Abstract

The invention relates to a charging device for an electric vehicle having the features of the preamble of the main claim, and to an adapter having the features of the first claim. A further coordinate claim relates to an electric vehicle comprising the charging device. The invention provides a charging device for an electric vehicle having a charging cable comprising an electrical plug connector, the electrical plug connector comprising electrical alternating-current contacts for charging with alternating current and also comprising electrical direct-current contacts for charging with direct current. The charging device also has at least one adapter for connecting the electrical alternating-current contacts to a plug socket for alternating current. The adapter can therefore be connected both to the alternating-current contacts of the charging device and to alternating-current contacts of a domestic plug socket. Owing to the adapter, it is possible to charge a motor vehicle throughout the world from any desired domestic plug socket, specifically independently of the design of the alternating-current contacts of the charging device.

Es stehen da mit zwei verschiedene Anschlussmög lic hkeiten für ein Aufladen des Energiespeichers eines zugehörigen Elektrofahrzeugs zur Verf ügung . Electric vehicles should be able to be charged both on standard household sockets with alternating current as well as charging stations that provide direct current with high performance. Charging with DC at a charging station allows charging of the energy storage of an electric vehicle in a short time, for example within 30 minutes or shorter.

Vor diesem Hintergrund ist es Aufgabe der Erfindung, eine Vorrichtung und ein Verfahren für ein einfaches Aufladen eines Elektrofahrzeugs bereitzustellen. Against this background, it is an object of the invention to provide an apparatus and a method for a simple charging of an electric vehicle.
Zur Lösu ng der Aufgabe wird insbesondere eine Ladeeinrichtung mit den Merkm alen des Anspruchs 1 vorgeschlag en. Vorteilhafte Ausgestaltungen sind Gegensta nd der U nteransprüche. To solving the problem, in particular a charging device with the Merkm alen of claim 1 is proposed. Advantageous embodiments are Gegensta the U nteransprüche.
Zur Lösung der Aufgabe wird eine Ladeeinrichtung für ein Elektrofahrzeug mit einem Ladekabel umfassend einen elektrischen Steckverbinder bereitgestellt, wobei der elektrische Steckverbinder elektrische Wechselstromkontakte für ein Aufladen mit Wechselstrom sowie el ektrische Gleichstromkontakte für ein Aufladen mit Gleichstrom u mfasst. Die Ladeeinrichtung weist ferner wenigstens einen Ada pter für ein Verbinden der elektrischen Wechselstromkontakte mit einer Steckdose für Wechselstrom a uf. Der Adapter kann also sowohl mit den Wechselstromkontakten der Ladeeinrichtung als auch mit Wechselstromkontakten einer haushaltsüblichen Steckdose verbunden werde n. Durch den Adapter wird es möglich, ein Kraftfahrzeug an einer belie bigen haushaltsüblichen Steckdose weltweit aufzuladen und zwa r una b hä ngig von der Beschaffenheit der Wechselstromkontakte der Ladeeinrichtung. To achieve the object, a charging device for an electric vehicle with a charging cable comprising an electrical connector is provided, wherein the electrical connector AC electrical AC contacts for charging with AC and el ektrische Gleichstromkontakte for charging with DC u. The charging device further comprises at least one adapter for connecting the AC electrical contacts to an AC outlet. The adapter can thus be connected both with the AC contacts of the charger and with AC contacts a household standard socket n. Through the adapter, it is possible to charge a motor vehicle at a belie sary household common outlet worldwide and zwa r irrespective of the nature of the AC contacts of the charging device.
Der Adapter umfasst in einer Ausführu ngsform ein Elektroka bel, dessen Enden mit elektrischen Steckverbindern versehen sind . Wird a n einer Ladestation für ein Aufladen mit Gleichstrom aufgeladen, so sind grundsätzlich Stellplätze für ein Elektrofahrzeug nahe bei einer Ladeeinrichtung der Ladestation vorgesehen, da eine solche Ladestation für einen solchen Anwendungsfall konzipiert worden ist. Anders sieht es im Fall von Steckdosen für einen H aushalt aus. Der Absta nd zwischen einer Parkmöglichkeit für ein Elektrofahrzeug und einer Steckdose für Wechselstrom ist regel mäßig größer im Vergleich zu dem Fall einer Ladestation für ein Aufladen mit Gleichstrom. Bei dieser Ausfü hrungsform kann die Länge des Ladekabels der Ladeeinrichtung des Elektrofahrzeugs vorteilhaft relativ kurz sein und zwar a bgestim mt auf übliche Abstände, die es im Fall eines Aufladens an einer Ladestation für Gleichstrom zu überbrücken gilt. Dank des Adapters mit einem eigenen Elektrokabel können dennoch größere Abstände überbrückt werden, wenn das Elektrofahrzeug a n einer ha ushaltsüblichen Steckdose mit Wechselstrom aufgeladen werden soll . The adapter comprises, in an embodiment, an electrocardi whose ends are provided with electrical connectors. If a charging station is charged for charging with direct current, parking spaces for an electric vehicle are generally provided close to a charging device of the charging station, since such a charging station has been designed for such an application. The situation is different in the case of sockets for a H-content. The distance between a parking space for an electric vehicle and an AC outlet is usually larger compared to the case of a charging station for DC charging. In this embodiment, the length of the charging cable of the charging device of the electric vehicle can be advantageously relatively short and a bgestim mt to usual distances, which it applies in the case of charging at a charging station for DC to be bridged. Thanks to the adapter with its own electric cable, however, larger distances can be bridged if the electric vehicle is to be charged to a conventional mains socket with alternating current.
Die beiden elektrischen Steckverbinder des Adapters an den beiden Kabelenden sind in einer Ausfü hrungsform nicht zueinander kompatibel . Der eine elektrische Steckverbinder des Adapters, der mit den Wechselstromkonta kten der Ladeeinrichtung des Elektrofahrzeugs verbunden werden kann, kann bei dieser Ausführungsform nicht mit dem anderen elektrischen Steckverbinder verbunden werden, der mit einer haushaltsüblichen Steckdose für ein Aufladen mit Wechselstrom verbu nden werden ka nn. Erst der Adapter ermöglicht bei dieser Ausfü hrungsform das Aufladen an einer entsprechenden haushaltsüblichen Steckdose für Wechselstrom. Der Adapter ist vorzugsweise so eingerichtet ist, dass dieser mit einer Mehrzahl unterschiedlicher Steckdosen für Wechselstrom verbunden werden kann. Unterschiedliche Steckdosen meint unterschiedliche Typen, die untereinander nicht kompatibel sind. Zum Beispiel ist eine haushaltsübliche Steckdose in den USA ein anderer Typ als eine haushaltsübliche Steckdose in Deutschland. Ein Adapter weist daher in einer Ausführungsform einen elektrischen Steckverbinder auf, der an eine haushaltsübliche Steckdose in einem Land, z. B. in den USA angeschlossen werden kann sowie einen anderen elektrischen Steckverbinder, der an eine haushaltsübliche Steckdose in einem anderen Land mit einem anderen Steckdosentyp, zum Beispiel in Deutschland angeschlossen werden kann. The two electrical connectors of the adapter at the two ends of the cable are not compatible with each other in one embodiment. The one electrical connector of the adapter, which can be connected to the Wechselstromkonta kts the charging device of the electric vehicle, can not be connected in this embodiment with the other electrical connector, which can be connected to a household standard socket for charging with alternating current ken. Only the adapter allows in this embodiment, the charging at a corresponding common household AC outlet. The adapter is preferably arranged so that it can be connected to a plurality of different sockets for alternating current. Different sockets means different types that are not compatible with each other. For example, a standard household outlet in the US is a different type than a standard household outlet in Germany. An adapter therefore, in one embodiment, has an electrical connector which is connected to a standard household power outlet in a country, e.g. B. in the US can be connected and another electrical connector that can be connected to a standard household power outlet in another country with a different type of socket, for example in Germany.
Das Ladekabel der Ladeeinrichtung ist in einer Ausführungsform unlösbar und damit vorteilhaft unverlierbar mit der Ladeeinrichtung des Elektrofahrzeugs verbunden. Damit ist gemeint, dass dieses Ladekabel nicht ohne Werkzeug entfernt werden kann. Die Erfindung umfasst aber auch den Fall, dass das Ladekabel der Ladeeinrichtung aufgrund einer entsprechenden elektrischen Steckverbindung von der Ladeeinrichtung bzw. dem zugehörigen Elektrofahrzeug abgenommen werden kann, ohne dafür Werkzeug einsetzen zu müssen. The charging cable of the charging device is in one embodiment insoluble and thus advantageously permanently connected to the charging device of the electric vehicle. This means that this charging cable can not be removed without tools. However, the invention also includes the case that the charging cable of the charging device can be removed due to a corresponding electrical connector from the charging device or the associated electric vehicle, without having to use tools.
Das Ladekabel der Ladeeinrichtung kann vorzugsweise auf einer drehbaren Trommel aufgewickelt und wieder abgewickelt werden, um dieses geeignet lagern zu können. Bei dieser Ausführungsform ist das Ladekabel der Ladeeinrichtung in der Regel nicht lösbar mit der Trommel verbunden. The charging cable of the charging device can preferably be wound on a rotatable drum and unwound again in order to be able to store it properly. In this embodiment, the charging cable of the charging device is usually not detachably connected to the drum.
Ein elektrischer Steckverbinder der Ladeeinrichtung des Elektrofahrzeugs umfasst zwei elektrische Kontakte für das Aufladen mit Gleichstrom sowie wenigstens zwei, vorzugsweise drei, besonders bevorzugt fünf elektrische Kontakte für das Aufladen mit Wechselstrom. Im Fall von fünf elektrischen Wechselstromkontakten ist ein beschleunigtes Aufladen mit Drehstrom vorteilhaft möglich . Die elektrischen Kontakte für ein Aufladen mit Wechselstrom weisen vorzugsweise einen geringeren Durchmesser als die Konta kte für das Aufladen mit Gleichstrom auf, da für ein Aufladen mit Gleichstrom in der Regel die Ü bertragung von höheren elektrischen Leistu ng en vorgesehen ist. Der elektrische Steckverbinder der Ladeeinrichtung umfasst darü ber hinaus in einer Ausführungsform mindestens zwei elektrische Kontakte für Steuerströme, um ein Aufladen elektronisch zu steuern. Die elektrischen Kontakte für Steuerströme weisen vorzugsweise den geringsten Durchmesser im Vergleich zu den übrigen elektrischen Kontakten auf . I n der Regel sind die elektrischen Wechselstromkontakte zwischen den Gleichstromkontakten und den elektrischen Kontakten für Steuerströme angeordnet. An electrical connector of the charging device of the electric vehicle comprises two electrical contacts for charging with direct current and at least two, preferably three, more preferably five electrical contacts for charging with alternating current. In the case of five AC electrical contacts is an accelerated charging with three-phase advantageously possible. The electrical contacts for charging with alternating current preferably have a smaller diameter than the Konta kte for charging with direct current, since for charging with direct current usually the transfer of higher electrical Leistungsu ng en is provided. In one embodiment, the electrical connector of the charging device includes at least two electrical contacts for control currents to electronically control charging. The electrical contacts for control currents preferably have the smallest diameter compared to the other electrical contacts. In general, the AC electrical contacts are arranged between the DC contacts and the electrical contacts for control currents.
Der Adapter kan n grundsätzlich elektrisch nur mit zu mindest zwei Wechselstromkontakten verbunden werden, nicht aber mit den elektrischen Kontakten für Steuerströme sowie den Gleichstromkontakten. Das Verbinden des Adapters mit korrespondierenden elektrischen Steckverbindern ist dann mit relativ geringe m Kraftaufwand möglich. In principle, the adapter can only be electrically connected to at least two AC contacts, but not to the electrical contacts for control currents and the DC contacts. The connection of the adapter with corresponding electrical connectors is then possible with relatively little m effort.
