Abstract

Die Erfindung betrifft ein Elektorfahrzeug mit Batterieantrieb und serieller Hilfsgeneratoreinheit (APU), wobei diese geräuscharm gekapselt innerhalb der Fahrzeugkarosserie eingebaut ist, deren Ladeleistung nur einen Teil der vollen Batterieleistung beträgt, deren Generator (3) eine Erregung aus Permantentmagneten aufweist, dessen Verbrennungsmotor auf einen bestimmten Lastpunkt ausgelegt und mit einem Abgasfilter versehen ist, und welches eine Steuereinheit (5) für die Batterieladung entweder aus der APU, dem Netz oder einem anderen Stromerzeuger umfasst.The invention relates to an electric vehicle with battery drive and serial auxiliary generator unit (APU), which is installed with low noise encapsulated within the vehicle body, the charging power is only part of the full battery power whose generator (3) has a permanent magnet excitation whose combustion engine to a certain Load point is designed and provided with an exhaust filter, and which comprises a control unit (5) for the battery charge either from the APU, the grid or other power generator.

Description

Die Erfindung betrifft ein Elektrofahrzeug mit Batterieantrieb und serieller Hilfsgeneratoreinheit (APU).The The invention relates to an electric vehicle with battery drive and serial Auxiliary Generator Unit (APU).

Ein derartiges elektrisch angetriebenes Kraftfahrzeug ist in der europäischen Patentschrift 0 003 888 B1 beschrieben. Demnach besitzt das bekannte Elektrofahrzeug einen Elektromotor für den Antrieb des Kraftfahrzeugs über ein Übertragungssystem mit einem Batteriepaket, welches an eine Hilfsgeneratoreinheit anschließbar ist, die eine Brennkraftmaschine enthält. Eine derartige Hilfsgeneratoreinheit dient zum Aufladen des Batteriepakets und damit der Vergrößerung des Aktionsradius des Fahrzeugs. Eine Steuereinheit kann vom Fahrer des Fahrzeugs so betätigt werden, dass die Leistung des elektrischen Antriebsmotors gesteuert werden kann.Such an electrically driven motor vehicle is in the European Patent 0 003 888 B1 described. Accordingly, the known electric vehicle has an electric motor for driving the motor vehicle via a transmission system with a battery pack, which is connectable to an auxiliary generator unit containing an internal combustion engine. Such an auxiliary generator unit serves to charge the battery pack and thus to increase the operating radius of the vehicle. A control unit can be operated by the driver of the vehicle so that the power of the electric drive motor can be controlled.

Die Unterbringung des Batteriepakets und der Hilfsgeneratoreinheit bereitet keine räumlichen Schwierigkeiten, da es sich bei dem Elektrofahrzeug um einen Bus handelt, der flurseitig genügend Stauraum bietet.The Accomodation of the battery pack and the auxiliary generator unit prepares no spatial difficulties, since it is the electric vehicle to a bus, the flurseitig offers enough storage space.

Da ein derartiger Stauraum bei kleineren Fahrzeugen fehlt, sehen andere bekannte Lösungen vor, die Energieversorgung, umfassend ein Batteriepaket, einen Generator, eine Verbrennungskraftmaschine und einen Stromwandler außerhalb der Fahrzeugkarosserie unterzubringen, beispielsweise auf dem Fahrzeugdach ( DE 19832873 A1 ) oder auf einem speziellen Fahrzeuganhänger ( DE 19509625 A1 ).Since such storage space is lacking in smaller vehicles, other known solutions provide for accommodating the power supply comprising a battery pack, a generator, an internal combustion engine and a current transformer outside the vehicle body, for example on the vehicle roof (FIG.

Demgegenüber besteht die Aufgabe der vorliegenden Erfindung darin, das Batteriepaket bei einem Elektrofahrzeug durch eine Hilfsgeneratoreinheit von besonders geringer Baugröße nachzuladen, welche zusätzlich zum Batteriepaket auch in einem PKW Platz findet und welche im übrigen alle Anforderungen an ein emissionsarmes Fahrzeug erfüllt.In contrast, the object of the present invention is the battery pack in an electric vehicle by an auxiliary generator unit of particular recharge small size, which in addition to the battery pack also finds place in a car and which otherwise meets all requirements for a low-emission vehicle.

Erfindungsgemäß ist an einem Fahrzeug, welches dieser Aufgabe gerecht wird, eine Hilfsgeneratoreinheit (APU) vorgesehen, welche geräuscharm gekapselt innerhalb der Fahrzeugkarosserie eingebaut ist, deren Ladeleistung nur einen Teil der vollen Batterieleistung beträgt, deren Generator eine Erregung aus Permanentmagneten aufweist, dessen Motor auf einen bestimmten Lastpunkt ausgelegt und mit einem Abgasfilter versehen ist, und welches eine Steuereinheit für die Batterieladung entweder aus der APU, dem Netz oder einem anderen Stromerzeuger umfasst.According to the invention on a vehicle which does this task, an auxiliary generator unit (APU), which encapsulated quietly within the vehicle body is installed, the charging power only one Part of the full battery power is its generator has an excitation of permanent magnets whose motor on a designed specific load point and provided with an exhaust filter is, and which is a control unit for battery charging either from the APU, the grid or another power generator includes.

Eine derartige Hilfsgeneratoreinheit ermöglicht eine sehr gedrängte Bauweise, denn der die Permanentmagneten tragende Rotor des Generators kann gleichzeitig die Funktion des Schwungrads des Verbrennungsmotors übernehmen, d. h. es bietet sich ein Zusammenbau aus Motor und Generator in einem gemeinsamen Gehäuse an. Dadurch, dass der Motor auf einen bestimmten Lastpunkt, der zumeist geringfügig unter dem Volllastpunkt liegen wird, ausgelegt ist, läuft er mit entsprechend hohem Wirkungsgrad bei relativ kleiner Leistung und Baugröße. Durch die Kapselung der Hilfsgeneratoreinheit besteht die Möglichkeit, diese auch in einem PKW sowohl unter der Motorhaube, im Heck oder auch in der Fahrzeugmitte einzubauen, weil durch die Kapselung Motorgeräusche weitgehend eliminiert werden. Außerdem ist zu berücksichtigen, dass der Motor nicht ständig läuft, sondern zumeist während das Fahrzeug parkt. Im Rahmen der Erfindung ist vollkommen ausreichend, dass die Ladeleistung der APU nur einen Teil der vollen Batterieleistung beträgt entsprechend der seriellen Anordnung der APU, welche nicht als Teil eines Hybridantriebs zu verstehen ist. Deren Zielsetzung ist allein das Aufladen des Batteriepakets, wofür besonders die Stillstandszeiten des Elektrofahrzeugs benutzt werden. Die APU ermöglicht somit ein Auskommen mit einem kleineren Batteriesatz bei gleichzeitiger Vergrößerung des Aktionsradius des Fahrzeugs. Es versteht sich von selbst, dass das Elektrofahrzeug über eine Steuereinheit das Wiederaufladen des Batteriepakets ermöglicht, wenn das Fahrzeug außer Betrieb ist, z. B. während es in der Garage abgestellt ist. Dort wird die Batterieladung nicht über die Hilfsgeneratoreinheit gewährleistet, sondern durch Energieeinspeisung aus dem öffentlichen Netz oder durch einen anderen Stromerzeuger, beispielsweise einer Solarenergiequelle oder einer vorhandenen Blockheizkraftwerkseinheit.A Such auxiliary generator unit allows a very crowded Construction, because of the permanent magnets bearing rotor of the generator can at the same time take over the function of the flywheel of the internal combustion engine, d. H. It offers an assembly of engine and generator in one common housing. Because of the engine on one certain load point, which is usually slightly below the Full load point is lying, is designed, he runs with according to high efficiency at relatively low power and Size. By the encapsulation of the auxiliary generator unit There is also the possibility of this in a car both under the bonnet, in the rear or in the middle of the vehicle, because the encapsulation largely eliminates engine noise become. It should also be noted that the engine does not run constantly, but mostly while the vehicle is parked. Within the scope of the invention perfectly adequate that the charging power of the APU only one Part of the full battery power is equal to the serial arrangement of the APU, which is not part of a hybrid drive to understand. Their goal is solely to charge the Battery packs, especially for the downtime of Electric vehicle used. The APU thus allows a livelihood with a smaller battery pack at the same time Increase the radius of action of the vehicle. It goes without saying that the electric vehicle over a control unit allows the recharging of the battery pack, when the vehicle is out of service, z. During it is parked in the garage. There, the battery charge is not over ensures the auxiliary generator unit, but by Energy supply from the public network or through another generator, such as a solar energy source or an existing cogeneration unit.

In einer bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass die Ladeleistung der APU 30–60% der maximalen Batterieleistung beträgt. Für eine sparsame PKW-Anwendung mag ein Leistungsbereich des PM-Generators von 1 bis 5 kW genügen. Bei einem Mittelklassefahrzeug kann ein größerer Leistungsbereich z. B. von 3 bis 15 kW Ladeleistung in Frage kommen. Je größer die relative Ladeleistung, desto geringer kann die maximale Batterieleistung gewählt werden. Dabei ist bei der Bewertung von Einsparungsmöglichkeiten zu berücksichtigen, dass die Kosten je Kilowattstunde Batterieleistung nach derzeitigem Stand der Technik noch relativ hoch sind, z. B. für Lithium-Ionen-Batterien ca. EUR 1000/kWh betragen.In a preferred embodiment of the invention is provided that the charging power of the APU 30-60% of the maximum battery power is. For a fuel-efficient car application like a performance range of the PM generator from 1 to 5 kW are sufficient. In a middle class vehicle can a larger power range z. From 3 to 15 kW charging capacity come into question. The bigger the relative charging power, the lower the maximum battery power to get voted. It is in the evaluation of savings to take into account that the cost per kilowatt-hour of battery power According to the current state of the art are still relatively high, z. B. for lithium-ion batteries approx. EUR 1000 / kWh.

Ein geeigneter Verbrennungsmotor ist wegen seiner kleinen Bauweise und der Möglichkeit des Einbaus mit vertikaler Welle ein Kleindieselmotor, bevorzugt als Einzylindermotor, oder ein Zweizylinder-V-Motor.One suitable internal combustion engine is because of its small construction and the possibility of installation with vertical shaft a small diesel engine, preferably as a single-cylinder engine, or a two-cylinder V-engine.

Im Interesse einer möglichst hochwertigen Emissionsfreiheit ist es bei derartigen Dieselmotoren zweckmäßig, kleine Partikelfilter im Abgasstrang zu verwenden, welche ein geschlossenes Sammelsystem bilden, so dass sie ein Abbrennen der gefangenen Partikel bei entsprechend hoher Abgastemperatur ermöglichen. Dabei kann erfindungsgemäß die Abgastemperatur vor dem Partikelfilter mittels elektrischer Glühwendeln oder dergleichen Wicklung als sog. Dummyload auf Abbrandtemperaturen von wenigstens 300°C und wo nötig bis zu 600°C angehoben werden.In the interest of the highest possible emission freedom, it is in such diesel engines appropriate to use small particulate filter in the exhaust system, which form a closed collection system so that they allow burning of the trapped particles at a correspondingly high exhaust gas temperature. In this case, according to the invention, the exhaust gas temperature upstream of the particulate filter can be raised by means of electric filaments or the like winding as a so-called dummy load to combustion temperatures of at least 300 ° C. and, where necessary, up to 600 ° C.

Die APU kann auf geeignete Weise gekühlt werden, z. B. mittels Luft-, Wasser- oder Ölkühlung, wobei letztere im Interesse einer besonders kompakten Bauweise vorzuziehen ist.The APU can be cooled in a suitable manner, for. B. by means Air, water or oil cooling, the latter in the interest of a particularly compact design is preferable.

Da batteriebetriebene Fahrzeuge schwer zu heizen sind, kann in weiterer Ausgestaltung der Erfindung der Dieselmotor mit einem Wärmetauscher für eine Fahrzeugheizeinrichtung versehen sein.There Battery-powered vehicles are difficult to heat in further Embodiment of the invention of the diesel engine with a heat exchanger be provided for a vehicle heater.

Je nach Ort der Unterbringung der APU im Inneren der Fahrzeugkarosserie kann es zweckmäßig sein, das Batteriepaket so zu positionieren, dass eine Vergleichmäßigung der Achslasten des Fahrzeugs erzielt wird. Was die Kapselung der APU betrifft, so ist darauf zu achten, dass diese durch schallschluckende Wände nicht nur umfassend eingehüllt wird, sondern dass auch die nach außen führenden Luftschächte mit schalldämmenden Werkstoffen ausgekleidet werden. Dies kann auch für die unmittelbare Fahrzeugumgebung, z. B. die Innenseite der Motorhaube oder des Kofferraumdeckels, zweckmäßig sein. Eine bei parkendem Fahrzeug laufende APU ist dann im Tageslärm akustisch praktisch nicht mehr wahrnehmbar.ever the location of the housing of the APU inside the vehicle body It may be appropriate, the battery pack so to position that equalization the axle loads of the vehicle is achieved. As for the encapsulation of As far as APU is concerned, it is important to ensure that these are sound-absorbing Walls are not only enveloped comprehensively, but that also the outward leading air shafts be lined with sound-absorbing materials. This can also for the immediate vehicle environment, z. B. the inside of the hood or the boot lid, be appropriate. A parked vehicle running APU is then in the daytime noise acoustically practically imperceptible.
