An arrangement for cable unwinding and winding in an electrically driven vehicle, the arrangement comprising: - a cable reel for a cable, - a cable guide arrangement for receiving and guiding the cable, - the cable guide arrangement comprising three contacting surfaces (4a, 4b, 4c), arranged parallel and in a triangle arrangement, - the contacting surfaces (4a, 4b, 4c) in the cable guide arrangement being arranged and dimensioned such that the cable arranged between one of the contacting surfaces on its first side and two of the contacting surfaces on its second side bends on a surface of at least one of the contacting surfaces (4a, 4b, 4c), - the arrangement further comprising a control arm and a controlling arrangement, the controlling arrangement comprising - a force measuring system provided in at least one of the contacting surfaces (4a, 4b, 4c) and arranged to measure force caused by the cable against said contacting surface(s), the force measuring system providing a force, - a control arm sensor arrangement arranged to detect the direction in which the control arm is pointing in relation to the longitudinal axis of the electrically driven vehicle, and for providing a control arm angle information, wherein - the cable guide arrangement comprises a rotational axis (Xc) parallel with the normal axis (Xn) of the triangle arrangement, - the rotational axis (Xc) of the cable guide arrangement and the centre axis (Xr) of the cable reel are arranged in a same direction, - the cable guide arrangement is attached pivotally in the control arm, and - the control arm is arranged pivotally to a centre axis (Xr) of the cable reel so that - the rotational axis (Xc) of the cable guide arrangement lies at a first distance from the centre axis (Xr) of the cable reel and have an ability to rotate in relation to the cable reel, and - a triangle sensor arrangement is arranged to evaluate a rotation angle of the triangle arrangement in respect to the control arm for providing a triangle angle information, and wherein the controlling arrangement is arranged to calculate an estimate of forces focusing on the cable based on the force, the control arm angle information and the triangle angle information. -
