Abstract
Description
Die Erfindung betrifft ein Batteriesystem mit mehreren Batterieeinheiten und einer Steuereinheit zur Steuerung eines Ein- und Abschaltens von Batterieeinheiten sowie ein Verfahren zum Betrieb eines derartigen Batteriesystems.The The invention relates to a battery system with a plurality of battery units and a control unit for controlling power on and off of battery units and a method of operating such Battery system.
Batterien zum Antrieb von Kraftfahrzeugen, insbesondere von größeren Hybridfahrzeugen oder Elektrofahrzeugen, erlauben das Zurücklegen von nur relativ geringen Entfernungen bis ein erneutes Batterieaufladen nötig wird. Zur Vergrößerung der Reichweiten derartiger Kraftfahrzeuge können mehrere Batterieeinheiten kombiniert werden.batteries for driving motor vehicles, especially larger ones Hybrid vehicles or electric vehicles, allow the replacement from relatively short distances to recharging the battery becomes necessary. To increase the ranges such motor vehicles can have multiple battery units be combined.

Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.advantageous Embodiments of the invention are the subject of the dependent claims.
Bei dem erfindungsgemäßen Verfahren zum Betrieb eines Batteriesystems mit mehreren Batterieeinheiten und einer Steuereinheit zur Steuerung eines Ein- und Abschaltens von Batterieeinheiten wird zu jedem Zeitpunkt höchstens eine der Batterieeinheiten eingeschaltet und die jeweils einzuschaltende Batterieeinheit in Abhängigkeit von Betriebskenngrößen der Batterieeinheiten ausgewählt.at the inventive method for operating a Battery system with multiple battery units and a control unit to control a switching on and off of battery units becomes at most one of the battery units is switched on at each time and the respective battery unit to be switched in dependence selected from operating characteristics of the battery units.
Unter dem Einschalten einer Batterieeinheit wird dabei das elektrische Anschließen der Batterieeinheit an einen mit dem Batteriesystem zu betreibenden elektrischen Verbraucher verstanden. Unter dem Abschalten einer Batterieeinheit wird dementsprechend die elektrische Entkopplung der Batterieeinheit von dem elektrischen Verbraucher verstanden.Under turning on a battery unit while the electrical Connecting the battery unit to one with the battery system understood to be operated electrical loads. Under the shutdown a battery unit is accordingly the electrical decoupling the battery unit understood by the electrical consumer.
Durch das Einschalten höchstens einer Batterieeinheit zu jedem Zeitpunkt wird vorteilhaft eine gleichzeitige Entladung mehrerer Batterieeinheiten vermieden, so dass die jeweils abgeschalteten Batterieeinheiten geschont werden und beispielsweise aufgeladen werden und/oder abkühlen oder abgekühlt werden können. Durch die Auswahl der jeweils einzuschaltenden Batterieeinheit in Abhängigkeit von Betriebskenngrößen der Batterieeinheiten kann vorteilhaft zum Betrieb eines Verbrauchers jeweils eine Batterieeinheit genutzt werden, die sich aufgrund der Betriebskenngrößen dazu besonders eignet, beispielsweise aufgrund ihres Ladungszustandes und/oder ihrer Batterietemperatur. Auf diese Weise kann insbesondere der Verschleiß der Batterieeinheiten reduziert und ihre Lebensdauer erhöht werden. Ferner kann mit dem erfindungsgemäßen Verfahren die negative Auswirkung eines Ausfalls einer Batterieeinheit reduziert werden, indem der Ausfall mittels der Betriebskenngrößen erkannt wird und diese Batterieeinheit nicht mehr eingesetzt wird.By turning on at most one battery unit to each Time will be beneficial a simultaneous discharge of several Battery units avoided, so that each disconnected Battery units are spared and charged, for example be and / or cool or cooled can. By selecting the respective one to be activated Battery unit depending on operating parameters The battery units can be advantageous for the operation of a consumer each use a battery unit, which is due to the operating characteristics this is particularly suitable, for example due to their charge state and / or their battery temperature. In this way, in particular the Wear of the battery units is reduced and their life span increase. Furthermore, with the inventive Method the negative impact of a failure of a battery unit be reduced by the failure by means of the operating parameters is detected and this battery unit is no longer used.
Ein erfindungsgemäßes Batteriesystem weist mehrere Batterieeinheiten und eine Steuereinheit zur Steuerung eines Ein- und Abschaltens von Batterieeinheiten sowie jeweils einen Trennschütz für jede Batterieeinheit zu deren Ein- und Abschaltung und mit der Steuereinheit verbundene Erfassungseinheiten zur Erfassung von Betriebskenngrößen der Batterieeinheiten auf.One Inventive battery system has several Battery units and a control unit for controlling a and shutdown of battery units and each a contactor for each battery unit for their switching on and off and Detection units connected to the control unit for detection of operating characteristics of the battery units.
Die Trennschütze ermöglichen vorteilhaft eine sichere Ein- und Abschaltung der Batterieeinheiten.The Isolating contactors advantageously allow a safe Switching the battery units on and off.
