Description
Die Erfindung betrifft eine Batterie aus einer Vielzahl von im Wesentlichen prismatischen Batterieeinzelzellen nach der im Oberbegriff von Anspruch 1 näher definierten Art.The invention relates to a battery made up of a large number of essentially prismatic individual battery cells of the type defined in more detail in the preamble of
Batterien, welche sich aus einer Vielzahl von Batterieeinzelzellen aufbauen, sind aus dem Stand der Technik bekannt. Insbesondere Hochleistungs- oder Hochvoltbatterien, wie sie beispielsweise als Traktionsbatterien in zumindest teilweise elektrisch angetriebenen Fahrzeugen eingesetzt werden, haben typischerweise einen derartigen Aufbau. Die Batterieeinzelzellen sind dabei häufig prismatisch ausgebildet und werden zu einem Stapel aufgestapelt. Die Batterieeinzelzellen können in verschiedenen Technologien realisiert sein, wobei für die Anwendung als Traktionsbatterien insbesondere die Lithiumlonen-Technologie von großem Interesse ist.Batteries which are made up of a large number of individual battery cells are known from the prior art. In particular, high-performance or high-voltage batteries, such as those used as traction batteries in at least partially electrically powered vehicles, typically have such a structure. The individual battery cells are often prismatic and are stacked in a stack. The individual battery cells can be implemented using various technologies, with lithium-ion technology being of particular interest for use as traction batteries.
Aus der
Aus dem weiteren allgemeinen Stand der Technik ist es nun ferner bekannt, dass Batterieeinzelzellen in Hochleistungs- bzw. Hochvoltbatterien beim Laden und Entladen eine große Abwärme entwickeln und daher gekühlt und in speziellen Situationen, beispielsweise bei einem Start unter sehr niedrigen Umgebungstemperaturen, auch erwärmt werden müssen. Für eine solche Heizung oder Kühlung kann dabei insbesondere eine Kühleinrichtung vorgesehen sein, welche von einem entsprechend temperierten Gas und/oder einer speziell temperierten Flüssigkeit durchströmt wird, um die Zellen im Normalfall zu kühlen und unter besonderen Betriebsbedingungen gegebenenfalls auch zu erwärmen.It is now also known from the further general state of the art that individual battery cells in high-performance or high-voltage batteries develop a large amount of waste heat during charging and discharging and therefore have to be cooled and also heated in special situations, for example when starting at very low ambient temperatures . For such heating or cooling, a cooling device can be provided in particular, through which an appropriately tempered gas and/or a specially tempered liquid flows in order to normally cool the cells and, under special operating conditions, possibly also to heat them.
Um eine besonders effiziente Kühlung zu realisieren, ist es insbesondere aus der
Die Aufgabe der hier vorliegenden Erfindung besteht nun darin, eine Batterie mit einer Vielzahl von Batterieeinzelzellen anzugeben, welche diese Nachteile vermeidet und einen einfachen Aufbau der Batterie gewährleistet.The object of the present invention consists in specifying a battery with a multiplicity of individual battery cells which avoids these disadvantages and ensures a simple construction of the battery.
Erfindungsgemäß wird diese Aufgabe durch eine Batterie mit den Merkmalen im kennzeichnenden Teil des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen und Ausgestaltungen der erfindungsgemäßen Batterie ergeben sich aus den abhängigen Unteransprüchen.According to the invention, this object is achieved by a battery having the features in the characterizing part of
Die erfindungsgemäße Lösung sieht es vor, dass die Niedervoltanschlusselemente in Form von Kontaktfahnen ausgebildet sind, welche zwischen der Kühleinrichtung und dem Zwischenrahmen mit den verbundenen Ableiterfahnen der Batterieeinzelzellen verbunden ist. Eine solche Ausgestaltung der Niedervoltanschlüsse für die Batterieelektronik in Form von Kontaktfahnen, welche zwischen der Kühleinrichtung und den verbundenen Ableiterfahnen mit diesen verbunden sind, ist besonders einfach und effizient im Aufbau. Die verbundenen Ableiterfahnen werden mit der Batterieelektronik bzw. der mit den Kontaktfahnen verbundenen Platine, welche die Batterieelektronik aufweist oder welche mit dieser verbunden ist, in Kontakt gebracht. Dies kann beispielsweise durch ein Verpressen der verbundenen Ableiterfahnen und der Kontaktfahnen durch die Kühleinrichtung erfolgen. Insbesondere können diese drei Teilelemente auch untereinander verschweißt ausgebildet sein, was vorzugsweise bei der Herstellung in einem einzigen Schritt erfolgt. Die Niedervoltanschlüsse werden so einfach und effizient, ohne den Aufbau der Batterie insgesamt zu stören, modifizierte Zwischenrahmen zu benötigen und bei der Montage einen übermäßigen Aufwand zu verursachen, direkt mit den Batterieeinzelzellen verbunden.The solution according to the invention provides that the low-voltage connection elements are designed in the form of contact lugs, which are connected between the cooling device and the intermediate frame with the connected conductor lugs of the individual battery cells. Such a configuration of the low-voltage connections for the battery electronics in the form of contact lugs, which are connected between the cooling device and the connected conductor lugs, is particularly simple and efficient in construction. The connected conductor lugs are brought into contact with the battery electronics or with the circuit board connected to the contact lugs, which has the battery electronics or which is connected to it. This can for example wise by pressing the connected conductor lugs and the contact lugs through the cooling device. In particular, these three partial elements can also be welded to one another, which preferably takes place in a single step during production. The low-voltage connections are connected directly to the individual battery cells in a simple and efficient manner, without disturbing the structure of the battery as a whole, requiring modified intermediate frames and causing excessive effort during assembly.
Vorzugsweise kann es dabei vorgesehen sein, dass wenigstens eine der Ableiterfahnen und/oder ein elektrisches Verbindungselement, welches die Ableiterfahnen untereinander verbindet, eine Ausnahme für die Kontaktfahne aufweist. Über eine solche Ausnahme, beispielsweise eine eingeprägte Vertiefung oder eine Ausklinkung in einer von zwei sich überlappenden Ableiterfahnen, kann Platz für die Kontaktfahne geschaffen werden, insbesondere wenn diese eine vergleichbare Materialstärke aufweist wie die Tiefe der Ausnehmung. Ohne dass die Kontaktfahne über die verbundenen Ableiterfahnen und/oder deren elektrisches Verbindungselement wesentlich übersteht, kann dann einfach die Kühleinrichtung aufgebracht und mit den verbundenen Ableiterfahnen in an sich bekannter Art und Weise mit dazwischen angeordneter Wärmeleitfolie verpresst werden.It can preferably be provided that at least one of the conductor lugs and/or an electrical connecting element, which connects the conductor lugs to one another, has an exception for the contact lug. Such an exception, for example an embossed indentation or a notch in one of two overlapping conductor lugs, can create space for the contact lug, particularly if the latter has a material thickness comparable to the depth of the recess. Without the contact lug protruding significantly beyond the connected collector lugs and/or their electrical connection element, the cooling device can then simply be applied and pressed with the connected collector lugs in a manner known per se with a thermally conductive foil arranged in between.
In einer weiteren sehr günstigen Ausgestaltung der erfindungsgemäßen Batterie kann es außerdem vorgesehen sein, dass die Ableiterfahnen in Stapelrichtung abgekantet ausgebildet sind, wobei der Stapel der Batterieeinzelzellen zwei Reihen von verbundenen Ableiterfahnen aufweist, zwischen welchen die Platine angeordnet ist. Ein solcher Aufbau, bei dem die Platine zwischen zwei Reihen von Ableiterfahnen angeordnet ist, ist besonders einfach und effizient in der Herstellung. Auf jede der Ableiterfahnen kann dann gemäß einer vorteilhaften Weiterbildung der erfindungsgemäßen Batterie eine eigene Kühleinrichtung aufgebracht werden, wobei die Kontaktfahnen die Platine zwischen der Kühleinrichtung und den miteinander verbundenen Ableiterfahnen kontaktieren und eine Niedervoltverbindung zur Platine herstellen. Die Platine kann dann entweder selbst die Batterieelektronik aufweisen oder beispielsweise über Kabel oder dergleichen mit einer solchen Batterieelektronik verbunden sein.In a further very favorable embodiment of the battery according to the invention, it can also be provided that the collector lugs are folded in the stacking direction, with the stack of individual battery cells having two rows of connected collector lugs between which the circuit board is arranged. Such a structure, in which the circuit board is arranged between two rows of conductor lugs, is particularly simple and efficient to manufacture. According to an advantageous development of the battery according to the invention, each of the conductor lugs can then have its own cooling device applied to it, with the contact lugs contacting the circuit board between the cooling device and the conductor lugs connected to one another and producing a low-voltage connection to the circuit board. The circuit board can then either have the battery electronics itself or be connected to such battery electronics, for example, via cables or the like.
Weitere vorteilhafte Ausgestaltungen der erfindungsgemäßen Batterie ergeben sich aus den restlichen Unteransprüchen und werden anhand der Ausführungsbeispiele deutlich, welche nachfolgend unter Bezugnahme auf die Figuren näher beschrieben sind.Further advantageous configurations of the battery according to the invention result from the remaining subclaims and become clear from the exemplary embodiments, which are described in more detail below with reference to the figures.
