Stand der Technik State of the art
In zunehmenden Maße werden von der Kraftfahrzeugindustrie Kraftfahrzeuge entwickelt und/oder hergestellt, die mit einem Elektromotor angetrieben werden.Increasingly, motor vehicles are being developed and / or manufactured by the motor vehicle industry which are driven by an electric motor.
Dabei stammt die elektrische Energie für den Betrieb des Elektromotors zum Antrieb des Elektrofahrzeuges aus einer in dem Elektrofahrzeug angeordneten Batterie. Die Batterie wird dabei während des Stillstandes des Elektrofahrzeuges an einem Stromnetz aufgeladen. Das Elektrofahrzeug umfasst hierzu ein Ladegerät. Die Kapazität zum Speichern von elektrischer Energie der Batterie ist dabei beschränkt, so dass von dem Elektrofahrzeug nur Reichweiten im Bereich von ungefähr 50 km bis 200 km erreicht werden können. Zur Vergrößerung der Reichweite des Elektrofahrzeuges ist dieses mit einem sogenannten Range Extender, einer Verbrennungsmotor-Generator-Einheit, versehen. Bei längeren Fahrstrecken mit dem Elektrofahrzeug, während denen die Batterie nicht oder nicht ausreichend von einem Stromnetz aufgeladen werden kann, wird mittels der Verbrennungsmotor-Generator-Einheit die Batterie aufgeladen und/oder mittels der Verbrennungsmotor-Generator-Einheit dem Elektromotor elektrischer Strom zugeführt. Dadurch kann die mögliche Reichweite eines derartigen Elektrofahrzeuges mit einem Range Extender vergrößert werden auf Reichweiten bis ungefähr 600 km, die einer Reichweite von herkömmlichen Kraftfahrzeugen entspricht, die ausschließlich mit einem Verbrennungsmotor angetrieben werden. In this case, the electrical energy for the operation of the electric motor for driving the electric vehicle comes from a battery disposed in the electric vehicle. The battery is charged during standstill of the electric vehicle to a power grid. The electric vehicle includes a charger for this purpose. The capacity for storing electrical energy of the battery is limited, so that only ranges in the range of about 50 km to 200 km can be achieved by the electric vehicle. To increase the range of the electric vehicle this is provided with a so-called range extender, an internal combustion engine-generator unit. For longer distances with the electric vehicle, during which the battery can not or not sufficiently charged by a mains, the battery is charged by means of the internal combustion engine-generator unit and / or electric power supplied to the electric motor by means of the internal combustion engine-generator unit. As a result, the possible range of such an electric vehicle with a range extender can be increased to ranges to about 600 km, which corresponds to a range of conventional motor vehicles, which are driven exclusively by an internal combustion engine.

Die Spannung des Gleichstromes wird durch ein Steuern und/oder Regeln der Drehzahl des Generators ausgeführt. Damit ist es nicht erforderlich, mittels eines aufwendigen und teueren Pulswechselrichters die Spannung des Gleichstromes zu steuern und/oder zu regeln. Dies wird in einfacher Weise dadurch ausgeführt, dass die Drehzahl des Generators gesteuert und/oder geregelt wird, weil die von dem Generator erzeugte Spannung des Wechselstromes von der Drehzahl des Generators abhängig ist. Rectifying the alternating current into direct current, controlling and / or regulating the Voltage of the direct current, wherein the voltage of the direct current is carried out by means of controlling and / or regulating the rotational speed of the generator. The voltage of the direct current is carried out by controlling and / or regulating the rotational speed of the generator. Thus, it is not necessary to control and / or regulate the voltage of the direct current by means of a complex and expensive pulse inverter. This is done in a simple manner in that the speed of the generator is controlled and / or regulated, because the voltage of the alternating current generated by the generator is dependent on the speed of the generator.
Insbesondere wird die Spannung des Gleichstromes ausschließlich mittels Steuern und/oder Regeln der Drehzahl des Generators ausgeführt. In particular, the voltage of the direct current is carried out exclusively by means of controlling and / or regulating the rotational speed of the generator.

Der Generator ist mit dem Verbrennungsmotor mittels einer In a further embodiment, the rotational speed of the generator, in particular exclusively, is controlled and / or regulated by means of the rotational speed of the internal combustion engine. The generator is connected to the internal combustion engine by means of a
Antriebswelle verbunden. Damit hängt die Drehzahl des Generators von der Drehzahl des Verbrennungsmotors ab. In einer weiteren Ausgestaltung wird die Drehzahl des Generators dadurch gesteuert, dass mittels eines Getriebes, welches den Verbrennungsmotor und den Generator miteinander verbindet, die Drehzahl des Generators gesteuert wird unabhängig von der Drehzahl des Verbrennungsmotors. In einer ergänzenden Ausführungsform wird der Wechselstrom von einem ungesteuerten Gleichrichter in Gleichstrom umgewandelt. Drive shaft connected. Thus, the speed of the generator depends on the speed of the engine. In a further embodiment, the rotational speed of the generator is controlled by means of a transmission, which connects the internal combustion engine and the generator with each other, the rotational speed of the generator is controlled independently of the rotational speed of the internal combustion engine. In an additional embodiment, the alternating current is converted into direct current by an uncontrolled rectifier.
Erfindungsgemäße Verbrennungsmotor-Generator-Einheit als Range Extender, umfassend: einen Verbrennungsmotor, einen Generator, vorzugsweise einen Kraftstofftank, einen Gleichrichter zum Gleichrichten des von dem Generator erzeugten Wechselstromes in Gleichstrom, eine Einrichtung zur Steuerung und/oder Regelung der Spannung des von dem Gleichrichter zur Verfügung gestellten Gleichstromes, wobei der Gleichrichter ein ungesteuerter Gleichrichter ist. Die Verbrennungsmotor-Generator-Einheit umfasst damit keinen An internal combustion engine / generator unit according to the invention as a range extender, comprising: an internal combustion engine, a generator, preferably a fuel tank, a rectifier for rectifying the alternating current generated by the generator into direct current, a device for controlling and / or regulating the voltage of the rectifier for Provided direct current, wherein the rectifier is an uncontrolled rectifier. The internal combustion engine-generator unit thus includes none

Wechselstromes in Gleichstrom und/oder zur Steuerung und/oder Regelung der Spannung des Gleichstromes. Der ungesteuerte Gleichrichter ist in der AC in DC and / or for controlling and / or regulating the Voltage of direct current. The uncontrolled rectifier is in the
Anschaffung wesentlich preiswerter als ein aufwendiger und teuerer Acquisition much cheaper than a complex and expensive
Pulswechselrichter. Damit können die Kosten zur Anschaffung des Pulse inverter. Thus the costs for the purchase of the
Pulswechselrichters eingespart werden und trotzdem ist eine Steuerung oder Regelung der Spannung des Gleichstromes möglich. Pulse inverter can be saved and still a control or regulation of the voltage of the direct current is possible.

Wird von der Einrichtung die Drehzahl des Generators gesteuert und/oder geregelt, ist die Einrichtung beispielsweise ein Getriebe, mittels dem die Drehzahl des Preferably, the device is a control unit for controlling and / or regulating the rotational speed of the internal combustion engine or of the generator. If the device controls and / or regulates the rotational speed of the generator, the device is, for example, a transmission by means of which the rotational speed of the
Generators entkoppelt ist von der Drehzahl des Verbrennungsmotors. Der Verbrennungsmotor treibt somit mittels des Getriebes den Generator an und mittels des Getriebes ist die Drehzahl des Generators steuerbar und/oder regelbar. Abweichend hiervon ist die Einrichtung eine Steuerungseinheit zur Steuerung und/oder Regelung der Drehzahl des Verbrennungsmotors. Hierzu ist der Verbrennungsmotor mittels einer Antriebswelle mit dem Generator mechanisch verbunden und die Drehzahl des Generators entspricht der Drehzahl des Verbrennungsmotors oder die Drehzahl des Generators steht in einem konstanten Verhältnis zur Drehzahl des Verbrennungsmotors. Generator is decoupled from the speed of the internal combustion engine. The internal combustion engine thus drives the generator by means of the gearbox and by means of the gearbox the rotational speed of the generator can be controlled and / or regulated. Deviating from this, the device is a control unit for controlling and / or regulating the rotational speed of the internal combustion engine.

Verbrennungsmotor-Generator-Einheit 6 eingesetzt. Mittels der Combustion engine-generator unit 6 is used. By means of
Verbrennungsmotor-Generator-Einheit 6 als sogenannter Range Extender 6 wird mittels Kraftstoff aus einem Kraftstofftank 5, der durch eine Kraftstoffleitung 16 geleitet wird, mechanische Energie von einem Verbrennungsmotor 7 erzeugt, der von einem Generator 8 als permanentmagneterregte Synchronmaschine 9 in elektrische Energie umgewandelt wird. Der Verbrennungsmotor 7 ist dem Generator 8 mittels einer Antriebswelle 15 mechanisch verbunden (Fig. 1 ). Der Generator 8 erzeugt Wechselstrom, der von einem ungesteuerten Gleichrichter 1 1 in Gleichstrom umgewandelt wird. Mittels der elektrischen Energie aus dem Generator 8 wird entweder die Batterie 4 aufgeladen oder der Elektromotor 3 betrieben. Dadurch kann die Reichweite des Elektrofahrzeuges 1 wesentlich, z. B. auf Reichweiten im Bereich von ungefähr 300 km bis 600 km, erweitert werden. Die Reichweite des Elektrofahrzeuges 1 mittels elektrischer Energie aus der Batterie 4 liegt beispielsweise im Bereich von 50 km bis 150 km.

The internal combustion engine 7 is mechanically connected to the generator 8 by means of a drive shaft 15 (FIG. 1). The generator 8 generates alternating current, which is converted by an uncontrolled rectifier 1 1 in direct current. By means of the electrical energy from the generator 8, either the battery 4 is charged or the electric motor 3 is operated. As a result, the range of the electric vehicle 1 essential, z. To ranges in the range of about 300 km to 600 km. The range of the electric vehicle 1 by means of electrical energy from the battery 4 is for example in the range of 50 km to 150 km.

Zum Aufladen der Batterie 4 des Elektro- oder Hybridfahrzeuges 1 , 2 (Fig. 3) ist es erforderlich, dass die von dem Gleichrichter 1 1 zur Verfügung gestellte Spannung des Gleichstromes größer ist als die Spannung der Batterie 4. Die Spannung der Batterie 4 hängt dabei von dem Lade- oder Belastungszustand der Batterie 4 ab. Eine Steuerungseinheit 13 erhält mittels nicht dargestellter Steuerungsleitungen von dem Batteriemanagementsystem 14 einen Sollwert für die Spannung des Gleichstromes zum Aufladen der Batterie 4. Mittels dieses Sollwertes wird von der Steuerungseinheit 13 als Einrichtung 10 zur Steuerung der Spannung des Gleichstromes die Drehzahl des Verbrennungsmotors 7 gesteuert und/oder geregelt. Je höher die Drehzahl des Verbrennungsmotors 7 und damit auch des Generators 8, aufgrund der mechanischen Kopplung lediglich mittels der Antriebswelle 15, desto größer ist die Spannung des von dem Generator 8 zur Verfügung gestellten Wechselstromes. Je höher die Spannung des von dem Generator 8 zur Verfügung gestellten Wechselstromes ist, desto größer ist die Spannung des von dem Gleichrichter 1 1 zur Verfügung gestellten Gleichstromes und umgekehrt.

To charge the battery 4 of the electric or hybrid vehicle 1, 2 (FIG. 3), it is necessary for the voltage of the direct current provided by the rectifier 11 to be greater than the voltage of the battery 4. The voltage of the battery 4 hangs thereby from the charge or load condition of the battery 4. A control unit 13 receives by means of not shown control lines of the battery management system 14, a target value for the voltage of the DC for charging the battery 4. By means of this target value is controlled by the control unit 13 as means 10 for controlling the voltage of the DC current, the speed of the engine 7 and / or regulated. The higher the speed of the internal combustion engine 7 and thus also of the generator 8, due to the mechanical coupling only by means of the drive shaft 15, the greater the voltage of the alternating current provided by the generator 8 available. The higher the voltage of the alternating current provided by the generator 8, the greater the voltage of the direct current provided by the rectifier 11, and vice versa. This can only by the control and / or regulation of the speed of the engine 7 and thus also the
Generators 8 die Spannung des von dem Gleichrichter 1 1 gleichgerichteten Stromes zum Aufladen der Batterie gesteuert und/oder geregelt werden. In einem weiteren, nicht dargestellten Ausführungsbeispiel der Generator 8, the voltage of the rectifier 1 1 rectified current to charge the battery controlled and / or regulated. In a further, not shown embodiment of
Verbrennungsmotor-Generator-Einheit 6 ist der Verbrennungsmotor 7 mit dem Generator 8 mittels eines Getriebes verbunden. Mittels dieses Getriebes kann die Drehzahl des Generators 8 unabhängig von der Drehzahl des Internal combustion engine-generator unit 6, the internal combustion engine 7 is connected to the generator 8 by means of a transmission. By means of this transmission, the speed of the generator 8, regardless of the speed of the
Verbrennungsmotors 7 gesteuert und/oder geregelt werden und damit auch die Spannung des von dem Gleichrichter 1 1 zur Verfügung gestellten Gleichstromes. Die Steuerungseinheit 13 steuert mittels des nicht dargestellten Getriebes die Drehzahl des Generators 8 und damit auch die Spannung des von dem Internal combustion engine 7 controlled and / or regulated and thus also the voltage of the rectifier 1 1 provided direct current.
