Hybrids

• Humans have used the idea of hybrids long before
  the car
• Agriculture
• Animals

3
Hybrids

• Hybrid
• anything derived from heterogeneous sources, or
  composed of elements of different or incongruous
  kinds
• Nature animals, plants
• Mechanics cars, heating/air conditioning systems
• Ideas St. Ignatius
• Cultures United States

4
Hybrids Vehicles

• Vehicle that relies on two or more power sources
  for propulsion.
• Bicycle with a battery assisted motor.
• Sailboat with solar powered engine.
• Automobile with a on board rechargeable energy
  storage system.

5
Hybrid Cars

• Current Format
• Gasoline Engine with electric motor assist.
• Electric Motor power from batteries
• Batteries recharged during braking

6
Hybrid Layout

• Two styles
• Parallel
• Format for most cars. Electric and Gasoline
  Engines can independently power wheels
• Series
• (Diesel) Engine
• Works through
• Electric motor
• Locomotives

7
Hybrid Layout

• Early Ideas
• Separate Electric and Gasoline functions
• Easier to view
• Most cars combine functions in one axle

8
Hybrid Electric Assist

• During high demand, both the Gasoline engine and
  the electric motor provide power to the wheels
  (battery drained).
• During very low demand, electric motor can
  provide sufficient power for motion (Toyota)

9
Hybrid Battery Charge

• During braking or low demand, power from the
  wheels (or gasoline engine) puts power into the
  Electric Motor.
• Electric Motor becomes a Generator.
• Regenerative Braking (common to all current
  hybrids)

10
Hybrid Battery Charge From the Grid

• Current work with hybrids Plug in
• Electric motor advantages low speed, short
  trips.
• No point source of pollution
