Description
Die Erfindung betrifft ein Batteriemodulgehäuse zum Aufnehmen zumindest einer Batteriezelle in einem Innenraum des Batteriemodulgehäuses gemäß dem Oberbegriff von Patentanspruch 1. Ferner betrifft die Erfindung ein Batteriemodulgehäuse.The invention relates to a battery module housing for accommodating at least one battery cell in an interior space of the battery module housing according to the preamble of patent claim 1. The invention also relates to a battery module housing.
Aus dem Stand der Technik ist bereits bekannt, dass eine Fahrzeugbatterie beziehungsweise ein Batteriemodul bei einem Fahrzeug-Crash eine Intrusion erfahren kann. Zur Erreichung einer hohen Energiedichte ist es erforderlich, die Zellmodule in die mechanische Struktur der Batterie einzubeziehen. Dafür gibt es die Gefahr der Intrusion in die Batteriezellen, wodurch ein thermisches Event ausgelöst werden kann, und damit die Sicherheit des Fahrzeugnutzers gefährdet werden könnte.It is already known from the prior art that a vehicle battery or a battery module can experience an intrusion in the event of a vehicle crash. To achieve a high energy density, it is necessary to include the cell modules in the mechanical structure of the battery. Instead, there is a risk of intrusion into the battery cells, which can trigger a thermal event and thus endanger the safety of the vehicle user.
Die
Aufgabe der vorliegenden Erfindung ist es, ein Batteriemodulgehäuse sowie ein Batteriemodul zu schaffen, mittels welchen die Sicherheit im Straßenverkehr für ein Kraftfahrzeug erhöht werden kann.The object of the present invention is to create a battery module housing and a battery module by means of which road safety for a motor vehicle can be increased.
Diese Aufgabe wird durch ein Batteriemodulgehäuse sowie durch ein Batteriemodul gemäß den unabhängigen Patentansprüchen gelöst. Vorteilhafte Ausgestaltungsformen sind in den Unteransprüchen angegeben.This object is achieved by a battery module housing and by a battery module according to the independent claims. Advantageous embodiments are specified in the subclaims.
Ein Aspekt der Erfindung betrifft ein Batteriemodulgehäuse zum Aufnehmen zumindest einer Batteriezelle in einem Innenraum des Batteriemodulgehäuses, mit zumindest einem äußeren Gehäuseteil und mit einem inneren Gehäuseteil, wobei durch das innere Gehäuseteil der Innenraum für die zumindest eine Batteriezelle gebildet ist und wobei das äußere Gehäuseteil zum Anordnen an einem Bauteil eines Kraftfahrzeugs ausgebildet ist.One aspect of the invention relates to a battery module housing for accommodating at least one battery cell in an interior of the battery module housing, with at least one outer housing part and with an inner housing part, with the inner housing part forming the interior space for the at least one battery cell and with the outer housing part for arrangement is formed on a component of a motor vehicle.
Es ist vorgesehen, dass zwischen dem inneren Gehäuseteil und dem äußeren Gehäuseteil eine zusätzliche Hohlkammer ausgebildet ist.It is provided that an additional hollow chamber is formed between the inner housing part and the outer housing part.
Insbesondere ist somit an dem Batteriemodulgehäuse ein Crash-Absorber ausgebildet, der einen Intrusionsraum bietet und/oder Crash-Energie absorbiert. Insbesondere kann somit eine kostengünstige Lösung eines Crash-Absorbers durch Integration in das seitliche Strangpressprofil eines Batteriemodulgehäuses realisiert werden. Dadurch kann eine höhere Batteriedichte sowie die Sicherheit durch Schutz des aktiven Zellmaterials realisiert werden.In particular, a crash absorber is thus formed on the battery module housing, which offers an intrusion space and / or absorbs crash energy. In particular, a cost-effective solution for a crash absorber can be implemented by integrating it into the lateral extruded profile of a battery module housing. As a result, a higher battery density and safety can be achieved by protecting the active cell material.
Gemäß einer vorteilhaften Ausgestaltungsform ist die Hohlkammer als Strangpressprofil oder als Rollprofil ausgebildet.According to an advantageous embodiment, the hollow chamber is designed as an extruded profile or as a rolled profile.
Weiterhin vorteilhaft ist, wenn das innere Gehäuseteil mit dem äußeren Gehäuseteil auf einer Innenseite des äußeren Gehäuseteils verklebt sind.It is also advantageous if the inner housing part are glued to the outer housing part on an inside of the outer housing part.
Es hat sich weiterhin als vorteilhaft erwiesen, wenn die Hohlkammer an einer Außenseite und/oder Innenseite der Hohlkammer zumindest eine Sollknickstelle aufweist.It has also proven to be advantageous if the hollow chamber has at least one predetermined kink on an outside and / or inside of the hollow chamber.
In einer weiteren vorteilhaften Ausgestaltungsform ist die Hohlkammer an einem Seitenbereich des Batteriemodulgehäuses ausgebildet.In a further advantageous embodiment, the hollow chamber is formed on a side area of the battery module housing.
Ein weiterer Aspekt der Erfindung betrifft ein Batteriemodul für ein Kraftfahrzeug mit zumindest einer Batteriezelle und mit einem Batteriemodulgehäuse nach dem vorhergehenden Aspekt.Another aspect of the invention relates to a battery module for a motor vehicle with at least one battery cell and with a battery module housing according to the preceding aspect.
Ebenfalls betrifft die Erfindung ein Kraftfahrzeug mit einem Batteriemodul nach dem vorhergehenden Aspekt. Das Kraftfahrzeug ist insbesondere als zumindest teilweise elektrisch betriebenes Kraftfahrzeug beziehungsweise als vollelektrisch betriebenes Kraftfahrzeug ausgebildet. Vorteilhafte Ausgestaltungsformen des Batteriemodulgehäuses sind als vorteilhafte Ausgestaltungsformen des Batteriemoduls sowie des Kraftfahrzeugs anzusehen.The invention also relates to a motor vehicle with a battery module according to the preceding aspect. The motor vehicle is designed in particular as an at least partially electrically operated motor vehicle or as a fully electrically operated motor vehicle. Advantageous configurations of the battery module housing are to be regarded as advantageous configurations of the battery module and of the motor vehicle.
