Abstract
Description
Die vorliegende Erfindung betrifft eine Batterie für ein Kraftfahrzeug, im Einzelnen gemäß dem Oberbegriff von Anspruch 1, sowie ein Verfahren zum Löschen oder Verhindern eines Batteriebrandes in einer solchen Batterie.The present invention relates to a battery for a motor vehicle, in more detail according to the preamble of
Batterien für ein Kraftfahrzeug der gattungsgemäßen Art, die beispielsweise als Traktionsbatterien eingesetzt werden, das heißt bei einem Elektrofahrzeug oder Hybridfahrzeug elektrische Leistung für eine elektrische Antriebsmaschine liefern, weisen in der Regel eine Vielzahl von Batterieeinzelzellen in einem Gehäuse auf, die zu einem Stapel zusammengefügt und miteinander elektrisch kontaktiert sind. Die Batterieeinzelzellen müssen im Betrieb gekühlt werden, um die entstehende Verlustwärme abzuführen.Batteries for a motor vehicle of the generic type, which are used for example as traction batteries, that is to supply electrical power for an electric drive machine in an electric vehicle or hybrid vehicle, usually have a plurality of battery cells in a housing, which are assembled into a stack and each other electrically contacted. The battery cells must be cooled during operation to dissipate the resulting heat loss.
Zur Kühlung ist ein Kühlkreislauf vorgesehen, der die Verlustwärme aus dem Inneren des Gehäuses mittels eines Kühlmediums abtransportiert.For cooling, a cooling circuit is provided, which removes the heat loss from the interior of the housing by means of a cooling medium.
Wenn eine solche Batterie in Brand gerät, erschwert das geschlossene Gehäuse ein Löschen der Batterie. Wenn die Batterie ferner als Lithium-Ionen-Batterie ausgeführt ist, besteht die Gefahr einer exothermen Reaktion, die ohne massives Kühlen nicht gestoppt werden kann. Herkömmlich werden daher üblicherweise am Gehäuse der Batterie neben den Anschlüssen des Kühlkreislaufes separate Spülanschlüsse vorgesehen, die von außen zugänglich sind. Durch diese Spülanschlüsse kann eine große Menge eines Löschmittels, beispielsweise Wasser oder CO2 gepumpt werden, um die Temperatur im Inneren des Gehäuses abzusenken. Solche separaten Spülanschlüsse werden auch als Löschmittelanschlüsse bezeichnet.When such a battery burns, the closed case makes it difficult to extinguish the battery. Further, if the battery is a lithium-ion battery, there is a danger of an exothermic reaction that can not be stopped without massive cooling. Conventionally, therefore, separate flushing connections are usually provided on the housing of the battery in addition to the connections of the cooling circuit, which are accessible from the outside. Through these purge ports, a large amount of an extinguishing agent, such as water or CO 2 can be pumped to lower the temperature inside the housing. Such separate purge ports are also referred to as extinguishant ports.
Die zusätzlichen Anschlüsse benötigen Bauraum, erhöhen das Batteriegewicht und verursachen Kosten. Insbesondere bei Traktionsbatterien, die im Fahrzeug verbaut sind, müssen die Anschlüsse mit weiteren Leitungen so durch das Fahrzeug geführt werden, dass diese im Brandfall zugänglich sind, ohne dass das Fahrzeug demontiert werden muss.The additional connections require installation space, increase the battery weight and cause costs. Especially with traction batteries that are installed in the vehicle, the connections must be conducted with other lines through the vehicle so that they are accessible in case of fire, without the vehicle must be dismantled.
Die Offenlegungsschrift
Problematisch bei der vorgeschlagenen Lösung ist jedoch, dass mitunter im Kühlkreislauf nicht ausreichend viel CO2 zur Verfügung steht, um sämtlichen Sauerstoff aus dem Innenraum des Gehäuses zu verdrängen, und dass die Kühlung des Innenraums zu gering ist, um einen unerwünschten Temperaturanstieg zu vermeiden.The problem with the proposed solution, however, is that sometimes insufficient CO 2 is available in the cooling circuit to displace all oxygen from the interior of the housing, and that the cooling of the interior is too small to avoid an undesirable increase in temperature.
Die europäische Patentschrift
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Batterie für ein Kraftfahrzeug der eingangs dargestellten Art anzugeben, die im Brandfall oder bei Gefahr eines Brandes schnell und stark gekühlt werden kann, ohne den notwendigen Bauraum, das Gewicht und die Kosten wesentlich zu erhöhen. Ferner soll ein Verfahren zum Löschen oder Verhindern eines Batteriebrandes einer solchen Batterie angegeben werden.The present invention has for its object to provide a battery for a motor vehicle of the type described above, which can be quickly and strongly cooled in the event of fire or danger of fire, without increasing the necessary space, weight and cost significantly. Furthermore, a method for canceling or preventing a battery burn of such a battery is to be specified.
Die erfindungsgemäße Aufgabe wird durch eine Batterie mit den Merkmalen von Anspruch 1 und ein Verfahren mit den Merkmalen von Anspruch 7 gelöst. In den abhängigen Ansprüchen sind vorteilhafte und besonders zweckmäßige Ausgestaltungen der Erfindung angegeben.The object of the invention is achieved by a battery having the features of
Im Einzelnen weist eine erfindungsgemäße Batterie für ein Kraftfahrzeug, die insbesondere als Lithium-Ionen-Batterie ausgeführt ist, ein Gehäuse auf, das zumindest eine, in der Regel jedoch eine Vielzahl von Batterieeinzelzellen in einem Innenraum des Gehäuses umgibt. Das Gehäuse ist insbesondere gegenüber der Umgebung abgedichtet ausgeführt.In detail, a battery according to the invention for a motor vehicle, which is designed in particular as a lithium-ion battery, a housing which surrounds at least one, but usually a plurality of individual battery cells in an interior of the housing. The housing is designed in particular sealed from the environment.
Zur Kühlung der Batterie bzw. des Innenraums des Gehäuses ist ein Kühlkreislauf vorgesehen, in dem ein Kühlmedium zirkuliert, wobei der Kühlkreislauf einen innerhalb des Gehäuses verlaufenden inneren Kreislaufzweig und einen mit diesem zur Kreislaufführung des Kühlmediums verbundenen äußeren Kreislaufzweig außerhalb des Gehäuses aufweist. Beispielsweise weist der äußere Kreislaufzweig einen Vorlauf auf, über welchem verhältnismäßig kaltes Kühlmedium in den inneren Kreislaufzweig geführt wird. Im inneren Kreislaufzweig nimmt das Kühlmedium Wärme aus dem Innenraum des Gehäuses von den Batterieeinzelzellen auf und kann dann über einen Rücklauf des äußeren Kreislaufzweigs, der ebenfalls am inneren Kreislaufzweig angeschlossen ist, wieder aus dem Gehäuse herausgeführt werden und geeignet abgekühlt werden, beispielsweise mittels eines Wärmetauschers im äußeren Kreislaufzweig.For cooling the battery or the interior of the housing, a cooling circuit is provided, in which a cooling medium circulates, wherein the cooling circuit has a running inside the housing inner circulation branch and connected thereto for the circulation of the cooling medium outer circulation branch outside of the housing. For example, the outer one Circulation branch to a flow, over which relatively cold cooling medium is fed into the inner cycle branch. In the inner cycle branch, the cooling medium absorbs heat from the interior of the housing of the battery cells and can then be led out of the housing via a return of the outer circuit branch, which is also connected to the inner cycle branch and suitably cooled, for example by means of a heat exchanger in outer circuit branch.
Der Kühlkreislauf und damit auch der innere Kreislaufzweig ist gegenüber dem Innenraum des Gehäuses kühlmediumdicht abgetrennt, wobei wenigstens ein oberhalb einer vorgegebenen Temperatur selbsttätig öffnendes Verschlusselement innerhalb des Gehäuses vorgesehen ist, das den Innenraum von dem Kühlmedium des Kühlkreislaufes, nämlich des inneren Kreislaufzweigs trennt. Wenn somit eine unzulässig hohe Temperatur im Innenraum des Gehäuses entsteht, öffnet das Verschlusselement selbsttätig und lässt Kühlmedium aus dem inneren Kreislaufzweig in den Innenraum einströmen, um diesen zu kühlen und vorteilhaft Sauerstoff zu verdrängen.The cooling circuit and thus also the inner circulation branch is separated from the interior of the housing in a manner of cooling medium, at least one closure element which automatically opens above a predetermined temperature being provided inside the housing, which separates the interior space from the cooling medium of the cooling circuit, namely the inner circulation branch. Thus, if an inadmissibly high temperature arises in the interior of the housing, the closure element opens automatically and allows cooling medium from the inner cycle branch to flow into the interior to cool it and advantageously displace oxygen.
Erfindungsgemäß ist nun am äußeren Kreislaufzweig des Kühlkreislaufes wenigstens ein Löschmittelanschluss vorgesehen. Über diesen Löschmittelanschluss am äußeren Kreislaufzweig des Kühlkreislaufes kann in kurzer Zeit im Falle eines Batteriebrandes oder drohenden Batteriebrandes Kühlmedium oder ein Löschmedium, beispielsweise Löschwasser oder CO2, über den äußeren Kreislaufzweig zum inneren Kreislaufzweig und dort weiter, nämlich über das offene Verschlusselement, in den Innenraum des Gehäuses geleitet werden. Selbstverständlich ist eine solche Einleitung von Kühlmedium oder Löschmittel auch im Notfall bereits dann möglich, wenn das Verschlusselement im Inneren des Gehäuses noch nicht geöffnet wurde.According to the invention, at least one extinguishing agent connection is now provided on the outer circulation branch of the cooling circuit. About this extinguishing agent connection at the outer cycle branch of the cooling circuit can in a short time in the case of a battery fire or imminent battery fire cooling medium or a quenching medium, such as fire water or CO 2 , on the outer cycle branch to the inner cycle branch and there on, namely on the open closure element in the interior of the housing. Of course, such an introduction of cooling medium or extinguishing agent even in an emergency already possible if the closure element inside the housing has not been opened.
Durch die erfindungsgemäße Ausgestaltung können Batteriebrände schnell und sicher gelöscht werden, ohne dass zusätzliche Spülanschlüsse am Gehäuse der Batterie notwendig sind. Da der äußere Kreislaufzweig in einem Fahrzeug an vielen verschiedenen Stellen leicht zugänglich ist, kann der Löschmittelanschluss oder eine Vielzahl von Löschmittelanschlüssen relativ frei platziert werden.The inventive design battery fires can be deleted quickly and safely, without additional flushing connections on the housing of the battery are necessary. Since the outer cycle branch is easily accessible in a vehicle in many different places, the extinguishing agent connection or a plurality of extinguishing agent connections can be placed relatively freely.
Besonders günstig ist es, wenn die Kühlmediumleitungen des inneren Kreislaufzweigs innerhalb des Gehäuses der Batterie derart ausgelegt sind, dass sie im Fall eines Batteriebrandes zerstört werden. Der restliche Kühlkreislauf außerhalb des Gehäuses der Batterie hingegen ist temperaturbeständig ausgelegt, um die Zufuhr von zusätzlichem Kühlmedium oder von Löschmittel in den Innenraum des Gehäuses der Batterie sicher zu ermöglichen. Beispielsweise kann die Wandung des inneren Kreislaufzweigs als Berst- und/oder Schmelzstruktur ausgeführt sein, um das selbsttätig öffnende Verschlusselement auszubilden, wobei sich die Wandung mit dieser Berst- und/oder Schmelzstruktur entlang und/oder durch die eine oder Vielzahl von Batterieeinzelzellen erstreckt.It is particularly favorable if the cooling medium lines of the inner circulation branch are designed within the housing of the battery in such a way that they are destroyed in the event of a battery fire. The remaining cooling circuit outside the housing of the battery, however, is designed to be temperature-resistant, to allow the supply of additional cooling medium or extinguishing agent in the interior of the housing of the battery safely. For example, the wall of the inner cycle branch may be configured as a bursting and / or melting structure to form the self-opening closure element, wherein the wall extends with this bursting and / or melt structure along and / or through the one or a plurality of battery individual cells.
Die Batterieeinzelzellen weisen gemäß einer vorteilhaften Ausgestaltung jeweils einen in Folie eingeschweißten Elektrodenstapel auf und sind zu einem Stapel innerhalb des Gehäuses der Batterie zusammengefügt und elektrisch miteinander kontaktiert, entweder in einer Reihenschaltung oder in einer Parallelschaltung.According to an advantageous embodiment, the individual battery cells each have an electrode stack welded into foil and are joined together to form a stack within the housing of the battery and are electrically connected to one another, either in series connection or in parallel connection.
Wenn der externe Kreislaufzweig einen Vorlauf und einen Rücklauf aufweist, so können beide zum gleichzeitigen Zuführen des Löschmittels, das auch zusätzliches Kühlmedium sein kann, in den Innenraum des Gehäuses genutzt werden.If the external circuit branch has a flow and a return, both can be used for simultaneously supplying the extinguishing agent, which may also be additional cooling medium, into the interior of the housing.
Das Gehäuse der Batterie selbst kann eine Druckentlastungseinrichtung, beispielsweise in Form einer Druckentlastungsklappe oder eines Überdruckventils, aufweisen, die oberhalb eines vorgegebenen Druckes öffnet, um Überdruck und/oder Löschmittel bzw. Kühlmedium aus dem Batteriegehäuse entweichen zu lassen.The housing of the battery itself may have a pressure relief device, for example in the form of a pressure relief valve or a pressure relief valve, which opens above a predetermined pressure to allow excess pressure and / or extinguishing agent or cooling medium to escape from the battery housing.
Die Erfindung soll nachfolgend anhand eines Ausführungsbeispiels und der Figur exemplarisch beschrieben werden.The invention will be described below by way of example with reference to an embodiment and the figure.
