Description
Die Erfindung betrifft eine induktive Ladevorrichtung für das Laden einer Fahrzeugbatterie und ein Fahrzeug.The invention relates to an inductive charging device for charging a vehicle battery and a vehicle.
Für ein induktives Laden eines elektrisch angetriebenen Fahrzeuges wird eine induktive Ladestation verwendet.For an inductive charging of an electrically driven vehicle, an inductive charging station is used.
Beim induktiven Laden eines elektrisch angetriebenen Fahrzeugs, insbesondere Kraftfahrzeug, wird eine installierte Bodenspule in einer Bodeneinheit verwendet, die über eine induktive Wirkung Energie an eine zweite Spule im Fahrzeug überträgt, um beispielsweise eine Batteriesystem für den Antrieb des Fahrzeugs zu laden. Für den induktiven Ladevorgang ist es notwendig, dass die Position des Fahrzeugs erkannt wird, damit dieses positionsgenau an der Bodenspule positioniert wird.When inductive charging an electrically driven vehicle, in particular motor vehicle, an installed bottom coil is used in a ground unit, which transmits an inductive effect energy to a second coil in the vehicle to load, for example, a battery system for driving the vehicle. For the inductive charging process, it is necessary that the position of the vehicle is detected, so that this position is positioned accurately on the bottom coil.
Allerdings stellt die Positionsdetektion des Fahrzeugs relativ zur Bodenspule einer induktiven Ladeinheit eine Herausforderung dar. Ein Grund hierfür ist, dass Positionssignale über bekannte Verfahren, z.B. das „Magnetic Vectoring“, erheblichen prinzipiell bedingten Störungen im physikalischen Messprinzip unterliegen. Das Fahrzeug an sich, die Karosserie, die Lenkung, die Stoßdämpfer, etc. stören magnetisch basierte Positionsdetektionsverfahren und bieten somit nur unzureichende Positioniermöglichkeiten.However, the position detection of the vehicle relative to the bottom coil of an inductive charging unit poses a challenge. One reason for this is that position signals are transmitted via known methods, e.g. Magnetic vectoring, subject to considerable principle-related interference in the physical measurement principle. The vehicle itself, the bodywork, the steering, the shock absorbers, etc. interfere with magnetically based position detection methods and thus offer only insufficient positioning possibilities.
Es ist Aufgabe der vorliegenden Erfindung eine Lösung vorzuschlagen, die beim induktiven Laden auf einfache Weise eine Positionsdetektion ermöglicht.It is an object of the present invention to propose a solution that enables a simple position detection during inductive charging.
Die Aufgabe der Erfindung wird mit dem Gegenstand des Anspruchs 1 und mit dem Gegenstand des Anspruchs 4 gelöst.The object of the invention is achieved with the subject matter of
Die Aufgabe der Erfindung wird mit einer induktiven Ladestation für ein Laden eines Fahrzeugs aufweisend eine Fahrzeugspule gelöst. Hierbei weist die induktive Ladestation eine Bodenspule auf, wobei mit der Bodenspule eine induktive Kopplung zwischen der Bodenspule und der Fahrzeugspule hervorrufbar ist. Ferner ist vorgesehen, dass die induktive Ladestation eine Kopplungsmesseinrichtung aufweist, mit der eine Kopplungsstärke zwischen der Bodenspule und der Fahrzeugspule messbar ist, wobei die Kopplungsstärke als Indikator für eine Positionierung des Fahrzeugs an der induktiven Ladestation verwendbar ist.The object of the invention is achieved with an inductive charging station for charging a vehicle having a vehicle coil. In this case, the inductive charging station on a bottom coil, with the bottom coil, an inductive coupling between the bottom coil and the vehicle coil hervorufbar is. It is further provided that the inductive charging station has a coupling measuring device with which a coupling strength between the bottom coil and the vehicle coil can be measured, wherein the coupling strength can be used as an indicator for a positioning of the vehicle at the inductive charging station.
Ferner wird die Aufgabe der Erfindung mit einem Fahrzeug gelöst. Hierbei weist das Fahrzeug eine Fahrzeugspule auf zum induktiven Laden eines elektrischen Energiespeichers des Fahrzeugs an einer induktiven Ladestation. Ferner ist vorgesehen, dass das Fahrzeug eine Kopplungsmesseinrichtung aufweist, mit der eine Kopplungsstärke zwischen einer Bodenspule der induktiven Ladestation und der Fahrzeugspule messbar ist, wobei die Kopplungsstärke als Indikator für eine Positionierung des Fahrzeugs an der induktiven Ladestation verwendbar ist.Furthermore, the object of the invention is achieved with a vehicle. In this case, the vehicle has a vehicle coil for inductive charging of an electrical energy storage device of the vehicle at an inductive charging station. It is further provided that the vehicle has a coupling measuring device with which a coupling strength between a bottom coil of the inductive charging station and the vehicle coil can be measured, wherein the coupling strength can be used as an indicator for a positioning of the vehicle at the inductive charging station.
Es wird demnach mit einer Kopplungsmesseinrichtung, installiert in der Bodenplatte und/oder im Fahrzeug, um eine Kopplungsstärke zwischen einer Bodenspule und einer Fahrzeugspule zu messen. Hierbei wird vorgesehen, dass die Kopplungsstärke als Indikator für eine Positionierung des Fahrzeugs an der induktiven Ladestation verwendbar ist. Somit wird die Kopplungsstärke als eine Messgröße dazu verwendet, um auf eine Positionierung des Fahrzeugs an bzw. auf der Bodenplatte zu schließen. Auf diese Weise können weitere Sensoren zur Positionsmessung vermieden werden, was die Positionsmessung und die Einrichtungen zur Positionsmessung an sich vereinfacht.It is therefore with a coupling measuring device installed in the bottom plate and / or in the vehicle to measure a coupling strength between a bottom coil and a vehicle coil. It is provided here that the coupling strength can be used as an indicator for a positioning of the vehicle at the inductive charging station. Thus, the coupling strength is used as a measure to conclude positioning of the vehicle on the floor panel. In this way, further sensors for position measurement can be avoided, which simplifies the position measurement and the means for measuring position itself.
Ferner kann mit Vorteil in einer Ausführungsform vorgesehen werden, dass die Kopplungsmesseinrichtung mit einer Steuervorrichtung in Wirkverbindung steht. Hierbei kann die Kopplungsmesseinrichtung an einer beliebigen Stelle im Fahrzeug und/oder in oder an der Ladestation installiert sein. Es ergibt sich beispielsweise der Vorteil, dass erst bei genauer Positionierung der beiden Energiespulen übereinander ein Ladevorgang eingeleitet wird, indem die Steuervorrichtung eine Ladefreigabe signalisiert bzw. einer Ladefreigabevorrichtung eine Freigabe zum Laden erteilt. Dies macht das induktive Laden effektiver und sicherer. Die Ladefreigabevorrichtung kann als elektrisch und/oder mechanisch ausgestaltet sein. Beispielsweise kann sie mechanisch als elektrischer Schalter mit Schaltkontakten bereitgestellt werden. Ferner kann sie in elektrischer Form Freigabesignal für die Ladestation zur Einleitung des Ladevorgangs bereitgestellt werden. Furthermore, it can advantageously be provided in one embodiment that the coupling measuring device is in operative connection with a control device. Here, the coupling measuring device can be installed anywhere in the vehicle and / or in or on the charging station. For example, there is the advantage that a charging process is initiated only when the two energy coils are positioned one above the other by the control device signaling a charge release or granting a charge release device a charge for charging. This makes inductive charging more effective and safer. The charge release device may be configured as electrically and / or mechanically. For example, it can be provided mechanically as an electrical switch with switching contacts. Further, it may be provided in electrical form enable signal for the charging station to initiate the charging process.
In vorteilhafterweise wird in einem Ausführungsbeispiel vorgesehen, dass die Wirkverbindung eine drahtlose Kommunikationsverbindung ist. Auf diese Weise ist es einfach möglich, zwischen der Kopplungsmesseinrichtung und der Steuereinrichtung Signale und/oder Daten auszutauschen, ohne dass darauf Rücksicht genommen werden muss, an welchem Installationsort die Steuereinrichtung bereitgestellt wird. Diese kann beispielsweise im Fahrzeug, an oder in der Ladestation oder an einem anderen Ort installiert sein, beispielsweise in einer Serviceeinrichtung in einem Gebäude.In one embodiment, it is advantageously provided that the active connection is a wireless communication connection. In this way, it is easily possible to exchange signals and / or data between the coupling measuring device and the control device without having to take into account at which installation location the control device is provided. This may for example be installed in the vehicle, on or in the charging station or in another location, for example in a service facility in a building.

Ferner ist im vorliegenden Ausführungsbeispiel sowohl die Ladestation
Insgesamt wird demnach vorgeschlagen, eine Messung der magnetischen Kopplung der beiden Spulen auf Boden- und Fahrzeugseite durchzuführen anstatt die Position zweier Ladeeinheiten, insbesondere die Fahrzeugposition relativ zur Ladestation
Insgesamt ergeben sich beispielsweise Vorteile, dass auf ein aufwendiges, kostentreibendes und fehleranfälliges Positioniersystem verzichtet werden kann. Die Energiespulen
