Abstract
Abstract This paper investigates a 10-kW micro gas turbine (MGT) as range extender (RE) for Range-Extended Electric Vehicles (REEVs). The MGT structure is designed and the simulation model of the MGT with a speed control system is built in MATLAB/Simulink. A novel configuration of the REEV equipped with MGT is presented. Then, a performance simulation model of the REEV is adopted to analyze the technology economic performance of the MGT range extender and the gasoline ICE range extender comparatively. The simulation results show that with a RE of 10 kW, the REEV could have 600 km driving range. In addition, the REEV equipped with the MGT can operate with lower energy consumption and the concentration of NOx, CO emissions are 24% and 9% of the ICE REEV, respectively. Finally, the battery pack energy is optimized to study its impact on fuel economy, which indicates that when the battery pack energy is 20 kW·h, the REEV performs optimal energy consumption and emissions in the example.
