Description
Schaltungsanordnung zur Ladung von Akkumulatoren Die Erfindung betrifft eine Schaltungsanordnung zur Ladung von Akkumulatoren, insbesondere von Quecksilberoxid-Zinkakkumulatoren mit spannungsbegrenzendem Bauelement und optischer Be- -triebszustandsanzeige. Circuit arrangement for charging accumulators The invention relates to a circuit arrangement for charging accumulators, in particular mercury oxide-zinc accumulators with voltage-limiting component and optical operating status display.
Ladegeräte für Akkumulatoren, beispielsweise für Bleiakkumulatoren, enthalten im allgemeinen Bauelemente, die die Ladung bei Erreichen einer bestimmten Spannung am Akkumulator, beispielsweise bei Erreichen der Gasungsspannung, abschalten. Neben Relais werden dazu in vielen Fällen Zenerdioden verwendet. Weiter besitzen solche Geräte Kontrolleuchten zur optischen Betriebszustandsanzeige.Chargers for accumulators, e.g. for lead accumulators, generally contain components that reduce the charge when it reaches a certain level Switch off the voltage on the accumulator, for example when the gassing voltage is reached. In addition to relays, Zener diodes are used for this in many cases. Continue to own such devices control lights for visual operating status display.
Aufgabe der vorliegenden Erfindung ist es, die bisher üblichen Kontrolleuchten, die eine sehr viel geringere Lebensdauer besitzen als die übrigen im Ladegerät verwendeten Halbleiterbauelemente, zu ersetzen.The object of the present invention is to provide the control lights customary up to now, which have a much shorter lifespan than the others used in the charger Semiconductor components to replace.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß im Ladestromkreis des Akkumulators eine Lumineszenzdiode zur Anzeige des Betriebszustandes angeordnet ist.According to the invention, this object is achieved in that in the charging circuit of the accumulator, a luminescent diode is arranged to display the operating status is.
Besonders vorteilhaft ist es, zur Spannungsbegrenzung bei der Ladung die Schleusenspannung dieser Lumineszenzdiode auszunutv zen, sodaß die bisher übliche'und notwendige. Zenerdiode ala pannungsbegrenzendes Bauelement entfallen kann.It is particularly advantageous to limit the voltage when charging the lock voltage of this luminescent diode to be used, so that the hitherto usual'und necessary. Zener diode ala voltage-limiting component can be omitted.
Im folgendem ist anhand der Figuren 1 bis 3, die verschiedene Ausführungsformen einer erfindungsgemäßen Schaltungsanordnung zeigen, der Gegenstand der Erfindung näher erläutert.In the following, with reference to FIGS. 1 to 3, the various embodiments show a circuit arrangement according to the invention, the subject of the invention explained in more detail.
Gemäß Figur 1 wird der Akkumulator 1, beispielsweise ein &uecksilberoxid-Zinkakkumulator, über den Gleichrichter 2 mit einer Gleichspannung versorgt. Parallel zum Akkumulator 1 liegt eine Lumineszenzdiode 3, deren Schleusenspannung zur Spannungsbegrenzung bei der Ladung ausgenutzt wird. Zur Einstellung der Ladeendspannung dient der einstellbare Widerstand 4. Die Diode 5 verhindert einen Rückstrom vom Akkumulator durch die Luminenszenzdiode 3, die bei Beendigung des Ladevorganges aufleuchtet. Eine solche Anordnung arbeitet sehr zuverlässig, da die Luminenszenzdioden einen ausgeprägten Knick bei Erreichen der Schleusenspannung besitzen.According to Figure 1, the accumulator 1, for example a & uecksilberoxid-zinc accumulator, Supplied with a DC voltage via the rectifier 2. Parallel to the accumulator 1 there is a luminescent diode 3, whose lock voltage is used to limit the voltage is used during the charge. The adjustable one is used to set the end-of-charge voltage Resistor 4. The diode 5 prevents a reverse current from the accumulator through the luminescent diode 3, which lights up when the charging process is completed. Such an arrangement works very reliable because the luminescent diodes have a pronounced kink when they are reached the lock voltage.
Figur 2 zeigt eine weitere Schaltungsanordnung gemäß der Erfindung, bei der in an sich bekannter Weise parallel zum Akkumulator 1 eine Zenerdiode 6 geschaltet ist, Die Durchbruchspannung der Zenerdiode ist dabei so gewählt, daß sie der Ladeendspannung des Akkumulators 1 entspricht. Die Lumineszenzdiode 3 liegt hier in Reihe mit dem Akkumulator 1, leuchtet bei Ladung auf und verhindert einen Rückstrom vom Akkumulator über die Zenerdiode 6, beziehungsweise Gleichrichter 2. Der Widerstand 4 dient auch hier zur Einstellung der Ladendspannung.Figure 2 shows a further circuit arrangement according to the invention, in which, in a manner known per se, a zener diode 6 parallel to the accumulator 1 is switched, the breakdown voltage of the Zener diode is chosen so that it corresponds to the end-of-charge voltage of the accumulator 1. The light emitting diode 3 is located here in series with the accumulator 1, lights up when charging and prevents one Return current from the accumulator via the Zener diode 6 or rectifier 2. The resistor 4 is also used here to set the end-of-charge voltage.
Gemäß Figur 3 liegt parallel zum Akkumulator 1, der über den Gleichrichter 2 gespeist wird, eine Zenerdiode 6 mit einstellbarem Widerstand 7 zum Einstellen der Ladeendspannung. Beim Laden fließt der Ladestrom über die Lumineszenzdiode 3, den Akkumulator 1 und den geöffneten Transistor 8, die Lumineszenzdiode 3 leuchtet dabei auf. Bei Erreichen der Ladeschlußspannung bricht die Zenerdiode 6 durch, steuert den Transistor 9 auf und Transistor 8 sperrt.According to Figure 3 is parallel to the accumulator 1, the rectifier 2 is fed, a Zener diode 6 with an adjustable resistor 7 for setting the end-of-charge voltage. When charging, the charging current flows through the luminescent diode 3, the accumulator 1 and the open transistor 8, the luminescent diode 3 lights up thereby on. When the end-of-charge voltage is reached, the Zener diode 6 breaks down and controls the transistor 9 on and transistor 8 blocks.
