Abstract: An apparatus and a method of controlling charging of a plurality of batteries connected in parallel in an electronic device are provided. The electronic device includes a charging circuit, a first battery configured to be arranged on a first electrical path connected from the charging circuit to the ground, a second battery configured to be arranged in parallel with the first battery on a second electrical path branched between the charging circuit on the first electrical path and the first battery and connected to the ground, a sensing circuit configured to identify a voltage of the second battery through a fourth electrical path branched on the second electrical path, and a processor operatively connected to the sensing circuit and the charging circuit, the charging circuit identifies a voltage of the first battery through a third electrical path branched on the first electrical path, receives a current control signal based on the voltage of the second battery through the processor, and controls a magnitude of a current supplied to the first battery or the second battery based on the current control signal.

Abstract: An electronic device is provided. The electronic device includes a housing, a first battery and a second battery arranged in the housing, a power management module, a first temperature sensor, a second temperature sensor, a first current limiting integrated circuit (IC) configured to limit a maximum intensity of a first current flowing into the first battery, a second current limiting IC configured to limit a maximum intensity of a second current flowing into the second battery, and a processor. The processor may determine whether the first temperature or the second temperature is outside a specified temperature range and, when the first temperature is outside of the specified temperature range, control the first current limiting IC to reduce a magnitude of the first current.
