This paper studies the simulation of the macro power flow and consumption in a traditional vehicle with either a single or dual voltage electrical architecture. As such, this involves primarily the simulation of the propulsion and electrical systems of the vehicle. Even in a traditional vehicle, these two systems do have substantial influence on one another with the mechanical interaction of the internal combustion engine (ICE) and the generator. This interdependence has grown as the electrical power budget of vehicles has increased. Delphi Automotive Systems and the National Renewable Energy Laboratory (NREL) collaborated to develop a simulation code to simultaneously model the mechanical propulsion and electrical systems of a vehicle. The co-simulation for traditional vehicles with either a single or dual voltage electrical architecture was released for free download globally in mid 2002, making this code available to all engineers in the automotive industry. This particular code is a portion of the larger ADVISOR product created by NREL with diverse partnerships. With the advent of 42V systems, the power and energy level of the electrical system increase the importance of simultaneous simulation of the electrical system and the mechanical system within the vehicle. The mechanical portion of the vehicle system is simulated in the traditional ADVISOR setting in MATLAB/Simulink. The electrical portion of the vehicle is simulated in Saber. This paper provides a full technical exposition of the following topics: the custom Saber models of automotive components available for download from NREL for Saber simulation of electrical architectures, the co-simulation technique, which is transparent to the end user, and sample benchmark analyses with emphasis on simulation results and co-simulation system performance.
