Battery operated electric vehicles (BEVs) offer the opportunity of running a zero-emission car fleet. However, due to their current range constraints, electric vehicle operations are mainly attractive for inner-city transport, such as the taxi business. This paper is bringing together facts and assumptions about Berlin’s taxi transport and the current conditions of BEVs in Germany to provide th...

Based on the structural features of electric vehicle (EV) driven by in-wheel motors and the characteristics of low speed as well as high torque for in-wheel motors, regenerative braking method for in-wheel motors has been presented. All braking torque for vehicle deceleration is output by in-wheel motors under Medium-intensity braking condition for the sake of recovering the maximum braking ene...

The Hybrid Electric Vehicle Team of Virginia Tech (HEVT) is participating in the 2009 – 2011 EcoCAR: The NeXt Challenge Advanced Vehicle Technology Competition series organized by Argonne National Lab (ANL), and sponsored by General Motors Corporation (GM) and the U.S. Department of Energy (DOE). The goal of EcoCAR is for student engineers to take a GM-donated crossover SUV and reengineer it to...

The objective of this study was to examine the post-thaw effects of three cryoprotective extenders (Tris-fructose-citric acid extender, Tris-glucose-citric acid extender, and lactose extender), three linear freezing rates (-1, -6, and -20 degrees C/min), and three thawing rates (37 degrees C water bath for 120s, 60 degrees C water bath for 30s, and 70 degrees C water bath for 8s) on coyote sper...

This paper describes a power electronic system that, among other possibilities, can be used to charge electric vehicle batteries. A large-signal linear, multirate digital controller for the charging current permits the charger to track and deliver a desired current trajectory for a wide range of loads. This controller simultaneously ensures that the charger draws power from the electric utility...

Hybrid Electric Vehicles (HEVs) are a prominent solution for reducing CO2 emissions from transport in Europe. They equipped with at least two propulsion energy converters, an Internal Combustion Engine (ICE) and one or more Machines (EMs), operated way to exploit synergies achieve fuel efficiency. Because of the variety configurations strategies, use simulation is essential vehicle development ...
