Abstract

A power conduit for charging a power storage device of a vehicle includes an output terminal and locking mechanism operatively disposable in one of an engaged and a disengaged position. The locking mechanism locks the output terminal to the vehicle when the locking mechanism is in the engaged position and unlocks the output terminal when in the disengaged position. The power conduit includes a controller including a memory device configured to store a plurality of computer-executable instructions and a processor coupled to the memory device. The instructions configure the processor to receive an identifier associated with one of the vehicle and a user of the vehicle, and generate and transmit an unlocking signal to cause the locking mechanism to be in the disengaged position upon one of a determination that the identifier was received and a determination that a predetermined charge state of the power storage device has been reached.

Claims

1. A power conduit for charging a power storage device of a vehicle, said power conduit comprising:

an output terminal;

a locking mechanism operatively disposable in one of an engaged position and a disengaged position, wherein said locking mechanism is configured to lock said output terminal to the vehicle when said locking mechanism is disposed in the engaged position and configured to unlock said output terminal from the vehicle when said locking mechanism is in the disengaged position; and

a controller operatively coupled to said locking mechanism, said controller comprising;

a memory device configured to store a plurality of computer-executable instructions; and

a processor coupled to said memory device, wherein, when executed by said processor, the computer-executable instructions configure said processor to;

receive an identifier associated with one of the vehicle and a user of the vehicle; and

generate and transmit an unlocking signal to cause said locking mechanism to be in the disengaged position upon one of a determination that the identifier was received and a determination that a predetermined charge state of the power storage device has been reached.

2. A power conduit in accordance with claim 1, further comprising a communication device configured to receive the identifier and to transmit the identifier to said processor.

3. A power conduit in accordance with claim 2, wherein said power conduit is configured to be coupled to a charging device positioned remotely from the vehicle, said communication device is configured to receive the identifier from the charging device.

4. A power conduit in accordance with claim 1, further comprising a user interface configured to receive the identifier and to transmit the identifier to said processor.

5. A power conduit in accordance with claim 1, further comprising an actuator configured to cause said locking mechanism to be in the engaged position.

6. A power conduit in accordance with claim 1, wherein said processor is configured to:

receive the identifier a first time;

generate and transmit a locking signal to cause said locking mechanism to be in the engaged position upon a determination that the identifier was received the first time;

receive the identifier a second time; and

generate and transmit the unlocking signal to cause said locking mechanism to be in the disengaged position upon a determination that the identifier was received the second time.

7. A power conduit in accordance with claim 1, wherein said output terminal is configured to be electrically coupled to the power storage device and said controller is positioned proximate said output terminal

8. A charging device for use in charging a power storage device of a vehicle through a power conduit that includes an output terminal and a locking mechanism operatively disposable in one of an engaged position and a disengaged position, wherein the locking mechanism is configured to lock the output terminal of the power conduit to the vehicle when the locking mechanism is in the engaged position and configured to unlock the output terminal from the vehicle when the locking mechanism is in the disengaged position, said charging device comprising:

a memory device configured to store a plurality of computer-executable instructions; and

a processor coupled to said memory device, wherein, when executed by said processor, the computer-executable instructions configure said processor to;

receive an identifier associated with one of the vehicle and a user of the vehicle; and

transmit an unlocking signal to the power conduit to cause the locking mechanism to be in the disengaged position upon one of a determination that the identifier was received and a determination that a predetermined charge state of the power storage device has been reached.

9. A charging device in accordance with claim 8, further comprising a communication device configured to receive the identifier and to transmit the identifier to said processor.

10. A charging device in accordance with claim 8, further comprising a user interface configured to receive the identifier and to transmit the identifier to said processor.

11. A charging device in accordance with claim 8, wherein said processor is configured to:

receive the identifier a first time;

transmit a locking signal to the power conduit to cause the locking mechanism to be in the engaged position upon a determination that the identifier was received the first time;

receive the identifier a second time; and

transmit the unlocking signal to the power conduit to cause the locking mechanism to be in the disengaged position upon a determination that the identifier was received the second time.

12. A charging device in accordance with claim 11, wherein said processor is further configured to initiate a charging operation of the power storage device after the locking signal has been transmitted to the power conduit.

13. A charging device in accordance with claim 12, wherein said processor is further configured to:

terminate the charging operation; and

14. A method of charging a power storage device of an electric vehicle using a charging device and a power conduit configured to be coupled to the charging device and the electric vehicle, wherein the power conduit includes an output terminal and a locking mechanism, said method comprising:

engaging the locking mechanism of the power conduit to lock the output terminal of the power conduit to the electric vehicle;

initiating a charging operation to charge the power storage device of the electric vehicle using the charging device;

receiving, by a processor, an identifier associated with one of the electric vehicle and a user of the electric vehicle; and

generating, by the processor, an unlocking signal for disengaging the locking mechanism to unlock the output terminal from the electric vehicle upon one of a determination that the identifier was received and a determination that a predetermined charge state of the power storage device has been reached.

15. A method in accordance with claim 14, wherein a communication device is included within at least one of the charging device and the power conduit, said method further comprising receiving the identifier by the communication device.
