Description

[0001] CHARGING DEVICE AND METHOD FOR INSTALLATION

[0002] AREA OF INVENTION

[0003] The present invention relates to a charging device for electric road vehicles and a method for installing a charging device.

[0004] TECHNICAL BACKGROUND

[0005] In the field of charging devices for electric road vehicles, a wide variety of solutions exist for charging the vehicles' traction batteries. These charging devices are available in different forms and designs to meet the diverse needs of users. Particular emphasis is placed on providing a stable and safe energy transfer to the vehicle via charging cables to ensure reliable vehicle operation.

[0006] However, such charging cables, especially those used at high-performance charging stations (HPCs), can be very thick and therefore heavy, as they need to transmit high currents and often incorporate liquid cooling. Various designs exist to improve the user-friendliness of these thick charging cables. In common designs, the charging cables are relatively short, and the charging devices are positioned directly at the parking space in the usual location of a charging port, for example, at the rear left of the vehicle.

[0007] A disadvantage is that for vehicles with a different charging socket position, for example rear right or front left, it is correspondingly difficult to position themselves appropriately at the charging device without obstructing adjacent charging points.

[0008] Charging devices with longer charging cables offer a solution. These cables are mounted on additional, often swiveling or adjustable elements attached to the charging station to facilitate handling and, in particular, to prevent the long cable from dragging on the ground. Due to the reach of the arms and the relatively high weight of the cables, these systems often incorporate substantial mechanical structures and require precise alignment during installation. However, such charging devices are visually bulky and require significant space, dominated by the massive mechanical structures used for cable management. For example, DE 20 2017 100795 Ul describes a long arm that guides a long charging cable but is not foldable.Motorized solutions also exist, as described in DE 10 2022 129 145 B3 or in DE 10 2014 109068 Al, but these require a drive and sensors as well as a solid wall for mounting, which is not possible everywhere and is correspondingly complex to implement.

[0009] In the case of compact solutions with long cables, these are often cumbersome to handle, which puts stress on the bending radii of the charging cables when they are attached and can lead to damage to the internal wires. For example, DE 20 2020 106 059 Ul describes a charging station with a winch that holds the cable taut from above. However, a disadvantage is that when the charging cable is plugged into a vehicle's charging socket from a distance, it is subjected to tension from an angle above, which puts stress on the cable directly at the charging socket, making insertion more difficult. Furthermore, a pull rope is also present in the user's area of ​​operation, which can be problematic, especially in adverse weather conditions and / or in the dark, for users who have poor visibility of these pull ropes.

[0010] SUMMARY OF THE INVENTION

[0011] Against this background, the present invention aims to provide an improved charging device that overcomes these disadvantages and enables a simplified method for installing a charging device.

[0012] According to the invention, this problem is solved by a charging device with the features of claim 1 and / or by a method with the features of claim 15.

[0013] Accordingly, the following is planned:

[0014] - A charging device for electric road vehicles, comprising: a housing having a polygonal base and a recess in an upper edge region; a bearing arranged in or on the recess in the region of a corner; and a boom having a first end and a second end, wherein the first end is pivotably mounted in the edge region by means of the bearing and the second end is connectable to a cable suspension for a charging cable, wherein the boom, in an extended state, is pivotable beyond the housing from the first end to the second end and, in a retracted state, is substantially flush with the housing in the recess.- A method for installing a loading device, in particular a loading device according to one of the preceding claims, comprising the steps of: providing a loading device with a housing having an edge region in which at least two mechanical receiving points are arranged; coupling the receiving points with at least one transport element designed for transporting and / or aligning the loading device; positioning the loading device at a predetermined location, wherein the loading device is transported and / or aligned via at least one transport element; removing the at least one transport element from the receiving points; and coupling a bearing with the receiving points for receiving a boom which is pivotably mounted in the edge region by means of the bearing.

[0015] The underlying idea of ​​the present invention is that the housing of a charging device, which has a polygonal base, has a recess in an upper edge region. The recess is not limited laterally and extends from one corner to another. In particular, the recess extends at least between two corners. This special shape of the housing allows for a flexible, space-saving, safe, and aesthetically pleasing arrangement of a bracket intended for cable suspension within the recess when retracted.

[0016] Another feature is the bearing, which is located in or on the recess in the corner area. This positioning of the bearing allows for a stable yet manually movable mounting, or by manually repositioning the charging cable, while simultaneously allowing the arm to swivel to its maximum extent beyond the housing. The arm itself is designed with a first and a second end. The first end is pivotally mounted at its edge by means of the bearing, while the second end can be connected to a cable holder for a charging cable. This pivoting mounting of the arm offers the advantage that, in an extended position, the arm can swivel from the first end to the second end beyond the housing. The swivel radius extending beyond the housing can advantageously cover essentially the entire length of the arm.The boom can be configured as a two-part, laterally extendable version or as a one-part, frontally extendable version. Three-part or more-part versions are also possible, depending on the boom's dimensions and the opening.

[0017] The arm on the cable suspension can deviate from being flush with the housing. In an advantageous embodiment, this deviation is perpendicular to the housing wall, in order to position the cable far enough away from the housing with minimal material usage, so that the arm remains fully retractable. Increasing the distance to the housing wall can achieve further advantages. For example, it can prevent the cable from striking the housing wall, or it can achieve continuous illumination of the housing wall with control elements located there, thus reducing light pollution.

[0018] Furthermore, according to one embodiment, the boom is automatically retractable to return it to its initial position after use and, in the retracted state, to sit essentially flush with the housing in the recess. In this way, the boom is secured in the recess against unwanted swinging out, e.g., by wind. Automatic retraction is provided between the individual boom sections when multiple sections are used, and also between the boom and frame when a single-piece boom is used. This boom design allows for flexible use of the loading device, as it can be variably adjusted to the height and position of the vehicle being connected, while still remaining manually operable.

[0019] Furthermore, in its retracted state, the boom is essentially flush with the housing and can be received in the recess. According to one embodiment, the recess is designed as a pocket or receptacle within the polygonal base, allowing the boom to be, in particular, completely recessed into it. Thus, in its retracted state, the housing shape or polygonal base is completed or filled by the boom, which is then received or stowed in the recess.

[0020] According to one embodiment, the boom is articulated and has a joint located along its length. In particular, the joint is located centrally along the boom. Preferably, it is a hinge joint. This allows the boom to be folded twice. This advantageously enables particularly compact storage while still maintaining a large reach or span of the boom. In particular, two booms can also be arranged in a common recess on a common side, with the respective bearings located in the opposite upper corners of the housing on this side. The hinges thus meet in the middle of the recess when folded, so that the recess is filled by both booms.The compact and space-saving arrangement according to the invention, when retracted, ensures that the charging device occupies little space even when not in use, has no cavities or protrusions that could collect dirt, and remains visually appealing. Furthermore, the flush fit of the boom within the housing in the retracted state guarantees compactness for minimal space requirements and weather resistance of the construction, for example, during severe weather.

[0021] In this way, a charging device is provided according to the invention which is both safe and user-friendly in handling and yet compact in its dimensions.

[0022] According to the invention, a method for installing a charging device for electric road vehicles is designed to ensure efficient and reliable installation. The invention also guarantees the installation of a stable and functional charging device. At least two mechanical mounting points, preferably three or four, to which the bearing is to be attached, also form the structural basis for the secure and stable mounting of the transport elements that can be inserted into the mounting points. The use of at least one transport element makes it possible to transport the charging device safely and align it precisely. After successful positioning, the at least one transport element is then removed from the mounting points. This ensures that the charging device remains stable in its final location. Finally, the bearing is then coupled to the mounting points.The bearing serves to receive a boom, which is pivotably mounted in the edge region of the housing. This arrangement ultimately enables the safe and user-friendly handling of the boom according to the invention. The method according to the invention thus ensures that the loading device is installed precisely and safely. The method steps are designed to enable simple and clear installation, which simultaneously guarantees the structural integrity and functionality of the loading device.

[0023] Advantageous designs and further developments result from the further sub-claims as well as from the description with reference to the figures in the drawing.

[0024] According to a preferred embodiment of the loading device, the housing has a connection area in which at least two, preferably three or four, mounting points are provided for coupling at least one transport element to the housing. In particular, the mounting points are also designed for coupling the bearing. In this way, after transport, the at least one transport element can be detached and the mounting points used instead for coupling the bearing. The mounting points enable a stable and flexible connection of the bearing to the housing, which guarantees easy installation and secure support of the boom. Furthermore, these mounting points, when coupled with the transport elements, ensure safe transport and reliable installation of the loading device on site. The mounting points are, in particular, at least two mechanical mounting points.Each of these mounting points has a transport element attached for transport purposes. Subsequently, the transport elements are removed from the mounting points, and a bearing is attached to each mounting point to accommodate a boom. For example, the mounting points could each be a threaded hole anchored in the housing, into which either a transport eyelet or a mounting bolt of the bearing can be screwed.

[0025] According to one embodiment of the charging device, the connection area is arranged within the recess. This arrangement offers the advantage that the connection area is protected and at the same time easily accessible, which facilitates the assembly and disassembly of the bearing.

[0026] According to one embodiment of the loading device, the housing has a circumferential frame for mechanically supporting the boom, which is essentially flush with the housing. Alternatively or additionally, the frame is detachably attached to the housing. The frame is thus not merely placed on top of the housing, but integrated within it. In particular, the frame has the shape of the polygonal base at its perimeter and does not extend above the housing. Thus, the frame is securely yet discreetly mounted to the housing, while still being freely configurable in its design and, if necessary, replaceable. For example, the frame configuration can be changed, from a frame with single-piece booms to another frame with multi-piece booms, or the swivel direction, position, or number of booms can be modified, or the like.The surrounding frame does not protrude beyond the housing, or not significantly, and thus essentially sits flush with the housing, which improves the stability and aesthetic integration of the boom into the overall design of the loading device.

[0027] According to one embodiment of the loading device, the bearing is provided in the surrounding frame. In particular, the bearing is either integrated into the surrounding frame or, at least partially, formed integrally with it. This design provides robust and durable support for the boom, thereby increasing the service life of the loading device and minimizing maintenance requirements.

[0028] According to one embodiment of the charging device, the recess is formed around the entire housing, and the frame is received within the recess. This arrangement ensures an even distribution of forces, a compact design, and a harmonious appearance of the charging device that is attractive to customers.

[0029] According to one embodiment of the charging device, the frame has integrated lighting. This lighting improves the visibility of the charging device in poor lighting conditions, thus increasing safety during use. Furthermore, a charging indicator can be implemented in this way, for example, through appropriate color coding of the lighting, such as green for ready to charge and / or blue for in use or not ready to charge.

[0030] According to one embodiment of the charging device, the boom can be manually swung out. The boom and / or the bearing feature, in particular, a return mechanism for the automatic retraction of the boom. The boom thus preferably rests against the housing in the retracted position and is particularly preferably arranged flush with it in at least one direction. Therefore, after manual extension, the boom automatically returns to the retracted position when the charging cable is released. In this position, the boom is securely and aesthetically mounted in a predetermined position, particularly at a stop. This design also avoids cavities and protrusions where dirt could accumulate and minimizes the surface area exposed to the elements. Thus, this construction enables a space-saving, durable, and aesthetically pleasing integration of the boom into the charging device.One advantage of the automatic boom retraction mechanism is that it significantly simplifies the operation of the loading device and increases safety. Users no longer need to manually retract the boom, saving time and improving ease of use. Furthermore, the retraction mechanism ensures automatic retraction, so the boom always rests in a secure position, thus preventing potential damage or accidents.

[0031] According to one embodiment of the charging device, the boom has integrated lighting. Specifically, the integrated lighting is embedded within the boom. The lighting improves the visibility of the boom and facilitates handling, particularly in poor lighting conditions. The integrated lighting also offers the option of displaying the charging status through colored indicators. Especially when multiple charging cables are used, the specific status of each charging point can be displayed directly on the respective cable. Furthermore, the integrated lighting makes it easier to locate and connect the charging cable, for example, in dimly lit environments, thus increasing ease of use. According to one embodiment, the lighting is embedded within the boom, resulting in a slim and attractive design without the need for additional external lighting elements.Because the lighting is integrated into the boom, it is better protected from external influences such as weather and vandalism, thus increasing the charging device's lifespan. According to one embodiment of the charging device, the lighting includes a light element extending at least partially along the boom, designed specifically to project light into the surrounding area. This light element along the boom ensures better visibility of the boom itself, the charging device, and the entire charging area, particularly in poor lighting conditions or darkness. This increases safety for both the user and other road users, and signals the use of the charging point from a distance.The lighting along the boom allows users to more easily identify the position and status of the charging device and park accordingly, making it easier to handle the charging cable and thus improving the user-friendliness of the charging device. By projecting the light into the surrounding area, the area around the charging device is also better illuminated, helping to minimize tripping hazards and other potential dangers in the vicinity.

[0032] According to one embodiment of the charging device, the lighting at the second end of the arm includes a lighting element specifically designed to illuminate a charging cable guided by the cable holder. This lighting element at the second end of the arm provides targeted illumination of the area around the charging cable, facilitating handling and connection, particularly in poor lighting conditions. By specifically illuminating the charging cable guided by the cable holder, the risk of accidents and damage during connection and disconnection is reduced, thus increasing user safety. The targeted illumination of the area around the charging cable also makes it easier to locate and handle the cable and to insert the charging plug into a vehicle's charging socket, making the operation of the charging device more convenient and user-friendly.The lighting enables the charging device to be used without problems even at night or in dark environments, without the need for an additional external light source. The lighting element at the end of the boom can be designed to be weatherproof and bright enough to reliably enable trouble-free use of the charging device even under adverse weather conditions. According to a particularly advantageous embodiment, a white light is integrated into a downward-pointing section of the boom at the second end, such that the light is emitted only downwards. This allows the light to automatically swivel with the second end of the boom towards the connection point, reducing light pollution compared to other lighting arrangements.In another advantageous embodiment, the white light is only activated when the boom is swiveled, and deactivated again after a predetermined standstill time, for example thirty seconds, which further reduces light pollution.

[0033] According to one embodiment of the charging device, the housing includes a ventilation device, in particular for an air conditioning module that can be accommodated inside the housing. Specifically, a gap designed for airflow from the ventilation device and / or a ventilation grille designed for airflow from the ventilation device are provided in or on the recess between the housing and the boom when the boom is retracted. The ventilation device ensures effective cooling of the electronics located inside the housing and, in an advantageous embodiment, effective cooling of a battery module located inside the housing, thus preventing overheating and extending the service life of the electronics and the battery. According to a further embodiment, a battery module that can be accommodated inside the housing and cooled by the ventilation device is also provided.In particular, the battery module can be cooled directly by the airflow from the ventilation system. Alternatively or additionally, indirect cooling of the battery module via the climate control module is possible, which in turn can be cooled by the airflow. Cooling the electronics and the battery increases their performance and improves the overall efficiency of the charging device, resulting in shorter charging times and greater reliability. By preventing overheating and thus protecting the electronics, battery, and other components, the ventilation system contributes to the improved longevity and sustainability of the charging device. An appropriately designed arm spacing and / or a suitable ventilation grille can optimize the airflow and thus reduce the noise level of the ventilation system, resulting in quieter operation of the charging device.The advantages of avoiding open cavities and protrusions can be preserved in an advantageous embodiment by attaching a form-fitting ventilation grille to the housing that covers the gap of the boom. In another advantageous embodiment, the ventilation grille is attached to the boom or to a surrounding frame. In a modified embodiment, the ventilation grille is convex upwards and otherwise form-fitting.

[0034] According to one embodiment of the loading device, the housing includes a housing end on a side facing away from the boom. A display device can be placed on the housing end, which can be designed, for example, as a housing wall or housing door. Such a display device extends beyond the housing and / or the recess. That is, it is modular and mounted externally on the housing. Because the display device is located on a side facing away from the boom, the boom remains flush with the housing. For example, the boom is located on a front side of the loading device and the display device on a side. The placement of the display device on the housing end allows for easy and convenient reading of information, as it extends beyond the housing and / or the recess.This improves the visibility of the displayed information, especially in areas with limited visibility. The display device is particularly suitable as a flexible information or advertising space. Positioning the display device on the far side of the boom makes efficient use of the available space and allows it to be used for other purposes besides displaying charging information, such as advertising, instructions, or traffic information, without interfering with the charging device's primary functions.

[0035] According to one embodiment, a method for installing the loading device provides three or four mounting points for coupling the bearing, and at least one transport element is attached to these three or four mounting points, and / or a circumferential frame designed to mechanically support the boom is attached to the mounting points. The use of three or four mounting points for securing the bearing ensures an even distribution of the load and increases the stability of the loading device. Attaching transport elements to multiple mounting points facilitates the transport and positioning of the loading device, as the weight is better distributed and handling is simplified.

[0036] According to one embodiment, a circumferential frame designed to mechanically support the boom is attached to the mounting points in a method for installing the loading device. This circumferential frame provides additional mechanical support for the boom, increasing its robustness and service life. The option of attaching a circumferential frame to the mounting points facilitates a modular design of the loading device, simplifying repairs and upgrades. The frame allows the bearing(s) and boom(s) to be pre-assembled and attached to the housing in a modular fashion. This requires only the frame to be attached to the mounting points. In an advantageous refinement of this embodiment, a gap is left between the circumferential frame and the housing to ensure adequate ventilation of the housing.In a further advantageous refinement, the gap between the surrounding frame and the housing is covered by a form-fitting ventilation grille to prevent the formation of an open cavity that could collect and retain dirt. In a modified embodiment, the ventilation grille is convex.

[0037] According to another embodiment, a gap is left between the boom and the housing in a method for installing the loading device, which is large enough to ensure ventilation of the housing. In an advantageous embodiment, a ventilation grille is attached to the boom, which, when retracted, precisely covers the gap between the boom and the housing. This advantageously prevents the formation of an open cavity that could collect and retain dirt, while simultaneously ensuring ventilation of the housing even when the boom is retracted. In a modified embodiment, the ventilation grille is convex.

[0038] The above embodiments and further developments can be combined with one another as appropriate. Further possible embodiments, further developments, and implementations of the invention also include combinations of features of the invention described previously or subsequently with regard to the exemplary embodiments, even if not explicitly mentioned. In particular, the person skilled in the art will also add individual aspects as improvements or additions to the respective basic form of the present invention.

[0052] DESCRIPTION OF EXAMPLES OF EXECUTION Fig. 1 shows a schematic representation of a charging device 1 for electric road vehicles according to an exemplary embodiment.

[0053] The charging device 1 has a housing 2 with a polygonal base. A recess 7 is provided in an upper edge region RB of the housing. A bearing 3 is arranged in or on the recess 7 in the region of one corner. A first end of a boom 4 is pivotally mounted on the bearing. The second end 4b of the boom is designed to be connected to a cable suspension 5 for a charging cable.

[0054] The boom 4, in its extended position (shown here with dashed lines), can be swung out beyond the housing 2 from its first end 4a to its second end 4b. In its retracted position (shown with solid lines), the boom is essentially flush with the housing 2 and can be received in the recess 7.

[0055] Essentially flush means that the majority of the surface is flush, but a smaller portion may protrude, in particular the second end may be provided with an angle or a bend to couple the cable suspension 5.

[0056] Fig. 2 shows a schematic representation of a charging device according to an exemplary embodiment.

[0057] The figure shows a charging device 1 for electric road vehicles, also comprising a housing 2, which has an upper edge region RB and two recesses 7. Within each of the two recesses 7, a bearing 3 is arranged in or on the respective recess 7, in the region of one corner. A cantilever 4 is mounted in the bearing 3 at its first end 4a and is pivotably mounted in the edge region RB by means of the bearing 3. In contrast to Figure 1, this is a two-part cantilever, the two parts of which each form an end and are articulated, for example by a hinge 20.

[0058] At the second end 4b, each arm 4 can be connected to a cable suspension 5 for a charging cable. Here too, in an extended state, each arm 4 can be pivoted beyond the housing 2 from the first end 4a to the second end 4b, and in a retracted state, it can be received in the recess 7 essentially flush with the housing 2. "Essentially flush" here means that the majority of the arm is flush with the housing, but the second end is provided with an angle or bend to connect to a cable suspension 5 located in front of the housing (see Fig. 3).

[0059] Fig. 3 shows a schematic representation of a charging device according to an exemplary embodiment.

[0060] The illustration shows a front view of the integration of two arms 4 within a common recess 7. Here too, they are flush with the housing 2 of the charging device 1. An integral component of the arms 4 is a light 9, provided by a longitudinally embedded light element 9a.

[0061] Additionally, a cable suspension 5 attached to the second end 4b of the boom 4 and a lighting element 9b provided at the second end 4b are shown. In the present embodiment, the housing 2 includes a housing end cap 12 on the side facing away from a boom 4, here the transverse side. An optional display device 13, symbolized by the dashed line, can be placed on the housing end cap, projecting beyond the housing 2 and the recess 7.

[0062] Concealed by the housing 2 is an air conditioning module that can be accommodated inside the charging device 1, which is also symbolized by a dashed line.

[0063] Fig. 4 shows a schematic top view of a loading device 1 according to a further embodiment.

[0064] Shown here is also a two-part version of the boom 4, which, in an extended state, can be swung out beyond the housing 2 from the first end 4a to the second end 4b, and, in a retracted state, is essentially flush with the housing 2 and can be received in a bearing 3 in the recess 7. A circumferential frame 8, received in the recess 7, supports the boom 4.

[0065] The two-part boom 4 is articulated and has a joint 20 located centrally along its length. This allows the boom to fold in two places.

[0066] Preferably, the joint 20 is a hinge joint that allows rotation in only one degree of freedom, for example about the vertical axis. Thus, the boom advantageously remains in the horizontal plane of the recess 7 at all times. However, multidimensional joints would also be conceivable in other embodiments. A connection area AB with at least two mounting points 6, preferably three or four mounting points 6, is provided on the housing of the loading device 1.

[0067] The charging device 1, as shown in Fig. 4, further comprises a ventilation device 10, which serves, for example, for an air conditioning module 11 for cooling internal components, such as charging electronics and / or a battery module 19 that can be accommodated inside the housing 2.

[0068] Additionally, an optional display device 13, marked by the dashed line, is placed on a housing end 12 on the side facing away from the boom 4, and extends beyond the housing 2 and the recess 7.

[0069] Fig. 5 shows a flowchart of a procedure for installing a charging device.

[0070] The process steps S1 to S3 are shown. Process step S1 involves providing a loading device 1 with a housing 2, process step S2 involves coupling the receiving points 6 with at least one transport element 17, and process step S3 involves positioning the loading device 1 at a predetermined location. A detailed description of process steps S1 to S3 follows with reference to Figures 6A to 60.

[0071] Figures 6A to 6C show schematic views of the process steps S1 to S3 according to Figure 4 for installing a charging device.

[0072] Fig. 6A shows a schematic view of the process step S1 according to Fig. 5 for installing a loading device 1, wherein a loading device 1 is provided with a housing 2 which has an edge area RB in which at least two mechanical receiving points 6 are arranged in which at least two transport elements 17 are coupled.

[0073] Fig. 6B shows a schematic view of process step S2 according to Fig. 5 for installing a loading device 1, wherein the receiving points 6 are coupled with at least one transport element 17 to transport and align the loading device 1 at a predetermined location. A crane, symbolized here, can be used for this purpose.

[0074] Fig. 6C shows a schematic view of process step S3 according to Fig. 5 for installing a loading device 1, wherein the latter is positioned at a predetermined location and the loading device 1 is transported and / or aligned via at least one transport element 17.

[0075] For illustrative purposes only, the positioning of the charging device 1 is shown here on an interface unit 14 fixed to a floor as a predetermined location.

[0076] This is followed by the removal, not shown in detail here, of at least one transport element 17 from the mounting points 6, the reverse of Fig. 6A. The view also shows the coupling of a bearing 3 with the mounting points 6 for receiving a boom.

[0077] As an example, a circumferential frame 8 is coupled via the at least two mounting points 6 with fastening means, in which the bearing 3 is integrated for receiving a boom 4, which is pivotably mounted in the edge region RB by means of the bearing 3. Fig. 7 shows a side detail view of a ventilation device 10 of a loading device 1.

[0078] The illustration shows a ventilation device 10 and a ventilation grille 16 of a loading device 1. In the recess 7, in the retracted state of the boom 4, a gap 15 designed for an airflow of the ventilation device 10 and a ventilation grille 16 designed for an airflow of the ventilation device 10 are provided between the housing 2 and the boom 4.

[0079] A light element 9a is also mounted longitudinally in the surrounding frame 8. Additionally, display devices 13 are attached to both transverse sides of the charging device 1.

[0080] Fig. 8 shows another side view of a ventilation device 10 of a loading device 1 .

[0081] The illustration shows a side view of the boom 4 mounted in frame 8 and a cable suspension 5 of the loading device 1. A lighting element 9b is installed in an angled section of the second end, which connects the cable suspension 5 to the boom 4. The ventilation device 10, the ventilation grille 16, and the gaps 15 are designed such that, in or on the recess 7, when the boom 4 is retracted, a gap 15 designed for an airflow from the ventilation device 10 and / or a ventilation grille 16 designed for an airflow from the ventilation device 10 are provided between the housing 2 and the boom 4.

[0082] Fig. 9 shows a front view of a charging device according to an exemplary embodiment. As in Fig. 3, the two arms 4 in their two-part version with their respective cable suspensions 5 are shown. Also shown is the housing 2 of the charging device 1 with an integrated air conditioning module 11, designed for cooling electronic components or an integrated battery module 19.
