AN APPROACH TO ELECTRIC HYBRID
Electric hybrid vehicles are the vehicles in which there is an electric motor which is powered by a battery and works in combination with a conventional internal combustion engine. The major significant of this combination is that it helps in rapid refueling of the vehicles and also offers an extended driving range. There is a wide range of hybrid vehicles which are available in the market, and many are there to be introduced in the coming months. Most of the manufacturers are working upon a new concept of hybrid gasoline vehicles, which are also expected to be introduced in upcoming months.
Basic Principle of HEVs
An internal combustion engine (ICE) and electric batteries are mostly used in HEVs to power electric motors. The charge over the batteries of the HEVs is produced by harnessing kinetic energy generated through regenerative braking. There are some HEVs in which the combustion engine is the main source of generating electricity which is produced due to the mechanical energy of the spinning electrical generator. This electricity can either be used to recharge the battery or to supply power to an electric motor to propel the vehicle. But, the battery electric vehicles use the batteries which are charged by an external source. There is a remarkable feature exhibited by most of the HEVs that is to reduce the idle emissions by the shutting down of the ICE at idle and restarting when it is required. An HEV's engine has a capability to run at different speeds in a more efficient manner due to its smaller size.
Electric Hybrid Cars Electric hybrid cars have brought boom in the industry of automobiles due to their significant features of less gasoline consumption, saving money, and protecting environment from the harsh effects of pollution caused by the automobiles. The demand of the electric hybrid cars is increasing expeditiously because of the increasing price of the gasoline and the increasing pollution. They are composed of plastic and aluminum with a unique feature of reducing the consumption of fuel every day. Electric hybrid cars are also known as the environment friendly cars, as they do not emit large amount of fuel, and their batteries also get recharged easily on their own. The hybrid cars are more economical as compared to that of electric cars, because they do not require any place to be plugged in, as in the case of the electric cars which propel on energy. Also, in order to recharge an electric car, it needs a supply from an outlet which is its major disadvantage, as it becomes difficult to find the areas for the quick fix. As compared to the electric cars, the hybrid cars are more affordable and will keep on becoming cheaper in the coming years. Systems of HEVs The HEVs are compatible to both parallel or series systems but the only difference lies in their propulsion of the power-generating units. On comparing both of them, the parallel configuration is more pliable and potent but is more complex as well as costlier. There are three different types of parallel designs which have been introduced yet. 1) A 300-volt system comprises of an internal combustion engine with a continuous power supply. Its 300-volt electrical motor supplies the difference between engine power and peak power demand. It is bit expensive due to the use of large batteries in its configuration. 2) In a 150-volt system, an electrical motor produces a power less than that of 300-volt system, therefore its internal combustion engine has to be larger to reduce the fuel consumption but the batteries have to be smaller comparatively. 3) There are 42-volt systems which are also known as the "mild hybrids" with a "starter-alternator" located between the engine and transmission for saving energy on automatic shutting off the idle. Hence, the hybrid cars are best to be used in this present era to have a control over the increasing pollution as well as on your pocket
