Description
Die Erfindung betrifft ein Ladesystem.The invention relates to a charging system.
Es ist allgemein bekannt, dass über eine induktive Kopplung Energie übertragbar ist von einer Primärspule an eine Sekundärspule.It is well known that energy can be transferred via an inductive coupling from a primary coil to a secondary coil.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Ladesystem weiterzubilden, wobei eine möglichst starke Kopplung erreichbar ist.The invention is therefore based on the object to develop a charging system, with the highest possible coupling can be achieved.
Erfindungsgemäß wird die Aufgabe bei dem Ladesystem nach den in Anspruch 1 angegebenen Merkmalen gelöst.According to the invention the object is achieved in the charging system according to the features specified in claim 1.
Wichtige Merkmale der Erfindung bei dem Ladesystem sind, dass das Ladesystem eine am Boden stationär angeordnete Einfädelhilfe und zumindest ein auf dem Boden verfahrbares Fahrzeug umfasst,
wobei an der Unterseite des Fahrzeugs eine Sekundärspule angeordnet ist, mit der ein Energiespeicher des Fahrzeugs beladbar ist, insbesondere mittels eines Ladestromreglers und/oder Ladespannungsreglers des Fahrzeugs,
wobei an einer Radachse des Fahrzeugs zwei Räder angeordnet sind und die die Sekundärspule axial außermittig, insbesondere aber axial zwischen den beiden Rädern, angeordnet ist,
wobei mittels der Einfädelhilfe eines der zwei Räder des Fahrzeugs, insbesondere das weniger von der Sekundärspule beabstandete Rad der zwei Räder, zu einer optimalen Position hin einfädelbar ist.Important features of the invention in the charging system are that the charging system comprises a stationary at the bottom arranged Einfädelhilfe and at least one movable on the ground vehicle
wherein a secondary coil is arranged on the underside of the vehicle, with which an energy store of the vehicle can be loaded, in particular by means of a charging current regulator and / or charging voltage regulator of the vehicle,
wherein two wheels are arranged on a wheel axle of the vehicle and the secondary coil is arranged axially off-center, but in particular axially between the two wheels,
wherein by means of the Einfädelhilfe one of the two wheels of the vehicle, in particular the less spaced from the secondary coil wheel of the two wheels, can be threaded to an optimal position.
Von Vorteil ist dabei, dass mittels des Einfädeln eines der Räder des Fahrzeugs zur optimalen Position hin eine starke induktive Kopplung erreichbar ist, da der Abstand zwischen der Einfädelhilfe und der Primärspule entsprechend dem Abstand des eingefädelten Rades und der Sekundärspule ausbildbar ist. Somit ist automatisch gesichert, dass die Sekundärspule über der Primärspule liegt, wenn das Fahrzeug die optimale Position erreicht.The advantage here is that by means of the threading of the wheels of the vehicle to the optimum position towards a strong inductive coupling can be achieved, since the distance between the threading and the primary coil according to the distance of the threaded wheel and the secondary coil can be formed. Thus, it is automatically ensured that the secondary coil is above the primary coil when the vehicle reaches the optimum position.
Bei einer vorteilhaften Ausgestaltung ist das Fahrzeug zumindest dreispurig ausgeführt, wobei ein drittes Rad am Fahrzeug axial mittig zu den beiden Rädern angeordnet ist, insbesondere aber in Fahrtrichtung beabstandet von der Radachse,
wobei die Sekundärspule außermittig angeordnet ist, insbesondere also axial zwischen einem der zwei Räder und dem dritten Rad. Von Vorteil ist dabei, dass durch die außermittige Lage der Primärspule ein Überfahren der Primärspule durch das dritte Rad vermieden ist. Außerdem ist das dritte Rad auch weit entfernt von der Einfädelhilfe. Somit ist auch hier kein Überfahren ausführbar.In an advantageous embodiment, the vehicle is designed at least three lanes, wherein a third wheel is arranged axially centrally of the vehicle to the two wheels, but in particular in the direction of travel spaced from the wheel axle,
wherein the secondary coil is arranged eccentrically, ie in particular axially between one of the two wheels and the third wheel. It is advantageous that the overrunning of the primary coil by the third wheel is avoided by the off-center position of the primary coil. In addition, the third wheel is also far from the Einfädelhilfe. Thus, no overrun is executable here.
Bei einer vorteilhaften Ausgestaltung tritt in der optimalen Position die stärkste induktive Kopplung der Sekundärspule zur Primärspule auf, insbesondere im Vergleich zu allen sonstigen vom Fahrzeug am Boden erreichbaren Positionen. Von Vorteil ist dabei, dass ein hoher Wirkungsgrad bei der Übertragung erreichbar ist.In an advantageous embodiment, the strongest inductive coupling of the secondary coil to the primary coil occurs in the optimum position, in particular in comparison to all other achievable by the vehicle on the ground positions. The advantage here is that a high efficiency in transmission is achievable.
Bei einer vorteilhaften Ausgestaltung weist die Einfädelhilfe eine Vertiefung auf, deren axiale Breite in zur axialen Richtung senkrechter Richtung sich zur optimalen Position hin verringert und deren Höhe ein lokales Minimum im Bereich der optimalen Position, insbesondere ein lokales Minimum an der optimalen Position, aufweist,
insbesondere so dass das eingefädelte Rad bei Einfahren in die Vertiefung der Einfädelhilfe zur optimalen Position hin positioniert wird. Von Vorteil ist dabei, dass ein automatisches Positionieren ermöglicht ist, indem der Antrieb oder Bremse des Fahrzeugs im Bereich der optimalen Position abgekoppelt wird vom entsprechenden Rad des Fahrzeugs und somit ein selbsttätiges Erreichen des Tiefpunktes, also der optimalen Position ermöglicht wird. Insbesondere ist dies in einfacher Weise ermöglicht, indem die optimale Position als lokales Minimum ausgeführt ist.In an advantageous embodiment, the threading aid has a depression whose axial width decreases in the direction perpendicular to the axial direction to the optimum position and whose height has a local minimum in the region of the optimum position, in particular a local minimum at the optimum position.
in particular so that the threaded wheel is positioned to the optimum position when entering the recess of the threading. The advantage here is that an automatic positioning is made possible by the drive or brake of the vehicle is decoupled in the region of the optimal position of the corresponding wheel of the vehicle and thus an automatic reaching the low point, so the optimum position is enabled. In particular, this is made possible in a simple manner in that the optimal position is implemented as a local minimum.
Bei einer vorteilhaften Ausgestaltung ist ein Sensor, insbesondere ein Näherungssensor, insbesondere ein induktiver Näherungssensor, zur Detektion des Rades beim Eintreffen in der optimalen Position an der Einfädelhilfe angeordnet. Von Vorteil ist dabei, dass die Einspeisung des Stromes in die Primärspule erst dann begonnen wird, wenn das Fahrzeug auch eingetroffen ist und genügend stark induktiv ankoppelbar ist.In an advantageous embodiment, a sensor, in particular a proximity sensor, in particular an inductive proximity sensor, is arranged for detecting the wheel when it arrives in the optimum position on the threading aid. The advantage here is that the feed of the current into the primary coil is only started when the vehicle has arrived and sufficiently strong inductively coupled.
Bei einer vorteilhaften Ausgestaltung ist ein Einspeisegerät samt Primärspule mit der Einfädelhilfe als bauliche Einheit ausgebildet,
wobei diese Einheit auf dem Boden angeordnet ist. Von Vorteil ist dabei, dass eine einfache Montage ausführbar ist und der Abstand zwischen Einfädelhilfe und Primärspule in einfacher Weise fest legbar ist.In an advantageous embodiment, a feed device together with the primary coil with the threading aid is designed as a structural unit,
this unit is placed on the floor. The advantage here is that a simple installation is executable and the distance between Einfädelhilfe and primary coil in a simple manner is laid out.
Bei einer vorteilhaften Ausgestaltung ist mittels des Einspeisegeräts ein mittelfrequenter Strom in die Primärspule einprägbar, insbesondere mit einer Frequenz zwischen 10 und 1000 kHz. Von Vorteil ist dabei, dass ein hoher Wirkungsgrad erreichbar ist.In an advantageous embodiment, a medium-frequency current can be imprinted in the primary coil by means of the supply device, in particular with a frequency between 10 and 1000 kHz. The advantage here is that a high efficiency can be achieved.
Bei einer vorteilhaften Ausgestaltung ist der Sekundärspule eine Kapazität derart in Reihe oder parallel zugeschaltet, dass die zugehörige Resonanzfrequenz des so gebildeten Schwingkreises im Wesentlichen der Frequenz des mittelfrequenten Stroms entspricht. Von Vorteil ist dabei, dass auch bei Abweichung von der optimalen Position schon ein hoher Wirkungsgrad erreichbar ist, der von der Größe der Abweichung nur schwach abhängt, insbesondere im Vergleich zu einer nicht resonanten Übertragung.In an advantageous embodiment of the secondary coil is a capacity connected in series or in parallel, that the associated resonant frequency of the resonant circuit thus formed substantially corresponds to the frequency of the medium-frequency current. The advantage here is that even with deviation from the optimal position already a high efficiency can be achieved, the size of the the deviation depends only weakly, especially in comparison to a non-resonant transmission.
Bei einer vorteilhaften Ausgestaltung wird der induktiv in der Sekundärspule erzeugte Strom einem Gleichrichter zugeführt, der einen Laderegler zur Aufladung eines Energiespeichers des Fahrzeugs speist. Von Vorteil ist dabei, dass der Antrieb des Fahrzeugs aus dem Energiespeicher versorgbar ist.In an advantageous embodiment of the inductively generated in the secondary coil current is supplied to a rectifier, which feeds a charge controller for charging an energy storage of the vehicle. The advantage here is that the drive of the vehicle from the energy storage is supplied.
Bei einer vorteilhaften Ausgestaltung ist bei Erreichen der Optimalen Position die Sekundärspule in Gravitationsrichtung über der Primärspule angeordnet. Von Vorteil ist dabei, dass eine hohe Effektivität und ein hoher Wirkungsgrad erreichbar sind.In an advantageous embodiment, when the optimum position is reached, the secondary coil is arranged in the gravitational direction over the primary coil. The advantage here is that high efficiency and high efficiency can be achieved.
Bei einer vorteilhaften Ausgestaltung ist am Einspeisegerät ein Anzeigemittel angeordnet, mit dem der Status des Ladegeräts oder des Energiespeichers des Fahrzeugs anzeigbar ist. Von Vorteil ist dabei, dass der fahrzeugseitige Status primärseitig, also am stationären Gerät, anzeigbar ist.In an advantageous embodiment, a display means is arranged on the supply device, with which the status of the charger or the energy storage of the vehicle can be displayed. The advantage here is that the vehicle-side status can be displayed on the primary side, ie on the stationary device.
Bei einer vorteilhaften Ausgestaltung ist zwischen Einspeisegerät und einer fahrzeugseitigen Elektronik ein Kommunikationskanal ausgebildet, insbesondere mittels auf die Primärspule und/oder Sekundärspule aufmodulierter höher frequenter Stromanteile. Von Vorteil ist dabei, dass Daten übertragbar sind, insbesondere der Status des Ladegeräts oder des Energiespeichers.In an advantageous embodiment, a communication channel is formed between the supply device and a vehicle-side electronics, in particular by means of modulated on the primary coil and / or secondary coil higher frequency current components.

Hierbei weist das Fahrzeug an seiner Unterseite eine Sekundärspule
Beim Einfädeln wird einerseits die Position des Berührpunktes zwischen einem der Räder und dem Boden oder der Einfädelhilfe beeinflusst und andererseits auch die Ausrichtung des Fahrzeugs, insbesondere der Achse des Rads.During threading, the position of the contact point between one of the wheels and the ground or the threading aid is influenced on the one hand, and on the other hand also the orientation of the vehicle, in particular the axis of the wheel.
Das Einfädeln ist hierbei verschiedenartig ausführbar. Vorzugsweise wird eine zur optimalen Position hin sich verjüngende Nut vorgesehen, so dass mittels der Einfädelhilfe das Rad beim Einfahren in die Nut entlang der Nutrichtung ausgerichtet wird und das Rad die optimale Position erreicht. Vorzugsweise ist diese optimale Position ein lokales Höhenminimum, also ein Tiefpunkt, insbesondere entlang der Nutrichtung. Somit rollt das Fahrzeug auch selbsttätig zur optimalen Position. Die Verengung ist derart ausgeführt, dass das Rad axial beidseitig nur wenig oder kein Spiel zu den Nutwänden hin aufweist.The threading here is variously executable. Preferably, a groove tapering towards the optimum position is provided, so that the wheel is aligned along the groove direction when entering the groove by means of the threading aid and the wheel reaches the optimum position. Preferably, this optimum position is a local altitude minimum, ie a low point, in particular along the groove direction. Thus, the vehicle rolls automatically to the optimum position. The constriction is carried out such that the wheel has axially on both sides little or no play to the groove walls out.
Die Einfädelhilfe ist als Formteil ausführbar, wobei die Nut eingeformt ist. Das Formteil ist dabei auf dem Boden, also der Verfahrfläche für das Fahrzeug positionierbar und/oder befestig bar.The Einfädelhilfe is executable as a molded part, wherein the groove is formed. The molding is positioned on the floor, so the traversing surface for the vehicle and / or fastened bar.
