Based on the problems caused by today conventional vehicles, much attention has been put on the fuel cell vehicles researches. However, using a fuel cell system is not adequate alone in transportation applications, because the load power profile includes transient that is not compatible with the fuel cell dynamic. To resolve this problem, hybridization of the fuel cell and energy storage device...

Hybrid electric vehicles with significant all-electric range provide a promising alternative to zero emission vehicles (ZEVs) without the problem of the limited range of electric vehicles. Ovonic nickel-metal hydride (NiMH) batteries feature a combination of high power and energy density ideal for ZEV-range hybrid electric vehicles. A series of high-power, highenergy batteries ranging in size f...

In this paper, Plug-in Fuel Cell Electric Vehicle (PFCEV) is considered with dual power sources including Fuel Cell (FC) and battery Energy Storage. In order to respond to a transient power demand, usually supercapacitor energy storage device is combined with fuel cell to create a hybrid system with high energy density of fuel cell and the high power density of battery. In order to simulate the...

Electric-drive vehicles (EDVs), whether based on batteries, engine-electric hybrid, or fuel cells, could make major contributions to the electric utility supply system. Computer-controlled power connections from parked EDVs would provide grid power from on-board storage or generators. Kempton and Letendre conclude that, in the United States, battery EDVs can be cost-e!ective as a source of peak...

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 variable transmission is a new electromechanical energy conversion device structure, which is especially suitable as the driving force distribution device for hybrid electric vehicles. This paper focuses on the power management strategy of hybrid electric vehicles based on an electric variable transmission, and a kind of hierarchical control ideology is proposed. The control strategy i...

Many perceive electric vehicles (EVs) to be ecoenvironmentally sustainable because they are free of emissions of toxic and greenhouse gases to the environment. However, few have questioned the sustainability of the electric power required to drive these vehicles. This paper presents an in-depth study that indicates that massive infusion of EVs to our society in a short time span will likely cre...
