Full energetic model of a plug-in hybrid electrical vehicle

Nowadays the greatest part of the efforts to meet fuel economy and to reduce pollutant emissions are directed toward the hybridisation of automotive drive trains. In particular the design of hybrid vehicles requires a complete system analysis including the control of the energy given from the on board source, the optimisation of the electric and electronic devices installed on the vehicle and the design of all the mechanical connection between the different power sources to reach required performances. The aim of this paper is to develop an energetic model for analysis, design and control of a plug-in hybrid electrical vehicle (PHEV) with particular attention paid to energy and power flux between the different devices. The model described in the following paragraphs has been experimentally validated on a Plug-in HEV, realized, in prototypal version, at the Mechanical Department of the Politecnico di Milano.
