Hybrid and electric vehicles are complex and there is no master rule to find the best design. Here numerical simulation can help for the early decisions at the power train configuration. Within this context the system level modeling of vehicle power train is the object of study and in this work is shown how design evaluations can be easily simulated. The numerical models are implemented based on the open source and verified FAT-AK30 library using IEEE standard language, VHDL-AMS. The know-how added is at the interpretation of the library and application into the ANSYS-Simplorer environment oriented to a parallel hybrid electric vehicle demonstration case.

In the recent years there has been observed an increasing concern about global warming and greenhouse gas emissions. In addition to the environmental issues the predicted scarcity of oil supplies and the dramatic increase in oil price puts new demands on vehicle design. As a result energy efficiency and reduced emission have become one of main selling point for automobiles. Hybrid electric vehicles (HEV) have therefore become an interesting technology for the automotive industries. HEV are more complicated compared to conventional vehicles due to the fact that these vehicles contain more electrical components such as electric machines, power electronics, electronic continuously variable transmissions (CVT), and embedded powertrain controllers. Advanced energy storage devices and energy converters, such as Li-ion batteries and fuel cells are also considered.
