Description
Die vorliegende Erfindung betrifft ein kombiniertes Antriebsaggregat, insbesondere ein kombiniertes Antriebsaggregat, das eine Brennstoffzelle mit sekundären Stromquellen vereinigt und in Fahrzeugen Anwendung findet.The The present invention relates to a combined drive unit, in particular a combined drive unit, which has a fuel cell with secondary Power sources combined and used in vehicles.
Methanol-Brennstoffzellen erzeugen in einer Oxydationsreaktion elektrischen Strom auf effiziente Weise und erfüllen somit heutige Ansprüche an einen Ersatzenergieträger für Kraftfahrzeuge. In konventioneller Technik werden zur Reduzierung des Erdölverbrauchs Hybridsysteme eingesetzt, die Benzinmotoren und Elektromotoren kombinieren, wobei sich kinetische Energie von Kraftfahrzeugen beim Bremsen rückgewinnen läßt. Benzinmotoren nehmen jedoch großen Raum ein und sind in ihrem Wirkungsgrad begrenzt. Eine weitere Reduzierung des Gesamtwirkungsgrads erfolgt durch wiederholtes Umwandeln von elektrischer Energie in mechanische Energie und umgekehrt. Es besteht daher ein Bedarf an einer kombinierten Energiequelle, die primär eine Brennstoffzelle und sekundär konventionelle Stromquellen aufweist.Methanol fuel cells generate electric current in an efficient manner in an oxidation reaction and fulfill thus today's claims to a replacement energy carrier for motor vehicles. In conventional technology are used to reduce oil consumption Used hybrid systems combining gasoline engines and electric motors, wherein kinetic energy of motor vehicles recover during braking leaves. petrol engines but take big Space and are limited in their efficiency. Another reduction the overall efficiency is achieved by repeatedly converting from electrical energy into mechanical energy and vice versa. It exists therefore, a need for a combined power source, primarily a fuel cell and secondarily having conventional power sources.
Die wesentliche Aufgabe der vorliegenden Erfindung besteht darin, ein kombiniertes Antriebsaggregat zu schaffen, das eine Brennstoffzelle mit sekundären Stromquellen vereinigt und in Fahrzeugen Anwendung findet.The essential object of the present invention is a Combined drive unit to create a fuel cell with secondary Power sources combined and used in vehicles.
Eine weitere Aufgabe der vorliegenden Erfindung besteht darin, ein kombiniertes Antriebsaggregat zu schaffen, das ein Steuern von Brennstoffzufuhr und Stromabnahme je nach Belastung erlaubt.A Another object of the present invention is to provide a combined To create a drive unit that controls fuel supply and current consumption allowed depending on load.
Eine weitere Aufgabe der vorliegenden Erfindung besteht darin, ein kombiniertes Antriebsaggregat zu schaffen, das eine Steuereinheit zum Steuern der Ausgangsleistung je nach Belastung aufweist.A Another object of the present invention is to provide a combined To provide a drive unit, which has a control unit for controlling the Output power depending on the load.
Um diese Aufgaben zu erfüllen, weist die vorliegende Erfindung eine Brennstoffzelle, eine Steuereinheit, eine sekundäre Stromquelle und eine Antriebseinheit auf. Die Steuereinheit weist weiterhin einen Spannungs-/Stromsensor, einen Spannungs-/Stromsteuerkreis sowie einen Datenspeicher auf. Die Brennstoffzelle, die sekundäre Stromquelle und die Antriebseinheit sind jeweils mit der Steuereinheit elektrisch verbunden. Die Antriebseinheit wird von durch die Brennstoffzelle und der sekundären Stromquelle erzeugtem Strom getrieben, wobei weitere elektrische Vorrichtungen ebenfalls von diesen gespeist werden. Die Brennstoffzelle liefert einen maximalen Ausgangsstrom. Überschreitet dieser einen abgenommenen Laststrom, so versorgt die Brennstoffzelle allein die Last und lädt zugleich die sekundäre Stromquelle auf. Falls der Laststrom den Ausgangsstrom der Brennstoffzelle überschreitet, so wird automatisch die sekundäre Stromquelle zugeschaltet.Around to fulfill these tasks the present invention comprises a fuel cell, a control unit, a secondary one Power source and a drive unit. The control unit points a voltage / current sensor, a voltage / current control circuit and a data store. The fuel cell, the secondary power source and the drive unit are each electrically connected to the control unit connected. The drive unit is powered by the fuel cell and the secondary power source generated electricity, with other electrical devices also be fed by these. The fuel cell delivers a maximum output current. exceeds this one removed load current, so supplies the fuel cell alone the load and loads at the same time the secondary Power source on. If the load current exceeds the output current of the fuel cell, so automatically becomes the secondary one Power source switched on.
