					Hybrid Electric Car: A Promising Technology for a Promising Future for
the Environment

A hybrid-electric vehicle, or HEV, combines an electrical energy storage
system with an occupied means of generating electrical energy, usually
through the consumption of some type of fuel. Each type of HEV has its
own operating quality and chosen design practices, as well as advantages
and disadvantages.

The development of interior ignition engine vehicles, especially in
automobiles, is one of the supreme achievements of modern technology as a
new rising energy saving and environment -friendly vehicle, that’s why
the hybrid-electric vehicles were created to give convenience to every

In the process of creating the hybrid electric car, the most important is
the energy saving and the environmental protection. Wherein nowadays this
are the common problems faced by the society.

Having the hybrid-electric car evolved from the electric car. However,
the main disadvantage of the electric car is that it is mainly dependent
on the batteries. Therefore, has limited range.

First of all, the hybrid electric car was supposed to be an electric
vehicle with batteries for power storage and is also equipped with an on-
board heat engine-powered generator. This means that this type of hybrid
has an extended range.

The heat engine power and the battery power are specifically intended as
an important scheme that constantly modulates the excess between the heat
engine and the battery power systems. This will also depend on the
driving schedule.

Since the beginning of the use of automobiles, electric cars have been
already recognized and conceptualized. Even though the electric power
train is better in various aspects, as an energy source, the battery was
unequal to the superior-energy content, easiness in terms of the
handling, and inexpensive and profuse supplies of motor fuel.

Now, it has almost been a century since the electric car has been
popularly discussed, but recent developments in the HEV technology and
the growing concerns for the environment has revived the drive for an HEV
and this has become a realization today.

We can consider the personal means of transportation as a very important
bond in the economic chain of today’s modern societies and that a private
vehicle appears to be the popular choice.

Electric vehicles are more energy efficient than the contemporary
vehicles wherein the electric vehicles operates at approximately 46
percent of effectiveness, while a contemporary vehicle operates at about
18 percent only.
There are studies that generally concludes that electric cars with
batteries are approximately 10 to 30 percent more efficient with energy
than the usual gasoline cars, depending on the exact assumptions of the
vehicles energy usage and energy chain efficiency.

Certainly, the comparisons of the electric vehicles and the conventional
vehicles are comparisons between an extremely developed power system that
is nearly in the end of its research and development, and the innovative
power system in the beginning stages of the development wherein important
development can be expected as the new technology evolves.

Furthermore, the advantages of electric powered modes of transportation
extends beyond the true outlook of economizing energy. Electric
generation plants can use substitute fuels that are not adaptable to
portable power systems.

Electric vehicles are the definitive alternative fuel vehicles because
their power is taken from the source fuels utilized to produce
electricity. Aside from that, the flexibility of the fuel alone can offer
important useful and economic advantages especially in relation to a
variety of energy resources.

The electric car is truly a promising technology that could transform
one's means of transportation into a far more environmentally type of
commodity. Through this innovation emission controls become more
important, effective and economically beneficial.
