Abstract
A charging apparatus and a quality judging apparatus for a packed battery should be configured to prevent reduction of charging/discharging performance at the time of charging the packed battery, to improve reliability of the packed battery, and to secure safety of the packed battery.A charging controller is provided with a maximum value specifying means specifying a maximum value vmaxon of a cell voltage value based on a dispersion degree σ of a secondary cell, a third judging means judging whether or not the maximum value vmaxon of the cell voltage value, which is specified by the maximum value specifying means, reaches a permissible cell voltage value vc or not, and a charging voltage value change means changing a charging voltage applied by a voltage supply means based on a voltage difference between the maximum value vmaxon of the cell voltage value and the permissible cell voltage value vc when the third judging means judges that the maximum value vmaxon of the cell voltage value is larger than the permissible cell voltage value vc.
