Hybrid cars

  1. 1. Mr. Amey Patel. Mr. Kaustubh Mehta. S. B. M. Polytechnic.
  2. 2. TABLE OF CONTENTS  Introduction  Working Of Hybrid Vehicle  Regenerative Braking  History  Present  Pros & Cons Of Hybrid Vehicles  Scope
  3. 3. 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)
  4. 4. Working Basic Components. Acceleration. City driving. Highway Driving Driving up a gradient.
  5. 5. Regenerative Braking  A regenerative brake is an energy recovery mechanism  Converts Kinetic energy into Electrical form.  While braking, it absorbs 80% of kinetic energy.
  6. 6. 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.  1968-71 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.
  7. 7. Present A 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.
  8. 8. Pros Of Hybrid Systems  Lowered environmental impact.  Less noise pollution.  Increased Efficiency.  Durable & Reliable.  Batteries are ECO friendly.
  9. 9. Cons Of Hybrid Systems  Costly.  Heavy weight of batteries.  Availability of charging stations.
  10. 10. 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.
