An electric vehicle chargeable by wind energy, the electric vehicle comprising:
- an air inlet that is formed in the front of the electric vehicle configured to travel by rotating a wheel by an electric motor to allow wind to flow in during traveling;
- a turbine that is formed at a rear end of the air inlet and rotated by wind power;
- a power generation unit that includes a rotor coupled to a rotating shaft extended from the turbine and a stator disposed in a ring shape on the outside of the rotor and generates power by rotation of the rotor;
- a power supply unit that converts power from the power generation unit into a chargeable voltage to charge a battery and supplies a driving voltage from the battery to the electric motor;
- a controller that electrically connects the battery and the electric motor through an electrical system and controls charging from the power generation unit to the battery;
- and
- a sensor unit including a wind speed sensor formed on the front of the electric vehicle to measure wind speed during traveling, and a rain sensor to measure rainfall during a rainy season,
- wherein the air inlet includes an air inlet path formed to be recessed in a center or both sides of a front lower portion of the electric vehicle, and an opening/closing port formed in the air inlet path and having an aperture structure to open/close the air inlet path, and
- wherein when a measurement value above a certain level is detected by the wind speed sensor, the controller operates the opening/closing port to open the air inlet path,
- wherein when rainwater inflow into the air inlet path is detected by the rain sensor, the controller operates the opening/closing port to close the air inlet path,
- wherein when the rotating shaft rotates at a preset speed or higher according to a rotation speed thereof, the controller controls the rotation speed of the rotating shaft by controlling a degree of opening/closing of the opening/closing port,
- wherein a semicircular brake pad is coupled to the rotating shaft, and when the rotating shaft rotates excessively, the controller controls the brake pad to reduce the rotation speed of the rotating shaft,
- wherein a discharge hole is formed on a bottom surface of the air inlet path at a front or rear end of a blade of the turbine,
- wherein an exhaust port communicating with the air inlet path is formed, and an auxiliary blade is formed at a rear end of the blade to form a double blade structure, and
- wherein the exhaust port is provided with a damper and a return induction path to re-direct air through a pipe to an upper side surface or a lower side surface of the auxiliary blade.
