Extended Range Electric Vehicle Concept Based on a Dodge Caliber to be Unveiled by FEV

FEV, Inc., (FEV) a leading developer of advanced powertrain and vehicle technologies, announced today that it will show a range-extended electric vehicle (ReEV) with plug-in capability based on the Dodge Caliber platform at the 2009 SAE World Congress. FEV's internal development project is designed to demonstrate the company's full spectrum of capabilities in hybrid engineering. The announcement was made by Dr. Joachim Wolschendorf, CTO and vice president of the Vehicle and Drivetrain Engineering Division of FEV, Inc.

"FEV believes that to provide the most value to our customers, we must continue to develop innovative technologies and capabilities within our own walls, conceiving and developing projects that our customers will need now and in the future," said Wolschendorf. "This ReEV concept vehicle has been developed as an internal R&D project, and gives us an opportunity to show our capabilities. We are also using this vehicle to evaluate different options for the engine/generator unit, and the associated calibration strategies."

The Caliber ReEV concept is one of several new hybrid vehicle technologies that are being developed in FEV's recently completed Hybrid and Electric Vehicle Development Center in Auburn Hills, Michigan.

The ReEV propulsion system was developed entirely by FEV, including:

  • Performance modeling and simulations
  • Component selection and procurement
  • Design, analysis and packaging
  • High Voltage system architecture, development and integration
  • Hybrid controls and powertrain development and testing
  • Complete vehicle integration
  • Vehicle exhaust and evaporative emission calibration
  • Overall vehicle calibration, testing and validation
  • NVH optimization

The ReEV propulsion system employs a 1.0L, 3-cylinder, 4 valve engine that is mated to a UQM PP75 generator that provides 41kW of continuous power in extended-range mode, with a peak power of 75kW. The energy storage system consists of a 20 kW-h liquid-cooled Lithium Ion battery pack that operates at 346V, with a Delphi DC/DC converter. A UQM PP125EX traction motor powers the wheels.

Performance statistics for the demonstrator vehicle include:

  • All-Electric Range - 40 miles
  • 0 - 60 mph time - 8.3 seconds
  • Top Speed - 84 mph
