<P>PROBLEM TO BE SOLVED: To solve such a problem that since the internal resistance of a battery has such characteristics that the internal resistance transiently rises due to the continuous repetition of charging/discharging in a long time in a lithium battery, voltage fluctuation due to the internal resistance when charging/discharging becomes large, and it exceeds the possible fluctuation voltage width of the battery, and it is necessary to sharply restrict charging/discharging currents. <P>SOLUTION: With respect to the charging/discharging currents of a battery, a plurality of periods and a threshold value corresponding to this are set, and the charging/discharging currents of the battery are restricted such that the total sum of currents during the periods or the total sum of the square of currents is set to the corresponding threshold or less. <P>COPYRIGHT: (C)2011,JPO&INPIT |
