Description

Vorrichtung zum Feststellen des Ladezustandes von Akkumulatoren Die Erfindung betrifft eine Vorrichtung zum Festetellen des Ladezustandes von Akkumulatoren, mit einem Analogspeicher. Device for determining the state of charge of accumulators Die The invention relates to a device for determining the state of charge of accumulators, with an analog memory.

Die bisher bekannten Vorrichtungen zur Betätigung von Akkumulator-LadegerSten beruhen meistens auS einer Betätigung von Hand oder auf einem empirisch festgesetzten Zeitprogramm. .The previously known devices for actuating accumulator chargers are mostly based on an actuation by hand or on an empirically established one 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 Laderätes führt.However, these devices do not allow the actual state of charge to be determined of the accumulator to determine exactly what will reduce the life of the accumulator and leads to uneconomical operation of the charger.

Es ist dauer Aufgabe der Erfindung, diese Naahteil-e zu beseitigen, indem automatisch der Ladezustand auf eine ähnliche Art und Weise festgestellt wird, wie er im Labor gemessen wird.It is always the task of the invention to eliminate these near parts, by automatically determining the state of charge in a similar way, how it is measured in the laboratory.

Die Aufgabe wird dadurch gelöst, daß der Akkumulator mit dem Eingang des Analogspel¢hers 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 auStritt, um das Vergleichen durch den Komparator bzv. das Speichern durch den Analogspeicher eines neuen Meßwerts der Akkumulatorspannung auszulösen, und daß durch den Ausgang des Komparators ein Ladegerät steuerbar ist.The object is achieved in that the accumulator with the input of the analog player is connected, its output to an entrance of a comparator is connected, to whose second input the accumulator is connected is, with one further input each of the analog memory and the comparator the outputs of a measuring timer are connected, each of two consecutive Emits impulses, one of which emerges at one output and the other at the other, to compare by the comparator or. the storage by the analog memory trigger a new measured value of the battery voltage, and that through the output of the comparator a charger can be controlled.

Das Ferstellen 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 sec) wird dieser MeBwert mit dem HeBwert der 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 Ladege° rate. Wenn dieser Befehl nicht abgegeben wird, wird in den Analogspeicher ein neuer Meßwert der Akkumulatorspannung eingespeist, und der Funktionslauf wiederholt sich.The completion 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 sec), this measured value is combined with the HeBwert the then existing battery voltage compared by the comparator. Is the Voltage increase 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. If this command is not issued, a new measured value is stored in the analog memory the battery voltage is fed in, and the functional run is repeated.

Durch die erfindungsgemaße Vorrichtung zur Feststellung 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 werden die Lebensdauer des zugehörigen Akkumulators und die Wirtschaftlichkeit des Betriebes des Ladegerätes wesentlich erhöht.By means of the device according to the invention for determining the state of charge of the accumulator are the errors caused by the empirical estimation of the charging time arise, eliminated, in particular the influence of temperature, the charging current the charging of the battery and the battery age. This will increase the lifespan of the associated accumulator and the economic efficiency of the operation of the charger significantly increased.

Die Erfindung wird anhand der sinsi$e ur der Zeichnung näher erläutert, in der ein Ausführungsbeispiel der erfindungsgemäßen Vorrichtung abgebildet ist.The invention is explained in more detail based on the sinsi $ e ur of the drawing, in which an embodiment of the device according to the invention is shown.

Es sind zu sehen: ein Analogspeicher P, ein Komparator KJ ein Meßzeitgéber H, ein (geladener) Akkumulator B, ein Ausgangsanschluß k des Komparators K, eine Akkumulatorklemme b und Steuersignalausgänge hl J h2 des Meßzeitgebers H.The following can be seen: an analog memory P, a comparator KJ and a measuring timer H, a (charged) accumulator B, an output terminal k of the comparator K, a Accumulator terminal b and control signal outputs hl J h2 of the measuring timer H.

Der Meßzeitgeber H sendet nach Einstellen eines Zeitintervalls jeweils zwei aufeinanaerrolgende Impulse. Ein Impuls am Steuersignalausgang hl 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 h2 gibt den Befehl zum Speichern eines neuen Meßwerts der Akkumulatorspannung im Analogspeicher.The measuring timer H sends each time after setting a time interval two consecutive impulses. A pulse at the control signal output hl is the Command for comparison by the comparator K of the battery voltage and the one in the Analog memory P stored measured value of the battery voltage. A subsequent one The pulse at the control signal output h2 gives the command to save a new measured value the battery voltage in the analog memory.

Der über den Eingang p 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 steigen aufhört.The fed in via the input p of the comparator K from the analog memory P. The measured value is in the comparator K with the measured value fed in via the input b compared to the actual battery voltage. The comparator K sends in at the output k Signal off that commands the charger to be switched off when the voltage of the charged accumulator stops rising.
