Description

How to control electronic devices and charging

[0001] The present disclosure relates to an electronic device and a method for controlling charging.

[0002] Miniaturized electronic devices with wireless charging capabilities (e.g., earbuds, a cradle containing earbuds, a watch, or a ring) may, due to space limitations, include a metal structure (e.g., a metal hinge) in proximity to the coil that wirelessly receives power.

[0003] When an electronic device wirelessly receives power from an external electronic device (e.g., a wireless charging pad) to perform charging, a metal structure of the electronic device may be positioned within an operating area of ​​a power transmitting coil of the external electronic device.

[0004] When an external electronic device detects a metal structure, it may determine that it is a foreign object detected (FOD) situation and stop transmitting power to the electronic device. However, if the metal structure does not exceed a threshold for determining a foreign object detected situation, the external electronic device may continue to transmit power to the electronic device. In this case, the electronic device may generate heat not only from charging due to the power received from the external electronic device, but also from the metal structure. In addition, for the sake of user safety, the electronic device may repeatedly enter and exit heat control mode more frequently, which may prolong the time it takes to fully charge the battery included in the electronic device.

[0015] The instructions of the present disclosure, when individually or collectively executed by the at least one processor, may cause the electronic device to use the at least one sensor to determine a temperature value, or a slope of a temperature change, of the electronic device while charging the battery according to the second mode.

[0016] The instructions of the present disclosure, when individually or collectively executed by the at least one processor, may cause the electronic device to charge the battery according to the first mode if the slope is greater than a first reference value or if the temperature value is greater than or equal to a first designated temperature.

[0017] The charging control method of the electronic device of the present disclosure may include an operation of performing a charging operation by receiving power from an external electronic device.

[0018] A charging control method of an electronic device of the present disclosure may include an operation of checking and storing a temperature of the electronic device using at least one sensor.

The external electronic device (202) can determine whether the mounted electronic device (201) is a power-receiving device or a foreign object based on the authentication and / or electromagnetic signal, and can transmit power to the electronic device (201).

[0112] Table 1 is a table comparing the full charge time of an electronic device (201) to which a charge control operation according to an embodiment of the present disclosure is applied and a general electronic device.

Therefore, the general electronic device has a problem in that it takes a long time to charge the battery of the electronic device because it continues to receive power even in a misalignment state and performs an operation of blocking the charge operation until the temperature goes down if a heat generation state persists. However, the electronic device (201) to which a charge control operation according to an embodiment of the present disclosure is applied sets at least one of a charge current, a charge voltage, or a charge cycle (e.g., a second charge current, a second charge voltage, a second charge cycle, or a second charge time width) so that the temperature does not rise in a misalignment state, and charges the battery (215), thereby quickly charging the battery (215) while suppressing heat generation.

The first charging cycle may be longer than the second charging cycle. The first charging time span may be shorter than the second charging time span.
