  1. Alternative Energy Sources

  2. Any vehicle that uses two or More Power Sources Gas engine and electric motor What Is a Hybrid Vehicle ?

  3. Examples of Hybrid vehicle’s • Automobiles • Mopeds • Locomotives • Buses • Submarines

  4. The Hybrid System • Gasoline Engine drives the automobile during highway speeds when minimum Horsepower is required • Electric Motor works with the Gasoline Engine while accelerating from a stop and during periods when extra acceleration is required

  5. Hybrid Components • Generator • Only used as an electricity producing component • Batteries • Store Energy to power Electric Motor • Transmission • Drives Vehicle directly from the gasoline engine or electric motor • Gas or Diesel Engine • Electric Motor

  6. ElectricMotors A machine that changes electrical energy into mechanical energy to do work.

  7. Gas Engine A machine that changes chemical energy into mechanical energy to do work. Through the burning of gasoline.

  8. Generator • A machine that changes mechanical energy into electrical energy • It must be turned or driven by an outside source

  9. Regenerative Braking • Traditional Car brakes- the faster a car is going the more kinetic energy it has, the brakes remove the energy and release heat. • Hybrid cars use the electric motor to help stop the car. Acting as a generator it captures the energy lost in braking and uses it to charge the batteries.

  10. Transmission • Take the power from then motor or engine and transfers the power to the wheels. • A mechanical device that is designed to change a vehicles drive wheel speed and torque in relation to the engine speed and torque.• Torque - A turning or rotating force

  11. Honda Insight • 61mpg/city • 68mpg/highway • 3 Cylinder VTEC-E • Integrated [electric] Motor Assist • BEST FUEL ECONOMY OF ANY CAR SOLD IN THE U.S. • $19,080 Base Price

  12. Toyota Prius • 45mpg/city • 52mpg/highway • 4 Cylinder VVT-I • Toyota Hybrid System (THS) • Power Splitter connects motor and generator together for a constant variable transmission • $20,480 Base Price

  13. Hybrid Maintenance • Both Honda and Toyota offer good warranties on there hybrid vehicles. • Insight offers a 8yr/80,000 mile warranty on the power train, electric motor and batteries. A 3yr/36,000 mile warranty on everything else. • The electric motors and batteries shouldn’t require maintenance over the life of the vehicle. • But if the batteries do need to be replaced after warranty it would cost a few thousand dollars. • The brake pads may also last longer on hybrids because of regenerative braking.

  14. Types of Hybrid Vehicles • Parallel • Series

  15. Parallel Hybrid • Uses fuel for the gas engine, and batteries for the electric motor. • Both electric motor and gas engine connect to transmission. • Both power sources can power the transmission simultaneously or individually.

  16. Series Hybrid • Gasoline engine turns a generator which can either charge batteries or supply power to the electric motor. • The electric motor powers the transmission. • This means the gas engine never has a direct connection with the transmission.
