Description
Die vorliegende Erfindung betrifft ein Verfahren zum Laden einer Batterie mit mindestens einem Batteriemodulstrang, bei dem ein Batteriemodul im Batteriemodulstrang eine Koppeleinheit umfasst, sowie eine Batterie, in welcher das erfindungsgemäße Verfahren ausführbar ist. The present invention relates to a method for charging a battery having at least one battery module string, in which a battery module in the battery module string comprises a coupling unit, as well as a battery in which the method according to the invention is executable.
Stand der TechnikState of the art
Es zeichnet sich ab, dass in Zukunft sowohl bei stationären Anwendungen als auch bei Fahrzeugen wie Hybrid- und Elektrofahrzeugen vermehrt Batteriesysteme zum Einsatz kommen werden. Um die für eine jeweilige Anwendung gegebenen Anforderungen an Spannung und zur Verfügung stellbare Leistung erfüllen zu können, werden eine hohe Zahl von Batteriezellen in Serie geschaltet. Da der von einer solchen Batterie bereitgestellte Strom durch alle Batteriezellen fließen muss und eine Batteriezelle nur einen begrenzten Strom leiten kann, werden oft zusätzlich Batteriezellen parallel geschaltet, um den maximalen Strom zu erhöhen. Dies kann entweder durch Vorsehen von mehreren Zellwickeln innerhalb eines Batteriezellengehäuses oder durch externes Verschalten von Batteriezellen geschehen. Dabei ist jedoch problematisch, dass es aufgrund nicht exakt identischer Zellkapazitäten und -spannungen zu Ausgleichsströmen zwischen den parallel geschalteten Batteriezellen kommen kann.It is becoming apparent that in the future, battery systems will increasingly be used in stationary applications as well as in vehicles such as hybrid and electric vehicles. In order to meet the voltage and available power requirements of a particular application, a large number of battery cells are connected in series. Since the power provided by such a battery must flow through all the battery cells and a battery cell can only conduct a limited current, battery cells are often additionally connected in parallel in order to increase the maximum current. This can be done either by providing multiple cell wraps within a battery cell housing or by externally interconnecting battery cells. However, it is problematic that due to not exactly identical cell capacitances and voltages can lead to equalization currents between the parallel-connected battery cells.
Das Prinzipschaltbild einer üblichen elektrischen Antriebseinheit, wie sie beispielsweise in Elektro- und Hybrid-Fahrzeugen oder auch in stationären Anwendungen wie bei der Rotorblattverstellung von Windkraftanlagen zum Einsatz kommt, ist in
Nachteilig bei der in
Für den Austausch eines leeren Batteriesystems an Wechselstationen sind bereits Konzepte aus dem Stand der Technik bekannt. Der Vorteil bei einem Austausch ist, dass ein Fahrer nach dem Tausch seines Batteriesystems in wenigen Minuten bereits wieder mit vollem Batteriesystem weiterfahren kann und er nicht auf das mehrere Stunden dauernde elektrische Aufladen seines Batteriesystems warten muss. Nachteilig ist jedoch, dass zusätzlich zu individuellen Bauformen der Batteriesysteme verschiedener Automobilhersteller und sogar verschiedener Automodelle Wechselkonzepte mit den unterschiedlichsten Steuerungs- und Überwachungstechniken sowie mit unterschiedlichen Konzepten der Leistungselektronik in Batteriesystemen zurechtkommen müssen.Concepts from the prior art are already known for the replacement of an empty battery system at changing stations. The advantage of an exchange is that after replacing the battery system, a driver can drive on with the full battery system in just a few minutes and he does not have to wait for the battery system to charge for several hours. The disadvantage, however, is that in addition to individual designs of the battery systems of different car manufacturers and even different car models have to cope with changing concepts with a variety of control and monitoring techniques and with different concepts of power electronics in battery systems.
Wird dagegen ein leeres Batteriesystem nicht ausgetauscht, sondern aufgeladen, so macht sich die Tatsache bemerkbar, dass darin die einzelnen Batteriezellen in Reihe geschaltet sind und somit beim Laden von demselben Strom durchflossen werden. Wenn alle Batteriezellen gleiche Zustände haben, wird so lange mit einem konstanten Strom geladen, bis die Ladeschlussspannung erreicht ist. If, on the other hand, an empty battery system is not replaced, but charged, the fact becomes apparent that the individual battery cells are connected in series therein and thus flow through the same current during charging. If all battery cells have the same states, charging is carried out with a constant current until the charge end voltage is reached.
Danach wird mit konstanter Spannung weitergeladen, bis der Ladestrom unter einen bestimmten Wert absinkt.Then it is charged with constant voltage until the charging current drops below a certain value.
Offenbarung der Erfindung Disclosure of the invention
Erfindungsgemäß wird daher ein Verfahren zum Laden einer Batterie bereitgestellt. Die Batterie umfasst mindestens einen Batteriemodulstrang mit einer Mehrzahl von in Serie geschalteten Batteriemodulen. Jedes der in Serie geschalteten Batteriemodule umfasst wenigstens eine Batteriezelle, wenigstens eine Koppeleinheit, einen ersten Anschluss und einen zweiten Anschluss und ist dazu ausgebildet, in Abhängigkeit einer Ansteuerung der Koppeleinheit einen von mindestens zwei Schaltzuständen einzunehmen. Hierbei sind in einem ersten Schaltzustand der erste Anschluss und der zweite Anschluss des Batteriemoduls verbunden, und in einem zweiten Schaltzustand ist die wenigstens eine Batteriezelle zwischen den ersten Anschluss und den zweiten Anschluss geschaltet. Das Verfahren umfasst einen Schritt, in welchem ein einzunehmender Schaltzustand in jedem der Batteriemodule festgelegt wird, sowie einen Schritt, in welchem der festgelegte Schaltzustand durch jedes der Batteriemodule in Abhängigkeit der Ansteuerung der Koppeleinheit eingenommen wird.The invention therefore provides a method for charging a battery. The battery includes at least one battery module string having a plurality of battery modules connected in series. Each of the series-connected battery modules comprises at least one battery cell, at least one coupling unit, a first terminal and a second terminal and is designed to occupy one of at least two switching states as a function of a control of the coupling unit. In this case, the first terminal and the second terminal of the battery module are connected in a first switching state, and in a second switching state, the at least one battery cell is connected between the first terminal and the second terminal. The method includes a step in which a switching state to be adopted is set in each of the battery modules, and a step in which the predetermined switching state is assumed by each of the battery modules in response to the driving of the coupling unit.
Wie bereits ausgeführt, ist jedes Batteriemodul dazu ausgebildet, in Abhängigkeit einer Ansteuerung der Koppeleinheit wahlweise den ersten Anschluss und den zweiten Anschluss des Batteriemoduls zu verbinden oder die wenigstens eine Batteriezelle zwischen den ersten Anschluss und den zweiten Anschluss zu schalten. Hierdurch werden zwei verschiedene Schaltzustände definiert. Außerdem kann mindestens ein Batteriemodul dazu ausgebildet sein, die wenigstens eine Batteriezelle zwischen den ersten Anschluss und den zweiten Anschluss zu schalten, wobei eine Polarität der zwischen dem ersten Anschluss und dem zweiten Anschluss anliegenden Spannung in Abhängigkeit einer Ansteuerung der Koppeleinheit wählbar ist. Hierdurch entstehen insgesamt drei Schaltzustände.As already explained, each battery module is designed to selectively connect the first connection and the second connection of the battery module or to switch the at least one battery cell between the first connection and the second connection, depending on activation of the coupling unit. This defines two different switching states. In addition, at least one battery module can be configured to switch the at least one battery cell between the first terminal and the second terminal, wherein a polarity of the voltage applied between the first terminal and the second terminal voltage in response to a control of the coupling unit is selectable. This results in a total of three switching states.
Durch das erfindungsgemäße Verfahren wird das Laden der Batterie beziehungsweise der einzelnen Batteriemodule vereinfacht. Insbesondere ist es möglich, die verschiedenen Batteriemodule gleichzeitig aus einer Spannungsquelle heraus zu laden. Hierbei können die Batteriemodule auch Batteriezellen unterschiedlicher Kapazität und unterschiedlicher Ladezustände umfassen. Außerdem werden eine kürzere Ladezeit und geringere Verluste beim Laden erreicht.The inventive method, the charging of the battery or the individual battery modules is simplified. In particular, it is possible to simultaneously charge the different battery modules from a voltage source. In this case, the battery modules may also include battery cells of different capacity and different states of charge. In addition, a shorter charging time and lower charging losses are achieved.
Am Anfang eines Ladevorgangs wird üblicherweise durch mindestens eins der Batteriemodule und praktischerweise durch alle Batteriemodule der zweite Schaltzustand eingenommen, in welchem der durch das jeweilige Batteriemodul fließende Strom die zwischen den Anschlüssen geschaltete Batteriezelle oder -zellen aufzuladen vermag.At the beginning of a charging process, the second switching state is usually assumed by at least one of the battery modules and, conveniently, by all battery modules, in which the current flowing through the respective battery module is able to charge the battery cell or cells connected between the terminals.
Bevorzugt ist, dass der einzunehmende Schaltzustand in jedem der Batteriemodule durch ein Steuergerät festgelegt wird und die Koppeleinheiten durch das Steuergerät angesteuert werden.It is preferred that the switching state to be adopted in each of the battery modules is determined by a control unit and the coupling units are controlled by the control unit.
Typischerweise wird ein Ladegerät an zwei Ladeanschlüsse der Batterie angeschlossen, und diese über die zwei Ladeanschlüsse aufgeladen, bevorzugt mit einer konstanten Ladespannung. Typically, a charger is connected to two charging terminals of the battery, and these charged via the two charging ports, preferably with a constant charging voltage.
In einer weiteren bevorzugten Ausführung wird durch mindestens eins der Batteriemodule der erste Schaltzustand eingenommen, wenn eine zwischen dem ersten Anschluss und dem zweiten Anschluss des Batteriemoduls anliegende Spannung einen vorbestimmten Spannungsschwellenwert überschreitet. Da in dem ersten Schaltzustand der erste Anschluss und der zweite Anschluss des Batteriemoduls verbunden sind, wird letzteres somit überbrückt und nicht weiter aufgeladen. Bevorzugt ist, dass der Ladevorgang beendet wird, sobald durch alle Batteriemodule der erste Schaltzustand eingenommen wird.In a further preferred embodiment, the first switching state is assumed by at least one of the battery modules when a voltage applied between the first terminal and the second terminal of the battery module exceeds a predetermined voltage threshold. Since in the first switching state of the first terminal and the second terminal of the battery module are connected, the latter is thus bridged and not charged further. It is preferred that the charging process is terminated as soon as the first switching state is assumed by all battery modules.
Ein weiterer Aspekt der Erfindung betrifft eine Batterie, bevorzugt eine Lithium-Ionen-Batterie, welche mindestens einen Batteriemodulstrang mit den oben beschriebenen Eigenschaften umfasst, so dass das erfindungsgemäße Verfahren in der Batterie ausgeführt werden kann. Another aspect of the invention relates to a battery, preferably a lithium-ion battery, which comprises at least one battery module string having the properties described above, so that the inventive method can be performed in the battery.
Ein weiterer Aspekt der Erfindung betrifft ein Steuergerät, welches dazu ausgebildet ist, einzunehmende Schaltzustände in jedem der Batteriemodule der erfindungsgemäßen Batterie festzulegen und die Koppeleinheiten in der Batterie anzusteuern derart, dass das erfindungsgemäße Verfahren ausgeführt werden kann. In einer bevorzugten Ausführungsform ist das Steuergerät Teil der erfindungsgemäßen Batterie. A further aspect of the invention relates to a control device which is designed to set switching states to be adopted in each of the battery modules of the battery according to the invention and to control the coupling units in the battery such that the method according to the invention can be carried out. In a preferred embodiment, the control unit is part of the battery according to the invention.
Es wird zudem ein Kraftfahrzeug mit einem elektrischen Antriebsmotor zum Antreiben des Kraftfahrzeuges und einer mit dem elektrischen Antriebsmotor verbundenen erfindungsgemäßen Batterie angegeben.In addition, a motor vehicle is specified with an electric drive motor for driving the motor vehicle and a battery according to the invention connected to the electric drive motor.
