After which, in particular, a motor 26 of the at least one shifting element 24 disengages and drives the connector connecting the car to the charging connector capsule 18 out of its socket 20.

[0034] A spring cover or shutter 28 snaps or moves from the position shown in Fig. 1 when the connector 22 is still connected via a plug 30, to the position shown in Fig. 2 when the connector is disconnected. This closes of the contact area with any high voltage components or contacts included in the plug 30, thereby protecting the user or anyone who were to interact with the capsule 18 after injection.

[0035] After the spring cover or shutter 28 is closed, a pin mechanism 44 may be released via mechanical means such as a motor so that the capsule 18 may be released. The motor may receive a signal from the control element 32 for the emergency disconnect feature. The pin mechanism 44 secures the capsule 18 in the vehicle to prevent the capsule 18 from being removed from the vehicle during normal operation.

[0036] In particular, two motors 26 begin ejecting the capsule 18 from the vehicle in doing so the charging plug 12 with the capsule 18 is ejected from the vehicle and the customer is free to drive away without leaving the safety of the vehicle.

[0037] The control element 32 is provided for initiating the release of the connector plug 14 and for ejecting the capsule 18. The control element 32 in its intended position of use may be arranged on the vehicle’s inner roof, on a steering wheel column, in a driver footwell and / or a head unit softkey. In the inner roof, the position may be close to an SOS-button. In the steering wheel column, the position may be between the steering wheel and the instrument cluster. On the driver’s footwell, the position may be on the opposite side of the hook release. The position on the head unit softkey may be only available while charging.

[0038] As shown in Fig. 1, the capsule 18 may comprise capsule ejection pads 34 that serve as contact points or support pins of the at least one or, in particular, two shifting elements 24, as shown in Fig. 2, wherein the respective shifting element 24 comprises a lead screw 36 that is displaced by rotating the motors 26 to eject the capsule 18. The shifting element 24 may be supported by an internally threaded ejector 40 (shown in Fig. 3).

[0039] Fig. 3 shows that the internally threaded ejector 40 includes at least one arrestor 42 in a perspective side view and top view. In the top view, one can see the arrestor 42 to hold the shifting element 24 (as shown in Fig. 2), and the internally threaded ejector 40 straight throughout the range of motion which is provided by turning the motor 26.

[0040] Furthermore, Fig. 2 shows a handle 38 may be provided for removing the charging plug 14 (as shown in Fig. 4) of the capsule 18. The plug connection 22 or the plug 30 may comprise an internal thread 16 for the at least one shifting element 24 so that the plug connection 22 and the plug 30 could be easily removed from the capsule 18.
