Description

Elektrische Einrichtung zum Vorwärmen eines Antriebsmotors eines Kraftfahrzeugs und/oder zum Vorklimatisieren eines Fahrzeuginnenraums im Stillstand des Kraftfahrzeugs Die Erfindung betrifft eine elektrische Einrichtung zum Vorwärmen eines Antriebsmotors eines Kraftfahrzeugs und/oder zum Vorklimatisieren eines Fahrzeuginnenraums im Stillstand des Kraftfahrzeugs, wobei die zum Betrieb der Einrichtung erforderliche elektrische Energie von einer ortsfesten  The invention relates to an electrical device for preheating a drive motor of a motor vehicle and / or for preclimatization of a vehicle interior when the motor vehicle is at a standstill, wherein the time required for the operation of the device electrical energy from a stationary
Versorgungsstation mittels einer elektrischen Kopplungsvorrichtung zum Kraftfahrzeug hin übertragen wird. Supply station is transmitted by means of an electrical coupling device to the motor vehicle.
Einrichtungen zur Vorwärmung von Verbrennungsmotoren sind seit langem bekannt. So können Standheizungen in der Regel nicht nur zur Vorwärmung des Fahrgastraums, sondern auch zur Vorwärmung des Verbrennungsmotors eingesetzt werden. Einrichtungen zur Vorwärmung von Verbrennungsmotoren sind aber keinesfalls Standard. Dies liegt zum einen an den damit Facilities for preheating internal combustion engines have long been known. As a rule, parking heaters can be used not only to preheat the passenger compartment, but also for preheating the engine. However, devices for preheating internal combustion engines are by no means standard. This is due to the one with it
verbundenen Zusatzkosten. Zum anderen ist eine Vorwärmung des associated additional costs. On the other hand, a preheating of the
Verbrennungsmotors in warmen Ländern bzw. Regionen weniger geboten als dies bei Fahrzeugen der Fall ist, die in„Kaltländern" betrieben werden. Combustion engine in warm countries or regions less than is the case with vehicles that are operated in "cold countries".
Um im Stillstand befindliche Fahrzeuge optimal temperieren zu können, sind derzeit verschiedene Vorrichtungen und Verfahren bekannt. So offenbart die Offenlegung DE 197 31 071 A1 eine Anlage zum Temperieren des In order to optimally temper vehicles at standstill, various devices and methods are currently known. Thus, the disclosure DE 197 31 071 A1 discloses a system for tempering the
Fahrzeuginnenraums eines Kraftfahrzeugs im Stillstand, bei dem die im Fahrzeug noch vorhandene Restwärme einer Wärmequelle und Restkälte einer Kältequelle genutzt wird. Vehicle interior of a motor vehicle at a standstill, in which the residual heat remaining in the vehicle of a heat source and residual cold of a cold source is used.
Da die Nutzung von Restwärme und/oder Restkälte nur möglich ist, wenn die dafür genutzten Wärmequellen und/oder Kältequellen sich in einem Zustand befinden, in dem sie Wärme und/oder Kälte abgeben können, in der Regel also unmittelbar nach (längerem) Betrieb des Kraftfahrzeugs, sind derartige Systeme oft nicht ausreichend, um eine optimale Temperierung des Since the use of residual heat and / or residual refrigeration is only possible if the heat sources and / or cooling sources used for this purpose are in a state in which they can give off heat and / or cold, as a rule ie immediately after (longer) operation of the motor vehicle, such systems are often not sufficient to optimal temperature of the
Fahrzeuginnenraums im Stillstand zu ermöglichen. Neben den genannten Vorrichtungen zum Temperieren des Fahrzeuginnenraums im Stillstand werden zum Heizen oder Kühlen des Fahrzeugs im Stillstand Zuheiz- bzw. Standheizgeräte bzw. elektrisch angetriebene Kühleinrichtungen verwendet, die ihre Energie von einer ortsfesten Versorgungsstation erhalten, von der diese mittels einer elektrischen Kopplungsvorrichtung zum Kraftfahrzeug hin übertragen wird. Die dabei verwendete Kopplungsvorrichtung ist in der Regel durch ein an der Versorgungsstation vorhandenes Kabel gebildet, welches mit einem Steckverbinder versehen ist, der zur elektrischen Kontaktierung eines entsprechend ausgebildeten Gegensteckverbinders an dem Kraftfahrzeug vorgesehen ist. Auf Parkplätzen von Firmen, Behörden, aber auch im privaten Bereich sind als Bestandteile der Versorgungsstation beispielsweise Pfähle installiert, die diese elektrischen Anschlussvorrichtungen beinhalten. Oft wird nach Benutzung solcher Vorrichtungen jedoch vergessen, das Allow vehicle interior at a standstill. In addition to the said devices for controlling the temperature of the vehicle interior at standstill Zuheiz- or parking heaters or electrically powered cooling devices are used to heat or cool the vehicle, which receive their energy from a stationary supply station, of which these by means of an electrical coupling device to the motor vehicle is transmitted. The coupling device used in this case is usually formed by an existing at the supply station cable, which is provided with a connector which is provided for electrically contacting a correspondingly formed mating connector on the motor vehicle. In parking lots of companies, authorities, but also in the private sector, for example, piles are installed as components of the supply station, which include these electrical connection devices. Often, however, after using such devices forget that
Verbindungskabel zu entfernen und es wird über weite Strecken mitgezogen. Darüber hinaus ist das Stecken und Entfernen des Kabels mit Aufwand verbunden. Remove connection cable and it is pulled along over long distances. In addition, the insertion and removal of the cable is associated with effort.

Wenn dazu die Ankoppelvorrichtung der ortsfesten Versorgungsstation an das Kraftfahrzeug angefügt ist, bilden die stationäre elektrische Wicklung der Versorgungsstation und die fahrzeugseitige elektrische Wicklung gemeinsam einen Transformator aus, wobei die stationäre elektrische Wicklung die Funktion der Primärwicklung und die fahrzeugseitige elektrische Wicklung die Funktion der Sekundärwicklung des Transformators erfüllen. Die elektrischen Wicklungen können dabei beispielsweise als Luftspulen und/oder als Spulen mit magnetischem Kern ausgeführt sein, wobei Form und Querschnitt sowohl der Spulen als auch der ggf. vorhandenen Kerne an die jeweiligen When the docking device of the stationary supply station is attached to the motor vehicle, the stationary electrical winding of the supply station and the vehicle-side electrical winding together form a transformer, wherein the stationary electrical winding, the function of the primary winding and the vehicle-side electrical winding, the function of the secondary winding of the transformer fulfill.

Gemäß einer bevorzugten Ausführungsform der Erfindung ist die According to a preferred embodiment of the invention is the
fahrzeugseitige elektrische Wicklung hinter einem Kennzeichenschild des Kraftfahrzeugs angeordnet. Vorteilhaft bei dieser Ausgestaltung ist, dass amtliche Kennzeichenschilder im allgemeinen an standardisierten Anbauorten angeordnet sind. So sind bei den meisten Kraftfahrzeugen die Kennzeichenschilder mittig an der Fahrzeugfront und am Fahrzeugheck befestigt, wobei die Mindestanbauhöhen über der Fahrbahn vorgeschrieben sind. Aber auch bei abweichender Positionierung sind die Kennzeichenschilder an der Fahrzeugkarosserie immer leicht auffindbar. Bei Kraftfahrzeugen, bei denen erfindungsgemäß das Vehicle-side electrical winding arranged behind a license plate of the motor vehicle. An advantage of this design is that official license plates are generally located at standardized locations. Thus, in most motor vehicles, the license plates are mounted centrally on the front of the vehicle and on the rear of the vehicle, the minimum mounting heights are prescribed above the roadway. But even with different positioning the license plates are always easy to find on the vehicle body. In motor vehicles, according to the invention the
fahrzeugseitige Transformatorteil hinter dem vorderen oder dem hinteren Kennzeichenschild angeordnet ist, ist somit auch die Anfügesteile für die Ankoppelvorrichtung der Versorgungsstation unmittelbar zu lokalisieren. vehicle-side transformer part is arranged behind the front or the rear license plate, thus the Anfügesteile for the coupling device of the supply station is to be located immediately.
Das Kennzeichenschild besteht entweder vollständig oder aber zum größten Teil aus einem elektrisch nicht leitenden oder schlecht leitenden Material, da hierdurch Wirbelstromverluste bei der induktiven Energieübertragung gering gehalten werden können. Vorzugsweise besteht das Kennzeichenschild aus einem Kunststoffmaterial, wobei aber auch die Verwendung anderer elektrisch nicht oder nur gering leitender Materialien oder Materialkombinationen als Werkstoff in Frage kommt. Die Ankoppelvorrichtung mit der stationären elektrischen Wicklung der Versorgungsstation braucht nur von außen an das Kennzeichenschild angelegt zu werden, um induktiv mit der fahrzeugseitigen elektrischen Wicklung verbunden zu werden. Da die durch die elektrischen Wicklungen gebildeten Transformatorteile dann nur durch das relativ dünnwandige Kennzeichenschild getrennt sind, kann die Energieübertragung mit einem sehr guten Wirkungsgrad erfolgen. The license plate consists either completely or for the most part of an electrically non-conductive or poorly conductive material, as this eddy current losses in the inductive energy transfer can be kept low. Preferably, the license plate is made of a plastic material, but also the use of other electrically or only slightly conductive materials or material combinations as a material in question. The coupling device with the stationary electric winding of the supply station need only be applied from the outside to the license plate to be inductively connected to the vehicle-side electrical winding. Since the transformer parts formed by the electrical windings are then separated only by the relatively thin-walled license plate, the energy transfer can be done with a very good efficiency.
