The selection of materials and the production of printed circuit boards on a metal substrate, so-called metal core printed circuit boards (MCPCB), are known to the person skilled in the art.

Üblicherweise werden dabei Epoxyd-Glasfasergewebe (FR4)-Leiterplatten über eine dielektrische Schicht, meist ein elektrisch isolierender, aber thermisch gut leitfähiger Kleber, auf ein Metallsubstrat aus Aluminium oder Kupfer aufgebracht. Typically, epoxy glass fiber fabric (FR4) printed circuit boards are applied to a metal substrate made of aluminum or copper via a dielectric layer, usually an electrically insulating but thermally highly conductive adhesive.

Diese Leiterplattentechnologie hat den Vorteil, dass im Vergleich zu This printed circuit board technology has the advantage that compared to

Standardleiterplatten sehr geringe thermische Übergangswiderstände realisiert werden können. Daher wird diese Technik bei Anwendungen eingesetzt, bei denen die elektronischen Bauelemente mit größeren Verlustleistungen betrieben werden, oder bei Anwendungen, bei denen die Leistungsfähigkeit der eingesetzten Bauelemente mit zunehmender Temperatur zurückgeht.

Direct application of monitoring electronics for a battery cell on the housing cover has the following advantages:

- Da die Überwachungselektronik sehr gut thermisch an den Gehäusedeckel gekoppelt ist, kann die Temperatur der Batterie sehr genau und kostengünstig erfasst werden. - Since the monitoring electronics is very well thermally coupled to the housing cover, the temperature of the battery can be detected very accurately and inexpensively.

Bei Anordnung der Uberwachungselektronik ganz oder teilweise direkt im Gehäuse bzw. der Batteriezelle kann vorteilhafterweise z. B. die Temperatur unmittelbar gemessen werden. Dadurch kann zusätzliche Information bzw. gegebenenfalls auch genauere Information über den Zustand der Batteriezelle gewonnen werden.

Elektrodenpotentialen erfolgen kann. - Die Überwachungselektronik muss nicht separat mechanisch fixiert werden, da diese mit dem Gehäusedeckel mechanisch robust verbunden ist.  Electrode potentials can be done. - The monitoring electronics need not be separately mechanically fixed, as this is mechanically robust connected to the housing cover.

Die Uberwachungselektronik ist mit einer spezifischen Batteriezelle dauerhaft verbunden, so dass relevante Betriebsdaten, welche die Alterung einer Batteriezelle maßgeblich beeinflussen, aufgezeichnet werden können. Dies ist zum einen von Vorteil für die Gewährleistung, zum anderen können diese Informationen auch für ein sogenanntes "Second Life", das heißt eine The monitoring electronics are permanently connected to a specific battery cell, so that relevant operating data, which significantly influence the aging of a battery cell, can be recorded. This is on the one hand advantageous for the warranty, on the other hand, this information can also for a so-called "Second Life", that is one

Wiederverwendung in einem anderen Bereich dienen. Dies ist ein  Serve reuse in another area. This is a

entscheidender Vorteil insbesondere vor dem Hintergrund, dass  decisive advantage in particular against the background that

Fahrzeughersteller heute schon Gewährleistungszeiträume von 10 Jahren und mehr von den Batteriezellherstellern fordern.  Vehicle manufacturers today already demand warranty periods of 10 years and more from the battery cell manufacturers.

Die Aufbringung der Elektronik am Gehäusedeckel eignet sich für den Einsatz der Batteriezellen in Batteriemodulen, bei denen die Zellen über die großflächige Stirnseite miteinander in einem Pressverband verbaut werden. Derartige Batteriemodule werden insbesondere dann eingesetzt, wenn die Batteriezellen zur Erhöhung ihrer Lebensdauer durch mechanische Verspannung daran gehindert werden, sich mechanisch bei Lade- und Entladevorgängen The application of the electronics on the housing cover is suitable for the use of battery cells in battery modules, in which the cells are installed on the large-scale front side together in a press fit. such Battery modules are used in particular when the battery cells are prevented from increasing their life by mechanical tension from being mechanically during charging and discharging

auszudehnen, der dadurch generierte mechanische Stress würde eine schnellere Alterung der Zellen bewirken. expand, the mechanical stress generated thereby would cause a faster aging of the cells.

Die Aufbringung der Elektronik auf den Gehäusedeckel eignet sich auch für ein Batteriesystem, bei dem die Zellen über einen Luftstrom gekühlt werden. In diesem Fall werden die Zellen nicht direkt gegeneinander gepresst, sondern mittels Abstandhalter verbaut, damit der Luftstrom zwischen den Zellen durchströmen kann. The application of the electronics on the housing cover is also suitable for a battery system in which the cells are cooled by an air flow. In this case, the cells are not pressed directly against each other, but installed by means of spacers, so that the air flow between the cells can flow through.

Gegenstand der Erfindung ist zudem ein Kraftfahrzeug mit einem elektrischen Antriebsmotor zum Antreiben des Kraftfahrzeugs und einem mit dem elektrischen Antriebsmotor verbundenen oder verbindbaren Batteriemodul, das voranstehend beschrieben ist.
