“…Micro gas turbines (MGTs) are small and high-speed gas combustion turbines that have a power output ranging from 30 kW to over 200 kW [56]. MGTs can operate as range extenders in EVs because they act as generators that can charge the depleted Li-ion battery [57]. They appeared in the automotive market in the 195 and were designed to be used in aircraft, commercial buses, and missile launching stations [58].…”

Emissions from the transportation sector are significant contributors to climate change and health problems because of the common use of gasoline vehicles. Countries in the world are attempting to transition away from gasoline vehicles and to electric vehicles (EVs), in order to reduce emissions. However, there are several practical limitations with EVs, one of which is the “range anxiety” issue, due to the lack of charging infrastructure, the high cost of long-ranged EVs, and the limited range of affordable EVs. One potential solution to the range anxiety problem is the use of range extenders, to extend the driving range of EVs while optimizing the costs and performance of the vehicles. This paper provides a comprehensive review of different types of EV range extending technologies, including internal combustion engines, free-piston linear generators, fuel cells, micro gas turbines, and zinc-air batteries, outlining their definitions, working mechanisms, and some recent developments of each range extending technology. A comparison between the different technologies, highlighting the advantages and disadvantages of each, is also presented to help address future research needs. Since EVs will be a significant part of the automotive industry future, range extenders will be an important concept to be explored to provide a cost-effective, reliable, efficient, and dynamic solution to combat the range anxiety issue that consumers currently have.

“…In reference [16], related gain coefficients among rotate speed, fuel, and EGT are used to model the two-spool turboshaft engine based on the experimental data, and the selections of gain coefficients in simulation rely on the rotate speed. In references [14,17], the dynamics model of one-spool turboshaft engine is built for the startup process, but the dynamics characteristics in loading process at rated rotate speed are not discussed. In fact, the turboshaft engine with one-spool in HPU is used as the main energy source to output power, and the dynamics characteristics of the engine can have an impact on the performance of HPU.…”

In recent years, the green aviation technology draws more attention, and more hybrid power units have been applied to the aerial vehicles. To achieve the high performance and long lifetime of components during varied working conditions, the effective regulation of the energy management is necessary for the vehicles with hybrid power unit (HPU). In this paper, power prediction-based model predictive control (P2MPC) for energy management strategy (EMS) is proposed for the vehicle equipped with HPU based on turboshaft engine in order to maintain proper battery’s state of charge (SOC) and decrease turboshaft engine’s exhaust gas temperature (EGT). First, a modeling approach based on data-driven method is adopted to obtain the mathematical model of turboshaft engine considering time delay and inertial of states. An integrated power predictor consisting of the classification of input status and the subpredictors are developed based on the deep learning method to improve the accuracy of the prediction model of the model predictive control (MPC). Subsequently, an EMS based on MPC using the proposed power predictor is introduced to regulate the SOC of battery and the EGT of turboshaft engine. The comparison with experimental results shows the high accuracy of mathematical model of turboshaft engine. The simulation results show the effectiveness of the proposed EMS for the vehicle, and the effects of different weight coefficients of objective function on the proposed EMS are discussed.

The combination of two drive sources: the internal combustion engine and the electric motor in the hybrid drive system requires an appropriate control system to manage their operation. It relies on many variables, and the greater the degree of drive hybridization the greater is the degree of interdependence of the parameters involved. The article presents solutions of electric drive control algorithms with an additional power source in the form of an internal combustion engine (Range Extender). The results of simulation analyzes in the AVL Cruise program are presented, taking into account three control algorithms and two driving cycles. The obtained results indicate the necessity to take various input quantities into account in order to optimize the use of the combustion engine
