10 Oct 2008TL;DR: In this paper, a method for controlling a powertrain system includes monitoring a state-of-charge of the energy storage device and determining a first set of electric power limits and a second set of electrical power limits based on the state of charge of the device.
Abstract: A method for controlling a powertrain system includes monitoring a state-of-charge of the energy storage device and determining a first set of electric power limits and a second set of electric power limits based on the state-of-charge of the energy storage device. The method further includes providing a power range for opportunity charging and discharging of the energy storage device based on the first set of electric power limits. The method further includes providing a power range for controlling output power of the energy storage device based on the second set of electric power limits.

TL;DR: In this article, the authors present a methodology for determining whether an energy storage unit (ESU) should consist of only batteries, only ultracapacitors or a combination of both.
Abstract: Hybrid and electric vehicles (HEV, EV) require some form of energy storage in order to achieve load leveling or efficiently manage power flows, mainly when accelerating or decelerating. Traditionally, batteries have been used but recently ultracapacitors have become potential candidates for energy storage in HEV/EV applications. To this end, this paper first presents a methodology for determining whether an energy storage unit (ESU) should consist of only batteries, only ultracapacitors or a combination of both. An example illustrates the feasibility of the proposed ideas. Finally, the paper concludes with a cost analysis of the different ESU alternatives.

TL;DR: In this paper, a power/data tap for delivering both electrical power and data service line to a work surface from a distant standard wall or floor mounted electrical receptacle and data port is presented.
Abstract: A temporary power/data tap for delivering both electrical power and data service line to a work surface from a distant standard wall or floor mounted electrical receptacle and data port. The power/data tap is designed to be selectively moved between retract and extended positions to provide electrical power and data service line to the work surface. The power/data tap is a self-contained unit designed for easy installation on the work surface which meets or exceeds United Laboratory standards. At least one electrical receptacle and one data port is mounted on a pivoting outlet enclosure housed inside an enclosure assembly. The electrical receptacle and data port are disposed in two separate compartments formed in the outlet enclosure. A power cord capable of being plugged into a standard wall or floor receptacle delivers electrical power to one side of the enclosure assembly. A power distribution assembly located inside the enclosure assembly then safely distributors the electrical power inside the enclosure assembly. Optional electrical connectors and interconnecting cable is provided for electrical power from one power/data tap to another.
