Abstract

The invention relates to a charging unit, comprising a main body, a housing at least partially extending around the main body, and a display device for displaying a status, which display device is visible at least on an end face of the housing.

Description

 Charging unit with display device

 Field of the invention

 The subject matter relates to a charging unit (charging unit, CU for short) which can be integrated into different charging infrastructure solutions (for example charging station or charging box) for charging electric vehicles with the features according to the preamble of claim 1.

Background of the invention

 Charging stations for recharging electric vehicles are usually located at home or in the home of users of electric vehicles (e.g., in their garage), at work or at publicly accessible car parks

To charge electric vehicles. Such charging boxes can be installed, for example, on a wall, charging stations can be mounted, for example, free-standing on the floor. To facilitate charging of electric vehicles, charging boxes are electrically connected to an energy source (e.g.

 Home connection or a station providing access to a power grid).

In addition to the charging of electrically connected to the charging infrastructure solutions electric vehicles can also be charged with these batteries that are not arranged in an electric vehicle during charging, such as backup batteries or the like.

Often such charging infrastructure solutions are installed in places where it is relatively dark (e.g., in a garage). Handling for one

Owners or users of an electric vehicle can sometimes be difficult, for. B. is an optical status of the charging station or charging box can not be seen. In the case of publicly accessible charging stations, it is often not possible to detect remotely if there is a charging station is free to connect an electric vehicle or not. Due to the charging cable, which may for example have a length of about 5 m, sometimes a parked directly in front of the charging station vehicle is not a clear indication of a busy charging station.

General description of some exemplary embodiments of the invention

 For example, in order to be able to inexpensively eliminate defects in the user interface used for the charging infrastructure solution, provision can be made for releasably arranging a charging unit comprising this user interface on the charging station. In the area of publicly accessible charging stations, such a charging unit can also be arranged non-detachably on the charging station or can be encompassed by it. Against the background of the prior art presented, the object of the invention is to provide a user-friendly charging unit, which simplifies the handling of the charging infrastructure solution by an owner or user of an electric vehicle. This object is objectively achieved in that the charging unit comprises at least one proximity sensor and at least one brightness sensor, wherein the proximity sensor detects objects in the region of the outside of the housing, and wherein the brightness sensor detects a brightness and / or darkness in the region of the outside of the housing.

It has been recognized that in a main body of the charging unit, the essential technique for controlling the charging unit and / or charging box (e.g.

Control circuit, user interface, input / output means) may be installed.

For example, a keyboard or the like may be provided as input means. As an output means, for example, a display or the like may be provided, so that an interaction with an owner or user of an electric vehicle is possible. Also conceivable is a combined input / output interface, for example a touch-sensitive display, which can display information as well as receive input from the owner or user.

A charging infrastructure solution in the sense of the present subject matter may be understood as a charging point at the location where an electric vehicle owner or user connects (e.g.

For the purposes of the present subject matter, a charging unit (also referred to as CU in this specification) can be understood, for example, as a replaceable element which can be arranged on a charging infrastructure solution (for example detachably) and has the means according to the invention. The

Loading unit is thus in particular after the nature of a module on a

 Charging infrastructure solution (eg a charging box, or charging station) can be arranged, detached and therefore exchangeable. Accordingly, in the case of a defect in a means included in the charging unit, only the charging unit needs to be exchanged, and in particular not the charging infrastructure solution. Alternatively, such a charging unit may be included in a charging station or charging box. In particular, in this case, the charging unit can be arranged so firmly on the charging station or charging box, so that in particular a release of the charging unit from outside the charging station or charging box is not possible. Alternatively, the charging unit can be arranged undetachably on the charging station or the charging box.

The proximity sensor can be arranged on the main body of the charging unit. This can be understood in the sense of the article that the

Proximity sensor is arranged in the region of the lateral surface of the base body. However, the proximity sensor can also be partially arranged in the base body. Preferably, the proximity sensor is arranged on one of the inside of the housing facing side of the base body. In particular, the Proximity sensor arranged on an outer circumferential surface of the base body. The arrangement of the proximity sensor is designed so that the proximity sensor

Objects in the region of the outside of the housing preferably detected without contact. In the event that the proximity sensor is arranged on the base body, the housing is, for example, at least partially transparent; in particular, the housing may be transparent at least in the region covering the proximity sensor. In this way it can be ensured, depending on the functional principle of the proximity sensor, that objects in the region of the outside of the housing can be detected by the proximity sensor.

Alternatively or additionally [in the case of several proximity sensors] is the

Proximity sensor arranged on the housing and electrically conductively connected to the base body. In particular, the proximity sensor may in this case be arranged, for example, on one of the outer sides of the housing.

Furthermore, the charging unit comprises a brightness sensor for detecting darkness and / or brightness. The brightness sensor is, for example, a sensor that can convert incident light into an electrical signal. For example, the brightness sensor is an optoelectronic sensor. The brightness sensor can also be arranged, for example, on the base body of the charging unit. Information acquired by the brightness sensor can be sent to a

Control circuit be transmitted. Additionally or alternatively, the

Brightness sensor, for example, from the base body of a charging station or a charging box and be connected to the main body of the charging unit so that in particular from the brightness sensor detected information from this to an entity (e.g., a control circuit) of the charging unit can be transmitted.

For example, one or more functions of the charging unit can be controlled and / or regulated on the basis of the information detected by the brightness sensor.

For example, by means of the brightness sensor, the display device for illuminating the environment can only be turned on when the S

 Brightness sensor detects information indicative of the presence of

Darkness is in the vicinity of the brightness sensor. This increases the

Energy efficiency, since the display device is only turned on, if this is actually required. The brightness sensor can, for example

Capture brightness information, where the brightness information is indicative of ambient brightness and / or ambient light color. Under environment is understood in particular the region of the outside of the housing of the charging unit.

 Additionally, the loading unit may include one or more other optional sensors. The one or more further sensors may, for example, be further proximity sensors and / or brightness sensors. The one or more other sensors may include, for example, biometric sensors (eg.

Fingerprint sensor) to z. B. an owner or user of one

Identify and authenticate electric vehicles. This can for example be ensured that only authorized persons z. B. start a charge, control or the like can. The one or more further sensors can, for example, stimulus sensors of the environment of

Be charging unit. By means of a stimulus sensor, for example, a temperature, a volume, and / or a humidity in the region of the surroundings of the charging unit can be detected. For example, the display device may be controlled and / or regulated based at least in part on information acquired by the stimulus sensor. For example, according to the temperature

Indicator light brighter or darker.

Further, for example, based on a volume that prevails in the environment of the charging unit, information to the owner or user of a

Electric vehicle can be signaled or not. For example, in a quiet environment, the charging unit may be controlled such that no sounds or the like (eg, to confirm successful entry of information for example, by means of a user interface of the charging unit). Such control of the charging unit may additionally or alternatively be based on the information detected by the brightness sensor. For example, information captured by the brightness sensor may be indicative of a

Darkness of the environment of the charging unit (eg at night). For example, in order not to disturb other persons (eg local residents), a reproduction of sounds by the charging unit can be dispensed with at night.

Based on a moisture information example, the

Display device controlled and / or regulated. For example, during rain, sometimes the reproduction of information by the display device may be changed, such as changing the intensity of the light reproduced by the display device. Additionally or alternatively, for example, a charging power detected by a stimulus sensor can control and / or regulate the display device. For example, at a high charging power with which an electric vehicle connected to a charging unit is charged, the color, intensity or the like of light of the display device may be changed. For example, additionally or alternatively depending on an owner or user of an electric vehicle and / or an owner of the charging unit, the appearance of the charging unit by a corresponding

Change of the light reproduced by the display device (for example, depending on the owner of an electric vehicle connected to the charging unit, the color of the light of the display device is changed). The corresponding information can for example be stored in a database. For example, an owner or a user of an electric vehicle and / or an owner of the charging unit may be identified on the basis of an identification information, and in the database, a corresponding one of the identification information

Control information for changing the appearance of the loading unit deposited. The main body can be solved in an exemplary embodiment releasably with a

Base body of a charging station or charging box be connected, so that the charging unit can be arranged on the charging station or the charging box. The base body of the charging station or the charging box can in particular be arranged fixedly (for example immovably). Of the

Base body can be arranged for example in a garage or a garage wall, as it is z. B. in a loading box is the case. By the base body is detachably connected to the base body, the main body is in particular interchangeable. This also allows the interchangeability of the main body comprehensive charging unit. For example, if a defect on a means of the loading unit (e.g.

Display device), therefore, only the charging unit including the defective means needs to be replaced.

The term "objects" in the sense of the present subject matter may be understood as including both things and people.

For example, as a user of the charging unit, a person may approach them, and this is accordingly detected by the proximity sensor. Further, for example, an electric vehicle may approach the charging unit, and this will

detected accordingly by the proximity sensor. The proximity sensor may be configured either exclusively of things or people as well

To capture objects. Alternatively, the proximity sensor may also be configured to detect things as well as people as well as objects.

By means of the display device for indicating a status (e.g., the charging unit and / or charging station and / or electric vehicles connected thereto), the information relevant to and charged to an electric vehicle can be displayed. In addition, the display device may have one or more other status information, e.g. a charging station and / or a charging unit and / or play with these connected electric vehicles. The display device may be, for example, for (i) optical, (ii) acoustic, (iii) haptic or (iv) a

Combination thereof, reproduction of information (eg according to the Information comprehensive and generated by a control circuit

Control information).

If, for example, an object is detected outside the housing, this can be represented, for example, by a status. For example, the display device can be switched on so that it lights up and, for example, illuminates the surroundings of the charging unit. Such a switched on

Display device of the charging unit may then provide, for example, an orientation to an owner or user to facilitate a possible charging of an electric vehicle.

For example, the battery condition of a connected battery (e.g., an electric vehicle) may represent a status. For example, the

Display device indicate the existing capacity of a connected battery or the like as a status. Alternatively or additionally, one of the

Load unit performed represent a status of the loading unit.

For example, it may be reproduced by means of the display device (e.g., optically) that a charging of a battery is in progress, or a started charging of a battery has been completed, and / or an error of the charging unit or an error in charging a battery has occurred.

Furthermore, for example, an occupancy of the charging unit a status

represent. For example, by means of the display device of an information indicative of a free or occupied loading unit can be played. Further examples of one or more statuses are conceivable. The examples given above are non-limiting of the subject matter.

An exemplary embodiment provides that the proximity sensor can detect metallic and non-metallic objects capacitively. Objects in the vicinity of the proximity sensor change the electric field between the proximity sensor and the earth's field. This change in the electric field can be caused by the Proximity sensor are evaluated, so that corresponding objects can be detected in the area of the outside of the housing.

A further exemplary embodiment provides that the proximity sensor detects a movement of objects in the region of the outside of the housing. In addition to detecting whether objects are near the proximity sensor, the

Proximity sensor also detect whether a movement of objects takes place or has taken place. A movement of objects can be from the

Proximity sensor, for example, be detected as information.

When using multiple proximity sensors, it is possible by a

Difference method to detect movements with respect to their direction of movement along at least one axis between the proximity sensors. This allows a movement along at least one axis by at least two

Proximity sensors are detected.

In an exemplary embodiment, the proximity sensor is a radar

Temperature, or an ultrasonic sensor. For example, a radar sensor emits focused electromagnetic waves and receives those of the emitted electromagnetic waves that are reflected from one or more objects. From the received waves reflected by at least one object, the following information can be obtained, among other things:

(i) the angle or direction to the object;

 (ii) the distance to the object (e.g., determined from the time shift

 between transmission and reception of the electromagnetic waves);

 (iii) the relative movement between the radar sensor and the object;

 (iv) the distance and the absolute speed of the object (e.g.

 determined from several individual measurements);

(v) a combination thereof. A temperature sensor can be, for example, a pyrometer or a thermal imaging camera, which can each detect, without contact, a heat radiation emitted by one or more objects.

For example, dynamic and / or electrostatic loudspeakers and, in particular, piezo loudspeakers, that is to say, are suitable for generating the (ultra) sound pulses (for example in air).

Membrane-coupled plates of piezoelectric ceramic, which are excited by reversal of the piezo effect to vibrate.

A further exemplary embodiment provides that the display device is arranged on the base body and the housing at least in which the

Display device covering area is at least partially transparent.

In this way it can be ensured, for example, that information reproduced by the display device is visible from the outside (for example from an owner or user of an electric vehicle).

A further embodiment is characterized in that the display device comprises at least one optical waveguide. The optical waveguide is, for example, a light tube. The optical waveguide is for example made of a (highly) transparent polycarbonate. In addition, one or more decoupling elements (eg microprisms or diffusers) may be arranged in a cavity formed by the at least one optical waveguide, so that light can exit from the optical waveguide via the decoupling elements. The optical waveguide can, for example, for decoupling introduced into the optical waveguide light outcoupling elements, which direct a portion of the light flux to the outside. For example, light from the cavity can exit the optical waveguide via the (highly) transparent polycarbonate. For example, a light source initiates light into the optical waveguide (light is emitted from the light source), and the outcoupling elements (eg microprisms) break this light so that at the location of the outcoupling element in the cavity of the optical waveguide

Optical waveguide can escape the light introduced. Accordingly, the light is visible at this point of the optical waveguide from the outside.

A further exemplary embodiment provides that the display device comprises at least one light source which can emit or introduce a light into an end of the at least one optical waveguide. The light source is, for example, a light emitting diode (LED, also

 Called light emitting diode). Alternatively, the light source is, for example, an organic light emitting diode (OLED), which is e.g. consists of organic semiconducting materials. For example, an LED driver may precede the LED or OLED (e.g., an LED driver of about three to four watts in power). The LED driver can be arranged, for example, on the base body. Alternatively, the light source is, for example, a laser light source. For example, a laser light source generates electromagnetic waves of high intensity and sharp focusing of the light (also referred to as laser beams). The display device may further comprise, for example, a light modulation means which is connected to the light source such that one of the

Modulated modulation of a light from the light source modulated into the optical waveguide (e.g., emitted). By a modulation of the light emitted by the light source can

For example, with only one light source different light signals in the Fiber optic cables are initiated. For example, the different light signals may be sequentially introduced into the optical waveguide at such a frequency from the light source that due to the frequency for a human observer, the effect arises that the different light signals are emitted simultaneously into the optical waveguide.

A further exemplary embodiment provides that in a first region of the optical waveguide, which faces the light source, a lower number of outcoupling elements are arranged in comparison to a second region of the optical waveguide, which is farther from the light source than the first region.

In particular, in order to enable a uniform emission of light via the outcoupling elements (eg microprisms) out of the optical waveguide, fewer, for example, closer to the light source that introduces the light

Decoupling elements may be arranged as in the second region, which is farther from the light source. Due to the arranged decoupling elements within the optical waveguide, a plurality of refractions of light, which are subject to the introduced light. Every break of light through one of the

Decoupling reduces, for example, the intensity of the introduced light. Consequently, in the area farthest from the light source

Fiber optic an equal intensity of the output via the coupling elements

To reach leaked light from the optical waveguide as in the area closer to the light source, more outcoupling elements can be arranged in this area. The first area has a smaller absolute number of decoupling elements compared to the second area. In the first area, the decoupling elements are arranged less densely (number of decoupling elements per area) than in the second area.

In an exemplary embodiment, the at least one optical waveguide is subdivided into at least two segments, wherein in each case information diverging from each other can be reproduced, in particular by means of the at least two segments. The at least two segments may, for example, be identical to the first region and the second region of the optical waveguide. The display device can be, for example, a multi-segment display device, ie the display device has, for example, a plurality of different segments (eg sections). For example, the optical waveguide of the display device in different areas may each be illuminated differently from each other to such a multi-segment display device to

enable.

In particular, different information about the at least two segments can be reproduced at the same time. For example, in a first segment, information can be indicative of a status of a battery connected to the charging unit, and another in a second segment

 Information indicative of a status of the loading unit. For example, the first segment may indicate that the battery is being charged, and the second segment may indicate that the charging station is currently busy. Furthermore, a plurality of segments may be provided. For example, each of these segments may represent a percentage of the charge status of a battery or the like. In the event that the display device is formed, for example, as the housing encircling light ring, for example, according to a state of charge of a battery connected to the charging unit percentage of this state of charge can be represented by a corresponding illumination of the segments. For example, in a charging state where a connected battery is 70% charged, the segments illuminate 70% of the area of the area

Display device. A further exemplary embodiment provides that the at least two segments of the display device differ from each other as light information represent. For example, a first segment may be "switched on", so that light emerges from this region of the optical waveguide .A second segment may be simultaneously "switched off", so that no light emerges from this region of the optical waveguide. Furthermore, both segments can be turned on, for example, the first segment in a first color (eg red) lights, and the second segment in a second color (eg green) lights.

For example, the at least two segments may represent light diverging from each other substantially simultaneously. At the same time in the sense of the subject matter may comprise a sequential display of divergent light, which is displayed sequentially and alternately in the at least two segments, but shown as simultaneous to a human observer

is perceptible. For example, this can be achieved if the light in the at least two segments each changes at a frequency of at least 25 Hz.

In an exemplary embodiment, at least one of the following parameters of the light emitted by the light source is adjustable into the optical waveguide:

(i) light temperature;

(ii) brightness;

 (iii) color;

 (iv) intensity;

 (v) frequency;

 (vi) or a combination thereof.

The light temperature can be specified, for example, in Kelvin.

The brightness may be, for example, a percentage, for example, 100% of the maximum possible brightness of the light source from the light source

Optical fiber introduced light corresponds. At 0% no light from the light source is introduced into the optical waveguide and corresponds to one deactivated light source. Values between 0% and 100% can correspond to a dimmed light, for example. The display device can be dimmable, for example, via this parameter. For example, the color may include an RGB value or the like so that the light source is lit in the color corresponding to the RGB value.

The intensity may be, for example, a percentage, for example, 100% of the maximum possible intensity of the light source in the

Optical fiber introduced light corresponds. At 0%, no light at all from the light source is introduced into the optical waveguide and corresponds to a deactivated light source. Values between 0% and 100% may, for example, correspond to a reduced intensity of the maximum possible light provided by the light source.

The frequency can be specified in Hz, for example, and adjusted for example by means of a light modulation means. For example, the frequency may be used so that the light source may be two or more different

Represents light signals.

A further exemplary embodiment provides that the base body a

Control circuit comprises, which detects one or more signals from the at least one proximity sensor and / or the at least one brightness sensor and / or a battery connected to the charging unit (eg an electric vehicle) and at least partially based on the detected one or more signals control information for the Display device generated.

The control circuit is arranged in the base body, for example, for evaluating the measured values detected by the at least one proximity sensor. The control circuit evaluates correspondingly detected signals from at least the

Proximity sensor off. In addition, the control circuit can receive signals from one or more several other sensors (eg brightness sensor) and / or with the

Evaluate the charging unit and / or batteries connected to the charging station. Subsequently, the control circuit may generate control information (e.g., a control signal) based on which the display device is driven. In an exemplary embodiment, the display device according to the generated

Control information information again.

The control circuit can also be partially arranged outside the housing of the charging unit, for example in the form of a central control of a

Home automation system. In this case, the detection of the information (for example signals) of the proximity sensor and / or the brightness sensor and / or the further sensors in the control circuit can take place, the evaluation of the acquired information and the derivation of control information therefrom can, for example, for the display device outside the loading unit. In particular on the basis of the derived control information, the light source initiates light into the optical waveguide in accordance with the generated control information. In the event that the control circuit generates a plurality of control information, the light source may, for example, initiate light into the optical waveguide in accordance with the generated plurality of control information.

In one embodiment, the control circuit generates upon detection of

Objects by the at least one proximity sensor control information indicative of activation of the display device. Accordingly

For example, the light source can be turned on so that over the

Output coupling light emerges from the optical waveguide. Another

Exemplary embodiment provides that the control information at least partially comprises a parameter for adjusting the light emitted by the light source. Does the control information include one or more such parameters as (i) light temperature; (ii) brightness; (iii) color; (iv) intensity; (v) frequency; (vi) or a combination thereof, the light source may introduce light into the optical fiber in accordance with these one or more parameters. In an example embodiment, the control circuit generates control information indicative of activation and / or adjustment of the display device based at least in part on brightness information acquired by the at least one brightness sensor. For example, the

 Display device in response to an external value of light in the region of the outside of the housing of the charging unit by means of a correspondingly generated control information adjustable. For example, the brightness of the

Display (eg, emitted light) may be increased in a (eg, very) bright environment of the charging unit, so that the information reproduced by the display device (eg, emitted light) is visible, despite the bright surroundings; . remains. Further, for example, the brightness of the information displayed by the display device (eg, emitted light) may be changed in an environment in which the ambient light has a specific light temperature (eg, substantially as blue-perceived light) displayed by the display device fjz. B.

emitted light) is visible or remains.

 An exemplary embodiment provides that, in response to a signal indicative of a status of a battery connected to the charging unit, the control circuit indicative of a status corresponding to a status for a

 Status information generated. For example, based at least in part on the control information indicative of status information of the loading unit

Display device reproduce the corresponding information. In the event that the charging unit has at least two proximity sensors, the control circuit can evaluate the detected information (eg signals) of at least two proximity sensors. This allows the detection of at least two objects in the region of the outside of the housing simultaneously. In an exemplary embodiment, the display device comprises a diffuser for the uniform discharge of light. The diffuser is arranged, for example, on the optical waveguide and this at least partially covering. Light emitted from the light source into the optical waveguide exits, for example, via the decoupling elements

Fiber optic, then hits the diffuser, which scatters the incoming light evenly. Alternatively, the diffuser, for example, the

Display device covering area of the housing, or be covered by this area of the housing. A further exemplary embodiment provides that the light source in

 Depending on a predetermined aging curve, the intensity of the emitted light varies. The aging curve reflects the aging of the light source, and in particular the brightness and intensity of light emitted by the light source decreases with aging (e.g., by the operation of the light source). For example, to keep the intensity of the light emitted by the light source identical over time, an aging curve can be used. For example, the aging curve causes the intensity and / or brightness of the light emitted by the light source to be increased or decreased. In an exemplary embodiment, the at least one optical waveguide is arranged on the base body such that the optical waveguide at least partially surrounds the outer edge of the housing.

This allows a visually appealing design of the housing, as the

Display device such as a housing circulating light ring acts. For example, the shape of this light ring may be substantially round. Alternatively, the shape of this light ring may be, for example, circular. The shape of the light ring may, for example, be rectangular or square in the event that the housing has a corresponding shape. Alternatively, the optical waveguide may be arranged deviating so that the display device as within a surface of the Housing arranged appears. The optical waveguide can, for example

be arranged in a strip on the base body.

Detailed Description of Some Exemplary Embodiments of the Invention The present subject matter will be described below by way of example

Embodiments described.

Fig. 1 shows a view of a section of a charging station 100 after one

Embodiment.

The charging station 100 comprises a base body 110, to which a detachably

Loading unit 120, also referred to as a so-called charging unit, is arranged. The loading unit 120 comprises a base body 150, which in Fig. 1 of a

Base body 150 at least partially enclosing housing 160 is covered. The loading unit 120 further includes a user interface 141, a

Proximity sensor 142, a brightness sensor 143, one or more optional sensors 144, a connector 145 for a charging cable, and a visible at least the front side of the housing 160 display device 130. About a connected to the terminal 145 charging cable, which is connected to an electric vehicle can a charging of the battery of the electric vehicle can be performed.

The charging unit 120 may be arranged, for example, in a receptacle of the charging station 100 designed in accordance with the rear side of the charging unit 120. The charging unit 120 may further include, for example, a communication link (e.g., wireless or wired) to the charging station 100. For example, information, e.g. be detected by the charging station 100, are transmitted to the loading unit for further processing.

By means of the user interface 141, for example, inputs of an owner or user of an electric vehicle can be detected. For example, the owner or user can start and / or stop a charging process of an electric vehicle connected to the charging station 100 via a corresponding input to the user interface 141. For example, the user interface 141 may be referred to as be formed touch-sensitive display or via capacitive touch points.

The proximity sensor 142 detects objects in the region of the outside of the housing. In particular, the proximity sensor 142 may include a movement of

Capture objects in the outside of the housing 160.

The brightness sensor 143 detects a brightness in the region of the outside of the housing. In particular, the brightness sensor 143 may detect parameters of the light in the region of the outside of the housing. Parameters of the light may be, for example, (i) light temperature; (ii) brightness; fjii) color; (iv) intensity; (y) frequency; (vi) or a combination thereof, to give a few non-limiting examples. Optionally, one or more other sensors 144, such as. B. a biometric sensor and / or a stimulus sensor for detecting a temperature, a volume, and / or a humidity in the vicinity of the charging unit, to be included. The display device 130 is presently arranged on the base body 150. The housing 160 is at least partially transparent in the area covering the display device 130.

For example, the display device 130 may include at least one optical fiber. The optical waveguide can be arranged on the base body 150 such that the optical waveguide extends along the circumferential edge of the charging unit 120. In the present case, the display device 130 is formed substantially oval-shaped. Furthermore, in the present case, the display device 130 may comprise at least one light source, which transmits a light into one end of the at least one optical waveguide emitted. If light is introduced into the optical waveguide, can over in the

Fiber optic arranged outcoupling elements, the introduced light to the outside, so that the display device 130 lights up. In Fig. 1 it is shown that the display device 130 lights up in one color over the entire oval surface. For example, the display device 130 may light up brightly to illuminate the surroundings of the charging column 100.

For example, the proximity sensor 142 may detect that a metallic (e.g., an electric vehicle) or non-metallic object (e.g., an owner or user of an electric vehicle) is approaching. A control circuit disposed on the base body 150 detects corresponding one or more signals which the proximity sensor 142 has detected by the approach of the object. Based on these one or more signals, the control circuit may have a

 Display device, for example, lights up brightly and accordingly illuminates the environment of the charging station 100.

The brightness sensor 143 may detect, for example, that whether z. B. a (very) bright environment in the region of the outside of the charging unit 120 prevails. Of the

 Brightness sensor 143 can detect, for example, which light temperature prevails in the region of the outside of charging unit 120. Based on these one or more signals, the control circuitry (eg, control circuitry 410 of FIGURE 4, or control circuitry 510 of FIGURE 5) may provide control information for the
