  The charging control unit 22 controls the charging of the battery unit 11 with the charging voltage supplied via the external connection terminal / charging terminal unit (charging terminal unit 10-1, external connection terminal 10-2) 10, and the battery. The charging state of the unit 11, the remaining battery level, the remaining battery level when charging is interrupted, the estimated charging completion time, and the like are managed.

  The CPU unit 23 executes a system program stored in the memory unit 21, various application programs, and the like, and executes various functions. In particular, in the present embodiment, the CPU unit 23 executes processing for detection of a charging state and charging interruption.

  FIG. 3 is a conceptual diagram for explaining information managed by the charging control unit 22 of the mobile phone according to the present embodiment. As described above, the charging control unit 22 controls the charging of the battery unit 11, and the charging state of the battery unit 11, the remaining battery level, the remaining battery level when charging is interrupted, the estimated charging completion time, and the charging interrupt application name Manage.

  As shown in the figure, the state of charge indicates “0: not charging, 1: charging, 2: interruption of charging”. The remaining battery level is a value from 0 to 100 (FULL)% and indicates the remaining battery level of the battery unit 11. Further, the remaining battery level at the time of charging interruption is a value of 0 to 100 (FULL)%, and indicates the remaining battery level of the battery unit 11 at the time when charging is interrupted. The estimated charge completion time is a value from 0 to 63 (in units of 5 minutes) obtained from the remaining battery level, and indicates the estimated time until the battery unit 11 is fully charged. The charging interruption application name is an application name that causes charging interruption, and is indicated by a numerical value set for each application.

  The charging control unit 22 updates the charging state of the battery unit 11, the remaining battery level, the remaining battery level at the time of charging interruption, the estimated charging completion time, and the charging interruption application name at a predetermined time interval or at a predetermined timing. Always keep the latest information. Note that the charging interruption application name may be managed by the CPU unit 23. Applications include incoming voice calls, email reception notifications, alarm activation, and web browsers.

  Next, the operation of the mobile phone 1 according to the present embodiment will be described. However, in the following, description of functions of normal mobile phones such as voice calls and mail reception will be omitted, and only operations related to charging interruption will be described.

  FIG. 4 is a flowchart for explaining the operation of the mobile phone 1 according to the present embodiment. The flowchart is executed when the battery unit 11 is being charged and when charging is interrupted. CPU part 23 acquires a battery state from charge control part 22 (Step S10). CPU part 23 judges whether charge was interrupted from the acquired battery state (Step S12). If the charging is not interrupted (NO in step S12), the process returns to step S10. On the other hand, when charging is interrupted (YES in step S12), the CPU unit 23 acquires the remaining battery level at the time of charging interruption from the charging control unit 22 (step S14). Next, the CPU unit 23 determines whether any application is being executed (step S16).

  If any application is being executed (YES in step S16), the application name is acquired and stored as the charge interruption application name shown in FIG. 3 (step S18). Next, it is determined whether or not the currently executed application is terminated (step S20). If the application has not ended (NO in step S20), step S20 is repeated, and when the application ends (YES in step S20), the CPU unit 23 determines whether the remaining battery level or charging is interrupted from the charging control unit 22. The remaining battery level and the estimated charging completion time are acquired (step S22). Next, the main display unit 5 displays a charging interruption message indicating that charging has been interrupted, the estimated charging completion time, the remaining battery level at the time of charging interruption, the current remaining battery level, and the application name that caused the interruption. Display (step S24).

  Here, execution of an application during charging and termination of the application will be briefly described. For example, when an incoming call is received during charging, charging is automatically interrupted and an application relating to a voice call is automatically executed. Thereafter, when the user performs an operation to make a voice call and disconnects the line after the call ends, the application ends at that point. Then, when the application ends, a charging interruption message is displayed on the main display unit 5. Since the user confirms the charging interruption message after the application ends, charging can be resumed without forgetting that charging was in progress.

  On the other hand, if the application has not been executed at the time of charging interruption (NO in step S16), the CPU 23 determines whether or not a predetermined time T1 (for example, 5 minutes) has elapsed (step S26). ). If the predetermined time T1 has not elapsed (NO in step S26), the process returns to step S16 to determine whether or not the application is executed. If the application is executed before the predetermined time T1 has elapsed (YES in step S16), the above-described steps S18 to S24 are executed.

  That is, when charging is interrupted, some application (application that is executed regardless of the user's intention, such as incoming voice call or email) is already executed, or when charging is interrupted, the application was not executed. When any application is executed within the predetermined time T1, a charge interruption message is displayed at the end of the application to notify the necessity of recharging. After the application ends, the user can know that recharging is necessary and can select whether to recharge or not.

  On the other hand, if no application is executed after the predetermined time T1 has elapsed (YES in step S26), for example, the mobile phone 1 is opened, the key unit 6 is operated, or some user operation is performed. It is determined whether there has been (step S28). If there is no user operation (NO in step S28), it is determined whether or not a predetermined time T2 (for example, 10 minutes) has elapsed (since YES in step S28) (step S30).

  If the predetermined time T2 has not elapsed (NO in step S30), the process returns to step S28 to determine whether or not the user operation is performed. If there is a user operation before the predetermined time T2 has elapsed (YES in step S28), the CPU unit 23 determines from the charge control unit 22 that the remaining battery level, the remaining battery level when charging is interrupted, and the completion of charging. The predicted time is acquired (step S32), and a charging interruption message indicating that charging has been interrupted, charging completion prediction time, remaining battery level at the time of charging interruption, and current remaining battery level is displayed on the main display unit 5. (Step S34).

  That is, even if the user interrupts the charging for some purpose, the application is not started immediately (in this embodiment, at least a time equal to or longer than T1 has elapsed since the charging is interrupted). When the mobile phone 1 is opened or an application is started), a charging interruption message is displayed at that time to notify the necessity of recharging. The user can know that recharging is necessary when performing some operation, and can select whether to recharge or not.

  On the other hand, if there is no user operation even after the predetermined time T2 has elapsed (YES in step S30), since the mobile phone 1 is not opened, the CPU unit 23 receives the remaining battery level from the charge control unit 22. The remaining battery level when charging is interrupted and the estimated charging completion time are acquired (step S36), and the charging is interrupted, the estimated charging completion time, the remaining battery level when charging is interrupted, and the current remaining battery level are indicated. The charging interruption message is displayed on the sub display unit 8 (step S34).

  In other words, when the user interrupts the charging for some purpose and the application is not started and no operation is performed (in this embodiment, at least the time T1 + T2 has elapsed since the charging was interrupted). Since there is a high possibility that the user has forgotten recharging, displaying the charging interruption message on the sub display unit 8 informs the necessity of recharging. The user can know that recharging is necessary when performing some operation, and can select whether to recharge or not.

  In addition, it is possible to detect whether the mobile phone 1 is in an opened state or a closed state with existing technology. As described above, when it is possible to detect whether the mobile phone 1 is in an opened state or a closed state, it is displayed on the main display unit 5 or on the sub display unit 8 according to the state. You may make it distribute whether to display.

  In any case, after displaying the charging interruption message, the CPU unit 23 acquires the charging state from the charging control unit 22, determines whether or not the charging is restarted (step S40), and the charging is not restarted. In step S28, the above-described steps S28 to S38 are repeatedly executed. That is, in the case where recharging is not performed even though the charging interruption message is displayed, if there is a user operation within a predetermined time T2 (10 minutes), the user operation is performed at the time when the user operation is performed. If there is no operation, a charge interruption message is displayed at a predetermined time T2 interval to notify the necessity of recharging.

  FIGS. 5A and 5B are schematic diagrams illustrating an example of a charge interruption message in the mobile phone 1 according to the present embodiment. FIG. 5 (a) shows a case where some application (an application that is executed regardless of the user's intention, such as receiving a voice call or receiving an e-mail) is already executed when charging is interrupted, or is executed when charging is interrupted. This is an example of a charge interruption message displayed on the main display unit 5 when an application is executed within a predetermined time T1, although it has not been performed.

  In the upper part of the main display unit 5, an icon indicating that charging has been interrupted is displayed instead of an icon that simply indicates the charging level of the battery (the charging level is indicated by lighting of three blocks). Further, since the charging has been interrupted, the main display unit 5 displays a message 31 that prompts resumption of charging, an application name 32 that is a cause of the charging interruption, a battery remaining amount meter 33, and the like.

  On the other hand, FIG. 5B shows that some operation (in this case, the mobile phone 1 is opened or the application is started) without starting the application immediately, even though the user interrupts the charging for some purpose. It is an example of the charge interruption message displayed on the main display part 5 displayed at that time when it is performed. Basically, it is not different from FIG. 5A, but in this case, the application name 32 that is the cause of the interruption of charging is not displayed.

  In FIGS. 5A and 5B, options (buttons) 34 and 35 of “continue charging interruption state” and “stop charging interruption state” are displayed at the bottom of the main display unit 5. ing. In the flowchart shown in FIG. 4 described above, it has been described that the resumption of charging is automatically detected. However, in the illustrated example, the user can select whether or not to resume charging.

  6A to 6C are schematic diagrams illustrating detailed examples of the icon 30 indicating the interruption of charging, the battery remaining amount meter 33, and the like according to the present embodiment. FIG. 6A shows an icon 30 indicating the above-described charging interruption. The icon 30 indicating the interruption of charging is obtained by superimposing a mark indicating the meaning of “prohibited” or the like on a normal icon indicating the charging level by lighting the three blocks. You can let the user know. Further, as shown in FIG. 6B, when the battery unit 11 is fully charged (FULL), an icon 40 indicating full charge (FULL) may be displayed.

  As described above, conventionally, an icon representing a charging level by lighting three blocks has been used. However, in actuality, the charging level of the battery unit 11 is charged at “level 1” for lighting one block, “level 2” for lighting two blocks, and “level 3” for lighting three blocks. Has a width on the level. In particular, “level 3” that lights three blocks does not always indicate full charge (FULL charge).

  Therefore, in the present embodiment, a line indicating the current remaining battery level on the remaining battery level as shown in FIG. 6C is displayed in the charging suspension message prompting recharging, which is displayed when the charging is suspended. A battery level meter 33 is displayed on which L1 and a line L2 indicating the remaining battery level when charging is interrupted are drawn. At a glance, the remaining battery level meter 33 can easily know the remaining battery level when charging is interrupted in addition to the current remaining battery level.

  According to the present embodiment, if any application is executed at the time when charging is interrupted, or if any application is executed within a predetermined time, recharging is prompted after the application execution is completed. The charging status is displayed along with the charging interruption message, and when charging is interrupted, if any application is not executed, charging is interrupted to prompt recharging when some operation is performed by the user. Since the charging status of the battery unit is displayed along with the message, even if charging is interrupted, the user is encouraged to resume charging without sacrificing the user's convenience. It is possible to prevent the battery from becoming insufficient.

  The display form of the battery remaining amount meter 33 is not limited to the display form described above, and may be a circular shape or a rod shape. The current battery remaining amount and the remaining battery amount at the time of charging interruption are also shapes, colors, etc. You may express by changing.

  In the above-described embodiment, a mobile phone has been described as an electronic device. However, the present invention is not limited to this, and a digital camera, a portable game machine, a media player, an electronic book, or the like that requires charging may be used.
