Abstract
The world's first practical Electric Vehicle (EV) was built in Britain by Robert Davids. The first gasoline-powered automobile did not appear until 1885, nearly twelve years later.). After that, however, battery technology stalled, while oil was cheap and abundant. Thus the internal combustion engine (ICE) came to rule the automotive world. Time and time again people has shown interest in EV, especially since the 1973's crises
The EV system is an integration of vehicle body, electric propulsion, energy storage battery, and energy mangment. Of capital importance is energy storage unit, electric motor, and control system. Hybridization of the automotive drivetrain attempts to combine the low emissions of electric automobiles with the extended range of gasoline engines. A Hybrid Electric Vehicle (HEY) increases the fuel economy and decreases the emissions of the system when compared to a vehicle functioning only on a gasoline engine. Three main structures are established in HEY: series hybrid,
parallel hybrid, and series parallel configuration.
The battery is the most important part in an HEY. Energy density, power density, cost and other battery characteristics has been studied in the last ten years. The cost analysis of HEY in the last ten years shows that the HEY is much expensive comparable with conventional vehicle cost.
Selecting the best motor for a specific application requires consideration of many factors, such as weight, efficiency, and cost. HEY could have one of the four types of traction motors: DC (conventional motors), AC induction motor (IM),' switched reluctance motor (SRM), and AC permanent magnet synchronous motor (PMSM).
A comparison study is performed for all motor types to select the best one for the HEY applicatioru.. The comparison performed for weight, volume, noise and efficiency. The PMSM have to be the best selection for electric and hybrid electric vehicle (HEY).
In the mid 1980's the direct torque control (DTC) was introduced for induction motor. In the 1990's, DTC for PMSM was developed. Compared with Rotor Field Oriented
