Abstract: A charging device and method for electrically charging an electric vehicle includes a first coupling element connectable to a second coupling element arranged on the electric vehicle to produce an electrical connection. The the charging device includes a base, which can be at least partially sunk into the ground, and a movement apparatus, which connects the first coupling element to the base to be controllably moved relative to the base. The base includes a through-opening and a cover that closes the through-opening, so that, in a usage state, the first coupling element, with the cover open, is movable through the through-opening from a non-charging position sunk into the ground using the movement apparatus, to guide the first coupling element to the second coupling element to a charging position.

Abstract: A first component of a charging device for the electrical energy exchange of an object with a storage battery, in particular for charging a storage battery, for example a storage battery of an electric vehicle, which first component comprises a contacting element. The contacting element can be connected to a coupling element of a second component to produce an electrical connection. A base and an arm arranged thereon are provided, wherein the arm is mounted on the base such that it can move about and/or along multiple axes in order to guide the contacting element to the coupling element. A charging device having has a component of this type as well as a second component with an engaging element, wherein one of the components is fixed in a stationary manner. Further, a use of a first component and to a method for electrically charging a device is disclosed.
