Abstract: A method is provided for determining a property of a charging station, wherein the charging station is designed to provide electrical energy for charging a vehicle. The method determines vehicle data, wherein the vehicle data were created by a first vehicle with respect to a charging operation of the first vehicle at the charging station. In addition, the method determines a property of the charging station on the basis of the vehicle data. Furthermore, the method provides data that indicate the determined property of the charging station.

Abstract: A system for charging an electrical energy store of a vehicle includes a vehicle and a charging apparatus coupled to a power supply system. The vehicle comprises a plug with a first group of first contacts and a second group of second contacts, wherein, in order to form a first current path, the first contacts of the first group are coupled to the electrical energy store of the vehicle by a first voltage converter which is controllable by a first charge control unit. Moreover, in order to form a second current path, the second contacts of the second group is coupled to the electrical energy store of the vehicle by a first switching device, wherein the switching states of said first switching device are controllable by the first charge control unit.
