HOCHVOLTBATTERIE MIT VERBINDEREINHEIT UND VERBINDEREINHEIT FÜR EINE SOLCHE HIGH-VOLTAGE BATTERY WITH CONNECTOR UNIT AND CONNECTOR UNIT FOR SUCH A
Die Erfindung betrifft eine Hochvoltbatterie, die aus einer Anzahl in Reihen angeordneten zylindrischen Zellen, einer Tragstruktur für die Zellen und einer Deckplatte besteht, an welcher Deckplatte Hochstrom- Verbinder für die einzelnen Zellen und eine Zeilüberwachungseinheit angebracht sind. Dabei sind unter Batterie elektrische Speicher aller Art zu verstehen: chemische, kapazitive, etc.The invention relates to a high-voltage battery, which consists of a number of arranged in rows of cylindrical cells, a support structure for the cells and a cover plate on which cover plate high-current connector for the individual cells and a cell monitoring unit are mounted. Under battery electric storage of all kinds are to be understood: chemical, capacitive, etc.
Derartige Batterien werden neuerdings für den Antrieb von Kraftfahrzeugen in verschiedenen Anordnungen eingesetzt. Sie können die dafür erforderlichen hohen Ströme liefern, müssen dafür aber nicht nur gekühlt, sondern auch laufend überwacht werden.Such batteries are recently used for driving motor vehicles in various arrangements. They can supply the required high currents, but not only have to be cooled, but also constantly monitored.
Bei bekannten gattungsgemäßen Batterien sind die Hochstrom- Verbinder der einzelnen Zellen und zu den externen Anschlüssen in passende Ausnehmungen der Deckplatte eingesetzte Leiter aus Kupfer. Die Zellüberwachungsein- heit ist eine separate, über der Deckplatte angebrachte Einheit, die über ein- zelne Leiter, Drähte oder Lamellen aus Kupferblech, oft auch über Steckverbinder an die Pole der einzelnen Zellen angeschlossen ist. Diese Verbindungen sind Korrosion und Erschütterungen ausgesetzt, sodass Funktionsstörungen auftreten.In known generic batteries, the high-current connectors of the individual cells and to the external terminals inserted into matching recesses of the cover plate conductor made of copper. The cell monitoring unit is a separate unit mounted above the cover plate, individual conductors, wires or lamellae made of copper sheet, often also connected via plug connectors to the poles of the individual cells. These connections are subject to corrosion and vibration, causing malfunction.
Der Fertigungs- und Montageaufwand für eine derartige Batterie ist sehr groß, wegen der großen Anzahl an Bauteilen und der komplizierten Form der Deckplatte (siehe etwa die EP 1109237 Bl) und weil die einzelnen Leiter einzeln in die Deckplatte eingesetzt und in ihr befestigt beziehungsweise miteinander verbunden werden müssen. Dazu kommt, dass für verschiedene (fahrzeugspe- zifische) Ausführungen der Batterie verschieden angeordnete Zellverbinder und auch verschiedene Deckplatten bereitstehen müssen.The manufacturing and assembly costs for such a battery is very large, because of the large number of components and the complicated shape of the cover plate (see, for example, EP 1109237 Bl) and because the individual conductors individually inserted into the cover plate and fixed in it or connected to each other Need to become. In addition, for different (vehicle-specific) versions of the battery differently arranged cell connectors and also different cover plates must be available.
Aus der EP 1363483 A2 ist ein Verfahren zur Herstellung mehrlagiger Leiterplatten für mechatronische Vorrichtungen im automobilen Bereich bekannt, die für Hochstrom - und Signalstrom - Anwendungen geeignet sind.EP 1363483 A2 discloses a method for producing multilayer printed circuit boards for mechatronic devices in the automotive sector, which are suitable for high current and signal current applications.
Es ist Aufgabe der Erfindung, eine Hochvoltbatterie dahingehend zu verbessern, dass sie niederere Kosten für Herstellung, Montage und Logistik verursacht. Erfindungsgemäß ist die Deckplatte eine mehrlagige Leiterplatte mit mindestens zwei leitenden Lagen, deren erste an der den Zellen zugewandten Seite der Leiterplatte angebracht und zur Bildung der Hochstrom -Verbinder von erheblicher Dicke ist, und deren zweite Lage von geringer Dicke ist und die Verbindungsleitungen zur Zeilüberwachungseinheit bildet, wobei die beiden Lagen an gewissen Stellen mittels leitend ausgestalteter, die Leiterplatte durchsetzender Bohrungen miteinander verbunden sind.It is an object of the invention to improve a high-voltage battery in such a way that it causes lower costs for manufacturing, assembly and logistics. According to the invention, the cover plate is a multilayer printed circuit board having at least two conductive layers, the first of which is attached to the side of the printed circuit board facing the cells and of substantial thickness to form the high current connectors, and the second layer is of small thickness and forms the connecting leads to the cell monitoring unit , wherein the two layers are connected at certain points by means of conductive configured, passing through the circuit board holes.
Die leitenden Lagen sind mittels bekannter Abtrag- beziehungsweise Ätzverfahren behandelt, sodass sie die Leiter bilden. Wenn die Deckplatte mit ihrer dicken Schicht, aus der das Material zwischen den Leitern abgetragen ist, auf den Polen der Zellen aufliegt, so sind diese direkt ohne weitere Verbindungselemente an die Leiter angeschlossen. Die in der weiteren dünnen leitenden Schicht ausgebildeten Leiter ist über die Löcher mit den entsprechenden Messpunkten, meist auf den stromführenden Leitern, verbunden. Auf diese Weise sind mit einer einzigen Platte ohne weitere Montagearbeiten alle nötigen Verbindungen hergestellt.The conductive layers are treated by known ablation or etching processes so that they form the conductors. When the cover plate with her thick layer, from which the material is removed between the conductors, rests on the poles of the cells, so these are connected directly without further connecting elements to the conductors. The conductor formed in the further thin conductive layer is connected via the holes to the corresponding measuring points, usually on the current-carrying conductors. In this way, all necessary connections are made with a single plate without further assembly work.
In Weiterbildung der Erfindung enthält die zweite Lage auch die die ZeIl- überwachungseinheit bildenden Bauelemente. Damit ist ein denkbar hoher Integrationsgrad erreicht.In a development of the invention, the second layer also contains the components forming the signal monitoring unit. This achieves a conceivably high level of integration.
