INTRODUCTION

To minimize the greenhouse effect caused by emission of CO2, many automobile manufacturers are developing battery-powered automobiles that typically use re- chargeable lithium polymer (or ion) batteries. However, the future of these battery-powered electric cars is less than certain.

This presentation will present a new design concept for an alternate electric car – On-Line Electric Vehicle (OLEV).

OLEV draws its electric power from underground electric coils without using any mechanical contact stations. The infrastructure cost of installing and maintaining OLEV is less than those required for other versions of electric vehicles.

Existing technology in India (TRAM)

▪ A tram (also known as a tramcar ;trolley car) is a rail vehicle which runs on tracks along public urban streets and also sometimes on separate rights of way. Trams powered by electricity, which were the most common type historically, were once called electric street railways. Trams also included horse car railways which were widely used in urban areas before electrification reached the world.

▪ Trams may also run between cities and/or towns (for example, interurban, tram-train), and/or partially grade separated even in the cities (light rail). Trams very occasionally also carry freight.

Future Technology (OLEV)

▪ The Online Electric Vehicle (OLEV), developed by the Korea Advanced Institute of Science and Technology (KAIST), is an electric vehicle that can be charged while stationary or driving, thus removing the need to stop at a charging station.

▪ Likewise, an OLEV tram does not require pantographs to feed power from electric wires strung above the tram route.

Differences between TRAM and OLEV

OLEV

▪ OLEV is a groundbreaking technology that accelerates the development of purely electric vehicles as a viable option for future transportation systems be they personal vehicles or public transit.

▪ This is accomplished by solving technological issues that limit the commercialization of electric vehicles such as price, weight, volume, driving distance, and lack of charging infrastructure.

TRAM▪ Most trams today use electrical power,

usually fed by an overhead pantograph; in some cases by a sliding shoe on a third rail or trolley pole.

▪ They may have several power systems. Another power source is diesel oil; a few trams use electricity in urban streets, and diesel in more rural environments.

▪ Steam, petrol (gasoline), gas and draft animals have historically been used as power sources.

Advantages of OLEV over TRAM

▪ They are environmentally friendly.

▪ They produce no emissions from the tailpipe of the vehicle but the electric motor itself may produce some.

▪ They are both energy efficient, a majority of the “fuel” used is converted into energy via power to the wheels.

▪ Additionally, they have some performance benefits; electronic vehicles can offer smooth and quiet acceleration.

▪ The reduced demand for fossil fuels can help reduce our dependence on foreign energy sources.
