<p><P>PROBLEM TO BE SOLVED: To provide a hybrid battery that allows to accurately calculate a total full charge capacity by calculating a full charge capacity at least at two discharge-voltage levels while sensing a power-supply voltage that is currently discharged. <P>SOLUTION: The hybrid battery is provided with a first power supply 1100, a second power supply 1200, a sensing register 1300 for sensing current information of the first power supply or the second power supply so as to output it, and a fuel gauge circuit 1400 that calculates a first accumulated discharge amount or a second accumulated discharge amount by utilizing the current information from the sensing register so as to calculate a first full charge capacity or a second full charge capacity on the basis of the first accumulated discharge amount or the second accumulated discharge amount when a power-supply voltage of the first power supply or the second power supply reaches a first discharge voltage level or a second discharge voltage level. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
