Description
Die Erfindung betrifft einen zentralen Traktionsnetzverteiler eines Traktionsnetzes eines Kraftfahrzeugs sowie ein Traktionsnetz mit einem solchen zentralen Traktionsnetzverteilers.The invention relates to a central traction network distributor of a traction network of a motor vehicle and a traction network with such a central traction network distributor.
In der
Der Erfindung liegt das technische Problem zugrunde, einen zentralen Traktionsnetzverteiler zu verbessern sowie ein verbessertes Traktionsnetz zu schaffen, das flexibler anpassbar und einsetzbar ist.The invention is based on the technical problem of improving a central traction network distributor and of creating an improved traction network which can be adapted and used more flexibly.
Die Lösung des technischen Problems ergibt sich durch einen zentralen Traktionsnetzverteiler mit den Merkmalen des Anspruchs 1 sowie ein Traktionsnetz mit den Merkmalen des Anspruchs 10. Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.The technical problem is solved by a central traction network distributor with the features of
Hierzu weist der zentrale Traktionsnetzverteiler eines Traktionsnetzes eines Kraftfahrzeugs mindestens ein Steuergerät auf, wobei das Steuergerät derart ausgebildet ist, dass mindestens eine Funktion des Traktionsnetzes durch das Steuergerät gesteuert wird. Durch die zentrale Steuerung mindestens einer Funktion ist das Traktionsnetz vereinfachter an verschiedene Hardware-Konfigurationen anpassbar.For this purpose, the central traction network distributor of a traction network of a motor vehicle has at least one control unit, the control unit being designed such that at least one function of the traction network is controlled by the control unit. The central control of at least one function makes the traction network easier to adapt to different hardware configurations.
In einer Ausführungsform ist in dem zentralen Traktionsnetzverteiler eine Einrichtung zur aktiven Entladung angeordnet. Eine solche Einrichtung zur aktiven Entladung dient insbesondere dazu, in bestimmten Fällen, wie beispielsweise Crash oder Reparatur, gezielt kapazitive Spannungen nach Abschaltung der Hochvoltbatterie abzubauen. Hierzu besteht eine solche Einrichtung beispielsweise aus einem Schalter (z.B. einem Relais) und einem ohmschen Widerstand, die in Reihe zwischen einem positiven Hochvolt-Potential und einem negativen Hochvolt-Potential geschaltet sind. Durch die Zuschaltung des ohmschen Widerstandes werden dann die Kapazitäten gezielt entladen, wobei die Entladung umso schneller geht, je kleiner der ohmsche Widerstand ist. Diese aktive Entladung kann nun zentral erfolgen, wobei dann je nach Hardware-Konfiguration der Widerstandswert gewählt wird. Somit kann auf mehrere dezentral verteilte Einrichtungen zur aktiven Entladung verzichtet werden bzw. diese kleiner dimensioniert werden.In one embodiment, a device for active discharge is arranged in the central traction network distributor. Such a device for active discharge is used, in particular, to specifically reduce capacitive voltages in certain cases, such as a crash or repair, after the high-voltage battery has been switched off. For this purpose, such a device consists, for example, of a switch (e.g. a relay) and an ohmic resistor, which are connected in series between a positive high-voltage potential and a negative high-voltage potential. Through the connection of the ohmic resistance, the capacitances are then discharged in a targeted manner, the discharge being faster the smaller the ohmic resistance. This active discharge can now take place centrally, the resistance value then being selected depending on the hardware configuration. This means that several decentrally distributed devices for active discharge can be dispensed with or can be dimensioned smaller.
In einer weiteren Ausführungsform sind mindestens einem Anschluss des Traktionsnetzes Schaltelemente zugeordnet, wobei das Steuergerät derart ausgebildet ist, in Abhängigkeit mindestens eines Zustandes die Schaltelemente zu öffnen, sodass gezielt situativ einzelne Hochvoltkomponenten vom Traktionsnetz abgetrennt werden können, was nachfolgend noch näher erläutert wird.In a further embodiment, switching elements are assigned to at least one connection of the traction network, the control device being designed to open the switching elements in dependence on at least one state, so that individual high-voltage components can be separated from the traction network in a targeted manner, which will be explained in more detail below.
In einer Ausführungsform ist der mindestens eine Anschluss mit zugeordneten Schaltelementen ein Anschluss einer DC-Ladebuchse, wobei das Steuergerät derart ausgebildet ist, die Schaltelemente mindestens während des Fahrbetriebes zu öffnen.In one embodiment, the at least one connection with associated switching elements is a connection of a DC charging socket, the control device being designed to open the switching elements at least during driving operation.
In einer weiteren Ausführungsform ist der mindestens eine Anschluss mit zugeordneten Schaltelementen ein Anschluss einer Komponente, die in einem crashgefährdeten Bereich angeordnet ist und für den Fahrbetrieb nicht benötigt wird, wobei das Steuergerät derart ausgebildet ist, während des Fahrbetriebes die Schaltelemente zu öffnen, sodass Kurzschlüsse in dem crashgefährdeten Bereich zu keinem Kurzschlussstrom führen.In a further embodiment, the at least one connection with associated switching elements is a connection of a component which is arranged in an area at risk of a crash and is not required for driving, the control device being designed to open the switching elements during driving so that short circuits occur do not lead to a short-circuit current in the area at risk of crash.
Alternativ oder kumulativ kann der Anschluss mit dem Schaltelementen ein Anschluss einer Komponente sein, die für das Laden nicht benötigt wird, wobei das Steuergerät derart ausgebildet ist, die Schaltelemente während des Ladens zu öffnen, um so Rückwirkungen auf den Ladebetrieb zu minimieren.Alternatively or cumulatively, the connection with the switching elements can be a connection of a component that is not required for charging, the control device being designed to open the switching elements during charging, in order to minimize repercussions on the charging operation.
In einer weiteren Ausführungsform ist mindestens zwei Anschlüssen eine Einrichtung zur Erfassung des Stromes zugeordnet und mindestens einem Anschluss eine Einrichtung zur Erfassung der Spannung zugeordnet, wobei das Steuergerät derart ausgebildet ist, in Abhängigkeit der Daten der Einrichtungen ein Energiemanagement durchzuführen oder zu veranlassen. Die Grundidee dabei ist, zentral den wirklichen Stromfluss in die Hochvoltkomponenten zu erfassen und durch geeignete Maßnahmen (z.B. Steuerbefehle an Steuergeräte der Hochvoltkomponenten) die Energieverteilung zu regeln. Alternativ können die Einrichtungen zur Erfassung des Stromes und der Spannung auch für andere Funktionen wie beispielsweise Kurzschlussüberwachung oder Isolationswiderstandsüberwachungen verwendet werden.In a further embodiment, at least two connections are assigned a device for detecting the current and at least one connection is assigned a device for detecting the voltage, the control device being designed to carry out or initiate energy management depending on the data of the devices. The basic idea here is to centrally record the actual current flow into the high-voltage components and to regulate the energy distribution using suitable measures (e.g. control commands on control units of the high-voltage components). Alternatively, the devices for detecting the current and the voltage can also be used for other functions such as short-circuit monitoring or insulation resistance monitoring.
In einer weiteren Ausführungsform weist der Traktionsnetzverteiler eine Kühleinrichtung für die Stromschienen auf. Durch das aktive Kühlen der Stromschienen innerhalb des Traktionsnetzverteilers kann über die elektrischen Verbindungen zu den Hochvoltkomponenten Wärme aus den Hochvoltkomponenten abgeführt werden. Die Kühleinrichtung ist beispielsweise als Wasserkühlung mit Wärmetauscher ausgebildet.In a further embodiment, the traction network distributor has a cooling device for the busbars. By actively cooling the busbars within the traction network distributor, heat can be dissipated from the high-voltage components via the electrical connections to the high-voltage components. The cooling device is designed, for example, as a water cooling system with a heat exchanger.
In einer weiteren Ausführungsform ist in dem Traktionsnetzverteiler mindestens eine Komponente zur HF-Entstörung angeordnet. Die Komponente kann dabei eine aktive Filterschaltung sein oder aber Y-Kondensatoren, die jeweils zwischen den Hochvolt-Potentialen und Masse angeordnet sind.In a further embodiment there is at least one in the traction network distributor RF interference suppression component arranged. The component can be an active filter circuit or Y capacitors, which are each arranged between the high-voltage potentials and ground.
In einer weiteren Ausführungsform ist mindestens ein Anschluss des Traktionsnetzverteilers ein Anschluss eines Unterverteilers. Dies erlaubt, beispielsweise verschiedene ausstattungsspezifische Komponenten an dem einen Unterverteiler anzuschließen, wobei bei Varianten ohne die ausstattungsspezifischen Komponenten einfach der Unterverteiler entfällt. Des Weiteren ermöglicht dies, zwei oder mehr Unterverteiler zu verwenden, die die Funktionalität eines Traktionsnetzverteilers aufweisen, die dann durch den zentralen Traktionsnetzverteiler überwacht werden. Dies erlaubt einen redundanten Aufbau eines Traktionsnetzes.In a further embodiment, at least one connection of the traction network distributor is a connection of a sub-distributor. This allows, for example, various equipment-specific components to be connected to the one sub-distributor, with sub-distributors simply being omitted in the case of variants without the equipment-specific components. Furthermore, this makes it possible to use two or more sub-distributors that have the functionality of a traction network distributor, which are then monitored by the central traction network distributor. This allows a redundant structure of a traction network.
In einer alternativen Ausführungsform ist das Steuergerät außerhalb des zentralen Traktionsnetzverteilers angeordnet, wobei jedoch die zuvor erwähnten Elemente weiterhin im zentralen Traktionsnetzverteiler angeordnet sind, wie beispielsweise die Einrichtung zur aktiven Entladung und/oder die Schaltelemente und/oder die Einrichtungen zur Erfassung von Strom und Spannung und/oder die Kühleinrichtung und/oder die Komponente zur HF-Entstörung. Diese werden dann durch das mindestens eine Steuergerät angesteuert.In an alternative embodiment, the control device is arranged outside the central traction network distributor, but the aforementioned elements are still arranged in the central traction network distributor, such as the device for active discharge and / or the switching elements and / or the devices for detecting current and voltage and / or the cooling device and / or the component for RF interference suppression. These are then controlled by the at least one control unit.
