Abstract

An auxiliary power pack for a vehicle includes an energy harvesting system for converting energy from an ambient environment into electrical power, a storage device in communication with the energy harvesting device for storing energy in response to the electrical power, and an output interface in communication with the storage device for supplying the stored energy to an electronic device. The power pack further includes a portable housing for the energy harvesting system, the storage device and the output interface. The housing is configured for removable mounting to a vehicle.

Claims

1. An automotive vehicle having a battery, comprising:

an exterior vehicle panel of the automotive vehicle defining a recess within a surface of the exterior vehicle panel; and

a portable power pack removably mounted within the recess, the power pack including;

a solar panel for converting solar energy into electrical power,

a storage device in communication with the solar panel for storing energy in response to the electrical power, and

an output interface in communication with the storage device for supplying the stored energy to an electronic device.

2. The vehicle of claim 1, further comprising:

a powered vehicle accessory that includes the electronic device, wherein the output interface at least partially forms a disconnectable electrical coupling between the storage device and the electronic device.

3. The vehicle of claim 1, wherein the electronic device is a consumer electronic device and the output interface is configured to at least partially form a disconnectable electrical coupling between the storage device and the consumer electronic device.

4. The vehicle of claim 1, wherein the portable power pack defines an exterior surface of the vehicle panel when housed in the recess, with the exterior surface being generally flush with the vehicle panel when the portable power pack is mounted in the recess.

5. The vehicle of claim 4, wherein the exterior surface of the portable power pack includes a generally planar work surface.

6. The vehicle of claim 1, further comprising:

a second energy storage device separate from the portable power pack; and

a disconnectable electrical coupling between the second energy storage device and the energy storage device included in the portable power pack.

7. The vehicle of claim 1, further comprising:

an energy harvesting device separate from the portable power pack; and

a disconnectable electrical coupling between the energy harvesting device and the energy storage device.

8. The vehicle of claim 1, wherein the portable power pack includes a locking mechanism for selectively locking the portable power pack within the recess of the vehicle panel.

9. The vehicle of claim 1, wherein the portable power pack further includes a device configured for converting vibration energy into electrical power.

10. The vehicle of claim 1, wherein the electronic device is located on the exterior vehicle panel and the portable power pack powers the electronic device when the portable power pack is mounted within the recess.

11. The vehicle of claim 1, wherein the electronic device is remote from the vehicle and the portable power pack powers the electronic device when the portable power pack is removed from the recess.

12. The vehicle of claim 1, wherein the electronic device is located within a vehicle accessory within the vehicle and the portable power pack powers the electronic device when the portable power pack is mounted within the recess.

13. A vehicle, comprising:

a tailgate of the vehicle configured for removable attachment from a remainder of the vehicle;

a powered vehicle accessory supported on or in the tailgate, the powered vehicle accessory including at least one electronic device;

a power pack removably mounted to the tailgate, the power pack including;

a solar panel for converting solar energy into electrical power, and

a storage device in communication with the solar panel for storing energy in response to the electrical power; and

a disconnectable electrical coupling between the storage device and the electrical device of the powered vehicle accessory on or in the tailgate.

14. The vehicle of claim 13, wherein the powered vehicle accessory includes one of a light, a backup camera or a powered lock supported on or in the tailgate.

15. The vehicle of claim 13, wherein the power pack further includes a device configured for converting vibration energy into electrical power.

16. A vehicle powered at least in part by a battery, comprising:

an exterior vehicle panel defining a recess within a surface of the exterior vehicle panel; and

a portable power pack removably mounted within the recess, the power pack including;

a solar panel for converting solar energy into electrical power,

a storage device in communication with the solar panel for storing energy in response to the electrical power, and

an output interface in communication with the storage device for supplying the stored energy to the battery of the vehicle when the portable power pack is mounted within the recess.

17. The vehicle of claim 16, wherein the portable power pack further includes a device configured for converting vibration energy into electrical power.
