INTRODUCTION RECENT years have seen many different initiatives aimed at bringing about a low-carbon society and it is anticipated that, in the automotive field, HEVs (hybrid electric vehicles) that offer significant improvements in fuel consumption will precede EV (electric vehicles) in becoming the mainstream of future vehicle markets. HEVs achieve low fuel consumption and powerful performance...

Electric-drive vehicles can provide power to the electric grid when they are parked (vehicle-to-grid power). We evaluated the economic potential f two utility-owned fleets of battery-electric vehicles to provide power for a specific electricity market, regulation, in four US regional regulation ervices markets. The two battery-electric fleet cases are: (a) 100 Th!nk City vehicle and (b) 252 Toy...

The steady increase in oil prices and awareness regarding environmental risks due to carbon dioxide emissions are promoting the current interest in electric vehicles. However, the current relatively low driving range (autonomy) of these vehicles, especially compared with the autonomy of existing internal combustion vehicles, remains an obstacle to their development. In order to reassure a drive...

Electric vehicles are by many seen as the cars of the future as they are high efficient, produces no local pollution, are silent, and can be used for power regulation by the grid operator. However, electric vehicles still have critical issues which need to be solved. The three main challenges are limited driving range, long charging time, and high cost. The three main challenges are all related...

Electric vehicle is considered to be the solution for energy crisis and environment pollution in individual transportation. However, electric vehicles are still not competitive with conventional vehicles limited by the driving range with the state-of-art power battery technology. Therefore, energy efficiency is of crucial importance for battery electric vehicles due to the limited stored energy...

This study investigates the tonal high frequency noise characteristics which are present within the cabin of an electric vehicle. As the human ear responds differently to different frequencies of sound and this response varies with age, both the level and the frequency are considered. In addition, the amount of annoyance these sounds will cause for the occupants is a function of the tonality an...

Energy management in vehicles is an important issue because it can significantly influence the performances of the vehicles. Improving energy management in vehicles can deliver important benefits such as reducing fuel consumption, decreasing emission, lower running cost, reducing noise pollution, and improving driving performance and ease of use. According to Mainins (Manins, 2000), each year m...
