Abstract

An assembly includes a movable door assembly and a heating element. The movable door assembly is configured to be disposed on an exterior of a vehicle. The heating element is coupled to the movable door assembly, and is configured to receive energy from a battery disposed on the vehicle and to heat at least a portion of the movable door assembly.

First claim

We claim:

1. An assembly comprising:
a door assembly configured to be disposed on an exterior surface of a vehicle, wherein the door assembly is hingedly movable with respect to the exterior of the vehicle; and
a heating element coupled to the door assembly, the heating element configured to receive energy from at least one of a battery disposed on the vehicle or a charging cable, and to heat at least a portion of the door assembly.

2. The assembly of claim 1 , wherein the heating element comprises a positive thermal coefficient (PTC) material.

3. The assembly of claim 1 , further comprising a controller and a temperature sensor, the controller configured to provide heat to the door assembly via the heating element responsive to an input from the temperature sensor.

4. The assembly of claim 1 , further comprising a controller and a charging sensor, the controller configured to provide heat to the door assembly via the heating element responsive to an input from the charging sensor.

5. A heated energy port assembly comprising:
a housing configured to be disposed along an exterior of a vehicle, the housing defining a cavity configured to accept an external power source for insertion into a port disposed within the cavity;
a door assembly comprising a hingedly movable door coupled to the housing;
a seal interposed between the hingedly movable door and the housing; and
a heating element coupled to at least one of the housing, the hingedly movable door, or the seal, the heating element configured to heat at least a portion of the at least one of the housing, the hingedly movable door, or the seal.

6. The heated energy port assembly of claim 5 , wherein the heating element comprises a positive thermal coefficient (PTC) material.

7. The heated energy port assembly of claim 5 , further comprising a controller and a temperature sensor, the controller configured to provide heat to the at least one of the housing, the movable door, or the seal via the heating element responsive to an input from the temperature sensor.

8. The heated energy port assembly of claim 5 , further comprising a controller and a charging sensor, the controller configured to provide heat to the at least one of the housing, the movable door, or the seal via the heating element responsive to an input from the charging sensor.

9. The heated energy port assembly of claim 5 , wherein at least one of the housing or the movable door comprises an integrated PTC element.

10. The heated energy port assembly of claim 5 , wherein the housing has a housing front face and the movable door has a door rear face, the housing front face and the door rear face opposing each other and oriented toward each other, wherein the heating element is disposed along at least one of the housing front face or the door rear face.

11. The heated energy port assembly of claim 5 , wherein the housing has a housing rear face and the movable door has a door front face, the housing rear face and the door front face opposing each other and oriented away from each other, wherein the heating element is disposed along at least one of the housing rear face or the door front face.

12. The heated energy port assembly of claim 5 , wherein the heating element includes a resistive wire element integrated into at least one of the housing or movable door.

13. The heated energy port assembly of claim 5 , wherein the heating element is configured to receive energy from a battery disposed on the vehicle.

14. The heated energy port assembly of claim 5 , wherein the heating element is configured to receive energy via a charging cable.

15. A method of providing a heated energy port assembly, the method comprising:
providing a housing configured to be disposed along an exterior of a vehicle, the housing defining a cavity configured to accept an external power source for insertion into a port disposed within the cavity;
coupling a door assembly comprising a hingedly movable door to the housing;
disposing a seal between the movable door and the housing; and
providing a heating element coupled to at least one of the housing, the hingedly movable door, or the seal, the heating element configured to receive energy from a battery disposed in the vehicle and to heat at least a portion of the at least one of the housing, the hingedly movable door, or the seal.

16. The method of claim 15 , wherein the heating element comprises a positive thermal coefficient (PTC) material.

17. The method of claim 15 , further comprising integrating a PTC element into at least one of the housing or the movable door.

18. The method of claim 15 , wherein the housing has a housing front face and the hingedly movable door has a door rear face, the housing front face and the door rear face opposing each other and oriented toward each other, wherein the heating element is disposed along at least one of the housing front face or the door rear face.

19. The method of claim 15 , wherein the housing has a housing rear face and the hingedly movable door has a door front face, the housing rear face and the door front face opposing each other and oriented away from each other, wherein the heating element is disposed along at least one of the housing rear face or the door front face.

20. The method of claim 15 , wherein the heating element includes a resistive wire element integrated into at least one of the housing or the hingedly movable door.
