[0001] DESCRIPTION

[0002] Curbside or kerbside charging device for charging an energy storage device of an electrically powered vehicle

[0003] The invention relates to a curb or kerb charging device for charging an energy storage device of an electrically driven vehicle, comprising a base element made of concrete, natural stone or plastic and having a recess, a receiving container arranged in the recess in the base element and delimited by a floor, two longitudinal walls and two short transverse walls and forming a curb element with the base element, and a charging unit arranged in the receiving container.

[0004] Such curbside charging devices are charging stations integrated into the curb, to which vehicles can be connected via an electrical connection to charge their energy storage units or batteries. This particularly applies to purely electric vehicles, but also to hybrid vehicles. Chargeable vehicles can be passenger cars, trucks, motorcycles, or electric bicycles.

[0005] Due to the new legislation, the growing interest of the population in climate protection and the improved economic viability of electrified vehicles, it is to be expected that the proportion of electric vehicles will increase dramatically, especially in inner-city areas, so that the available charging infrastructure must be expanded significantly. This means that some of the existing parking spaces must be provided with appropriate charging options in order to ensure individual mobility in the future.

[0006] Known concepts for this include the use of streetlights, additional charging stations, or wall boxes on building walls. All of these concepts require additional space and cause disruption to pedestrians due to the charging cables required.

[0007] For this reason, charging systems have become popular where the charging devices are integrated into the curb or kerb. This has the advantage that no charging stations obstruct the sidewalks and thus spoil the visual appearance. Instead, no additional space is required, simply utilizing existing infrastructure. Modularization allows for high flexibility and retrofit capability. Damage to the charging infrastructure caused by vehicle accidents can also be prevented.

[0008] Accordingly, DE 10 2017 218 947 A1 proposes installing a charging device for charging vehicles in the curb of a road. The curb is either designed with a power supply or has its own energy storage unit.

[0009] A special design of such a curb with electronics for charging a vehicle is known from GB 2 592 186 A. This curb has a modular design and comprises a base element into which a replaceable receptacle can be inserted. This receptacle is therefore not fixed. The components for electrically charging a vehicle's battery are arranged in this receptacle. The receptacle is open at the top and is closed by a lid, which borders the base element towards the street with a sloping wall. The base element, as well as the receptacle and lid, are made of plastic.

[0010] The problem with such a curb is that it lacks sufficient durability, as the lid and container are pushed against the base element when a vehicle tire hits the curb. This initially places stress on the container and lid, and then suddenly transfers this stress to the base element. Such a curb cannot adequately absorb the resulting tensile forces.

[0011] The task therefore arises of providing a curb or kerb charging device for charging an energy storage device of an electrically powered vehicle. This device must be extremely durable and thus suitable for large-scale use as a curb in cities, as well as in parking lots or motorway service areas, without the need for constant maintenance or frequent replacement. This must protect the electronics in the container from damage, while also maintaining the curb's function as a road barrier, preventing damage to the curb and, consequently, damage to the car tires from pieces of the curb breaking off. Furthermore, the device must be as flexible as possible, and installation must be as simple and error-free as possible.

[0012] This object is achieved by a curb or kerb charging device for charging an energy storage device of an electrically powered vehicle with the features of main claim 1. A curb or kerb charging device according to the invention for charging an energy storage device of an electrically powered vehicle has a base element which is made from concrete, natural stone, plastic or composite material, for example by casting. This base element has a recess in which a receiving container is received. This receiving container has a base, two longitudinal walls and two short transverse walls by which it is delimited. Here, a longitudinal wall is understood to be a wall that extends parallel to the road, while a transverse wall is a wall that delimits the receiving container perpendicular to the longitudinal wall and parallel to the adjacent ends of the curbs.The base element, together with the receptacle, forms a curb element that can be used to mark the boundary of a road, a parking lot, or the like. A charging unit is arranged in the receptacle, which can include various electronic components that can be used to charge the energy storage device of the electric or hybrid vehicle. According to the invention, the receptacle rests laterally against a side wall of the base element over its entire length, at least with one of its longitudinal extension walls. A lid made of metal or fiber-reinforced plastic covers an open side of the receptacle and additionally extends over an upper side of the side wall of the base element that is adjacent to the open side of the receptacle and, when installed, points upwards, against which the longitudinal extension wall of the receptacle rests.This surrounding support of the lid allows loads, such as those caused by vehicle tires, to be absorbed and evenly distributed into the curb. This creates a high level of rigidity for the curb loading device, as even forces introduced over small areas are always distributed within the curb via the receiving container and the adhesive surfaces, thus dissipating them across the entire curb.

[0013] The receiving container is preferably made of steel, especially stainless steel, and therefore offers very high stability and strength. This allows forces to be dissipated across a large area to the base element via the walls and floor.

[0014] Furthermore, it is advantageous if the lid is made of steel, especially stainless steel. This prevents deformation or damage to the lid and simultaneously ensures that any impact force can be dissipated into the curb across the entire contact surface of the lid.

[0015] It is particularly preferred if the receiving container is secured to the base element, especially over a large area. Such a fastening prevents relative movements of the receiving container to the base element, which could cause pressure surges on small areas. Accordingly, the durability of the curb or kerb loading device is improved.

[0016] In a further embodiment, the receptacle is attached to the base element by adhesive bonding. In particular, this bonding is carried out over a large area, covering the adjacent transverse and longitudinal walls, as well as the floor. This ensures a large-area contact and widespread distribution of any forces that occur, which also improves strength.

[0017] Furthermore, the receptacle can be additionally secured to the base element using screws. These additional screw connections for the receptacle can be provided in the base element, for example, using cast-in threaded sleeves, which can be anchored in the side wall, the floor, or the cross walls.

[0018] Preferably, the lid completely covers an edge formed in the installed state between the upper side and a side surface of the curb element facing the road, at least along the longitudinal extent of the receiving container, thereby protecting the sensitive edge at which an impact of a vehicle tire is to be expected.

[0019] It is particularly preferred if the cover has a rounded impact wall which, when installed, covers the kerb element at the transition between the top of the kerb element and the side surface of the kerb element facing the road. This rounded shape prevents damage to the vehicle tire. Furthermore, due to the arrangement of the cover's impact wall in the transition area between the top and the side surface of the kerb facing the road, an initial contact is always safely absorbed by the cover and diverted over a correspondingly large area, regardless of the vehicle size and thus the tire size, regardless of whether it comes from the side or from above.

[0020] In an advantageous embodiment of the invention, the base element has a base on which the receptacle rests, and the side wall of the base element, against which the longitudinal wall of the receptacle rests, faces the street side, with the impact wall of the lid resting on this side wall of the base element. Thus, the side surface continues to be formed by the concrete or plastic of the base element, which has proven itself as an outer curb surface for many years. However, the wall surface, which is now significantly thinner due to the receptacle, is reinforced by the design of the lid and the connection of the rigid receptacle. The durability and strength of the side surface facing the street are thus maintained.

[0021] Furthermore, it is advantageous if the base element has a transverse wall at each of its two ends, which delimits the curb element from adjacent curb elements and against which the short transverse walls of the receptacle and the lid rest, wherein the curb element is delimited on its side facing away from the street in the installed state by a longitudinal wall of the receptacle. This means that the wall facing the street can be made thicker and yet plenty of space can be provided to accommodate the receptacle. The transverse walls also divert forces within the base element and significantly increase the stability of the base element. The transition between the transverse walls of the base element and the lid is designed to be as continuous as possible, in particular rounded, so that no cracks or edges are created.

[0022] An additional increase in strength and durability of the base element is achieved by making the base element from a fiber-reinforced plastic or fiber-reinforced concrete.

[0023] Furthermore, the lid is advantageously attached to the receptacle with screws. This reliably prevents any relative movement of the lid to the receptacle and thus also to the base element. Furthermore, the electronics in the receptacle can be easily replaced. In a further embodiment, the transverse walls in the upper area have internal threads into which the screws for securing the lid are screwed. This allows for easy tightening of the lid.

[0024] The screws are preferably security screws or tamper-proof screws that can only be removed with special tools and may provide protection against electric shocks or theft.

[0025] Furthermore, it is possible for the lid to be attached to the receiving container and the base element with screws. This creates an additional, rigid connection between the lid and the base element, eliminating relative movement and ensuring that any force is always distributed across the entire curb or kerb loading device.

[0026] The receptacle preferably has a flange-like extension or constriction at an upper edge of the transverse walls, in which the internal threads are formed. This allows the walls of the receptacle to be made thin, yet still allows for a simple, force-fit connection between the receptacle and the lid.

[0027] It is also advantageous if the longitudinal and transverse walls of the receptacle are wider at their upper edge than in the area adjacent to them below, and if a circumferential groove is formed at the upper edge, in which a circumferential seal is arranged, against which the lid rests. This allows for a tight closure of the receptacle despite the thin walls and the resulting low weight and reduced material requirements. Accordingly, the electronics are protected from water ingress.

[0028] Preferably, the receptacle has an outwardly projecting extension on its longitudinal wall, which bears against the side wall of the base element. This extension rests on the upper side of the side wall of the base element and extends laterally to the section of the rounded impact wall of the lid facing the road, which wall rests adjacent to the extension on the upper side of the side wall of the base element. This design ensures that, when the tire impacts the curb, the load from the lid is transferred directly into the receptacle and the base element, thus effectively distributing the resulting forces. In particular, this prevents the base element from being loaded at a small force application area.

[0029] Furthermore, it is advantageous if an elastomer layer is arranged between the lid and the receiving container and / or the upper side of the side wall of the base element. This ensures a more even distribution of the applied forces to the boundary walls of the receiving container and the side wall of the base element when the lid deflects.

[0030] In a particularly preferred embodiment of the invention, the receptacle has a plug receptacle area, an electronics receptacle area, and an electrical connection area. Such a division facilitates access when connecting the curbside or kerbside charging device to the underground cable and thus to the power supply, since access is not blocked by other electronic components. Access to the connector socket is also provided separately. Accordingly, a completely modular curbside or kerbside charging device is created.

[0031] Advantageously, a connector socket and a lifting, folding, or pivoting mechanism are arranged in the connector receptacle area, via which the connector socket can be guided out of the receptacle and through an opening in the lid. The connector socket is connected to a contactor switched via a charging controller, which is arranged in the electronics receptacle area. This creates space for the lifting, folding, or pivoting mechanism of the connector socket that is not further restricted by the electronics. Only the cable is led out of the connector receptacle area into the electronics receptacle area for the charging controller. This arrangement enables a trouble-free connection of the connector socket and facilitates any necessary replacement.

[0032] Furthermore, it is advantageous if an opening is formed at the bottom of the receptacle, which is an extension of an opening in the bottom of the base element and through which a power supply cable protrudes into the electrical connection area. This opening can be used for drainage but, above all, for connecting the electronics to the power supply network. With this arrangement, the connection is very easily accessible, thus facilitating assembly.

[0033] To further facilitate this connection, a contact terminal is located in the electrical connection area. This contact terminal can be connected to the power supply cable and is electrically connected to the electronic components in the electronics receptacle area. When installing the curbstone on the street, only the power supply cable needs to be attached in the connection area, specifically to the connector socket or terminal, while the remaining connections can be delivered pre-assembled.

[0034] Preferably, a contactor, a residual current device and / or a miniature circuit breaker, a power supply, an energy meter, and an RFID board are located in the electronics housing area. The contactor can be a standard contactor or a power contactor. This prevents damage to the vehicle caused by errors in the curbside or kerbside charging device, and provides everything needed to charge the vehicle's battery, obtain approval for charging, and measure the amount of current charged.

[0035] Furthermore, a residual current sensor is arranged in the electronics housing area, which serves to detect smooth DC residual currents.

[0036] In addition, it is preferred that the lid has a viewing window or a viewing opening which is formed directly above a display of the energy meter, so that the user always has an overview of the amount of energy supplied.

[0037] In an alternative design, the energy meter is connected to a display, which is located below the viewing window or directly in a viewing opening in the cover, or can be retracted and extended using a lifting, folding, or pivoting mechanism. This allows the display to be positioned independently of the energy meter's location.

[0038] This creates a curb or kerb charging device for charging an energy storage device of an electrically powered vehicle. The device is highly rigid and durable, thus preventing damage to the curbs and kerbs while simultaneously protecting the electronics. Furthermore, the curb or kerb charging devices according to the invention are flexible and modular in design, yet very easy to install. The excavation work required for assembly is minimized, as is the number of assembly steps required to implement a system that can be used, for example, to build a smart city with networks, charging stations, and counting and measurement systems. The cityscape is not altered. Loss of space is avoided, as are tripping hazards caused by cables on the sidewalks. The number of required energy sources can also be reduced.

[0039] Two non-limiting embodiments of curb or kerb charging devices according to the invention for charging an energy storage device of an electrically powered vehicle are described below.

[0040] Figure 1 shows a schematic diagram of a road with a limiting curb or kerb loading device in plan view.

[0041] Figure 2 shows a perspective view of a curb or kerb loading device according to the invention.

[0042] Figure 3 shows a longitudinal section through a curb or kerb loading device according to the invention in a perspective view.

[0043] Figure 4 shows a perspective cross-section of a first embodiment of a curb or kerb charging device according to the invention without electronics. Figure 5 shows a perspective cross-section of a second embodiment of a curb or kerb charging device according to the invention without electronics.

[0044] Figure 1 shows a sidewalk 10, which is bordered on one side by a house wall 12 and on the other side by a curb 14 formed by several stone elements 16 and a curb or kerb charging device 18 according to the invention, forming a boundary to the street 19. On the side of the sidewalk 10 facing away from the curb 14, there is an energy source 20 in the form of a power connection connected to the power grid. The energy source 20 is connected to the curb or kerb charging devices 18 via underground power supply cables 22. Connector sockets 24 are arranged on the curb or kerb charging devices 18, into which a plug 26 is inserted. The plug 26 is connected via a cable 28 to an energy storage device 30, in particular a battery of an electrically powered vehicle 32, so that this energy storage device 30 can be charged via the energy source 20.

[0045] A curb loading device 18 according to the invention is shown in Figure 2. In the following, the terms "top," "bottom," "below," "above," or similar refer to the state of the curb loading device 18 that corresponds to the state installed at the roadside. A "top" thus corresponds to the side facing away from the ground surface in the installed state.

[0046] The curb loading device 18 according to Figure 2 consists of a base element 34, which is made of concrete or plastic and may contain fiber reinforcements. This base element 34 has a base 36, from which a total of two transverse walls 38 and a side wall 40 extend upwards. The transverse walls 38 are located at the two ends of the curb loading device 18, viewed in the longitudinal direction, so that adjacent curb loading devices 18 abut one another with these transverse walls 38. The side wall 40 delimits the curb loading device 18 from the street.

[0047] Behind this side wall 40 and between the two transverse walls 38, a recess 42 is formed on the base element 34, into which a receiving container 44, in particular made of steel, is glued. The bonding can be carried out, for example, using an epoxy resin and is carried out as fully as possible over a base 46 of the receiving container 44 as well as a first longitudinal wall 48 directed towards the side wall 40 and two transverse walls 50 of the receiving container 44, which then bear firmly against the base 36, the side wall 40, and the transverse walls 38 of the base element 34.

[0048] The receiving container 44 also has a second longitudinal wall 52, which extends in extension of the ends of the transverse walls 38 and the floor 36 of the base element 34 facing the sidewalk 10 and thus faces the sidewalk 10. The receiving container forms a curb element 54 with the base element.

[0049] A lid 56, which is made in particular of steel, is attached to the curb element 54 and closes an upwardly facing open side 58 of the receptacle 44. In addition, the lid 56 also rests on an upper side 60 of the side wall 40 of the base element 34 and, viewed in the longitudinal direction, also extends over the ends of the receptacle 44. The lid 56 has a rounded impact wall 62, which covers an edge 63 between the upper side 60 of the side wall 40 and a street-facing side surface 64 of the side wall 40. This rounded impact wall 62 extends an impact edge 66 between upper sides 68 of the transverse walls 38 and their street-facing side surfaces 70.

[0050] The cover 56 is secured by means of two screws 72 which, viewed in the longitudinal direction, extend at the ends of the cover 56 through corresponding holes 74 in the cover 56. The screws 72 are screwed into an internal thread 76 of a flange-like extension 78 extending on both sides to the transverse walls 38 of the base element 34 and extending from an upper edge 80 of the receiving container 44.

[0051] In order to accommodate these flange-like extensions 78 and the screws 72, receiving openings 82 are formed centrally on the regions of the transverse walls 38 opposite the transverse walls 50 of the receiving container 44, into which the screws 72 and the flange-like extensions 78 protrude. These receiving openings 82 can also be filled with the adhesive, in particular the epoxy resin, whereby the screws 72 and the cover 56 are also at least indirectly fixed to the base element 34. Longer screws 72 and deeper recess openings 82 can also be provided, so that the ends of the screws are fastened directly in the base element, if necessary via an adhesive.

[0052] Figure 4 shows that the receiving container 44 is wider at its upper edge 80 than in the adjoining lower region. For this purpose, the walls 50, 52 are widened inwardly at their upper edge 80, so that a circumferential groove 84 can be formed at the upper edge 80, in which a seal 86 is arranged, by which the receiving container 44 is tightly closed when the lid 56 is placed in place.

[0053] An alternative embodiment of the receiving container 44 is shown in Figure 5. It has, on its longitudinal wall 48 facing the side wall 40 of the base element 34, an outwardly projecting extension 88 extending from the upper edge 80, which rests on the upper side 60 of the side wall 40 of the base element 34 and extends to the impact wall 62 of the lid 56. An elastomer layer 90 between the receiving container 44 and the lid 56 seals the interior of the receiving container 44 and distributes the forces introduced into the upper side 60 of the side wall 40 over a wider area when the lid deflects.

[0054] As can be seen in Figure 2, the cover 56 has an opening 92 and a viewing window 94. Below this opening 92 is the connector socket 24, which is arranged in a connector receiving area 98 in the receptacle 44. This connector socket 24 is, as shown in Figures 2 and 3, closed by a connector cover 96 and can additionally be provided with a lifting or pivoting mechanism 100 (shown only schematically), via which the connector socket 24 can be extended beyond the cover plane.

[0055] The connector socket 24, like an energy meter 102, whose display 103 is arranged below the viewing window 94 to allow the user to read the amount of current charged, is part of a charging unit 104 arranged in the receptacle 44. For this purpose, overlapping openings 106, 108 are formed on the bottom 46 of the receptacle 44 and on the bottom 36 of the base element 34, through which the power supply cable 22 can be pulled from below through the base element 34 into the receptacle 44. The power supply cable 22 is connected in an electrical connection area 110 of the receptacle to a contact terminal 112, which can be designed as a terminal or connector socket depending on the power supply cable 22 used.The further power supply cables 22 and connecting cables, which are not shown in Figure 3 for the sake of clarity, lead from the contact connection 112 into an electronics receiving area 114 in which further electronic components 116 are arranged.

[0056] These electronic components 116 include, in addition to the energy meter 102 already mentioned, a charging controller 118, a contactor 120, in particular a high-voltage contactor, a residual current device and / or circuit breaker 122, a power supply unit 124 connected to the charging controller 118, a residual current sensor 126, in particular a DC fault sensor, and an R.FID board 128, via which the user can be identified.

[0057] A curb loading device constructed in this way hardly changes the streetscape and can be installed even in narrow cities with almost no additional space required. Despite its small size, it is very durable, as forces from vehicle wheel impacts are absorbed by the impact edge or the steel lid and can be evenly distributed across the receiving container and the base element. The side walls and cross walls of the base element can be designed sufficiently wide to prevent them from breaking out when forces are absorbed. Instead, a large portion of the force can be absorbed by the very stable lid and very stable receiving container and transferred to the base element across a large area. This results in very good durability and strength.Nevertheless, the curbside charging device has a modular design, allowing for customization of the electronic components. These components can also be easily replaced thanks to their easy accessibility.

[0058] It becomes clear that with the described curbside charging devices for charging an energy storage device of an electrically powered vehicle, a complete charging infrastructure can be created in a simple way, which is flexible and modular in design and yet very easy to install.

[0059] Furthermore, it should be clear that the electronics can be adapted to the respective conditions, especially the legal requirements of the respective countries. The connector socket can be equipped with a wide variety of lifting, folding, or pivoting mechanisms. The cover can also be attached in different ways.
