Definitions

  • the invention relates to an energy storage unit and a battery system.
  • the energy storage unit and the battery system are particularly suitable for use in a hybrid or electric vehicle.
  • Hybrid-powered vehicles also called hybrid vehicles, have, for example, an internal combustion engine, an electric machine and one or more electrochemical energy stores.
  • Electric vehicles with fuel cells generally consist of a fuel cell for energy conversion, a tank for liquid or gaseous energy carriers, an electrochemical energy storage and an electric machine for the drive.
  • the electric machine of the hybrid vehicle is usually designed as a starter / generator and / or electric drive.
  • a starter / generator it replaces the normally existing starter and alternator.
  • an additional torque i. an acceleration torque to propel the vehicle from the electric machine will be contributed.
  • As a generator it enables a recuperation of braking energy and onboard power supply.
  • hybrid controller In a pure electric vehicle, the drive power is provided solely by an electric machine. Both vehicle types, hybrid and electric vehicles, have in common that large amounts of electrical energy must be provided and transferred. The control of the energy flow takes place via an electronics commonly called hybrid controller. Among other things, it decides whether and in what quantity the energy store should be taken or supplied with energy.
  • the energy extraction from the fuel cell or the energy storage is generally used to represent drive power and to supply the vehicle electrical system.
  • the energy supply is used to charge the energy storage or to convert braking energy into electrical energy, i. regenerative braking.
  • the energy storage for hybrid applications can be recharged while driving.
  • the energy required for this is provided by the internal combustion engine.
  • the energy store has at least one, usually two, energy storage components.
  • Energy storage components i. Components used as energy suppliers and storage for electric vehicle applications are optimized for high power densities.
  • energy storage components for energy storage for hybrid applications can already achieve power densities of 3-4kW / kg and more.

  • the cooling of various components by means of a cooling unit can be problematic if they fulfilled by, for example, various components to be cooled under ⁇ different functions, are composed of different materi- lien and / or have different optimum Be ⁇ operating temperature ranges.
  • the cooling of various components by means of a cooling unit can be problematic, because the cooling effect decreases with increasing components to be cooled, which leads either to a reduced to insufficient cooling capacity or enlargement of the cooling unit.
  • the inventors have found that it is possible to cool the electronic component and the energy storage component by means of a cooling unit and at the same time to realize the energy storage unit in a compact design.
  • a Integrati ⁇ on the electronic component in the cooling system of the energy storage component ⁇ is possible in a compact design, without compromising operational safety.

  • This method of Anord ⁇ voltage of the individual components has an effect especially for energy storage devices and battery systems that consists of an odd number of energy storage components, such that the Bi-Pack comprises an energy storage component and an electronic component that are arranged on two relievelie ⁇ constricting sides of the cooling unit ,
  • the cooling unit is sandwiched between the energy storage component and the electronic component.
  • the sandwich-like arrangement is preferably realized in that the base body of the cooling unit, the energy storage component and the electric ⁇ nikkomponente available through sandwiching possibly via intermediate layers contact each other are formed flat. This means that they have a substantially smaller dimension in a direction perpendicular to a plane than in the other two directions running along the plane.

  • the base body of the cooling unit preferably has at least one cooling channel for dissipating heat through a cooling medium. Further preferably ⁇ least the base body of the cooling unit partially an electrically insulating ebenleitfähi- ges material which at least partially forms an outer surface of the base body preferably.
  • cooling ⁇ unit and the energy storage component or between the cooling unit and the electronic component foils can bei- For example, be arranged for electrical insulation and / or an adhesive, if necessary.
  • the basic body of the cooling unit, the electronic component and the energy storage component are formed flat, ie with a large volume in relation to the surface, which serves a thermal coupling of the body together, heat can be dissipated effectively.
  • the heat sink is strategically positioned on the main body of the electronic component and the body of the Energyspei ⁇ cherkomponente to flush. Through the flush concerns ei ⁇ ne thermal coupling can be realized efficiently and without disturbing air inlet ⁇ connections.

Energiespeichereinheit und Batteriesystem Energy storage unit and battery system
Die Erfindung betrifft eine Energiespeichereinheit und ein Batteriesystem. Die Energiespeichereinheit und das Batteriesystem sind insbesondere zur Verwendung in einem Hybrid- bzw. Elektrofahrzeug geeignet. The invention relates to an energy storage unit and a battery system. The energy storage unit and the battery system are particularly suitable for use in a hybrid or electric vehicle.
Als Hybrid- bzw. Elektrofahrzeug bezeichnet man Fahrzeuge, die prinzipbedingt ganz oder teilweise durch elektrische Energie angetrieben werden. Kraftfahrzeuge mit Hybridantrieb, auch Hybridfahrzeuge genannt, weisen beispielsweise eine Verbrennungsmaschine, eine elektrische Maschine und einen oder mehrere elektrochemische Energiespeicher auf. Elektrofahrzeuge mit Brennstoffzellen bestehen allgemein aus einer Brennstoffzelle zur Energiewandlung, einem Tank für flüssige oder gasförmige Energieträger, einem elektrochemischen Energiespeicher und einer elektrischen Maschine für den Antrieb. As hybrid or electric vehicle refers to vehicles that are inherently driven in whole or in part by electrical energy. Hybrid-powered vehicles, also called hybrid vehicles, have, for example, an internal combustion engine, an electric machine and one or more electrochemical energy stores. Electric vehicles with fuel cells generally consist of a fuel cell for energy conversion, a tank for liquid or gaseous energy carriers, an electrochemical energy storage and an electric machine for the drive.
Die elektrische Maschine des Hybridfahrzeuges ist in der Regel als Starter/Generator und/oder elektrischer Antrieb ausgeführt. Als Starter/Generator ersetzt sie den normalerweise vorhandenen Anlasser und die Lichtmaschine. Bei einer Ausführung als elektrischer Antrieb kann ein zusätzliches Drehmoment d.h. ein Beschleunigungsmoment zum Vortrieb des Fahrzeugs von der elektrischen Maschine beigetragen werden. Als Generator ermöglicht sie eine Rekuperation von Bremsenergie und Bordnetzversorgung. The electric machine of the hybrid vehicle is usually designed as a starter / generator and / or electric drive. As a starter / generator it replaces the normally existing starter and alternator. In an embodiment as an electric drive, an additional torque i. an acceleration torque to propel the vehicle from the electric machine will be contributed. As a generator, it enables a recuperation of braking energy and onboard power supply.
Bei einem reinen Elektrofahrzeug wird die Antriebsleistung allein durch eine elektrische Maschine bereitgestellt. Beiden Fahrzeugtypen, Hybrid- und Elektrofahrzeug, ist gemein, dass große Mengen elektrischer Energie bereitgestellt und transferiert werden müssen. Die Steuerung des Energieflusses erfolgt über eine Elektronik allgemein Hybrid-Controller genannt. Er entscheidet unter anderem, ob und in welcher Menge dem Energiespeicher Energie entnommen oder zugeführt werden soll. In a pure electric vehicle, the drive power is provided solely by an electric machine. Both vehicle types, hybrid and electric vehicles, have in common that large amounts of electrical energy must be provided and transferred. The control of the energy flow takes place via an electronics commonly called hybrid controller. Among other things, it decides whether and in what quantity the energy store should be taken or supplied with energy.
Die Energieentnahme aus der Brennstoffzelle oder dem Energiespeicher dient allgemein zur Darstellung von Antriebsleistung und zur Versorgung des Fahrzeugbordnetzes. Die Energiezuführung dient der Aufladung des Energiespeichers bzw. zur Wandlung von Bremsenergie in elektrische Energie, d.h. dem regenerativen Bremsen. The energy extraction from the fuel cell or the energy storage is generally used to represent drive power and to supply the vehicle electrical system. The energy supply is used to charge the energy storage or to convert braking energy into electrical energy, i. regenerative braking.
Der Energiespeicher für Hybridanwendungen kann während des Fahrbetriebs wieder aufgeladen werden. Die hierfür benötigte Energie stellt der Verbrennungsmotor bereit. The energy storage for hybrid applications can be recharged while driving. The energy required for this is provided by the internal combustion engine.
Der Energiespeicher weist mindestens eine, meist zwei, Energiespeicherkomponenten auf. Energiespeicherkomponenten, d.h. Komponenten, die als Energielieferanten und Speicher für Elektrofahrzeuganwendungen eingesetzt werden, sind dabei auf hohe Leistungsdichten optimiert. Energiespeicherkomponenten für Energiespeicher für Hybridanwendungen können beispielsweise bereits Leistungsdichten von 3-4kW/kg und mehr erreichen . The energy store has at least one, usually two, energy storage components. Energy storage components, i. Components used as energy suppliers and storage for electric vehicle applications are optimized for high power densities. For example, energy storage components for energy storage for hybrid applications can already achieve power densities of 3-4kW / kg and more.
Bei derart hohen Leistungsdichten sind Sicherungsmaßnahmen zwingend erforderlich. Bauelemente sind hierbei beispielswei¬ se Elektronikkomponenten wie Schalter und Schmelzsicherungen. Bei einer hohen Belastung wie Stromdurchsatz erwärmt sich die Elektronikkomponente relativ stark, sodass eine entsprechende Kühlung bei hohen Strömen notwendig ist. Die Kühlung von Elektronikkomponenten ist generell hinreichend bekannt. Je¬ doch ist es manchmal notwendig, dass das Kühlsystem möglichst kompakt aufgebaut wird und möglichst gut in ein Batteriesys- tem integriert wird. Aufgabe der Erfindung ist daher, eine Batterie für ein Hyb¬ rid- oder Elektrofahrzeug zur Verfügung zu stellen, die mög¬ lichst kompakt aufgebaut ist und sicher betrieben werden kann . With such high power densities, safety measures are mandatory. Components here are beispielswei ¬ se electronic components such as switches and fuses. At a high load such as current throughput, the electronic component heats relatively high, so that a corresponding cooling at high currents is necessary. The cooling of electronic components is generally well known. Depending ¬ but it is sometimes necessary that the cooling system is as compact as possible and as well as possible integrated into a Batteriesys- tem. The object of the invention is therefore to provide a battery for a Hyb ¬ rid- or electric vehicle available, which is pos ¬ lichst compact and can be operated safely.
Erfindungsgemäß wird die Aufgabe durch eine Energiespeicher¬ einheit mit den Merkmalen von Anspruch 1 und ein Batteriesystem mit den Merkmalen von Anspruch 10 gelöst. Die Energiespeichereinheit weist eine Energiespeicherkompo¬ nente, eine Elektronikkomponente und eine Kühleinheit auf, wobei die Kühleinheit ausgebildet ist, die Energiespeicher¬ komponente und die Elektronikkomponente zu kühlen. Die Ener¬ giespeichereinheit liefert Energie, und die Elektronikkompo- nente stellt sicher, dass die Energiespeichereinheit sicher und effektiv betrieben wird. Der Grundgedanke der Erfindung ist, durch eine Integration der Elektronikkomponente in die Energiespeicherkomponentenkühlung die Aufgabe vorteilhaft zu lösen. D.h. die Energiespeicherkomponente wird in idealer Weise an der gleichen Kühleinheit betrieben wie die Elektro¬ nikkomponente. Die Kühlung verschiedener Komponenten mittels einer Kühleinheit kann problematisch sein, wenn durch sie beispielsweise verschiedene zu kühlende Komponenten unter¬ schiedliche Funktionen erfüllen, aus verschiedenen Materia- lien aufgebaut sind und/oder unterschiedliche optimale Be¬ triebstemperaturbereiche aufweisen. Zum anderen kann die Kühlung verschiedener Komponenten mittels einer Kühleinheit problematisch sein, weil sich die Kühlwirkung mit Erhöhung von zu kühlenden Komponenten verringert, was entweder zu ei- ner verringerten bis zu nicht ausreichenden Kühlleistung oder Vergrößerung der Kühleinheit führt. Überraschend haben die Erfinder herausgefunden, dass es möglich ist, die Elektronikkomponente und die Energiespeicherkomponente mittels einer Kühleinheit zu kühlen und gleichzeitig die Energiespeicher- einheit in kompakter Bauweise zu realisieren. Eine Integrati¬ on der Elektronikkomponente in das Kühlsystem der Energie¬ speicherkomponente ist daher in kompakter Bauweise möglich, ohne dass die Betriebssicherheit gefährdet wird. Die Kühlein¬ heit kann ein Kühler/Kühlkörper oder ein Kühlkreislauf sein. According to the invention the object is achieved by an energy storage ¬ unit with the features of claim 1 and a battery system with the features of claim 10. The energy storage unit comprises a Energiespeicherkompo ¬ component, an electronic component and a cooling unit, said cooling unit is formed, the energy storage component ¬ and to cool the electronic component. The Ener ¬ giespeichereinheit provides energy and Elektronikkompo- component ensures that the energy storage unit is operated safely and effectively. The basic idea of the invention is to solve the problem advantageously by integrating the electronic component in the energy storage component cooling. Ie the energy storage component is operated ideally on the same cooling unit as the electric ¬ nikkomponente. The cooling of various components by means of a cooling unit can be problematic if they fulfilled by, for example, various components to be cooled under ¬ different functions, are composed of different materi- lien and / or have different optimum Be ¬ operating temperature ranges. On the other hand, the cooling of various components by means of a cooling unit can be problematic, because the cooling effect decreases with increasing components to be cooled, which leads either to a reduced to insufficient cooling capacity or enlargement of the cooling unit. Surprisingly, the inventors have found that it is possible to cool the electronic component and the energy storage component by means of a cooling unit and at the same time to realize the energy storage unit in a compact design. A Integrati ¬ on the electronic component in the cooling system of the energy storage component ¬ is possible in a compact design, without compromising operational safety. The Kühlein ¬ ness can be a cooler / heat sink or a cooling circuit.
Idealerweise ist die Elektronikkomponente an der gleichen Kühleinheit befestigt wie die Energiespeicherkomponente, so¬ dass beide einen sogenannten Bi-Pack bilden, wobei die Energiespeicherkomponente auf der einen Seite der Kühleinheit und die Elektronikkomponente auf der Seite der Kühleinheit ange¬ ordnet ist, die der Seite mit der daran angeordneten Energie- Speicherkomponente gegenüberliegt. Diese Methode zur Anord¬ nung der einzelnen Komponenten wirkt sich insbesondere bei Energiespeichereinheiten und Batteriesystemen aus, die aus einer ungeraden Anzahl der Energiespeicherkomponenten besteht, sodass das Bi-Pack eine Energiespeicherkomponente und eine Elektronikkomponente umfasst, die auf zwei gegenüberlie¬ genden Seiten der Kühleinheit angeordnet sind. Ideally, the electronic component mounted on the same cooling unit as the energy storage component, so ¬ that both form a so-called bi-pack, wherein the energy storage component on one side of the cooling unit and the electronic component is attached ¬ arranged on the side of the cooling unit to the side with the energy storage component disposed opposite thereto. This method of Anord ¬ voltage of the individual components has an effect especially for energy storage devices and battery systems that consists of an odd number of energy storage components, such that the Bi-Pack comprises an energy storage component and an electronic component that are arranged on two gegenüberlie ¬ constricting sides of the cooling unit ,
In einer vorteilhaften Ausführungsform ist die Kühleinheit sandwichartig zwischen der Energiespeicherkomponente und der Elektronikkomponente angeordnet. Die sandwichartige Anordnung ist vorzugsweise dadurch realisiert, dass Grundkörper der Kühleinheit, der Energiespeicherkomponente und der Elektro¬ nikkomponente, die durch die sandwichartige Anordnung ggf. über Zwischenschichten miteinander in Kontakt stehen, flächig ausgebildet sind. Damit ist gemeint, dass sie in einer senk¬ recht zu einer Ebene verlaufenden Richtung eine wesentlich kleinere Dimension aufweisen, als in den beiden anderen entlang der Ebene verlaufenden Richtungen. Die flächigen Grundkörper dienen zum thermischen Koppeln miteinander. Der Grund- körper der Kühleinheit weist vorzugsweise mindestens einen Kühlkanal zum Abführen von Wärme durch ein Kühlmedium auf. Weiterhin weist der Grundkörper der Kühleinheit bevorzugt zu¬ mindest teilweise ein elektrisch isolierendes wärmeleitfähi- ges Material auf, das vorzugsweise zumindest teilweise eine äußere Oberfläche des Grundkörpers bildet. Zwischen der Kühl¬ einheit und der Energiespeicherkomponente bzw. zwischen der Kühleinheit und der Elektronikkomponente können Folien bei- spielsweise zur elektrischen Isolierung und/oder ein Klebstoff angeordnet sein, wenn erforderlich. Dadurch, dass die Grundkörper der Kühleinheit, der Elektronikkomponente und der Energiespeicherkomponente flächig ausgebildet sind d.h. mit einer im Verhältnis zum Volumen großen Oberfläche, die einer thermischen Kopplung der Grundkörper miteinander dient, kann Wärme effektiv abgeführt werden. In an advantageous embodiment, the cooling unit is sandwiched between the energy storage component and the electronic component. The sandwich-like arrangement is preferably realized in that the base body of the cooling unit, the energy storage component and the electric ¬ nikkomponente available through sandwiching possibly via intermediate layers contact each other are formed flat. This means that they have a substantially smaller dimension in a direction perpendicular to a plane than in the other two directions running along the plane. The flat body serve for thermal coupling with each other. The base body of the cooling unit preferably has at least one cooling channel for dissipating heat through a cooling medium. Further preferably ¬ least the base body of the cooling unit partially an electrically insulating wärmeleitfähi- ges material which at least partially forms an outer surface of the base body preferably. Between the cooling ¬ unit and the energy storage component or between the cooling unit and the electronic component foils can bei- For example, be arranged for electrical insulation and / or an adhesive, if necessary. Characterized in that the basic body of the cooling unit, the electronic component and the energy storage component are formed flat, ie with a large volume in relation to the surface, which serves a thermal coupling of the body together, heat can be dissipated effectively.
Der Kühlkörper liegt vorteilhaft an dem Grundkörper der Elektronikkomponente und an dem Grundkörper der Energiespei¬ cherkomponente bündig an. Durch das bündige Anliegen kann ei¬ ne thermische Kopplung effizient und ohne störende Luftein¬ schlüsse realisiert werden. Der Grundkörper der Kühleinheit weist vorzugsweise eine äuße¬ re Oberfläche, die entsprechend einer Form der Elektronikkom¬ ponente geformt ist, und eine der vorstehenden äußeren Oberfläche gegenüberliegende Oberfläche auf, die entsprechend ei¬ ner Form der Energiespeicherkomponente geformt ist. In einer bevorzugten Ausführungsform sind die beiden vorstehenden Oberflächen der Kühleinheit als ebene Fläche ausgebildet und die die beiden vorstehenden äußeren Oberflächen kontaktierenden Bereiche der Elektronikkomponente und der Energiespei¬ cherkomponente sind ebenfalls als ebene Fläche ausgebildet. Die äußeren Oberflächen der Kühleinheit sind somit zumindest abschnittsweise vorzugsweise vollflächig an die sie kontak¬ tierenden Oberflächen der Elektronikkomponente und der Energiespeicherkomponente angepasst. Die Grundkörper der Elektro¬ nikkomponente und der Energiespeicherkomponente sind vorzugs- weise parallel zueinander angeordnet, sodass eine kompakte Bauweise realisierbar ist. The heat sink is strategically positioned on the main body of the electronic component and the body of the Energiespei ¬ cherkomponente to flush. Through the flush concerns ei ¬ ne thermal coupling can be realized efficiently and without disturbing air inlet ¬ connections. The main body of the cooling unit preferably includes a äuße ¬ re surface that is shaped corresponding to a shape of the Elektronikkom ¬ component, and one of the above outer surface opposite to the surface on which corresponding ei ¬ ner form of the energy storage component is formed. In a preferred embodiment, the two projecting surfaces of the cooling unit are formed as a flat surface and the two outer surfaces contacting the two outer surfaces of the electronic component and the Energiespei ¬ cherkomponente are also formed as a flat surface. The outer surfaces of the cooling unit are thus at least partially, preferably over the entire surface adapted to the kontak ¬ tierenden surfaces of the electronic component and the energy storage component. The basic body of the electronic component ¬ nikkomponente and the energy storage component are preferably arranged parallel to each other, so that a compact design can be realized.
Insbesondere wenn die Kühleinheit aus einem elektrisch iso¬ lierenden Material gefertigt ist, wird durch die sandwichar- tige Anordnung mittels der flächigen Grundkörper der Kühleinheit, der Elektronikkomponente und der Energiespeicherkompo¬ nente ein kompakter Aufbau der Energiespeichereinheit er- reicht, der sowohl die Sicherheitsanforderungen an die Elektronik, elektrische Isolierung als auch an die Wärmeabfuhr erfüllt. Vorzugsweise weisen die Energiespeicherkomponente und die Elektronikkomponente im Wesentlichen eine gleiche Länge und Breite auf. Die Länge und Breite stellen Abmessungen dar, die im Wesentlichen senkrecht zur sandwichartigen Anordnung aus Energiespeicherkomponente, Elektronikkomponente und Kühlein- heit sind. Vorzugsweise weisen der Grundkörper der Energie¬ speicherkomponente und der Grundkörper der Elektronikkompo¬ nente im Wesentlichen die gleiche Länge und Breite auf. Bei¬ spielsweise weisen der Grundkörper der Energiespeicherkompo¬ nente bzw. der Grundkörper der Elektronikkomponente eine Län- ge im Bereich von 150 bis 200 mm, bevorzugt 170 bis 190 mm, und eine Breite im Bereich von 6 bis 10 mm, bevorzugt 8 bis 9 mm, auf. In particular, when the cooling unit is made of an electrically iso ¬ lierenden material, a compact construction of the energy storage unit is represented by the sandwichar- term arrangement means of the tubular main body of the cooling unit of the electronic component and the component Energiespeicherkompo ¬ ER- ranges, which meets both the safety requirements of the electronics, electrical insulation and heat dissipation. Preferably, the energy storage component and the electronic component have substantially the same length and width. The length and width represent dimensions that are substantially perpendicular to the sandwiched arrangement of energy storage component, electronic component and cooling unit. Preferably, the main body of the energy storage component ¬ and the base body of the Elektronikkompo ¬ component have substantially the same length and width.
