Abstract
In a secondary battery charging system and charging apparatus, when using either a step-down method or a constant-current/constant-voltage method of charging a secondary battery, a switching regulator is used to vary the charging current supplied to a secondary battery in accordance with the duty cycle of one pulse, so that a voltage that exceeds a pre-established voltage value is not applied to the secondary battery.
