Electronic device and control method
An electronic device includes a charging unit that charges a battery with power supplied from an external device, and a control unit that controls a communication unit of the electronic device such that a communication interval from a start of charging the battery by the charging unit until a battery voltage exceeds a predetermined threshold is shorter than a communication interval after the battery voltage exceeds the predetermined threshold, in a case where power is received from the external device.
1. An electronic device comprising:
a CPU;
a memory storing a program which, when executed by the CPU, causes the CPU to function as:
a charging unit that charges a battery with power supplied from an external device;
a communication unit that communicates with the external device; and
a control unit that controls the communication unit to perform a predetermined communication for requesting a change of power to be supplied to the electronic device in a case where the battery is being charged by the charging unit,
wherein the control unit controls the communication unit such that an interval of performing the predetermined communication from a start of charging the battery by the charging unit until a battery voltage exceeds a predetermined threshold is shorter than an interval of performing the predetermined communication after the battery voltage exceeds the predetermined threshold, in a case where the battery is being charged by the charging unit.
2. The electronic device according to claim 1 , wherein the program, when executed by the CPU, further causes the CPU to function as a voltage detection unit that detects the battery voltage,
wherein the control unit determines the interval based on a battery voltage detected by the voltage detection unit, and
the control unit controls the communication unit to transmit a power request of a predetermined voltage to the external device in the predetermined communication.
3. The electronic device according to claim 2 , wherein the control unit determines the interval during the charging depending on a gradient of a charging curve when the battery is charged.
4. The electronic device according to claim 2 , wherein the charging unit starts charging the battery with a constant current and then switches to charging with a constant voltage, and
the control unit determines the interval so that the interval in a first period from the start of the charging by the constant current is shorter than the interval in a period after the first period in the charging by the constant current and the interval in the charging with the constant voltage.
5. The electronic device according to claim 2 , wherein the charging unit starts charging the battery with a constant current and then switches to charging with a constant voltage, and
the interval during the charging by the constant current is shorter than the interval during the charging by the constant voltage.
6. An electronic device comprising:
a CPU; and
a memory storing a program which, when executed by the CPU, causes the CPU to function as:
a charging unit that charges a battery with power supplied from an external device;
a communication unit that communicates with the external device; and
a control unit that controls the communication unit to perform a predetermined communication for requesting a change of power to be supplied to the electronic device in a case where the battery is being charged by the charging unit,
wherein the control unit controls the communication unit so that an interval of performing the predetermined communication becomes a predetermined interval, in a case where a change amount of battery voltage exceeds a predetermined value in charging of the battery, and controls the communication unit so that an interval of performing the predetermined communication becomes shorter than the predetermined interval, in a case where the change amount of battery voltage does not exceed the predetermined value in charging of the battery.
7. A method comprising:
charging a battery by power supplied from an external device;
communicating with the external device; and
controlling the communicating to perform a predetermined communication for requesting a change of power to be supplied to the electronic device in a case where the battery is being charged by the charging,
wherein the controlling controls the communicating such that an interval of performing the predetermined communication from a start of charging the battery until the battery voltage exceeds a predetermined threshold is shorter than an interval of performing the predetermined communication after the battery voltage exceeds the predetermined threshold, in a case where the battery is being charged by the charging.
8. A method comprising:
charging a battery by power supplied from an external device;
communicating with the external device;
controlling the communicating to perform a predetermined communication for requesting a change of power to be supplied to the electronic device in a case where the battery is being charged by the charging,
wherein the controlling controls the communicating such that an interval of performing the predetermined communication becomes a predetermined interval, in a case where a change amount of battery voltage exceeds a predetermined value in charging of the battery; and
controlling the communication unit such that an interval of performing the predetermined communication becomes shorter than the predetermined interval, in a case where the change amount of battery voltage does not exceed the predetermined value in charging of the battery.
