The communication unit 230 includes a wired or wireless communication interface capable of communicating with the terminal device 122 (or the terminal device 131 depending on the configuration) via a communication network.

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

The DB 222 is a DB that stores battery information regarding the battery 121 acquired from the charging station 120 . This battery information is used to evaluate the state of deterioration of the battery, and a detailed description will be given later. The processing unit 210 manages the battery 121 by referring to battery information at each charging station. Note that the DB 221 and the DB 222 may be implemented as separate DBs, collectively as one DB, or further divided into a plurality of DBs and implemented.

FIG. 3 is a block diagram showing an example of the configuration of the terminal device 122. As shown in FIG. The terminal device 122 includes a processing section 310 , a storage section 320 , a communication section 330 and a display section 340 . The processing unit 310 is a central processing unit such as a CPU, and executes programs stored in the storage unit 320 to perform various processes. The storage unit 320 is a storage device such as RAM, ROM, or hard disk. The programs stored in the storage unit 320 include an application program for 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 apparatus 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 can display processing results such as information indicating the battery to be provided. Further, 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 to present the processing result to the user. In this embodiment, the information processing device 110 and the terminal device 122 are described as separate devices. Also, part 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 will be described below. The information processing device 110 acquires performance information including the deterioration state of each battery 121 . Charging station 120 determines a combination of batteries to be provided based on performance information in response to a user's request to provide two or more batteries. When providing multiple batteries, providing batteries with the same level of discharge performance after considering the state of deterioration, the performance status of the batteries used at the same time will become uneven, resulting in a decrease in energy efficiency and a decrease in battery capacity. It is possible to suppress acceleration of deterioration.

Here, the information processing device 110 acquires information (battery information) on 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 state of deterioration from the initial (new) state of the battery 121, and can be indicated by, for example, an evaluation value SOH (State of Health) of the deterioration state. SOH is calculated as a ratio of the current FCC to the initial full charge capacity FCC, for example, in the range of 1 to 110%. The method for evaluating the SOH is not particularly limited as long as it can evaluate the state of deterioration of the battery. may be calculated.

Therefore, the charging station 120 acquires battery information from each battery 121 . Battery information is information used to evaluate the SOH of the battery. Here, as the battery information, current information, history information, or individual information of the battery can be used. The battery current information is, for example, total voltage information, cell voltage information, or cell temperature information. Further, the current information of the battery 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 deterioration state SOH. good.

The charging and consumption state of the battery changes according to factors related to various usage conditions, such as the temperature during charging or during use, and the total charging (usage) time. Therefore, by using a model that handles time-series data such as a recursive neural network, it is possible to evaluate the SOH and the discharge time until the end of the discharge after considering such past usage information (history information). becomes possible. The history information of the battery may be, for example, information indicating the charge time or discharge time (total or last used), information indicating the average discharge load, or information indicating the maximum temperature reached. It may be the temperature information of the ambient environment during discharge. Also, the history information may be information indicating the date and time of the previous charge or discharge, or may be history information of the connected device. The battery individual information may be information indicating the battery type (model number, etc.), manufacturing date information, serial number, firmware information, or the like. Some or all of this information may be obtained from the battery 121 as battery information, or may be provided from outside the battery 121 . For example, the 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. FIG.

Also, the battery information may include information obtained during charging of the battery 121 at the charging station 120 . For example, charging station 120 may obtain DC internal resistance DCIR as battery information. DCIR can be calculated based on variations in battery voltage due to current injection (inflow) such as micro current charging (discharging) and normal charging (discharging). Further, charging station 120 may acquire a charging characteristic curve, current charging capacity, temperature rise characteristic, and the like as battery information. The charge characteristic curve and the current charge capacity can be measured, for example, by charge measurements during direct charging of the battery 121 . The charging station 120 can also evaluate the temperature information characteristics from the temperature information of the cells of the charging current.

FIG. 4 is a block diagram of the battery 121 in this embodiment. The battery 121 includes a battery cell 400 that is a power storage device and a management device 410 . Management device 410 includes control unit 420 . The control unit 420 includes a processing unit 421 , a storage unit 422 and an interface unit (I/F unit) 423 .

The management device 410 includes a code reader 430. Code reader 430 is, for example, a camera. In the case of this embodiment, the management device 410 reads the usage authorization code with the code reader 430 and authorizes the charging and discharging of the battery cell 400 after authentication. The use 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 license code on the display section of the terminal device 131 and causes the code reader 430 to read it. The usage permission code includes the ID of the battery 121 that can be used and the usage conditions of the battery 121 . Usage conditions can include the period during which the battery 121 can be used, the type of electrical equipment in which the battery 121 can be used, and the like. The control unit 420 collates the information contained in the usage authorization code read by the code reader 430 with the information stored in the storage unit 422, and authenticates the battery 121 for use.

The management device 410 includes a GPS (Global Positioning System) sensor 440. GPS sensor 440 is a sensor that detects the current position of battery 121 . If the area where the battery 121 can be used is limited, the management device 410 can check whether the battery 121 is used in the area where the battery 121 can be used based on the position information of the GPS sensor 440 .

The management device 410 includes an in-use sensor 450 . The in-use sensor 450 measures values that occur when the battery cell 400 is used in various ways, such as the charge/discharge amount of the battery cell 400 . Accordingly, the control unit 420 can measure battery information including history information. The in-use sensor 450 measures various values related to history information, such as the total charge/discharge amount of the battery 121 and temperature information during charging/discharging, and stores them in the storage 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 has a cutoff circuit 460 . Cutoff circuit 460 electrically connects or disconnects the electrical device in which battery 121 is mounted and battery cell 400 . For example, if the authorization code has not been authenticated, the cutoff circuit 460 is cut off. This disables the power supply of the battery 121 to the electrical equipment. In addition, the cutoff circuit 460 can be set to the cutoff state in the case of use contrary to the usage conditions included in the use authorization code. In this case as well, power supply from the battery 121 to the electrical equipment is disabled.

The management device 410 includes a communication unit 470. Communication unit 470 includes a wireless communication device and communicates with information processing apparatus 110 via a communication network. The DB 223 contains information necessary for communication of each battery 121 with the management device 410 . The management device 410 has a display device 480 . The display device 480 is a light-emitting element or liquid crystal display device, and presents information to the user of the battery 121 . Management device 410 includes communication unit 490 . The communication unit 490 connects the electrical equipment to which the battery 121 is mounted and the management device 410 by wire. The management device 410 can communicate with the electrical equipment via the communication unit 490, and can obtain, for example, information on the type of the electrical equipment from the electrical equipment. If there are restrictions on the type of electrical equipment under the rental conditions, and the battery 121 is used in the electrical equipment that does not meet the rental conditions, the control unit 420 can set the cutoff circuit 460 to the cutoff state. This disables the power supply of the battery 121 to the electrical equipment.

As described above, charging station 120 determines the combination of batteries to be provided based on performance information including the state of deterioration of each battery. Hereinafter, the term "combination" simply refers to this combination of provided batteries. For example, the charging station 120 can evaluate the discharge time to end of discharge (end of discharge characteristics) of each of the batteries 121 and determine the combination by comparing their end of discharge characteristics. By determining a combination of batteries whose discharge times to the end of discharge are close to each other, it is possible to provide the user with batteries that can be considered to have approximately the same performance state after considering the state of deterioration. Here, for example, the charging station 120 may determine a combination of batteries whose discharge time is within a predetermined range among the stored batteries 121, and the batteries that are consecutive in order of discharge time are selected as a combination. may decide.

The calculation method of the end-of-discharge characteristics according to the present embodiment is not particularly limited as long as the discharge time is evaluated in consideration of the state of deterioration. For example, the charging station 120 can provide the user with batteries that are close to the state of deterioration by determining a combination of the batteries 121 with similar SOH. This is an effective evaluation method for end-of-discharge characteristics when providing a battery in a fully charged state. Considering such a case, information processing apparatus 110 may estimate the end-of-discharge characteristics of each battery using a machine learning model trained using past learning data so as to estimate end-of-discharge characteristics from battery information. good. Further, the information processing device 110 may evaluate the end-of-discharge characteristics by calculation processing using SOH and SOC.

FIG. 5 is a diagram for evaluating end-of-discharge characteristics by exemplifying charge 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 SOC (%) on the y-axis and discharge time (t) on the x-axis. The battery 121a is less deteriorated than the battery 121b, and can be discharged for a longer period of 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 match those of fully charged battery 121b. In this way, by referring to the charge characteristic curve of each battery, it is possible to determine whether or not the end-of-discharge characteristics of the batteries at the current SOC are at the same level even if the deterioration states of the batteries are different. . This charging characteristic curve can be estimated using a machine learning model as described above.

In FIG. 5, the dashed line indicates that when the battery 121a is A %, it is determined that the end-of-discharge characteristics of the fully charged battery 121b are approximately the same. A certain range may be used for determination of the same level. For example, the information processing apparatus 110 sets a predetermined threshold for the discharge time, and when the absolute value of the difference in discharge time from the current state of charge of the two batteries is equal to or less than the threshold, the end-of-discharge characteristics are similar. It can be determined that there is This threshold may be set in advance as an allowable range, may be calculated by learning, or may be set by the user.

As described above, when providing fully charged batteries 121, the charging station 120 may provide a combination of batteries 121 with similar SOH. In order to select batteries with close SOHs, charging station 120 may select a combination of batteries 121 such that each SOH falls within a predetermined range, and may select combinations of batteries 121 so that they are consecutive in order of SOH value. You may choose. For example, the charging station 120 may select the first battery 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. can. The threshold value used in this example may be preset as an allowable range, may be calculated by learning, or may be set by the user.

In this embodiment, the charging station 120 refers to and provides information on the driving device used by the user, which is associated with the user who requested the supply of the battery (required when using the driving device). set the number of batteries and perform the combination. Here, the charging station 120 acquires the required battery performance information conditions from the drive device information, and selects one of the batteries 121 that satisfies the condition as one of the combinations. good too. Charging station 120 may then select the remaining batteries in the combination based on the performance information of the selected battery. The charging station 120 may, for example, satisfy the required battery performance information condition when the battery has sufficient charge capacity for the usage time of the battery estimated from the type of driving device. That is, the charging station 120 can acquire the expected usage time of the batteries from the type of drive device and determine a combination of the batteries 121 that can be used for that time.

The user 132 causes the terminal device 122 of the charging station 120 to obtain the above battery provision request. Basically, the user 132 transmits a provision request via an application running on the terminal device 131, but the user 132 may directly operate the terminal device 122 to make the provision request. Here, information indicating the user's ID is associated with the battery supply request, and the information processing apparatus 110 can refer to information about the driving device used by the user based on the user's ID. be.

FIG. 6 is a block diagram showing an example of the configuration of the terminal device 131. As shown in FIG. The terminal device 131 includes a processing section 610 , a storage section 620 , a communication section 630 , a display section 640 and an input section 650 . The processing unit 610 is a central processing unit such as a CPU, and executes programs stored in the storage unit 620 to perform various processes. The storage unit 620 is a storage device such as RAM, ROM, or hard disk. The programs stored in the storage unit 620 include user-side application programs for the battery providing service by the management system according to the present embodiment. This application program may be downloaded from a server such as the information processing apparatus 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 (with the information processing device 110 depending on the configuration) via a communication network. The display unit 640 is, for example, a liquid crystal display or a touch panel, and is capable of displaying results of various processes such as a screen for transmitting a battery provision request or information indicating a combination of provided batteries. The input unit 650 is a keyboard and mouse, or a touch panel that also serves as the display unit 640, and acquires user input. Note that the terminal device 131 may be implemented so as to perform some or all of the various processes performed by the terminal device 122 and the information processing device 110 .

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

FIG. 8 is a flowchart showing an example of processing performed by the charging station 120 according to the present embodiment when receiving a battery supply request from the user 132 . In S<b>801 , charging station 120 receives a battery supply request from user 132 . Here, the user 132 transmits a battery provision request via an application running on the terminal device 131 .

At S802, charging station 120 determines the number of batteries to be selected as a combination. Here, the charging station 120 acquires information on the driving device used by the user 132 from the information processing device 110 and determines the number of batteries used by the driving device as the number of combinations. The number of batteries may be specified in the provision request as shown, and so on. Also, the charging station 120 acquires the end-of-discharge characteristics required by the driving device used by the user 132 .

At S803, the charging station 120 checks whether the number of stored fully charged batteries 121 is greater than or equal to the number of batteries determined at S802. Here, it is assumed that the fully charged battery 121 has sufficient performance to operate the driving device. However, in the processing of S803, it is checked whether each battery in the fully charged state satisfies the end-of-discharge characteristics required by the driving device, and the number of batteries satisfying the characteristics is equal to or greater than the number of batteries determined in S802. It may be a process of confirming whether or not.

In S804, the charging station 120 provides the user with one of the stored batteries that satisfies the end-of-discharge characteristics required by the driving device used by the user 132 acquired in S802. Select as Here, it is assumed that a fully charged battery is preferentially selected.

In S805, the charging station 120 selects the rest of the battery combinations to be provided to the number of users determined in S802 from the stored batteries based on the performance information of the batteries selected in S804. Here, for example, in order to bring the discharge performance of the batteries to be used at the same time as close as possible, the batteries may be selected in descending order of the difference in end-of-discharge 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 process of S805. . On the other hand, if it is confirmed that the number of stored fully charged batteries is not equal to or greater than the number of batteries determined in S802, the remaining battery charge is determined according to the end-of-discharge characteristics considering the SOC and SOH values. A battery is selected. When the processing of S805 is completed, the series of processing is terminated, and the selected combination of batteries is provided to the user.

According to such processing, it is possible to evaluate the performance state of the batteries in consideration of the state of deterioration, and select a combination of batteries to be provided to the user based on the evaluation of the performance state. Therefore, it is possible to suppress the decrease in energy efficiency and the deterioration of the batteries due to the uneven performance of the batteries used simultaneously. In addition, by using batteries of similar performance at the same time, it is possible to equalize the level of deterioration of the batteries used. This facilitates various kinds of management according to the state of deterioration, such as management of battery replacement timing.

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

FIG. 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.

Each charging station according to the present embodiment is configured so that batteries to be stored are assigned by the information processing device, and batteries having the same degree of deterioration are stored. For example, the information processing device 910 sets a threshold used for evaluating the SOH, and stores 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. can be determined. This threshold value may be set as a desired value according to an operation policy based on the state of deterioration of the battery. In addition, the deterioration state can be classified into three stages, for example, high/medium/low deterioration state, and it is possible to prepare a plurality of charging stations corresponding to each of them, but the number of these divisions can be set arbitrarily. Also, the number of charging stations corresponding to one section is not particularly limited. After the charging stations stored for the battery are allocated, the battery is moved in/out between the charging stations. For each charging station, the processing after acquisition of the battery provision request from the user is performed in the same manner as in the first embodiment.

According to such a configuration, it is possible to determine the charging station where the battery is stored based on the evaluation value of the deterioration state. Therefore, deviations in the state of deterioration of the batteries are less likely to occur within the charging station, and management or operation costs can be reduced. In addition, charging stations that store batteries that have deteriorated and their operating time has decreased can be used to set the price of battery provision services, such as adding value as a charging station that handles batteries for short-distance driving. is.
