Abstract
An electronic device includes a rechargeable battery, a first battery charger that charges the rechargeable battery by power supplied from an external power supply, a second battery charger that charges the rechargeable battery by a solar panel, and a processor that charges the rechargeable battery to a first voltage by the first battery charger, and charges the rechargeable battery to a second voltage lower than the first voltage by the second battery charger.
Claims9
An electronic device comprising:
- a rechargeable battery;
- a first battery charger that charges the rechargeable battery by power supplied from an external power supply;
- a second battery charger that charges the rechargeable battery by a solar panel;
- and
- a processor which, in operation, stops charging by the first battery charger when the rechargeable battery is charged such that a terminal voltage of the rechargeable battery is a first voltage while being charged by the first battery charger, and stops charging by the second battery charger when the rechargeable battery is charged such that the terminal voltage of the rechargeable battery is a second voltage lower than the first voltage while being charged by the second battery charger.
A battery charging method performed by an electronic device, wherein
- the electronic device includes a rechargeable battery, a first battery charger that charges the rechargeable battery by power supplied from an external power supply, a second battery charger that charges the rechargeable battery by a solar panel, and a processor, and
- the battery charging method comprises:
- stopping charging by the first battery charger when the rechargeable battery is charged such that a terminal voltage of the rechargeable battery is a first voltage while being charged by the first battery charger;
- and
- stopping charging by the second battery charger when the rechargeable battery is charged such that the terminal voltage of the rechargeable battery is a second voltage lower than the first voltage while being charged by the second battery charger.
A non-transitory computer-readable storage medium storing a program that, when executed by a processor of an electronic device including a rechargeable battery, a first battery charger that charges the rechargeable battery by power supplied from an external power supply, and a second battery charger that charges the rechargeable battery by a solar panel causes the processor to:
- stop charging by the first battery charger when the rechargeable battery is charged such that a terminal voltage of the rechargeable battery is a first voltage while being charged by the first battery charger;
- and
- stop charging by the second battery charger when the rechargeable battery is charged such that the terminal voltage of the rechargeable battery is a second voltage lower than the first voltage while being charged by the second battery charger.
