Electric Vehicle Hybrid Power Train 730254

With the goal of reducing the high current peaks which occur in lead-acid batteries used for electric vehicles, a new power train incorporating an inertial storage device coupled to a continuously running electric motor has been designed. The power train consists in part of an electric motor designed for efficient operation over a narrow speed range. Once activated, the motor runs continuously even though the automobile is stopped; during the rest periods the motor stores energy in a kinetic device which acts as an energy load leveler. Such an electric motor-inertia hybrid power train has several advantages: high-power output capability, all mechanical regenerative braking, extended battery life, increased electric motor efficiency, and elimination of expensive solid-state motor controllers.
