ELECTRONIC DEVICE HAVING STRUCTURE TO MINIMIZE POWER LOSS DURING BATTERY CHARGING AND DISCHARGING

In various embodiments, an electronic device may include a battery pack including a charging terminal, a discharging terminal, and at least one battery cell. A first substrate is connected to the charging terminal and a second substrate is connected to the discharging terminal. An external connector is mounted on the first substrate and connected to an external power supply device. A first internal connector is mounted on the first substrate and connected to the charging terminal. A second internal connector is mounted on the second substrate and connected to the discharging terminal. A charging circuit is mounted on the first substrate and configured to receive a first power signal from the power supply device through the external connector, to adjust a current and/or voltage of the received first power signal, and to output the adjusted first power signal to the charging terminal through the first internal connector. A system of the electronic device is mounted on the second substrate. A power management circuit is mounted on the second substrate and configured to receive a second power signal for the system to operate from the discharging terminal through a second internal connector, and to supply the received second power signal to the system.
