Die Erfindung betrifft einen elektrischen Energiespeicher eines Kraftfahrzeugs, insbesondere einen Hochvoltenergiespeicher eines Hybridfahrzeugs oder eines Elektrofahrzeugs, nach dem Oberbegriff des Patentanspruchs 1. Des Weiteren betrifft die Erfindung ein Kraftfahrzeug, insbesondere ein Hybridfahrzeug oder Elektrofahrzeug, nach dem Oberbegriff des Patentanspruchs 6.The invention relates to an electrical energy accumulator of a motor vehicle, in particular a high-voltage energy storage of a hybrid vehicle or an electric vehicle, according to the preamble of claim 1. Furthermore, the invention relates to a motor vehicle, in particular a hybrid vehicle or electric vehicle, according to the preamble of patent claim.
In einem Hybridfahrzeug oder in einem Elektrofahrzeug kommen als Hochvoltenergiespeicher ausgebildete elektrische Energiespeicher zum Einsatz, die im motorischen Betrieb einer elektrischen Maschine des Hybridfahrzeugs oder Elektrofahrzeugs stärker entladen und im generatorischen Betrieb der jeweiligen elektrischen Maschine stärker aufgeladen werden. Elektrische Energiespeicher verfügen über ein Gehäuse und im Gehäuse aufgenommene Speichermodule.In a hybrid vehicle or in an electric vehicle designed as a high-voltage storage electric energy storage devices are used, which are more discharged in the engine operation of an electric machine of the hybrid vehicle or electric vehicle and more charged in the regenerative operation of the respective electric machine. Electrical energy storage devices have a housing and memory modules accommodated in the housing.
Bei Ladevorgängen sowie Entladevorgängen eines elektrischen Energiespeichers fließen elektrische Ströme, in Folge derer der elektrische Energiespeicher einer Erwärmung unterliegt. Um eine möglichst hohe Lebensdauer eines elektrischen Energiespeichers zu gewährleisten, darf derselbe nicht zu stark erhitzt werden. Daher ist es aus der Praxis bereits bekannt, elektrische Energiespeicher zu kühlen.When charging and discharging an electrical energy storage flow electrical currents, as a result of which the electrical energy storage is subject to heating. To ensure the longest possible life of an electrical energy store, the same may not be heated too much. Therefore, it is already known from practice to cool electrical energy storage.
Zur Kühlung von elektrischen Energiespeichern wird nach der Praxis derzeit so vorgegangen, dass der elektrische Energiespeicher an einem Kühlkreislauf eines Kühlmittels gekoppelt ist, wobei das Kühlmittel zur Kühlung des elektrischen Energiespeichers durch Abschnitte desselben geleitet wird. Eine solche Kühlung eines elektrischen Energiespeichers ist konstruktiv aufwendig. Es besteht daher Bedarf an einem elektrischen Energiespeichers eines Kraftfahrzeugs mit einer einfachen und effektiven Kühlung.For cooling of electrical energy storage is currently proceeding according to the practice that the electrical energy storage is coupled to a cooling circuit of a coolant, wherein the coolant for cooling the electrical energy storage is passed through the same sections. Such cooling of an electrical energy storage is structurally complex. There is therefore a need for an electrical energy storage device of a motor vehicle with a simple and effective cooling.
Hiervon ausgehend liegt der hier vorliegenden Erfindung die Aufgabe zugrunde, einen neuartigen elektrischen Energiespeicher eines Kraftfahrzeugs sowie ein neuartiges Kraftfahrzeug mit einem solchen elektrischen Energiespeicher zu schaffen.On this basis, the present invention has the object to provide a novel electrical energy storage of a motor vehicle and a novel motor vehicle with such an electrical energy storage.
Die Aufgabe wird durch einen elektrischen Energiespeicher gemäß Patentanspruch 1 gelöst. Der erfindungsgemäße elektrische Energiespeicher umfasst mindestens eine Sprüheinrichtung, mit Hilfe derer auf mindestens eine von Fahrtwind überströmte Gehäusewand des Gehäuses zu verdampfendes Kühlmittel sprühbar ist.The object is achieved by an electrical energy storage device according to claim 1. The electrical energy storage device according to the invention comprises at least one spraying device with the aid of which coolant can be sprayed on at least one housing wall of the housing to be vaporized by the wind.
Mit der hier vorliegenden Erfindung wird erstmals vorgeschlagen, zur Kühlung eines elektrischen Energiespeichers eine Gehäusewand eines Gehäuses des elektrischen Energiespeichers, die von Fahrtwind überströmt ist, mit einem zu verdampfenden Kühlmittel zu besprühen. Die Verdampfung bewirkt eine endotherme Reaktion und sorgt für eine effektive Kühlung des elektrischen Energiespeichers an der von Fahrtwind überströmten und mit dem zu verdampfenden Kühlmittel besprühten Gehäusewand des Gehäuses. Diese Kühlung ist konstruktiv einfach, kostengünstig und besonders effektiv.With the present invention, it is proposed for the first time to spray a housing wall of a housing of the electrical energy store, which is overflowed by airflow, with a coolant to be evaporated in order to cool an electrical energy store. The evaporation causes an endothermic reaction and ensures effective cooling of the electrical energy storage at the overflowed by wind and sprayed with the evaporating coolant housing wall of the housing. This cooling is structurally simple, inexpensive and particularly effective.
Vorzugsweise ist die oder jede Sprüheinrichtung einem in Fahrtwindrichtung gesehen stromaufwärtigen Abschnitt der jeweiligen mit dem zu verdampfendem Kühlmittel zu besprühenden Gehäusewand zugeordnet ist, wobei eine Sprührichtung der oder jeder Sprüheinrichtung in Fahrtwindrichtung gerichtet ist, und wobei die jeweilige zu besprühende Gehäusewand in der Einbausituation des Energiespeichers im Bereich eines Unterbodens des Kraftfahrzeugs in etwas waagrecht verläuft. Diese Ausgestaltung des elektrischen Energiespeichers ist besonders einfach und daher besonders bevorzugt Die mit dem zu verdampfenden Kühlmittel zu besprühende Gehäusewand erstreckt sich im Bereich eines Unterbodens des Kraftfahrzeugs in etwa waagrecht und ist demnach von Fahrtwind überströmt. Von der oder jeder Sprüheinrichtung versprühtes Kühlmittel wird aufgrund der Positionierung der Sprüheinrichtung, der Sprührichtung derselben und der Fahrtwindrichtung über den Fahrtwind gleichmäßig über die zu besprühende Gehäusewand verteilt und sorgt so über die gesamte besprühte Gehäusewand des Gehäuses des elektrischen Energiespeichers für eine gleichmäßige und effektive Kühlung desselben.Preferably, the or each spraying device is associated with an upstream in the direction of air flow upstream portion of the respective sprayed with the evaporating coolant housing wall, wherein a spray direction of the or each spray device is directed in the wind direction, and wherein the respective housing wall to be sprayed in the installation situation of the energy storage in Area of a subfloor of the motor vehicle in something horizontal runs. This embodiment of the electrical energy storage device is particularly simple and therefore particularly preferred. The housing wall to be sprayed with the coolant to be vaporized extends approximately horizontally in the region of a subfloor of the motor vehicle and is therefore overflowed by the wind. Coolant sprayed by the or each sprayer is evenly distributed over the housing wall to be sprayed, due to the positioning of the sprayer, the spray direction thereof, and the airflow direction over the airflow, thus providing uniform and effective cooling over the entire sprayed housing wall of the electrical energy store housing ,
Das erfindungsgemäße Kraftfahrzeug ist in Patentanspruch 6 definiert.The motor vehicle according to the invention is defined in claim 6.
