FIG. 3 is a sequence diagram showing an example of a flow of processing related to acquisition and management of electric power information by the charging information management system 100 of the present embodiment. Here, it is assumed that the user charges the battery 200 by using an application installed in the terminal device 500 in advance. Hereinafter, this application is referred to as a "charging application". The charging application is executed by the control unit 550 according to the activation operation of the user.

First, the user operates the terminal device 500 to activate the charging application. For example, the charging application displays the charging application screen as shown in FIG. 4 on the display unit 530 of the terminal device 500. For example, on the charging application screen, buttons B1 to B4 are arranged as an operation interface according to the procedure for performing charging. As a first step, the user performs an operation of acquiring the identification information of the battery 200 and transmitting it to the charging information management device 600. For example, the user presses the button B1 to image the two-dimensional code attached to the battery 200. In response to this operation, the charging app executes a photography function. The user inputs the shutter operation by adjusting the direction and distance so that the two-dimensional code displayed on the battery 200 is included in the imaging range. In response to this input operation, the image pickup unit 540 generates image data in which the two-dimensional code of the battery 200 is captured (step S101).

Subsequently, the identification information acquisition unit 551 recognizes the two-dimensional code in the image by performing image recognition processing on the image data generated by the image pickup unit 540, and decodes the recognized two-dimensional code to decode the battery 200. (Step S102). The identification information acquisition unit 551 waits for a transmission instruction in a state in which the acquired identification information of the battery 200 can be transmitted to the charging information management device 600. For example, when the identification information of the battery 200 is transmitted in the form of an e-mail, the identification information acquisition unit 551 generates an e-mail data containing the identification information of the battery 200 and instructs the transmission of the e-mail. Wait for input. For example, the identification information acquisition unit 551 waits for the input of the operation pressed by the button B2. The identification information acquisition unit 551 transmits the identification information of the battery 200 to the charging information management device 600 in response to the input of the transmission instruction (step S103).

Subsequently, the terminal device 500 acquires the identification information of the charger 300 in the same flow as the identification information of the battery 200 (steps S104 and S105), and transmits the acquired identification information of the charger 300 to the charging information management device 600. (Step S106). In FIG. 4, the button B3 receives an input of an operation instructing the execution of the photography function for the two-dimensional code of the charger 300, and the button B4 is a charging information management device for the identification information of the charger 300. It accepts the input of the operation instructing the transmission to the 600. After the transmission of the identification information of the battery 200 and the charger 300 is completed, the user subsequently connects the battery 200 to the charger 300. In response to this, the charger 300 starts charging the battery 200 (step S107).

On the other hand, in the terminal device 500, when the transmission of the identification information of the battery 200 and the charger 300 is completed, the power information acquisition unit 552 acquires the power information from the power meter 400 and the charge information management device of the acquired power information. The transmission to the 600 is periodically and repeatedly executed (step S108).

On the other hand, in the charging information management device 600, the information management unit 632 associates the power information received from the terminal device 500 with the identification information of the identification information of the battery 200 and the charger 300 (step S109). Specifically, the information management unit 632 determines the battery 200 and the charging based on the reception timing of the identification information of the battery 200 and the charger 300 and the timing when the charging of the battery 200 is started, which is specified by the power information. The identification information of the device 300 and the power information are associated with each other. Hereinafter, a method in which the information management unit 632 associates the identification information of the battery 200 and the charger 300 with the power information will be described in detail.

FIG. 5 is a flowchart showing an example of a flow of a process (association process) in which the information management unit 632 associates the identification information of the battery 200 and the charger 300 with the electric power information. Further, FIG. 6 is a diagram showing an example of the identification information and the electric power information of the battery 200 and the charger 300, and FIG. 7 is a diagram in which the identification information and the electric power information of the battery 200 and the charger 300 correspond to each other by the association processing. It is a figure which shows an example of the attached information (hereinafter referred to as "charging information"). Here, the flow of the association processing will be described with reference to FIGS. 6 and 7 as appropriate.

First, the information acquisition unit 631 records the identification information of the battery 200 received from the terminal device 500 in step S103 of FIG. 3 in the battery information table T1 shown in FIG. 6 (step S201). For example, the battery information table T1 may be created in advance in the storage unit 620, or may be created when the identification information of the battery 200 does not exist at the timing when it is received. The battery information table T1 is composed of one or more records having reception time and battery ID values. The value of the reception time represents the time when the identification information of the battery 200 is received in the charging information management device 600, and the value of the battery ID represents the identification information of the battery 200. Here, assuming a case where the battery information table T1 is created at the timing when the identification information of the battery 200 is received, the battery information table T1 having one record is illustrated.

Subsequently, the information acquisition unit 631 records the identification information of the charger 300 received from the terminal device 500 in step S106 in the charger information table T2 shown in FIG. 6, similarly to the identification information of the battery 200 (step S202). ). The charger information table T2 is composed of one or more records having each value of the reception time and the charger ID. The value of the reception time represents the time when the identification information of the charger 300 is received in the charging information management device 600, and the value of the charger ID represents the identification information of the charger 300. Similar to the battery information table T1, here, assuming that the charger information table T2 is created at the timing when the identification information of the charger 300 is received, the charger information table T2 having one record is exemplified. ing.

Subsequently, the information acquisition unit 631 receives the power information from the terminal device 500 (step S203), and records the received power information in the power information table T3 shown in FIG. 6 (step S204). The power information table T3 is composed of one or more records having each value of reception time and cumulative power consumption. The value of the reception time represents the time when the power information related to the charging of the battery 200 is received in the charge information management device 600, and the value of the cumulative power consumption is the cumulative value of the power supply to the connected device by the power meter 400. Represents. Cumulative power consumption is an example of power information.

The electric power information may include at least information that enables acquisition of the value of the electric energy required for charging the battery 200. For example, the power information may be information indicating an instantaneous value of the used power instead of the cumulative electric energy amount, or information indicating an instantaneous value of the voltage and the current applied to the connected device by the wattmeter 400. It may be used, and a part or all of this information may be included. In addition to such information, the power information may include other information regarding the charging of the battery 200.

Subsequently, the information management unit 632 refers to the power information table and determines whether or not the time when charging of the battery 200 is started (hereinafter referred to as “charging start time”) can be specified (step S205). For example, in the example of the power information table T3 of FIG. 6, since the cumulative power consumption does not change until 10:04 on October 16, 2020, the charging start time cannot be specified. In this case, the information management unit 632 returns the process to step S203, and repeatedly receives and records the power information. In the following, since the time of October 16, 2020 is exemplified as the charging start time and the receiving time, the description of the date is omitted.

On the other hand, in the example of the power information table T3 of FIG. 6, at 10:05, since the cumulative power consumption has increased more than before, it can be detected that the charging of the battery 200 has started. .. In this case, for example, the information management unit 632 can specify 10:04 or 10:05 as the charging start time point. When the information management unit 632 determines in step S205 that the charging start time can be specified, it determines whether or not there is identification information (hereinafter referred to as "target identification information") to be associated with the received power information. (Step S206).

For example, the information management unit 632 refers to the battery information table T1 and the charger information table T2, and identifies that the information is received within a predetermined time before and / or after the charging start time (hereinafter referred to as “correspondence period”). Determine if there is information. For example, in the example of FIG. 6, when 10:05 is specified as the charging start time and 5 minutes before the charging start time is set as the corresponding period, the battery ID value “MPP01” and the charger ID value “ BTX01 ”is determined to be the target identification information. On the other hand, if the charging start time remains the same and one minute before the charging start time is set as the corresponding period, it is determined that there is no target identification information.

If it is determined in step S206 that there is no target identification information, the information management unit 632 does not associate the identification information of the battery 200 and the charger 300 with the power information, and the notification unit 640 notifies the user to that effect. (Step S210), and the association processing is terminated. On the other hand, when it is determined in step S206 that the target identification information is present, the information management unit 632 determines whether or not the target identification information includes the identification information of the plurality of batteries 200 (step S207). Here, when it is determined that the target identification information includes the identification information of the plurality of batteries 200, the information management unit 632 does not associate the identification information of the battery 200 and the charger 300 with the power information, and the information management unit 632 does not associate the identification information with the power information. The notification unit 640 notifies the user to that effect (step S210), and the association process ends.

On the other hand, when it is determined in step S207 that the target identification information includes only the identification information of the battery 200 of 1 or less, the information management unit 632 has the identification information of the plurality of chargers 300 in the target identification information. Whether or not it is determined (step S208). Here, when it is determined that the target identification information includes the identification information of the plurality of batteries 200, the information management unit 632 does not associate the identification information of the battery 200 and the charger 300 with the power information, and the information management unit 632 does not associate the identification information with the power information. The notification unit 640 notifies the user to that effect (step S210), and the association process ends. By these processes, it is possible to prevent a plurality of identification information from being associated with the power information related to one charge.

For example, as a situation in which a plurality of identification information can be associated with the power information related to one charge, the identification information of the battery 200 or the charger 300 and the power information related to the charging are from the plurality of terminal devices 500. It is possible that the power was received at a close timing. In this case, the information management unit 632 cannot determine which of the plurality of received identification information the received power information should be associated with. Further, as another situation, when charging the battery 200, it is conceivable that the user simply reads a plurality of identification information by erroneous operation and transmits the plurality of identification information to the charging information management device 600.

Generally, in the form of providing the battery service, the user is often managed in association with the rented battery 200 or the charger 300. Therefore, if a plurality of identification information is erroneously associated with the power information related to one charge, an accident may occur in which the erroneously associated user is charged incorrectly. There is sex. On the other hand, according to the charging information management system 100 of the present embodiment, when the identification information of a plurality of chargers 300 is included in the target identification information, the association with the power information is not performed. Therefore, it is possible to prevent such an accident from occurring.

On the other hand, if it is determined in step S208 that the target identification information includes only the identification information of the charger 300 of 1 or less, the information management unit 632 uses the power information received after the charging start time as the target instruction-specific information. The charging information is generated in association with the above, and the generated charging information is recorded in the storage unit 620 (step S209). For example, the information management unit 632 records the generated charging information in the mode of the charging information management table T4 shown in FIG. 7 below.

FIG. 7 is a diagram showing an example of a charging information management table. For example, the charging information management table T4 may be created in advance in the storage unit 620, or may be created when it does not exist when associating each information. The charge information management table T4 is composed of one or more records having each value of charge start time, charger ID, battery ID, reception time, and cumulative electric energy. The charging start time, the charger ID, and the battery ID are as described above, and the value of the receiving time represents the time when the power information is received in the charging information management device 600. The example of FIG. 7 shows a case where charging information having 10:05 as the charging start time is added to the charging information management table T4 that holds the charging information generated by the past association processing.

In the charging information management table T4 in the state illustrated in FIG. 7, the information management unit 632 associates the power information received after the charging start time specified in step S205 with the identification information of the battery 200 and the charger 300. Generated.

Further, the charging information management system 100 of the embodiment acquires identification information and power information of the battery 200 and the charger 300 from the terminal device 500 by the charging information management device 600 having a communication function, and obtains the identification information and the power information of each identification information. Correspondence can be made based on the reception timing and the charge start timing of the battery 200 specified by the power information. Therefore, according to the charging information management system 100 of the embodiment, it is possible to manage the charge amount of the charger 300 which does not have the communication function.

Further, in the charging information management system 100 of the embodiment, the power meter 400 is installed between the charger 300 and the power source that supplies power to the charger 300 via the power meter 400, and is wirelessly connected to the terminal device 500. It is communicably connected, and the terminal device 500 includes a power information acquisition unit that acquires power information from the power meter 400 via wireless communication. According to such a configuration, the user can acquire the power information regarding the charging of the battery 200 to the terminal device 500 without physically operating the power meter 400 connected to the power outlet. Generally, since the power outlet is often provided at a low position such as a floor or a wall, it takes time and effort to physically operate the device directly connected to the power outlet. On the other hand, according to the charging information management system 100 of the embodiment, since the power information can be acquired without physically operating the power meter 400, it is displayed on the battery 200 or the charger 300. It is possible to smoothly read the symbol and acquire the power information by using the terminal device 500.

In the description of the above embodiment, the case where the identification information is displayed on both the battery 200 and the charger 300 has been described, but this manages the usage amount of both the battery 200 and the charger 300. It is supposed to be done. However, when the user's identification information is associated with either the battery 200 or the charger 300, the identification information of both is not always required in the management of the charge amount. Therefore, in such a case, the identification information may be displayed on either the battery 200 or the charger 300. Further, in this case, the charging information management system 100 of the embodiment may be configured to acquire the identification information of either the battery 200 or the charger 300 and associate it with the power information.

Further, the charging information management device 600 may have the first function of the control unit 550 of the terminal device 500. In this case, the identification information acquisition unit 551 of the terminal device 500 acquires each image data of images of the symbols displayed on the battery 200 and the charger 300 from the image pickup unit 540, and the acquired image data is transferred to the charging information management device 600. It may be configured to transmit. Further, in this case, the information acquisition unit 631 of the charging information management device 600 recognizes each symbol displayed on the battery 200 and the charger 300 from each received image data, decodes each recognized symbol, and decodes the recognized symbol to the battery 200 and the battery 200. It may be configured to acquire the identification information of the charger 300.

Further, the power meter 400 may be configured to transmit power information to the charging information management device 600 instead of the terminal device 500.
