Hybrid Electric Vehicles

Hybrid electric vehicles are automobiles which make use of a combination of conventional propulsion systems and rechargeable energy storage systems (RESS).

The purpose for combining these two different power sources is to achieve improved fuel economy in hybrid electric vehicles compared to the conventional cars and trucks. Then, batteries are just used for support, and limited propulsion needs, without requiring any recharging due to the storage and energy renewal system.

Modern times have seen the mass production of hybrid electric vehicles coming from a number of well known car manufacturers. The reasons why many car producers jump on the green bandwagon are varied. Whether there is a genuine interest in saving energy and not using the planet’s energetic sources, or a smart and "caring" way to attract buyers and thus sell more cars, one cannot be certain. There are three main ways that allow current hybrid electric vehicles to reduce gas consumtion. There is less wasted energy to start with, this means that during idle or low input your battery is charging and then you will no longer have to worry about the under-usage inefficiency that results from a low function rate of the engine.

The modern mass-produced hybrid electric vehicles are able to prolong the charges on their batteries simply through collecting the kinetic energy via the regenerative braking system. Some hybrid electric vehicles use the internal combustion engine (ICE) to create electricity by spinning an electrical generator (quite often this is a motor-generator) to directly supply the electric motor that drives the vehicle or to recharge the battery. Many of the existing hybrid electric vehicles’ capability is to reduce idle emissions by shutting down the internal combustion engine at idle status and restarting it when necessary (this is a start-stop system). The engines of the hybrid electric vehicles are smaller than those of non-hybrid petroleum fuel vehicles. These engines may work at various speeds, thus generating more efficiency.

The making of the hybrid electric vehicles started in the late 1990s and the first ones came from Honda (Honda Insight) and Toyota (Toyota Prius). Even since the beginnings of hybrid electric vehicles they have become widely available to the buyers. The future of hybrid electric vehicles is definitely positive, and this is the forecast by some car makers who consider hybrid electric vehicles a core segment of the automotive market of the future.
