Description
Die vorliegende Erfindung betrifft ein Gehäuse zur Aufnahme einer Vielzahl von Bleiakkumulatoren.The present invention relates to a housing for accommodating a plurality of lead-acid batteries.
Bleiakkumulatoren werden häufig für Antriebszwecke, zur Notstromversorgung und für das Starten von Verbrennungsmotoren in Kraftfahrzeugen verwendet. In jüngster Zeit werden Bleiakkumulatoren aber auch als Energiespeicher zur Speicherung regenerativ erzeugter Energien eingesetzt. So wird beispielsweise die von einer Solaranlage erzeugte Energie in Bleiakkumulatoren zwischengespeichert, aus denen sie bei Bedarf zu einem späteren Zeitpunkt entnommen werden kann. Problematisch ist jedoch, dass beim Betrieb von Bleiakkumulatoren bei einer Spannung von etwa 2,23 Volt Knallgas entstehen kann. Da Knallgas eine detonationsfähige Mischung aus gasförmigem Wasserstoff und Sauerstoff darstellt, ist der Betrieb von Bleiakkumulatoren in geschlossenen Räumen nicht völlig gefahrlos. Zwar würde eine entsprechend eingerichtete Belüftung in solchen Räumen diese Gefahr weitestgehend vermeiden. Die Installation einer Belüftungsanlage ist jedoch nicht immer möglich oder sehr aufwendig.Lead-acid batteries are frequently used for drive purposes, for emergency power supply and for starting internal combustion engines in motor vehicles. Recently, however, lead-acid batteries have also been used as energy stores for storing regeneratively produced energies. For example, the energy generated by a solar system is stored temporarily in lead-acid batteries, from which it can be taken if needed at a later date. The problem, however, is that when operating lead-acid batteries at a voltage of about 2.23 volts oxyhydrogen may occur. Since oxyhydrogen represents a detonable mixture of gaseous hydrogen and oxygen, the operation of lead-acid batteries indoors is not completely safe. Although an appropriately equipped ventilation in such rooms would largely avoid this danger. The installation of a ventilation system is not always possible or very expensive.
Zu diesem Zweck sind Knallgasoxidierer auf dem Markt erhältlich, die im Inneren einen Palladiumstab enthalten, an dem das Knallgas zu Wasser bzw. Wasserdampf oxidiert. Diese Knallgasoxidierer werden direkt in die Füllöffnung, durch die normalerweise der Bleiakkumulator mit Schwefelsäure als Elektrolyt befüllt wird, eingesetzt. Beim Betrieb des Bleiakkumulators entweicht das Knallgas aus dem Inneren direkt in den Knallgasoxidierer, wo das Knallgas in Wasserdampf und durch Kondensation an der Innenseite der Wände des Knallgasoxidierers in Wasser umgewandelt wird. Das kondensierte Wasser gelangt so wieder in das Innere des Bleiakkumulators. Für jeden Bleiakkumulator muss allerdings ein derartiger Knallgasoxidierer vorgesehen werden, was bei Energiespeichersystemen, die eine Vielzahl von Bleiakkumulatoren umfassen, sehr kostspielig ist.For this purpose, oxyhydrogen gas generators are available on the market, which contain inside a palladium rod, at which the oxyhydrogen gas oxidizes to water or water vapor. These oxyhydrogen oxidizers are used directly in the filling opening, through which normally the lead-acid battery is filled with sulfuric acid as the electrolyte. During operation of the lead-acid battery, the oxyhydrogen gas escapes from the interior directly into the oxyhydrogen gas oxidizer, where the oxyhydrogen gas is converted into water by condensation and condensation on the inside of the oxyhydrogen gas generator walls. The condensed water returns to the interior of the lead-acid battery. However, such a blast gas oxidizer must be provided for each lead-acid battery, which is very costly in energy storage systems that include a variety of lead-acid batteries.
Eine Aufgabe der vorliegenden Erfindung besteht darin, ein kostengünstiges Gehäuse zur Aufnahme einer Vielzahl von Bleiakkumulatoren vorzusehen, durch das die von dem entstehenden Knallgas ausgehende Gefahr minimiert oder weitestgehend vermieden wird.An object of the present invention is to provide a low-cost housing for accommodating a plurality of lead-acid batteries, by which the danger emanating from the resulting blast gas is minimized or largely avoided.
