Specifically, network information such as an IP address (IPv4 and IPv6) of the communication device 1 itself, a gateway, a DNS address, a global address, and a global address of the server device 2 is received. The control unit 10 stores these pieces of information in the storage unit 11 or the built-in memory, and the second communication unit 13 connects to the network N based on this information.

  The control unit 10 of the communication device 1 accepts the setting of which level of the management device M in the hierarchical structure of the storage elements is connected (lower layer presence / absence) (step S102). In step S <b> 102, the control unit 10 receives a selection as to whether the control unit 10 is connected to the domain management apparatus M or the bank management apparatus M. When connected to the bank management apparatus M, in a case where a higher domain exists, it is preferable to accept the setting of which domain the bank belongs to.

Accepts the setting of whether or not is connected. Alternatively, a setting as to whether another communication device 1 is connected to the upper layer management apparatus M may be accepted. Specifically, when the management apparatus M to which the control unit 10 is connected corresponds to a domain, the control unit 10 receives a setting as to whether or not the communication device 1 is connected to the management apparatus M in the lower bank.

  The control unit 10 receives the setting of identification information for identifying the power storage element covered by the connected management device M and the system including the power storage element (step S104). The identification information includes a location ID (identification number, symbol or name) for identifying a place where the system is installed, and a minor ID (identification number, symbol, name) for identifying the unit of the power storage module group L in the same location. Or a name). The location ID and minor ID may be issued by the server device 2.

  Based on the settings received in steps S101 to S104, the control unit 10 stores the setting information including the network information, the hierarchical structure, the connection relationship, and the identification information in the storage unit 11 or the built-in memory (step S105), and ends the processing. .

  In the processing procedure shown in the flowchart of FIG. 6, each communication device 1 is configured to accept communication settings and connection relationship settings. However, the communication device 1 may automatically detect and set connection relationships. When communicating with each other by the CAN connection in the power storage system 101, it is preferable to set one of them as a master and to create and transmit hierarchical data that matches the connection configuration between the communication devices 1.

FIG. 7A shows setting information stored in the communication device 1 in the connection form of FIG. In the example shown in FIG. 7A, the communication device 1 is connected only to the management apparatus M in a domain including a plurality of banks. Therefore, “domain” and domain identification number are set as the connection management device (hierarchy of the connected management device M), and the relationship with other communication devices 1 is “no lower layer” (lower layer or bank). No other communication device 1 exists in the management apparatus M). In the example shown in FIG. 7A, a location ID and a minor ID are set as identification information.

  FIG. 7B shows setting information stored in the communication device 1 in the connection form of FIG. In the example shown in FIG. 7B, the communication device 1 is connected only to the management apparatus M in one bank. Therefore, “bank” is set as the connection management device. In consideration of the existence of other banks at the same installation location, both bank identification numbers may be set. As the relationship with the other communication device 1, “no lower layer” (the lower layer, that is, the module, the management apparatus M and the other communication device 1 do not exist) is set. In the example shown in FIG. 7B, a location ID and a minor ID are set as identification information.

  FIG. 8 is a diagram illustrating another example of the setting information stored in the communication device 1. FIG. 8A shows the setting information stored in the communication device 1a connected to the domain management apparatus M in the connection form of FIG. In the connection form of FIG. 5 corresponding to FIGS. 8A and 8B, a plurality of communication devices 1a-1n are connected in a hierarchical structure.

In the communication device 1a, “with lower layer” (the other communication device 1b-1n exists in the lower layer, ie, the bank management apparatus M) is set as the relationship with the other communication device 1.

  FIG. 8B shows setting information stored in the communication device 1c connected to the management apparatus M in the bank (# 2). The setting information in the communication devices 1b,..., 1n in other banks is the same as that in FIG. In the communication device 1c connected to the management apparatus M of the bank (# 2) in FIG. 5, as shown in FIG. 8B, “bank” is set as the connection management apparatus, and the identification number (“bank”) ( # 2) is set. The identification number (# 1) of the domain to which the bank belongs is also set. In the communication device 1c, “no lower layer” (the management device M and the other communication device 1 are not present in the lower layer, that is, the power storage module) is set as the relationship with the other communication device 1.

  A processing procedure in each communication device based on the setting information illustrated in FIGS. 7 and 8 will be described. FIG. 9 is a flowchart illustrating an example of a transmission procedure of information of each communication device 1. The control unit 10 of the communication device 1 continuously repeats the following processing procedure while it is activated.

  The control unit 10 determines whether or not it is a predetermined timing for acquiring the state (step S201). Predetermined timing refers to whether the cycle time has elapsed, the number of information (predetermined units) stored in the storage unit 11, the amount of information has reached a predetermined set time or quantity, or a notification from the management device M Etc. If it is determined that it is not the predetermined timing (S201: NO), it waits until it is determined that it is the predetermined timing.

  When it is determined that the predetermined timing is reached (S201: YES), the control unit 10 acquires, from the management device M, information on the state of the storage element in the storage module group L acquired by the connected management device M. (Step S202). The control part 10 memorize | stores the acquired information in the memory | storage part 11 with time information (step S203).

  The control unit 10 refers to the setting information (step S204), and determines whether another communication device 1 exists in the lower layer (there is a lower layer) (step S205). When it is determined that another communication device 1 exists in the lower layer (S205: YES), the control unit 10 uses the information acquired in step S202 to describe data describing the state of the connection management device in the hierarchy indicated by the setting information. Create (corresponding to “creating unit” in step S206). Step S206 may be executed by the management apparatus M. The data created in step S206 includes status information and time information for each layer on which an operation such as calculating the average of current, voltage, and temperature is performed by the management apparatus M. The data format is a text data file, a CSV file handled by a spreadsheet application program, or the like. It may be a graph showing information in time series or a data file obtained by imaging the graph. The control unit 10 temporarily stores the created data as a folder corresponding to the hierarchy of the connection management device indicated by the setting information in the storage unit 11 or the built-in RAM (step S207). The process of storing as a folder includes assigning the same directory name (or path name) corresponding to the hierarchy to which the plurality of data files describing the acquired state information and the created state information are connected. The process in step S205 may determine whether another communication device 1 exists in the upper layer.

  The control unit 10 determines whether it is the transmission timing of the created data (step S208). In step S208, the transmission timing is determined by determining whether the cycle time has elapsed, the number of pieces of information stored in the storage unit 11, the amount of information has reached a predetermined set time or quantity, or an inquiry from the server device 2 as in step S201. It was whether there was.

  If it is determined in step S208 that the transmission timing is reached (S208: YES), the control unit 10 compresses the folder stored in the storage unit 11 or the built-in RAM (step S209). The control unit 10 associates the connection management device and identification information of the own device (communication device 1) included in the setting information referred to in step S204, and sets the folder after compression processing of the server device 2 included in the setting information. It transmits to the server apparatus 2 based on the global address (step S210, corresponding to “transmission unit”). The control part 10 complete | finishes a process and the process after step S201 is started again.

  When it is determined in step S208 that the transmission timing is not reached (S208: NO), the control unit 10 ends the process as it is, and the process from step S201 is started again.

  When it is determined in step S205 that no other communication device 1 exists (no lower layer) (S205: NO), the control unit 10 stores data describing the state of the connection management device in the hierarchy indicated by the setting information. It creates based on the information acquired at step S202 (step S211). The control unit 10 acquires the state in the lower layer from the lower layer management apparatus M (step S212), and creates data describing the state in the lower layer (step S213). Steps S211 and S213 may be executed by the management apparatus M. The data created in steps S211 and S213 includes state information and time information for each layer on which an operation such as calculating an average of current, voltage, and temperature in each layer is performed. The data format is a text data file, a CSV file related to a spreadsheet, or the like. It may be a graph showing information in time series or a data file obtained by imaging the graph.

  The control unit 10 includes the status information acquired from each management device M and the data created in step S213 in the subfolder corresponding to the lower layer, and the storage unit 11 as a hierarchical folder including the data created in step S211. Or it memorize | stores in built-in RAM (step S214). The control unit 10 advances the process to step S208.

  10 and 11 are diagrams illustrating examples of the contents of data transmitted to the server device 2. The hierarchical structure of the data shown in FIGS. 10 and 11 corresponds to the hierarchical structure of the storage elements shown in FIGS. 3 to 5 and the connection form of the communication device 1, and is created by the processing procedure shown in the flowchart of FIG. The folder to be compressed and the folder to be compressed are schematically shown.

  FIG. 10A corresponds to the hierarchical structure of the power storage elements including the domain and the bank illustrated in FIG. 3 and the connection form of the communication device 1 connected only to the domain management apparatus M. In a hierarchical structure in which a plurality of banks are included in one domain, the communication device 1 is connected only to the domain management apparatus M. In this case, the communication device 1 creates a folder FA in which data files including information obtained from the management devices M of each layer are stored in subfolders having a hierarchical data structure as shown in FIG. 10A. When transmitting data to the server device 2, the communication device 1 creates and transmits a folder ZFA obtained by compressing the folder FA.

  FIG. 10B corresponds to the hierarchical structure of the storage elements of a single bank shown in FIG. 4 and the connection form of the communication device 1 connected only to the management device M of the bank. In the hierarchical structure of only one bank, the communication device 1 is connected only to the management apparatus M of that bank. In this case, the communication device 1 acquires data obtained from the control board of each power storage module from the management apparatus M, and creates a folder FB accommodated in a subfolder having a hierarchical data structure as shown in FIG. 10B. When transmitting data to the server device 2, the communication device 1 creates and transmits a folder ZFB obtained by compressing the folder FB.

  FIG. 11 corresponds to the hierarchical structure of the power storage elements including the domains and banks shown in FIG. 5 and the connection form of the plurality of communication devices 1 connected to the management devices M of the domains and banks. A communication device 1 is connected to each of the domain management apparatus M and the bank management apparatus M. Among the communication devices 1, the communication device 1 a connected to the domain determines that the lower layer is present in the control unit 10. Therefore, the lower layer state is not acquired, and the level of the connection management device indicated by the setting information (FIG. 8A) A folder FCa containing data describing the state is created. The folder FCa does not include a subfolder including lower-layer state data. For the communication devices 1b, 1c,..., 1n connected to the bank, the control unit 10 determines that there is no lower layer, data describing the state of the connection management device hierarchy indicated by the setting information (FIG. 8B), and a plurality of data Folders FCb, FCc,..., FCn that hierarchically include folders including data of the respective storage modules are created. Each of the communication devices 1a, 1b, 1c, ..., 1n creates folders ZFCa, ZFCb, ZFCc, ..., ZFCn obtained by compressing the created folders and transmits them to the server apparatus 2.

  FIG. 12 is a flowchart illustrating an example of a data acquisition procedure in the server device 2. In the server device 2, the control unit 20 receives data (folder) transmitted from the communication device 1 (step S301). The control unit 20 determines whether or not other data (folders) corresponding to the upper and lower levels of the hierarchical structure is stored in the storage unit 21 based on the connection management device and the identification information associated with the received data. (Step S302). In step S302, for example, when the control unit 20 receives data (folder) from the communication device 1 having a domain and a bank having the same location ID and minor ID respectively as connection management devices, the control unit 20 moves up and down. Judge that it is equivalent.

  When it is determined in step S302 that other data has already been stored in the storage unit 21 (S302: YES), the control unit 20 includes the corresponding other data (folder) and the data received in step S301. Is updated to the data in the storage unit 21 (step S303), and the process ends.

  When it is determined in step S302 that no other data is stored (S302: NO), the control unit 20 stores the received data in the storage unit 21 (step S304), and ends the process.

  FIG. 13 is a diagram illustrating a specific example of data acquisition in the server device 2. The example shown in FIG. 13 corresponds to the hierarchical structure of the power storage elements shown in FIG. 5 and the connection form of the plurality of communication devices 1, and the server apparatus 2 includes the communication devices 1a, 1b, Folders ZFCa, ZFCb, ZFCc,..., ZFCn transmitted after compression processing from 1c,. When receiving the folder ZFCa received from the communication device 1a, the control unit 20 of the server device 2 identifies the corresponding location ID “12345”, minor ID “(000001) 1 system”, and the connection management device is a domain. The identification information whose number is “1” and the information of the connection management device are received. When receiving the folders ZFCb, ZFCc,... Received from the communication devices 1b, 1c,..., Etc., the control unit 20 corresponds to the corresponding location ID “12345” (identification number) and minor ID “(000001) 1 system” ( Identification number and name), that the connection management device is a bank, identification information that is the identification number, and connection management device information are received.

  The control unit 20 of the server device 2 can recognize that the location ID and the minor ID are the same, and that one connection management device is a domain and the other connection management device is a bank, which corresponds to the upper and lower levels of the hierarchy. It is determined that data is stored (S302: YES). The control unit 20 stratifies the folders FCb, FCc,... Obtained by decompressing the folders ZFCb, ZFCc,... Corresponding to the banks in the folder FCa corresponding to the decompressed domain (re-determining the directory name or path name). Then, it is stored (updated) in the storage unit 21 (S303).

  When the control unit 20 of the server apparatus 2 receives a plurality of folders corresponding to domains having the same location ID (or the same minor ID and the later-described group ID) and different identification numbers, they are included in the same system. Can be recognized as data of a plurality of domains.

  In this way, when the communication device 1 exists in each layer, the upper layer communication device 1 corresponds to the upper and lower layers in the server apparatus 2 while preventing the lower layer data from being transmitted redundantly. It can be recognized as data. Similarly to the configuration in which one communication device 1 is connected to the domain, the server device 2 uses the data structure in which the state information obtained from the management device M in each hierarchy is matched to the hierarchical structure of the storage elements. Can be remembered.

The information displayed in FIG. 19 is based on data acquired by the communication device 1 via the management device M in the power storage module.

  The screens of the pages of each layer of the power storage module group L displayed in FIGS. 17 to 19 are examples, and are not aggregated as, for example, a domain, and the power storage module group L is configured by a plurality of banks arranged in parallel. If there is a plurality of banks (a plurality of banks shown in FIG. 4), the highest layer is displayed as a bank. If the power storage module group L is only composed of one bank, that is, for example, 16 power storage modules connected in series (FIG. 4), only the module information (FIG. 18) obtained from the corresponding communication device 1 Is displayed.

  As shown in FIGS. 14 to 19, in the communication device 1, data is hierarchized according to the hierarchical structure of the power storage elements and the connection form with other communication devices 1 and transmitted to the server device 2. It is possible to present information according to the hierarchical structure without manually setting the server device 2.

There is a possibility that information may need to be grouped, such as being sorted and managed by time.

  FIG. 20 is a diagram illustrating an example of a screen for accepting grouping. A web screen 330 shown in FIG. 20 includes first and second selection menus 337 and 338, a device selection screen 339, and a move button 340. The grouping screen includes a first selection menu 337 for selecting an editing source group (all devices in FIG. 20) and a second selection menu 338 for selecting an editing destination (move destination) group. Initially, the second selection menu 338 includes a first group and a group addition menu that can be selected. All communication devices 1 in the same system are initially included in the first group, and the identification information of each communication device 1 is stored in the storage unit 21 in association with the identification information (number) of the first group. It is. On the device selection screen 339, a list of communication devices 1 distributed to the group selected by the first and second selection menus 337 and 338 is displayed. The move button 340 receives the movement of the communication device 1 selected on the device selection screen 339. When a new grouping is desired, a group is added using the second selection menu 338 by operating the operation unit 34 of the client device 3. When the move button 340 for the communication device 1 is selected for the communication device 1 selected by the operation of the operation unit 34 of the client apparatus 3 among the communication devices 1 of the group selected by the first selection menu 337 The group selected in the second selection menu 338 can be moved. In the server device 2, the identification information of the moved communication device 1 is stored in the storage unit 21 in association with the identification information (number) of the destination group.

  In this way, the data transmitted from the communication device 1 is hierarchized so that the server apparatus 2 automatically obtains the hierarchized data, and the Web page that matches the hierarchical structure of the power storage module group L is stored in the server. It can be presented from the device 2. For a large-scale power storage system including a large number of power storage cells, it is preferable to display information in a hierarchical manner (breakdown) as in the domain level, bank level, module level, and cell level. Even when a very large number of power storage cells are included, it is not necessary to perform a manual setting operation for the hierarchical structure of the power storage module group L as described above.

  The server device 2 can present not only the power storage module group L having a hierarchical structure, but also information on power-related devices such as the power conditioner P. When a plurality of power conditioners P are connected in series, the communication device 1 is mounted / connected to a control unit of any one of the power conditioners P that is representative as described above. The communication device 1 connected to the representative power conditioner P includes data including the number of the power conditioners P connected by communication between the control units and the state of each power conditioner P according to the connection order. Is transmitted to the server device 2. By receiving this data, the server device 2 can automatically recognize the number of inverters P and the connection form and present information.

  The data structure that matches the connection form or the hierarchical structure cannot be stored only by transmitting data including the state of each power storage element or power-related device from the communication device 1 to the server device 2 in association with the identification information. . In this case, the server device 2 needs to store the relationship between the identification information by receiving a setting operation from the operator. Even if power storage elements (modules or cells) are simply connected in series, information such as the order of connection is the order of identification number 1, identification number 2, identification number 3,... If is not stored, information on each storage element according to the connection form cannot be presented. Furthermore, in the case of a hierarchical structure, display of information reflecting the hierarchical structure is impossible unless settings such as the identification numbers 4 and 5 hanging below the identification number 1 are made. On the other hand, the communication device 1 has already created a data structure corresponding to the connection form or hierarchical structure and then transmitted it. Even in the case of simple serial connection, the communication device 1 stores, for example, the identification number of the immediately upstream communication device 1 and the identification number of the downstream communication device 1, and based on these information The connected data is transmitted, and the server device 2 can store data and present information including the serial connection state of each power storage element or power-related device in that order.

  In the above-described embodiment, the description has been given of automatically presenting a hierarchical state for a power storage element having a hierarchical structure of domains and banks. The same processing can be applied to the case where the storage module group L in which a plurality of storage elements included in the uninterruptible power supply U and the rectifier D are connected in parallel.

  The embodiments disclosed above are illustrative in all respects and are not restrictive. The scope of the present invention is defined by the terms of the claims, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
