Abstract: A device for providing charging information for a charging process is configured to determine a total set of N data tuples for N different times of a charging time period for the charging process. A data tuple includes values of one or more characteristic variables relating to electrical energy that can be provided in the charging process. Furthermore, the device is configured to reduce the total set of N data tuples to a reduced set of M data tuples, with M<N, and to provide the reduced set of M data tuples for the determination of a charging plan for the charging process.

Abstract: A method for determining a charge plan for an electrical energy store of a vehicle includes subdividing a charging time interval, which is available for charging the energy store, into a sequence of time segments, such that constant charging power conditions are respectively present in the time segments in the sequence of time segments. For each time segment in the sequence of time segments, a limited number of possible charging powers with which the energy store can be charged and/or discharged in the respective time segment are determined. A plurality of sequences of charging points are determined, where each of the charging points indicates a charging power from the limited number of possible charging powers for a given time segment from the sequence of time segments, and where each sequence of charging points from the plurality of sequences of charging points indicates a sequence of charging powers for the sequence of time segments.

Abstract: A method for determining an operating strategy for an electrical energy store includes subdividing an operating time interval, for which the operating strategy of the energy store is intended to be determined, into a sequence of time segments such that constant power conditions are respectively present in the time segments in the sequence of time segments. For each time segment in the sequence of time segments, a limited number of possible operating powers with which the energy store can be charged and/or discharged in the respective time segment are determined. A plurality of sequences of operating points are determined, where each of the operating points indicates an operating power from the limited number of possible operating powers for a given time segment from the sequence of time segments, and where each sequence of operating points from the plurality of sequences of operating points indicates a sequence of operating powers for the sequence of time segments.

Abstract: Predetermined macrosegments of the fundamental frequency are determined by a neural network, and these predefined macrosegments are reproduced by fundamental-frequency sequences stored in a database. The fundamental frequency is generated on the basis of a relatively large text section which is analyzed by the neural network. Microstructures from the database are received in the fundamental frequency. The fundamental frequency thus formed is thus optimized both with regard to its macrostructure and to its microstructure. As a result, an extremely natural sound is achieved.

Abstract: A current first state, of a first temporal sequence of respective first states of a dynamically modifiable system, is determined. The first current state of the system is determined by combining a first system-inherent information flow comprising past system information of the system with a second system-inherent information flow comprising future system information in the first current state. The first current state is then determined from the combination.

Abstract: The invention relates to the computer-assisted mapping of a plurality of temporarily variable status conditions. According to the invention, a first status description in a first state space is mapped onto a second status description in the second state space by mapping, and the second status description of a temporarily later state is taken into consideration during mapping. By carrying out a further mapping, the second state description is mapped back onto a third state description in the first state space.
