Definitions
- the present disclosure relates to battery charging of an electronic device based on an internal temperature of the electronic device.
- the electronic device may use a constant current (CC) and constant voltage (CV) charging profile when charging the battery in order to extend the life of the battery and shorten the charging time. For example, when the voltage of the battery is lower than a specified target voltage value, the electronic device converts the current of a power signal output to the battery from a power management circuit (eg, a charging circuit) to a specified current value (hereinafter referred to as a charging current value). Battery charging may be performed in a manner that remains constant.
- the target voltage value may be equal to a voltage difference between a positive (+) pole and a negative (-) pole of the battery when the battery is in a fully charged state.
- Full charge may mean a state of charge (SOC) when the charge amount of the battery reaches 100%, which is a set maximum capacity, without fear of burnout or explosion.
- SOC state of charge
- the electronic device gradually reduces the current of the power signal output from the power management circuit from the charging current value so that the battery voltage is maintained at the target voltage value. Charging can be done in this way. As such, when the current of the power signal output from the power management circuit during battery charging in the CV mode is lowered to a current value for charging completion, the electronic device may determine that the battery is fully charged and complete battery charging.
- the electronic device may perform charging by gradually increasing the voltage of the battery. For example, the electronic device may charge the battery in a manner of constantly maintaining the current of the power signal output from the power management circuit at a first charging current value. When the voltage of the battery rises to the first target voltage value, the electronic device may gradually reduce the current of the power signal output from the power management circuit from the first charging current value. When the current of the power signal output from the power management circuit is lowered to the designated second charging current value, the electronic device charges the battery by maintaining the current of the power signal output from the power management circuit constant at the second charging current value. can do. When the voltage of the battery rises to the second target voltage value, the electronic device may gradually reduce the current of the power signal output from the power management circuit from the second charging current value. When the current of the power signal output from the power management circuit is lowered to a current value for charging completion, the electronic device may complete battery charging.

- the heating control operation may be performed during battery charging in the CC mode. For example, when the internal temperature of the electronic device rises up to a designated first temperature value (eg, thermal trigger temperature value) that triggers a heating control operation, the electronic device converts the current of the power signal output from the power management circuit to the currently set charge A heating control mode in which the current value is lowered to a designated thermal control current value for heat reduction may be performed.
- a designated first temperature value eg, thermal trigger temperature value
- the electronic device While the heating control mode is being performed, if the internal temperature of the electronic device is lowered to the second temperature value (eg, thermal release temperature value) for disabling the designated heating control mode, the electronic device releases the heating control mode and uses the power management circuit The current of the output power signal may be increased again to the charging current value.
- the second temperature value eg, thermal release temperature value

- Various embodiments may provide an electronic device capable of quickly charging a battery by minimizing the number of times of entering a heating control mode.
- an electronic device may include a battery; a power management circuit configured to charge the battery using a power signal wired or wirelessly received from an external power supply; temperature Senser; a processor coupled to the temperature sensor and the power management circuitry; and a memory operatively coupled to the processor.
- the processor When the memory is executed, the processor: While the current value of the power signal for charging the battery is set to the first charging current value, the internal temperature of the electronic device is set to the first temperature value through the temperature sensor.
- the current value of the power signal for charging the battery is set to a heating control current value lower than the first charging current value, and the While the current value of the power signal for battery charging is set to the heating control current value, it is confirmed through the temperature sensor that the internal temperature of the electronic device has decreased to the second temperature value, and the internal temperature of the electronic device is Store instructions for setting the current value of the power signal for charging the battery to a second charging current value lower than the first charging current value but higher than the heating control current value as the temperature decreases to the second temperature value can

- a heating control mode is performed in which a current value of a power signal for charging the battery is lowered from a first charging current value to a heating control current value according to the first temperature value, and the internal temperature of the electronic device is reduced from the first temperature value to the heating control current value.
- the heating control mode is released by increasing the current value of the power signal for charging the battery from the heating control current value to a second charging current value lower than the first charging current value, While the battery is being charged in a CV (constant voltage) mode in which the current value of the power signal for battery charging is gradually lowered as the voltage of the battery reaches the target voltage value, the current value of the power signal for charging the battery When the charge completion current value is lowered to this value, the supply of the power signal to the battery is cut off, thereby storing instructions for completing the battery charge.
