ELECTRIC VEHICLE CAPABLE OF FEEDING BACK ENERGY

摘要

An electric vehicle capable of feeding back energy comprises a frame, wheels (2, 10), axles (11A,11B), a motor (1) installed on the axle and an accumulator (8) providing power for the motor. A set of chain wheels or gears is installed on a flywheel (3) of a rear axle (11A), and a permanent magnet AC generator is driven to generate electricity by the engagement of a chain (4) or gear with a chain wheel or gear on a shaft of the permanent magnet AC generator (5). An output winding of the permanent magnet AC generator is connected with a detector, an intelligent controller, a power source processing circuit and a motor controlling circuit (6). The detector is connected with the motor controlling circuit, the motor and the accumulator, and an accumulator output lead is connected with the motor. When the electric vehicle regularly runs, an internal combustion AC generator set assembled in the electric vehicle provides power for the electric vehicle, and if the speed per hour reaches 20 kilometers, the generated energy of a self-generator has excess electric energy for charging the accumulator.
