DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, a display control method according to an embodiment of the present disclosure will be described with reference to the drawings. The display control method according to the present embodiment is used to consider a combination of unit cells when combining a plurality of unit cells to form a battery pack. The battery pack constructed by the method according to the present embodiment is used as a storage battery in an EMS (Energy Management System), for example. In the present embodiment, a known storage battery is preferably used as the single cells constituting the battery pack. The storage battery is, for example, a used lithium-ion battery for automobiles.

[0010] In this embodiment, a terminal device is used to display information about a plurality of assembled batteries (e.g., combinations of cells) on a display unit. A user examines combination patterns of cells that constitute the assembled battery by visually checking the display unit. The combination patterns of cells may be suggested by the terminal device. A user visually checks the display unit to ascertain, for example, various pieces of information about the combinations of cells that constitute the assembled battery.

[0011] (Terminal device overview) FIG. 1 is a schematic block diagram showing a specific example of a functional configuration of a terminal device 10 (display control device) according to an embodiment. The terminal device 10 has a known configuration. The display control method according to the present embodiment is implemented using the known terminal device 10. The terminal device 10 is configured using an information device such as a smartphone, a tablet, a personal computer, or a dedicated device. The terminal device 10 includes a communication unit 11, an input unit 12, a display unit 13, an audio device 13a, a storage unit 14, and a control unit 15.

[0012] The communication unit 11 is a communication device. The communication unit 11 may be configured as, for example, a network interface. The communication unit 11 communicates data with other devices via a network according to the control of the control unit 15. The communication unit 11 may be a device that performs wireless communication or a device that performs wired communication.

[0013] The input unit 12 is configured using existing input devices such as a keyboard, a pointing device (mouse, tablet, etc.), a button, a touch panel, etc. The input unit 12 is operated by a user when inputting the user's instruction to the terminal device 10. The input unit 12 may be an interface for connecting the input device to the terminal device 10. In this case, the input unit 12 inputs an input signal generated in the input device in response to the user's input to the terminal device 10. The input unit 12 may be configured using a microphone and a voice recognition device. In this case, the input unit 12 acquires an acoustic signal generated by the user's speech, performs voice recognition on the words spoken by the user, and inputs character string information of the recognition result to the terminal device 10. The voice recognition process may be executed by the control unit 15. The input unit 12 may be configured in any way as long as it is configured to input the user's instruction to the terminal device 10.

[0014] The display unit 13 outputs information in a form that can be recognized by the user. The display unit 13 may be an image display device such as a liquid crystal display or an organic EL (Electro Luminescence) display. The display unit 13 may be an interface for connecting an image display device to the terminal device 10. In this case, the display unit 13 generates a video signal for displaying image data and outputs the video signal to the image display device connected to the display unit 13. The display unit 13 may be configured as a touch panel integrated with the input unit 12. The audio device 13a is a device that outputs information to a user in addition to the display unit 13. The audio device 13a is a device that outputs sound such as a speaker. The audio device 13a may be an interface for connecting an audio output device such as a speaker or a headphone to the terminal device 10. In this case, the audio device 13a generates an audio signal for reproducing audio data and outputs the audio signal to the audio output device connected to itself.

[0015] The storage unit 14 is configured using a storage device such as a magnetic hard disk device or a semiconductor storage device. The storage unit 14 stores data used by the control unit 15. The storage unit 14 stores data required when the control unit 15 performs processing. The storage unit 14 stores, for example, various types of information related to the battery pack. The various types of information related to the battery pack include, for example, battery pack current level information and battery pack future level information. Alternatively, the storage unit 14 may store various types of information related to a plurality of cells used in the battery pack. The various types of information related to the cells include, for example, cell current level information and cell future level information. Details of the various types of information related to the battery pack and the cells will be described later. Note that, instead of being stored in the storage unit 14, the various types of information may be stored, for example, on a server communicably connected to the terminal device 10.

[0016] The control unit 15 is configured using a processor such as a CPU (Central Processing Unit) and a memory (main storage device). The control unit 15 functions by the processor executing a program. All or part of the functions of the control unit 15 may be realized using hardware such as an ASIC (Application Specific Integrated Circuit), a PLD (Programmable Logic Device), or an FPGA (Field Programmable Gate Array). The above program may be recorded on a computer-readable recording medium. The computer-readable recording medium is, for example, a portable medium such as a flexible disk, a magneto-optical disk, a ROM, a CD-ROM, or a semiconductor storage device (e.g., an SSD: Solid State Drive), or a storage device such as a hard disk or a semiconductor storage device built into a computer system. The above program may be transmitted via an electric communication line.

[0017] The control unit 15 may execute the display control method according to the present embodiment, for example, by executing an application (program) installed in the device itself (terminal device 10). A specific example of such an application is an application provided to the terminal device 10 as a dedicated application for examining the combination of the above-mentioned single cells. Another specific example of such an application is a WEB browser application. Such an application may be installed in the terminal device 10 in advance, or may be downloaded each time the determination process is executed. For example, when the application is implemented as a WEB browser application, the terminal device 10 may download and execute the application from a device (for example, the WEB server itself or another server) designated by the WEB server in response to the terminal device 10 connecting to the specific WEB server. The control unit 15 operates according to the program of the application being executed.

[0018] The control unit 15 controls the terminal device 10 according to various information input by user operation and various information related to the plurality of cells used in the battery pack. For example, the control unit 15 generates screen data based on combination patterns of the cells constituting the battery pack and various information related to the plurality of cells, based on information input by the user operating the input unit 12 and various information related to the plurality of cells stored in the storage unit 14, and causes the display unit 13 to display the screen data. Alternatively, the control unit 15 may generate audio data based on the above-mentioned information and cause the audio device 13a to output the audio data.

[0019] FIG. 2 is a schematic block diagram showing a specific example of a functional configuration of the control unit 15 according to the embodiment. As shown in FIG. 2, the control unit 15 includes a communication control means 15a, an input information processing means 15b, a storage control means 15c, an information acquisition means 15d, a calculation means 15e, an examination means 15f, and a display control means 15g.

[0020] The communication control means 15a is a part of the control unit 15 that controls the communication unit 11. The communication unit 11 functions under the control of the communication control means 15a. The input information processing means 15b is a part of the control unit 15 that accepts various information input by a user using the input unit 12. The information accepted by the input information processing means 15b is used, for example, for calculation processing by the calculation means 15e and for display control processing by the display control means 15g.

[0021] The memory control means 15c is a part of the control unit 15 that controls the memory unit 14. The memory control means 15c stores, for example, the information acquired by the information acquisition means 15d, the calculation result by the calculation means 15e, the examination result by the examination means 15f, and the judgment result in the judgment step St3 (described later) in the memory unit 14. The information acquiring means 15d is a part of the control unit 15 that acquires current cell condition information. The current cell condition information includes, for example, information related to various measurement data output from sensors built into each of the cells, usage history, etc. The information on the cells thus read by the information acquiring means 15d may be stored in the memory unit 14 by, for example, the memory control means 15c.

[0022] The calculation means 15e is a part of the control unit 15 that calculates the future battery level information, the current battery level information, and the future battery level information. The calculation means 15e calculates each of these level information using, for example, information input by a user received by the input information processing means 15b and the current battery level information acquired by the information acquisition means 15d. The calculation results by the calculation means 15e may be stored in the memory unit 14 by, for example, the memory control means 15c.

[0023] The review means 15f is a part of the control unit 15 that reviews the combination of cells in the assembled battery. The review means 15f reviews the combination of cells in the assembled battery, for example, using input information by a user received by the input information processing means 15b, current cell condition information acquired by the information acquisition means 15d, and the calculation result by the calculation means 15e. The review result by the review means 15f may be stored in the memory unit 14 by the memory control means 15c, for example.

[0024] The display control means 15g is a part of the control unit 15 that generates various information to be displayed on the display unit 13 and displays it on the display unit 13. The display control means 15g converts, for example, a first assembled battery image AB1 and a second assembled battery image AB2, current cell condition information, future cell condition information, current assembled battery condition information, and future assembled battery condition information, into information that can be displayed on the display unit 13, and transmits it to the display unit 13.

[0025] (Contents displayed on the display) In this embodiment, information about two assembled batteries, a first assembled battery and a second assembled battery, is displayed on the display unit 13. The first assembled battery includes a plurality of first cells. In other words, the first assembled battery is composed of a plurality of first cells. The second assembled battery includes a plurality of second cells. In other words, the second assembled battery is composed of a plurality of second cells. In this embodiment, information about the first assembled battery and information about the second assembled battery are displayed on the display unit 13. The information about the first assembled battery includes information about the multiple first cells. The information about the second assembled battery includes information about the multiple second cells. The user checks the information about the first assembled battery and the information about the second assembled battery on the display unit 13 and considers the combination of the batteries. In the following description, when there is no need to distinguish between the first assembled battery and the second assembled battery, they will be referred to as the assembled battery, and when there is no need to distinguish between the first and second cells, they will be referred to as the cells.

[0026] FIG. 3 is a first example of a screen displayed on the display unit 13. As shown in FIG. FIG. 4 is a second example of a screen displayed on the display unit 13. In FIG. FIG. 5 is a third example of a screen displayed on the display unit 13. In FIG. As shown in Figs. 3 to 5, the display unit 13 displays, for example, a first assembled battery image AB1, a second assembled battery image AB2, a coordinate system AX, and a setting section S. The various pieces of information displayed on the display unit 13 in this manner are generated by the display control means 15g as described above. In this embodiment, the first assembled battery image AB1 and the second assembled battery image AB2 displayed on the display unit 13 refer to images that display information related to the first assembled battery and the second assembled battery, respectively. The coordinate system AX is an image (for example, a two-dimensional graph) that shows the relationship between the two assembled batteries. The setting section S is an image that sets and displays preconditions for displaying the various pieces of information.

[0027] In the illustrated example, the first assembled battery image AB1, the second assembled battery image AB2, and the coordinate system AX are arranged side by side in the left-right direction of the display unit 13. The setting unit S is arranged below the first assembled battery image AB1, the second assembled battery image AB2, and the coordinate system AX, which are arranged side by side in the left-right direction. However, the positional relationship between the first assembled battery image AB1, the second assembled battery image AB2, the coordinate system AX, and the setting unit S is not limited to this.

[0028] The first assembled battery image AB1 and the second assembled battery image AB2 displayed on the display unit 13 refer to an arrangement of multiple images showing information about the cells (first cell, second cell) so that the combination of multiple cells can be grasped.

[0029] 3 to 5, the first assembled battery image AB1 includes a plurality of first cell images B1. The second assembled battery image AB2 includes a plurality of second cell images B2. The first cell images B1 and the second cell images B2 refer to images displayed on the display unit 13 and show information relating to the first cells and the second cells, respectively.

[0030] In this embodiment, the first assembled battery and the second assembled battery are configured by connecting four battery combinations in series, each of which has three unit cells connected in parallel. The display unit 13, as shown in Figs. 3 to 5, typically displays the above-mentioned connection configuration between the unit cells. The above-mentioned assembled battery configured by connecting three unit cells in parallel is called a unit assembled battery. It can also be said that the first assembled battery and the second assembled battery are configured by connecting four unit assembled batteries in series. However, when configuring the assembled battery, any number of unit cells may be connected in parallel (two or four or more unit assembled batteries may be connected in parallel in a unit assembled battery), or any number of unit assembled batteries may be connected in series (two, three, or five or more unit assembled batteries may be connected in series). Alternatively, in the unit battery pack, a plurality of unit cells may be connected in series, or a plurality of unit batteries, each of which is made up of a plurality of unit cells connected in series, may be connected in parallel.

[0031] In the first assembled battery image AB1 and the second assembled battery image AB2, unit assembled battery images AB, which are images showing unit assembled batteries, are arranged side by side in the vertical direction of the display unit 13. In each of the unit assembled battery images AB, a first unit cell image B1 and a second unit cell image B2, which show respective unit cells constituting the unit assembled battery, are arranged side by side in the horizontal direction of the display unit 13.

[0032] As shown in Fig. 3 to Fig. 5, each of the plurality of unit cells is given an identification number, and the identification number is displayed on each first unit cell image B1 and each second unit cell image B2. For example, in the example of the first assembled battery shown in Fig. 3, each of the first unit cells is given an identification number from ID: 001 to 012, and is displayed on the first unit cell image B1. This allows the user to grasp various types of information about each of the plurality of first unit cells for each individual first unit cell. In the example shown in FIG. 3, the cells included in the first assembled battery and the cells included in the second assembled battery are the same. The arrangement of the cells is different between the first assembled battery and the second assembled battery. That is, in this embodiment, the first assembled battery and the second assembled battery have the same plurality of first cells and the same plurality of second cells. The arrangement of the first assembled battery and the arrangement of the second assembled battery are different. The user can understand the details of the first and second cells based on the IDs of the cells displayed in the first cell image B1 or the second cell image B2.

[0033] In this embodiment, the user visually grasps various pieces of information related to the multiple first cell images B1 included in the first assembled battery image AB1 and the multiple second cell images B2 included in the second assembled battery image AB2, which are displayed on the display unit 13. In addition to the identification numbers, the display unit 13 further displays various pieces of information described below related to the first cell images B1 and the second cell images B2. Note that in the illustrated example, the various pieces of information are displayed above and to the right of the identification numbers in the first cell image B1 and the second cell image B2, respectively, but the display positions are not limited to this. In this embodiment, the information on each of the plurality of unit cells includes, for example, unit cell current condition information and unit cell future condition information. The unit cell current condition information and unit cell future condition information are displayed corresponding to each of the plurality of unit cells.

[0034] The current cell level information is current level information for the cell. In this embodiment, the current state refers to the time when the display control method according to this embodiment is implemented. The current state information is, for example, various information related to the cell at the time when the display control method according to this embodiment is implemented. Each of the plurality of current cell condition information indicates the current storage capacity, current deterioration level, current maximum output, or current remaining capacity of the cell. In this embodiment, these various types of information are acquired by, for example, appropriately reading information on various measurement data output from sensors built into each of the cells, usage history, etc., by the information acquisition means 15d. The acquired information may be stored in the memory unit 14 of the terminal device 10 by, for example, the memory control means 15c.

[0035] In this embodiment, the storage capacity is expressed, for example, in kWh (kilowatt hours). The deterioration level is, for example, the ratio of the current or future storage capacity to the storage capacity in a new state. The deterioration level is expressed, for example, in % (percentage). The degree of deterioration may be displayed, for example, as a graph that allows the change in the deterioration rate over time to be confirmed. The maximum output is expressed, for example, in kW (kilowatts). The remaining capacity is expressed, for example, in % (percentage). In this embodiment, whether the power storage capacity, the deterioration level, the maximum output, or the remaining capacity level is displayed on the display unit 13 is appropriately determined by the user (details will be described later).

[0036] The cell future level information is information about the future level of the cell. In this embodiment, the future level information is, for example, a predicted value of various information related to the cell after a predetermined period of time has elapsed from the time when the display control method according to this embodiment is implemented. In this embodiment, the predetermined period of time is specified by the user (details will be described later).

[0037] Each of the plurality of pieces of unit cell future condition information indicates the future storage capacity, future deterioration degree, future maximum output, or future remaining capacity of the unit cell. These various pieces of information are output, for example, from a sensor or the like built into each unit cell, and are obtained by appropriately calculating the degree after a predetermined period of time has elapsed using the calculation means 15e based on the information stored in the storage unit 14 of the terminal device 10. The information calculated in this manner may be displayed on the display unit 13 as unit cell future condition information by the display control means 15g, or may be stored in the storage unit 14 of the terminal device 10 by the storage control means 15c.

[0038] 3, the current cell condition information and the future cell condition information are arranged side by side with a symbol (in the illustrated example, a slash (" / ")) between them in the first cell image B1 and the second cell image B2. Of the two pieces of information arranged side by side, the information on the left is the future cell condition information, and the information on the right is the current cell condition information.

[0039] In the example shown in Fig. 4, instead of showing both the current cell condition information and the future cell condition information, only the future cell condition information is shown, and in the example shown in Fig. 5, only the current cell condition information is shown. The display can be switched by, for example, the user operating a display time setting unit S3, which will be described later.

[0040] In this embodiment, the user can grasp various pieces of information relating to the first and second assembled batteries by visually checking the first assembled battery image AB1 and the second assembled battery image AB2 displayed on the display unit 13 by the display control means 15g. The display unit 13 displays various pieces of information relating to the first and second assembled batteries, as described below. Note that, in the illustrated example, the various pieces of information are arranged above the unit assembled battery images AB on the display unit 13. In this embodiment, the information regarding each of the first assembled battery and the second assembled battery includes, for example, assembled battery current level information and assembled battery future level information.

[0041] The current battery pack condition information is information on the current condition of the battery pack. The current condition information of the battery pack indicates, for example, the current storage capacity of the battery pack, the current degree of deterioration, the current maximum output, or the current degree of remaining capacity. In this embodiment, the battery pack current level information corresponding to the battery pack is obtained by multiplying the lowest value of the current level information of each of the multiple unit battery packs connected in series in the battery pack by the number of unit battery packs connected in series. For example, if the lowest value of the storage capacity of the multiple unit battery packs is 100 kWh and the number of unit battery packs is 4, the battery pack current level information corresponding to the battery pack is 100 kWh x 4 = 400 kWh. The current level information corresponding to each of the unit assembled batteries used in the above calculations is obtained by the calculation means 15e adding up the current cell level information of each of the multiple unit cells included in the unit assembled battery and connected in parallel. That is, the battery assembly current condition information corresponding to the first battery assembly is obtained by summing up the current cell condition information of the first cells (current cell condition information of first cells) in each of the multiple unit battery assemblies included in the first battery assembly and then performing the above-mentioned calculation.The battery assembly current condition information corresponding to the second battery assembly is obtained by summing up the current cell condition information of the second cells (current cell condition information of second cells) in each of the multiple unit battery assemblies included in the second battery assembly and then performing the above-mentioned calculation.

[0042] The battery pack future level information is information on the future level of the battery pack. The battery pack future level information indicates, for example, the future power storage capacity, the future degree of deterioration, the future maximum output, or the future remaining capacity of the battery pack. In this embodiment, the battery pack future level information corresponding to the battery pack, similar to the battery pack current level information described above, is obtained by multiplying the lowest value of the future level information held by each of the multiple unit battery packs connected in series in the battery pack by the number of unit battery packs connected in series. The future level information corresponding to each of the unit battery packs used in the above calculation is obtained by the calculation means 15e adding up the unit cell future level information of each of the multiple unit cells included in the unit battery pack and connected in parallel. That is, the battery assembly future level information corresponding to the first battery assembly is found by summing up the respective cell future level information of the first cells (first cell future level information) in each of the multiple unit battery assemblies included in the first battery assembly and then performing the above-mentioned calculation.The battery assembly future level information corresponding to the second battery assembly is found by summing up the respective cell future level information of the second cells (second cell future level information) in each of the multiple unit battery assemblies included in the second battery assembly and then performing the above-mentioned calculation.

[0043] 3, the assembled battery current condition information and the assembled battery future condition information are arranged side by side with a symbol (in the illustrated example, a slash (" / ")) between them in the first cell image B1 and the second cell image B2. Of the two pieces of information arranged side by side, the information on the left is the assembled battery future condition information, and the information on the right is the assembled battery current condition information.

[0044] In the example shown in Fig. 4, instead of showing both the current battery pack level information and the future battery pack level information, only the future battery pack level information is shown, and in the example shown in Fig. 5, only the current battery pack level information is shown. The display can be switched by, for example, the user operating the display time setting unit S3.

[0045] Hereinafter, a method for calculating the current level information of a battery pack corresponding to a battery pack based on the current level information of each of the plurality of single cells included in the battery pack will be described, taking the storage capacity of the battery pack as an example. The method for calculating the current level information of the battery pack is similar for the deterioration level, maximum output, and remaining capacity. As described above, the deterioration level and remaining capacity are calculated in units of %, so when performing these calculations, it is preferable to appropriately adjust the units of each parameter used in the calculation (for example, from kW (kilowatts) to kWh (kilowatt hours)). The method for calculating the future level information of a battery pack corresponding to a battery pack based on the future level information of each of the plurality of single cells included in the battery pack is also similar.

[0046] Here, as described above, the first assembled battery and the second assembled battery are configured by connecting four combinations of unit cells in series, each of which is made up of three cells connected in parallel. At this time, the calculation means 15e first calculates the total value of the current and future storage capacity of each combination of three unit cells connected in parallel (unit assembled battery). For example, in the unit assembled battery image AB in the first assembled battery image AB1 shown in FIG. 3, the total value of each of the current and future storage capacities is displayed on the right side of the image. In the illustrated example, the total value of each of the current and future storage capacities is arranged left and right with a symbol (in the illustrated example, " / " (slash)) between them. Of the two pieces of information arranged left and right, the information on the left is the future storage capacity, and the information on the right is the current storage capacity. For example, the current storage capacity of the cells with IDs: 001 to 003 included in the unit battery corresponding to the unit battery image AB located at the top of the first battery pack image AB1 is 260 kWh, and the future storage capacity is 200 kWh. The storage capacity of the first assembled battery and the second assembled battery is calculated by multiplying the smallest total value of the storage capacity calculated for each combination of unit assembled batteries that constitute the first assembled battery and the second assembled battery by the number of unit assembled batteries. That is, for example, among the unit battery packs corresponding to the multiple unit battery pack images AB shown in the first battery pack image AB1, the minimum current storage capacity is 200 kWh, and the minimum future storage capacity is 150 kWh. Note that this information may be displayed as "minimum value" above the unit battery pack images AB in the first battery pack image AB1. The storage capacity of the first assembled battery is a numerical value obtained by multiplying the above-mentioned "minimum value" by 4, which is the number of unit assembled batteries. That is, in the first assembled battery shown in the first assembled battery image AB1, the current storage capacity is 800 kWh, and the future storage capacity is 600 kWh. This information may be displayed as "storage capacity" above the unit assembled battery images AB in the first assembled battery image AB1.

[0047] In addition to the above information, a numerical value obtained by adding up the respective storage capacities of the unit battery packs corresponding to the plurality of unit battery pack images AB shown in the first battery pack image AB1 may be displayed above the unit battery pack images AB. This information may be displayed as a "total value" above the unit battery pack images AB in the first battery pack image AB1. For example, in the first battery pack image AB1, the current "total value" is 910 kWh, and the future "total value" is 700 kWh. The "total value" may be displayed so that the user can grasp the unused capacity of the plurality of unit battery packs included in the first battery pack by comparing it with the storage capacity of the first battery pack calculated as described above.

[0048] Note that while Figure 3 shows both the current and future storage capacity, Figure 4 shows only the future storage capacity, and Figure 5 shows only the current storage capacity. In the example shown in Fig. 3, the current and future storage capacities of the first assembled battery and the second assembled battery are arranged side by side with a symbol (in the illustrated example, " / " (slash)) between them. Of the two pieces of information arranged side by side, the information on the left is the future storage capacity, and the information on the right is the current storage capacity. For example, the current storage capacity of the first assembled battery is 800 kWh, and the future storage capacity is 600 kWh. The current storage capacity of the second assembled battery is 840 kWh, and the future storage capacity is 640 kWh. In the examples shown in Figs. 3 and 4, the future storage capacity indicated by the first assembled battery image AB1 is 600 kWh, and the future storage capacity indicated by the second assembled battery image AB2 is 640 kWh. In the examples shown in Figs. 3 and 5, the current storage capacity indicated by the first assembled battery image AB1 is 800 kWh, and the current storage capacity indicated by the second assembled battery image AB2 is 840 kWh. In this manner, in the present embodiment, in terms of both the future level information and the current level information, the second assembled battery has a higher performance than the first assembled battery.

[0049] In the coordinate system AX displayed on the display unit 13, one axis corresponds to the assembled battery future condition information, and the other axis corresponds to the assembled battery current condition information. As shown in Figs. 3 to 5, the horizontal axis of the coordinate system AX corresponds to the current level information of the battery pack. As the horizontal axis of the coordinate system AX moves away from the origin, the current performance of the battery pack becomes higher. The vertical axis of the coordinate system AX corresponds to the future level information of the battery pack. As the vertical axis of the coordinate system AX moves away from the origin, the future performance of the battery pack becomes higher. 3 to 5, battery assembled future level information and battery assembled current level information corresponding to the first battery assembled, and battery assembled future level information and battery assembled current level information corresponding to the second battery assembled are superimposed on the coordinate system AX (details will be described later). The battery assembled future level information and battery assembled current level information corresponding to the first battery assembled are displayed as a first point on the coordinate system AX. The battery assembled future level information and battery assembled current level information corresponding to the second battery assembled are displayed as a second point on the coordinate system AX.

[0050] The setting section S displayed on the display unit 13 is a section (interface) for setting information to be displayed on the display unit 13. The user inputs appropriate information to the setting section S, for example, via the input unit 12. The various pieces of information input to the setting section S are accepted by the input information processing means 15b, and are used, for example, in calculation processing by the calculation means 15e, review processing by the review means 15f, and display control processing by the display control means 15g. As a result, the information displayed on the display unit 13 changes appropriately. 3 to 5, the setting unit S includes a predetermined period setting unit S1, a storage capacity setting unit S2, a display time setting unit S3, and a display information setting unit S4. The positional relationship between the predetermined period setting unit S1, the storage capacity setting unit S2, the display time setting unit S3, and the display information setting unit S4 is not limited to the relationship shown in the drawings.

[0051] The predetermined period setting section S1 is a section for setting a predetermined period when displaying the cell future level information and the battery pack future level information. For example, the user uses the input section 12 to select the predetermined period setting section S1 displayed on the display section 13 and input the number of years related to the predetermined period. In the example shown in Figs. 3 and 4, the predetermined period is set to 5 years. The predetermined period may be 1 year, 10 years, or any other number of years, and may be not limited to years but may be months, weeks, or days. The cell future level information and the battery pack future level information are calculated by the calculation means 15e, for example, based on the predetermined period thus set.

[0052] The power storage capacity setting section S2 (constraint condition setting section) is a section for setting the power storage capacity of the assembled battery or the unit assembled battery. For example, the user uses the input section 12 to select the power storage capacity setting section S2 displayed on the display section 13 and inputs the power storage capacity required for the assembled battery. The power storage capacity is, for example, the amount of power that can be stored per unit time. In the example shown in Figs. 3 to 5, the minimum power storage capacity of the unit assembled battery is set to 200 kWh. At this time, since the assembled battery is made up of four unit assembled batteries in this embodiment, the power storage capacity of the assembled battery is set to 200 kWh x 4 = 800 kWh. In this embodiment, the examining means 15f determines the combination of the single cells so as to satisfy the storage capacity thus set. Note that with respect to the storage capacity (storage capacity), the charge amount (charging capacity) and the discharge amount (discharging capacity) may be set separately. In this embodiment, the charge and discharge amounts are the constraint conditions for the combination of the assembled batteries, but other parameters may be used as the constraint conditions instead of the charge and discharge amounts.

[0053] The display time setting unit S3 is a unit for specifying whether to display the current level information of the single cell and the current level information of the battery pack on the display unit 13, or the future level information of the single cell and the future level information of the battery pack. For example, the user uses the input unit 12 to select the display time setting unit S3 displayed on the display unit 13 and specify which of the above information is to be displayed on the display unit 13. In the example shown in FIG. 3, as "future, present" is displayed in the display time setting unit S3, it is set to display both the current level information and the future level information of the single cell and the battery pack. In this case, it is preferable that it is possible to separately set which of the current and future performance of the battery pack is to be considered preferentially in the examination step St5 described later. For example, in the example shown in FIG. 3, as "(present)" is displayed next to the display of "future, present", it is set to consider the current performance of the battery pack preferentially. In the example shown in FIG. 4, as "future" is displayed in the display time setting unit S3, it is set to display only the future level information of the single cell and the battery pack. In this case, the future performance of the battery pack may be considered preferentially in the examination step St5. In the example shown in Fig. 5, as "Current" is displayed in the display time setting unit S3, it is set to display only the current level information of the cells and the battery pack. In this case, the current performance of the battery pack may be considered preferentially in the examination step St5. The display control means 15g causes the display unit 13 to display information desired by the user based on the information input by the user.

[0054] The display information setting section S4 is a section for specifying which of the power storage capacity, the deterioration degree, the maximum output, or the remaining capacity of the cells and the battery pack is to be displayed on the display section 13. The user, for example, uses the input section 12 to select the display information setting section S4 displayed on the display section 13 and specifies which of the above information is to be displayed on the display section 13. In the example shown in Figs. 3 to 5, the display information is set to display the power storage capacity of the cells and the battery pack. For example, the display section 13 may display "Capacity" next to the numerical value of the power storage capacity to indicate that the power storage capacity is being displayed. The display control means 15g causes the display section 13 to display information desired by the user based on the information input by the user.

[0055] (Display control method) Next, a display control method according to this embodiment will be described. FIG. 6 is a flow chart of a display control method according to the embodiment. The display control method of this embodiment includes an input step St1, a designation step St2, a judgment step St3, an identification step St4, a consideration step St5, an alert step St6, a notification step St7, a first display control step St8, a second display control step St9, a third display control step St10, and a superimposed display control step St11.

[0056] The input step St1 is a step in which predetermined period information indicating a predetermined period is input. The input of the predetermined period information is performed by a user. Specifically, for example, the user inputs the predetermined period information to the predetermined period setting unit S1 via the input unit 12. The information input by the user in this manner is accepted by the input information processing means 15b. The predetermined period information (e.g., 5 years) input by the user is displayed in the predetermined period setting section S1 of the display unit 13, as shown in Figs. 3 and 4. The predetermined period information is reflected in the future time of the cell future degree information. That is, the future time corresponding to the degree indicated by the first cell future degree information and the future time corresponding to the degree indicated by the second cell future degree information correspond to the time after the passage of the predetermined period indicated by the predetermined period information input in input step St1. The predetermined period information input in input step St1 is used to calculate the cell future degree information of each of the first cell and the second cell, and the battery assembled future degree information of each of the first battery pack and the second battery pack. Specifically, for example, if the user inputs the predetermined period as five years, the first cell future degree information and the second cell future degree information are output as information relating to the degree five years from now.

[0057] The designation step St2 is a step in which future information indicating the future or present information indicating the present is designated. That is, in the designation step St2, it is designated whether current cell level information and current battery pack level information are to be displayed on the display unit 13, future cell level information and future battery pack level information are to be displayed, or both are to be displayed. In the designation step St2, the user designates which of the above information is to be displayed on the display unit 13 by operating the display time setting unit S3 using the input unit 12. The information input by the user in this manner is accepted by the input information processing means 15b.

[0058] The determination step St3 is a step for determining whether future information or present information is specified in the designation step St2. That is, in the determination step St3, for example, the display control means 15g determines whether the information input by the user in the designation step St2 is future information, present information, or both. Specifically, as shown in Fig. 6, in the determination step St3, first, it is determined whether or not the user has specified future information (step St3a), and then it is determined whether or not the user has specified present information (step St3b). If the user specifies future information (St3a: YES), the storage control means 15c stores information indicating that the user has specified future information in the storage unit 14 (step St3a1). If the user does not specify future information (St3a: NO), the above-mentioned process is not performed. If the user specifies the current information (St3b: YES), the storage control means 15c stores the fact that the user specified the current information in the storage unit 14 (step St3b1). If the user does not specify the current information (St3b: NO), the above-mentioned process is not performed. In the above process, when the user specifies both the future information and the present information, a specification as to whether the present or future performance of the battery pack is to be given priority in the consideration step St5 may be separately accepted. Such a specification may be made by the user operating the display time setting unit S3. Also, such a specification may be stored in the storage unit as appropriate in the above step St3a1 or step St3b1. The determination result of the above-mentioned determination step St3 is reflected in, for example, the display content on the display unit 13 in the first display control step St8, the second display control step St9, or the third display control step St10. Depending on the determination result of the determination step St3, the calculation means 15e may determine which of the cell future level information, the battery pack current level information, and the battery pack future level information to calculate.

[0059] The identification step St4 is a step in which battery pack information indicating a battery pack including a plurality of cells is identified. More specifically, the identification step St4 is a step in which the user identifies a part of the combination of cells in the battery pack. For example, the user uses the input unit 12 to identify the IDs of the cells to be associated with the first cell image B1 or the second cell image B2 in the first battery pack image AB1 or the second battery pack image AB2, respectively. Note that, before the user identifies the IDs, the first cell image B1 and the second cell image B2 may display only a frame (template) with the ID blanked, and the user may specify the IDs by operating the frame. The information input by the user in this manner is accepted by the input information processing means 15b. By the user specifying some of the combinations of the cells, the reviewing means 15f can review combinations other than the combinations of the cells specified by the user. Alternatively, in the specification step St4, the user may specify all of the combinations of the cells in the assembled battery. In this case, the information displayed on the display unit 13 may be the result of reviewing the quality of the assembled battery based on the combinations specified by the user. Note that in the specification step St4, the user does not need to specify any IDs of the cells. Furthermore, in the identification step St4, the user may, for example, identify all combinations of the first cells in the first assembled battery, and not identify any combinations of the second cells in the second assembled battery.

[0060] The examining step St5 is a step in which the examining means 15f examines the information to be displayed on the display unit 13 based on the information on the respective levels of the plurality of unit cells and various information input by the user. In the examining step St5, the examining means 15f may examine, for example, the combination of the cells in the first assembled battery and the second assembled battery. In the examining step St5, for example, the examining means 15f examines the combination of the cells other than the combination of the cells specified by the user in the specifying step St4. In the present embodiment, the consideration of the combination of the unit cells may be determined based on, for example, a previously prepared algorithm. The consideration of the combination of the unit cells may be determined by artificial intelligence. The consideration of the combination of the unit cells may be determined by incorporating the results of consideration by an external function. The consideration of the combination of the unit cells may be optimized by machine learning or the like.

[0061] Here, the first assembled battery image AB1 displayed on the display unit 13 shows one example of a combination of the first cell images B1 considered in the consideration step St5. The second assembled battery image AB2 displayed on the display unit 13 shows one example of a combination of the second cell images B2 considered in the consideration step St5. That is, in the consideration step St5, the consideration means 15f may consider two example combinations of cells. It is preferable for the user to adopt a battery pack including a combination of cells that is more suited to the purpose from the two example combinations of cells considered in this way.

[0062] When considering a combination of second cells in the second assembled battery, (1) at least one of the plurality of second cell future degree information is determined based on one of (2-1) assembled battery future degree information corresponding to the first assembled battery and (2-2) at least one of the plurality of first cell future degree information. In other words, the (1) second cell future degree information may be determined based on (2-1) assembled battery future degree information corresponding to the first assembled battery, and the (1) second cell future degree information may be determined based on the (2-2) first cell future degree information. More specifically, it is as follows. Here, in the examination step St5, the combination of the second cells in the second assembled battery is examined so that the performance (e.g., power storage capacity) of the second assembled battery exceeds the performance of the first assembled battery. At this time, the combination of the second cells in the second assembled battery (corresponding to the above (1)) is determined based on, for example, the performance related to the battery assembled future level information corresponding to the first assembled battery (corresponding to the above (2-1)). Alternatively, the combination of the second cells in the second assembled battery (corresponding to the above (1)) may be determined based on the performance related to the cell future level information corresponding to the first cells included in the first assembled battery (corresponding to the above (2-2)).

[0063] For example, when future information is specified in the specification step St2, the future performance of the battery pack may be considered preferentially in the consideration step St5 over the current performance of the battery pack. In other words, by suppressing the amount of deterioration of the battery pack due to future variations in deterioration of the cells, it may be possible to suppress the number of times that the cells are replaced due to future changes in the combination of the cells or replacement of the cells.

[0064] For example, when the current information is specified in the specification step St2, the current performance of the battery pack may be considered preferentially over the future performance of the battery pack in the consideration step St5. In other words, by setting the current performance of the battery pack high, it may be possible to carry out the current electricity trading on a large scale, thereby making it possible to increase the profit of the electricity trading.

[0065] For example, when both future information and present information are specified in the specification step St2, priority may be given to achieving both the present and future performance of the battery pack in the consideration step St5. In other words, the combination of cells may be considered with priority given to the overall workload during the usage period of the first or second battery pack. Alternatively, even when both future information and present information are specified in the specification step St2, priority may be given to either the present or future performance of the battery pack.

[0066] In this embodiment, the difference between the level indicated by the battery pack current level information corresponding to the first battery pack and the level indicated by the battery pack future level information corresponding to the first battery pack is equal to or less than a predetermined threshold. That is, the difference (degree of deterioration) between the current performance and the future performance of the first battery pack is set to be equal to or less than a predetermined threshold that is arbitrarily set. This makes it possible to prevent the degree of deterioration from the current performance to the future performance from becoming too large when considering the combination of the first cells in the first battery pack.

[0067] The notification step St6 is a step of notifying the user of a message for urging the user to re-input the predetermined threshold value when the degree indicated by the battery pack future degree information or the battery pack current degree information corresponding to the first battery pack is not equal to or greater than the predetermined threshold value input by the user. In this embodiment, the predetermined threshold value input by the user is, for example, a numerical value of the storage capacity set by the user in the storage capacity setting unit S2. In this embodiment, before the notification step St6, in a comparison step St5.5 shown in FIG. 6, the degree indicated by the assembled battery future level information or the assembled battery current level information corresponding to the first assembled battery is compared with a predetermined threshold value input by the user. In this way, the display control means 15g judges whether or not it is possible to reach the storage capacity input by the user by a combination of selectable single cells. It should be noted that whether the notification step St6 is performed based on the assembled battery future level information or the assembled battery current level information may be determined as follows. For example, when future information is specified in the designation step St2, the notification step St6 may be performed based on the assembled battery future level information, and when current information is specified in the designation step St2, the notification step St6 may be performed based on the assembled battery current level information. Below, a case where future information is specified in the designation step St2 will be described, and a case where current information is specified will not be described as being the same as the case where future information is specified. For example, when considering a combination of cells in a battery pack, if the storage capacity input by the user cannot be reached by a selectable combination of cells (St5.5: YES), the notification step St6 is performed. That is, the display unit 13 is caused to display that the storage capacity should be changed to a capacity that can be reached by a selectable combination of cells. For example, the storage capacity setting unit S2 is caused to blink. Alternatively, the storage capacity setting unit S2 may be displayed in a color different from other areas of the display unit 13. When considering a combination of cells in a battery pack, if the storage capacity input by the user can be reached by a selectable combination of cells (St5.5: NO), the notification step St6 is not performed.

[0068] In the notification step St7, a message for encouraging replacement of one of the plurality of first cells is notified to the user. In the notification step St7, the message is notified when a difference between the degree indicated by the first cell future degree information corresponding to one of the plurality of first cells and the degree indicated by the first cell future degree information corresponding to a different one of the plurality of first cells is equal to or greater than a predetermined threshold. For example, the display control means 15g may determine whether or not to perform the notification related to the notification step St7 based on the result of the review by the review means 15f. In this embodiment, before the notification step St7, in a decision step St6.5 shown in FIG. 6, it is decided whether or not to perform the notification related to the notification step St7. Specifically, for example, the first cell corresponding to the first cell image B1 of ID: 007 shown in FIG. 3 has a lower value of the electric storage capacity than the first cells corresponding to the other first cell images B1. At this time, when the difference between the electric storage capacity of the first cell corresponding to the first cell image B1 of ID: 007 shown in FIG. 3 and the electric storage capacity of the first cell corresponding to the other first cell images B1 exceeds a predetermined threshold value set arbitrarily (St6.5: YES), the notification step St7 is performed. That is, a message for encouraging the replacement of the cell of ID: 007 is displayed. Specifically, for example, the area corresponding to the cell of ID: 007 on the display unit 13 may be blinked or displayed in a color different from other areas. This may allow the user to quickly replace the cell. When the difference does not exceed a predetermined threshold value set arbitrarily (St6.5: NO), the notification step St7 is not performed.

[0069] The first display control step St8 is a step in which the display control means 15g causes the display unit 13 to display first cell future degree information, which is information on the future degrees of the corresponding plurality of first cells included in the first assembled battery. In the first display control step St8, the display control means 15g may cause the display unit 13 to display assembled battery future degree information corresponding to the first assembled battery including the plurality of first cells.

[0070] In the first display control step St8, for example, the display unit 13 displays first cell future level information based on the assembled battery information identified in the identification step St4 (that is, information on a portion of the combination of a plurality of cells). In the first display control step St8, the following process is carried out based on the information stored in the storage unit 14 in the above-mentioned determination step St3. (a) For example, if it is determined in judgment step St3 that future information is to be specified (i.e., if the processing of step St3a1 described above is performed), then in first display control step St8, based on the information stored in memory unit 14, first cell future degree information, which is the corresponding plurality of cell future degree information for each of the plurality of first cells included in the first assembled battery, may be displayed on display unit 13. (b) For example, if it is determined in judgment step St3 that current information is to be specified, then in first display control step St8, first cell current condition information, which is current condition information of the corresponding multiple first cells included in the first battery pack, may be displayed on the display unit 13 based on the information stored in the memory unit 14.

[0071] The second display control step St9 is a step in which the display control means 15g causes the display unit 13 to display second cell future degree information, which is information on the future degrees of the corresponding plurality of second cells included in the second assembled battery. In the second display control step St9, the display control means 15g may cause the display unit 13 to display assembled battery future degree information corresponding to the second assembled battery including the plurality of second cells.

[0072] In the second display control step St9, for example, the display unit 13 displays information on the future condition of the second cell based on the assembled battery information identified in the identification step St4. In the second display control step St9, the following processing is carried out based on the information stored in the storage unit 14 in the above-mentioned determination step St3. (c) For example, if it is determined in judgment step St3 that future information is to be specified (i.e., if the processing of the above-mentioned step St3b1 is performed), then in second display control step St9, second cell future degree information, which is corresponding cell future degree information for each of the plurality of second cells included in the second assembled battery, may be displayed on the display unit 13 based on the information stored in the memory unit 14. (d) For example, if it is determined in judgment step St3 that current information is to be specified, then in second display control step St9, second cell current condition information, which is current condition information of the corresponding multiple second cells included in the second assembled battery, may be displayed on the display unit 13 based on the information stored in the memory unit 14. The above controls (a) to (d) may be performed in any order.

[0073] In this embodiment, as shown in Figures 3 and 4, the first cell future degree information displayed in the first display control step St8 and the second cell future degree information displayed in the second display control step St9 are displayed on the display unit 13 in a comparable manner. More specifically, in this embodiment, the first cell future degree information and the second cell future degree information may be displayed together on one screen.

[0074] The third display control step St10 is a step in which the display control means 15g causes the display unit 13 to display information on the future state of one of the second cells that needs to be included in the second assembled battery. More specifically, for example, in the case where the combination of the cells of the first assembled battery is specified in advance in the specifying step St4, the display unit 13 displays the cell future condition information of one of the second cells that needs to be included in the second assembled battery to make the performance of the second assembled battery exceed that of the first assembled battery. The second cell that needs to be included in the second assembled battery is, for example, a cell that, if the second cell is removed from the second assembled battery, would not be able to ensure substantially the same performance of the second assembled battery as the first assembled battery. Such a second cell is determined, for example, by the examining means 15f. The display in the third display control step St10 may be, for example, highlighting the second cell image B2 corresponding to the second cell among the multiple second cell images B2. Also, the display unit 13 may display a new window in a blank portion of the second assembled battery image AB2, and display the ID of the target cell in the window. The display control means 15g may output the information to be displayed in the third display control step St10 based on, for example, the result of the examination by the examination means 15f.

[0075] The superimposed display control step St11 is a step of superimposing the battery pack future level information and the battery pack current level information corresponding to the first battery pack and the battery pack future level information and the battery pack current level information corresponding to the second battery pack on a coordinate system AX having one axis corresponding to the battery pack future level information and the other axis corresponding to the battery pack current level information. For example, as shown in Figures 3 to 5, two points indicating the battery pack future level information and battery pack current level information corresponding to the first battery pack, and the battery pack future level information and battery pack current level information corresponding to the second battery pack, are superimposed on the coordinate system AX. In the example shown in Figures 3 to 5, both the future level information and the current level information indicate that the second battery pack has higher performance than the first battery pack. The display control method according to this embodiment is carried out by the above steps. Note that in this embodiment, the above steps may be repeated. Specifically, after the superimposed display control step St11 is completed, the flow may be executed so as to move to the input step St1 again. In this case, for example, various information stored in the storage unit 14 in step St3a1 or step St3b1 in the above-mentioned determination step St3 may be deleted before moving to the input step St1.

[0076] As described above, according to the display control method of this embodiment, in the first display control step St8, the display unit 13 is caused to display the first cell future level information. In the second display control step St9, the display unit 13 is caused to display the second cell future level information. The first cells and the second cells are common, and the arrangement of the first cells in the first assembled battery is different from the arrangement of the second cells in the second assembled battery. In other words, the first assembled battery and the second assembled battery have different combinations of common cells. This allows the user to understand the difference in performance of the assembled batteries caused by the difference in the combination of the cells. This makes it easier for the user to consider a combination of cells that matches the performance required for the assembled battery. Furthermore, by further displaying the first cell future degree information and the second cell future degree information in addition to the battery pack future degree information corresponding to the first battery pack and the second battery pack, the manner in which information is output to the display unit 13 can be improved compared to the case in which only the battery pack future degree information is displayed.

[0077] Furthermore, the plurality of first cell future degree information and the plurality of second cell future degree information are displayed on the display unit 13 in a comparable manner. This allows the user to easily compare the first cell future degree information corresponding to each of the plurality of first cells and the second cell future degree information corresponding to each of the plurality of second cells. Therefore, for example, the user can easily select, from the first assembled battery and the second assembled battery, a battery assembly that includes fewer cells that need to be replaced among the cells included in the assembled battery that the user owns.

[0078] Furthermore, in a first display control step St8, the first cell current condition information is displayed on the display unit 13. In a second display control step St9, the second cell current condition information is displayed on the display unit 13. This allows the user to grasp not only the first cell future condition information but also the first cell current condition information for each of the multiple first cells. Furthermore, the user can grasp not only the second cell future condition information but also the second cell current condition information for each of the multiple second cells. The current condition information of the plurality of cells indicates the current storage capacity, current deterioration level, current maximum output, or current remaining capacity of the cells, so that, for example, the user can appropriately select from the first assembled battery and the second assembled battery a cell included in the assembled battery that the user owns that has a desired current storage capacity, current deterioration level, or current remaining capacity.

[0079] Furthermore, in input step St1, predetermined period information indicating a predetermined period is input. The future time corresponding to the degree indicated by the first cell future degree information and the future time corresponding to the degree indicated by the second cell future degree information correspond to the time after the predetermined period indicated by the predetermined period information input in input step St1. This allows, for example, a user to input desired predetermined period information to ascertain the first cell future degree information and the second cell future degree information after the desired predetermined period has elapsed.

[0080] Furthermore, at least one of the plurality of second cell future level information is determined based on at least one of the battery assembly future level information corresponding to the first battery assembly and the first cell future level information. This makes it possible to more reliably determine the cell future level information of at least one of the plurality of second cells included in the second battery assembly such that the battery assembly future level information corresponding to the first battery assembly and the battery assembly future level information corresponding to the second battery assembly are substantially equal to each other.

[0081] In addition, in the designation step St2, future information indicating the future or present information indicating the present is designated. In the determination step St3, it is determined whether the designation step St2 designates future information or present information. Then, the method includes a first display control step St8 and a second display control step St9. In the first display control step St8, if it is determined in the determination step St3 that the future information is to be specified, the first battery future condition information is displayed on the display unit 13. If it is determined in the determination step St3 that the present information is to be specified, the first battery current condition information is displayed on the display unit 13. In the second display control step St9, if it is determined in the determination step St3 that the future information is to be specified, the second battery future condition information is displayed on the display unit 13. If it is determined in the determination step St3 that the present information is to be specified, the second battery current condition information is displayed on the display unit 13. Thereby, for example, the user can ascertain desired information out of the cell future degree information and the cell current degree information by specifying either the future information or the current information in the specification step St2. Therefore, for example, the user can more easily ascertain desired information out of the cell future degree information and the cell current degree information, compared to a case in which both the first cell future degree information and the first cell current degree information are displayed for each of a plurality of first cells included in the first assembled battery, and both the second cell future degree information and the second cell current degree information are displayed for each of a plurality of second cells included in the second assembled battery.

[0082] In addition, in a notification step St7, a message for encouraging replacement of one of the plurality of first cells is notified to the user. The message is notified to the user when a difference between the degree indicated by the first cell future degree information corresponding to one of the plurality of first cells and the degree indicated by the first cell future degree information corresponding to another one of the plurality of first cells is equal to or greater than a predetermined threshold. This allows the user to easily notice, for example, the possibility that the degree of compatibility with the first assembled battery becomes rate-determining due to a large difference between the degree of compatibility with one of the multiple first cells included in the first assembled battery and the degree of compatibility with a different one of the multiple first cells. This makes it easier to prevent the degree of compatibility with the first assembled battery from becoming rate-determining. According to the above aspect, for example, by detecting a single cell from a group of a plurality of single cells that has a comparatively larger difference in performance than the other single cells, it is possible to easily use a plurality of single cells having different performance from each other as a single assembled battery.

[0083] Furthermore, in the notification step St6, if the level indicated by the battery pack future level information corresponding to the first battery pack is not equal to or greater than the predetermined threshold input by the user, a message is notified to the user to prompt the user to re-input the predetermined threshold. This allows the user to easily re-input the predetermined threshold if, for example, the battery pack future level information corresponding to the first battery pack does not become equal to or greater than the desired predetermined threshold. This makes it easier for the user to efficiently consider the predetermined threshold for the level of the battery pack.

[0084] In addition, in the superimposed display control step St11, the battery assembly future level information and the battery assembly current level information corresponding to the first battery assembly and the battery assembly future level information and the battery assembly current level information corresponding to the second battery assembly are superimposed on a coordinate system AX in which one axis corresponds to the battery assembly future level information and the other axis corresponds to the battery assembly current level information. This allows the user to easily select the desired battery from among the first and second assembled batteries, for example, when the future assembled battery level information and current assembled battery level information of the first assembled battery and the future assembled battery level information and current assembled battery level information of the second assembled battery are Pareto optimal.

[0085] Also, the difference between the level indicated by the battery pack current level information corresponding to the first battery pack and the level indicated by the battery pack future level information corresponding to the first battery pack is equal to or less than a predetermined threshold. This allows, for example, the user to know the first battery pack in which the level indicated by the battery pack future level information is unlikely to decrease from the level indicated by the battery pack current level information from the present to the future. Therefore, the user can know, for example, a combination of batteries that will have a higher workload from the present to the future.

[0086] Furthermore, in the identification step St4, battery pack information indicating a battery pack including a plurality of cells is identified. Then, in the first display control step St8, first cell future extent information based on the battery pack information identified in the identification step St4 is displayed on the display unit 13. This allows, for example, the user to grasp the cell future extent information of each of the plurality of first cells included in the identified battery pack, which have been replaced less frequently. Therefore, for example, the number of cells to be procured from the market can be reduced.

[0087] In addition, in a first display control step St8, the display unit 13 is caused to display assembled battery future level information corresponding to the first assembled battery including the plurality of first cells. In a second display control step St9, the display unit 13 is caused to display assembled battery future level information corresponding to the second assembled battery including the plurality of second cells. The plurality of first cells and the plurality of second cells are common, and the arrangement of the plurality of first cells in the first assembled battery is different from the arrangement of the plurality of second cells in the second assembled battery. In other words, the first assembled battery and the second assembled battery have different combinations of common cells. This allows the user to understand the difference in performance of the plurality of assembled batteries caused by the difference in the combination of the plurality of cells. This makes it easier for the user to consider a combination of cells that matches the performance required of the assembled battery.

[0088] Furthermore, in a third display control step St10, the unit 13 is caused to display unit future degree information of one of the plurality of second cells that need to be included in the second assembled battery. This allows the user to grasp the unit future degree information of the second cell that needs to be included in the second assembled battery in order to make the degree indicated by the first assembled battery future degree information and the degree indicated by the second assembled battery future degree information approximately equal.

[0089] The technical scope of the present disclosure is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present disclosure. For example, the battery pack future level information corresponding to the first battery pack and the battery pack future level information corresponding to the second battery pack do not have to be substantially equal to each other. Furthermore, each of the above-mentioned degree information may include any other information in addition to the degree of the storage capacity, the deterioration degree, the maximum output, or the remaining capacity. Furthermore, the first cell future degree information and the second cell future degree information displayed in the second display control step St9 do not have to be displayed on the display unit 13 so as to be comparable. In addition to the above-mentioned information, any other information may be input in the input step St1. Moreover, the display of the first assembled battery image AB1 and the second assembled battery image AB2 on the display unit 13 may simply be referred to as the first assembled battery and the second assembled battery being displayed on the display unit 13. Moreover, the display of the first cell image B1 and the second cell image B2 on the display unit 13 may simply be referred to as the first cell and the second cell being displayed on the display unit 13. Furthermore, a plurality of combinations of cells in the battery pack may be presented by the review means 15f of the terminal device 10. The plurality of combinations presented in this manner may be displayed on the display unit 13 as options selectable by the user. At this time, the user may be able to determine which option to select by setting a plurality of predetermined periods while grasping the progress of battery deterioration. Furthermore, in addition to the first assembled battery image AB1 and the second assembled battery image AB2, the display unit 13 may further display a third assembled battery image and a fourth assembled battery image having different arrangements of the single cells, or may display even more assembled battery images.

[0090] In addition, within the scope of the present disclosure, the components in the above-described embodiments may be replaced with well-known components as appropriate, and the above-described modified examples may be combined as appropriate.

[0091] (Additional Note) The display control method according to the embodiment can be understood, for example, as follows.

[0092] <1> A display control method according to one embodiment of the present disclosure includes a first display control step of causing a display unit to display, for each of a plurality of first cells included in a first assembled battery, first cell future degree information, which is information about the corresponding cell future degree, and a second display control step of causing the display unit to display, for each of a plurality of second cells included in a second assembled battery, second cell future degree information, which is information about the corresponding cell future degree, wherein the plurality of first cells and the plurality of second cells are common, an arrangement of the plurality of first cells in the first assembled battery is different from an arrangement of the plurality of second cells in the second assembled battery, and the cell future degree information indicates a degree of future storage capacity, future degree of deterioration, future maximum output, or future remaining capacity of a cell.

[0093] According to the above display control method, in the first display control step, the display unit is caused to display information on the future level of the first cell. In the second display control step, the display unit is caused to display information on the future level of the second cell. The first cells and the second cells are common to each other, and the arrangement of the first cells in the first assembled battery is different from the arrangement of the second cells in the second assembled battery. In other words, the first assembled battery and the second assembled battery have different combinations of common cells. This allows the user to understand the difference in performance of the assembled batteries that occurs due to the difference in the combination of the cells. This makes it easier for the user to consider a combination of cells that matches the performance required of the assembled battery. Furthermore, by further displaying the first cell future degree information and the second cell future degree information in addition to the battery pack future degree information corresponding to the first battery pack and the second battery pack, the manner in which information is output to the display unit can be improved compared to when only the battery pack future degree information is displayed.

[0094] <2> the above <1> In the display control method according to the present invention, a configuration may be adopted in which the plurality of pieces of future degree information of the first single battery cells displayed in the first display control step and the plurality of pieces of future degree information of the second single battery cells displayed in the second display control step are displayed on the display unit in a comparable manner.

[0095] Furthermore, the plurality of first cell future degree information and the plurality of second cell future degree information are displayed on the display unit in a comparable manner. This allows the user to easily compare the first cell future degree information corresponding to each of the plurality of first cells and the second cell future degree information corresponding to each of the plurality of second cells. Therefore, for example, the user can easily select, from the first assembled battery and the second assembled battery, a battery assembly that includes fewer cells that need to be replaced among the cells included in the assembled battery that the user owns.

[0096] <3> the above <1> or <2> In the display control method according to the above, a configuration may be adopted in which, in the first display control step, first cell current condition information, which is corresponding cell current condition information for each of the plurality of first cells included in the first assembled battery, is displayed on the display unit, and in the second display control step, second cell current condition information, which is corresponding cell current condition information for each of the plurality of second cells included in the second assembled battery, is displayed on the display unit, and the cell current condition information indicates the current storage capacity, current degree of degradation, current maximum output, or current remaining capacity of a cell.

[0097] Furthermore, in the first display control step, the first cell current condition information is displayed on the display unit. In the second display control step, the second cell current condition information is displayed on the display unit. This allows the user to grasp not only the first cell future condition information but also the first cell current condition information for each of the multiple first cells. Furthermore, the user can grasp not only the second cell future condition information but also the second cell current condition information for each of the multiple second cells. The current condition information of the plurality of cells indicates the current storage capacity, current deterioration level, current maximum output, or current remaining capacity of the cells, so that, for example, the user can appropriately select from the first assembled battery and the second assembled battery a cell included in the assembled battery that the user owns that has a desired current storage capacity, current deterioration level, or current remaining capacity.

[0098] <4> the above <1> from <3> In a display control method according to any one of the above embodiments, a configuration may be adopted in which a predetermined period information indicating a predetermined period is further included in an input step in which predetermined period information indicating a predetermined period is input, and a future time corresponding to the degree indicated by the first cell future degree information and a future time corresponding to the degree indicated by the second cell future degree information correspond to a time after the predetermined period indicated by the predetermined period information input in the input step has elapsed.

[0099] Furthermore, in the input step, predetermined period information indicating a predetermined period is input. The future time corresponding to the degree indicated by the first cell future degree information and the future time corresponding to the degree indicated by the second cell future degree information correspond to the time after the predetermined period indicated by the predetermined period information input in the input step. This allows, for example, a user to know the first cell future degree information and the second cell future degree information after the desired predetermined period has elapsed by inputting desired predetermined period information.

[0100] <5> the above <1> from <4> In the display control method according to any one of the above embodiments, at least one of the plurality of second cell future condition information is determined based on one of battery pack future condition information corresponding to the first battery pack and at least one of the first cell future condition information, and the battery pack future condition information indicates the battery pack's future storage capacity, future degree of deterioration, future maximum output, or future remaining capacity.

[0101] Furthermore, at least one of the plurality of second cell future level information is determined based on at least one of the battery assembly future level information corresponding to the first battery assembly and the first cell future level information. This makes it possible to more reliably determine the cell future level information of at least one of the plurality of second cells included in the second battery assembly such that the battery assembly future level information corresponding to the first battery assembly and the battery assembly future level information corresponding to the second battery assembly are substantially equal to each other.

[0102] <6> A display control method according to one aspect of the present disclosure includes a designation step of designating future information indicating the future or current information indicating the present, a determination step of determining whether the designation step designates the future information or the current information, a first display control step, and a second display control step, In the first display control step, (a) when it is determined that the future information is to be designated in the determining step, displaying, on a display unit, first cell future degree information which is corresponding cell future degree information for each of a plurality of first cells included in the first assembled battery; (b) when it is determined that the current information is to be designated in the determining step, displaying first cell current condition information, which is corresponding cell current condition information for each of a plurality of first cells included in the first assembled battery, on the display unit; In the second display control step, (c) when it is determined that the future information is to be designated in the determining step, displaying second cell future degree information, which is the corresponding cell future degree information, for each of a plurality of second cells included in the second assembled battery on the display unit; (d) when it is determined in the determining step that the current information is to be designated, displaying, on the display unit, second cell current condition information which is the corresponding cell current condition information for each of a plurality of second cells included in the second assembled battery; The single cell future condition information indicates the future storage capacity, future degree of deterioration, future maximum output, or future remaining capacity of the single cell, and the single cell current condition information indicates the current storage capacity, current degree of deterioration, current maximum output, or current remaining capacity of the single cell.

[0103] According to the above display control method, in the designation step, future information indicating the future or present information indicating the present is designated. In the determination step, it is determined whether the designation step designates future information or present information. Then, the display control method includes a first display control step and a second display control step. In the first display control step, if it is determined in the determining step that the future information is to be specified, the display unit displays the first cell future condition information, and if it is determined in the determining step that the present information is to be specified, the display unit displays the first cell present condition information. In the second display control step, if it is determined in the determining step that the future information is to be specified, the second battery future condition information is displayed on the display unit, and if it is determined in the determining step that the present information is to be specified, the second battery current condition information is displayed on the display unit. Thereby, for example, the user can ascertain desired information out of the cell future degree information and the cell current degree information by specifying either the future information or the current information in the specifying step. Therefore, for example, the user can more easily ascertain desired information out of the cell future degree information and the cell current degree information, compared to a case in which both the first cell future degree information and the first cell current degree information are displayed for each of a plurality of first cells included in the first assembled battery, and both the second cell future degree information and the second cell current degree information are displayed for each of a plurality of second cells included in the second assembled battery.

[0104] <7> the above <1> from <6> In the display control method according to any one of the above embodiments, a configuration may be adopted that further includes a notification step of notifying a user of a message encouraging replacement of one of the plurality of first cells when a difference between a degree indicated by the first cell future degree information corresponding to one of the plurality of first cells and a degree indicated by the first cell future degree information corresponding to a different one of the plurality of first cells is equal to or greater than a predetermined threshold.

[0105] In the notification step, a message for prompting replacement of one of the first cells is notified to the user when a difference between the degree indicated by the first cell future degree information corresponding to one of the first cells and the degree indicated by the first cell future degree information corresponding to another one of the first cells is equal to or greater than a predetermined threshold. This allows the user to easily notice, for example, the possibility that the degree of compatibility with the first assembled battery becomes rate-determining due to a large difference between the degree of compatibility with one of the multiple first cells included in the first assembled battery and the degree of compatibility with a different one of the multiple first cells. This makes it easier to prevent the degree of compatibility with the first assembled battery from becoming rate-determining. According to the above aspect, for example, by detecting a single cell from a group of a plurality of single cells that has a comparatively larger difference in performance than the other single cells, it is possible to easily use a plurality of single cells having different performance from each other as a single assembled battery.

[0106] <8> the above <1> from <5> In the display control method according to any one of the above aspects, a configuration may be adopted in which, if the degree indicated by the battery pack future degree information corresponding to the first battery pack is not equal to or greater than a predetermined threshold value input by the user, a notification step is performed of notifying a user of a message for urging the user to re-input the predetermined threshold value, and the battery pack future degree information indicates the future storage capacity, future degree of deterioration, future maximum output, or future remaining capacity of the battery pack.

[0107] In addition, in the notification step, if the level indicated by the battery pack future level information corresponding to the first battery pack is not equal to or greater than the predetermined threshold input by the user, a message is notified to the user to prompt the user to re-input the predetermined threshold. This allows the user to easily re-input the predetermined threshold if, for example, the battery pack future level information corresponding to the first battery pack does not become equal to or greater than the desired predetermined threshold. This makes it easier for the user to efficiently consider the predetermined threshold for the level of the battery pack.

[0108] <9> the above <1> from <5> , and <8> The display control method according to any one of the above aspects may further include an overlay display control step of overlaying the battery pack future level information and the battery pack current level information corresponding to the first battery pack and the battery pack future level information and the battery pack current level information corresponding to the second battery pack on a coordinate system having one axis corresponding to battery pack future level information and the other axis corresponding to battery pack current level information, wherein the battery pack future level information indicates the battery pack's future storage capacity, future degree of deterioration, future maximum output, or future remaining capacity, and the battery pack current level information indicates the battery pack's current storage capacity, current degree of deterioration, current maximum output, or current remaining capacity.

[0109] In the superimposed display control step, the battery assembled future level information and the battery assembled current level information corresponding to the first battery assembled future level information and the battery assembled current level information corresponding to the second battery assembled future level information and the battery assembled current level information corresponding to the second battery assembled future level information and the battery assembled current level information are displayed in a superimposed manner on a coordinate system in which one axis corresponds to the battery assembled future level information and the other axis corresponds to the battery assembled current level information. This allows the user to easily select the desired battery from among the first and second assembled batteries, for example, when the future assembled battery level information and current assembled battery level information of the first assembled battery and the future assembled battery level information and current assembled battery level information of the second assembled battery are Pareto optimal.

[0110] <10> the above <1> from <5> , and <8> , <9> In the display control method according to any one of the above aspects, a configuration may be adopted in which a difference between a degree indicated by current battery pack condition information corresponding to the first battery pack and a degree indicated by future battery pack condition information corresponding to the first battery pack is equal to or less than a predetermined threshold, the future battery pack condition information indicates a future storage capacity, a future degree of deterioration, a future maximum output, or a future remaining capacity of the battery pack, and the current battery pack condition information indicates a current storage capacity, a current degree of deterioration, a current maximum output, or a current remaining capacity of the battery pack.

[0111] Also, the difference between the level indicated by the battery pack current level information corresponding to the first battery pack and the level indicated by the battery pack future level information corresponding to the first battery pack is equal to or less than a predetermined threshold. This allows, for example, the user to know the first battery pack in which the level indicated by the battery pack future level information is unlikely to decrease from the level indicated by the battery pack current level information from the present to the future. Therefore, the user can know, for example, a combination of batteries that will have a higher workload from the present to the future.

[0112] <11> the above <1> from <10> In the display control method according to any one of the above aspects, a configuration may be adopted in which a determination step is performed in which assembled battery information indicating an assembled battery including a plurality of cells is determined, and in the first display control step, information on the future extent of the first cell based on the assembled battery information determined in the determination step is displayed on the display unit.

[0113] In the identifying step, battery pack information indicating a battery pack including a plurality of cells is identified. Then, in the first display control step, first cell future extent information based on the battery pack information identified in the identifying step is displayed on the display unit. This allows, for example, a user to know the cell future extent information of each of the plurality of first cells included in the identified battery pack, which have been replaced less frequently. This makes it possible, for example, to reduce the number of cells procured from the market.

[0114] <12> A display control method according to one embodiment of the present disclosure includes a first display control step of causing a display unit to display battery assembly future level information corresponding to a first assembled battery including a plurality of first cells, and a second display control step of causing the display unit to display the battery assembly future level information corresponding to a second assembled battery including a plurality of second cells, wherein the battery assembly future level information indicates the battery assembly's future storage capacity, future degree of deterioration, future maximum output, or future remaining capacity, and the plurality of first cells and the plurality of second cells are common, and an arrangement of the plurality of first cells in the first assembled battery is different from an arrangement of the plurality of second cells in the second assembled battery.

In the second display control step, battery pack future level information corresponding to a second assembled battery including a plurality of second cells is displayed on the display unit. The plurality of first cells and the plurality of second cells are common, and the arrangement of the plurality of first cells in the first assembled battery is different from the arrangement of the plurality of second cells in the second assembled battery. In other words, the first assembled battery and the second assembled battery have different combinations of common cells. This allows the user to understand the difference in performance of the plurality of assembled batteries caused by the difference in the combination of the plurality of cells. This makes it easier for the user to consider a combination of cells that matches the performance required of the assembled battery.

[0116] <13> the above <1> from <12> In the display control method according to any one of the above embodiments, a third display control step of causing the display unit to display future cell condition information of one of the plurality of second cells that needs to be included in the second battery pack may be adopted, wherein the future cell condition information indicates the future storage capacity, future degree of deterioration, future maximum output, or future remaining capacity of the cell.

[0117] In the third display control step, the display unit displays the unit cell future degree information of one of the second cells that needs to be included in the second assembled battery, allowing the user to grasp the unit cell future degree information of the second cell that needs to be included in the second assembled battery in order to make the degree indicated by the first assembled battery future degree information and the degree indicated by the second assembled battery future degree information approximately equal.
