Abstract
An electronic device is provided. The electronic device includes a voltage divider circuit, a first battery electrically connected to a first point of the voltage divider circuit, and a second battery connected in series to the first battery. A second point different from the first point of the voltage divider circuit is electrically connected from a first node on an electric path through which the first battery and the second battery are electrically connected.
Claims16
An electronic device comprising:
- a voltage divider circuit;
- a first battery electrically connected to a first point of the voltage divider circuit;
- a second battery connected in series to the first battery;
- and at least one processor, wherein a second point different from the first point of the voltage divider circuit is electrically connected from a first node on a first electric path through which the first battery and the second battery are electrically connected, wherein the at least one processor is configured to:
- control the voltage divider circuit so as to be turned on in case that a voltage difference between the first battery and the second battery satisfies first reference voltage, and control the voltage divider circuit so as to be turned off in case that the voltage difference between the first battery and the second battery does not satisfy the first reference voltage, and
- wherein the at least one processor is further configured to:
- control at least two of multiple sub-divider circuits included in the voltage divider circuit so as to be turned on, in case that the voltage difference between the first battery and the second battery satisfies a second reference voltage in a state in which the voltage divider circuit is turned on;
- and
- adjust a turning-on cycle of the voltage divider circuit in case that the voltage difference between the first battery and the second battery satisfies a third reference voltage in a state in which at least a part of the voltage divider circuit is turned on.
