Description
Die Erfindung betrifft ein Fahrzeug, das mit elektrischer Energie betreibbar ist, insbesondere Personenkraftwagen, Lastkraftwagen und Busse.The invention relates to a vehicle which can be operated with electrical energy, in particular passenger cars, trucks and buses.
Elektrofahrzeug sind bekannt und werden unter dem Druck des Klimawandels zunehmend hergestellt und verwendet.Electric vehicles are well known and increasingly manufactured and used under the pressure of climate change.
Problematisch bei der Nutzung der Elektrofahrzeuge ist die begrenzte Infrastruktur an Ladestationen für die Energiespeicher dieser Fahrzeuge.The problem with the use of electric vehicles is the limited infrastructure of charging stations for the energy storage devices in these vehicles.
Neben der Entwicklung von Energiespeichern mit einer höheren Kapazität gibt es auch Entwicklungen, die auf regenerative Energiequellen, vor allem Solarstrom, zurückgreifen.In addition to the development of energy storage devices with a higher capacity, there are also developments that make use of regenerative energy sources, especially solar power.
So werden in der

Um die Effizienz von Kraftfahrzeugen zu steigern, werden weiter rekuperative Systeme genutzt. Ein solches System ist die Rekuperationsbremse, bei der Bewegungsenergie in elektrische Energie umgewandelt und einem Energiespeicher zugeführt wird (u. a.
Die
Nachteilig bei diesen technischen Lösungen ist die Parallelität der Entwicklung, nämlich einerseits gerichtet auf regenerative Energiequellen bzw. auf rekuperative Systeme und andererseits auf den Ausbau von Ladestationen.The disadvantage of these technical solutions is the parallel development, namely on the one hand directed towards regenerative energy sources or on recuperative systems and on the other hand towards the expansion of charging stations.
Aufgabe der Erfindung ist es, ein elektrisches Antriebssystem vorzuschlagen, das auf Ladestationen weitestgehend verzichten kann, in dem die vorhandenen Energiequellen in vollem Umfang genutzt werden.The object of the invention is to propose an electric drive system which can largely do without charging stations, in which the available energy sources are used to the full.
Gelöst wird diese Aufgabe mit den Merkmalen des Anspruches 1. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.This object is achieved with the features of
Bei einem elektrischen Antriebssystem für Fahrzeuge unter Nutzung von Solarenergie, die einem Energiespeicher des Fahrzeuges zugeführt und/oder direkt zum Antrieb von mindestens einem Elektromotor für den Radantrieb genutzt wird, wird erfindungsgemäß vorgeschlagen, dass die Kapazität der für den Radantrieb benötigten Solarenergie durch die Erzeugung und Zuführung rekuperativer Energie und Windenergie ergänzbar ist.In an electric drive system for vehicles using solar energy, which is fed to an energy store of the vehicle and / or used directly to drive at least one electric motor for the wheel drive, it is proposed according to the invention that the capacity of the solar energy required for the wheel drive is generated by the generation and Supply of recuperative energy and wind energy can be supplemented.
Zur Erzeugung der rekuperativen Energie sind die Räder, einschließlich der elektrisch angetriebenen, mit einem Generator mit Rotor und Stator ausgerüstet, der bevorzugt bei Bergabfahrt und/oder bei im Wesentlichen horizontaler Fahrt zuschaltbar ist.
Bei einer bevorzugten Ausführung ist vorgesehen, dass als Rotor des Generators die vorhandene Bremsscheibe des Rades eingesetzt ist und der Stator am Bremssattel angeordnet ist.To generate the recuperative energy, the wheels, including the electrically driven ones, are equipped with a generator with rotor and stator, which can preferably be switched on when driving downhill and / or when driving essentially horizontally.
In a preferred embodiment it is provided that the existing brake disc of the wheel is used as the rotor of the generator and the stator is arranged on the brake caliper.
Alternativ kann der Generator auch als eigenständige Baueinheit ausgebildet und mit der Antriebswelle bzw. Lagerwelle für das jeweilige Rad gekoppelt sein. Vorteilhaft ist es bei dieser Ausführung, wenn dem Generator ein Übersetzungsgetriebe zur Drehzahlregulierung vorgeschaltet ist.Alternatively, the generator can also be designed as an independent structural unit and coupled to the drive shaft or bearing shaft for the respective wheel. It is advantageous in this embodiment if a transmission gear for speed regulation is connected upstream of the generator.
Als weitere Energiequelle nutzt das Antriebssystem den Wind, insbesondere den Fahrtwind.The drive system uses the wind as a further source of energy, in particular the head wind.
So ist vorgesehen, dass im Fahrzeugfrontbereich Ventilatoren angeordnet sind, die insbesondere vom Fahrtwind antreibbar sind und deren Rotationsbewegung in elektrischer Energie umwandelbar und dem oder den Energiespeichern zuführbar ist.For example, it is provided that fans are arranged in the front area of the vehicle, which can be driven in particular by the head wind and whose rotational movement can be converted into electrical energy and fed to the energy storage device (s).
Mittig im Fahrzeugfrontbereich werden bevorzugt Axialventilatoren eingesetzt sind, während im Bereich der Außenkanten des Fahrzeugfrontbereiches Radialventilatoren genutzt werden.Axial fans are preferably used in the center of the vehicle front area, while radial fans are used in the area of the outer edges of the vehicle front area.
Eine weitere vorteilhafte Ausgestaltung sieht vor, dass die Abdeckung des Frontbereiches (entspricht der heutigen Motorhaube) nach außen ausgeformte Schlitze aufweist, deren Öffnungen nach vorn gerichtet sind, so dass durch die Schlitze Wind nach unterhalb der Abdeckung leitbar ist, wo Radialventilatoren zur Stromerzeugung angeordnet sind.A further advantageous embodiment provides that the cover of the front area (corresponds to today's engine hood) has outwardly shaped slots, the openings of which are directed to the front, so that wind can be guided through the slots below the cover, where centrifugal fans are arranged to generate electricity .
Um die vorhandenen Oberflächen des Fahrzeuges optimal für die Erzeugung von Solarenergie zu nutzen, ist vorgesehen, dass mit Solarzellen bestückt sind: das Fahrzeugdach und/oder Aufbauten auf dem Dach, wie Dachgepäckträger, und/oder die Heckscheibe und/oder die Kofferklappe bei Personenkraftwagen und das Dach und die Seitenwände von Kofferaufbauten bei Lastkraftwagen und Sprintern sowie bei Bussen.In order to optimally use the existing surfaces of the vehicle for the generation of solar energy, provision is made for solar cells to be fitted: the vehicle roof and / or structures on the roof, such as roof racks, and / or the rear window and / or the trunk lid in passenger cars and the roof and side walls of box bodies on trucks and sprinters as well as on buses.
Um einen möglichst hohen Wirkungsgrad bei der Solarenergieerzeugung zu erzielen, werden PWM und/oder MPPT Solarladeregler eingesetzt.In order to achieve the highest possible efficiency in solar energy generation, PWM and / or MPPT solar charge controllers are used.
Vorteilhaft ist es auch, wenn Solarzellenfolien mit lichtsammelnden und lichtemittierenden Pigmenten sowie Photovoltaikmaterialien eingesetzt sind.
Diese haben den Vorteil, dass sie auch ohne unmittelbare Sonneneinstrahlung Energie erzeugen.It is also advantageous if solar cell foils with light-collecting and light-emitting pigments and photovoltaic materials are used.
These have the advantage that they generate energy even without direct sunlight.
Mit dem vorgesehenen elektrischen Antriebssystem ist bei einer entsprechenden Anzahl von Batterien im Wesentlichen die Selbstversorgung der Fahrzeuge mit elektrischer Energie gesichert, so dass auf den Aufbau unzähliger Ladesäulen verzichtet werden kann.With the provided electric drive system, with a corresponding number of batteries, the self-sufficiency of the vehicles with electrical energy is essentially ensured, so that the construction of innumerable charging stations can be dispensed with.
Da elektrische Energie aus verschiedenen Quellen zu speichern und den Radantrieben sowie weiteren Komponenten, die elektrische Energie benötigen, zuzuleiten ist und ein optimierter Abruf der Energie aus verschiedenen Speichern notwendig ist, bedarf es einen entsprechenden Koordinierungseinrichtung für das Energiemanagement.Since electrical energy has to be stored from various sources and fed to the wheel drives and other components that require electrical energy, and an optimized retrieval of energy from various stores is necessary, a corresponding coordination device is required for energy management.
Ausführungsbeispiele der Erfindung sollen anhand der Zeichnungen erläutert werden.Embodiments of the invention will be explained with reference to the drawings.
