Description
Die Erfindung betrifft eine Vorrichtung zur induktiven Übertragung elektrischer Energie zu beweglichen elektrischen Verbrauchern nach dem Oberbegriff des Anspruchs 1 sowie ein Verfahren zur induktiven Übertragung elektrischer Energie zu beweglichen elektrischen Verbrauchern nach dem Oberbegriff des Anspruchs 12.The invention relates to a device for inductive transmission of electrical energy to mobile electrical consumers according to the preamble of
Bei bekannten Vorrichtungen, insbesondere induktiven Ladestationen für Elektrofahrzeuge, wird üblicherweise jede Ladestation unabhängig von den anderen Ladestationen mit elektrischer Energie versorgt. Dabei weist eine Ladestation üblicherweise eine Primärspule auf, welche mit einer am Elektrofahrzeug angebrachten Sekundärspule induktiv koppeln kann. Die Versorgung der Primärspule erfolgt typischerweise durch einen Frequenzumrichter, welcher an ein Drehspannungs-Versorgungsnetz angeschlossen ist.In known devices, in particular inductive charging stations for electric vehicles, each charging station is usually supplied with electrical energy independently of the other charging stations. In this case, a charging station usually has a primary coil which can inductively couple with a secondary coil mounted on the electric vehicle. The supply of the primary coil is typically done by a frequency converter, which is connected to a three-phase supply network.
Dies weist den Nachteil auf, dass jeweils für jede Ladestation ein eigener Frequenzumrichter vorgesehen werden muss, was aufgrund der großen Kosten für einen Frequenzumrichter und der mit der Ansteuerung jedes Frequenzumrichters komplizierten Steuerung unerwünscht ist. Da die Ladestationen oft in die Fahrbahn oder den Boden eines Parkplatzes versenkt sind, muss zudem für jede Ladestation ein eigener Netzanschluss bereitgestellt werden. Dies ist baulich und isolationstechnisch aufwendig. Zudem erhöhen sich aufgrund der an den einzelnen Netzanschlüsse anliegenden Wechsel- bzw. Drehspannung die Leitungsverluste. Zudem muss im Fehlerfall die komplette Ladestation untersucht und ggf. demontiert werden, was zeitaufwendig und kostenintensiv ist.This has the disadvantage that in each case a separate frequency converter must be provided for each charging station, which is undesirable because of the large cost of a frequency converter and complicated with the control of each frequency control. Since the charging stations are often sunk into the roadway or the floor of a parking lot, also a separate power supply must be provided for each charging station. This is structurally and isolation technology consuming. In addition, the line losses increase as a result of the alternating or three-phase voltage applied to the individual mains connections. In addition, in the event of a fault, the complete charging station must be examined and possibly dismantled, which is time-consuming and expensive.
Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Vorrichtung und ein Verfahren zur induktiven Übertragung elektrischer Energie zu beweglichen elektrischen Verbrauchern bereitzustellen, welche die oben genannten Nachteile überwinden und eine baulich einfache, energiesparende und leicht zu betreibende Versorgung der beweglichen elektrischen Verbraucher zu ermöglichen.The invention is therefore based on the object, an apparatus and a method for inductive transmission of electrical energy to provide mobile electrical consumers, which overcome the disadvantages mentioned above and to enable a structurally simple, energy-saving and easy to operate supply of the moving electrical loads.
Diese Aufgabe löst die Erfindung durch eine Vorrichtung zur induktiven Übertragung elektrischer Energie zu beweglichen elektrischen Verbrauchern mit den Merkmalen des Anspruchs 1 sowie ein Verfahren zur induktiven Übertragung elektrischer Energie zu beweglichen elektrischen Verbrauchern mit den Merkmalen des Anspruchs 12. Vorteilhafte Weiterbildungen und Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved by the invention by a device for inductive transmission of electrical energy to mobile electrical consumers with the features of
Eine eingangs genannte Vorrichtung zur induktiven Übertragung elektrischer Energie zu beweglichen elektrischen Verbrauchern ist erfindungsgemäß dadurch gekennzeichnet, dass die Leistungsstellglieder der Ladestationen zur Versorgung mit Gleichstrom bzw. Gleichspannung eingangsseitig mit einem gemeinsamen Gleichstrom- bzw. Gleichspannungs-Zwischenkreis verbunden sind.An aforementioned device for the inductive transmission of electrical energy to mobile electrical loads is inventively characterized in that the power actuators of the charging stations are connected to the supply of DC or DC voltage input side to a common DC or DC link.
Hierdurch können wesentliche Teile der Vorrichtung schnell und leicht zugänglich und dennoch gegen den Zugriff Unberechtigter geschützt in einer gemeinsamen Station untergebracht werden, wobei aufgrund der in den Zuleitungen zu den einzelnen Ladestation anliegenden Gleichspannung die frequenzabhängigen Verluste vermieden werden können. Dies erweist sich insbesondere bei mehreren, nahe beieinander liegenden Ladestationen von Vorteil, beispielsweise in einem Busdepot, Parkhaus oder Parkplatz.As a result, essential parts of the device can be quickly and easily accessible and yet protected against access unauthorized persons are housed in a common station, the frequency-dependent losses can be avoided due to the applied in the leads to the individual charging station DC voltage. This proves to be particularly advantageous in the case of several charging stations located close to one another, for example in a bus depot, parking garage or parking lot.
Auch kann der Aufwand für die einzelnen Leistungsstellglieder deutlich verringert werden, da nicht jedes der Leistungsstellglieder einen eigenen Zwischenkreis mit aufwendiger Elektronik und teuere Zwischenkreisspeicherelementen benötigt. Auch kann der Verkabelungs- und Steuerungsaufwand hierdurch verringert werden. Zudem ermöglicht die Verwendung eines gemeinsamen Zwischenkreises die Rückspeisung elektrischer Energie von einem Fahrzeug in den Gleichspannungszwischenkreis.Also, the cost of the individual power actuators can be significantly reduced because not each of the power actuators requires its own DC link with elaborate electronics and expensive intermediate circuit memory elements. Also, the cabling and control effort can be reduced thereby. In addition, the use of a common intermediate circuit allows the return of electrical energy from a vehicle in the DC voltage intermediate circuit.
Vorteilhaft kann der Zwischenkreis mit einer Gleichspannungs- bzw. Gleichstromquelle verbunden sein, welche bevorzugt ein Gleichspannungs-Versorgungsnetz und/oder einen Gleichstromsteller umfasst. Weiter kann die Gleichspannungs- bzw. Gleichstromquelle einen Gleichrichter umfassen, insbesondere unter Verwendung elektronischer Leistungsschalter. Auch kann der Gleichrichter an ein Drehspannungs- und/oder Wechselspannungs-Versorgungsnetz angeschlossen sein.Advantageously, the intermediate circuit can be connected to a DC or DC power source, which preferably comprises a DC power supply network and / or a DC-DC converter. Furthermore, the DC or DC source may comprise a rectifier, in particular using electronic circuit breakers. The rectifier can also be connected to a three-phase voltage and / or alternating voltage supply network.
Weiter kann vorteilhaft zwischen den Gleichrichter und das Versorgungsnetz ein Netzrückwirkungsfilter bzw. Leistungsfaktorkorrekturfilter geschaltet sein, welche vorteilhaft passiv oder aktiv und/oder rückspeisefähig sein kann. Ggf. kann auch ein oberschwingungsoptimierter Gleichrichter verwendet werden.Furthermore, a network feedback filter or power factor correction filter can advantageously be connected between the rectifier and the supply network, which can advantageously be passive or active and / or regenerative. Possibly. It is also possible to use a harmonic-optimized rectifier.
In einer vorteilhaften Ausgestaltung kann mit dem Zwischenkreis ein elektrischer Energiespeicher verbunden sein, der beispielsweise in Zeiten, in denen der allgemeine Strombedarf geringer ist, aufgeladen wird, so dass die Netzbelastung verringert und vergleichmäßigt werden kann. Die Ladestationen können dann zumindest für eine gewisse Zeit unabhängig vom Versorgungsnetz betrieben werden.In an advantageous embodiment may be connected to the intermediate circuit, an electrical energy storage, which is charged, for example, in times when the general power consumption is lower, so that the network load can be reduced and made uniform. The charging stations can then be operated at least for a certain time independently of the supply network.
Vorteilhaft kann der Energiespeicher mindestens einen Akkumulator, einen Kondensator, insbesondere einen sog. Supercap, eine Induktivität und/oder ein Speichernetzwerk umfasst. Bevorzugt kann mindestens eines der Leistungsstellglieder zum Rückspeisen von elektrischer Energie in den Zwischenkreis ausgebildet sein, beispielsweise als Vierquadrantensteller. Dabei können die Leistungsstellglieder und/oder die Gleichspannungs- bzw. Gleichstromquelle und/oder der Energiespeicher mit einer gemeinsamen Steuerung der Vorrichtung verbunden sein, wodurch sich der Steuerungsaufwand vereinfachen lässt.Advantageously, the energy storage at least one accumulator, a capacitor, in particular a so-called. Supercap, an inductance and / or a storage network comprises. Preferably, at least one of the power actuators can be designed to feed back electrical energy into the intermediate circuit, for example as a four-quadrant controller. In this case, the power actuators and / or the DC voltage or DC power source and / or the energy storage can be connected to a common control of the device, whereby the control effort can be simplified.
Ein eingangs genanntes Verfahren ist erfindungsgemäß dadurch gekennzeichnet, dass die Leistungsstellglieder zur Versorgung mit Gleichstrom bzw. Gleichspannung aus einem gemeinsamen Gleichstrom- bzw. Gleichspannungs-Zwischenkreis gespeist werden. Bevorzugt kann dabei die Vorrichtung wie oben und nachstehend angegeben ausgebildet sein.An aforementioned method is inventively characterized in that the power actuators are fed to supply DC or DC voltage from a common DC or DC intermediate circuit. In this case, the device may preferably be designed as indicated above and below.
Bevorzugt kann von einem Verbraucher rückgespeiste elektrische Energie von dem Leistungsstellglied der zugeordneten Ladestation in den Zwischenkreis zurückgespeist werden. Hierdurch kann diese elektrische Energie „wiederververwendet” werden, es ergibt sich im Betrieb eine Energieeinsparung. Bevorzugt kann dabei die rückgespeiste Energie in einem mit dem Zwischenkreis verbundenen elektrischen Energiespeicher gespeichert und/oder einem einer anderen Ladestation zugeordneten Verbraucher zugeführt werden.Preferably, electrical energy fed back by a consumer can be fed back from the power actuator of the associated charging station into the DC link. As a result, this electrical energy can be "reused", it results in the operation of energy savings. In this case, the energy fed back can preferably be stored in an electrical energy store connected to the DC link and / or supplied to a load assigned to another charging station.
In einer betrieblich günstigen Ausführung kann auf Anforderung eines elektrischen Verbrauchers das Leistungsstellglied der dem Verbraucher zugeordneten Ladestation die angeforderte Leistung individuell für diesen Verbraucher bereitstellen. Hierdurch kann eine energetisch optimale Einstellung erfolgen, so dass jedem Verbraucher die benötigte Energie zugeführt werden kann, ohne Energie zu verschwenden.In a low-cost embodiment, the power actuator of the charging station associated with the consumer can provide the requested power individually for this consumer at the request of an electrical consumer. As a result, an energetically optimal setting can be made so that each consumer can be supplied with the required energy without wasting energy.
Weiter kann mindestens eine den Gleichstrom- bzw. Gleichspannungs-Zwischenkreis speisende Gleichspannungs- bzw. Gleichstromquelle vorgesehen sein, die auf Basis von einzelnen Leistungsanforderungen der an den Ladestationen stehenden elektrischen Verbrauchern und/oder der zugeordneten Leistungsstellglieder die insgesamt angeforderte Leistung im Gleichstrom- bzw. Gleichspannungs-Zwischenkreis bereitstellt. Hierdurch kann die im Zwischenkreis benötigte Energie optimal eingestellt werden, so dass einerseits nicht zuwenig vorhanden ist, zum anderen aber nicht zuviel Energie bereitgestellt wird, welche eigentlich nicht benötigt wird.Furthermore, at least one DC or DC source supplying the DC or DC intermediate circuit can be provided which, on the basis of individual power requirements of the electrical consumers standing at the charging stations and / or the associated power actuators, supplies the total requested DC or DC voltage -Intermediate circuit. As a result, the energy required in the intermediate circuit can be set optimally, so that on the one hand not too little is available, on the other hand, not too much energy is provided, which is actually not needed.
