Abstract: A method for operating an electric vehicle having a fuel cell system and a traction battery involves specifying a target state of charge of the traction battery using the topography in the surroundings of the vehicle, for which the position of the vehicle is determined and elevations in a specified perimeter around the vehicle are determined from a digital map, from which a conclusion is drawn about the probable occurrence of uphill and/or downhill sections, whereupon the target state of charge is specified depending on the probability of uphill and/or downhill sections.

Abstract: The invention describes a broadband matching network for coupling to an output of an amplifying device for amplifiers with a nominal operating frequency between 1 MHz and 100 MHz. The broadband matching network comprises a planar transformer with a primary winding arranged on a primary side of the broadband matching network and a secondary winding arranged on a secondary side of the broadband matching network. The primary winding is arranged to be electrically connected to the output of the amplifying device. The broadband matching network is characterized by a center frequency and a bandwidth with a frequency range of at least +/?3%. A first parallel resonance frequency and a second parallel resonance frequency of the broadband matching circuit are arranged around the series resonance frequency such that a frequency dependence of a load impedance provided by the broadband matching network for the amplifying device is reduced.

Abstract: A method for controlling at least one component of a motor vehicle, involves determining a current driving profile of the motor vehicle using at least one sensor present in the motor vehicle and comparing the current driving profile to a stored reference driving profile. At least two different components are simultaneously controlled depending on a result of this comparison.
