Abstract

A latch-locking device for an electric vehicle charging connector having a movable latching element for engaging a matching latching element on a charging station, or on an electric vehicle. The latch-locking device includes a movable latch-locking element mounted adjacent the matching latching element on the charging station or an electric vehicle for movement, in a direction transverse to the direction of movement of the movable latching element, between a retracted position spaced away from the matching latching element and an advanced position where the latch-locking element overlaps at least a portion of the movable latching element when the movable latching element is engaged with the matching latching element. An actuator is coupled to the latch-locking element for moving the locking element between the retracted and advanced positions.

Claims

1. A locking device for an electric vehicle charging connector having a movable latching element for engaging a matching latching element on a charging station or an electric vehicle, said locking device comprising

a movable locking element mounted adjacent said matching latching element for movement, in a direction transverse to a direction of movement of said movable latching element, between a retracted position spaced away from said matching latching element and an advanced position where said locking element overlaps at least a portion of said movable latching element when said movable latching element is engaged with said matching latching element, and

an actuator coupled to said locking element for moving said locking element between said retracted and advanced positions.

2. The locking device of claim 1 which includes a housing supporting said movable locking element and said actuator, said housing being adapted for mounting adjacent said matching latching element on a charging station or an electric vehicle.

3. The locking device of claim 2 in which said housing is adapted to be retrofitted on said charging station or an electric vehicle.

4. The locking device of claim 1 which includes a second locking element for locking said movable locking element in said advanced position.

5. The locking device of claim 4 in which said second locking element is key operated.

6. The locking device of claim 1 which includes a proximity sensor for sensing the presence of said movable latching element latched to said matching latching element.

7. The locking device of claim 1 in which said actuator is a linear electrical actuator.

8. The locking device of claim 1 in which said actuator is manually operated.

9. The locking device of claim 1 wherein said movable latching element is a spring-loaded detent fitting over the matching latching element upon full engagement therewith.

10. A docking station for stowing an electric vehicle connector, said connector having a first end connected to a power cable and a second end that includes multiple first electrical terminals adapted to engage mating electrical terminals in an electrical receptacle in said electric vehicle, said second end also including a protruding latching element adapted to engage a cooperating latching element in said electrical receptacle, said docking station comprising

a stowing receptacle adapted to receive said second end of said connector when said connector is not in use, and

a locking device having a movable locking element mounted adjacent said cooperating latching element for movement, in a direction transverse to the direction of movement of said movable latching element, between a retracted position spaced away from said cooperating latching element and an advanced position where said locking element overlaps at least a portion of said protruding latching element when said protruding latching element is engaged with said cooperating latching element, and an actuator coupled to said locking element for moving said locking element between said retracted and advanced positions.

11. The docking station of claim 10 which includes a housing supporting said movable locking element and said actuator, said housing being adapted for mounting adjacent said matching latching element on a charging station or an electric vehicle.

12. The locking device of claim 11 in which said housing is adapted to be retrofitted on said charging station or an electric vehicle.

13. The locking device of claim 10 which includes a second locking element for locking said movable locking element in said advanced position.

14. The locking device of claim 13 in which said second locking element is key operated.

15. The locking device of claim 10 which includes a proximity sensor for sensing the presence of said movable latching element latched to said matching latching element.

16. The locking device of claim 10 in which said actuator is a linear electrical actuator.

17. The locking device of claim 10 in which said actuator is manually operated.

18. The locking device of claim 10 in which said movable latching element is a spring-loaded detent fitting over the matching latching element upon full engagement therewith.
