Abstract
This paper deals with the design and implementation of an energetically optimized power system for premium class vehicles. In order to use future fuel saving technologies such as start-stop and recuperation of braking energy a hybrid power system with 168 V - 12 V voltage levels has been introduced in an overall vehicle simulation using Dymola/Modelica. For control and coordination of electrical consumers, the generator, the buffer storage device and the DC-DC-converters an energy management system has been developed, which distributes resources (power) based on the principles of an open energy market. Design and functionality of the energy management system are described in detail and simulation results are being presented.
