Start&Stop Energy Management Strategy for a Plug-In HEV: Numerical Analysis and Experimental Test

The big effort spent by researchers towards green vehicles, capable to reduce pollutant emissions and fuel consumption, is directed to the analysis of hybrid electrical vehicles. The design of hybrid vehicles drive train requires a complete system analysis including the control of the energy given from the on board source, the optimization of the electric and electronic devices installed on the vehicle and the design of all the mechanical connections between the different power sources to reach required performances. The aim of this paper is to point out some results obtained from the energetic model and from the experimental tests performed on the plug-in hybrid electrical vehicle (PHEV), realized, in prototypal version, at the Dipartimento di Meccanica of the Politecnico di Milano [1]. In particular the paper focuses the attentions on the benefits achieved with a Start&Stop energy management strategy.
