Method for loading power supply unit of hybrid electrical motor car, involves releasing charging cable from electric motor vehicle after receiving universal release lock signal when charging process is completed at that time

The method involves locking a charging cable (2) before start of a charging process on an electric motor vehicle (1). The charging cable is released from the electric motor vehicle after receiving a universal release lock signal when the charging process is completed at that time. A receiving unit (8) is provided for wireless reception of the universal release signal. A locking system is actuated by a control device for selectively locking or unlocking a vehicle door of the electric motor vehicle. Independent claims are also included for the following: (1) an electrical motor car (2) a vehicle arrangement. Die Erfindung betrifft ein Verfahren zum Aufladen einer Energieversorgungseinheit (6) eines Elektrokraftfahrzeugs (1) mit elektrischer Energie von einer ein Ladekabel (2) aufweisenden elektrischen Ladestation (3), - gemäß welchem das Ladekabel (2) vor Beginn eines Ladevorgangs am Elektrokraftfahrzeug (1) verriegelt wird, - gemäß welchem vom Elektrokraftfahrzeug (1) nach Empfang eines universellen Freigabesignals die Verriegelung des Ladekabels (2) freigegeben wird, wenn der Ladevorgang zu diesem Zeitpunkt abgeschlossen ist.
