  • Dual motor axle-driven generator system for electric vehicles
    Patent number: 6886647
    Abstract: A dual motor axle driven system for powering a vehicle. A first battery pack provides power to a first electric motor and a second battery pack provides power to a second electric motor. A generator is connected to a differential gear train and the first and second battery packs. Rotation of the wheels transfers rotational kinetic energy to the differential gear train for conversion into electrical energy by the generator for recharging the first and second battery packs while the vehicle is in motion. A tachometer measures a revolution speed of a drive shaft. The vehicle is powered by the first electric motor when the measured revolution speed of the drive shaft is less than a threshold value and by both electric motors when greater than a threshold value. The generator recharges the second battery pack when the vehicle is powered by the first electric motor and vice versa.
