1. A door operator system for opening and closing an opening, comprising:
a door frame comprising a first frame section at a first side of the opening and a second frame section at a second side of the opening;
a door arranged to be moved between an open (O) and closed (C) position, the door being connected to the door frame, wherein the door comprises an inner face and an outer face;
a drive unit mounted on the inner face or the outer face, wherein the drive unit is moveably connected to first frame section and the drive unit is moveably connected to the second frame section, the drive unit comprising at least one motor connected to at least one energy storage device arranged to power the at least one motor, the drive unit being arranged to move the door from the closed position (C) to the open position (O);
an energy transmitting device disposed in close proximity to the door and comprising a sensing element and a transmitting activation switch responsive to the sensing element; and
an energy receiving device mounted on the inner face or the outer face,
wherein the energy transmitting device is configured to wirelessly transmit energy to the energy receiving device mounted to the door, wherein the energy receiving device is operatively connected to the at least one energy storage device for charging said energy storage device, and wherein the sensing element detects the energy receiving device within a distance allowing for energy transfer, and in response to the detection, the activation switch activates the energy transmitting device.
