Compact range extender

  • 13-Feb-2012 03:18 EST

FEV and KSPG have developed a compact range extender that has the potential to be universally mounted in electric vehicles. The system includes FEV’s Full Engine Vibration Compensator (FEVcom), which enables the system to maintain properties such as reduced noise, vibration, and harshness. The plug-and-play module (a 0.8-L V2 engine) is suited for rear-end underfloor installation. Active roll moment compensation and a vertical crankshaft provide low vibration excitation. Specific fuel consumption at best point is 245 g/kW·h (0.40 lb/hp·h) at 2500 rpm, Euro 6. The permanent electric motor output is 30 kW at 4500 rpm. Module weight is 62 kg (137 lb) without the exhaust system. Use of the range extender will enable propulsion system designs using smaller batteries, thus reducing cost and overall weight of the vehicle.
