Abstract (en)
[origin: WO2022233881A1] The invention relates to a ground contact unit (10) for a vehicle battery charging system for automatic, conductive connection to a vehicle contact unit. The ground contact unit (10) has a plate-like main body (12), at least one potential level (18) and a plurality of contact regions (16) which are arranged on an exposed charging area (14) of the main body (12) with which the vehicle contact unit can come into contact and are associated with the at least one potential level (18). At least one protective assembly is associated with the contact regions (16) of the at least one potential level (18). The at least one protective assembly has a current measuring unit, which is provided in the current path, for measuring current and a switch, which is arranged in the current path and is controlled, amongst other things, depending on the result of the current measuring unit.
