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.

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.
