Description
Die vorliegende Erfindung betrifft eine Batterie für ein elektrisches Kraftfahrzeug mit einer Vielzahl an seriell zueinander geschalteten Batteriezellen nach dem Oberbegriff des unabhängigen Vorrichtungsanspruches.The present invention relates to a battery for an electric motor vehicle with a plurality of serially connected battery cells according to the preamble of the independent device claim.
Moderne Kraftfahrzeuge, insbesondere elektrisch angetriebene Kraftfahrzeuge oder Hybridfahrzeuge, weisen Batterien auf, die aus mehreren Batteriezellen bestehen. Solche Batterien erfordern einen Balancer bzw. einen Ausgleichsregler, der eine gleichmäßige elektrische Ladungsverteilung in den Batteriezellen innerhalb der Batterien gewährleisten soll, deren Ladungen sich durch Fertigungstoleranzen oder durch Alterungserscheinungen unterscheiden können. Meistens werden hierzu kostspielige, kompliziert aufgebaute integrierte Schaltungen, so gen. ASICs verwendet. Dies macht nicht nur den Aufbau der Batterien kompliziert und kostspielig, sondern erhöht den erforderlichen Bauraum für einen Balancing. Zudem sind solche ASICs anwendungsspezifische Bauteile, die keine Änderungen oder Anpassungen zulassen und die nicht mit unterschiedlichen Batterien kompatibel sind. Meistens eignen sich solche bekannten Batterien nicht für einen modularen Aufbau.Modern motor vehicles, in particular electrically driven motor vehicles or hybrid vehicles, have batteries that consist of several battery cells. Such batteries require a balancer which is intended to ensure a uniform electrical charge distribution in the battery cells within the batteries, the charges of which may differ due to manufacturing tolerances or aging phenomena. In most cases expensive, complex integrated circuits, so called ASICs are used. This not only makes the construction of the batteries complicated and costly, but also increases the space required for balancing. In addition, such ASICs are application specific components that do not allow for changes or adjustments and are not compatible with different batteries. In most cases, such known batteries are not suitable for a modular design.
Der Erfindung liegt daher die Aufgabe zugrunde, mindestens einen aus dem Stand der Technik bekannten Nachteil bei einer Batterie für ein elektrisches Kraftfahrzeug zu überwinden. Insbesondere ist es Aufgabe der vorliegenden Erfindung, eine Batterie für ein elektrisches Kraftfahrzeug bereitzustellen, sei es für ein voll elektrisches oder ein Hybridfahrzeug, welche einfach aufgebaut und kostengünstig ist, welche wenig Bauteile aufweist, welche den notwendigen Bauraum für einen Balancing reduziert, welche eine gleichmäßige elektrische Ladungsverteilung in allen Batteriezellen innerhalb der Batterie ermöglicht, welche zuverlässig im Betrieb ist und welche einen hohen Wirkungsgrad sowie eine hohe Lebensdauer aufweist. Außerdem soll die erfindungsgemäße Batterie für einen modularen Aufbau geeignet sein.The invention is therefore based on the object to overcome at least one known from the prior art disadvantage of a battery for an electric motor vehicle. In particular, it is an object of the present invention to provide a battery for an electric motor vehicle, be it for a fully electric or a hybrid vehicle, which is simple and inexpensive, which has few components, which reduces the space required for a balancing, which is a uniform allows electrical charge distribution in all battery cells within the battery, which is reliable in operation and which has a high efficiency and a long life. In addition, the battery according to the invention should be suitable for a modular design.
Die vorliegende Aufgabe wird durch eine Batterie mit den Merkmalen des unabhängigen Anspruches 1, insbesondere aus dem kennzeichnenden Teil, gelöst. In den abhängigen Ansprüchen sind bevorzugte Weiterbildungen der Erfindung aufgeführt.The present object is achieved by a battery with the features of
Die Erfindung stellt eine Batterie für ein elektrisches Kraftfahrzeug mit einer Vielzahl an seriell zueinander geschalteten Batteriezellen bereit, wobei parallel zu jeder Batteriezelle jeweils ein Balancing-Pfad zum Laden der Batterie zugeschaltet ist. Hierzu ist es erfindungsgemäß vorgesehen, dass der Balancing-Pfad einen Widerstand und eine erste Zenerdiode aufweist.The invention provides a battery for an electric motor vehicle with a plurality of serially connected battery cells, wherein parallel to each battery cell in each case a balancing path is switched to charge the battery. For this purpose, it is provided according to the invention that the balancing path has a resistor and a first zener diode.
Die erfindungsgemäße Batterie kann sich unterschiedliche Technologien zunutze machen und aus unterschiedlichen Materialien ausgebildet sein. Die erfindungsgemäße Batterie kann sowohl für reine Elektrofahrzeuge, als auch für Hybridfahrzeuge als eine Traktionsbatterie verwendet werden. Gleichwohl kann die erfindungsgemäße Batterie als eine LV-Batterie zum Versorgen elektrischer Verbraucher in unterschiedlichen Kraftfahrzeugen, sogar in reinen Verbrennungsfahrzeugen, verwendet werden. Zudem kann die erfindungsgemäße Batterie zur Energierückgewinnung, bspw. aus einer Bremsenergie, verwendet werden. Die erfindungsgemäße Batterie kann modular aufgebaut sein und in jedem separat aufbaubaren und separat anschließbaren Modul jeweils eine Vielzahl an seriell zueinander geschalteten Batteriezellen aufweisen. Dabei kann die erfindungsgemäße Batterie wiederaufladbare Batteriezellen aufweisen und somit als ein Akkumulator ausgebildet sein.The battery according to the invention can make use of different technologies and be made of different materials. The battery according to the invention can be used as a traction battery both for pure electric vehicles and for hybrid vehicles. However, the battery of the present invention can be used as a LV battery for supplying electric consumers in various automobiles, even in pure-vehicle combustion vehicles. In addition, the battery according to the invention for energy recovery, for example. From a braking energy can be used. The battery according to the invention may have a modular structure and in each separately buildable and separately connectable module each have a plurality of serially connected to each other battery cells. In this case, the battery according to the invention may comprise rechargeable battery cells and thus be designed as an accumulator.
Die erfindungsgemäße Batterie zeichnet sich dadurch aus, dass die Batterie jeweils einen integrierten Balancing-Pfad für jede Batteriezelle zum Laden der Batterie aufweist. Somit entfällt der Bedarf, kostspielige, kompliziert aufgebaute anwendungsspezifische integrierte Schaltungen, so gen. ASICs für einen Balancing der Batterie zu verwenden. Vielmehr kann der Balancing innerhalb der Batterie, vorzugsweise passiv, ausgeführt werden. Somit kann nicht nur der Bauraum für die Batterie, inklusive der integrierten Balancing-Pfade, effizient ausgenutzt und reduziert werden, sondern auch der Balancing effizient und sicher ausgeführt werden. Dabei kann die Zenerdiode eine erste Durchbruchsspannung aufweisen, die einer Vollladung einer Batteriezelle entspricht, sodass nach dem Erreichen einer Vollladung der Batteriezelle, die Zenerdiode den Strom an der Batteriezelle vorbei durchlassen kann, der am Widerstand in Wärme umgewandelt werden kann, ohne die Batteriezelle zu überladen. Die Lebensdauer und der Wirkungsgrad der Batterie können dadurch erheblich erhöht werden. Insbesondere bei modular aufgebauten Batterien bringt die Erfindung erhebliche Vorteile mit sich, da die Batterien einfach und bequem zusammengestellt werden können, die einzelnen Module problemlos ausgetauscht werden können, ohne eine neue separate ASIC bestellen zu müssen. Vielmehr kann eine solche modulare Batterie mithilfe der Erfindung als ein Baukasten gehandhabt werden, wobei jedes Modul und jede Batteriezelle darin zuverlässig und sicher vor Überladungen geschützt wird, wodurch eine gleichmäßige Ladungsverteilung innerhalb der Batterie realisiert wird.The battery according to the invention is characterized in that the battery has an integrated balancing path for each battery cell for charging the battery. Thus, there is no need to use costly, intricately designed, application specific integrated circuits, ASICs, to balance the battery. Rather, the balancing can be performed within the battery, preferably passive. Thus, not only the space for the battery, including the integrated balancing paths, can be efficiently utilized and reduced, but also the balancing can be carried out efficiently and safely. In this case, the Zener diode may have a first breakdown voltage corresponding to a full charge of a battery cell, so that after reaching a full charge of the battery cell, the Zener diode can pass the current past the battery cell, which can be converted into heat at the resistor without overloading the battery cell , The life and the efficiency of the battery can be significantly increased. Especially with modular batteries, the invention brings considerable advantages, since the batteries can be easily and conveniently assembled, the individual modules can be easily replaced without having to order a new separate ASIC. Rather, such a modular battery can be handled by the invention as a kit, wherein each module and each battery cell is reliably and safely protected from overcharging therein, whereby a uniform charge distribution is realized within the battery.
Ferner kann die Erfindung bei einer Batterie vorsehen, dass die erste Zenerdiode im Balancing-Pfad eine erste Durchbruchspannung aufweisen kann, wobei die erste Durchbruchspannung einer Spannung der geladenen Batteriezelle bzw. Vollladung entspricht. Somit wird ermöglicht, dass die Batteriezelle vollgeladen, aber nicht überladen wird.Furthermore, the invention may provide for a battery that the first Zener diode in Balancing path may have a first breakdown voltage, wherein the first breakdown voltage corresponds to a voltage of the charged battery cell or full charge. This allows the battery cell to be fully charged but not overcharged.
Weiterhin kann die Erfindung bei einer Batterie vorsehen, dass parallel zu jeder Batteriezelle jeweils ein Überspannungsschutzpfad zugeschaltet sein kann. Somit können die Batterie und innerhalb der Batterie die einzelnen Batteriezellen zuverlässig vor Überspannung geschützt werden. Der Überspannungsschutzpfad kann für den Notfall vorgesehen sein, wenn der Balancing-Pfad überlastet wird und nicht alle überschüssige Energie in Wärmeenergie umwandeln kann.Furthermore, the invention can provide for a battery that an overvoltage protection path can be connected in parallel to each battery cell. Thus, the battery and within the battery, the individual battery cells can be reliably protected from overvoltage. The overvoltage protection path may be provided for emergency when the balancing path becomes overloaded and can not convert all excess energy into heat energy.
Des Weiteren kann die Erfindung bei einer Batterie vorsehen, dass der Überspannungsschutzpfad eine zweite Zenerdiode aufweisen kann. Somit kann mit einfachen und günstigen Mitteln, eine weitere Spannung, eine so gen. Überspannung festgelegt werden, die nicht überschritten werden kann. Somit kann die Batterie zuverlässig vor Überspannungen geschützt werden.Furthermore, in a battery, the invention may provide that the overvoltage protection path may comprise a second zener diode. Thus, with simple and cheap means, another voltage, so gen. Overvoltage can be set, which can not be exceeded. Thus, the battery can be reliably protected against overvoltages.
Zudem kann die Erfindung bei einer Batterie vorsehen, dass die zweite Zenerdiode im Überspannungsschutzpfad eine zweite Durchbruchspannung aufweisen kann, wobei die zweite Durchbruchspannung einer Überladespannung im Balancing-Pfad entspricht. Somit kann der Überspannungsschutzpfad im Notfall aktiviert werden, wenn der Balancing-Pfad überlastet ist.In addition, the invention may provide for a battery that the second Zener diode in the overvoltage protection path may have a second breakdown voltage, wherein the second breakdown voltage corresponds to an overcharge voltage in the balancing path. Thus, the overvoltage protection path can be activated in an emergency if the balancing path is overloaded.
Außerdem kann die Erfindung bei einer Batterie vorsehen, dass die Überladespannung im Balancing-Pfad sich aus einer Spannung der geladenen Batteriezelle und einem Spannungsabfall am Widerstand zusammensetzen kann. Somit kann eine Hierarchie geschaffen werden, die bei einer Spannung in der Batteriezelle unterhalb einer Vollladung ein weiteres Laden der Batteriezelle ermöglicht, die bei einer Spannung in der Batteriezelle oberhalb der Vollladung einen Balancing einleitet und die in einem Notfall bei einer Überspannung einen Durchfluss des Stroms an der Batteriezelle und am Balancing-Pfad vorbei sicherstellt.In addition, the invention may provide for a battery that the overcharge voltage in the balancing path can be composed of a voltage of the charged battery cell and a voltage drop across the resistor. Thus, a hierarchy can be provided which allows for a voltage in the battery cell below a full charge further charging of the battery cell, which initiates a balancing at a voltage in the battery cell above the full charge and in an emergency at an overvoltage flow of the current ensuring the battery cell and the balancing path over.

Dabei können die in den Ansprüchen und in der Beschreibung erwähnten Merkmale jeweils einzeln für sich oder in beliebiger Kombination erfindungswesentlich sein.
