Description

Die Erfindung betrifft eine Überwachungseinrichtung für aufladbare Akkumulatoren, insbesondere solchen aus Lithiumverbindungen, während des Aufladevorganges, wobei die Akkumulatoren bzw. Akkumulatorzellen bzw. Gruppen von Akkumulatorzellen vorzugsweise in Reihe geschaltet sind und ein Verfahren zum Überwachen des Ladevorganges.The invention relates to a monitoring device for chargeable accumulators, in particular those made of lithium compounds, during the charging process, wherein the accumulators or accumulator cells or groups of accumulator cells are preferably connected in series and a method for monitoring the charging process.

Bei verschiedenen Arten von Akkumulatoren insbesondere aus Lithiumverbindungen besteht die Gefahr von Beschädigungen während des Ladens von in Serie geschalteten Zellen durch ungleiche Spannungsverteilung. Weiterhin kann es vorkommen, das durch Fehler in den Zellen eine unzulässige Erwärmung auftritt.In various types of accumulators, in particular lithium compounds, there is a risk of damage during charging of cells connected in series by unequal distribution of voltage. Furthermore, it may happen that an impermissible heating occurs due to errors in the cells.

Der Erfindung liegt die Aufgabe zugrunde, eine Überwachungseinrichtung der genannten Art sowie ein Verfahren zum Überwachen des Ladevorganges vorzuschlagen, damit keine Beschädigungen der Akkumulatoren eintreten.The invention has for its object to provide a monitoring device of the type mentioned and a method for monitoring the charging process, so that no damage to the batteries occur.

Diese Aufgabe wird mit einer erfindungsgemäßen Überwachungseinrichtung dadurch gelöst, dass jede Akkumulatorzelle bzw. Gruppe von Akkumulatorzellen mit einem sogenannten Balancer verbunden ist, der verschiedene Parameter, wie z.B. Temperatur des Akkumulators, anliegende Spannung, fließenden Strom zu messen und an eine zentrale Verarbeitungsstation weiterzugeben vermag.This object is achieved with a monitoring device according to the invention in that each accumulator cell or group of accumulator cells is connected to a so-called balancer, which has different parameters, such as e.g. Temperature of the accumulator, voltage applied to measure current flowing and can pass on to a central processing station.

Damit können alle Abweichungen von den Sollwerten zentral erfasst und auf einfache Weise beseitigt werden.This allows all deviations from the setpoint values to be recorded centrally and eliminated in a simple manner.

Äußerst vorteilhaft ist es auch, wenn der Balancer mit einer Regeleinrichtung zur Beeinflussung des Ladevorgangs ausgestattet ist.It is also extremely advantageous if the balancer is equipped with a control device for influencing the charging process.

Damit kann der Ladevorgang auf einfache Art und Weise so gesteuert werden, daß die Sollwerte eingehalten werden.Thus, the charging process can be controlled in a simple manner so that the setpoints are met.

Als sehr vorteilhaft hat es sich gemäß einer weiteren Ausgestaltung der Erfindung ergeben, wenn die Balancer mit Lichtsendern und Lichtempfängern ausgestattet sind, über welche die ermittelten Daten an andere Balancer bzw. die zentrale Verarbeitungsstation weitergegeben werden können.It has proved to be very advantageous according to a further embodiment of the invention if the balancers are equipped with light transmitters and light receivers, via which the determined data can be forwarded to other balancers or the central processing station.

Hiermit lassen sich die Daten sehr leicht potentialfrei übertragen.This allows the data to be transmitted very easily potential-free.

Dabei hat es sich als besonders vorteilhaft ergeben, wenn erfindungsgemäß der erste Balancer einen Kabelanschluß mit einem potentialtrennenden Interface aufweist, wodurch die Verbindung zur Verarbeitungsstation räumlich flexibel ausgestaltet werden kann.It has been found to be particularly advantageous if according to the invention the first balancer has a cable connection with a potential-separating interface, whereby the connection to the processing station can be made spatially flexible.

Eine weitere vorteilhafte Ausgestaltung der Erfindung liegt darin, dass auch der letzte Balancer mit einem Kabelanschluß zum Verbinden mit einer weiteren Gruppe von Akkumulatoren-Zellen versehen ist.A further advantageous embodiment of the invention is that even the last balancer is provided with a cable connection for connection to a further group of accumulator cells.

Damit können räumlich unabhängig von einander mehrere Gruppen von Akkumulatoren-Zellen überwacht werden.This allows spatially independent monitoring of several groups of accumulator cells.

Gemäß einem vorteilhaften erfindungsgemäßen Verfahren zum Überwachen des Ladevorganges von aufladbaren Akkumulatoren aus mehreren Zellen oder Zellengruppen, insbesondere solchen aus Lithiumverbindungen, die zum Aufladen in Reihe an eine Spannungsquelle angeschlossen sind, ist vorgesehen, dass in einem ersten Schritt die Zellen bzw. Zellengruppen von der Verarbeitungsstation über in sogenannten Balancern angeordneten Lichtsender bzw. Lichtempfänger durchnummeriert werden.According to an advantageous inventive method for monitoring the charging process of rechargeable batteries of several cells or groups of cells, in particular those of lithium compounds that are connected for charging in series to a voltage source, it is provided that in a first step, the cells or groups of cells from the processing station be numbered via arranged in so-called balancers light emitter or light receiver.

Infolge dieser Durchnummerierung können die anschließend übermittelten Meßdaten jeder einzelnen Zelle bzw. Zellengruppe zugeordnet werden, so dass bei unzulässigen Abweichungen entweder automatisch oder manuell eingegriffen werden kann.As a result of this numbering, the subsequently transmitted measured data can be assigned to each individual cell or cell group, so that it is possible to intervene automatically or manually in the event of impermissible deviations.

Eine weitere vorteilhafte Ausgestaltung der Erfindung liegt darin, dass die Messdaten und/oder die Regelungsdaten jedes einzelnen Balancers über die Lichtsender bzw. Lichtempfänger an den benachbarten Balancer weitergegeben werden.A further advantageous embodiment of the invention is that the measurement data and / or the control data of each individual balancer are forwarded via the light emitter or light receiver to the adjacent balancer.

Hierdurch wird erreicht, dass keine unmittelbare Verbindung der einzelnen Balancer zur Verarbeitungsstation notwendig ist, was sehr aufwendig wäre.This ensures that no direct connection of the individual balancer to the processing station is necessary, which would be very expensive.

Ebenfalls sehr vorteilhaft hat es sich erfindungsgemäß erwiesen, wenn die Meßdaten jedes einzelnen Balancers an die Verarbeitungsstation weitergegeben werden.Likewise, it has proved to be very advantageous according to the invention if the measurement data of each individual balancer are forwarded to the processing station.

Damit können die Meßdaten zentral aufbereitet werden um den Ladevorgang zu überwachen und zu steuern.Thus, the measured data can be processed centrally to monitor the charging process and control.

Äußerst vorteilhaft ist es erfindungsgemäß auch, wenn jeder Balancer den Ladevorgang einer Akkumulatorzelle bzw. Zellengruppe steuert, beispielsweise durch Anpassung der Ladespannung und/oder des Ladestroms.It is also extremely advantageous according to the invention if each balancer controls the charging process of an accumulator cell or cell group, for example by adapting the charging voltage and / or the charging current.

Dadurch wird eine optimale und schonende Ladung jeder einzelnen Einheit sichergestellt.This ensures optimal and gentle charging of each individual unit.

Dabei ist es sehr vorteilhaft, wenn der Ladevorgang jedes Balancers durch die Verarbeitungsstation gesteuert wird.It is very advantageous if the loading process of each balancer is controlled by the processing station.

Hierdurch ist der Ladevorgang zentral steuerbar und die einzelnen Einheiten können miteinander koordiniert werden.As a result, the charging process is centrally controlled and the individual units can be coordinated with each other.

Gemäß einer weiteren Ausgestaltung der Erfindung ist es auch sehr vorteilhaft, wenn der Ladezustand der Akkumulatorzelle bzw. Zellengruppe, Temperatur und/oder andere Meßwerte erfasst werden und in die Regelung des Ladevorganges einfliesst.According to a further embodiment of the invention, it is also very advantageous if the state of charge of the battery cell or cell group, temperature and / or other measured values are detected and fed into the regulation of the charging process.

Dadurch werden Überladungen ebenso vermieden wie Unterladungen. Defekte können frühzeitig erkannt werden.This will avoid overloads as well as underloads. Defects can be detected early.

In der Zeichnung ist die Erfindung anhand eines Ausführungsbeispiels veranschaulicht. Dabei zeigen:In the drawing, the invention is illustrated by means of an embodiment. Showing:

1 eine Reihenschaltung von mehreren Akkumulatoren, wobei auf jedem dieser Akkumulatoren ein Balancer befestigt ist und 1 a series connection of a plurality of accumulators, wherein a balancer is mounted on each of these accumulators and

2 einen vergrößert dargestellten Balancer, der auf einem Akkumulator befestigt ist. 2 an enlarged illustrated balancer which is mounted on an accumulator.

Mit 1 bis 10 sind in 1 zehn Akkumulatoren bezeichnet, die in Reihe geschaltet sind und von einer Photovoltaik-Anlage 11 mit Spannung versorgt werden. Auf jedem dieser Akkumulatoren ist ein Balancer 12 befestigt, der den jeweiligen Zustand des Akkumulators erfasst. Die hierbei erfassten Daten, wie anliegende Spannung, Temperatur des Akkumulators, fliessender Ladestrom und dergleichen wird an eine Verarbeitungsstation 13 weitergeleitet.With 1 to 10 are in 1 refers to ten accumulators connected in series and from a photovoltaic system 11 be supplied with voltage. On each of these accumulators is a balancer 12 attached, which detects the respective state of the accumulator. The data recorded here, such as voltage applied, temperature of the accumulator, flowing charging current and the like, is sent to a processing station 13 forwarded.

Wie besonders aus 2 ersichtlich, sind die Balancer 12 mit einem Lichtsender 14 und einem Lichtempfänger 15 ausgestattet. Darüber hinaus sind sie mit Sensoren zum Erfassen der Wärme des Akkumulators sowie mit einer Spannungs-Meßeinrichtung bestückt. Zusätzlich können noch weitere Meßeinrichtungen vorgesehen sein. Eine Einrichtung zum Erfassen einer Ordnungszahl für den einzelnen Balancer ist ebenfalls vorgesehen, so dass jedem Balancer von der Verarbeitungsstation eine Hausnummer zugeordnet werden kann.How special 2 Obviously, the balancers are 12 with a light transmitter 14 and a light receiver 15 fitted. In addition, they are equipped with sensors for detecting the heat of the accumulator and with a voltage measuring device. In addition, further measuring devices can be provided. A device for detecting an ordinal number for the individual balancer is also provided, so that each balancer can be assigned a house number by the processing station.

Im Störungsfall kann dann die Verarbeitungsstation den ermittelten Fehler genau dem auffälligen Balancer und damit dem gestörten Akkumulator zuordnen.In the event of a fault, the processing station can then assign the detected error precisely to the conspicuous balancer and thus to the faulty accumulator.

Die erfassten Daten werden über die Lichtsender und die Lichtempfänger von einem Balancer zum benachbarten übertragen. Der letzte Balancer ist dann mit einem potentialtrennenden Interface bzw. einem Optokoppler 16 ausgestattet, das die Daten über Leitungen zur Verarbeitungsstation weiterleitet.The acquired data is transmitted via the light emitter and the light receiver from one balancer to the next. The last balancer is then with a potential-separating interface or an optocoupler 16 equipped, which forwards the data via lines to the processing station.

Umgekehrt werden Befehle der Verarbeitungsstation an den jeweiligen Balancer auf dem umgekehrten Weg zurückgeleitet, wobei dort beispielsweise bei zu hoher anliegender Spannung ein Widerstand vorgeschaltet werden kann. Hierbei sind auch Pulsweitenmodulationen oder andere Regelungsmöglichkeiten zur Spannungs- und Stromregelung denkbar.Conversely, commands of the processing station are returned to the respective balancer on the opposite way, where there may be a resistor upstream, for example, at too high a voltage applied. Here also pulse width modulations or other control options for voltage and current control are conceivable.
