Description
Bei der Schnell-Ladung von Fahrzeugbatterien kommt es vor, daß eine z. B. 40zellige Batterie mit Mitterabgriff, deren Hälften verschieden entladen sind, geladen werden muß. Dabei besteht die Gefahr, daß der Regler für der Ladegleichrichter entsprechend einer Spannung von 2,q. V/Zelle, die Batteriespannung auf 96V, konstant hält, dabei jedoch eine Batteriehälfte unter 2,¢ V/Zelle und die andere darüber liegt und dabei Schaden leidet.When fast charging vehicle batteries, it happens that a z. B. 40-cell battery with center tap, the halves of which are differently discharged, must be loaded. There is a risk that the regulator for the charging rectifier corresponding to a voltage of 2, q. V / cell, the battery voltage at 96V, constant lasts, however, one half of the battery is below 2. ¢ V / cell and the other half above lies and suffers damage in the process.
Um diesen Nachteil zu verhindern, wird gemäß der Erfindung eine Anordnung für Ladeeinrichtungen angezapfter Batterien mit einer Brückenanordnung aus den Teilbatterien sowie- Widerständen vorgeschlagen, die dadurch gekennzeichnet ist, daß der im Falle unterschiedlicher Entladung der Teilbatterien auftretende Querstrom der Brücke als Meßgröße in den Meßkreis des Ladereglers eingeschleift ist.In order to obviate this disadvantage, an arrangement according to the invention for charging devices of tapped batteries with a bridge arrangement from the partial batteries as well as resistors proposed, which is characterized in that in the case different discharge of the partial batteries occurring cross current of the bridge than The measured variable is looped into the measuring circuit of the charge controller.
Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung. Die Batterie sei beispielsweise mittelangezapft. Parallel zu beiden Batteriehälften B1 und B2 liegt ein SpanungsteilerR1- R2. Die Batteriehälften Bi, B2 und die Teile R1, R2 des Spannungsteilers bilden die Brückenschaltung. In der Diagonale, also zwischen. den Mittelpunkten., liegt die Primärspule eines Gleichstromwandlers GW. Besteht zwischen Bi und B2 eine Spannungsdifferenz, so wird durch die Primärspule des Wandlers ein Ausgleichstrom fließen, welcher den Kern magnetisiert und dadurch den durch die Sekundärspule fließenden Wechselstrom steuert. Dieser Wechselstrom wird über einen Gleichrichter Gr gleichgerichtet und in das Fühlorgan des geregelten Ladegleichrichters L eingeschleust. Der Ausgleichstrom ist proportional der Spannungsdifferenz d U= UB, -U$2, wenn UB, und UB2 die Spannungen der Batterieteile B1 bzw. B2 sind. Seine Richtung spielt keine Rolle, weil die für die Steuereinrichtung des Reglers erforderliche Richtung durch den Nachfolgegleichrichter Gr festgelegt wird. Als Regler kann zweckmäßig ein aus mindestens einem magnetischen Verstärker aufgebauter Regelverstärker verwendet werden.The drawing shows an embodiment of the invention. The battery is, for example, drawn from the center. A voltage divider R1-R2 is located parallel to both battery halves B1 and B2. The battery halves Bi, B2 and the parts R1, R2 of the voltage divider form the bridge circuit. In the diagonal, i.e. between. the centers., the primary coil of a direct current converter GW lies. If there is a voltage difference between Bi and B2, a compensating current will flow through the primary coil of the converter, which magnetizes the core and thereby controls the alternating current flowing through the secondary coil. This alternating current is rectified via a rectifier Gr and channeled into the sensing element of the regulated charging rectifier L. The equalizing current is proportional to the voltage difference d U = UB, -U $ 2, if UB, and UB2 are the voltages of the battery parts B1 and B2, respectively. Its direction does not matter because the direction required for the control device of the regulator is determined by the subsequent rectifier Gr. A control amplifier made up of at least one magnetic amplifier can expediently be used as the controller.
Der magnetische Regler hält die Spannung zunächst auf UB,- U$2 = d U = konstant so lange, bis d U = o geworden ist, d. h. also, zwischen Bi und B2 kein Spannungsunterschied mehr besteht.The magnetic regulator initially keeps the voltage at UB, - U $ 2 = d U = constant until d U = 0 , ie there is no longer a voltage difference between Bi and B2.
