure of the energy storage module group L (domain, bank, module, cell) and / or power supply-related devices P, U, D in the monitored system, in response to a request from client device 3.

[0064] Figure 4 is a flowchart illustrating an example of a processing procedure in server device 2. Server device 2 periodically acquires measurement data from communication device 1, the energy storage module group L, or power supply-related devices P, U, D, or in response to events, and stores it in storage unit 21. Using the stored information from the energy storage module group L or power supply-related devices P, U, D, server device 2 executes the processing shown in Figure 4 as an event or in response to a request from client device 3 to create information that forms the basis of screen information. An event may be the arrival of a periodic detection, or it may be the detection of a change in the state of the system or device, such as the occurrence of an abnormality.

[0065] The control unit 20 selects one identification data to identify the system or device to be monitored (step S101).

[0066] The control unit 20 determines whether the system or monitored device identified by the selected identification data includes an energy storage element (step S102). If it is determined that an energy storage element is included (S102: YES), the control unit 20 determines whether the system or monitored device identified by the selected identification data includes an energy storage element with a hierarchical structure (step S103).

[0067] If it is determined that the system or the device under monitoring includes a hierarchical energy storage element (S103: YES), the control unit 20 derives the state of charge (SOC) for each hierarchical level (step S104).

[0068] In step S104, if the energy storage element is a lithium-ion battery, the control unit 20 derives the SOC of each cell in each hierarchy using an algorithm for lithium-ion batteries. If the energy storage system 101 has a structure as shown in Figure 2, the hierarchy may be a domain, a bank, or a module, and the control unit 20 derives the SOC not only at the cell level but also at the domain, bank, and module levels. Alternatively, if the energy storage element is a lead-acid battery, the control unit 20 derives the SOC for the entire energy storage system 101 or for each divisible unit using an algorithm for lead-acid batteries.

[0069] The control unit 20 temporarily stores the SOC derived for each hierarchy, associating it with the currently selected identification data and the names (identification data) that identify each of the hierarchical energy storage element groups (energy storage module group L), i.e., domains, banks, etc. (step S105).

[0070] In step S103, if it is determined that the system or the device under monitoring does not contain a hierarchical energy storage element (S103: NO), the control unit 20 skips the processing in steps S104 and S105 and proceeds to step S106.

[0071] In step S106, the control unit 20 derives the State of Charge (SOC) for the entire energy storage element included in the system or monitored device of the selected identification data (step S106). The control unit 20 temporarily stores the SOC derived in step S106 in association with the selected identification data (step S107), and proceeds to step S108.

[0072] If it is determined in step S102 that the energy storage element is not included (S102: NO), the control unit 20 skips the processing in steps S104-S107 and proceeds to step S108.

[0073] The control unit 20 identifies whether or not there is an abnormality in the system or monitored device identified by the selected identification data (step S108), and temporarily stores the identified result in association with the identification data of the selected system or device (step S109).

[0074] The control unit 20 determines whether it has selected all the identification data that identifies the system or device being monitored (step S110). If it determines that all have been selected (S110: YES), the control unit 20 terminates the process. If it determines in step S110 that not all have been selected (S110: NO), the control unit 20 returns to step S101.

[0075] As shown in the flowchart in Figure 4, the status of each system and monitored device (SOC, and / or presence or absence of abnormalities) at the time of a request from client device 3 or the occurrence of an event (such as a change in state) is temporarily stored in the storage unit 21. The stored status information is updated each time a request is made from client device 3 or an event (such as a change in state) occurs.

[0076] This section describes the creation and presentation of screen information in server device 2. Figures 5 and 6 are flowcharts illustrating an example of the information presentation process from server device 2 to client device 3.

[0077] When client device 3 receives a login request from a maintenance worker via client program 3P, it sends login data to server device 2 (step S301). Upon receipt of the login data, the following processes begin.

[0078] The control unit 20, acting as a web server, receives login data along with a login request from the client device 3 (step S201). In step S201, the control unit 20 receives a key such as an ID and password to identify the maintenance worker using the client device 3. The control unit 20 may also receive biometric information instead of a password.

[0079] The control unit 20 extracts identification data of a system or monitored device that has access rights associated with an ID that identifies the maintenance worker, based on the received login data (step S202). If authentication of the received login data fails in step S202, the subsequent processing is omitted and the process is terminated.

[0080] The control unit 20 refers to the status data held by the process shown in Figure 4 for the system or monitored device identified by the extracted identification data (step S203).

[0081] The control unit 20 creates web page data (step S204) that includes a list of systems or monitored devices extracted in step S202, based on design data such as style sheets stored in the storage unit 21. The web page created in step S204 also includes link information to screens that display detailed information for each component of the power supply-related device, as well as the status of each hierarchical structure of the energy storage elements included in the system or monitored device (see Figure 8).

[0082] The control unit 20 sends the information of the created web page to the client device 3 that made the login request (step S205).

[0083] After the client device 3 transmits login data via the communication unit 32 (S301), it receives data from a web page containing a list of systems or monitored devices to which the maintenance worker performing the operation has access rights (step S302). The control unit 30 displays the web page on the display unit 33 (step S303).

[0084] As described above, the web page displayed in step S303 shows a list of systems or monitored devices. The list includes link information to display detailed information about each system or monitored device. The control unit 30 accepts the selection of link information on the web page (step S304) and sends a request for the data of the web page indicated by the selected link information to the server device 2 (step S305).

[0085] The control unit 20 of the server device 2 receives a request for data from a Web page with specified link information (step S206), and based on the link information, sends data from a Web page to the client device 3 to display details of the selected system or monitored device (step S207). The Web page data sent in step S207 has a configuration that allows transitions between hierarchies according to the hierarchical structure of the selected system or monitored device. Each Web page includes images showing the location of the selected system or monitored device within the building, within container C, within the battery panel, etc., and icons indicating the orientation of the images. The Web pages include graphic data such as illustrations, icons, and animations to represent the state of each hierarchical level. These graphics may be selectable by the operation unit 34. When selected, the control unit 30 transitions to a Web page of another level based on the link information associated with the graphic using the functions of the Web browser (see reference). The control unit 30 displays numerical values ​​of measurement data for the device or component on the screen using a script.

[0086] The control unit 30 of the client device 3 receives data from the web page (step S306) and, based on the received data, displays the detailed web page on the display unit 33 (step S307). Thereafter, as long as the display of the web page by step S307 is maintained, the control unit 30 receives data from the server device 2 regarding the state of the target hierarchy derived by the process shown in Figure 4, based on the measurement data of the selected system or monitored device, based on the script (automatic update) contained in the web page data, and updates and displays it on the web page. Figure 7 is a diagram illustrating the function of the automatic monitoring unit 2P. As shown in Figure 7, the automatic monitoring unit 2P's function, based on the actions of the web server program and design data contained in the server program 21P and the web browser program contained in the client program 3P, realizes the status display by automatic updates. The automatic monitoring unit 2P may, for example, transmit data to the client device 3 via HTTPS communication at intervals of 10 seconds or 15 seconds.

[0087] The control unit 30 determines whether link information to other levels has been selected on the Web page showing the details of the selected system or monitored device (step S308). If it is determined that link information has been selected, for example, by selecting a graphic to which link information is associated (S308: YES), it sends a request to the server device 2 for data on the Web page to display the details of the selected level based on the associated link information (step S309).

[0088] The control unit 20 of the server device 2 receives a data request specifying link information (step S208), and based on the link information, sends the data for the web page to display the details of the selected hierarchy to the client device 3 (step S209). The control unit 20 sends the web page data to the client device 3 each time it receives a data request specifying link information (S208) until the client device 3 terminates the display of the web page (S209).

[0089] The control unit 30 of the client device 3 receives data from a web page showing the details of the selected hierarchy (step S310). The control unit 30 displays the web page showing the details of the selected hierarchy on the display unit 33 (step S311). In step S311, as shown in Figure 7, while the web page display is maintained, the control unit 30 receives the status of the target hierarchy derived from the measurement data of the selected hierarchy from the server device 2, based on a script (automatic update) included in the data of the web page of the selected hierarchy, and updates and displays it on the web page.

[0090] The control unit 30 determines whether or not it has received an operation to terminate the display of the Web page of the target system or monitored device (step S312). If it determines that it has not received the operation (S312: NO), it returns to step S308. In step S312, the control unit 30 may determine that it has received the termination operation if the Web browser has been closed, logout has been selected, or transition to the Web page displayed in step S302 has been selected.

[0091] If it is determined that the termination operation has been accepted (S312: YES), the control unit 30 terminates the information presentation process.

[0092] In the processing procedures shown in Figures 5 and 6, it was explained that the web page for displaying information about the system or monitored device includes an automatic update script, and the status at each level is automatically updated (also referred to as the automatic monitoring function). Each time an automatic update occurs, the server device 2 updates the content of the web page periodically or in response to an event, according to the procedure shown in Figure 4, based on the derived status for each level and the results of the analysis process. Alternatively, the status update may be configured such that each time an operator operates the control unit 34 of the client device 3 to select another level or the top level, an update request is sent from the client device 3 to the server device 2. In this case, the server device 2 may, in response to the event that an update request has been received, perform the derivation of the status for each level and the analysis process for the target system according to the procedure shown in Figure 4, or it may periodically send the previously derived data.

[0093] Specific examples of web pages presented by server device 2 will be explained with reference to the figures. Figures 8-13 show specific examples of web pages. Figure 8 shows a web screen (a screen displayed on the display unit 33 of client device 3) 330 that shows a list of systems or monitored devices to which the logged-in maintenance worker has been granted authority. In the example of Figure 8, the names of the mega solar power generation system S shown in Figure 1, "XY City Mega Solar System", the wind power generation system W, "WZ Power Plant System", and other systems such as "K Railway System", "X Factory UPS", and "W Factory Energy Storage System" are displayed as lists.

[0094] The screen 330 in Figure 8 includes icons 331 that indicate the status of each system and monitored device. The icons 331 represent one of three statuses for the entire system or the monitored device: "abnormal," "caution," and "normal (no problem)." For example, the icon 331 for the "XY City Mega Solar System" is "normal." The icon 331 for the "WZ Power Plant System" is "abnormal." The icon 331 for the "K Railway System" is "caution."

[0095] Maintenance personnel can use the screen 330 displayed after logging in to recognize whether there are any abnormalities in each system or monitored device.

[0096] In the screen 330 of Figure 8, a "MAP" icon 332 is displayed corresponding to each system or monitored device. The "MAP" icon 332 is associated with a link to a screen that shows the details of the target system or monitored device. When a link is selected, the control unit 30 of the client device 3 requests the server device 2 to display the web page showing the details of the system or monitored device, specifying the link information.

[0097] Figure 9 shows an example of screen 333 when the "MAP" icon 332 of a system or monitored device is selected. Screen 333 in Figure 9 is displayed when "WZ Power Plant System" from the list of systems or monitored devices shown in Figure 8 is selected by the operation of the operation unit 34 of the client device 3. Screen 333 in Figure 9 shows the system configuration and status at the highest level of the hierarchical structure of the "WZ Power Plant System". Screen 333 in Figure 9 includes a layout image K (diagram) showing the arrangement of numerous energy storage module groups L. Specifically, layout image K represents the entire eight energy storage rooms that make up the "WZ Power Plant System" as seen from the top of the building. Each small rectangle in layout image K in Figure 9 represents a battery panel that houses three banks that make up a domain.

[0098] The screen 333 shown in Figure 9 includes an icon 334 near the layout image K, indicating that the layout image K represents a top-down view of the energy storage module group L. The icon 334 shown in Figure 9 represents a perspective view of the building (top floor) and has a downward-pointing arrow above the building. When creating the data for screen 333, the control unit 20 of the server device 2 selects the icon 334 indicating the orientation of the image from data that identifies the image used for the layout image K as representing a top-down view. Icon 334 also includes an icon indicating direction.

[0099] The screen 333 shown in Figure 9 includes a graphic object 335 that visually represents the status of the "WZ Power Plant System". The graphic object 335 is superimposed on the system layout image K. The graphic object 335 is a graphic that shows the status of the energy storage elements placed at that location. Depending on the overall system status (abnormal / caution / normal) on which the graphic object 335 is superimposed, the color and display format of the graphic object 335 may be different. In the screen 333 of Figure 9, the graphic object 335 indicating an "abnormal" state is superimposed on the area of ​​the second energy storage room from the right in the upper part (block A) of the screen 333.

[0100] Screen 333 in Figure 9 includes a graphic object 337 that shows the State of Charge (SOC) of the energy storage elements included in the system. The graphic object 337 may show the SOC of a single evaluation unit (the overall SOC of multiple modules or banks) with multiple modules, multiple banks, or multiple domains as the evaluation unit. In Screen 333 of Figure 9, the SOC value of the evaluation unit is displayed along the graphic object 337. The SOC value is calculated, for example, based on the SOC value calculated for each bank unit in which multiple modules are connected. The SOC value is a value calculated, for example, as an average value.

[0101] The screen 333 in Figure 9 includes an individual information field 339 for individually switching the display units for individual voltage, current, temperature, and other information of the lower layers in each hierarchy. The individual information field 339 includes buttons for selecting units such as voltage, current, temperature, resistance, and capacitance. When a unit is selected in the individual information field 339, the buttons in the individual information field 339 indicate whether "voltage," "current," or "temperature" is selected. While the graphic object 337 mentioned above displays bank-level information, when a unit is selected in the individual information field 339, the values ​​of the selected parameter among the voltage, current, and temperature of the battery panel, which is represented by a small rectangle on the layout image K in Figure 9, are displayed as text or the like. If the operator has selected "voltage" in the individual information field 339, and the operator selects a small rectangle on the screen 333 using the control unit 34, the total voltage or average voltage of the battery panel of the selected small rectangle will be displayed on or around the small rectangle.

[0102] As shown in Figure 9, screen 333 provides information that allows maintenance workers viewing screen 333 to grasp the overall situation of even large-scale ESS systems containing a vast number of modules, using the layout image K and graphic objects 335 and 337. Furthermore, the icon 334 allows maintenance workers viewing screen 333 to recognize that layout image K represents a top-down view of the system. Maintenance workers can easily identify which storage room within the building contains the energy storage element showing an abnormality on screen 333.

[0103] The screen information describing screen 333 includes a script that transitions to displaying the state of a lower hierarchy when a module, bank, or domain (i.e., the selection target in layout image K, which may be the same as the evaluation unit of SOC) is selected in layout image K.

[0104] Screen 333 may include a hierarchical menu 338 that displays the hierarchy of the energy storage system 101. In Figure 9, the hierarchical menu 338 shows the "overall" hierarchy corresponding to the top level. The hierarchy in the hierarchical menu 338 includes link information to return to the screen 333 of the higher level each time the hierarchy transitions from the top level to a lower level.

[0105] Figure 10 shows an example of screen 333 after transitioning to a status display of another layer. Screen 333 shown in Figure 10 is displayed on the display unit 33 when a range of energy storage rooms (for example, the part corresponding to the third energy storage room from the left in block A) on which a graphic object 335 indicating an "abnormal" state is superimposed on the layout image K shown in Figure 9 is selected. Screen 333 in Figure 10 includes a scaled-down version of the overall layout image K of the upper layer before the transition on the left side, and the layout image K of the selected energy storage room on the right side.

[0106] The layout image K of the selected energy storage chamber shown in the example in Figure 10 is an image that shows the arrangement of the energy storage module group L in unit units contained within the selected energy storage chamber. The layout image K in Figure 10 is a top view, similar to Figure 9. The small rectangle corresponding to the smallest unit contained in screen 333 in Figure 10 corresponds to a top view of a battery panel that houses three banks. A unit corresponds to multiple battery panels arranged in the width direction and back to back. Screen 333 in Figure 10 includes an icon 334 near the layout image K that indicates that the layout image K is viewed from a top perspective. The icon 334 shown in Figure 10 is the same as the icon 334 shown in Figure 9, so a detailed explanation is omitted.

[0107] In screen 333 of Figure 10, a graphic object 335 indicating an "abnormal" state is superimposed on the sixth unit from the left on the north side of the energy storage room shown in layout image K. Maintenance workers can easily recognize where in the energy storage room the energy storage element corresponding to the unit showing an abnormality in screen 333 is located.

[0108] Figure 11 shows an example of screen 333 after transitioning to a status display of another layer. Figure 11 is displayed on the display unit 33 when a range of units on which a graphic object 335 indicating an "abnormal" state is superimposed on the layout image K of the energy storage room shown in Figure 10 is selected. The screen 333 shown in Figure 11 includes a scaled-down version of the overall layout image K of the upper layer (energy storage room) before the transition on the left, and the layout image K of the selected unit on the right.

[0109] The layout image K of the selected unit shown in the example in Figure 11 is an image showing the arrangement of the energy storage module group L in units of the battery panel included in the selected unit. The layout image K in Figure 11 is a top view, similar to Figures 9 and 10. The small rectangle corresponding to the smallest unit contained in screen 333 in Figure 11 corresponds to a top view of the battery panel. Therefore, the layout image K in Figure 11 includes an icon 334 in its vicinity to indicate that the layout image K is viewed from a top perspective. The icon 334 shown in Figure 11 is the same as the icon 334 shown in Figure 9, so a detailed explanation is omitted.

[0110] In screen 333 of Figure 11, graphic objects 335 indicating an "abnormal" state are superimposed on the battery panel numbered "02" and the battery panel numbered "14" within the unit shown in layout image K. Maintenance workers can easily recognize which battery panel in the unit is located in screen 333 that indicates an abnormality.

[0111] Figure 12 shows an example of screen 333 after transitioning to a status display of another layer. Figure 12 is displayed on the display unit 33 when a range of the battery panel overlaid with a graphic object 335 indicating an "abnormal" state is selected on the unit layout image K shown in Figure 11. The screen 333 shown in Figure 12 includes a scaled-down version of the overall layout image K of the upper layer (unit) before the transition on the left, and the layout image K of the selected battery panel on the right.

[0112] The layout image K of the selected battery panel shown in the example in Figure 12 is an image showing the arrangement of the energy storage module group L within the bank when viewed from the front of the selected battery panel, which includes three banks. The small rectangles corresponding to the smallest unit contained in screen 333 in Figure 12 correspond to energy storage modules. In addition to the arrangement of energy storage modules, the layout image K of screen 333 in Figure 12 also shows rectangles representing the overall state of each of the three banks.

[0113] Near the layout image K in Figure 12, there is an icon 334 that indicates that the layout image K is viewed from a frontal perspective. The icon 334 in Figure 12 represents a perspective view of a rectangular prism, with an arrow pointing towards the back in the depth direction on the front of the rectangular prism. When the control unit 20 of the server device 2 creates the data for the hierarchical screen 333 in Figure 12, it selects the icon 334 indicating the frontal orientation from the data that identifies the image used for the layout image K as being viewed from a frontal perspective.

[0114] In screen 333 of Figure 12, graphic objects 335 indicating an "abnormal" state are superimposed on the energy storage modules labeled "01" and "11" in the third bank of the battery panel shown in layout image K. Maintenance workers can easily identify the location of the energy storage module indicating an abnormality within the battery panel.

[0115] Figure 13 shows an example of screen 333 after transitioning to a status display of another layer. Figure 13 is displayed on the display unit 33 when a module range is selected on the battery panel layout image K shown in Figure 12, overlaid with a graphic object 335 indicating an "abnormal" state. The screen 333 shown in Figure 13 includes a scaled-down version of the overall layout image K of the upper layer (battery panel) before the transition on the left, and the layout image K of the selected battery module on the right.

[0116] The layout image K of the selected energy storage module, shown as an example in Figure 13, is an image showing the arrangement of energy storage cells from the side view of a rectangular energy storage module that is long in the depth direction of a shelf-like battery storage panel. The small rectangles corresponding to the smallest unit contained in screen 333 in Figure 13 correspond to energy storage cells. Therefore, near the layout image K in Figure 13, there is an icon 334 that indicates that the layout image K is viewed from a side perspective. The icon 334 in Figure 13 represents a perspective view of a rectangular prism, and the side of the rectangular prism has an arrow pointing to the right or left in the width (left-right) direction. When the control unit 20 of the server device 2 creates the data for screen 333 of the hierarchy in Figure 13, it selects the icon 334 indicating the orientation of the side from data that identifies that it is a side view associated with the image used for layout image K.

[0117] In screen 333 of Figure 13, a graphic object 335 indicating an "abnormal" state is superimposed on the last energy storage cell labeled "16" within the energy storage module shown in layout image K. Maintenance workers can easily identify the location of the energy storage cell indicating an abnormality within the energy storage module.

[0118] As shown in Figure 9-13, the layout image K, graphic object 335, and icon 334 shown on screen 333 allow maintenance workers to easily understand the status of which part of the system or monitored device is being monitored. By checking screen 333, maintenance workers can determine in advance which device in the system and which part of the device they need to check. When maintenance workers go to the site, they can easily determine which part of which device they need to check by comparing the installation status of the energy storage elements or power supply-related devices P, U, D that they can see with screen 333.
