METHOD OF CONTROLLING CHARGING OF PLURALITY OF BATTERIES AND ELECTRONIC DEVICE TO WHICH THE METHOD IS APPLIED

Document Type and Number:

WIPO Patent Application WO/2020/159065

Kind Code:

A1

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.
