Abstract

An apparatus, system and method for autonomous power generation and recharging in electric vehicles (EVs) enhance the energy sufficiency of EVs by enabling EVs to autonomously generate electricity during both motion and stationary conditions, reducing reliance on external charging stations. In some examples, a flywheel-based energy generation system stores rotational energy and transfers it to a generator for electricity production. Through the features such as flywheels with weight control balls, gear-based or gearless configurations, and optional wind-capturing blades, the system maximizes autonomous power generation and energy conversion.

Claims (39)

1. A power generation and recharging apparatus for a vehicle, comprising:

at least one generator connected to a vehicle battery; and

at least one flywheel coupled with the at least one generator and configured to provide rotational energy,

wherein the at least one generator converts the rotational energy into electricity, which is stored in the vehicle battery or supplied to a traction motor for vehicle propulsion based on a user selection,

wherein the at least one flywheel further includes a weight control ball mounted at an outer edge of the at least one flywheel to increase centrifugal force during rotation, and

wherein the weight control ball is made of carbon, metal, or a combination thereof.

2. The apparatus of claim 1 , further comprising at least one gear configured to transmit the rotational energy in the at least one flywheel to the at least one generator,

wherein the at least one gear is located between the at least one flywheel and the at least one generator.

3. A power generation and recharging apparatus for a vehicle, comprising:

at least one generator connected to a vehicle battery;

at least one flywheel coupled with the at least one generator and configured to provide rotational energy;

at least one gear; and

at least one electric motor configured to initially rotate the at least one flywheel,

wherein the at least one generator converts the rotational energy into electricity, which is stored in the vehicle battery or supplied to a traction motor for vehicle propulsion based on a user selection,

wherein the at least one gear comprises a first gear, a second gear, and a third gear, the first gear having a lager diameter than that of the second gear or the third gear,

wherein the first gear is coupled with the flywheel, and is engaged with and driven by the at least one electronic motor, and

wherein the second gear and the third gear, being meshed with the first gear, are coupled with the at least one generator maintaining a uniform rotational speed (RPM).

4. A power generation and recharging apparatus for a vehicle, comprising:

at least one generator connected to a vehicle battery;

at least one flywheel coupled with the at least one generator and configured to provide rotational energy; and

at least one gear,

wherein the at least one generator converts the rotational energy into electricity, which is stored in the vehicle battery or supplied to a traction motor for vehicle propulsion based on a user selection,

wherein the at least one generator comprises a first generator and a second generator, and

wherein the at least one gear includes a second gear and a third gear, ratios and sizes of the second gear and the third gear being configured to accommodate the first generator and the second generator respectively.

5. The apparatus of claim 2 , wherein the at least one gear is modularly designed to be separately mountable onto the at least one flywheel.

6. The apparatus of claim 2 , wherein the at least one gear and the at least one flywheel are coupled to one another as an integrated assembly.

7. A power generation and recharging apparatus for a vehicle, comprising:

at least one generator connected to a vehicle battery; and

at least one flywheel coupled with the at least one generator and configured to provide rotational energy,

wherein the at least one generator converts the rotational energy into electricity, which is stored in the vehicle battery or supplied to a traction motor for vehicle propulsion based on a user selection, and

wherein the at least one flywheel is initially rotated by an external input and is coupled with a spring assembly that uses spring tension to continuously rotate the at least one generator.

8. The apparatus of claim 1 , further comprising at least one blade configured to rotate the at least one flywheel by utilizing wind energy,

wherein the at least one blade is adjustable in size and angle, and the at least one blade further includes a weight control ball mounted at an outer edge of the at least one blade.

9. The apparatus of claim 1 , further comprising an inverter or a converter configured to process a conversion of the electricity generated by the at least one generator and store the electricity in the vehicle battery.

10. The apparatus of claim 3 , wherein the at least one electric motor and the at least one generator continue generating power after a vehicle ignition is turned off, and is controlled wirelessly through a power control device, using a vehicle key or a mobile device.

11. The apparatus of claim 1 , wherein the apparatus is installable either inside or outside the vehicle.

12. The apparatus of claim 1 , further comprising at least one electric motor, wherein the at least one electric motor and the at least one generator continue generating power after a vehicle ignition is turned off, and is controlled wirelessly through a power control device, using a vehicle key or a mobile device.

13. The apparatus of claim 4 , further comprising at least one electric motor, wherein the at least one electric motor and the at least one generator continue generating power after a vehicle ignition is turned off, and is controlled wirelessly through a power control device, using a vehicle key or a mobile device.

14. The apparatus of claim 7 , further comprising at least one electric motor, wherein the at least one electric motor and the at least one generator continues generating power after a vehicle ignition is turned off, and is controlled wirelessly through a power control device, using a vehicle key or a mobile device.
