Abstract

A power distribution system includes a charging station, a plurality of power socket assemblies, and at least one power line. The charging station includes a charging station control module. The plurality of power socket assemblies are operable to supply power to a vehicle. The at least one power line electrically connects the charging station to each of the plurality of power socket assemblies. The charging station is configured to supply power to any one of the plurality of power socket assemblies through the at least one power line.

First claim

What is claimed is:

1. A power distribution system comprising:
a charging station including a charging station control module;
a plurality of power socket assemblies operable to supply power to a vehicle, wherein each of the power socket assemblies includes a power socket;
at least one power line electrically connecting the charging station to each of the plurality of power socket assemblies, wherein the charging station is configured to supply power to any one of the plurality of power socket assemblies through the at least one power line; and
a mobile charger including a power plug that is configured to electrically connect the vehicle to the power socket of any one of the plurality of power socket assemblies, wherein the mobile charger is operable to move to align the power plug with the power socket.

2. The power distribution system of claim 1 wherein the at least one power line includes a single power line that electrically connects the charging station to all of the plurality of power socket assemblies.

3. The power distribution system of claim 1 wherein the at least one power line includes a first power line and a second power line, the first power line electrically connecting the charging station to a first subset of the plurality of power socket assemblies, the second power line electrically connecting the charging station to a second subset of the plurality of power socket assemblies.

4. The power distribution system of claim 1 wherein the at least one power line includes a main power line and a plurality of branch power lines, the main power line electrically connecting the charging station to the plurality of branch power lines, each of the plurality of branch power lines electrically connecting the main power line to at least one of the plurality of power socket assemblies.

5. The power distribution system of claim 1 wherein each of the plurality of power socket assemblies includes a switch operable to regulate current flow from the at least one power line to the power socket.

6. The power distribution system of claim 5 wherein each of the plurality of power socket assemblies further includes a power socket control module configured to open and close the switch in response to a wireless control signal.

7. The power distribution system of claim 5 wherein:
each of the plurality of power socket assemblies further includes a socket cover that allows access to the respective socket when the socket cover is open and prevents access to the respective socket when the socket cover is closed; and
each of the plurality of power socket assemblies further includes a power socket control module configured to open and close the socket cover in response to a wireless control signal.

8. The power distribution system of claim 1 wherein:
the mobile charger further includes a base, a plurality of wheels attached to the base, and an electrical connector into which the power plug integrated, and
the electrical connector is configured to extend and retract relative to the base to respectively insert the power plug into the power socket of any one of the plurality of power socket assemblies and withdraw the power plug from the power socket.

9. The power distribution system of claim 1 wherein:
the mobile charger further includes a mobile charger control module and a contact sensor integrated into the power plug; and
the mobile charger control module is configured to determine whether the power plug is inserted into the power socket of any one of the plurality of power socket assemblies based on an input from the contact sensor.

10. The power distribution system of claim 9 wherein:
the mobile charger control module is configured to generate a wireless ON code signal when the power plug is inserted into the power socket of any one of the plurality of power socket assemblies; and
in response to the wireless ON code signal, the charging station control module is configured to close a switch in the respective one of the plurality of power socket assemblies to supply power to the power socket of the respective one of the plurality of power socket assemblies.

11. The power distribution system of claim 9 wherein:
the mobile charger control module is configured to generate a wireless OFF code signal when the power plug is withdrawn from the power socket of any one of the plurality of power socket assemblies; and
in response to the wireless OFF code signal, the charging station control module is configured to open a switch in the respective one of the plurality of power socket assemblies to interrupt power supply to the power socket of the respective one of the plurality of power socket assemblies.

12. The power distribution system of claim 1 wherein:
the mobile charger further includes a mobile charger control module and an image sensor integrated into the power plug; and
the mobile charger control module is configured to determine whether the power plug is aligned with the power socket of any one of the plurality of power socket assemblies based on an input from the image sensor.

13. The power distribution system of claim 1 wherein:
the mobile charger further includes a mobile charger control module, an image sensor integrated into the power plug, and an air nozzle; and
each of the plurality of power socket assemblies further includes a socket cover operable to open and close to respectively allow and prevent access to the respective socket; and
the mobile charger control module is configured to:
determine whether a substance is disposed on a top surface of the socket cover of any one of the plurality of power sockets assemblies based on an input from the image sensor; and
control the air nozzle to spray air toward the socket cover when the substance is disposed on the top surface of the socket cover.

14. The power distribution system of claim 13 wherein:
the mobile charger further includes a base, a plurality of wheels attached to the base, and a protection shield coupled to the base; and
the protection shield is configured to extend and retract relative to the base to respectively create a seal around the socket cover of any one of the plurality of power socket assemblies and break the seal.
