ABSTRACT:
A charging apparatus charges a secondary battery, while controlling an output voltage of the charging apparatus to maintain the effective charging voltage at a substantially constant predetermined value at which the secondary battery is actually charged. Such a method prevents the secondary battery from being overcharged with a overvoltage, and enables the charging time to be short.
