<P>PROBLEM TO BE SOLVED: To provide an overcharge detection method capable of highly accurately detecting an overcharged state. <P>SOLUTION: A concentration of oxygen in an electrolyte 7, which is generated from a cathode 2 by overcharge, can be measured by measuring a voltage between a sensing electrode 21 and an anode terminal 11 of a nickel-hydrogen storage battery 1, with a voltmeter 22. Therefore, it is possible to highly accurately detect that the nickel-hydrogen storage battery 1 during charging has reached an overcharged state. <P>COPYRIGHT: (C)2012,JPO&INPIT |
