Description
Temperiereinrichtung zum Temperieren eines Batteriezellenmoduls einer elektri schen Energieversorgungseinrichtung Tempering device for tempering a battery cell module of an electrical energy supply device rule
Die Erfindung betrifft eine Temperiereinrichtung zum Temperieren eines Batterie- zellenmoduls einer elektrischen Energieversorgungseinrichtung sowie eine elekt- rische Energieversorgungseinrichtung mit einer solchen Temperiereinrichtung.The invention relates to a tempering device for tempering a battery cell module of an electrical power supply device and an electrical power supply device with such a tempering device.
Die Erfindung betrifft auch eine Elektro-oder Hybridfahrzeug mit einer solchen elektrischen Energieversorgungseinrichtung. The invention also relates to an electric or hybrid vehicle having such an electrical power supply device.
Batteriezellenmodule auf Basis von Lithium-Ionen-Batterien müssen bei der Ver- wendung in Kraftfahrzeugen zwingend gekühlt und beheizt werden, um die ein- zelnen Batteriezellen vor zu schneller Alterung zu schützen. Für Elektrofahrzeuge werden teilweise hohe Reichweiten und Schnellladefähigkeiten gefordert. Insbe- sondere bei elektrischen Energiespeichern führt dies zu sehr großen Batteriege- häusen/-modulen. When used in motor vehicles, battery cell modules based on lithium-ion batteries must be cooled and heated to protect the individual battery cells from aging too quickly. For electric vehicles sometimes high ranges and fast charging capabilities are required. In particular with electric energy storage devices, this leads to very large battery housings / modules.
Es gilt dabei, die vom Batteriezellenmodul erzeugte Abwärme möglichst direkt aufzunehmen, um die bei hohen Lade- und Entladeraten auftretenden großen Wärmemengen abführen zu können. Hierzu sind Temperiereinrichtungen be- kannt, bei welchen in einem Fluidkreislauf ein Fluid zirkuliert wird, welches ther- misch mit dem zu temperierenden Batteriezellenmodul verbunden ist. Auf diese Weise kann das Fluid die vom Batteriezellenmodul erzeugte Wärme aufnehmen, wenn dieses gekühlt werden soll, aber auch Wärme an das Batteriezellenmodul abgeben, wenn das Batteriezellenmodul beheizt werden soll. Über einen im Flu- idkreislauf angeordneten Wärmetauscher kann seinerseits das Fluid temperiert werden. Um einen guten thermischen Kontakt des Fluids mit dem zur temperierenden Zel- le sicherzustellen, ist es üblich, das Batteriezellenmodul direkt in den Fluidkreis lauf zu integrieren, sodass es von dem Fluid somit teilweise umströmt wird. Da die mit dem Fluid thermisch in Kontakt stehenden Komponenten des Batteriezellen- moduls wie etwa ein Modulgehäuse aus einem elektrisch leitenden Material gefer- tigt sind, ist es von hoher Bedeutung, dass über das typischerweise elektrisch- nicht leitende Fluid kein elektrischer Kurzschluss durch im Fluid enthaltene, elektrisch leitende Verunreinigungen erzeugt werden kann. It is important to record the waste heat generated by the battery cell module as directly as possible in order to dissipate the large amounts of heat occurring at high charging and discharging rates can. For this purpose, tempering devices are known, in which a fluid is circulated in a fluid circuit, which is thermally connected to the battery cell module to be tempered. In this way, the fluid can absorb the heat generated by the battery cell module when it is to be cooled, but also deliver heat to the battery cell module when the battery cell module is to be heated. In turn, the fluid can be tempered via a heat exchanger arranged in the fluid circuit. In order to ensure good thermal contact of the fluid with the cell to be tempered, it is customary to integrate the battery cell module directly into the fluid circuit, so that it is thus partially surrounded by the fluid. Since the components of the battery cell module that are in thermal contact with the fluid, such as a module housing, are made of an electrically conductive material, it is of great importance that there is no electrical short circuit through the fluid, which is typically electrically non-conductive , electrically conductive impurities can be generated.
Es ist daher eine Aufgabe der vorliegenden Erfindung, eine verbesserte Ausfüh- rungsform für eine Temperiereinrichtung zu schaffen, welche dieser Anforderung gerecht wird. It is therefore an object of the present invention to provide an improved embodiment for a tempering device, which meets this requirement.
Diese Aufgabe wird durch den Gegenstand der unabhängigen Patentansprüche gelöst. Bevorzugte Ausführungsformen sind Gegenstand der abhängigen Pa- tentansprüche. This object is solved by the subject matter of the independent patent claims. Preferred embodiments are the subject of the dependent patent claims.
Grundidee der Erfindung ist demnach, im Fluidkreislauf eine Sensoreinrichtung anzuordnen, welche im Fluid gegebenenfalls vorhandene Verunreinigungen, typi- scherweise in Form von Schmutzpartikeln, detektieren kann. Werden von der Sensoreinrichtung solche Verunreinigungen erkannt, so wird das Fluid durch eine im Fluidkreislauf vorgesehene Filtereinrichtung geführt, welche besagte Verunrei- nigungen aus dem Fluid ausfiltert. Auf diese Weise wird sichergestellt, dass keine elektrisch leitenden Schmutzpartikel im Fluid verbleiben und in dem zur temperie- renden Batteriezellenmodul einen elektrischen Kurzschluss verursachen können. The basic idea of the invention is accordingly to arrange a sensor device in the fluid circuit which can detect any impurities present in the fluid, typically in the form of dirt particles. If such impurities are detected by the sensor device, the fluid is guided through a filter device provided in the fluid circuit, which filters out said impurities from the fluid. In this way, it is ensured that no electrically conductive dirt particles remain in the fluid and can cause an electrical short circuit in the battery cell module to be tempered.
Erfindungswesentlich an der hier vorgestellten Temperiereinrichtung ist dabei ein im Fluidkreislauf vorgesehener Bypass, über welchen das Fluid an der Filterein- richtung vorbeigeführt werden kann, solange von der Sensoreinrichtung keine Schmutzpartikel bzw. nur eine Konzentration unterhalb eines festgelegten Grenz- werts detektiert werden. Auf diese Weise wird ein unnötig hoher Druckverlust im Fluid, hervorgerufen durch die Durchströmung der Filtereinrichtung, vermieden. Dies wiederum führt zu einer verbesserten Effizienz der Temperiereinrichtung beim Wärmeaustausch mit dem zur temperierenden Batteriezellenmodul. Besag- ter Bypass kann dabei im Bedarfsfall mittels einer umschaltbaren Ventileinrich- tung realisiert werden, über welche das Fluid an der Filtereinrichtung vorbei gelei- tet werden kann. Im Ergebnis wird somit eine Temperiereinrichtung mit hoher thermischer Effizienz geschaffen, in welcher das Vorhandensein von Schmutz- partikeln in dem durch den Fluidkreislauf zirkulierenden Fluid weitgehend oder sogar vollständig ausgeschlossen ist. Essential to the invention of the temperature control device presented here is a bypass provided in the fluid circuit, via which the fluid can be conducted past the filter device, as long as no sensor is provided by the sensor device Dirt particles or only a concentration below a specified limit value can be detected. In this way, an unnecessarily high pressure loss in the fluid caused by the flow through the filter device is avoided. This in turn leads to an improved efficiency of the tempering device during heat exchange with the tempering battery cell module. If required, said bypass can be realized by means of a switchable valve device, via which the fluid can be conducted past the filter device. As a result, a tempering device with high thermal efficiency is thus created, in which the presence of dirt particles in the fluid circulating through the fluid circuit is largely or even completely excluded.
Eine erfindungsgemäße Temperiereinrichtung zum Temperieren eines Batterie- zellenmoduls eines Kraftfahrzeugs umfasst einen Fluidkreislauf, in welchem ein Fluid zum Temperieren des Batteriezellenmoduls zirkuliert. Im Fluidkreislauf ist eine Fördereinrichtung zum Antreiben bzw. Fördern des Fluids angeordnet. Fer- ner ist im Fluidkreislauf eine Filtereinrichtung zum Reinigen des Fluids angeord- net. Erfindungswesentlich ist dabei ein im Fluidkreislauf vorgesehener Filterby- pass, welcher an der im Fluidkreislauf angeordneten Filtereinrichtung vorbeiführt. Mittels einer Ventileinrichtung kann eingestellt werden, ob das Fluid durch die Fil tereinrichtung hindurch oder über den Filterbypass an der Filtereinrichtung vorbei geführt werden soll. Flierzu umfasst die Temperiereinrichtung eine im Fluidkreis- lauf angeordnete Sensoreinrichtung, mittels welcher im zirkulierenden Fluid das Vorhandensein von Verunreinigungen, insbesondere in Form von Schmutzparti- keln, detektiert werden kann. Besonders bevorzugt ist die Sensoreinrichtung der- art ausgebildet, dass sie einen Verschmutzungsgrad des Fluids detektiert. Erfin- dungsgemäß besitzt die Temperiereinrichtung eine mit der Ventileinrichtung und mit der Sensoreinrichtung zusammenwirkende Steuerungs- /Regelungseinrichtung. Die Steuerungs-/Regelungseinrichtung ist die derart ein- gerichtet/programmiert, dass sie in Abhängigkeit von dem detektierten Ver- schmutzungsgrad die Ventileinrichtung zwischen einer Filter-Stellung und einer Bypass-Stellung verstellt. In der Filterstellung wird das Fluid vollständig durch die Filtereinrichtung geführt. In der Bypass-Stellung wird das Fluid vollständig durch den Filterbypass geführt. Bevorzugt kann die Ventileinrichtung auch in mindes- tens eine Zwischenstellung verstellt werden, in welcher eine erste Teilmenge des Fluid durch die Filtereinrichtung und eine dazu komplementäre, zweite Teilmenge des Fluid durch den Filterbypass geführt wird. Besonders bevorzugt kann in die- sem Fall mittels der Ventileinrichtung das Verhältnis zwischen erster und zweiter Teilmenge variiert und auch gezielt eingestellt werden. A tempering device according to the invention for controlling the temperature of a battery cell module of a motor vehicle comprises a fluid circuit in which a fluid circulates for controlling the temperature of the battery cell module. In the fluid circuit, a conveyor for driving or conveying the fluid is arranged. Furthermore, a filter device for purifying the fluid is arranged in the fluid circuit. Essential to the invention is a filter bypass provided in the fluid circuit, which bypasses the filter device arranged in the fluid circuit. By means of a valve device can be adjusted, whether the fluid through the tereinrichtung Tereinrichtung or over the filter bypass to the filter device to be passed over. The tempering device also includes a sensor device arranged in the fluid circuit, by means of which the presence of impurities, in particular in the form of dirt particles, can be detected in the circulating fluid. Particularly preferably, the sensor device is designed such that it detects a degree of contamination of the fluid. According to the invention, the tempering device has a control / regulating device cooperating with the valve device and with the sensor device. The control / regulation device is the one such directed / programmed to adjust the valve means between a filter position and a bypass position depending on the degree of contamination detected. In the filter position, the fluid is passed completely through the filter device. In the bypass position, the fluid is completely routed through the filter bypass. Preferably, the valve device can also be adjusted in at least one intermediate position, in which a first subset of the fluid is passed through the filter device and a complementary, second subset of the fluid through the filter bypass. In this case, the ratio between the first and second subset can be varied and also adjusted in a targeted manner by means of the valve device.
Gemäß einer bevorzugten Ausführungsform umfasst die Sensoreinrichtung zur Detektion der Verunreinigungen wenigstens einen optischen und/oder elektri schen und/oder akustischen Sensor. Ein optischer Sensor kann durch Detektion des durch das Fluid transmittierten Lichts erfolgen. Insbesondere ist es denkbar, dass von einem solchen optischen Sensor die Lichtbrechung oder Lichtschwä- chung des durch das Fluid transmittierten Lichts detektiert wird. Ein akustischer Sensor ermöglicht den Nachweis von Schmutzpartikel durch Auswertung der das Fluid durchdringenden Schallwellen. Wird ein elektrischer Sensor verwendet, so bietet es sich an, die elektrische Leitfähigkeit, die Induktivitäten oder andere elektrische Eigenschaften des Fluid zu detektieren. According to a preferred embodiment, the sensor device for detecting the contaminants comprises at least one optical and / or electrical rule and / or acoustic sensor. An optical sensor can be made by detecting the light transmitted through the fluid. In particular, it is conceivable that the light refraction or light weakening of the light transmitted through the fluid is detected by such an optical sensor. An acoustic sensor enables the detection of dirt particles by evaluating the sound waves penetrating the fluid. If an electrical sensor is used, it makes sense to detect the electrical conductivity, the inductances or other electrical properties of the fluid.
Zweckmäßig ist die Sensoreinrichtung stromauf der Filtereinrichtung im Fluid- kreislauf angeordnet. Somit kann in dem Fluid vor dem Durchströmen der Filter einrichtung detektiert werden, ob Schmutzpartikel vorhanden sind, sodass der Bypass aktiviert werden kann, falls dies nicht zutrifft. Suitably, the sensor device is arranged upstream of the filter device in the fluid circuit. Thus, in the fluid before flowing through the filter device can be detected, if there are dirt particles, so that the bypass can be activated, if not.
Gemäß einer vorteilhaften Weiterbildung ist die Sensoreinrichtung zur Detektion der dielektrischen Eigenschaften, insbesondere der Dielektrizitätszahl, des Fluids ausgebildet. Da sich die dielektrischen Eigenschaften, insbesondere die Dielektri- zitätszahl, des Fluids ändert, falls im Fluid elektrisch leitende Schmutzpartikel vorhanden sind, lässt sich auf diese Weise besonders einfach feststellen, ob das Fluid zum Reinigen von Schmutzpartikel durch die Filtereinrichtung geführt wer- den soll oder nicht. According to an advantageous development, the sensor device is for the detection of the dielectric properties, in particular the dielectric constant, of the fluid educated. Since the dielectric properties, in particular the dielectric constant, of the fluid changes if electrically conductive dirt particles are present in the fluid, it is particularly easy to determine whether the fluid for cleaning dirt particles is to be guided through the filter device or Not.
Gemäß einer anderen bevorzugten Ausführungsform ist die Sensoreinrichtung zur Detektion des Wassergehalts des Fluids ausgebildet. Da Wasser normalerweise elektrisch leitende Eigenschaften besitzt, kann auf diese Weise erkannt werden, wenn aufgrund eines zu hohen Wassergehalts in dem Fluid ein elektrischer Kurz- schluss in dem zu temperierenden Batteriezellenmodul hervorgerufen werden könnte. According to another preferred embodiment, the sensor device is designed to detect the water content of the fluid. Since water normally has electrically conductive properties, it can be detected in this way if, due to an excessively high water content in the fluid, an electrical short-circuit could be caused in the battery cell module to be tempered.
Gemäß einer anderen vorteilhaften Weiterbildung umfasst die Filtereinrichtung einen Wasserabscheider zum Abscheiden des in dem Fluid vorhandenen Was- sers. Ist die Sensoreinrichtung in der Lage, den Wassergehalt des Fluid zu detek- tieren, so kann beim Durchströmen der Filtereinrichtung im Bedarfsfall auch das im Fluid vorhandene Wasser zumindest teilweise, idealerweise sogar vollständig, aus dem Fluid entfernt werden. Auf diese Weise wird verhindert, dass das elektrisch leitende Wasser in analoger Weise zu elektrisch leitenden Schmutzpar- tikel in dem zu temperierenden Batteriezellenmoduls einen elektrischen Kurz- schluss verursachen kann. According to another advantageous development, the filter device comprises a water separator for separating the water present in the fluid. If the sensor device is capable of detecting the water content of the fluid, it is also possible for the water present in the fluid to be at least partially, ideally even completely, removed from the fluid as it flows through the filter device. In this way it is prevented that the electrically conductive water in an analogous manner to electrically conductive dirt particles in the battery cell module to be tempered can cause an electrical short circuit.
Gemäß einer weiteren vorteilhaften Weiterbildung umfasst die Filtereinrichtung einen Partikelfilter zum Separieren der Schmutzpartikel aus dem Fluid. Dies er- laubt es auf effektive Weise, die in dem Fluid vorhandenen Schmutzpartikel zu separieren. Gemäß einer anderen vorteilhaften Weiterbildung ist die Filtereinrichtung in einer Fluidleitung des Filterkreislaufs angeordnet. Bei dieser Weiterbildung umfasst der Filterbypass eine Bypassleitung, die stromauf der Fluidleitung in einem Ab- zweigpunkt von der Fluidleitung abzweigt und stromab der Filtereinrichtung, vor- zugsweise in einem Mündungspunkt, wieder in die Fluidleitung mündet. Die Venti- leinrichtung ist dabei in dem Abzweigpunkt angeordnet. Diese Weiterbildung er- fordert zur Realisierung der Filtereinrichtung und des zusätzlichen Bypasses be- sonders wenig Bauraum. Dabei empfiehlt es sich, in dem Abzweigpunkt, sowie al- ternativ oder zusätzlich, in dem Mündungspunkt ein Dreiwegeventil anzuordnen. Ein solches Dreiwegeventil erfordert besonders wenig Bauraum und erlaubt auf einfache Weise die erforderliche Verstellung der Ventileinrichtung zwischen der Filter-Stellung und der Bypass-Stellung. According to a further advantageous development, the filter device comprises a particle filter for separating the dirt particles from the fluid. This effectively allows separation of the debris present in the fluid. According to another advantageous development, the filter device is arranged in a fluid line of the filter circuit. In this refinement, the filter bypass comprises a bypass line, which branches off from the fluid line upstream of the fluid line at a branch point and opens again into the fluid line downstream of the filter device, preferably at an outlet point. The valve device is arranged in the branch point. This development requires particularly little installation space to realize the filter device and the additional bypass. It is advisable to arrange a three-way valve in the branch point, as well as alternatively or additionally, in the outlet point. Such a three-way valve requires very little space and allows in a simple way the required adjustment of the valve means between the filter position and the bypass position.

The same applies to the opposite case, that is, when heat was transferred from the fluid to this for heating the battery cell module. In this case, the heat required for this purpose can be supplied to the fluid with the aid of the heat exchanger.

Bei einer bevorzugten Ausführungsform des Verfahrens wird der Verschmut- zungsgrad von einer im Fluidkreislauf vorhandenen Sensoreinrichtung detektiert Bei dieser Ausführungsform wird die Ventileinrichtung mittels einer Steuerungs- /Regelungseinrichtung im Abhängigkeit vom detektierten Verschmutzungsgrad zwischen einer Filter-Stellung und einer Bypass-Stellung verstellt. In der Filter- Stellung wird das Fluid vollständig durch die Filtereinrichtung geführt, in der By- pass-Stellung hingegen vollständig an der Filtereinrichtung vorbeigeführt.

Depending on the degree of contamination detected, the valve device is particularly preferably adjusted to an intermediate position, in which the fluid is guided partially in each case through both the filter device and the filter device.
Besonders bevorzugt wird mit zunehmendem detektierten Verschmutzungsgrad durch Verstellung der Ventileinrichtung zur Filter-Stellung hin ein zunehmender Teil des Fluids durch die Filtereinrichtung geführt.

Die einzige Figur 1 zeigt in schematischer Darstellung ein Beispiel einer erfin- dungsgemäßen Temperiereinrichtung 1 zum Temperieren eines Batteriezellen- moduls 21 für ein Kraftfahrzeugs. Die Temperiereinrichtung 1 umfasst einen Flu- idkreislauf 2, in welchem ein Fluid F zum Temperieren des Batteriezellenmoduls 21 zirkuliert. Das in der Figur 1 nur grobschematisch dargestellte und im Fluid- kreislauf 2 angeordnete Batteriezellenmodul 21 kann eine, zwei oder mehr Batte- riezellen 22 aufweisen. Unabhängig von der Anzahl an vorhandenen Batteriezel- len 22 ist das Batteriezellenmodul 21 im Fluidkreislauf 2 angeordnet, so dass es von dem im Fluidkreislauf 2 zirkulierenden Fluid F umströmt/durchströmt wird. Dabei können das Batteriezellenmodul 21 sowie, alternativ oder zusätzlich, die Batteriezellen 22 des Batteriezellenmoduls 21 ein Modul-Gehäuse 23 bzw. ein oder mehrere Batteriezellen-Gehäuse 24 aufweisen, welches von dem im Fluid kreislauf 2 zirkulierenden Fluid F umströmt oder/und durchströmt ist. The sole FIGURE 1 shows a schematic representation of an example of a tempering device 1 according to the invention for tempering a battery cell module 21 for a motor vehicle. The tempering device 1 comprises a fluid idkreislauf 2, in which a fluid F circulates for controlling the temperature of the battery cell module 21. The battery cell module 21, which is only roughly illustrated in FIG. 1 and arranged in the fluid circuit 2, may have one, two or more battery cells 22. Regardless of the number of existing battery cells 22, the battery cell module 21 is arranged in the fluid circuit 2 so that it flows around / flows through the fluid F circulating in the fluid circuit 2. In this case, the battery cell module 21 and, alternatively or additionally, the battery cells 22 of the battery cell module 21, a module housing 23 and a or a plurality of battery cell housing 24 which flows around the fluid circulating in the fluid 2 circulating fluid F and / or flowed through.
Das im Fluidkreislauf 2 zirkulierende Fluid F ist - abgesehen von im Fluid F vor- handenem elektrisch leitenden Wasser und von im Fluid vorhandenen, elektrisch leitenden Verunreinigungen - elektrisch nicht-leitend ausgebildet. Im Flu idkreis- lauf 2 ist eine Fördereinrichtung 3, beispielsweise in Form einer geeigneten För- derpumpe, zum Fördern des Fluids F angeordnet. Ferner ist im Fluidkreislauf 2 eine Filtereinrichtung 4 zum Reinigen des Fluids F angeordnet. Flierzu kann die Filtereinrichtung 4 mit einem Partikelfilter 9 zum Separieren von in dem Fluid F vorhandenen Schmutzpartikeln und anderen Verunreinigungen ausgestattet sein. Weiterhin umfasst die Temperiereinrichtung 1 einen im Fluidkreislauf 2 vorgese- henen Filterbypass 5, welcher an der im Fluidkreislauf 2 angeordneten Filterein- richtung 4 vorbeiführt. Durch den Filterbypass 5 geführtes Fluid F strömt also nicht durch die Filtereinrichtung 4. The fluid F circulating in the fluid circuit 2 is electrically non-conductive, apart from electrically conductive water present in the fluid F and electrically conductive impurities present in the fluid. In Flu idkreis- run 2 is a conveyor 3, for example in the form of a suitable delivery pump, arranged to convey the fluid F. Furthermore, a filter device 4 for cleaning the fluid F is arranged in the fluid circuit 2. The filter device 4 can also be equipped with a particle filter 9 for separating dirt particles present in the fluid F and other contaminants. Furthermore, the tempering device 1 comprises a filter bypass 5 provided in the fluid circuit 2, which bypasses the filter device 4 arranged in the fluid circuit 2. Thus, fluid F passed through the filter bypass 5 does not flow through the filter device 4.
Entsprechend Figur 1 ist die Filtereinrichtung 4 in einer Fluidleitung 1 1 angeord- net, die einen Teil des Fluidkreislaufs 2 bildet. Weiterhin umfasst der Filterbypass 5 eine im Fluidkreislauf 2 angeordnete Bypassleitung 12, die stromauf der Fluid- leitung 11 in einem Abzweigpunkt 13 von der Fluidleitung 11 abzweigt und strom- ab der Filtereinrichtung 4 in einem Mündungspunkt 14 wieder in die Fluidleitung 11 mündet. Die Filtereinrichtung 4 und der Filterbypass 5 sind also in der Art ei- ner„Parallelschaltung“ angeordnet. Ferner umfasst die Temperiereinrichtung 1 eine im Fluidkreislauf 2 angeordnete Ventileinrichtung 6. Mittels der Ventileinrich tung 6 ist einstellbar, ob das Fluid F durch die Filtereinrichtung 4 oder an der Fil- tereinrichtung 4 vorbei durch den Filterbypass 5 geführt wird. H ierfür ist die Ven- tileinrichtung 6, die als 3-Wege-Ventil 15 ausgebildet sein kann, ist in dem Ab- zweigpunkt 13. Außerdem umfasst die Temperiereinrichtung 1 eine Sensoreinrichtung 7, mittels welcher das Vorhandensein von Verunreinigungen in Form von Schmutzpartikeln (nicht dargestellt) bzw. ein Verschmutzungsgrad mit diesen Schmutzpartikeln in dem Fluid F detektiert werden kann. Sowohl mit der Ventileinrichtung 6 als auch mit der Sensoreinrichtung 7 wirkt eine Steuerungs-/Regelungseinrichtung 16 zu- sammen, die derart eingerichtet/programmiert ist, dass sie die Ventileinrichtung 6 in Abhängigkeit von dem detektierten Verschmutzungsgrad verstellt. Die Verstel- lung der Ventileinrichtung 6 erfolgt zwischen einer Filter-Stellung, in welcher das Fluid vollständig durch die Filtereinrichtung 4 - und nicht durch den Filterbypass 5 geführt wird, und einer Bypass-Stellung, in welcher das Fluid F vollständig durch den Filterbypass 5 - und nicht durch die Filtereinrichtung 4 - geführt wird. Dabei kann Ventileinrichtung 6 von der Steuerungs-/Regelungseinrichtung 16 je nach detektieren Verschmutzungsgrad auch in eine Zwischenstellung verstellt werden, in welcher das Fluid F jeweils teilweise durch sowohl durch die Filterein- richtung 4 als auch an der Filtereinrichtung 4 vorbei durch den Filterbypass 5 ge- führt wird. According to FIG. 1, the filter device 4 is arranged in a fluid line 11, which forms part of the fluid circuit 2. Furthermore, the filter bypass 5 comprises a bypass line 12 arranged in the fluid circuit 2, which branches off from the fluid line 11 upstream of the fluid line 11 at a branch point 13 and flows back into the fluid line 11 downstream of the filter device 4 at an outlet point 14. The filter device 4 and the filter bypass 5 are thus arranged in the manner of a "parallel connection". Furthermore, the tempering device 1 comprises a valve device 6 arranged in the fluid circuit 2. By means of the valve device 6 it is possible to set whether the fluid F is guided through the filter bypass 5 past the filter device 4 or past the filter device 4. Here, the valve device 6, which may be designed as a 3-way valve 15, is in the branch point 13. In addition, the tempering device 1 comprises a sensor device 7, by means of which the presence of impurities in the form of dirt particles (not shown) or a degree of contamination with these dirt particles in the fluid F can be detected. A control / regulation device 16, which is set up / programmed in such a way that it adjusts the valve device 6 as a function of the detected degree of soiling, acts together with both the valve device 6 and the sensor device 7. The adjustment of the valve device 6 takes place between a filter position, in which the fluid is passed completely through the filter device 4 - and not through the filter bypass 5, and a bypass position, in which the fluid F completely through the filter bypass 5 -. and not by the filter device 4 - is performed. In this case, valve device 6 can also be adjusted by control / regulating device 16 into an intermediate position, depending on the degree of soiling detected, in which fluid F is in each case partially passed through filter filter 5 both through filter device 4 and filter device 4. leads.
Zweckmäßig wird dabei mit zunehmendem detektierten Verschmutzungsgrad durch entsprechende Verstellung der Ventileinrichtung 6 zur Filter-Stellung hin ein zunehmender Anteil des Fluids F durch die Filtereinrichtung 4 geführt. Alter- nativ oder zusätzlich wird mit abnehmendem detektierten Verschmutzungsgrad durch Verstellung der Ventileinrichtung 6 zur Bypass-Stellung hin ein zunehmen- der Anteil des Fluids F über den Filterbypass 5 an der Filtereinrichtung 4 vorbei geführt. Appropriately, an increasing proportion of the fluid F is guided through the filter device 4 with increasing detected contamination level by corresponding adjustment of the valve device 6 to the filter position. Alternatively or additionally, as the detected degree of soiling decreases due to adjustment of the valve device 6 to the bypass position, an increasing proportion of the fluid F passes via the filter bypass 5 past the filter device 4.
Die Sensoreinrichtung 7 ist stromauf der Filtereinrichtung 4 im Fluidkreislauf 2 angeordnet und kann jeweils einen oder mehrere optische(n), elektrische(n), so- wie akustische(n) Sensor(en) 8 aufweisen, die in Figur 1 nur grobschematisch angedeutet sind. Falls ein elektrischer Sensor 8 vorgesehen ist, so kann dieser besonders bevorzugt zur Detektion der dielektrischen Eigenschaften, insbeson- dere der Dielektrizitätszahl, des Fluid F ausgebildet sein. Außerdem kann die Sensoreinrichtung 7 mit dem Sensor 8 bzw. mit den Sensoren 8 zur Detektion des Wassergehalts des Fluids F ausgebildet sein. Flierzu kann die Filtereinrichtung einen Wasserabscheider 10 zum Abscheiden des in dem Fluid F vorhandenen Wassers aufweisen. The sensor device 7 is arranged upstream of the filter device 4 in the fluid circuit 2 and can each have one or more optical (s), electrical (n), and acoustic (s) sensor (s) 8, which are only roughly sketched in FIG , If an electrical sensor 8 is provided, it may be particularly preferred for the detection of the dielectric properties, in particular the dielectric constant, the fluid F be formed. In addition, the sensor device 7 may be formed with the sensor 8 or with the sensors 8 for detecting the water content of the fluid F. The filter device can also have a water separator 10 for separating the water present in the fluid F.
Der Abzweigpunkt 13 mit der Ventileinrichtung 6 ist gemäß Figur 1 stromauf der Filtereinrichtung 4 und stromab der Sensoreinrichtung 7 im Fluidkreislauf 2 ange- ordnet. Auch im Mündungspunkt 14 kann eine Ventileinrichtung, insbesondere in Form eines Dreiwegeventils angeordnet sein. The branch point 13 with the valve device 6 is arranged according to FIG. 1 upstream of the filter device 4 and downstream of the sensor device 7 in the fluid circuit 2. Also in the mouth point 14 may be arranged a valve device, in particular in the form of a three-way valve.
Ferner kann im Fluidkreislauf 2 ein Wärmetauscher 17 zum Zuführen von Wärme in das Fluid F sowie zum Abführen von Wärme von dem Fluid F angeordnet sein. Der Wärmeübertrager 17 kann wie in Figur 1 angedeutet als Zweistrom- Wärmetauscher ausgebildet sein, der neben dem im Fluidkreislauf 2 zirkulieren- den Fluid F von einem weiteren Fluid F* durchströmt wird, welches im Wärmetau- scher 17 thermisch mit dem Fluid F verbunden wird. Auf diese Weise kann die von dem Batteriezellenmodul 21 erzeugte und von dem Fluid F aufgenommene Abwärme durch Übertragung auf das weitere Fluid F* aus dem Fluidkreislauf 2 und somit aus der Temperiereinrichtung 1 abgeführt werden. Gleiches wird gilt für den umgekehrten Fall, also wenn zum Beheizen des Batteriezellenmoduls 21 Wärme vom Fluid F auf das Batteriezellenmodul 21 übertragen wurde. In diesem Fall kann die hierfür notwendige Wärme dem Fluid F mittels des Wärmeübertra- gers 17 durch Wärmeübertragung vom weiteren Fluid F* auf das Fluid F zugeführt werden. Furthermore, a heat exchanger 17 for supplying heat into the fluid F and for removing heat from the fluid F may be arranged in the fluid circuit 2. As is indicated in FIG. 1, the heat exchanger 17 can be designed as a two-flow heat exchanger, through which a further fluid F * flows in addition to the fluid F circulating in the fluid circuit 2, which is thermally connected to the fluid F in the heat exchanger 17. In this way, the waste heat generated by the battery cell module 21 and absorbed by the fluid F can be removed from the fluid circuit 2 and thus from the tempering device 1 by transfer to the further fluid F *. The same applies to the opposite case, that is, when heat was transferred from the fluid F to the battery cell module 21 for heating the battery cell module 21. In this case, the heat required for this purpose can be supplied to the fluid F by means of the heat exchanger 17 by heat transfer from the further fluid F * to the fluid F.
