Information on the storage elements in which ranges are collectively displayed (for example, information on each factory area, each office, or each business entity) may be manually set by an operator or the like, or may be automatically set.

The status screen may include a photographic image taken at an overhead or bird's eye view of the storage element and/or the power supply related device of each system or each site. The captured image captured at the overhead or bird's-eye view may be a photographic image of a facility or a building in which the power storage element and/or the power supply-related device are installed, taken from a high place, or may be a photographic image of a satellite photograph. The status screen may include an illustration, a plan view, or a perspective view showing a building or a device in place of or in addition to the photo image.

According to the above configuration, it is possible to visually and intuitively grasp information including the state of the entire system or place and the position of the power storage element or the power supply related device, in which the system includes a large number of power storage elements used particularly in a large-scale system in a layered structure. The status screen transitions from the entire to a portion and from a portion to a more detailed portion according to the hierarchical structure. Each screen includes an image of the system of the electric storage element, and indicates where the electric storage element exists in the system. The operator can visually confirm through the graphics of the status screen that the system is being operated without problems, without having to check, for example, the SOC of each power storage element separately. In addition, the operator can intuitively grasp, through screen transition, what layered structure the power storage elements have in what positional relationship within the system. This can improve the operability of the system. When a problem occurs in the power storage element, the operator can visually grasp which layer the procedure is appropriate in, from the screen that is moved according to the layered structure.

The operator can quickly grasp which part of the power storage element has a problem in which position according to the overlapping position of the pattern with respect to the image and the pattern of the pattern, and the maintenance operation of the maintenance worker can be made efficient.

The position where the power storage element or the power supply-related device is captured or the position where the power storage element or the power supply-related device is drawn on the status screen may be stored in a relative position within the image for each image.

According to the above configuration, the display position of the graphic can be appropriately moved in accordance with the scaling of the image representing the building or the facility showing the power storage element or the power supply related device.

The remote monitoring system 100 can access information on the power storage elements and the power-related devices included in the super solar power generation system S, the thermal power generation system F, and the wind power generation system W from a remote location. A rectifier (a dc power supply device or an ac power supply device) D provided in an Uninterruptible Power Supply (UPS) U, a stable power supply system for a railway, or the like is also remotely monitored. The system can also be used for remotely monitoring a charging and discharging device (charging and discharging station) U and a system connection unit D instead of an uninterruptible power supply device and a rectifier. The charger and discharger U supplies electric power of a secondary battery mounted on an Electric Vehicle (EV) or a plug-in hybrid electric vehicle (PHEV) to a load or a system via a system connection unit in an emergency such as a disaster.

A Power Conditioner (PCS) P and a power storage system 101 are provided in parallel in the super solar power generation system S, the thermal power generation system F, and the wind power generation system W. The power storage system 101 is configured by arranging a plurality of containers C accommodating the power storage module group L in parallel. The electricity storage module group L includes a plurality of electricity storage elements. The power storage element is preferably a rechargeable power storage element such as a secondary battery or a capacitor, such as a lead storage battery or a lithium ion battery. A part of the electric storage element may be a non-rechargeable primary battery.

In the remote monitoring system 100, the communication device 1 (see fig. 2) is mounted on and connected to the power storage system 101 or the device (P, U, D and a management device M described later) in the system S, F, W to be monitored. The remote monitoring system 100 includes a communication apparatus 1, a server device 2 (information processing device) that collects information from the communication apparatus 1, a client device 3 (communication terminal device) that views the collected information, and a network N that is a communication medium between the devices.

The communication device 1 may be a terminal device (measurement monitor) that communicates with a Battery Management Unit (BMU) provided in the electric storage element and receives information on the electric storage element, or may be a controller that supports ECHONET/ECHONETLite (registered trademark). The communication device 1 may be a standalone device, or may be a network card type device that can be mounted on the power conditioner P and the power storage module group L. The communication device 1 is provided for each group (group) including a plurality of power storage modules in order to acquire information on the power storage module group L in the power storage system 101.

The access point AP is connected to the public communication network N1, and the client apparatus 3 can transmit and receive information to and from the server apparatus 2 via the network N from the access point AP.

The electricity storage module group L of the electricity storage system 101 has a layered structure. The communication device 1 that transmits information of the power storage elements to the server apparatus 2 acquires information of the power storage module group from the management apparatus M provided in the power storage module group L. Fig. 2 shows an example of the layered structure of the electricity storage module group L and the connection manner of the communication apparatus 1. The electricity storage module group L has a layered structure including, for example, a battery module (also referred to as a module) in which a plurality of electricity storage cells (also referred to as cells) are connected in series, a battery bank (bank) in which a plurality of electricity storage modules are connected in series, and a domain (domain) in which a plurality of battery banks are connected in parallel. In the example of fig. 2, 1 management device M is provided in each of the battery packs numbered (#)1 to N and the domain in which the battery packs are connected in parallel. The management device M provided for each battery pack communicates with a control board (CMU) with a communication function, which is built in each battery module, through serial communication, and acquires measurement data (current, voltage, and temperature) for the battery cells in the battery module. The management device M of the battery pack executes management processing such as detection of communication state abnormality. The management device M of the battery pack transmits measurement data obtained from the power storage modules of the respective battery packs to the management device M provided in the field. The management device M of the battery pack notifies the management device M of the domain of the detection of the abnormality. The management device M of the domain collects the measurement data obtained by the management device M of the battery pack belonging to the domain and the detected information such as the abnormality. In the example of fig. 2, the communication apparatus 1 is connected to a management device M of a domain.

The server device 2 creates screen information visually representing the state of the system or device to be monitored in accordance with the hierarchical structure of the battery cells, based on information acquired from the power storage elements or the power supply-related devices using the communication device 1, and transmits the screen information to the client device 3 to present the screen information.

Fig. 4 is a flowchart showing an example of a processing procedure of information presentation in the server apparatus 2. The server device 2 executes the following processing in response to a request from the client device 3 or as an event, using information of the power conditioner P, the power storage module group L (management device M), the uninterruptible power supply unit U, and the rectifier D periodically acquired from the communication apparatus 1 and stored in the storage unit 21. The event may be the arrival of a cycle, or the detection of a change in the state of a system or device such as the occurrence of an abnormality.

The control unit 20 selects 1 piece of identification information for identifying the system or device to be monitored (step S101).

The control unit 20 determines whether or not the system or device identified by the selected identification information includes a battery cell (step S102). If it is determined that the battery cell is included (yes in S102), it is determined whether or not the system or the device identified by the selected identification information includes a battery cell having a layered structure (step S103).

If it is determined in step S103 that the battery cells have a layered structure (yes in S103), control unit 20 derives the state of charge (SOC) for each layer (step S104). In step S104, the hierarchy is, for example, a domain, a battery pack, or a module as long as the power storage system 101 having the structure shown in fig. 2 is used.

The control unit 20 temporarily stores the SOC derived for each hierarchy layer together with the identification information of the power storage module group L of the upper hierarchy layer in association with the identification information of the system or device being selected and the name (identification number) of each power storage module group L identifying the hierarchy structure (step S105).

If it is determined in step S103 that the hierarchical structure is not included (no in S103), the control unit 20 derives the SOC of the entire battery cell included in the system or device identified by the selected identification information (here, only the SOC transmitted from the management device M is presented) (step S106), and temporarily stores the SOC in association with the identification information of the system or device being selected (step S107).

Next, the control unit 20 identifies whether or not there is an abnormality in the system or device identified by the selected identification information (step S108), and temporarily stores the identified result in association with the identification information of the system or device being selected (step S109).

If it is determined in step S102 that the battery cell is not included (no in S102), the control unit 20 advances the process to step S108.

The control unit 20 determines whether or not all identification information for identifying the system or the device to be monitored is selected (step S110). If it is determined that all the processes have been performed (S110: yes), the control unit 20 ends the primary process. If it is determined in step S110 that all the systems or apparatuses have not been selected (no in S110), the control unit 20 returns the process to step S101 to select the identification information of the next system or apparatus.

Through the processing shown in the flowchart of fig. 4, the state at the timing of the request from the client apparatus 3 or the timing of the occurrence of an event (such as a state change) is temporarily stored in the temporary storage unit built in the storage unit 21 or the control unit 20. The stored information of the state is updated whenever there is a request from the client apparatus 3 or whenever an event occurs.

Fig. 5 and 6 are flowcharts showing an example of a processing procedure for presenting information from the server apparatus 2 to the client apparatus 3. When the client apparatus 3 receives a login request from the Web browser, the following processing is started.

The control unit 20 serves as a Web server and transmits data of a login page for accepting login data in the client apparatus 3 to the client apparatus 3 (step S201). On the login screen displayed on the display unit 33 of the client apparatus 3, the control unit 20 receives login data based on an operation in the operation unit 34 (step S202). The login data includes an ID and a password that identify a manager or operator who uses the client device 3. The login data may include biometric information instead of the password.

The control unit 20 extracts, based on the received login data, identification information of the system or device having the access authority stored in association with the login data (step S203). The control unit 20 refers to the storage of the presence or absence of abnormality of each of the systems or devices corresponding to the extracted identification information (step S204). In step S204, the control unit 20 refers to the information on the presence or absence of an abnormality which is appropriately updated according to the flowchart of fig. 4. The control unit 20 transmits information on a Web page to which an icon indicating the presence or absence of an abnormality referred to in step S204 is added to a list of link information to another Web page for displaying information on each of the systems and apparatuses corresponding to the identification information extracted in step S203, to the client apparatus 3 (step S205). In the case where the system or device having the access authority corresponding to the login information is single, in step S205, data of a Web page for displaying information of the single system or device is transmitted to the client device 3 (S207 described later).

The client apparatus 3 receives data of a Web page in a list of systems or apparatuses having an access right through the communication unit 32 (step S301), and displays the Web page in the list on the display unit 33 (step S302). The control unit 30 receives a selection of a desired system or device from the list of link information displayed based on the received data (step S303), and transmits a request for data of a Web page indicated by the selected link information to the server device 2 (step S304).

The control section 20 of the server apparatus 2 receives a data request of a Web page of a target system or apparatus (step S206), and transmits data of the Web page for displaying information of the selected system or apparatus to the client apparatus 3 (step S207). The data of the Web page transmitted in step S207 includes image data such as an image indicating the selected system or device, an image indicating the arrangement, coordinate data indicating the position of the system or device within the image, and an illustration, an icon, a pop-up window, or animation for representing the state.

The control unit 30 of the client apparatus 3 receives the data of the Web page (step S305), and requests the server apparatus 2 to acquire the state of the selected system or apparatus based on the script included in the received data (step S306).

The control unit 20 of the server apparatus 2 receives the status acquisition request (step S208), and determines the status and presence/absence of an abnormality of the uppermost layer of the target system or apparatus, that is, the entire system or apparatus (step S209). When the control unit 20 stores the state for each hierarchy, the control unit 20 refers to the state of the uppermost hierarchy. The control unit 20 transmits data indicating the state and the presence or absence of an abnormality determined in step S209 for the selected system or device to the client device 3 (step S210).

The control unit 30 of the client apparatus 3 receives data indicating the state and presence or absence of an abnormality of the target system or apparatus (step S307). The control unit 30 selects graphic data corresponding to the status or presence or absence of an abnormality indicated by the received data from the received data (step S308), and causes the display unit 33 to display a Web page including an image indicating the target system or device using the selected graphic data or the like (step S309).

The control unit 30 of the client apparatus 3 determines whether or not another tier is selected for the power storage module group L having a tier structure included in the target system or apparatus (step S310). If it is determined in step S310 that the module group L is selected (yes in step S310), the server device 2 is requested to acquire the state of the selected hierarchical power storage module group L (step S311).

The control unit 20 of the server device 2 receives the state acquisition request (step S211), and specifies the state and presence or absence of an abnormality of the power storage module group L of the target tier (step S212). The control unit 20 transmits data indicating the state and the presence or absence of an abnormality determined for the selected power storage module group L of the tier to the client device 3 (step S213).

The control unit 30 of the client apparatus 3 receives data indicating the state and presence or absence of an abnormality of the selected hierarchy (step S312). The control unit 30 selects graphic data corresponding to the status indicated by the received data or the presence or absence of an abnormality from the received data (step S313), and causes the display unit 3 to display a Web page including an image indicating the status of the target layer using the selected graphic data or the like (step S314).

The control unit 30 of the client apparatus 3 determines whether or not the completion operation of the display of the Web page of the target system or apparatus is accepted (step S315), and if it is determined not to be accepted (S315: no), returns the process to step S310. Whether or not the completion operation of step S315 is accepted is determined based on whether or not the Web browser is completed, whether or not log out is selected, or whether or not migration to a Web page in a list of systems or devices having access authority is selected.

If it is determined in step S315 that the completion operation has been accepted (yes in S315), the information presentation process is completed.

The processing procedure shown in the flowcharts of fig. 5 and 6 will be described with reference to a specific screen example. Fig. 7 to 16 show examples of screens displayed based on the screen information. Fig. 7 shows a Web screen 330 (a screen displayed on the display unit 33 of the client apparatus 3) including a list of names of authorized systems or apparatuses in step S302. In the example of fig. 7, the names "XY city super solar system" of the super solar power generation system S, the names "WZ power plant system", "K railway system", and "X plant system" of the thermal power generation system F shown in fig. 1 are displayed as links together with the identification information. The name "XY city super solar system" may indicate a place where the power storage module group L and/or the device P, U, D are installed. The list of Web screen 330 includes icons indicating the presence or absence of an abnormality specified for each system.

Next, an example of a screen when a system or a device is selected will be described. Fig. 8 shows a status screen 331 indicating the status of the selected system or device as a whole. The status screen 331 in fig. 8 is displayed when the "XY city super solar system" in the list shown in fig. 7 is selected by the operation of the operation unit 34 of the client apparatus 3, and includes an image K (illustrated in a line drawing in fig. 8) which is an aerial photograph obtained by imaging a plurality of containers C housing a plurality of solar panels and a plurality of power storage module groups L. The image K may be an illustration instead of a photograph image. The status screen 331 includes an image K of the system and a graphic object 332 visually indicating the status of the "XY city super solar system". In the example shown in fig. 8, the graphic object 332 is a circular icon that selects a different color according to the state that has been determined. In fig. 8, an icon indicating that there is an abnormal color is selected and displayed. The display position of the graphic object 332 is included in the design data of the status screen 331 in association with the image K by the relative position with respect to the image K, and is stored in the storage unit 21. Thus, the graphic object 332 is appropriately moved according to the scaling of the image K. The status screen 331 including the graphic object 332 allows visual confirmation of the arrangement of the plurality of solar panels and the container C, and allows confirmation from the client apparatus 3 that the "XY city super solar system" is being used as a whole without any problem.

A switching interface 333 is included in the status screen 331. In the example shown in fig. 8, the switching interface 333 includes buttons or icons that can select 3 of "photograph", "plan view", and "3D", respectively. The switching interface 333 may be an interface in which 1 button of "photograph", "plan view", or "3D" is cyclically switched every selection.

The screen information of the status screen 331 shown in fig. 8 includes a scenario for transitioning to a display in a lower hierarchical state when the graphics object 332 is selected. When the graphic object 332 is selected by the operation unit 34, it is determined that another hierarchy or a lower hierarchy is selected in step S310 in the processing procedure shown in the flowcharts of fig. 5 and 6 (S310: yes).

Fig. 9 shows an example of a status screen 331 in which the status display has transitioned to another hierarchical level. Fig. 9 is a status screen 331 showing the status of the level (level) of the container C included in the "XY city super solar system" shown in fig. 8. On the status screen 331 of fig. 9, the status of each of the containers C, that is, the status of the power storage module group L included in the container C is displayed. On the status screen 331 of fig. 9, a graphic object 332, which is a circular icon drawn in a color in the case where there is an abnormality, is displayed on the perspective view of the container C including the power storage module group L determined to have an abnormality. Selectable graphical objects 332 may be displayed on each container regardless of the presence or absence of an anomaly. The hierarchical state screen 331 corresponding to each container C shown in fig. 9 also includes a scenario for transitioning to the display of the lower hierarchical state when the graphics object 332 is selected.

Fig. 10 shows an example of a status screen 331 in which the status display has transitioned to another hierarchical level. Fig. 10 shows a domain-level status screen 331 included in the container C included in the "XY city super solar system" shown in fig. 9. The status of each of the 2 fields included in the container C is displayed on the status screen 331 of fig. 10. In fig. 10, domain identification information (domain #) for identifying each domain in the system is shown. On the state screen 331 of fig. 10, a graphic object 332, which is a circular icon drawn in a color in the case where there is an abnormality, is displayed on the perspective view of the power storage module group L identified as the region where there is an abnormality. Selectable graphical objects 332 may also be displayed on each container regardless of the presence or absence of an anomaly. The status screen 331 of each domain shown in fig. 10 also includes a scenario for transitioning to a display of a lower hierarchical state when the graphic object 332 is selected.

Fig. 11 shows an example of the status screen 331 for each hierarchy. Fig. 11 shows a page showing detailed information of a domain selected from the status screen 331 of each domain shown in fig. 10. Fig. 11 shows a state screen 331 including the state (normal/abnormal) of the selected domain, the total voltage, current, cell voltage, SOC, and distribution (the highest value, the average value, and the lowest value) of the domain. In the domain status screen 331, as shown in fig. 11, a link to the detailed information of each of the battery packs included in the domain may be included.

The status screen 331 displayed in accordance with the selection of the hierarchy shown in fig. 10 and 11 includes a path (foot path)334 indicating the hierarchy being selected. By the path 334, selection of another hierarchical layer including an upper layer can be performed. In this way, the state of each layer of the power storage module group L is easily and intuitively grasped by being displayed on the state screen 331 visually shown in a perspective view. The hierarchical state in the upper and lower relation can also be intuitively grasped by the selection of the graphic object 332 and the selection of the path 334 in the state screen 331.

The transition from the state screen 331 shown in fig. 8 to the state screen 331 shown in fig. 9 and the state screen 331 shown in fig. 10 can be displayed as an animation.

Fig. 12 shows another example of the status screen 331. The status screen 331 in fig. 12 is displayed when "X plant system" in the list shown in fig. 7 is selected by the operation of the operation unit 34 of the client apparatus 3. The status screen 331 includes an image K (depicted by a line drawing in fig. 12) that is an aerial photograph of a factory including a building in which the power storage module group L is provided indoors. The status screen 331 includes a system image K and a graphic object 332 visually indicating the status of the "X plant system" as in the above-described fig. 8. In the example shown in fig. 8, the graphic object 332 is a circular icon drawn with a color indicating an abnormality. The display position of the graphic object 332 is included in the design data of the status screen 331 by corresponding to the image K with a relative position with respect to the image, and is stored in the storage unit 21. Thus, the graphic object 332 is appropriately moved according to the scaling of the image K. By the status screen 331 including the graphic object 332, it is possible to visually confirm the location of the building in which the power storage module group L is installed, and to confirm that the "X plant system" is being used as a whole on the display unit 33 of the client apparatus 3 without any problem.

The screen information of the status screen 331 shown in fig. 12 includes a scenario for transitioning to a display in a lower hierarchical state when the graphics object 332 is selected. When the graphic object 332 is selected by the operation unit 34, it is determined in step S310 in the processing procedure shown in the flowcharts of fig. 5 and 6 that another hierarchy or a lower hierarchy is selected (yes in S310).

Fig. 13 shows an example of a status screen 331 which transitions to another hierarchical status display. The status screen 331 shown in fig. 13 includes an image K that is a drawing of the floor of the building in which the power storage module group L of the "X plant system" shown in fig. 12 is installed. On the image K, the status screen 331 includes a graphic object 332 indicating the position of the room in which the power storage module group L is installed and the status of the power storage module group L. The graphic object 332 shown in fig. 13 is a circular icon drawn in a color when there is an abnormality. The graphical object 332 may also be displayed regardless of the presence or absence of an anomaly. The status screen 331 shown in fig. 13 also includes a scenario for transitioning to the display of the lower hierarchical level when the graphic object 332 is selected.

Fig. 14 shows an example of a status screen 331 which transitions to another hierarchical status display. The status screen 331 shown in fig. 14 includes, as an image K, a perspective view showing a rack (rack) to which a plurality of power storage module groups L are attached, which is displayed when a room in which the graphics object 332 shown in fig. 13 is displayed in an overlaid manner is selected. The image K may be a photographic image. The status screen 331 in fig. 14 also includes a graphic object 332 in the image K indicating the position of the rack in which the power storage module group L is stored and the status of the stored power storage module group L. The graphic object 332 shown in fig. 14 is a circular icon drawn in a color when there is an abnormality. The graphical object 332 may also be displayed regardless of the presence or absence of an anomaly. The status screen 331 shown in fig. 14 also includes a scenario for transitioning to the display of the lower hierarchical level when the graphic object 332 is selected.

Fig. 15 shows an example of a status screen 331 which transitions to another hierarchical status display. When the graphic object 332 shown in fig. 14 is selected, a status screen 331 shown in fig. 15 is displayed. The status screen 331 includes a configuration diagram representing the battery pack unit blocks of the power storage module group L stored in the rack as an image K. The status screen 331 of fig. 15 also includes a graphic object 332 indicating the status of the power storage module group L on the image K. In the example of fig. 15, a graphic object 332, which is a circular icon drawn in a color at the time of abnormality, is displayed on a block corresponding to a battery pack determined to have an abnormality. The graphic object 332 may be displayed on a block corresponding to each battery pack regardless of the presence or absence of an abnormality. The status screen 331 shown in fig. 15 also includes a scenario for transitioning to the display of the lower hierarchical level when the graphics object 332 is selected.

Fig. 16 shows an example of the status screen 331 for each hierarchy. Fig. 16 shows a page showing detailed information of the battery pack selected from the status screen 331 including the configuration diagram in units of battery packs shown in fig. 15. In fig. 16, a state screen 331 including the state (normal/abnormal) of the selected battery pack, the total voltage of the battery pack, the current, the cell voltage, the SOC, and the distribution (highest value, average value, and lowest value) of the temperature is shown. As shown in fig. 16, the battery pack status screen 331 may include a link to detailed information of modules included in the battery pack.

In this way, on the Web page displayed when the maintenance person or administrator using the client apparatus 3 selects one of the systems or apparatuses having authority, the status screen 331 including the graphic object 332 indicating the entire status and the presence or absence of an abnormality is displayed in layers. This allows the maintenance person or manager to visually and intuitively grasp the state of the entire system. The status screen 331 is displayed in a hierarchical order by the processing procedure shown in the flowcharts of fig. 5 and 6, and the maintenance person or manager can grasp the status one by one.

Fig. 17 is a diagram showing another example of the status screen 331. In fig. 17, a graphic object 332 is an icon representing the SOC in the selected system or device. The graphic object 332 in fig. 17 contains an illustration of the battery, and the SOC is represented by the number of blocks within the illustration. The illustration of the battery of graphical object 332 is depicted with a color indicating an anomaly.

The status screen 331 in fig. 17 includes an enlargement control 335 for the image K. Fig. 18 shows an enlarged view of the status screen 331 of fig. 17. Fig. 18 includes a graph object 332 in the form of a bar graph representing the SOC of the power storage module group L included in the system or device selected when enlarged by the enlargement control 335 included in the status screen 331 of fig. 17, in units of containers C. The present invention is not limited to the bar chart, and a pie chart or a two-dimensional chart showing the SOC distribution in time series may be displayed. In the example shown in fig. 18, a dialog box including a text indicating the content of an abnormality and a numerical value indicating the SOC is displayed for the container C of the power storage module group L including the state of an abnormality, and an icon corresponding to the content of an abnormality is displayed. In the state screen 331, when a pointing (pointing) such as a cursor is superimposed on each of the containers C, the SOC of the storage module group L included in each of the containers C may be output as a numerical value or by drawing.

Fig. 19 shows another example of the status screen 331. In fig. 19, the graphic object 332 is a graphic depicted with a shape and a color covering the range of the selected system or apparatus. Graphical object 332 in fig. 19 is depicted with a color indicating an anomaly. The drawing may be performed in a gradation manner according to the state of each container C. In this case, the portion of the container C including the power storage module group L indicating an abnormality overlapping the imaging range may be drawn in a warm color such as red or orange, and the portion of the container C including the normal power storage module group L overlapping the imaging range may be drawn in a cold color such as blue or green.

Fig. 20 shows another example of the status screen 331. Fig. 20 shows an example of an image K displayed when the icon "plan view" is selected in the switching interface 333 in fig. 8. When the image K is changed from the photo image to the plan view through the switching interface 333 of the status screen 331, the graphic object 332 is also displayed based on the relative position stored in correspondence with the image K stored as the "plan view" of the "XY city super solar system".

Fig. 21 is a diagram showing another example of the status screen 331. Fig. 13 shows an example of an image K displayed when the icon "3D" is selected in the switching interface 333 in fig. 8. Even when the image K is changed from the photographic image to 3D, that is, to a three-dimensional image through the switching interface 333 of the status screen 331, the graphic object 332 is displayed based on the relative position stored in association with the image K stored as the "three-dimensional image" of the "XY city super solar system".

In this manner, on the Web page displayed when the serviceman or the administrator using the client apparatus 3 selects one of the systems or apparatuses having the authority from the list, the status screen 331 is displayed, and the status screen 331 includes the graphic object 332 indicating the status of the whole and the presence or absence of an abnormality. This allows the maintenance person or manager to visually and intuitively grasp the state of the entire system. The status screen 331 is updated every time the screen is refreshed, for example, by the processing procedure shown in the flowcharts of fig. 5 and 6, and the maintenance person or manager can grasp the status one by one.

The above embodiments are illustrative in all respects and not restrictive. The scope of the present invention is indicated by the appended claims, and all changes that come within the meaning and range of equivalency of the claims are intended to be embraced therein.

In the above embodiment, the state of the power storage element is shown graphically on the state screen, but the state of the power supply-related device may be shown graphically. For example, the state of the charger and discharger U of fig. 1 may also be represented graphically, and the state of the coupling control unit D may be represented graphically. These figures may also be displayed superimposed on the image of the facility or site where the charger and discharger U and the system connection unit are provided. When the system connection unit includes the power storage element and the power conditioner (power converter), the state of the system connection, the state of the power storage element, the state of the power conditioner, and the like may be graphically represented.

In a system in which the power storage element and the power supply-related device operate in association with each other, the states of the power storage element and the power supply-related device can be grasped more effectively by displaying them together. Further, by displaying the states of different monitoring objects related to the power together on a common image, maintenance (including planned maintenance and preventive maintenance) of the entire system is facilitated. Conventionally, in maintenance of a system including a power storage element and a power supply-related device, a maintenance support system has been used in which the power storage element itself or the power supply-related device included in the system is independently developed. The use methods and display modes of the maintenance auxiliary systems are not unified, and the maintenance management is complicated. The technique disclosed in the present specification significantly improves usability and maintainability.
