Abstract
A charging apparatus comprises a charge control unit. The charge control unit charges a secondary battery at a first current value until the voltage of the secondary battery reaches a predetermined first voltage value. The charge control unit, on detecting that the voltage has reached the first voltage value, performs control to charge the secondary battery at a second current value that is lower than the first current value, until a predetermined second voltage value is reached.
