Description
Die Erfindung betrifft ein Elektrokraftfahrzeug mit einer Karosserieanordnung, die eine Anzahl von Karosserieteilen aufweist, die zumindest einen Technikraum einschließen, in dem mindestens eine Energiespeichereinrichtung vorgesehen ist, wobei der Technikraum über mindestens einen Lufteinlasskanal mit mindestens einer Lufteinlassöffnung und mindestens einen Luftauslasskanal mit mindestens einer Luftauslassöffnung in den entsprechenden Karosserieteilen zur passiven Kühlung fluidisch mit der Fahrzeugumgebung verbunden ist.The invention relates to an electric motor vehicle with a body arrangement that has a number of body parts that enclose at least one technical compartment in which at least one energy storage device is provided, the technical compartment having at least one air inlet duct with at least one air inlet opening and at least one air outlet duct with at least one air outlet opening in the corresponding body parts for passive cooling is fluidly connected to the vehicle environment.
Derartige Elektrofahrzeuge sind aus dem Stand der Technik hinlänglich bekannt. Die passive Kühlung dient hierbei einer besonders effizienten Kühlung eines Technikraumes, bei der zum Erzeugen des Kühlluftstromes keine Energie aufgewendet werden muss, die die Reichweite des Elektrokraftfahrzeuges verringern würde. Ein Beispiel für ein derartiges Elektrokraftfahrzeug zeigt die deutsche Offenlegungsschrift
Aufgabe der Erfindung ist es daher, den oben genannten Nachteil auf einfache und kostengünstige Weise zu vermeiden.The object of the invention is therefore to avoid the disadvantage mentioned above in a simple and inexpensive manner.
Diese Aufgabe wird dadurch gelöst, dass der Technikraum mit der Energiespeichereinrichtung im Heckbereich der Karosserieanordnung vorgesehen ist, wobei mindestens eine Lufteinlassöffnung in jedem Seitenkarosserieteil der Karosserieanordnung vorgesehen ist. Hierdurch ist es auf einfache Weise möglich, an jeder Seite des Elektrokraftfahrzeuges mindestens eine Lufteinlassöffnung vorzusehen, deren Querschnitt eine Höhe aufweist, die mindestens 70 % der Höhe der mindestens einen Energiespeichereinrichtung entspricht. Dadurch, dass die Energiespeichereinrichtung im Heckbereich vorgesehen ist, können die Lufteinlasskanäle sehr kurz und im Querschnitt groß dimensioniert sein, wodurch eine ausreichende Menge an Außenluft zur Energiespeichereinrichtung geführt werden kann.This object is achieved in that the technical space with the energy storage device is provided in the rear area of the body assembly, with at least one air inlet opening being provided in each side body part of the body assembly. This makes it possible in a simple manner to provide at least one air inlet opening on each side of the electric motor vehicle, the cross section of which has a height that corresponds to at least 70% of the height of the at least one energy storage device. Due to the fact that the energy storage device is provided in the rear area, the air inlet ducts can be very short and have a large cross section, as a result of which a sufficient quantity of outside air can be routed to the energy storage device.
In einer besonders vorteilhaften Ausführungsform ist im Bereich eines Lufteinlasskanales mindestens eine verstellbare Luftleitfläche zur Steuerung der Luftzufuhr vorgesehen. Diese Luftleitfläche kann beispielsweise auch die entsprechende Lufteinlassöffnung bündig abschließen, um eine gute Aerodynamik zu gewährleisten. Durch die verstellbare Luftleitfläche kann die Temperierung der Energiespeichereinrichtung auf einfache Weise angepasst werden. In einer ersten Ausführungsform sind die Luftleitflächen durch mindestens einen elektrischen Aktuator verstellbar. Hierbei ist es beispielsweise denkbar, dass eine Luftleitfläche im linken Seitenkarosserieteil und die entsprechende Luftleitfläche im rechten Seitenkarosserieteil mit einem Aktuator, beispielsweise über ein Gestänge, wirkverbunden sind. In vorteilhafter Weise kann hierbei eine Steuereinrichtung vorgesehen sein, die Steuerungstechnisch mit Temperatursensoren zur Erfassung der Temperatur der Energiespeichereinrichtung und den mindestens einen elektrischen Aktuator verbunden ist.In a particularly advantageous embodiment, at least one adjustable air guiding surface for controlling the air supply is provided in the area of an air intake duct. This air-guiding surface can, for example, also close flush with the corresponding air inlet opening in order to ensure good aerodynamics. The temperature control of the energy storage device can be adjusted in a simple manner by means of the adjustable air guiding surface. In a first embodiment, the air-guiding surfaces can be adjusted by at least one electrical actuator. It is conceivable here, for example, that an air guiding surface in the left-hand side body part and the corresponding air guiding surface in the right-hand side body part are operatively connected to an actuator, for example via a linkage. Advantageously, a control device can be provided here, which is connected in terms of control technology to temperature sensors for detecting the temperature of the energy storage device and the at least one electrical actuator.
Alternativ oder auch zusätzlich können die Luftleitflächen eine Formgedächtnislegierung aufweisen oder durch einen Aktuator aus einer Formgedächtnislegierung verstellbar sein. Hierbei verändert sich die Luftleitfläche beziehungsweise der Aktuator aufgrund der Formgedächtnislegierung in Temperaturabhängigkeit, sodass bei niedrigen Temperaturen der Querschnitt des jeweiligen Lufteinlasskanales verringert wird.Alternatively or additionally, the air guiding surfaces can have a shape memory alloy or be adjustable by an actuator made of a shape memory alloy. The air guide surface or the actuator changes as a function of temperature due to the shape memory alloy, so that the cross section of the respective air intake duct is reduced at low temperatures.
Dadurch, dass eine Ebene, in der eine Lufteinlassöffnung liegt, mit einer Ebene, in der eine Fahrzeuglängsachse verläuft, einen Winkel α = 5° - 60° einschließt, kann die Außenluft sehr gut eingefangen werden und die kinetische Energie aufgrund der Fahrzeuggeschwindigkeit sehr gut genutzt werden, um die Außenluft zur Energiespeichereinrichtung zu führen.Due to the fact that a plane in which an air intake opening is located forms an angle α = 5° - 60° with a plane in which a vehicle longitudinal axis runs, the outside air can be captured very well and the kinetic energy due to the vehicle speed can be used very well be used to direct the outside air to the energy storage device.
In einer besonders vorteilhaften Ausführungsform sind Luftauslassöffnungen im Bereich eines Unterbodenkarosserieteiles und/oder im Bereich einer Heckschürze und/oder im Bereich einer Heckklappe vorgesehen.In a particularly advantageous embodiment, air outlet openings are provided in the area of an underbody body part and/or in the area of a rear apron and/or in the area of a tailgate.
Um eine besonders effiziente Kühlung der Energiespeichereinrichtung zu gewährleisten, ist die Energiespeichereinrichtung aus beabstandeten, Luftkanäle bildenden Einzelbatteriemodulen aufgebaut. Hierbei ist es besonders vorteilhaft, wenn die Batteriemodule Kühlrippen in Form einer Wabenstruktur aufweisen, zwischen denen die Luftkanäle ausgebildet sind.In order to ensure particularly efficient cooling of the energy storage device, the energy storage device is constructed from spaced-apart individual battery modules that form air ducts. It is particularly advantageous here if the battery modules have cooling ribs in the form of a honeycomb structure, between which the air ducts are formed.
In besonders vorteilhafter Weise sind genau zwei Lufteinlassöffnungen an jedem Seitenkarosserieteil vorgesehen. Eine derartige Aufteilung bietet eine Vielzahl von Designtechnischen Lösungen und gewährleistet eine ausreichende Luftzuführung zur Energiespeichereinrichtung.In a particularly advantageous manner, exactly two air inlet openings are provided on each side body part. Such a division offers a variety of design-technical solutions and ensures sufficient air supply to the energy storage device.

Zur effektiven passiven Kühlung der Energiespeichereinrichtung 18 weist das Seitenkarosserieteil 6 im vorliegenden Ausführungsbeispiel zwei Einlassöffnungen 20, 22 auf, die über hier nicht im einzelnen dargestellten Lufteinlasskanäle Außenluft zur Energiespeichereinrichtung 18 führt um diese zu Kühlen. Die Energiespeichereinrichtung 18 besteht hierbei aus beabstandeten Einzelbatteriemodulen 24, zwischen denen, wie in
Um die Außenluft besser „einfangen“ zu können, ist eine Ebene, in der sich die Lufteinlassöffnung 20 befindet unter einem Winkel α von ca. 30° zu einer Ebene in der sich eine Fahrzeuglängsachse 32 befindet angewinkelt.In order to be able to “capture” the outside air better, a plane in which the air inlet opening 20 is located is angled at an angle α of approximately 30° to a plane in which a vehicle
Des Weiteren ist in der Einlassöffnung 20 eine Luftleitfläche 34 dargestellt, die eine Formgedächtnislegierung aufweist, wodurch bei kühler Außentemperatur der Eintrittquerschnitt der Lufteinlassöffnung 20 verringert wird, um die Energiespeichereinrichtung 18 in einem optimalen Temperaturbereich nutzen zu können.Furthermore, an
Im Lufteinlasskanal 40 im Bereich der Lufteinlassöffnung 38 ist auch hier eine Luftleitfläche 46 vorgesehen, die über ein Gestänge 48 mit einem Aktuator 50 wirkverbunden ist, um von einem geschlossenen in einen geöffneten Zustand beziehungsweise von einem geöffneten in einen geschlossenen Zustand verstellt zu werden. Der Aktuator 50 ist hierbei über das Gestänge 48 auch mit der Luftleitfläche 46 des gegenüberliegenden Seitenkarosserieteiles des Elektrokraftfahrzeuges 2 wirkverbunden. Zur Ansteuerung des Aktuators 50 kann eine nicht weiter dargestellte Steuereinrichtung vorgesehen sein, die steuerungstechnisch mit Temperatursensoren zur Erfassung der Temperatur der Energiespeichereinrichtung 18 verbunden ist.In the
Es sollte deutlich sein, dass die Dimensionierungen der Lufteinlassöffnung/-en und Luftauslassöffnung/-en sowie dem oder die zugehörigen Lufteinlasskanal/-kanäle und Luftauslasskanal/-kanäle abhängig von dem für einen optimalen Wärmehaushalt benötigten Volumenstrom sind. Insbesondere kann hierbei über die Position der Luftleitflächen eine Überhitzung im Stand ausgeschlossen werden.It should be clear that the dimensions of the air inlet opening(s) and air outlet opening(s) as well as the associated air inlet duct(s) and air outlet duct(s) depend on the volume flow required for optimal heat management. In particular, overheating when stationary can be ruled out by the position of the air deflectors.
