Abstract
Description
Die Erfindung betrifft ein Verfahren sowie eine Vorrichtung zur Brandprävention und/oder -bekämpfung für eine Li-Ionen Batterie eines Fahrzeuges, insbesondere eines Kraftfahrzeuges, nach dem Oberbegriff des Anspruchs 1 bzw. nach dem Oberbegriff des Anspruchs 20, wie beides in der Automobilindustrie verwendet und hier als bekannt unterstellt wird.The The invention relates to a method and a device for fire prevention and / or combat for a Li-ion battery a vehicle, in particular a motor vehicle, according to the preamble of claim 1 or according to the preamble of claim 20, such as both used in the automotive industry and known here is assumed.
Li-Ionen-Hochvolt-Batterien für Fahrzeuganwendungen bestehen aus vielen in Reihe und/oder parallel geschalteten Einzelzellen, die sich mit der dazugehörenden Elektronik und Kühlung in einem gemeinsamen Gehäuse befinden. Die Li-Ion-Einzelzellen müssen gekühlt werden, um die entstehende Verlustwärme abzuführen. Eine Möglichkeit zur Kühlung der Einzelzellen ist die Verwendung eines am oder im Zellblock angeordneten Kühlers bzw. einer Kälteplatte, die über einen Wärmetauscher indirekt mit dem Kältemittel des Fahrzeug-Kältekreislaufs wärmeleitend verbunden ist.Li-ion high-voltage batteries for vehicle applications consist of many in series and / or in parallel switched single cells, which are associated with the Electronics and cooling in a common housing are located. The Li-Ion single cells must be cooled be used to dissipate the resulting heat loss. A way to cool the single cells is the use of a cooler located on or in the cell block or a cold plate, via a heat exchanger indirectly thermally conductive with the refrigerant of the vehicle refrigeration cycle connected is.
Bei Li-Ionen-Zellen können bei Überladung oder Kurzschluss die Temperatur und der Innendruck im Gehäuse stark ansteigen. Die in den Zellen enthaltene elektrochemisch aktive Masse kann thermische Instabilität aufweisen. Insbesondere das in Li-Ionen-Zellen befindliche Nickeloxid kann sich oberhalb von 150°C irreversibel in einer exothermen Reaktion zersetzen. Dadurch kann sich die Zelle weiter erwärmen und der Druck in ihrem Inneren ansteigen bis zum definierten und bestimmungsgemäßen Öffnen der im Zellgehäuse eingebrachten Druckbegrenzungselemente, welche z. B. durch eine gezielte Schwächung des Batteriegehäuses ausgebildet sind (Sollbruchstelle). Beim Ausströmen der heißen Gase bedarf es Maßnahmen, dass sich Teile des Batterieinnenlebens nicht entzünden können. Als Auslöser von Batteriebränden werden in der Literatur vereinzelt Kurzschlüsse in deren elektrischen Teil genannt. Durch diese Phänomene könnten sich weitere Zellen überhitzen und der Zerstörungsprozess wird insbesondere selbsttätig weitergeführt.at Li-ion cells may overcharge or short circuit the temperature and the internal pressure in the housing rise sharply. The electrochemically active material contained in the cells can be thermal Have instability. Especially in Li-ion cells located nickel oxide can be irreversible above 150 ° C. decompose in an exothermic reaction. This can cause the cell continue to heat up and the pressure inside them rise until defined and intended opening the pressure limiting elements introduced in the cell housing, which z. B. by a targeted weakening of the battery case are formed (predetermined breaking point). When flowing out of Hot gases require action that parts battery life can not ignite. As a trigger of battery fires are in the Literature isolated short circuits in their electrical Part called. By these phenomena could themselves more cells overheat and the destruction process in particular will be continued automatically.
Derzeit sind keine auf diesen speziellen Anwendungsfall konzipierten Feuerlöschsysteme bekannt. Aus der Gebäudetechnik bekannte Sprinkleranlagen sind insbesondere ungeeignet, da diese über eine im Einsatzfall berstende Glasampulle verfügen, die bei im Fahrzeug vorliegenden Vibrationen und/oder Stößen zerbrechen und dadurch das Feuerlöschsystem auslösen könnten.Currently are not fire extinguishing systems designed for this specific application known. From the building engineering known sprinkler systems are in particular unsuitable, since these over a case of use Have bursting glass ampule, which is present in the vehicle Vibrations and / or shocks break and thereby could trigger the fire extinguishing system.
