The increase in ‘interior ignition’ vehicles, particularly in automobiles, is among the most remarkable examples of innovative technological advances. The energy-saving and eco-friendly hybrid-electric vehicles have been designed for the convenience of every human being on the earth.

While manufacturing hybrid electric cars, great care has been taken to address energy-saving and environmental protection concerns, which are the most common problems faced by the society these days. The hybrid-electric car is an off-shoot of the electric car.

However, the main disadvantage of the electric vehicles is that running of the vehicle is mainly dependent upon batteries and therefore, has very limited scope. Initially, the hybrid electric vehicle was designed to be an electric vehicle with batteries for storage of power and in addition, it was provided with an on-board internal combustion engine.

This indicates that this type of hybrid vehicle has a wider scope than the usual electric car. The ‘heat bhp’ and the power of the battery are specifically designed as an important feature in order to constantly adjust the overload between the engine and the battery power systems.

This can also depend upon the driver’s driving schedules. Even when the automobiles were first introduced; the concept of electric cars had already been visualized. Electric powered train is excellent in many aspects. Initially the battery was no match to the internal combustion engine as a power source. Back then, high-quality energy content such as gasoline is cheaper and easily available.

Although the electric automobiles have been talked about since hundred years, the latest developments in the hybrid electric vehicle (HEV) technology and the increased apprehensions about the environment have renewed the interest for hybrid electric vehicles. People have started realizing the usefulness of hybrid electric vehicles nowadays.

In the modern days, people generally prefer to own vehicles instead of depending upon public transport. Electric cars are more energy efficient than the conventional automobiles. While electric vehicles run at around 46% efficiency, the latest models of conventional cars operate only at 18%.

Many research studies have established that electric cars run by batteries are around 10 to 30 percent more energy-efficient than the normal gasoline-powered cars, based on the use of energy by the vehicles and the quality of power.

The comparison between the electric vehicles and the traditional gasoline-powered vehicles is, in fact, a comparison between an extraordinary power system developed through R&D efforts and the unique power program developed in the initial stages. In other words, the latest electric vehicle technology is the result of sustained research efforts over the years.

Moreover, the advantages of electric vehicles extend beyond energy saving potential. The plants generating electricity can substitute fuels that are not flexible enough to adapt to portable power systems. Another advantage with electric vehicles is that the flexibility in the choice of power sources, which translate into reasonably good ‘economic benefits’.

On the whole, the technology based on which electric vehicles have been designed shows great potential for further developments that can provide people with energy-efficient, clean ,eco-friendly and affordable electric vehicles.
