Description
Die Erfindung betrifft einen elektrischen Energiespeicher eines teilweise elektrisch betriebenen Kraftfahrzeugs gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to an electrical energy store of a partially electrically operated motor vehicle according to the preamble of claim 1.
Elektrische Energiespeicher können im Falle eines thermischen Durchgehens einer, beispielsweise Li-Ionen Zelle, überhitzt werden, wodurch ein Brand resultieren kann. Zur Vermeidung eines solchen Resultates soll ein Anstecken beziehungsweise eine Propagation anderer benachbarter Li-Ionen Zellen verhindert werden. Dies ist vermeidbar, indem die durch das thermische Durchgehen der Zelle ausströmende Heißgase und die Elektrolyte gezielt weggeleitet werden, sowie auch die daraus entstehende Wärme. Bei den derzeit gängigen Zellmodulen findet eine Entlüftung nur bei eingeschalteten Kraftfahrzeugen statt, wodurch die Zellen mittels einer laufenden Kühlmittelpumpe gekühlt werden. Die im thermischen Durchgehen entstehenden Heißgase werden zumeist nicht gekühlt. Derzeitige elektrische Energiespeicher, wie beispielsweise Lithium-Ionen Batterien, nutzen zumeist eine indirekte Kühlung. Bei einem ausgeschalteten Kraftfahrzeug findet demnach keine Kühlung von Zellmodulen mittels der Kühlmittelpumpe innerhalb des elektrischen Energiespeichers statt. Bei einem thermischen Durchgehen eines einzelnen Zellmoduls, ist die Wahrscheinlichkeit einer Ansteckung beziehungsweise einer Propagation groß und dadurch auch eine Überhitzung des gesamten elektrischen Energiespeichers, welche beispielsweise zu dem zuvor genannten Brand und/oder zu der Explosion führen könnte.Electrical energy storage devices can be overheated in the event of a thermal runaway cell, for example a Li-ion cell, which can result in a fire. To avoid such a result, the plugging or propagation of other neighboring Li-ion cells should be prevented. This can be avoided in that the hot gases and the electrolytes flowing out due to the thermal passage of the cell are specifically diverted away, as well as the resulting heat. In the case of the currently common cell modules, ventilation only takes place when the motor vehicle is switched on, as a result of which the cells are cooled by means of a running coolant pump. The hot gases that arise during thermal runaway are mostly not cooled. Current electrical energy storage devices, such as lithium-ion batteries, mostly use indirect cooling. When the motor vehicle is switched off, there is accordingly no cooling of cell modules by means of the coolant pump within the electrical energy store. In the event of a thermal runaway of an individual cell module, there is a high probability of infection or propagation and, as a result, overheating of the entire electrical energy store, which could lead, for example, to the aforementioned fire and / or to the explosion.
Die aus der
Aufgabe der vorliegenden Erfindung ist es, einen elektrischen Energiespeicher eines teilweise elektrisch betriebenen Kraftfahrzeugs der eingangs genannten Art derart weiterzuentwickeln, dass eine passive Kühlung des elektrischen Energiespeichers möglich ist.The object of the present invention is to further develop an electrical energy store of a partially electrically operated motor vehicle of the type mentioned at the beginning in such a way that passive cooling of the electrical energy store is possible.
Diese Aufgabe wird durch einen elektrischen Energiespeicher mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen Weiterbildungen der Erfindung sind in den übrigen Ansprüchen angegeben.This object is achieved by an electrical energy store with the features of claim 1. Advantageous configurations with expedient developments of the invention are specified in the remaining claims.
Die Erfindung betrifft einen elektrischen Energiespeicher eines teilweise elektrisch betriebenen Kraftfahrzeugs, mit zumindest einem Energiespeichergehäuse, in dessen Innenraum zumindest ein Zellmodul angeordnet ist. Der elektrische Energiespeicher umfasst zudem noch eine fluidisch betriebene Kühleinrichtung mit einem Kühlkreislauf, welche dazu ausgebildet ist, in einem ersten Betriebsmodus des elektrischen Energiespeichers mittels einer Förderpumpe der Kühleinrichtung aktiv ein Kühlfluid in den Innenraum zu befördern. Weiterhin umfasst der elektrische Energiespeicher eine an dem Energiespeichergehäuse ausgebildete einstellbare Austrittsöffnung, welche dazu ausgebildet ist, bei einem thermischen Durchgehen des zumindest einen Zellmoduls das Energiespeichergehäuse gegenüber einer Umgebung des elektrischen Energiespeichers zu öffnen. Die Kühleinrichtung befördert in einem zweiten Betriebsmodus der elektrische Energiespeicher, in welchem die Förderpumpe passiv und die einstellbare Austrittsöffnung geöffnet ist, das Kühlfluid in den Innenraum des Energiespeichergehäuses und durch eine einstellbare Austrittsöffnung in die Umgebung des elektrischen Energiespeichers. Dies findet auf Basis eines mechanisch erzeugten Systemüberdrucks des Kühlfluides im Kühlkreislauf statt. Mittels eines Strömungsverlaufs des Kühlfluids durch die Förderpumpe wird eine passive Kühlung ermöglicht. Aktive Systeme, wie beispielsweise Temperaturüberwachungen oder einem Einschalten eines Kühlsystems, erfordern einen hohen Strombedarf und hohe sogenannte Aufwach-Raten, um eine schnelle Reaktion auf ein thermisches Durchgehen zu ermöglichen. Mittels einer passiven Kühlung ist es möglich diese Vorgehensweisen zu umgehen.The invention relates to an electrical energy store of a partially electrically operated motor vehicle, with at least one energy storage housing, in the interior of which at least one cell module is arranged. The electrical energy store also includes a fluidically operated cooling device with a cooling circuit, which is designed to actively convey a cooling fluid into the interior by means of a feed pump of the cooling device in a first operating mode of the electrical energy store. Furthermore, the electrical energy store comprises an adjustable outlet opening formed on the energy storage housing, which is designed to open the energy storage housing with respect to the surroundings of the electrical energy store in the event of a thermal runaway of the at least one cell module. In a second operating mode of the electrical energy store, in which the feed pump is passive and the adjustable outlet opening is open, the cooling device conveys the cooling fluid into the interior of the energy storage housing and through an adjustable outlet opening into the vicinity of the electrical energy store. This takes place on the basis of a mechanically generated system overpressure of the cooling fluid in the cooling circuit. Passive cooling is made possible by means of a flow path of the cooling fluid through the feed pump. Active systems, such as temperature monitoring or switching on a cooling system, require a high power consumption and high so-called wake-up rates in order to enable a quick reaction to a thermal runaway. It is possible to circumvent these procedures by means of passive cooling.
Eine weitere vorteilhafte Ausführungsform sieht vor, dass die dem elektrischen Energiespeicher angeordneten, einstellbare Austrittsöffnung als eine Berstscheibe ausgebildet ist.Another advantageous embodiment provides that the adjustable outlet opening arranged on the electrical energy store is designed as a rupture disk.
In einer weiteren vorteilhaften Ausgestaltung der Erfindung ist es vorgesehen, dass der im zweiten Betriebsmodus mechanisch erzeugte Systemüberdruck des Kühlfluides im Kühlkreislauf mittels eines oberhalb des elektrischen Energiespeichers positionierten Ausgleichsbehälters erzeugt wird.In a further advantageous embodiment of the invention, it is provided that the system overpressure of the cooling fluid, which is mechanically generated in the second operating mode, is generated in the cooling circuit by means of an expansion tank positioned above the electrical energy store.
Eine weitere vorteilhafte Ausführungsform sieht vor, dass der Ausgleichsbehälter wenigstens ein Kolbenelement umfasst.Another advantageous embodiment provides that the expansion tank comprises at least one piston element.
In einer weiteren vorteilhaften Ausgestaltung der Erfindung ist es vorgesehen, dass der Ausgleichsbehälter wenigstens ein Federelement umfasst.In a further advantageous embodiment of the invention it is provided that the expansion tank comprises at least one spring element.
Eine weitere vorteilhafte Ausführungsform sieht vor, dass der Ausgleichsbehälter wenigstens eine druckregulierende Entlüftungsöffnung umfasst.Another advantageous embodiment provides that the expansion tank comprises at least one pressure-regulating ventilation opening.
