Description
Die vorliegende Erfindung betrifft einen elektrischen Energiespeicher, insbesondere für ein Kraftfahrzeug, mit mehreren Batteriezellen, die miteinander verschaltet sind, gemäß dem Oberbegriff des Anspruchs 1. Die Erfindung betrifft außerdem ein mit einem derartigen elektrischen Energiespeicher ausgestattetes Kraftfahrzeug. The present invention relates to an electrical energy storage, in particular for a motor vehicle, with a plurality of battery cells, which are interconnected, according to the preamble of

Aufgrund der zunehmenden CO2-Belastung der Umwelt durch Verbrennungsmotoren von Kraftfahrzeugen geht die Entwicklung von Antrieben für Fahrzeuge zum Transport von Personen oder Gütern zunehmend in Richtung Elektro- oder Hybridantriebe. Als elektrischer Energiespeicher kommen hierbei insbesondere Lithium-Ionen-Batterien bzw. Lithium-Ionen-Batteriezellen zum Einsatz, die während des Lade- und Entladevorgangs Wärme erzeugen. Derartige Batteriezellen dürfen jedoch in keinem Fall eine maximale Zelltemperatur von 55 bis 80°C überschreiten, da hierdurch die Lebensdauer der einzelnen Batteriezellen stark beeinträchtigt wird. Bereits Zelltemperaturen von über 45°C beschleunigen den Alterungsprozess von Lithium-Ionen-Batterien deutlich. Zudem wirken sich auf große Temperaturgradienten innerhalb der Batteriezellen sowie zwischen den einzelnen Batteriezellen in einem Batteriemodul nachteilig auf die Lebensdauer aus. Es ist deshalb darauf zu achten, dass sich die Temperaturen der einzelnen Batteriezellen um nicht mehr als ±2 bis 5°C unterscheiden. Da bei üblichen Fahrzeugbatterien die einzelnen Batteriezellen in Reihe zueinander geschaltet sind, kann bereits eine defekte Zelle zu einem Totalausfall der gesamten Fahrzeugbatterie führen. Due to the increasing CO 2 pollution of the environment by internal combustion engines of motor vehicles, the development of drives for vehicles for the transport of persons or goods is increasingly in the direction of electric or hybrid drives. In particular, lithium-ion batteries or lithium-ion battery cells, which generate heat during the charging and discharging process, are used as the electrical energy store. However, such battery cells must in no case exceed a maximum cell temperature of 55 to 80 ° C, since this greatly affects the life of the individual battery cells. Already cell temperatures of over 45 ° C significantly accelerate the aging process of lithium-ion batteries. In addition, large temperature gradients within the battery cells as well as between the individual battery cells in a battery module have a disadvantageous effect on the service life. It is therefore important to ensure that the temperatures of the individual battery cells do not differ by more than ± 2 to 5 ° C. Since the individual battery cells are connected in series to each other in conventional vehicle batteries, even a defective cell can lead to a total failure of the entire vehicle battery.
Die vorliegende Erfindung beschäftigt sich daher mit dem Problem, für einen gattungsgemäßen elektrischen Energiespeicher eine verbesserte Ausführungsform anzugeben, die sich insbesondere durch eine erhöhte Leistung und eine verlängerte Lebensdauer auszeichnet. The present invention therefore deals with the problem of providing for a generic electrical energy storage an improved embodiment, which is characterized in particular by increased performance and a longer service life.
Dieses Problem wird erfindungsgemäß durch die Gegenstände der unabhängigen Ansprüche gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche. This problem is solved according to the invention by the subject matters of the independent claims. Advantageous embodiments are the subject of the dependent claims.
Die vorliegende Erfindung beruht auf dem allgemeinen Gedanken, einen elektrischen Energiespeicher eines Kraftfahrzeugs, bspw. eines Elektro- oder Hybridfahrzeugs, nicht wie bisher mittels einer einzigen Temperiereinrichtung zu kühlen, sondern zumindest zwei unterschiedliche Temperiereinrichtungen mit unterschiedlichen Temperierprinzipien vorzusehen, die zumindest zwei unterschiedliche Batteriezellen des elektrischen Energiespeichers auf unterschiedliche Art und Weise bedarfsgerecht temperieren, d. h. bspw. Heizen oder Kühlen. Durch die zumindest zwei unterschiedlichen Temperierkonzepte lassen sich einzelne Batteriezellen besonders bedarfsgerecht und individuell kühlen bzw. heizen, d. h. temperieren, wodurch deren Alterungsprozess verzögert und deren Leistungsfähigkeit gesteigert werden kann. Zudem kann mit dem individuellen Temperieren einzelner Batteriezellen auch eine Verringerung der Verlustleistung beim Entladen erreicht werden, woraus eine größere Reichweite sowie ein geringerer Kühlbedarf resultieren. Von besonderem Vorteil ist darüber hinaus, dass die Temperaturgradienten zwischen zwei unterschiedlichen Batteriezellen oder innerhalb des elektrischen Energiespeichers deutlich reduziert werden können, woraus wiederum eine Steigerung und Verlängerung der Lebensdauer resultiert. The present invention is based on the general idea of not cooling an electrical energy store of a motor vehicle, for example an electric or hybrid vehicle, by means of a single tempering device, but providing at least two different tempering devices with different tempering principles, comprising at least two different battery cells of the electric motor Heat energy storage in different ways as needed, d. H. eg heating or cooling. By means of the at least two different temperature control concepts, individual battery cells can be cooled and / or heated in a particularly demand-oriented and individual manner, ie. H. tempering, whereby their aging process can be delayed and their performance can be increased. In addition, with the individual tempering of individual battery cells, a reduction of the power loss during discharge can be achieved, resulting in a greater range and a lower cooling requirement. Of particular advantage, moreover, that the temperature gradient between two different battery cells or within the electrical energy storage can be significantly reduced, which in turn results in an increase and extension of life.
Bei einer vorteilhaften Weiterbildung der erfindungsgemäßen Lösung sind die zumindest zwei unterschiedlichen Temperiereinrichtungen aus den nachfolgend aufgezählten Temperiereinrichtungen entnommen: Luftkühler/-heizung, Flüssigkühler/-heizung, Bodenkühler/-heizung, Kopfkühler/-heizung, Seitenkühler/-heizung oder Ableiterkühler/-heizung. Bereits diese Aufzählung lässt erahnen, dass zur bedarfsgerechten Kühlung des elektrischen Energiespeichers und insbesondere zur bedarfsgerechten Kühlung einzelner Batteriezellen des elektrischen Energiespeichers unterschiedlichste Temperierkonzepte, d. h. insbesondere auch unterschiedliche Kühlkonzepte zum Einsatz kommen können, wodurch ein besonders effektives Thermomanagement erzielt werden kann. Dabei ist bspw. denkbar, dass lediglich der Kopf- und Bodenkühler zum Einsatz kommen oder aber der Seitenkühler bzw. die jeweils zugehörige Heizung. Hierdurch kann eine punktuelle und partielle Kühlung bzw. Temperierung des elektrischen Energiespeichers und dessen Batteriezellen erreicht werden, wobei selbstverständlich auch denkbar ist, dass die einzelnen Batteriezellen von unterschiedlichen Temperiereinrichtungen temperiert und dadurch mit unterschiedlichen Temperaturen beaufschlagt werden. In an advantageous development of the solution according to the invention, the at least two different tempering devices are taken from the tempering devices listed below: air cooler / heater, liquid cooler / heater, floor cooler / heater, head cooler / heater, side cooler / heater or diverter cooler / heater. Already this enumeration suggests that for the needs-oriented cooling of the electrical energy storage and especially for demand cooling of individual battery cells of the electrical energy storage a wide variety of temperature control, ie in particular different cooling concepts can be used, creating a particularly effective thermal management can be achieved. It is, for example, conceivable that only the top and bottom radiator are used or the side radiator or the respective associated heating. In this way, a point and partial cooling or temperature control of the electrical energy storage and its battery cells can be achieved, it being understood that it is also conceivable that the individual battery cells are tempered by different tempering and thereby acted upon with different temperatures.
Zweckmäßig weisen die zumindest zwei unterschiedlichen Temperiereinrichtungen unterschiedliche Kühl- und/oder Heizleistungen und/oder unterschiedliche Kühl-/Heiztemperaturen auf. So ist bspw. denkbar, dass bis zu einer vorgegebenen Grenztemperatur eine erste Temperiereinrichtung das Temperieren, d. h. Kühlen oder Heizen übernimmt, wogegen ab dieser Grenztemperatur zusätzlich oder alternativ die zweite Temperiereinrichtung zugeschaltet wird. Dies kann bspw. auch durch Zu- oder Abschalten einzelner Kühlkreisläufe, die zu jeweiligen Temperiereinrichtungen gehören, erfolgen. Suitably, the at least two different tempering devices have different cooling and / or heating powers and / or different cooling / heating temperatures. Thus, for example, it is conceivable that up to a predetermined limit temperature, a first temperature control, the temperature control, d. H. Cooling or heating takes over, in addition or alternatively, the second tempering is switched on from this limit temperature. This can also be done, for example, by connecting or disconnecting individual cooling circuits that belong to respective temperature control devices.
Weitere wichtige Merkmale und Vorteile der Erfindung ergeben sich aus den Unteransprüchen, aus der Zeichnung und aus der zugehörigen Figurenbeschreibung anhand der Zeichnung. Other important features and advantages of the invention will become apparent from the dependent claims, from the drawing and from the associated description of the figures with reference to the drawing.
Es versteht sich, dass die vorstehend genannten und die nachstehend noch zu erläuternden Merkmale nicht nur in der jeweils angegebenen Kombination, sondern auch in anderen Kombinationen oder in Alleinstellung verwendbar sind, ohne den Rahmen der vorliegenden Erfindung zu verlassen. It is understood that the features mentioned above and those yet to be explained below can be used not only in the particular combination given, but also in other combinations or in isolation, without departing from the scope of the present invention.
