Der Erfindung liegt die Aufgabe zugrunde, ein Kraftfahrzeug mit mindestens einer Fensterscheibe im Heckbereich anzugeben, bei dem ein Solargenerator mit hoher Leistungsfähigkeit realisiert werden kann.Of the Invention is based on the object, a motor vehicle with at least a window pane in the rear area, in which a solar generator with high efficiency can be realized.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst.These The object is achieved by the Characteristics of claim 1 solved.
Vorteilhafte Ausgestaltungen der Erfindung sind Bestandteil der weiteren Patentansprüche.advantageous Embodiments of the invention are part of the further claims.
Erfindungsgemäß ist zumindest ein (wesentlicher) Teilbereich der Glasfläche (Verglasung) mindestens einer Fensterscheibe im Heckbereich des Kraftfahrzeugs mit teiltransparenten, einen Solargenerator bildenden Solarzellen bedeckt. Vorzugsweise wird hierbei ein signifikanter Teilbereich der der Heckscheibe des Kraftfahrzeugs als Solargenerator ausgebildet, insbesondere wird zumindest der obere Bereich (bsp. mindestens ein Drit tel der oberen Fläche) der Glasfläche (Verglasung) der Heckscheibe mit teiltransparenten Solarzellen bedeckt (hierdurch ist gleichzeitig ein Schutz der Insassen des Kraftfahrzeugs vor direkter Sonneneinstrahlung gegeben), vorzugsweise wird jedoch die gesamte Fläche der Heckscheibe mit teiltransparenten Solarzellen bedeckt. Zusätzlich oder alternativ kann auch zumindest ein Teilbereich der Glasfläche (Verglasung) mindestens einer Seitenscheibe im Heckbereich des Kraftfahrzeugs mit teiltransparenten Solarzellen bedeckt werden, vorzugsweise wird auch hier die gesamte Fläche der Seitenscheibe im Heckbereich mit teiltransparenten Solarzellen bedeckt. Die teiltransparenten Solarzellen des Solargenerators bedecken insgesamt vorzugsweise eine Fläche von mindestens 0.25 m2, insbesondere wird zur Realisierung einer hohen Leistungsfähigkeit des Solargenerators eine Fläche von ca. 1 m2 mit teiltransparenten Solarzellen bedeckt.According to the invention, at least one (essential) subregion of the glass surface (glazing) of at least one window pane in the rear region of the motor vehicle is covered with partially transparent solar cells forming a solar generator. Preferably, in this case a significant portion of the rear window of the motor vehicle is designed as a solar generator, in particular at least the upper area (eg at least a third tel the upper surface) of the glass surface (glazing) of the rear window with partially transparent solar cells covered (thereby at the same time is a protection of Occupants of the motor vehicle from direct sunlight given), but preferably the entire surface of the rear window is covered with semi-transparent solar cells. Additionally or alternatively, at least a portion of the glass surface (glazing) of at least one side window in the rear of the motor vehicle can be covered with partially transparent solar cells, preferably also the entire surface of the side window in the rear area is covered with partially transparent solar cells. The partially transparent solar cells of the solar generator preferably cover an area of at least 0.25 m 2 in total, in particular an area of approximately 1 m 2 is covered with partially transparent solar cells in order to realize a high efficiency of the solar generator.
Die teiltransparenten Solarzellen des Solargenerators werden so ausgebildet, dass die Glasfläche (Verglasung) mindestens einer Seitenscheibe im Heckbereich des Kraftfahrzeugs einen Transmissionsgrad im Bereich von 10% bis 50%, vorzugsweise jedoch einen Transmissionsgrad im Bereich von 10% bis 30% aufweist. Hierdurch ist weiterhin eine gute Sicht aus dem Innenraum durch die jeweilige Seitenscheibe im Heckbereich gegeben.The semi-transparent solar cells of the solar generator are designed to that the glass surface (Glazing) at least one side window in the rear of the motor vehicle a transmittance in the range of 10% to 50%, but preferably has a transmittance in the range of 10% to 30%. hereby is still a good view of the interior through the respective Side window in the rear area given.
Im Kraftfahrzeug ist weiterhin ein Solarenergiespeicher vorgesehen, der durch die vom Solargenerator gelieferte Energie aufgeladen wird; vorzugsweise wird die Speicherkapazität des Solarenergiespeichers so gewählt, dass in etwa der von der Solarstrahlung gelieferte Energieertrag eines Tages gespeichert werden kann. Der Solarenergiespeicher kann insbesondere als die das Bordnetz des Kraftfahrzeugs versorgende Fahrzeugbatterie (diese Fahrzeugbatterie mit einer Speicherkapazität von bsp. 100 Ah wird über einen DC-DC-Wandler vom Solargenerator geladen) oder als Zusatzbatterie (die Speicherkapazität der Zusatzbatterie beträgt bei einer Batteriespannung von 12 V bsp. 20 Ah bei einer Speicherkapazität der Fahrzeugbatterie von bsp. 80 Ah) oder als Speicherkondensator ausgebildet sein (die Speicherkapazität des bsp. als Super-Cap ausgebildeten Speicherkondensators beträgt bsp. mindestens 50 kJ).in the Motor vehicle is further provided a solar energy storage, which is charged by the energy supplied by the solar generator; Preferably, the storage capacity of the solar energy storage chosen so that about the energy yield delivered by the solar radiation can be saved one day. The solar energy storage can in particular as the supplying the electrical system of the motor vehicle Vehicle battery (this vehicle battery with a storage capacity of bsp. 100 Ah will be over a DC-DC converter from the solar generator charged) or as an additional battery (the storage capacity the additional battery is at a battery voltage of 12 V bsp. 20 Ah at a storage capacity of the vehicle battery from bsp. 80 Ah) or be designed as a storage capacitor (the memory of the bsp. formed as a super-cap storage capacitor is bsp. at least 50 kJ).
Die auf der Glasfläche der Heckscheibe des Kraftfahrzeugs angeordneten teiltransparenten Solarzellen des Solargenerators können die Heizelemente einer heizbaren Heckscheibe bilden (d.h. als Heizfläche einer Widerstandsheizung ausgebildet sein), wobei in diesem Falle der Solarenergiespeicher die teiltransparenten Solarzellen des Solargenerators mit Spannung versorgt; zur Spannungsversorgung des als Heckscheibenheizung fungierenden Solargenerator ist zwischen dem Solargenerator und dem Solarenergiespeicher ein bidirektionaler DC-DC-Wandler geschaltet. Vorzugsweise wird hierbei die gesamte Fläche der Heckscheibe mit teiltransparenten heizbaren Solarzellen bedeckt, so dass hierdurch die gesamte Fläche der Heckscheibe beheizbar ist.The on the glass surface the rear window of the motor vehicle arranged semi-transparent Solar cells of the solar generator, the heating elements of a heatable rear window (i.e., as the heating surface of a resistance heater be formed), in which case the solar energy storage the semi-transparent solar cells of the solar generator with voltage provided; for supplying power to the solar generator acting as a rear window heater is between the solar generator and the solar energy storage bidirectional DC-DC converter switched. Preferably, this is the entire area the rear window is covered with semi-transparent heatable solar cells, so that thereby the entire area the rear window is heated.
