Description
Die Erfindung betrifft eine Ladedose, einen Ladestecker, einen Laderoboter sowie ein Verfahren zum pilotierten Laden eines Elektro- oder Plugin-Hybridfahrzeugs.The invention relates to a charging socket, a charging plug, a charging robot and a method for piloted charging of an electric or plug-in hybrid vehicle.
Aufgrund der Dicke und Starrheit von Ladekabeln von Elektrofahrzeugen ist es bekannt, das Stecken eines Ladesteckers in eine Ladedose des Elektro- oder Plugin-Hybridfahrzeuges automatisiert durch einen Laderoboter vorzunehmen. Dabei kann dem Laderoboter fest ein Ladekabel mit Ladestecker zugeordnet sein oder aber der Laderoboter fährt automatisiert einzelne Ladestationen an. Dabei ist es bekannt, dass im oder am Ladestecker eine Kamera verbaut ist, mittels derer die Kontur der Ladedose erfasst wird, um den Ladestecker zur Ladedose auszurichten.Due to the thickness and rigidity of charging cables of electric vehicles, it is known to plug a charging plug into a charging socket of the electric or plug-in hybrid vehicle in an automated manner using a charging robot. A charging cable with a charging plug can be permanently assigned to the charging robot, or the charging robot automatically drives to individual charging stations. It is known that a camera is installed in or on the charging plug, by means of which the contour of the charging socket is recorded in order to align the charging plug with the charging socket.
Aus der
Der Erfindung liegt das technische Problem zugrunde, eine Ladedose für ein Elektro- oder Plugin-Hybridfahrzeug zu schaffen, mittels derer ein pilotiertes Laden eines Elektro- oder Plugin-Hybridfahrzeugs auch bei schlechten Lichtverhältnissen ermöglicht wird. Ein weiteres technisches Problem liegt in der Schaffung eines verbesserten Ladesteckers sowie eines verbesserten Laderoboters. Ein weiteres technisches Problem ist das Zurverfügungstellen eines Verfahrens zum pilotierten Laden.The invention is based on the technical problem of creating a charging socket for an electric or plug-in hybrid vehicle by means of which piloted charging of an electric or plug-in hybrid vehicle is made possible even in poor lighting conditions. Another technical problem lies in the creation of an improved charging plug and an improved charging robot. Another technical problem is the provision of a method for piloted charging.
Die Lösung des technischen Problems ergibt sich durch eine Ladedose mit den Merkmalen des Anspruchs 1, einen Ladestecker mit den Merkmalen des Anspruchs 5, einen Laderoboter mit den Merkmalen des Anspruchs 7 sowie ein Verfahren zum pilotierten Laden eines Elektro- oder Plugin-Hybridfahrzeugs mit den Merkmalen des Anspruchs 8. Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.The solution to the technical problem results from a charging socket with the features of
Hierzu weist die Ladedose für ein Elektro- oder Plugin-Hybridfahrzeug mindestens eine Reflexionsschicht auf. Hiermit wird die Erfassung der Ladedose auch bei schwierigen Beleuchtungsverhältnissen erheblich verbessert. Der Vorteil gegenüber aktiv leuchtenden Elementen wie beispielsweise LEDs ist das einfache Nachrüsten sowie dass keine Energieversorgung notwendig ist. Die Reflexionsschicht kann dabei derart strukturiert sein, dass diese eine eindeutige räumliche Orientierung gewährleistet. Hierzu weist diese beispielsweise eine Struktur mit drei eindeutigen Punkten auf. Die Gefahr der Verschmutzung der Reflexionsschicht ist gering, da im Fahrbetrieb oder beim abgestellten Fahrzeug, die Ladedose mit einer normativ geforderten Abdeckung oder beim Laden durch den Ladestecker vor Verschmutzung geschützt ist.For this purpose, the charging socket for an electric or plug-in hybrid vehicle has at least one reflective layer. This significantly improves the detection of the charging socket even in difficult lighting conditions. The advantage over actively illuminated elements such as LEDs is that they are easy to retrofit and that no power supply is required. The reflective layer can be structured in such a way that it ensures a clear spatial orientation. For this purpose, it has, for example, a structure with three clear points. The risk of soiling the reflective layer is low, since when driving or when the vehicle is parked, the charging socket is protected from soiling with a cover required by the standards or when charging by the charging plug.
In einer Ausführungsform ist die Reflexionsschicht als Reflexfolie ausgebildet, die auch als retroreflektierende Folie bezeichnet wird. Eine Reflexfolie wirft eintreffendes Licht unabhängig vom Einfallswinkel in Richtung der Lichtquelle zurück. Reflexfolien besitzen einen spiegelnden Untergrund, in dem kleine Glaskugeln eingelassen sind. Der eintreffende Lichtstrahl wird beim Eintritt in die Glaskugel gebrochen, vom Untergrund reflektiert und beim Austritt wieder gebrochen. In der Summe entsteht dadurch eine Reflexion in die ursprüngliche Richtung, wodurch ein Großteil des Lichts wieder auf die Lichtquelle trifft. Hierdurch wird die Erfassung gegenüber einfachen Reflexionsschichten erheblich verbessert.In one embodiment, the reflective layer is designed as a reflective film, which is also referred to as a retroreflective film. A reflective film throws incoming light back in the direction of the light source regardless of the angle of incidence. Reflective foils have a reflective background in which small glass spheres are embedded. The incoming light beam is refracted when it enters the glass ball, reflected from the ground and refracted again when it exits. In total, this creates a reflection in the original direction, which means that a large part of the light hits the light source again. This considerably improves the detection compared to simple reflective layers.
In einer weiteren Ausführungsform weist die Ladedose mindestens drei Reflexionsschichten auf, was eine eindeutige Lageerfassung ermöglicht (analog der drei ausgewählten Punkte einer Schicht).In a further embodiment, the charging socket has at least three reflective layers, which enables a clear position detection (analogous to the three selected points of a layer).
In einer weiteren Ausführungsform weist die Ladedose Dome als Berührschutz auf, wobei die mindestens eine Reflexionsschicht auf der Oberseite mindestens eines Domes angeordnet ist, was die Erkennbarkeit aufgrund der exponierten Lage verbessert.In a further embodiment, the charging socket has domes as contact protection, the at least one reflective layer being arranged on the top of at least one dome, which improves the visibility due to the exposed position.
Der Ladestecker für ein Elektro- oder Plugin-Hybridfahrzeug ist dadurch gekennzeichnet, dass im oder am Ladestecker mindestens eine Kamera angeordnet ist, wobei im oder am Ladestecker mindestens eine Lichtquelle angeordnet ist, sodass die Reflexionsschicht aktiv mit Licht bestrahlt werden kann, was die Erfassung der Reflexionsschicht und damit der Ladedose verbessert.The charging connector for an electric or plug-in hybrid vehicle is characterized in that at least one camera is arranged in or on the charging connector, with at least one light source being arranged in or on the charging connector so that the reflective layer can be actively irradiated with light, which enables the detection of the Reflective layer and thus the charging socket improved.
In einer Ausführungsform ist die mindestens eine Lichtquelle als LED ausgebildet.In one embodiment, the at least one light source is designed as an LED.
Der Laderoboter ist derart ausgebildet, anhand der Daten einer Kamera mindestens eine Reflexionsschicht auf einer Ladedose zu erfassen und anhand der Daten einen Ladestecker zur Ladedose auszurichten. Hinsichtlich weiterer Ausgestaltungen wird auf die vorangegangenen Ausführungen Bezug genommen.The charging robot is designed to use the data from a camera to detect at least one reflective layer on a charging socket and to align a charging plug with the charging socket using the data. With regard to further refinements, reference is made to the preceding statements.
Das Verfahren zum pilotierten Laden eines Elektro- oder Plugin-Hybridfahrzeuges erfolgt dadurch, dass ein Laderoboter automatisiert einen Ladestecker in eine Ladedose eines Elektro- oder Plugin-Hybridfahrzeugs steckt, wobei mittels mindestens einer Kamera im oder am Ladestecker eine Position mindestens einer Reflexionsschicht an der Ladedose erfasst wird, wobei der Laderoboter in Abhängigkeit der erfassten Reflexionsschicht den Ladestecker zur Ladedose ausrichtet und einsteckt. Dabei kann die Kamera auch am Laderoboter angeordnet sein, sodass beim Greifen des Ladesteckers durch den Laderoboter die Kamera am Ladestecker ist.The method for piloted charging of an electric or plug-in hybrid vehicle is carried out in that a charging robot automatically plugs a charging plug into a charging socket of an electric or Plug-in hybrid vehicle, with a position of at least one reflective layer on the charging socket being detected by means of at least one camera in or on the charging plug, the charging robot aligning the charging plug to the charging socket and inserting it as a function of the detected reflective layer. The camera can also be arranged on the charging robot, so that when the charging robot grips the charging plug, the camera is on the charging plug.
In einer Ausführungsform wird in Abhängigkeit der Beleuchtungsverhältnisse automatisch mindestens eine Lichtquelle im oder am Ladestecker eingeschaltet.In one embodiment, at least one light source in or on the charging plug is automatically switched on as a function of the lighting conditions.
