“…A report by Grand View Research [2] estimated the REEVs would have a market growth of 100% in 2026 compared to 2018. REEVs use an electric motor (EM) for the sole propulsion of the vehicle, and range-extenders (REx), such as an internal combustion (IC) engine or a microturbine generator to charge the battery energy storage (BES) or to provide the electrical energy to the EM through power electronics hardware [3].…”

Vehicle driveability is one of the important attributes in range-extender electric vehicles due to the electric motor torque characteristics at low-speed events. Physical vehicle prototypes are typically used to validate and rectify vehicle driveability attributes. However, this can be expensive and require several design iterations. In this paper, a model-based energy method to assess vehicle driveability is presented based on high-fidelity 49 degree-of-freedom powertrain and vehicle systems. Multibody dynamic components were built according to their true centre of gravity relative to the vehicle datum to provide an accurate system interaction. The work covered a frequency of less than 20 Hz. The results consist of the components’ frequency domination, which was structured and examined to identify the low-frequency resonances sensitivity based on different operating parameters such as road surface coefficients. An energy path method was also implemented on the dominant component by decoupling its compliances to study the effect on the vehicle driveability and low-frequency resonances. The outcomes of the research provided a good understanding of the interaction across the sub-systems levels. The powertrain rubber mounts were the dominant component that controlled the low-frequency resonances (<15.33 Hz) and can change the vehicle driveability quality.

“…Several works discuss the application of Capstone® MGTs in HEV, such as investigating emission and operation strategy optimization of a 30 kW MGT for the New York M60 bus route [10] or comparing the performance of HEVs with 30 kW or 65 kW MGTs to a conventionally driven vehicle in the NEDC [11,12]. Further works experimentally investigate the performance of a Capstone® C30 based MGT in automotive drive cycles, quantifying the effect of ambient conditions or air filtration requirements as well as investigating the impact of different operation strategies [13][14][15]. The common conclusion is that the micro gas turbine based HEV can hold emission and performance benefits compared to conventional vehicles.…”

“…For example, Zhou et al 30 has proposed Chaos-enhanced Accelerate Particle Swarm Optimization for sizing a series hybrid power train to achieve global optimum. Additionally, prior studies investigated the feasibility of using an MGT for range extension in a hybrid electric vehicle, 31,32 where reductions in NO X and CO emissions were reported when compared to a traditional diesel engine. These reported environmental benefits of an MGT-based hybrid system provide additional motivation for this current work.…”

Inherent fuel flexibility of micro gas turbine (MGT) makes the engine a promising energy solution to remote Canadian communities that are not connected to the North American electricity grid, where bio-oils derived from locally available bio-mass may be utilized to meet local power and heat demands to reduce fossil fuel consumption. The switch to bio-oils enabled by MGTs reduces not only carbon footprints but also operating expenses due to high transportation costs of fossil fuels. However, MGT efficiencies are greatly reduced at partial loads. This work investigates the feasibility of addressing MGT efficiency drops at partial loads by incorporating MGT with a Battery Energy Storage System (BESS) to form a hybrid system so that the MGT can be operated at near full power at all times for better efficiencies. In this study, a daily power demand profile of a typical Canadian household is adopted for optimizing battery size and MGT operating strategies. By optimizing MGT daily start time and the engine's threshold partial load factor, the specific fuel consumption and battery size can be minimized for a specific number of households on a micro-grid supported by the MGT-based hybrid power system.
