Description

Ladestation zum Laden eines elektrischen Verbrauchers und Verfahren Beschreibung:  Charging station for charging an electrical consumer and method Description:
Die vorliegende Erfindung betrifft eine Ladestation zum Laden eines elektrischen Verbrauchers, insbesondere eine Ladestation zum Laden von Elektrofahrzeugen unter Verwendung von Beleuchtungsmasten. The present invention relates to a charging station for charging an electrical load, in particular a charging station for charging electric vehicles using lighting masts.
In den vergangenen Jahren ist die Zahl von elektrisch betriebenen Fahrzeugen, wie Elektroautos und Elektrofahrräder, Dank innovativer Energiespeicher und effizienterer Elektromotoren stetig gestiegen. Trotzdem besteht aufgrund der geringen Reichweite von Elektrofahrzeugen ein großer Bedarf an Ladestationen. Weiterhin steigt mit der steigenden Anzahl an solchen Fahrzeugen auch grundsätzlich der Bedarf an Ladestationen zum Laden der Fahrzeuge im Straßenverkehr. In recent years, the number of electrically powered vehicles, such as electric cars and electric bicycles, has risen steadily thanks to innovative energy storage and more efficient electric motors. Nevertheless, due to the short range of electric vehicles there is a great need for charging stations. Furthermore, with the increasing number of such vehicles also basically the need for charging stations for charging the vehicles in traffic.
Im Stand der Technik sind zahlreiche Ladestationen beschrieben. Einige Ladestationen werden extra an speziell eingerichteten Parkplätzen im Straßenverkehr aufgebaut, im Untergrund fest verankert und mit teilweise extra installierten Stromanschlüssen an das Stromnetz angebunden. Dieser Aufbau führt zu hohen Kosten. Numerous charging stations are described in the prior art. Some charging stations are specially constructed at specially equipped parking spaces in traffic, firmly anchored in the ground and connected to the power grid with partly extra installed power connections. This construction leads to high costs.
Eine etwas kostengünstigere Alternative dazu ist beispielsweise in der DE 20 201 1 100 062 U1 beschrieben. Hier wird eine Straßenleuchte beschrieben, an welche eine oder mehrere Elektroladestationen für Elektrofahrzeuge angeschlossen werden können. Dadurch wird die vorhandene Stromversorgung in den Straßenleuchten ausgenutzt und muss nicht extra für die Ladestation bereitgestellt werden. Weiterhin ist der Einbau eines Ladekabels mit Zugvorrichtung in den Mast der Straßenleuchte vorgesehen. In diesem Fall, kann ein Ladekabel dann aus der Straßenleuchte herausgezogen werden. A somewhat less expensive alternative to this is described, for example, in DE 20 201 1 100 062 U1. Here a street lamp is described, to which one or more electric charging stations for electric vehicles can be connected. As a result, the existing power supply in the street lights is used and does not need to be provided separately for the charging station. Furthermore, the installation of a charging cable with pulling device is provided in the mast of the street lamp. In this case, a charging cable can then be pulled out of the street light.
Die DE 20 2010 005 543 U1 beschreibt weiterhin eine Stromtankstelle für Kraftfahrzeuge mit einem Anschluss zum Anschließen eines Stromkabels an ein Kraftfahrzeug, wobei die Tankstelle durch eine Straßenleuchte mit Strom versorgt wird. Der Anschluss kann in einem separaten Gehäuse vorgesehen sein, welches an der Straßenleuchte befestigt ist und durch einen neu zu schaffenden Zugang angeschlossen wird, oder in den Mast der Straßenleuchte eingebaut wird. Im letzteren Fall wird der Zugang zum Anschluss dann für den Ladebetrieb durch eine zu öffnende Tür oder Klappe gesteuert. Die vorliegenden Lösungen sind jedoch bei separater Installation von Ladestationen oder der Verwendung von speziellen, zusätzlichen Gehäusen sehr kostenintensiv und benötigen spezielle Umgebungsbedingungen. Dies gilt auch für die aufwändige Nachrüstung bzw. den Umbau von Straßenleuchten. Hierbei ist insbesondere nachteilig, dass die im Inneren eingebauten Komponenten durch die im Betrieb geöffnete Tür schlecht gegen Witterungseinflüsse und Vandalismus und damit verbundenen Beschädigungen sowie Manipulationsversuchen geschützt sind. DE 20 2010 005 543 U1 further describes a charging station for motor vehicles with a connection for connecting a power cable to a motor vehicle, wherein the gas station is powered by a street lamp with power. The connection can be provided in a separate housing, which is attached to the street lamp and is connected by a new access to be created, or is installed in the mast of the street lamp. In the latter case, access to the port is then controlled for loading by a door or flap to be opened. However, the existing solutions are very costly with separate installation of charging stations or the use of special, additional housings and require special environmental conditions. This also applies to the time-consuming retrofitting or conversion of street lights. This is particularly disadvantageous that the built-in components are protected by the open door in operation bad weather and vandalism and associated damage and manipulation attempts.
Somit besteht die Aufgabe der vorliegenden Erfindung darin, eine Ladestation bereitzustellen, welche die Nachteile des Standes der Technik vermeidet und insbesondere einfach und kostengünstig installiert werden kann. Daneben soll die Ladestation einen sicheren Betrieb gewährleisten. Thus, the object of the present invention is to provide a charging station, which avoids the disadvantages of the prior art and in particular can be installed easily and inexpensively. In addition, the charging station should ensure safe operation.
Die Aufgabe wird durch die Gegenstände der Erfindung gemäß den unabhängigen Ansprüchen 1 und 8 gelöst. Vorteilhafte Ausführungsformen sind in den abhängigen Ansprüchen angegeben. The object is solved by the objects of the invention according to independent claims 1 and 8. Advantageous embodiments are given in the dependent claims.
Soweit nachstehend in der Beschreibung und in den Patentansprüchen der Begriff "Um- fangsabmessungen" bezogen auf das Gehäuse verwendet wird, ist darunter insbesondere zu verstehen, dass das Gehäuse einen Umfang beziehungsweise räumliche Maße aufweist, die derart ausgebildet sind, dass das Gehäuse die Zugangsöffnung verschließen kann. As far as hereinafter in the description and in the claims the term "circumferential dimensions" is used with respect to the housing, it is to be understood in particular that the housing has a circumference or spatial dimensions, which are designed such that the housing close the access opening can.
Soweit nachstehend in der Beschreibung und in den Patentansprüchen der Begriff "Zugangsöffnung zu einem Innenraum einer Einrichtung mit Stromversorgung" verwendet wird, ist darunter insbesondere eine Öffnung zu verstehen, welche einen Zugang zur Stromversorgung der Einrichtung ermöglicht. As used below in the description and in the claims, the term "access opening to an interior of a device with power supply", including in particular an opening to understand, which allows access to the power supply of the device.
Soweit nachstehend in der Beschreibung und in den Patentansprüchen der Begriff "Laden" verwendet wird, ist darunter das Aufladen von Energiespeichern, aber auch ein Laden im Sinne von mit Strom versorgen zum Betrieb des Verbrauchers zu verstehen. Insofar as the term "store" is used below in the description and in the claims, this includes the charging of energy stores, but also charging in the sense of being supplied with power for the operation of the consumer.
Die erfindungsgemäße Ladestation dient zum Laden eines elektrischen Verbrauchers, wobei die Ladestation ein Gehäuse umfasst, welches zum Verschließen einer bereits vorhandenen Zugangsöffnung zu einem Innenraum einer Einrichtung mit Stromversorgung ausgebildet ist, und die Ladestation an die Stromversorgung der Einrichtung anschließbar ist. Die erfindungsgemäße Ladestation ersetzt somit eine ursprünglich vorhandene Verschlusseinrich- tung, wie eine Masttür, welche normalerweise den Zugang zum Innenraum der Einrichtung verschließt. The charging station according to the invention is used for charging an electrical load, wherein the charging station comprises a housing which is designed for closing an existing access opening to an interior of a device with power supply, and the charging station can be connected to the power supply of the device. The charging station according to the invention thus replaces an originally existing locking device. As a mast door, which normally closes the access to the interior of the device.
Das Gehäuse umfasst dabei Seitenwände, sowie eine Frontwand und eine Rückwand, wobei die Rückwand in Richtung des Innenraums zeigt, wenn die Ladestation in die Einrichtung eingesetzt ist. Die Länge der Seitenwände insgesamt bzw. ihre Umfangsabmessung richtet sich im Wesentlichen nach dem Umfang der Zugangsöffnung der Einrichtung. The housing thereby comprises side walls, as well as a front wall and a rear wall, wherein the rear wall points in the direction of the interior, when the charging station is inserted into the device. The length of the side walls as a whole or their circumferential dimension depends essentially on the circumference of the access opening of the device.
Durch die erfindungsgemäße Lösung ist es nicht mehr nötig, bestehenden strombereitstellenden Infrastrukturen, also eine beliebige Einrichtung mit Stromversorgung, derart zu verändern, dass die Ladestation mittels eines konstruktiv aufwändigen Ein- oder Anbaus realisiert wird. Dazu wird einfach die vorhandene Vorrichtung zum Verschließen der Zugangsöffnung durch die erfindungsgemäße Ladestation ausgetauscht. Dieses hat neben der konstruktiven Einfachheit, welche den vorhandenen Innenraum der Einrichtung teilweise ausnutzt auch den Vorteil, dass die Zugangsöffnung auch nach dem Einbau der Ladestation und auch im Ladebetrieb vollständig verschlossen bleibt und der Innenraum vor Witterungseinflüssen, Vandalismus und Manipulationsversuchen geschützt bleibt. Darüber hinaus kann die Zugangsöffnung für den Fall einer Reparatur/Neulieferung der Ladestation einfach wieder in der Zwischenzeit durch eine herkömmliche Masttür verschlossen werden. The inventive solution, it is no longer necessary to existing power supply infrastructure, so any device with power supply to change such that the charging station is realized by means of a structurally complex installation or extension. For this purpose, the existing device for closing the access opening is simply replaced by the charging station according to the invention. This has in addition to the constructive simplicity, which partially exploits the existing interior of the device also has the advantage that the access opening remains completely closed even after the installation of the charging station and in charging mode and the interior is protected from the weather, vandalism and manipulation attempts. In addition, in the event of a repair / re-delivery of the charging station, the access opening can simply be closed again in the meantime by a conventional mast door.
In einer bevorzugten Ausführungsform der erfindungsgemäßen Ladestation ist die Einrichtung mit Stromversorgung ein Beleuchtungsmast oder eine strombetriebene Anzeigeeinrichtung für Informationen. In diesem Fall wird eine üblicherweise vorhandene Masttür oder eine Anzeigeeinrichtungstür, welche die Zugangsöffnung verschließt, einfach durch die Ladestation ersetzt. In a preferred embodiment of the charging station according to the invention, the device with power supply is a lighting mast or a current-driven display device for information. In this case, a commonly available mast door or display door which closes the access opening is simply replaced by the cradle.
Der Beleuchtungsmast umfasst weiterhin eine oder mehrere Leuchtmittel. Unter Beleuchtungsmast ist dabei insbesondere eine elektrisch betriebene Straßenleuchte jedweder Art zu verstehen, wie sie zur Beleuchtung von öffentlichen und privaten Straßen und Plätzen allgemein üblich vorzufinden ist. Daneben kann der Beleuchtungsmast einen so genannten Kabelübergangskasten oder Netzanschlusskasten als Stromversorgung beziehungsweise Endpunkt der Stromversorgung aufweisen. In einigen Fällen kann der Beleuchtungsmast die Stromversorgung auch durch eine Steckdose realisieren. The lighting mast further comprises one or more bulbs. Under lighting tower is in particular an electrically operated street lamp of any kind to understand, as it is commonly found to illuminate public and private streets and squares. In addition, the lighting mast can have a so-called cable junction box or power connection box as a power supply or end point of the power supply. In some cases, the lighting mast can also provide power through a power outlet.
Im Falle eines Beleuchtungsmastes entsprechen die Länge der Seitenwände des Gehäuses insgesamt bzw. ihre Umfangsabmessung im Wesentlichen dem Umfang der Zugangsöffnung zum Innenraum der Einrichtung. Die Kantenlänge der Seitenwände zwischen Frontwand und Rückwand können dabei eine Länge von 10 - 25 cm, vorzugsweise 12 - 19 cm aufweisen. In the case of a lighting mast, the length of the side walls of the housing as a whole or their circumferential dimension substantially correspond to the circumference of the access opening to the interior of the facility. The edge length of the side walls between the front wall and the rear wall can have a length of 10 to 25 cm, preferably 12 to 19 cm.
Im Falle der Anzeigeeinrichtungen für Informationen umfassen diese im Besonderen Anzeigeelemente mit rotierenden und/oder beleuchteten Werbeinformationen sowie beleuchtete Verkehrsschilder. Dabei umfassen die Anzeigeeinrichtungen beispielsweise eine oder mehrere Masten mit Masttüren, auf denen die Anzeigeelemente angeordnet sind. In the case of information display devices, these include, in particular, display elements with rotating and / or illuminated advertising information and illuminated traffic signs. In this case, the display devices include, for example, one or more masts with mast doors on which the display elements are arranged.
Weiterhin können die erfindungsgemäßen Ladestationen auch in Anzeigeeinrichtungen z.B. an Bushaltestellen bzw. zum Verschließen der dortigen Zugangsöffnungen eingesetzt werden. In diesem Fall werden die auf der Rückseite der zumeist Quader-förmigen Anzeigeeinrichtungen entsprechenden Vorrichtungen zum Verschließen durch die erfindungsgemäßen Ladestationen ersetzt. Furthermore, the charging stations according to the invention can also be used in display devices, e.g. be used at bus stops or to close the local access openings. In this case, the closing devices on the back of the generally cuboid display devices are replaced by the charging stations according to the invention.
Vorzugsweise ist der elektrische Verbraucher ein Elektrofahrzeug, ein Elektrozweirad, ein Elektrofahrrad oder ein sonstiger fahrbarer Verbraucher. Preferably, the electrical load is an electric vehicle, an electric bicycle, an electric bicycle or any other mobile consumer.
Im Falle eines sonstigen fahrbaren Verbrauchers sind hier beispielsweise Verkaufsstände und beweglichen Verkaufsanhänger für Wochenmärkte oder Baucontainer zu verstehen. In the case of another mobile consumer, for example, sales stands and mobile sales trailers for weekly markets or construction containers are to be understood here.
Vorzugsweise wird die Zugangsöffnung durch die erfindungsgemäße Ladestation mithilfe eines oder mehrerer Verschlusselemente, beispielsweise eines Sperrriegel oder einer Hakenschraube, fest verschlossen. Dabei reichen Teile des Verschlusselementes, also zum Beispiel der Haken, in den Innenraum der Einrichtung und durch Drehung, zum Beispiel der Schraube, wird mittels des Hakens die Ladestation im Inneren der Einrichtung fixiert beziehungsweise fest verschlossen. Preferably, the access opening is firmly closed by the charging station according to the invention by means of one or more closure elements, such as a locking bar or a hook screw. Here are parts of the closure element, so for example the hook, in the interior of the device and by rotation, for example, the screw is fixed by means of the hook, the charging station inside the device or firmly closed.
Das Gehäuse der Ladestation weist an seinen Seitenwänden oder an der Rückwand einen umlaufenden überstehenden Rand auf, welcher so ausgebildet ist, dass er die Zugangsöffnung bei eingesetzter Ladestation vollständig verschließt. Der umlaufende Rand ist vorzugsweise 1 bis 4 cm breit und passt sich an die geometrische Form der Einrichtung an, wodurch ein dichtes Verschließen der Zugangsöffnung erreicht wird. Zusätzlich kann eine Gummierung auf dem Rand zwischen Einrichtung, d.h. eines Randes der Zugangsöffnung, und Rand vorgesehen sein, wodurch das Verschließen der Zugangsöffnung weiter verbessert wird. Vorzugsweise ist das Verschlusselement im Rand des Gehäuses angeordnet. The housing of the charging station has on its side walls or on the rear wall on a circumferential protruding edge, which is designed so that it completely closes the access opening with inserted charging station. The peripheral edge is preferably 1 to 4 cm wide and adapts to the geometric shape of the device, whereby a tight closing of the access opening is achieved. In addition, a gumming on the edge between device, i. an edge of the access opening, and edge, whereby the closing of the access opening is further improved. Preferably, the closure element is arranged in the edge of the housing.
In einer bevorzugten Ausführungsform des Randes weist dieser mindestens teilweise ein kraftaufnehmendes Profil auf. Das hat den Vorteil, dass bei einer versehentlichen oder ab- sichtlichen Krafteinwirkung auf die Ladestation, beispielsweise ein Stoß oder Fußtritt gegen die Ladestation, die unmittelbare Krafteinwirkung auf die Ladestation und damit zum Beispiel Erschütterungen vermindert werden. Ein kraftaufnehmendes Profil kann beispielsweise durch ein wellenartiges oder U-förmiges Profil realisiert werden. Das„U" des U-förmigen Profils kann dabei derart in den Rand eingelassen sein, dass die offene Seite des„U" zum Rand der Zugangsöffnung der Einrichtung ausgerichtet ist. Bei einem Stoß können die Schenkel des„U" diesen durch reversibles, kurzzeitiges Verbiegen aufnehmen. In ähnlicher Weise kann ein Stoß bei einem wellenartigen Profil aufgenommen werden, indem sich das wellenartige Profil reversibel, kurzzeitig verformt. In a preferred embodiment of the edge, this at least partially has a force-absorbing profile. This has the advantage that in case of accidental or Visible force on the charging station, such as a shock or kick against the charging station, the direct force on the charging station and thus, for example, vibrations are reduced. A force-absorbing profile can be realized for example by a wave-like or U-shaped profile. The "U" of the U-shaped profile can be embedded in the edge in such a way that the open side of the "U" is aligned to the edge of the access opening of the device. In the event of an impact, the legs of the "U" can absorb them by reversible, short-term bending, Similarly, a shock in a wave-like profile can be accommodated by the wave-like profile reversibly deforming for a short time.
In einer erfindungsgemäßen Ausführungsform des Gehäuses der Ladestation ist der umlaufende überstehenden Rand derart an den Seitenwänden oder an der Rückwand angeordnet, dass ein Teil des Gehäuses bzw. der Seitenwände so in die Zugangsöffnung einsetzbar ist, dass dieser Teil in den Innenraum der Einrichtung hineinragt. Der andere Teil des Gehäuses befindet sich dann au ßerhalb der Einrichtung. Die Seitenwände des Gehäuses können dabei eine Kantenlänge zwischen Frontwand und Rückwand von 10 - 25 cm, vorzugsweise 12 - 19 cm aufweisen. Vorzugsweise ist der umlaufende Rand derart auf den Seitenwänden angeordnet, dass die Ladestation mit ihrem Gehäuse bzw. einem Teil der Seitenwände 2 bis 8 cm, besonders bevorzugt 2 bis 4 cm in die Einrichtung hineinragt, während der verbleibende Teil der Seitenwände des Gehäuses 8 bis 15 cm, vorzugsweise etwa 10 cm außerhalb des Innenraums übersteht. Dadurch wird zum einen ein Teil des Innenraumes der Einrichtung ausgenutzt, um den Überstand zum Beispiel aus Sperrigkeitsgründen oder ästhetischen Gründen zu reduzieren. Zum anderen wird die Einheit aus Ladestation und Einrichtung mit Ladestation konstruktiv stabiler und ist so auch besser gegen Vandalismus oder versehentliche Krafteinwirkung gesichert. In an embodiment according to the invention of the housing of the charging station, the circumferential protruding edge is arranged on the side walls or on the rear wall such that a part of the housing or the side walls can be inserted into the access opening such that this part protrudes into the interior of the device. The other part of the housing is then outside the device. The side walls of the housing can have an edge length between front wall and rear wall of 10 - 25 cm, preferably 12 - 19 cm. Preferably, the peripheral edge is arranged on the side walls such that the charging station protrudes with its housing or part of the side walls 2 to 8 cm, more preferably 2 to 4 cm into the device, while the remaining part of the side walls of the housing 8 to 15 cm, preferably about 10 cm outside the interior. As a result, on the one hand a part of the interior of the device is used to reduce the supernatant, for example, for reasons of barrier or aesthetic reasons. On the other hand, the unit of charging station and device with charging station is structurally more stable and is thus better protected against vandalism or accidental force.
In einer bevorzugten Ausführungsform der Ladestation sind in dem Gehäuse mindestens folgende Komponenten einzeln oder in Kombination angeordnet: ein Stromzähler mit einem Kabel, mit welchem der Stromzähler an die Stromversorgung anschließbar ist, eine Steuerelektronik, eine Sicherung, einen Fehlerstrom-Schutzschalter, einen Schütz und ein Steckverbindungselement, mit welchem der elektrische Verbraucher an die Ladestation anschließbar ist. Die Komponenten können teilweise auf einer Grundplatte angeordnet sein, welche im Gehäuse, beispielsweise an der Rückwand, befestigt ist. Das Kabel, welches die Ladestation und die Stromversorgung verbindet, kann wahlweise durch eine Öffnung in der Rückwand oder durch eine Öffnung in dem Teil der Seitenwand geführt werden, welcher beim Einsetzen der Ladestation im Innenraum angeordnet ist. Der Begriff Steckverbindungselement meint dabei wahlweise einen Stecker oder eine Steckdose, bevorzugt ist eine Steckdose. In a preferred embodiment of the charging station at least the following components are arranged individually or in combination in the housing: an electricity meter with a cable, with which the electricity meter is connected to the power supply, an electronic control unit, a fuse, a residual current circuit breaker, a contactor and a Plug connection element with which the electrical load can be connected to the charging station. The components may be partially disposed on a base plate which is fixed in the housing, for example on the rear wall. The cable which connects the charging station and the power supply can optionally be led through an opening in the rear wall or through an opening in the part of the side wall which is arranged in the interior when the charging station is inserted. The term plug-in element means either a plug or a socket, preferably is a socket.
Bezüglich des Steckverbindungselementes wird besonders bevorzugt ein standardisierter Steckertyp oder entsprechende standardisierte Steckdose verwendet. Dabei umfasst das Steckverbindungselement im Allgemeinen folgende Komponenten: einen Leiter L1 , verwendet im einphasigen und dreiphasigen Betrieb mit 230V, einen Leiter L2, verwendet im dreiphasigen Betrieb mit insgesamt 400V Drehstrom, einen Leiter L3, verwendet im dreiphasigen Betrieb mit insgesamt 400V Drehstrom, einen Neutralleiter, der neutrale Gegenpol für die drei Leiter, einen Control Pilot Kontakt, dient der Kommunikation zwischen Ladestation und Fahrzeug, einen Erdkontakt, zum sicheren Kontakt zur Erdung der Verbindung und des Fahrzeugs während des Ladevorgangs, und einen Proximity Kontakt, dient der Ladestation zur Detektion eines eingesteckten Kabels und zur Erkennung der Stromfestigkeit des Kabels über eine Widerstandskodierung. Dies ermöglicht, dass die Ladestation bei Einsatz eines Kabels ohne eine spezielle Ladeintelligenz mit allen Fahrzeugtypen kompatibel ist. In diesem Fall wird die Ladeintelligenz in der Steuerelektronik der Ladestation realisiert. Die Kommunikation erfolgt dabei vorzugsweise über Pulsweitenmodulation (PWM) und geschaltete Widerstände oder über Power Line Communication (PLC), jeweils entsprechend der gültigen Standards. With regard to the plug connection element, a standardized plug type or corresponding standardized socket is particularly preferably used. The connector element generally comprises the following components: a conductor L1, used in single-phase and three-phase operation with 230V, a conductor L2, used in three-phase operation with a total of 400V three-phase, a conductor L3, used in three-phase operation with a total of 400V three-phase, a neutral conductor , the neutral opposite pole for the three conductors, a control pilot contact, is used for communication between charging station and vehicle, a ground contact, for safe contact to ground the connection and the vehicle during charging, and a proximity contact, the charging station is used to detect a inserted cable and to detect the current strength of the cable via a resistance coding. This allows the charging station to be compatible with all types of vehicles when using a cable without special charging intelligence. In this case, the Ladeintelligenz is realized in the control electronics of the charging station. The communication preferably takes place via pulse width modulation (PWM) and switched resistors or via power line communication (PLC), in each case according to the valid standards.
Die Steuerelektronik umfasst mindestens folgende Einheiten einzeln oder in Kombination: eine Mobilfunkeinheit, eine Nutzer-Identifikations-RFID-Einheit und/oder eine Einheit zur Identifikation der Verbindung gegenüber der Ladestation, wobei der Begriff Verbindung die Art des Ladekabels und/oder den zu ladenden Verbraucher meint. The control electronics comprise at least the following units individually or in combination: a mobile radio unit, a user identification RFID unit and / or a unit for identifying the connection with respect to the charging station, wherein the term connection means the type of charging cable and / or the load to be charged means.
In einer weiteren Ausführungsform der Ladestation umfasst diese eine Bedienungseinrichtung, welche auf dem Gehäuse der Ladestation angeordnet und zur Kommunikation zwischen einem Benutzer, der Ladestation und/oder dem elektrischen Verbraucher eingerichtet ist. Beispielsweise besteht die Bedienungseinrichtung aus einem Display und einer Tastatur oder wahlweise aus einem Touchscreen, wodurch die Kommunikation zur Abwickeln des Ladens bzw. des Ladevorgangs vereinfacht und/oder gesteuert wird. In a further embodiment of the charging station, this comprises an operating device which is arranged on the housing of the charging station and is set up for communication between a user, the charging station and / or the electrical consumer. For example, the operating device consists of a display and a keyboard or optionally of a touch screen, whereby the communication for handling the loading or the charging process is simplified and / or controlled.
In einer besonders bevorzugten Ausführungsform der Ladestation sind der Stromzähler mit Kabel, die Steuerelektronik, die Sicherung, der Fehlerstrom-Schutzschalter und der Schütz innerhalb des Gehäuses der Ladestation und von außen nicht sichtbar angeordnet, wobei das Zählwerk des Stromzählers durch eine durchsichtige Öffnung im Gehäuse von au ßen sichtbar sein kann. Das Steckverbindungselement ist dagegen außerhalb des Gehäuses angeordnet und mit dem elektrischen Verbraucher verbindbar. In einer besonderen Ausführungsform kann die Ladestation zusätzlich einen Wandler von Wechselspannungsladestrom auf Gleichspannungsladestrom umfassen, welcher ebenfalls im Gehäuse der Ladestation angeordnet ist. Diese Ausführungsform wird insbesondere dann realisiert, wenn der gewandelte Ladestrom nur gering sein muss, beispielsweise zum Laden von Fahrrädern. In a particularly preferred embodiment of the charging station of the electricity meter with cable, the control electronics, the fuse, the residual current circuit breaker and the contactor within the housing of the charging station and are not visible from the outside, the counter of the electricity meter through a transparent opening in the housing of outside can be visible. By contrast, the plug-in connection element is arranged outside the housing and can be connected to the electrical load. In a particular embodiment, the charging station may additionally comprise a converter of AC charging current to DC charging current, which is also arranged in the housing of the charging station. This embodiment is realized in particular when the converted charging current only has to be low, for example for loading bicycles.
Zusätzlich kann die Ladestation einen Unterbrechungsschalter umfassen, welcher einen Ladevorgang unterbricht, wenn die Ladestation während des Ladens aus der Zugangsöffnung teilweise oder vollständig entfernt wird, also die Zugangsöffnung nicht mehr verschließt. In addition, the charging station may include an interruption switch which interrupts a charging operation when the charging station is partially or completely removed from the access opening during charging, that is, when the access opening no longer closes.
Weiterhin wird die Aufgabe durch ein Verfahren zum Laden eines elektrischen Verbrauchers unter Verwendung der erfindungsgemäßen Ladestation gelöst, wobei die Ladestation über das Kabel am Stromzähler mit der Stromversorgung der Einrichtung verbunden wird und der elektrische Verbraucher über das Steckverbindungselement mit der Ladestation verbunden wird. Die Ladestation wurde dabei im Austausch mit einer vorhandenen Verschlussvorrichtung zum Verschließen der Zugangsöffnung der Einrichtung, z.B. einer Masttür, zuvor in die Zugangsöffnung eingesetzt. Furthermore, the object is achieved by a method for charging an electrical load using the charging station according to the invention, wherein the charging station is connected via the cable to the electricity meter with the power supply of the device and the electrical load is connected via the connector element with the charging station. The loading station was replaced with an existing closure device for closing the access opening of the device, e.g. a mast door, previously inserted into the access opening.
Dazu ist im Innenraum der Einrichtung ein so genannter Kabelübergangskasten oder Netzanschlusskasten angeordnet, welche die Stromversorgung der Einrichtung beziehungsweise den Endpunkt des Stromversorgungsanschlusses darstellt und normalerweise zu einem Stromnetzbetreiber gehört. An diesem Kabelübergangskasten wird das Kabel des Stromzählers der Ladestation beispielsweise durch einen Mitarbeiter des Strom netzbetreibers angeschlossen und so die Ladestation mit Strom versorgt. Nach dem Anschluss der Ladestation wird diese in die Zugangsöffnung eingesetzt und verschließt somit die Zugangsöffnung zum Innenraum. Anschließend kann in die außen sichtbare und zugängliche Steckverbindung der Ladestation, vorzugsweise eine Steckdose, der elektrische Verbraucher mittels eines passenden Steckers angeschlossen bzw. mit der Steckdose verbunden werden. For this purpose, a so-called cable junction box or power connection box is arranged in the interior of the device, which represents the power supply of the device or the end point of the power supply connection and normally belongs to a power grid operator. At this cable junction box, the cable of the electricity meter of the charging station, for example, connected by an employee of the power grid operator and so the charging station with power. After connecting the charging station, this is inserted into the access opening and thus closes the access opening to the interior. Subsequently, in the externally visible and accessible plug connection of the charging station, preferably a socket, the electrical consumer can be connected by means of a suitable plug or connected to the socket.
In einer besonderen Ausführungsform kann die Stromversorgung in der Einrichtung anstelle eines Kabelübergangskastens auch durch eine einfache Steckdose realisiert sein. Dieses kann beispielsweise dann der Fall sein, wenn der Kabelübergangskasten au ßerhalb der Einrichtung installiert ist und die Einrichtung der Stromversorgung über ein Kabel an den Kabelübergangskasten angeschlossen wurde. In diesem Fall umfasst das Kabel des Stromzählers zusätzlich einen Stecker, welcher in die Steckdose eingesteckt werden kann. Ausführungsbeispiele werden nun unter Bezugnahme auf die beigefügten Figuren beschrieben. Die einzelnen Figuren zeigen: In a particular embodiment, the power supply in the device instead of a cable junction box can also be realized by a simple socket. This may for example be the case when the cable junction box is installed outside the device and the device of the power supply has been connected via a cable to the cable junction box. In this case, the cable of the electricity meter also includes a plug, which can be plugged into the socket. Embodiments will now be described with reference to the accompanying drawings.
