PLUG-IN HYBRID PRIUS
  • WHAT
  • Multi-phase project started as a senior design
    project in the Automotive and Manufacturing
    Engineering Technology Department (Fall 2006)
  • Modify a stock Toyota Prius Hybrid with the goals
    of demonstrating increased fuel economy coupled
    with flexible fuel (ethanol blended) capability
    without increasing tailpipe emissions

7
PLUG-IN HYBRID PRIUS
  • Specific Goals
  • Average fuel economy of 100 MPG
  • Operation on E-85 fuel
  • No negative impacts to drivability
  • No increases in stock vehicle emissions level (as
    measured based on drive cycle test measurements)

8
PLUG-IN HYBRID PRIUS
  • Enablers
  • 100 MPG
  • Increased battery pack capacity through use of
    higher energy density chemistries and/or via
    increased pack size
  • Plug-In capability to enable battery pack
    charging when the vehicle is not in use

Although energy gained from the grid is not
free, its equivalent fuel cost can be relatively
low and hence it can greatly improve average
fuel economy.
9
PLUG-IN HYBRID PRIUS
  • Enablers
  • Flexible fuel capability
  • Materials compatibility testing
  • Consideration of fuel pump and injector capacity
    constraints

10
PLUG-IN HYBRID PRIUS
  • Enablers
  • Drivability
  • Placement of battery cells to distribute the
    increased mass within the frame and interior
    constraints
  • Design of enclosures and mounting to reduce
    relative movement between the vehicle and the
    added mass components
  • Close adherence to weight and balance
    constraints.

11
PLUG-IN HYBRID PRIUS
  • Enablers
  • No impact to drive cycle emissions
  • Increased usage of battery capacity over the
    drive cycle (allows electric only operation)
  • Base-lining and emissions lab familiarization for
    repeatability
  • Extensive tailpipe emissions test and measurement

This becomes an optimization problem since other
vehicle systems are effected during engine off
conditions such as catalyst cooling, etc.
12
PLUG-IN HYBRID PRIUS
  • Vehicle Modifications
  • After baseline testing for fuel economy,
    emissions and drivability, the vehicle will be
    modified with a number of enhancements
  • The next few slides show the anticipated
    progression of modifications

13
FLEXIBLE FUELED VEHICLES
  • Ability to Use ANY Blend of 0 to 85 Ethanol
  • Larger Fuel Injectors
  • Some Different Fuel System Materials
  • Some Vehicles Use a Special Sensor
  • Others Let the Computer Learn the Type of Fuel

In-Line Fuel Sensor

22
E-85 HYBRID2006 Toyota Prius
Insert flex-fuel kit to run on ethanol. Material
compatibility testing will be done to see if
ethanol corrodes or erodes the components of the
fuel system, such as the fuel rail and fuel pump.
