Science and Technology. Therefore it is highly essential for Electrical Students to
study about the measurement of various Electrical Parameters in a system and the
construction and working of different Instruments used in measurement of such
parameters.

Energy conservation is the effort made to reduce the consumption of energy by

using less of an energy service. Energy can be conserved by reducing wastage and losses,
improving efficiency through technological upgrades and improved operation and
maintenance. Energy Audit is the key to a systematic approach for decision-making in the
area of energy management. The effective use of energy to maximize profits (minimize
costs) and enhance competitive positions, it is necessary to conserve energy. Hence it is
necessary to study energy auditing methods and energy saving opportunities in electrical
system.

standard of living. The Modern Society is so much dependent upon the use of Electrical
Energy that it has become a part of our life. So to have adequate knowledge in Electrical
Power Generation and Transmission, Switch Gear and efficiency associated with them, it
becomes necessary to include this subject.

The world is transitioning to cleaner mobility options with the aim at improving air quality and
reducing dependency on fossil fuels. Electric Vehicles (EVs) have emerged a popular clean
mobility choice to reduce emissions. EVs are powered fully or partially by batteries, they can
help to reduce dependence on fossil fuels also air quality. Tamil Nadu is one of the most
advanced states in India. Tamil Nadu has a highly developed industrial eco-system and is very
strong in sectors like automobiles and auto-components. Many globally renowned companies
have setup their manufacturing facilities in Tamil Nadu. Due the rapid depletion of fossil fuel and
increase in fuel cost, environmental pollution, the shift to clean transport is necessary. This
subject introduced by keeping all the above factors.

OBJECTIVES

1. To learn the environmental impact and history of Electric Vehicles.

2. To understand the concept of Electric Vehicle and its types.
3. To study the configurations of Electric Vehicles
4. To acquire knowledge about Energy Storages, Charging System, Effects and Impacts
