Abstract: A method for determining an intelligent preselection of suitable charging stations for involves providing an indication to perform a charging stop at a suitable charging station depending on a recorded variable in the form of at least one vehicle requirement, user requirement and/or environmental factor. A value of at least one vehicle requirement, user requirement, environmental factor, and/or a journey-specific factor deviating from the recorded variable is estimated by evaluating the recorded variable and at least one suitable charging station for carrying out the charging stop is suggested depending on the recorded variable and the estimated value by a comparison of the requirements and/or factors with at least one charging station-specific attribute.

Abstract: A toll system implements a payment process for traveling on a chargeable route segment with a vehicle. A mobile unit is assigned to the vehicle and a stationary unit is assigned to an operator of the chargeable route segment. A rate of a toll depends on at least two cost parameters. The mobile unit determines the at least two cost parameters and directly or indirectly communicates with the stationary unit in order to implement the payment process. The mobile unit also performs an optimization step in order to find an optimal, cost-effective parameter configuration.

Abstract: A method for providing context-dependent information about and/or paying for road sections subject to a toll on a route that is used by a vehicle. Information relating to the use of at least one road section subject to a toll is transmitted to a billing service provider authorized to bill for the payment. A current vehicle position and a current direction of travel of the vehicle are compared with a digital road map in order to detect when the vehicle approaches a road section subject to a toll, and, by manual call-up or when it is detected that the vehicle is approaching the road section subject to a toll, information characterizing the road section is displayed on a display in the vehicle, and/or an authorization to use the road section subject to a toll is obtained from the billing service provider.

Abstract: A method for filling an energy storage device of a motor vehicle by a charging device involves the motor vehicle being closer to the charging device than a predetermined threshold distance. A billing account associated with the motor vehicle is provided with a clearly identifiable, wirelessly transmitted identifier for the charging device by an electronic computing device of the motor vehicle. The energy storage device is filled by the charging device, and in accordance with the filling and the billing account is automatically debited.
