APPARATUS AND METHOD FOR GAUGING REMAINDER OF BATTERY

摘要

An apparatus and method for gauging remainder is provided to measure remainder of a battery exactly by adding compensation voltage corresponding to the amount of load current to an output voltage of battery. In an apparatus and method for gauging remainder, a voltage detector(210) detects output voltage of a battery and measure a load current supplied to each load of electronic device from the battery. A voltage compensation unit(220) outputs compensation voltage corresponding to the amount of measured load current. A calculation unit(240) calculates the remainder of the battery corresponding to the add result of the voltage and compensation value after receiving output voltage and the compensation voltage.
