## Abstract

The invention is characterised in that the device comprises a first (120), a second (130) and a third (110) elongated element; a first moving unit (140), pivotally connected to a first end of the first elongated element; a second moving unit (150), pivotally connected to a first end of the second elongated element; a cable connecting unit (160), pivotally connected to a second end of the first elongated element and to a second end of the second elongated element; and a control unit (170), in that the third elongated element is arranged to be fixedly mounted at a parking space, in that both moving units are arranged to be controlled by the control unit to be displaced in either direction along the third elongated element, in that such displacement causes the cable connecting unit to be displaced in relation to the third elongated element, and in that the cable connecting unit is arranged to connect the cable to the vehicle by pressing a connecting means (162) against a corresponding connector of the vehicle.

## Claims

### Claim 1

Device for automatically connecting a cable to a parked vehicle, comprising:
a first, a second and a third elongated element;
a first moving unit, pivotally connected to a first end of the first elongated element;
a second moving unit, pivotally connected to a first end of the second elongated element;
a cable connecting unit, pivotally connected to a second end of the first elongated element and to a second end of the second elongated element; and
a control unit,
wherein the third elongated element is arranged to be fixedly mounted at a parking space,
wherein in that both moving units are arranged to be controlled by the control unit to be displaced in either direction along the third elongated element,
wherein such displacement causes the cable connecting unit to be displaced in relation to the third elongated element, and
wherein the cable connecting unit is arranged to connect the cable to the vehicle by pressing a connecting means against a corresponding connector of the vehicle.

### Claim 2 (depends on 1)

Device according to claim 1, wherein the first, second and third elongated elements together substantially define a triangle, which is preferably equilateral.

### Claim 3 (depends on 1)

Device according to claim 1, wherein the third elongated element is in the form of a metal rod, which is preferably arranged to be mounted substantially horizontally at 0.2-1 m above a parking space floor.

### Claim 4 (depends on 1)

Device according to claim 1, wherein the device comprises a stepping means, arranged to stepwise change a relative angle between the third elongated element and each of the first and second elongated elements, as measured in an angular direction of the third elongated element as at least one of the first and second moving units travels to either extreme end of a path along the third elongated element along which the moving unit in question can travel, whereby the moving unit in question mechanically engages with the stepping means as a result of arriving at said extreme position.

### Claim 5 (depends on 1)

Device according to claim 1, wherein the device further comprises a digital camera, arranged to provide an image of the vehicle to the control unit, whereby the control unit is arranged to detect a relative position of the cable connecting unit in relation to the connector of the vehicle, and to control the first and second moving units so that the cable connecting unit moves towards the connector of the vehicle.

### Claim 6 (depends on 5)

Device according to claim 5, wherein the digital camera is arranged in a camera unit, in turn arranged along the third elongated element and forming a stop to the first and second moving units.

### Claim 7 (depends on 1)

Device according to claim 1, wherein the cable connecting unit comprises a cone-shaped head, arranged to align the connecting means to a geometry of the connector of the vehicle.

### Claim 8 (depends on 1)

Device according to claim 1, wherein the cable connecting unit comprises a door opening means, arranged to open a door of the vehicle to the connector of the vehicle, by the cable connecting unit pushing against the door a first time and then retracting, and wherein in that the cable connecting unit is arranged to then, by pushing forwards a second time, against the connector, connect the cable.

### Claim 9 (depends on 8)

Device according to claim 8, wherein the door opening means is arranged to be activated by the cable connecting unit being pressed towards the third elongated element.

### Claim 10

Method for automatically connecting a cable to a parked vehicle, comprising:
a) providing, at a parking space, a cable connecting device, comprising a first, a second and a third elongated element; a first moving unit, pivotally connected to a first end of the first elongated element; a second moving unit, pivotally connected to a first end of the second elongated element; a cable connecting unit, pivotally connected to a second end of the first elongated element and to a second end of the second elongated element; and a control unit, the third elongated element being fixedly mounted at a parking space, both moving units being arranged to be displaced, as controlled by the control unit, in either direction along the third elongated element, so that such displacement causes the cable connecting unit to be displaced in relation to the third elongated element;
b) causing the control unit to control the movements of the first and second moving units along the third elongated member so that the cable connector unit moves towards a connector of the vehicle; and
c) causing the control unit to control the movements of the first and second moving units along the third elongated member so that a connecting means of the cable connecting unit is pressed against a corresponding connector of the vehicle, thereby establishing an electric connection between the cable and the vehicle.
