Abstract
This work is devoted to the efficient simulation of large multi-physicalnetworks stemming from automated modeling processes in system simulation soft-ware. The simulation of hybrid, battery and fuel cell electric vehicle applications re-quires the coupling of electric, mechanic, fluid and thermal networks. Each networkis established by combining the connection structure of a graph with physical equa-tions of elementary components and resulting in a differential algebraic equation(DAE). In order to speed up the simulation a non-iterative multirate time integrationco-simulation method for the system of coupled DAEs is established. The power ofthe multirate method is shown via two representative examples of a battery poweredelectric vehicle with a cooling system for the battery pack and a three phase inverterwith a cooling system.
