Description
Die Erfindung beschreibt eine Vorrichtung zum elektrischen Laden von elektrisch angetriebenen Straßenfahrzeugen, insbesondere mehrspurigen Fahrzeugen wie Elektro-PKW, leichte Nutzfahrzeuge, etc.The invention describes a device for the electrical charging of electrically driven road vehicles, in particular multi-lane vehicles such as electric cars, light commercial vehicles, etc.
Üblicherweise werden die Traktionsbatterien von elektrisch angetriebenen Straßenfahrzeugen aufgeladen, indem das Fahrzeug unmittelbar an einer Ladestation platziert wird und anschließend mittels eines Ladekabels die elektrische Verbindung zwischen dem Fahrzeug und der Ladevorrichtung hergestellt wird. Das Ladekabel, welches während der Fahrt im Fahrzeug untergebracht ist, wird zum Laden herausgeholt und in entsprechende Buchsen in der Ladevorrichtung und dem Fahrzeug eingesteckt. Der Leitungs-Durchmesser und das Gewicht des Kabels hängen von der zu übertragenden Stromstärke ab und erreichen bei einem Ladestrom von 32 Ampere bereits Werte, welche die Handhabbarkeit und den Bedienungskomfort stark einschränken.Typically, the traction batteries of electrically powered road vehicles are charged by the vehicle is placed directly at a charging station and then by means of a charging cable, the electrical connection between the vehicle and the charger is made. The charging cable, which is housed in the vehicle while driving, is taken out for loading and plugged into corresponding sockets in the charging device and the vehicle. The cable diameter and the weight of the cable depend on the current to be transmitted and reach at a charging current of 32 amps already values that severely limit the handling and ease of use.
Eine andere elektrische Lade-Variante arbeitet nach dem Prinzip des induktiven Ladens. Dazu ist im Boden der Ladestation eine (Kupfer-)Spule eingelassen, welche ein elektrisches Feld erzeugt. Das Fahrzeug weist im Wagenboden eine zu induzierende Spule auf, in der durch die Induktion ein entsprechender Strom zum Laden der Batterie fließt. Bei dieser Art des elektrischen Ladens entfallt zwar das Einstecken des Kabels, jedoch hat das Verfahren eine Reihe anderer Nachteile: Es weist Wirkungsgrad-Verluste auf; die möglichen Spulengrößen im PKW erlauben nur relativ geringe Ladeströme; die EMV-Verträglichkeit ist nicht sicher geklärt; der Komponentenaufwand und damit die Kosten relativ hoch.Another electric charging variant works on the principle of inductive charging. For this purpose, a (copper) coil is embedded in the bottom of the charging station, which generates an electric field. The vehicle has in the car floor a coil to be induced, in which a corresponding current flows through the induction for charging the battery. While this type of electrical charging eliminates the insertion of the cable, but the process has a number of other disadvantages: It has loss of efficiency; the possible coil sizes in the car allow only relatively low charging currents; the EMC compatibility is not clarified sure; the component costs and thus the costs relatively high.
Eine Ideallösung wäre eine direkte Kontaktierung zwischen einem fahrzeugseitigen Stecker und einer entsprechenden Buchse auf Seiten der Ladevorrichtung. Als eigentliche Herausforderung bei einer solchen Lösung gilt es, die beiden Kontaktelemente, d. h. den Stecker vom Fahrzeug und die Buchse der Ladevorrichtung, aufeinander auszurichten, so dass die beiden Kontakte automatisch miteinander verbindbar sind und bei Annäherung des Fahrzeuges automatisch eine elektrische Verbindung hergestellt werden kann. Vorteilhaft wäre es außerdem, wenn das gesamte Kontaktsystem unterhalb des Fahrzeugbodens, d. h. Im Bereich zwischen Fahrzeugboden und Fahrbahn angeordnet wäre.An ideal solution would be a direct contact between a vehicle-side connector and a corresponding socket on the side of the charging device. The real challenge with such a solution is the two contact elements, d. H. align the plug of the vehicle and the socket of the charging device, so that the two contacts are automatically connected to each other and when the vehicle approaches an electrical connection can be made automatically. It would also be advantageous if the entire contact system below the vehicle floor, d. H. In the area between vehicle floor and roadway would be arranged.

Die hier vorgeschlagene Erfindung ermöglicht ein automatisches Verbinden mit der Ladestation und bietet gleichzeitig die oben genannten Vereinfachungen. Sie kommt ohne zusätzliche Positionierungselemente aus und löst die Ausrichtungsproblematik durch geeignete Führungsmechanismen auf einfachste Weise. Gleichzeitig wird die Wahrnehmung des Fahrers beim „Treffen” und Einfahren in die Ladevorrichtung verbessert.The invention proposed here allows automatic connection to the charging station and at the same time provides the above-mentioned simplifications. It does not require additional positioning elements and solves the alignment problem in the simplest way by means of suitable guide mechanisms. At the same time the perception of the driver when "meeting" and entering the loader is improved.
Die Vorrichtung und mögliche Ausgestaltungen sind im Folgenden beschrieben:

In einer weiteren Variante kann das ladevorrichtungsseitige Kontaktelement (
Die Freischaltung, Anmeldung, Authentifizierung für den Ladevorgang kann analog zu herkömmlichen Ladesystemen erfolgen. Es ist vorgesehen, in einer weiteren Ausführung das System mit einer auf Navigationsdaten basierenden Steuerung auszustatten. Hierbei erkennt das Fahrzeug anhand der Navigationsdaten seinen Standort und kann das System automatisch aktivieren und die Ladekontakte ausfahren, wenn sich das Fahrzeug z. B. der heimischen Garage oder einem dem Navigationssystem bekannten Ladepunkt nähert.The activation, registration, authentication for the charging process can be carried out analogously to conventional charging systems. It is envisaged to equip the system with a navigation-data-based control in a further embodiment. Here, the vehicle recognizes its location based on the navigation data and can automatically activate the system and extend the charging contacts when the vehicle z. B. the local garage or a navigation system known charging point approaches.
Das System kann auch mit den bekannten herkömmlichen Steckern (Schuko, CEE, 7-poliger Typ3-Stecker, Yazaki-Stecker, etc.) ausgestattet werden, wobei der jeweilige Stecker das Kontaktelement auf der einen Seite darstellt und die zugehörige Kupplung bzw. Buchse das Kontaktelement der anderen Seite darstellt. Führung, Ausrichtung, Fluchten, Einkuppeln und Kontaktieren geschieht analog der obigen Beschreibung.The system can also be equipped with the well-known conventional plugs (Schuko, CEE, 7-
Die Vorrichtung kann sowohl für das Laden mit Gleichstrom, als auch für das Laden mit Wechselstrom oder Drehstrom (Mehrphasen-Wechselstrom) eingesetzt werden.The device can be used both for direct current charging and for charging with alternating current or three-phase current (multiphase alternating current).
Denkbar ist auch, das ladevorrichtungsseitige Kontaktelement (
Für die Kontaktelemente sind verschiedene Ausführungs- und Gestaltungsvarianten denkbar: So sind Ausführungen denkbar, bei denen ein mit seiner Achse in Fahrtrichtung des Fahrzeuges angeordneter zylindrischer oder konischer Körper das fahrzeugseitige, einsteckende Element bildet und auf Ladevorrichtungsseite ein entsprechendes Gegenstück (Hohlzylinder bzw. Innenkonus). Die Kontakte können hierbei in mehreren Ringen axial hintereinander angeordnet sein. Denkbar ist auch ein senkrecht angeordneter Zylinder. Besonders vorteilhaft ist eine Ausgestaltung, bei der ein flaches, in etwa rechteckförmiges plattenförmiges Element das fahrzeugseitige Kontaktelement bildet, welches zum Laden nach unten aus dem Fahrzeug heraus fährt in Richtung Fahrbahnoberfläche (ähnlich dem Kiel eines Schiffes). Die schmale Seite zeigt hierbei in Fahrtrichtung. Der Abstand zur Fahrbahnoberfläche ist fest eingestellt und kann mit Hilfe von im Kontaktelement eingebauten Abstandswarnern überwacht und über eine geeignete Steuerung korrigiert werden, falls dies bei stark eingefedertem Fahrzeug nötig sein sollte. Die elektrischen Kontakte sind hierbei jeweils an den Seitenflächen dieses kielförmigen Kontaktelementes angebracht. Die Ladevorrichtung bildet das entsprechende Gegenstück und weist einen entsprechenden Spalt auf, in den das fahrzeugseitige Kontaktelement (
Die Vorrichtung gemäß dieser Ausgestaltung kann dadurch noch erweitert werden, dass die elektrischen Kontakte auf Ladevorrichtungsseite (
Die Erfindung bietet gegenüber dem konventionellen Laden eine Reihe von Vorzügen:
Das Laden gestaltet sich äußerst einfach. Das Hantieren mit schweren Kabeln und unhandlichen Steckern entfällt ebenso wie frei hängende und frei zugängliche Kabel. Die Verschmutzungs-, Verletzungs- und Vandalismusgefahren werden deutlich reduziert.The invention offers a number of advantages over conventional loading:
The loading is very simple. The handling of heavy cables and bulky plugs is no longer necessary as well as freely suspended and freely accessible cables. The risk of contamination, injury and vandalism are significantly reduced.
Es können auch kurze Parkzeiten effektiv zum Nachladen genutzt werden; ebenso kann die Ladezeit deutlich bequemer zum Telefonieren, Arbeiten, etc. genutzt werden, da ein Aussteigen nicht erforderlich ist.Short parking times can also be effectively used for reloading; Similarly, the charging time can be used much more convenient for telephoning, working, etc., since a disembarkation is not required.
Es gibt keine Probleme mit dem Anschließen der Ladekabel in enger Umgebung (z. B. Autoreisezug, Einzelgarage). Aufgrund des Wegfalls des Kabels lassen sich deutlich größere Ladeströme und damit geringere Ladezeiten realisieren.There are no problems with connecting the charging cables in close proximity (eg car train, single garage). Due to the omission of the cable significantly larger charging currents and thus lower charging times can be realized.
Aus Sicht der Fahrzeughersteller ist es ein großer Vorteil, wenn die Einspeisung des Stromes an einer Stelle erfolgen kann, die sich nicht im sichtbaren Karosseriebereich befindet, und die gleichzeitig nicht im größeren Umfang in die Fahrzeugstruktur eingreift.From the perspective of the vehicle manufacturer, it is a great advantage if the supply of electricity can be done in a location that is not in the visible body area, and at the same time does not intervene to a greater extent in the vehicle structure.
Die Ausrichtung der Kontaktelemente zueinander (fahrzeugseitig zu ladevorrichtungsseitig) wird durch die Nutzung des Rades bzw. Reifens oder der Felge des Fahrzeuges als Ausrichtungselement vom Nutzer als sehr vorteilhaft empfunden, da zum einen auch ohne Sichtkontakt ein Gefühl für die Position des Rades vorhanden ist (aus verschiedenen Fahrsituationen wie Einparken, Einfahren in Waschanlagen, Auffahren auf Bordsteine etc.). Zum anderen ist der Reifen ein besonders unempfindliches Element am Fahrzeug, mit dem eine Berührung eines festen Gegenstandes, wie es die Ladevorrichtung darstellt, nicht als unbehaglich oder mit Beschädigungsgefahr verbunden wahrgenommen wird.The orientation of the contact elements to each other (vehicle side to the charger side) is perceived by the use of the wheel or tire or the rim of the vehicle as an alignment element by the user as very beneficial because on the one hand, even without visual contact, a sense of the position of the wheel is present (from various driving situations such as parking, driving into washing facilities, driving on curbs, etc.). On the other hand, the tire is a particularly insensitive element on the vehicle, with which a touch of a solid object, as it represents the charging device is not perceived as uncomfortable or with the risk of damage.
