Description
Die Erfindung betrifft eine Stromversorgungseinrichtung, insbesondere für Kraftfahrzeuge, mit
- – einem aus mindestens einem Batteriemodul bestehenden Batteriestack zur Bereitstellung elektrischer Energie und
- – einem auf dem Batteriestack montierten Batteriemanagementsystem zur Zustandsüberwachung des Batteriemoduls,
- - One consisting of at least one battery module battery pack for providing electrical energy and
- A battery management system mounted on the battery stack for condition monitoring of the battery module,
Batteriestacks für Kraftfahrzeuge dienen zur Bereitstellung elektrischer Energie für den Fahrzeugantrieb und bestehen in der Regel aus mehreren, häufig plattenförmigen, Batteriemodulen, die miteinander elektrisch verschaltet sind. Zur Zustandsüberwachung der Batteriemodule wird ein so genanntes Batteriemanagementsystem eingesetzt, das im Stand der Technik über eine separate Verdrahtung mit den einzelnen Batteriemodulen des Batteriestacks elektrisch verbunden ist. Die Überwachung erfolgt beispielsweise hinsichtlich des Spannungsniveaus und/oder der Temperatur der einzelnen Batteriemodule, wobei die Temperatur zum Beispiel mittels Thermoelementen erfasst wird. Sofern das Spannungsniveau und/oder die Temperatur im einzelnen Batteriemodul von einem bestimmten Sollwert zu stark abweicht, meldet das Batteriemanagementsystem eine entsprechende Warnung und schaltet ggf. auch dieses Batteriemodul aus Sicherheitsgründen ab.Battery stacks for motor vehicles are used to provide electrical energy for the vehicle drive and usually consist of several, often plate-shaped, battery modules that are electrically interconnected. For condition monitoring of the battery modules, a so-called battery management system is used, which is electrically connected in the prior art via a separate wiring with the individual battery modules of the battery stack. The monitoring takes place, for example, with regard to the voltage level and / or the temperature of the individual battery modules, wherein the temperature is detected, for example, by means of thermocouples. If the voltage level and / or the temperature in the individual battery module deviates too much from a specific setpoint value, the battery management system reports a corresponding warning and possibly also switches off this battery module for safety reasons.
Gemäß dem Stand der Technik erfolgt die elektrische Kontaktierung der Batteriemodule mit dem Batteriemanagementsystem üblicherweise mittels einer Schraubverbindung oder mittels einer Verlötung, die einen großen Aufwand bei der Erstmontage der Stromversorgungseinrichtung verursacht. Insbesondere sofern ein Batteriemodul – beispielsweise aufgrund einer vom Batteriemanagementsystem ermittelten Sollwertabweichung bzgl. der Temperatur und/oder des Spannungsniveaus – ausgetauscht werden muss, ist ebenfalls ein großer Arbeitsaufwand erforderlich, um die Lötverbindung zu entfernen und eine neue Lötverbindung am neuen Batteriemodul anzubringen. Darüber hinaus besteht die Gefahr von fehlerhaften Verlötungen, so genannten kalten Lötstellen. Auch bei der beschrieben Schraubverbindung muss der elektrische Kontakt zwischen Batteriemanangementsystem und Batteriestack über einen separaten Arbeitsgang hergestellt werden.According to the prior art, the electrical contacting of the battery modules with the battery management system is usually carried out by means of a screw connection or by means of a soldering, which causes a great deal of effort in the initial installation of the power supply device. In particular, if a battery module - for example due to a determined by the battery management system setpoint with respect to the temperature and / or voltage levels - must be replaced, also a large amount of work is required to remove the solder joint and attach a new solder joint on the new battery module. In addition, there is the risk of incorrect soldering, so-called cold solder joints. Even with the described screw the electrical contact between battery management system and battery stack must be made via a separate operation.
Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, eine Stromversorgungseinrichtung mit den eingangs beschriebenen Merkmalen anzugeben, die einfach montierbar ist und darüber hinaus einen einfach durchzuführenden und kostengünstigen Austausch eines defekten Batteriemoduls gewährleistet.Against this background, the invention has for its object to provide a power supply device with the features described above, which is easy to install and also ensures an easy to perform and inexpensive replacement of a defective battery module.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass zwischen Batteriemanagementsystem und Batteriestack zur Herstellung des elektrischen Kontaktes elektrisch leitende Zwischenelemente vorgesehen sind, die durch die Montage des Batteriemanagementsystems auf den Batteriestack mechanisch vorgespannt sind. Die erfindungsgemäße, auf einer Klemmwirkung basierende elektrische Kontaktierung des Batteriemoduls erlaubt eine einfache Erstmontage der Stromversorgungseinrichtung und auch einen sehr einfachen Austausch eines defekten Batteriemoduls, da die Klemmwirkung bei der ohnehin obligatorischen Demontage des Batteriemanagementsystems zum Austausch des Batteriemoduls automatisch aufgehoben wird. Insofern erfolgt erfindungsgemäß durch die Montage des Batteriemanagementsystems auf dem Batteriestack gleichsam auch die Herstellung des elektrischen Kontaktes zum Batteriemodul in einem einzigen Arbeitsgang. Eine separate Herstellung des elektrischen Kontaktes vor der Montage des Batteremanagementsystems auf dem Batteriestack ist nicht mehr erforderlich. Die Demontage des Batteriemanagementsystems vom Batteriestack verursacht entsprechend unmittelbar auch eine Trennung der elektrischen Verbindung zwischen defektem Batteriemodul und Batteriemanagementsystem, wodurch der Austausch des defekten Batteriemoduls durch ein neues Element sehr schnell und ohne großen Aufwand durchgeführt werden kann.According to the invention the object is achieved in that electrically conductive intermediate elements are provided between the battery management system and battery stack for the production of electrical contact, which are mechanically biased by the mounting of the battery management system on the battery stack. The inventive, based on a clamping action electrical contact of the battery module allows a simple initial installation of the power supply device and a very simple replacement of a defective battery module, since the clamping effect is automatically canceled in the already mandatory disassembly of the battery management system for replacing the battery module. In this respect, according to the invention, the assembly of the battery management system on the battery stack also makes the production of the electrical contact to the battery module in a single operation. A separate production of the electrical contact before mounting the battery management system on the battery pack is no longer necessary. The disassembly of the battery management system from the battery stack causes immediately correspondingly a separation of the electrical connection between the defective battery module and the battery management system, whereby the replacement of the defective battery module can be performed by a new element very quickly and easily.
Gemäß einer besonders zweckmäßigen Ausführungsform der Erfindung sind die Zwischenelemente als Federelemente ausgebildet. Diese erfahren aufgrund ihrer Kompression bei der Montage des Batteriemanagementsystems auf dem Batteriestack eine entsprechende Vorspannung, so dass auch bei sehr unruhiger Fahrt des Kraftfahrzeuges eine sichere elektrische Verbindung zwischen Batteriemanagementsystem und Batteriestack gewährleistet ist. Die Federelemente können hierbei als Schraubenfedern und/oder Blattfedern ausgebildet sein.According to a particularly advantageous embodiment of the invention, the intermediate elements are designed as spring elements. These learn due to their compression in the installation of the battery management system on the battery stack a corresponding bias, so that even with very restless drive of the motor vehicle, a secure electrical connection between the battery management system and battery stack is guaranteed. The spring elements may in this case be designed as coil springs and / or leaf springs.
Im Rahmen der Erfindung liegt es aber auch, dass die Zwischenelemente eine Steckverbindung zwischen dem Batteriemanagementsystem und elektrischen Kontaktelementen des Batteriemoduls herstellen. Auch bei dieser Verbindungsart werden die Zwischenelemente bei der Montage des Batteriemanagementsystems mechanisch vorgespannt und hierbei auf den elektrischen Kontaktelementen des Batteriemoduls festgeklemmt. Auf diese Weise wird ebenfalls eine sichere elektrische Verbindung zwischen Batteriemanagementsystem und Batteriemodul gewährleistet, die auch bei erheblichen Fahrzeugerschütterungen erhalten bleibt.In the context of the invention, however, it is also the case that the intermediate elements produce a plug connection between the battery management system and electrical contact elements of the battery module. Also in this type of connection, the intermediate elements are mechanically biased during assembly of the battery management system and thereby clamped on the electrical contact elements of the battery module. In this way, a secure electrical connection between the battery management system and battery module is also guaranteed, which is maintained even in significant vehicle vibrations.
Zweckmäßigerweise weist das Batteriemanagementsystem eine Platine auf, auf der – vorzugsweise an deren Unterseite – die Zwischenelemente gemeinsam angeordnet sind. Zwecks Vermeidung einer Beeinträchtigung der elektrischen Verbindung durch Korrosion können die Zwischenelemente an den elektrischen Kontaktstellen auch vergoldet sein. Conveniently, the battery management system has a board on which - preferably on the underside - the intermediate elements are arranged together. In order to avoid deterioration of the electrical connection by corrosion, the intermediate elements may also be gold plated at the electrical contact points.
Im Rahmen der Erfindung liegt es ferner, dass der Batteriestack mehrere Batteriemodule aufweist, die gemeinsam in einer rahmenförmigen Aufnahmevorrichtung des Batteriemanagementsystems zusammengefasst sind. Bei dieser Ausführungsform der Erfindung übernimmt das Batteriemanagementsystem zusätzlich die Funktion der Vereinigung der einzelnen, üblicherweise plattenförmig ausgebildeten, Batteriemodule zum Batteriestack.In the context of the invention, it is further the case that the battery stack has a plurality of battery modules, which are combined together in a frame-shaped receiving device of the battery management system. In this embodiment of the invention, the battery management system additionally assumes the function of uniting the individual, usually plate-shaped, battery modules to the battery pack.
Das Batteriemanagementsystem weist zweckmäßigerweise Einrichtungen zur Überwachung der Temperatur und/oder des Spannungsniveaus in dem Batteriemodul auf. Die hierzu beispielsweise eingesetzten Temperatursensoren können derart angeordnet sein, dass unmittelbar die Temperatur an der Oberfläche des Batteriemoduls gemessen wird. Es ist allerdings auch möglich, mit Hilfe der Temperatursensoren die Temperatur in den Zwischenelementen zu messen. Diese besitzen aufgrund ihrer guten elektrischen Leitfähigkeit in der Regel auch eine gute Wärmeleitfähigkeit, so dass anhand deren Temperatur ein Rückschluss auf die Oberflächentemperatur des entsprechenden Batteriemoduls möglich ist. Hinsichtlich der Temperaturmessung ist es auch denkbar, dass auf der Platine des Batteriemanagementsystems Temperatursensoren vorgesehen sind, die über Wärmeleitpaste mit dem Batteriemodul verbunden sind. Das Batteriemanagementsystem kann auf den Batteriestack aufgeschraubt oder aufgeclipst sein. Durch diesen Montagevorgang wird automatisch die elektrische Verbindung von Batteriemanagementsystem und Batteriestack hergestellt, so dass ein separater Montagevorgang zur Herstellung dieser Verbindung entfällt.The battery management system expediently has means for monitoring the temperature and / or the voltage level in the battery module. The temperature sensors used for this purpose, for example, can be arranged such that the temperature on the surface of the battery module is measured directly. However, it is also possible to measure the temperature in the intermediate elements with the aid of the temperature sensors. Due to their good electrical conductivity, these generally also have a good thermal conductivity, so that a conclusion on the surface temperature of the corresponding battery module is possible on the basis of their temperature. With regard to the temperature measurement, it is also conceivable that temperature sensors are provided on the board of the battery management system, which are connected via thermal grease to the battery module. The battery management system can be screwed or clipped onto the battery stack. This assembly process automatically establishes the electrical connection between the battery management system and the battery stack so that a separate assembly process for producing this connection is eliminated.
Gegenstand der Erfindung ist auch ein Kraftfahrzeug, insbesondere Elektro-Kraftfahrzeug mit einer Stromversorgungseinrichtung nach einem der Ansprüche 1–9.The invention is also a motor vehicle, in particular electric motor vehicle with a power supply device according to one of claims 1-9.
