Description
Die Erfindung betrifft ein induktives Energieübertragungssystem zur Übertragung elektrischer Energie von einer primärseitigen, insbesondere stationär angeordneten, Spulenanordnung hin zu einer sekundärseitigen an einem Fahrzeug angeordneten Spulenanordnung, wobei die primärseitige und die sekundärseitige Spulenanordnung jeweils mindestens eine Wicklung und jeweils mindestens eine Ferritanordnung aufweisen, wobei die primärseitige Ferritanordnung eine Länge parallel zur Längserstreckung der Fahrbahn und eine Breite quer zur Längserstreckung der Fahrtbahn aufweist und die sekundärseitige Ferritanordnung eine Länge parallel zur Fahrzeuglängsachse und eine Breite quer zur Fahrzeuglängsachse aufweist.The invention relates to an inductive energy transmission system for transmitting electrical energy from a primary-side, in particular stationarily arranged, coil arrangement towards a secondary coil arrangement arranged on a vehicle, the primary-side and the secondary-side coil arrangement each having at least one winding and at least one ferrite arrangement, the primary-side Ferrite has a length parallel to the longitudinal extent of the road and a width transverse to the longitudinal extent of the trajectory and the secondary-side ferrite has a length parallel to the vehicle longitudinal axis and a width transverse to the vehicle longitudinal axis.
Eine aus dem Stand der Technik bekannte gattungsgemäße Vorrichtung ist in
Es ist auch möglich, dass die primärseitige Spulenanordnung von ihrer Breite und Länge größer ausgebildet ist als die sekundärseitige Spulenanordnung, wobei die sekundärseitige und primärseitige Spulenanordnung dabei in der Regel das gleiche Seitenverhältnis von Länge zu Breite aufweisen und die gleiche Form haben.It is also possible for the primary-side coil arrangement to be larger in its width and length than the secondary-side coil arrangement, the secondary-side and primary-side coil arrangement generally having the same aspect ratio of length to width and having the same shape.
Eine optimale induktive Energieübertragung ergibt sich stets dann, wenn die sekundärseitige Spulenanordnung exakt zentrisch über der primärseitigen Spulenanordnung positioniert wird. Da eine optimale Ausrichtung der primär- und sekundärseitigen Spulenanordnungen in der Praxis jedoch meist nicht zu realisieren ist, ist die primärseitige Spulenanordnung in der Regel sowohl breiter als auch länger dimensioniert als die sekundarseitige Spulenanordnung.Optimal inductive energy transfer always results when the secondary-side coil arrangement is positioned exactly centrically above the primary-side coil arrangement. Since optimal alignment of the primary and secondary coil arrangements in practice, however, is usually not feasible, the primary-side coil assembly is usually both wider and longer dimensioned as the secondary coil arrangement.
Je kleiner der Abstand zwischen der primärseitigen und der sekundärseitigen Spulenanordnung zueinander ist, desto besser ist die Kopplung und desto verlustärmer ist damit die Energieübertragung. Zur Verringerung des Abstandes kann entweder die primärseitige Spulenanordnung angehoben oder die sekundärseitige Spulenanordnung, meist in Form einer Pickup, abgesenkt werden. Bei derartigen Systemen, welche auch als Z-Mover bezeichnet werden, werden die primärseitigen und die sekundärseitigen Spulenanordnungen von ihrer Größe her gleich ausgebildet, wie es in
Aufgabe der vorliegenden Erfindung ist es daher, ein induktives Energieübertragungssystem bereitzustellen, welches eine gute Kopplung gewährleistet, selbst wenn das Fahrzeug in verschiedenen Positionen quer zur Fahrzeuglängsachse über der primärseitigen Spulenanordnung geparkt ist, wobei gleichzeitig die Materialkosten gering sind.Object of the present invention is therefore to provide an inductive energy transmission system, which ensures a good coupling, even if the vehicle is parked in different positions transverse to the vehicle longitudinal axis on the primary-side coil assembly, at the same time the material costs are low.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Breite der primärseitigen Ferritanordnung mindestens das 1,3 bis 6-fache der Breite der sekundärseitigen Ferritanordnung, besonders bevorzug das 1,5 bis 5-fache, beträgt, wobei insbesondere die Länge der primärseitigen Ferritanordnung maximal das 1,25-fache der Länge der sekundärseitigen Ferritanordnung ist.This object is achieved in that the width of the primary-side ferrite at least 1.3 to 6 times the width of the secondary-side ferrite, particularly preferably 1.5 to 5 times, in particular the length of the primary-side ferrite maximum 1.25 times the length of the secondary side ferrite assembly.
Weitere vorteilhafte Ausgestaltungen des induktiven Energieübertragungssystems gemäß Anspruch 1 ergeben sich durch die Merkmale der auf Anspruch 1 rückbezogenen Ansprüche 2 bis 11.Further advantageous embodiments of the inductive energy transmission system according to
Die Länge der primärseitigen Ferritanordnung ist vorteilhaft gleich dem 0,5 bis 1,25-fachen, besonders bevorzugt gleich dem 0,9 bis 1,2-fachen, der Länge der sekundärseitigen Ferritanordnung.The length of the primary-side ferrite is advantageously equal to 0.5 to 1.25 times, more preferably equal to 0.9 to 1.2 times, the length of the secondary-side ferrite.
Der Erfindung liegt der Erfindungsgedanke zugrunde, dass die primärseitige Spulenanordnung breiter als die sekundärseitige Spulenanordnung ausgebildet ist. Hierdurch kann sich die sekundärseitige Spulenanordnung quer zur Fahrtrichtung des Fahrzeuges in einem bestimmten Bereich zur stationär angeordneten primärseitigen Spulenanordnung befinden, wobei in diesem Bereich eine optimale Kopplung zwischen den beiden Spulenanordnungen gewährleistet ist. Eine optimale Kopplung wird somit nicht nur an einer bestimmten Parkposition sondern quer zur Fahrtrichtung in einem Bereich, dessen Breite sich aus der Differenz der Breiten der primär- und sekundärseitigen Spulenanordnungen ergibt, erreicht. Hierdurch vereinfacht sich das Positionieren des Fahrzeuges relativ zur stationären primärseitigen Spulenanordnung, da das Fahrzeug lediglich in Fahrtrichtung genau positioniert werden muss, was durch einfaches Vor- oder Zurückfahren des Fahrzeuges möglich ist und wozu keine Lenkbewegungen erforderlich sind. Sofern die primärseitige Spulenanordnung für die Energieübertragung angehoben bzw. die sekundärseitige Spulenanordnung abgesenkt wird, kann die entsprechende Hebe- bzw. Absenkvorrichtung einfach ausgestaltet werden, da auf eine Zustelleinrichtung quer zur Fahrtrichtung verzichtet werden kann.The invention is based on the concept of the invention that the primary-side coil arrangement is formed wider than the secondary-side coil arrangement. As a result, the secondary-side coil arrangement can be located transversely to the direction of travel of the vehicle in a specific area to the stationarily arranged primary-side coil arrangement, whereby an optimal coupling between the two coil arrangements is ensured in this area. An optimal coupling is thus not only at a certain Parking position but transverse to the direction of travel in a region whose width is the difference of the widths of the primary and secondary coil arrangements achieved. This simplifies the positioning of the vehicle relative to the stationary primary-side coil assembly, since the vehicle only needs to be accurately positioned in the direction of travel, which is possible by simply driving forwards or backwards of the vehicle and what for no steering movements are required. If the primary-side coil arrangement is raised for the transmission of energy or the secondary-side coil arrangement is lowered, the corresponding lifting or lowering device can be configured simply, since a delivery device can be dispensed with transversely to the direction of travel.
Die Breite der primärseitigen Ferritanordnung sollte mindestens so groß gewählt werden, wie die Summe aus dem Doppelten der geforderten seitlichen Positioniertoleranz und der Breite der sekundärseitigen Ferritanordnung. Unter der seitlichen Positioniertoleranz wird dabei der maximal erlaubte seitliche Versatz der sekundärseitigen Spulenanordnung relativ zur Mittellinie der primären Spulenanordnung verstanden. Das Fahrzeug darf somit nur derart geparkt werden, dass die sekundäre Spulenanordnung stets sich noch mit ihrer vollständigen Breite oberhalb der primären Spulenanordnung befindet. Nur dann ist eine hinreichend gute Kopplung zwischen den Spulenanordnungen gegeben.The width of the primary-side ferrite should be at least as large as the sum of twice the required lateral positioning tolerance and the width of the secondary-side ferrite. The lateral positioning tolerance is understood to be the maximum permitted lateral offset of the secondary-side coil arrangement relative to the center line of the primary coil arrangement. The vehicle may thus only be parked in such a way that the secondary coil arrangement is always located with its full width above the primary coil arrangement. Only then is there a sufficiently good coupling between the coil arrangements.
Unter einer stationär angeordneten primärseitigen Spulenanordnung wird eine Spulenanordnung verstanden, die entweder fest in oder an einer Fahrbahn oder einem Boden angeordnet bzw. verankert ist oder aber lediglich auf der Fahrbahn bzw. dem Boden, z. B. dem Boden einer Garage, aufgelegt ist.A stationarily arranged primary-side coil arrangement is understood to mean a coil arrangement which is either fixedly arranged or anchored in or on a roadway or a ground, or else only on the roadway or the ground, e.g. B. the floor of a garage, is launched.
Die Fahrrichtung ist im Sinne der Fahrtrichtung in X-Richtung definiert. Die primärseitige und die sekundärseitige Spulenanordnung sind in Z-Richtung zueinander beabstandet.The direction of travel is defined in the sense of the direction of travel in the X direction. The primary-side and the secondary-side coil arrangement are spaced apart in the Z-direction.
Zur Reduzierung des Luftspalts zwischen der primärseitigen und der sekundärseitigen Spulenanordnung kann eine von beiden in Richtung der anderen z. B. mittels einer Hebe- oder Absenkvorrichtung in Z-Richtung verstellt werden.To reduce the air gap between the primary-side and the secondary-side coil arrangement, one of the two in the direction of the other z. B. be adjusted by means of a lifting or lowering device in the Z direction.
Die Spulenanordnungen können entweder einen plattenförmigen oder im Querschnitt U- oder E-förmigen Ferritkern aufweisen. Sofern ein plattenförmiger Ferritkern verwendet wird, so ist die mindestens eine Wicklung parallel zur YZ-Ebene gewickelt. Hat der Spulenkern einen U- oder E-förmigen Querschnitt, so sind die Wicklungen vorzugsweise um einen oder mehrere Schenkel herum parallel zur XY-Ebene angeordnet.The coil arrangements can either have a plate-shaped or U-shaped or E-shaped ferrite core. If a plate-shaped ferrite core is used, the at least one winding is wound parallel to the YZ plane. If the coil core has a U-shaped or E-shaped cross section, the windings are preferably arranged around one or more legs parallel to the XY plane.
Vorteilhaft ist eine Steuereinrichtung vorgesehen, die die relative Position der primär- und sekundärseitigen Spulenanordnungen relativ zueinander in Fahrtrichtung ermittelt. Diese kann dem Fahrzeugführer oder dem Fahrzeug Informationen zu der momentanen Parkposition und notwendigen Fahrmanövern geben bzw. übermitteln. Die Steuereinrichtung kann hierzu akustische und/oder visuelle Signale erzeugen, die dem Fahrzeugführer zur optimalen Positionierung des Fahrzeuges relativ zur primären Spulenanordnung dienen.Advantageously, a control device is provided which determines the relative position of the primary and secondary coil arrangements relative to each other in the direction of travel. This can give or transmit information to the vehicle driver or the vehicle about the current parking position and necessary driving maneuvers. For this purpose, the control device can generate acoustic and / or visual signals which serve the driver for optimum positioning of the vehicle relative to the primary coil arrangement.
