Abstract

Methods and devices for connecting a current source to a target storage device via a transmission cable extendable and/or retractable via a conduit that may be repositioned.

Claims (35)

1. A battery charging device comprising:

a conduit segment configured to receive an extending transmission cable, wherein the conduit segment is further configured to slidably conduct the transmission cable;

the transmission cable connectable to a current source; and

a transmission cable drive mechanism configured to extend the transmission cable into the conduit segment.

2. The battery charging device of claim 1 wherein the transmission cable is disposed about at least one drive wheel aligned to extend the transmission cable in a direction away from a transmission cable housing and into the conduit segment.

3. The battery charging device of claim 1 wherein the transmission cable drive mechanism comprises a tow wire and drive pulley.

4. The battery charging device of claim 1 wherein the transmission cable drive mechanism is further configured to retract the transmission cable from the conduit segment.

5. The battery charging device of claim 1 further comprising a conduit assembly comprising the conduit segment and a handle-connector assembly comprising a transmission cable connector and a target port connector.

6. The battery charging device of claim 5 wherein the transmission cable drive mechanism comprises a pressure differential generator effecting a pressure differential, the pressure differential having a volume of lower pressure effected proximate to the handle-connector assembly.

7. The battery charging device of claim 1 wherein the transmission cable is air-cooled within the conduit segment.

8. The battery charging device of claim 1 further comprising a housing comprising:

the transmission cable; and

the transmission cable drive mechanism configured to extend the transmission cable into the conduit segment.

9. The battery charging device of claim 1 wherein the transmission cable is comprised of at least two conductive cables.

10. The battery charging device of claim 1 wherein the transmission cable is comprised of four conductive cables.

11. The battery charging device of claim 1 wherein a coating having a low coefficient of sliding friction is interposed between the transmission cable and the conduit segment.

12. The battery charging device of claim 1 wherein the transmission cable drive mechanism comprises a first wheel opposing a second wheel, wherein at least one of the first wheel and the second wheel is a drive wheel and wherein at least one of the first wheel and the second wheel is configured to retractably engage the transmission cable.

13. The battery charging device of claim 12 wherein at least one of the first wheel and the second wheel is configured to retractably engage the transmission cable via a powered solenoid.

14. A method of charging a target storage device comprising:

engaging a target storage device electrical receptacle with the target port connector of a conduit assembly comprising a conduit segment, wherein the conduit segment is further configured to slidably conduct a transmission cable;

extending the transmission cable, within the conduit segment and away from a conduit assembly support structure, by a transmission cable drive mechanism, to engage the target port connector via the conduit segment; and

initiating current flow to the target storage device from a current source via the transmission cable.

15. The method of charging a target storage device of claim 14 wherein the transmission cable is disposed about at least one drive wheel aligned to extend the transmission cable in a direction away from the housing and into the conduit segment.

16. The method of charging a target storage device of claim 14 wherein the transmission cable drive mechanism comprises a tow wire and drive pulley.

17. The method of charging a target storage device of claim 14 further comprising:

stopping current flow to the target storage device from the current source via the transmission cable and

retracting the transmission cable from the conduit segment.

18. The method of charging a target storage device of claim 14 further comprising air cooling the transmission cable within the conduit segment.

19. The method of charging a target storage device of claim 14 wherein a housing comprises the conduit assembly support structure.

20. The method of charging a target storage device of claim 14 wherein a coating having a low coefficient of sliding friction is interposed between the transmission cable and the conduit segment.

21. A battery charging device comprising:

a conduit segment configured to receive a transmission cable, wherein the conduit segment is further configured to slidably conduct the transmission cable;

wherein the transmission cable is connectable to a current source; and wherein the transmission cable is configured to extend into the conduit segment.

22. The battery charging device of claim 21 wherein the transmission cable is air-cooled within a volume between the transmission cable and the conduit segment.

23. The battery charging device of claim 21 wherein a coating having a low coefficient of sliding friction is interposed between the transmission cable and the conduit segment.
