Description

Cable assembly for charging an electric vehicle and a parking assembly.

The invention relates to a cable arrangement for charging an electric vehicle according to the preamble of claim 1 and a parking arrangement with the cable arrangement according to claim 13.

Out of concern for the environment and with a greater awareness of climate protection, interest in electromobility is also increasing. With a rapid development of electric mobility, there is a growing demand for new, user-friendly charging stations for electric vehicles. In particular, the development of a charging infrastructure is of crucial importance for the establishment of electromobility worldwide.

Wired stations for electric vehicles often cannot be placed in the immediate vicinity of the socket located on the vehicle due to the local arrangement and/or installation conditions. As a result, charging systems can be installed in large car parks, particularly in the form of multi-storey car parks, bus garages and/or depots.

The document DE 10 2018 129 016 A1, which is probably the closest prior art, discloses a precast concrete component for parking arrangements, in particular multi-storey car parks, having at least one guide device, the at least one guide device being set up to movably support at least one charging cable carrier element, and at least one charging device attachment arrangement , which is set up for attaching at least one charging device and for charging electric vehicles, on the precast concrete component.

The invention is based on the object of creating a cable arrangement which enables improved operation. This object is achieved by a cable arrangement with the features of claim 1 and by a parking arrangement with the features of claim 13. Preferred or advantageous embodiments of the invention result from the dependent claims, the following description and/or the attached figures.

A cable arrangement is proposed which is suitable and/or designed for charging an electric vehicle. The electric vehicle is designed in particular as a vehicle with an electric drive. The electric vehicle is preferably designed as a motorcycle, a passenger car, a motor bus, a truck, a tractor, a bus and/or a self-propelled work machine. Alternatively or additionally, the electric vehicle is designed as a battery electric vehicle (BEV), hybrid vehicle (HEV) and/or plug-in hybrid electric vehicle (PHEV).

The cable arrangement includes a charging cable, a guide device and a guide device.

The charging cable is designed on the one hand for connection to a stationary charging station, in particular in a detachable or non-detachable manner, and on the other hand for connection to the electric vehicle. In particular, the charging cable is designed to charge the electric vehicle. The charging cable is preferably designed to transfer energy from the charging station to the electric vehicle. The charging cable is designed in particular as a preferably multi-core assembly of individual lines that is sheathed with insulating materials. The charging cable is designed in particular as a DC charging cable. In particular, the charging cable is a DC charging cable of the type CCS Type1, CCS Type2, CHAdeMO and/or GB/T. In particular, the charging cable is designed as an uncooled or a liquid-cooled charging cable. Alternatively or additionally, the charging cable is designed as an AC charging cable, in particular with a high level of rigidity.

The charging station provides the charging current. The charging station preferably ensures safety through overload protection and/or insulation monitoring. Optionally, the charging station prevents user errors and provides a data exchange optimum, gentle charging process. The charging station preferably has a housing. For example, the charging station is box-shaped. In particular, the charging station has a floor, a ceiling and four side walls.

The charging cable has a charging plug for connection to the electric vehicle. The charging plug is designed to be connected to the electric vehicle. In particular, the plug is designed as an interface between the charging cable and the electric vehicle. The charging connector is designed in particular as a single-phase connector type 1, a three-phase connector type 2, a CCS connector with additional power contacts, a fast charging system CHAdeMO connector and/or a connector of a GB/T standard.

The guide device is designed to specify and/or determine a direction of movement of a body, in particular of an element of the cable arrangement system. The guide device is preferably designed as a guide rail. The guide rail is designed in particular as a linear guide. In particular, the guiding device is made of metal, a combination of metals and/or metals in connection with one or more other elements. The guide device is preferably made of steel, in particular structural steel or stainless steel. In particular, the guide device extends in a horizontal direction during operation. The guide device can be arranged, for example, on a steel bridge, a ceiling and/or a plafond.

The guide device is designed to guide and/or carry the charging cable. The guiding device comprises a deflection module and at least one cable carrier.

The deflection module is implemented in particular as a direction converter and/or is designed to deflect the charging cable. The deflection module is preferably designed to guide and/or deflect the charging cable as smoothly as possible. The deflection module can have, for example, a wheel, a block, a roller, an arc of a circle or a disk as a deflection body. The deflection body is preferably arranged rotatably in the deflection module. In particular, the charging cable is via the Deflection module, in particular placed the deflection body freely movable. The charging cable is deflected and/or guided in particular by the deflection module, in particular the deflection body.

The deflection module is arranged in the guide device so that it can be displaced along the horizontal direction. The deflection module is preferably mounted on the guide device. The deflection module is designed in particular as a last element of the guide device, with the charging cable being deflected after the deflection module.

The cable carrier is designed in particular to carry and/or accommodate the charging cable. In particular, the charging cable can be mounted on the cable carrier and/or carried by it.

In a first alternative, the cable carrier is arranged in the guide device so that it can be displaced along the horizontal direction. In particular, the cable carrier can be moved depending on a position of the deflection module or by the deflection module.

In a second alternative, the cable carrier can be switched between an active state and a passive state depending on a position of the deflection module, in particular by the deflection module. In particular, the cable carrier has an active state when the charging cable is held and/or accommodated by the cable carrier. In the passive state, the cable tray has no charging cable. The cable carrier is switched at least in sections into the passive state, in particular by moving away, turning, pivoting away, rotating and/or tilting. The cable carrier is preferably arranged in a stationary manner on the guide device. Alternatively, it is also possible for the cable carrier to be arranged in a displaceable manner.

According to the invention, it is proposed that the charging cable always runs in a straight line in the guide device. In particular, the rectilinear course takes place from the beginning of the guide device to the Deflection by the deflection module. The deflection is preferably the only bend in the charging cable. In particular, the charging cable does not have a garland-shaped course. An advantage of the invention is a space-saving and lightweight design of the cable arrangement for charging the electric vehicle. A charging cable with a large cross-section can advantageously be used in the cable arrangement according to the invention. In particular, a charging cable with high rigidity can be used. In addition, a longer service life of the charging cable can be ensured by the invention, since this is only gently bent at one point along the course. This is achieved in that the charging cable is only routed in a straight line and, in particular, without any bends, except for the absolutely necessary deflection on the deflection module.

A preferred embodiment of the invention provides that the charging cable is designed to be rigid. In particular, the charging cable is difficult to bend. The charging cable preferably has greater flexural rigidity than a standard household cable, for example a telephone cable. The charging cable preferably has a cross section of at least 50 mm ² , in particular more than 80 mm ² and in particular more than 100 mm ² .

In a particularly preferred embodiment of the invention, the charging cable is routed to the deflection module along the guide device without any bends. The charging cable preferably has no curves, bends, coils, kinks and/or kinks in a region of the guide device. In particular, the charging cable to the deflection module runs parallel to the guide device. The deflection module is designed to deflect the charging cable from the horizontal direction into a vertical direction. For example, the charging cable is deflected from the horizontal direction into a vertical direction by 90° or by a range between 80° and 120°.

One embodiment of the invention provides that the deflection module has a deflection radius for deflecting the charging cable in the vertical direction. In particular, the deflection radius defines a radius of curvature of the charging cable for the deflection. The radius of curvature is preferably at least 10 cm. In particular, the radius of curvature is at least 20 cm and in particular at least 30 cm. Alternatively or additionally, the radius of curvature of the charging cable is a maximum of 53 cm, in particular a maximum of 45 and in particular a maximum of 35 cm. Provision is optionally made for the radius of curvature of the charging cable to be dependent on the current intensity of the charging cable.

A possible embodiment of the invention provides that the charging plug is opened and/or lowered by a displacement of the deflection module in a positively guided and/or positively coupled manner. A movement, in particular the shifting of the deflection module, is limited, in particular caused, by the guide device. The opening and/or lowering of the charging plug is made possible by the deflection module, in particular by a horizontal displacement of the deflection module. A movement of the charging plug in the vertical direction from top to bottom or from bottom to top is preferably made possible by the displacement of the deflection module. Alternatively or additionally, the charging connector is raised and/or lowered by moving the deflection module in connection with the gravity of the charging connector.

Provision is preferably made for the deflection module to be displaced with the aid of a motor. In particular, the shifting of the deflection module, in particular the opening and/or lowering of the charging plug, takes place with the aid of an electric drive unit. Alternatively or additionally, the deflection module can be moved back and forth manually on the guide device. In particular, the deflection module can be manually shifted in the horizontal direction. Optionally, manual displacement can be performed with a rod and/or rod. Optionally, the rod can be mechanically coupled to the deflection module.

In one embodiment of the invention, the guide device has the deflection module and at least one of the displaceable cable carriers. In particular, the slidable cable carrier is arranged to be slidable along the horizontal direction. The deflection module and the at least one displaceable cable carrier are preferably connected to one another with a traction mechanism. In particular, adjacent cable carriers are connected to one another with such a traction mechanism. In particular, the sliding cable carrier using the traction means displaceable and/or movable. The horizontal displacement of the deflection mode preferably causes the cable carriers to be pulled along and/or moved together. For example, a length of the traction device defines a maximum distance between the displaceable cable carrier and/or the deflection module. Appropriately selected distances between the displaceable cable carriers and the deflection module, in particular by an appropriately selected length of the traction means, prevent the charging cable from sagging and/or bending. In particular, a combination of a specific stiffness of the charging cable and the correspondingly selected length of the traction means prevents the charging cable from sagging and/or bending.

The traction means is preferably designed as a chain, a rope, a belt, a belt and/or a band. The traction means preferably has a high tear resistance.

A further embodiment of the invention provides that the guiding device has the deflection module and at least one switchable cable carrier. The switchable cable carrier can be switched to the active state and/or passive state with the help of the deflection module. In particular, when the deflection module is displaced, a position of the cable carrier is changed, with the cable carrier being switched from the active state to the passive state or in the opposite direction when the position is changed. The cable carrier is stationary. When the deflection module is displaced along the guide device, the deflection module requires space to move. Without further measures, the fixed cable carriers would be disruptive contours in this driving space, since the charging cable takes a straight course in the driving space and the deflection module has to be passed through the same positions where the cable carrier or cable carriers are present. Provision is made for the cable carriers to be arranged in the passive state in such a way that they no longer form any interfering contours in the driving space.

For example, the switchable cable carrier has a crescent-like carrying section. The sickle-like carrying section is designed to accommodate and/or hold the charging cable. Alternatively or additionally, the carrying section is designed as a hook. In particular in the active state, the carrying section the charging cable, wherein the support portion has no charging cable in the passive state.

In a preferred development of the invention, the switchable cable carrier has a switchover section which can be actuated by the deflection module. In particular, the switching section is actuated by a movement of the deflection module. When the switching section is actuated, the cable carrier is pivoted about an axis of rotation. By pivoting about the axis of rotation, the cable carrier is pivoted out of the driving space when the cable carrier is switched to the passive state and pivoted into the driving space when the cable carrier is switched to the active state. The axis of rotation is preferably aligned perpendicular to the longitudinal extent of the guide device. In particular, the axis of rotation runs vertically and/or perpendicularly.

In a preferred embodiment, the cable carrier has an L-shaped switchover section. In particular, the L-shaped switching section has L-shaped operating surfaces. The extension of the L-shaped switching portion is aligned in a plane perpendicular to the axis of rotation. When the deflection module is moved in a first direction, the deflection module moves against a first leg of the L-shaped switchover section and rotates the switchable cable carrier by 90°, for example, about the axis of rotation. When the deflection module is moved in a second direction, in the opposite direction to the first direction, the deflection module moves against the second leg of the L-shaped switchover section and rotates the switchable cable carrier back again. When the deflection module is driven through and/or displaced, in particular when there is contact between the deflection module and the L-shaped switchover section, the cable carrier can be switched to the active and/or passive state.

Alternatively, the cable carrier is pivotally mounted. In particular, the switchable cable carrier is pivoted and/or folded over from a vertical to a horizontal direction by the displacement of the deflection module, so that the cable carrier can assume the active and/or passive state. One embodiment of the invention provides that the cable arrangement can assume a charging state and an idle state. The cable arrangement defines a device length, the device length extending between a stationary end point for the director module and the director module in the current position.

In the resting state, the device length is made larger than in the charging state. Specifically, the device length has a maximum value in the idle state. In particular, the distance between the cable trays and the switching module is greatest in the idle state. In particular, the traction mechanism is taut and/or tense in the idle state. In the case of the switchable cable carriers, these are in the active state.

In the charging state, the charging cable, in particular the charging plug, can be releasably connected or is connected to the electric vehicle. In particular, the electric car is charged in the charge state. The switchover module and/or the cable carrier is/are preferably arranged adjacent to the end point in the charging state, in particular directly adjacent to one another. In the loading state, the traction mechanism is in particular in a loose and/or tensioned state. In the case of the switchable cable carriers, these are in the passive state.

The charging cable is arranged in a straight line and/or without any bends along the length of the device, both in the idle state and in the charging state.

The charging cable can preferably be connected directly to the stationary charging station. The charging cable is preferably connected to one of the side walls of the charging station. A connection, in particular an outlet of the charging cable, is preferably arranged in a direction of extension of the guide device.

A further object of the invention is a parking arrangement. The parking assembly includes a plurality of the cable assemblies. It is envisaged that the cable arrangements are arranged parallel to one another. A parking arrangement can be designed in particular as a garage and/or a hall be. In particular, the parking arrangement is embodied as an underground garage, a parking garage, bus garage and/or a bus depot.

FIG. 3 shows a schematic sectional view of an embodiment of a suspension of the cable carrier 8 according to the present invention. The cable carrier 8 is guided in a guide device 5 .

In the present case, the guide device 5 is designed as a guide rail. The guide device 5, in particular the guide rail, has an H profile. The guide device 5 is mounted directly on a ceiling 16 of a building, in particular a garage. The guide device 5 is designed to positively guide the cable carrier 8 in the horizontal direction.

The cable carrier 8 comprises a guide section 10 and a holding section 11 . The guide section 10 has the shape of a C-profile.

It is envisaged that, according to other variants of the invention, other variants of the mounting section 11 can also be used.

FIG. 4 shows a schematic front view of an exemplary embodiment of the cable arrangement 1 according to the invention. The arrangement shown includes the guide device 5 and the deflection module 7. The guide device 5 is mounted here with a fastening profile 15, for example on a ceiling 16 of a garage. The deflection module 7 is designed as a deflection roller and has a receiving channel 17 . The receiving channel 17 is designed to receive the charging cable 2 . In particular, the receiving channel 17 is designed to guide and/or steer the charging cable 2 with as little friction as possible. The deflection module 7 is mechanically connected in particular to an electric drive unit 18 .

In particular, the electric drive unit 18 is connected to the deflection module 7 on the one hand and to the ceiling 16 on the other hand. The electric drive unit 18 is designed, for example, as a garage drive. In particular, the electric drive unit 18 is designed as a trailing cable. The electrical drive unit 18 is designed to convert electrical energy into mechanical kinetic energy. In particular, the electrical energy is converted into a linear movement. Due to the mechanical connection of the electric drive unit 18 and the deflection module 7, the cable arrangement 1 is set in motion. In particular, the deflection module 7 is set in motion, as a result of which the cable carrier 8 is displaced.

The deflection module 7 is forcibly guided along the guide device 5 by a motor-assisted movement of the electric drive unit 18 . The forcibly guided displacement of the deflection module 7 causes a movement, in particular a displacement of the cable carrier 8. The cable carrier 8 is preferably displaced and/or dragged along by the deflection module 7.

The electric drive unit 18 is designed to move the deflection module 7 between an initial position 23 and an end position 24 . The starting position 23 is located in an area of the charging station 3 . In particular, the starting position 23 can be arranged in an area of the end point 19 , with the end position 24 being arranged in the area of the opposite end of the guide device 5 .

In the initial position 23, the device length V (see Fig. 2) has the minimum value. When the deflection module 7 is moved from the starting position 23 to the end position 24, the value of the device length V increases. The height H can have the minimum value. In particular, by shifting, the value of the height H becomes smaller and smaller by pulling the charging connector 4 upward in the horizontal direction. The cable carriers 8 are dragged along and/or tracked by the deflection module 7 with the aid of the traction means 9, so that the device length V reaches the maximum value in a resting state

During the forcibly guided displacement of the deflection module 7 from the end position 24 to the initial position 23, the height H assumes the maximum value, in that the charging plug 4 is lowered downwards in the horizontal direction. Preferably, the charging cable 2 is lowered down in connection with the gravity of the charging plug 4 . The device length V is reduced. Specifically, the device length V has the minimum value. In particular, the deflection module 7 is arranged at the smallest possible distance from the charging station 3 . FIG. 5 shows a schematic side view of a second exemplary embodiment of the cable arrangement 1 according to the invention in the idle state. To avoid repetition, essentially only the differences from the embodiments according to FIGS. 1 to 4 are described below.

The cable arrangement 1 shown in FIG. 5 has the charging cable 2 , the guide device 5 and the guide device 6 . The guide device 6 comprises in particular the deflection module 7 and a plurality of cable carriers 8. In contrast to the previous figures, the cable carriers 8 are designed as switchable cable carriers 8 which can be switched between an active state and a passive state. The switchable cable carriers 8 are arranged stationary in the horizontal direction, the switchable cable carriers 8 being arranged such that they can be rotated or at least pivoted about a vertical axis of rotation.

The switchable cable carrier 8 has, in particular, a sickle-like carrying section 21 . The crescent-like support portion 21 is formed as a hook. In particular, the carrying section 21 is designed to hold and/or receive the charging cable 2 .

The deflection module 7 has a switching unit 20 . The switchover unit 20 is designed as an actuating element of the deflection module 7 for switching over the switchable cable carrier 8 . In particular, the switching unit 20 is designed to change a position of the cable carrier 8 .

The switchable cable carrier 8 has an L-shaped switchover section 22 . In particular, the L-shaped switchover section 22 is formed as an angle. The switching section 22 comprises two struts, the struts being arranged at right angles and/or non-parallel to one another.

FIG. 5 shows the switchable cable carrier 8 in the active state. In the active state, the switchable cable carriers 8 have a charging cable 2 . In particular, the charging cable 2 is carried by the switchable cable carriers 8 in the active state. The switchable cable carrier 8 is switched to the passive state by the movement of the deflection module 7 . In particular, the switchable cable carrier 8 is switched over when the deflection module 7 is driven past. The switchable cable carrier 8 is switched over by the deflection module 7 at the switching section 22 by the switching unit 20 of the deflection module 7 . The switchable cable carrier 8 is rotated about its vertical axis of rotation by approximately 90° by a contact of the switchover unit 20 with a leg of the L-shaped switchover section 22 . The rotation causes the charging cable 2 to be released by the switchable cable carrier 8 so that the steerable cable carrier 8 is in the passive state. In this passive state, a driving space is released for the deflection module 7 so that it can move without a collision. Furthermore, the deflection module 7 can be moved in the direction of the initial position 23 in order to bring the cable arrangement 1 into the charging state, with all the cable carriers 8 being switched to the passive state on the way to the initial position 23 .

When the cable arrangement is transferred from the charging state to the idle state, the deflection module 7 is moved in the direction of the end position 24 . In this case, all the cable carriers 8 are switched from the passive state to the active state one after the other. The contact between the switching unit 20 and the other leg of the L-shaped switching section 22 rotates the cable carrier 8 about its vertical axis of rotation by approximately 90° in the opposite direction, so that it is again in the active state. In this exemplary embodiment, too, the charging cable 2 is routed along the length V of the device in a straight line and/or without any bends.

FIG. 6 shows a schematic side view of a third exemplary embodiment of the cable arrangement 1 according to the invention in the idle state. To avoid repetition, essentially only the differences from the embodiments according to FIGS. 1 to 5 are described here.

The cable arrangement 1 shown in FIG. 6 has the charging cable 2 , the guide device 5 and the guide device 6 . The guiding device 6 includes in particular the deflection module 7 and a plurality of cable carriers 8.

Three cable carriers 8 are shown here, it being provided that a different number of cable carriers 8 can be accommodated in the guide device 5 . The cable carriers 8 of the present exemplary embodiment have a shape similar to eyelets, with the cable carriers 8 being connected to the traction means 9 . The cable carrier 8 is designed to carry and/or support the charging cable 2 .

The exemplary embodiment shown in FIG. 6 differs in particular by the deflection module 7. In the present case, the deflection module 7 has three rollers 28, the rollers 28 being arranged in an arc of a circle. The deflection module 7, in particular the rollers 28, are designed to accommodate the charging cable 2. The charging cable 2 is preferably guided over the rollers 28 . In particular, the charging cable 2 slides over the rollers 28 of the deflection module 7.

The deflection module 7 preferably has a cover (not shown here). The cover is preferably arranged on one side of the charging cable 2 in each case, so that the charging cable 2 is supported by the cover on both sides. The cover of the deflection module 7 ensures better guidance of the charging cable 2 and a better hold.

The deflection module 7 has a bending radius. The bending radius of the deflection module can vary between 45 cm and 55 cm. The present exemplary embodiment is preferably suitable for the liquid-cooled charging cable 2 and the UL variants of the charging cable 2.

FIG. 7 shows a schematic representation of a parking arrangement 25. In particular, at least a part of a parking arrangement 25, in the present case in the form of a multi-story car park or parking garage, is shown schematically. The parking arrangement 25 has a large number of parking spaces 26 . The parking spaces 26 are designed for parking an electric vehicle 27 . The electric vehicle 27 can be embodied as an electric car, a bus, a truck, a scooter and/or a motorcycle. A majority of the parking spaces 26 have the cable assembly 1 . The cable assemblies 1 are arranged parallel to each other. In particular, the cable arrangements 1 are arranged parallel to one another on the ceiling 16 of the multi-storey car park above the respective parking space 26 .
