Abstract: A method is provided for dynamically providing up-to-date information about charging stations for electric vehicles. Charging station information including at least one charging station identification assigned to a respective charging station and location information assigned to the respective charging station is stored for multiple charging stations. A charge request containing identification of the mobile station and geographical information for the mobile station is received from a mobile station. A tuple of charging station information from the plurality of items of stored charging station information dependent on at least the received charge request is selected such that the received geographical information is compared with the respective location information of the charging stations and when the result of a comparison is positive the corresponding charging station information is added to the tuple and the tuple is sent to the mobile station using the identification of the mobile station.

Abstract: Method for operating a charging station for electric vehicles in which a charging power is negotiated between a charge control device of the electric vehicle and the charging station, the charge control device controls a charging current which is transmitted from the charging station to the electric vehicle in accordance with the charging power negotiated, wherein a continuous power rating and a maximum power of the charging station which is greater than the continuous power rating are determined. In order to optimise the charging power and to accelerate a charging operation, it is proposed that a charging power which is above the continuous power rating and which at most corresponds to the maximum power is first negotiated, that the temperature in the charging station be monitored, and that, when a limit temperature is exceeded, a new charging power which at most corresponds to the continuous power be negotiated.
