Cars or vehicles are the dominant modes of transportation in the modern world and different cars are powered by different resources to ensure their efficiency. When we say hybrid cars or hybrid vehicle, it is used to describe a vehicle which functions with the help of two or more power resources which are compulsory for its working. These multifarious power sources which serves as instruments its functioning include internal fuel cell or internal combustion engine, with an on-board rechargeable energy storage system or better known as RESS.



It is significant to realize that one of the prevalent demerits of any fuel-run vehicle is its emission and to much carbon emission contributes for increase of pollution levels which greatly affects not only the surrounding environment but also to us- human beings

In simpler viewpoint, when we environmental protection is considered, hybrid vehicles are more often chosen as it has been proven through extensive studies that the level of emission in case of hybrid vehicles is significantly low compared the emissions produced by typical internal combustion engine vehicles and in the face of continually rising fuel prices, these hybrid vehicles are useful in maintaining better fuel economy.

Why the use of hybrid vehicles is of that advantage? They have enormous battery storage capacity which makes them to capable for storing recaptured energy. In addition, the hybrid cars are categorized as extremely ideal for running on modern roads as they give suitable conditions to run under high traffic road networks.

Why is that so?Precisely because the working of the diesel engine or gasoline is terminated during idle periods or traffic stops and during these conditions, they tend to prevent the unnecessary loss of fuel resources. Aside from environmental pollution, noise pollution is also an increasing problem and in this case hybrid cars have an edge over other kinds of cars as the level of nose emission in these cars is also quite low.

There are many kinds of hybrid vehicles. The Battery Electric Vehicles or BEVs may at times posses such batteries which can be recharged even during the vehicle is in motion. The Hybrid Electric Vehicles or HEVs are the most prominent among the various hybrid cars and in fact the term hybrid vehicle is commonly utilized to mean merely Hybrid Electric Vehicles.

These hybrid electric vehicles have internal combustion engines, diesel engines run by various fuels or gasoline apart from having electric batteries to boost the electric motors.
