Description

Technical Field

[0001] The invention relates to a curbstone charging device, a shoulder stone charging device or a paving stone charging device for charging an energy storage device of an electrically driven vehicle, having: a base body made of metal, concrete, natural stone, plastic or composite material; an internal receiving space bounded by the base body at a plurality of sides; a cover for closing the receiving space; components of a charging unit arranged in the receiving space; and a charging socket mechanically connected to the cover at least indirectly. Background Art

[0002] The curbstone charging device and the shoulder stone charging device are charging stations integrated in the curbstone and the shoulder stone, and a vehicle can be connected to the charging station via an electrical connection device to charge its energy storage device or its battery. This particularly relates to purely electrically driven vehicles, but also to hybrid vehicles. The rechargeable vehicles can be not only passenger cars, but also heavy vehicles, motorcycles or electric bicycles.

[0003] Due to new legislation, the continuously growing public interest in climate protection, and the improved economy of electrified vehicles, it is expected that the share of electric vehicles will increase sharply, especially in the urban area, such that the available charging infrastructure must be expanded to a large extent, which means that a part of the existing parking lots must be provided with corresponding charging feasibility in order to ensure individual mobility also in the future.

[0004] For this purpose, known concepts propose to use street lamps, additional charging piles to be installed, or wall boxes on house walls. In all these concepts, additional space requirements are generated, and pedestrians are disturbed due to the charging cables to be used.

[0005] For the reasons mentioned above, charging systems in which the charging device is integrated into the curbstone or the shoulder stone are already known. This has the advantages that the charging pile does not block the sidewalk and thus does not affect the visual impression. On the contrary, no additional space requirements are generated, but only the existing infrastructure is utilized. High flexibility and adaptability are achieved through feasible modularization. It is also possible to prevent the charging device from being damaged by a vehicle accident.

[0006] A specific configuration of such a curbstone having an electronic device for charging a vehicle is known from WO 2021 / 156621A1. The curbstone is modularly constructed and has a base element into which a replaceable receiving container can be inserted. Components for charging the vehicle's battery are arranged in the container. The receiving container is open upward and is closed by a cover, and the cover bounds the base element toward the road by an inclined wall. The base element, as well as the container and the cover, are made of plastic. Additionally, an implementation is known in which the components can be removed from the cover.

[0007] The problem with the curbstone implemented in this way is that in the case of rainfall and temperatures below 0 °C, the mobility of the components is restricted. In the embodiment of the fixedly installed charging socket, the cover may also freeze. In addition, the curbstone does not have preventive measures through which the output energy or status can be read. In the case of heavy snowfall, such a curbstone may not even be found anymore and poses a slipping hazard. Problems in authentication may also arise. Summary of the Invention

[0008] Therefore, the following object is proposed: to provide a curbstone charging device, a shoulder stone charging device or a paving stone charging device for charging the energy storage device of an electrically driven vehicle, by means of which winter operation can also be reliably carried out. Here, not only the mobility of the components that can move relative to each other should be ensured, but also the free visibility of the display should be ensured. The functionality and accessibility of the charging socket should also be ensured.

[0009] The object is achieved by a curbstone charging device, a shoulder stone charging device or a paving stone charging device for charging the energy storage device of an electrically driven vehicle having the features of independent claim 1.

[0010] The curb charging device, shoulder charging device or paving stone charging device for charging an energy storage device of an electrically driven vehicle according to the invention has a base body, which is made of metal, concrete, natural stone, plastic or a composite material, for example by casting. Concrete can currently also be understood as ultra-high-strength concrete (UHPC), fiber-reinforced concrete or polymer concrete, in which plastic is used as an adhesive instead of the binder cement. An accommodation space is formed inside the base body, and the accommodation space is bounded by the base body at multiple sides. The base body particularly has a bottom and three or four side walls. The accommodation space is closed, for example, by placing it on the upwardly directed ends of the four side walls. However, the cover can of course also form one or more side walls of the accommodation space. Components of the charging unit are provided in the accommodation space, and the components are, for example, fastened to the cover, but can also be fastened to the base body. The components of the charging unit can not only form a completely autonomous charging unit that only requires current terminals and itself includes all electronic components, but can also exist individually and be used in any arbitrary manner for regulating or protecting the charging socket and the charging process. Correspondingly, individual electronic components of the charging unit, such as an energy meter, a charging controller, a power contactor or a transmitting and receiving unit for authentication, etc., can also be provided in the accommodation space. Therefore, the components of the charging unit are understood as single components or multiple components that can be used to charge the energy storage device of an electric vehicle or a hybrid vehicle. In addition, the curb charging device, shoulder charging device or paving stone charging device has a charging socket, and the charging socket is at least indirectly mechanically connected to the cover. The mechanical connection can be carried out via a lifting or pivoting mechanism or via an additional component fastened to the cover. Of course, the charging socket is electrically connected to the charging unit or to the components of the charging unit.

[0011] According to the invention, the cover can be heated via a heating element. Here, heating elements implemented differently can be envisaged, and it is also possible to envisage using multiple heating elements. Since there is an existing connection between the curb charging device, shoulder charging device or paving stone charging device and a voltage source, an electrically operated heating element can particularly be used. By heating the cover in this way, it is possible to prevent components that can move relative to each other at the cover, such as a lifting or pivoting mechanism, from getting stuck due to icing, or to melt existing ice layers. This can be done prospectively or as needed. In addition, the display unit can be kept ice-free and snow-free, so that a clear view can be ensured. By heating the cover, the entire upper side can be kept ice-free and snow-free, so that the curb is always accessible. The availability of the charging socket also remains unchanged, and the socket cover that may exist can be folded if necessary. In this way, access to the transmitting and receiving unit for authentication can also be ensured. Such a curb charging device, shoulder charging device or paving stone charging device can also be fully used under winter climate conditions. However, heating the cover is sufficient here because the main components for using the curb as a charging station are provided here, and thus large-area heating can be omitted.

[0012] The cover is preferably made of metal, thereby ensuring good thermal conductivity, so that heating of the entire surface does not have to be ensured via one or more heating elements, but rather a small heating surface is sufficient due to heat conduction.

[0013] Particularly preferably, a resistance wire is used as the heating element. Such a resistance wire is also called a heating wire and is produced by a heating conductor alloy consisting of two or more metals, which have a relatively high specific electrical resistance and a low tendency to oxidize, and whose purpose is accordingly to convert electrical energy into heat. Such a resistance wire requires almost no structural space and can be easily laid out at a specific location in order to introduce heat in a targeted manner. In addition, the resistance wire can be operated cost-effectively at a low voltage of, for example, 12 V and has a high heat resistance.

[0014] In an embodiment which improves this, the resistance wire is integrated in a seal which is arranged between the cover and a component connected to the cover. In this way, additional insulation of the wire is not necessary and the heating element is introduced in one assembly step by means of the seal which is required anyway, so that an additional assembly step is omitted. Furthermore, when integrated in the seal between the base body and the cover, the cover is heated from all sides in this way, so that rapid and complete heating of the cover is ensured.

[0015] In an advantageous embodiment of the invention, the electronics box and / or the charging socket are fastened to the cover, wherein a seal with a resistance wire is provided between the flange surfaces of the electronics box and / or the charging socket for the cover. Accordingly, not only is good visibility of the display unit of the energy meter arranged in the electronics box ensured, but also free accessibility and functionality of the charging socket and free mobility of the socket cover, which may be present, is ensured, since the cover is heated in the vicinity of the critical components by the resistance wire.

[0016] Preferably, a groove is formed in the cover or at the free end of the side wall of the receiving space of the base body covered by the cover or at the flange surface of the electronics box facing the cover, in which groove the resistance wire is arranged. The resistance wire can either be simply inserted into the groove as an insulated resistance wire or inserted together with the seal. In both cases, the cover is heated over a large section, so that in particular the critical parts of the cover to be heated can be heated to the desired temperature in a short time in order to melt ice or snow layers.

[0017] In an improved embodiment, the groove is formed around the open side of the receiving space of the base body, which is closed by the cover. The surrounding configuration of the groove and the resistance wire makes it possible to heat the entire cover to the desired temperature in a short time in order to clear ice and snow from the cover.

[0018] Particularly advantageously, a seal is provided in the groove in addition to the resistance wire, and the gap between the base body and the cover is sealed via the seal. Thus, in one installation step, not only the sealing device of the cover can be introduced, but also the heating element can be introduced.

[0019] Preferably, the resistance wire is insulated so as to avoid conductive contact with the surrounding housing.

[0020] Particularly preferably, the resistance wire is fastened by means of a thermally conductive adhesive. This can be done in the groove or planar at the cover. Thus, the heat conduction to the cover is improved and the heating time is shortened.

[0021] In another advantageous embodiment, the heating element extends around the receiving opening of the charging socket. Thus, the functionality of the charging socket at temperatures below freezing point is ensured because the ice layer is dissolved. Thus, on the one hand, the socket cover that may be present can be simply flipped open, and on the other hand, the charging socket itself is prevented from freezing, so that problems when inserting the plug into the charging socket are avoided.

[0022] It is also advantageous that the heating element extends around the opening that houses the transmitting and receiving unit, in particular the RFID antenna. Thus, communication between the user and the charging control device or the provider's server can also be ensured in the case of ice and snow.

[0023] Furthermore, the charging socket can preferably be moved out of the opening in the cover via a pivot member, where the heating element extends around the opening, and the pivot member pivots out of the cover from the opening. This pivoting socket has the advantage that the user can better access the pivoting socket, and outside the charging process, the charging socket is protected in the receiving space. The ice layer that may be present in the gap between the cover and the pivot member is dissolved by the heating element or may not form at all in the first place, so that functionality exists in all climatic conditions.

[0024] To ensure the legal requirement of the feasible readability of the energy meter at any time, the charging unit has an energy meter, and the energy meter has a display unit that can be read through the opening or window in the cover, where the opening or window is at least partially surrounded by the heating element. Thus, the window of the display unit remains visible at all times.

[0025] In another preferred embodiment, a temperature sensor is provided in the cover, and the temperature of the cover can be measured via the temperature sensor. Via the temperature sensor, the external temperature can be inferred outside the heating time, so as to determine whether icing is to be feared. At the same time, the temperature of the cover can be measured during heating, and one or more heating elements can be adjusted accordingly.

[0026] Furthermore, a temperature sensor may alternatively or additionally be provided at the curbstone charging device, the shoulder stone charging device, or the paving stone charging device, and the external temperature can be measured via the temperature sensor, such that adjustment can also be made only based on the external temperature.

[0027] Therefore, in order to reduce current consumption, the heating element is adjusted according to the measured value of the temperature sensor.

[0028] For this purpose, the temperature sensor and the heating element are electrically connected to the charging regulator of the charging unit or a separate control unit. By using the charging regulator of the charging unit for adjusting the resistance wire via the measured value of the temperature sensor, additional components can be omitted. Furthermore, the measured value of the temperature sensor can also be utilized during charging adjustment if this is desired.

[0029] It is also advantageous that the heating element can be adjusted according to meteorological data, which can be transmitted to the control unit of the heating element or the charging regulator via the transmitting and receiving unit in the form of a radio interface of the curbstone charging device, the shoulder stone charging device, or the paving stone charging device. In this case, the temperature sensor can be omitted if necessary, or the data can be additionally used. This can also enable preventive heating of the cover in order to avoid any icing or snow accumulation at the curbstone, the shoulder stone, or the paving stone.

[0030] In an alternative configuration with respect to the resistance wire, a heating pad or a heating cylinder is fastened to the cover as the heating element. The heating pad is usually composed of plastic in which wires are embedded. Thus, uniform and large-area heating of the cover can be achieved. The heating cylinder is an electric heating rod, by means of which the entire accommodation space can also be heated.

[0031] Alternatively, a heat radiator, especially an infrared radiator, is provided in the accommodation space, which can generate a heat flow towards the cover or irradiate the cover. In this way, heating of the cover can also be achieved over a large area.

[0032] Furthermore, alternatively, a conducting element is provided in the accommodation space, which conducts the waste heat of the pivot drive, the locking actuator, or the charging unit of the charging socket to the cover. For this purpose, for example, the pivot drive or the locking actuator can be energized without generating movement, such that only waste heat is generated. By conducting the heat to the cover via the conducting element, targeted heating of the cover is also feasible. The waste heat of the heat-generating components of the charging unit can also be correspondingly conducted to the cover via the conducting element and the cover can be heated accordingly.

[0033] Yet alternatively, an induction element can be provided at the cover, via which induction heat can be generated in the conductive cover, thereby also providing sufficient heat for melting the ice layer or the snow layer.

[0034] Alternatively, a heat pump, in particular an air heat pump, is provided in the accommodation space for heating.

[0035] Accordingly, a curbstone charging device, a shoulder stone charging device or a paving stone charging device for charging an energy storage device of an electrically driven vehicle is realized, and all functions of the charging device are ensured by means of the curbstone charging device, the shoulder stone charging device or the paving stone charging device, independently of the weather conditions and temperatures below 0 °C. The heating device can be placed in a targeted manner in critical areas, where the installation cost and the cost consumption are very low. The heating of the cover is either carried out only when needed, i.e. for example when the pivot element of the charging socket has frozen and the ice must be melted accordingly, or a temperature window can be defined in which heating is carried out preventively to avoid premature freezing. It can also be connected to the charging unit in order to inform, for example, the server of the service provider about the current temperature of the cover or the operating state of the heating device, or vice versa, meteorological data can be transmitted from the server to the charging unit, so that the heating element can be adjusted according to these values.

[0036] A non-limiting embodiment of a curbstone or paving stone or shoulder stone charging device for charging an energy storage device of an electrically driven vehicle according to the invention will be described below by taking the curbstone charging device as an example.

[0041] Figure 5 A side view of a curbstone charging device according to the invention having a heating pad is shown in a sectional view. Detailed Description

[0042] In Figure 1The sidewalk 10 is shown, which is bounded on one side by a house wall 12 and on the other side by a curb 14. The curb is formed by a plurality of stone elements 16 and a curb charging device, a shoulder stone charging device or a paving stone charging device 18 according to the invention and constitutes a boundary portion relative to the road 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 current terminal connected to the power grid. The energy source 20 is connected to the curb or shoulder stone charging device 18 via an underground power supply cable 22. At the curb or shoulder stone charging device 18, there is a charging socket 24 into which a plug 26 is inserted. The plug is connected to an energy storage device 30, in particular the battery of an electrically driven vehicle 32, via a cable 28, so that the energy storage device 30 can be charged via the energy source 20.

[0043] In Figure 2 the curb charging device, the shoulder stone charging device or the paving stone charging device 18 according to the invention is shown. Hereinafter, the terms "upper", "lower", "below", "above", etc. respectively mean the following states of the curb or shoulder stone charging device 18: The state corresponds to the state of being installed on the road edge. Therefore, the "upper side" corresponds to the side facing away from the ground in the installed state.

[0044] According Figure 2 the curb charging device, the shoulder stone charging device or the paving stone charging device 18 consists of a base body 34, which is made of steel, concrete, plastic or a composite material and may contain a fiber reinforcement portion. The base body 34 has a bottom 36, and a total of two transverse walls 38, a front wall 40 and a rear wall 42 extend upward from the bottom. The two transverse walls, the front wall and the rear wall serve as side walls 38, 40, 42 that form an accommodation space 44 inside the base body 34. The accommodation space 44 is closed by a cover 46, and the outer circumference of the cover is placed on the upwardly directed free ends 47 of the side walls 38, 40, 42.

[0045] Inside the accommodation space 44, an electronic device box 48 is provided. The electronic device box is fastened to the cover 46 via a flange surface 50, and components of a charging unit 52 are provided in the electronic device box. In addition to a charging regulator 54 as a component, the charging unit 52 further has a combined fault current and power protection switch 55, which is connected to an energy meter 56 having a display unit 58. The energy meter is connected to a charging socket 24 when a power contactor 59 is connected in the middle. In addition, a power supply component 60 is provided in the electronic device box 48. The applied high-voltage is converted into a low-voltage, especially 12V voltage, via the power supply component. The charging regulator 54 is powered by the power supply component 60, and the power contactor, which is also provided in the electronic device box 48, is switched via the charging regulator 54. Before switching the power contactor 59 via the charging regulator 54, it is necessary to switch a locking actuator 61 of the charging socket 24 and previously authenticate the user via a transmitting and receiving unit 62, for example in the form of an RFID antenna. The transmitting and receiving unit is provided under a plastic cover 64, and the plastic cover 64 closes a first opening 66 in the cover 46. Correspondingly, in the current case, the charging regulator 54, the combined fault current and power protection switch 55, the energy meter 56, the power contactor 59, the power supply component 60, and the transmitting and receiving unit 62 form components of the charging unit 52.

[0046] The display unit 58 of the energy meter 56 is under a window 68, and the window is provided in a second opening 70 at the cover 46. A third opening 72 is at the cover 46 to accommodate the charging socket 24. The charging socket is covered by a socket cover 73, and the socket cover abuts against the cover 46 with a flange surface 74 when a sealing element 75 is inserted.

[0047] In an alternative embodiment, a pivot member 76 of the pivotable charging socket 24 is provided in the third opening 72. The pivot member closes the third opening 72 outside the charging time and pivots out of the opening 72 before starting the charging process with the charging socket 24. The pivot member 76 can be designed to be slightly larger than the opening 72 and is placed on the outer edge of the opening 72 between the charging processes. For this purpose, the cover 46 and the pivot member 76 can be implemented to be slightly thinner in the vertically stacked area and can have corresponding shoulders with each other, so as to produce a smooth surface. The pivoting process is implemented by a pivot drive 78, which especially has an electric motor, and a pull rod and a push rod of the pivot drive are connected to the pivot member 76.

[0048] Now, in order to ensure that the movable components remain movable even in case of frost and ice, that the display unit 58 can also be read in case of snow, that the sending and receiving unit 62 remains accessible for radio waves, and that the charging socket 24 remains accessible and operational, a plurality of heating elements 80 are provided at the cover 46.

[0049] It should be noted that either all of the heating elements 80 can be used, or only one or more of the heating elements 80 in the sense of the present invention can also be used.

[0050] Therefore, a circumferential groove 82 is formed at the cover 46, more precisely, a circumferential groove 82 is formed at the side of the cover 46 and in the region placed on the ends 47 of the side walls 38, 40, 42. An insulated first resistance wire 80.1 is provided as the heating element 80 in the groove 82, as well as a circumferential first seal 84 to seal the gap 85 between the cover 46 and the side walls 38, 40, 42. The resistance wire 80.1 abuts directly against the cover 46 in the groove 82, while the seal 84 is placed on the ends 47 of the side walls 38, 40, 42 for sealing. The resistance wire 80.1 is fastened to the cover 46 in the groove 82 via a thermally conductive adhesive. However, it is also conceivable to integrate the resistance wire 80.1 into the seal 84.

[0051] The second resistance wire 80.2 is preferably also arranged at the cover 46 from the inside by means of a thermally conductive adhesive and surrounds the window 68 of the display unit 58 of the energy meter 56.

[0052] The third resistance wire 80.3 is in a groove 86 at the side of the cover 46 facing the flange surface 50 of the electronic device box 48 as shown in Figure 3 and a seal 88 is also provided in the groove.

[0053] The fourth resistance wire 80.4 is in the region of the cover 46 according to Figure 4 both in the variant of the pivotable member 76 having the charging socket 24 according to Figure 2 and in the case of a fixed charging socket 24, and this region surrounds the third opening 72, where in the fixed variant, the resistance wire 80.4 is clamped between the flange surface 74 of the charging socket 24 and the cover 46.

[0054] Furthermore, as shown in Figure 5 a heating pad 80.5 is fastened under the plastic cover 64 of the sending and receiving unit 62.

[0055] Thus, all critical parts that must be either accessible, visible, or movable for the function of the charging device can be heated by the heating element 80, thereby either preventing the formation of ice and snow layers before they occur or dissolving them before the charging process.

[0056] To control the heating, a temperature sensor 90 is provided on the underside of the cover 46. The temperature sensor is electrically connected to the charging regulator 54 or a separate control unit, and all of the heating elements 80 are also connected to the control unit. Correspondingly, the heating element 80 can be heated either preventively when the temperature is below a critical temperature, for example 4 °C, or before using the charging device. Subsequently, the temperature of the cover can be monitored to determine whether to dissolve the ice or snow layer based on the stored characteristic curve family. Additionally, it is feasible to transmit weather data to the charging regulator via a sending and receiving unit and initiate heating via it. The heating can be checked via the temperature sensor to correspondingly adjust the energization of the heating element.

[0057] It is clear that the described curb charging device for charging the energy storage of an electric vehicle can implement a complete charging infrastructure in a simple manner. The charging infrastructure is flexibly and modularly constructed and ensures the functionality of the charging infrastructure in all climatic conditions.

[0058] Furthermore, it should be clear that the heating elements can be adapted to the corresponding situation. In particular, it is not necessary to compulsorily use all of the described heating elements, as a single heating element at the cover may be sufficient if necessary. In addition to the described resistance wires and heating pads, heating radiators such as infrared radiators irradiating the cover or heating cartridges can also be used. Pivot drives or heat-generating components of the charging unit can also be used as heating elements, and their waste heat can be guided towards the cover via heat conduction elements.
