[Problem to be Solved] To provide a regulator capable of more appropriately preventing the voltage of a battery from increasing beyond a full-charge voltage during a battery chattering. [Solution] A regulatorincludes a rectifying circuit, a first battery detecting circuit, a first full-charge detecting circuit, a first differentiating circuithaving a fifth resistor rconnected between a first terminal Tand one end of a first capacitor Cand a second capacitor connected in series with the fifth resistor rbetween the first terminal Tand one end of the first capacitor C, and a first driving circuit DR that controls the rectifying circuitto rectify an alternating current according to output of an alternating-current generator ACG and controls the rectifying circuitto operate or stop according to signal at one end of a first battery connecting switch element SW

Regulator, battery charging apparatus and battery charging method to prevent voltage of a battery from increasing beyond a full-charge voltage during chattering
