Abstract

A vehicle charging system comprises at least one controller and at least one arm, each arm having a first end coupled to an actuator and a second end comprising a charging interface. The actuator is configured to articulate the arm into a charging position. The charging interface comprises at least one charging contact coupled to a power source and configured to engage and deliver power to a vehicle charging interface to charge at least one battery of a vehicle. The charging system can include a plurality of arms, each configured to charge a different vehicle. A method of charging one or more vehicles using the charging system is also provided.

First claim

What is claimed is:

1 . A charging head apparatus, comprising:
a charging interface, including:
at least one magnet; and
at least one compressible charger contact that is configured to deliver a current when compressed; and
at least one controller configured to enable the at least one magnet, wherein the at least one charger contact protrudes from the charging interface beyond the at least one magnet, wherein the at least one magnet is located within a recess of the charging interface, the recess having first and second side surfaces defining an opening, and wherein at least one side surface of the at least one magnet is spaced apart from one of the first and second side surfaces of the recess forming a gap between the at least one side surface of the at least one magnet and the one of the first and second side surfaces of the recess.

2 . The apparatus of claim 1 , wherein the at least one magnet includes one or more magnets located within the recess of the charging interface.

3 . The apparatus of claim 1 , wherein the at least one magnet includes at least one centrally located magnet.

4 . The apparatus of claim 3 , wherein the at least one centrally located magnet comprises a plurality of centrally located magnets.

5 . The apparatus of claim 4 , wherein the plurality of centrally located magnets includes at least one centrally located magnet located within a recess of the charging interface.

6 . The apparatus of claim 5 , wherein the at least one centrally located magnet located within the recess of the charging interface comprises a plurality of centrally located magnets within the recess of the charging interface.

7 . The apparatus of claim 1 , wherein the at least one charger contact is a plurality of charger contacts.

8 . The apparatus of claim 7 , wherein the plurality of charger contacts includes one or more charger contacts on each side of the at least one magnet.

9 . The apparatus of claim 1 , wherein the at least one charger contact includes at least one charger contact supported by a spring to make the charger contact compressible.

10 . The apparatus of claim 1 , wherein the at least one charger contact includes a charger contact coupled to a collector base.

11 . The apparatus of claim 10 , wherein the charger contact is configured to that once the charger contact is compressed a charging connection is established between the charger contact and the collector base,
wherein the connection enables the current to be delivered through the charger contact via the collector base.

12 . The apparatus of claim 11 , wherein the at least one charger contact includes a plurality of charger contacts each coupled to a respective collector base.

13 . The apparatus of claim 1 , further comprising:
at least one arm movably coupled to the charging interface, and at least one actuator operatively coupled to the at least one arm and the at least one controller, wherein:
the at least one controller is configured to drive the at least one actuator to articulate the at least one arm into a charging position in response to a charge cycle indication, and
the at least one controller is configured to drive the at least one actuator to articulate the at least one arm into a non-charging position in response to a charge cycle complete indication.

14 . A charging head apparatus, comprising:
a charging interface, including:
at least one centrally located magnet; and
a plurality of compressible charger contacts configured to deliver a current when compressed; and
at least one controller configured to enable the at least one centrally located magnet, wherein each of the plurality of charger contacts protrudes from the charging interface beyond the at least one magnet, wherein the at least one centrally located magnet is located within a recess of the charging interface, the recess having first and second side surfaces defining an opening, and wherein at least one side surface of the at least one centrally located magnet is spaced apart from one of the first and second side surfaces of the recess forming a gap between the at least one side surface of the at least one magnet and the one of the first and second side surfaces of the recess.

15 . The apparatus of claim 14 , wherein the at least one centrally located magnet includes a plurality of centrally located magnets.

16 . The apparatus of claim 15 , wherein the plurality of centrally located magnets includes at least one centrally located magnet located within the recess of the charging interface.

17 . The apparatus of claim 14 , wherein the plurality of compressible charger contacts includes one or more compressible charger contacts on each side of the at least one centrally located magnet.

18 . The apparatus of claim 14 , wherein each of the plurality of compressible charger contacts is supported by a respective spring.

19 . The apparatus of claim 14 , wherein each of the plurality of compressible charger contacts is coupled to a respective collector base.

20 . The apparatus of claim 19 , wherein each compressible charger contact is configured so that a charging connection is established between the compressible charger contact and the respective collector base when the compressible charger contact is compressed, wherein the charging connection enables the current to be delivered through the compressible charger contact via the respective collector base.

21 . The apparatus of claim 20 , wherein each collector base includes a connection to a charging lead configured to carry the current to the collector base.
