Guest Editorial: Special issue on transportation electrification and vehicle systems

Electrified vehicles include more electric vehicles (MEVs), hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs), and electric vehicles (EVs). This Special Issue is focused on transportation electrification and its enabling technologies and related vehicle and grid systems, components, and controllers. It includes state-of-the-art research and development contributions in the following areas: vehicular power electronics and electric motor drives; electric and hybrid electric powertrains; powertrain components and control; propulsion systems; energy storage systems; battery electronics; on-board and off-board chargers, fast chargers, and opportunity chargers; vehicle-to-grid (V2G) interface and grid interface technologies; EVs, HEVs, and PHEVs; electrification of trains and rail vehicles; applications of fuel cells in transportation; and electrical systems and components for various vehicles. For this Special Issue, we received 113 paper submissions. We have conducted a rigorous review process and have accepted 48 high-quality papers published in this Special Issue.We hope that this Special Issue serves as a reference for initiating and continuing state-of-the-art research in the critical areas of transportation electrification and vehicle systems.
