AbstractElectric and hybrid vehicles are going to become the most reliable source of transport for future years. The CO2 and NOx targets in Euro 6 normative puts the producers of vehicles in a dilemma, whether to adapt the internal combustion engines further, or to develop hybrid or electric power trains that are going to reach the pollution limit of the future norms or to go below that. Before acting a well-developed strategy in determining the optimum power flow has to be developed by producers; CRUISE software is a tool with the unique and special characteristics to determine the optimum in this highly important area.Whether electric vehicle, electric vehicle with range extender or a hybrid with CVT or planetary gearbox, the complexity of the mathematical modules remains the same, giving the developer the possibility to create complex functions and distinctive characteristics for each component of the vehicle.With such a powerful tool it becomes extremely easy to evaluate the energy flow in all directions, from electric machine to the battery, from electric machine to the power generator, and from the electric machine to the internal combustion engine. Applying to the (Electric Vehicle, Electric Vehicle with Range Extender, Hybrid vehicle with CVT, Hybrid vehicle with planetary gear set) the ECE-15 in a virtual environment (urban driving cycle) the simulation results show a different usage, rate of storage and efficiency concerning the energy, this being dependent of the power train configuration in most part.

Abstract The free piston linear generator is a new range extender concept for the application in a full electric vehicle. The free piston engine driven linear generators can achieve high efficiency at part and full load which is suitable for the range extender application. This paper presents requirements for designing a linear generator deduced from a basic analysis of a free piston linear generator.

A range extender is an auxiliary power unit, usually consisting of an internal combustion engine and an electric generator, which is used to charge a battery of an electric vehicle in order to increase its range. This paper considers a range extender supplied with liquefied petroleum gas (LPG). The aim is to provide detailed data on thermal efficiency, brake specific fuel consumption (BSFC), and unit emission of carbon dioxide (CO2) in a broad spectrum of range extender operating conditions defined by rotational speed and torque. The experimental investigation has been conducted using a laboratory test stand equipped with an energy dissipation system of adjustable resistance. Measurement results, including fuel flow rate, were processed using custom algorithm for generating maps, i.e., two-dimensional dependencies of the considered parameters on the rotational speed and torque. The maps obtained for LPG supply were compared with those for gasoline supply. The results demonstrated feasibility of LPG-supplied range extender. Its BSFC and thermal efficiency were at a comparable level to those obtained for gasoline supply, but with less CO2 emission. The empirical data collected has been adopted in the simulation of extended-range electric vehicle in a driving cycle, showing the potential of utilizing the results of this study.

Electric vehicles are recognized as an effective way to alleviate the energy crisis and environmental degradation, and extended range electric vehicles which have both the technical advantages of hybrid electric vehicles and pure electric vehicles, have gradually become a research hotspot in the automotive industry. In this paper, the system structure design of the extended range electric vehicle is carried out. On the basis of the pure electric vehicle, the engine and generator set are added. The control strategy model is established and the simulation research is carried out. The results show that the proposed control strategy model optimizes the working range of the range extender, takes into account the performance of the battery and the drive motor, and shows good tracking characteristics.
