This invention provides a rotating charging device for use in automated parking garages. The charging device includes a charging unit, a swing arm unit, a rotation drive unit, a position detection unit, and a control unit. The charging unit is connected to one end of the swing arm unit, and the rotation drive unit is connected to the other end of the swing arm unit.
