Erfindungsgemäß weist ein erstes Batteriemodul (2) im Vergleich zu den beiden verbleibenden Batteriemodulen (3, 4) eine verhältnismäßig kleine elektrische Kapazität, einen geringen Memoryeffekt und im Betrieb einen verhältnismäßig großen Temperierbedarf auf. Ein zweites Batteriemodul (3) weist im Vergleich zum ersten Batteriemodul (2) und zu einem dritten Batteriemodul (4) eine mittlere elektrische Kapazität und im Betrieb einen mittleren Temperierbedarf auf. Das dritte Batteriemodul (4) weist im Vergleich zu den beiden verbleibenden Batteriemodulen (2, 3) eine verhältnismäßig große elektrische Kapazität und im Betrieb einen verhältnismäßig kleinen Temperierbedarf auf. Ausschließlich das erste Batteriemodul (2) ist mit elektrischen Verbrauchern (6.1 bis 6.n) des Fahrzeugs und einer Ladevorrichtung (7) elektrisch gekoppelt und die drei Batteriemodule (2 bis 4) sind derart elektrisch verschaltet sind, dass das zweite Batteriemodul (3) von dem ersten Batteriemodul (2) aufladbar und entladbar ist und das dritte Batteriemodul (4) von dem zweiten Batteriemodul (3) aufladbar und entladbar ist.Die Erfindung betrifft weiterhin ein Verfahren zum Betrieb eines Batteriesystems (1) für ein Fahrzeug.The invention relates to a battery system (1) for a vehicle with three electrically interconnected battery modules (2 to 4) and a temperature control device (5) for selective temperature control of the battery modules (2 to 4). According to the invention, a first battery module (2) has, compared to the two remaining battery modules (3, 4), a relatively small electrical capacity, a low memory effect and a relatively large temperature control requirement during operation. A second battery module (3) has, in comparison to the first battery module (2) and a third battery module (4), an average electrical capacity and, during operation, an average temperature control requirement. The third battery module (4) has a relatively large electrical capacity compared to the two remaining battery modules (2, 3) and a relatively small temperature control requirement during operation. Only the first battery module (2) is electrically coupled to electrical consumers (6.1 to 6.n) of the vehicle and a charging device (7) and the three battery modules (2 to 4) are electrically connected in such a way that the second battery module (3) can be charged and discharged by the first battery module (2) and the third battery module (4) can be charged and discharged by the second battery module (3). The invention further relates to a method for operating a battery system (1) for a vehicle.

Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous refinements of the invention are the subject matter of the subclaims.
Ein Batteriesystem für ein Fahrzeug weist drei elektrisch miteinander verschaltete Batteriemodule und eine Temperiervorrichtung zur selektiven Temperierung der Batteriemodule auf.A battery system for a vehicle has three electrically interconnected battery modules and a temperature control device for selective temperature control of the battery modules.
Erfindungsgemäß weist ein erstes Batteriemodul im Vergleich zu den beiden verbleibenden Batteriemodulen eine verhältnismäßig kleine elektrische Kapazität, einen geringen Memoryeffekt und im Betrieb einen verhältnismäßig großen Temperierbedarf auf. Weiterhin weist ein zweites Batteriemodul im Vergleich zum ersten Batteriemodul und zu einem dritten Batteriemodul eine mittlere elektrische Kapazität und im Betrieb einen mittleren Temperierbedarf auf. Das dritte Batteriemodul weist im Vergleich zu den beiden verbleibenden Batteriemodulen eine verhältnismäßig große elektrische Kapazität und im Betrieb einen verhältnismäßig kleinen Temperierbedarf auf. Dabei ist ausschließlich das erste Batteriemodul mit elektrischen Verbrauchern des Fahrzeugs und einer Ladevorrichtung elektrisch gekoppelt und die drei Batteriemodule sind derart elektrisch verschaltet, dass das zweite Batteriemodul von dem ersten Batteriemodul aufladbar und entladbar ist und das dritte Batteriemodul von dem zweiten Batteriemodul aufladbar und entladbar ist.According to the invention, in comparison to the two remaining battery modules, a first battery module has a relatively small electrical capacity, a low memory effect and a relatively large temperature control requirement during operation. Furthermore, in comparison to the first battery module and to a third battery module, a second battery module has an average electrical capacity and an average temperature control requirement during operation. In comparison to the two remaining battery modules, the third battery module has a relatively large electrical capacity and a relatively small temperature control requirement during operation. Only the first battery module is electrically coupled to electrical loads of the vehicle and a charging device, and the three battery modules are electrically connected in such a way that the second battery module can be charged and discharged by the first battery module and the third battery module can be charged and discharged by the second battery module.
Vorliegend werden unter Batterien elektrische Energiespeicher verstanden, welche zumindest einen Akkumulator umfassen, der als galvanisches wiederaufladbares Element ausgebildet ist.In the present case, batteries are understood to mean electrical energy stores which comprise at least one accumulator which is designed as a galvanic, rechargeable element.
Batterien, welche schnell elektrische Energie aufnehmen und/oder abgeben können, müssen häufig komplex gekühlt werden und erfordern daher mehr Bauraum und führen zu einem höheren Gewicht. Zusätzlich wird eine Effizienz verringert, weil eine zur Temperierung der Batterie erforderliche Energie nicht für einen eigentlichen Zweck, beispielsweise eine Fahrzeugbewegung, genutzt werden kann.Batteries, which can quickly absorb and / or deliver electrical energy, often have to be cooled in a complex manner and therefore require more installation space and lead to a higher weight. In addition, efficiency is reduced because the energy required to control the temperature of the battery cannot be used for an actual purpose, for example moving the vehicle.
Das vorliegende Batteriesystem zeichnet sich dadurch aus, dass diesem mit elektrischen Verbrauchern schnell elektrische Energie entnommen und dass dieses schnell elektrisch geladen werden kann, ohne im selben Umfang eine Volumen und Gewicht des Batteriesystems vergrößern zu müssen. Das heißt, dass Batteriesystem stellt einen verbesserten Kompromiss zwischen Gewicht, Leistung und Speicherkapazität dar. Weiterhin können für das dritte Batteriemodul besonders kostengünstige Akkumulatoren verwendet werden. Auch sind zumindest die Akkumulatoren des zweiten und dritten Batteriemoduls in einfacher Weise austauschbar.The present battery system is characterized in that electrical energy is quickly drawn from it with electrical consumers and that it can be electrically charged quickly without having to increase the volume and weight of the battery system to the same extent. This means that the battery system represents an improved compromise between weight, performance and storage capacity. Furthermore, particularly inexpensive accumulators can be used for the third battery module. At least the accumulators of the second and third battery modules can also be exchanged in a simple manner.
