ELECTRONIC DEVICE COMPRISING A PLURALITY OF BATTERIES AND METHOD FOR PROTECTING THE BATTERIES IN THE SAME

A method for protecting a battery of an electronic device including a plurality of batteries, includes: measuring a total current (I) value output from a charging module while the plurality of batteries are charged via the charging module; detecting a first current (I) value output to a first battery via a current limiter; calculating a difference between the total current (I) value and the first current (I) value to estimate a second current (I) value transferred to a second battery without passing through any current limiter, where the first battery and the second battery are included in the plurality of batteries; and controlling, based on the estimated second current (I) value, a current of the second battery, which has the second current (I) value, by controlling opening/closing of a switching module included in a protection circuit module of the second battery.
