Summary of the Invention

Problems to be Solved by the Invention

[0006] However, Patent Document 1 does not specifically disclose a relocation schedule that is displayed on a screen or printed out. Furthermore, Patent Document 2 does not specifically disclose a delivery slip.

[0007] This disclosure is made in view of these problems and aims to provide a technology that allows users to easily obtain information regarding the relocation of storage batteries. [Means for solving the problem]

[0008] The display control method of this disclosure includes a display control step of displaying on a display unit a combination of first battery identification information that identifies the first battery and relocation location information that indicates the location of the relocation destination of the first battery, which is the location of the consumer who will use the first battery. The display control device of this disclosure includes a display control means that causes a display unit to display, in association with, first battery identification information that identifies a first battery and relocation location information that indicates the location of the relocation destination of the first battery, which is the location of a consumer who will use the first battery. [Effects of the Invention]

[0009] This disclosure provides a technology that allows users to easily obtain information regarding the relocation of storage batteries. [Brief explanation of the drawing]

[0010] [Figure 1] This is an example of a battery transfer flow. [Figure 2A] This is a block diagram showing the configuration of the display control device of this embodiment. [Figure 2B] This is a block diagram showing the configuration of the control unit of this embodiment. [Figure 3] This is an example of a normal screen displayed on the display unit of this embodiment. [Figure 4] This is an example of a screen displayed on the display unit of this embodiment after selection. [Modes for carrying out the invention]

[0011] It is common practice to relocate and use storage batteries, for example, depending on their degree of degradation. This disclosure relates to a display control method, a display control device 1, and a display control program, which can be used in a business model in which, for example, a grade evaluation is performed on multiple storage batteries to evaluate their degree of degradation (performance), and each storage battery is transported to a customer's location who desires a storage battery with a specific evaluation, according to the evaluation corresponding to the performance of each storage battery, and this process is repeated. In such a business model, by appropriately matching storage batteries with customers, even if the performance of a storage battery deteriorates, its use can be continued by relocating it to a suitable customer. Storage batteries may degrade depending on their operating time. Therefore, the grade evaluation may be performed, for example, based on the operating history information of the storage battery. Alternatively, the grade evaluation may be performed, for example, by the person performing the grade evaluation measuring the performance of the installed storage battery. For example, the degradation state of a used storage battery can be derived by actual measurement. For example, by charging a battery until it reaches a state where it will not overcharge (charge termination voltage) and then discharging it until it reaches a state where it will not over-discharge (discharge termination voltage), and measuring the discharged current, the current storage capacity (i.e., the degraded storage capacity) of a used battery can be derived. In this case, the degradation state of a used battery can be determined accurately and reliably.

[0012] Figure 1 shows an example of the battery transfer flow. In the example in Figure 1, the battery is graded before transfer. The following describes a case where grades A, B, C, and D are assigned in descending order of performance during the grade evaluation. The evaluation method is not limited, and the evaluation stages are not limited to the four stages from A to D.

[0013] Batteries assigned a grade through the grading process are relocated to the locations of customers who wish to use batteries with that grade. Batteries assigned a grade through the grading process may also be recycled according to their grade. In the example in Figure 1, a battery with grade A is installed and used at location A of customer A who wishes to use a battery with grade A; a battery with grade B is installed and used at location B of customer B who wishes to use a battery with grade B; a battery with grade C is installed and used at location C of customer C who wishes to use a battery with grade C; and a battery with grade D is recycled. Note that batteries assigned a grade through the grading process do not necessarily have to be relocated (details will be provided later).

[0014] For example, if the installation period or cycle count of a battery at a customer's location exceeds a certain level, the battery's grade evaluation is re-evaluated. After the grade evaluation is re-evaluated and a new grade is assigned, the battery is transferred to the location of a customer who wishes to use a battery with that grade, according to the new evaluation.

[0015] Specifically, the transfer of a battery follows a flow such as the following: For example, Battery 1, which received a rating of A in the first grade evaluation, is transferred to location A of customer A as the first transfer destination, where it is installed and used. After a certain period of time has elapsed since Battery 1 was installed at location A, Battery 1 undergoes a second grade evaluation.

[0016] For example, in the second grade evaluation, if the first storage battery is given evaluation A, which is the same as the first evaluation, the first storage battery may not be transferred and the use at consumer A may continue. From the perspective of optimally using all storage batteries in operation, storage batteries with a grade evaluation at a predetermined level may be transferred to the location of a consumer who wishes to use a storage battery with an evaluation below that predetermined level. Specifically, the storage battery given evaluation A may be transferred to location B of consumer B or location C of consumer C. For example, in the second grade evaluation, if a different evaluation than the first evaluation is given to the first storage battery, the first storage battery is transferred to the location of a consumer who wishes to use a storage battery with each evaluation according to the new evaluation. For example, in the second grade evaluation, if evaluation B is given to the first storage battery, the first storage battery may be transferred to location B of consumer B as the second transfer destination location and installed and used. From the perspective of optimally using all storage batteries in operation, the storage battery given evaluation B may also be transferred to location C of consumer C. For example, in the second grade evaluation, if evaluation C is given to the first storage battery, the first storage battery may be transferred to location C of consumer C as the second transfer destination location and installed and used. For example, in the second grade evaluation, if evaluation D is given to the first storage battery, the first storage battery is recycled.

[0017] In the example of FIG. 1, except when evaluation D is given to the first storage battery and the first storage battery is recycled, the above flow is repeatedly implemented for the first storage battery.

[0018] In the above business model, the grade evaluation of the storage battery is implemented at regular intervals and transferred to an appropriate consumer location, so that the consumer can continue to use a storage battery with the required evaluation and the storage battery can be used, for example, over a long period.

[0019] Hereinafter, embodiments of the display control device 1, the display control method, and the display control program according to the present disclosure will be described while referring to the drawings.

[0020] (Display control device 1) The display control device 1 of the present disclosure associates the first battery identification information 110 for identifying the first battery with the transfer destination location information 130 indicating the location of the transfer destination of the first battery, which is the location of the customer who uses the first battery, and causes the display unit D to display them. The battery is preferably, for example, an all-solid-state battery, a lithium-ion battery, a lead-acid battery, etc. Note that the batteries described hereinafter include battery cells, battery modules, and battery packs. In the description of the display control device 1, each component included in the display control device 1 will be described.

[0021] FIG. 2A is a block diagram of the display control device 1 in the present embodiment. The display control device 1 includes a control unit 30 including a processor P such as a CPU (Central Processing Unit) connected by a bus and a memory M, and executes a display control program. The display control program is, for example, a program for controlling the display of the display unit D of the display control device 1. The display control device 1 functions as a device including a user interface 10, a storage unit 20, and a control unit 30 by executing the display control program. The display control program according to the present embodiment is a program that causes a computer to function as the display control device 1 according to the present embodiment.

[0022] More specifically, the display control device 1 reads out the display control program stored in the storage unit 20 by the processor P, and stores the read display control program in the memory M. By the processor P executing the display control program stored in the memory M, the display control device 1 functions as a device including a user interface 10, a storage unit 20, and a control unit 30.

[0023] The user interface 10 includes a display unit D and an input unit I. The display unit D displays various information. The display unit D includes, for example, an output device such as a CRT (Cathode Ray Tube) display, a liquid crystal display, an organic EL (Electro-Luminescence) display, etc. The display unit D may be configured as an interface for connecting these output devices to the control device.

[0024] Input Unit I comprises input terminals such as a mouse, keyboard, or touch panel. Input Unit I may also be configured as an interface for connecting these input terminals to the display control device 1. Input Unit I accepts various types of information for input to the display control device 1 (details will be described later). The display unit D and the input unit I may be configured as a single touch panel.

[0025] The storage unit 20 is configured using a non-temporarily computer-readable storage medium device such as a magnetic hard disk drive or a semiconductor memory device. The storage unit 20 stores various information related to the display control device 1. For example, the storage unit 20 pre-stores a display control program.

[0026] The control unit 30 controls the operation of each functional unit provided by the display control device 1. Figure 2B shows an example of the functional configuration of the control unit 30 according to the embodiment. As shown in Figure 2B, the control unit 30 comprises a receiving unit 31 (input means) and a display control means 32.

[0027] The receiving unit 31 receives information input to, for example, the input unit I. In this embodiment, the receiving unit 31 receives various types of information, which will be described later. For example, the receiving unit 31 acquires information regarding the transfer of the storage battery. Details of the information regarding the transfer of the storage battery will be described later.

[0028] The display control means 32 causes the display unit D to display various information.

[0029] (Display control method) The display control method of this embodiment includes a display control step. In the display control method of this embodiment, the display control means 32 causes the display unit D to display various information in the display control step. The display control method may further include a selection step. In the selection step, the user may select the information displayed in the display control step. At this time, the display control device 1 may accept the selection and update the information.

[0030] Figures 3 and 4 show examples of screens displayed on the display unit D. In the display control step, the screen displayed on the display unit D changes, for example, when the user selects information in the selection step (details will be described later). In the display control step, the screen displayed on the display unit D may also change, for example, when information is updated.

[0031] In the display control step, the display control means 32 causes the display unit D to display, for example, first battery identification information 110 that identifies the first battery and destination location information 130 that indicates the destination location of the first battery, which is the location of the consumer using the first battery, in association with each other. Displaying this information in association means that it is displayed in a form that allows the user to recognize the correspondence between the information. Displaying the information in association may also mean, for example, displaying it on the same row in the table 200 displayed on the display unit D, as shown in the illustrated example. Note that these various types of information (and the information shown below) may be received by the receiving unit 31 or stored in the storage unit 20. The display control means 32 causes the display unit D to display these various types of information as described above.

[0032] Figure 3 shows an example of a screen displayed on display unit D. The following explanation will refer to Figure 3 to describe the screens displayed on display unit D.

[0033] Figure 3 illustrates an example where information regarding the transfer of four batteries—the first, second, third, and fourth batteries—is displayed on the display unit D. However, the number of pieces of information displayed on the display unit D is not limited.

[0034] As shown in Figure 3, in the display control step of this embodiment, the display control means 32 displays the first battery identification information 110 and the relocation destination information 130, along with the installation location information 140, the original relocation location information 120, the worker identification information 150, the spare part identification information 160, the grade information 170, the requested grade information 280, the operating status information 180, the replacement feasibility information 210, the replacement time 220, the power supply status information 190, the charge amount information 230, the size information, the weight information 240, the guide information 250, the transport status information 260, and the location information 270 as the normal screen 100. In the display control step of this embodiment, it is sufficient to display at least the first battery identification information 110 and the relocation destination information 130 in association with the display unit D, and it is not limited to displaying all of the above information on the display unit D.

[0035] In the following description, "user" refers to a person who checks the information displayed on the display unit D by the display control method of this disclosure. The user is not limited to, but may be, for example, a worker engaged in the transportation of storage batteries, or for example, a monitor who remotely monitors the transportation status of storage batteries.

[0036] The battery identification information 110 is information for identifying a battery. The battery identification information 110 may be, for example, an ID assigned to each battery. In this embodiment, each battery is assigned a battery ID consisting of a three-digit number. In this embodiment, the first battery is assigned the ID "111" as the first battery identification information 110, the second battery is assigned the ID "112" as the second battery identification information 110, the third battery is assigned the ID "113" as the third battery identification information 110, and the fourth battery is assigned the ID "114" as the fourth battery identification information 110. The battery identification information 110 is not limited to a battery ID consisting of a three-digit number, and is not limited to information that allows a user to identify a battery.

[0037] The relocation destination information 130 is information indicating the location of the relocation destination, which is the location of the consumer using the battery. Alternatively, as described later, the relocation destination information 130 may be information about a location where relocation is possible. The relocation destination information 130 should be information that allows the user to recognize the location of the relocation destination, which is the location of the consumer using the battery. The relocation destination information 130 may be, for example, an address or coordinates. In this embodiment, "Location A2" is displayed as the first relocation destination information 130 indicating the relocation destination of the first battery, "Location B2" is displayed as the second relocation destination information 130 indicating the relocation destination of the second battery, "Location B4" is displayed as the third relocation destination information 130 indicating the relocation destination of the third battery, and "Location C2" is displayed as the first relocation destination information 130 indicating the relocation destination of the fourth battery. Here, "Location A2", "Location B2", "Location B4", and "Location C2" may be, for example, an address or coordinates. The relocation destination information 130 may be determined, for example, based on the degree of battery degradation (assessment) and candidate relocation destinations (customer location and required assessment).

[0038] The installation location information 140 indicates the installation location where the battery will be installed at the relocation destination indicated by the relocation destination location information 130. For example, if the relocation destination is a large facility such as a factory, there may be multiple locations where the battery can be installed (installation locations). Examples of installation locations for the battery include racks for battery installation. In such cases, simply displaying the address of the large facility may not allow the user to understand the details of the battery's installation location.

[0039] Therefore, unlike the relocation destination information 130, the installation location information 140 indicates the detailed installation location of the battery at the relocation destination. Specifically, for example, if the relocation destination information 130 is the address of a factory facility, the installation location information 140 may be the identification number of the building where the battery will be installed within the factory facility, or the identification number of the rack where the battery will be installed. In this embodiment, the first installation location information 140 indicating the installation location of the first battery is displayed as "rack a1", the second installation location information 140 indicating the installation location of the second battery is displayed as "rack b2", the third installation location information 140 indicating the installation location of the third battery is displayed as "rack b3", and the fourth installation location information 140 indicating the installation location of the fourth battery is displayed as "rack c4". The installation location information 140 may be determined, for example, based on the degree of battery degradation (evaluation), candidate installation locations, and the evaluation required by the customer.

[0040] The source location information 120 indicates the source location of the battery. The source location information 120 should be any information that allows the user to recognize the source location, which is the location of the battery before it was moved. The source location information 120 may be, for example, an address or coordinates. In this embodiment, "Location A1" is displayed as the first source location information 120 indicating the source of the first battery, "Location B1" is displayed as the second source location information 120 indicating the source of the second battery, "Location B3" is displayed as the third source location information 120 indicating the source of the third battery, and "Location C1" is displayed as the first source location information 120 indicating the source of the fourth battery. Here, "Location A1", "Location B1", "Location B3", and "Location C1" may be, for example, an address or coordinates.

[0041] In this embodiment, the battery identification information 110, the destination location information 130, and the source location information 120 are displayed in association with each other. Therefore, by checking these three pieces of information displayed on the screen, the user can understand which battery should be moved from where to where. Specifically, in the screen shown in Figure 3, the user can understand that the first battery should be moved from location A1 to location A2, the second battery from location B1 to location B2, the third battery from location B3 to location B4, and the fourth battery from location C1 to location C2.

[0042] The worker identification information 150 indicates information that identifies the worker who transports the battery to the relocation site. The worker identification information 150 may be, for example, a worker ID assigned to each worker. In this embodiment, workers are assigned a worker ID consisting of a four-digit number. In this embodiment, the worker responsible for transporting the first battery is assigned the ID "1111" as the first worker identification information 150, the worker responsible for transporting the second battery is assigned the ID "1112" as the second worker identification information 150, the worker responsible for transporting the third battery is assigned the ID "1113" as the third worker identification information 150, and the worker responsible for transporting the fourth battery is assigned the ID "1114" as the fourth worker identification information 150. The worker identification information 150 is not limited to a worker ID consisting of a four-digit number, and can be any information that allows a user to identify a worker. The worker identification information 150 may be determined, for example, based on the destination location. The worker identification information 150 may also be determined, for example, based on the distance from the source location to the destination location. When the worker identification information 150 is changed (updated), the screen displayed on the display unit D in the display control step may change. The worker identification information 150 can be changed, for example, in response to user input, and when it is changed in this way, the screen may be updated to reflect the changed content on the screen.

[0043] In this embodiment, the user can understand which worker will transport each battery by checking the worker identification information 150. Specifically, in the screen shown in Figure 3, the user can understand that the first battery will be transported by worker with ID "1111", the second battery by worker with ID "1112", the third battery by worker with ID "1113", and the fourth battery by worker with ID "1114".

[0044] Spare part identification information 160 indicates a spare part for the first battery. This will be explained using the example of replacing the transported first battery with the first battery already installed in rack a1 at the first relocation site. For example, if the first battery, which was initially intended to be replaced with the first battery, becomes unusable for some reason, the 11th single cell may be replaced with the 21st battery, which has equivalent performance (evaluation) to the unusable battery. A spare part (spare battery) refers to a replacement battery used in such a case.

[0045] The spare part identification information 160 may be a battery ID consisting of a three-digit number, similar to the battery identification information 110. In this embodiment, the 21st battery, which is a replacement for the first battery, is assigned the ID "211" as the first spare part identification information 160; the 12th battery, which is a replacement for the second battery, is assigned the ID "212" as the second spare part identification information 160; the 13th battery, which is a replacement for the third battery, is assigned the ID "213" as the third spare part identification information 160; and the 14th battery, which is a replacement for the fourth battery, is assigned the ID "214" as the fourth spare part identification information 160. The battery identification information 110 is not limited to a battery ID consisting of a three-digit number, as long as it is information that allows the user to identify the battery.

[0046] Battery No. 21, which will serve as a spare for Battery No. 1, may be transported together with Battery No. 1, which will be moved. Battery No. 21, which will serve as a spare for Battery No. 1, may be stored in advance at the relocation site of Battery No. 1. In the display control step, if information regarding spare parts is to be displayed on the display unit D, for example, spare part location information may be displayed on the display unit D. The spare part location information indicates the storage location of the 21st battery, which is a spare part for the first battery. By displaying the spare part location information on the display unit D in the display control step, the user can easily find out where the 21st spare battery, which serves as a spare, is stored when the first battery is unavailable. The spare part identification information 160 may be determined, for example, based on the degree of battery degradation (assessment) and the candidate relocation destination (customer's location and required assessment).

[0047] If there are no spare parts for the storage battery (i.e., no spare part identification information), a warning may be displayed on display unit D. Specifically, for example, if there are no spare parts for the first storage battery and the first spare part identification information 160 is not displayed on display unit D, a warning indicating that the first spare part identification information 160 is not available may be displayed on display unit D.

[0048] Grade information 170 indicates the degree of degradation of the battery. Grade information 170 may be, for example, an evaluation assigned to each battery by a grade evaluation. In this embodiment, the evaluation displayed as grade information 170 has four levels, from highest performance to lowest: evaluation A, evaluation B, evaluation C, and evaluation D, with one evaluation assigned to each battery. The evaluation may be a numerical value indicating the degree of degradation. In this embodiment, the first battery is assigned "A" as the first grade information 170, the second battery is assigned "B" as the second grade information 170, the third battery is assigned "B" as the third grade information 170, and the fourth battery is assigned "C" as the fourth grade information 170. In this embodiment, the letters A to C listed in the "Grade" column of the table correspond to evaluations A to C, respectively. That is, in this embodiment, the first battery with evaluation A has the highest performance, and the fourth battery with evaluation C has the lowest performance. In this embodiment, batteries assigned a rating of D are recycled or disposed of and are not transported to the customer's location. Batteries assigned a rating of D are transported, for example, to a processing facility that recycles batteries. When the grade information 170 is changed (updated), the screen displayed on the display unit D in the display control step may change. The grade information 170 can be changed, for example, in response to user input, and when changed in this way, the screen may be updated to reflect the changed content. Also, if the grade evaluation is performed again, the information of the battery that has undergone the grade evaluation again may be highlighted. The method of highlighting is not limited; for example, the information of the battery that has undergone the grade evaluation again may be displayed in bold, or the row containing the information of the battery that has undergone the grade evaluation again may be colored. When the grade evaluation is performed again, the corresponding battery information may be displayed in addition.

[0049] Grade information 170 may include degradation prediction information, which is a prediction of battery degradation. Degradation prediction information may include, for example, information on when a battery currently at "Evaluation A" will change to "Evaluation B," when a battery currently at "Evaluation B" will change to "Evaluation C," and when a battery at "Evaluation C" will change to "Evaluation D." Degradation prediction information may also be information obtained based on the battery's history information, the battery's current degree of degradation, and the usage plan at the installation site. Degradation prediction information may also be data obtained by estimating the future degree of degradation under long-term use from the degree of degradation due to long-term use, by using the battery for a very short period and allowing it to degrade slightly. In this case, the degree of degradation may be predicted by creating a degradation prediction curve from time transition data of the degradation state (SOH) of the battery information in use. Alternatively, the degree of degradation may be predicted by calculating a degradation prediction curve from the history information of the battery in use (for example, voltage log, current log, temperature log data), assuming that similar usage conditions will continue.

[0050] The requested grade information 280 indicates the grade of battery required by each customer corresponding to each of the multiple relocation location information 130 requested by the customer. In this embodiment, the evaluation displayed as the requested grade information 280 corresponds to the evaluation stage displayed as the grade information 170. The customer who uses the battery at the first relocation location is designated as the first customer, the customer who uses the battery at the second relocation location is designated as the second customer, the customer who uses the battery at the third relocation location is designated as the third customer, and the customer who uses the battery at the fourth relocation location is designated as the fourth customer. In this case, Figure 3 shows that the grade of battery requested by the first customer (first requested grade information 280) is evaluation A, the grade of battery requested by the second customer (second requested grade information 280) is evaluation B, the grade of battery requested by the third customer (third requested grade information 280) is evaluation B, and the grade of battery requested by the fourth customer (fourth requested grade information 280) is evaluation C. When the requested grade information 280 is changed (updated), the screen displayed on the display unit D in the display control step may change. The requested grade information 280 can be changed, for example, in response to user input, and when it is changed in this way, the screen may be updated to reflect the changed content on the screen.

[0051] When installing a battery at a relocation site (e.g., a rack), if, for example, a battery already installed in the rack is discharging, it may not be possible to install another battery in the rack. In this embodiment, in the display control step, the display unit D displays information related to whether or not the first battery, which is scheduled to be installed (scheduled to be replaced) in a predetermined location, is in a state where it can be installed in that predetermined location. The following describes the case in which the transported first battery is to be replaced with the first-1 battery already installed in rack a1 at the first relocation site.

[0052] Installation feasibility information includes, for example, at least one of the following: operating status information 180, replacement feasibility information 210, replacement feasibility time 220, and power-on status information 190. Installation feasibility information is obtained, for example, by communicating with the control device at the relocation site (e.g., PLC).

[0053] Operating status information 180 indicates the current operating status of the rack on which the battery is installed. The rack on which the battery is installed may also refer to the rack on which the battery is scheduled to be installed.

[0054] In this embodiment, the operating status information 180 indicates one of the following: standby, charging, or discharging. In the illustrated example, the first operating status information 180 for rack a1, where the first battery is to be installed, is displayed as "standby," the second operating status information 180 for rack b2, where the second battery is to be installed, is displayed as "discharging," the third operating status information 180 for rack b4, where the third battery is to be installed, is displayed as "discharging," and the fourth operating status information 180 for rack c2, where the fourth battery is to be installed, is displayed as "standby."

[0055] The replaceability information 210 indicates whether the first battery is replaceable with the first-1 battery which is scheduled to be replaced by the first battery. The replaceability information 210 may be, for example, replaceable status information or replaceable grade information. In the illustrated example, the replaceability information 210 shows replaceable status information. The replaceability information 210 may also be displayed in association with replaceable status information and replaceable grade information.

[0056] The interchangeability status information indicates whether the first battery is interchangeable with the first battery already installed in the rack where the first battery is to be installed, based on the feasibility of a series of interchangeability processes. Here, the feasibility of a series of interchangeability processes may, for example, indicate whether the time, place, or timing is appropriate for the interchange. In the illustrated example, since rack a1, where the first battery is scheduled to be installed, is in standby mode (not energized), the first replaceable status information (first replaceability information 210) for rack a1, where the first battery is scheduled to be installed, is displayed as "Yes". Since rack b2, where the second battery is scheduled to be installed, is in discharge mode (energized), the second replaceable status information (second replaceability information 210) for rack b2, where the second battery is scheduled to be installed, is displayed as "No". Since rack b4, where the third battery is scheduled to be installed, is in discharge mode (energized), the third replaceable status information (third replaceability information 210) for rack b4, where the third battery is scheduled to be installed, is displayed as "No". Since rack c2, where the fourth battery is scheduled to be installed, is in standby mode (not energized), the fourth replaceable status information (fourth replaceability information 210) for rack c2, where the fourth battery is scheduled to be installed, is displayed as "Yes".

[0057] The interchangeability grade information indicates whether the first battery is interchangeable with the first-1 battery, based on whether the first battery has the necessary evaluation to be installed at the installation site. In the illustrated example, all evaluations of the first to fourth batteries are equivalent to the corresponding customer's required grade information. Therefore, all batteries from the first to fourth batteries are installable at the installation site, and the interchangeability grade information is "Yes". Specifically, "Yes" may be displayed as the first interchangeability grade information for the first battery, "Yes" may be displayed as the second interchangeability grade information for the second battery, "Yes" may be displayed as the third interchangeability grade information for the thirteenth battery which is scheduled to be replaced with the third battery, and "Yes" may be displayed as the fourth interchangeability grade information for the fourteenth battery which is scheduled to be replaced with the fourth battery. For example, if the first battery does not have the necessary evaluation to be installed at the installation site, the first battery cannot be replaced with the first-1 battery. In this case, "No" may be displayed as the first interchangeability grade information. Here, "not having the appropriate rating for installation at the site" means that the battery's rating is lower than the rating required for installation at the site (the customer's required grade). Specifically, for example, if the rating required for installation at the site (the customer's required grade) is rating A, then the rating of the first battery is rating B or lower.

[0058] The power status information 190 indicates whether the 1-1 battery, which will be replaced with the 1st battery, is powered or not. In the illustrated example, the 1st power status information 190 for rack a1, where the 1st battery is scheduled to be installed, is displayed as "Not powered" for rack b2, where the 2nd battery is scheduled to be installed, is displayed as "Powered" for rack b4, where the 3rd battery is scheduled to be installed, and is displayed as "Not powered" for rack c2, where the 4th battery is scheduled to be installed.

[0059] The replaceable time 220 indicates the time at which the first battery becomes replaceable with the first-1 battery, which is scheduled to be replaced by the first battery. In other words, the time indicated by the replaceable time 220 information may be, for example, the time when the operating status information 180 switches from "discharging" to "standby", for example, the time when the replaceability information 210 (replaceable status information) switches from "not" to "possible", for example, the time when the power supply status information 190 switches from "powered" to "not powered".

[0060] Therefore, if the current operating status information 180 is "standby", the replaceability information 210 is "possible", or the power supply status information 190 is "not powered", the replaceable time 220 will be the current time, and therefore the replaceable time 220 does not need to be displayed. As shown in Figure 3, the time may only be displayed as replaceable time 220 information in the "Replaceable Time 220" column if the operating status information 180 is "discharging", the replaceability information 210 is "not possible", or the power supply status information 190 is "powered".

[0061] Furthermore, for example, in the selection step, the installation feasibility status may be switched by having the user select information related to installation feasibility. Here, having the user select means, for example, that the user operates and clicks on the screen displayed on the display unit D via the input unit I, or for example, that the user taps any button on the screen displayed on a touch panel in which the input unit I and the display unit D are integrated. In this embodiment, the installation feasibility status is linked to, for example, the operating status of the rack in which the battery is to be installed. Therefore, by switching the installation feasibility status, for example, the operating status of the rack in which the battery is to be installed can be switched. At this time, for example, the display control device 1 may receive input and change the operating status of the battery as appropriate.

[0062] Specifically, for example, if the operating status information 180 is "discharging," the operating status information 180 can be switched from "discharging" to "standby" by having the user select the text "discharging" in the operating status information 180. Specifically, for example, if the exchangeability information 210 is set to "No", the exchangeability information 210 can be switched from "No" to "Yes" by having the user select the word "No" which is the exchangeability information 210. Specifically, for example, if the power status information 190 is set to "Powered," the power status information 190 can be switched from "Powered" to "Not Powered" by having the user select the text "Powered" which is the power status information 190.

[0063] Furthermore, due to circumstances such as a malfunction in the rack at the installation location, it may not be possible to switch the installation status even if the user is allowed to select information related to installation feasibility. In this case, during the display control step, the display control means 32 may, for example, display an error on the display unit D, or it may display information on the display unit D indicating that other work (work other than selecting information related to installation feasibility), such as repair, is required.

[0064] If a battery is nearly 100% charged, it may discharge during transport or storage. Therefore, it is preferable to transport and store the battery with an appropriate charge level, depending on the length of the transport and storage period. Furthermore, the appropriate charge level for a battery when transporting and storing it will vary depending on the transport time and storage period.

[0065] The charge level information 230 indicates at least one of the charge level of the first battery and the charge level of the first-1 battery that will be replaced with the first battery.

[0066] In the display control step, the display control means 32 may display the transport time in addition to the charge amount information 230. The transport time may indicate at least one of the time required to transport the first battery to the first relocation site, and the time required to transport the 1-1 battery, which has been replaced with the first battery and removed from the installation site, to the next relocation site.

[0067] Size information 240 indicates the size of the battery. Size information 240 is not limited to information that allows the user to recognize the size of the battery. From the perspective that even workers who are not specialists in battery transport can understand the size of the first battery by checking size information 240, it is preferable that the size information 240 of the battery be a specific numerical value indicating the size of the battery. The size information 240 of the battery may also be a symbol or number indicating the specifications of the battery. Weight information 240 indicates the weight of the battery. From the perspective that even workers who are not specialists in battery transport can understand the weight of the first battery by checking weight information 240, it is preferable that the weight information 240 of the battery be a specific numerical value indicating the weight of the battery. The weight information 240 of the battery may also be a symbol or number indicating the specifications of the battery.

[0068] Guide information 250 shows how to replace the battery. The method of replacing the battery may differ depending on the type of battery (model number, etc.). In this embodiment, the selection step allows the user to check the replacement method for the battery in the "Guide" column of the table, in the row corresponding to the battery for which they wish to check the replacement method. choice By selecting the " button, the display control means 32 switches the screen displayed on the display unit D from the normal screen 100 shown in Figure 3 to the post-selection screen 300 shown in Figure 4 during the display control step. In the post-selection screen 300 shown in Figure 4, a speech bubble-shaped pop-up 310 indicating the selected battery is displayed on the display unit D. In this embodiment, the pop-up 310 of the post-selection screen 300 shown in Figure 4 displays guide information 250 indicating how to replace the selected battery. Specifically, in the normal screen 100 shown in Figure 3, the row corresponding to the first battery is " choice By selecting the " button, the first guide information 320 corresponding to the method of replacing the first battery will be displayed in the pop-up 310 of the post-selection screen 300 shown in Figure 4.

[0069] Guide information 250 can be any information that allows the user to understand how to replace the battery, and is not limited to the examples above.

[0070] The users of this disclosure are, for example, those who check the information displayed on the display unit D by the display control device 1 of this disclosure. This includes not only workers who actually transport and install the storage battery, but also, for example, monitors who remotely monitor the transportation and installation of the storage battery. The monitor preferably confirms, for example, the status of the storage battery's transportation, such as when the storage battery has departed from the source, is in transit, or has arrived at the destination. Transportation status information 260 shows the transportation status of the storage battery.

[0071] In Figure 3, the first transport status information 260 indicating the transport status of the first battery is displayed as "in transport," the second transport status information 260 indicating the transport status of the second battery is displayed as "in transport," the third transport status information 260 indicating the transport status of the third battery is displayed as "arrived," and the fourth transport status information 260 indicating the transport status of the fourth battery is displayed as "departed." The transportation status can be any information that allows the user to understand the status of the battery's transportation, and is not limited to being expressed in three stages: "departure," "in transit," and "arrival." For example, the transportation status may also include "waiting" and "storage."

[0072] The supervisor preferably checks location information 270 indicating the location of the battery, for example, as part of the status of the battery's transportation. Location information 270 indicates the location of the battery.

[0073] Location information 270 is not limited to any information that allows the user to know the location information 270 of the battery. Location information 270 may be, for example, coordinates indicating the current location of the battery, for example, an address, or for example, the time when it passed a relay point. In this embodiment, location information 270 is coordinates. In this embodiment, in the selection step, the row in the "Current Location" column corresponding to the battery for which the user wishes to check the current location information 270 is selected (coordinate)You can select the " " button. (coordinate) By selecting the " " button, in the display control step, the screen displayed on the display unit D is switched from the normal screen 100 shown in Figure 3 to the selected screen 300 shown in Figure 4.

[0074] In the post-selection screen 300 shown in Figure 4, a speech bubble-shaped pop-up 310 indicating the selected battery is displayed on the display unit D. From the viewpoint of facilitating the understanding of the battery location information 270, for example, in the pop-up 310 of the post-selection screen 300 shown in Figure 4, for example, a map 330 and pins indicating the current locations of the batteries placed on the map 330 may be displayed on the display unit D. In this case, the map 330 may display only the pin indicating the current location of the first battery, for example, or it may display the current locations of other batteries in addition to the first battery.

[0075] As described above, the information displayed on the display unit D by the display control step may be rearranged in any order. For example, in the display control step, multiple relocation location information 130 may be arranged in order of priority according to the grade information 170 and displayed on the display unit D. Here, the priority may be in order of the highest battery performance, or in order of the highest battery performance. Specifically, for example, if the vertical order of the "Grade" column displayed on the display unit D is random, the user can select the item name "Grade" to rearrange the arrangement of each row so that the vertical order of the "Grade" column is in ascending or descending order. In the example shown in Figure 3, each row is arranged so that the vertical order of the "Grade" column is in ascending order. In the example shown in Figure 3, the priority is in order of the highest performance.

[0076] The method for obtaining the above information (battery identification information 110, relocation destination information 130, installation location information 140, original location information 120, worker identification information 150, spare part identification information 160, grade information 170, requested grade information 280, operating status information 180, replacement feasibility information 210, replacement time 220, power supply status information 190, charge amount information 230, transport time, size information, weight information 240, guide information 250, transport status information 260, location information 270) is not limited. In this embodiment, the above information is obtained as follows.

[0077] In this embodiment, information regarding the battery's most recent installation location (source location information 120), grade information 170, charge amount information 230, size information, weight information 240, and guide information 250 are stored in the storage unit 20 in association with the battery identification information 110. Hereafter, the information stored in the storage unit 20 in association with the battery identification information 110 may be referred to as the battery database. The grade information 170 changes each time a grade evaluation is performed, and the charge amount information 230 changes depending on the battery's usage status. Therefore, the grade information 170 is updated as appropriate by the grade evaluation, and the charge amount information 230 is updated at regular intervals when the receiving unit 31 receives the latest information, and stored in the storage unit 20. In addition, in this embodiment, the requested grade information 280 is stored in the storage unit 20 in association with location information (destination location information 130), which is the customer's location. Hereafter, the information stored in the storage unit 20, linked to the customer's location information (relocation destination information 130), may be referred to as the customer database. In this embodiment, the installation location information 140, spare parts identification information 160, and worker identification information 150 are stored in the storage unit 20.

[0078] Therefore, the battery identification information 110, source location information 120, grade information 170, charge amount information 230, size information, weight information 240, guide information 250, destination location information 130, required grade information 280, installation location information 140, spare parts identification information 160, and worker identification information 150 may be obtained from data stored in the storage unit 20.

[0079] In this embodiment, the operating status information 180, replacement feasibility information 210, replacement time 220, and power supply status information 190 change as needed depending on the power supply status of the first battery-1 that is scheduled to be replaced with the first battery, or the operating status of the rack in which the first battery-1 is installed. Therefore, the operating status information 180, replacement feasibility information 210, replacement time 220, and power supply status information 190 may be obtained by the receiving unit 31 receiving information at the most recent information update time.

[0080] In this embodiment, the transport status information 260 and the location information 270 change as the battery is transported and moved. Therefore, the transport status information 260 and the location information 270 may be obtained by the receiving unit 31 receiving information at the most recent information update time. Specifically, for example, the transport status information 260 may be updated when the worker in charge of transport inputs "departure," "transporting," or "arrival." For example, the location information 270 may be updated by obtaining the location of the battery using GPS.

[0081] The display control method of this embodiment involves repeatedly transporting each of the multiple storage batteries to the location of a customer who desires a storage battery with a specific evaluation, according to the evaluation corresponding to the performance of each battery.

[0082] In this case, the method for determining the relocation destination of the battery is not limited. Based on the performance of multiple battery systems, the grade of battery required by each customer, and the number of battery systems required by each customer, for example, an AI may determine the optimal combination of battery systems and customers, and the relocation destination of the battery system may be determined. Alternatively, based on the performance of multiple battery systems, the grade of battery required by each customer, and the number of battery systems, for example, an AI may present candidate combinations of battery systems and customers, and the user may decide on a combination. The control unit 30 may determine the optimal combination of such batteries and customers based on the battery database and customer database stored in the storage unit 20.

[0083] For example, if AI presents candidate combinations of a battery and a customer, and the user decides on a combination, the display unit D displayed in the display control step may display multiple relocation location information 130 corresponding to the first battery identification information 110. In this case, the relocation location information 130 indicates information about locations where the battery can potentially be relocated. Specifically, for example, multiple first relocation location information 130 indicating the relocation location of the first battery may be displayed, such as "Location A2", "Location A3", and "Location A4". In the selection step, if the user selects, for example, Location A from among the multiple relocation location information 130, the screen shown in Figure 3 may be displayed in the display control step, and "Location A2" may be determined as the first relocation location information 130 indicating the relocation location corresponding to the first battery.

[0084] The transportation time may be calculated and obtained after the combination of the battery and its destination has been determined.

[0085] As described above, the display control method of the present disclosure includes a display control step of displaying on the display unit D, in association with first battery identification information 110 that identifies the first battery and relocation location information 130 that indicates the location of the relocation destination of the first battery, which is the location of the customer who will use the first battery.

[0088] In addition, during the display control step, worker identification information 150, which identifies the worker who will transport the first battery to the relocation site, may be displayed on the display unit D together with the first battery identification information 110 and the relocation site information 130. With this configuration, users can determine the relocation site of the first battery by checking the relocation site information 130, and they can also identify the workers who will transport the first battery to the relocation site by checking the worker identification information 150. Therefore, users can easily understand who should transport the first battery, as indicated by the first battery identification information 110, to where. Thus, users can easily obtain information regarding the relocation of the battery.

[0089] Furthermore, in the display control step, spare part identification information 160 indicating spare parts for the first battery may be displayed on the display unit D together with the first battery identification information 110 and the relocation destination information 130. With this configuration, the user can determine the relocation location of the first battery by checking the relocation location information 130, and can also identify spare parts for the first battery by checking the spare parts identification information 160. Therefore, the user can easily determine where to transport the first battery, and can also easily determine which spare part (spare battery) to use as a replacement if the first battery becomes unavailable for any reason. Thus, the user can easily obtain information regarding the relocation of the battery.

[0090] Furthermore, in the display control step, grade information 170 indicating the degree of deterioration of the first battery may be displayed on the display unit D together with the first battery identification information 110 and the relocation destination information 130. With this configuration, the user can determine the relocation destination of the first battery by checking the relocation destination information 130, and can also determine the degree of degradation of the first battery by checking the grade information 170. Therefore, the user can easily determine the grade of the first battery indicated by the first battery identification information 110, and can easily determine where to transport this first battery. Thus, the user can easily obtain information regarding the relocation of the battery.

[0091] Furthermore, the relocation information may indicate multiple locations. For example, there may be multiple relocation sites where the first battery storage system could potentially be used. With the configuration described above, the user can easily identify the candidate locations (relocation destinations) to which the first battery should be transported, as indicated by the first battery identification information 110. Therefore, the user can easily obtain information regarding the relocation of the battery.

[0092] In addition, during the display control step, the grade information 170 corresponding to the first battery indicated by the first battery identification information 110 and the requested grade information 280 requested by each customer corresponding to each of the multiple relocation location information 130 may be displayed on the display unit D in association with each other. With this configuration, the user can understand the grade information 170 corresponding to the first battery by checking the first battery identification information 110, and can understand the grade of battery required by each customer corresponding to each of the multiple relocation destination information 130 by checking the requested grade information 280. Therefore, the user can easily understand where it is desirable to transport the first battery indicated by the first battery identification information 110, based on the grade required by each of the multiple customers (requested grade information 280). Thus, the user can easily understand information regarding the relocation of the battery.

[0093] Furthermore, in the display control step, the multiple relocation destination information 130 may be arranged in order of priority according to the grade information 170 and displayed on the display unit D. With this configuration, users can easily understand the correspondence between the relocation location information 130 and the priority order by checking the multiple relocation location information 130, which are arranged in order of priority according to the grade information 170. Therefore, users can appropriately understand where to transport the first battery indicated by the first battery identification information 110, according to the grade information 170 of that first battery. Thus, users can easily understand information regarding the relocation of batteries.

[0094] In addition, during the display control step, operating status information 180 indicating the current operating status of the rack on which the first battery is mounted may be displayed on the display unit D together with the first battery identification information 110 and the relocation destination information 130. When installing the first battery at the new location (for example, a rack), if the battery already installed in the rack is discharging, the first battery cannot be installed in the rack. With the configuration described above, the user can determine the relocation location of the first battery by checking the relocation location information 130, and can also determine the current operating status of the rack on which the first battery is installed by checking the operating status information 180. Therefore, the user can easily determine whether or not it is acceptable to install the first battery, indicated by the first battery identification information 110, in the corresponding installation location (rack). Thus, the user can easily obtain information regarding the relocation of the battery.

[0095] In addition, during the display control step, the display unit D may display, along with the first battery identification information 110 and the relocation destination information 130, exchangeability information 210 indicating whether the first battery is in a state where it can be exchanged with the first-1 battery already installed in the rack on which the first battery is mounted. With this configuration, users can determine the relocation location of the first battery by checking the relocation location information 130, and can also determine whether the first battery is interchangeable with the first-1 battery already installed in the rack where the first battery is to be installed by checking the interchangeability information 210. Therefore, users can easily obtain information regarding the relocation of batteries.

[0096] In addition, during the display control step, the first battery may be displayed on the display unit D along with the first battery already installed in the rack on which the first battery is mounted, the replaceable time information 220 indicating the time when the first battery will be replaceable, the first battery identification information 110, and the relocation destination information 130. With this configuration, the user can determine the relocation location of the first battery by checking the relocation location information 130, and can also determine the time when the first battery and the first-1 battery already installed in the rack where the first battery will be mounted will become interchangeable. Therefore, the user can easily determine the time when the first battery, as indicated by the first battery identification information 110, will become interchangeable with the first-1 battery already installed in the rack. Thus, the user can easily obtain information regarding the relocation of batteries.

[0097] Furthermore, in the display control step, the display unit D may display energization status information 190, which indicates whether or not the first-1 battery to be replaced with the first battery is energized, together with the first battery identification information 110 and the relocation destination information 130. When replacing the 1st-1 battery with the 1st battery at the relocation site, if the 1st-1 battery is currently energized, it is not possible to replace the energized 1st-1 battery with the 1st battery. With the configuration described above, the user can determine the relocation location of the first battery by checking the relocation location information 130, and can also determine whether the first-1 battery to be replaced with the first battery is energized by checking the power status information 190. Therefore, the user can easily determine whether the first battery indicated by the first battery identification information 110 and the first-1 battery to be replaced can be safely replaced. Thus, the user can easily obtain information regarding the relocation of the batteries.

[0098] Furthermore, the first-1 battery, which is replaced with the first battery, may be de-energized if the power status information 190 displayed on the display unit D is operated by a worker during the display control step. With this configuration, the user (worker) can easily de-energize the first battery to be replaced. For example, even if the first-first battery to be replaced is energized, the user can de-energize the first-first battery by operating the energization status information 190 displayed on the display unit D, allowing the worker to replace the first-first battery with the first battery at any time. Thus, the user can easily grasp information regarding the relocation of the batteries, and the battery relocation work can be easily carried out.

[0099] In addition, during the display control step, charge amount information 230 indicating the charge amount of the first battery and the charge amount of the first-1 battery to be replaced with the first battery may be displayed on the display unit D together with the first battery identification information 110 and the relocation destination information 130. When a battery is nearly 100% charged, it may discharge during transport or storage. With the configuration described above, the user can determine the relocation destination of the first battery by checking the relocation destination information 130, and can also determine the charge levels of the first battery and the 1-1 battery by checking the charge level information 230. Therefore, when transporting or storing the first battery and the 1-1 battery, the user can easily confirm whether the charge levels of the first battery and the 1-1 battery are appropriate.

[0100] Furthermore, in the display control step, the charge amount information 230 and the transport time of the first battery and the 1-1 battery may be displayed in correspondence on the display unit D. The appropriate charge level for a battery when transporting and storing it varies depending on the transport time and storage period. With the configuration described above, the user can determine whether the charge levels of the first battery and the first-1 battery are appropriate for the transport time of the first battery and the first-1 battery by checking the transport time and the charge level information 230.

[0101] Furthermore, in the display control step, at least one of size information indicating the size of the first battery and weight information 240 indicating the weight of the first battery may be displayed on the display unit D together with the first battery identification information 110 and the relocation destination information 130. With this configuration, users can determine the size of the first battery by checking the size information. Alternatively, users can determine the weight of the first battery by checking the weight information 240. Therefore, even if the worker (user) responsible for transporting the first battery is not a specialist in battery transport, they can understand the size and weight of the first battery by checking the size information or weight information 240. Thus, users can easily grasp information related to the relocation of the battery, and the battery relocation work can be carried out easily.

[0102] In addition, during the display control step, guide information 250 indicating how to replace the first battery may be displayed on the display unit D together with the first battery identification information 110 and the relocation destination information 130. The method for replacing a battery may vary depending on the type of battery, for example. With the configuration described above, users can determine the relocation site of the first battery by checking the relocation site information 130, and they can also understand how to replace the first battery by checking the guide information 250. Therefore, users can easily obtain information regarding the relocation of the battery, and the relocation work can be easily carried out.

[0103] Furthermore, in the display control step, transport status information 260 indicating the transport status of the first battery may be displayed on the display unit D together with the first battery identification information 110 and the relocation destination information 130. Users who check the information displayed on the display unit D using the display control method of this disclosure include not only workers who actually transport and install the battery, but also monitors who remotely monitor the transport and installation of the battery. It is preferable for the monitor to check, for example, the status of battery transport, such as whether the battery has departed from the source, is in transit, or has arrived at the destination. With the configuration described above, the user (monitor) can determine the relocation site of the first battery by checking the relocation site information 130, and can also understand the transportation status of the first battery by checking the transportation status information 260.
