Description
Die Erfindung betrifft eine Batterie mit einem Zellverbund mehrerer Batteriezellen.The invention relates to a battery having a cell assembly of a plurality of 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, a battery for use in motor vehicles, in particular in motor vehicles with a hybrid drive or fuel cell vehicles, a cell block of a plurality of electrically connected in series and / or parallel 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 dissipate the resulting heat loss. For this purpose, liquid cooling or cooling by means of pre-cooled air, which is passed between the cells, is usually 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.When preferred for space reasons liquid cooling a cooling plate with at least one of a cooling liquid, such as a water-glycol mixture, flowed through the cooling channel is arranged on the cell block of the battery. Along the battery cells, the heat is often passed through separate heat-conducting elements, such as heat conduction rods or sheets, to the cooling plate. In this case, the heat-conducting elements are preferably fixedly connected to the cooling plate in order to produce a good thermal contact with this.
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.However, gaps remain between the battery cells and the heat-conducting elements due to manufacturing tolerances, which reduce heat dissipation. Therefore, the gaps are currently closed, for example by plastic grout.
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.However, such a 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 expensive to process. In addition, after curing, it has a different thermal expansion than other components of the battery, as a result of which temperature fluctuations can cause crack formation in the plastic casting compound and / or partial detachment of the plastic casting compound from a component. Plastic grout is also expensive and fire dangerous. Finally, replacement of defective battery cells or disassembly of the battery for disposal after the encapsulation of the cell block with plastic grout is not possible or only with great effort.
In
Der Erfindung liegt die Aufgabe zu Grunde, eine Batterie mit einer gegenüber dem Stand der Technik verbesserten Batteriekühlung anzugeben.The invention is based on the object to provide a battery with a comparison with the prior art improved battery cooling.
Die Aufgabe wird erfindungsgemäß durch eine Anordnung gelöst, welche die in Anspruch 1 angegebenen Merkmale aufweist.The object is achieved by an arrangement having the features specified in
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Die erfindungsgemäße Batterie umfasst einen Zellverbund mehrerer Batteriezellen, eine Kühlplatte zu deren Kühlung und zwischen den Batteriezellen angeordnete Wärmeleitelemente und elastische Wärmekontaktelemente, welche jeweils eine Batteriezelle und ein Wärmeleitelement thermisch miteinander verbinden. Die Wärmeleitelemente sind stoffschlüssig und/oder formschlüssig und/oder kraftschlüssig mit der Kühlplatte verbunden. Die elastischen Wärmekontaktelemente sind stoffschlüssig und/oder formschlüssig und/oder kraftschlüssig an den Wärmeleitelementen oder den Batteriezellen angebracht.The battery according to the invention comprises a cell combination of a plurality of battery cells, a cooling plate for cooling thereof, and heat-conducting elements arranged between the battery cells and elastic thermal contact elements, which each thermally connect a battery cell and a heat-conducting element to one another. The heat-conducting elements are materially and / or positively and / or non-positively connected to the cooling plate. The elastic thermal contact elements are integrally and / or positively and / or non-positively attached to the heat conducting elements or the battery cells.
Die feste Verbindung der Wärmeleitelemente mit der Kühlplatte ermöglicht eine gute Wärmeleitung von den Wärmeleitelementen zu der Kühlplatte. Die thermische Verbindung der Wärmeleitelemente mit den Batteriezellen über die Wärmekontaktelemente ermöglicht eine gute Wärmeleitung von den Batteriezellen zu den Wärmeleitelementen. Dadurch wird vorteilhaft die Wärmeleitung von den Batteriezellen zu der Kühlplatte verbessert und die Lebensdauer der Batterie erhöht.The firm connection of the heat-conducting elements with the cooling plate allows good heat conduction from the heat-conducting elements to the cooling plate. The thermal connection of the heat-conducting elements with the battery cells via the thermal contact elements allows good heat conduction from the battery cells to the heat-conducting elements. Thereby Advantageously, the heat conduction from the battery cells to the cooling plate is improved and the life of the battery is increased.
Aus der festen Verbindung der Wärmeleitelemente mit der Kühlplatte resultieren ferner eine feste Länge des Zellverbundes und feste Positionen der Batteriezellen zwischen den Wärmeleitelementen, wobei die elastischen Wärmekontaktelemente die Batteriezellen gegen benachbarte Wärmeleitelemente pressen und dadurch die Positionen der Batteriezellen fixieren. Dies vereinfacht vorteilhaft die Kontaktierung der Batteriezellen, da hierbei höchstens geringe Positionstoleranzen der Batteriezellen ausgeglichen werden müssen, und erhöht die Stabilität des Zellverbundes.From the fixed connection of the heat-conducting elements with the cooling plate further results in a fixed length of the cell assembly and fixed positions of the battery cells between the heat conducting elements, wherein the elastic thermal contact elements press the battery cells against adjacent heat conducting elements and thereby fix the positions of the battery cells. This advantageously simplifies the contacting of the battery cells, since in this case at most small positional tolerances of the battery cells have to be compensated, and increases the stability of the cell assembly.
Außerdem wird die Montage der Batterie vorteilhaft dahingehend vereinfacht, dass die Batteriezellen in die Zwischenräume zwischen den an der Kühlplatte befestigten Wärmeleitelementen geschoben werden können und keine Spalte zwischen den Batteriezellen und den Wärmeleitelementen mit Wärme leitendem Material wie Vergussmasse ausgefüllt werden müssen. Zugleich wird dadurch auch eine Demontage der Batterie zu deren Entsorgung oder zum Austausch von Batteriezellen vereinfacht bzw. ermöglicht.In addition, the mounting of the battery is advantageously simplified to the effect that the battery cells can be pushed into the spaces between the attached to the cooling plate heat conducting elements and no gaps between the battery cells and the heat conducting need to be filled with heat conductive material such as potting compound. At the same time a disassembly of the battery for their disposal or for the replacement of battery cells is thereby simplified or made possible.
Ferner werden die Anzahl der Bauteile sowie Material- und Herstellungskosten der Batterie reduziert.Furthermore, the number of components as well as material and manufacturing costs of the battery are reduced.
Im Detail sieht eine besonders vorteilhafte Ausgestaltung der Erfindung vor, dass die elastischen Wärmekontaktelemente in die Wärmeleitelemente integriert sind. Eine derartige Ausgestaltung sieht vor, dass die Wärmeleitelemente Wärmeleitbleche und die Wärmekontaktelemente aus den Wärmeleitblechen heraus gebogene Blattfedern sind.In detail, a particularly advantageous embodiment of the invention provides that the elastic thermal contact elements are integrated into the heat-conducting elements. Such an embodiment provides that the heat-conducting elements are heat-conducting sheets and the heat-contact elements are sheet springs bent out of the heat-conducting sheets.
Dadurch werden vorteilhaft die Anzahl der Bauteile sowie Herstellungsaufwand und -kosten der Batterie weiter reduziert.As a result, advantageously the number of components as well as production costs and costs of the battery are further reduced.
Eine weitere Ausgestaltung der Erfindung sieht vor, dass die Wärmekontaktelemente wellenförmige Blattfedern sind, deren jeweilige Wellenberge abwechselnd an einem Wärmeleitelement und an einer Batteriezelle anliegen.A further embodiment of the invention provides that the thermal contact elements are wave-shaped leaf springs whose respective wave crests lie alternately on a heat-conducting element and on a battery cell.
Derart ausgebildete Wärmekontaktelemente haben den Vorteil, dass sie an mehreren Stellen mit den Batteriezellen und Wärmeleitelementen in Wärme leitendem Kontakt stehen und dadurch Wärme gleichmäßig über eine von den wellenförmigen Blattfedern überdeckte Fläche von einer Batteriezelle zu einem Wärmeleitelement übertragen können.Such trained thermal contact elements have the advantage that they are in conductive contact at several points with the battery cells and heat conducting elements in heat and thereby heat evenly over a covered by the wavy leaf springs surface can be transferred from a battery cell to a heat conducting.
Eine vorteilhafte Ausgestaltung der erfindungsgemäßen Batterie sieht vor, dass die Batteriezellen als im Wesentlichen rechteckige Flachzellen und die Wärmeleitelemente als dazu korrespondierende im Wesentlichen rechteckige Wärmeleitbleche ausgebildet sind.An advantageous embodiment of the battery according to the invention provides that the battery cells are designed as substantially rectangular flat cells and the heat-conducting elements as corresponding thereto substantially rectangular Wärmeleitbleche.
Dabei ist jeder Flachzelle ein Wärmeleitblech zugeordnet und eine Flachzelle und das ihr zugeordnete Wärmeleitblech sind parallel zueinander und unmittelbar hintereinander angeordnet.In this case, each flat cell is associated with a heat conducting sheet and a flat cell and its associated heat conducting sheet are arranged parallel to each other and directly behind one another.
Bevorzugt sind die Zellgehäuse der Flachzellen dabei in zwei zueinander parallelen streifenförmigen Randbereichen flacher als in einem dazwischen liegenden Mittelbereich ausgebildet.In this case, the cell housings of the flat cells are preferably formed to be flatter in two strip-shaped edge regions which are parallel to one another than in an intermediate region located therebetween.
Vorzugsweise sind an den beiden streifenförmigen Randbereichen jedes Zellgehäuses auf der dem jeweils zugeordneten Wärmeleitblech zugewandten Seite Wärmekontaktelemente angebracht, welche im entspannten Zustand zum Wärmeleitblech hin über den Mittelbereich des Zellgehäuses hinausragen.Preferably, heat contact elements are mounted on the two strip-shaped edge regions of each cell housing on the side of the respective associated heat conduction facing side, which protrude in the relaxed state to Wärmeleitblech over the central region of the cell housing.
Alternativ sind die Wärmekontaktelemente an den Wärmeleitblechen gegenüber den streifenförmigen Randbereichen der jeweils zugehörigen Flachzelle angebracht.Alternatively, the heat contact elements are attached to the Wärmeleitblechen opposite the strip-shaped edge regions of the respective associated flat cell.
Durch die Anordnung der Blattfedern an den flachen Bereichen der Batteriezellen bzw. an diesen Bereichen gegenüber liegenden Bereichen der Wärmeleitbleche wird vorteilhaft Bauraum eingespart, da die Höhe der Blattfedern der Dicke der des Mittelbereiches der Flachzellen angepasst werden kann.The arrangement of the leaf springs on the flat areas of the battery cells or areas of the heat conducting plates lying opposite to these areas advantageously saves construction space since the height of the leaf springs can be adapted to the thickness of the middle area of the flat cells.
In einer weiteren Ausgestaltung der erfindungsgemäßen Batterie sind die Wärmekontaktelemente als federnde Matten ausgebildet, welche an den Wärmeleitelementen angebracht sind. Dabei bestehen die federnden Matten beispielsweise aus einem Schaummaterial, Gummi oder Fasern und sind vorzugsweise an die Wärmeleitelemente angeklebt.In a further embodiment of the battery according to the invention, the thermal contact elements are designed as resilient mats, which are attached to the heat-conducting elements. The resilient mats consist, for example, of a foam material, rubber or fibers and are preferably glued to the heat-conducting elements.
Derart ausgebildete Wärmekontaktelemente haben den Vorteil, dass sie großflächig und damit gleichmäßig Wärme von den Batteriezellen zu den Wärmeleitelementen übertragen können.Such trained thermal contact elements have the advantage that they can be transferred over a large area and thus evenly heat from the battery cells to the heat conducting elements.
Die Wärmeleitelemente sind bevorzugt an die Kühlplatte angeschweißt, beispielsweise mittels Widerstandspressschweißen, Kondensatorentladungsschweißen oder Laserschweißen.The heat-conducting elements are preferably welded to the cooling plate, for example by means of resistance-pressure welding, capacitor discharge welding or laser welding.
Dadurch wird vorteilhaft eine stoffschlüssige und dadurch gut Wärme leitende Verbindung zwischen den Wärmeleitelementen und der Kühlplatte hergestellt.This advantageously produces a cohesive and thus good heat-conducting connection between the heat-conducting elements and the cooling plate.
