TABLE OF CONTENTS Introduction Working Of Hybrid Vehicle Regenerative Braking History Present Pros & Cons Of Hybrid Vehicles Scope
Introduction. HYBRID means combination of two. VIZ. I.C. Engine and Electric Motor. Hybrid Electric Vehicles (HEV’s) Plug-in Hybrid Electric Vehicles (PHEV’s)
Working Basic Components. Acceleration. City driving. Highway Driving Driving up a gradient.
Regenerative Braking A regenerative brake is an energy recovery mechanism Converts Kinetic energy into Electrical form. While braking, it absorbs 80% of kinetic energy.
History 1st hybrid car was made by Porsche in 1898. A 3.5 horsepower in which the small gasoline engine was mated to an electric motor in 1900. In 1916, Woods claimed that their hybrid reached a top speed of 35 mph and achieved fuel efficiency of 48 mpg. Dr. Baruch Berman, Dr. George H. Gelb and Dr. Neal A. Richardson developed, demonstrated and patented the Hybrid Power train. In 1976, General Electric was chosen to construct a parallel-hybrid sedan, and Toyota built its first hybrid.
PresentA number of cars are launched after year 2000 listed as follows: Toyota Prius (4 Door Sedan). Honda civic hybrid. Ford hybrid escape (1st hybrid SUV). Many of major automakers like Toyota, Lexus, Porsche, Mercedes, Honda etc are launching hybrid models in the market.
Pros Of Hybrid Systems Lowered environmental impact. Less noise pollution. Increased Efficiency. Durable & Reliable. Less Maintenance.
Cons Of Hybrid Systems Costly. Heavy weight of batteries. Availability of charging stations.
Scope Regenerative braking actually makes city driving more economical than on the highway. Fuel efficiency is greatly increased (twice). Emissions are greatly decreased. Dependency on fossils fuels can be decreased. Hybrids can be run on alternative fuels as well. Concern for environment is increasing among people.
