Description
Die Erfindung betrifft eine Kühlvorrichtung für eine Fahrzeugbatterie, insbesondere für den Fahrzeugantrieb, mit mehreren Batteriezellengruppen sowie eine Fahrzeugbatteriebaugruppe.The invention relates to a cooling device for a vehicle battery, in particular for the vehicle drive, with a plurality of battery cell groups and a vehicle battery assembly.
Fahrzeuge mit Elektromotorantrieb benötigen große Batterien, um eine ausreichend hohe Reichweite des Fahrzeugs zu ermöglichen, die viel Bauraum im Fahrzeug einnehmen. Derartige Batterien für reine Elektrofahrzeuge oder Hybridfahrzeuge sind üblicherweise mit einer gemeinsamen Kühlvorrichtung ausgestattet, die eine Überhitzung der Batterie beim Laden oder Entladen verhindert.Vehicles with electric motor drive need large batteries to allow a sufficiently high range of the vehicle, taking a lot of space in the vehicle. Such batteries for pure electric vehicles or hybrid vehicles are usually equipped with a common cooling device that prevents overheating of the battery when charging or discharging.
Aufgabe der Erfindung ist es, einen platzsparenden Einbau einer Fahrzeugbatterie in einem Fahrzeug zu ermöglichen.The object of the invention is to enable a space-saving installation of a vehicle battery in a vehicle.
Diese Aufgabe wird durch eine Kühlvorrichtung mit den Merkmalen von Anspruch 1 sowie eine Fahrzeugbatteriebaugruppe mit den Merkmalen von Anspruch 9 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen definiert.This object is achieved by a cooling device having the features of claim 1 and a vehicle battery assembly having the features of claim 9. Advantageous developments of the invention are defined in the dependent claims.
Eine erfindungsgemäße Kühlvorrichtung für eine Fahrzeugbatterie mit mehreren Batteriezellengruppen weist mehrere zu einem Kühlmittelkreislauf gekoppelte Kühlmodule auf. Jedes Kühlmodul ist einer einzige Batteriezellengruppe zugeordnet ist, und jedem Kühlmodul sind eine eigene Kühlmittelzuleitung und eine eigene Kühlmittelrückleitung zugeordnet, wobei die Kühlmittelzuleitungen von einem Kühlmittelzulauf und einem diesem nachgeschalteten Verteiler ausgehen, sodass die Kühlmodule unabhängig und entfernt von einander im Fahrzeug positioniert werden können. Auf diese Weise kann die Fahrzeugbatterie flexibel in das Fahrzeug eingebaut werden, wobei der verfügbare Bauraum im Fahrzeug aufgrund der kleineren unabhängig und entfernt voneinander positionierbaren Batteriezellengruppen mit ihren Kühlmodulen optimal genutzt werden kann. Insbesondere hat jede Batteriezellengruppe ein eigenes Außengehäuse, um eine Einheit zu bilden.A cooling device according to the invention for a vehicle battery having a plurality of battery cell groups has a plurality of cooling modules coupled to a coolant circuit. Each cooling module is assigned to a single battery cell group, and each cooling module is assigned its own coolant supply and own coolant return line, the coolant supply lines starting from a coolant inlet and a downstream distributor, so that the cooling modules can be positioned independently and remotely in the vehicle. In this way, the vehicle battery can be flexibly installed in the vehicle, wherein the available space in the vehicle due to the smaller independently and remotely positionable battery cell groups can be optimally used with their cooling modules. In particular, each battery cell group has its own outer housing to form a unit.
Vorzugsweise umfasst ein Verteilersystem einen Kühlmittelverteiler, einen Kühlmittelsammler und mehrere Kühlmittelzuleitungen und Kühlmittelrückleitungen, wobei die Kühlvorrichtung einen gemeinsamen Kühlmittelzulauf und einen gemeinsamen Kühlmittelablauf für den Kühlmittelkreislauf aufweist. Dies ermöglicht einen einfachen Anschluss des Verteilersystems an ein bestehendes Kühlmittelsystem eines Fahrzeugs.Preferably, a distribution system comprises a coolant distributor, a coolant collector and a plurality of coolant supply lines and coolant return lines, wherein the cooling device has a common coolant inlet and a common coolant outlet for the coolant circuit. This allows easy connection of the distribution system to an existing coolant system of a vehicle.
Um eine einfache Montage der Kühlmodule und Batteriezellengruppen im Fahrzeug und deren Anschluss an den Kühlmittelkreislauf zu ermöglichen, weist ein Kühlmodul einen Zuleitungsanschluss für die Kühlmittelzuleitung und einen Rückleitungsanschluss für die Kühlmittelrückleitung auf.In order to enable a simple assembly of the cooling modules and battery cell groups in the vehicle and their connection to the coolant circuit, a cooling module has a supply connection for the coolant supply line and a return connection for the coolant return line.
Vorzugsweise sind Zuleitungsanschluss und Rückleitungsanschluss an der gleichen Seite des Kühlmoduls angeordnet. Dies ermöglicht es, sowohl die Kühlmittelzuleitung als auch die Kühlmittelrückleitung von der gleichen Seite an das Kühlmodul anzuschließen, es muss also für den Anschluss des Kühlmoduls nur eine Seite zugänglich sein.Preferably, supply port and return port are arranged on the same side of the cooling module. This makes it possible to connect both the coolant supply line and the coolant return line from the same side to the cooling module, so it must be accessible for the connection of the cooling module only one side.
Um eine kostengünstige Produktion zu ermöglichen, sind alle Kühlmodule gleich ausgebildet.In order to enable low-cost production, all cooling modules are the same.
Für eine einfache Montage der Kühlmodule an den Batteriezellengruppen, können die Kühlmodule als Kühlböden zur Kühlung jeweils einer Flachseite der Batteriezellengruppen ausgebildet sein, wobei die Fläche des Kühlbodens vorzugsweise der Fläche der Flachseite der Batteriezellengruppe entspricht.For a simple mounting of the cooling modules to the battery cell groups, the cooling modules may be formed as cooling trays for cooling a respective flat side of the battery cell groups, wherein the surface of the cooling bottom preferably corresponds to the surface of the flat side of the battery cell group.
Gemäß einer bevorzugten Ausführungsform weisen die Kühlmodule jeweils zumindest ein mit Kühlmittel durchströmtes Kühlelement zur wärmeleitenden Kontaktierung ihrer Batteriezellengruppe auf.According to a preferred embodiment, the cooling modules each have at least one cooling element through which cooling medium flows for thermally conductive contacting of its battery cell group.
Vorzugsweise weisen die Kühlmodule jeweils zumindest ein an das Kühlelement angrenzendes Wärmeisolierungsbauteil auf. Dies ermöglicht eine Wärmeisolierung der Kühlelemente und der Batteriezellengruppe.Preferably, the cooling modules each have at least one heat insulating component adjacent to the cooling element. This allows thermal insulation of the cooling elements and the battery cell group.
Das Kühlmittel kann ein phasenwechselndes Kühlfluid sein.The coolant may be a phase change cooling fluid.
Die Aufgabe der Erfindung wird ferner von einer erfindungsgemäßen Fahrzeugbatteriebaugruppe mit einer Fahrzeugbatterie, welche mehrere Batteriezellengruppen aufweist, und einer Kühlvorrichtung gelöst. Die Kühlvorrichtung weist einen gemeinsamen Kühlmittelzulauf und einen gemeinsamen Kühlmittelablauf für einen Kühlmittelkreislauf sowie ein Verteilersystem auf, wobei das Verteilersystem einen Verteiler, einen Kühlmittelsammler und mehrere Kühlmittelzuleitungen und Kühlmittelrückleitungen umfasst. Mehrere Kühlmodule mit jeweils zumindest einem mit Kühlmittel durchströmten Kühlelement, welches eine Kühlfläche hat, die mit der Batteriezellengruppe wärmeleitend, vorzugsweise unmittelbar in Kontakt ist, sind vorgesehen. Den Kühlmodulen sind jeweils eine eigene Kühlmittelzuleitung und eine eigene Kühlmittelrückleitung des Verteilersystems zugeordnet, wobei jeweils ein Kühlmodul einer Batteriezellengruppe zugeordnet ist.The object of the invention is further achieved by a vehicle battery assembly according to the invention with a vehicle battery, which has a plurality of battery cell groups, and a cooling device. The cooling device has a common coolant inlet and a common coolant outlet for a coolant circuit and a distributor system, wherein the distributor system comprises a distributor, a coolant collector and a plurality of coolant supply lines and coolant return lines. A plurality of cooling modules, each having at least one coolant element through which coolant flows, which has a cooling surface which is in heat-conducting, preferably directly in contact, with the battery cell group are provided. The cooling modules are each assigned its own coolant supply line and its own coolant return line of the distributor system, one cooling module each being assigned to one battery cell group.
