Description
Stand der TechnikState of the art
Die Erfindung geht aus von einem Batteriesystem nach Gattung des unabhängigen Anspruchs. Gegenstand der Erfindung ist auch ein Fahrzeug.The invention relates to a battery system according to the preamble of the independent claim. The subject of the invention is also a vehicle.
Sowohl bei stationären Anwendungen, zum Beispiel bei Windkraftanlagen, als auch bei mobilen Anwendungen, zum Beispiel bei Elektrokraftfahrzeugen (electric vehicles, EV), Hybridfahrzeugen (hybrid electric vehicles, HEV) oder Steckdosenhybridfahrzeugen (plug-in hybrid electric vehicles, PHEV), kommen als wieder aufladbare elektrische Energiespeicher (EES, electro-chemical storage system, ESS) vermehrt neue Batteriesysteme (Akkumulatorsystem) bzw. Batteriemodule (Akkumulatormodule, Module), zum Beispiel mit Lithium-Ionen-Zellen (Lithium-Ionen-Akkumulatoren), zum Einsatz.Both in stationary applications, for example in wind turbines, as well as in mobile applications, for example in electric vehicles (EV), hybrid electric vehicles (HEV) or plug-in hybrid electric vehicles (PHEV) come as Rechargeable electric energy storage (EES, electro-chemical storage system, ESS) increasingly new battery systems (accumulator) or battery modules (accumulator modules, modules), for example, with lithium-ion cells (lithium-ion batteries), are used.
Üblicherweise weisen Hochleistungsbatteriesysteme, wie zum Beispiel in Kraftfahrzeugen, insbesondere in Kraftfahrzeugen mit einem Hybridantrieb, Elektroantrieb oder Brennstoffzellenfahrzeugen Module auf, in denen einzelne Batteriezellen über Reihen- und / oder Parallelschaltung zur gewünschten Gesamtenergie elektrisch verbunden werden. Die Module werden im Pack mechanisch fixiert, häufig werden sie dabei verschraubt.Conventionally, high-performance battery systems, such as in motor vehicles, especially in motor vehicles with a hybrid drive, electric drive or fuel cell vehicles have modules in which individual battery cells are electrically connected via series and / or parallel to the desired total energy. The modules are mechanically fixed in the pack, often they are screwed.
Um für eine ausreichende Kühlung der Batteriesysteme zu sorgen, müssen diese gekühlt werden, um die entstehende Verlustwärme abzuführen. Üblicherweise wird hierzu eine Kühlvorrichtung eingesetzt, die mit den Batteriezellen thermisch verbunden ist. Die Kühlung erfolgt dann dadurch, dass die Module je Packebene auf eine oder mehrere Kühlplatten gefügt werden. Dabei werden die Kühlplatten meist über Schläuche hydraulisch verbunden.In order to ensure sufficient cooling of the battery systems, they must be cooled in order to dissipate the resulting heat loss. Usually, a cooling device is used for this purpose, which is thermally connected to the battery cells. The cooling then takes place in that the modules are joined per pack level to one or more cooling plates. The cooling plates are usually hydraulically connected via hoses.
Die
Die
Diese im Stand der Technik vorzufindenden Batteriesysteme weisen allerdings Nachteile auf. So ist eine Vielzahl von Mechanikbauteilen erforderlich, um die Bestandteile entsprechend zu befestigen. Der Kostenaufwand wird noch zusätzlich durch die Tatsache gesteigert, dass eine zuverlässige Einzelisolation jeder einzelnen Zelle erforderlich ist.However, these battery systems found in the prior art have disadvantages. Thus, a variety of mechanical components is required to secure the components accordingly. The cost is further increased by the fact that a reliable isolation of each individual cell is required.
Hiervon ausgehend ist es Aufgabe der vorliegenden Erfindung, ein Batteriesystem zur Verfügung zu stellen, das die im Stand der Technik vorzufindenden Nachteile überwindet und einfacher und kostengünstiger zu montieren ist.On this basis, it is an object of the present invention to provide a battery system that overcomes the disadvantages found in the prior art and is easier and less expensive to assemble.
Offenbarung der ErfindungDisclosure of the invention
Das erfindungsgemäße Batteriesystem mit den Merkmalen des unabhängigen Anspruchs 1 hat den Vorteil, dass die Wärme des unteren und oberen Moduls über die gemeinsame Wärmeplatte abführbar ist.The battery system according to the invention with the features of independent claim 1 has the advantage that the heat of the lower and upper module on the common heat plate can be discharged.
Dadurch wird gegenüber dem Stand der Technik eine erhebliche Verbesserung erreicht.As a result, a significant improvement over the prior art is achieved.
Die Wärmeabfuhr aus den Batteriezellen erfolgt über eine Terminalseite der Zelle. Die Terminalseite kann in einer Höhenrichtung der Zelle bei bestimmungsgemäßem Gebrauch oben angeordnet sein. Dabei wird die Wärme der oberen Zellreihe und der unteren Zellreihe über dieselbe Kühlplatte abgeführt. Wahlweise sind die Zellen in das obere und untere Gehäuseteil einfügbar. Dies stellt sicher, dass sowohl die elektrische Kontaktierung wie auch die thermische Kontaktierung der Zellen über eine einzige Seite, die Terminalseite der Zelle, erfolgen. Dies hat den Vorzug, dass die Zellen auf einfache Weise in eine geschlossene Kammer der Gehäuseschalen eingefügt werden können und darüber hinaus keine weiteren Schnittstellen berücksichtigt werden müssen.The heat dissipation from the battery cells via a terminal side of the cell. The terminal side may be arranged at the top in a height direction of the cell when used as intended. The heat of the upper cell row and the lower cell row is dissipated via the same cooling plate. Optionally, the cells can be inserted into the upper and lower housing part. This ensures that both the electrical contacting and the thermal contacting of the cells take place via a single side, the terminal side of the cell. This has the advantage that the cells can be easily inserted into a closed chamber of the housing shells and, moreover, no further interfaces have to be considered.
Die vorliegende Erfindung zeichnet sich gegenüber dem Stand der Technik dadurch aus, dass nur eine zentrale Kühleinheit erforderlich ist. Dadurch entfallen Verschlauchung und packinterne, dichtheitsrelevante (dichtigkeitsrelevante) Verbindungsstellen. Dies führt zu einer Kostenersparnis, da weniger Teile erforderlich sind.The present invention distinguishes itself from the prior art in that only one central cooling unit is required. This eliminates the need for tubing and in-pack, leak-tight (density-relevant) joints. This leads to a cost savings, since fewer parts are required.
Zusätzlich weist die vorliegende Erfindung den Vorteil auf, dass Mechanikbauteile zum Niederhalten der Zelle entfallen, da die Niederhaltekraft durch die Gehäuseschalen bereits aufgebracht wird.In addition, the present invention has the advantage that mechanical components for holding down the cell omitted, since the hold-down force is already applied by the housing shells.
Insgesamt bewirkt die vorliegende Erfindung eine erhebliche Reduzierung der Fertigungskosten durch den Entfall von Bauteilehandling und Montageschritten.Overall, the present invention causes a significant reduction in manufacturing costs due to the elimination of component handling and assembly steps.
Durch den ebenfalls reduzierten Logistikaufwand wird eine weitere Kostenersparnis erzielt. The reduced logistics costs also result in further cost savings.
Schließlich ermöglicht die vorliegende Erfindung eine Einsparung an Bauraum und Gewicht.Finally, the present invention allows a saving of space and weight.
Auch weist das Batteriesystem der vorliegenden Erfindung den Vorteil einer einfachen Demontage zur Reparatur bzw. Erneuerung der Zellen auf. So sind beide Zellebenen nach dem Öffnen des Moduls und der Entnahme der Kühleinheit zugänglich, da beide Zellebenen mit der gleichen Kühleinheit verbunden sind.Also, the battery system of the present invention has the advantage of easy disassembly for repairing or renewing the cells. Thus, both cell levels are accessible after opening the module and removing the cooling unit, since both cell levels are connected to the same cooling unit.
Eine verbesserte Sicherheit wird dadurch erreicht, dass keine Gefahr von Kühlwassereintritt in das Modul vorliegt, da keine Verbindungsstellen innerhalb des Moduls vorhanden sind.An improved safety is achieved in that there is no risk of cooling water entering the module, since there are no connection points within the module.
Vorteilhafte Aus- und Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.Advantageous embodiments and further developments of the invention are the subject of the dependent claims.
In einer bevorzugten Ausführungsform sind die Einzelzellen direkt in ein Gehäuseteil einfügbar. Dies bewirkt eine deutliche Verringerung der Montagekosten. In Abhängigkeit von der Auslegung der Gehäuseschalen besteht zusätzlich die Möglichkeit, dass die Schalen direkt beim Zellhersteller bestückt werden können. Dadurch können Verpackungsmaterial und Handlingsarbeitsgänge in der Packmontage entfallen, was eine zusätzliche Einsparung von Kosten bewirkt. So kann beispielsweise das Packgehäuse aus zwei Halbschalen bestehen.In a preferred embodiment, the individual cells can be inserted directly into a housing part. This causes a significant reduction in assembly costs. Depending on the design of the housing shells, it is additionally possible that the shells can be fitted directly to the cell manufacturer. As a result, packaging material and handling operations in the packaging assembly can be omitted, resulting in an additional cost savings. For example, the pack housing may consist of two half shells.
Vorzugsweise werden die Zellen in zwei Zellebenen montiert. Dabei sind die Zellen direkt in die Gehäuseteile montiert. Es hat sich auch als vorteilhaft erwiesen, wenn Packs mit Modulen hergestellt werden. Dabei müssen aber die Zellen der Module im Terminalbereich an der Kühleinheit thermisch angebunden werden können.Preferably, the cells are mounted in two cell levels. The cells are mounted directly in the housing parts. It has also proved advantageous when making packs with modules. However, the cells of the modules in the terminal area must be able to be thermally connected to the cooling unit.
In einer weiteren bevorzugten Ausführungsform ist das obere Modul kopfüber montierbar, d. h. die Terminalseiten der Zellen können in der Höhenrichtung der Zellen bei bestimmungsgemäßem Gebrauch unten angeordnet sein, bzw. beide Zellreihen sind waagerecht montierbar, d. h. die Terminalseiten der Zellen auf den beiden Zellreihen sind einander zugewandt bzw. die Zellen auf den beiden Zellreihen sind zueinander symmetrisch bzw. spiegelbildlich angeordnet. Dies stellt sicher, dass das obere Modul sowie das untere Modul durch die gleiche Kühlplatte gekühlt werden.In a further preferred embodiment, the upper module is mounted upside down, d. H. the terminal sides of the cells can be arranged below in the height direction of the cells when used as intended, or both cell rows are horizontally mountable, d. H. the terminal sides of the cells on the two rows of cells are facing each other or the cells on the two rows of cells are symmetrical to each other or arranged in mirror image. This ensures that the upper module and the lower module are cooled by the same cooling plate.
In einer weiteren bevorzugten Ausführungsform besteht das Gehäuseteil aus elektrisch nichtleitendem Material. Sind die Gehäuseteile elektrisch isolierend, stellen sie sicher, dass die Einzelzellen des Moduls voneinander elektrisch isoliert sind. Dies bewirkt eine technisch einfache und somit günstige sowie zugleich sichere Isolation der Einzelzellen voneinander.In a further preferred embodiment, the housing part made of electrically non-conductive material. If the housing parts are electrically insulating, they ensure that the individual cells of the module are electrically insulated from one another. This causes a technically simple and thus favorable and at the same time secure isolation of the individual cells from each other.
Dabei hat es sich als vorteilhaft erwiesen, wenn das isolierende Material Polyethylene (PE) oder High-density Polyethylene (HDPE, PE-HD) ist. Dies ermöglicht eine zuverlässige und kostengünstige Isolierung.It has proven to be advantageous if the insulating material is polyethylene (PE) or high-density polyethylene (HDPE, PE-HD). This allows a reliable and cost-effective insulation.
Eine Kostensenkung wird dadurch erreicht, dass eine deutliche Reduzierung von Isolationsprüfungen eintritt, da die Zellen in den Gehäuseschalen bereits isoliert sind, und keine Verbindung zur Masse möglich ist. Dadurch entfällt die Einzelisolation jeder einzelnen Zelle. Stattdessen wird diese Funktion direkt von der Gehäuseschale übernommen. Dies führt zu einer verbesserten Sicherheit und Zuverlässigkeit, da die vollständige elektrische Isolation nicht von Einzelteilen abhängig ist. Darüber hinaus kann der Zulauf und / oder Rücklauf der Kühleinheit direkt als Schnittstelle ausgelegt werden. Dies hat zur Folge, dass die Erdungsanschlüsse entfallen. Demgegenüber muss im Stand der Technik eine zuverlässige Isolation der Einzelzellen aus Sicherheitsgründen jeweils überprüft werden.A reduction in costs is achieved by a significant reduction in insulation tests, since the cells in the housing shells are already insulated, and no connection to the ground is possible. This eliminates the individual isolation of each cell. Instead, this function is taken over directly from the housing shell. This results in improved safety and reliability, as complete electrical isolation is not dependent on parts. In addition, the inlet and / or return of the cooling unit can be designed directly as an interface. This has the consequence that the grounding connections are omitted. In contrast, in the prior art a reliable isolation of the individual cells has to be checked for safety reasons.
In einer weiteren bevorzugten Ausführungsform ist das Batteriesystem das Batteriesystem einer Fahrzeugbatterie, insbesondere einer Batterie für Fahrzeuge mit Elektromotor oder Hybridantrieb oder Brennstoffzellenfahrzeuge.In a further preferred embodiment, the battery system is the battery system of a vehicle battery, in particular a battery for vehicles with electric motor or hybrid drive or fuel cell vehicles.
Die Erfindung stellt weiterhin ein Fahrzeug, insbesondere Kraftfahrzeug wie Elektrokraftfahrzeug, Hybridfahrzeug, Plug-In Hybridfahrzeug oder Elektromotorrad (Elektro-Bike, E-Bike), Elektrofahrrad (Pedal Electric Cycle, Pedelec), ein Seefahrzeug wie Elektroboot oder Unterseeboot (U-Boot), ein Luftfahrzeug oder ein Raumfahrzeug, bereit, das das zuvor beschriebene und mit dem Fahrzeug verbundene Batteriesystem umfasst.The invention further provides a vehicle, in particular motor vehicle such as electric motor vehicle, hybrid vehicle, plug-in hybrid vehicle or electric motorcycle (electric bike, e-bike), electric bicycle (Pedal Electric Cycle, Pedelec), a maritime vehicle such as electric boat or submarine (submarine) , an aircraft, or a spacecraft that includes the battery system previously described and connected to the vehicle.
