Abstract
A battery charging apparatus comprising a controller to control on-off controllable switch elements of an AC power source output short circuit and including a first control section to control the on-off controllable switch elements so that they are at an on-state when an instantaneous terminal voltage of a battery exceeds a first set value and a second control section to control the on-off switch elements so that they are at an on-state when an average voltage of the battery exceeds a second set value and serving to control them when a power source switch is closed.
