Abstract
A charging system supplies a charging current of a constant value (Icc) to a secondary battery, performs a constant-current charging using the charging current until the CCV of the secondary battery reaches a predetermined threshold voltage (Vcc), and repeats a predetermined number of times (N times): —reducing the charging current currently being supplied by a predetermined current reduction amount (ΔIc), —setting the reduced charging current as a new charging current, and —performing the constant-current charging using the new charging current until the CCV of the secondary battery increases by a predetermined voltage increase amount (ΔVx), and then stops the supply of the charging current. The current reduction amount (ΔIc) is set so that the CCV of the secondary battery is larger than the fully-charged voltage (Vfull) of the secondary battery when the charging current currently being supplied is reduced by (ΔIc).
