Abstract

A charge port illumination system for a vehicle includes a charge port configured for electrically connecting to a charging source to charge a power source of the vehicle. A pocket assembly is disposed at or proximate to the charge port and includes a base and a bezel at an outer region of the base. At least a portion of the bezel is exposed and viewable when the charge port is accessed to charge the power source. At least one illumination source is disposed at or behind the bezel. The illumination source, responsive to an activating event associated with an electric charging event, is activated to provide backlighting of the bezel. The activated illumination source is automatically deactivated responsive to a deactivating event.

wherein the activated said at least one illumination source is automatically deactivated responsive to at least one of (a) a period of time elapsing after activation of said at least one illumination source, (b) plugging in a charging source at said charge port and (c) closing a cover panel at said pocket assembly.

2. The charge port illumination system of claim 1, wherein said bezel comprises an at least partially translucent polymeric material and is formed via an injection molding process.

3. The charge port illumination system of claim 2, wherein said bezel and said base comprise an at least partially translucent colored polymeric material.

4. The charge port illumination system of claim 1, wherein said bezel and said base are unitarily formed.

5. The charge port illumination system of claim 4, wherein said bezel and said base are unitarily formed via an injection molding process.

6. The charge port illumination system of claim 1, wherein said bezel flares outwardly at said outer region of said base and comprises a surface that is exposed and viewable when said charge port is accessed to charge the power source.

7. The charge port illumination system of claim 1, wherein said bezel comprises an at least partially translucent colored polymeric material and wherein illumination emitted by said at least one illumination source passes through said at least partially translucent colored polymeric material.

8. The charge port illumination system of claim 1, wherein said pocket assembly comprises circuitry, and wherein said circuitry comprises circuit elements used in activating said at least one illumination source to provide backlighting of said bezel.

9. The charge port illumination system of claim 8, wherein said circuit elements are used in deactivating the activated said at least one illumination source.

10. The charge port illumination system of claim 1, wherein a circuit board is disposed at said housing and wherein said circuit board has said at least one illumination source and associated circuitry disposed thereat.

11. The charge port illumination system of claim 1, wherein said circuitry comprises dimming control, and wherein said at least one illumination source, when being activated, is progressively adjusted from a lower illumination state towards a higher illumination state, and wherein said at least one illumination source, when being deactivated, is progressively adjusted from the higher illumination state towards the lower illumination state.

12. The charge port illumination system of claim 11, wherein at least one of (i) an intensity of illumination emanating from said at least one illumination source is varied to indicate the state of charge of the power source of the electric vehicle and (ii) said at least one illumination source is flashed to indicate the state of charge of the power source of the electric vehicle.

13. The charge port illumination system of claim 1, wherein illumination from said at least one illumination source is transmitted along and within said base to illuminate an inner end of said base opposite said bezel.

14. The charge port illumination system of claim 1, wherein said at least one illumination source comprises light piping.
