Method and system for dynamically providing information about charging stations
First Claim
1. A method for providing information about charging stations for electric vehicles, comprising the steps of:
- storing, for a plurality of charging stations, charging station information comprising at least one charging station identification assigned to a respective charging station and at least one item of location information assigned to the respective charging station;
receiving from a mobile station a charge request containing at least one identification of the mobile station and one item of geographical information for the mobile station, wherein the charge request in addition contains information whether the electric vehicle is charged with direct current or alternating current;
selecting a tuple of charging station information from the plurality of items of stored charging station information dependent on at least the received charge request such that the received geographical information is compared with the respective location information of the charging stations and when the comparison results that a defined distance value between charging station and mobile station is not exceeded, the corresponding charging station information is at least in part added to the tuple; and
sending the tuple, at least in part, to the mobile station using the identification of the mobile station.

Abstract
The invention relates to a method 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 a plurality of 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.
