Since the mobile terminal 3 and the mobile terminal 4 have the same functional configuration and processing, detailed description of the mobile terminal 4 will be omitted in the following description.

  Here, the power feeding is to pass the power of the target mobile terminal to another mobile terminal. Power supply reduces the power of the target mobile terminal that is the power supply source, and increases the power of another mobile terminal that is the power supply destination. Conversely, charging means receiving power from another mobile terminal at the target mobile terminal. Charging reduces the power of another mobile terminal that is the charging source, and increases the power of the target mobile terminal that is the charging destination.

  FIG. 2 is a block diagram illustrating configurations of the mobile terminal 2, the mobile terminal 3, and the mobile terminal 4 according to the present embodiment. As shown in FIG. 2, the portable terminal 2 includes a battery 21, a power information transmission unit 22, a power information reception unit 23 (first power information reception unit), a target remaining power amount calculation unit 24 (target remaining power amount calculation unit). ), Target remaining power amount transmission unit 25, power supply target selection unit 26 (first power supply target selection unit), required remaining power amount calculation unit 27 (first required remaining power amount calculation unit), power supply unit 28 (first power supply unit) ), And the connector 58.

  The portable terminal 2, the portable terminal 3, and the portable terminal 4 are configured by hardware such as a CPU. FIG. 3 is a hardware configuration diagram of the mobile terminal 2, the mobile terminal 3, and the mobile terminal 4. As shown in FIG. 3, the portable terminal 2, the portable terminal 3 and the portable terminal 4 shown in FIG. 2 physically include a CPU 51, a RAM 52 and a ROM 53 which are main storage devices, and a keyboard and a mouse which are input devices.

The functions of the functional blocks shown in FIG. 2 are such that predetermined computer software is loaded on hardware such as the CPU 51 and RAM 52 shown in FIG. 3 to control the input device 54, the output device 55, and the communication under the control of the CPU 51. This is realized by operating the module 56 and reading and writing data in the RAM 52 and the auxiliary storage device 57.

  Hereinafter, each functional block will be described based on the functional blocks shown in FIG. First, each functional block of the mobile terminal 2 will be described.

  The battery 21 is a battery that stores electrical energy (electric power) necessary for operating the function of the mobile terminal 2. Similarly, the battery 31 is a battery that stores electric power necessary for operating the function of the mobile terminal 3.

  The power information transmission unit 22 transmits power information including information related to the power stored in the battery 21 of the mobile terminal 2 to the connected mobile terminal 3 and the mobile terminal 4. The power information includes, in addition to power, a battery capacity that is the maximum power that the battery 21 can store, a power amount that indicates the current power amount, and a remaining power ratio that indicates a ratio of the power amount to the battery capacity. Including. In addition, the power information transmission part 22 transmits the identification information of the own portable terminal 2 together, when transmitting power information.

  The power information receiving unit 23 receives the respective power information from the connected mobile terminal 3 and mobile terminal 4. When the power information receiving unit 23 receives the power information, the power information receiving unit 23 receives both the identification information of the portable terminal 3 and the portable terminal 4 that transmitted the power information. Thereby, the power information of the connected mobile terminal 3 and mobile terminal 4 can be managed individually.

  The target remaining power amount calculation unit 24 has the maximum remaining power ratio of the own mobile terminal 2 among the connected mobile terminals based on the power information of the own mobile terminal 2 and the power information received by the power information receiving unit 23. Judge that. Next, the target remaining power amount calculation unit 24 calculates the target remaining power amount of the own mobile terminal 2 and the connected mobile terminal 3 and mobile terminal 4 based on the power information received by the power information receiving unit 23. The target remaining power amount is a target value as to how much the power amount of the mobile terminal is set by passing power between the connected mobile terminals. The target remaining power amount may be set as the target remaining power ratio. The target remaining power ratio is a target value indicating how much value the remaining power ratio of the mobile terminal is set by passing power between the connected mobile terminals. In the present embodiment, the target remaining power ratio is used as the target remaining power amount. In the following description, the target remaining power ratio is used as the target remaining power amount. However, instead of the target remaining power ratio, the target remaining power amount indicated by the definition of the target remaining power amount may be used.

  For example, the target remaining power amount calculation unit 24 may calculate an average value of the remaining power ratios of the mobile terminal 2 and the connected mobile terminals 3 and 4 as the target remaining power ratio. More specifically, when the remaining power ratios of the mobile terminal 2, the mobile terminal 3, and the mobile terminal 4 before being connected to each other are 60%, 50%, and 10%, respectively, the target remaining power amount calculation unit 24 Calculates 40%, which is an average value of 60%, 50%, and 10%, and sets the calculated 40% as the target remaining power ratio.

  The calculation method of the target remaining power ratio is not limited to the above calculation method. For example, the target remaining power amount calculation unit 24 sets the target remaining power ratio of one specific mobile terminal or a specific plurality of mobile terminals to 100%. Alternatively, the target remaining power ratio of one specific mobile terminal or a specific plurality of mobile terminals may be calculated as 0%.

  The target remaining power amount transmitting unit 25 transmits the target remaining power ratio calculated by the target remaining power amount calculating unit 24 to the connected mobile terminal 3 and mobile terminal 4.

  The power supply target selection unit 26 is based on the power information received by the power information reception unit 23 and the target remaining power ratio calculated by the target remaining power amount calculation unit 24, and is a power supply destination mobile terminal that is the power supply destination of the own mobile terminal 2. Select. The power supply target selection unit 26 is, for example, one or both of the portable terminal 3 and the portable terminal 4 in which the remaining power ratio included in the power information is smaller than the target remaining power ratio among the connected portable terminals 3 and 4. Is selected as the power supply destination portable terminal. More specifically, for example, the remaining power ratios of the mobile terminal 2, the mobile terminal 3, and the mobile terminal 4 before being connected to each other are 60%, 50%, and 10%, respectively, and the target remaining power amount calculation unit 24 However, when the target remaining power ratio is calculated as 40%, the power supply target selection unit 26 selects the mobile terminal 4 having the remaining power ratio of 10% as the power supply destination mobile terminal.

  Based on the power history of the mobile terminal 2, the required remaining power calculation unit 27 calculates the required remaining power that is the minimum required remaining power at the present time. The power history is, for example, the power consumption speed of the mobile terminal at the date, day of the week, and time, charging timing, and the like. The required remaining power amount calculation unit 27 may calculate a required remaining power ratio that is a minimum required remaining power ratio at the present time based on the power history of the mobile terminal 2 itself. In the present embodiment, the required remaining power ratio is used as the required remaining power amount. In the following description, the required remaining power ratio is used as the required remaining power amount, but the required remaining power amount may be used instead of the required remaining power ratio.

  For example, the required remaining power calculation unit 27 calculates a required remaining power ratio for preventing power from being consumed until the next charging is performed based on the above-described power history. Specifically, for example, it is necessary if the remaining power ratio per hour is reduced by 10% in the future based on the power history and charging at home after 5 hours is predicted by the required remaining power calculation unit 27. The remaining power calculation unit 27 calculates 50% as the required remaining power ratio.

  The power supply unit 28 supplies power to the power supply destination mobile terminal selected by the power supply target selection unit 26 based on the target remaining power ratio calculated by the target remaining power amount calculation unit 24. For example, the power supply unit 28 may supply power to the power supply destination portable terminal selected by the power supply target selection unit 26 until the target remaining power ratio calculated by the target remaining power amount calculation unit 24 is reached. More specifically, for example, the remaining power ratios of the mobile terminal 2, the mobile terminal 3, and the mobile terminal 4 before being connected to each other are 60%, 50%, and 10%, respectively, and the target remaining power amount calculation unit 24 However, when the target remaining power ratio is calculated as 40% and the power supply target selection unit 26 selects the portable terminal 4 with the remaining power ratio of 10% as the power supply destination mobile terminal, the power supply unit 28 is the power supply destination mobile terminal. Power is supplied to the portable terminal 4 having a remaining power ratio of 10% until the remaining power ratio of the power supply destination portable terminal reaches 40%, which is the target remaining power ratio.

  In addition, the power supply unit 28 supplies power to the connected mobile terminal based on the required remaining power ratio calculated by the required remaining power amount calculation unit 27. For example, the power supply unit 28 supplies power to the connected mobile terminal until the required remaining power ratio calculated by the required remaining power amount calculation unit 27 is reached. When the required remaining power ratio calculated by the required remaining power amount calculation unit 27 is larger than the target remaining power ratio calculated by the target remaining power amount calculation unit 24, the power supply unit 28 gives priority to the required remaining power ratio. Then, power is supplied to the connected mobile terminal until the required remaining power ratio is reached, and when the required remaining power ratio is reached, the power supply is stopped. More specifically, for example, the remaining power ratios of the mobile terminal 2, the mobile terminal 3, and the mobile terminal 4 before being connected to each other are 60%, 50%, and 10%, respectively, and the target remaining power amount calculation unit 24 However, the target remaining power ratio is calculated as 40%, the power supply target selection unit 26 selects the portable terminal 4 with the remaining power ratio of 10% as the power supply destination portable terminal, and the required remaining power amount calculation unit 27 calculates the necessary remaining power. When 50% is calculated as the ratio, the power supply unit 28 sets the remaining power ratio of the portable terminal 2 to 50%, which is the required remaining power ratio, with respect to the portable terminal 4 having a remaining power ratio of 10%, which is a power supply destination portable terminal. In other words, the remaining power ratio of 10% is supplied (assuming that the remaining power ratio of the power supply destination portable terminal does not reach 40% even if the remaining power ratio of 10% is supplied).

  In addition, when the required remaining power ratio calculated by the required remaining power calculation unit 27 is larger than the target remaining power ratio calculated by the target remaining power calculation unit 24, the power supply unit 28 gives priority to the target remaining power ratio. Then, power may be supplied to the connected mobile terminal until the target remaining power ratio is reached. When the power supply unit 28 performs power supply with priority on the required remaining power ratio, power can be supplied to the connected mobile terminal while securing the required power in the mobile terminal 2 itself. Further, when the power supply unit 28 performs power supply with priority on the target remaining power ratio, power can be supplied to the connected mobile terminal based on the initial target remaining power amount.

  Next, each functional block of the mobile terminal 3 will be described. In addition, about the functional block of the name similar to the functional block of the portable terminal 2, since a function is the same, detailed description is abbreviate | omitted.

  The power information transmitting unit 32 transmits the power information of the own mobile terminal 3 to the connected mobile terminal 2 and mobile terminal 4. The power information receiving unit 33 receives power information from the connected mobile terminal 2 and mobile terminal 4. The target remaining power receiving unit 34 receives the target remaining power ratio from the connected mobile terminal 2.

  Based on the target remaining power ratio received by the target remaining power amount receiving unit 34, the power feeding determining unit 35 determines whether the power feeding side is for feeding power to another mobile terminal to which the mobile terminal is connected. For example, when the remaining power ratio of the own mobile terminal 3 is larger than the target remaining power ratio, the power supply determination unit 35 determines that the own mobile terminal 3 itself is the power supply side. On the other hand, when the remaining power ratio of the own mobile terminal 3 is smaller than the target remaining power ratio, the power supply determination unit 35 may determine that the own mobile terminal 3 itself is the charging side.

  More specifically, for example, the remaining power ratios of the portable terminal 2, the portable terminal 3, and the portable terminal 4 before being connected to each other are 60%, 50%, and 10%, respectively, and the target remaining power amount receiving unit 34 When the target remaining power ratio 40% is received, the power supply determination unit 35 determines that the mobile terminal 3 is the power supply side. Further, for example, the remaining power ratios of the mobile terminal 2, the mobile terminal 3, and the mobile terminal 4 before being connected to each other are 60%, 30%, and 10%, respectively, and the target remaining power reception unit 34 receives the target remaining power. When the ratio 40% is received, the power supply determination unit 35 determines that the portable terminal 3 is the charging side.

  When the power supply determination unit 35 determines that the mobile terminal is on the power supply side, the power supply target selection unit 36 receives the power information received by the power information reception unit 33 and the target remaining power received by the target remaining power reception unit 34. Based on the ratio, the power supply destination mobile terminal that is the power supply destination of the mobile terminal is selected from the connected mobile terminals. The power supply target selection unit 36 selects, for example, a mobile terminal having a remaining power ratio smaller than the target remaining power ratio among the connected mobile terminals as a power supply destination mobile terminal.

  More specifically, for example, the remaining power ratios of the portable terminal 2, the portable terminal 3, and the portable terminal 4 before being connected to each other are 60%, 50%, and 10%, respectively, and the target remaining power amount receiving unit 34 Receives the target remaining power ratio 40%, and when the power supply determination unit 35 determines that the mobile terminal 3 is the power supply side, the power supply target selection unit 36 selects the mobile terminal 4 as the power supply destination mobile terminal.

  The required remaining power amount calculation unit 37 calculates a required remaining power ratio that is the minimum required remaining power ratio at the present time based on the power history of the mobile terminal 3 itself.

  The power supply unit 38 supplies power to the power supply destination mobile terminal selected by the power supply target selection unit 36 based on the target remaining power ratio received by the target remaining power amount receiving unit 34. The power supply unit 38 supplies power based on the required remaining power ratio calculated by the required remaining power amount calculation unit 37. In addition, when the required remaining power ratio calculated by the required remaining power amount calculating unit 37 is larger than the target remaining power ratio received by the target remaining power amount receiving unit 34, the power supply unit 38 gives priority to the necessary remaining power ratio. Then, power is supplied to the connected mobile terminal until the required remaining power ratio is reached, and when the required remaining power ratio is reached, the power supply is stopped. Alternatively, when the required remaining power ratio calculated by the required remaining power calculating unit 37 is larger than the target remaining power ratio received by the target remaining power receiving unit 34, the power supply unit 38 gives priority to the target remaining power ratio. Then, power may be supplied to the connected mobile terminal until the target remaining power ratio is reached.

  When the power supply unit 38 performs power supply with priority on the required remaining power ratio, power can be supplied to the connected mobile terminal while securing the required power in the mobile terminal 3 itself. Further, when the power supply unit 38 supplies power with priority on the target remaining power ratio, it is possible to supply power to the connected mobile terminal based on the initial target remaining power amount.

  The charging unit 39 performs charging from the connected mobile terminal.
