The graph which showed an example of the relation between time and battery charge.

  First, the outline of the configuration of the power management system 100 will be described with reference to FIG.

  The power management system 100 determines whether or not charging of the terminal (monitored person's terminal 1) carried by the monitored person is necessary, and reports the necessity of this charging to the supervisor's terminal (monitored person's terminal 2). The power management of the terminal carried by the person being monitored is performed. In the power management system 100, the person to be monitored is a side that is monitored whether or not charging of the terminal carried by the person to be monitored is necessary, and is, for example, a child. The monitor is a side who monitors the necessity of charging of the terminal carried by the person being monitored, and is, for example, a parent.

  The power management system 100 includes a monitoring target person terminal 1, a monitoring person terminal 2 and a server 3.

  The monitoring target person terminal 1 is a terminal which the monitoring target person carries and uses. As the monitoring target person terminal 1, a terminal capable of transmitting and receiving data (information) is used, and for example, a mobile phone terminal, a tablet terminal, a game machine or the like is used. The monitoring target person terminal 1 is provided with a power supply unit 1A.

  The power supply unit 1 </ b> A supplies power to each unit of the monitoring target person terminal 1. The power supply unit 1A is, for example, a storage battery. Electric power is stored in the power supply unit 1A from the external power supply S.

  The monitoring target person terminal 1 includes a control unit 10 that controls the monitoring target person terminal 1. The control unit 10 includes a battery remaining amount information acquisition unit 11, a charge detection unit 12, and a transmission / reception unit 13.

  The battery remaining amount information acquiring unit 11 acquires battery remaining amount information indicating the battery remaining amount of the power supply unit 1A. The battery remaining amount information acquiring unit 11 continuously acquires the battery remaining amount information from the power supply unit 1A. In the present specification, the battery remaining amount of the power supply unit 1A is expressed on the basis of the battery remaining amount at the full charge, with the battery remaining amount at the full charge being 100.

  The charge detection unit 12 detects whether the power supply unit 1A is being charged. The charge detection unit 12 detects that the charging of the power supply unit 1A is started by detecting that the current starts to flow from the external power supply S to the power supply unit 1A. When the charge detection unit 12 detects that the charging of the power supply unit 1A is started, the charge detection unit 12 generates charge start information indicating that. Further, the charge detection unit 12 detects that the charging of the power supply unit 1A is ended by detecting the stop of the current flowing from the external power supply S to the power supply unit 1A. When the charge detection unit 12 detects that the charging of the power supply unit 1A is ended, the charge detection unit 12 generates charge end information indicating that. In the present specification, the charge start information and the charge end information may be collectively referred to as charge information.

  The transmitting and receiving unit 13 transmits and receives data to and from the server 3 described later.

  The supervisor terminal 2 is a terminal used by the supervisor. As the supervisor terminal 2, a terminal capable of transmitting and receiving data is used, and for example, a personal computer or a high-performance mobile phone terminal is used. The supervisor terminal 2 includes a display unit 2A and an input unit 2B. The display unit 2A is a portion that displays information for transmitting information to the supervisor and a screen stored in advance. For example, a liquid crystal display is used as the display unit 2A. The input unit 2 </ b> B is a portion where the supervisor performs an operation. For example, a keyboard or a touch panel is used as the input unit 2B. Data is input to the supervisor terminal 2 by the supervisor operating the input unit 2B.

  The supervisor terminal 2 includes a control unit 20 that controls the supervisor terminal 2. The control unit 20 includes a threshold information setting unit 21, a determination time information setting unit 22, a display control unit 23, and a transmission / reception unit 24.

  The threshold information setting unit 21 sets a threshold (remaining battery level) as a reference for determining the necessity of charging (of the power supply unit 1A) of the monitoring target person terminal 1. The threshold is set by operating the input unit 2B of the supervisor terminal 2.

  The determination time information setting unit 22 sets a determination time at which the charge necessity determination unit 32 described later determines whether the monitoring target person terminal 1 needs charging. The determination time is set by operating the input unit 2B of the supervisor terminal 2.

  The display control unit 23 controls the display unit 2A to display information to be transmitted to the supervisor and a screen stored in advance. The display control unit 23 can perform, for example, control of causing the display unit 2A to display the determination result by the charging necessity determination unit 32 described later.

  The transmitting and receiving unit 24 transmits and receives data to and from the server 3 described later.

  The server 3 is configured to be able to transmit and receive data with the monitoring target person terminal 1 and the monitoring person terminal 2. The server 3 includes a control unit 30 that controls the server 3. The control unit 30 includes a battery remaining amount information storage unit 31, a charge necessity determination unit 32, a threshold information storage unit 33, a determination time information storage unit 34, a charge information storage unit 35, and a transmission / reception unit 36.

  The remaining battery charge information storage unit 31 stores the remaining battery charge information from the remaining battery charge information acquisition unit 11 of the person-to-be-monitored terminal 1. Of the remaining battery charge information acquired by the remaining battery charge information acquisition unit 11, the remaining battery charge information storage unit 31 reads the remaining battery charge information necessary for charge necessity determination by the charge necessity determination unit 32 described later. The information on the remaining amount of the battery is stored.

  The charging necessity determination unit 32 determines whether it is necessary to charge the monitoring target person terminal 1. This determination of necessity of charging is performed based on the remaining battery amount information stored in the remaining battery amount information storage unit 31.

  The threshold information storage unit 33 stores threshold information indicating the threshold set by the threshold information setting unit 21 of the supervisor terminal 2.

  The determination time information storage unit 34 stores determination time information indicating the determination time set by the determination time information setting unit 22 of the supervisor terminal 2.

  The charge information storage unit 35 stores charge information (charge start information and charge end information) generated by the charge detection unit 12 of the monitoring target person terminal 1.

  The transmission and reception unit 36 transmits and receives data to and from the monitoring target person terminal 1 and the monitoring person terminal 2.

  In the control unit 30 of the server 3 configured as described above, the remaining battery charge information storage unit 31 receives the determination from the remaining battery charge information acquisition unit 11 based on the determination time information stored in the determination time information storage unit 34. Information on remaining battery power of power supply unit 1A at time is stored. As a result, the remaining battery amount information storage unit 31 stores the remaining battery amount information at the determination time every day.

  Further, based on the charging information stored in charging information storage unit 35, battery remaining information storage unit 31 determines the battery remaining information of power supply unit 1A when charging is started, and the power supply when charging is completed. It accumulates the remaining battery charge information of part 1A.

  First, based on the history of the remaining battery charge information stored in the remaining battery charge information storage unit 31, the charge necessity determination unit 32 will be used from the present (determination time) to the determination time of the next day The battery usage is predicted (this predicted battery usage is referred to herein as "the predicted battery usage"). Then, the charging necessity determination unit 32 determines whether or not charging of the monitoring target person terminal 1 should be performed, by comparing the current battery remaining amount and the predicted battery usage amount.

  More specifically, in the case where the difference between the current battery remaining amount and the predicted battery used amount (the value obtained by subtracting the predicted battery used amount from the current battery remaining amount) is equal to or less than the threshold stored in the threshold information storage unit 33 The charging necessity determination unit 32 determines that charging of the person-to-be-monitored terminal 1 is required. On the other hand, if the difference between the current remaining battery charge and the predicted battery usage is larger than the threshold stored in the threshold information storage unit 33, the charge necessity determination unit 32 does not need to charge the monitoring target person terminal 1 Determine that there is. If it is determined that the charge is necessary, the charge necessity determination unit 32 generates charge necessary information indicating the determination result that the charge is necessary.

  Hereinafter, control regarding accumulation of battery remaining charge information in the power management system 100 will be described. As a premise of control relating to the accumulation, setting of the determination time is performed in advance.

  First, under the control of the display control unit 23, a setting screen stored in advance in the monitor terminal 2 is displayed on the display unit 2A of the monitor terminal 2. The setting screen is configured to be able to set a determination time for determining whether or not charging of the person-to-be-monitored terminal 1 is required. The supervisor operates the input unit 2B to input the determination time.

  If it is determined in the control described later (step S70 shown in FIG. 3) that charging of the monitoring target person's terminal 1 is necessary, charging is performed until the monitoring target person's terminal 1 is taken out of the house next. There is a need. Therefore, it is desirable that the judgment time be a time when the person to be monitored (child) is at home (the person to be monitored terminal 1 is at home), and there is enough time until the person to be monitored next goes out. Therefore, it is desirable that the determination time be a time before the person to be monitored goes to bed. In the present embodiment, the determination time is 21:00. However, the determination time may be determined according to the life cycle of the person to be monitored.

  Determination time information is set in the determination time information setting unit 22 by the operation of the input unit 2B. The determination time information set in the determination time information setting unit 22 is transmitted to the transmission / reception unit 36 of the server 3 via the transmission / reception unit 24. The determination time information received by the transmission and reception unit 36 is stored in the determination time information storage unit 34.

  Next, a specific flow of control relating to storage of remaining battery amount information in the power management system 100 will be described with reference to FIGS. 1 and 2.

  The battery remaining amount information acquiring unit 11 continuously acquires battery remaining amount information from the power supply unit 1A (step S10). The battery remaining amount information storage unit 31 reads the determination time information stored in the determination time information storage unit 34 (step S20). When the determination time (21 o'clock) is reached based on the determination time information stored in the determination time information storage unit 34, the battery remaining amount information storage unit 31 receives the determination at the determination time (21 o'clock) from the battery remaining amount information acquisition unit 11. The remaining battery amount information of the power supply unit 1A is accumulated (step S30). By repeating the steps S10 to S30, the battery residual amount information accumulation unit 31 accumulates a history of the battery residual amount information (battery residual amount information at 21:00 every day).

  Hereinafter, control regarding determination of necessity of charging in the power management system 100 will be described. A threshold is set in advance as a premise of control relating to the determination of necessity of charging. In the following, it is assumed that the process from step S10 to step S30 has already been performed, and the battery remaining amount information storage unit 31 has a history of battery remaining amount information for the past one month stored. .

  First, under the control of the display control unit 23, a setting screen stored in advance in the monitor terminal 2 is displayed on the display unit 2A of the monitor terminal 2. The setting screen is configured to be able to set a threshold serving as a reference for determining whether or not charging of the person-to-be-monitored terminal 1 is required. The supervisor operates the input unit 2B to input a threshold. In the present embodiment, the threshold is 20.

  The threshold information is set in the threshold information setting unit 21 by the operation of the input unit 2B. The threshold information set in the threshold information setting unit 21 is transmitted to the transmission / reception unit 36 of the server 3 via the transmission / reception unit 24. The threshold information received by the transmitting and receiving unit 36 is stored in the threshold information storage unit 33.

  Next, a specific flow of control regarding determination of necessity of charging in the power management system 100 will be described using FIG. 1 and FIG. 3.

  Next, based on the determination time information stored in the determination time information storage unit 34, when the determination time (21 o'clock) comes, the charge necessity determination unit 32 determines the remaining battery amount stored in the battery remaining amount information storage unit 31. Based on the history of the information, the daily battery usage in the past is calculated (step S40). Hereinafter, a method of calculating the battery usage amount for each past day will be described using FIG. 4.

  The day (hereinafter, simply referred to as “the day”) on which the necessity of charging determination is performed is, for example, the Saturday of the fourth week of a certain month. Of the remaining battery charge information of the person to be monitored 1 stored in the remaining battery charge information storage unit 31, the remaining battery charge information of the latest predetermined period (in the present embodiment, up to four weeks before the present day) is used Calculate the daily battery usage in the past.

  First, as shown in FIG. 4 (a), the difference between the remaining battery level at 21:00 on the day (Saturday 4th) and the remaining battery level at 21:00 on the previous day (Friday 4th): Calculate battery usage. In the present embodiment, since the battery remaining amount at 21:00 on the day is 40 and the battery remaining amount at 21:00 on the previous day is 50, the battery usage from 21:00 on the previous day to 21:00 on the day is 10. Here, the battery usage from the judgment time of the previous day (21 o'clock) to the judgment time of the day (21 o'clock) is treated as the battery usage of the day.

  Calculate the daily battery usage for the past week in the same way as this. As shown at the bottom of FIG. 4 (a), the battery usage in the fourth week is 30, 20, 10, 20, 10, 20, 10 from Sunday to Saturday, respectively. In addition, since the remaining battery capacity on Tuesday of the fourth week is 20 and the remaining battery capacity on Wednesday of the fourth week is 80, it is estimated that charging was performed from 21:00 on Tuesday to 21:00 on Wednesday . In such a case, the difference between the fully charged battery remaining amount (100) and the battery remaining amount (80) on Wednesday is calculated as the battery used amount on Wednesday.

  The average value of the battery usage for the past one week is calculated as described above. In the present embodiment, the average battery usage in the past one week is 17 (rounded off after the decimal point). Therefore, from the tendency of the past week, the battery capacity temporarily estimated to be used the next day (Sunday of the fifth week) can be regarded as 17. The average battery usage amount for the last past week is referred to as an average usage amount A.

  Next, as shown in FIG. 4B, the battery usage of the past 1 day on the same day (Sunday) as the target day (the next day in the case of this embodiment) for which the predicted battery usage is to be calculated is calculated. . As shown in the rightmost row of FIG. 4 (b), the battery usage on the past Sunday is 20, 20, and 30 from the first week to the third week, respectively. In the present embodiment, since the determination time is set to 21:00, the day for which the predicted battery usage amount is to be calculated is the day after the charge necessity determination day (the current day). For example, the determination time is 2 am If the hour is set, the day for which the predicted battery usage is calculated is the current day.

  The average value of the battery usage on the past Sunday calculated in this manner is calculated. In the present embodiment, the average battery usage on the past Sunday is 23 (rounded to the nearest decimal point). Therefore, from the tendency due to the difference of the day of the week, the battery capacity temporarily predicted to be used the next day (Sunday of the fifth week) can be regarded as 23. The average battery usage of the same day as the target day for which the predicted battery usage is to be calculated is taken as the average usage B.

  The larger one of the average usage amount A and the average usage amount B calculated in this manner is set as the predicted battery usage amount predicted to be used by 21:00 on the next day from the present time (step S50). Therefore, in the present embodiment, the predicted battery usage is set to 23. By adopting the larger value of the average usage amount A and the average usage amount B as the predicted battery usage amount, it is determined that the battery remaining amount of the monitoring target person terminal 1 has a margin in the necessity determination of charging and It is possible to reduce the possibility of the occurrence of battery breakage.

  In addition, at the time of the calculation of the battery usage in the past, it is also possible to unconditionally set either the average usage A or the average usage B as the predicted battery usage. When the average usage amount A is set as the predicted battery usage, it is advantageous in that the recent trend of battery usage can be reflected in the predicted battery usage. Also, the life cycle of the person being monitored often varies depending on the day of the week, for example, having lessons on Tuesday. This difference in life cycle is considered to affect the battery usage of the monitoring target person terminal 1 as well. Therefore, when the average usage amount B is set as the predicted battery usage, it is advantageous in that the tendency of the battery usage according to the life cycle can be reflected in the predicted battery usage.

  Next, the charge necessity determination unit 32 reads the threshold information stored in the threshold information storage unit 33 (step S60). The charge necessity determination unit 32 determines the (current) battery remaining amount at 21:00 on the day acquired in step S30 shown in FIG. 2, the predicted battery usage amount set in step S50, and the threshold information storage unit Based on the threshold information stored in 33, it is determined whether or not charging of the person-to-be-monitored terminal 1 is required (step S70). The difference between the remaining battery capacity (40) and the estimated battery usage (23) at 21:00 on the day is 17. Here, the charging necessity determination unit 32 determines that charging of the monitoring target person terminal 1 is necessary if the difference is equal to or less than the threshold (“YES” in step S70). In the present embodiment, since the difference (17) is equal to or less than the threshold (20), it is determined that charging of the person-to-be-monitored terminal 1 is required. On the other hand, when the difference is larger than the threshold value, it is determined that charging of the person-to-be-monitored terminal 1 is unnecessary ("NO" in step S70).

  When it is determined by the charging necessity determination unit 32 that charging of the monitoring target person terminal 1 is unnecessary (“NO” in step S70), the control is temporarily ended.

  On the other hand, when the charging necessity determination unit 32 determines that charging of the monitoring target person terminal 1 is necessary ("YES" in step S70), the charging necessity information indicating the determination result that charging is necessary is generated. Do. The charge necessary information is transmitted to the transmission / reception unit 24 of the supervisor terminal 2 via the transmission / reception unit 36 (step S80). The display control unit 23 receives the charge necessary information received by the transmission / reception unit 24 and causes the display unit 2A of the supervisor terminal 2 to display the determination result indicating that the charge is necessary (step S90). On the display unit 2A, for example, “The battery of the portable terminal of the child is almost exhausted, and charging is required” is displayed. Thereby, the supervisor can know that charging of the person-to-be-monitored terminal 1 is necessary.

  When the monitor learns that charging of the monitoring target person's terminal 1 is necessary, the monitoring person urges the monitoring target person to charge the monitoring target person's terminal 1 orally or by telephone. In response to this, the person to be monitored connects the power supply unit 1A of the person terminal 1 to be monitored to the external power supply S, and starts charging the person terminal 1 to be monitored (step S100).

  When charging of the monitoring target person terminal 1 is started, the charge detecting unit 12 of the monitoring target person terminal 1 detects that the current starts to flow between the external power source S and the power source unit 1A. When detecting that the current starts to flow, the charge detection unit 12 generates charge start information indicating that charging of the monitoring target person terminal 1 has been started. The charge start information is transmitted to the transmission / reception unit 36 of the server 3 via the transmission / reception unit 13 (step S110). The charging start information received by the transmitting and receiving unit 36 is transmitted to the transmitting and receiving unit 24 of the supervisor terminal 2. The display control unit 23 receives the charge start information received by the transmission / reception unit 24 and displays on the display unit 2A of the supervisor terminal 2 that charging of the person-to-be-monitored terminal 1 has started (step S120). For example, “charging of the portable terminal of the child has been started” is displayed on the display unit 2A.

  Here, control ends once. At 21:00 on the next day, the processes from step S40 to step S120 are performed again.

  In the power management system 100 according to the present embodiment configured as described above, the supervisor can automatically know the necessity of charging the monitoring target person terminal 1. Therefore, when the supervisor is informed that the charging of the person to be monitored 1 is necessary, the person to be monitored is notified of the need to charge the person to be monitored 1 and the monitoring person is monitored The subject person terminal 1 can be urged to be charged.

  Further, the supervisor can automatically know whether or not charging of the person-to-be-monitored terminal 1 has actually started (see step S120). Therefore, the surveillance person can save the trouble of seeing and confirming whether the charging of the person-to-be-monitored 1 is actually performed.

  As described above, in the power management system 100 according to the present embodiment, the supervisor determines whether or not charging of the monitoring target person terminal 1 is necessary, and whether charging has actually been started, etc. The charge condition of the person-to-be-monitored terminal 1 can be appropriately grasped. Therefore, the supervisor can manage the charge condition of the person-to-be-monitored terminal 1 and thus can suppress the occurrence of battery exhaustion of the person-to-be-monitored terminal 1.

  Further, since the power management system 100 according to the present embodiment can predict the battery usage up to the next determination time, the supervisor can urge the person to be monitored to charge in advance. Therefore, when the person to be monitored is not in the place where the person to be monitored terminal 1 can be charged immediately, the battery remaining amount of the person to be monitored terminal 1 does not need to become scarce and burnt.

  Further, as described above, in the power management system 100 according to the present embodiment, whether or not charging of the monitoring subject terminal 1 is necessary is determined based on the past actual usage state of the monitoring subject terminal 1. Therefore, in the power management system 100 according to the present embodiment, it is possible to improve the accuracy of the battery usage (predicted battery usage) predicted to be used by the next determination time.

As described above, the power management system 100 according to the present embodiment includes the monitoring target person terminal 1 carried and used by the monitoring target person and the monitoring person terminal 2 used by the monitoring target, and the monitoring target person terminal 1 is a power management system 100 for managing the power supply of the first embodiment, and includes a battery remaining amount information storage unit 31 for storing battery remaining amount information indicating a battery remaining amount of the monitoring target person terminal 1; Based on the remaining battery charge information of the monitoring target person terminal 1 accumulated in the past, the predicted battery usage amount that will be used from now to a certain period later is calculated, and the current battery remaining is calculated. A charge necessity determination unit 32 that determines whether charging is necessary or not by comparing amount information with the predicted battery usage, and a display control unit that notifies the supervisor terminal 2 of the determination result by the charge necessity determination unit 32 23 (charging necessity notification control unit) It is intended to Bei.
By configuring in this manner, the supervisor can know whether it is necessary to charge the monitoring target person's terminal 1 and, consequently, the occurrence of battery exhaustion of the monitoring target person's terminal 1 can be suppressed.

It is not something to be done. The period of the history of the remaining battery amount information may be, for example, several months in order to improve the accuracy of the determination of necessity of charge by the charge necessity determination unit 32.

  Further, in the present embodiment, by displaying the charge start information and the charge necessary information on the display unit 2A of the supervisor terminal 2, the fact that the charge of the person to be monitored 1 has been started and that the charge is necessary Although the notification is made, the present invention is not limited to this. The notification means to the supervisor may be, for example, voice or vibration. Along with this, the charging necessity notification control unit and the charging start information notification control unit according to the present invention may control the voice output unit or the vibration output unit.

  Further, in the present embodiment, when it is determined by the charging necessity determination unit 32 that charging of the person-to-be-monitored terminal 1 is required, the charging necessary information is transmitted only to the supervisor terminal 2. The present invention is not limited to this. The charging required information may be transmitted not only to the supervisor terminal 2 but also to the surveillance target person terminal 1. This makes it possible to notify the person to be monitored that charging is necessary, and, in turn, the person to be monitored charges the person terminal 1 of the person to be monitored 1 before being prompted by the monitor verbally or by telephone. It can start. In addition, when the notification means such as display, voice, vibration, etc. notify that the monitoring target person terminal 1 needs charging, the notification means does not stop until the charging of the monitoring target person terminal 1 is started. It may be configured. As a result, the person to be monitored can be forced to start charging semi-forcefully.

  Moreover, in the present embodiment, although the charge necessity determination unit 32 determines the necessity of charge every day, the interval between the determination and the next determination is not limited. For example, it may be every other day.

It is also possible to notify the observer of the fact that it has been done.

  Further, in the present embodiment, when the charge necessity determination unit 32 calculates the daily battery usage amount in the past, if the battery remaining amount on the day is larger than the battery remaining amount on the previous day, the battery is fully charged. The difference between the remaining battery level and the remaining battery level on the current day was calculated on the basis of the current battery level, but the present invention is not limited to this. Hereinafter, the flow of control relating to storage of remaining battery amount information in the power management system 100 according to the second embodiment of the present invention will be described with reference to FIGS. 1 and 5.

  The flow of control related to the storage of the battery residual amount information in the power management system 100 according to the second embodiment shown in FIG. 5 is the flow of the control related to the storage of the battery residual information in the power management system 100 according to the first embodiment (FIG. The difference from 2) is that the battery residual amount information is acquired when charging is performed between 21:00 of the previous day and 21:00 of the day. Hereinafter, only steps different from the first embodiment will be described.

  When charging of the monitoring target person's terminal 1 is started between 21:00 of the previous day and 21:00 of the current day (step S31), the charge detecting unit 12 of the monitoring target person's terminal 1 controls the external power source S and the power source unit 1A. Detect that the current starts to flow between When detecting that the current starts to flow, the charge detection unit 12 generates charge start information indicating that charging of the monitoring target person terminal 1 has been started. The charge start information is transmitted to the transmission / reception unit 36 of the server 3 via the transmission / reception unit 13 (step S32). The charging start information received by the transmitting and receiving unit 36 is transmitted to the transmitting and receiving unit 24 of the supervisor terminal 2. The display control unit 23 receives the charge start information received by the transmission / reception unit 24 and displays on the display unit 2A of the supervisor terminal 2 that charging of the person-to-be-monitored terminal 1 has started (step S33).

  Further, the charge start information received by the transmission / reception unit 36 is stored in the charge information storage unit 35. The battery remaining amount information storage unit 31 acquires battery remaining amount information at the start of charging based on the charge start information stored in the charge information storage unit 35 (step S34).

  When charging of the monitoring target person terminal 1 ends (step S35), the charge detection unit 12 generates charging end information indicating that charging of the monitoring target person terminal 1 has ended. The charge end information is transmitted to the transmitting and receiving unit 36 of the server 3 via the transmitting and receiving unit 13. The charge end information received by the transmission / reception unit 36 is stored in the charge information storage unit 35 (step S36). Based on the charge end information stored in the charge information storage unit 35, the battery remaining amount information storage unit 31 acquires battery remaining amount information at the time of charge end (step S37). In addition, when charging of the monitoring object person terminal 1 is performed multiple times between 21:00 of the previous day and 21:00 of the day, the said step S31 to the said step S37 are performed each time.

  At 21:00 on the day, the remaining battery charge information storage unit 31 receives the remaining battery charge information acquisition unit 11 of the power supply unit 1A based on the determination time information (see step S20) stored in the determination time information storage unit 34. The remaining battery charge information at 21:00 is acquired (step S38). By repeating the step S31 to the step S38, the battery remaining amount information storage unit 31 stores the history of the battery remaining amount information (at the start of charging for each day, the remaining amount of battery information at the end of charging and at 21:00) Is accumulated.

  Hereinafter, with reference to FIG. 6, in the step of calculating the daily battery usage in the past (step S40), the battery usage on the day when the charging of the monitoring target person terminal 1 in the second embodiment is performed. The calculation method of will be described. In addition, the graph shown in FIG. 6 has shown an example of the relationship between the time from 21:00 of the previous day to 21:00 on the day, and the battery remaining charge.

  As shown in FIG. 6, it is assumed that charging is performed from 21:00 on the previous day to 8:00 on the day (period A), and charging is further performed from 14:00 to 17:00 on the day (period C). Charging is not performed from 8 o'clock to 14 o'clock on the day (period B) and from 17 o'clock to 21 o'clock (period D) on the day. The remaining battery levels at 21:00 of the previous day and 8:00, 14:00, 17:00 and 21:00 of the day are 20, 90, 60, 80 and 70, respectively. The battery remaining amount at the time is obtained from the battery remaining amount information acquiring unit 11 based on the charge start information and the charge end information, as described above.

  In such a case, the battery usage on the day (the battery usage from 21:00 on the previous day to 21:00 on the day) is the first remaining battery charge information and the last battery remaining charge information during the period in which charging is not performed. Calculated based on the difference between Specifically, at 8 o'clock to 14 o'clock (period B) of the day, the battery remaining amount at 8 o'clock is 90, and the battery remaining amount at 14 o'clock is 60. Therefore, the battery usage amount in period B is 30 . Further, in the period from 17 o'clock to 21 o'clock (period D), the battery remaining amount at 17 o'clock is 80, and the battery remaining amount at 21 o'clock is 70, so the battery used amount in period D is 10. The battery usage on the current day is calculated by the sum of the battery usage in period B and the battery usage in period D. Therefore, the battery usage on the day is 40. In addition, when charge is not started at the determination time (21 o'clock) of the previous day, "the 1st battery residual amount information of the period in which charge is not performed" is 21 o'clock of the battery residual amount information of the previous day.

  As described above, the actual battery usage can be obtained by calculating the battery usage per day using the battery remaining amount at the start of charging and at the end of charging. Therefore, the accuracy of the predicted battery usage can be improved, and the reliability of the determination of necessity of charging performed by the determination unit of charging necessity 32 can be improved.

As described above, in the power management system 100 according to the second embodiment, the charging necessity determination unit 32 monitors the monitoring target between the predetermined time of the previous day and the predetermined time of the certain day. When the user terminal 1 is charged, based on the difference between the first remaining battery charge information in the non-charging period and the last remaining battery charge information in the non-charging period, The past daily battery usage is calculated.
By this configuration, the accuracy of the predicted battery usage can be improved.

  As mentioned above, although 2nd embodiment of this invention was described, the calculation method of the battery usage in case charge is performed is not limited to the said method, It is the method by which actual battery usage is computed. I hope there is.
