Best ppt on Hybrid cars

  1. 1. Hybrid Cars: How have they improved since introduction? by- Ronak Thakare
  2. 2. Introduction • Definitions • Classification • Electric vs. Internal Combustion • Timeline for Hybrid technology development • The Batteries • Study: Insight vs. Prius • The Future
  3. 3. HYBRID VEHICLE • A hybrid vehicle is one that uses two different methods to propel the vehicle. • A hybrid electric vehicle, abbreviated HEV uses both an internal combustion engine and an electric motor to propel the vehicle. • Most hybrid vehicles use a highvoltage battery pack and a combination electric motor and generator to help or assist a gasoline engine.
  4. 4. What is a hybrid? • Hybrid electric vehicles (HEVs) include both a combustion engine as well as an electric motor. • If we had better batteries, we would not need hybrids at all. • Hybrids can be implemented in many kinds of vehicles.
  5. 5. Global-Warming: Still An Issue. • Hybrids are not zero-emission vehicles. • Will cut down emissions of global-warming pollutants by a third to a half. • Later models may cut these emissions down by even more.
  6. 6. Why hybrids? • 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. • New materials can be implemented.
  7. 7. CLASSIFICATIONS OF HYBRID-ELECTRIC VEHICLES • The types of hybrid-electric vehicles include: – Series – Parallel – Series-parallel designs
  8. 8. CLASSIFICATIONS OF HYBRID-ELECTRIC VEHICLESCLASSIFICATIONS OF HYBRID-ELECTRIC VEHICLES FIGURE 39-3 A drawing of the power flow in a typical series hybrid vehicle.
  10. 10. CLASSIFICATIONS OF HYBRID-ELECTRIC VEHICLESCLASSIFICATIONS OF HYBRID-ELECTRIC VEHICLES FIGURE 39-7 A series-parallel hybrid design allows the vehicle to operate in electric motor mode only or in combination with the internal combustion engine.
  11. 11. Electric Motor • Lots of torque • Zero emissions • Tax breaks • No transmission needed • Starts more efficiently – Can turn off motor when you stop
  12. 12. Gasoline • Higher energy density than batteries – 1,000 pounds of batteries = 1 gallon (7 pounds) of gas • Cheaper initial cost for car – Hybrids are $3500-5000 more • Reliable, more history
  13. 13. Cost Per Mile Electric vs. Gas
  14. 14. Timeline • 1839: First electric vehicle • 1886: Electric powered taxicab in England • 1890-1910: Significant improvements in battery technology (lead-acid, nickel-iron) • 1898: Ferdinand Porsche built a hybrid
  15. 15. Timeline • 1900: Pieper introduced hybrid • 1905: Gas-Electric car • 1970’s: Arab oil embargo; hybrid VW Taxi • 1979: hybrid car built with lawnmower engine • 1991: US Advanced Battery Consortium launched major program to produce “super” battery
  16. 16. Timeline • 1997: Toyota Prius available in Japan • 1999: Honda Insight released in US (70 mpg) • 2000: Toyota Prius available in US • 2002: Honda Civic Hybrid introduced • 2004: Toyota Prius II introduced; Ford Escape Hybrid introduced
  17. 17. The Batteries Behind It All • Early Prius and Insight NiMH D Cells – Stick Arrangement ((
  18. 18. Prismatic Ni-MH • 15% pack volume reduction • 25% pack weight reduction • Less battery module per pack number
  19. 19. Metal Case Prismatic Ni-MH • Improvement – 14% less volume – 40% higher cooling ((
  20. 20. ECU • Electronic Control Unit • Regulates temperature and state of charge • Ensures safe and reliable driving
  21. 21. Study: Battery Usage and Thermal Performance of Prius and Insight • Honda Insight vs. Toyota Prius
  22. 22. Battery Energy and Battery Temperatures
