Abstract

The charge condition monitor and control, for a battery charger, has a measuring-time generator which is used to produce a first control pulse, which is passed to a comparator, and there is a second control pulse, which is passed to an analog store. The store holds the value of the battery terminal voltage when the latter is measured and passes it to the comparator on receipt of the second control pulse. The comparator compares the stored voltage with the actual voltage across the battery terminals and its output is used to regulate the charging process. The two control pulses are sequential not coincident.

Description

Die Erfindung betrifft eine Vorrichtung zum Feststellen des Ladezustandes von Akkumulatoren und zum Steuern eines Ladegerätes mit einem Analogspeicher.The invention relates to a device for determining the state of charge of batteries and for Controlling a charger with an analog memory.

Die bisher bekannten Vorrichtungen zur Betätigung von Akkumulator-Ladegeräten beruhen meistens auf einer Betätigung von Hand oder auf einem empirisch festgesetzten Zeitprogramm.The previously known devices for operating battery chargers are mostly based on actuation by hand or on an empirically established time program.

Diese Vorrichtungen erlauben jedoch nicht, den tatsächlichen Ladezustand des Akkumulators genau festzustellen, was zur Herabsetzung der Lebensdauer des Akkumulators und zu einem unwirtschaftlichen Betrieb des Ladegerätes führt.However, these devices do not allow the actual state of charge of the accumulator to be determined precisely, resulting in a reduction in the service life of the accumulator and an uneconomical operation of the charger leads.

Es ist daher Aufgabe der Erfindung, diese Nachteile zu beseitigen, indem automatisch der Ladezustand auf eine ähnliche Art und Weise festgestellt wird, wie er im Labor gemessen wird.It is therefore the object of the invention to eliminate these disadvantages by automatically increasing the charge status is determined in a manner similar to how it is measured in the laboratory.

Die Aufgabe wird dadurch gelöst, daß der Akkumulator mit dem Eingang des Analogspeichers verbunden ist, dessen Ausgang an einen Eingang eines Komparators angeschlossen ist, an dessen zweiten Eingang der Akkumulator angeschlossen ist, wobei mit je einem weiteren Eingang des Analogspeichers und des Komparators die Ausgänge eines Meßzeitgebers verbunden sind, der jeweils zwei aufeinanderfolgende Impulse abgibt, von denen der eine am einen und der andere am anderen Ausgang auftritt, um das Vergleichen durch den Komparator bzw. das Speichern durch den Analogspeicher eines neuen Meßwerts der Akkumulatorspannung auszulösen, und daß durch den Ausgang des Komparators ein Ladegerät steuerbar ist.
Das Feststellen des Ladezustands wird also durch den Meßzeitgeber gesteuert. In den Analogspeicher wird ein Meßwert der Akkumulatorspannung eingespeist, und nach einem gewissen Zeitintervall (z. B. 0,1 see) wird dieser Meßwert mit dem Meßwert der
The object is achieved in that the accumulator is connected to the input of the analog memory, the output of which is connected to an input of a comparator, to the second input of which the accumulator is connected, the outputs of one each with a further input of the analog memory and the comparator Measuring timer are connected, which emits two consecutive pulses, one of which occurs at one output and the other at the other output, in order to trigger the comparison by the comparator or the storage by the analog memory of a new measured value of the battery voltage, and that through the output of the comparator a charger can be controlled.
The determination of the state of charge is thus controlled by the measuring timer. A measured value of the battery voltage is fed into the analog memory, and after a certain time interval (e.g. 0.1 seconds) this measured value becomes the measured value of the

ίο dann vorhandenen Akkumulatorspannung durch den Komparator verglichen. Ist die Spannungszunahme Null oder kleiner als der Wert, der dem Ladezustand des Akkumulators entspricht, dann sendet der Komparator einen Befehl zum Abschalten des Ladegerätes.ίο then existing battery voltage through the Comparator compared. If the voltage increase is zero or less than the value that corresponds to the state of charge of the accumulator corresponds, then the comparator sends a command to switch off the charger.

Wenn dieser Befehl nicht abgegeben wird, wird in den Analogspeicher ein neuer Meßwert der Akkumulatorspannung eingespeist, und der Funktionslauf wiederholt sich.If this command is not issued, a new measured value of the battery voltage is stored in the analog memory fed in, and the functional run is repeated.

» stellung des Ladezustandes des Akkumulators werden die Fehler, die durch die empirische Abschätzung der Ladezeit entstehen, eliminiert, insbesondere der Einfluß der Temperatur, der Ladestromstärke der Aufladung des Akkumulators und des Akkumulatoralters. Dadurch»Position of the charge level of the accumulator eliminates the errors that arise from the empirical estimation of the loading time, in particular the influence the temperature, the charging current of the charging of the accumulator and the accumulator age. Through this

»5 werden die Lebensdauer des zugehörigen Akkumulators und die Wirtschaftlichkeit des Betriebes des Ladegerätes wesentlich erhöht.»5 will be the service life of the associated accumulator and the efficiency of the operation of the charger is significantly increased.

Die Erfindung wird an Hand der Figur der Zeichnung näher erläutert, in der ein Ausführungsbeispiel der erfindungsgemäßen Vorrichtung abgebildet ist.The invention is explained in more detail with reference to the figure of the drawing, in which an embodiment the device according to the invention is shown.

Es sind zu sehen: ein Analogspeicher P, ein Komparator K, ein Meßzeitgeber H, ein (geladener) Akkumulator B, ein Ausgangsänschluß k des Komparators K, eine Akkumulatorklemme b und Steuersignalausgänge Al, Λ2 des Meßzeitgebers H. The following can be seen: an analog memory P, a comparator K, a measuring timer H, a (charged) accumulator B, an output connection k of the comparator K, an accumulator terminal b and control signal outputs A1, Λ2 of the measuring timer H.

Der Meßzeitgeber H sendet nach Einstellen eines Zeitintervalls jeweils zwei aufeinanderfolgende Impulse. Ein Impuls am Steuersignalausgang Λ1 gibt den Befehl zum Vergleich durch den Komparator K der Akkumulatorspannung und des in dem Analogspeicher P gespeicherten Meßwerts der Akkumulatorspannung. Ein darauf folgender Impuls am Steuersignalausgang Λ2 gibt den Befehl zum Speichern eines neuen Meßwerts der Akkumulatorspannang im Analogspeicher.The measuring timer H sends two consecutive pulses after a time interval has been set. A pulse on the control signal output Λ1 gives the instruction for comparison by the comparator K, the battery voltage and the value stored in the analog memory P measured value of the battery voltage. A subsequent pulse at the control signal output Λ2 gives the command to save a new measured value of the accumulator voltage in the analog memory.

Der über den Eingang ρ des Komparators K vom Analogspeicher P eingespeiste Meßwert wird in dem Komparator K mit dem über den Eingang b eingespeisten Meßwert der Ist-Akkumulatorspannung verglichen. Der Komparator K sendet am Ausgang k ein Signal aus, das das Ausschalten des Ladegerätes befiehlt, wenn die Spannung des geladenen Akkumulators zu sieigen aufhört.The measured value fed in from the analog memory P via the input ρ of the comparator K is compared in the comparator K with the measured value of the actual battery voltage fed in via the input b. The comparator K sends out a signal at the output k which commands the charger to be switched off when the voltage of the charged accumulator stops increasing.
