PROBLEM TO BE SOLVED: To provide a novel battery inspection method. SOLUTION: In the impedance measurement which passes an AC current through a battery while changing its frequency, so as to measure the impedance of the battery for each frequency, the battery inspection method presets standard impedance as a standard for the impedance of a battery to be obtained by the impedance measurement. On the basis of the impedance of the battery, obtained by the impedance measurement and the standard impedance, the battery is inspected. COPYRIGHT: (C)2010,JPO&INPIT |
