1. Alternative Energy Sources

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

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. Electric Motors 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.
