Description
Die Erfindung betrifft ein Batteriegehäuse, umfassend einen Bodenabschnitt sowie einen mit diesem verbundenen Unterfahrschutz.The invention relates to a battery housing comprising a base section and an underride guard connected to it.
Ein solches Batteriegehäuse wird beispielsweise zur Herstellung eines Energiespeichers für ein Kraftfahrzeug verwendet. Es dient der Aufnahme einzelner Speichermodule. Üblicherweise besteht es aus einer Batteriewanne, die den Bodenabschnitt sowie die Seitenwände bildet, sowie einem damit verbundenen Deckel. Zwischen Bodenabschnitt und Deckel sind üblicherweise ein oder mehrere Versteifungselemente in Form von Quer- oder Längsstegen vorgesehen, über die eine entsprechende Unterteilung des Innenraums zur Aufnahme der einzelnen Speichermodule möglich ist. Zumeist ist auch ein Unterfahrschutz vorgesehen, der unterhalb des Bodenabschnitts respektive unterhalb der Batteriewanne angeordnet wird und dazu dient, die Batteriewanne respektive das Batteriegehäuse bei einem unterseitigen Auffahren oder vor anderen Beschädigungen zu schützen. Dabei ist üblicherweise der Unterfahrschutz über mehrere Abstützelemente respektive Verstärkungsprofile am Batteriegehäuse respektive dem Bodenabschnitt abgestützt. Hierüber wird eine mechanisch feste Verbindung respektive Abstützung sichergestellt. Problematisch hierbei ist jedoch, dass, nachdem der Bodenabschnitt respektive die Batteriewanne wie auch der Unterfahrschutz und das oder die Abstützelemente respektive Verstärkungsprofile aus Metall sind, eine wärmeleitfähige Verbindung gegeben ist. Dies kann dazu führen, dass über den Unterfahrschutz, der quasi als Heiz- oder Kühlplatte wirkt, ein erhöhter Wärme- oder Kälteeintrag in das Innere des Batteriegehäuses, mithin also in den Speicherzellenbereich gegeben ist, was für die Sicherstellung einer optimalen Batteriebetriebstemperatur zu einem erhöhten Kühl- oder Heizbedarf bzw. einer reduzierten Reichweite führt.Such a battery housing is used, for example, to produce an energy store for a motor vehicle. It is used to hold individual memory modules. It usually consists of a battery tray, which forms the bottom section and the side walls, and a cover connected to it. One or more stiffening elements in the form of transverse or longitudinal webs are usually provided between the base section and the cover, via which a corresponding subdivision of the interior space for accommodating the individual memory modules is possible. In most cases, an underride guard is also provided, which is arranged below the bottom section or below the battery tray and serves to protect the battery tray or the battery housing when it is opened from underneath or against other damage. The underride protection is usually supported on the battery housing or the base section via a plurality of support elements or reinforcement profiles. This ensures a mechanically firm connection or support. The problem here, however, is that after the base section or the battery tray as well as the underrun protection and the support element or reinforcement profiles are made of metal, there is a thermally conductive connection. This can lead to increased heat or cold being introduced into the interior of the battery housing, i.e. into the storage cell area, via the underride protection, which acts as a heating or cooling plate, which ensures an optimal battery operating temperature and increased cooling - or heating requirements or a reduced range.
Der Erfindung liegt damit das Problem zugrunde, ein demgegenüber verbessertes Batteriegehäuse anzugeben.The invention is therefore based on the problem of specifying an improved battery housing.
Zur Lösung dieses Problems ist bei einem Batteriegehäuse der eingangs genannten Art erfindungsgemäß vorgesehen, dass der Unterfahrschutz und der Bodenabschnitt über wenigstens einen Abstandshalter voneinander beabstandet sind, der eine niedrigere Wärmeleitfähigkeit als der Bodenabschnitt und der Unterfahrschutz aufweist.To solve this problem, it is provided according to the invention in a battery housing of the type mentioned at the outset that the underride guard and the bottom section are spaced apart from one another by at least one spacer which has a lower thermal conductivity than the bottom section and the underride guard.
Erfindungsgemäß wird zwischen Bodenabschnitt respektive Batteriewanne und Unterfahrschutz ein oder bevorzugt mehrere Abstandshalter gesetzt, die aus einem hinreichend thermisch isolierenden Material bestehen, mithin also eine deutlich niedrigere Wärmeleitfähigkeit als der Bodenabschnitt und der Unterfahrschutz aufweisen. Es wird also eine definierte thermische Isolationsebene eingezogen, um den Wärmetransport vom Unterfahrschutz zum Bodenabschnitt und zu reduzieren. Das heißt, dass soweit möglich keine Verbindungen oder Kopplungen zwischen dem Unterfahrschutz und dem Bodenabschnitt gegeben sind, die eine hohe Wärmeübertragung erlauben, oder es ist zumindest die Anzahl derartiger Verbindungen durch das Zwischenschalten entsprechender Abstandshalter deutlich reduziert im Vergleich zu bisher bekannten Batteriegehäusen. Bevorzugt werden diese Abstandshalter in Bereichen eingesetzt, an denen der Unterfahrschutz zum Bodenabschnitt lediglich mechanisch abgestützt ist, dort also nicht über ein Befestigungselement wie eine Schraubenverbindung oder dergleichen feste verschraubt ist. Denn im Verschraubungsbereich ist die Integration einer Isolationsebene denkbar, aber nicht immer möglich, wohl aber in den reinen Abstützbereichen, wo lediglich eine mechanische Abstützung, aber keine mechanische Verbindung gegeben ist.According to the invention, one or preferably several spacers are placed between the floor section or battery trough and the underride guard, which are made of a sufficiently thermally insulating material, and thus therefore have a significantly lower thermal conductivity than the bottom section and the underride guard. A defined thermal insulation level is therefore drawn in to reduce the heat transfer from the underrun protection to the floor section and. This means that as far as possible there are no connections or couplings between the underride protection and the floor section that allow high heat transfer, or at least the number of such connections is significantly reduced by the interposition of corresponding spacers in comparison to previously known battery housings. These spacers are preferably used in areas where the underrun protection is only mechanically supported to the floor section, that is to say there is not firmly screwed there via a fastening element such as a screw connection or the like. This is because the integration of an insulation level is conceivable in the screwing area, but not always possible, but in the pure support areas where there is only mechanical support but no mechanical connection.
Wie beschrieben ist der Bodenabschnitt und der Unterfahrschutz bevorzugt über mehrere zwischen dem Bodenabschnitt und dem Unterfahrschutz verteilt angeordnete Abstandshalter voneinander beabstandet, wobei wie ausgeführt diese bevorzugt im Bereich der reinen Abstützpositionen vorgesehen werden, von denen es, gesehen auf die Fläche, eine beachtliche Anzahl gibt. Der oder jeder Abstandshalter besteht bevorzugt aus einem Kunststoff, wobei ein solches Kunststoffmaterial gewählt wird, das einerseits gute thermische Isolationseigenschaften aufweist, gleichzeitig aber auch eine ausreichende Festigkeit besitzt, so dass es auch die mechanische Abstützfunktion, die an dieser Abstützposition gefordert ist, erfüllt.As described, the bottom section and the underride guard are preferably spaced apart from one another by a plurality of spacers arranged between the bottom section and the underride guard, wherein, as stated, these are preferably provided in the area of the pure support positions, of which there is a considerable number, as seen on the surface. The or each spacer is preferably made of a plastic, such a plastic material being selected which on the one hand has good thermal insulation properties, but at the same time also has sufficient strength so that it also fulfills the mechanical support function that is required at this support position.
Die Geometrie des oder jedes Abstandshalters kann quasi beliebig sein, je nachdem, wie die bauliche Situation ist. Es kann sich um einen quaderförmigen Abstandshalter handeln, wobei diese Form beispielsweise gewählt wird, wenn sich der oder jeder Abstandshalter direkt zwischen dem Bodenabschnitt und dem Unterfahrschutz erstreckt, mithin also der Abstandshalter quasi eine Doppelfunktion erfüllt, nämlich einerseits die des Abstützelements respektive Verstärkungsprofils, andererseits die des thermischen Isolationsbauteils. Alternativ kann der Abstandshalter auch scheibenförmig, also rund, oder plattenförmig, beispielsweise rechteckig oder mehreckig etc. ausgeführt sein. Eine solche flache Form wird bevorzugt dann verwendet, wenn am Unterfahrschutz oder am Bodenabschnitt ein oder mehrere Abstützelemente vorgesehen sind, wobei der oder jeweils ein Abstandshalter zwischen einem Abstützelement und dem Bodenabschnitt oder dem Unterfahrschutz angeordnet ist. In diesem Fall wird folglich der flache Abstandshalter quasi sandwichartig zwischen dem Abstützelement und dem Bodenabschnitt und dem Unterfahrschutz positioniert.The geometry of the or each spacer can be virtually any, depending on the structural situation. It can be a cuboid spacer, this shape being selected, for example, if the or each spacer extends directly between the base section and the underrun protection, thus the spacer basically fulfills a double function, namely that of the support element or reinforcement profile, on the other hand, that of the thermal insulation component. Alternatively, the spacer can also be disc-shaped, that is to say round, or plate-shaped, for example rectangular or polygonal, etc. Such a flat shape is preferably used when one or more support elements are provided on the underride guard or on the floor section, the or each spacer being arranged between a support element and the bottom section or the underride guard. In this case, the flat spacer is thus sandwiched between the support element and the bottom portion and the underrun protection positioned.
Kommt ein solches Abstützelement oder kommen mehrere solcher Abstützelemente zum Einsatz, so weist das oder jedes Abstützelement zweckmäßigerweise einen gewinkelten oder gebogenen Querschnitt mit seitlichen Anlageabschnitten am Unterfahrschutz oder am Bodenabschnitt und einem mittigen flächigen Anlageabschnitt am Bodenabschnitt oder am Unterfahrschutz auf, wobei der Abstandshalter am mittigen flächigen Anlageabschnitt angeordnet ist. Dieser mittige flächige Anlageabschnitt bietet eine hinreichend große Auflagefläche für den Abstandshalter, der an der anderen Seite an dem ebenfalls in diesem Bereich flächigen Bodenabschnitt anliegt, so dass eine großflächige Anlage gegeben ist, was insbesondere aus mechanischen Gründen zweckmäßig ist.If such a support element or several such support elements are used, the or each support element expediently has an angled or curved cross section with lateral contact sections on the underrun protection or on the floor section and a central flat contact section on the bottom section or on the underride protection, the spacer on the central flat section Plant section is arranged. This central, flat contact section offers a sufficiently large contact surface for the spacer, which lies on the other side against the bottom section, which is also flat in this area, so that there is a large-scale contact, which is particularly expedient for mechanical reasons.
Der Abstandshalter kann am Bodenabschnitt, am Unterfahrschutz oder am Abschnittselement über ein Befestigungsmittel befestigt sein, so dass eine einfache Montage möglich ist. Bevorzugt ist der Abstandshalter angeklebt.The spacer can be fastened to the floor section, to the underrun protection or to the section element by means of a fastening means, so that simple assembly is possible. The spacer is preferably glued on.
Weiterhin kann vorgesehen sein, dass der Abstandshalter zwischen einer Vertiefung des Bodenabschnitts, in der ein Fuß eines den Bodenabschnitt und einen Deckelabschnitt stützenden Abstützelements aufgenommen ist, und dem Unterfahrschutz oder dem Abstützelement angeordnet ist. Diese Vertiefung des Bodenabschnitts dient dazu, den flachen, quasi platten- oder stegförmigen Fuß eines solchen Stützelements aufzunehmen, so dass die Oberseite dieses ebenen Fußes bündig mit der Oberseite respektive Ebene der Innenfläche des Bodenabschnitts ist. Hierüber wird sichergestellt, dass der Abstand eines aufgenommenen Energiespeichers zum Bodenabschnitt nahezu an allen Stellen gleich ist, sich also ein gleicher Spalt zwischen Energiespeicher und Bodenabschnitt einstellt, was für eine gleichmäßige Kühlung besonders zweckmäßig ist. Denn der Energiespeicher ist nahezu an allen Positionen gleichweit entweder vom Bodenabschnitt oder dann von der Oberseite des jeweiligen Fußes beabstandet. Sind nun derartige Vertiefungen vorgesehen, so ist es zweckmäßig, wenn einerseits die Abstützelemente in diesen Bereichen angeordnet sind, ebenso die Abstandshalter, mithin also die Abstützung und Isolierung zu diesem vertieften Bodenabschnittsbereich erfolgt.Furthermore, it can be provided that the spacer is arranged between a recess in the base section, in which a foot of a support element supporting the base section and a cover section is accommodated, and the underride protection or the support element. This depression of the base section serves to receive the flat, quasi-plate-like or web-shaped base of such a support element, so that the top side of this flat base is flush with the top side or plane of the inner surface of the base portion. This ensures that the distance of an absorbed energy store to the base section is almost the same at all points, that is, there is an equal gap between the energy store and the base section, which is particularly expedient for uniform cooling. This is because the energy store is equally spaced at almost all positions either from the bottom section or from the top of the respective foot. If such depressions are now provided, it is expedient if, on the one hand, the support elements are arranged in these areas, and also the spacers, and therefore the support and insulation to this recessed floor section area.
