Abstract:
1. A dual motor axle driven system for powering a vehicle, said system comprising: a) a first electric motor for driving wheels of the vehicle; b) a second electric motor for selectively driving the wheels of the vehicle; c) a first battery pack coupled to provide power to said first electric motor; d) a second battery pack coupled to provide power to said second electric motor; and e) a generator connected to a differential gear train of the vehicle and to both said first and second battery packs whereby rotation of the wheels of the vehicle transfers rotational kinetic energy to the differential gear train for conversion into electrical energy by said generator for recharging said first and second battery packs while the vehicle is in motion and thereby increasing the distance the vehicle is able to travel before requiring recharging of said first and second battery packs, wherein said second battery pack is coupled to provide power to said first electric motor when said first battery pack requires recharging.
