According to one embodiment, the first battery connector (831) of the second battery (372) can form a path to supply the voltage converted by the first power conversion circuit (811) to the second battery (372) when an external device that does not support high-speed charging, such as a general charger that cannot vary the output current and output voltage, is connected to the connector (307) of the electronic device (101).

For example, a battery protection circuit included in the second battery (372) (e.g., the battery protection circuit (1600) of FIG. 14) may include a current blocking element to prevent the supply of power (e.g., reverse bypass and / or reverse boosting) flowing through the second battery connector (832) from the current discharged from the second battery (372). The second battery (372) protection circuit included in the second battery (372) will be described in detail later with reference to FIG. 14 and FIG. 15. According to one embodiment, a discharge path supplying power from the second battery (372) to a load circuit (e.g., a system) placed in the second housing (320) may be formed through the first battery connector (831) of the second battery (372).

[0133] According to one embodiment, when a first external device (e.g., a fast charger) configured to supply a maximum first power is connected through a connector (e.g., connector (307) of FIG. 8), the electronic device (101) can convert power supplied from the first external device using a DC IC (813) and a second power conversion circuit (823).

[0134] According to one embodiment, when a high-speed charger capable of varying output current and output voltage is connected to an electronic device (101), a first charging path (1211) for charging a first battery (371) may be as follows.
