Description
Die vorliegende Erfindung betrifft ein Zellgehäuse für eine Batteriezelle, das ausgebildet ist, ein in das Zellgehäuse einzufüllendes Elektrolyt und andere elektrochemische Batteriekomponenten aufzunehmen, die zur Erzeugung einer an Terminals der Batteriezelle bereitzustellenden Batteriespannung in dem Zellgehäuse anzuordnen sind, wobei das Zellgehäuse einen zum Schutz der elektrochemischen Komponenten ausgebildeten Umschließungsabschnitt umfasst.

Furthermore, the invention relates to a battery having a plurality of battery cells.
Stand der TechnikState of the art
Es zeichnet sich ab, dass in Zukunft sowohl bei stationären Anwendungen, wie beispielsweise bei Windkraftanlagen, in Fahrzeugen, wie beispielsweise bei Hybrid- und Elektrofahrzeugen, als auch im Consumer-Bereich, beispielsweise bei Laptops und Mobiltelefonen, vermehrt Batteriesysteme zum Einsatz kommen werden, an die sehr hohe Anforderungen bezüglich Zuverlässigkeit, Leistungsfähigkeit und Lebensdauer gestellt werden. Ein wichtiger Parameter für die Leistungsfähigkeit ist die spezifische Energie. Diese wird in Wattstunden pro Kilogramm (Wh/kg) gemessen und gibt an, wie viel Energie in einem Kilogramm Batterie gespeichert werden kann. Um die spezifische Energie zu erhöhen, wird daher angestrebt, das Gewicht des Batteriesystems zu reduzieren. It is becoming apparent that battery systems will increasingly be used in both stationary applications, such as in wind turbines, in vehicles, such as in hybrid and electric vehicles, and in the consumer sector, for example in laptops and mobile telephones the very high demands are placed on reliability, performance and life. An important parameter for performance is the specific energy. This is measured in watt-hours per kilogram (Wh / kg) and indicates how much energy can be stored in one kilogram of battery. In order to increase the specific energy, it is therefore desirable to reduce the weight of the battery system.
Lithium-Ionen-Batteriezellen sind empfindlich gegenüber äußeren Einflüssen wie Luft oder Feuchtigkeit und müssen daher hinreichend gut geschützt werden. Dies wird beispielsweise mit einem Hardcase-Gehäuse erreicht. Ein Hardcase-Gehäuse besteht typischerweise aus zwei Teilen, dem Gehäusegefäß (Can) und dem Zelldeckel (Cap Plate), die im Fertigungsprozess miteinander verschweißt werden. Eine andere Form von Gehäuse stellt die sogenannte Coffee-Bag-Zelle dar, die ein Gehäuse aus Aluminium-Verbundfolie aufweist. Lithium-ion battery cells are sensitive to external influences such as air or moisture and must therefore be sufficiently well protected. This is achieved, for example, with a hardcase housing. A hardcase housing typically consists of two parts, the housing vessel (Can) and the cell cap (Cap Plate), which are welded together in the manufacturing process. Another form of housing is the so-called coffee bag cell, which has a housing made of aluminum composite foil.
Antriebsbatterien in Hybrid-, Plug-in-Hybrid- und Elektrofahrzeugen werden üblicherweise modular aufgebaut. Hierbei werden aus mindestens zwei einzelnen Batteriezellen, die seriell oder parallel miteinander verschaltet werden, Batteriemodule gebildet, welche wiederum zu sogenannten Subunits, das heißt größere Untereinheiten einer Batterie zusammengefasst werden. Die Batteriemodule einer Untereinheit (Subunit) teilen sich beispielsweise eine gemeinsame Kühleinrichtung oder andere periphere Einrichtungen. Die Batteriemodule und die Untereinheiten können je nach Bauraum auch in mehreren Ebenen übereinander angeordnet sein. Traction batteries in hybrid, plug-in hybrid and electric vehicles are usually modular. In this case, battery modules are formed from at least two individual battery cells, which are connected in series or in parallel, which in turn are combined to form so-called subunits, that is to say larger subunits of a battery. The battery modules of a subunit share, for example, a common cooling device or other peripheral devices. Depending on the installation space, the battery modules and the subunits can also be arranged one above the other in several levels.

Offenbarung der ErfindungDisclosure of the invention
Es wird ein Zellgehäuse für eine Batteriezelle gemäß dem unabhängigen Anspruch 1 zur Verfügung gestellt. Das erfindungsgemäße Zellgehäuse ist ausgebildet, ein in das Zellgehäuse einzufüllendes Elektrolyt und andere elektrochemische Batteriekomponenten aufzunehmen, die in dem Zellgehäuse zur Erzeugung einer an Terminals der Batteriezelle bereitzustellenden Batteriespannung anzuordnen sind, wobei das Zellgehäuse einen zum Schutz der elektrochemischen Komponenten ausgebildeten Umschließungsabschnitt umfasst. Das Zellgehäuse weist einen oder mehrere Halterungsabschnitte auf, die als Halterung zum Befestigen der Batteriezelle an einer Haltestruktur einer Batterie geformt und mit dem Umschließungsabschnitt integral verbundenen sind.A cell case for a battery cell according to independent claim 1 is provided. The cell housing according to the invention is designed to accommodate an electrolyte to be filled into the cell housing and other electrochemical battery components to be arranged in the cell housing for generating a battery voltage to be provided to terminals of the battery cell, wherein the cell housing comprises an enclosing section designed to protect the electrochemical components. The cell case has one or more support portions formed as a holder for fixing the battery cell to a support structure of a battery and integrally connected to the enclosing portion.
Ferner wird nach einem Aspekt der Erfindung auch eine Batterie mit mehreren Batteriezellen gemäß dem Anspruch 5 zur Verfügung gestellt. Die Batterie weist eine Haltestruktur auf und die Batteriezellen sind jeweils mit einem Zellgehäuse gebildet, das einen oder mehrere Halterungsabschnitte aufweist, die als Halterung zum Befestigen der Batteriezelle an der Haltestruktur geformt und mit einem Umschließungsabschnitt des Zellgehäuses integral verbunden sind.Furthermore, according to one aspect of the invention, a battery with a plurality of battery cells according to claim 5 is provided. The battery has a support structure, and the battery cells are each formed with a cell case having one or more support portions formed as a support for fixing the battery cell to the support structure and integrally connected to a containment portion of the cell case.
Ein Vorteil der Erfindung ist, dass die Zellgehäuse derart gestaltet sind, dass sie direkt mit einer Halterungsstruktur, wie zum Beispiel einem Rahmen, einer Batterie verbunden werden können. Erfindungsgemäß sind die Batteriezellen somit bereits mit einer Halterung ausgebildet. So kann beispielsweise eine Maßnahme entfallen, bei der die Batteriezellen durch Anordnung mittels Abstandshaltern in vorgegebenen Positionen fixiert werden. Ferner können ansonsten üblicherweise verwendete bauliche Zwischenelemente, durch die Halterungsabschnitte, beispielsweise Befestigungsohren, (nachträglich) bereitgestellt werden und die dem eigentlichen Zellgehäuse, das heißt dem zum Lagern und zum Schutz der elektrochemischen Komponenten der Batteriezelle vorgesehenen Gehäuse, übergeordnet sind, entfallen. Dadurch kann insbesondere das Gewicht der Batterie verringert und demzufolge die spezifische Energie der Batteriezelle erhöht werden.An advantage of the invention is that the cell casings are designed such that they can be connected directly to a support structure, such as a frame, of a battery. According to the invention, the battery cells are thus already formed with a holder. Thus, for example, a measure can be omitted in which the battery cells are fixed by arrangement by means of spacers in predetermined positions. Furthermore, otherwise commonly used structural intermediate elements, by the support portions, such as mounting ears, (subsequently) are provided and the actual Cell housing, that is superordinate to the housing provided for storing and protecting the electrochemical components of the battery cell, omitted. As a result, in particular, the weight of the battery can be reduced and consequently the specific energy of the battery cell can be increased.
Die Erfindung ist nicht auf eine bestimmte Art von Batteriezellen beschränkt. So können insbesondere prismatisch geformte Batteriezellen oder zylindrisch geformte Batteriezellen die erfindungsgemäßen Zellgehäuse aufweisen. Ferner ist es aber auch denkbar, eine Coffee-Bag-Zelle gleich bei der Herstellung mit einem entsprechend gestalteten Halterungsabschnitt zu versehen.The invention is not limited to any particular type of battery cells. For example, prismatically shaped battery cells or cylindrically shaped battery cells can have the cell housings according to the invention. Furthermore, it is also conceivable to provide a coffee bag cell equal to the production with a correspondingly shaped mounting portion.
Bevorzugt wird das Zellgehäuse als Hardcase-Zellgehäuse gebildet. Dadurch kann eine besonders stabile Befestigung und Positionierung der Batteriezellen innerhalb einer Batterie erreicht werden. The cell housing is preferably formed as a hardcase cell housing. As a result, a particularly stable attachment and positioning of the battery cells within a battery can be achieved.
Gemäß einer Ausführungsform der Erfindung sind die Batteriezellen mit einem Zellgefäß, der sogenannten Zell-Can, und einem Zelldeckel, dem sogenannten Cap-Plate, ausgebildet.According to one embodiment of the invention, the battery cells are formed with a cell vessel, the so-called cell can, and a cell lid, the so-called cap plate.
Nach einer Weiterbildung der Erfindung ist dabei zumindest einer der Halterungsabschnitte an dem Zelldeckel angeordnet. Dadurch kann die Herstellung der erfindungsgemäßen Zellgehäuse besonders einfach erfolgen, indem lediglich die Form und/oder Größe der Zelldeckel entsprechend angepasst werden. According to a development of the invention, at least one of the support sections is arranged on the cell cover. As a result, the production of the cell housing according to the invention can be carried out particularly simply by merely adapting the shape and / or size of the cell cover accordingly.
Die Zelldeckel können mit dem Zellgefäß beispielsweise mittels Verschweißens oder durch Nanomolding verbunden werden.The cell lids can be connected to the cell vessel, for example by means of welding or by nanomolding.
Die mit den erfindungsgemäßen Zellgehäusen gebildeten Batteriezellen können an einer Haltestruktur eine Batterie befestigt sein, die beispielsweise eine Rahmenkonstruktion umfasst. Jedoch ist die Erfindung nicht auf eine Rahmenkonstruktion beschränkt. So können die Batteriezellen insbesondere auch mittels Befestigungsplatten verbunden werden.The battery cells formed with the cell housings according to the invention may be attached to a support structure of a battery, which comprises, for example, a frame construction. However, the invention is not limited to a frame construction. Thus, the battery cells can be connected in particular by means of mounting plates.
Bevorzugt umfasst die Rahmenkonstruktion ein Konstruktionsprofil, beispielsweise ein sogenanntes Boschprofil. Dadurch kann eine hohe Modularität auf günstige Weise erreicht werden. Dabei werden die Batteriezellen mithilfe ihrer Halterungsabschnitte mit der Rahmenkonstruktion der Haltestruktur verbunden, beispielsweise verschraubt. The frame construction preferably comprises a construction profile, for example a so-called Bosch profile. As a result, high modularity can be achieved in a favorable manner. In this case, the battery cells are connected by means of their support portions with the frame structure of the support structure, for example screwed.
Gemäß einer besonderen Ausführungsform der Erfindung ist die Haltestruktur zumindest teilweise aus Kunststoff gebildet oder mit Kunststoff beschichtet. Auch können die Zellgehäuse zumindest teilweise mit Kunststoff beschichtet oder mit Kunststoffteilen aufgebaut sein. Dadurch kann bei Einbau der Zellgehäuse beziehungsweise der Batteriezellen in eine Batterie eine hohe Packungsdichte der Batteriezellen bei gleichzeitig guter elektrischer Isolierung erreicht werden, und es kann vorteilhaft auf zusätzliche Isolationsmaterialien und Abstandshalter verzichtet werden. According to a particular embodiment of the invention, the support structure is at least partially formed of plastic or coated with plastic. The cell housing can also be at least partially coated with plastic or constructed with plastic parts. As a result, when the cell housing or the battery cells are installed in a battery, a high packing density of the battery cells can be achieved with simultaneously good electrical insulation, and advantageously additional insulation materials and spacers can be dispensed with.
Gemäß einer Ausführungsform der Erfindung ist die Mehrzahl von Batteriezellen sowie auch die Haltestruktur innerhalb der Batterie auf besondere Weise aufgeteilt. So können Batteriezellen in eine Mehrzahl von Batteriemodulen gruppiert werden, wobei die Haltestruktur dabei batteriemodulweise ausgebildet sein kann. Jedoch ist die Erfindung nicht auf eine solche Variante der mechanischen Ausbildung der Haltestruktur beschränkt. Auch kann die Haltestruktur je nach Untereinheit der Batterie jeweils mit separaten Rahmenkonstruktionen versehen sein, wodurch die Wartung und Handhabung der Batterie vereinfacht werden kann.According to one embodiment of the invention, the plurality of battery cells as well as the support structure within the battery is split in a special way. Thus, battery cells can be grouped into a plurality of battery modules, wherein the holding structure can be formed battery module. However, the invention is not limited to such a variant of the mechanical design of the support structure. Also, depending on the subunit of the battery, the support structure may each be provided with separate frame constructions, thereby simplifying maintenance and handling of the battery.
Bevorzugt weist die beanspruchte Batterie Lithium-Ionen-Batteriezellen auf. Jedoch ist die Erfindung nicht auf die Lithium-Ionen-Batteriezellen beschränkt. So betrifft die Erfindung gemäß anderen speziellen Ausführungsformen auch Zellgehäuse von Batteriezellen mit anderen Chemiesystemen, wie zum Beispiel Nickel-Metall-Hydrid-Zellen oder Lithium-Metall-Polymer-Zellen. The claimed battery preferably has lithium-ion battery cells. However, the invention is not limited to the lithium-ion battery cells. Thus, according to other specific embodiments, the invention also relates to cell housings of battery cells with other chemical systems, such as, for example, nickel metal hydride cells or lithium metal polymer cells.
Nach einem Aspekt der Erfindung wird auch ein Fahrzeug, insbesondere ein Hybrid- oder Elektrofahrzeug, zur Verfügung gestellt, das die erfindungsgemäße Batterie zur Versorgung eines Elektromotors des Fahrzeugs umfasst.According to one aspect of the invention, a vehicle, in particular a hybrid or electric vehicle, is provided, which comprises the battery according to the invention for supplying an electric motor of the vehicle.
