With the rise in the price of gasoline, more and more people are taking interest in electric vehicles as means of transport. Another major advantage of electrically operated vehicles is that these vehicles offer pollution free means of transportation. Therefore even if 70% of people start using an electrically powered vehicle, we will be free of global warming caused by emission of gases like CO and CO2. There will be almost no instances of cancer caused by pollution.
Electric vehicles are more energy efficient than the contemporary vehicles wherein the electric vehicles operates at approximately 47 percent of effectiveness, while a contemporary vehicle operates at about 19 percent only.
But the electric car which can truly replace a traditional car is still in the conceptual stage as the electric vehicle would need continuous electric power from the batteries. The major disadvantages of present day electric cars are the time period required for recharging the batteries and their limited range
Now, it has almost been a century since the electric car has been popularly discussed, but recent developments in the hybrid electric vehicles technology and the growing concerns for the environment has revived the drive for an hybrid electric vehicles and this has become a realization today
Due to this problem of recharging batteries, a new type of design conceptualized in the minds of researchers and they came out with a solution. The researchers have put forward a new electrical vehicle fitted with on board electric power storage system and means of generating power. The generated power would be stored in the storage system and would be used to drive the vehicle. This new type of vehicle is called hybrid electric vehicle or HEV.
The present day storage system in hybrid electric vehicle comprises of stack of lead acid batteries as these can be charged in parallel with the load. The generating system consists of electric generator powered by internal combustion engine.
Researchers are optimistic about the performance of the hybrid vehicles. They are sure that the hybrid electric vehicle or HEV will be far more fuel efficient than the traditional vehicle powered by internal combustion engine.
