Description

Die Erfindung betrifft eine Batterieanordnung, insbesondere für mobile Anwendungen, bei welcher mehrere Zellen zu einer Batterie zusammengefasst sind.The invention relates to a battery assembly, in particular for mobile applications, in which a plurality of cells are combined to form a battery.

Zur Erzielung einer ausreichenden Kapazität bzw. Spannung werden Batterien meistens aus mehreren Zellen zusammengesetzt. Werden aus derartigen Batterien hohe Leistungen entnommen, tritt eine Erwärmung ein. Diese muss gegebenenfalls durch Kühlung abgeführt werden. Es ist deshalb bereits vorgeschlagen worden, die einzelnen Zellen nicht zu vergießen, damit ein Kühlmedium an die Zellen herangeführt werden kann. Bei vielen Anwendungen ist jedoch eine geschlossene Bauform erwünscht.To achieve sufficient capacity or voltage, batteries are usually composed of several cells. If high power is removed from such batteries, heating occurs. If necessary, this must be removed by cooling. It has therefore already been proposed not to shed the individual cells, so that a cooling medium can be brought to the cells. In many applications, however, a closed design is desired.

Aufgabe der Erfindung ist es daher, unter Beibehaltung einer effizienten Kühlung eine geschlossen Bauform anzugeben.The object of the invention is therefore to specify a closed design while maintaining efficient cooling.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass ein Gehäuse für die Batterie vorgesehen ist, das ein Gehäuseunterteil und einen Gehäusedeckel aufweist, welche zueinander abgedichtet sind und wobei mindestens der Gehäusedeckel aus Kunststoff besteht, dass mindestens das Gehäuseunterteil aus einem wärmeleitenden Werkstoff besteht und dass die Anschlüsse der Batterie aus dem Deckel gedichtet herausgeführt sind.This object is achieved in that a housing for the battery is provided, which has a lower housing part and a housing cover, which are sealed to each other and wherein at least the housing cover is made of plastic, that at least the lower housing part consists of a thermally conductive material and that the connections the battery are led out sealed from the lid.

Die Erfindung hat den Vorteil, dass die einzelnen Zellen der Batterie nicht den Umwelteinflüssen ausgesetzt sind, wie sie beispielsweise in Fahrzeugen auftreten. Außer einer mobilen Anwendung der Erfindung kommen auch andere Anwendungen in Frage.The invention has the advantage that the individual cells of the battery are not exposed to the environmental influences, as they occur, for example, in vehicles. Apart from a mobile application of the invention, other applications come into question.

Zur Verbindung des Gehäusedeckels mit dem Gehäuseunterteil stehen dem Fachmann verschiedene Möglichkeiten zur Verfügung, beispielsweise Verschweißen oder Verkleben, wenn eine feste Verbindung erforderlich ist, oder lösbare Verbindungselemente mit einer elastischen Dichtung.For connecting the housing cover to the housing base, the person skilled in various options available, for example, welding or bonding, if a solid connection is required, or releasable fasteners with an elastic seal.

Eine vorteilhafte Ausführungsform der Erfindung besteht darin, dass der Gehäusedeckel aus wärmeleitendem Kunststoff besteht. Derartige Kunststoffe stehen dem Fachmann zur Verfügung. Als Werkstoffe kommen beispielsweise Polyamide, Polypropylen, Polyoxymethylen, Polybutylenterephthalat oder Polycarbonate in Frage. Um die Hitzebeständigkeit und/oder die Steifigkeit des Kunststoffs zu erhöhen, kann der Kunststoff beispielsweise mit Talkum, Glasfasern oder Glaskugeln versehen sein. Die Batteriezellen können auch ganz oder teilweise von dem wärmeleitenden Kunststoff umschlossen sein.An advantageous embodiment of the invention is that the housing cover consists of thermally conductive plastic. Such plastics are available to the person skilled in the art. Suitable materials include for example polyamides, polypropylene, polyoxymethylene, polybutylene terephthalate or polycarbonates in question. In order to increase the heat resistance and / or the rigidity of the plastic, the plastic may be provided, for example, with talc, glass fibers or glass beads. The battery cells can also be completely or partially enclosed by the heat-conducting plastic.

Bezüglich des Gehäuseunterteils sind verschiedene Ausführungsformen möglich. Eine davon besteht darin, dass das Gehäuseunterteil aus Kunststoff besteht. Auch wenn eine gewisse Wärmeableitung bei üblichen Kunststoffen möglich ist, beispielsweise durch eine geringe Wandstärke, kann diese Ausführungsform in vorteilhafter Weise dadurch weitergebildet werden, dass das Gehäuseunterteil aus wärmeleitendem Kunststoff besteht.With respect to the lower housing part, various embodiments are possible. One of them is that the housing base is made of plastic. Although a certain heat dissipation in conventional plastics is possible, for example, by a small wall thickness, this embodiment can be further developed in an advantageous manner that the lower housing part consists of thermally conductive plastic.

Schließlich kann bei der Erfindung vorgesehen sein, dass das Gehäuseunterteil aus Metall besteht. Zur Herstellung des Gehäusedeckels und des Gehäuseunterteils stehen verschiedene Verfahren zur Verfügung, beispielsweise Spritzguss oder Tiefziehen.Finally, it can be provided in the invention that the lower housing part consists of metal. Various methods are available for producing the housing cover and the housing lower part, for example injection molding or deep drawing.

Eine Weiterbildung der Erfindung besteht darin, dass im Gehäusedeckel eine gegenüber dem Gehäusedeckel abgedichtete, herausnehmbare Anzeige- und Steuereinrichtung für die Anzeige des jeweiligen Ladezustandes der Batterie und für die Überwachung und/oder Begrenzung der Entladung vorgesehen ist. Dabei ist vorzugsweise vorgesehen, dass die Anzeige- und Steuereinrichtung bezüglich der Entnahmeströme konfigurierbar ist. Eine Konfiguration kann beispielsweise über eine an der Anzeige- und Steuereinrichtung vorgesehene USB-Schnittstelle vorgenommen werden.A development of the invention consists in the fact that a removable display and control device, which is sealed off from the housing cover, is provided in the housing cover for the display of the respective state of charge of the battery and for the monitoring and / or limitation of the discharge.

Damit kann beispielsweise die Anzeige- und Steuereinrichtung im Blickfeld eines Fahrers montiert werden.This development can be designed such that the display and control device has a connection cable to the battery. Thus, a reading of the display can also be made when the battery is located in inaccessible places. It can also be provided that the display and control device has elements for attachment to a vehicle part. Thus, for example, the display and control device can be mounted in the field of vision of a driver.

Eine weitere Funktion der Anzeige- und Steuereinrichtung wird dadurch ermöglicht, dass die Anzeige- und Steuereinrichtung mit einem Thermosensor verbunden ist, der die Temperatur des Gehäuses überwacht, und je nach Wärmeentwicklung den Ladestrom auf einen zulässigen Wert begrenzt.Another function of the display and control device is made possible by the fact that the display and control device is connected to a thermal sensor, which monitors the temperature of the housing, and limited depending on the evolution of heat, the charge current to an allowable value.

Eine Weiterbildung der Erfindung ohne eine besondere Steuerung des Lade- und Entladevorgangs besteht darin, dass im Gehäusedeckel eine gegenüber dem Gehäusedeckel abgedichtete, herausnehmbare Anzeige- und Überwachungseinrichtung zur Erkennung eines Ausnahmezustandes vorgesehen ist, welche die Batterie von den Anschlüssen trennt oder die Belastung auf eine minimale Stufe beschränkt.A development of the invention without a special control of the charging and discharging process is that in the housing cover a sealed relative to the housing cover, removable display and monitoring device is provided for detecting a state of emergency, which separates the battery from the terminals or the load to a minimum Level limited.

Wird eine Entnahme der Batterie, beispielsweise zu Wartungszwecken, gefordert, kann gemäß einer weiteren Ausführungsform vorgesehen sein, dass der Gehäusedeckel mit dem Gehäuseunterteil mit Verschlüssen verbunden ist, die nur mit Spezialschlüsseln lösbar sind. Diese Ausführungsform hat den Vorteil, dass eine Öffnung des Gehäuses berechtigten Personen vorbehalten bleibt, beispielsweise in Vertragswerkstätten.If a removal of the battery, for example for maintenance purposes, required, it can be provided according to a further embodiment, that the housing cover is connected to the lower housing part with closures, which are solvable only with special keys.
