[Embodiment 1]
1 is a diagram showing an example of the configuration of a management system 100 including an information processing device 110 according to this embodiment. The management system 100 is a system that uses the information processing device 110 to manage performance information including the degradation state of batteries in a charging station, and selects a combination of batteries to be provided to a user based on the performance information of each battery. The information processing device 110 is, for example, a server or a database, and is communicatively connected to a plurality of charging stations 120 via a communication network such as the Internet.

The charging station 120 is a facility that stores and charges multiple batteries 121 that can be provided to users. Here, the charging station 120 includes multiple charging stations such as charging station 120a or 120b as shown in the figure, but when there is no need to distinguish between them, they will be collectively referred to as charging station 120. The charging station 120 acquires a battery provision request from a user and provides the user with a combination of batteries selected according to performance information. A detailed explanation of the battery selection process will be given later. Note that, hereinafter, when simply referred to as battery (121), it refers to the battery stored in the charging station 120.

The battery 121 is an energy storage device that provides power when attached to a drive unit, and is, for example, a lithium-ion battery. The terminal device 122 is an example of a communication terminal installed in the charging station 120, and may be, for example, a personal computer 122a that accepts operations by an administrator, or a control computer 122b of the charging station 120. The personal computer 122a corresponds to the charging station 120a, and the control computer 122b corresponds to the charging station 120b.

The terminal device 131 is a communication terminal used by the user 132 who transmits a request to provide the battery 121, and may be, for example, a mobile terminal such as a smartphone, or a communication terminal such as a personal computer. The user 132 is a user of a driving device (not shown) that uses the battery 121, and various information input by the user 132 to the terminal device 131 is transmitted to the charging station 120 via a communication network. The driving device may have the functions of the terminal device 131. The driving device is not particularly limited as long as it is an equipment that can be driven by the battery 121, and may be, for example, an electric mobility such as an electric motorcycle, or an electric device such as a rammer or plate compactor. In this embodiment, the driving device used by the user 132 may be registered in association with the user 132 by the terminal device 131. In the example of FIG. 1, the terminal device 131a corresponding to the user 132a and the terminal device 131b corresponding to the user 132b are shown, but when there is no need to distinguish between them, they are collectively referred to as the user 132 and the terminal device 131, respectively.

Figure 2 is a block diagram showing an example of the configuration of the information processing device 110. The information processing device 110 comprises a processing unit 210, a memory unit 220, and a communication unit 230. The processing unit 210 is a central processing unit such as a CPU, and executes programs stored in the memory unit 220 to perform various processes. The memory unit 220 is a storage device such as a RAM, ROM, or hard disk. The communication unit 230 includes a wired or wireless communication interface capable of communicating with the terminal device 122 (or terminal device 131 depending on the configuration) via a communication network.

The memory unit 220 stores a database composed of various data in addition to the program executed by the processing unit 210. In the example of FIG. 3, the memory unit 220 stores databases (DB) 221 and 222. DB 221 is a DB in which information on the user 132 is registered. DB 221 accumulates various information used when the user 132 requests the provision of a battery, such as the identification information (ID) of the user 132 or information on the driving device used by the user.

DB222 is a DB that stores battery information regarding battery 121 obtained from charging station 120. This battery information is used to evaluate the deterioration state of the battery, which will be described in detail later. Processing unit 210 manages battery 121 by referring to the battery information in each charging station. DB221 and DB222 may be implemented as separate DBs, may be integrated into one DB, or may be implemented as multiple DBs.

Figure 3 is a block diagram showing an example of the configuration of the terminal device 122. The terminal device 122 includes a processing unit 310, a memory unit 320, a communication unit 330, and a display unit 340. The processing unit 310 is a central processing unit such as a CPU, and executes programs stored in the memory unit 320 to perform various processes. The memory unit 320 is a storage device such as a RAM, a ROM, or a hard disk. The programs stored in the memory unit 320 include an application program for a battery provision service provided by the management system according to this embodiment. This application program may be downloaded from a server such as the information processing device 110, or may be distributed on a storage medium such as a CD-ROM.

The communication unit 330 includes a wired or wireless communication interface capable of communicating with the information processing device 110 and the terminal device 131 via a communication network. The display unit 340 is, for example, a liquid crystal display or a touch panel, and is capable of displaying the results of processing, such as information indicating the battery to be provided. In addition, when the user 132 directly operates the terminal device 122, the display unit 340 may additionally include an input unit (not shown) such as a keyboard and a mouse, and may present the results of processing to the user. Note that, in this embodiment, the information processing device 110 and the terminal device 122 are described as separate devices, but, for example, each process performed by the information processing device 110 may be configured to be performed by the terminal device 122, and some of these processes may be performed by the terminal device 131.

The processing performed by the information processing device 110 and the charging station 120 is described below. The information processing device 110 acquires performance information, including the degradation state, for each battery 121. In response to a user request for the provision of two or more batteries, the charging station 120 determines the combination of batteries to provide based on the performance information. When providing multiple batteries, batteries with similar discharge performance taking into account the degradation state are provided, which makes it possible to suppress a decrease in energy efficiency and accelerated battery degradation caused by batteries used simultaneously having uneven performance states.

Here, the information processing device 110 acquires information (battery information) about each battery from the charging station 120, and estimates the deterioration state of the battery 121 based on the acquired battery information. The deterioration state of the battery 121 is information indicating the deterioration state from the initial (new) state of the battery 121, and can be indicated, for example, by an evaluation value SOH (State of Health) of the deterioration state. The SOH is calculated, for example, in the range of 1 to 110%, as the ratio of the current FCC to the initial full charge capacity FCC. The method of evaluating the SOH is not particularly limited as long as it can evaluate the deterioration state of the battery, but for example, the SOH may be acquired as current information of the battery, or the SOH may be calculated using a machine learning model based on the information of each battery.

To this end, the charging station 120 acquires battery information from each battery 121. The battery information is information used to evaluate the SOH of the battery. Here, the battery information may be current information, history information, or individual information of the battery. The current battery information may be, for example, overall voltage information, cell voltage information, or cell temperature information. In addition, the current battery information may be information indicating the state of charge SOC (State of Charge) of the battery, information indicating the full charge capacity FCC, or information indicating the degradation state SOH.

The charging and depletion state of the battery changes depending on factors related to various usage conditions, such as the temperature conditions during charging or use, and the total charging (use) time. Therefore, by using a model that handles time-series data, such as a recurrent neural network, it is possible to evaluate the SOH and the discharge time until the end of discharge, taking into account such past usage information (history information). The battery history information may be, for example, information indicating the charging time or discharging time (total or at the time of previous use), information indicating the average discharging load, information indicating the maximum temperature reached, or temperature information of the surrounding environment at the time of discharging. The history information may also be information indicating the date and time of the previous charging or discharging, or history information of the connected device. The individual information of the battery may be information indicating the type of battery (such as a model number), manufacturing date and time information, serial number, firmware information, or the like. Note that some or all of this information may be acquired from the battery 121 as battery information, but may also be provided from outside the battery 121. For example, information indicating the charging date and time may be information based on the internal clock of the battery 121, or may be information with higher accuracy, such as information calculated by an external device such as the charging station 120.

The battery information may also include information acquired during charging of the battery 121 in the charging station 120. For example, the charging station 120 may acquire direct current internal resistance DCIR as the battery information. DCIR can be calculated based on the fluctuation in battery voltage due to current injection (inflow) such as microcurrent charging (discharging) and normal charging (discharging). The charging station 120 may also acquire a charging characteristic curve, a current charging capacity, a temperature rise characteristic, and the like as the battery information. The charging characteristic curve and the current charging capacity can be measured, for example, by a charging measurement method during direct charging of the battery 121. The charging station 120 can also evaluate temperature information characteristics from the temperature information of the cells in the charging current.

Figure 4 is a block diagram of the battery 121 in this embodiment. The battery 121 comprises a battery cell 400, which is a power storage device, and a management device 410. The management device 410 includes a control unit 420. The control unit 420 includes a processing unit 421, a memory unit 422, and an interface unit (I/F unit) 423. The processing unit 421 is a processor, such as a CPU, and executes a program stored in the memory unit 422.

The memory unit 422 is a storage device such as a RAM or a ROM. In addition to the program executed by the processing unit 421, various information is stored in the memory unit 422. Examples of the various information include individual information of the battery 121 contained in the battery information, the current status, or history information. The I/F unit 423 relays the transmission and reception of signals between the processing unit 421 and external devices.

The management device 410 includes a code reader 430. The code reader 430 is, for example, a camera. In this embodiment, the management device 410 reads the usage permission code with the code reader 430, and authorizes the battery cell 400 to be charged or discharged. The usage permission code is, for example, a two-dimensional code, and is transmitted from the information processing device 110 to the terminal device 131 of the user 132. The user 132 displays the received usage permission code on the display unit of the terminal device 131 and has the code reader 430 read it. The usage permission code includes the ID of the usable battery 121 as well as the usage conditions of the battery 121. Examples of the usage conditions include the period during which the battery 121 can be used and the type of electrical equipment for which the battery 121 can be used. The control unit 420 compares the information included in the usage permission code read by the code reader 430 with the information stored in the memory unit 422, and authorizes the use of the battery 121.

The management device 410 is equipped with a GPS (Global Positioning System) sensor 440. The GPS sensor 440 is a sensor that detects the current location of the battery 121. If there are restrictions on the area in which the battery 121 can be used, the management device 410 can check whether the battery 121 is being used in the area in which it can be used, based on the location information of the GPS sensor 440.

The management device 410 is equipped with a usage sensor 450. The usage sensor 450 measures values that occur during various uses of the battery cell 400, such as the charge/discharge amount of the battery cell 400. This allows the control unit 420 to measure battery information including history information. The usage sensor 450 measures various values related to history information, such as the total amount of charge/discharge of the battery 121 and temperature information during charging/discharging, and stores this in the memory unit 422 as the latest battery information. This battery information is provided to the information processing device 110 and used to calculate the SOH.

The management device 410 includes a cutoff circuit 460. The cutoff circuit 460 electrically connects and cuts off the connection between the electrical device to which the battery 121 is attached and the battery cell 400. For example, if the usage permission code is not authenticated, the cutoff circuit 460 is set to a cutoff state. This disables the battery 121 from supplying power to the electrical device. The cutoff circuit 460 can also be set to a cutoff state if the battery is used in a manner that violates the usage conditions included in the usage permission code. In this case as well, the battery 121 is unable to supply power to the electrical device.

The management device 410 includes a communication unit 470. The communication unit 470 includes a wireless communication device and communicates with the information processing device 110 via a communication network. The DB 223 includes information necessary for communication between each battery 121 and the management device 410. The management device 410 includes a display device 480. The display device 480 is a light-emitting element or a liquid crystal display device, and presents information to the user of the battery 121. The management device 410 includes a communication unit 490. The communication unit 490 connects the electrical device to which the battery 121 is attached and the management device 410 by wire. The management device 410 can communicate with the electrical device via the communication unit 490, and can obtain, for example, information on the type of electrical device from the electrical device. If the type of electrical device is restricted under the lending conditions, when the battery 121 is used for an electrical device outside the lending conditions, the control unit 420 can also shut off the cutoff circuit 460. This makes it impossible for the battery 121 to supply power to the electrical device.

As described above, the charging station 120 determines the combination of batteries to be provided based on the performance information including the deterioration state of each battery. Hereinafter, when simply written as "combination", it refers to this combination of provided batteries. For example, the charging station 120 can determine the combination by evaluating the discharge time until the end of discharge of each battery 121 (end-of-discharge characteristics) and comparing the end-of-discharge characteristics. By determining a group of batteries with similar discharge times until the end of discharge as a combination, it is possible to provide the user with batteries that can be considered to have similar performance states while taking into account the deterioration state. Here, for example, the charging station 120 may determine the combination from batteries with discharge times within a predetermined range among the stored batteries 121, or may determine the combination from batteries that are consecutive in order of discharge time.

The calculation method of the end-of-discharge characteristics according to this embodiment is not particularly limited as long as it is evaluated as a discharge time taking into account the deterioration state. For example, the charging station 120 can provide a user with batteries with similar deterioration states by determining a combination of batteries 121 with similar SOH. This is an evaluation method of the end-of-discharge characteristics that is particularly effective when providing a battery in a fully charged state, but in some cases, it is also possible to use a battery that is not fully charged. In consideration of such cases, the information processing device 110 may estimate the end-of-discharge characteristics of each battery using a machine learning model trained using past learning data to estimate the end-of-discharge characteristics from the battery information. The information processing device 110 may also evaluate the end-of-discharge characteristics by calculation processing using the SOH and SOC.

5 is a diagram for evaluating the end-of-discharge characteristics by illustrating charging characteristic curves for batteries with different deterioration states. In the example of FIG. 5, charging characteristic curves for batteries 121a and 121b with different SOH are displayed, with the y-axis representing SOC (%) and the x-axis representing discharge time (t). Battery 121a is less deteriorated than battery 121b, and can be discharged for a longer time from the fully charged state to the end of discharge. On the other hand, when the SOC of battery 121a is A%, the end-of-discharge characteristics will match those of battery 121b in the fully charged state. In this way, by referring to the charging characteristic curves of each battery, it is possible to determine whether the end-of-discharge characteristics will be similar at the current SOC even for batteries with different deterioration states. This charging characteristic curve can be estimated using a machine learning model as described above.

In FIG. 5, when battery 121a is at A%, it is determined that the end-of-discharge characteristics are similar to those of battery 121b, which is in a fully charged state, as indicated by the dotted line, but this may be a perfect match, or the sameness may be determined within a certain range. For example, the information processing device 110 may set a predetermined threshold value for the discharge time, and may determine that the end-of-discharge characteristics of the two batteries are similar when the absolute value of the difference in discharge time from the current charge state is equal to or less than the threshold value. This threshold value may be preset as an acceptable range, may be calculated by learning, or may be set by the user.

As described above, when providing a fully charged battery 121, the charging station 120 may provide a combination of batteries 121 with similar SOH. To select batteries with similar SOH, the charging station 120 may select a combination of batteries 121 such that each SOH falls within a predetermined range, or may select a combination of batteries 121 such that the batteries are consecutive in order of SOH value. For example, the charging station 120 may select the first battery to be included in the combination, and select the remaining batteries such that the absolute value of the difference in SOH value from the first battery is equal to or less than a predetermined threshold. The threshold used here may be preset as an acceptable range, may be calculated by learning, or may be set by the user.

In this embodiment, the charging station 120 refers to the information of the drive device used by the user who has requested the provision of the batteries, and sets the number of batteries to be provided (required when using the drive device) and performs the combination. Here, the charging station 120 may obtain the condition of the performance information of the required battery from the information of the drive device, and select one battery that satisfies the condition from among the batteries 121 as one of the combinations. The charging station 120 may then select the remaining battery of the combination based on the performance information of the selected battery. For example, the charging station 120 may determine that the condition of the performance information of the required battery is satisfied when the battery has sufficient charging capacity for the usage time of the battery estimated from the type of the drive device. In other words, the charging station 120 can obtain the expected usage time of the battery from the type of the drive device, and determine the combination from among the batteries 121 that can be used during that time.

The user 132 causes the terminal device 122 of the charging station 120 to obtain a battery supply request as described above. Basically, the user 132 transmits the supply request via an application running on the terminal device 131, but the supply request may also be made by directly operating the terminal device 122. Here, the battery supply request is linked to information indicating the user's ID, and the information processing device 110 can refer to information on the drive device used by the user based on the user's ID.

Figure 6 is a block diagram showing an example of the configuration of the terminal device 131. The terminal device 131 comprises a processing unit 610, a memory unit 620, a communication unit 630, a display unit 640, and an input unit 650. The processing unit 610 is a central processing unit such as a CPU, and executes programs stored in the memory unit 620 to perform various processes. The memory unit 620 is a storage device such as a RAM, a ROM, or a hard disk. The programs stored in the memory unit 620 include a user-side application program for the battery provision service by the management system according to this embodiment. This application program may be downloaded from a server such as the information processing device 110, or may be distributed on a storage medium such as a CD-ROM.

The communication unit 630 includes a wired or wireless communication interface capable of communicating with the terminal device 131 (or with the information processing device 110 depending on the configuration) via a communication network. The display unit 640 is, for example, an LCD display or a touch panel, and is capable of displaying the results of various processes, such as a screen for transmitting a request for battery provision, or information indicating the combination of batteries to be provided. The input unit 650 is a keyboard and mouse, or a touch panel that also serves as the display unit 640, and acquires input from the user. The terminal device 131 may be implemented to perform some or all of the various processes performed by the terminal device 122 and the information processing device 110.

Figure 7 shows an example of a GUI for sending a battery supply request, displayed on the display unit 640. In the example of Figure 7, in addition to a button 701 for sending the supply request and a button 702 for canceling the supply request, an input box 703 for inputting the number of batteries requested is displayed on the display unit 640. In this embodiment, information including the type of drive device is associated with the user's ID, and the number of batteries to be provided is determined by the information processing device 110 as the number of batteries used by that type of drive device, but the user may specify it in the input box 703.

Figure 8 is a flowchart showing an example of processing performed by the charging station 120 according to this embodiment when a battery provision request is received from the user 132. In S801, the charging station 120 receives the battery provision request from the user 132. Here, the user 132 transmits the battery provision request via an application running on the terminal device 131.

In S802, the charging station 120 determines the number of batteries to select as a combination. Here, the charging station 120 acquires information on the drive device used by the user 132 from the information processing device 110, and determines the number of batteries used by that drive device as the number of combinations, but the number of batteries may be specified in the provision request, for example, as shown in FIG. 7. The charging station 120 also acquires the end-of-discharge characteristics required by the drive device used by the user 132.

In S803, the charging station 120 checks whether the number of stored fully charged batteries 121 is equal to or greater than the number of batteries determined in S802. Note that here, it is assumed that the fully charged batteries 121 have sufficient performance to operate the drive device. However, the process of S803 may be a process of checking whether each fully charged battery meets the end-of-discharge characteristics required by the drive device, and checking whether the number of batteries that meet this requirement is equal to or greater than the number of batteries determined in S802.

In S804, the charging station 120 selects one battery from the stored batteries that satisfies the end-of-discharge characteristics required by the drive device used by the user 132 obtained in S802, as one of the combinations of batteries to be provided to the user. Here, a fully charged battery is selected with priority.

In S805, the charging station 120 selects the remaining battery combinations to be provided to the user, the number determined in S802, from among the stored batteries based on the performance information of the battery selected in S804. Here, for example, in order to make the discharge performance of the batteries used simultaneously as close as possible, the batteries may be selected in order of the smallest difference in discharge end characteristics from the battery selected in S804. If it is confirmed in S803 that the number of fully charged batteries stored is equal to or greater than the number of batteries determined in S802, the SOH values of the fully charged batteries are compared in the processing of S805. On the other hand, if it is confirmed that the number of fully charged batteries stored is not equal to or greater than the number of batteries determined in S802, the remaining batteries are selected according to the discharge end characteristics taking into account the SOC and SOH values. When the processing of S805 is completed, the series of processing is terminated, and the battery combination selected is provided to the user.

This type of processing allows the performance state of the batteries to be evaluated taking into account their degradation state, and the combination of batteries to be provided to the user can be selected based on the evaluation of the performance state. This makes it possible to suppress the decline in energy efficiency and accelerated battery degradation caused by batteries used simultaneously having different performance states. Furthermore, by using batteries with similar performance simultaneously, it is possible to equalize the degradation level of the batteries being used. This makes it easier to perform various types of management according to the degradation state, such as managing when to replace the batteries.

[Embodiment 2]
According to the management system of the first embodiment, it is possible to grasp the performance status, including the degradation status, of each battery stored in each charging station. Therefore, the management system according to the present embodiment manages the storage locations of each battery so that batteries with the same degree of degradation are placed in each charging station.

Figure 9 is a diagram showing an example of the configuration of a management system 900 including an information processing device 910 according to this embodiment. The information processing device 910 according to this embodiment is capable of performing processing similar to that of the information processing device 110 according to embodiment 1, and similar configurations are indicated by the same reference numbers, so duplicate explanations will be omitted.

The information processing device 910 determines a charging station to store the battery based on the evaluation value SOH of the battery's deterioration state. Each charging station according to this embodiment is configured to store batteries that are allocated by the information processing device and to store batteries with similar deterioration states. For example, the information processing device 910 can set a threshold value used for evaluating the SOH, and determine whether to store the battery in the charging station 120a or the charging station 120b depending on whether the SOH of the battery is greater than the threshold value. The value of this threshold value may be set as a desired value according to an operation policy based on the deterioration state of the battery. In addition, the deterioration state is classified into three stages, for example, high/medium/low deterioration state, and multiple charging stations corresponding to each of them can be prepared, but the number of these stages can be set arbitrarily, and the number of charging stations corresponding to one stage is not particularly limited. After the charging station to store the battery is allocated, the battery is transferred in/out between the charging stations. For each charging station, a battery provision request from the user is acquired and the subsequent processing is performed in the same manner as in embodiment 1.

With this configuration, it is possible to determine the charging station in which the battery will be stored based on the evaluation value of the deterioration state. This makes it less likely that deviations in the deterioration state of each battery will occur within the charging station, and it is possible to reduce management or operating costs. In addition, charging stations that store batteries with deteriorated and reduced operating time can be used to add value, for example as charging stations that handle batteries for short-distance driving, and can also be used in setting the price of the battery provision service.
