Abstract

Techniques for electric vehicle systems, and in particular to a vehicle optical charging system and method of use. In one embodiment, a system for vehicle optical charging comprises: an optical charging station configured to transmit an optical signal, the optical charging station comprising a directive element configured to direct the transmitted optical signal; a receiving vehicle comprising an electrical storage unit and a receiver configured to receive the transmitted optical signal, the receiver in electrical communication with the electrical storage unit; wherein the received optical signal enables charging of the electrical storage unit.

First claim

What is claimed is:

1. A system for vehicle optical charging, the system comprising:
an optical charging station that transmits an optical signal, the optical charging station comprising a directive element that directs the transmitted optical signal; and
a receiver that receives the transmitted optical signal, the receiver being in electrical communication with an electrical storage unit of a vehicle and being tunable in accordance with the received optical signal,
wherein the received optical signal enables charging of the electrical storage unit,
wherein the optical charging station transmits another optical signal to gather initial information on an atmosphere through which the optical signal travels and to gather aiming data for the optical signal,
wherein the another optical signal is at lower-power than the optical signal, and
wherein the optical charging station receives a reflected version of the optical signal to produce additional information on rapidly changing characteristics of the atmosphere.

2. The system of claim 1 , wherein the receiver is interconnected to the vehicle and configured to operate in a plurality of states comprising a retracted state and a deployed state.

3. The system of claim 2 , further comprising an actuator interconnected to the receiver and to the vehicle, wherein the actuator is configured to orient the receiver to receive the transmitted optical signal.

4. The system of claim 1 , wherein the receiver is one of an antenna and a PV array.

5. The system of claim 4 , wherein the vehicle is an electrically-powered vehicle.

6. The system of claim 5 , further comprising a controller that determines if the vehicle requires charging.

7. The system of claim 1 , wherein the directive element comprises a station antenna.

8. The system of claim 7 , wherein the optical charging station further comprises a station controller configured to track a position of the receiver of the vehicle.

9. The system of claim 8 , wherein the station controller directs the station antenna to the tracked position of the receiver of the vehicle.

10. The system of claim 9 , wherein the transmitted optical signal is a laser signal.

11. The system of claim 10 , wherein charging is performed while the vehicle is in motion.

12. The system of claim 3 , wherein the optical charging station further comprises deformable mirrors configured to introduce tailored distortions into the optical signal to compensate for atmospheric distortions determined from the information.

13. A method for vehicle optical charging, the method comprising:
determining, by a microprocessor, if an optical charging station is available for charging of a receiving vehicle;
requesting, by the microprocessor, transmission of an optical signal from the optical charging station to a receiver of the receiving vehicle;
orienting, by the microprocessor, the receiver to receive the optical signal;
receiving, by the receiver, the optical signal from the optical charging station, the receiver being in electrical communication with a receiving vehicle electrical storage unit;
receiving, by the receiver, another optical signal, the another optical signal providing initial information to the optical charging station on an atmosphere through which the optical signal travels and providing aiming data to the optical charging station for the optical signal, the another optical signal being transmitted and received at lower power than the optical signal;
reflecting, by the receiving, the optical signal such that the optical charging station produces additional information on rapidly changing characteristics of the atmosphere, and
changing at least one characteristic of the receiver in accordance with at least one of the optical signal and the another optical signal,
wherein the optical signal enables charging of the receiving vehicle electrical storage unit.

14. The method of claim 13 , further comprising selecting, by the microprocessor, a type of optical signal.

15. The method of claim 14 , further comprising operating an actuator interconnected to the receiver and to the receiving vehicle to orient the receiver to receive the optical signal.

16. The method of claim 15 , wherein the receiver is one of an antenna and a PV array.

17. The method of claim 15 , wherein the receiving vehicle is an electrically-powered vehicle.

18. The method of claim 17 , further comprising tracking a position of the receiver.

19. The method of claim 18 , further comprising directing a station antenna to the tracked position of the receiver.

20. The method of claim 19 , wherein the optical signal is a laser signal, wherein charging is performed while the receiving vehicle is in motion, and wherein the actuator is further configured to orient the receiver in at least a pitch and a yaw rotational position.
