Description
Für die Batterieladung wird der Batteriebehälterdeckel abgenommen, damit die Ladegase ungehindert abziehen können. Nach beendeter Ladung ist noch ein Nachgasen der Zellen bemerkbar. Wird der Deckel nach der Ladung zu früh aufgelegt, so kann eine Ansammlung von Gasen im Behälter auftreten. Um dieses zu vermeiden, hat man im Behälterdeckel senkrechte Bohrungen angebracht, die aber den Nachteil haben, daß durch diese Regenwasser oder andere Flüssigkeiten sowie Staub usw. in die Zellen gelangen können. Über die Deckelöffnungen hat man zwar Ventilationsaufsätze vorgesehen, die das Eindringen von Flüssigkeiten und Staub in die Batterien einschränken. Bei Batterien in Fahrzeugen, z.B. Elektrokarren, ist jedoch die zur Verfügung stehende Raumhöhe für die Batterieunterbringung oftmals beschränkt, so daß für Ventilationsaufsätze auf dem Behälterdeckel kein Platz verbleibt.To charge the battery, the battery container lid is removed to allow the charge gases can pull off unhindered. After charging has ended, post-gassing of the cells is still noticeable. If the lid is after the If the load is applied too early, an accumulation of gases in the container can occur. In order to avoid this, vertical holes have been made in the container lid but have the disadvantage that rainwater or other liquids as well as dust etc. can get into the cells. There are ventilation attachments over the lid openings which limit the ingress of liquids and dust into the batteries. In the case of batteries in vehicles, e.g. electric carts, however, the available room height is often limited for battery accommodation, so that there is no space left on the container lid for ventilation attachments.
Nach der Erfindung werden diese Nachteile dadurch behoben, daß man die Austrittsöffnungen der Entlüftungskanäle in die Seitenflächen des Deckels legt.According to the invention, these disadvantages are eliminated by the fact that the outlet openings the ventilation channels in the side surfaces of the lid.
Die Abb. ι zeigt im Schnitt eine Ausführungsform der Erfindung. Der Behälter b, auf den der Deckel d aufgesetzt ist, ist durch Teilschnitt angedeutet. Die Austrittsöffnungen α der durch den Deckel d hindurchgeführten Kanäle k liegen, wie ersichtlich, in den Seitenflächen des Deckels.Fig. Ι shows in section an embodiment of the invention. The container b, on which the cover d is placed, is indicated by a partial section. The outlet openings α of the channels k passed through the cover d are, as can be seen, in the side surfaces of the cover.
Ein weiterer Vorteil wird nach der Erfindung dadurch erzielt, daß, wie die Abb. 2 beispielsweise zeigt, der Deckel d in seinem mittleren Teil durch Querschnittsverminderung erzeugte Aussparungen s besitzt, von welchen die Entlüftungskanäle k ausgehen. Ferner kann man nach der Erfindung den Deckel d, wie Abb. 3 beispielsweise zeigt, an dem Rande seiner Innenfläche mit einer rahmenartigen Verstärkung r versehen, durch welche die Entlüftungskanäle k hindurch in das Innere des Behälters geführt sind.A further advantage is achieved according to the invention in that, as FIG. 2 shows, for example, the cover d has recesses s produced in its central part by reducing the cross section, from which the venting channels k extend. Furthermore, according to the invention, the lid d, as shown in FIG. 3, for example, can be provided on the edge of its inner surface with a frame-like reinforcement r through which the ventilation channels k are guided into the interior of the container.
Die Saugwirkung der Entlüftungskanäle k kann nach der Erfindung, wie Abb. 1 beispielsweise zeigt, dadurch verbessert werden, daß die in verschiedenen Seitenflächen liegenden Austrittsöffnungen a! der Kanäle in verschiedener Höhenlage gegenüber den Austrittsöffnungen a" angeordnet sind. Die Saugwirkung der Entlüftungskanäle kann nach der Erfindung auch dadurch gesteigert werden, daß, wie Abb. 4 beispielsweise zeigt, über die Austrittsöffnungen a der Kanäle k Hauben oder Rohre e' und e", z.B. aus Blech, gesetzt werden, deren nach außenThe suction effect of the ventilation channels k can be improved according to the invention, as shown in FIG. 1, for example, in that the outlet openings a! of the channels are arranged at different heights with respect to the outlet openings a " . The suction effect of the ventilation channels can also be increased according to the invention in that, as Fig. 4 shows, for example, hoods or pipes e ' and e" via the outlet openings a of the channels k , for example made of sheet metal, are set, their to the outside

führende Öffnungen o' und o" in verschiedener Höhenlage liegen können. Um das Eindringen von Staub in den Behälter zu verhindern, können die Entlüftungskanäle, wie Abb.5 beispielsweise in Aufsicht zeigt, labyrinthartig verlaufen. Endlich kann die Sohle der Entlüftungskanäle k, wie Abb. 6 beispielsweise zeigt, mit Schwellen versehen sein, um das Eindringen von Flüssigkeit in das Innere des Behälters aufzuhalten.leading apertures o 'and o "may be in different height position. In order to prevent the penetration of dust into the container, the venting channels as Fig.5 shows, for example, in plan view, extend labyrinthine. Finally k can the sole of the venting channels, as shown in Fig Figure 6 shows, for example, be provided with thresholds to prevent the ingress of liquid into the interior of the container.
Es sind Entlüftungsventile bekannt, bei welchen die Austrittsöffnungen der Gase in den Seifenflächen der Ventile liegen, doch werden diese Ventile auf demDeckel des Sammlergefäßes aufgebracht, so daß sie die Oberfläche des Deckels überragen, und die Austrittsöffnung für die Gase befindet sich im obersten Teil des Ventils, also weit oberhalb der Deckelfläche. Im Gegensatz dazu bezieht sich die Erfindung auf Deckel, welche keinerlei vorspringende Teile besitzen und deren Entlüftungskanäle im Innern des Deckels liegen. There are vent valves known at which the outlet openings of the gases are in the soapy surfaces of the valves, but these valves are placed on the lid of the collector vessel so that they cover the surface of the lid, and the outlet opening for the gases is in the uppermost Part of the valve, well above the cover surface. In contrast, the Invention on covers which have no protruding parts and whose ventilation channels are located inside the cover.
