Aus dem Stand der Technik sind verschiedene Verfahren und Vorrichtungen zur Kühlung bekannt. Dabei kann es sich beispielsweise um eine indirekte Kühlung mittels Einbindung der Batterie in einen Klimakreislauf oder eine direkte Kühlung der Einzelzellen mittels vorgekühlter Luft, die zwischen die Zellen geleitet wird, handeln.batteries for vehicle applications, especially for hybrid applications, consist of several series and / or parallel single cells, which are usually associated with electronics and Devices for cooling in a common battery case are located. From the prior art are various methods and devices for cooling known. It can be for example, an indirect cooling by means of integration the battery in an air conditioning circuit or a direct cooling the single cells by means of pre-cooled air, the between the cells are passed, act.

Nachteilig ist, dass mittels der Luft zur Kühlung der Einzelzellen Feuchtigkeit in das Batteriegehäuse eindringen kann, welche eine Korrosion aller metallischen Bauteile und dadurch verursachte Kurzschlüsse bewirken kann. Auch mittels der Luft transportierte Fremdstoffe wie Staub können zu einer Verschmutzung des Batterieinnenlebens führen, welche wiederum Kurzschlüsse oder Kriechströme aufgrund von Isolationsschwächen hervorrufen können. Nachteilig ist weiterhin, dass sich bei einer Überladung oder einem Kurzschluss die Einzelzellen öffnen, so ein Fahrzeuginnenraum von austretenden Gasen beispielsweise durch schnell schließende Klappen abgeschirmt sein muss, deren Funktion z. B. bei einem Fahrzeugcrash nicht sichergestellt ist.adversely is that using the air to cool the individual cells Moisture can enter the battery case, which Corrosion of all metallic components and thereby caused Cause short circuits. Also transported by air Foreign matter such as dust can lead to pollution of the Internal battery life lead, which in turn short circuits or leakage currents due to insulation weaknesses can cause. Another disadvantage is that open the single cells in the event of an overload or a short circuit, such a vehicle interior of escaping gases, for example fast-closing flaps must be shielded, whose Function z. B. is not ensured in a vehicle crash.

Dadurch kann wiederum die Gefahr von Kriechströmen und Kurzschlüssen gesenkt werden. Ferner ist durch die dichte Ausführung des Batteriegehäuses neben der Abschirmung der Komponenten von der Kühlluft auch eine Verminderung einer Gefahr eines Eindringens von austretenden Gasen in einen Fahrzeuginnenraum, insbesondere bei sich öffnenden Einzelzellen, realisierbar.at the battery according to the invention with several in a battery housing and electrically parallel and / or serially interconnected single cells according to the invention in the Battery housing arranged an air guide, which is designed as a media-tight closed hollow body.
