<P>PROBLEM TO BE SOLVED: To provide a method for generating remaining capacity data of a secondary battery that prevents discontinuous change of remaining capacity data to be output and a battery pack that outputs remaining capacity data generated by the method for generating remaining capacity data. <P>SOLUTION: If a minimum cell voltage detected at a 250-ms cycle in a time-series manner decreases to a predetermined low voltage (3.3 V or 3.6 V) or lower and a remaining capacity integrated so far is greater than the modified 4% or 8% capacity set in advance for the predetermined low voltage, the battery pack outputs data on a corrected capacity using the capacity obtained by reducing the remaining capacity in increments of 1% every 8 seconds as the corrected capacity. The battery pack begins the integration of a second remaining capacity where the modified capacity is used as a reference capacity after it has started outputting the data on the corrected capacity, and starts outputting the data on the second remaining capacity once the corrected capacity being output matches the second remaining capacity. <P>COPYRIGHT: (C)2012,JPO&INPIT |
