Power feedback system for electric vehicle

A power feedback system for an electric vehicle, where the electric vehicle has at least a driving motor, at least a first wheel, and at least a second wheel, the first wheel has an axle rotational speed greater than that of the second wheel, and the driving motor is coupled to the second wheel and drives the second wheel to spin, the power feedback system comprising:

• at least a generator coupled to and driven by the first wheel to produce an AC power;
• a charging controller electrically connected to the generator and converting the AC power from the generator into a second AC power, where the charging controller has a first input terminal and a first output terminal, and the first input terminal is electrically connected to the generator;
• a battery module electrically connected to the charging controller for storing the second AC power output from the charging controller, where the battery module has a second input terminal and a second output terminal, and the second input terminal is electrically connected to the first output terminal of the charging controller;
• and
• a current limiting controller electrically connected to the battery module and the driving motor, where a DC power output from the battery module is delivered to the driving motor at a pre-set amperage by the current limiting controller, the current limiting controller has a third input terminal and a third output terminal, the third input terminal is electrically connected to the battery module's second output terminal, and the third output terminal is electrically connected to the driving motor;
• wherein, when the electric vehicle is turned on, the driving motor drives the second wheel to spin;
• as the first wheel turns, the generator is driven to produce the AC power;
• and, as the first wheel's axle rotational speed is greater than that of the second wheel, the generator produces a current greater than the preset amperage from the current limiting controller.
