Abstract

In various embodiments, a charging station enclosure is provided having a casing for enclosing circuitry therein, the casing comprising a side wall surrounding the circuitry, wherein at least a portion of the side wall comprises a double wall with a space therebetween.

Claims

1. A charging station enclosure comprising a casing for enclosing circuitry therein, the casing comprising a side wall surrounding the circuitry, wherein at least a portion of the side wall comprises a double wall with a space therebetween.

2. The charging station enclosure of claim 1, wherein the casing further comprises wall supports in the space between the double wall.

3. The charging station enclosure of claim 2, wherein the wall supports comprise drainage features.

4. The charging station enclosure of claim 3, wherein the casing further comprises drainage openings.

5. The charging station enclosure of claim 3, wherein the drainage features comprise a drainage port.

6. The charging station enclosure of claim 3, wherein the enclosure comprises a front plate fastened to the casing, and wherein the drainage features comprise a space between the wall supports and the front plate.

7. The charging station enclosure of claim 6, wherein the casing further comprises drainage openings.

8. The charging station enclosure of claim 7, wherein the drainage features comprise a drainage port.

9. The charging station enclosure of claim 8, wherein an outer wall of the double wall comprises the drainage openings.

10. The charging station enclosure of claim 2, wherein at least some of the wall supports comprise fastener receivers.

11. The charging station enclosure of claim 10, wherein the double wall comprises an inner wall and an outer wall, and wherein the enclosure comprises a front plate fastened to the casing, and further comprises a gasket creating a seal between the front plate and the inner wall.

12. The charging station enclosure of claim 10, wherein M the wall supports with fastener receivers comprise drainage ports.

13. The charging station enclosure of claim 1, further comprising thermal insulation in the space between the double walls.

14. A charging station enclosure comprising a casing for enclosing circuitry therein, the casing comprising:

a) a side wall surrounding the circuitry, wherein at least a portion of the side wall comprises an inner wall and an adjacent outer wall; and

b) a front plate fastened to the casing.

15. The charging station enclosure of claim 15, further comprises a gasket creating a seal between the front plate and the inner wall.

16. The charging station enclosure of claim 15, wherein the front plate is fastened to the casing with a water tight seal between the front plate and the inner wall such that water penetrating past an interface between the outer wall and the face plate is directed away from passing beyond the inner wall.

17. The charging station enclosure of claim 16, further comprising at least one drainage opening so as to allow accumulated water between the inner wall and the outer wall to drain therefrom.

18. The charging station enclosure of claim 17, wherein the casing further comprises wall supports in a space between the inner wall and the outer wall, and wherein the wall supports comprise drainage features.

19. The charging station enclosure of claim 15 further comprising fastener receivers located between the inner wall and the outer wall.

20. The charging station enclosure of claim 19, wherein the front plate is fastened to the casing via fasteners such that the fasteners are received by the fasteners receivers.

21. The charging station enclosure of claim 15, further comprising thermal insulation between the inner wall and the outer wall.

22. A charging station enclosure comprising a casing for enclosing circuitry therein, the casing comprising:

a) a side wall surrounding the circuitry;

b) a rear mounting surface; and

c) a front facing user interface panel having an angle with respect to the rear mounting surface so as to facilitate viewing by a user when viewing from a positioned adjacent to and above the charging station enclosure.

23. The charging station enclosure of claim 22, wherein the front facing panel has an angle of approximately ten degrees toward the rear mounting surface.

24. The charging station enclosure of claim 23, wherein the side wall comprises a generally truncated conical configuration.

25. The charging station enclosure of claim 22, wherein the side wall comprises a generally truncated conical configuration.

27. The charging station enclosure of claim 26, wherein the connector receptacle is recessed from the front facing user interface panel.

28. The charging station enclosure of claim 27 further comprising a plurality of stiffening plates extending from a rear surface of the casing.

29. A charging station enclosure comprising:

a) a surrounding side wall;

b) a front plate secured to the side wall; and

c) a rear portion comprising;

(1) an opening for receiving a electric utility wiring; and

(2) a plurality of exclusion spacers positioned adjacent to the opening.

30. The charging station enclosure of claim 29, wherein the plurality of exclusion spacers extend from the rear portion into and interior of the enclosure.

31. The charging station enclosure of claim 29 further comprising a power transfer cable opening in a downward facing portion of the side wall.

32. The charging station enclosure of claim 31 further comprising a connector receptacle recessed from the front plate for receiving and retaining an energy transfer connector of a power transfer cable.

33. The charging station enclosure of claim 29 further comprising a plurality of stiffening plates extending from the rear portion.

34. The charging station enclosure of claim 33, wherein the plurality of stiffening plates further extend from a bottom portion of the enclosure.
