Multi-Physic Modeling and Simulation of a Hybrid Vehicle with Range Extender.

As the global economy begins to strain under the pressure of raising petroleum prices and environmental concerns, automobile manufacturers constantly strive to produce more fuel efficient and environmentally friendly vehicles. That’s why mechatronic sophistication in automotive vehicles is increasing. Given the current resources and technologies, the most feasible solution is hybrid electric vehicles (HEV). HEVs can be organized into three classes: parallel, series and power-split hybrids. In an electric car with a Range Extender, only the electric motor drives the wheels. It is powered by a battery for a few tens of kilometers. Then when the battery reaches a level load of about 30%, a thermal engine optimized, which drives a current generator, starts producing electricity for the onward journey. In this paper, we focused on the series hybrid architecture. We analyzed different architectures and more precisely the hybrid solar vehicle with Range Extender. We developed a dynamic model of this multidisciplinary system and its control unites using software of multi-physics modeling. The simulation results were used for an operating cycle NEDC (New European Driving Cycle) to optimize fuel consumption.
