Description

Description Charging station The invention relates to a charging station for charging electric vehicles.

Charging stations for charging electric vehicles are sold, for example, by Siemens under the product name "Charge CP700A".

The invention has for its object to provide a charging station, which is particularly easy to assemble and wire.

This object is achieved by a charging station with the features of claim 1. Advantageous embodiments of the charging station according to the invention are specified in subclaims.

Thereafter, the invention provides that the loading station comprises a door on the inside of one component of the charging station is mounted indirectly or UNMIT ^¬ telbar at least that control the charging process, monitor or protect.

A significant advantage of the charging station according to the invention is that the inside of a door of the charging station is used as a carrier for at least one electrical component of the charging station. The inventive idea is that the door of the charging station in the open state is very easily accessible and therefore allows in a particularly simple manner, an assembly of electrical components and wiring of the corresponding components. It has been established inventor other that significantly reduced in an arrangement of electrical components on the inside of the door of the loading station of the wiring work ^¬ the can compare to charging stations in which all electrical components in or on the housing body (for examples play on the rear or side wall) of the charging station are arranged.

To be particularly advantageous, it is considered, if the one component is at least ^¬ arranged in a door portion which is free of openings or holes, and the door portion shields the component from exposure from the outside. An arrangement of the electrical components in door sections, which are free of openings or holes, it allows in a very advantageous manner, an assembly of compo ^¬ nents on rails, such as DIN rails. In addition, the electrical components are protected from external impact by the door in the closed state.

With a view to a particularly fast and inexpensive Mon day and wiring, it is considered advantageous if the at least one component of the charging station is mounted on a Trä ^¬ gereinheit, which is taken on the inside of the door fastened. In this embodiment, one or meh rere electrical components of the charging station outside the housing body and separated sepa rat from the door of the charging station preassembled, namely on the carrier unit, as well as there also wire. The preassembled and pre-wired unit consisting of the carrier unit and the electrical components of the charging station mounted thereon then only has to be connected to the door of the charging station during the final assembly, for example by hanging, screwing or otherwise. The carrier unit is preferably a mounting plate, a mounting frame or the like.

Since the directly or indirectly attached to the door electrical components of the loading station can comprise a non unerhebli ches weight, it will be seen to be advantageous ^¬ when the loading station has a door lifting device which lifts the door when closing.

A door lifting device makes it possible advantageously to slightly raise the door when closing and thus the caused by the electrical components mounted on the door weight force at least partly to kompensie ^¬ ren. sagging of the door and characterized evoked terminals when closing the door can thus be avoided in a very simple manner.

A particularly simple and therefore advantageous can be realized ^¬ a door lifting device when the door lifting means comprises a wedge which is mounted on the door and / or to the door frame. For example, mutually cooperating wedges may be provided both on the door and on the housing body of the charging station, which lift the door when closing. Alternatively, a wedge which is mounted on the housing body or on the door, cooperate with a roller which is mounted on the respective other part, ie the door or the housing body.

Preferably, the at least one component of Ladesta ^¬ tion, the control, monitor or protect the charging process can, one or more computing devices (eg. B. microprocessor means) that carries out the function of controlling, monitoring and / or protecting. Thus, at the at least one component comprises, in other words before ^¬ preferably a control and / or protection device comprising at least one microprocessor means.

Additionally or alternatively, one or more of the following components may be attached to the door: contactors (eg, one per charge outlet), fuses (eg, one per charge outlet), residual current circuit breaker (eg, one per charge outlet), current transformers (eg one per charge outlet), thermostats, rear part motors (eg for residual current circuit breakers or circuit breakers), switches (eg one per charging outlet), auxiliary contact switch (eg one per charging outlet), relays.

With a view to a particularly simple wiring, it is considered advantageous if at least 50% of the electrical components of the charging station directly or indirectly at the Door attached and wired. Particularly preferred ^¬ who the at least 70% of the electrical components mounted directly or indirectly on the door. The percentages of 50% or 70%, for example, refer to the weight, the volume or the respective wiring complexity (eg, related to the wiring time during assembly) of the components.

With regard to the connection of the charging station to an external power supply network, it is considered advantageous if an electrical interface module (with or without overload or short-circuit si) on a housing wall (eg side or rear wall) or the housing bottom of the charging station - insurance, for example in the form of a so-called house connection box) and / or an electrical energy meter is mounted. Both the electrical interface module and the energy meters are particularly preferred gehäusekör- perseitig, ie on the side wall, the rear wall or the Ge ^¬ housing bottom, is mounted.

In a particularly preferred embodiment of the charging station is provided that the electrical interface module and the electrical energy meter are mounted directly or indirectly on a housing wall or the housing bottom of the charging station and all other electrical components that ^fulfill a monitoring, control or protection function he ^¬ attached and wired on the door side. In this embodiment, all circuits relevant components with the exception of the electrical interface module, the electrical energy meter and the external charging ports can thus be wired and mounted door side, whereby the assembly and wiring costs is reduced to a minimum.

The invention also relates to a method for mounting and wiring a charging station. According to the invention, it is proposed in this regard that at least one component of the charging system be provided on the inside of a door of the charging station. Station is installed and wired, which can control, monitor or protect the charging process.

With regard to the advantages of the method according to the invention, reference is made to the above-described advantages of the charging station according to the invention, since the advantages of the charging station according to the invention essentially correspond to those of the method according to the invention. It is considered particularly advantageous in such a method if the at least one component of the charging station is fastened and wired on a carrier unit and the carrier unit with the component mounted thereon is attached to the inside of the door. As already mentioned, the installation effort is particularly low if the door-side electrical components of the charging station are pre-assembled and pre-wired on a separate carrier unit before the carrier unit is connected to the door, for example hung in the door.

The invention will be explained in more detail with reference to Ausführungsbeispie ^¬ len; thereby show by way of example

For the sake of clarity, the same reference numbers are always used in the figures for identical or comparable components.

FIG. 1 shows a charging station 10 whose outer surface is limited by a housing body 20 and a door 30. The housing body 20 comprises a housing bottom 21, two side walls 22 and 23 and a rear wall 24.

In the figure 1 it can be seen that both the right in the figure 1 sidewall 22 and the left in the figure 1 side wall 23 each having a charging terminal are 50 ^¬ equips. The charging ports 50 may be formed for example by sockets, in each of which a plug 51 of a charging cable not shown who can ^¬ the inserted. The charging connection 50 on the right in FIG. 1 can thus be connected to an electric vehicle via a charging cable in order to charge it.

For connecting the charging station 10 to an external electrical power supply network, the charging station 10 has a

Interface module 60, for example, rests on the housing bottom 21 of the housing body 20 and is in communication with the rear wall 24. With the ^{Schnittstellebau ¬} stone 60, which may be, for example, a house connection box or the like, is a counter 70 in connection, which measures the consumed by the charging station 10 for charging electrical energy.

The interface module 60 may be equipped, for example, with short-circuit fuses, around the charging station 10 safely disconnect from the power supply in case of a short circuit.

For controlling and monitoring the charging processes, the charging station 10 has a control device 80, which is preferably equipped with one or more computing devices (eg in the form of one or more microprocessor devices). The computing device (s) of the controller 80 control the charging process; Moreover, it is considered advantageous if the computing device (s) of the control device 80 additionally monitor the charging process and protect the charging station 10. The control device 80 thus represents a central component of the charging station 10. In addition to the control device 80, the charging station 10 is equipped with further electrical components, which are preferably all arranged directly or indirectly on the door 30. In the other electrical components, some of which are exemplarily designated by the reference numeral 90 in the figure 1, can be, for example, be fol ^¬ constricting components: contactors (. For example, a contactor for each charging outlet), fuses (eg. one fuse per charging outlet), residual current circuit breaker (eg one residual current circuit breaker per charging outlet), current transformers (eg one current transformer per charging outlet), thermostats, rear part motors (eg for one

Residual current circuit breaker or a circuit breaker), switch, auxiliary contact switch.

In addition, it can be seen in FIG. 1 that the further electrical components 90 as well as, for example, also the control device 80 are fastened to the door 30, preferably by means of rails, for example DIN rails 32. The arrangement of the components 80 and 90 is preferably carried out in door sections which are free of openings or holes. In this way it is ensured that the components are not accessible from the outside or are protected from an external influence. In the embodiment shown in Figure 1, the Steuerein ^¬ direction 80 and the other electrical components 90 are not mounted directly on the door 30, but medium ^¬ bar. For this purpose, a carrier unit 31 is provided, which carries the control device 80 and the further electrical components 90. Once the controller 80 and the other electrical components have been pre-mounted on the carrier unit 31, 90 and pre-wired, the Trä ^¬ gereinheit 31 is fixedly connected to the door 30, for example by screws, suspending or otherwise.

In the embodiment according to FIG. 1, the ^interface module 60 and the counter 70 are mounted in or on the housing body 20. This embodiment is considered to be advantageous, but it is only to be understood as an example. Alternatively, the interface module 60 and the counter 70 can be attached directly or indirectly to the door 30, if desired, for example, by the operator.

2 shows the charging station 10 in a view from the side, wherein the door 30 is shown in the open state. It can be seen the control device 80 and the other electrical components 90 which are attached to the support unit 31 and thus to the door 30. In addition, one recognizes the charging port 50, which is accessible on the side wall 22.

FIG. 3 shows the charging station 10 according to FIGS. 1 and 2 in a view from the front, the door 30 of the charging station 10 being open and protruding vertically out of the image plane. It can be seen that both the control device 80 and the further electrical components 90 in the opened state are very easily accessible and thus can be wired and / or exchanged in a very simple manner.

In addition, in FIG. 3, the two charging ports 50 are clearly visible, which are attached to the two side walls 22 and 23. In the illustration according to FIG. 3, FIG both charging ports 50 each have a plug 51 inserted, with each of which a charging cable not further shown is in communication. 4 shows a second embodiment of a charging station 10. The arrangement of the interface module 60, the counter 70, the control device 80 and the other electrical components 90 corresponds to the arrangement, as already explained in detail in connection with Figures 1 to 3 has been.

In contrast to the first exemplary embodiment according to FIGS. 1 to 3, in the exemplary embodiment according to FIG. 4 an additional door lifting device 100 is provided which comprises a door-side lifting element 110 and a housing-side (frame-side) lifting element 120.

When the door closed 30 and pivoted toward the housing body 20, so the door-side lifting member 110 will encounter the housing-side lifting member 120 and lift the door 30 low ^¬ fügig. Such lifting prevents the door 30 from being jammed or closed when, by the weight of the control device 80 and / or the further electrical components 90, the door hangs down so that it can not close properly by itself.

5 shows an exemplary embodiment of the Türhebeein ^¬ direction 100 and the two hoisting members 110 and 120 according to Figure 4 in further detail.

It can be seen that the door-side lifting element 110 comprises a roller 111 which is rotatably mounted about a pivot bearing 112 on a lifting support member 113. The lifting carrier part 113 is preferably by means of a

Screw attached to the door 30. The screw can be done for example via slots in the door 30, which allows an adjustment of the vertical height of the lifting support member 113 during the final assembly. Moreover, FIG. 5 shows in greater detail the design of the housing-side lifting element 120 mounted on the housing body 20. It can be seen that the term gehäusesei- lifting member 120 comprises a wedge 121 which is fixedly mounted on the housing body 20 of the charging station ^¬ 10th The arrangement of the lifting support member 113 and the roller 111 of the door-side lifting member 110 is selected such that upon closing the door 30, the roller 111 strikes the wedge 121 of the housing-side lifting member 120 and the door 30 is pushed upwards along the arrow direction P or is raised.

In the embodiment of the door lifting device 100 according to FIG. 5, a particularly low-force lifting of the door 30 is possible since the roller 111 can roll on the wedge 121 so that there is no sliding friction at the interface between the door-side lifting element 110 and the housing-side lifting element 120 is to overcome. As already mentioned, the assembly of the lifting carrier part 113 on the door 30 can provide a readjustment in the vertical direction in order to ensure optimum cooperation of the two lifting elements 110 and 120. Alternatively or additionally, it may be provided to manufacture the roller 111 from an elastic material, so that certain tolerances can be compensated by a compression of the roller material of the roller 111 when hitting the wedge 121.

6 shows a second embodiment for a door lifting device 100 for the loading station 10 according to FIG 4. In this embodiment, the housing-side Hebeele ^¬ element 120 includes a key 121, as has already been described in connection with FIG. 5 In contrast to the embodiment according to figure 5, however, the door-side lever element 110 is configured differently at the Ausführungsbei ^¬ game according to FIG. 6 As can be seen in the fi gure ^¬ 6, also includes the door-side lifting element 110 a wedge 114, the wedge surface 115 of which cooperates with the wedge 121 of the housing-side lifting element 120.

When the door 30 is closed, the wedge surface 115 of the wedge 114 is hit on the wedge 121, so that the door 30 ent ^¬ long direction of the arrow P is pushed up and raised when the door 30 - for example due to the high Ge ^¬ Weight of the control device 80 and the other electrical components 90 (see Figure 4) - sags and the wedge 114 hangs lower than is provided for an optimal position of the door 30 in the closed state of the charging station 10.

Although the invention has been further illustrated and described in detail by the preferred embodiments, the invention is not limited by the disclosed examples, and other variations can be derived therefrom by those skilled in the art without departing from the scope of the invention.
