    Loading device and method for loading
    The invention relates to a charging device, in particular for a vehicle.
    Moreover, the invention relates to a use of such a charging device.
    Furthermore, the invention relates to an electric vehicle with such a charging device.
    Furthermore, the invention relates to a method for loading, in particular a vehicle, in particular using such a charging device.
    For several years, electric vehicles or plug-in hybrid vehicles, in particular at least partially electrically powered cars, are produced or sold as standard by various vehicle manufacturers.
    A plurality of electric vehicles or plug-in hybrid vehicles known from the prior art can be charged via a connecting element arranged on a cable for current or voltage transmission, which can be connected to a further connecting element arranged on the vehicle to produce a conductive connection. Wired charging has the advantage that this with a suitably trained cable quasi lossless feasible high charging power is possible. Furthermore, a wired charging of an electric vehicle is associated with rather low costs due to cables and plugs or connecting elements that can be produced relatively inexpensively.
    Different vehicle manufacturers often arrange a socket or a connecting element for connection to the connecting element arranged on the cable at different positions on the vehicle. For example, this may be integrated laterally, front or rear on or in the vehicle. If an electric vehicle is to be charged, it must consequently be positioned or parked differently from the cable or connecting element arranged thereon or a cable must be designed to be correspondingly long in order to establish a connection for charging the vehicle. A predetermined positioning of the electric vehicle is relatively uncomfortable and a long cable increases its cost. Next, a connection of the two
    Connecting elements usually by hand, which in turn is expensive. It can also be quite occurrence that forgot to connect and thus the electric vehicle is not charged and therefore not in operation is acceptable. In addition, a long cable loosely around causes several problems: it quickly becomes dirty, can present a trip hazard, can become entangled and become a target of vandalism.
    To overcome these disadvantages, research has been carried out for some time on a standard producible inductive charging device. Inductive charging is more convenient than wired charging, as no doggy plugging and unplugging is necessary and inductive charging is fully automated. However, this requires a very accurate positioning of a arranged in the vehicle floor secondary coil on a arranged in the bottom of a parking space primary coil. Currently, only a charging power of about 3 kW to 4 kW is possible with an inductive charging device, with an efficiency is also low. In addition, the necessary electronics is expensive and expensive to manufacture and also has the entire part of a vehicle-mounted loader a high weight. Another disadvantage of inductive charging is the electromagnetic compatibility and the associated necessary shielding and / or filtering measures, which are costly. Further, electromagnetic fields and electromagnetic energy transmission have little acceptance in society, and therefore selling an electric vehicle with an inductive charging device may be difficult even in the case of lower manufacturing cost.
    Although devices for charging a vehicle with punctual advantages are known from the prior art, but these all have several disadvantages.
    This is where the invention starts. The object of the invention is to provide a loading device of the type mentioned, which allows a comfortable and automated loading of a vehicle with a high charging power.
    Another object is to provide a use of such a charging device.
    Furthermore, the aim is to provide an electric vehicle of the type mentioned, which can be loaded comfortably and automatically with a high charging power.
    It is also an object to provide a method of the type mentioned, with which energy is exchanged comfortably and automatically.
    The object is achieved in that in a charging device of the type mentioned a contacting plate is formed with a plurality of positioning and at least one connecting element is provided for power transmission, wherein the connecting element engages in a merging with the contacting plate position independent and yielding in one of the positioning elements ,
    An advantage achieved by the invention is to be seen in particular in that a convenient charging example of a vehicle or in this arranged storage unit for electrical energy is made possible by the merging of the connecting element with the contacting plate. The contacting plate is designed so that it can be fastened to or in a vehicle. Alternatively, the contacting plate can also be fixed stationarily at a charging station. According to the invention it can be provided that both the merging and the latching takes place automatically. Consequently, compared to the prior art, no cumbersome manual involvement in establishing a connection between a power supply and, for example, a vehicle is more necessary. Due to the large number of positioning elements and the automatic and position-independent engagement of the connecting element, moreover, no exact positioning of a vehicle on or in which the contacting plate can be fastened is more necessary. In particular, when comparing with the inductive charging of an electric vehicle or plug-in hybrid vehicle, this results in a great advantage, since an efficiency in inductive charging decreases significantly with increasing offset of the coils. In this case, the contacting plate with the positioning elements is preferably designed in such a way that when the connecting element is in contact with it, it engages in one of the positioning elements independently of a position of positioning, preferably in a form-fitting manner. With a charging device according to the invention, on the one hand, a storage unit for energy in a vehicle can be charged and, on the other hand, electrical energy is from one
    Storage unit traceable to a power grid. So it is a bidirectional energy exchange between two energy systems possible.
    It is preferably provided that the contacting plate is constructed in a multi-layered manner, with at least one insulating layer and at least one contact layer alternately being provided in an average thereof. The insulating layer may be formed, for example, from plastic such as polyester, in particular polyactide (PLA). PLA may have a dielectric strength of up to about 20,000 V / mm, whereby the insulating layer may be formed relatively thin, whereas the contact layer for making electrical contact or for transmitting electrical energy is designed to be conductive. Advantageously, the insulating layer may also be formed of polyvinyl chloride (PVC), polyethylene terephthalate (PET) or acrylonitrile-butadiene-styrene (ABS). Overall, the contacting plate can be made as thin as possible in order to minimize its own weight. It is advantageous, however, if the insulating layer is made thicker than the dielectric strength of the material forming it, for example about 20 times as thick.
    It is advantageous if the contacting plate comprises a plurality of, in a plan view, preferably polygonal, in particular hexagonal, cells each having a positioning element. The cells are regularly arranged on the contacting plate and thus enclose an entire area of this. It can be provided that a diameter of a cell is about 40 mm to 120 mm, for example about 70 mm.
    In this case, it can preferably be provided that each cell has in particular cone-shaped recesses with a tip in a center of the cell. The recesses preferably comprise an entire height or thickness of the contacting plate, which may for example be about 10 mm to 30 mm thick. Each cell with the conical recess represents a positioning element. An angle of the recesses may advantageously have a certain minimum steepness, for example in a range of 15 ° to 35 °, in particular in a range of 20 ° to 30 °, preferably about 25 ° ,
    Conveniently, each cone-shaped recess comprises at least one hollow cylindrical, coaxial recess. According to the invention, for example, one, three or five recesses may be provided. If a plurality of recesses are provided, it is advantageous if they are formed differently deep, wherein a recess which is located farthest inside or closest to the tip of the cone-shaped recess, may have a relatively largest depth or furthest towards the lower end the contacting plate can reach.
    For this purpose, it is further advantageous if the at least one contact layer is arranged in the at least one coaxial recess. According to the invention it can be provided that the entire contacting plate is formed of an electrically non-conductive or insulating material, which constitutes the insulating layer. The at least one contact layer or electrically conductive layer can then be arranged in the at least one recess. If a three-phase connection for the transmission of alternating voltage or alternating current or three-phase current between the contacting plate or a positioning element and the connecting element is to be produced, it can advantageously be provided that three coaxial recesses are arranged in each cell or in each positioning element. In each case, a contact layer is arranged annularly or also coaxially in each recess. As a result of the annular formation of the at least one contact layer, it may be made thin, for example thinner than 2 mm, in particular approximately 1 mm, and nevertheless have a large cross-sectional area, since a circumferential length of the contact layer is greater by at least an order of magnitude than its thickness. Due to the large cross-sectional area, a large charging capacity is achievable, whereby a charging time can be reduced.
    The contact layers or the electrically conductive layers can be connected to one another between the individual positioning elements, preferably via or in the entire contacting plate. In the case of a three-phase case, this means that the contact layer for the respectively identical phase extends over the entire contacting plate and thus in each case from one positioning element to the next. It is therefore provided per conductor, a contact layer. In order to achieve that a cross-sectional area of each contact layer is the same size, the contact layers can become thicker the farther inward in the direction of the cone tip they are arranged.
    In each case an insulating layer is further disposed between each contact layer, which also extends over the entire contacting plate, wherein in each case an insulating layer closes the contacting plate downwards and upwards. In the three-phase case, therefore, four insulating layers are provided. Furthermore, it is favorable if the contact layers are each formed with a lower height than the insulating layers or do not extend completely to an upper end of the insulating layers in order to avoid undesired flashovers and contacts. The contact layers and insulating layers are preferably connected together inextricably by a single high application of force. Such a connection may, for. B. be made by pressing, gluing or screwing. The advantage here is that the individual layers are layered or sandwiched without undercuts connected to each other and the contacting plate is thus inexpensive to produce.
    In addition to a three-phase connection, the charging device can also be designed correspondingly for a five-phase connection for the transmission of alternating voltage between the contacting plate or a positioning element and a connecting element. For this purpose, five coaxial recesses are provided in each cell, again in each recess a contact layer is arranged. A layered structure of the contacting plate takes place in accordance with the three-phase case.
    For the transmission of electrical energy from the contacting plate to a storage unit, a power cable per conductive contact layer can be connected to it over an entire length or width of the contacting plate at the edge of one or two sides thereof. The power cables are advantageously attached to the contacting plate so that a punctiform high current load is avoided.
    It can be provided that the contacting plate is arranged on an electric vehicle, in particular approximately on the bottom side in order to allow the most flexible possible positioning of the electric vehicle. Preferably, it can be provided that the contacting plate is at least 40 cm by 25 cm, for example about 80 cm by 60 cm, large. In any case, it is advantageous if it is so large that the electric vehicle can be positioned anywhere on a parking space. At the same time, this should be made small enough to allow automatic engagement of a connecting element and not unnecessarily increase a weight of the electric vehicle. It can also be provided that the contacting plate is arranged on the bottom side on a plug-in hybrid vehicle. Next, the contacting plate z. B. also be mounted next to a front or rear license plate of a vehicle or installed inside a vehicle.
    It may be further favorable if a covering device is provided which covers the contacting plate when not in use. Disuse is always given when a charging device of a vehicle is not charged or the contacting plate is not connected to a connecting element. The covering device may preferably be foldable and protects, for example, from dirt and / or moisture. Preferably, an opening or closing of the cover device is automated, which is held in position with magnets, for example. It is also conceivable that a spring is provided to bring the cover from a first to a second position. It may also be favorable if the covering device also covers a region of the contacting plate in a connected state, which is not connected to the connecting element.
    In order to enable fully automated loading, it can further be provided that the connecting element can be positioned in each of the positioning elements, wherein the connecting element is designed in particular conically with a blunt tip. This ensures that the connecting element can be positively positioned in each of the positioning of the contacting plate. The blunt tip or the blunt end allows an automatic and resilient engagement of the connecting element in one of the positioning elements. There is no great resistance to overcome in such training. In particular, upon impact of the connecting element on the contacting plate in a position between two positioning elements, an automatic locking into one of the desired positions is made possible by the shape of the connecting element. Particularly preferably, the end of the connecting element has a hemispherical rounding with a radius of less than 5 mm, in particular 1 mm or smaller. When choosing the material of the connecting element, particular care should be taken to ensure that it has the required hardness in order to minimize possible material abrasion and frictional forces to be overcome during the assembly. This can be a
    Surface of the connecting element to be coated, for. As with polytetrafluoroethylene (PTFE), wherein it is beneficial, although a surface of the positioning is coated with PTFE to minimize a coefficient of friction during merging.
    According to the invention it can further be provided that the cone of the connecting element has an angle or a conical reduction in the range of 50 ° to 80 °, in particular in the range of 55 ° to 75 °, preferably about 65 ° .Thus this slips when Merging or queuing at the contacting plate particularly well in one of the positioning and it must be overcome little frictional resistance.
    It is expedient if at least one contact body is arranged within the connecting element, which can be brought partially out of the connecting element when force is applied in order to connect to the contact layer of a positioning element, wherein a contact region is arranged in the contacting plate. In particular, it may be provided that a plurality of contact bodies are arranged in the connecting element, which are preferably arranged coaxially with each other according to the arranged in the coaxial recesses of the contacting plate contact layers. Depending on whether a three-phase or five-phase connection is to be made for the transmission of alternating voltage, correspondingly three or five hollow cylindrical or annular contact bodies can be provided. It can further be provided that each coaxial contact body each of several, z. B. three, six or eight, sections or segments. As a result of the hollow-cylindrical design of the at least one contact body, the latter can in turn be made thin, for example thinner than 2 mm, in particular approximately 1 mm, and nevertheless have a large cross-sectional area, since a length or a circumference of the contact body is greater by at least an order of magnitude than its Thickness. Due to the large cross-sectional area, a large charging capacity is achievable, whereby a charging time can be reduced.
    According to the invention, a transmission of direct current can also be provided. For this purpose, two connecting elements may be provided, in each of which a contact body, each with a phase is arranged. The positioning elements can be used to hold the
    Connecting elements should be formed in pairs and accordingly each comprise a contact layer with a phase. It is advantageous if the contact bodies are always arranged within the connecting element and can be pushed out of this position partially only after a positive reception of the connecting element by a positioning element in order to prevent bending and / or touching the contact body or the like. In a position partially outside of the connecting element or a position at which changes a shape of the connecting element, the segments are bounded in the direction of the cone of the connecting element in each case in all directions thereof, wherein the cone is preferably made of an electrically non-conductive material or Insulating material is made. The contact bodies can therefore be externally electrically insulated except for a region required for an electrical contact. It is expedient if at one of the tip of the cone opposite side, a pressure medium is provided, with which the contact bodies can be brought by force from the cone of the connecting element, wherein the contact bodies are preferably releasably fixed in this position outside of the connecting means. It can be provided that these can be brought by a renewed actuation of the pressure medium from this position releasably and again in its initial position within the connecting means.
    According to the invention, it can further be provided that, in a first step, the positive connection between the connecting element and a positioning element takes place, after which the two elements are preferably releasably connectable to a contact between the at least one contact layer and the at least one contact body. Only after completion of these steps, the transmission of electrical energy to an arranged in a vehicle accumulator or its control and / or power electronics.
    For this purpose, a first mechanical probe or sensor can be provided which determines whether the contact bodies have been pushed completely out of the connecting element. In addition, a second button or sensor may be present, which z. B. can be arranged on the outside of the positioning cone of the connecting element and is actuated upon contact with a positioning element. Both sensors or buttons may preferably be connected to each other with an AND link, whereby both must be actuated to z. B. to allow a flow of electricity at all. Furthermore, these sensors also allow an immediate interruption of the flow of current when the elements are separated from each other.
    It is particularly favorable if the connecting element is arranged on a lifting device. The lifting device can advantageously be formed by a linear actuator drive and / or be designed as a robot arm and be arranged on a floor of a parking lot, which can be as flat as possible preferably flush with the ground when not in use. It is particularly favorable when the connecting element is arranged on the lifting device such that it is always aligned approximately parallel to the ground and / or to the contacting plate. Furthermore, the connecting element can be arranged to be movable or deflectable on the lifting device in order to enable an automatic and resilient latching into one of the positioning elements when it is resting against the contacting plate. This lateral or lateral deflection in the x-direction and in the y-direction can be done for example via springs. An x-y plane corresponds to a plane in which the individual cells of the contacting plate are arranged, with a z-direction being perpendicular thereto. The positioning element is deflected according to this plane in the x direction and in the y direction. Such springs can also allow the release of the connection an independent return of the connecting element in its initial position.
    For this it is further favorable when the lifting device is automatically moved. Thus, both a positioning of the connecting element in one of the positioning of the contacting plate as well as a transmission of electrical energy is automated and automatic. It is neither a manual matching of fastener and vehicle nor an exact positioning of the vehicle necessary because multiple options or positioning elements are present to accommodate the connecting element. Due to this, the z. B. designed as a robotic arm lifting device in an axis (z-direction) to be movable and must perform only an upward or downward movement. For final engagement, the connecting element arranged on the lifting device can be deflected laterally by at least one cell circumferential radius (in the x-direction and y-direction), so that it always occupies a discrete position. It can be further provided that the
    Production of a conductive connection between the connecting element and one of the positioning elements autonomously or automatically performed by the lifting device to automatically charge a storage unit for electrical energy in a vehicle.
    The charging device according to the invention enables a continuous connection of an electric vehicle or plug-in hybrid vehicle to a power grid. This allows controlled charging and avoids expensive peak consumption times. For this purpose, a control unit and / or a communication unit may be present with which the vehicle or the storage unit communicates with the power grid or the stationary part of the charging device. Such communication is advantageously wireless and automated.
    A use of a charging device according to the invention is advantageously carried out when autonomously charging a storage unit for electrical energy in a vehicle.
    The further aim is achieved if, in an electric vehicle of the type mentioned above, a contacting plate with a plurality of positioning elements is arranged on the bottom side of the electric vehicle and at least one connecting element is provided for power transmission, which engages position-independent and yielding in one of the positioning elements when merging with the contacting plate ,
    It is particularly advantageous that an automated and autonomous charging of the electric vehicle or a storage unit in the same is possible by the position-independent and resilient engagement of the connecting element in one of the positioning of the contacting. On the one hand, it is possible to charge a memory unit and, on the other hand, electrical energy can also be fed back into the power grid. In this case, the contacting plate is preferably arranged on the electric vehicle such that it can be positioned approximately anywhere on a parking space. By the automatic latching no handling with a cable or the like is necessary. According to the invention, it can further be provided that the contacting plate has little weight and thus does not appreciably increase the weight of the electric vehicle.
    The procedural goal is achieved if, in a method of the type mentioned, at least one connecting element for power transmission is combined with a contacting plate arranged on the vehicle, wherein the connecting element in a contact with the contacting plate position independent and yielding in one of a plurality of arranged on this positioning is engaged.
    An advantage of the method according to the invention is to be seen in particular in that a connection between the contacting plate and the connecting element is made automatically by the position-independent and resilient engagement of the connecting element. If the connecting element is located at any point on the contacting plate, then it is automatically or autonomously engaged in one of the positioning elements which are arranged on the contacting plate. For this purpose, it is preferably provided that the connecting element is positively received by one of the positioning elements. The positioning elements are stored in particular in each case a hexagonal cell, each cell has conical recesses and each positioning of the contacting plate is designed to be identical. With a method according to the invention, for example, an electric vehicle or plug-in hybrid vehicle can be supplied with electrical energy efficiently and conveniently, wherein the contacting plate is preferably arranged on or in this.
    It can preferably be provided that at least one arranged within the connecting element contact body is pressed in positive contact of the connecting element with a positioning in a arranged in a coaxial recess of the positioning part of a contact layer and non-positively releasably connected. For this purpose, it is necessary that the contact body is always arranged inside the connecting element except when a conductive connection is being produced. It is advantageous if a plurality of coaxially arranged contact body are provided, which are pressed to produce a conductive connection in equally coaxial recesses of a positioning. Simultaneously with the production of a conductive connection, the two elements are also non-positively connected to each other to allow an uninterrupted transmission of electrical energy. At a
    Producing a three-phase connection, three coaxially arranged contact bodies are positioned with the application of force in three coaxially arranged recesses of a positioning element, wherein the three contact bodies of the connecting element in each case in several sections or segments, for example in three, six or eight, are divided. In each case a contact layer is mounted in the recesses of the positioning, in the direction of which the contact bodies are pushed.
    It is useful if, when taking a predetermined position of the vehicle with the contacting plate, the connecting element is moved automatically with a lifting device to the contacting plate. The lifting device may, for. B. be formed by a linear actuator drives and / or as a robot arm. The lifting device is preferably arranged in a floor of a parking lot or the like and moved in an axis (z-direction) to rest at an arbitrary position on the contacting plate, wherein the contacting plate is preferably arranged on the bottom side on a vehicle. A connection between the contacting plate and connecting element is thus made free of manual support. The connecting element is preferably moved in an orientation approximately parallel to the ground to the contacting plate, wherein the contacting plate can be arranged on the bottom side on a vehicle. In the event of an abutment against the contacting plate, the connecting element is laterally deflected by up to one cell circumferential radius (in the x direction and in the y direction), so that a discrete position in one of the positioning elements is finally assumed by the latter. For this purpose, the connecting element is preferably arranged movable or deflectable on the lifting device, for example with at least one spring. To protect the lifting device when not in use, a covering device can be provided for this.
    In this case, a position determination system may be provided, which indicates to a vehicle driver whether a position is or was occupied by the vehicle, in which such an automated connection of the connecting element with a positioning of the contacting plate is possible.
    It can preferably be provided that upon complete contact of the contact body of the connecting element with the contact layer of the positioning and after an automatic non-positive connection of the positioning with the connecting element, a storage unit is charged in the vehicle. In a first step, therefore, a connection between the contacting plate and the connecting element is produced automatically and in a second step, the memory unit of a vehicle is in turn charged automatically. Due to the coaxial design of the at least one contact layer and the at least one contact body, these can be formed thin and still have a large cross-sectional area, whereby a charging cycle with a high charging power is performed by.
    Preference may be further provided that after a completed charging cycle, the non-positive connection is released automatically and the connecting element is moved with the lifting device in a starting position. The starting position can be arranged in a floor of a parking space for a vehicle. For loading a vehicle or a memory unit arranged in this memory unit, it is parked in an arbitrary position in a parking lot, after which a connecting element is brought into contact with a contacting plate arranged on this vehicle and subsequently a charging device of the vehicle is charged. The whole thing is done automatically or autonomously and without the involvement of a driver. Even after a completed charging cycle no manual participation is necessary, as well as a release of the connecting element of the contacting plate is automated and done automatically.
    Advantageously, moreover, it can be provided that, when the contacting plate is not in use, it is covered in a watertight manner, in particular, by a covering device. In this case, opening and / or closing of the covering device after taking a position for loading is preferably carried out automatically. With the covering the contacting plate is also protected from dirt and / or damage. For this purpose, the covering device may be coated. Furthermore, a heating device may be provided in order to avoid icing or the like of the covering device, in particular in winter.

    1 shows a loading device 1 according to the invention with a contacting plate 2, on which a multiplicity of positioning elements 3 are arranged. Furthermore, FIG. 1 shows a connecting element 4, which is received by one of the positioning elements 3. The contacting plate 2 is constructed multi-layered.
    In Fig. 2a to 2c, a schematic structure of the contacting plate 2 is shown. Fig. 2a shows that this is divided into uniform, hexagonal cells 7, wherein the cells 7 are arranged regularly. Each of these cells 7 comprises a cone-shaped recess 8 in the direction of the center thereof, as shown in FIGS. 2 b and 2 c, which each show a section through the contacting plate 2 according to FIG. 2 a.
    3a to 3c show further views of the contacting plate 2, in which the layered structure of this is apparent, with 3a shows a view of the outward side of the contacting plate and Fig. 3b and 3c each have a section through the contacting plate 2 of FIG. 3a. In the contacting plate 2, a contact layer 6 is alternately arranged with an insulating layer 5, wherein three contact layers 6 are provided for producing a three-phase connection, in order to subsequently transmit AC voltage or three-phase current. In a plan view according to FIG. 3 a, it can further be seen that recesses 9 are provided in the conical recesses 8, in which the contact layer 6 is arranged. The
    Recesses 9 are preferably hollow cylindrical and coaxial. Further, these can each have a different depth, wherein the recesses 9 can be considered relatively all formed approximately equally deep. Furthermore, it can be provided that the contact layer 6 extends over the entire contacting plate 2 or in each case a contact layer 6 of a recess 9 of a positioning element 3 is connected to a corresponding contact layer 6 of a next positioning element 3. It is advantageous if the entire remaining part of the contacting plate 2 consists of the or more insulating layers 5.
    A bottom view of an inner side of the contacting plate 2 is shown in Fig. 4, wherein it can be seen that the areas between the recesses 8 are excluded from the contacting plate 2 in order to reduce material and weight thereof.
    A further view of the contacting plate 2 is shown in Fig. 5, in which the layered structure can be seen, wherein the contact layers 6 are each arranged in the recesses 9. The entire contacting plate 2 is constructed in layers, with the insulating layer 5 and the contact layer 6 alternating in each case.
    6a to 6c respectively show the charging device 1 with a contacting plate 2 with a connecting element 4 arranged thereon, wherein no conductive connection is made. However, the connecting element 4 is positively received by one of the positioning elements 3 of the contacting plate 2 or the connecting element 4 is discretely aligned in a center of a cell 7. For this purpose, it may be provided that the connecting element 4 is in particular formed conically with a blunt or slightly rounded tip or end. This ensures that the connecting element 4 can be positioned positively in each of the positioning elements 3 of the contacting plate 2. The blunt tip allows an automatic and resilient engagement of the connecting element 4 in one of the positioning elements 3. It must be overcome by such training no great resistance. Further, the cone of the connecting element 4 may be completed with a bearing surface, which has a larger diameter than the largest diameter of the cone. This ensures that the connecting element 4 occupies a straight end position in one of the positioning elements 3 and not skewed stuck in this. For this purpose, an axis of rotation of the connecting element 4 can be coaxial with the conical recess 8 of the positioning element 3.
    FIGS. 7a to 7d show a loading device 1 with a contacting plate 2 with connecting element 4 arranged thereon, wherein it is positively connected by one of the positioning elements 3 and a conductive connection is established. For this purpose, contact body 10 are partially pressed out of the connecting element 4 and occur during or after positive contact of the elements 3, 4 with each other in order to allow a subsequent uninterrupted charging. There is at least one contact body 10 is provided, it is favorable, however, if a plurality of coaxially arranged contact body 10 are arranged in the connecting element 4, which are formed according to the contact layer 6. It has been found that each coaxial contact body 10 is subdivided into at least six segments in order to increase their flexibility and thus to increase a mechanical contact resistance with the contacting plate 2, so that the individual segments bear against the contact layers 6 of the positioning element 3 with a certain pressure Press to reduce electrical contact resistance. Simultaneously with the production of the conductive connection, the connecting element 4 is frictionally, releasably connected to the positioning element 3 of the contacting plate 2, for example with a spring. To ensure that only after positive connection of the two connecting elements 3, 4, a conductive connection can be produced, magnets may be provided in the connecting element 4. The magnets ensure that the connecting element 4 is aligned on a surface of the contacting plate 2 in a cell 7 without the contact bodies 10 being prematurely pressed out of the connecting element 4.
    8a again shows a charging device 1, in which the contact bodies 10 of the connecting element 4 are conductively connected to the contact layers 6 of the positioning element 3. FIG. 8b shows a section of the connection according to FIG. 8a. The contact bodies 10 of the connecting element 4 are in contact with the contact layers 6 of the positioning element 3. Between the contact layers 6, the insulating layers 5 are arranged. In Fig. 8a and 8b, a three-phase connection for the transmission of AC voltage between the contacting plate 2 and a positioning element 3 and the connecting element 4 is made. For this purpose, three coaxial recesses 9 are provided in each cell 7 or in each positioning element 3 and arranged in each recess 9 in each case a contact layer 6 annular or coaxial. By the annular formation of the contact layer 6, this may be formed thin, for example, thinner than 2 mm, in particular about 1 mm, and still have a large cross-sectional area, since a circumferential length of the contact layer 6 is greater by at least an order of magnitude than its thickness. Due to the large cross-sectional area, a large charging capacity is achievable, whereby a charging time can be reduced. Accordingly, three annular contact body 10 are arranged in the connecting element 4, which are divided into several segments per ring.
    In addition to a three-phase connection, the charging device 1 can also be configured correspondingly for a five-phase connection between contacting plate 2 or a positioning element 3 and connecting element 4. For this purpose, five coaxial recesses 9 are provided in each cell 7, in turn, in each recess 9, a contact layer 6 is arranged. A layered structure of the contacting plate 2 takes place in accordance with the three-phase case.
    In addition, a charging device 1 according to the invention can also be designed for a transmission of direct current. For this purpose, two connecting elements 4 may be provided, in each of which a contact body 10 is arranged, each having a phase. The positioning elements 3 may be designed to receive the connecting elements 4 in pairs and accordingly each comprise a contact layer 6 with a phase.
    The contacting plate 2 can also be formed so that it comprises, for example, cone-shaped connecting elements 4 and for establishing a connection, a positioning element 3 with, for example, a conical recess on one of the connecting elements 4 can be placed.
    It can be provided with advantage that the contacting plate 2, as shown in FIG. 9, is arranged in particular approximately at the bottom on a vehicle F such as an electric vehicle or plug-in hybrid vehicle. This can be for example about 80 cm by 60 cm in size. The connecting element 4 may preferably be arranged on a lifting device 11, which may be arranged approximately centrally on the floor of a parking lot and in a retracted position or when not in use flush with the ground. By such an arrangement of the contacting plate 2 on the vehicle F on the one hand and the arrangement of the connecting element 4 and the lifting device 11 on the other hand, a simple and automated connection of the connecting element 4 with the contacting plate 2 and a positioning element 3 arranged thereon is possible. The lifting device 11 can be advantageously designed as a robot arm.
    Fig. 10a and 10b show the lifting device 11 with the connecting element 4. The lifting device 11 can be arranged in a floor of a private car park or at the bottom of a public area such as a shopping center, a motorway service area or a taxi stand for loading vehicles F. A connection between the contacting plate 2 and connecting element 4 can always be produced automatically with a loading device 1. It is advantageous if the vehicle F communicates wirelessly with the stationary part of the charging device 1 and the contacting plate 2 has an uniquely assignable identification number.
    It may further be provided that the connecting element 4 is arranged on the lifting device 11, that this is always aligned approximately parallel to the ground. The lifting device 11 may for this purpose comprise an end-side holding device 12, on which the connecting element 4 is arranged, as shown in FIGS. 10a and 10b. The connecting element 4 can also be mounted such that it can move, for example, springs on the end-side holding device 12 in order to be able to perform a lateral or lateral movement in the x-direction and y-direction for latching into one of the positioning elements 3. It can also be provided a mechanism 13 between the end-side holding device 12 and an arm 14 of the lifting device 11, which connects this with the end-side holding device 12 deflectable. Fig. 10a shows the lifting device 11 in a retracted state. This can, for. B. be arranged in a floor of a parking lot and flush with this. For this purpose, the end-side holding device 12 is lowered by the mechanism 13 in comparison to the arm 14, as shown in Fig. 10a. In Fig.10b, the lifting device 11 is shown in an extended state, wherein the end-side holding device 12 is now stretched by the mechanism 12 upwards, in particular in a position which is higher than the arm 14 of the lifting device 11. This takes that on the End-side holding device 12 arranged connecting element 4 a highest position and can subsequently engage in one of the positioning elements 3. For this purpose, it may be advantageous if connection cables are designed to be flexible on the lifting device 11, in order not to influence a position compensation of the connecting element 4. The connection cables can z. B. as fine or feinstdrähtige strands of copper or aluminum and additionally be isolated with a flexible or stretchable material such as rubber or silicone. Further, individual phases can be performed in each case individual lines to increase flexibility again.
    Variants of a positioning of a vehicle F in a parking space are shown in Fig. 11, wherein several possibilities of positioning the vehicle F are shown with a different shading or line. Such a parking space can be 2.3 m wide, for example. It can be provided that the lifting device 11 is arranged with the connecting element 4 approximately centrally on the bottom of such a parking lot. A vehicle F with a contacting plate 2 arranged approximately centrally on the bottom side thereof can be positioned in any position on such a parking space, as can be seen in FIG. 11. It is advantageous if a size of the contacting plate 2 is selected so that the connecting element 4 is always positionable in one of the positioning elements 3 arranged thereon, regardless of how the vehicle F is positioned in the parking lot. With a parking space width of about 2.3 m, the contacting plate 2 can be, for example, about 80 cm by 60 cm.
    When not in use of the contacting plate 2 or without connection of this to the connecting element 4, it is expedient if it is covered by a cover, which protects the contacting plate 2 from dirt or the like. This cover may be formed, for example, foldable, which may be held with at least one magnet in position or a change in position of z. B. a spring is feasible. It can be provided that the contacting plate 2 is automatically and automatically covered as soon as the vehicle F has taken a position for loading. Furthermore, it is expedient if this automatically closes again after completion of a charging cycle. The cover can be constructed of individual flat slats, which may be only a few millimeters thin, for example, about 2 mm to 3 mm. The lamellae can engage with each other with groove and bung and thus form in a closed state a dense and flat unit, with which the entire contacting plate 2 can be covered. The individual slats can z. B. be threaded on rails and move on this. Between each two adjoining slats these can be pushed apart at the point where the groove and bung interlock. This results in an opening in the cover, which exposes part of the contacting plate 2. The maximum movement of the slats on the rail can be limited by a stop at the beginning and end of the rails. In addition, the slats can be compressed by springs, so that the opening is automatically closed. The width of each slat can z. B. half the width of a cell 7 of the contacting plate 2, wherein the lamellae may be at least partially formed of a magnetic material.
    In order to enable an automatic connection of the connecting element 4 with one of the positioning elements 3 of the contacting plate 2, an opening device 15 can be arranged on the lifting device 11, so that the lamellae of the covering device are automated upon contact with the opening device 15 and open at a correct location. A lifting device 11 with the opening device 15 is shown in Fig. 12a. The opening device 15 is advantageously arranged on the lifting device such that the opening device 15 is always arranged approximately parallel to the ground. 12b shows the opening means 15. This comprises in particular two each by 180 ° or three each offset by 120 °, at least one axis movable arms on which at least partially rotatable magnets 16, in particular permanent electromagnets can be arranged. Such magnets 16 are magnetic without energization, with energization, however, an effect of these magnets 16 can be amplified or canceled by reverse current flow. Upon contact of the opening device 15 with the cover of the contacting plate 2, the arms adhere through the magnets 16 to the fins of the cover. Upon application of a compressive force in the direction of the covering device or in the z-direction by the opening device 15, the arms with the lamellae of the covering device are pushed apart in two opposite directions, which are located in the xy plane, without the magnets 16 in x and / or y-direction slip. For this purpose, a surface of the magnets 16 and the fins may be formed accordingly, for example with nubs or grooves. The sliding apart of the arms is shown in Fig. 12c. When pushed apart, the effect of the magnets 16 or their normal and / or adhesive forces can be enhanced by energizing the magnets 16. To close the cover again, the magnets 16 can be solved by reversing the energization again from the slats of the cover. Such an opening device 15 or the entire mechanism for automatically opening and closing a covering device or the like could also be used independently of the loading device 1.
    In a method according to the invention, the connecting element 4 is brought together with the contacting plate 2, as is explained with reference to FIGS. 13a to 13c. The contacting plate 2 is formed so that the connecting element 4 is engaged in a contact with this automatically and yieldingly in one of the positioning elements 3. This is advantageously done independently of a position of the connecting element 4 on the contacting plate 2. In Fig. 13a to 13c three possible positions or cases A, B, C of an impingement of the connecting element 4 on the contacting plate 2 are shown. A first, optimal case A is the direct impingement in one of the positioning elements 3. In this case, no further steps are performed, since the connecting element 4 has already assumed one of the desired end positions. In a second case B, the connecting element 4, which is designed as a cone in FIGS. 13a to 13c, abuts an edge of a hexagonal cell 7, after which it slips off and thus an end position is assumed again. A third case C occurs when the connector 4 is brought to a point where three cells 7 meet. However, the loading device 1 is designed so that the connecting element 4 slips off even when hitting in such a position on the contacting plate 2 in one of the adjacent positioning elements 3. Possible slipping directions of the respective cones are shown by arrows in FIG. 13c. Thus, a discrete position in one of the positioning elements 3 is always assumed by the connecting element 4, regardless of how it impinges on the contacting plate 2. In a method according to the invention, the connecting element 4 is moved orthogonally (in the z direction) to the structure made up of cells 7 as a contacting plate 2 and deflected laterally (in the x and y directions) around a radius of circumference of the cells 7.
    Shown in FIGS. 14a and 14b is a spatially offset three-axis positioning for connecting the connecting element 4 to the contacting plate 2 or a positioning element 3 in comparison to a method according to the invention with a uniaxial positioning. In FIG. 13 a, which represents the prior art, in a first step an actual position and a desired position are detected, for example with a camera or the like. In a second step, a connection is established by at least three-axis positioning. This three-axis positioning is realized, for example, with a robot arm. Such a robot arm is complicated, expensive and expensive to implement. In addition, in the realization of the different arrangement of a positioning element 3 in electric vehicles or plug-in hybrid vehicles from the prior art aggravated added.
    In contrast, FIG. 13b shows a positioning of a connecting element 4 according to the method according to the invention. In this case, the connecting element 4 is connected to an arbitrary point or positioning element 3 on the contacting plate 2. As a result, the movement sequence is reduced to an axis in comparison with that of FIG. 13a, since only one movement in the z direction is necessary for the connection. In addition, no position detection is required.
