Abstract

Provided is an automated plug-in station for charging electric powered vehicles. The station includes a plug apparatus with a plug head that connects to an adapter on the electric powered vehicle and configured to pass electric charge to the battery of the electric powered vehicle. The plug apparatus extends automatically from a basin once proper alignment is established by a positioning system. Prior to charging, the plug apparatus is enclosed within the basin by a cover door which opens by an actuator when a vehicle enters the station; and when charging is complete, the plug automatically disconnects from the vehicle and withdraws back into the basin. The plug-in station also provides for receiving and processing payments at a payment system in the station.

Claims

1. An automated charging station for electric powered vehicles, the automated charging station comprising:

a plug apparatus having a plug head configured for transfer of electricity,

a vehicle adapter for operative connection between said plug head and battery of the vehicle, and

a structure to accommodate the plug apparatus and the vehicle for charging.

2. The charging station as defined in claim 1:

wherein the structure comprises at least one side barrier, vehicle alignment means, and sensor means adapted to be triggered by approach and/or position of the vehicle.

3. The charging station as defined in claim 2:

wherein the at least one side barrier includes an electronic payment means.

4. The charging station as defined in claim 1:

wherein the structure includes a roof covering.

5. The charging station as defined in claim 4:

wherein the roof covering includes a panel to generate solar power.

6. The charging station as defined in claim 1:

wherein the plug apparatus is contained in a basin below the vehicle.

7. The charging station as defined in claim 6:

wherein the basin includes a door cover.

8. The charging station as defined in claim 7:

wherein the door cover is adapted to be opened and closed by door means, the door means being powered by an external power source.

9. The charging station as defined in claim 1:

wherein the plug apparatus includes a shaft supporting an electric plug, the shaft being positioned within a supporting base below said vehicle before charging and being moveable to provide operative connection between the plug and the vehicle adapter.

10. The charging system as defined in claim 9:

wherein the shaft is vertically moveable by apparatus means, the apparatus means being powered by an external power source.

11. The charging system as defined in claim 9:

wherein an external power source provides power to be supplied through the plug to the vehicle.

12. The charging station as defined in claim 1:

further comprising a positioning system for locating the vehicle adapter and controlling the movement of the plug apparatus so that the plug is substantially aligned with the vehicle adapter.

13. The charging system as defined in claim 12:

wherein the positioning system comprises moveable support beams positioned generally perpendicularly, moveable by spring-loaded wheels between the support beams and the basin wall, and a movement-facilitating mechanism located on the underside of the plug apparatus.

14. The charging system as defined in claim 13:

wherein the positioning system further comprises a light reflector located beside the vehicle adapter and a light source at a location relative to said plug whereby proper alignment of the plug and the adapter is achieved when reflection occurs.

15. An automated electric powered vehicle charging station comprising:

guide means for guiding the vehicle to a predetermined location, the predetermined location adapted for charging the vehicle,

a movable plug apparatus having a plug head configured for transfer of electricity,

a basin for housing the movable plug apparatus while not in use,

positioning means for positioning the plug head for mating with a vehicle adapter, and

a structure to accommodate the plug apparatus and the vehicle for charging.

16. The charging system as defined in claim 15:

further comprising a structure to accommodate the movable plug apparatus and the vehicle for charging.

17. The charging station as defined in claim 16:

wherein the structure includes an electronic payment means.

18. A method for charging an electric powered vehicle, the method comprising:

sensing a vehicle in a predetermined location, the location adapted for charging at least one power cell of the vehicle,

opening a door to allow a plug to extend to the vehicle,

extending the plug to an adapter on the vehicle, the adapter electrically coupled to the at least one power cell, and

charging the at least one power cell for a predetermined time.

19. A method as defined in claim 18:

further including retracting the plug and closing the door.

20. A method as defined in claim 18:

further including accepting payment via payment means prior to extending the plug.
