Description
Die Erfindung betrifft eine Batterieeinheit, aufgebaut aus einer Vielzahl von Batterieeinzelzellen mit einem Gehäuse und mit einer Kühlvorrichtung. The invention relates to a battery unit, constructed from a plurality of battery individual cells with a housing and with a cooling device.
Die absehbare Zunahme von Fahrzeugen im Straßenverkehr mit Elektro- oder Hybridantrieben hat die Entwicklung von dafür notwendigen Hochvoltbatterien beschleunigt. Beim Lade- bzw. Entladevorgang bei solchen Batterien bzw. Batterieeinheiten entsteht allerdings hohe Verlustwärme, so dass die sich erwärmenden Einzelzellen bzw. die Batterieeinheit möglichst gleichmäßig gekühlt werden müssen. Andernfalls besteht die Gefahr, dass es zur Überhitzung kommt bzw. dass sich die Eigenschaften der Batterien bzw. der Batterieeinheit verschlechtern, z.B. insbesondere die Lebensdauer verkürzt wird und auch andere Batterieeigenschaften sich nachteilig entwickeln. The foreseeable increase in road vehicles with electric or hybrid drives has accelerated the development of high-voltage batteries required for this purpose. When charging or discharging in such batteries or battery units, however, high heat loss occurs, so that the heating individual cells or the battery unit must be cooled as uniformly as possible. Otherwise, there is a risk of overheating or deterioration of the characteristics of the batteries or battery pack, e.g. in particular the service life is shortened and also other battery properties develop disadvantageously.
Neben den Herausforderungen, die aus dem technischen Aufbau der Batteriezellen als solche resultieren, liegt eine weitere Herausforderung darin, solche Batterieeinheiten möglichst einfach, platzsparend-kompakt aufzubauen und gleichzeitig für eine optimale Wärmeabfuhr im Betrieb zu sorgen. In addition to the challenges that result from the technical design of the battery cells as such, another challenge is to build such battery units as simple as possible, compact in space and at the same time to ensure optimal heat dissipation during operation.
Aus dem Stand der Technik sind eine Vielzahl von Lösungen dazu bekannt geworden. So offenbart die

Der Erfindung liegt – wie bereits eingangs erwähnt – die Aufgabe zugrunde, eine Batterieeinheit möglichst einfach und kostengünstig aufzubauen und dabei eine Lösung anzubieten, die neben einer sicheren Fixierung und Positionierung der Einzelzellen im Zellverbund eine möglichst effiziente und gleichmäßige Kühlung gewährleistet. The invention is - as already mentioned - the task of building a battery unit as simple and inexpensive as possible while offering a solution that ensures the most efficient and uniform cooling in addition to a secure fixation and positioning of the individual cells in the cell assembly.
Diese Aufgabe wird mit der Erfindung dadurch gelöst, dass die Batterieeinzelzellen als Rundzellen mit Kontaktierungspolen ausschließlich an einem zur mechanischen Fixierung und Positionierung der Rundzelle im Gehäuse dienenden Ende der Rundzelle ausgeführt sind, wobei das Gehäuse die Rundzellen als mit Kühlmedium durchströmten Kühlmantel im Wesentlichen umschließt. This object is achieved with the invention in that the battery individual cells are designed as round cells with Kontaktierungspolen exclusively on a serving for mechanical fixation and positioning of the round cell in the housing end of the round cell, wherein the housing surrounds the round cells as a cooling medium flowed through cooling jacket substantially.
Als Kühlmedium kann dabei vorzugsweise Wasser, aber alternativ auch ein Öl oder Luft, Verwendung finden. As a cooling medium can preferably be found water, but alternatively also an oil or air, use.
Zum sicheren Aufbau der Batterieeinheit können die einzelnen Rundzellen in das Gehäuse formschlüssig und/oder kraftschlüssig einsetzbar sein. Dazu können z. B. im Gehäuse unterteilt entsprechende Aufnahmen ausgeformt sein. For safe construction of the battery unit, the individual round cells can be used in the housing positively and / or non-positively. These can z. B. in the housing be formed corresponding receptacles.
Zur Erhöhung der elektrischen Sicherheit ist es zweckmäßig, dass nach dem Einsetzen der Rundzellen in das Gehäuse zur elektrischen Isolation die Rundzellen mit einer isolierenden Lackschicht überzogen werden. Alternativ können auch Kunststoff oder Keramik als Isolationsmaterial verwendet werden. To increase the electrical safety, it is expedient that after inserting the round cells in the housing for electrical insulation, the round cells are coated with an insulating lacquer layer. Alternatively, plastic or ceramic can be used as insulation material.
Der Gegenstand der Erfindung weist eine Reihe von Vorteilen auf. Insbesondere erfolgt, aufgrund der einseitigen Anbindung der Rundzellen im oberen Teil, nur ein geringer Wärmeeintrag auf die Zellschichten im Inneren, da sich diese eher im unteren Teil der Zelle befinden. Zudem ist bei einseitiger Anbindung kein Toleranzausgleich notwendig. Grundsätzlich könnten dabei nicht nur Rundzellen, sondern auch prismatische Zellen mit festem Gehäuse den vorgeschlagenen Aufbau nutzen. The object of the invention has a number of advantages. In particular, due to the unilateral connection of the round cells in the upper part, only a small amount of heat is applied to the cell layers in the interior, since these are located more in the lower part of the cell. In addition, with one-sided connection no tolerance compensation is necessary. In principle, not only round cells, but also prismatic cells with a solid housing could use the proposed structure.
Weitere Merkmale und Einzelheiten des Gegenstands der Erfindung werden nachfolgend anhand in der Zeichnung schematisch dargestellter Ausführungsbeispiele näher beschrieben. Further features and details of the subject matter of the invention will become apparent below described in detail in the drawing schematically illustrated embodiments.
