Range Extender

Plug-in hybrids which use electricity as their primary energy source also include range-extending generators. Range-extenders can run on gasoline, diesel, or biofuels. CAVS has developed range-extending engine packages for each fuel. A typical range-extender includes a combustion engine, generator, compliant torque coupling, mechanical coupling, and thermal management system.

CAVS’ most recent range-extender package uses an 850 cc engine and PMDC generator to produce over 50 kW of electric power while weighing less than 80 kg. It achieves efficiency (liquid fuel to 300 VDC) of 31.6%.
