Plug-in Hybrid Electric Vehicle Project

Background - Prof. Dean Edwards and the Dept. of Chemical Engineering at UI is developing high performance lead acid batteries for use in the automotive industry with a focus on low performance to cost ratio. Two years ago, a military humvee on loan was converted to electric power by UI students, however the vehicle has since been taken back by the US Army, and Dr. Edwards is without a functioning vehicle to test batteries. Since then a space frame from an old project has been pulled from storage, and several of the primary components for a functioning vehicle have been collected.

Our Goal - The focus of this project is to provide only the base platform needed for a functioning, driving plug-in hybrid electric vehicle for use in testing the lead acid batteries being developed by Prof. Dean Edwards.

Target Specifications

  • provide a functioning electric vehicle platform
    • source an appropriate off-the-shelf suspension
    • make necessary modifications to the frame to integrate sourced suspension
    • integrate the provided 150 kW motor, transmission, and power electronics unit into the frame
    • integrate the provided motorcycle engine and alternator into the vehicle as a functioning autonomous range extender
      • develop an information flow diagram and state machine to model the autonomous function of the range extender
    • integrate the necessary components remaining required for a driving vehicle: steering, brakes, seats, and other driver controls

Final Product

  • fully functioning electric vehicle
  • manually functioning range extender with necessary logic to make autonomous
  • specifications:
    • 150 kW electric motor
    • 10:1 single speed transmission
    • 12 kW-hr battery pack
    • Yamaha R6 Engine coupled to a custom Fischer Alternator
    • fully independent double wishbone suspension from '89 Toyota Supra

Future Work

  • Meet requirements for vehicle to be street legal
