Hybrid cars p pt.

  1. 1. Mr. Amey Patel.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. 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. 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.
  8. 8. Pros Of Hybrid Systems Lowered environmental impact. Less noise pollution. Increased Efficiency. Durable & Reliable. Less Maintenance.
  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.
