Making the Case for Electrified Transportation

Abstract

In order to achieve lower fuel consumption and less greenhouse gas (GHG) emissions, we need higher efficiency vehicles with improved performance. Electrification is the most promising solution to enable a more sustainable and environmentally friendly transportation system. Electrified transportation vision includes utilizing more electrical energy to power traction and nontraction loads in the vehicle. In electrified powertrain applications, the efficiency of the electrical path, and the power and energy density of the components play important roles to improve the electric range of the vehicle to run the engine close to its peak efficiency point and to maintain lower energy consumption with less emissions. In general, the electrified powertrain architecture, design and control of the powertrain components, and software development are coupled to facilitate an efficient, high-performance, and reliable powertrain. In this paper, enabling technologies and solutions for the electrified transportation are discussed in terms of power electronics, electric machines, electrified powertrain architectures, energy storage systems (ESSs), and controls and software.

Real-Time Optimal Energy Management of Electrified Engines

“…A switched reluctance motor (SRM) is selected as the EM. It is an excellent option in extra-high speed applications thanks to its simple structure, see Bilgin et al (2015). The EM can work in both assisting (motoring) mode and harvesting (generating) mode.…”

“…Moreover, w ∊ R m1 is the vector of exogenous inputs, z ∊ R p1 is the vector of regulated outputs. In the proposed ETDE control, w and z are defined as (9) and (10) where ΔN and ΔT L denote the disturbances on N and T L ; Δp in , Δp exh , ΔW egr denote the variations on p in , p exh , and W egr introduced by w, respectively. The full-order controller blocks diagram and the control implementation structure on the ETDE are illustrated as Fig.…”
