Description
Stand der TechnikState of the art
Die Erfindung geht aus von einer Batterie nach der Gattung des unabhängigen Anspruchs. Es ist schon ein aus der
Zur Erwärmung von Körpern oder Medien, wie beispielsweise Gase oder Flüssigkeiten, an sich können grundsätzlich unterschiedlichste elektrische Heizelemente eingesetzt werden, wie zum Beispiel keramische PTC-Heizelemente, metallische Widerstandsheizungen oder auch Widerstandsheizungen auf Basis von elektrisch leitfähigen Kunststoffen, wie sie zum Beispiel aus der
Auf Basis von Elastomeren lassen sich ebenfalls Heizelemente herstellen, wie aus der
Auch aus der
Aus der nachveröffentlichten deutschen Patentanmeldung mit dem Aktenzeichen 10 2022 210 476.5 ist es bekannt, eine Heizeinrichtung mit einem in einem Gehäuse eingelassenen Heizelement, welches aus mindestens einer Elastomerformmasse unter Einschluss elektrisch leitfähiger Partikel gefertigt ist, mit einer Stützstruktur auf einer Seite des Heizelements zu versehen.From the subsequently published German patent application with the file number 10 2022 210 476.5, it is known to provide a heating device with a heating element embedded in a housing, which is made of at least one elastomer molding compound including electrically conductive particles, with a support structure on one side of the heating element.
Offenbarung der ErfindungDisclosure of the invention
Die erfindungsgemäße Batterie mit den kennzeichnenden Merkmalen des unabhängigen Anspruchs hat demgegenüber den Vorteil einer homogenen Verteilbarkeit der Wärmeerzeugung innerhalb der Batterie. Des Weiteren von Vorteil ist, daß sich eine elastische Heizmatte bzw. elastische Heizmatten an die Oberfläche einzelner Batteriezellen gut anpassen können, wodurch ein optimaler Wärmeübertrag erfolgen kann.The battery according to the invention with the characterizing features of the independent claim has the advantage of homogeneous distribution of the heat generation within the battery. Another advantage is that an elastic heating mat or elastic heating mats can adapt well to the surface of individual battery cells, which allows optimal heat transfer.
Durch die in den abhängigen Ansprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im unabhängigen Anspruch angegebenen Batterie möglich.The measures listed in the dependent claims enable advantageous further developments and improvements of the battery specified in the independent claim.
Besonders vorteilhaft ist es, Heizeinrichtungen mit Mitteln zur Ausdehnungskompensation zwischen Batteriezellen der Batterie anzuordnen, beispielsweise in Form einer elastischen Struktur, welche einen freien Raum zur Kompression bietet und ein Anschwellen der Batteriezellen während eines Lade- bzw. Entladebetriebs kompensieren kann. Darüber hinaus können thermische Ausdehnungen auch der heizenden Elastomerschicht selbst und örtliche Verformungen kompensiert bzw. die äußeren Maße des Batteriezellenstapels, also der Batterie, konstant gehalten werden.It is particularly advantageous to arrange heating devices with means for expansion compensation between battery cells of the battery, for example in the form of an elastic structure which offers free space for compression and can compensate for swelling of the battery cells during charging or discharging. In addition, thermal expansion of the heating elastomer layer itself and local deformations can be compensated or the external dimensions of the battery cell stack, i.e. the battery, can be kept constant.

Ausführungsformen der ErfindungEmbodiments of the invention
Alternativ kann auch nur eine Heizmatte nur pro zwei Batteriezellen vorgesehen werden derart, daß jede aneinandergereihte Batteriezelle auf der einen Seite flächig mit einer Heizeinrichtung und auf der anderen Seite mit einer weiteren Batteriezelle - ohne dazwischenliegende Heizeinrichtung - in mechanischem Kontakt steht. Eine elastische Heizmatte kann sich an die Oberfläche der Batteriezellen anpassen, dadurch kann ein optimaler Wärmeübertrag erfolgen. Als Heizstromversorgung kann direkt die von der Batterie bereitgestellte elektrische Batteriespannung bzw. die Bordnetzspannung des Kraftfahrzeugs eingesetzt werden.Alternatively, only one heating mat can be provided for every two battery cells, so that each battery cell lined up next to one another is in mechanical contact with a heating device on one side and with another battery cell on the other side - without a heating device in between. An elastic heating mat can adapt to the surface of the battery cells, which allows for optimal heat transfer. The electrical battery voltage provided by the battery or the vehicle's on-board voltage can be used directly as the heating power supply.
Eine Heizeinrichtung bzw. Heizmatte bzw. eine elektrisch leitfähige Elastomerschicht zwischen zwei Batteriezellen kann als Mittel zur Ausdehnungskompensation auch eine Stützstruktur wie in der nachveröffentlichten deutschen Patentanmeldung mit dem Aktenzeichen 10 2022 210 476.5 beschrieben aufweisen, deren Offenbarung hiermit in die vorliegende Anmeldung einbezogen ist.A heating device or heating mat or an electrically conductive elastomer layer between two battery cells can also have a support structure as described in the subsequently published German patent application with the file number 10 2022 210 476.5 as a means of compensating for expansion, the disclosure of which is hereby incorporated into the present application.
Eine Heizeinrichtung bzw. Heizmatte bzw. eine elektrisch leitfähige Elastomerschicht zwischen zwei Batteriezellen kann auch zwei separate Elastomerteilschichten aufweisen, welche wechselseitig aufeinandergelegt werden und welche jeweils eine zur anderen Elastomerschicht hin orientierte Struktur, jedoch zur jeweils benachbarten Batteriezelle eine glatte Fläche haben. So ist bei dieser Variante einerseits durch die gegenüberliegenden Strukturen ein Mittel zur Ausdehnungskompensation bereitgestellt und andererseits ein optimaler Wärmeübergang zu den benachbarten Batteriezellen gewährleistet.A heating device or heating mat or an electrically conductive elastomer layer between two battery cells can also have two separate elastomer sub-layers, which are placed alternately on top of each other and which each have a structure oriented towards the other elastomer layer, but a smooth surface towards the adjacent battery cell. In this variant, the opposing structures provide a means of compensating for expansion on the one hand, and on the other hand, optimal heat transfer to the adjacent battery cells is ensured.
Eine Heizeinrichtung bzw. Heizmatte bzw. eine elektrisch leitfähige Elastomerschicht zwischen zwei Batteriezellen kann auch eine geschäumte Matte aus einem elektrisch leitfähigem Elastomer sein bzw. aufweisen. Eine solche Heizmatte kann chemisch oder physikalisch geschäumt werden. Die Wandungen werden durch die schnelle Erkaltung dicht und zur Mitte der Matte hin bildet sich zunehmend eine Schaumstruktur aus, welche ein Mittel zur Ausdehnungskompensation darstellt.A heating device or heating mat or an electrically conductive elastomer layer between two battery cells can also be or have a foamed mat made of an electrically conductive elastomer. Such a heating mat can be foamed chemically or physically. The walls become dense due to the rapid cooling and a foam structure increasingly forms towards the middle of the mat, which represents a means of compensating for expansion.
