Abstract
Description
Die vorliegende Erfindung betrifft eine Batterie mit einer Batteriezelle, einem thermischen Element und einer Verbundstruktur, welche eine erste und eine zweite elektrisch isolierende Komponente umfasst, wobei die erste Komponente nicht elastisch ist, während die zweite Komponente thermisch leitfähig und in der Verbundstruktur so angeordnet ist, dass sie einen thermischen Kontakt zwischen der Batteriezelle und dem thermischen Element herstellt.The present invention relates to a battery having a battery cell, a thermal element and a composite structure comprising a first and a second electrically insulating component, wherein the first component is non-elastic, while the second component is thermally conductive and arranged in the composite structure, in that it establishes a thermal contact between the battery cell and the thermal element.
Stand der TechnikState of the art
Um die Sicherheit von Batterien beziehungsweise Batteriepacks gewährleisten zu können, müssen insbesondere dann, wenn diese Batterien beziehungsweise Batteriepacks Lithium-Ionen-Batteriezellen aufweisen, zwei wesentliche Voraussetzungen erfüllt sein. Zum einen ist es notwendig, dass die Batteriezellen dieser Batteriepacks innerhalb eines vorgegebenen Temperaturbereichs betrieben werden, zum anderen müssen die Batteriezellen des Batteriepacks gegenüber den verbleibenden Bauteilen des jeweiligen Batteriepacks elektrisch isoliert sein. In order to be able to ensure the safety of batteries or battery packs, two essential prerequisites must be met, in particular if these batteries or battery packs have lithium-ion battery cells. On the one hand, it is necessary that the battery cells of these battery packs are operated within a predetermined temperature range, on the other hand, the battery cells of the battery pack must be electrically insulated from the remaining components of the respective battery pack.
Aus diesem Grund werden im Stand der Technik innerhalb von Batteriepacks sogenannte Wärmesenken beziehungsweise Wärmequellen verbaut, durch welche die Temperatureigenschaften des Batteriepacks beeinflusst werden. Dabei sind dem Stand der Technik verschiedene Varianten für die Realisation von Wärmesenken beziehungsweise Wärmequellen bekannt. Beispielsweise existieren im Stand der Technik Batteriepacks, welche fluiddurchströmte Platten aufweisen, welche mit den Batteriezellen innerhalb der Batteriepacks in thermischem Kontakt stehen, also als Kühl- oder Heizplatte fungieren. Dabei müssen Spalte, welche sich aufgrund von Unebenheiten an den Kontaktflächen zwischen den fluiddurchströmten Platten sowie den Batteriezellen bilden, vermieden werden, damit ein guter thermischer Kontakt ermöglicht werden kann. Ferner muss sichergestellt werden, dass die Batteriezellen des Batteriepacks elektrisch von der fluiddurchströmten Platte isoliert sind. For this reason, so-called heat sinks or heat sources are installed in the prior art within battery packs, which influence the temperature characteristics of the battery pack. In this case, the prior art, various variants for the realization of heat sinks or heat sources are known. For example, in the prior art battery packs which have fluid-flow plates which are in thermal contact with the battery cells within the battery pack, so act as a cooling or heating plate. In this case, gaps which form due to unevenness at the contact surfaces between the fluid-flow plates and the battery cells must be avoided, so that a good thermal contact can be made possible. Furthermore, it must be ensured that the battery cells of the battery pack are electrically isolated from the fluid-flow plate.

Offenbarung der ErfindungDisclosure of the invention
Erfindungsgemäß wird eine Batterie zur Verfügung gestellt, welche eine Batteriezelle, ein thermisches Element und eine Verbundstruktur für die Kontaktierung der Batteriezelle mit dem thermischen Element umfasst. Die Verbundstruktur ist an einer Kontaktstelle direkt zwischen der Batteriezelle und dem thermischen Element angeordnet. Erfindungsgemäß umfasst die Verbundstruktur eine erste Komponente, die elektrisch isolierend und nicht elastisch ist, und eine zweite Komponente, die elektrisch isolierend und thermisch leitfähig ist. Die zweite Komponente ist so in der Verbundstruktur angeordnet, dass sie einen thermischen Kontakt zwischen der Batteriezelle und dem thermischen Element herstellt.According to the invention, a battery is provided which comprises a battery cell, a thermal element and a composite structure for contacting the battery cell with the thermal element. The composite structure is disposed at a contact point directly between the battery cell and the thermal element. According to the invention, the composite structure comprises a first component, which is electrically insulating and non-elastic, and a second component, which is electrically insulating and thermally conductive. The second component is arranged in the composite structure so as to establish thermal contact between the battery cell and the thermal element.
In der erfindungsgemäßen Batterie ist eine gegenüber dem Stand der Technik verbesserte thermische Kontaktierung der Batteriezellen an ein thermisches Element, beispielsweise eine Kühlplatte oder eine Heizplatte, durch die Verwendung einer Verbundstruktur realisiert. Durch die erste, nicht elastische Komponente der Verbundstruktur ist sichergestellt, dass der Abstand zwischen der Oberfläche der Batteriezelle und dem thermischen Element nicht kleiner wird, als der durch die Abmessungen beziehungsweise die Höhe der ersten Komponente selbst vorgegebene Abstand. Durch die zweite Komponente ist eine gute thermische Verbindung zwischen der Oberfläche der Batteriezelle mit der Oberfläche des thermischen Elements realisiert. In the battery according to the invention an improved over the prior art thermal contacting of the battery cells to a thermal element, such as a cooling plate or a hot plate, realized by the use of a composite structure. The first, non-elastic component of the composite structure ensures that the distance between the surface of the battery cell and the thermal element does not become smaller than the distance predetermined by the dimensions or the height of the first component itself. The second component realizes a good thermal connection between the surface of the battery cell and the surface of the thermal element.
Bevorzugt ist die zweite Komponente in die erste Komponente eingelassen. Durch eine derartige Ausführungsform sind die erste und die zweite Komponente platzsparend miteinander verbunden beziehungsweise kombiniert. Preferably, the second component is embedded in the first component. By such an embodiment, the first and the second component are space-saving connected or combined.
Vorzugsweise ist die erste Komponente als Platte mit Ausnehmungen ausgeführt, wobei die Ausnehmungen durch die zweite Komponente ausgefüllt sind. Bei einer derartigen Ausführungsform der Verbundstruktur kann selbige sehr gut auch zwischen beispielsweise einer Vielzahl von Batteriezellen und zum Beispiel einer Heizplatte oder einer Kühlplatte angeordnet werden. Auch die oben beschriebenen Funktionen der ersten und zweiten Komponente können bei einer derartigen Ausführung der Verbundstruktur von selbigen besonders gut erfüllt werden.Preferably, the first component is designed as a plate with recesses, wherein the recesses are filled by the second component. In such an embodiment of the composite structure, the same can be arranged very well, for example, between a plurality of battery cells and, for example, a heating plate or a cooling plate. Also, the above-described functions of the first and second components can be fulfilled particularly well in such an embodiment of the composite structure of the same.
In einer bevorzugten Ausführungsform ist die erste Komponente der Verbundstruktur ein Kunststoff. Kunststoffe zählen zu den leichtesten Werkstoffen überhaupt und sind zudem besonders kostengünstig. Ferner sind Kunststoffe gute Isolatoren für den elektrischen Strom und lassen sich leicht und kostengünstig formen. In a preferred embodiment, the first component of the composite structure is a plastic. Plastics are among the lightest materials ever and are also particularly cost-effective. Furthermore, plastics are good insulators for the electric current and can be easily and inexpensively molded.
Bevorzugt ist das Material für die zweite Komponente ausgewählt aus einer Gruppe, umfassend Wärmeleitpasten, mit wärmeleitenden Zusätzen optimierte Gele und Vergussmassen. Bei Wärmeleitpasten handelt es sich um thermisch hoch leitfähige Materialien, welche sich im Gegensatz zu beispielsweise Wärmeleitpads unter anderem besonders gut dazu eignen, bestehende Hohlräume oder Ausnehmungen, beispielsweise innerhalb der wie oben ausgeführten Verbundstruktur, zu befüllen. Vergussmassen weisen ein sehr gutes Fließverhalten auf und können auf verschiedene Weisen ausgehärtet werden. The material for the second component is preferably selected from a group comprising thermal pastes, gels and casting compounds optimized with heat-conducting additives. Thermally conductive pastes are highly thermally conductive materials which, in contrast to, for example, heat-conducting pads, are particularly suitable, inter alia, for filling existing cavities or recesses, for example within the composite structure as described above. Potting compounds have a very good flow behavior and can be cured in various ways.
In einer bevorzugten Ausführungsform ist die Verbundstruktur auf der mit der Batteriezelle in Kontakt stehenden Seite zumindest teilweise mit der zweiten Komponente überzogen.In a preferred embodiment, the composite structure on the side in contact with the battery cell is at least partially coated with the second component.
Bevorzugt ist die Batterie als eine Lithium-Ionen-Batterie ausgeführt. Vorteile solcher Batterien sind unter anderem in ihrer vergleichsweise hohen Energiedichte sowie ihrer großen thermischen Stabilität gegeben. Ein weiterer Vorteil von Lithium-Ionen-Batterien ist, dass diese keinem Memory Effekt unterliegen.Preferably, the battery is designed as a lithium-ion battery. Advantages of such batteries include their comparatively high energy density and their high thermal stability. Another advantage of lithium-ion batteries is that they are not subject to memory effect.
Ferner wird ein Kraftfahrzeug mit einer erfindungsgemäßen Batterie bereitgestellt, wobei die Batterie mit einem Antriebssystem des Kraftfahrzeugs verbunden ist.Furthermore, a motor vehicle is provided with a battery according to the invention, wherein the battery is connected to a drive system of the motor vehicle.
