Description
Die Erfindung betrifft eine Batterie gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a battery according to the preamble of
Hochvolt-Batterien für Fahrzeuganwendungen bestehen aus einer Anzahl elektrisch seriell und/oder parallel geschalteten Einzelzellen, die sich mit der dazugehörenden Elektronik und Kühlung in einem gemeinsamen Gehäuse befinden. Die Einzelzellen sind in so genannten Zellblöcken zusammengefasst, die jeweils eine Mehrzahl von Einzelzellen inklusive deren mechanischer Fixierung, Kontaktierung und Einrichtungen zur Temperierung umfassen.High-voltage batteries for vehicle applications consist of a number of electrically series and / or parallel-connected single cells, which are located with the associated electronics and cooling in a common housing. The individual cells are combined in so-called cell blocks, each comprising a plurality of individual cells including their mechanical fixation, contacting and temperature control devices.
Bei rechteckig ausgebildeten Einzelzellen, wie beispielsweise sogenannten Pouchzellen oder prismatische Hardcasezellen, werden zur Bildung eines Zellblocks diese mittels Halteelementen fixiert, die entweder zwischen den Einzelzellen angeordnet sind oder diese jeweils umschließen, wobei ein Halteelement dazu in Schalenform beziehungsweise in Rahmenform ausgebildet ist. Die mechanische Fixierung der Zellen erfolgt im Wesentlichen kraftschlüssig durch Reibung zwischen den Halteelementen und den Einzelzellen, wenn der Zellblock über Spannelemente, z. B. Zuganker, Gewindestangen, Schrauben, Spannbänder, und Druckplatten verpresst wird. Als Rundzellen ausgebildete Einzelzellen werden üblicherweise in Gestellen fixiert.In the case of rectangular individual cells, such as, for example, so-called pouch cells or prismatic hardcase cells, these are fixed by means of holding elements, which are either arranged between the individual cells or enclose these, in each case forming a cell block, wherein a holding element is designed in shell form or in frame form. The mechanical fixation of the cells is substantially non-positively by friction between the holding elements and the individual cells when the cell block via clamping elements, for. As tie rods, threaded rods, screws, straps, and pressure plates is pressed. Single cells designed as round cells are usually fixed in racks.
Die einer Vorspannung des Zellblocks dienenden Komponenten, wie Druckplatten und Spannelemente, Haltegestelle für die Einzelzellen sowie Kühlplatten sind zumindest teilweise aus Metall ausgeführt und sind aufgrund der Befestigung im Batteriegehäuse mit einem elektrischen Massepotential verbunden. Das Batteriegehäuse ist aus Festigkeits- und Sicherheitsgründen sowie aus Gründen der elektromagnetischen Verträglichkeit ebenfalls im Wesentlichen aus Metall gebildet. Weiterhin ist ein Kühlmittel der Batterie, z. B. Wasser, Kältemittel der Fahrzeugklimaanlage, welches in der Regel elektrisch leitfähig ist, ebenfalls mit einem elektrischen Massepotential verbunden.The components of a bias of the cell block serving as printing plates and clamping elements, holding frames for the individual cells and cooling plates are at least partially made of metal and are connected due to the attachment in the battery case with an electrical ground potential. The battery case is also made essentially of metal for strength and safety reasons and for reasons of electromagnetic compatibility. Furthermore, a coolant of the battery, for. As water, refrigerant the vehicle air conditioning system, which is usually electrically conductive, also connected to an electrical ground potential.
Der Erfindung liegt die Aufgabe zu Grunde, eine gegenüber dem Stand der Technik verbesserte Batterie anzugeben.The invention is based on the object to provide a comparison with the prior art improved battery.
Die Aufgabe wird erfindungsgemäß durch eine Batterie mit den in Anspruch 1 angegebenen Merkmalen gelöst.The object is achieved by a battery having the features specified in
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Eine Batterie mit einem Batteriegehäuse umfasst eine Anzahl elektrisch in Reihe und/oder parallel verschalteter Einzelzellen. Erfindungsgemäß sind die Einzelzellen in mehreren elektrisch voneinander isolierten Zellblöcken angeordnet und mittels einer aus einem elektrisch isolierenden Material gebildeten Haltevorrichtung gemeinsam mit dem Batteriegehäuse kraft- und/oder form- und/oder stoffschlüssig verbindbar.A battery with a battery housing comprises a number of individual cells electrically connected in series and / or in parallel. According to the invention, the individual cells are arranged in a plurality of cell blocks which are electrically insulated from one another and can be positively and / or positively and / or materially connected to the battery housing by means of a retaining device formed from an electrically insulating material.
Durch die Aufteilung der Einzelzellen in mehrere Zellblöcke und einer Befestigung dieser an einer gemeinsamen elektrisch isolierenden Haltevorrichtung, ist es möglich, eine bauraumsparende elektrische Isolierung der spannungsführenden Komponenten einer Batterie, d. h. die Pole der Einzelzellen, die Zellverbinder, die Gehäuse der Einzelzellen und die Temperiervorrichtung, von einem elektrischen Massepotential zu realisieren. Dies ist insbesondere bei Batterien mit vergleichsweise hohen Spannungslagen von Vorteil, welche einen erhöhten Bauraum- und Materialbedarf zur Realisierung der elektrischen Isolierung der spannungsführenden Komponenten von dem Massepotential benötigen. Weiterhin sind mittels der gemeinsamen Haltevorrichtung die spannungsführenden Komponenten der Zellblöcke voneinander elektrisch isoliert.By dividing the individual cells into several cell blocks and attaching them to a common electrically insulating holding device, it is possible to save a space-saving electrical insulation of the live components of a battery, d. H. the poles of the individual cells, the cell connectors, the housing of the individual cells and the tempering, to realize an electrical ground potential. This is particularly advantageous in batteries with relatively high voltage levels, which require increased space and material requirements for realizing the electrical insulation of the live components of the ground potential. Furthermore, by means of the common holding device, the live components of the cell blocks are electrically isolated from each other.
