Description

CABLE HANDLING ARRANGEMENT TECHNICAL FIELD The present invention relates to a cable handling arrangement. ln particular, theinvention relates to a cable handling arrangement configured to extend from a supplyunit and retract to a supply unit, a charging cable for a vehicle. The supply unit may e.g., be an Electric Vehicle Supply Equipment, EVSE, or a charger.

BACKGROUND Vehicles today, typically electric or hybrid vehicles, needs charging at high currents to minimize the charging time.

At high charging currents, e.g., 32 Ampere or higher, the area of the cable cross sectionneeds to be increased, to avoid excessive heat being generated in the charging cable.

To ensure a safe work environment as well as easy access to auxiliary power to the vehicle, the charging cables needs to be stored when not in use.

Document WO2013069480A1 shows a cable handling device, where the chargingcable is winded up using a reel. There are more examples of cable handling devices,which serves the purpose of a minimal storage, easy access and guided return of the cable.

A drawback with conventional solutions is that the increased charging cable crosssection results in relatively heavy cables, that wears when they are handled, e.g.,dragged over the ground. This potentially results in a reduced life span of the charging cable.

A further problem is that handling of the heavy charging cables puts strain on a user'sbody.

Another problem is the bending radius of cables with a big cross section, which results in a comparably large volumes for conventional cables reels and such.

Thus, there is a need for an improved cable handling arrangement.

OBJECTS OF THE INVENTION An objective of embodiments of the present invention is to provide a solution whichmitigates or solves the drawbacks described above.

SUMMARY The above objective is achieved by the subject matter described herein. Further advantageous implementation forms of the invention are described herein.

The advantage of this first aspect includes at least that wear on the charging cable isreduced. A further advantage is that it provides more ergonomic handling of thecharging cable for a user. The guided returned of the charging cable to its storageposition is another advantage that will reduce the risks that follows with having acharging cable dragging on the ground.

DETAILED DESCRIPTION The present disclosure relates to a cable handling system. ln particular, handling acharging cable when charging a vehicle, such as a hybrid or electrical vehicle. Thistypically involves moving an end of the charging cable, provided with a charging gun,from the charger or charging station to the vehicle, to connect and initiate charging.

The present disclosure solves the problems of cable wear and strain on the user'sbody,implemented using weights and pulleys, spring balancers or springs, attached to by providing coupled and/or serially coupled resi|ient elements, e.g.,different attachment points on the charging cable, and to an anchor point carrying partof the weight of the charging cable.

This allows a user to extend and retract the charging cable from a charging stationwithout dragging the cable on the ground. Further an anchor point of the charging cablewill carry at least part, e.g., half, of the weight of the cable, thereby reducing strain ona user's body when handling the charging cable.

The terms “resi|ient element", “resi|ient unit", “tensioning element", “tensioning unit" is used herein interchangeably.

The term “resi|ient element", used herein, denotes a unit or element configured to beconnected at two points and to extend and retract between those two points in response to being subjected to a varying pulling/dragging force. The “resilient element” typically comprises connection arrangements, e.g., clamps. ln one example the resilient element is a spring balancer provided with a housingcomprising one or more strings/wires, and is configured to allow the one or morestrings/wires to extend and retract between the two points. ln other words, the housingis attached to an anchor point and one end of the balancer-string/wire comprised bythe housing is attached to an attachment point of a charging cable. When theattachment point is subjected to a pulling/dragging force, the resilient element extends,and when the pulling/dragging force is reduced/relaxed, the resilient element retracts. ln one example the resilient element is a spring, and is configured to extend and retractbetween the two points. ln other words, the spring is typically attached to an anchorpoint at one end and one end and to an attachment point of a charging cable at theother end. ln one example the resilient element comprises one or more line members and one ormore weights, and is configured to extend and retract between the two points.Optionally, the the resilient element further comprises one or more guide members,e.g., pulleys. ln other words, the wire/rope may e.g., be attached to an anchor point atone end and to an attachment point ofa charging cable at the other end, the rope beingthreaded/running via the one or more pulleys.
