Abstract
An electronic device is provided. The electronic device includes a battery, a power supply circuit electrically connected to the battery and configured to charge the battery, a processor controlling the power supply circuit, wherein the processor, when a cable of a charger for charging is connected to the power supply circuit, determines the charging type of the charger through the cable, when the charging type has been determined, determines the target resistance value of the charger, and charges the battery by using a charging mode corresponding to the determined charging type and target resistance value.
Claims19
An electronic device comprising:
- a battery;
- a power supply circuit electrically connected to the battery and configured to charge the battery;
- memory storing one or more computer programs;
- and
- one or more processors communicatively coupled to the power supply circuit and the memory,
- wherein the one or more computer programs include computer-executable instructions that, when executed by the one or more processors individually or collectively, cause the electronic device to:
- when a cable of a charger for charging is connected to the power supply circuit, determine a charging type of the charger through the cable,
- when the charging type of the charger is determined, determine a target resistance value of the charger based on a resistance value of the charger measured through a configuration channel (CC) pin of the cable by a CC power delivery (PD) circuit of the power supply circuit,
- determine whether the target resistance value corresponds to a preset resistance value,
- based on the target resistance value corresponding to the preset resistance value, determine whether the charger is capable of supporting charging power of a preset value or more,
- based on the charging type, the target resistance value, and a result of the determining of whether the charger is capable of supporting charging power of the preset value or more, determine a charging mode, and
- charge the battery by using the charging mode.
