Significant global efficiency improvements can be achieved once is identified the system energy breakdown, individuating the losses connected to each powertrain component; it is then possible to carry out the most appropriate interventions. This paper presents a simulation ...

The design of a full electric vehicle (or battery electric vehicle (BEV)) requires the development and optimization of a complete electric powertrain, including battery, power electronics, electric machine, sensors and control system. When designing an electrical platform, from the very beginning of the V-cycle, it is mandatory to rely on modelling and simulation tools in order to drive the mai...

In this study, an integrated energy management strategy(IEMS) was proposed for a PHEV(Plug-in hybrid electric vehicle). The IEMS controls the engine on-off considering not only powertrain system(battery SOC, vehicle speed, accelerator pedal, brake pedal) but also thermal system condition such as cabin temperature. Analysis of the integrated powertrain and thermal system was conducted to enhance...
