Description
Die Erfindung betrifft ein Batteriemodul sowie ein Kraftfahrzeug mit einem Batteriemodul.The invention relates to a battery module and a motor vehicle with a battery module.
Aus der
Das erfindungsgemäße Batteriemodul umfasst
- - eine Mehrzahl von Batteriezellengruppen, wobei jede Batteriezellengruppe eine Mehrzahl parallelverschalter Batteriezellen umfasst und wobei jede Batteriezelle eine Längsachse und in Richtung dieser Längsachse zwei gegenüberliegende Enden aufweist, wobei die Batteriezelle am ersten Ende einen Pluspol und am zweiten Ende einen Minuspol aufweist und wobei die Batteriezellen aller Batteriezellengruppen hinsichtlich der Ausrichtung von Pluspol und Minuspolidentisch sind,
- - eine Mehrzahl von ersten Kontaktplatten, welche mit den Pluspolen der Batteriezellen je einer Batteriezellengruppe verbunden sind,
- - eine Mehrzahl von zweiten Kontaktplatten, welche mit den Minuspolen der Batteriezellen je einer Batteriezellengruppe verbunden sind,
- - eine Mehrzahl von Sammelschienen zur Schaltung der Mehrzahl der Batteriezellengruppen in Reihe,
- - wobei die erste Kontaktplatte einer Batteriezellengruppe mit der zweiten Kontaktplatte einer benachbarten Batteriezellengruppe mittels einer oder mehrerer Sammelschienen verbunden ist.
- - a plurality of battery cell groups, each battery cell group comprising a plurality of battery cells connected in parallel and each battery cell having a longitudinal axis and two opposite ends in the direction of this longitudinal axis, the battery cell having a positive pole at the first end and a negative pole at the second end and the battery cells of all Battery cell groups are identical in terms of the orientation of the positive and negative poles,
- - a plurality of first contact plates, which are connected to the positive poles of the battery cells of each battery cell group,
- - a plurality of second contact plates, which are connected to the negative poles of the battery cells of each battery cell group,
- - a plurality of busbars for connecting the plurality of battery cell groups in series,
- - Wherein the first contact plate of a battery cell group is connected to the second contact plate of an adjacent battery cell group by means of one or more busbars.
Die ersten und zweiten Kontaktplatten sind elektrisch leitfähig und dienen zur Parallelschaltung der Batteriezellen einer Batteriezellengruppe.The first and second contact plates are electrically conductive and serve to connect the battery cells of a battery cell group in parallel.
Durch die Verbindung der ersten Kontaktplatte einer Batteriezellengruppe mit der zweiten Kontaktplatte einer benachbarten Batteriezellengruppe mittels der Sammelschienen ermöglicht die Erfindung eine Reihenschaltung von nebeneinander angeordneten Batteriezellengruppen, die jeweils eine Mehrzahl identisch angeordneter Batteriezellen umfassen. Gleichzeitig erlaubt die Anordnung der Batteriezellen, dass im Falle eines erforderlichen Entlüftens bei einem thermischen Durchgehen ausreichende Entlüftungspfade zur Verfügung stehen. Des Weiteren erlaubt die Anordnung der Batteriezellen eine gute Zugänglichkeit für das Verschweißen der Batteriezellen und der Kontaktplatten.By connecting the first contact plate of a battery cell group to the second contact plate of an adjacent battery cell group by means of the busbars, the invention enables series connection of battery cell groups arranged next to one another, each of which comprises a plurality of identically arranged battery cells. At the same time, the arrangement of the battery cells allows sufficient venting paths to be available if venting is required in the event of a thermal runaway. Furthermore, the arrangement of the battery cells allows good accessibility for welding the battery cells and the contact plates.
Bevorzugt umfasst das Batteriemodul ein die Batteriezellengruppen umgebendes Gehäuse. Hierdurch wird ein Schutz der Batteriezellen von äußeren Einflüssen sowie eine Fixierung der Batteriezellengruppen und der Kontaktplatten ermöglicht.The battery module preferably includes a housing surrounding the battery cell groups. This enables the battery cells to be protected from external influences and the battery cell groups and the contact plates to be fixed in place.
Vorzugsweise sind die Sammelscheinen zusätzlich zur Verbindung der Kontaktplatten dazu eingerichtet, die Batteriezellengruppen sowie die ersten und zweiten Kontaktplatten im Gehäuse zu fixieren und/oder das Batteriemodul in einem Fahrzeug zu fixieren.In addition to connecting the contact plates, the busbars are preferably set up to fix the battery cell groups and the first and second contact plates in the housing and/or to fix the battery module in a vehicle.
