    The invention relates to a charging cable assembly for the transmission of electrical energy between a power station and an electrically drivable vehicle with a charging cable outer sheath, in which at least one conductor cable with a conductor outer sheath and at least one coolant line with a heat transfer surface are arranged.
    Motor vehicles with at least one electric motor as the drive motor must be charged at charging stations so that they can store the energy necessary for driving the motor vehicle. For this purpose, the motor vehicle has an electrical energy store and a plug-in device, which can be connected directly or indirectly to a power grid station by means of a charging cable arrangement. In order to accelerate the charging process, quick charging stations are used as power grid stations, whereby strong electrical currents are transmitted. These electrical currents cause, among other things, heating of the electrical conductor cables provided in the charging cable arrangement. In order to achieve small cable cross-sections, a cooling device is necessary in the charging cable arrangement.
    From the prior art, such as EP 2 652 754 B1, DE 10 2011 100 389 A1 or US 9,321,362 B2, charging cable assemblies are known in which at least one electrical conductor cable is provided with a coolant line that has a heat transfer surface to cool the conductor cable. It has been shown, however, that such arrangements require a high cooling capacity in order to limit excessive heating of the electrical conductor cables.
    The object of the invention is therefore to ensure the most efficient possible cooling of the conductor cable in a cost-effective and simple manner.
    This object is achieved in that at least one heat transfer layer is provided, which at least partially rests against the heat transfer surface and the outer sheathing of the conductor. In this way, a homogeneous distribution of the temperature and heat flux density present on the outer sheathing of the conductor is ensured. The outer sheathing of the conductor transfers the heat to the heat transfer layer, which in turn exchanges heat with the coolant lines.
    In a particularly advantageous embodiment, the heat transfer layer has silver, copper and / or aluminum as the heat conducting material.
    In a particularly advantageous manner, the heat transfer layer is flexible in the form of a network, grid or film, which makes it possible to deform the heat transfer layer in a simple manner and accordingly adapt the outer sheathing of the conductor.
    In a particularly compact advantageous embodiment, two conductor cables and two coolant lines are arranged alternately clockwise, with a heat transfer layer being provided which encompasses the opposite sides of the heat transfer surfaces of the coolant lines and the mutually facing sides of the conductor outer sheaths of the conductor cable. In addition or separately, a heat transfer layer can be provided which encompasses the sides of the heat transfer surfaces of the coolant lines and the outer conductor sheaths of the conductor cables facing away from one another. In particular, this layer, which surrounds the sides of the outer conductor sheaths of the conductor cables facing away from one another, can additionally serve as EM shielding when operating with alternating current. In order to ensure the largest possible contact surfaces for lateral heat transfer, a protective conductor and / or signal lines and / or filler material can be provided in the charging cable arrangement, which increase the compactness of the charging cable arrangement.
    The invention is explained in more detail with reference to a drawing, in which: FIG. 1 shows a perspective view of a plug-in motor vehicle which is connected to a stationary power supply station, and FIG. 2 shows a cross-sectional view of a charging cable arrangement according to the invention.
    FIG. 1 shows a perspective view of a motor vehicle 2, the vehicle body 4 of which has a charging connection device 6. This charging connection device 6 is connected to a stationary electrical power grid station 10 via a charging cable arrangement 8.
    Figure 2 shows the charging cable arrangement 8 in a cross-sectional view. The charging cable arrangement 8 here has a charging cable outer sheath 12 in which, in the present exemplary embodiment, two current conductor cables 14, 16 and two coolant lines 18, 20 are arranged. Furthermore, a protective conductor 22, signal lines 24 and filling material 26 are provided. The conductor cables 14, 16 each have an outer conductor sheath 28, 30. The coolant lines 18, 20 each have a heat transfer surface 32, 34. According to the invention, a first and a second heat transfer layer 36, 38 are now provided. The heat transfer layers 36, 38 consist essentially of copper and are designed in the form of a network in order to be able to be laid flexibly. The two coolant lines 18, 20 and the two current conductor cables 14, 16 are arranged alternately clockwise in the present exemplary embodiment. Here, the first heat transfer layer 36 is provided in such a way that it encompasses the sides of the heat transfer surfaces 32, 34 of the coolant lines 18, 20 facing away from each other and the sides of the outer conductor sheath 28, 30 of the conductor cables 14, 16 facing each other. The second heat transfer layer 38 is provided in such a way that it encompasses the sides of the heat transfer surfaces 32, 34 of the coolant lines 18, 20 that are facing away from one another and the sides of the outer conductor sheaths 28, 30 of the conductor cables 14, 16 that are facing away from one another.
    It should be clear that an optimal heat exchange in the charging cable assembly 8 is guaranteed in this way.
