Abstract: A state-of-charge (SOC) indication method includes: determining estimated values of a SOC of a battery cell according to at least information regarding a characteristics measurement of the battery cell; performing a smooth and monotonic processing on the estimated values of the SOC to process unusual change in the estimated values, so as to generate processed values of the SOC; remapping the processed values of the SOC according to a remapping threshold setting to obtain remapped values of the SOC; and indicating the SOC of the battery cell with the remapped values.

Abstract: A method capable of accurately estimating a power percentage of a battery includes: performing a first fuel gauge operation to measure a power percentage of the battery to generate first information; performing a second fuel gauge operation to measure the power percentage of the battery to generate second information, the first fuel gauge operation being different from the second fuel gauge operation; and, dynamically determining one among at least the first percentage and the second percentage as the power percentage of the battery.
