Chapter 1: Introduction

Background of the Study

In the early days, cars used generators rather than alternators to power the vehicle's electrical system and charge the battery. That's not the case anymore. As automotive technology evolved, so did the need for more power. Generators produce direct current, which travels in one direction, as opposed to the alternating current for the electricity in our houses, which periodically reverses directions. As Tesla proved in 1887, alternating current became more attractive as it generates higher voltage more efficiently, something necessary in contemporary automobiles. But car batteries can't use AC power since they produce DC power. As a result, the alternator's power output is fed through diodes, which convert the AC power to DC power.

Purpose of the Study

This paper presents a review ofthe recent research on PHEVs. The review encompasseshistorical and ongoing research into the design andperformance of light-duty PHEVs. The emphasis will beon developments in the past 10 years, although thesedevelopments will be placed within historical context. Theimpacts of PHEVs on petroleum consumption, the electricgrid, criteria and carbon emissions are summarised. The state of the art of PHEV production and demonstration vehicles is described, and finally a set of research needs forPHEVs is proposed.

Problem Statement

The transportation energy has been particularly resistant to diversification of its energy inputs toward more sustainable energy sources. A device will be crucial for regulating the power output of an electrical generator in motor vehicles.

Significance of the Study

The electric motor on a motor vehicle is very sophisticated. Advanced electronics allow it to act as a motor as well as a generator. For example, when it needs to, it can draw energy from the batteries to accelerate the car. But acting as a generator, it can slow the car down and return energy to the batteries.

Generator: The generator is similar to an electric motor, but it acts only to produce electrical power. It is used mostly on series hybrids (Romm, 2006).

Batteries: The batteries in a motor vehicle are the energy storage device for the electric motor. Unlike the gasoline in the fuel tank, which can only power the gasoline engine, the electric motor on a motor vehicle can put energy into the batteries as well as draw energy from them. ·Transmission - The transmission on a motor vehicle performs the same basic function as the transmission on a conventional car. Some hybrids, like the Honda Insight, have conventional transmissions. You might wonder why anyone would build such a complicated machine when most people are perfectly happy with their gasoline-powered cars (Romm, 2006). The reason is twofold: to reduce tailpipe emissions and to improve mileage. These goals are actually tightly interwoven.
