DETAILED DESCRIPTION OF THE INVENTION

[0073] FIG. 1 shows a charging station 2 with a charging column 5. The charging column 5 comprises a charging column housing 7 in which a receptacle 2a is provided. The receptacle 2a of the charging column 5 is provided for receiving a charging device 3.

[0074] The charging device has a charging device housing 9 and is formed in a modular manner in the present case. According to the application only the charging device housing 9 of (from, respectively) the charging column housing 7 and the charging device housing 9 is completely sealed, in particular, with the protection class IP55 according to the standard DIN EN 60529, while the charging column housing 7 is not completely sealed.

[0075] In the present case, the charging device 3 is formed by a docking station 4 and a charging unit 6, each of comprise has a housing. The respective housings together form, at least in part, the charging device housing 9, as will be explained in more detail.

[0076] The docking station 4 can be fixed in the receptacle 2a, for example, screwed, as will be explained in more detail. An electrical connection (not shown) to a power supply network can be introduced into the docking station 4 via the charging station 2. The charging unit 6 may be assembled as a tub assembly and a cover assembly, which will be described in more detail below, and may be placed on the docking station 4 and electrically and mechanically fixed to the docking station 4.

[0077] Together with the mechanical fixation, the charging unit 6 may be electrically coupled to the docking station 4 via a plug/socket. A communication coupling may be provided via at least one patch cable between the docking station 4 and the charging unit 6.

[0078] In the installed state, the docking station 4 is completely received in the receptacle 2a and the charging unit 6 substantially completely surrounds the outer edge of the docking station 4 and is also at least partially recessed in the receptacle 2 with its side edges.

[0079] If necessary, however, the docking station 4 can also be mounted directly on a wall without the need for the charging column 2 with the receptacle 2a. In this case, too, the side walls of the docking station are at least partially enclosed by side walls of the charging unit 6.

[0080] As can be seen from FIG. 1, the base area of the docking station 4 and the charging unit 6 are approximately congruent with each other, so that when mounted and viewed from the front, the charging unit 6 completely covers the docking station 4.

[0081] The modular structure of the present embodiment of the docking station 4 and the charging unit 6 is shown in more detail in FIG. 2.

[0082] In FIG. 2, the docking station 4 is first shown, which comprises a cable entry 8, in particular, in the form of a cable gland 8, in a first circumferential side wall 10 of the docking station 4.

[0083] In particular, a detachable cable feed-through plate 25 is provided in a plate receptacle 23 corresponding thereto, which is arranged in the first circumferential side wall 10. The cable feed-through plate 25 may have a circumferential seal in its edge region. In the assembled state of the docking station 4, the cable feed-through plate 25 is held in a clamped in the plate receptacle 23, in particular, by the protective housing cover 12, so that a sufficient seal of the docking station 4 is provided by the seal and the sealing element, respectively, of the cable feed-through plate 25.

[0084] A housing cable opening may be established or be at least establishable in the cable feed-through plate 25 for a passage of the power connection cable. Inserting the power connection cable into the established housing cable opening may comprise mounting a cable gland 8 to the established housing cable opening. The cable gland 8 may fix the fed-through cable to the housing cable opening. In particular, the cable gland 8 comprises a sealing element to prevent water from entering.

[0085] The docking station 4 is at least partially closed by a protective housing cover 12 on the side facing the charging unit 6. Preferably, first recesses 14a, 14b and first openings 14a, 14b, respectively, are provided in the protective housing cover 12, which will be described in more detail below.

[0086] Preferably, the charging unit 6 may be formed by a tub assembly 20 and a cover assembly 26.

[0087] Openings 16 may be provided between the protective housing cover 12 and the first side wall 10. Through these openings 16, bars 18 of the tub assembly 20 can be inserted into the docking station 4 so that the tub assembly 20 can be fixed to the docking station 4 via the bars 18. In other words, the charging unit 6 can thereby be mechanically fixed to the docking station.

[0088] For this purpose, in particular, a locking module 41 in the form of a locking bracket 41 is fixedly integrated in the docking station 4. The locking bracket 41 can be moved between an open position, in which the bars 18 can be inserted into the recesses 16 to an end position, and a locking position, in which the locking bracket is positively fixed to the bars 18. In the locking position, the locking module 41 is locked to the bars 18 such that movement of the bars 18 out of the recesses (receptacles) 16 is blocked.

[0089] Furthermore, a circumferential sealing element 19 is provided, which is clamped in an assembled state of the charging device 3 and thus sealingly held between the first side wall 10 and the second circumferential side wall 13 of the charging unit 6. By being locked by the locking module 41, the sealing element 19 remains in the clamped position. This will be described in further detail below.

[0090] As previously explained, the tub assembly 20 can be coupled to the docking station 4. In the present embodiment, the tub assembly 20 is part of the charging unit 6, which also includes the cover assembly 26. The tub assembly 20 accommodates a power module 22 and a charging socket 24. The tub assembly 20 is substantially closed on the bottom side with a bottom, and is closed on the cover side by the cover assembly 26.

[0091] The circumferential second side wall 13 and the cover 11 of the cover assembly 26 preferably together with the first circumferential side wall 10 and the bottom 17 of the docking station 4 (substantially) form the charging device housing 9 of the charging device 3.

[0092] Via snap (latching) elements 28, the cover assembly 26 can preferably be fixed to snap (latching) elements 30 in the side walls of the tub assembly 20. In particular, a circumferential sealing element 21 may provide a sufficient seal in the fixed state of the cover assembly 26 with the tub assembly 20.

[0093] The cover assembly 26 may include a shutter 84 and control elements, such as a display 34.

[0094] In the joined and fixed state, respectively, the cover assembly 26 is mechanically joined to the tub assembly 20 and thus seals the tub assembly 20 on a top side. On a bottom side, the tub assembly 20 is joined to the docking station 4 and the previously described sealing between the docking station 4 and the tub assembly 20 is carried out via the at least one first circumferential side wall 10.

[0095] Between the cover assembly 26 and the tub assembly 20, a seal is made along the outer edge 21 formed as a sealing element facing the cover assembly 26.

[0096] The docking station 4 serves as a connection level and can be connected to a power supply network independently of the charging unit 6. As long as the charging unit 6 is not coupled to the docking station 4, the charging unit 6 is voltage-free. By coupling the charging unit 6 to the docking station 4, the charging unit 6 is connected to the power supply network. The charging unit 6 can be understood as a supply level, which comprises at least one charging technology module, comprising the charging technology, and other “intelligence”. This modular design makes it possible to first assemble the docking station 4 by a fitter qualified to do so, without the need to immediately assemble a charging unit 6.

[0097] The charging unit 6 can be coupled to the docking station 4 at any later time, even by a technical layman, in a particularly simple manner, mechanically without tools, which then automatically electrifies the charging unit 6. The charging unit 6 is particularly flexible and modular due to its special design consisting of a tub assembly 20 and a cover assembly 26, as explained previously, and can be coupled to the respective application.

[0098] The docking station 4 is shown in more detail in FIG. 3. The docking station 4 comprises a bottom 17 and at least one first circumferential side wall 10. A mains board 34 and an interface board 36 are arranged on the base 17 of the docking station 4. A connector strip 38 is provided on the mains board 34 for connecting a power supply cable, which can be inserted according to the above embodiments.

[0099] Scale bars 40 may be provided on the first side wall 10 and/or the bottom 17.

[0100] In addition to the connection strip 38, a first power connection 42 is also arranged on the mains board 34 as a socket.

[0101] Furthermore, a receptacle 44 is provided between the first circumferential side wall 10. The receptacle 44 is closable by a cover. A measuring device, for example, a smart meter or an iMS, can be anchored in the receptacle 44 in a snapped manner. Not shown are cable through-feeds (bushings) through the side walls of the receptacle 44 for wiring the measuring device. The receptacle 44 can be sealed via suitable holes, which is not shown in detail.

[0102] Connectors 46,48 are provided on the interface board 36 for a network cable and for a CAN bus and/or a GPIO bus. In addition, connector sockets may still be provided for connection to modules within the charging unit.

[0103] The external wiring with a local network is carried out via a connection strip, which can then be tapped via an RJ45 socket. In particular, sufficient contacts are provided here to connect at least two independent local networks. For example, a first local network can be formed with a central unit and a second local network between master and slave units, i.e. between a charging unit with a master controller with at least one, preferably several charging unit(s) with only one slave controller. The two local networks can be connected together via a single patch cable to the charging unit 6 and the modules arranged therein, respectively.

[0104] To install the docking station 4, it is first fixed mechanically either in the receptacle 2a or screwed to a wall, for example. For this purpose, as can be seen in FIG. 4a, the docking station 4 has at least one opening 15 in the bottom 17, in this case, in particular, three openings 15.

[0105] As can be seen in FIG. 4b, screws 27 can be inserted into the openings 15 to create a mounting connection, in particular, a screw connection, between the charging device 3, in particular, the docking station 4, and the receptacle 2a. Subsequently, a sealing plug 29 is placed on each opening 15 to cover these openings 15 in a sealing manner.

[0106] After the docking station 4 has been mounted in the receptacle 2a of the charging station 2, a multi-core power cable is introduced into the interior of the docking station 4, in particular, through the cable entry 8. This cable comprises, in particular, large cable cross-sections and a rigid cable core. Therefore, the cables are difficult to process. In order to ensure that the cables are always cut to the correct length, the fitter can place the cable against the scale 40 and cut it to length immediately. This allows the fitter to assemble the connection cable correctly so that he can place it on the connection strip 38 without any problems in the connection.

[0107] Depending on the assembly, a measuring device can be arranged in the receptacle 44. This measuring device is wired via flexible cables starting from the connection strip 38. Starting from the measuring device, wiring is again carried out via flexible cables to a power connection 42. If no measuring device is installed, wiring is carried out directly via a flexible cable between the connection strip 38 and the power connection 42. A connection strip for receiving the respective cables is also provided at the power connection 42.

[0108] A network cable and data cable, respectively, can also be inserted into the housing of the docking station 4 via the cable entry 8 and applied to the connections 48.

[0109] After the electrical wiring of the docking station 4 has been carried out, the housing of the docking station 4 is closed by a protective housing cover 12, as shown in FIG. 4.

[0110] In FIG. 4, it can be seen that the protective housing cover 12 comprises, in addition to the recess 14a for the first power connector 42, at least one further first recess 14b for the communication connectors of the interface board 36, in particular, an RJ45 connector as well as a GPIO connector and a CAN bus connector. Through the RJ45 connector 46, an RJ45 connector can accommodate a connection to two separate LAN networks. A power connection to the charging unit 6 can be established through the first recess 14a, and a data connection to the charging unit can be established through the further first recess 14b.

[0111] Openings 16 are provided on the side edges of the protective housing cover 12. The openings 16 are located between the cover 12 and the side wall 10 of the docking station 4. Through the openings 16, the bars 18 of the tub assembly 20 can be inserted into the docking station 4 so that these bars 18 are completely received by the side wall 10 of the docking station 4. Thus, the charging unit 6 can be mechanically anchored within the docking station 4 by the tub assembly 20, as previously described.

[0112] After the docking station 4 has been installed in the manner shown, the docking station 4 may remain initially unequipped, protected by the protective housing cover 12, and may be equipped at any later time with a charging unit 6 having a tub assembly 20 and cover assembly 26.

[0113] A tub assembly 20 is shown in one equipment variant in FIG. 5 as an example.

[0114] The tub assembly 20 comprises a housing with at least a second circumferential side wall 13 and a bottom 20b. In the region of the second side wall 13, respectively of the bottom 20b, a power module 50 can be mechanically anchored on the bottom side in the tub assembly 20 as a charging technology module 50.

[0115] In the present embodiment, the power module 50 comprises a charging port 52 and a charging control circuit 54. On the bottom side of the power module 50, as also shown in FIG. 5, a second power connector 56 is arranged in the form of a plug 56 corresponding to the socket of the first power connector 42.

[0116] A collar 58 is arranged circumferentially around the plug 56. The collar 58 is facing away from the surface of the circuit board of the power module 50. In particular, the collar 58 comprises an extension in this direction that is greater than the longest extension of any contact of the plug 56.

[0117] Further components for power monitoring and/or power control are provided on the power module 50. In addition, a connector 60 for a communication bus is disposed on the power module 50.

[0118] The communication bus connector 60 allows the communication bus to be connected to the power module 50. In a plug and play manner, the communication bus can receive and connect both a communication module and a user interface module, which will be described further below, to the power module 50. This makes it possible to add modules to the power module 50 by means of the communication module and/or the user interface module, in order to be able to adapt the charging unit 6 to the respective requirements as needed.

[0119] The power module 50 is arranged in a first region of the bottom 20b. A fixing means 62 is provided in a second region of the bottom 20b, which fixing means 62 is formed from flanges arranged in a comb-like manner with openings aligned with one another.

[0120] The fixing means 62 is formed of two opposing comb-like structures, which enclose an opening 64 in the bottom 20b. The fixing means 62 correspond to the fixing means 66 of a receptacle body 68 for a charging bushing 70. In the assembled state, the charging bushing 70 is arranged directly above the opening 64. Through the opening 64, it is possible to perform a manual emergency release on the charging bushing 70 from the bottom side of the tub assembly 20, through the bottom 20b.

[0121] In order to mount the receptacle body 68 to the tub assembly 20, the mounting body 68 is aligned with its fixing means 66 with respect to the fixing means 62 such that pins 72 can be pushed through the aligned openings. As a result, the pins 72 secure the mounting body 68 to the housing of the tub assembly 20.

[0122] In a partially assembled state, the power module 50 is inserted in the bottom of the tub assembly 20, as exemplified shown by FIG. 6. Here, the connector 56 including the collar 58 is inserted through the second opening 74 on the bottom side (which corresponds to the first opening 14a).

[0123] The power module 50 is mechanically snapped with the housing of the tub assembly 20, and may be mounted in a floating manner therein. Alternatively or commutatively, the mains board 34 may be mounted in a floated manner within the housing of the docking station 4. The floating mounting has the advantage that, when the tub assembly 20 is mounted on the docking station 4, the connector 56 and the second power connector 56, respectively, can independently align itself with the socket of the first power connector 42. This increases ease of use, particularly facilitating assembly by a layperson.

[0124] The bottom side of the tub assembly 20 is shown by way of example in FIG. 7. It can be seen that the bars 18 project away from the bottom 20b of the tub assembly 20. Further, the collar 58 with the plug 56 can be seen protruding through the second opening 74. There can be provided further second openings, for example, to provide a data connection between the docking station 4 and the charging unit 6.

[0125] The collar 58 comes into engagement with the opening 14a in the assembled state. In the opening 14a, as can be seen in FIG. 4, an annular gap 74 is formed between the socket of the first power connector 42 and a collar 78 projecting into the interior of the housing of the docking station 4. The collar 78 provides contact protection for the docking station 4.

[0126] During the assembly, the tub assembly 20 is placed on the docking station 4 and, as can be seen from the combination of FIGS. 4 and 7, the collar 58 slides into the annular gap 76. The collar 58 enters the annular gap 76 before a contact of the connector 56 comes into electrical contact with a contact of the socket of the first power connector 42. This prevents an electric shock from occurring when the tub assembly 20 is mounted to the docking station 4.

[0127] The receptacle body 68 is such that it is configured to receive a wide variety of charging sockets 70, or in other words, a wide variety of charging sockets 70 may be provided with different receptacle bodies 68, wherein in each case the fixing means 66 is at the same distance from one another and thus forming a uniform mechanical interface with the fixing means 62. This results in a wide variety of charging sockets 70 being able to be installed in one and the same tub assembly 20, as can be seen by way of example from FIGS. 8a-c.

[0128] There it can be seen that the fixing means 62, 64 engage in one another and are mechanically locked together via the pins 72. FIG. 8a shows a receptacle 68 with a CCS charging socket 70, FIG. 8b shows a receptacle 68 with a Chademo charging socket 70 and FIG. 8c shows a receptacle 68 with a Type2 charging socket 70.

[0129] As can be seen in FIGS. 8a-c, the receptacle body 68 makes it possible to accommodate a wide variety of charging sockets 70 without having to make a design change to the housing of the tub assembly 20.

[0130] The charging sockets 70 do not necessarily have to be electrically connected to the charging port 52, but may remain potential free. In this case, the charging sockets 70 may serve as a “plug garage”. The charging outlet 52 may be electrically connected to a charging cable fixedly attached to the housing of the tub assembly 20. The charging cable may exit in the region of a recess 80 in the side wall of the tub assembly 20.

[0131] If a permanently attached cable is not used, the charging receptacle 70 may be electrically connected to the charging control circuit 54 via the charging port 52. The charging port 52 has three connections for one phase each on one terminal strip, a further terminal strip with two connections for the neutral conductor and the protective conductor and, if necessary, a connection socket for a plug present (PP) contact and a pilot conductor (CP) contact.

[0132] In order to install the charging socket 70, the receptacle body 68 is arranged on the tub assembly 20, the charging socket 70 is connected to the respective terminals of the charging outlet 52 via pre-assembled cables, and then the receptacle body 68 is fixed in the tub assembly 20 via the pins 72.

[0133] In addition to the tub assembly 20, the charging unit 6 also comprises the cover assembly 26 with the cover 11, as shown in FIG. 9 by way of example.

[0134] The top side of the cover assembly 26 may comprise a variety of control elements 82 and/or a shutter 84 on a top surface. At the side of the cover assembly 26, snap elements 86 may preferably be provided on the side edges thereof and may engage the inner second circumferential side wall of the tub assembly 20. This allows the cover assembly 26 to be mounted on the tub assembly 20, as described above.

[0135] The snap elements 86 may be configured such that they snap to the second sidewall of the tub assembly 20 and, in particular, can be non-destructively disengaged only when disengaged from the bottom side, starting from the bottom 20b of the tub assembly 20. This prevents the cover assembly 26 from being disengaged from the tub assembly 20 while the tub assembly 20 is still electrically connected to the mains board 34 of the docking station 4.

[0136] At the rear side of the cover assembly 26, as shown in FIG. 10, the shutter 84 is supported so that it can be moved in a direction of movement 88 to release the charging port 70. As shown by way of example in FIG. 11, the shutter 84 is spring-loaded by a spring 98 so that it automatically moves to the closed position shown.

[0137] A communication module 90 and a user interface module 92 may be disposed in a further portion of the cover assembly 26. The communication module 90 as well as the user interface module 92 may be mechanically fixed to the cover assembly 26 and its housing, respectively.

[0138] The communication module 90 is connected to the power module 50 and the user interface module 92 via the communication bus.

[0139] The communication module 90 comprises a charging control circuit, not shown in detail here, that has electrical access to the charging port 52. The charge control circuit may override, or at least be coupled to, the charge control circuit 54 so that the two charge control circuits may coordinate a control of a charging process.

[0140] FIG. 11 shows the arrangement of the communication module 90 as well as the user interface module 92 in the cover assembly 26. The user interface module 92 faces the inner side of the cover wall and is mechanically connected to the housing of the cover assembly 26 via click connections 94. The communication module 90, in turn, is also connected to the housing of the cover assembly 26 via connections not shown in detail.

[0141] The user interface module 92 is stationary with respect to the inner side of the cover assembly 26, such that precise positioning of sensors and signaling devices on the user interface module 92 with respect to the top side of the cover assembly 26 is assured. In particular, a display % may be optionally disposed within the cover assembly 26 and controlled by the user interface module 92 and/or the communication module 90.

[0142] FIG. 12 shows a schematic view of a charging station 2 according to the present application. The charging station comprises a charging column 5 with a charging column housing 7 which is not completely sealed. In the present case, the charging column housing 7 of the charging column 5 has a respective receptacle 2a for a respective charging device 3 on two opposing front surfaces.

[0143] Each charging device 3 again has a fully sealed, in particular, to IP55, charging device housing. In order to arrange further electrical components in the charging column, if required, a sealed distribution box 33 can preferably be arranged in the charging column housing 7.

[0144] FIG. 13 shows a schematic view of a further embodiment of a charging station 2. The charging station 2 comprises a charging column housing 7 which is not completely sealed. Furthermore, charging devices 3 are mounted in receptacles 2a.
