<p><P>PROBLEM TO BE SOLVED: To facilitate detecting characteristics of a secondary battery, especially a full charge capacity and an internal resistance of the secondary battery with high accuracy. <P>SOLUTION: When a terminal voltage of the secondary battery reaches a voltage determined beforehand during charge, charge is stopped, and after an open terminal voltage of the secondary battery is detected, charge is restarted and continued up to full charge, and the full charge capacity of the secondary battery is calculated based on a charge capacity in a recharge period and an open terminal voltage detected at the charge stopping time and an open terminal voltage detected after full charge. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
