Description
Gebiet der Erfindungfield of invention
Die Erfindung betrifft Fahrzeugrahmen einer Batterieeinheit eines Fahrzeugs.The invention relates to a vehicle frame of a battery unit of a vehicle.
Hintergrund der ErfindungBackground of the Invention
Batterien werden als Komponenten in bestehenden Fahrzeugen meist im Fahrzeugboden verbaut.Batteries are usually installed as components in existing vehicles in the vehicle floor.
Aus der
Zusammenfassung der ErfindungSummary of the Invention
Es ist daher eine Aufgabe der vorliegenden Erfindung, einen Fahrzeugrahmen einer Batterieeinheit zur Verfügung zu stellen, welcher Bauraumoptimiert ist und zugleich ein geringes Gesamtgewicht aufweist.It is therefore an object of the present invention to provide a vehicle frame for a battery unit which is space-optimized and at the same time has a low overall weight.
Erfindungsgemäß wird diese Aufgabe gelöst durch einen Fahrzeugrahmen einer Batterieeinheit eines Fahrzeugs, welcher eine Mehrzahl von Batteriemodulen in einem Speichergehäuse aufweist, umfassend einen Fahrzeugboden und mindestens einen Sitzbereich, wobei der Fahrzeugboden und/oder der Sitzbereich jeweils als Gehäuseteil des Speichergehäuses ausgebildet sind.According to the invention, this object is achieved by a vehicle frame of a battery unit of a vehicle, which has a plurality of battery modules in a storage housing, comprising a vehicle floor and at least one seating area, wherein the vehicle floor and/or the seating area are each designed as a housing part of the storage housing.
Gemäß der Erfindung wird der Fahrzeugboden und/oder der Sitzbereich jeweils als Gehäuseteil des Speichergehäuses genutzt. Hierdurch ist es möglich den Bauraum im Fahrzeugunterboden zu verbessern und Gewicht zu reduzieren.According to the invention, the vehicle floor and/or the seating area is used as a housing part of the storage housing. This makes it possible to improve the installation space in the vehicle underbody and to reduce weight.
Bevorzugterweise sind die Batteriezellen einzeln in dem Speichergehäuse angeordnet. Hierdurch ist es möglich die Batteriezellen Bauraumsparend anzuordnen. Gemäß einer Ausgestaltung der Erfindung sind die Batteriezellen mittels Gitterstruktur voneinander getrennt angeordnet. Dieser Aufbau dient neben der elektrischen und thermischen Isolierung als Crashstruktur des Fahrzeugs. Daneben kann durch den sog. Offenen Verbau der Batteriezellen die elektrische Verschaltung variiert werden. Wodurch die Batteriegröße flexibel an die Anforderungen angepasst werden kann.The battery cells are preferably arranged individually in the storage housing. This makes it possible to arrange the battery cells in a space-saving manner. According to one embodiment of the invention, the battery cells are arranged separately from one another by means of a grid structure. In addition to electrical and thermal insulation, this structure serves as the vehicle's crash structure. In addition, the electrical wiring can be varied through the so-called open installation of the battery cells. This means that the battery size can be flexibly adapted to the requirements.
Gemäß einer Ausgestaltung der Erfindung werden die Batteriezellen als Rundzellen ausgeführt und werden in eine Wabenstruktur eingesetzt. Durch die Wabenstruktur kann die Anzahl der Zellen leicht an die Fahrzeuggröße angepasst werden. Ferner können gemäß einer weiteren Ausgestaltung der Erfindung die Batteriezellen als Prisma- und/ oder Pouchzellen ausgeführt sein und versetzt zueinander angeordnet werden. Beim Einsatz von Prisma oder Pouchzellen sollte die versetzte Anordnung gewählt werden, um die Steifigkeit in Querrichtung zu erhöhen.According to one embodiment of the invention, the battery cells are designed as round cells and are used in a honeycomb structure. Due to the honeycomb structure, the number of cells can easily be adjusted to the size of the vehicle. Furthermore, according to a further embodiment of the invention, the battery cells can be designed as prism and/or pouch cells and can be arranged offset to one another. When using prism or pouch cells, the staggered arrangement should be chosen in order to increase the rigidity in the transverse direction.
Gemäß einer alternativen Ausführung der Erfindung ist eine Kühlung des Fahrzeugbodens unterhalb der Batteriezellen vorgesehen. Bei den Batteriezellen im Bereich der Sitze kann die Kühlung abhängig von der Fahrzeugstruktur ebenfalls unterhalb der Batteriezellen realisiert werden oder an der Außenseite der Batterieblöcke unter den Sitzen.According to an alternative embodiment of the invention, the vehicle floor is cooled below the battery cells. In the case of the battery cells in the area of the seats, the cooling can also be implemented below the battery cells or on the outside of the battery blocks under the seats, depending on the vehicle structure.
