Abstract
Description
Die Erfindung betrifft eine Batterie für ein Fahrzeug, ein Fahrzeug mit einer solchen Batterie und ein Verfahren einer solchen Batterie in einem Fahrzeug.The invention relates to a battery for a vehicle, a vehicle with such a battery and a method of such a battery in a vehicle.
Im Allgemeinen ist eine Batterie, insbesondere eine Traktionsbatterie für ein Fahrzeug, welches ein Elektrofahrzeug, ein Hybridfahrzeug oder ein mit Brennstoffzellen betriebenes Fahrzeug umfasst, bekannt. Eine solche Batterie dient zur Energieversorgung im Fahrzeug angeordneter elektrischer Verbraucher, die über ein im Fahrzeug angeordnetes Bordnetz mit der Batterie verbunden sind. Zum Schutz des Bordnetzes ist dabei vorgesehen, verschiedene Schalter und Sicherungen einzusetzen. Diese dienen einerseits einem Schutz einer Verkabelung, wobei andererseits z. B. ein sogenannter Ruhestromschalter eingesetzt ist, um einen Ruhestrom des Fahrzeuges zu minimieren.In general, a battery, in particular a traction battery for a vehicle, which comprises an electric vehicle, a hybrid vehicle or a fuel cell-powered vehicle is known. Such a battery is used for power supply in the vehicle arranged electrical consumers, which are connected via an in-vehicle electrical system with the battery. To protect the electrical system is provided to use various switches and fuses. These serve on the one hand to protect a wiring, on the other hand z. B. a so-called quiescent current switch is used to minimize a quiescent current of the vehicle.
Der Erfindung liegt die Aufgabe zugrunde, eine gegenüber dem Stand der Technik verbesserte Batterie, ein verbessertes Verfahren zum Betrieb der Batterie sowie ein Fahrzeug mit einer solchen Batterie anzugeben.The invention has for its object to provide a comparison with the prior art improved battery, an improved method for operating the battery and a vehicle with such a battery.
Die Aufgabe wird erfindungsgemäß hinsichtlich der Batterie durch die in Anspruch 1, hinsichtlich des Fahrzeuges durch die in Anspruch 3 mit einer solchen Batterie und hinsichtlich des Verfahrens durch die in Anspruch 4 angegebenen Merkmale gelöst.The object is achieved with respect to the battery by the in
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Eine erfindungsgemäße Batterie für ein Fahrzeug weist mehrere Polkontakte eines elektrischen Potenzials und eine Schutzschalteranordnung auf, welche mehrere elektrisch parallel geschaltete Schutzschalter umfasst, wobei zumindest einer der Schutzschalter mit einem ersten Polkontakt elektrisch verbunden ist und zumindest ein weiterer Schutzschalter mit zumindest einem weiteren Polkontakt elektrisch verbunden ist, wobei die Schutzschalter separat schaltbar sind.A battery according to the invention for a vehicle has a plurality of pole contacts of an electrical potential and a circuit breaker arrangement, which comprises a plurality of electrically parallel-connected circuit breaker, wherein at least one of the circuit breaker is electrically connected to a first pole contact and at least one further circuit breaker is electrically connected to at least one further pole contact , wherein the circuit breaker are separately switchable.
Dadurch, dass die Schutzschalteranordnung und die mehreren Polkontakte eines elektrischen Potenzials vorgesehen sind, ist es in besonders vorteilhafter Weise möglich, gezielt einen Schutz der Batterie und eine Sicherstellung einer Startfähigkeit der Batterie, insbesondere in Bezug auf eine Tiefenentladung, zu erreichen.Characterized in that the circuit breaker assembly and the plurality of pole contacts of an electrical potential are provided, it is possible in a particularly advantageous manner to achieve targeted protection of the battery and ensuring a startability of the battery, in particular with respect to a deep discharge.

Die Batterie
Dabei ist das Bordnetz B in einen ersten Bordnetz-Bereich B1 und einen zweiten Bordnetz-Bereich B2 unterteilt, wobei der erste Bordnetz-Bereich B1 zur Versorgung der elektrischen Verbraucher im Betrieb des Fahrzeuges und der zweite Bordnetz-Bereich B2 zur Ruhestromversorgung von elektrischen Verbrauchern vorgesehen sind.In this case, the on-board network B is subdivided into a first on-board network area B1 and a second on-board network area B2, the first on-board network area B1 being used to supply the electrical consumers during operation of the vehicle and the second on-board network area B2 to provide standby power to electrical consumers are.
Der zweite Bordnetz-Bereich B2 dient der Versorgung von Verbrauchern mit elektrischer Energie, die im Stillstand des Fahrzeuges, d. h. bei ausgeschalteter Zündung, einen Ruhestrombedarf aufweisen. Beispielsweise kann ein solcher elektrischer Verbraucher eine Steuereinheit des Fahrzeuges sein.The second on-board network area B2 serves to supply consumers with electrical energy that is at standstill of the vehicle, d. H. with ignition off, have a quiescent power requirement. For example, such an electrical load may be a control unit of the vehicle.
In dem vorliegenden Ausführungsbeispiel gemäß
Im Inneren der Batterie
Wird die Zündung des Fahrzeuges abgeschaltet, wird eine erste elektrische Verbindung V1 zwischen dem ersten Polkontakt
Die einen Ruhestrombedarf aufweisenden elektrischen Verbraucher werden über den zweiten Bordnetz-Bereich B2, der über eine zweite elektrische Verbindung V2 mit dem zweiten Polkontakt

Wird ein Ladezustand in Form eines Spannungswertes erfasst, der einen vorgegebenen Grenzwert hinsichtlich der Spannung unterschreitet und der Ladezustand dadurch als kritisch eingestuft werden kann, werden die mit dem zweiten Polkontakt
In Bezug auf die zweite Ausführungsform der Batterie
Um eine Skalierbarkeit dieser oben beschriebenen Lösung zu erhalten, kann die Batterie
Mittels der Anordnung mehrerer Polkontakte
Die Lösung in Form der Anordnung weist eine vergleichsweise geringe Komplexität und einen reduzierten Montageaufwand auf, wobei die Kosten zur Realisierung dieser Lösung im Vergleich gering sind und ein Gewicht der Batterie
