Abstract
Description
Die Erfindung betrifft eine Schaltungsanordnung zum Koppeln einer HV-Batterie mit einem Fahrzeugnetz nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a circuit arrangement for coupling a HV battery with a vehicle network according to the preamble of patent claim 1.
Die
Im Allgemeinen dienen Schütze in HV-Batterien zwei Zielen, zum einen dienen sie der galvanischen Trennung der Zellen von der Außenwelt und zum anderen der Unterbrechung unerwünschter Ströme. Somit müssen Schütze sehr robust ausgelegt sein, was den Nachteil hat, dass sie demzufolge in ihrer Dimensionierung relativ groß sind.In general, contactors in HV batteries serve two purposes; on the one hand, they serve to galvanically separate the cells from the outside world and, on the other hand, to interrupt unwanted currents. Thus, shooters must be designed very robust, which has the disadvantage that they are therefore relatively large in their dimensions.
Die Aufgabe der vorliegenden Erfindung ist es daher eine Schaltungsanordnung zum Koppeln einer HV-Batterie mit einem Fahrzeugnetz bereitzustellen, die kompakter ausgestaltet werden kann.The object of the present invention is therefore to provide a circuit arrangement for coupling a HV battery to a vehicle network, which can be made more compact.
Diese Aufgabe wird durch eine Schaltungsanordnung mit den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved by a circuit arrangement having the features of patent claim 1.
Die erfindungsgemäße Schaltungsanordnung zum Koppeln einer HV-Batterie eines Fahrzeugs mit einem Fahrzeugnetz umfasst einen ersten Schütz, zu welchem ein leistungselektronischer Schalter in Reihe geschaltet ist. Der leistungselektronische Schalter ist dabei zur Stromunterbrechung zwischen der HV-Batterie und dem Fahrzeugnetz ausgelegt. Der leistungselektronische Schalter kann dabei beispielsweise als IGBT, GTO, FET oder MOSFET ausgebildet sein.The inventive circuit arrangement for coupling a HV battery of a vehicle with a vehicle network comprises a first contactor, to which a power electronic switch is connected in series. The power electronic switch is designed for power interruption between the HV battery and the vehicle network. The power electronic switch can be designed, for example, as IGBT, GTO, FET or MOSFET.
Die Stromunterbrechung erfordert eine sehr viel robustere Konstruktion als es die galvanische Trennung erfordern würde. Bei einem Einsatz eines leistungselektronischen Schalters, wie beispielsweise eines Halbleiterelements, z. B. ein FET oder MOSFET, in Serie zum mechanischen Schütz (hier „erster Schütz”) kann der leistungselektronischen Schalter die Unterbrechung der unerwünschten Ströme sehr effizient übernehmen. Dies hat den besonders großen Vorteil, dass der erste Schütz somit deutlich kleiner dimensioniert werden kann, da er nur noch lastfrei schalten muss und ausschließlich der galvanischen Trennung dient. Der leistungselektronischen Schalter zusammen mit dem ersten Schütz ist darüber hinaus ebenfalls deutlich kleiner als die im Stand der Technik üblicherweise verwendeten Hauptschütze. So wird durch die Kombination eines ersten Schützes und eines leistungselektronischen Schalters eine wesentlich kompaktere Anordnung ermöglicht.The power interruption requires a much more robust design than galvanic isolation would require. When using a power electronic switch, such as a semiconductor element, for. As a FET or MOSFET, in series with the mechanical contactor (here "first contactor"), the power electronic switch can take the interruption of unwanted currents very efficient. This has the particularly great advantage that the first contactor can thus be dimensioned significantly smaller, since it only has to switch load-free and is used exclusively for galvanic isolation. In addition, the power electronic switch together with the first contactor is also significantly smaller than the main contactors commonly used in the art. Thus, a much more compact arrangement is made possible by the combination of a first contactor and a power electronic switch.
Bei einer bevorzugten Ausgestaltung der Erfindung ist die HV-Batterie über den ersten Schütz und einen zweiten Schütz mit dem Fahrzeugnetz koppelbar. So steht eine äußerst platzsparende Möglichkeit bereit eine Schaltungsanordnung zum Koppeln einer HV-Batterie mit einem Fahrzeugnetz in ein Fahrzeug zu integrieren.In a preferred embodiment of the invention, the HV battery via the first contactor and a second contactor with the vehicle network can be coupled. Thus, an extremely space-saving option is available to integrate a circuit arrangement for coupling a HV battery with a vehicle network in a vehicle.
Bei einer vorteilhaften Ausgestaltung der Erfindung ist der leistungselektronische Schalter, wie beispielsweise ein FET oder MOSFET dazu ausgelegt, einen Einschaltstrom zu begrenzen. Da das Fahrzeugnetz üblicherweise eine Pufferkapazität umfasst, entstehen beim Koppeln der HV-Batterie mit dem Fahrzeugnetz hohe Einschaltströme, die exponentiell in der Zeit abfallen, bis die Pufferkapazität geladen ist. Durch das Vorsehen eines Feldeffekttransistors oder MOSFET in Serie mit dem ersten Schütz können so Einschaltströme begrenzt werden, die so eine erlaubte Stromstärke nicht überschreiten. Darüber hinaus kann vorteilhafterweise durch den Feldeffekttransistor oder MOSFET eine zeitlich konstante Stromstärke des Ladestroms bereitgestellt werden, wodurch sich die Ladezeit des der Pufferkapazität verkürzt. Somit kann der Feldeffekttransistor oder MOSFET nicht nur zur Unterbrechung unerwünschter Ströme genutzt werden, sondern gleichzeitig auch als Einschaltbegrenzer, welcher auch ein lastfreies Schalten der Schütze erlaubt und erst nach erfolgreichem Kontaktieren den Stromkreis schließt.In an advantageous embodiment of the invention, the power electronic switch, such as a FET or MOSFET is designed to limit an inrush current. Since the vehicle network usually comprises a buffer capacity, when the HV battery is connected to the vehicle network, high inrush currents occur, which decrease exponentially in time until the buffer capacity is charged. By providing a field effect transistor or MOSFET in series with the first contactor so inrush currents can be limited, which do not exceed such a permitted current. In addition, a temporally constant current intensity of the charging current can advantageously be provided by the field effect transistor or MOSFET, whereby the charging time of the buffer capacity is shortened. Thus, the field effect transistor or MOSFET can be used not only to interrupt unwanted currents, but at the same time as a Einschaltbegrenzer, which also allows a load-free switching of the contactors and only after successful contact closes the circuit.
Bei einer weiteren vorteilhaften Ausgestaltung der Erfindung ist die Schaltungsanordnung als Modul ausgebildet. Besonders vorteilhaft ist dabei die Integration des geschrumpften ersten Schützes mit dem leistungselektronischen Schalter in ein gemeinsames Gehäuse. Gleichzeitig können auch die nach außen geführten Steuerleitungen minimiert werden.In a further advantageous embodiment of the invention, the circuit arrangement is designed as a module. Particularly advantageous is the integration of the shrunken first contactor with the power electronic switch in a common housing. At the same time, the externally routed control lines can be minimized.
Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus den Ansprüchen, der nachfolgenden Beschreibung bevorzugter Ausführungsformen sowie anhand der Zeichnung.Further advantages, features and details of the invention will become apparent from the claims, the following description of preferred embodiments and from the drawing.
Dabei zeigt
Aus der Verwendung eines Feldeffekttransistors
Insgesamt wird so eine Schaltungsanordnung zum Koppeln einer HV-Batterie eines Fahrzeugs mit einem Fahrzeugnetz bereitgestellt, die eine äußerst kompakte Anordnung ermöglicht durch die Verwendung eines in Serie zu einem Schütz geschalteten leistungselektronischen Schalters, der die Aufgabe der Unterbrechung unerwünschter Ströme übernimmt. Gleichzeitig ermöglicht diese Anordnung auch die Verwendung eines Feldeffekttransistors oder MOSFETs zur Einschalt- und Kurzschlussstrombegrenzung.Overall, such a circuit arrangement is provided for coupling a HV battery of a vehicle with a vehicle network, which allows an extremely compact arrangement by using a series-connected to a contactor power electronic switch, which takes on the task of interrupting unwanted currents. At the same time, this arrangement also allows the use of a field effect transistor or MOSFETs for turn-on and short-circuit current limiting.
