Abstract

A self-recharging electric generator system in communication with an external system, where the external system includes a power source external to the self-recharging electric generator system, and the self-recharging electric generator system includes at least one electric motor configured to receive power from the power source of the external system, at least one generator configured to produce power to be supplied to the external system, and to the at least one electric motor, at least one sensing device configured to be connected with an onboard battery system of the external system, to sense a charge status of the onboard battery system, and a switch device electrically coupled with the at least one sensing device and configured to switch from the power source of the external system to the at least one generator as the source for supplying power to the at least one electric motor.

Claims

1. A self-recharging electric generator system in communication with an external system external to the self-recharging electric generator system, the external system comprising an external power source, the self-recharging electric generator system comprising:

at least one electric motor configured to receive power from the external power source of the external system to start the at least one electric motor;

at least one generator configured to be started by power received from the at least one electric motor, and to produce power to be supplied to the external system and to the at least one electric motor;

at least one sensing device configured to be connected with an external battery system of the external system, to sense a charge status of the external battery system, wherein the external battery system is onboard the external system; and

a switch device electrically coupled with the at least one sensing device and configured to switch from the external power source of the external system to the at least one generator as the source for supplying power to the at least one electric motor in response to a signal relating to the charge status of the external battery system received from the at least one sensing device.

2. The system of claim 1, wherein the external system is an electric vehicle.

3. The system of claim 2, wherein the external battery system includes two or more battery units, and the self-recharging electric generator system is connected with each battery unit and is configured to recharge each battery unit, alternately, to provide a continuous charge to the electric vehicle.

4. The system of claim 2, wherein the sensing device is configured to:

determine a rate of charge for a battery unit of the external battery system of the electric vehicle; and

determine a rate of consumption of the battery unit, to thereby determine a minimum distance traveled before the battery unit requires recharging.

5. The system of claim 1, wherein the external power source comprises an uninterruptible power supply (UPS) battery unit.

6. The system of claim 1, wherein the external power source comprises a rechargeable power supply unit configured to supply power to the at least one electric motor.

7. The system of claim 1, wherein the external power source comprises a lithium ion battery.

8. The system of claim 1, further comprising a housing configured to house the at least one electric motor, the at least one generator, the at least one sensing device, and the switch device.

9. A self-recharging electric generator system in communication with an external system external to the self-recharging electric generator system, the external system comprising an external power source, the self-recharging electric generator system comprising:

at least one electric motor coupled with the external power source and configured to receive power from the external power source; and

at least one generator configured to produce power to be supplied to the external system to continuously charge the external power source, and further configured to produce power to be supplied to the at least one electric motor.

10. The system of claim 9, wherein the external power source comprises an uninterruptible power supply (UPS) battery unit.

11. The system of claim 9, wherein the external power source comprises a rechargeable power supply unit configured to supply power to the at least one electric motor.

12. The system of claim 9, wherein the external power source comprises a lithium ion battery.

13. A self-recharging electric generator system in communication with an external system external to the self-recharging electric generator system, the self-recharging electric generator system comprising:

a battery unit;

at least one electric motor configured to receive power from the battery unit; and

at least one generator configured to produce power to be supplied to the external system when a failure occurs at a main power supply source of the external system, and to supply power to the battery unit for charging of the battery unit.

14. A self-recharging electric generator system in communication with an external system external to the self-recharging electric generator system, the self-recharging electric generator system comprising:

a battery unit;

at least one electric motor configured to receive power from the battery unit;

at least one generator configured to produce power to be supplied to the external system when a failure occurs at a main power supply source of the external system; and

an automatic switching unit configured to switch between the main power supply source and the self-recharging electric generator system, wherein the power produced by the at least one generator is further supplied to the automatic switching unit to perform continuous charging of the battery unit.

15. The system of claim 14, wherein the at least one generator comprises a plurality of generators connected in parallel, and configured to operate in two stages.

16. The system of claim 14, further comprising:

an inverter configured to convert the power supplied from the battery unit; and

a starting device configured to start the self-recharging electric generator system.

17. The system of claim 14, wherein the battery unit comprises an uninterruptible power supply (UPS) battery unit.

18. The system of claim 14, wherein the battery unit comprises a rechargeable power supply unit configured to supply power to the at least one electric motor.

19. The system of claim 14, wherein the battery unit comprises a lithium ion battery.

20. The system of claim 14, further comprising a housing configured to house the battery unit, the at least one electric motor, the at least one generator, and the automatic switching unit.
