Abstract

A compact and lightweight hybrid vehicle power source employs an integrated engine hybrid electric boost power design that operates on a single battery bank for all electrical functions. An integrated flywheel, cooling fan and a single hybrid electric motor drive, engine starter, electromagnetic regenerative braking device and battery charging alternator are combined. The flywheel alternator/starter/hybrid-drive configuration generates electrical power for battery recharging and parasitic loads, rotates the engine for starting, provides boost power for faster vehicle accelerations, provides regenerative braking for faster decelerations, provides inertia for smooth engine operation, and provides pressurized air for forced convection cooling.
