The increasing electrification of the drive train in the automotive environment leads to higher requirements for automotive systems and their design. Therefore, a computer based methodology to support the engineer in the design phase of car concepts, components and control algorithms is desirable. All relevant sections of a vehicle development process, e.g. longitudinal and lateral dynamics, thermal management or the power supply should be considered. Due to this necessity a new holistic vehicle library is developed at the Forschungsgesellschaft Kraftfahrwesen mbH Aachen (fka) and Institute of Automotive Engineering (ika) of RWTH Aachen University. The introduced holistic method is applied exemplarily on architecture with the traction battery as thermal storage to determine the potential of such a design on the overall efficiency and to analyse different operational strategies.
