Abstract
Description
Die vorliegende Erfindung betrifft eine Steuerungsvorrichtung für einen Zwischenkreis eines Energieversorgungssystems eines Fahrzeugs, das eine Brennstoffzelle und eine Batterie aufweist, wobei die Steuerungsvorrichtung eine Wandlereinrichtung besitzt, die zwischen die Batterie und den Zwischenkreis geschaltet ist.The The present invention relates to a control device for an intermediate circuit of a power supply system of a vehicle, comprising a fuel cell and a battery, wherein the control device has a transducer means which between the battery and the DC link is connected.
In einem elektrischen Antriebsstrang eines Fahrzeugs können verschiedene elektrische Quellen für die Versorgung eines Elektromotors vorgesehen sein. Beispielsweise werden eine Batterie und ein Brennstoffzellensystem (Brennstoffzellen-Stack) als Energiequellen eingesetzt.In an electric drive train of a vehicle can various electrical sources for the supply of a Be provided electric motor. For example, a battery and a fuel cell system (fuel cell stack) as energy sources used.

Die Aufgabe der vorliegenden Erfindung besteht darin, die Last in einem Brennstoffzellensystem besser zu verteilen.The Object of the present invention is to load in a To distribute fuel cell system better.
Erfindungsgemäß ist
diese Aufgabe gelöst durch eine Steuerungsvorrichtung nach
Anspruch 1 und ein Verfahren nach Anspruch 5. Weiterbildungen der
Erfindung ergeben sich aus den Unteransprüchen. Erfindungsgemäß ist
demnach vorgesehen eine Steuerungsvorrichtung für einen
Zwischenkreis eines Energieversorgungssystems eines Fahrzeugs, das
eine Brennstoffzelle und eine Batterie aufweist, mit einer ersten
Wandlereinrichtung, die zwischen die Batterie und den Zwischenkreis
geschaltet ist, wobei eine zweite Wandlereinrichtung, die zwischen
die Brennstoffzelle und den Zwischenkreis geschaltet ist, einen
periodischen Lastwechsel größtenteils auf die Brennstoffzelle
abbildet.According to the invention
this problem is solved by a control device according to
In vorteilhafter Weise ist es so möglich, einen periodischen Lastanteil gezielt einer Brennstoffzelle zuzuteilen, die eine nicht zu vernachlässigende Doppelschichtkapazität besitzt. Dadurch kann vermieden werden, dass periodische Leistungsanteile („Stromrippel”) vom Zwischenkreis auf die Batterieseite gespiegelt werden. Durch die periodischen Leistungsanteile würde nämlich eine unerwünschte Belastung der Batterie entstehen, welche zu einer zusätzlichen Erwärmung der Batterie führt. Die zusätzliche Erwärmung bedeutet einen erheblichen Mehraufwand bei der Auslegung der Batterie und deren Kühlsystem. Das Energiewandlersystem (Brennstoffzelle) verfügt hingegen ohnehin über ein gut ausgebildetes Kühlsystem.In Advantageously, it is possible to have a periodic Allocate load fraction targeted to a fuel cell, which is not one has negligible double-layer capacity. This can be avoided that periodic performance shares ("Current ripple") from the DC link to the battery side be mirrored. By the periodic performance shares would namely an undesirable burden on the battery resulting in additional heating the battery leads. The additional warming means a considerable extra effort in the design of the battery and their cooling system. The energy converter system (fuel cell) however, has a well-trained anyway Cooling system.
In vorteilhafter Weise lassen sich so hochdynamische elektrische Eigenschaften des Zwischenkreises bei gleichzeitig moderater Auslegung des Brennstoffzellensystems erzielen. Gleichzeitig lässt sich die hochdynamische Spannungsregelung im Zwischenkreis beibehalten. Außerdem kann die Batteriekühlung vereinfacht werden und die Doppelschichtkapazität der Brennstoffzelle wird trotz Spannungswandler („Boost Converter”) genutzt.Advantageously, it is possible to achieve such highly dynamic electrical properties of the intermediate circuit while at the same time providing a moderate design of the fuel cell system. At the same time lets maintain the highly dynamic voltage regulation in the DC link. In addition, the battery cooling can be simplified and the double-layer capacity of the fuel cell is used in spite of voltage converter ("Boost Converter").
Vorzugsweise bildet die erste Wandlereinrichtung der oben genannten erfindungsgemäßen Steuervorrichtung einen transienten Lastwechsel auf die Batterie ab. Hierzu kann die erste Wandlereinrichtung eine Bandsperre aufweisen, so dass vorgegebene Frequenzen nicht auf die Batterie abgebildet werden. Außerdem kann mit der zweiten Wandlereinrichtung eine Wechselstrominformation von dem Zwischenkreis zur Regelung der Zwischenkreisspannung direkt oder indirekt abgreifbar sein.Preferably forms the first converter device of the above-mentioned control device according to the invention a transient load change on the battery. For this purpose, the first converter means comprise a band-stop filter, so that predetermined Frequencies can not be mapped to the battery. Furthermore can with the second converter means an AC information from the DC link to control the DC link voltage directly or be indirectly accessible.
Die vorliegende Erfindung wird anhand der beigefügten Zeichnungen näher erläutert, in denen zeigen:The The present invention will become apparent from the accompanying drawings explained in more detail, in which show:
Die nachfolgend näher geschilderten Ausführungsbeispiele stellen bevorzugte Ausführungsformen der vorliegenden Erfindung dar.The Below described embodiments represent preferred embodiments of the present invention represents.
Das
folgende Beispiel gemäß
Sinnvollerweise
ist dies die Energiequelle, welche die höchste Dynamik
aufweist, hier die Batterie
Für die periodisch wechselnden Stromschwankungen wäre eine entsprechend groß dimensionierte Zwischenkreiskapazität von Vorteil. Diese ist jedoch aufgrund von Baugröße und Kosten möglichst zu vermeiden bzw. klein zu halten. Ein Brennstoffzellen-Stack besitzt allerdings eine (sehr) große Kapazität (Doppelschichtkapazität), welche durch den Einsatz des Wandlers W2 nicht mehr in vollem Umfang als Zwischenkreiskapazität zur Verfügung steht.For the periodically changing current fluctuations would be one correspondingly large DC link capacitance advantageous. However, this is due to size and to avoid costs or keep them as small as possible. However, a fuel cell stack has a (very) large capacity (Double layer capacity), which by the use of the Converter W2 no longer in full as DC link capacity is available.
Insgesamt wird jedoch angestrebt,
- 1. periodische Lastwechsel (Wechselanteil des Laststroms) auf die Brennstoffzelle abzubilden und
- 2. transiente Lastwechsel auf die Batterieseite abzubilden.
- 1. Map periodic load changes (alternating part of the load current) to the fuel cell and
- 2. depict transient load changes on the battery side.
Um
periodische Lastwechsel von der Batterie fernzuhalten, jedoch die
transienten Lastwechsel mithilfe der Batterie zu realisieren, werden
in einem Ausführungsbeispiel gemäß
Auf
der Brennstoffzellenseite ist ein Wandler W2 vorgesehen, was bereits
im Zusammenhang mit
Wird
das Filter F1 – wie oben angedeutet – als Bandsperre
ausgelegt, so werden sowohl der Gleichanteil („niedrige
Frequenzen”) als auch transiente Lastanteile („hohe
Frequenzen”) ausgeregelt und somit von der Batterie getragen.
Damit ein periodischer Lastwechsel (welcher also nicht von der Batterie
