ABSTRACT:
A charging apparatus for charging a secondary battery arranged in such a manner that the interterminal voltage of the battery, which is being charged, is measured so that the charging status of the battery is detected in accordance with the measured interterminal voltage of the battery which is being charged and the charging/discharging characteristics with respect to the interterminal voltage of the battery. As a result, the charging status of the battery can accurately be detected.
