Description

Vorrichtung zur Messung des Betriebszustandes, insbesondere des jeweiligen Lade- und Entladezustandes, einer elektrischen Sammlerbatterie Die vorliegende Erfindung bezieht sich auf eine Vorrichtung zur Feststellung des Betriebszustandes, insbesondere des jeweiligen Lade- undEntladezustandes, einer elektrischen Sammlerbatterie unter Verwendung eines Spannungsmessers mit einer Kompensierungsschaltung .gemäß dem Hauptpatent 621 36;. Bei dem Meßinstrument gemäß dem erwähnten Hauptpatent wird ein Shunt verwendet, an dessen Enden ein Teil des Lade- bzw. Entladestromes der Batterie über das Meßinstrument und einen Widerstand abgezweigt wird. Der Widerstandswert dieses Shuntes ist zwar verhältnismäßig sehr klein; trotzdem ergibt sich, insbesondere bei Starterbatterien, welche mit sehr hohen Entladeströmen belastet werden, der Nachteil, daß die Startfähigkeit durch den Spannungsabfall an dem erwähnten Shunt erheblich beeinträchtigt wird.Device for measuring the operating state, in particular the respective State of charge and discharge of an electrical storage battery The present invention relates to a device for determining the operating state, in particular the respective charge and discharge status, an electrical collector battery Use of a voltmeter with a compensation circuit .according to the main patent 621 36 ;. In the measuring instrument according to the main patent mentioned, a shunt is used, at its ends a part of the charging or discharging current of the battery via the measuring instrument and a resistor is branched off. The resistance value of this shunt is indeed relatively very small; nevertheless, especially with starter batteries, which are loaded with very high discharge currents, the disadvantage that the starting ability is significantly impaired by the voltage drop at the shunt mentioned.

Dieser Nachteil wird bei .der Vorrichtung zur Feststellung des Betriebszustandes unter Verwendung des erwähnten Spannungsmessers dadurch vermieden, daß an Stelle eines besonderen Shuntes zum Abzweigen eines Teiles des Lade- und Entladestromes der Batterie ein in der Stromverbindung zwischen Batterie und Verbraucher liegendes Kabel als Shunt benutzt wird. Erfindungsgemäß sind die an dem als Shun@t verwendeten Kabel angeschlossenen Abzweigungen zum Meßinstrument bzw. zum Widerstand der Stromverzweigung mit dem Kabel mechanisch und elektrisch fest verbunden. Zweckmäßig besteht das als Shunt verwendete Kabel aus Widerstandsmaterial. Man kann aber auch dem als Shunt verwendeten Kabel einen entsprechend kleineren Querschnitt geben als derjenige der übrigen Stromverbindung zwischen Batterie. und Stromverbraucher.This disadvantage arises in the case of the device for determining the operating state avoided using the aforementioned voltmeter in place a special shunt for branching off part of the charging and discharging current the battery is in the power connection between battery and consumer Cable is used as a shunt. According to the invention are those used on the as Shun @ t Cable connected branches to the measuring instrument or to the resistance of the current branch mechanically and electrically firmly connected to the cable. Appropriately, this exists as a Shunt used cables made of resistance material. But you can also use it as a shunt The cables used have a correspondingly smaller cross-section than that of the remaining power connection between battery. and electricity consumers.

Die Abbildung zeigt ein Ausführungsbeispiel der Vorrichtung nach der Erfindung. Wie ersichtlich, führen von den Polen der Starterbatterie b je eine Verbindungsleitung zu dem Anlaßmotor na. Die eine, mit w bezeichnete Verbindungsleitung, welche an dem positiven Pol der Batterie angeschlossen ist, dient als Shunt für das Meßinstrument s bzw> den Abzweigwiderstand v. Die Abzweigleitungen h und 12 sind mit den Enden des Kabels w fest verlötet. Der negative Pol der Starterbatterie b ist über den Vorwiderstandr mit dem negativen Pol des Instrumentes bzw. mit dem anderen Ende des Abzweigwiderstandes v verbunden.The figure shows an embodiment of the device according to the invention. As can be seen, one connection line leads from each of the poles of the starter battery b to the starter motor na. The one connection line marked w , which is connected to the positive pole of the battery, serves as a shunt for the measuring instrument s or> the branch resistor v. The branch lines h and 12 are firmly soldered to the ends of the cable w. The negative pole of the starter battery b is connected via the series resistor r to the negative pole of the instrument or to the other end of the branch resistor v.
