  In step S550, main control unit 110 determines whether or not to display the battery status on main display unit 130. This determination is made based on user settings defined in the terminal setting memory 124. If main control unit 110 determines that the battery status is displayed on main display unit 130 (YES in step S550), control is switched to step S560. Otherwise (NO in step S550), main control unit 110 switches control to step S565.

  In step S560, main control unit 110 determines the display mode of the screen on main display unit 130, and outputs an image on the screen according to the determined content.

  In step S565, the main control unit 110 causes the LED and other light emitting units 132 to execute a display for notifying the remaining battery level or a display according to preset conditions.

  In step S570, main control unit 110 communicates with power supply control unit 115 to provide an external power source (for example, an external rechargeable battery connected to rechargeable battery 210 or other charging terminal 150) and an internal power source (for example, rechargeable battery 144). Alternatively, the state of the sub rechargeable battery 344) is confirmed.

  In step S580, main controller 110 determines whether there is a change in the power supply environment of portable terminal 100 based on the input signal. Here, the change in the power supply environment includes, for example, whether an external rechargeable battery or a built-in rechargeable battery is removed, and whether the mobile terminal 100 is connected to an AC power supply. When main controller 110 determines that the power supply environment has changed (YES in step S580), control is returned to step S510. Otherwise (NO in step S580), main control unit 110 switches control to step S590.

  In step S590, main control unit 110 determines whether or not the battery to be charged has run out or cannot be charged based on the signal from power supply control unit 115. When main controller 110 determines that the battery to be charged is exhausted or cannot be charged (YES in step S590), the control ends. Otherwise (NO in step S590), main control unit 110 returns control to step S560.

[Display mode]
With reference to FIG. 6 to FIG. 10, screen display modes in the mobile terminal 100 will be described. 6 to 10 are diagrams showing display modes of the screen on the main display unit 130, respectively.

  FIG. 6 is a diagram illustrating a display mode when the mobile terminal 100 includes a plurality of rechargeable batteries. Specifically, the mobile terminal 100 displays an icon representing the state of the rechargeable battery on the main display unit 130 for each rechargeable battery, and distinguishes the state of charge of each battery by the color or shape of the icon. The state of the rechargeable battery includes, for example, whether the rechargeable battery is used or charged, and the remaining amount of the rechargeable battery.

  In a certain situation, the main display unit 130 displays icons 610 and 620. Icon 610 represents the state of charge of rechargeable battery 144, for example. Icon 620 represents the charging state of sub rechargeable battery 344.

  The display mode is not limited to the battery unit. In other aspects, for example, the unit of cells constituting one rechargeable battery may be used as the display unit. In this case, for example, a ratio such as 25%, 50%, 75%, or 100% may be used as a display unit.

  FIG. 7 is a diagram showing a mode in which the remaining amounts of a plurality of rechargeable batteries are totaled and displayed with one icon or a numerical value. In a certain situation, the main display unit 130 displays an icon 710.

  For example, the icon 710 adds up the remaining amount of the rechargeable battery 144 and the remaining amount of the sub-rechargeable battery 344, and the remaining amount of one icon based on the ratio of the full charge capacity of the rechargeable battery 144 and the full charge capacity of the sub rechargeable battery 344 Is displayed.

  FIG. 8 is a diagram illustrating battery priorities in the mobile terminal 100. In a certain situation, the main display unit 130 displays an icon 810 and an icon 820. The icon 810 represents the charge capacity of the rechargeable battery 144, for example. The icon 820 represents the remaining amount of the sub rechargeable battery 344 or the remaining amount of the detachable rechargeable battery 210 connected to the outside of the mobile terminal 100.

  Here, as indicated by the icon 810, the numeral 1 is circled. This display indicates that the rechargeable battery 144 is used first. Thereby, the user of the portable terminal 100 can easily grasp from which rechargeable battery power is supplied.

  FIG. 9 shows a mode indicating whether the rechargeable battery is used or charged in the mobile terminal 100. In a certain situation, the main display unit 130 displays an icon 910. The icon 910 indicates that the built-in rechargeable battery 144 is charged from the rechargeable battery 210 connected to the outside of the mobile terminal 100.

  FIG. 10 is a diagram showing a mode of displaying the remaining amount of the rechargeable battery in still another aspect. In another aspect, the mobile terminal 100 displays an icon 1000. An icon 1000 indicates the remaining amount of the rechargeable battery 144.

  In addition, the display mode of the state of a rechargeable battery is not restricted to what is shown by FIGS. For example, when the mobile terminal 100 has the light emitting unit 132, the state of the rechargeable battery may be displayed by the light emission pattern by the light emitting unit 132. The display mode may include individual or a combination thereof depending on, for example, lighting time, blinking interval, lighting color, and the like.

  As described above, when a plurality of rechargeable batteries are connected in portable terminal 100 according to the present embodiment, particularly when externally connected, portability may be impaired. For the user of the mobile terminal 100, regarding the portability, the mobile terminal 100 to which the rechargeable battery is not connected exceeds the mobile terminal 100 to which the rechargeable battery is connected. Therefore, it is effective to be able to set which battery the mobile terminal 100 uses or which battery is charged.

  In addition, when mobile terminal 100 according to another embodiment has a plurality of batteries built therein, if the battery with no remaining battery charge can be replaced, the user does not bother to turn off and on the power supply. The mobile terminal 100 can be used continuously without waiting for the mobile terminal 100 to start.

  In another embodiment, when the mobile terminal 100 has a plurality of rechargeable batteries, the mobile terminal 100 has the ability to display the remaining amount of each rechargeable battery, so that the user can easily check the state of each rechargeable battery. Can grasp.

  Further, in the mobile terminal 100 having an excellent information processing function such as a so-called smartphone, a terminal (microUSB) that receives power supply is commonly used for both AC power supply and external battery. Thereby, the user of the portable terminal 100 recognizes the power supply source connected to the terminal, thereby operating the built-in rechargeable battery or the externally connected battery (discharge, charge) and its Priorities can be set.

  For example, when the mobile terminal 100 has a plurality of terminals, the plurality of terminals may be used as a determination as to whether or not a rechargeable battery is connected to the outside. In this case, if the external rechargeable battery is configured to have a plurality of connecting portions, the mobile terminal 100 detects the signal value at that time by adapting each terminal and each connecting portion, thereby detecting the external value. It can be recognized that the rechargeable battery is connected to the battery.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
