Description
Die Erfindung betrifft eine Temperiervorrichtung für eine elektrische Batterie.The invention relates to a tempering device for an electric battery.
Aus dem Stand der Technik sind allgemein elektrische Energiespeicher, auch als elektrische Batterie bezeichnet, für Fahrzeuganwendungen bekannt. Beispielsweise sind solche Batterien als so genannte Hochvoltbatterien ausgebildet, welche während ihres Betriebs aufgrund eines elektrischen Innenwiderstandes Verluste in Form von Wärme erzeugen. Ein zuverlässiger Betrieb einer solchen Batterie mit hohem Wirkungsgrad ist jedoch nur in einem bestimmten Temperaturbereich möglich. Aus diesem Grund existieren verschiedene Vorrichtungen zur Temperierung einer Batterie, bei welchen Einzelzellen der Batterie mittels Luftkühlung, Flüssigkühlung oder einer Kombination daraus temperiert werden.From the prior art, electrical energy storage devices, also known as electric batteries, are generally known for vehicle applications. For example, such batteries are designed as so-called high-voltage batteries, which generate losses in the form of heat during their operation due to an internal electrical resistance. However, a reliable operation of such a battery with high efficiency is possible only in a certain temperature range. For this reason, there are various devices for controlling the temperature of a battery, in which individual cells of the battery by means of air cooling, liquid cooling or a combination thereof are tempered.

Die erfindungsgemäße Temperiervorrichtung für eine elektrische Batterie mit zumindest einer Einzelzelle umfasst ein Batteriegehäuse, einen Wärmetauscher und einen innerhalb des Batteriegehäuses befindlichen Vorrat an Temperierflüssigkeit, in welchen die zumindest eine Einzelzelle teilweise eintaucht, wobei die Temperierflüssigkeit bei einer vorgegebenen Temperatur an der zumindest einen Einzelzelle und/oder an zumindest einer thermisch mit der zumindest einen Einzelzelle gekoppelten Temperierkomponente verdunstet. Verdunstete Temperierflüssigkeit ist dem Wärmetauscher zu einer Kondensation zuführbar. Die Temperiervorrichtung umfasst weiterhin zumindest eine Förderpumpe zur Förderung der Temperierflüssigkeit aus dem Vorrat und eine innerhalb des Batteriegehäuses angeordnete und mit der Förderpumpe gekoppelte Vorrichtung zur Zerteilung der Temperierflüssigkeit und zur Beaufschlagung eines aus dem Vorrat ragenden Abschnitts der zumindest einen Einzelzelle mit zerteilter Temperierflüssigkeit.The tempering device according to the invention for an electric battery having at least one individual cell comprises a battery housing, a heat exchanger and a supply of tempering liquid contained within the battery housing, in which the at least one individual cell partially immersed, wherein the tempering at a predetermined temperature at the at least one individual cell and / / or evaporated at least one thermally coupled to the at least one single cell tempering. Evaporated bath liquid can be fed to the heat exchanger for condensation. The tempering device further comprises at least one feed pump for conveying the tempering liquid from the supply and a device arranged within the battery housing and coupled to the feed pump for dividing the bath and for acting on a protruding from the stock portion of the at least one single cell with zerteilter bath liquid.
Die erfindungsgemäße Temperiervorrichtung ermöglicht eine Anwendung einer Verdunstungskühlung für alle Formen von Einzelzellen, insbesondere auch für Flachzellen, beispielsweise so genannte Hardcase- und so genannte Pouchzellen. Dabei erfolgt die Kühlung der Einzelzellen besonders homogen sowie effizient. Weiterhin ist in besonders vorteilhafter Weise eine erforderliche Menge an Temperierflüssigkeit verringert.The temperature control device according to the invention allows the use of evaporative cooling for all forms of single cells, in particular also for flat cells, for example so-called hardcase and so-called pouch cells. The cooling of the individual cells is particularly homogeneous and efficient. Furthermore, a required amount of heat transfer liquid is reduced in a particularly advantageous manner.
