Abstract

The invention relates to an electric running connection for a starter (4) for starting an internal combustion engine, comprising a series connection (1) consisting of a battery (2) and a capacitor (3). The starter (4) can be included in the series connection (1) in such a way that the voltage at the terminals (9) of the starter (4) represents the sum of the voltage at the battery (2) and the voltage at the capacitor (3). As a result of the series connection (1), the capacitor (3) is no longer supplied with the total starter voltage, thus enabling smaller, more compact capacitor modules to be used.

A capacitor module consisting of several double-layer capacitors is used as the capacitor.

Increased operating voltages for starters have the advantage that the cold start properties of the internal combustion engines operated with them can be improved as a result of the higher breakaway torque and also the pollutant emissions.
Die bekannten Betriebsschaltungen haben allerdings den Nachteil, daß die Batterie und der Kondensator zueinander parallel geschaltet sind. Dies bedeutet, daß die ganze für den Be- trieb des Anlassers vorgesehene Spannung am Kondensator anliegt. Der Kondensator beziehungsweise das als Kondensator verwendete Kondensatormodul aus elektrochemischen Doppel- schicht-Kondensatoren muß also für eine relativ hohe Spannung ausgelegt sein. Da die üblicherweise als Doppelschicht- Kondensatoren verwendeten Bauelemente eine relativ geringe Zellenspannung von nur 2,3 V aufweisen, bedeutet dies ein ho- hes Bauvolumen für das in der bekannten Betriebsschaltung verwendete Kondensatormodul . Desweiteren ist aufgrund der Vielzahl von Einzelkondensatoren auch das Gewicht des Kondensatormoduls in unerwünschter Weise erhöht.However, the known operating circuits have the disadvantage that the battery and the capacitor are connected in parallel to one another. This means that the entire voltage provided for the operation of the starter is applied to the capacitor. The capacitor or the capacitor module used as a capacitor made of electrochemical double Layer capacitors must therefore be designed for a relatively high voltage. Since the components usually used as double-layer capacitors have a relatively low cell voltage of only 2.3 V, this means a high volume for the capacitor module used in the known operating circuit. Furthermore, the weight of the capacitor module is undesirably increased due to the large number of individual capacitors.
Ziel der vorliegenden Erfindung ist es daher, eine Betriebsschaltung für einen Anlasser bereitzustellen, die ein Anliegen der vollen für den Betrieb des Anlassers vorgesehenen Spannung am Kondensator vermeidet .The aim of the present invention is therefore to provide an operating circuit for a starter which avoids the application of the full voltage intended for the operation of the starter to the capacitor.
Dieses Ziel wird erfindungsgemäß durch eine elektrische Betriebsschaltung für einen Anlasser nach Patentanspruch 1 erreicht. Vorteilhafte Ausgestaltungen der Erfindung sind den weiteren Ansprüchen zu entnehmen.This object is achieved according to the invention by an electrical operating circuit for a starter. Advantageous embodiments of the invention can be found in the further claims.
Die Erfindung gibt eine elektrische Betriebsschaltung für einen Anlasser an, der zum Start eines Verbrennungsmotors geeignet ist. Sie umfaßt eine Reihenschaltung aus einer Batterie und einem Kondensator. Der Anlasser ist so an die Reihenschaltung anschließbar, daß die an den Anschlüssen des Anlas- sers anliegende Spannung die Summe aus der an der Batterie anliegenden Spannung und der am Kondensator anliegenden Spannung ist.The invention provides an electrical operating circuit for a starter which is suitable for starting an internal combustion engine. It comprises a series connection of a battery and a capacitor. The starter can be connected to the series connection in such a way that the voltage applied to the connections of the starter is the sum of the voltage applied to the battery and the voltage applied to the capacitor.
Diese Betriebsschaltung hat den Vorteil, daß der Kondensator nicht für die volle an den Anschlüssen des Anlassers anliegende Spannung ausgelegt sein muß, da die an den Anschlüssen des Anlassers anliegende Spannung auch die an der Batterie anliegende Spannung enthält. Somit kann gemäß der Erfindung der Kondensator ein für eine kleinere als der am Anlasser an- liegenden Spannung ausgelegtes Bauelement sein. Insbesondere ist es von Vorteil, wenn der Kondensator ein Kondensatormodul ist, das einen oder mehrere elektrochemische DoppelSchichtkondensatoren umfaßt. Daraus ergibt sich der Vorteil, daß das Kondensatormodul durch die reduzierte Nenn- Spannung aus weniger Doppelschichtkondensatoren zusammengesetzt sein kann, wodurch das Kondensatormodul kleiner, leichter und auch billiger zu realisieren ist. Als Kondensatormodul kommen beispielsweise Produkte der Firma Epcos AG mit den Produktbezeichnungen B48700, B48710 oder auch B49300 in Be- tracht . Diese Kondensatormodule zeichnen sich alle durch eine hohe Lebensdauer, hohe Kapazität und niedrigen Innenwiderstand aus .This operating circuit has the advantage that the capacitor does not have to be designed for the full voltage present at the connections of the starter, since the voltage present at the connections of the starter also contains the voltage present at the battery. Thus, according to the invention, the capacitor can be a component designed for a voltage lower than that applied to the starter. In particular, it is advantageous if the capacitor is a capacitor module that comprises one or more electrochemical double-layer capacitors. This has the advantage that the capacitor module can be composed of fewer double-layer capacitors due to the reduced nominal voltage, as a result of which the capacitor module is smaller, lighter and also less expensive to implement. Products from Epcos AG with the product names B48700, B48710 or B49300 can be considered as a capacitor module. These capacitor modules are all characterized by a long service life, high capacity and low internal resistance.
Es ist für die Erfindung besonders vorteilhaft, einen Konden- sator mit einer Kapazität > 10 F zu verwenden. Ein solcherIt is particularly advantageous for the invention to use a capacitor with a capacitance> 10 F. Such a

Desweiteren ist es für die Erfindung vorteilhaft, wenn derFurthermore, it is advantageous for the invention if the
Kondensator einen Innenwiderstand < 50 mΩ aufweist. In diesem Fall kann der Kondensator in sehr kurzer Zeit entladen werden, wodurch er für den Betrieb eines Anlassers, wo kurzzeitig eine große Menge elektrischer Energie bereitgestellt wer- den muß, sehr gut geeignet ist.Capacitor has an internal resistance <50 mΩ. In this case, the capacitor can be discharged in a very short time, which makes it very suitable for the operation of a starter, where a large amount of electrical energy has to be provided for a short time.
Eine vorteilhafte Ausführungsform der Erfindung umfaßt ein Mittel zum Aufladen des Kondensators mit Hilfe der an der Batterie anliegenden Spannung. Ein Aufladen des Kondensators ist mit einer solchen Anordnung auch bei Stillstand des Verbrennungsmotors, wenn also kein Generator in Betrieb ist, möglich.An advantageous embodiment of the invention comprises a means for charging the capacitor with the aid of the voltage applied to the battery. With such an arrangement, the capacitor can be charged even when the internal combustion engine is at a standstill, that is to say when no generator is in operation.
Das Mittel zum Aufladen des Kondensators kann beispielsweise ein Hochsetzsteller sein, der die Gleichspannung der Batterie in eine höhere Gleichspannung umwandelt. Mit Hilfe eines solchen Hochsetzstellers ist ein einfaches Aufladen des Konden- sators als Element einer Reihenschaltung mit der Batterie möglich. So kann beispielsweise der Kondensator einfach mit der Differenz aus der vom Hochsetzsteller vergrößerten Gleichspannung und der von der Batterie gelieferten Gleich- Spannung aufgeladen werden, indem der Ausgang des Hochsetz- stellers an die Reihenschaltung aus Kondensator und Batterie angeschlossen wird.The means for charging the capacitor can be, for example, a step-up converter, which converts the DC voltage of the battery into a higher DC voltage. With the help of such a step-up converter, it is easy to charge the condenser sators possible as an element of a series connection with the battery. For example, the capacitor can simply be charged with the difference between the DC voltage increased by the step-up converter and the DC voltage supplied by the battery, by connecting the output of the step-up converter to the series connection of capacitor and battery.
In einer weiteren vorteilhaften Ausführungsform der Erfindung ist das Mittel zum Aufladen des Kondensators ein DC-In a further advantageous embodiment of the invention, the means for charging the capacitor is a DC
Transformator, der einen Hochsetzsteller und einen Tiefsetz- steller umfaßt und der an einem Generator anschließbar ist. Eine solche Betriebsschaltung hat den Vorteil, daß der DC- Transformator zwei verschiedene Funktionen in einem Bauteil integriert, wodurch die Betriebsschaltung an Komplexität abnimmt. Durch das Anschließen eines Generators an den DC- Transformator beziehungsweise an den als Tiefsetzsteiler wirkenden Teil des DC-Transformators kann mit Hilfe eines Generators, der 42 V Gleichspannung liefert, die Batterie aufge- laden werden. Dazu wird die vom Generator gelieferte Spannung mit Hilfe des Tiefsetzstellers auf eine für das Aufladen der Batterie geeignete Spannung, beispielsweise 14 V, verringert.Transformer which comprises a step-up converter and a step-down converter and which can be connected to a generator. Such an operating circuit has the advantage that the DC transformer integrates two different functions in one component, which reduces the complexity of the operating circuit. By connecting a generator to the DC transformer or to the part of the DC transformer that acts as a step-down divider, the battery can be charged with the help of a generator that supplies 42 V DC. For this purpose, the voltage supplied by the generator is reduced to a voltage suitable for charging the battery, for example 14 V, using the step-down converter.
Desweiteren ist es vorteilhaft, wenn parallel zum Kondensator eine Diode geschaltet ist. Eine solche Diode kann ein unbeabsichtigtes völliges Entladen des Kondensators, beispielsweise über die Batterie und den Anlasser, verhindern. Ab einer Mindestspannung am Kondensator kann eine solche Diode als Kurzschluß wirken und das Aufbauen einer den Kondensator umpolen- den Spannung verhindern. Dies ist insbesondere von Bedeutung, wenn als Kondensator ein Kondensatormodul aus elektrochemischen DoppelSchichtkondensatoren benutzt wird, dessen Nennspannung kleiner als die Batteriespannung ist.Furthermore, it is advantageous if a diode is connected in parallel with the capacitor. Such a diode can prevent the capacitor from being inadvertently completely discharged, for example via the battery and the starter. From a minimum voltage on the capacitor, such a diode can act as a short circuit and prevent the build-up of a voltage reversing the polarity of the capacitor. This is particularly important if a capacitor module made of electrochemical double-layer capacitors is used as the capacitor, the nominal voltage of which is lower than the battery voltage.
Desweiteren ist es vorteilhaft, wenn die Nennspannung des Kondensators größer ist als die Nennspannung der Batterie. Dadurch lassen sich besonders hohe Betriebsspannungen für den Anlasser erzeugen. Beispielsweise kann mit Hilfe einer Batterie mit einer Nennspannung von 12 V und einem Kondensator mit einer Nennspannung von 28 V eine Spannung von 40 V an den Anschlüssen des Anlassers erzeugt werden. Dadurch kann ein besonders hohes Losbrechmoment und eine geringe Schadstoffemission erzielt werden.Furthermore, it is advantageous if the nominal voltage of the capacitor is greater than the nominal voltage of the battery. This allows particularly high operating voltages for the Generate starter. For example, with the help of a battery with a nominal voltage of 12 V and a capacitor with a nominal voltage of 28 V, a voltage of 40 V can be generated at the connections of the starter. This enables a particularly high breakaway torque and low pollutant emissions to be achieved.

Bei dem Anlasser 4 handelt es sich um einen Elektromotor.FIG. 1 shows an electrical operating circuit for a starter 4 for starting an internal combustion engine, which comprises a series circuit 1 comprising a battery 2 and a capacitor 3.

Die Polung des Kondensators 3 ist so gewählt, daß die Spannung der Reihenschaltung 1 größer ist als die Spannung der Batterie 2. In dem in Figur 2 gewählten Beispiel läge also an der Reihenschaltung 1 von Batterie 2 und Konden- sator 3 eine Spannung von 19 V an.FIG. 2 shows a further operating circuit according to the invention, the reference symbols from FIG. 1 having identical meaning.

A capacitor 3, which can be a capacitor module, is connected in series. For example, a capacitor module with a nominal voltage of 7 V comes into consideration. B. is available from Epcos AG and which is composed of three electrochemical double-layer capacitors with a capacity of 2700 F. The polarity of the capacitor 3 is selected so that the voltage of the series circuit 1 is greater than the voltage of the battery 2. In the example selected in FIG. 2, a voltage of 19 V would therefore be at the series circuit 1 of the battery 2 and the capacitor 3 on.
Mit der Batterie 2 ist ein Hochsetzsteller 5 verbunden, wobei an dem Eingang 12 die Batteriespannung anliegt. An dessen dem Erdanschluß gegenüberliegenden Ausgang 13 liegt eine hochge- setzte Spannung an, die beispielsweise eine Gleichspannung von 20 V sein kann. Der Hochsetzsteller 5 ist dem Fachmann auch bekannt unter dem Namen "Unidirektionaler DC-Trafo" . Die am Ausgang 13 des Hochsetzstellers 5 anliegende Spannung wird an den Pluspol des Kondensators 3 geführt, wodurch diese Spannung an der Reihenschaltung 1 aus Batterie 2 und Kondensator 3 anliegt. Somit kann der Kondensator 3 mit der Differenz aus der am Ausgang 13 des Hochsetzstellers 5 anliegenden Spannung und der Batteriespannung aufgeladen werden.A step-up converter 5 is connected to the battery 2, the battery voltage being present at the input 12. At its output 13 opposite the ground connection there is a boosted voltage, which can be a DC voltage of 20 V, for example. The step-up converter 5 is also known to the person skilled in the art under the name "unidirectional DC transformer". The voltage present at the output 13 of the step-up converter 5 is fed to the positive pole of the capacitor 3, as a result of which this voltage is present at the series circuit 1 comprising the battery 2 and the capacitor 3. The capacitor 3 can thus be charged with the difference between the voltage present at the output 13 of the step-up converter 5 and the battery voltage.
Der Pluspol des Kondensators 3 ist mit einem Anschluß 9 des Anlassers verbunden. Ein weiterer Anschluß des Anlassers ist mit der Masse verbunden. Ein Mittelabgriff zwischen dem Kondensator 3 und der Batterie 2 ist mit einem 14V-Netzanschluß verbunden. Somit kann also bei der erfindungsgemäßen Be- triebsschaltung ein gewöhnliches Kfz-Bordnetz und der Anlasser betrieben werden.The positive pole of the capacitor 3 is connected to a terminal 9 of the starter. Another connection of the starter is connected to the ground. A center tap between the capacitor 3 and the battery 2 is connected to a 14 V mains connection. Thus, in the operating circuit according to the invention, an ordinary vehicle electrical system and the starter can be operated.
Das Kondensatormodul kann aus drei Doppelschichtkondensatoren der Firma Epcos AG mit der Bezeichnung B49300 zusammengesetzt sein. Jeder dieser Doppelschichtkondensatoren hat eine Kapazität von 2700 F, eine Zellenspannung von 2,3 V und ein Volumen von 61 x 61 x 156 mm3. Parallel zum Kondensator 3 ist eine Diode 8 geschaltet, die so gepolt ist, daß ein Umladen des Kondensators 3 verhindert wird. Ein solches Umladen kann beispielsweise durch die Bat- terie über den an dem Anschluß 9 angeschlossenen Anlasser passieren. Bei einem Absinken der über dem Kondensator 3 anliegenden (positiven) Spannung unter 1 V wird die Diode 8 leitend und verhindert den Aufbau einer der Nennspannung des Kondensators 3 entgegengesetzten Spannung über dem Kondensa- tor 3.The capacitor module can be composed of three double-layer capacitors from Epcos AG with the designation B49300. Each of these double layer capacitors has a capacitance of 2700 F, a cell voltage of 2.3 V and a volume of 61 x 61 x 156 mm 3 . A diode 8 is connected in parallel to the capacitor 3 and is polarized in such a way that the capacitor 3 is prevented from being recharged. Such recharging can take place, for example, through the battery via the starter connected to connection 9. If the (positive) voltage across the capacitor 3 drops below 1 V, the diode 8 becomes conductive and prevents the build-up of a voltage across the capacitor 3 opposite the nominal voltage of the capacitor 3.
Der Mittelabgriff zwischen der Batterie 2 und dem Kondensator 3 ist mit einem Generator 7 verbunden, der beispielsweise von einem Verbrennungsmotor angetrieben wird und der die Batterie 2 auflädt.The center tap between the battery 2 and the capacitor 3 is connected to a generator 7 which is driven, for example, by an internal combustion engine and which charges the battery 2.
Figur 3 zeigt eine weitere Ausführungsform der Erfindung, wobei gleiche Bezugszeichen dieselbe Bedeutung wie in Figur 2 haben. Die gemäß Figur 3 gezeigte Batterie 2 kann beispiels- weise ein Bleiakkumulator mit einer Nennspannung von 12 V und einer Kapazität von 45 Ah sein. Der Kondensator 3 kann beispielsweise ein Kondensatormodul mit einer Nennspannung von 28 V sein. Man erhält ein solches Kondensatormodul beispielsweise durch Reihenschaltung von zwölf Doppelschichtkondensa- toren mit einer Kapazität von 1200 F. Ein solcher Doppelschichtkondensatoren ist unter der Produktbezeichnung B49300 bei der Firma Epcos AG erhältlich. Es hat eine Kapazität von 1200 F, eine Zellenspannung von 2,3 V und ein Volumen von 61 x 33 x 155 mm3.FIG. 3 shows a further embodiment of the invention, the same reference symbols having the same meaning as in FIG. 2. The battery 2 shown in FIG. 3 can be, for example, a lead accumulator with a nominal voltage of 12 V and a capacity of 45 Ah. The capacitor 3 can be, for example, a capacitor module with a nominal voltage of 28 V. Such a capacitor module is obtained, for example, by connecting twelve double-layer capacitors with a capacitance of 1200 F in series. Such a double-layer capacitor is available under the product name B49300 from Epcos AG. It has a capacity of 1200 F, a cell voltage of 2.3 V and a volume of 61 x 33 x 155 mm 3 .
Bei dem Aufbau gemäß Figur 3 kann auf eine Diode zum Schutz des Kondensators 3 gegen Umpolen verzichtet werden, da die Nennspannung des Kondensators 3 die Nennspannung der Batterie 2 übersteigt, wodurch der Kondensator 3 durch die Batterie 2 nicht umgeladen werden kann. Der Mittelabgri f zwischen der Batterie 2 und dem Kondensator 3 ist mit einem 14V-Netzanschluß 10 verbunden. Damit kann also ein gewöhnliches Kfz-Bordnetz betrieben werden.In the construction according to FIG. 3, a diode for protecting the capacitor 3 against polarity reversal can be dispensed with, since the nominal voltage of the capacitor 3 exceeds the nominal voltage of the battery 2, as a result of which the capacitor 3 cannot be recharged by the battery 2. The Mittelabgri f between the battery 2 and the capacitor 3 is one 14V power connector 10 connected. This means that a normal vehicle electrical system can be operated.
Ferner ist der Mittelabgriff zwischen der Batterie 2 und dem Kondensator 3 mit einem DC-Transformator 6 verbunden, der einerseits die Spannung der Batterie 2 auf einen für das Aufladen des Kondensators 3 geeigneten Wert, zum Beispiel 42 V, umwandelt. Wie schon in Figur 2 diskutiert, liegt von dem Hochsetzsteller die erzeugte Spannung an der Reihenschaltung 1 aus Batterie 2 und Kondensator 3 an, wodurch der Kondensator 3 mit der Differenz aus der Spannung am Ausgang 13 des Hochsetzstellers und der Spannung der Batterie 2 aufgeladen wird.Furthermore, the center tap between the battery 2 and the capacitor 3 is connected to a DC transformer 6, which on the one hand converts the voltage of the battery 2 to a value suitable for charging the capacitor 3, for example 42 V. As already discussed in FIG. 2, the voltage generated by the boost converter is applied to the series circuit 1 comprising battery 2 and capacitor 3, as a result of which capacitor 3 is charged with the difference between the voltage at output 13 of the boost converter and the voltage of battery 2.
Der in Figur 3 dargestellte DC-Transformator ist dem Fachmann auch bekannt unter dem Namen "Bidirektionaler DC- Transformator" oder auch "Boost-/Buckkonverter" . Er umfaßt neben dem Hochsetzsteller auch einen Tiefsetzsteiler, dessen Eingang am Ausgang 13 des Hochsetzstellers, also an dem mit 42 V bezeichneten Anschluß liegt. Der Tiefsetzsteiler ist dazu geeignet, die von einem Kurbelwellenstartgenerator, welcher einen Anlasser 4 und einen Generator 7 in einem Gerät umfaßt, gelieferte Spannung in eine am Eingang des Hochsetzstellers (entspricht dem Ausgang 13) anliegende, zum Aufladen der Batterie geeigneten Spannung von beispielsweise 14 V umzuwandeln. Der Kurbelwellenstartgenerator liefert gewöhnlich eine Spannung von 42 V. Der in dem Kurbelwellenstartgenerator integrierte Anlasser 4 ist mit der Reihenschaltung 1 aus Batterie 2 und Kondensator 3 gemäß der Erfindung verbunden.The DC transformer shown in FIG. 3 is also known to the person skilled in the art under the name “bidirectional DC transformer” or also “boost / buck converter”. In addition to the step-up converter, it also includes a step-down divider, the input of which lies at the output 13 of the step-up converter, that is to say at the connection labeled 42 V. The step-down divider is suitable for converting the voltage supplied by a crankshaft start generator, which comprises a starter 4 and a generator 7 in one device, into a voltage of, for example, 14 V applied to the input of the step-up converter (corresponds to output 13) and suitable for charging the battery convert. The crankshaft start generator usually supplies a voltage of 42 V. The starter 4 integrated in the crankshaft start generator is connected to the series connection 1 of battery 2 and capacitor 3 according to the invention.
Der Pluspol des Kondensators 2 ist ferner mit einem 42V- Netzanschluß 11 verbunden, wodurch ein neuartiges Kfz- Bordnetz mit erhöhter Netzspannung mit Hilfe der erfindungsgemäßen Betriebsschaltung betrieben werden kann. Ein neuartiges Bordnetz mit erhöhter Spannung eignet sich insbesondere für den Betrieb von elektronischen Geräten in einem Kfz, die eine erhöhte elektrische Leistung benötigen. Die Erfindung beschränkt sich nicht auf die dargestellten Ausführungsbeispiele, sondern wird in ihrer allgemeinsten Form durch Patentanspruch 1 definiert . The positive pole of the capacitor 2 is also connected to a 42 V mains connection 11, as a result of which a novel motor vehicle electrical system with an increased mains voltage can be operated using the operating circuit according to the invention. A new type of electrical system with increased voltage is particularly suitable for the operation of electronic devices in a motor vehicle that require increased electrical power. The invention is not limited to the exemplary embodiments shown, but is defined in its most general form by patent claim 1.
