Description

Batterieladeeinrichtung Die Erfindung bezieht sich auf Batterieladeeinrichtungen, insbesondere für Kraftfahrzeuge mit Wechselstromgenerator, Gleichrichterbrücke und Batterie, bei welcher eine Anzeigelampe in Abhängigkeit von der Spannung an einem Gleichrichter gespeist wird.Battery charging device The invention relates to battery charging devices, especially for motor vehicles with alternator, rectifier bridge and Battery, in which an indicator lamp depending on the voltage on a Rectifier is fed.

Die Anzeigevorrichtung, wie sie gewöhnlich bei der elektrischen Ausrüstung beispielsweise von Motorrädern zur Anwendung kommt, um anzuzeigen, wann der Generator arbeitet, besteht aus einer Lampe, die an die Gleichstromseite eines Gleichrichters angeschlossen ist; der mit dem Stromgenerator verbunden ist.The display device, as is commonly found in electrical equipment for example, is used by motorcycles to indicate when the generator is running works consists of a lamp connected to the DC side of a rectifier connected; which is connected to the power generator.

Die Lampe wird hierbei von einem Hilfskontakt auf dem Ladeschalter eingeschaltet, wenn sich dieser in »Aus«-Stellung befindet. In einer anderen bekannten Anordnung ist dem Hauptkontakt des Ladeschalters eine Lampe parallel geschaltet.The lamp is operated by an auxiliary contact on the charging switch switched on when this is in the "off" position. In another well-known Arrangement, a lamp is connected in parallel to the main contact of the charging switch.

Derartige Anzeigevorrichtungen sind verhältnismäßig teuer, setzen infolge der Erschütterungen leicht aus oder sind nur in Verbindung mit Ladeschaltern geeignet.Such display devices are relatively expensive due to the vibrations or are only in connection with charging switches suitable.

Bei einer weiteren bekannten Anordnung ist zu dem Zweck, die Anfangserregung zu sichern und hierzu der Feldwicklung immer einen kleinen Strom zu liefern, selbst dann, wenn der Generator nicht in Betrieb ist, ein Widerstand parallel zu einem Gleichrichter geschaltet. Der Widerstand kann dabei eine Lampe sein, die dann als Anzeigevorrichtung dienen kann, um zu zeigen, wann die Vorrichtung in Betrieb ist.Another known arrangement is for the purpose of initial excitation and to always deliver a small current to the field winding, even then when the generator is not running, a resistor in parallel with one Rectifier switched. The resistor can be a lamp, which is then used as a Display device can serve to show when the device is in operation.

Zweck der Erfindung ist die Schaffung einer Batterieladeeinrichtung mit einer einfachen und billigen Anzeigevorrichtung, die auch für Anlagen ohne Ladeschalter geeignet ist.The purpose of the invention is to create a battery charger with a simple and cheap display device that can also be used for systems without a charging switch suitable is.

Dies wird erfindungsgemäß dadurch erreicht, daß die Anzeigelampe oder der Steuerteil eines Schaltgerätes für diese parallel zu einem der Brückengleichrichter geschaltet wird.This is achieved according to the invention in that the indicator lamp or the control part of a switching device for this parallel to one of the bridge rectifiers is switched.

Die Erfindung wird nunmehr an Hand der sie beispielsweise wiedergebenden Zeichnung näher erläutert, welche ein Schaltbild wiedergibt.The invention will now be illustrated by way of example Drawing explained in more detail, which shows a circuit diagram.

Ein Wechselstromgenerator 10, beispielsweise ein permanentmagnetischer Schwunggenerator, mit Ausgangsklemmen 11 und 12 ist an die Diagonale 13, 14 einer Gleichrichterbrücke 15 angeschlossen, die vier Zweige hat, von denen jeder einen Diodengleichrichter D, z. B. einen Trockengleichrichter, enthält. Eine Batterie 16 liegt an der anderen Diagonale, deren Endpunkte 17, 18 die Ausgangsklemmen bilden, von denen Gleichstrom abgenommen werden kann. Eine Anzeigelampe 19, beispielsweise eine kleine Glühfadenlampe, liegt parallel zu einer der vier Dioden D.An alternator 10, for example a permanent magnet swing generator, with output terminals 11 and 12 is connected to the diagonal 13, 14 of a rectifier bridge 15 which has four branches, each of which has a diode rectifier D, e.g. B. contains a dry rectifier. A battery 16 is located on the other diagonal, the end points 17, 18 of which form the output terminals from which direct current can be drawn. An indicator lamp 19, for example a small filament lamp, is parallel to one of the four diodes D.

Wenn der Generator arbeitet, so wird an der Lampe während jeder halben Periode, in der die Diode hohe Impedanz hat, eine Spannung erzeugt, die die Lampe aufleuchten läßt.When the generator is working, the lamp is turned on during every half Period when the diode has high impedance generates a voltage that the lamp lights up.

Bei einer abgeänderten Schaltung nach der Erfindung liegt ein auf Strom ansprechender Schalter an Stelle der Lampe parallel zu der Diode. Dieser Schalter kann einen Heizwiderstand, der parallel zur Diode liegt, sowie einen Bimetallkontakt aufweisen, der so eingerichtet ist, daß seine Kontakte offen sind, wenn das Heizelement infolge des Stromdurchgangs erwärmt wird. Die Kontakte sind in Reihe mit einer Anzeigelampe an die Batterie angeschlossen.In a modified circuit according to the invention there is a Current responsive switch in place of the lamp in parallel with the diode. This switch can have a heating resistor that is parallel to the diode, as well as a bimetal contact which is arranged so that its contacts are open when the heating element is heated as a result of the passage of current. The contacts are in series with an indicator lamp connected to the battery.

In diesem Falle wird das richtige Arbeiten des Generators dadurch angezeigt, daß die Lampe erlischt, jedoch kann, falls gewünscht, die Anordnung in umgekehrter Form verwendet werden, bei der die Kontakte sich schließen und die Lampe aufleuchten lassen, wenn Strom durch das Heizelement fließt.In this case the generator will work properly indicates that the lamp goes out, but if desired, the arrangement in reverse form can be used in which the contacts close and the lamp light up when current is flowing through the heating element.
