Abstract: A ground contact unit for a vehicle battery charging system comprises a base body, at least one potential layer, a plurality of contact areas, a plurality of switching units and a plurality of switching lines by means of which the switching units can be actuated, wherein a plurality of switching units are provided on each of the switching lines. The switching lines are subdivided into at least two groups, and each of the switching units is provided on at least two switching lines from at least two different groups, so that the switching state of the switching unit depends on the signal state on its associated switching lines. Each switching unit is coupled to at least one contact area such that the switching unit can electrically connect and interrupt the corresponding at least one contact area to the at least one potential layer assigned to the contact area. A method of switching a contact area is also shown.

Abstract: An underfloor charging unit, in particular for an electric charging system for an electrically driven vehicle, includes a housing having an upper side and a contacting opening, a cover and a driving device for actuating the cover. The cover covers the contacting opening in a closed position and unblocks the contacting opening in an open position, the driving device being configured so as to move the cover in an automated manner from the closed position to the open position and from the open position to the closed position, the cover, in the closed position, being arranged closer to the upper side than in the open position. A vehicle having an underfloor charging unit is furthermore shown.
