Abstract: Various embodiments of the disclosure relate to an apparatus and method for preventing overcharging of a battery. In this case, the electronic device includes a battery, at least one processor, and a memory electrically coupled to the at least one processor. The memory may store instructions, when executed, allowing the at least one processor to set a charge safety time corresponding to an external device upon connection with the external power device, charge the battery, based at least in part on power of the external power device, and update the charge safety time, based on a change of at least one of charging current and discharging current of the battery. Other embodiments may also be possible.

Abstract: A method of controlling charging of a plurality of batteries and an electronic device to which the same is applied are provided. The electronic device includes a housing, a plurality of batteries arranged in the housing, a power management module that controls the plurality of batteries, a plurality of current limiting ICs that limits a maximum intensity of a current flowing into each of the plurality of batteries, and at least one processor operationally connected to the plurality of batteries, the power management module and the plurality of current limiting ICs. The at least one processor may set a total charging current output from the power management module, set an individual charging current flowing into each of the plurality of batteries in proportion to a total capacity of each of the plurality of batteries, and recalculate the individual charging currents when the total charging current changes.
