The fleet of electric vehicles is systematically growing. Many passenger car manufacturers are already reporting that after 2030, equipped with propulsion will account for half the models produced. Vehicles an drive include: battery-powered vehicles, hybrid and fuel cell vehicles. Over years, these have undergone constant change. aim this paper was to review trends in development pure plug-in
Executive Summary Electric-drive vehicles can become an important resource for the California electric utility system, with consequent air pollution, system reliability, and economic benefits. We refer to electric power resources from vehicles as "Vehicle to Grid" power (V2G). The economic value of some forms of V2G appear high, more than enough to offset the initially higher costs of electric-...
As electric vehicles become promising alternatives for sustainable and cleaner energy emissions in transportation, the modeling and simulation of electric vehicles has attracted increasing attention from researchers. This paper presents a simulation model of a full electric vehicle on the Matlab-Simulink platform to examine power flow during motoring and regeneration. The drive train components...
This chapter focuses on some new definitions and methodologies of electric drives that are facing new challenges raised by alternative fuel vehicles. It starts with the objectives, fundamentals, and current research issues of alternative fuel vehicles based electric drives, before moving on to new definitions of unified modeling of the entire electric drive system and design of the proposed DC ...
greenhouse gas emissions, and the low carbon fuel standard. • Electric drive technology has advanced in performance and reduced in cost, with much improvement in electric motors and power electronics and with high-performance lithium-based batteries now on the cusp of volume production. • The dramatic rise in crude oil and gasoline prices in 2008 spurred a consumer shift toward more efficient v...
In this paper, a comparison concerning electric traction drives for passenger cars is given. Electric traction drives presently available on the market are analyzed and future developments are described. Two main classes of such drives are presented: centre drives (like presently known from hybrid cars) and wheel-hub drives (which are still in the research and development phase). The wheel-hub ...
