Abstract
Description
Die Erfindung betrifft eine Batterieeinheit einer Kraftfahrzeugbatterie. Des Weiteren betrifft die Erfindung ein Verfahren zur Herstellung einer Batterieeinheit einer Kraftfahrzeugbatterie. The invention relates to a battery unit of a motor vehicle battery. Furthermore, the invention relates to a method for producing a battery unit of a motor vehicle battery.
Aus der
Hiervon ausgehend liegt der vorliegenden Erfindung die Aufgabe zu Grunde eine neuartige Batterieeinheit einer Kraftfahrzeugbatterie sowie ein Verfahren zur Herstellung derselben zu schaffen. On this basis, the present invention, the object of a novel battery unit of a motor vehicle battery and a method for producing the same to create.
Diese Aufgabe wird durch eine Batterieeinheit einer Kraftfahrzeugbatterie gemäß Patentanspruch 1 gelöst. Erfindungsgemäß sind jeweils unmittelbar benachbarte Kühlelemente über jeweils mindestens ein elastisches und komprimierbares Verbindungselement unter Ausbildung von Aufnahmebereichen für die Batteriezellen miteinander verbunden. This object is achieved by a battery unit of a motor vehicle battery according to claim 1. According to the invention, immediately adjacent cooling elements are connected to one another via in each case at least one elastic and compressible connecting element, forming receiving areas for the battery cells.
Mit der hier vorliegenden Erfindung wird vorgeschlagen, unmittelbar benachbarte Kühlelemente über jeweils mindestens ein elastisches und komprimierbares und damit flexibles Verbindungselement miteinander zu verbinden, nämlich unter Ausbildung von Aufnahmebereichen für die Batteriezellen. Eine solche Ausbildung der Batterieeinheit erlaubt eine einfache Aufnahme der Batteriezellen zwischen den Kühlelementen. Bedingt durch die Verwendung elastischer Verbindungselemente können die als Kühlmodul zusammengefassten Kühlelemente bei der Aufnahme bzw. Anordnung der Batteriezellen in den von den Kühlelementen begrenzten Aufnahmebereichen in gewissem Umfang relativ zueinander bewegt werden. With the present invention, it is proposed to connect directly adjacent cooling elements via in each case at least one elastic and compressible and thus flexible connecting element with each other, namely to form receiving areas for the battery cells. Such a design of the battery unit allows easy recording of the battery cells between the cooling elements. Due to the use of elastic connecting elements, the cooling elements combined as a cooling module can be moved relative to one another during the reception or arrangement of the battery cells in the receiving areas delimited by the cooling elements to a certain extent.
Die Komprimierbarkeit der Verbindungselemente erlaubt ein Verpressen bzw. Verspannen der Batterieeinheit und damit eine Fixierung der Batteriezellen in den von den Kühlelementen begrenzten Aufnahmebereichen der Batterieeinheit zum Beispiel bei der Montage der Batterieeinheit in einem Gehäuse der Kraftfahrzeugbatterie. The compressibility of the connecting elements allows a pressing or clamping of the battery unit and thus a fixation of the battery cells in the limited by the cooling elements receiving areas of the battery unit, for example, during assembly of the battery unit in a housing of the motor vehicle battery.
Vorzugsweise ist jedes elastische und komprimierbare Verbindungselement aus einem elektrisch isolierenden Schaumwerkstoff gefertigt, welches mit den jeweiligen Kühlelementen verklebt ist. Die Verwendung eines elektrisch isolierenden Schaumwerkstoffs zur Bereitstellung der elastischen und komprimierbaren Verbindungselemente ist besonders bevorzugt. Hiermit können elektrische Spannungen zwischen den üblicherweise aus einem metallischen Werkstoff gefertigten Kühlelementen durch eventuell fehlerhaft auftretende elektrische Kriechströme verhindert werden. Ferner kann der Schaumwerkstoff der Verbindungselemente einfach mit den Kühlelementen verklebt werden. Preferably, each elastic and compressible connecting element is made of an electrically insulating foam material, which is glued to the respective cooling elements. The use of an electrically insulating foam material to provide the elastic and compressible connecting elements is particularly preferred. This electrical voltages between the usually made of a metallic material cooling elements can be prevented by possibly erroneous electrical leakage currents. Furthermore, the foam material of the connecting elements can be easily glued to the cooling elements.
Nach einer vorteilhaften Weiterbildung der Erfindung ist jedes elastische und komprimierbare Verbindungselement als U-Profil aus einem Ethylen-Propylen-Dien-Kautschuk-Schaum ausgeführt, wobei jedes Verbindungselement zwei unmittelbar benachbarte Kühlelemente an drei Seiten miteinander verbindet. Die Verwendung eines EPDM-Schaums für die Verbindungselemente ist besonders bevorzugt. According to an advantageous embodiment of the invention, each elastic and compressible connecting element is designed as a U-profile of an ethylene-propylene-diene rubber foam, wherein each connecting element connects two directly adjacent cooling elements on three sides. The use of an EPDM foam for the fasteners is particularly preferred.
Das erfindungsgemäße Verfahren zur Herstellung einer Batterieeinheit einer Kraftfahrzeugbatterie ist in Patentanspruch 10 definiert. The inventive method for producing a battery unit of a motor vehicle battery is defined in
