Abstract
An electronic apparatus includes a secondary battery, a first power feeder, a second power feeder, and a processor. The first power feeder feeds power to the secondary battery. The second power feeder feeds power to the secondary battery at a current larger than a current fed by the first power feeder. The processor selects an operation mode of the electronic apparatus based on different reference values selected based on whether the first power feeder is feeding power to the secondary battery or the second power feeder is feeding power to the secondary battery.
Claims20
An electronic apparatus comprising:
- a secondary battery;
- a first power feeder that feeds power to the secondary battery;
- a second power feeder that feeds power to the secondary battery at a current larger than a current fed by the first power feeder;
- and
- a processor configured to:
- detect a voltage of the secondary battery;
- in response to the first feeder feeding power to the secondary battery, select an operation mode from a plurality of operation modes based on a comparison of the detected voltage with a first reference value;
- and
- in response to the second feeder feeding power to the secondary battery, select the operation mode from the plurality of operation modes based on a comparison of the detected voltage with a second reference value, the second reference value being different from the first reference value.
A power feeding control method comprising:
- detecting a voltage of a secondary battery;
- in response to a first feeder feeding power to the secondary battery, selecting an operation mode from a plurality of operation modes based on a comparison of the detected voltage with a first reference value;
- and
- in response to a second feeder feeding power to the secondary battery, selecting the operation mode from the plurality of operation modes based on a comparison of the detected voltage with a second reference value,
- wherein the second reference value is different from the first reference value, and
- wherein the second power feeder feeds power to the secondary battery at a current larger than a current fed by the first power feeder.
A non-transitory recording medium that stores a program executable by a computer of an electronic apparatus to control the computer to:
- detect a voltage of a secondary battery;
- in response to a first feeder feeding power to the secondary battery, select an operation mode from a plurality of operation modes based on a comparison of the detected voltage with a first reference value;
- and
- in response to a second feeder feeding power to the secondary battery, select the operation mode from the plurality of operation modes based on a comparison of the detected voltage with a second reference value,
- wherein the second reference value is different from the first reference value, and
- wherein the second power feeder feeds power to the secondary battery at a current larger than a current fed by the first power feeder.
