[0001] The present disclosure relates to a control technology, and more particularly to an information terminal device and a processing system that acquire information from a storage battery. [Background technology]

[0002] Recall-targeted battery packs are generally collected by manufacturers or the like. At that time, it is necessary to estimate the location of the recall-targeted battery pack. For this reason, a charger to which a battery pack can be attached and detached is provided with a communication function for communicating with a server device via a base station, and the charger transmits identification information of the battery pack to the server device. Based on the identification information of the battery pack, the server device determines whether the battery pack is subject to recall, and estimates the location of the battery pack based on the identification information of the base station that relayed the battery pack identification information (see, for example, Patent Document 1).

[0013] Example 1 Before specifically describing an embodiment of the present disclosure, an overview of the embodiment will be described. The embodiment relates to a charge / discharge system that enables charging / discharging of a battery pack by connecting the battery pack to a charge / discharge device. When the battery pack includes, for example, a lithium-ion secondary battery, various states of the lithium-ion secondary battery are acquired in the battery pack in order to safely use the battery pack. The various states are, for example, a remaining charge and an abnormal state. If such various information is transmitted from the battery pack to an information terminal device such as a smartphone by wireless communication, it becomes possible to check the various information on the information terminal device. For example, a short-range wireless communication system is used for the wireless communication.

[0014] However, when multiple battery packs are present near an information terminal device, usability is reduced unless the various states of each of the multiple battery packs can be immediately confirmed. For this reason, an application program for battery packs (hereinafter, referred to as "application") according to this embodiment has a function of acquiring various information about each of the multiple battery packs via wireless communication and visualizing the various information so that it can be viewed at a glance.

[0015] It is also preferable to be able to check the abnormal state of the charging / discharging device to which the storage battery pack is connected. However, in order to simplify the configuration of the charging / discharging device, the charging / discharging device is not equipped with a wireless communication function. Therefore, the charging / discharging device according to this embodiment outputs information on the abnormal state to the storage battery pack, and the storage battery pack transmits information on the charging / discharging device to the information terminal device. As a result, the application according to this embodiment has a function of visualizing information on the charging / discharging device to which the storage battery pack is connected. Here, this embodiment will be described in the order of (1) basic configuration, (2) state determination, (3) communication by a short-range wireless communication system, and (4) display of information.

[0016] (1) Basic configuration 1 shows the configuration of a charge / discharge system 1000. The charge / discharge system 1000 includes a first storage battery pack 100a to a third storage battery pack 100c collectively referred to as storage battery packs 100, a first charging / discharging device 200a to a third charging / discharging device 200c collectively referred to as charging / discharging devices 200, an information terminal device 300, a network 400, and a server device 500. The number of storage battery packs 100 and charging / discharging devices 200 is not limited to "3".

[0017] The storage battery pack 100 includes a secondary battery such as a lithium ion secondary battery, and manages the state based on various states of the lithium ion secondary battery. The storage battery pack 100 is detachable from the charge / discharge device 200, and when the storage battery pack 100 is attached to the charge / discharge device 200, the charge / discharge device 200 charges and discharges the storage battery pack 100, and also communicates between the storage battery pack 100 and the charge / discharge device 200. The storage battery pack 100 performs communication compatible with a short-range wireless communication system. Examples of the short-range wireless communication system include Bluetooth (registered trademark) and BLE (Bluetooth Low Energy).

[0018] The information terminal device 300 is, for example, a smartphone, a tablet terminal, or a PC. The information terminal device 300 is compatible with the same short-range wireless communication system as the storage battery pack 100, and can execute direct wireless communication with the storage battery pack 100. The information terminal device 300 is connected to a network 400, and can communicate with a server device 500 via the network 400. For example, a wireless communication system such as 5G or 4G is used for the network 400. The network 400 may also be combined with the Internet. In general, the communicable range of a wireless communication system is wider than the communicable range of a short-range wireless communication system. The information terminal device 300 executes an application program (hereinafter also referred to as an "application") for controlling the storage battery pack 100. Processing by the application will be described later.

[0019] The server device 500 is used by the manufacturer or business that produced the storage battery pack 100. The server device 500 is connected to the network 400, and executes, for example, a process for providing various information to an application.

[0020] Fig. 2 shows the configuration of the charging / discharging system 1000. Fig. 2 shows the configurations of the first storage battery pack 100a to the third storage battery pack 100c, the first charging / discharging device 200a to the third charging / discharging device 200c, and the information terminal device 300 in Fig. 1. The first storage battery pack 100a includes a storage battery 110, a control unit 120, a memory unit 130, a first communication unit 140, a notification unit 150, and an operation unit 180, and the control unit 120 includes a determination unit 160 and a second communication unit 170. The first charging / discharging device 200a includes a charging / discharging circuit 210, a control unit 220, a communication unit 230, a power plug 250, a power supply unit 260, a cooling fan 270, and a discharger 280, and the control unit 220 includes a reception unit 240. Information terminal device 300 includes a first communication unit 310, a control unit 320, a storage unit 330, a display unit 340, an operation unit 350, and a second communication unit 360, and control unit 320 includes an acquisition unit 322 and an output unit 324. Second storage battery pack 100b and third storage battery pack 100c have the same configuration as first storage battery pack 100a, and second charging / discharging device 200b and third charging / discharging device 200c have the same configuration as first charging / discharging device 200a.

[0021] The storage battery 110 of the storage battery pack 100 is a secondary battery such as a lithium ion secondary battery. The storage battery 110 is connected to and controlled by the control unit 120. The control unit 120 controls the overall operation of the storage battery pack 100. One example of the operation is the determination of the state of the storage battery 110 performed by the determination unit 160. In order to determine the state, the degree of deterioration of the storage battery 110 may be determined. The memory unit 130 stores a table used by the determination unit 160 when determining the state of the storage battery 110. The storage battery pack 100 is provided with a power supply unit (not shown), and the storage battery 110 may output power from the power supply unit. One example of the power supply unit is a USB (Universal Serial Bus) terminal.

[0022] The first communication unit 140 communicates with the information terminal device 300 by executing communication compatible with a short-range wireless communication system. The notification unit 150 is an interface for notifying the user of various information. The notification unit 150 includes, for example, a plurality of LEDs (Light Emitting Diodes) and changes the lighting pattern of the plurality of LEDs according to the content of the information. The second communication unit 170 is capable of executing serial communication such as RS-485, RS-422, RS-232C, etc., and communicates with the charging / discharging device 200 when the storage battery pack 100 is connected to the charging / discharging device 200. The operation unit 180 is an interface that can be operated by the user, for example, a button.

[0023] The power plug 250 of the charging / discharging device 200 is detachably connected to an external AC power source. When the power plug 250 is connected to the AC power source, the AC power source can supply AC power, for example, up to 330 W, to the charging / discharging device 200. When the power plug 250 is connected to the AC power source, if the storage battery pack 100 is connected to a connection portion (not shown) of the charging / discharging device 200, the charging / discharging circuit 210 of the charging / discharging device 200 converts the AC power from the power plug 250 into DC power to charge the storage battery 110.

[0024] The power supply unit 260 detachably connects an external electronic device. When an electronic device is connected to the power supply unit 260, the charging / discharging device 200 can supply AC power to the electronic device. When the electronic device is connected to the power supply unit 260, if the storage battery pack 100 is connected to a connection unit (not shown) of the charging / discharging device 200, the charging / discharging circuit 210 of the charging / discharging device 200 converts DC power from the storage battery 110 to AC power and outputs the AC power from the power supply unit 260. Even if the AC power source is interrupted, the charging / discharging circuit 210 of the charging / discharging device 200 converts DC power from the storage battery 110 to AC power and outputs the AC power from the power supply unit 260. At that time, the charging / discharging circuit 210 discharges the storage battery 110 to a first level. The first level is determined in advance.

[0025] The cooling fan 270 blows air to the charging / discharging circuit 210 by rotating. The air blowing suppresses a temperature rise in the charging / discharging circuit 210. The cooling fan 270 is not limited to cooling and may be a fan. The control unit 220 is connected to the charging / discharging circuit 210 and controls the overall operation of the charging / discharging device 200. The communication unit 230 can be connected to the second communication unit 170 and communicates with the storage battery pack 100 by the above-mentioned serial communication. For example, when the control unit 220 detects an abnormal state of the charging / discharging device 200, the control unit 220 causes the communication unit 230 to transmit information for notifying the storage battery pack 100 of the abnormal state of the charging / discharging device 200 (hereinafter referred to as a "charging / discharging device abnormality notification"). An example of an abnormal state of the charging / discharging device 200 is when the cooling fan 270 cannot rotate. Since a known technique may be used for detecting the abnormal state in the control unit 220, a description thereof will be omitted here.

[0026] The first communication unit 310 of the information terminal device 300 communicates with the storage battery pack 100 by executing communication corresponding to the short-range wireless communication system. The control unit 320 is connected to the first communication unit 310 and controls the overall operation of the information terminal device 300. The control unit 320 executes, for example, an application stored in the storage unit 330 to execute a process provided by the application. The display unit 340 is a display for displaying information, and the operation unit 350 is an interface for receiving instructions from a user. The display unit 340 and the operation unit 350 may be integrated as a touch panel. The second communication unit 360 communicates with the server device 500 via the network 400 in FIG. 1 by executing communication corresponding to the wireless communication system.

[0027] (2) Status determination The determination unit 160 of the control unit 120 measures various states of the storage battery 110, that is, the storage battery pack 100. The various states are, for example, the remaining battery capacity, the SOH (State Of Health), the average temperature of the storage battery, the internal resistance value of the storage battery, the time elapsed since the storage battery pack 100 was manufactured, the total charge amount, the total discharge amount, and the like. Here, the remaining battery capacity is the remaining capacity of the storage battery 110. The SOH indicates the ratio of the current full charge capacity to the initial full charge capacity of the storage battery 110, and corresponds to, for example, the learning capacity. The time elapsed since the storage battery pack 100 was manufactured is measured based on the difference between the current date acquired by a clock function provided in the determination unit 160 and the manufacturing date of the storage battery pack 100 stored in the memory unit 130. Since known techniques may be used for these measurements, a description thereof will be omitted here.

[0028] The determination unit 160 determines the state of the storage battery pack 100 based on various measured states while referring to a table stored in the storage unit 130. An example of the state is the deterioration level, which is a value indicating the degree to which the storage battery pack 100 has deteriorated from an initial state, and is indicated, for example, in five stages. FIG. 3 shows a data structure of the table stored in the storage unit 130. Here, the deterioration levels increase in order from deterioration level A to deterioration level B, deterioration level C, deterioration level D, and deterioration level E. The deterioration level A is a state in which the SOH is 90% or more, the deterioration level B is a state in which the SOH is lower than 89% and 90% or more, the deterioration level C is a state in which the SOH is lower than 79% and 70% or more, the deterioration level D is a state in which the SOH is lower than 69% and 60% or more, and the deterioration level E is a state in which the SOH is lower than 59%. That is, the deterioration level A is the lowest deterioration level and indicates a state closest to the initial state. On the other hand, the deterioration level E is the highest deterioration level and indicates a state in which deterioration has progressed the most. It can be said that such deterioration level A indicates a state close to new, deterioration level B indicates a slightly deteriorated state, deterioration level C indicates a significantly deteriorated state, deterioration level D indicates a state before the end of its life, and deterioration level E indicates a state at the end of its life. Here, deterioration level D or E corresponds to a state in which an abnormality has occurred in the storage battery pack 100, and the notification of deterioration level D or E corresponds to information for notifying the abnormal state of the storage battery pack 100 (hereinafter referred to as a "storage battery pack abnormality notification"). The storage battery pack abnormality notification can also be called a notification of a recommendation to discard the storage battery pack.

[0029] Here, the number of discharges is defined as 1 discharge of 10Wh or more. The number of charges is defined as 1 charge of 50Wh or more. The average number of charges and discharges is defined as the average number of times per month. The conditions are Awh>Dwh, Bwh>Ewh, and C hours>F hours, with the transition occurring more easily (the degree of deterioration increasing) when the frequency of use is high. Return to Figure 2.

[0030] (3) Communication via short-range wireless communication systems As described above, communication is performed between the first communication unit 140 of the storage battery pack 100 and the first communication unit 310 of the information terminal device 300 using a short-range wireless communication system. Here, an overview of BLE will be described as an example of a short-range wireless communication system with reference to FIG. 4. FIG. 4 is a sequence diagram showing a communication procedure performed by the charging / discharging system 1000. The storage battery pack 100 periodically transmits an advertisement (S10, S12). When the information terminal device 300 receives the advertisement, it executes a scan (S14).

[0031] The information terminal device 300 transmits a connection request to the storage battery pack 100 (S16). The storage battery pack 100 transmits a connection response (S18). As a result, a connection between the storage battery pack 100 and the information terminal device 300 is established (S20). The information terminal device 300 transmits a read to the storage battery pack 100 (S22). The read is a request for the storage battery pack 100 to transmit information. The storage battery pack 100 transmits a read response to the information terminal device 300 (S24). The read response is information corresponding to the transmission request. The information terminal device 300 transmits a disconnection request to the storage battery pack 100 (S26). The storage battery pack 100 transmits a disconnection response to the information terminal device 300 (S28). As a result, the connection between the storage battery pack 100 and the information terminal device 300 is disconnected (S30). Return to FIG. 2.

[0032] (4) Display of information In order to explain the processing in the information terminal device 300, FIG. 5(a)-(b), FIG. 6(a)-(c), and FIG. 7(a)-(b) are also used here. FIG. 5(a)-(c) show a screen displayed on the display unit 340. FIG. 5(a) shows a screen displayed on the display unit 340 in the information terminal device 300 in which an application is installed, when the application is not running. A plurality of icons are displayed on the screen. The user of the information terminal device 300 selects an icon 600 by operating the operation unit 350 while looking at the screen displayed on the display unit 340 as shown in FIG. 5(a). An instruction to select the icon 600 by the user is output from the operation unit 350 to the control unit 320. When the control unit 320 receives the instruction to select, it starts the application stored in the storage unit 330. In the application, the first storage battery pack 100a to the third storage battery pack 100c are registered as communication targets by the short-range wireless communication system.

[0033] When the application is started, the control unit 320 controls the first communication unit 310 to execute communication with the registered first storage battery pack 100a as described above. At this time, the read is a request to transmit information (hereinafter referred to as "first information") from the first storage battery pack 100a. When the first communication unit 140 of the first storage battery pack 100a receives the read, the control unit 120 causes the first communication unit 140 to transmit the first information including various states determined by the determination unit 160 to the information terminal device 300. At this time, the first information may include a storage battery pack abnormality notification of the first storage battery pack 100a (hereinafter referred to as "first storage battery pack abnormality notification"). In addition, when the second communication unit 170 has received a charging / discharging device abnormality notification (hereinafter referred to as "first charging / discharging device abnormality notification") from the first charging / discharging device 200a, the control unit 120 also includes the first charging / discharging device abnormality notification in the first information. The first information corresponds to a read response. When the first communication unit 310 of the information terminal device 300 receives the first information from the first storage battery pack 100a, the acquisition unit 322 acquires the first information through direct wireless communication with the first storage battery pack 100a attached to the first charging / discharging device 200a. As described above, the first information may include a first storage battery pack abnormality notification and a first charging / discharging device abnormality notification.

[0034] The control unit 320 of the information terminal device 300 also executes such processing for the second storage battery pack 100b and the third storage battery pack 100c. As a result, the acquisition unit 322 acquires the second information from the second storage battery pack 100b by direct wireless communication with the second storage battery pack 100b attached to the second charging / discharging device 200b. The second information may include a second storage battery pack abnormality notification and a second charging / discharging device abnormality notification. The acquisition unit 322 also acquires the third information from the third storage battery pack 100c by direct wireless communication with the third storage battery pack 100c attached to the third charging / discharging device 200c. The third information may include a third storage battery pack abnormality notification and a third charging / discharging device abnormality notification. In this way, the application executed in the control unit 320 acquires information from the multiple storage battery packs 100 and the multiple charging / discharging devices 200.

[0035] The control unit 320 stores the first information to the third information acquired by the acquisition unit 322 in the storage unit 330. The storage unit 330 stores the information in association with the serial number of each storage battery pack 100 and the serial number of each charging / discharging device 200. The control unit 320 also outputs the first information to the third information acquired by the acquisition unit 322 to the second communication unit 360. The second communication unit 360 transmits the first information to the third information to the server device 500 via the network 400 in FIG. 1. The server device 500 stores the first information to the third information.

[0036] Furthermore, the control unit 320 displays the first information to the third information acquired by the acquisition unit 322 on the screen of the display unit 340 in a list. This corresponds to being able to display information on the first storage battery pack 100a to the third storage battery pack 100c and information on the first charging / discharging device 200a to the third charging / discharging device 200c connected thereto together. FIG. 5(b) shows a list display screen displayed on the display unit 340. On the list display screen, a first display area 610a, a second display area 610b, ..., and a seventh display area 610g are arranged in order from the top. The first display area 610a to the seventh display area 610g are collectively referred to as the display area 610, and the display area 610 has a rectangular shape that is long in the horizontal direction. The first display area 610a is an area for displaying the first information, the second display area 610b is an area for displaying the second information, and the third display area 610c is an area for displaying the third information. 1 and 2, the fourth information includes information from a fourth charge / discharge device 200d connected to the fourth battery pack 100d. The fifth to seventh display areas 610e to 610g are similar, and will not be described here.

[0037] In the first display region 610a, the serial number of the first storage battery pack 100a is displayed as a first serial number 612a, and the remaining battery charge of the first storage battery pack 100a is displayed as a first remaining battery charge 614a. In particular, the first remaining battery charge 614a is displayed by an indicator. The first remaining battery charge 614a may be displayed by a numerical value (0 to 100%). The display contents in the second display region 610b to the seventh display region 610g are similar to the display contents in the first display region 610a, and therefore description thereof will be omitted here.

[0038] As an example, an abnormality notification icon 620 is displayed next to the fifth serial number 612e in the fifth display area 610e. The abnormality notification icon 620 indicates that at least one of the fifth storage battery pack abnormality notification and the fifth charge / discharge device abnormality notification is included in the fifth information. By displaying such an abnormality notification icon 620, information on the charge / discharge device 200 to which the storage battery pack 100 is connected is also displayed in a list. If at least one of the first storage battery pack abnormality notification and the first charge / discharge device abnormality notification is included in the first information, the abnormality notification icon 620 is displayed next to the first serial number 612a in the first display area 610a. Also, if at least one of the second storage battery pack abnormality notification and the second charge / discharge device abnormality notification is included in the second information, the abnormality notification icon 620 is displayed next to the second serial number 612b in the second display area 610b. The same applies to the other display areas 610.

[0039] In FIG. 5(b), the first display area 610a to the seventh display area 610g are arranged in order from the top of the list screen. However, the control unit 320 may be able to rearrange the display areas 610 in the list display according to a preset pattern. This corresponds to being able to rearrange the first information to the seventh information according to a preset pattern. For example, each piece of information may be rearranged in ascending / descending order, or abnormal conditions may be sorted by type.

[0040] 6(a)-(c) show other screens displayed on the display unit 340. FIG. 6(a) shows the same list display screen as FIG. 5(b). When the user taps the first display area 610a, the operation unit 350 receives an instruction to select the first information. When the operation unit 350 receives an instruction to select the first information, the control unit 320 causes the display unit 340 to display a screen showing details of the first information (hereinafter referred to as a "detailed display screen"). FIG. 6(b) shows the detailed display screen of the first information.

[0041] On the detailed display screen, remaining battery power 630 is shown as a numerical value (0 to 100%). Below remaining battery power 630, SOH 632 is shown. SOH 632 indicates the maximum capacity state of the storage battery 110 of the first storage battery pack 100a. Below SOH 632, estimated usage time 634 when various loads are used with remaining battery power 630 is shown. Furthermore, an LED light button 636 is arranged at the bottom of the detailed display screen. The LED light button 636 will be described later.

[0042] Fig. 6(c) shows a screen for displaying details of the first information. This is a different type of screen for displaying details from Fig. 6(b). Battery remaining capacity 630, SOH 632, estimated usage time 634, and LED illumination button 636 are displayed in the same manner as in Fig. 6(b). A discard button 638 is added to the bottom of the screen for displaying details. The discard button 638 will be described later.

[0043] 5B, as described above, the abnormality notification icon 620 is displayed in the fifth display area 610e. When the user taps the fifth display area 610e, the operation unit 350 receives an instruction to select the fifth information. When the operation unit 350 receives an instruction to select the fifth information, the control unit 320 causes the display unit 340 to display a screen showing details of the fifth information for which the abnormality notification has been issued.

[0044] 7(a)-(b) show further screens displayed on the display unit 340. FIG. 7(a) shows a screen for displaying details of the fifth information, that is, a screen for displaying details of information for which an abnormality notification has been issued. The remaining battery level 630, the SOH 632, the estimated usage time 634, the LED light button 636, and the discard button 638 are displayed in the same manner as in FIG. 6(c). Here, the remaining battery level 630, the SOH 632, the estimated usage time 634, and the LED light button 636 may be displayed in the same manner as in FIG. 6(b). In the upper part of the detailed information screen, a storage battery pack abnormality notification message 640 and a charging / discharging device abnormality notification message 642 are arranged. The storage battery pack abnormality notification message 640 is a message displayed when the fifth information includes a fifth storage battery pack abnormality notification, and the charging / discharging device abnormality notification message 642 is a message displayed when the fifth information includes a fifth charging / discharging device abnormality notification. In other words, when the information from the battery pack 100 includes a battery pack abnormality notification, a battery pack abnormality notification message 640 is displayed, and when the information from the battery pack 100 includes a charge / discharge device abnormality notification, a charge / discharge device abnormality notification message 642 is displayed.

[0045] When the user wants to check the details of the battery pack abnormality notification message 640, the user taps the battery pack abnormality notification message 640, and the operation unit 350 accepts an instruction to select the fifth battery pack abnormality notification. When the operation unit 350 accepts an instruction to select the fifth battery pack abnormality notification, the control unit 320 causes the display unit 340 to display a screen showing the contents of the fifth battery pack abnormality notification (hereinafter, referred to as a "notification display screen"). FIG. 7(b) shows the notification display screen. The contents of the fifth battery pack abnormality notification are shown, for example, as "XXXXXX". Here, an abnormality code may be displayed, or the URL (Uniform Resource Locator) of the manufacturer of the battery pack 100 may be displayed. In FIG. 7(a), when the user taps the charge / discharge device abnormality notification message 642, a screen similar to that of FIG. 7(b) is displayed on the display unit 340. Return to FIG. 2.

[0046] The subject of the device, system, or method in the present disclosure includes a computer. The computer executes a program to realize the function of the subject of the device, system, or method in the present disclosure. The computer includes a processor that operates according to a program as a main hardware configuration. The type of the processor does not matter as long as it can realize the function by executing the program. The processor is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or an LSI (Large Scale Integration). The multiple electronic circuits may be integrated into one chip or may be provided on multiple chips. The multiple chips may be integrated into one device or may be provided on multiple devices. The program is recorded on a non-transitory recording medium such as a computer-readable ROM, an optical disk, or a hard disk drive. The program may be stored in the recording medium in advance, or may be supplied to the recording medium via a wide area communication network including the Internet.

[0047] The operation of the charging / discharging system 1000 configured as above will be described. FIG. 8 is a sequence diagram showing a display procedure by the charging / discharging system 1000. When the first charging / discharging device 200a detects an abnormality (S50), it transmits a first charging / discharging device abnormality notification to the first storage battery pack 100a (S52). The first storage battery pack 100a transmits first information including the first charging / discharging device abnormality notification to the information terminal device 300 (S54). The second storage battery pack 100b transmits second information to the information terminal device 300 (S56), and the third storage battery pack 100c transmits third information to the information terminal device 300 (S58). The information terminal device 300 displays a list of the first information to the third information (S60). The information terminal device 300 transmits the information to the server device 500 (S62). The server device 500 stores the information (S64).

[0048] According to this embodiment, direct wireless communication is performed with each of the multiple storage battery packs 100 to display information about each of the multiple storage battery packs 100 in a list, so that the information about each of the multiple storage battery packs 100 can be checked at once. Furthermore, because the information about each of the multiple storage battery packs 100 can be checked at once, the usability of the storage battery packs 100 can be improved. Furthermore, because the information about the multiple storage battery packs 100 is displayed in a list, various pieces of information can be checked on one screen.

[0049] Furthermore, when an abnormality occurs in the charging / discharging device 200, a charging / discharging device abnormality notification is received via the storage battery pack 100, so information about the charging / discharging device 200 can be obtained even if there is no direct connection to the charging / discharging device 200. Furthermore, since information about the charging / discharging device 200 can be obtained even if there is no direct connection to the charging / discharging device 200, the configuration of the charging / discharging device 200 can be prevented from becoming complicated. If there is a battery pack abnormality notification or a charging / discharging device abnormality notification in each of the multiple storage battery packs 100, they are displayed in a list, so that the usability of the storage battery packs 100 and the charging / discharging device 200 can be improved.

[0050] Moreover, since the first information and the second information in the list display can be rearranged according to a preset pattern, it is possible to improve the ease of use of the storage battery pack 100. Moreover, since the first information and the second information are stored in the server device 500 via the network 400, the first information and the second information can be managed by the server device 500.

[0051] An overview of one aspect of the present disclosure is as follows: An information terminal device (300) according to one aspect of the present disclosure includes an acquisition unit (322) that acquires first information from a first storage battery pack (100a) attached to a first charging / discharging device (200a) through direct wireless communication with the first storage battery pack (100a) and acquires second information from a second storage battery pack (100b) attached to a second charging / discharging device (200b) through direct wireless communication with the second storage battery pack (100b), and a control unit (320) that displays a list of the first information and the second information acquired by the acquisition unit (322) on a screen.

[0052] The control unit (320) may be capable of rearranging the first information and the second information in the list display according to a preset pattern.

[0053] The control unit (320) may store the first information and the second information acquired by the acquisition unit (322) in the server device (500) via the network (400).

[0054] Another aspect of the present disclosure is a charge / discharge system (1000). The charge / discharge system (1000) includes a first charge / discharge device (200a), a first storage battery pack (100a) attached to the first charge / discharge device (200a), a second charge / discharge device (200b), a second storage battery pack (100b) attached to the second charge / discharge device (200b), and an information terminal device (300) capable of performing direct wireless communication with the first storage battery pack (100a) and the second storage battery pack (100b). The information terminal device (300) includes an acquisition unit (322) that acquires first information from the first storage battery pack (100a) through direct wireless communication with the first storage battery pack (100a) and acquires second information from the second storage battery pack (100b) through direct wireless communication with the second storage battery pack (100b), and a control unit (320) that displays the first information and second information acquired by the acquisition unit (322) in a list on a screen. The first information acquired by the acquisition unit (322) includes a first battery pack abnormality notification for notifying an abnormal state of the first battery pack (100a) when an abnormality occurs in the first battery pack (100a), and a first charging / discharging device abnormality notification transmitted from the first charging / discharging device (200a) via the first battery pack (100a) when an abnormality occurs in the first charging / discharging device (200a) and for notifying an abnormal state of the first charging / discharging device (200a); The second information acquired by the acquisition unit (322) includes a second battery pack abnormality notification for notifying the user of an abnormal state of the second battery pack (100b) when an abnormality occurs in the second battery pack (100b), and a second charging / discharging device abnormality notification transmitted from the second charging / discharging device (200b) via the second battery pack (100b) when an abnormality occurs in the second charging / discharging device (200b) and for notifying the user of the abnormal state of the second charging / discharging device (200b).

[0055] Example 2 Next, a second embodiment will be described. As in the first embodiment, the second embodiment relates to a charging / discharging system 1000 that enables charging / discharging of the storage battery pack 100 by connecting the storage battery pack 100 to the charging / discharging device 200. In the first embodiment, information on each of the multiple storage battery packs 100 is displayed in a list on the information terminal device 300. At that time, it is desirable to immediately grasp the correspondence between the information displayed on the information terminal device 300 and the actual storage battery pack 100. In order to deal with this, when a list is displayed on the information terminal device 300 according to the second embodiment, when a user taps an icon of a specific storage battery pack 100, the information terminal device 300 transmits call information to the storage battery pack 100. When the storage battery pack 100 receives the call information, it turns on an LED. The charging / discharging system 100 according to the second embodiment is of the same type as that shown in FIG. 1 and FIG. 2. Here, the difference from the first embodiment will be mainly described.

[0056] In order to explain the second embodiment, Fig. 9(a)-(b) will also be used. Fig. 9(a)-(b) shows the configuration of the charging / discharging system 1000. Fig. 9(a) shows the same list display screen as Fig. 5(b). In each display area 610 in the list display screen, a battery pack icon 650 is displayed. When a user wants to find the first battery pack 100a among the multiple battery packs 100 that are actually arranged, when the user taps the battery pack icon 650 in the first display area 610a, the operation unit 350 accepts an instruction to select the first battery pack 100a. Here, even when the LED lighting button 636 in Fig. 6(b)-(c) is tapped, the operation unit 350 accepts an instruction to select the first battery pack 100a.

[0057] When the operation unit 350 receives an instruction to select the first storage battery pack 100a, the control unit 320 generates information for calling the first storage battery pack 100a (hereinafter referred to as "first call information"). The first call information includes information for identifying the first storage battery pack 100a and an instruction to call. The control unit 320 outputs the first call information to the first communication unit 310. When the first communication unit 310 receives the first call information from the control unit 320, it transmits the first call information to the first storage battery pack 100a.

[0058] FIG. 9B shows the arrangement of a plurality of storage battery packs 100. Here, the first storage battery pack 100a to the seventh storage battery pack 100g are arranged. The first communication unit 140 in the first storage battery pack 100a receives the first call information from the information terminal device 300. When the first communication unit 140 receives the first call information, the control unit 120 performs a process according to the call, for example, turns on the notification unit 150 (light-emitting unit). That is, when the reception unit 240 receives an instruction to select the first storage battery pack 100a, the output unit 324 of the information terminal device 300 outputs the first call information to the first communication unit 310, thereby causing the first call information to be transmitted to the first storage battery pack 100a by direct wireless communication with the first storage battery pack 100a.

[0059] On the other hand, when the user wants to search for the second storage battery pack 100b, the user taps the storage battery pack icon 650 in the second display area 610b in FIG. 9(a), and the operation unit 350 receives an instruction to select the second storage battery pack 100b. When the operation unit 350 receives an instruction to select the second storage battery pack 100b, the control unit 320 generates information for calling the second storage battery pack 100b (hereinafter referred to as "second call information"), and the first communication unit 310 transmits the second call information to the second storage battery pack 100b. The first communication unit 140 in the second storage battery pack 100b receives the second call information from the information terminal device 300. When the first communication unit 140 receives the second call information, the control unit 120 performs a process according to the call, for example, turns on the notification unit 150 (light-emitting unit). A similar process is performed when searching for another storage battery pack 100.

[0060] The operation of the charging / discharging system 1000 configured as above will be described. Fig. 10 is a sequence diagram showing the lighting procedure by the charging / discharging system 1000. The information terminal device 300 accepts the selection of the first storage battery pack 100a (S100). The information terminal device 300 transmits first call information to the first storage battery pack 100a (S102). The first storage battery pack 100a turns on when it receives the first call information (S104). The information terminal device 300 accepts the selection of the second storage battery pack 100b (S106). The information terminal device 300 transmits second call information to the second storage battery pack 100b (S108). The second storage battery pack 100b turns on when it receives the second call information (S110).

[0061] According to this embodiment, when an instruction to select a storage battery pack 100 is received, call information is transmitted to the storage battery pack 100, and the storage battery pack 100 executes processing according to the call information, so that it is possible to immediately grasp the correspondence between the information displayed on the information terminal device 300 and the actual storage battery pack 100. In addition, the storage battery pack 100 lights up when it receives the call information, so that the storage battery pack 100 can be quickly found.

[0062] An overview of one aspect of the present disclosure is as follows: The device may further include an operation unit (350) that receives an instruction to select the first storage battery pack (100a) from a screen displayed as a list by the control unit (320), and an output unit (324) that outputs first call information for calling the first storage battery pack (100a) when the operation unit (350) receives the instruction to select the first storage battery pack (100a), thereby causing the first call information to be transmitted to the first storage battery pack (100a) by direct wireless communication with the first storage battery pack (100a). The operation unit (350) may receive an instruction to select the second storage battery pack (100b) from the screen displayed as a list by the control unit (320), and when the operation unit (350) receives the instruction to select the second storage battery pack (100b), the output unit (324) may output second call information for calling the second storage battery pack (100b), thereby causing the second call information to be transmitted to the second storage battery pack (100b) by direct wireless communication with the second storage battery pack (100b), and when the first storage battery pack (100a) receives the first call information, the first storage battery pack (100a) may perform processing in response to the call, and when the second storage battery pack (100b) receives the second call information, the output unit (324) may cause the second storage battery pack (100b) to transmit the second call information by direct wireless communication with the second storage battery pack (100b).

[0063] The first storage battery pack (100a) may turn on the light-emitting section (150) when receiving the first call information, and the second storage battery pack (100b) may turn on the light-emitting section (150) when receiving the second call information.

[0064] Example 3 Next, a third embodiment will be described. The third embodiment relates to a charging / discharging system 1000 that enables charging / discharging of the battery pack 100 by connecting the battery pack 100 to the charging / discharging device 200, as in the past. Even if some error occurs when the battery pack 100 is used, the battery pack 100 may be left unattended without the user recognizing the error. Such a situation may also occur in the charging / discharging device 200. Furthermore, if the battery pack 100 is left unattended with a low remaining battery level, the battery pack 100 may be over-discharged and become unusable. The battery pack 100 in this embodiment transmits information to the charging / discharging device 200 when an abnormality occurs or the remaining battery level is low. When the information terminal device 300 receives information from the battery pack 100, it executes a push notification if the information satisfies the push notification condition even if the application has not been started. The charging / discharging system 100 according to the third embodiment is of the same type as that shown in FIG. 1 and FIG. 2. Here, the differences from the past will be mainly described. The charge / discharge system 1000 according to the third embodiment may be called a processing system.

[0065] The application of the information terminal device 300 assigns a management code to the storage battery pack 100 to be managed by the application in advance. The management code is stored in the storage unit 330 of the information terminal device 300 and also in the storage unit 130 of the storage battery pack 100. When the management code stored in the storage unit 330 is called an "application management code", the management code stored in the storage unit 130 is called a "storage battery pack management code". At this time, the storage unit 330 also stores the serial number of the storage battery pack 100 to which the storage battery pack management code is assigned, in association with the application management code. Below, the following cases will be described in the order of (i) the case where the management codes match and the push notification condition is satisfied, (ii) the case where the management codes match but the push notification condition is not satisfied, and (iii) the case where the serial number is not registered. The push notification conditions will be described in detail later.

[0066] (i) If the management code matches and the push notification conditions are met 11(a)-(c) are sequence diagrams showing communication procedures performed by the charging / discharging system 1000. In FIG. 11(a), the control unit 320 of the information terminal device 300 has not yet started an application (S200). The first communication unit 140 of the storage battery pack 100 periodically transmits an advertisement (S202, S204). The advertisement is a broadcast signal and includes the serial number of the storage battery pack 100. The serial number is represented by, for example, 12 bytes.

[0067] The first communication unit 310 of the information terminal device 300 receives the advertisement. The control unit 320 extracts the serial number included in the advertisement and performs administrator determination based on the extracted serial number (S206). Specifically, if the application management code associated with the serial number is stored in the storage unit 330 and the serial number is not a push-notified serial number, the control unit 320 decides to start scanning. The push-notified serial number will be described later, but the push-notified serial number is stored in the storage unit 330.

[0068] When the control unit 320 decides to start scanning, the information terminal device 300 executes a scan (S208). The control unit 320 of the information terminal device 300 transmits a connection request from the first communication unit 310 to the storage battery pack 100 (S210). When the first communication unit 140 of the storage battery pack 100 receives the connection request, the control unit 120 transmits a connection response from the first communication unit 140 to the information terminal device 300 (S212). When the first communication unit 310 of the information terminal device 300 receives the connection response, a connection between the storage battery pack 100 and the information terminal device 300 is established (S214).

[0069] In a state where a connection with the storage battery pack 100 is established, the control unit 320 of the information terminal device 300 transmits a read from the first communication unit 310 to the storage battery pack 100 (S216). As described above, the read is a request to transmit information to the storage battery pack 100. When the first communication unit 140 of the storage battery pack 100 receives the read, the control unit 120 transmits a read response from the first communication unit 140 to the information terminal device 300 (S218). As described above, the read response is information corresponding to the transmission request. As a result, even if the application has not been started, the acquisition unit 322 acquires information from the storage battery pack 100 as a response to the transmission request by direct wireless communication with the storage battery pack 100. The information includes a storage battery pack management code. In addition, when the storage battery pack 100 is attached to the charging / discharging device 200, the information may also include a charging / discharging device abnormality notification transmitted from the charging / discharging device 200 via the storage battery pack 100.

[0070] The control unit 320 executes a push notification determination for the information acquired by the acquisition unit 322 (S220). Items included in the push notification conditions are determined as follows: (A) to (F). (A) The application is not running. (B) The application management code and the battery pack management code are the same. (C) The battery level is below a threshold, e.g. 10%. (D) The operating status, which indicates charging, discharging, or stopping, indicates stopping. (E) Battery pack abnormality notification is included. (F) Notification of abnormality in charging / discharging device is included

[0071] The control unit 320 determines that the push notification determination is satisfied when a combination of (C) and (D) or (E) or (F) is satisfied under a situation where (A) and (B) are satisfied. The control unit 320 executes the push notification when it is determined that the push notification conditions are satisfied.

[0072] 12(a)-(b) show screens displayed on the display unit 340. FIG. 12(a) shows a push notification screen when the information includes a battery pack abnormality notification. A push notification window 660 is displayed on the display unit 340, and the push notification window 660 shows a message saying "An abnormality has occurred in the battery pack with ID001. Please check the battery pack." This type of display is made, for example, when a user carrying the information terminal device 300 passes near the battery pack 100 while an abnormality has occurred in the battery pack 100. A similar display is made when the information includes a charge / discharge device abnormality notification.

[0073] Fig. 12(b) shows a push notification screen when the remaining battery level included in the information is below a threshold value. A push notification window 660 is displayed on the display unit 340, and the push notification window 660 displays a message saying "The remaining battery level of ID001 is below 10%. Please charge." Such a display is made, for example, when the storage battery pack 100 has been stored for a long time in a warehouse or the like. Return to Fig. 11(a).

[0074] When the control unit 120 executes the push notification, the memory unit 130 stores the serial number of the storage battery pack 100 as a push-notified serial number (S222). The push-notified serial number can be considered as identification information for identifying the storage battery pack 100. For example, the memory unit 130 can store up to 100 push-notified serial numbers. The control unit 320 of the information terminal device 300 transmits a disconnection request from the first communication unit 310 to the storage battery pack 100 (S224). The control unit 120 of the storage battery pack 100 transmits a disconnection response from the first communication unit 140 to the information terminal device 300 (S226). As a result, the connection between the storage battery pack 100 and the information terminal device 300 is disconnected (S228).

[0075] FIG. 11(b) shows a pattern different from that of FIG. 11(a). Steps 250 to 254 are the same as steps 200 to 204 in FIG. 11(a). The control unit 320 extracts the serial number included in the advertisement and performs administrator determination based on the extracted serial number (S256). Specifically, even if the application management code associated with the serial number is stored in the storage unit 330, if the serial number is a push-notified serial number, the control unit 320 decides not to start scanning and ends the process. In other words, if the serial number included in the newly received advertisement matches the push-notified serial number stored in the storage unit 330, the control unit 320 does not establish a connection with the storage battery pack 100. Steps 258 to 262 are the same as steps 252 to 256.

[0076] Fig. 11(c) shows a pattern different from Fig. 11(a)-(b). In Fig. 11(c), the control unit 320 of the information terminal device 300 starts an application (S300). When the control unit 320 starts the application, it resets the push notified serial number stored in the storage unit 330 (S302). The subsequent steps 304 to 324 are the same as steps 10 to 30 in Fig. 4.

[0077] (ii) If the management code matches but the push notification conditions are not met FIG. 13(a)-(c) are sequence diagrams showing another communication procedure by the charging / discharging system 1000. Steps 350 to 368 in FIG. 13(a) are the same as steps 200 to 218 in FIG. 11(a). The control unit 320 executes a push notification determination for the information acquired by the acquisition unit 322 (S270). The control unit 320 determines that the push notification determination is not satisfied when (A) and (B) are not satisfied, or when the combination of (C) and (D) and (E) and (F) are not satisfied. The control unit 320 does not execute a push notification when it is determined that the push notification condition is not satisfied. Therefore, the storage unit 330 does not store the serial number of the storage battery pack 100 as a push-notified serial number. Steps 372 to 376 are the same as steps 224 to 228 in FIG. 11(a).

[0078] FIG. 13(b) shows the process when the same information is received from the same storage battery pack 100, following FIG. 13(a). That is, the push notification determination is not satisfied again. Therefore, steps 400 to 426 are the same as steps 350 to 376 in FIG. 13(a). FIG. 13(c) shows the process when an application is started, following FIG. 13(b). Therefore, steps 450 to 474 in FIG. 13(c) are the same as steps 300 to 324 in FIG. 11(c).

[0079] (iii) If the serial number is not registered 14(a)-(b) are sequence diagrams showing another communication procedure by the charging / discharging system 1000. Steps 500 to 504 in FIG. 14(a) are the same as steps 200 to 204 in FIG. 11(a). The first communication unit 310 of the information terminal device 300 receives an advertisement. The control unit 320 extracts the serial number included in the advertisement and performs administrator determination based on the extracted serial number (S506). If the application management code associated with the serial number is not stored in the storage unit 330, the control unit 320 decides not to start scanning and ends the process. Steps 508 to 512 are the same as steps 502 to 506.

[0080] According to this embodiment, a push notification is executed when the acquired information satisfies the push notification condition, and a push notification is not executed when the acquired information does not satisfy the push notification condition, so that highly necessary information can be push-notified. In addition, since a push notification is executed even if an application is not started, highly urgent information can be notified to a user. In addition, since the push notification condition is at least one of the remaining capacity of the storage battery pack 100 being equal to or less than a threshold value, the operation state of the storage battery pack 100 indicating a stop, and the abnormal state of the storage battery pack 100 indicating an abnormality, highly urgent information can be notified to a user. In addition, since the push notification condition also includes the abnormal state of the charging / discharging device 200 indicating an abnormality, highly urgent information related to the charging / discharging device 200 can be notified to a user.

[0081] Furthermore, since the information is acquired after a broadcast signal from the storage battery pack 100 is received and a connection with the storage battery pack 100 is established, and then a request to transmit information is transmitted, the BLE communication procedure can be used to acquire the information. Furthermore, when a push notification is executed, the serial number of the storage battery pack 100 is stored as a push-notified serial number, and if the serial number included in a newly received advertisement matches the push-notified serial number, the push notification is not executed, so that unnecessary push notifications can be avoided. Furthermore, since unnecessary push notifications are avoided, battery consumption of the information terminal device 300 can be reduced.

[0082] An overview of one aspect of the present disclosure is as follows. An information terminal device (300) of one aspect of the present disclosure includes an acquisition unit (322) that acquires information from the storage battery pack (100) by direct wireless communication with the storage battery pack (100), and a control unit (320) that executes a push notification when the information acquired by the acquisition unit (322) satisfies a push notification condition. The control unit (320) does not execute a push notification when the information acquired by the acquisition unit (322) does not satisfy the push notification condition.

[0083] The push notification condition in the control unit (320) may be at least one of the following: the remaining capacity of the storage battery pack (100) included in the information is equal to or less than a threshold value; the operating status of the storage battery pack (100) included in the information indicates stopped; and the abnormal status of the storage battery pack (100) included in the information indicates that there is an abnormality.

[0084] The storage battery pack (100) is attached to the charging / discharging device (200), and the information acquired by the acquisition unit (322) includes an abnormal state of the charging / discharging device (200) transmitted from the charging / discharging device (200) via the storage battery pack (100), and the push notification condition in the control unit (320) may also include an indication that the abnormal state of the charging / discharging device (200) included in the information is an abnormal state.

[0085] After receiving a broadcast signal from the storage battery pack (100), the information terminal device (300) transmits an information transmission request to the storage battery pack (100) when a connection with the storage battery pack (100) is established, and the acquisition unit (322) may acquire the information received by the information terminal device (300) from the storage battery pack (100) in response to the transmission request.

[0086] The device may further include a storage unit (330) that stores identification information for identifying the storage battery pack (100) when the control unit (320) executes a push notification. When the identification information included in the newly received broadcast signal matches the identification information stored in the storage unit (330), the control unit (320) does not establish a connection with the storage battery pack (100).

[0087] Yet another aspect of the present disclosure is a processing system. The processing system includes a storage battery pack (100) and an information terminal device (300) capable of performing direct wireless communication with the storage battery pack (100). The information terminal device (300) includes an acquisition unit (322) that acquires information from the storage battery pack (100) through direct wireless communication with the storage battery pack (100), and a control unit (320) that executes a push notification when the information acquired by the acquisition unit (322) satisfies a push notification condition. The control unit (320) does not execute a push notification when the information acquired by the acquisition unit (322) does not satisfy the push notification condition.

[0088] Example 4 Next, a fourth embodiment will be described. The fourth embodiment relates to a charging / discharging system 1000 that enables charging / discharging of the battery pack 100 by connecting the battery pack 100 to the charging / discharging device 200, as in the past. When the purpose is to provide a function that can be used only by a specific user, it is necessary to provide a dedicated application to the specific user. This may result in a complicated specification for the user. In this embodiment, a management code is set for the battery pack 100 from an application of the information terminal device 300, thereby enabling the expansion of the control function to the battery pack 100. The management code is set in advance in the third embodiment, but in the fourth embodiment, it is used to expand the control function. The charging / discharging system 1000 according to the fourth embodiment is of the same type as that shown in FIG. 1 and FIG. 2. Here, the differences from the previous embodiments will be mainly described. The charging / discharging system 1000 according to the fourth embodiment may be called a processing system.

[0089] When a management code is not set in the battery pack 100, the control unit 320 can issue a management code to the battery pack 100. To be more specific, when a management code is not set for the battery pack 100, the application executed in the control unit 320 of the information terminal device 300 automatically issues a management code when the application registers a management code for the battery pack 100. At that time, the application acquires a serial number from the battery pack 100 via the first communication unit 310. The application stores the issued management code in the storage unit 330 as an application management code while associating it with the serial number. In addition, the application transmits the management code to the battery pack 100 via the first communication unit 310. The control unit 120 of the battery pack 100 stores the received management code as a battery management code.

[0090] 15 shows the data structure of a table stored in storage unit 330. The table shows the presence or absence of an application management code, the presence or absence of a battery pack management code, and the corresponding controllable functions. Here, a case where the application management code and the battery pack management code are both "present" and match is called a first state. On the other hand, a case where the application management code and the battery pack management code are both "present" but do not match, or a case where at least one of the application management code and the battery pack management code is "absent" is called a second state.

[0091] Additionally, "BLE connection," "display of remaining capacity, maximum capacity, and abnormality in the application" are referred to as first processing. Furthermore, "discharge instruction / cancellation when discarding," "notification of low remaining capacity, abnormality notification (push notification when application is not running)," and "deletion of management code of storage battery pack 100 by application" are referred to as second processing. In the first state, control unit 320 controls so that the first process and the second process are executable. In the second state, control unit 320 controls so that the first process on storage battery pack 100 is executable, while controlling so that the second process on storage battery pack 100 is not executable. Return to FIG. 2.

[0092] Here, the "discharge instruction at the time of disposal" will be described. When the "discharge instruction at the time of disposal" is controlled to be executable, the display unit 340 can display the detailed display screen of FIG. 6(c). When the Discard button 638 on the detailed display screen is tapped, the operation unit 350 accepts the discharge instruction at the time of disposal. The control unit 320 causes the first communication unit 310 to transmit the discharge instruction at the time of disposal to the storage battery pack 100.

[0093] The first communication unit 140 of the storage battery pack 100 receives a discharge instruction at the time of disposal from the information terminal device 300. The control unit 120 causes the notification unit 150 to display a notification to notify the start of the disposal discharge. For example, the notification unit 150 causes all of the LEDs to blink. The second communication unit 170 transmits the discharge instruction at the time of disposal to the charging / discharging device 200. The communication unit 230 of the charging / discharging device 200 receives the discharge instruction at the time of disposal. In response to this, the reception unit 240 receives the discharge instruction at the time of disposal. When the reception unit 240 receives the discharge instruction at the time of disposal, the charging / discharging circuit 210 uses the discharger 280 that reduces the capacity of the storage battery 110 to discharge the storage battery pack 100 to a second level lower than the first level. The discharger 280 is, for example, a resistor. The second level is defined as, for example, a value equal to or greater than the remaining battery charge at which the first communication unit 140 of the storage battery pack 100 can transmit the end of discharging to the information terminal device 300 and the control unit 120 can be driven. At that time, the control unit 220 uses the cooling fan 270, which is normally used to cool the charge / discharge circuit 210, to cool the discharger 280.

[0094] The charge / discharge circuit 210 ends the discharge when the remaining battery charge of the storage battery 110 reaches a second level. When the control unit 120 of the storage battery pack 100 detects the end of the discharge, it causes the notification unit 150 to display a notification to notify the end of the discharge. For example, the notification unit 150 turns off all of the multiple LEDs. The control unit 120 causes the notification of the end of the discharge to be transmitted to the information terminal device 300 via the first communication unit 140. The notification of the end of the discharge corresponds to a notification that preparation for disposal is complete.

[0095] The first communication unit 310 of the information terminal device 300 receives a notification of the end of discharging from the storage battery pack 100. The control unit 320, for example, causes the display unit 340 to display guidance for disposing of the storage battery pack 100. The control unit 320 also transmits the notification of the end of discharging to the server device 500 via the second communication unit 360. Upon receiving the notification of the end of discharging, the server device 500 registers the storage battery pack 100 that can be disposed of.

[0096] Furthermore, the control unit 320 can delete a management code for the storage battery pack 100 that has already been set. When the storage battery pack management code acquired from the storage battery pack 100 via the first communication unit 310 matches the application management code stored in the memory unit 330, the application executed in the control unit 320 of the information terminal device 300 decides to delete the management code. When it is decided to delete the management code, the application deletes the application management code stored in the memory unit 330. In addition, the application transmits an instruction to delete the battery pack management code to the first communication unit 140 via the first communication unit 310. When the control unit 120 of the storage battery pack 100 receives the instruction to delete the battery pack management code via the first communication unit 140, it deletes the battery pack management code stored in the memory unit 130.

[0097] According to this embodiment, since executable processes are changed according to the battery pack management code and the application management code, function extension can be easily performed. Furthermore, when the battery pack management code and the application management code match, the second process can be executed in addition to the first process, so function extension can be easily performed. Furthermore, even if the battery pack management code and the application management code do not match, the first process can be executed, so that necessary processes can be executed. Furthermore, since the first process is a process for displaying the remaining capacity of the battery pack 100 on the screen, and the second process is a process for discharging the battery pack 100 for disposal, the remaining capacity of the battery pack 100 can be displayed on the screen regardless of the management code. Furthermore, since a management code can be issued, the management code can be set as necessary.

[0098] An overview of one aspect of the present disclosure is as follows. Another aspect of the present disclosure is also an information terminal device (300). This device includes an acquisition unit (322) that acquires information from the storage battery pack (100) by direct wireless communication with the storage battery pack (100), a storage unit (330) that stores a management code that has already been issued, and a control unit (320) that controls a first process and a second process for the storage battery pack (100) to be executable in a first state in which the management code of the storage battery pack (100) corresponding to the information acquired by the acquisition unit (322) matches the management code stored in the storage unit (330). In a second state different from the first state, the control unit (320) controls the first process for the storage battery pack (100) to be executable, while controlling the second process for the storage battery pack (100) to be inexecutable.

[0099] The first process may be a process of displaying the remaining capacity of the battery pack (100) on a screen, and the second process may be a process of discharging the battery pack (100) for disposal.

[0100] If a management code is not set in the battery pack (100), the control unit (320) may issue a management code to the battery pack (100), and the memory unit (330) may store the management code issued by the control unit (320).

[0101] Yet another aspect of the present disclosure is also a processing system. The processing system includes a storage battery pack (100) and an information terminal device (300) capable of performing direct wireless communication with the storage battery pack (100). The information terminal device (300) includes an acquisition unit (322) that acquires information from the storage battery pack (100) through direct wireless communication with the storage battery pack (100), a storage unit (330) that stores a management code that has already been issued, and a control unit (320) that controls a first process and a second process for the storage battery pack (100) to be executable in a first state in which the management code of the storage battery pack (100) corresponding to the information acquired by the acquisition unit (322) matches the management code stored in the storage unit (330). In a second state different from the first state, the control unit (320) controls the first process for the storage battery pack (100) to be executable, while controlling the second process for the storage battery pack (100) to be inexecutable.

[0102] The present disclosure has been described above based on the embodiments. These embodiments are merely illustrative, and it will be understood by those skilled in the art that various modifications are possible in the combination of each component or each treatment process, and that such modifications are also within the scope of the present disclosure.
