FIG. 7 illustrates a flowchart of a method for setting an upper current limit of an electronic device including a rollable display (e.g., at least one processor 530 of FIG. 5 ) according to various embodiments of the present disclosure.

Referring to FIG. 7, electronic devices according to various embodiments may set an upper current limit by dividing temperature sections as follows for efficient battery charging.

The electronic device according to various embodiments may detect that the electronic device is in a charging state when a signal associated with receiving power from an external source is obtained from the wireless charging IC in operation 710. In one embodiment, the electronic device may detect wireless charging of the electronic device when it obtains a signal associated with wirelessly receiving power from the outside through an antenna from the wireless charging IC.

Additionally, as at least part of the operation of setting the upper current limit (e.g., operation 650 of FIG. 6), the electronic device divides the internal temperature of the electronic device or the temperature of the battery into a plurality of temperature sections in operation 730, and in operation 750, The upper current limit can be set based on the acquired signal related to the internal temperature of the electronic device or the temperature of the battery and the arrangement state between the first and second housings.

Specifically, the electronic device according to various embodiments is disposed between the first housing and the second housing in operation 740 when the internal temperature of the electronic device or the temperature of the battery is in the room temperature range (10 to 30 ° C.) in operation 734. , and if the detected placement state is the second state (extended state), the upper current limit is set in operation 752. It can be set to . here, is the maximum charging current that can be supported by the electronic device, and may be set differently depending on the type and/or capacity of the battery, the pattern and/or efficiency of the wireless charging antenna, etc.

In addition, the electronic device according to various embodiments sets the upper current limit in operation 753 when the detected arrangement state between the first housing and the second housing is the first state (reduced state). It can be set to .

Qout is the amount of heat transfer in the expanded state between the first housing and the second housing, and Qin is the amount of heat transfer in the collapsed state between the first housing and the second housing.

Therefore, depending on the arrangement between the first housing and the second housing, the upper limit of the current for limiting the size of the current received from the wireless charging IC or the current charging the battery is differentiated to reduce the size of the first housing and the second housing. Charging can be carried out efficiently without entering heat limit control.

The electronic device according to various embodiments may set the upper current limit even in the collapsed state of the first and second housings in operation 752 when the electronic device or battery is in a low temperature range (0 to 10°C) in operation 732. It can be set to . If the internal temperature of the electronic device or the temperature of the battery is relatively low, the temperature of the electronic device or battery is relatively low even in the collapsed state of the first and second housings, so even if the charging current is relatively increased and the electronic device is charged Alternatively, it may take a long time for the battery temperature to rise.

It can be set to . If the internal temperature of the electronic device or the temperature of the battery is in the high temperature range, the temperature of the electronic device or battery has already risen high, so when charging the electronic device or battery with a high charging current, heat limit control is entered within a short period of time. can do. Therefore, the upper current limit is set regardless of the expanded or collapsed state of the first housing and the second housing. It can be set to . Even in this case, when the internal temperature of the electronic device or the temperature of the battery decreases and leaves the high temperature range and enters the room temperature range, the upper current limit is set in the expanded state of the first and second housings. can be increased.

The operation of providing a notification suggesting a change to the extended state of 680 can be omitted, and the driving signal can be transmitted to the driving module.

For example, if the acquired signal associated with receiving power from the outside is a signal receiving power wirelessly through an antenna, the electronic device automatically generates a driving signal that changes the arrangement state between the first housing and the second housing. It can be transmitted to the drive module. Here, the driving signal may be a signal that drives the arrangement state between the first housing and the second housing to change to a second state in which the second housing is pulled out from the inside of the first housing.
