Abstract
An electronic timepiece 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 determines remaining power of the secondary battery based on different references that are a reference of when the first power feeder is feeding the power to the secondary battery and a reference of when the second power feeder is feeding the 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;
- when the first power feeder is feeding the power to the secondary battery, determine a remaining power of the secondary battery by comparing the detected voltage with a first reference value;
- and
- when the second power feeder is feeding the power to the secondary battery, determine the remaining power of the secondary battery by comparing the detected voltage with a second reference value that is higher than the first reference value.
A power feeding control method executed by an electronic apparatus that comprises a secondary battery, a first power feeder that feeds power to the secondary battery, and a second power feeder that feeds power to the secondary battery at a current larger than a current fed by the first power feeder, the method comprising:
- detecting a voltage of the secondary battery;
- when the first power feeder is feeding the power to the secondary battery, determining a remaining power of the secondary battery by comparing the detected voltage with a first reference value;
- and
- when the second power feeder is feeding the power to the secondary battery, determining the remaining power of the secondary battery by comparing the detected voltage with a second reference value that is higher than the first reference value.
A non-transitory recording medium storing a program readable by a computer of an electronic apparatus that comprises a secondary battery, a first power feeder that feeds power to the secondary battery, and a second power feeder that feeds the power to the secondary battery at a current larger than a current fed by the first power feeder, the program causing the computer to execute control of functions comprising:
- detecting a voltage of the secondary battery;
- when the first power feeder is feeding the power to the secondary battery, determining a remaining power of the secondary battery by comparing the detected voltage with a first reference value;
- and
- when the second power feeder is feeding the power to the secondary battery, determining the remaining power of the secondary battery by comparing the detected voltage with a second reference value that is higher than the first reference value.
