[0001] DESCRIPTION

[0002] Curb, paving stone or kerb charging device for charging an energy storage device of an electrically powered vehicle

[0003] The invention relates to a curb, paving stone or kerb charging device for charging an energy storage device of an electrically driven vehicle, comprising a curb, paving stone or kerb element which has a receiving space in the interior and which, when installed, has a boundary wall which is exposed to the outside and the environment, and a charging unit which is arranged on the curb, paving stone or kerb element and which has electronic components arranged in the receiving space and an interface for energy transmission to the energy storage device of the vehicle and one or more transmitting and receiving units.

[0004] Such curb, paving, or curb charging devices are charging stations integrated into the curb, paving, or 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 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] In order to create a communication option for such a curb, paving stone or kerb charging device with which data can be exchanged between the user and a server of the operator of the charging system, it is known to use radio antennas.

[0009] For example, GB 2 591 830 A proposes a curb, paving stone, or kerb charging device featuring a replaceable head made of plastic and containing a transmitting and receiving unit in the form of a mobile phone antenna. However, the use of plastics is problematic because, although they are generally permeable to radio waves, they lack sufficient mechanical durability.

[0010] The task therefore arises to provide a curb, paving stone or kerb charging device for charging an energy storage device of an electrically powered vehicle, which enables the most undisturbed transmission of radio signals while at the same time ensuring good durability of the curb, kerb or paving stone unit.

[0011] This object is achieved by a curb, paving stone or kerb charging device for charging an energy storage device of an electrically powered vehicle having the features of main claim 1.

[0012] The curb, paving stone, or kerb charging device according to the invention for charging an energy storage device of an electrically powered vehicle consists of a curb, paving stone, or kerb element and a charging unit. A receiving space is formed in the curb, paving stone, or kerb element, which accommodates at least parts of the charging unit. The receiving space is delimited by several boundary walls, of whose outward-facing surfaces, for example in the case of a built-in curb, at least two, namely the front surface facing the street and the upward-facing surface, are exposed. Exposed in this case means that the corresponding surface of the boundary wall facing outwards towards the surroundings is not concealed by other elements.Accordingly, the curbstone, paving stone or kerbstone element, when installed, has at least one boundary wall exposed to the outside environment.

[0013] The charging unit located in the receiving space has electronic

[0014] Components and an interface for energy transfer to the vehicle's energy storage system. The electronic components can include the complete charging control system, including energy meters, contactors, circuit breakers, power supply, current transformer, charging control unit, and motor control, or individual components thereof. The interface for energy transfer can be a charging socket, an extendable charging cable, or an inductive interface. Furthermore, the charging unit has at least one transmitting and receiving unit, which can be a mobile radio antenna, Bluetooth, WLAN, and / or an RFID antenna. The user is either connected to the backend via their mobile device, and the backend is connected to the charging device via the Internet, or the user is identified directly by the charging unit via RFID, which in turn is connected to the backend via the Internet for status display and billing.The transmitting and receiving unit establishes communication between the user, an operator server, and the curbside, paving, or kerbside charging device, allowing the charging process to be started and stopped remotely, and energy meter data to be transmitted to the user. Authentication via an app, maintenance, or the installation of software updates can also be performed.

[0015] According to the invention, the boundary wall is made of a radio wave-absorbing material, in particular of metal, a plastic containing carbon fibers, or similar materials that are electrically conductive but have very high strength. At least one recess is formed on the boundary wall, which is tightly closed to the outside environment by a non-metallic cover. The non-metallic cover is accordingly made of a radio wave-non-absorbing material, in particular of a plastic, glass, or ceramic, and completely seals the recess. The transmitting and receiving unit is arranged at least partially within a projection surface, which is formed by a projection of the surroundings of the curb, paving stone, or kerb element perpendicularly onto the wall surface of the cover that is exposed to the environment.This means that the transmitting and receiving unit is located on the side of the cover opposite the surroundings, so that radio waves can penetrate through the cover to the outside with as little interference as possible, ensuring communication between the user and thus the charging control and the operator's server despite the use of a high-strength boundary wall.

[0016] The transmitting and receiving unit is preferably a 2G, 3G, 4G, 5G, 6G, WLAN, RFID or Bluetooth antenna, so that both authentication and the general and fast transmission of data in both directions can be ensured, allowing remote control, maintenance and / or diagnostics to be carried out and, for example, software updates to be installed.

[0017] The recess is preferably formed on a surface of the boundary wall facing the environment, and the boundary wall to the receiving space is essentially closed in the region of the recess, with the transmitting and receiving unit being arranged in a space between the boundary wall and the cover. The transmitting and receiving unit then rests, in particular with the interposition of a layer of a material that does not absorb radio waves, on the boundary wall closing the receiving space in the region of the recess, so that the surface of the boundary wall facing the environment is covered by the cover in the region of the recess. Essentially closed means that a cable for charging control can be led through the boundary wall, whereas otherwise the boundary wall is closed in the region of this recess to the receiving space.This allows the transmitter and receiver units to be integrated into the boundary wall while simultaneously minimizing transmission losses.

[0018] The cover preferably has a circumferential support edge with which the cover surrounds the transmitting and receiving unit and rests on the boundary wall in the recess, whereby the cover is significantly more resilient and can be fastened in the recess, for example by gluing.

[0019] Alternatively, the recess forms a through-hole in the boundary wall, which is closed by the cover. Such a through-hole only slightly reduces the strength of the boundary wall. However, the transmission performance is still very good with this design.

[0020] In a further embodiment, the transmitting and receiving unit is attached to the side of the cover facing the receiving space. This direct arrangement on the cover minimizes transmission losses. The design remains simple, especially since the electrical connection can be established directly to the communication module or the charging control unit without the need for additional openings.

[0021] Alternatively, the transmitting and receiving unit can be arranged within the cover and covered by the cover from the exposed surface and the receiving space. This can be achieved, for example, by encapsulating the transmitting and receiving unit. This can also be achieved by encapsulating the transmitting and receiving unit directly in the surface-formed recess if this is essentially closed off from the receiving space by the boundary wall. The transmitting and receiving unit is accordingly encapsulated and well protected from damage. The transmitting and receiving unit can advantageously also be arranged directly opposite the cover in an electronics box that is arranged in the receiving space and in which electronic components for charging control are located. This facilitates the electrical connection because the transmitting and receiving unit is arranged in the same protected space as the charging controller.The transmitting and receiving unit can also be protected from moisture and dirt in this way if an encapsulated electronics box is used.

[0022] In a preferred embodiment, the electronics box is attached to the boundary wall in which the recess is formed. This ensures optimal alignment of the electronic components with respect to the boundary wall, in which, for example, a viewing window for reading the energy meter or the charge level can be formed.

[0023] In a more advanced version, the electronics box is designed to be open to the boundary wall to which it is attached, and closed by the boundary wall. This allows easy access to the electronics box without compromising its watertightness.

[0024] In an alternative embodiment, the electronics box is made of plastic and is closed on all sides, with the transmitting and receiving unit being arranged directly opposite the wall of the electronics box facing the boundary wall. This means that only the wall of the electronics box and the cover, neither of which absorbs radio waves, are arranged between the transmitting and receiving unit and the surroundings. Accordingly, the transmitting and receiving unit can be pre-assembled and connected in the encapsulated electronics box. The transmitting and receiving performance is nevertheless only slightly restricted. The boundary wall, in which the recess is formed, is advantageously formed by a protective cover that closes the receiving space and has a surface that forms a walking or driving surface.Accordingly, the radio waves can leave the curb, paving stone, or kerb charging device upwards toward the user or the radio mast largely unhindered. The protective cover is removable from the rest of the curb, paving stone, or kerb charging unit and is made of steel. The arrangement of the cover on the protective cover can be pre-assembled independently of the rest of the unit.

[0025] It is particularly advantageous if the protective cover has an opening that is closed by a maintenance cover, with the recess being formed on the maintenance cover. The arrangement of the transmitting and receiving units can thus be implemented on a small component. The antenna can also be easily replaced with the maintenance cover. A flush finish is achieved despite the arrangement of the transmitting and receiving units. Nevertheless, a high level of strength is achieved, especially if the maintenance cover rests on an edge of the protective cover all the way around.

[0026] Alternatively, the protective cover has an opening that is closed by a maintenance cover that forms the cover. In this version, the cover is removable from the protective cover and provides access to the housing and / or the electronics box. This fulfills two functions in one component.

[0027] The transmission and reception performance of the transmitting and receiving unit is largely interference-free, in particular, if only air or non-metallic components are arranged in a space between the projection surface in which the transmitting and receiving unit is arranged and the cover, so that no materials that absorb radio waves are arranged upwards towards the environment.

[0028] The material of the cover can be glass, plastic or ceramic, which is abrasion-resistant, chemically resistant and UV-resistant, thus ensuring a long service life.

[0029] Preferably, an electrical connection cable of the transmitting and receiving unit extends from the transmitting and receiving unit to a connection contact on the electronics box or to a charging control unit within the electronics box. This can be done either by providing a plug on the electronics box, the opposite end of which is connected to the charging control unit or a separate communications module. Alternatively, depending on the arrangement, the cable can be connected directly to the charging control unit or the communications module.

[0030] This creates a curb, paving stone, or kerb charging device for charging an energy storage device of an electrically powered vehicle. The transmitting and receiving unit exhibits excellent transmitting and receiving performance, as radio wave-absorbing components between the transmitting and receiving units are avoided, thus reducing potential shielding. At the same time, the curb, paving stone, or kerb charging device is extremely robust, as high-strength metal covers can be used. The cover protects the transmitting and receiving units from external influences such as moisture, ultraviolet radiation, chemical substances, temperature, or other weather conditions, as well as mechanical stress. This ensures good communication between the operator's server and the user, as well as the charging device, at all times.Two non-limiting embodiments of a curb, paving stone or kerb charging device according to the invention for charging an energy storage device of an electrically driven vehicle are described below with reference to the figures.

[0031] Figure 1 shows a schematic diagram of a road with a limiting curb loading device according to the invention in plan view.

[0032] Figure 2 shows a perspective top view of the curbstone, paving stone or kerbstone loading device according to the invention from Figure 2 with the cover open.

[0033] Figure 3 shows a side view of a section of a curbstone, paving stone or kerbstone loading device according to the invention in a sectional view.

[0034] Figure 4 shows a side view of a section of a curbstone, paving stone or kerbstone loading device according to the invention as an alternative to Figure 3 in a sectional view.

[0035] 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 curb or kerb charging devices 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. Charging 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.

[0036] The curbstone, paving stone, or kerbstone loading device 18 consists, as can be seen in Figure 2, of a curbstone element 34, which consists of a base body 36 made of any material of sufficient strength, in particular concrete, natural stone, or a plastic, which may contain fiber reinforcements, and a receiving container 38, in particular made of steel, which delimits a receiving space 40. The receiving container 38 is essentially hollow cuboid-shaped and has an open side facing upwards toward the sidewalk 10, which is closed by a protective cover 42.

[0037] The protective cover 42, which is made in particular of steel, is attached via screws 44 to the eyes 46 of the receiving container 38, which is glued into the base body 36, and closes the upwardly facing, open side of the receiving container 38, in particular with the interposition of a seal, which is not shown. In addition, the protective cover 42 also rests on an upper side of the base body 36 and, viewed in the longitudinal direction, also extends over the ends of the receiving container 38.

[0038] The protective cover 42 has a rounded impact wall 48, which covers an edge between the upper side of the base body 36 and a side surface of the base body 36 facing the street. The protective cover 42 accordingly defines the upper boundary of the receiving space 40 formed inside the receiving container 38 and thus inside the curb element 34. The protective cover 42 thus forms a boundary wall 50 of the curb element 34, which is exposed to the outside environment, is usually metallic or fiber-reinforced and electrically conductive, but is preferably made of steel, at least in the loaded areas.

[0039] Furthermore, Figure 2 shows that an opening 52 and two recesses 54, 56 are formed on the protective cover 42. The opening 52 is closed by a pivoting part 58, to which an interface 60 in the form of a charging socket 24 is fastened, which is part of a charging unit 61 formed on the curb element 34. The charging unit 61 can be pivoted with the pivoting part 58, for example via an electric motor (not shown), from the extended position shown in Figure 2 into a retracted position in which the charging socket 24 is arranged in the receiving space 40 and is inaccessible from the outside. A pivoting back into the extended position is also effected by the electric motor.

[0040] The first recess 54 is covered and sealed by a first cover 62 made of shatterproof and scratch-resistant glass or a transparent plastic. Visible beneath the cover 62 are a display unit 64 of an energy meter and a first transmitting and receiving unit 66 in the form of an RFID antenna 68, which also form part of the charging unit 61. The glass is a non-conductive and non-metallic material that absorbs radio waves only to a negligible extent, so that the RFID antenna 68, located directly beneath the glass, achieves very high transmitting and receiving power.The transmitting and receiving unit 66 is located directly beneath the glass cover 62, so that it is arranged within a projection surface formed by a projection of the surroundings of the curb element 34 perpendicularly onto a wall surface 70 of the cover 62 that is exposed to the surroundings, without any additional components that interfere with the radio waves being arranged between the RFID antenna 68 and the cover 62. The second recess 56 is covered by a further non-metallic cover 72, in particular made of plastic. Figure 3 shows that a further transmitting and receiving unit 73 in the form of a mobile radio antenna 74, in particular a 4G antenna, is arranged beneath the cover 72. The mobile radio antenna 74 is arranged in the second recess 56, which is formed only on a surface 75 of the protective cover 42 that faces the surroundings.Accordingly, the mobile radio antenna 74 rests in the recess 56, preferably with a thin plastic layer interposed on the protective cover 42, or is otherwise fastened at a small distance from the surface of the protective cover 42 in the space between the protective cover 42 and the cover 72 in the region of the recess 56. For better fixation and greater durability, the cover 72 has a circumferential outer projecting support edge 77 that surrounds the mobile radio antenna 74 and with which the cover 72 rests on the protective cover 42 within the recess 56, so that the cover 72 can also be glued here if necessary. In the protective cover 42, only a small through-opening 80 is formed in the region of the recess 56 in order to be able to guide an electrical connection cable 76 of the mobile radio antenna 74 to a charging control unit 82 of the charging unit 61, which is not shown in Figure 3 for the sake of simplicity.The opening 80 is sealed from the interior of the receiving space 40. The mobile radio antenna 74 is also covered at the top only by the cover 72, so that the radio waves can penetrate to the outside largely unhindered, thus establishing good communication with the user and the server operator. The protective cover 42, which serves as the boundary wall 50, is essentially closed by the pivoting part 58 and the two covers 62, 72, so that no water or dirt can penetrate into the receiving space 40. The charging control unit 82 is arranged inside a dust- and liquid-tight electronics box 84, which can accommodate all the necessary electronic components of the charging unit 61 for controlling the charging process. In the section of Figure 3, in addition to the charging control unit 82, to which the two transmitting and receiving units 66, 73 are connected, a power supply unit 86 and various terminal blocks 88 can be seen.Furthermore, a control unit 90 for the electric motor of the pivoting part 58 is shown in the electronics box 84. Except for the side facing the protective cover 42, the electronics box 84 is completely closed and has only sealed openings for the electrical connections of the electric motor, the charging socket 24, the transmitting and receiving units 66, 73, and the power supply cable 22, which is led through the bottom of the base body 36 into the receiving space 40 and is connected to the electronics box 84 in the upper area below the protective cover 42 via a quick-release coupling or clamp. The electronics box 84 is connected to the protective cover 42 by screws with a seal 92 interposed, thus tightly sealing it.

[0041] Figure 4 shows an alternative arrangement of the transmitting and receiving unit 73. In this embodiment, the transmitting and receiving unit 73 is fastened to a holder 94 in the electronics box 84 and can thus be pre-assembled in the electronics box 84. Nevertheless, the transmitting and receiving unit 73 is arranged such that it is located within a projection surface formed by a projection of the surroundings of the curb element 34 perpendicularly onto an outer wall surface 96 of the cover 72, wherein the outer wall surface 96 is in a plane with the surface of the protective cover. In other words, the transmitting and receiving unit 73 is arranged directly below the cover 72 in the receiving space 40, without any other components that could influence the transmitting and receiving performance being arranged in the space between them.Instead, the transmitting and receiving unit 73 is placed on the side of the protective cover 42 opposite the surface of the protective cover 42 forming the sidewalk 10, directly below the cover 72.

[0042] If a vehicle 32 is to be charged via the charging unit 61 in the curb element 34, the user is first identified, for example, by their vehicle 32 or a fuel card or similar, via the RFID antenna 68. Data is then exchanged between the user, for example via a mobile phone, the operator's server, and the charging control unit 82 via the mobile radio antenna 74. A connection can also be established from the user to an operator's server and thus to the curb, paving stone, or kerb charging device 18 via the transmitting and receiving unit 73, in order to be able to start and end the charging process from outside.

[0043] After identification, the charging control unit 82 activates the control unit 90, which serves to control the electric motor of the lifting or pivoting mechanism to pivot the charging socket 24. Accordingly, the charging socket 24 is extended so that the plug 26 can be plugged in. For this purpose, the actuator comprising the electric motor, which is supplied with low voltage via the control unit 90 and the power supply unit 86 connected to it, has a position feedback unit, for example in the form of a magnetoresistive sensor interacting with a permanent magnet or a light barrier, via which the position of the lifting mechanism can be detected, so that the extension process is completed when a defined end position is reached.

[0044] After plugging in the connector 26 and before the charging process begins, a locking actuator is activated, preventing accidental removal of the connector 26 during the charging process, as this would endanger the user. Only after the locking actuator is activated is a power contactor activated via the charging control unit 82, allowing the charging process to begin.

[0045] The energy meter has a data interface in the form of a ModBus to the charging control unit 82, so that the energy meter data is transmitted to the charging control unit 82 during the charging process and terminated upon completion of the charging process due to an external command or the detection of a full charge of the energy storage device 30. The user is either connected to the backend via their mobile device, and the backend is connected to the charging device via the Internet, or the user is identified directly by the charging unit via the RFID antenna, which in turn is connected to the backend via the Internet for status display and billing. The energy meter data can thus be continuously transmitted via the mobile antenna 74 to the operator's server, which then transmits it to the user if necessary.Subsequently, the power contactor is switched via the charging control unit 82 and the locking actuator is released, so that the plug 26 can be removed from the charging socket 24. The pivoting part 58 of the charging socket 24 is then actuated by the electric motor, and the charging socket 24 is retracted into the receiving space 40.

[0046] The arrangement of the transmitting and receiving units within the projection surface of the covers leads to an undisturbed and reliable data exchange through the use of non-metallic and therefore radio wave-absorbing materials.

[0047] It should be clear that the electronics can be adapted to the respective circumstances, especially the legal requirements of the countries. Furthermore, the described embodiments are not restrictive. Thus, both transmitting and receiving units do not necessarily have to be used. It is also conceivable, for example, as claimed, to encapsulate the transmitting and receiving units in the covers or to attach them to the backs of the covers, facing away from the environment.
