Abstract
An electronic device comprises a power receiving unit and a control unit. In a first mode in which the power receiving unit receives power from a first battery and does not receive power from a second battery, the control unit calculates a first operable time based on a plurality of information relating to the first battery acquired from the first battery, and calculates a second operable time based on information other than information of a discharge current of the second battery among a plurality of information relating to the second battery acquired from the second battery and the information of the discharge current of the first battery acquired from the first battery.
Claims17
An electronic device comprising:
- a CPU;
- and
- a memory storing a program which, when executed by the CPU, causes the electronic device to function as the following units:
- a power receiving unit that receives power from a first battery and receives power from a second battery;
- an acquisition unit that acquires from the first battery a plurality of information relating to the first battery, including information of a discharge current of the first battery and acquires from the second battery a plurality of information relating to the second battery, including information of a discharge current of the second battery;
- and
- a control unit that calculates a first operable time for which the electronic device can operate using power from the first battery based on the plurality of information relating to the first battery acquired by the acquisition unit and calculates a second operable time for which the electronic device can operate using power from the second battery based on the plurality of information relating to the second battery acquired by the acquisition unit,
- wherein in a first mode in which the power receiving unit receives power from the first battery and does not receive power from the second battery, the control unit calculates the first operable time based on the plurality of information relating to the first battery acquired from the first battery, and calculates the second operable time based on information other than the information of the discharge current of the second battery among the plurality of information relating to the second battery acquired from the second battery and the information of the discharge current of the first battery acquired from the first battery.
An electronic device comprising:
- a CPU;
- and
- a memory storing a program which, when executed by the CPU, causes the electronic device to function as the following units:
- a power receiving unit that receives power from a first battery and receives power from a second battery;
- an acquisition unit that acquires from the first battery a plurality of information relating to the first battery, including information of a discharge current of the first battery and acquires from the second battery a plurality of information relating to the second battery, including information of a discharge current of the second battery;
- and
- a control unit that calculates a first operable time for which the electronic device can operate using power from the first battery based on the plurality of information relating to the first battery acquired by the acquisition unit and calculates a second operable time for which the electronic device can operate using power from the second battery based on the plurality of information relating to the second battery acquired by the acquisition unit,
- wherein in a case that the control unit performs a predetermined control such that the power receiving unit receives power from the first battery and does not receive power from the second battery, the control unit calculates the first operable time based on the plurality of information relating to the first battery, and calculates the second operable time based on a predetermined information that is acquired from the first battery and cannot be acquired from the second battery in the predetermined control among the plurality of information relating to the second battery and information other than the predetermined information among the plurality of information relating to the second battery.
A method of controlling an electronic device having a power receiving unit that receives power from a first battery and receives power from a second battery, the method comprising:
- acquiring a plurality of information relating to the first battery, including information of a discharge current of the first battery from the first battery and a plurality of information relating to the second battery, including information of a discharge current of the second battery from the second batter;
- and
- performing control so as to calculate a first operable time for which the electronic device can operate using power from the first battery based on the plurality of information relating to the first battery calculate a second operable time for which the electronic device can operate using power from the second battery based on the plurality of information relating to the second battery,
- wherein in a first mode in which the electronic device receives power from the first battery and does not receive power from the second battery, the control calculates the first operable time based on the plurality of information relating to the first battery acquired from the first battery, and calculates the second operable time based on information other than the information of the discharge current of the second battery among the plurality of information relating to the second battery acquired from the second battery and the information of the discharge current of the first battery acquired from the first battery.
