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.

AS4283C
This SAE Aerospace Standard (AS) covers handles and attachments for use with sockets and crowfoot wrenches in aerospace applications involving high torque, limited clearances, and generally clean conditions. This document provides additional requirements beyond ANSI B107.10M appropriate for aerospace use. The use of adapters, either enlarging or reducing, for turning high-strength fasteners is an unsafe practice. Adapters are not included in this document. Inclusion of dimensional data in this document is not intended to imply all of the products described therein are stock production sizes. Consumers are requested to consult with manufacturers concerning lists of stock production sizes.

AS4167C
This SAE Aerospace Standard (AS) covers 12 point flare nut crowfoot, flare nut wrenches, double end flare nut wrenches, combination box and flare nut wrenches, and ratcheting flare nut wrenches that are designed with the following requirements: a. Non-distorting usage b. Possessing the strength, clearances, and internal wrenching design to be used on hydraulic tube fittings that conform to the requirements of SAE J514. c. Transmitting torque to tube fittings without bearing on the apex of fitting wrenching points. Inclusion of dimensional data in this document is not intended to imply that all of the products described herein are stock production sizes. Consumers are requested to consult with manufacturers concerning lists of stock production sizes.

AS954H
This SAE Aerospace Standard (AS) covers high strength thin wall (commercial) sockets, universal sockets, box wrenches and torque adaptors which possess the strength, clearances, and internal wrenching design so configured that, when mated with 12-point fasteners conforming to the requirement of AS870, they shall transmit torque to the fastener without bearing on the outer 5% of the fastener's wrenching points. Inclusion of dimensional data in this document is not intended to imply that all of the products described herein are stock production sizes. Consumers are requested to consult with manufacturers concerning lists of stock production sizes. The dimensional limits of box and combination wrench lengths have been established to provide configuration control for tool storage applications.

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.
