The continuing electrification of powertrains is driving automotive architectures toward electrical power distribution grids, specifically modern nanogrids. This transformation is being driven in part by traction motors capable of regenerative braking and partly by the inclusion of the large storage battery into the powertrain domain. The power grid model consists of generation, transmission, and distribution components, as well as grid-scale storage, and all have automotive analogs and hold the potential of more broadly shared technologies and components. This paper will examine some pitfalls that have become apparent with the emergence of modern hybrid and plug-in vehicles (including PHEV and EV), and some potential lessons from 100 years of utility power production. It will also examine some extrapolations and potential benefits from the looming synergistic unification of these previously unrelated power technologies.

Abstract This paper discusses the torque-fill capability of a novel hybrid electric drivetrain for a high-performance passenger car, originally equipped with a dual-clutch transmission system, driven by an internal combustion engine. The paper presents the simulation models of the two drivetrains, including examples of experimental validation during upshifts. An important functionality of the electric motor drive within the novel drivetrain is to provide torque-fill during gearshifts when the vehicle is engine-driven. A gearshift performance indicator is introduced in the paper, and the two drivetrain layouts are assessed in terms of gearshift quality performance for a range of maneuvers.
