Title:
ELECTRONIC DEVICE COMPRISING PLURALITY OF BATTERIES, AND BATTERY PROTECTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/106869
Kind Code:
A1
Abstract:
An electronic device according to various embodiments comprises: a first battery including a first protection circuit module (PCM); a second battery which is branched from a first node and connected in parallel with the first battery, and includes a second protection circuit module (PCM); a charging module which is connected to the first node and charges the first battery and the second battery by using power input from an external device; a current limiter which is arranged between the first node and the first battery and adjusts the magnitude of a current flowing into the first battery; and a processor electrically connected to the current limiter and the second battery, wherein the processor may be configured to: measure a total current (Itotal) value output from the charging module and a first current (I1) value output from the current limiter to the first battery; estimate a second current (I2) value transmitted to the second battery by calculating a difference between the total current (Itotal) value and the first current (I1) value; and control a current of the second battery by controlling opening and closing of a switching module included in the second PCM on the basis of the second current value.
