    [001] The invention relates to a charging device for charging an electric vehicle at a charging station, with a first charging module on the charging station side and a second charging module on the vehicle side having contact elements interconnectable electrical, in which the charging station comprises an automatic supply device, through the actuation of the electrical contact elements of the charging station, the electrical with the contact elements of the electric vehicle can be connected.
    [002] To recharge the traction batteries of an electric vehicle at a charging station, bonded contact mounts are known to carry the charging current through electrical cables and connector mounting on the vehicle as well as non-contact devices which transmit a load current for inductively mode from a transformer bearing on the charging station side to a transformer bearing mounted on the vehicle.
    [003] Inductive load devices generally allow an adequate load, since no electrical contacts must be connected to each other and joined together, the transformer bearings can be positioned by automatic devices to each other.
    [004] Contact Hard Cover charging devices, however, are very economical to operate, as they have a superior efficiency and, thus, lower losses compared to inductive charging devices. In addition, contact-bonded loads have a simple structure and are thus particularly economical. The disadvantage is that the electrical contact elements must be joined together, which must be done manually by joining the connector parts for the most part.
    [005] A charging apparatus comprising an automatic feeding device for connecting contact elements is known from the German publication DE 10 2009 010 120 A1. With this charger, the mobility device must be positioned exactly in the charging station so that the contact elements can be merged. The document proposes to organize the vehicle on tracks - similar to a car wash, in longitudinal and transversal directions, for example, by means of optical aids, so that it is in an opposite position between it and its electrical contacts in the electrical coupling contacts at the charging station.
    [006] DE 10 2009 010 120 A1 describes the end portions in the shape of a cross-sectioned ceiling of the rod-shaped electrical contacts of the charging station and to impinge on the sloping surfaces with the introduction of the contacts of the battery system to be loaded. Furthermore, it is proposed that the charging station contacts are completely rigid, yet resiliently flexible that they can meet even small lateral deviations of the compound towards the corresponding contacts.
    [007] In general, the practical realization of a charger with connectable motorized contacts does not occur without problems. Machine connection of electrical contact elements requires very accurate detection of the position of the connected contact elements, precise mechanical alignment of the contact elements with each other, and “sensitive” behavior when connecting and disconnecting plug contacts, and to prevent damage or deterioration of electrical contact elements. In particular, ensure that the contact elements are exactly aligned when connecting to each other so that they do not cross each other. A charging device that meets these requirements typically requires a high technical and financial effort.
    [008] It was therefore an objective to provide a charging device for charging an electric vehicle, which is characterized by a relatively simple and inexpensive construction and allows a safe and very low wear and tear connecting the electrical contact elements.
    [009] This objective is achieved so that the charging station has an automatic positioning device to attach the first load module to the second load module, and that the contact elements of the first and second load module are attachable between itself without overcoming a contact force.
    [0010] While DE 10 2009 010 120 A1, a simple load proposal with motorized mobile contact elements is provided according to the invention in the loading device described in this document, in addition to producing the contact elements containing the positioned load modules each other. Furthermore, the contact elements of the two load modules are not overcome contact forces connected to each other. It was only after joining the contact elements that the contact forces of the spring elements were mechanically released between the contact elements.
    [0011] As a result, the automatic process of joining the contact elements is particularly easy and safe. Force-free mounting reduces contact wear and the risk of damage such as tilting of contact elements. However, high contact forces can be realized at the end of the connection process, which provides a good electrical connection between the load modules.
    [0012] The exact positioning of the load modules relative to each other can advantageously be provided for centering and/or by positioning elements in at least one of the load modules.
    [0013] When the load modules are mechanically locked together after assembly to ensure accurate positioning of the load modules also when connecting the electrical contact elements is particularly advantageous.
    [0014] The invention will be illustrated by the drawings and described in detail. Figures 1 to 4 show, respectively, a first and a second load module and specifically where:
    [0015] Figure 1 as unrelated items;
    [0016] Figure 2 idem, in which said second load module is shown open;
    [0017] Figure 3 in the partially assembled state;
    [0018] Figure 4 in completed condition; and
    [0019] Figures 5 to 8 show, respectively, a phase during the assembly of the first and second contact elements.
    [0020] Figure 1 shows a first and a second charging module 1 and 2 for charging an electric vehicle at a charging station, charging modules 1 and 2 are shown as still unconnected items. The first charging module 1 is part of the charging station, not shown there and, here indicated by an automatic positioning device in three mutually perpendicular directions by direction arrows with the x, y, z, movable indicators. Positioning similarly not shown pictorially recognized, for example, by a camera sensor, whose position is arranged in the second electric vehicle load module 2 and directed to the first load module 1 through multi-axis actuators, which can be deployed, for example, as a robot arm relative to the second load module 2, so after a union of load modules 1 and 2 and there arranged the contact elements 3 and 4 (Figure 5 to 8 are clearly shown) it is possible.
    [0021] The charging module 2 which is in the form of a cassette is disposed in the body of an electric vehicle. Preferred mounting locations are the area behind the front bumper, preferably behind the nameplate, and under the mobility device. Clearly this does not necessarily mean that the two load modules 1 and 2 are joined together in a vertical direction; load modules 1 and 2 can alternatively be aligned with each other so that joining can take place in a horizontal direction or in any other arbitrary direction.
    [0022] The union of load modules 1 and 2 is two pin 5 shaped positioning element holders, each with a force sensor or switch in case the first load module 1 can be connected. It is the two load modules 1, 2 aligned parallel to each other, thus touching the second load module 2 housing of the two positioning elements 5 in almost the same time. Since the distance between the two positioning elements 5 is only slightly smaller than the housing width of the second load module 2 it is due to the simultaneous activation of the positioning elements 5 to also ensure that the second load module 2 in the X direction approximately centered relative to the first load module 1 is aligned and therefore assembly positioning of the two load modules 1 and 2 can start.
    [0023] During the attachment process, there is still a precise alignment of the two load modules 1 and 2 from the first load module 1 of the centering element 6, which is shown here as a body formed with two inclined support surfaces 7. Alternatively, a cone-shaped body, for example, can also be provided as a centering element.
    [0024] As 2 to 4 illustrate, two molded guide bars 8 are inside the housing of the second load module 2, during the union of load modules 1 and 2 on the contact surfaces 7 the centering 6 is established.
    [0025] The two load modules 1 and 2 thus, during their union through the first load module 1 firstly by moving the positioning elements 5 in the Y direction, and secondly by the centering element 6 and the networks of guide 8 precisely aligned in the X direction. The approximation of the two load modules 1 and 2 in the Z direction, as well as a previously occurring convergence of load modules 1 and 2 is relative to each other also by positioning and can be supported particularly by a optical sensor.
    [0026] The housing of the second load module 2 has a protective flap 9 to which the first load module 1 is attached. Preferably, by the centering element 6 it opens automatically.
    [0027] At the end of the joining process, the two load modules 1 and 2 in 4 position shown in each other. In the last step, mechanically lock the housing of the two load modules 1 and 2 together. This can be done particularly by an actuator in the first load module 1, a screw 10 arranged of centering element 6 with a latch opening not identifiable here in the second load module 2 is connected anatomically.
    [0028] The two load modules 1 and 2 are so precisely aligned and mechanically fixed together.
    [0029] Interlocking load modules 1 and 2 now allow the first contact element 3 to connect on the first load module 1 with the second contact element 4 on the second load module 2, without allowing the load modules 1 and 2 slide against each other. On the other hand, it is also advantageous that until locking, the contact elements 3 and 4 of load modules 1 and 2 do not interact with each other, so that thus the alignment and locking positioning of load modules 1 and 2, particularly advantageously, does not suffer mechanical influence from the contact elements 3 and 4.
    [0030] The first load module 1 includes two contact openings 17 (Identified in 1 to 3 ) so that the first contact elements 3 can be extended by a motor drive. Of the second contact elements 4 in 2 to 4, in each case there is an outer surface of a spring element 11 to produce a contact force, and in each case a recognizable metal strip 18. Metal strips 18 forming on an outer surface of said second load module 2 of electrical terminals 19, which are connectable to the electrical system of the electric vehicle.
    [0031] The first and second contact elements 3 and 4 are in Figures 5 to 8 shown in different phases of union. These union phases do not correspond to phases 1 to 4 of load modules assembly illustrated in 1 and 2 . The union of contact elements 3 and 4 starts only when the load modules 1 and 2 are completely connected as shown in Figure 4.
    [0032] Figures 5 to 8, respectively, show a sectional view through the second load module 2 along a second contact element,4 and by a first contact element 3 Which, of the first load module 1 in the 4 second attachable contact element. Details of the first load module 1 are in 5 through 8 not shown. It was particularly dispensed with, also in the representation of an actuator system, that the first contact element 3 towards the second contact element 4 changes. These actuators may, in particular, have electromotive, electromagnetic, hydraulic or pneumatic components, which are preferably operated fully automatically by an electronic control system.
    [0033] The second contact element 4 which is arranged in the housing of the second load module 2, here included as an omega spring element 11 in which the two juxtaposed contact plates 12 surround. The end portions of the legs 13, spring elements 11 and contact sheets 12 are equipped with a two-piece contact bracket 14 connected. In the spring element 11 and contact plates 12 of opposite side, the two pieces 14a, 14b diverge, the contact carrier 14 bevels 15 from there towards the outer side of the second contact element 4 .
    [0034] The first contact element 3 has a handle 20 and the handle 20 surrounds the guide sleeve 16 on the opposite handle 20 is slidable. Both the handles 20, as well as the guide sleeve 16, are positioned by a not-illustrated actuator towards the second contact element 4, wherein the first and second contact elements 3 and 4 are connected together or are separable between themselves. Connecting the first and second contact elements 3 and 4 is shown in phases of Figures 5 to 8.
    [0035] Figure 5, the first and second contact elements 3 and 4 not yet connected. At the beginning of the joining process the handles 20 and the guide sleeve 16 are together in the direction of the second contact element 4 moved. The free end portions of the handle 20 is from the guide sleeve 16 encircled.
    [0036] In the next step, which Figure 6 shows, the guide sleeve 16 meets the chamfer 15 of the contact conveyor 14 and thus forces the two parts 14a, 14b into the contact conveyor 14 and therefore also contacts the conveyor 14 of associated leg 13 of spring element 11 and the two separate contact plates 12 . Between the contact plates 12 created as a space 21 that is far enough away from the friction insert of handles 20, with the result that 7 is shown during insertion, no contact force on the handle 20 so that no mechanical wear due to friction between contact elements 3 and 4 arise. Only when the handle 20 has its intended end position, a contact force to the flat plug 20 is generated. As shown in Figure 8, this is achieved that the guide sleeve 16 against the flat plug 20 and shifted from the second contact element 4 is carried, in which the parts 14a. 14b the contact carrier 14 by the spring element 11 are brought together again and the leg 13 of the spring element 11 from the contact plates 12 to the outer surfaces of the handle 20 are pressed together.
    [0037] In the same way, the separation of the electrical components of the two contact elements 3 and 4 can be conducted simultaneously in which the summarized sequence from 5 to 8 is reversed.
