Self Rechargeable Electric Vehicles {SELF CHARGING TYPE ELECTRIC VEHICLE}

The present invention relates to a self-charging electric vehicle, and more particularly, a generator is mounted on the rear wheel of a vehicle, and the electric energy generated by the generator is continuously charged in a battery to drive a motor to obtain driving force necessary for driving. It's about electric vehicles.

BACKGROUND ART In automobiles, internal combustion engines, including gasoline engines, usually burn fuel in a cylinder and use energy generated at this time as power. In such an internal combustion engine, the exhaust gas discharged after combustion contains finite components such as nitrogen oxides due to combustion and carbon monoxide and hydrocarbons due to incomplete combustion, thereby polluting the atmosphere.

Due to the environmental pollution and the depletion of fossil fuels, researches on automobile engines using alternative energy are actively conducted in each country. Currently, electric vehicles using electric energy have the highest possibility of practical use among automobiles using alternative energy. An electric vehicle has a structure in which a vehicle can be driven by rotating a motor by electric energy supplied from a storage battery instead of a fuel of a gasoline engine.

Some have developed hybrid and rechargeable electric vehicles, but this is still under study. Applicant also has one rechargeable car.

Since a conventional electric vehicle having such a configuration does not have a separate self-charging device, a large amount of batteries must be installed for long driving, thereby increasing the weight of the entire vehicle. In addition, the range of travel that can be driven by one charge is limited, so it is impossible to travel long distance and it takes much time to charge it once. In addition, since charging stations are not yet installed as gas stations, the commercialization of electric vehicles is not much in reality, and it is still under research, and it is used for special purposes in low-speed vehicles only in limited areas.

The present invention devised to solve this problem is equipped with a generator that can continuously generate electric energy, the rear wheel, left, right, two of the vehicle, by continuously charging the electric energy charged in the battery to drive the continuous driving power The objective is to provide a self-charging electric vehicle that can extend its range.
