Description
Die vorliegende Erfindung betrifft ein Verfahren zum Temperieren elektrischer Komponenten eines Fahrzeugs gemäß den Merkmalen des Patentanspruches 1 sowie ein Fahrzeug gemäß den Merkmalen des Patentanspruches 5.The present invention relates to a method for tempering electrical components of a vehicle according to the features of
Elektro- bzw. Hybridfahrzeuge weisen einen Hochvoltspeicher mit einem Hochvoltspeichergehäuse auf, in dem mehrere elektrische Speicherzellen angeordnet sind. Während des Betriebs eines solchen Fahrzeugs sowie beim Laden der Speicherzellen erwärmen sich die Speicherzellen. Aus Sicherheitsgründen und um eine möglichst lange „Lebensdauer“ der Speicherzellen zu erreichen, muss die Temperatur der Speicherzellen auf einem Temperaturniveau von weniger als ca. 50° Grad gehalten werden, d. h. die Speicherzellen müssen gekühlt werden. Umgekehrt, wenn das Fahrzeug bei winterlichen Bedingungen relativ lange abgestellt wurde und die Speicherzellen kalt sind, sollten die Speicherzellen möglichst schnell ihr „Idealbetriebstemperaturniveau“ erreichen.Electric or hybrid vehicles have a high-voltage storage device with a high-voltage storage device housing, in which a plurality of electrical storage cells are arranged. The memory cells heat up during the operation of such a vehicle and when the memory cells are being charged. For safety reasons and in order to achieve the longest possible “lifespan” of the storage cells, the temperature of the storage cells must be kept at a temperature level of less than approx. 50 ° degrees. H. the storage cells must be cooled. Conversely, if the vehicle has been parked for a relatively long time in wintry conditions and the storage cells are cold, the storage cells should reach their "ideal operating temperature level" as quickly as possible.
Aufgabe der Erfindung ist es, ein Verfahren zum Temperieren elektrischer Komponenten eines Fahrzeugs sowie ein Fahrzeug zu schaffen, das energetisch günstig ist bzw. das eine kompakte Bauweise ermöglicht.The object of the invention is to provide a method for tempering electrical components of a vehicle and a vehicle which is energetically favorable or which enables a compact design.
Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 bzw 5 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.This object is solved by the features of
Ausgangspunkt des erfindungsgemäßen Verfahrens zum Temperieren elektrischer Komponenten eines Fahrzeugs ist ein Hochvoltspeicher mit einem Hochvoltspeichergehäuse, in dem mehrere elektrische, zu beheizende oder zu kühlende Speicherzellen angeordnet sind. „Zu beheizende oder zu kühlende Speicherzellen“ ist so zu verstehen, dass die Speicherzellen in manchen Betriebszuständen beheizt werden müssen, nämlich dann, wenn diese noch relativ kalt sind, d. h. ihr Idealbetriebstemperaturniveau noch nicht erreicht haben, und in machen Betriebszuständen gekühlt werden müssen, um nicht zu überhitzen.The starting point of the method according to the invention for tempering electrical components of a vehicle is a high-voltage storage device with a high-voltage storage housing, in which a plurality of electrical, heated or cooled storage cells are arranged. “Storage cells to be heated or cooled” should be understood to mean that the storage cells have to be heated in some operating states, namely when they are still relatively cold, ie. H. have not yet reached their ideal operating temperature level and need to be cooled in some operating states in order not to overheat.
Ein wesentlicher Gedanke der Erfindung besteht darin, dass innerhalb des Hochvoltspeichergehäuses zusätzlich zu den elektrischen Speicherzellen mindestens eine zu kühlende elektrische Komponente angeordnet ist. Bei der mindestens zu kühlenden Komponente kann es sich z. B. um ein Ladegerät, einen Gleichspannungswandler (DC/DC-Wandler), ein elektronisches Steuergerät, eine Schützanordnung o.ä. handeln.An essential idea of the invention is that at least one electrical component to be cooled is arranged in the high-voltage storage housing in addition to the electrical storage cells. In the component to be cooled at least, it can be, for. B. a charger, a DC converter (DC / DC converter), an electronic control unit, a contactor arrangement or the like. act.
Ferner ist ein von einem flüssigen Kühlmittel durchströmtes Kühlmittelkanalsystem vorgesehen, das eine Kühlmittelpumpe aufweist, die ebenfalls in dem Hochvoltspeichergehäuse angeordnet ist. Das Kühlmittelkanalsystem bzw. darin strömende flüssige Kühlmittel ist thermisch direkt oder indirekt mit den Speicherzellen und mit der mindestens einen zu kühlenden elektrischen Komponente gekoppelt.Furthermore, a coolant channel system through which a liquid coolant flows is provided, which has a coolant pump, which is also arranged in the high-voltage storage housing. The coolant channel system or liquid coolant flowing therein is thermally coupled directly or indirectly to the storage cells and to the at least one electrical component to be cooled.
Klarstellend sei erwähnt, dass es sich bei dem flüssigen Kühlmittel um ein Kühlmittel handelt, das in allen auftretenden Betriebszuständen flüssig ist. Es handelt sich also nicht etwa um ein Kältemittel (wie es z.B. bei Klimaanlagen zum Einsatz kommt), das teilweise gasförmig und flüssig oder rein gasförmig ist. Bei dem erfindungsgemäßen Kühlmittel kann es sich beispielsweise um Wasser handeln, welches mit einem Frostschutzmittel versetzt ist.To clarify, it should be mentioned that the liquid coolant is a coolant that is liquid in all operating states that occur. So it is not a refrigerant (as used in air conditioning systems, for example), which is partly gaseous and liquid or purely gaseous. The coolant according to the invention can, for example, be water which is mixed with an antifreeze.
Ein zentraler Gedanke des erfindungsgemäßen Verfahrens besteht darin, dass in einem ersten Betriebszustand, in dem die Speicherzellen eine Temperatur haben, die kleiner als eine vorgegebene erste Temperatur ist, von der mindestens einen zu kühlenden elektrischen Komponente abgegebene Wärme über das Kühlmittel an die Speicherzellen abgegeben wird. Wenn sich also das Fahrzeug bzw. der Hochvoltspeicher bzw. die darin angeordneten elektrischen Speicherzellen in einem „kalten Zustand“ befinden, müssen die Speicherzellen möglichst schnell auf ein Idealbetriebstemperaturniveau erwärmt werden, um sicherzustellen, dass das Fahrzeug bzw. der elektrische Antrieb optimal leistungsfähig ist.A central idea of the method according to the invention is that in a first operating state, in which the storage cells have a temperature that is lower than a predetermined first temperature, heat is given off by the at least one electrical component to be cooled via the coolant to the storage cells , If the vehicle or the high-voltage battery or the electrical storage cells arranged in it are in a "cold state", the storage cells must be heated to an ideal operating temperature level as quickly as possible to ensure that the vehicle or the electric drive is optimally efficient.
Der Grundgedanke der Erfindung besteht darin, zum Aufwärmen der Speicherzellen Wärme, die von der mindestens einen zu kühlenden elektrischen Komponente bereits unmittelbar nach dem „Starten“ abgegeben wird, zu nutzen, um damit die Speicherzellen möglichst schnell aufzuheizen, d.h. möglichst schnell auf ihr Idealbetriebstemperaturniveau zu bringen. Die Wärmeenergie wird dabei über das flüssige Kühlmittel von der mindestens einen elektrischen Komponente zu den Speicherzellen übertragen. Eine derartige elektrische Komponente, bei der sich z. B. um ein Ladegerät, einen Gleichspannungswandler, um ein elektronisches Steuergerät, eine Schutzanordnung o.ä. handeln kann, können relativ hohe Temperaturniveaus, z. B. bis zu 90°C oder mehr, erreichen. Dadurch können beträchtliche Wärmeleistungen entstehen, die zum Aufheizen der Speicherzellen verwendet können.The basic idea of the invention is to use heat, which is emitted by the at least one electrical component to be cooled immediately after the "start", to warm up the storage cells in order to heat the storage cells as quickly as possible, i.e. to bring them to their ideal operating temperature level as quickly as possible. The thermal energy is transferred from the at least one electrical component to the storage cells via the liquid coolant. Such an electrical component in which z. B. a charger, a DC converter, an electronic control unit, a protective arrangement or the like. can act, relatively high temperature levels, e.g. B. up to 90 ° C or more. This can result in considerable heat outputs that can be used to heat the storage cells.
Nach einer Weiterbildung der Erfindung ist vorgesehen, dass in dem ersten Betriebszustand, der auch als „Aufheizzustand“ der Speicherzellen bezeichnet werden kann, Kühlmittel ausschließlich innerhalb des im Hochvoltspeichergehäuse vorgesehenen Kühlmittelkanalsystems umgepumpt bzw. umgewälzt wird. Der hierfür erforderliche Kühlmittevolumenstrom wird durch die innerhalb des Hochvoltspeichergehäuses angeordnete Kühlmittelpumpe erzeugt.According to a development of the invention, it is provided that in the first operating state, which can also be referred to as the “heating state” of the storage cells, coolant is pumped or circulated exclusively within the coolant duct system provided in the high-voltage storage housing. The one required for this Coolant volume flow is generated by the coolant pump arranged inside the high-voltage storage housing.
Nach einer Weiterbildung der Erfindung wird in einem zweiten Betriebszustand, in dem die Speicherzellen eine Temperatur haben, die größer als eine vorgegebene zweite Temperatur ist, Wärme, die von der mindestens einen zu kühlenden elektrischen Komponente und von den Speicherzellen an das Kühlmittel abgegeben wird, mittels des Kühlmittels aus dem Hochvoltspeichergehäuse heraus transportiert und dort über einen Wärmetaucher abgegeben. Der zweite Betriebszustand ist also ein Betriebszustand, in dem sowohl die mindestens eine elektrische Komponente als auch die Speicherzellen gekühlt werden müssen. Im zweiten Betriebszustand haben die Speicherzellen also eine Temperatur, die im oberen Bereich des Idealbetriebstemperaturbereichs liegt oder die genau der oberen Idealbetriebstemperatur entspricht.According to a development of the invention, in a second operating state, in which the storage cells have a temperature that is greater than a predetermined second temperature, heat is emitted by the at least one electrical component to be cooled and by the storage cells to the coolant of the coolant is transported out of the high-voltage storage housing and released there via a heat exchanger. The second operating state is therefore an operating state in which both the at least one electrical component and the memory cells have to be cooled. In the second operating state, the storage cells therefore have a temperature which is in the upper range of the ideal operating temperature range or which corresponds exactly to the upper ideal operating temperature.
Nach einer Weiterbildung der Erfindung ist vorgesehen, dass in dem zweiten Betriebszustand Wärme, die von der mindestens einen elektrischen Komponente und den Speicherzellen an das Kühlmittel abgegeben wird, mittels des Kühlmittels aus dem Hochvoltspeichergehäuse heraus transportiert wird und dort über einen Wärmetauscher entweder an die Umgebung oder an einen anderen „Wärmekreislauf des Fahrzeugs oder unmittelbar an eine andere Komponente des Fahrzeugs abgegeben wird. Der hierfür erforderliche Kühlmittelvolumenstrom in das im Inneren des Hochvoltspeichergehäuses befindliche Kühlmittelkanalsystem hinein und aus dem Kühlmittelkanalsystem heraus wird durch eine weitere Kühlmittelpumpe erzeugt, die außerhalb des Hochvoltspeichergehäuses angeordnet ist.According to a development of the invention, it is provided that in the second operating state, heat which is released from the at least one electrical component and the storage cells to the coolant is transported out of the high-voltage storage housing by means of the coolant and there either to the environment or via a heat exchanger is given to another “heat cycle of the vehicle or directly to another component of the vehicle. The coolant volume flow required for this into the coolant channel system located inside the high voltage storage housing and out of the coolant channel system is generated by a further coolant pump which is arranged outside the high voltage storage housing.
