FIG. 5 is a flowchart for explaining an example of the operation of the user terminal based on the WEB page data acquired from the storage battery selection support device of one embodiment.
When the user operates the user terminal 20 to start the web browser and requests access to the storage battery selection support web page, the acquisition unit 25A of the control circuit 25 receives the request for web page access (step SB1 "Yes"). .

The acquisition unit 25A of the control circuit 25 accesses the server 10 and acquires the requested WEB page data from the server 10 (step SB2).
The display processing unit 25B of the control circuit 25 displays a storage battery selection support WEB page on the display unit 23 using the acquired WEB page data (step SB3). As described above, the user does not need to register as a member and can freely access the storage battery selection support web page.

FIG. 8 is a diagram showing an example of a display on a user terminal by the storage battery selection support device of one embodiment.
First, a function for the user to input operating conditions of a desired storage battery cell is displayed on the storage battery selection support WEB page. The storage battery selection support WEB page shown in FIG. 8 includes, for example, a button A1 for selecting the type of storage battery cell, an input field A2 for inputting charging/discharging conditions of the storage battery cell, and a button A4 for checking input contents. , is displayed.

The button A1 for selecting the type of storage battery cell may be able to select one from a plurality of types, or may be able to select a plurality of types at the same time. Further, the display processing unit 25B may display on the display unit 23 a function for selecting the use of the storage battery cell (or the system in which the storage battery cell is installed) instead of or together with the button A1. The display processing unit 25B can obtain, as operating conditions, the type of storage battery cell and charging/discharging conditions appropriate for the application selected by the user.

Input field A2 for inputting charging and discharging conditions can be entered, for example, by copying a list of times and charging and discharging power of storage battery cells (time history values of charging and discharging power) created using spreadsheet software. can. Note that the charging and discharging conditions may be a list of times and charging and discharging currents of storage battery cells (time history values of charging and discharging currents).

The "Check input content" button A4 becomes active (selectable state) when button A1 is selected and data is entered in input field A2, and once selected, the next user input It remains inactive (unselectable) until the information is changed.

The user operates the operation unit 22 to select the battery type displayed on the storage battery selection support WEB page, enters the charging/discharging conditions in the input field, and selects (clicks or presses) the "Check input contents" button A4. touch the screen).
When the user inputs the charging/discharging conditions (step SB4 "Yes"), the display processing unit 25B of the control circuit 25 checks the input information (step SB5).

The display processing unit 25B determines that the input information (charge/discharge condition) needs to be corrected when the information input by the user does not satisfy a predetermined condition (input condition) (step SB6 "Yes"). ”). For example, in the list of charge/discharge conditions input by the user, the display processing unit 25B corrects the input information when duplicate times are input or when the time that should be increased is decreased in chronological order. It is determined that it is necessary. Further, the display processing unit 25B determines that the input information needs to be corrected when the charging/discharging power of the storage battery cell exceeds a preset range. Further, the display processing unit 25B determines that the input information needs to be corrected when characters (characters other than numbers and mathematical symbols) that are not recognized as input for charging/discharging power are input.

When the display processing unit 25B determines that the input information needs to be corrected in step SB6, the display processing unit 25B corrects the input information so that it satisfies the conditions (step SB7). When the input information is corrected, the display processing unit 25B displays the correction details A3 on the storage battery selection support WEB page. In the example shown in FIG. 8, it is determined that the ○○th line, XXth line, and △△th line of the input list need to be corrected. A correction has been made to delete the information in the first line. The user can confirm the displayed modification content A3 and further modify the modified input information.
The display processing unit 25B displays a graph of the charging and discharging conditions modified in step SB7 or the charging and discharging conditions input by the user (step SB8).

FIG. 9 is a diagram illustrating an example of a display on a user terminal by the storage battery selection support device of one embodiment.
FIG. 9 shows an example of a graph A5 of charge/discharge conditions displayed on the storage battery selection support WEB page and a display A6 of completion of checking input contents and operation instructions.

Graph A5 of charging and discharging conditions is a graph in which the horizontal axis is time and the vertical axis is charging and discharging power of the storage battery cell. Graph A5 assumes that the storage battery cell is charged or discharged at a constant power value until the value is updated. For example, if the charging/discharging conditions are 20 (W) at time 10 (s) and -20 (W) at time 20 (s), the constant 20 (W) from 0 (s) to less than 10 (s) The output power is constant at -20 (W) during the period from 10 (s) to less than 20 (s). Note that the manner in which the charging and discharging power changes is not limited to this; for the above-mentioned charging and discharging conditions, the output power is constant at 0 (W) from 0 (s) to less than 10 (s), and the output power is constant at 10 (W). s) to less than 20 (s), the output power may be constant at 20 (W). Furthermore, for the charging and discharging conditions described above, the power changes linearly from 0 (W) to 20 (W) during the time from 0 (s) to less than 10 (s), and from 10 (s) to 20 (s). The power may be changed linearly from 20 (W) to -20 (W) for a time less than 20 (W).

When displaying the modified content, the display processing unit 25B may make the representation of the modified part different from the representation of the unmodified part. For example, when displaying the graph A5 of the charging/discharging conditions corrected in step SB7, the display processing unit 25B may display the corrected portion in a different color from other portions of the graph. As a result, the user can immediately recognize which part has been corrected by the color of the graph A5.

When the corrected charge/discharge condition is empty or only (0, 0) (step SB9 "Yes"), the display processing unit 25B waits for input of the charge/discharge condition from the user (step SB4). In this case, the calculation button A10 becomes inactive, and the display A6 indicating completion of checking input contents is not displayed.

When the corrected charge/discharge condition is not empty or only (0,0) (step SB9 "No"), display A6 indicating completion of input content check is displayed, and the environment temperature input area, initial SOC input area, calculation The button A10 is displayed in an active state (step SB10). For example, in display A6, a display (display of operation instructions) is made that guides the user to input information into the environmental temperature input area and the initial SOC input area and select the calculation button.

FIG. 10 is a diagram illustrating an example of a display on a user terminal by the storage battery selection support device of one embodiment.
The storage battery selection support WEB page displays a function for the user to input usage conditions for a desired storage battery cell. FIG. 10 shows an input area A7 for inputting the environmental temperature value displayed on the storage battery selection support web page, an input area A8 for inputting the initial SOC value, a disclaimer display A9, and a calculation button A10. An example is shown.

The input field is not limited to the above; for example, an input field may be provided for inputting a numerical value of the storage battery cell temperature instead of a numerical value for the environmental temperature, or an input field may be provided for inputting the capacity of the storage battery cell, etc. I don't mind.

Furthermore, by arranging the input area A7 and the input area A8 relatively close to the calculation button A10 (for example, within the range that fits on the screen), the user's operability is improved and input errors can be avoided.

The user enters the numerical value of the environmental temperature at which the storage battery cell is used in the input area A7, inputs the numerical value of the initial SOC in the input area A8, confirms and accepts the disclaimer, and selects the calculation button A10. The calculation button A10 is a means for the user to indicate that he or she has confirmed the input. At this time, the range in which the environmental temperature and initial SOC values can be input may be set in advance. Note that, for example, as shown in FIG. 10, the user's operability can be improved by making the exemption approval button and the calculation execution button common.

When the user selects the calculation button A10, the display processing unit 25B acquires the input values of the environmental temperature and the initial SOC (step SB11 "Yes"), and informs the server 10, which is a storage battery selection support device, of the type and charge of the storage battery cell. All input information including discharge conditions is transmitted (step SB12).
Note that calculations using the battery model will be explained in detail later.

When the model calculation unit 14C of the server 10 completes the execution of the simulation using the storage battery model and the creation of a graph of the simulation results, the communication circuit 21 of the user terminal 20 receives the graph of the calculation result and the message of the calculation result from the server 10. The display processing section 25B displays the contents on the display section 23 (step SB14).
Further, when the calculation by the server 10 is not completed, the display processing unit 25B receives an empty error graph and an error message from the server 10, and displays the empty graph and the error message as the result graph and calculation result message. 23 (step SB14).

FIG. 11 is a diagram illustrating an example of a display on a user terminal by the storage battery selection support device of one embodiment.
FIG. 11 shows a message that the calculation has been completed displayed on the storage battery selection support WEB page, a display A13 of information input by the user, a graph A11 of the time change of the voltage of the storage battery cell, and a graph A11 of the time change of the SOC of the storage battery cell. An example of the result graph of graph A12 is shown. The storage battery selection support WEB page in FIG. 11 displays a result graph for one storage battery cell, but if the user selects multiple storage battery cells in step SB4, the simulation results for multiple storage battery cells are displayed. It may also be displayed in a comparable manner.

Although not shown in the graphs A11 and A12 of the calculation results, the calculated period in which forced cooling of the storage battery cells was performed in the simulation by the server 10 may be shown. The user can check from the graphs A11 and A12 whether or not forced cooling of the storage battery cells is necessary, and if forced cooling is necessary, for how long.

By displaying the information input by the user (display A13) again, the user can check whether his/her input is correct.
The user checks the displayed result graph and message, and if, for example, a different simulation is to be performed (step SB15 "No"), the user returns to inputting the charge/discharge conditions (step SB4) and runs the simulation under other conditions. It can be carried out.

When the user confirms the displayed result graph and message and leaves the page (step SB16 "Yes"), the display processing unit 25B can display a function that accepts additional operations from the user. The display processing unit 25B may, for example, display a button for downloading the last simulation result in the form of text or table data, or for performing a more detailed simulation.

The display processing unit 25B may display a button for viewing (or presenting) a detailed explanation of a storage battery cell or storage battery system or a button for connecting to a recommendation system as an additional operation by the user, and may also display a button for connecting to a recommendation system. (Acquisition of means) You may display a button to connect to the page. By registering as a user, the user can obtain detailed information about the desired storage battery cell from the battery manufacturer at a later date.

Additionally, the display processing unit 25B may display an inquiry button for the user to send questions and requests regarding the simulation results and detailed information on the storage battery cells to the storage battery manufacturer as an additional user action. When the user selects the inquiry button, the display processing unit 25B may, for example, move to an inquiry page and display an inquiry form, start a chat screen with an operator, or start a mailer. A screen for sending an email to the battery manufacturer may be displayed, or a phone call to the operator may be made.

At this time, if the user consents, the display processing unit 25B may save the user's input information or collect the saved information. By recording and collecting the conditions of simulations performed by users, battery manufacturers will be able to perform more detailed simulations in accordance with users' wishes, and will be able to respond smoothly to user inquiries. can.

6 and 7 are flowcharts for explaining an example of the battery model calculation shown in FIG. 5.
First, the server 10, which is a storage battery selection support device, receives calculation condition data input by the user via the communication circuit 11 as described above, and the model calculation unit 14C reads these data (step SC1).

The model calculation unit 14C sets the temperature of the forced cooling refrigerant based on the conditions input by the user (step SC2). For the temperature of the forced cooling medium, for example, a value that is preset according to the environmental temperature value input by the user, the use of the storage battery cell, etc. can be used.

Subsequently, the model calculation unit 14C sets a forced cooling start temperature and a forced cooling end temperature based on the conditions input by the user and the temperature setting of the forced cooling refrigerant (step SC3). The forced cooling start temperature and the forced cooling end temperature are set according to, for example, the environmental temperature value input by the user, the type and use of the storage battery cell, and the like.

The model calculation unit 14C divides the calculation time step width into units of 0.1 seconds (step SC4).
Subsequently, the model calculation unit 14C selects an internal resistance function of the storage battery cell to be used depending on the type and purpose of the storage battery cell selected by the user (step SC5). The internal resistance function of the storage battery cell is set in advance depending on the type of storage battery cell, for example.

Subsequently, the model calculation unit 14C sets initial conditions for battery model calculation (step SC6). Note that user input information and data of various setting values such as initial conditions may be temporarily recorded in the memory.
Subsequently, the model calculation unit 14C sets parameters necessary for temperature calculation (step SC7). Parameters necessary for temperature calculation are set based on, for example, the type and purpose of the storage battery cell and the numerical value of the environmental temperature input by the user.

Subsequently, the model calculation unit 14C sets the upper limit voltage and lower limit voltage of the storage battery cell (step SC8), and the model calculation unit 14C roughly calculates the effective current of the storage battery cell using the internal resistance function of the storage battery cell described above. (Step SC9).
Subsequently, the model calculation unit 14C calculates the flow rate and flow velocity required for forced cooling (step SC10), and sets parameters necessary for forced cooling (step SC11).

Subsequently, the model calculation unit 14C sets the parameters of the equivalent circuit model of the storage battery cell (step SC12), and sets other necessary variables (step SC13).
The model calculation unit 14C starts a battery model calculation loop using the above set values (step SC14).

The model calculation unit 14C first obtains the time step size and the power value from the calculation condition data (step SC15). The model calculation unit 14C uses the acquired power value to calculate the current of the storage battery cell (step SC16).
Subsequently, the model calculation unit 14C calculates the voltage, SOC, and heat generation of the storage battery cell using the equivalent circuit model of the storage battery cell using the current of the storage battery cell and the like (step SC17).

Next, the model calculation unit 14C determines whether forced cooling is necessary based on the temperature of the storage battery cell (step SC18). The model calculation unit 14C determines that forced cooling is necessary when the temperature of the storage battery cell exceeds a forced cooling start temperature, which is a predetermined threshold, and calculates the temperature of the storage battery cell when forced cooling is performed. Calculate (step SC20). The model calculation unit 14C determines that forced cooling is unnecessary when the temperature of the storage battery cell is below the forced cooling end temperature which is a predetermined threshold, and calculates the temperature of the storage battery cell due to natural heat radiation (step SC19).

The model calculation unit 14C stores the above calculation results in a recording variable (step SC21).
The model calculation unit 14C determines whether any of the temperature, voltage, and SOC of the storage battery cell exceeds a preset calculation range (step SC22), and if none of them exceed the calculation range, the calculation end time is reached. It is determined whether it has been reached (step SC23). The model calculation unit 14C performs steps SC15 to SC21 until the temperature, voltage, and SOC of the storage battery cells are all within the calculation range and the calculation end time is reached.

If any of the temperature, voltage, and SOC of the storage battery cell exceeds the calculation range, or if the calculation end time is reached, the model calculation unit 14C performs graph creation processing from the calculation results so far (step SC24). ) and write out the graph (step SC25).

As described above, the user can access the storage battery selection support web page by operating the user terminal 20, and can easily learn the simulation results of the storage battery cells in a short time. Thereby, it is possible to determine whether the battery voltage and the like meet specifications under the conditions under which the user uses the storage battery cell, and whether or not temperature control is necessary. Furthermore, the user can perform additional operations after viewing the simulation results, and can also obtain detailed information.
