Abstract
An electronic device includes a first connection unit, a second connection unit, and a control unit. The control unit determines whether a first external device is connected to the first connection unit, and controls the electronic device to prevent charging of a battery connected to the first external device with power supplied from a second external device connected to the second connection unit, in a case where the first external device is connected to the first connection unit.
Claims18
An electronic device comprising:
- a first connection unit connectable to a first external device;
- a second connection unit connectable to a second external device;
- and
- a control unit that determines whether the first external device is connected to the first connection unit,
- wherein the control unit prevents charging of a first battery connected to the first external device with power supplied from the second external device connected to the second connection unit, in a case where the first external device is connected to the first connection unit, the second external device is connected to the second connection unit, and a second battery is not connected to the first connection unit, and
- wherein the control unit allows charging of the second battery connected to the first connection unit with power supplied from the second external device connected to the second connection unit, in a case where the first external device is not connected to the first connection unit, the second external device is connected to the second connection unit, and the second battery is connected to the first connection unit.
A method of controlling an electronic device including a first connection unit connectable to a first external device and a second connection unit connectable to a second external device, the method comprising:
- determining whether the first external device is connected to the first connection unit;
- preventing charging of a first battery connected to the first external device with power supplied from the second external device connected to the second connection unit, in a case where the first external device is connected to the first connection unit, the second external device is connected to the second connection unit, and a second battery is not connected to the first connection unit;
- and
- allowing charging of the second battery connected to the first connection unit with power supplied from the second external device connected to the second connection unit, in a case where the first external device is not connected to the first connection unit, the second external device is connected to the second connection unit, and the second battery is connected to the first connection unit.
A non-transitory storage medium that stores a program for causing a computer to perform a method of controlling an electronic device including a first connection unit connectable to a first external device and a second connection unit connectable to a second external device, the method comprising:
- determining whether the first external device is connected to the first connection unit;
- preventing charging of a first battery connected to the first external device with power supplied from the second external device connected to the second connection unit, in a case where the first external device is connected to the first connection unit, the second external device is connected to the second connection unit, and a second battery is not connected to the first connection unit;
- and
- allowing charging of the second battery connected to the first connection unit with power supplied from the second external device connected to the second connection unit, in a case where the first external device is not connected to the first connection unit, the second external device is connected to the second connection unit, and the second battery is connected to the first connection unit.
