Abstract

A vehicle and a vehicle battery charging system are disclosed. The vehicle charging system includes a parking structure having solar collector. The solar collector is configured to collect and concentrate solar energy. The concentrated solar energy is then transferred to a solar panel located on the vehicle in order to charge a battery of the vehicle.

Claims

1. A vehicle battery charging system comprising:

a parking structure having a solar collector configured to,

collect and concentrate solar energy, and

direct the concentrated solar energy to a solar panel that is rigidly affixed to a vehicle parked within the parking structure in order to charge a vehicle battery; and

a controller programmed to, in response to a change in focus direction of the concentrated solar energy, adjust the position of the vehicle based on the time of day to compensate for movement of the Sun such that the concentrated solar energy remains directed to the solar panel.

2. The vehicle battery charging system of claim 1, wherein the solar collector includes at least one Fresnel lens configured to concentrate and direct the solar energy to the solar panel located on the vehicle.

3. The vehicle battery charging system of claim 1, wherein the controller is programmed to adjust the position of the vehicle in response to seasonal differences in the position of the Sun.

4. The vehicle battery charging system of claim 1, wherein the vehicle battery charging system further comprising a shading device that is configured to cover the solar collector when activated in order to prevent solar energy from entering the solar collector and wherein the controller is programmed to activate the shading device in response to an overheating warning signal.

5. The vehicle battery charging system of claim 1, wherein the solar collector directs the concentrated solar energy to the solar panel via at least one fiber optic cable.

6. The vehicle battery charging system of claim 1, wherein the solar collector collects solar energy from a surface area that is larger than a surface area of the solar panel.

7. The vehicle system of claim 1, wherein the solar collector is located on a canopy of the parking structure.

8. A method comprising:

collecting and concentrating solar energy with a solar collector located on a parking structure;

directing the concentrated solar energy to a solar panel that is rigidly affixed to a vehicle parked within the parking structure to charge a battery; and

in response to focus direction changes of the concentrated solar energy corresponding to seasonal Sun position differences, adjusting vehicle position such that the concentrated solar energy remains directed to the solar panel.

9. The method of claim 8, wherein the solar collector includes at least one Fresnel lens configured to concentrate and direct the solar energy to the solar panel located on the vehicle.

10. The method of claim 8, wherein a controller is programmed to adjust the position of the vehicle based upon time of day in order to compensate for movement of the Sun such that the concentrated solar energy remains directed to the solar panel.

11. The method of claim 8, wherein a controller is programmed to activate a shading device to cover the solar collector in order to prevent solar energy from entering the solar collector in response to an overheating warning signal.

12. The method of claim 8, wherein the solar collector directs the concentrated solar energy to the solar panel via at least one fiber optic cable.

13. The method of claim 8, wherein the solar collector collects solar energy from a surface area that is larger than a surface area of the solar panel.

14. The method of claim 8, wherein the solar collector is located on a canopy of the parking structure.

15. A vehicle configured to interact with a solar collector that includes a shading device, wherein the solar collector is configured to collect and concentrate solar energy and the shading device is configured to cover the solar collector when activated in order to prevent solar energy from entering the solar collector, comprising:

a solar panel rigidly affixed to the vehicle, configured to receive concentrated solar energy, and charge a battery; and

a controller programmed to,

in response to a change in a direction of focus of the concentrated solar energy, adjust the position of the vehicle such that the concentrated solar energy remains directed to the solar panel, and

in response to an overheating warning signal, activate the shading device.

16. The vehicle of claim 15, wherein the solar panel is mounted to a roof of the vehicle.

17. The vehicle of claim 15, wherein the solar panel has a smaller surface area than a surface area of the solar collector that is utilized to collect the solar energy.
