Abstract
Description
Die Erfindung betrifft eine Batterie mit einem Zellverbund mehrerer Batteriezellen.The The invention relates to a battery having a cell group of several Battery cells.
Üblicherweise weist eine Batterie zur Anwendung in Kraftfahrzeugen, insbesondere in Kraftfahrzeugen mit einem Hybridantrieb oder Brennstoffzellen-Fahrzeugen, einen Zellblock aus mehreren elektrisch in Reihe und/oder parallel geschalteten Batteriezellen, beispielsweise Lithium-Ionen-Zellen, auf.Usually has a battery for use in motor vehicles, in particular in motor vehicles with a hybrid drive or fuel cell vehicles, a cell block of several electrically in series and / or in parallel switched battery cells, such as lithium-ion cells, on.
Die Batteriezellen müssen gekühlt werden, um die entstehende Verlustwärme abzuführen. Dazu wird in der Regel eine Flüssigkeitskühlung oder eine Kühlung mittels vorgekühlter Luft, die zwischen die Zellen geleitet wird, eingesetzt.The Battery cells must be cooled to avoid the resulting Dissipate heat loss. This is usually done a liquid cooling or a cooling by means of pre-cooled air, which is passed between the cells is used.
Bei der aus Bauraumgründen bevorzugten Flüssigkeitskühlung ist am Zellblock der Batterie eine Kühlplatte mit wenigstens einem von einer Kühlflüssigkeit, beispielsweise einem Wasser-Glykol-Gemisch, durchströmter Kühlkanal angeordnet. Längs der Batteriezellen wird die Wärme häufig durch separate Wärmeleitelemente, beispielsweise Wärmeleitstäbe oder -bleche, zur Kühlplatte geleitet. Dabei sind die Wärmeleitelemente bevorzugt fest mit der Kühlplatte verbunden, um zu dieser einen guten Wärmekontakt herzustellen.at the preferred for space reasons liquid cooling is at the cell block of the battery a cooling plate with at least one of a cooling liquid, for example a water-glycol mixture, flowed through cooling channel arranged. Along the battery cells is the heat often by separate Wärmeleitelemente, for example Thermal conductors or sheets, to the cooling plate directed. The heat-conducting elements are preferably fixed connected to the cooling plate to get to this one good Make thermal contact.
Zwischen den Batteriezellen und den Wärmeleitelementen verbleiben infolge von Fertigungstoleranzen jedoch Spalte, welche die Wärmeableitung reduzieren. Deshalb werden die Spalte gegenwärtig beispielsweise durch Kunststoffvergussmasse geschlossen.Between remain the battery cells and the heat conducting elements however, due to manufacturing tolerances, gaps which reduce heat dissipation. Therefore, the columns are currently going through, for example Closed plastic potting compound.
Ein derartiger Verschluss der Spalte hat jedoch eine Reihe von Nachteilen. Zum einen hat die Kunststoffvergussmasse eine relativ geringe Wärmeleitfähigkeit. Ferner ist sie schwierig in die kleinen Spalten vergießbar und daher aufwändig zu verarbeiten. Außerdem weist sie nach ihrer Aushärtung eine andere Wärmeausdehnung als andere Bauteile der Batterie auf, wodurch Temperaturschwankungen eine Rissbildung in der Kunststoffvergussmasse und/oder eine teilweise Ablösung der Kunststoffvergussmasse von einem Bauteil verursachen können. Kunststoffvergussmasse ist zudem teuer und brandgefährlich. Schließlich ist ein Austauschen defekter Batteriezellen oder eine Zerlegung der Batterie zur Entsorgung nach dem Verguss des Zellblocks mit Kunststoffvergussmasse nicht bzw. nur mit einem hohen Aufwand möglich.One however, such closure of the column has a number of disadvantages. First, the plastic grout has a relatively low thermal conductivity. Furthermore, it is difficult to pour into the small gaps and therefore consuming to process. In addition, points after curing they have a different thermal expansion as other components of the battery, causing temperature fluctuations a Cracking in the plastic grout and / or a partial Detaching the plastic grout from a component cause can. Plastic grout is also expensive and fire dangerous. Finally, replacing defective battery cells or disassembly of the battery for disposal after potting of the cell block with Kunststoffvergussmasse not or only with one high effort possible.
