METHOD AND APPARATUS FOR ADJUSTING VOLTAGE THRESHOLD FOR BATTERY BY MEASURING INTERNAL RESISTANCE OF BATTERY, AND CORRESPONDING METHOD AND SENSOR CIRCUIT FOR MEASURING INTERNAL RESISTANCE OF BATTERY

摘要

A method for adjusting a voltage threshold for a battery being connected to a portable device includes: dynamically measuring an internal resistance of the battery; and dynamically adjusting the voltage threshold according to the internal resistance of the battery and a current flowing through the battery.
