Abstract: The present invention relates to a method for operating a charging device for charging energy stores of vehicles, preferably electric vehicles or hybrid vehicles, wherein the charging device is connected to an Internet-enabled server. In a method step, at least one receiver vehicle with a flat or partially charged battery communicates its charging demand to the charging device. Furthermore, in a method step at least one donor vehicle with an at least partially charged battery communicates its readiness to charge to the charging device.

Abstract: The invention relates to the establishing of a communication connection between an electric or hybrid vehicle and a charging station. To this end, a transfer protocol, which enables communication between the electric or hybrid vehicle and the charging station, can be selected either in the electric or hybrid vehicle or alternatively in the charging station. Selection of a transfer protocol from a plurality of available transfer protocols enables a flexible coupling between the electric or hybrid vehicle and the charging station to be achieved.
