Description
Die vorliegende Erfindung betrifft eine Batterie mit wenigstens einem Batteriemodulstrang, ein Antriebssystem für einen elektrischen Antriebsmotor mit der erfindungsgemäßen Batterie sowie ein Kraftfahrzeug mit dem erfindungsgemäßen Antriebssystem. The present invention relates to a battery with at least one battery module string, a drive system for an electric drive motor with the battery according to the invention and a motor vehicle with the drive system according to the invention.
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 both in stationary applications and 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 eines üblichen elektrischen Antriebssystems, wie es beispielsweise in Elektro- und Hybrid-Fahrzeugen oder auch in stationären Anwendungen wie bei der Rotorblattverstellung von Windkraftanlagen zum Einsatz kommt, ist in
Die Serienschaltung einer hohen Zahl von Batteriezellen bringt neben der hohen Gesamtspannung das Problem mit sich, dass die gesamte Batterie ausfällt, wenn eine einzige Batteriezelle ausfällt, weil der Batteriestrom wegen der Serienschaltung in allen Batteriezellen fließen können muss. Ein solcher Ausfall der Batterie kann zu einem Ausfall des Gesamtsystems führen. Bei einem Elektrofahrzeug führt ein Ausfall der Antriebsbatterie zu einem so genannten Liegenbleiber, bei anderen Vorrichtungen wie zum Beispiel der Rotorblattverstellung bei Windkraftanlagen bei starkem Wind kann es zu unerwünschten Situationen kommen. Daher ist eine hohe Zuverlässigkeit der Batterie vorteilhaft. Gemäß Definition bedeutet der Begriff „Zuverlässigkeit“ die Fähigkeit eines Systems, für eine vorgegebene Zeit korrekt zu arbeiten.The series connection of a high number of battery cells, in addition to the high total voltage involves the problem that the entire battery fails if a single battery cell fails because the battery power must be able to flow in all battery cells because of the series connection. Such a failure of the battery can lead to a failure of the entire system. In an electric vehicle, a failure of the drive battery leads to a so-called lying down, in other devices such as the rotor blade adjustment in wind turbines in strong winds, there may be undesirable situations. Therefore, high reliability of the battery is advantageous. By definition, the term "reliability" means the ability of a system to operate correctly for a given time.
Offenbarung der ErfindungDisclosure of the invention
Erfindungsgemäß wird daher eine Batterie mit wenigstens einem Batteriemodulstrang eingeführt, bei der wenigstens ein Batteriemodulstrang eine Mehrzahl von in Serie geschalteten Batteriemodulen umfasst. Die Batterie ist bevorzugt eine Lithium-Ionen-Batterie. Jedes Batteriemodul umfasst wenigstens eine Batteriezelle und eine Koppeleinheit. Die wenigstens eine Batteriezelle ist zwischen einen ersten Eingang und einen zweiten Eingang der Koppeleinheit geschaltet. Die Koppeleinheit ist ausgebildet, auf ein erstes Steuersignal hin die wenigstens eine Batteriezelle zwischen ein erstes Terminal des Batteriemoduls und ein zweites Terminal des Batteriemoduls zu schalten und auf ein zweites Steuersignal hin das erste Terminal mit dem zweiten Terminal zu verbinden. An dem Batteriemodulstrang ist ein Mittelabgriff angeordnet, mit welchem ein Potential an einer Verbindung zwischen zwei Batteriemodulen abgreifbar ist. Hierbei sind die zwei Batteriemodule in der Serienschaltung benachbart. According to the invention, therefore, a battery having at least one battery module string is introduced, in which at least one battery module string comprises a plurality of series-connected battery modules. The battery is preferably a lithium-ion battery. Each battery module comprises at least one battery cell and a coupling unit. The at least one battery cell is connected between a first input and a second input of the coupling unit. The coupling unit is configured, in response to a first control signal, to switch the at least one battery cell between a first terminal of the battery module and a second terminal of the battery module and to connect the first terminal to the second terminal in response to a second control signal. At the battery module string a center tap is arranged, with which a potential at a connection between two battery modules can be tapped. Here, the two battery modules are adjacent in the series circuit.
Der Mittelabgriff kann in einer Mitte der Mehrzahl von in Serie geschalteten Batteriemodulen angeordnet sein.The center tap may be disposed in a center of the plurality of series-connected battery modules.
An den Batteriemodulstrang können mehrere Mittelabgriffe angeordnet sein, mit welchen ein Potential an einer Verbindung zwischen jeweils zwei Batteriemodulen abgreifbar ist. Hierbei ist jeder der Mittelabgriffe jeweils einem Paar von in der Serienschaltung benachbarten Batteriemodulen zugeordnet. Bevorzugt ist dabei, dass die Mittelabgriffe den Batteriemodulstrang derart unterteilen, dass jede Unterteilung des Batteriemodulstrangs eine gleiche Anzahl an Batteriemodulen umfasst. Die Batterie kann eine Steuereinheit umfassen, welche dazu ausgebildet ist, das erste Steuersignal an eine erste variable Anzahl von Batteriemodulen des wenigstens einen Batteriemodulstranges und das zweite Steuersignal an die verbleibenden Batteriemodule des wenigstens einen Batteriemodulstranges auszugeben und so eine Ausgangsspannung des wenigstens einen Batteriemodulstranges der Batterie variabel einzustellen.Several center taps may be arranged on the battery module string, with which a potential can be tapped off at a connection between in each case two battery modules. In this case, each of the center taps is assigned in each case to a pair of battery modules which are adjacent in the series connection. It is preferred that the center taps subdivide the battery module string such that each subdivision of the battery module string comprises an equal number of battery modules. The battery may include a control unit which is configured to output the first control signal to a first variable number of battery modules of the at least one battery module line and the second control signal to the remaining battery modules of the at least one battery module line and thus an output voltage of the at least one battery module line of the battery variable adjust.
Die Koppeleinheit kann einen Ausgang aufweisen und dazu ausgebildet sein, auf das erste Steuersignal hin entweder den ersten Eingang oder den zweiten Eingang mit dem Ausgang zu verbinden. Dabei ist der Ausgang mit dem ersten Terminal oder mit dem zweiten Terminal des Batteriemoduls verbunden.The coupling unit may have an output and be configured to connect to the first control signal either the first input or the second input to the output. The output is connected to the first terminal or to the second terminal of the battery module.
Ein weiterer Aspekt der Erfindung betrifft ein Antriebssystem für einen elektrischen Antriebsmotor. Das Antriebssystem umfasst eine Batterie mit einem Batteriemodulstrang mit mehreren Mittelabgriffen und einem Multilevel-Inverter. Die Eingänge des Multilevel-Inverters sind dabei mit den Mittelabgriffen verbunden.Another aspect of the invention relates to a drive system for an electric drive motor. The drive system includes a battery having a battery module string with multiple center taps and a multilevel inverter. The inputs of the multilevel inverter are connected to the center taps.
Ein weiterer Aspekt der Erfindung betrifft ein Kraftfahrzeug mit einem elektrischen Antriebsmotor zum Antreiben des Kraftfahrzeuges. Der elektrische Antriebsmotor ist mit dem erfindungsgemäßen Antriebssystem verbunden.Another aspect of the invention relates to a motor vehicle with an electric drive motor for driving the motor vehicle. The electric drive motor is connected to the drive system according to the invention.
