Description
Die vorliegende Erfindung betrifft ein Batterie-Management-System für eine aufladbare Batterie mit zumindest einer Batteriezelle, umfassend ein Steuergerät, ein mit einer externen Spannungsquelle verbundenes Ladegerät, einen Stromsensor, sowie zumindest einen Spannungssensor.The present invention relates to a battery management system for a rechargeable battery having at least one battery cell, comprising a control unit, a charger connected to an external voltage source, a current sensor, and at least one voltage sensor.
Weiterhin betrifft die Erfindung ein Verfahren zum Feststellen des Ladezustands einer aufladbaren Batterie.Furthermore, the invention relates to a method for determining the state of charge of a rechargeable battery.
Batterie-Management-Systeme sowie Verfahren zum Feststellen des Ladezustands einer aufladbaren Batterie der hier angesprochenen Art werden verwendet bei der Aufladung von Akkumulatoren, beispielsweise Blei-Säure-Akkumulatoren, aber auch bei der Aufladung von Akkumulatoren wie Nickel-Cadmium-Akkumulatoren, Nickel-Metallhydrid-Akkumulatoren, Lithium-Hydrid-Akkumulatoren oder dergleichen. Ein Akkumulator kann je nach Konstitution seiner Elektroden, seines Elektrolyten oder dergleichen beispielsweise ein Gel-, Vlies- oder auch Nassakkumulator sein, wie er insbesondere in Form eines Blei-Säure-Akkumulators im Bereich der Traktion sowie auch im stationären Einsatz, beispielsweise bei Krankenfahrstühlen, Reinigungsmaschinen, Flurförderfahrzeugen, Elektroautos, Notstromanlagen und dergleichen zum Einsatz kommt. Im Folgenden wird der Begriff Batterie als Synonym für sämtliche Arten wieder aufladbarer Batterien bzw. Akkumulatoren verwendet.Battery management systems and methods for determining the state of charge of a rechargeable battery of the type mentioned here are used in the charging of accumulators, such as lead-acid batteries, but also in the charging of batteries such as nickel-cadmium batteries, nickel-metal hydride Accumulators, lithium hydride accumulators or the like. Depending on the constitution of its electrodes, its electrolyte or the like, an accumulator can be, for example, a gel, nonwoven or else wet accumulator, in particular in the form of a lead-acid accumulator in the area of traction as well as in stationary use, for example in wheelchairs, Cleaning machines, industrial trucks, electric cars, emergency power systems and the like is used. In the following, the term battery is used as a synonym for all types of rechargeable batteries or accumulators.
Bislang sind im Zusammenhang mit dem Laden insbesondere von Bleibatterien nur Ladeverfahren bekannt, die sich auf das Erfassen der Gleichspannung und des Ladestroms stützen. Weiterbildungen sehen vor, schrittweise Ladestrom oder Ladespannung anzupassen, um einen maximalen Ladezustand der Batterie zu erreichen. In allen bekannten Verfahren wird die Batteriespannung als Kriterium für den Ladezustand herangezogen. Insbesondere bei Verschaltung mehrerer Batteriezellen in Serie kann bei diesen Verfahren nicht gewährleistet werden, dass alle Zellen in gleichem Maße geladen werden. Die Streuung der Innenwiderstände spielt hier ebenso hinein wie die Widerstände der Zellverbinder. Außerdem kann sich der Zusammenhang zwischen Ladezustand und Zellspannung mit zunehmender Alterung ändern, so dass der Ladezustand der Batterie über die Erfassung der Zellspannung nur indirekt und unzureichend genau erfasst wird.So far, in connection with charging, in particular lead-acid batteries, only charging methods are known which rely on the detection of the DC voltage and the charging current. Developments provide gradually adjust charging current or charging voltage to achieve a maximum state of charge of the battery. In all known methods, the battery voltage is used as a criterion for the state of charge. In particular, when connecting multiple battery cells in series can not be guaranteed in these methods that all cells are charged to the same extent. The scattering of the internal resistances plays just as much as the resistances of the cell connectors. In addition, the relationship between state of charge and cell voltage can change with increasing aging, so that the state of charge of the battery is detected only indirectly and insufficiently accurate via the detection of the cell voltage.

Die Offenlegungsschrift
Die erfindungsgemäß vorgeschlagene Vorrichtung sowie das erfindungsgemäße Verfahren ermöglichen durch eine erheblich verbesserte Erfassung des momentanen Ladezustands der Batterie eine an diesen Zustand angepasste Auswahl der besten Ladestrategie, so dass eine vollständigere und schonende Ladung erreichbar ist.The device proposed according to the invention and the method according to the invention make it possible to select the best charging strategy adapted to this condition by significantly improving the detection of the instantaneous state of charge of the battery, so that a more complete and gentle charging can be achieved.
Dies wird bezüglich des erfindungsgemäßen Batterie-Management-Systems dadurch erreicht, dass das Ladegerät ausgebildet ist, nach Maßgabe des Steuergeräts einen Ladestrom oder einen Entladestrom in die Batterie einzuprägen.This is achieved with respect to the battery management system according to the invention in that the charger is designed to impress a charge current or a discharge current in the battery in accordance with the control device.
Bezüglich des Verfahrens zum Feststellen des Ladezustands einer aufladbaren Batterie gelingt dies erfindungsgemäß dadurch, dass das Ladegerät einen Strom mit einem periodisch schwankenden Wert in die Batterie einprägt, und dass das Steuergerät mittels des Spannungssensors die Spannungsantwort der Batterie erfasst.With regard to the method for determining the state of charge of a rechargeable battery, this is achieved according to the invention by virtue of the charger impressing a current with a periodically fluctuating value into the battery, and by the voltage sensor detecting the voltage response of the battery.
Das erfindungsgemäße System sowie das Verfahren erlauben es, aufgrund des schwankenden Ladestroms bzw. auch der Kombination von Laden und Entladen, eine direktere Aussage über den Ladezustand zu treffen. Insbesondere bei hohen Ladezuständen, also bei vollständiger oder zumindest beinahe vollständiger Ladung der Batterie, und bei einer Batterie bestehend aus mehreren Batteriezellen, kann auf diese Weise eine genauere Aussage über den aktuellen Ladezustand bzw. auch über die Verteilung des Ladezustands innerhalb der Batterie getroffen werden als durch eine reine Spannungsmessung.The system according to the invention and the method make it possible to make a more direct statement about the state of charge due to the fluctuating charging current or else the combination of charging and discharging. In particular, at high states of charge, ie at full or at least almost complete charge of the battery, and in a battery consisting of several battery cells, can be made in this way a more accurate statement about the current state of charge or on the distribution of the state of charge within the battery by a pure voltage measurement.
Vorteilhafte Ausgestaltungen und Weiterbildungen des erfindungsgemäßen Batterie-Management-Systems sowie des erfindungsgemäßen Verfahrens ergeben sich aus den jeweiligen Unteransprüchen und werden anhand der Zeichnung erläutert.Advantageous embodiments and further developments of the battery management system according to the invention and the method according to the invention will become apparent from the respective dependent claims and will be explained with reference to the drawing.

Das mit dem Batterie-Management-System durchzuführende Verfahren zum Feststellen des Ladezustands einer aufladbaren Batterie
Nach dieser Messung wurde die Batteriezelle
Der Grund für die beobachtete Kurvenform liegt darin, dass zwar die Ladereaktion auch bei negativem Strom abläuft, dann aber als Entladereaktion, die Gasungsreaktion jedoch bei negativem Strom nicht ablaufen kann. Innerhalb einer Bleibatterie laufen neben der Hauptreaktion, also der Ladung oder Entladung, nämlich viele weitere chemische Reaktionen ab. Eine wesentliche davon ist die sogenannte Gasungsreaktion, die Zersetzung von Wasser in Sauerstoff und Wasserstoff. Diese Reaktion ist wie die Lade- bzw. Entladereaktion ebenfalls abhängig von der Zellspannung der Bleibatteriezelle. In der Realität finden immer beide Reaktionen gleichzeitig statt, so dass man messtechnisch immer eine Kurve ermitteln wird, die sich aus einem Gemisch der beiden Reaktionen ergibt. Mit zunehmendem Ladezustand während des Ladens ist weniger aktives Material in Form von Bleisulfat zum Umsetzen vorhanden, und die Ladereaktion kann nicht mehr in gleichem Maße stattfinden wie bei einem niedrigen Ladezustand. Als Folge davon ergibt sich für einen sehr hohen Ladezustand eine andere Reaktion als es bei einem niedrigen Ladezustand der Fall wäre. Ein in die Batterie eingeprägter Ladestrom wird also bei einem hohen Ladezustand zu einer anderen Spannung führen als bei einem tiefen Ladezustand.The reason for the observed waveform is that although the charging reaction proceeds even when the current is negative, it acts as an unloading reaction, but the gassing reaction can not proceed at a negative current. Within a lead-acid battery, besides the main reaction, ie the charge or discharge, many other chemical reactions take place. One of these is the so-called gassing reaction, the decomposition of water into oxygen and hydrogen. Like the charging or discharging reaction, this reaction is also dependent on the cell voltage of the lead-acid battery cell. In reality, both reactions always take place at the same time, so that one will always determine a curve by measurement, which results from a mixture of the two reactions. With increasing state of charge during charging, there is less active material in the form of lead sulphate to react, and the charging reaction can not take place to the same extent as with a low state of charge. As a result, a different reaction results for a very high state of charge than for a low state of charge Charge state would be the case. A charge current impressed into the battery will thus result in a different voltage at a high charge state than at a low charge state.
Ein weiterer Faktor, der zur Form der beobachteten Kurve beiträgt, ist die Tatsache, dass die Kurve der Gasungsreaktion wesentlich flacher verläuft als die der Ladereaktion, so dass ein kleiner Strom zu einer höheren Überspannung führt. Als Folge davon tritt bei einer vollgeladenen Batteriezelle als Reaktion auf den Ladestrom, also der positiven Halbwelle des Stroms in
Der Grad der Verzerrung eines sinusförmigen Signals lässt sich auf mehrere Arten quantitativ erfassen. Beispiele hierfür sind die Total Harmonic Distortion Analysis (THDA) oder der sog. Klirrfaktor, die aus der Leistungselektronik oder der technischen Akustik bzw. der Signalverarbeitung bekannt sind. Beiden Verfahren liegt die Erfassung der Oberschwingungen bzw. Harmonischen eines periodischen Signals zugrunde, wie es in dem hier vorliegenden Verfahren ebenfalls verwendet wird. Mit Hilfe z. B. also des Klirrfaktors und der hier beschriebenen Messmethode lässt sich auch bei einer großen Serienschaltung aus mehreren Batteriezellen deren einzelne Volladung mit geringem Rechenaufwand ermitteln. Dazu wird der Klirrfaktor der Spannungsantwort kontinuierlich für jede Zelle ermittelt. Sobald dieser einen noch festzulegenden Grenzwert überschritten hat, ist dies ein Zeichen für das Erreichen der Volladung der betreffenden Zelle. Wenn Klirrfaktor bei weiter fortgesetztem Laden einer Zelle schließlich konstant bleibt, sich also nicht mehr verschlechtert, hat die Zelle die Volladung erreicht und sollte nicht mehr weiter geladen werden.The degree of distortion of a sinusoidal signal can be quantified in several ways. Examples include the Total Harmonic Distortion Analysis (THDA) or the so-called harmonic distortion, which are known from power electronics or technical acoustics or signal processing. Both methods are based on the detection of the harmonics of a periodic signal, as it is also used in the present method. With the help of z. B. the harmonic distortion and the measurement method described here can be determined with little computational effort even with a large series circuit of multiple battery cells their single full charge. For this purpose, the harmonic distortion of the voltage response is determined continuously for each cell. As soon as it has exceeded a limit that has yet to be determined, this is a sign that the cell in question has been fully charged. If THD continues to remain constant as the cell continues to charge, ie does not deteriorate, the cell has reached full charge and should no longer be charged.
