Abstract
A battery charging apparatus that controls charging of a battery by an alternating-current generator, the battery charging apparatus has a first switch element connected to a first battery terminal to which a positive electrode side of the battery is connected in a normal connection of the battery at a first end thereof and to a first generator terminal to which a first output of the alternating-current generator is connected at a second end thereof, and a second switch element connected to the first battery terminal at a first end thereof and to a second generator terminal to which a second output of the alternating-current generator is connected at a second end thereof. In a case when a controlling circuit stops controlling the first switch element and the second switch element, and the first switch element and the second switch element are turned off, a detecting circuit, which detects a reverse connection condition of the battery, forcedly turns on at least one of the first switch element and the second switch element when the detecting circuit detects the reverse connection condition of the battery.
