Definitions

  • the invention relates to an electric vehicle with battery drive and within the vehicle body built-in auxiliary generator unit (APU), the charging power is only a part of the full battery power.
  • APU auxiliary generator unit
  • Such an electric vehicle is known from DE 102007004172 Al.
  • a motor-generator unit is provided, which serves to recharge the battery pack for the drive in the parked state of the vehicle.
  • the generator While driving, the generator is not battery charging but emergency power if the traction batteries are discharged or faulty. In this case, the generator drives directly on the electric traction drives, so that an emergency driving with limited speed is guaranteed.
  • European Patent 0 003 888 B1 describes an electrically driven motor vehicle having an electric motor for driving the motor vehicle with a battery pack which can be connected to an auxiliary generator unit which contains an internal combustion engine.
  • the auxiliary generator unit serves to charge the battery pack and thus to increase the operating radius of the vehicle.
  • the driver of the vehicle can control the power of the electric drive motor.
  • the accommodation of the battery pack and the Hilfsge- eratorü prepares no spatial difficulties, since it is the electric vehicle is a bus, the flur note provides enough storage space.
  • the object of the present invention is to recharge the battery pack in an electric vehicle by an auxiliary generator unit of particularly small size while driving, which in addition to the battery pack in a car place and which otherwise meets all requirements for a low-emission vehicle ,
  • auxiliary generator unit allows a very compact construction, because the rotor of the generator carrying the permanent magnets can at the same time transmit the function of the flywheel of the internal combustion engine. take, ie it offers an assembly of motor and generator in a common housing.
  • the encapsulation of the auxiliary generator unit makes it possible to install it in a car under the hood, in the rear or in the middle of the vehicle, because the encapsulation largely eliminates engine noise.
  • the engine is not constantly running, but mostly while the vehicle is parked.
  • the charging power of the APU is only a part of the full battery power.
  • Their task is solely the charging of the battery pack, for which especially the downtime of the electric vehicle can be used.
  • the APU thus makes it possible to make do with a smaller battery pack while increasing the range of action of the vehicle.
  • a control unit allows the electric vehicle to recharge the battery pack when the vehicle is out of service, eg while it is parked in the garage. There, the battery charge is ensured, for example, by feeding energy from the public grid or by another power generator, such as a solar energy source or an existing cogeneration unit.
  • the charging power of the APU is 30-60% of the maximum battery power.
  • a power range of the PM generator of 1 to 5 kW may suffice.
  • a larger power range for example from 3 to 15 kW charging power can be considered.
  • the larger the relative charging power the lower the maximum battery power can be selected. It should be taken into account when evaluating potential savings that the costs per kilowatt-hour of battery power according to the current state of the art are still relatively high, for example for lithium-ion batteries amount to about EUR 1000 / kWh.
  • a suitable internal combustion engine is because of its small size and the possibility of installation with a vertical shaft a small diesel engine, preferably as a single-cylinder engine, or a two-cylinder V-engine.
  • the exhaust gas temperature as a so-called winding before the particle filter by means of electrical filaments or the like.
  • Abbrandtempera- dummy load to temperatures of at least 300 0 C and are, where necessary, raised up to 600 0 C.
  • the APU can be cooled in a suitable manner, for example by means of air, water or oil cooling, the latter being preferable in the interests of a particularly compact design. Since battery-powered vehicles are difficult to heat, in a further embodiment of the invention, the diesel engine may be provided with a heat exchanger for a vehicle heater.
  • the battery pack may be appropriate to position the battery pack so that an equalization of the axle loads of the vehicle is achieved.
  • the encapsulation of the APU it should be ensured that it is not only completely enveloped by sound-absorbing walls, but also that the air ducts leading to the outside are lined with sound-absorbing materials. This can also be done for the immediate vehicle environment, e.g. the inside of the hood or the boot lid, be appropriate. An APU running when the vehicle is parked is then practically no longer perceptible in the daytime noise.
  • Fig. 1 shows the battery drive of an electric vehicle with auxiliary generator unit as a schematic diagram and Fig. 2 shows two installation options of an APU in a car.

Description

Elektrofahrzeug electric vehicle
Die Erfindung betrifft ein Elektrofahrzeug mit Batterieantrieb und innerhalb der Fahrzeugkarosserie eingebauter Hilfsgeneratoreinheit (APU) , deren Ladeleistung nur einen Teil der vollen Batterieleistung beträgt.The invention relates to an electric vehicle with battery drive and within the vehicle body built-in auxiliary generator unit (APU), the charging power is only a part of the full battery power.
Ein derartiges Elektrofahrzeug ist aus DE 102007004172 Al bekannt. Dabei ist eine Motor-Generator-Einheit vorgesehen, welche dazu dient, das Batteriepaket für den Fahrantrieb im abgestellten Zustand des Fahrzeugs nachzuladen. Während der Fahrt dient der Generator nicht der Batterieladung sondern als Notantrieb, falls die Traktionsbatterien entladen oder fehlerhaft sind. In diesem Fall treibt der Generator direkt auf die elektrischen Fahrantriebe, so dass ein Notfahrbetrieb mit begrenzter Fahrgeschwindigkeit gewährleistet ist.Such an electric vehicle is known from DE 102007004172 Al. In this case, a motor-generator unit is provided, which serves to recharge the battery pack for the drive in the parked state of the vehicle. While driving, the generator is not battery charging but emergency power if the traction batteries are discharged or faulty. In this case, the generator drives directly on the electric traction drives, so that an emergency driving with limited speed is guaranteed.
In der europäischen Patentschrift 0 003 888 Bl ist ein elektrisch angetriebenes Kraftfahrzeug mit einem Elektromotor für den Antrieb des Kraftfahrzeugs mit einem Batteriepaket beschrieben, welches an eine Hilfsgenera- toreinheit anschließbar ist, die eine Brennkraftmaschine enthält. Die Hilfsgeneratoreinheit dient zum Aufladen des Batteriepakets und damit der Vergrößerung des Aktionsradius des Fahrzeugs. Mittels einer Steuereinheit kann der Fahrer des Fahrzeugs die Leistung des elektrischen Antriebsmotors steuern. Die Unterbringung des Batteriepakets und der Hilfsgene- ratoreinheit bereitet keine räumlichen Schwierigkeiten, da es sich bei dem Elektrofahrzeug um einen Bus handelt, der flurseitig genügend Stauraum bietet.European Patent 0 003 888 B1 describes an electrically driven motor vehicle having an electric motor for driving the motor vehicle with a battery pack which can be connected to an auxiliary generator unit which contains an internal combustion engine. The auxiliary generator unit serves to charge the battery pack and thus to increase the operating radius of the vehicle. By means of a control unit, the driver of the vehicle can control the power of the electric drive motor. The accommodation of the battery pack and the Hilfsge- eratoreinheit prepares no spatial difficulties, since it is the electric vehicle is a bus, the flurseitig provides 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 Al) oder auf einem speziellen Fahrzeuganhänger (DE 19509625 Al) .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 (DE 19832873 A1) or on a special vehicle trailer (US Pat. DE 19509625 Al).
Demgegenüber besteht die Aufgabe der vorliegenden Erfindung darin, das Batteriepaket bei einem Elektrofahr- zeug durch eine Hilfsgeneratoreinheit von besonders geringer Baugröße auch während der Fahrt 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 to recharge the battery pack in an electric vehicle by an auxiliary generator unit of particularly small size while driving, which in addition to the battery pack in a car place and which otherwise meets all requirements for a low-emission vehicle ,
Diese Aufgabe wird bei einem Elektrofahrzeug der eingangs genannten Art gemäß dem Kennzeichen von Anspruch 1 gelöst.This object is achieved in an electric vehicle of the type mentioned according to the characterizing part of claim 1.
Eine derartige Hilfsgeneratoreinheit ermöglicht eine sehr gedrängte Bauweise, denn der die Permanentmagneten tragende Rotor des Generators kann gleichzeitig die Funktion des Schwungrads des Verbrennungsmotors über- nehmen, 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. Deren Aufgabe 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. Über eine Steuereinheit ermöglicht das Elektrofahrzeug das Wiederaufladen des Batteriepakets, wenn das Fahrzeug außer Betrieb ist, z.B. während es in der Garage abgestellt ist. Dort wird die Batterieladung beispielsweise durch Energieeinspeisung aus dem öffentlichen Netz oder durch einen anderen Stromerzeuger, wie einer Solarenergiequelle oder einer vorhandenen Blockheizkraftwerkseinheit, gewährleistet . Erfindungsgemäß 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.Such an auxiliary generator unit allows a very compact construction, because the rotor of the generator carrying the permanent magnets can at the same time transmit the function of the flywheel of the internal combustion engine. take, ie it offers an assembly of motor and generator in a common housing. The fact that the engine is designed for a specific load point, which will usually be slightly below the full load point, it runs with a correspondingly high efficiency at relatively low power and size. The encapsulation of the auxiliary generator unit makes it possible to install it in a car under the hood, in the rear or in the middle of the vehicle, because the encapsulation largely eliminates engine noise. In addition, it should be noted that the engine is not constantly running, but mostly while the vehicle is parked. Within the scope of the invention, it is perfectly sufficient that the charging power of the APU is only a part of the full battery power. Their task is solely the charging of the battery pack, for which especially the downtime of the electric vehicle can be used. The APU thus makes it possible to make do with a smaller battery pack while increasing the range of action of the vehicle. A control unit allows the electric vehicle to recharge the battery pack when the vehicle is out of service, eg while it is parked in the garage. There, the battery charge is ensured, for example, by feeding energy from the public grid or by another power generator, such as a solar energy source or an existing cogeneration unit. According to the invention, the charging power of the APU is 30-60% of the maximum battery power. For a fuel-efficient car application, a power range of the PM generator of 1 to 5 kW may suffice. In a mid-range vehicle, a larger power range, for example from 3 to 15 kW charging power can be considered. The larger the relative charging power, the lower the maximum battery power can be selected. It should be taken into account when evaluating potential savings that the costs per kilowatt-hour of battery power according to the current state of the art are still relatively high, for example for lithium-ion batteries amount to about 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 .A suitable internal combustion engine is because of its small size and the possibility of installation with a 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 Abbrandtempera- turen von wenigstens 300 0C und wo nötig bis zu 600 0C angehoben werden. 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. Da batteriebetriebene Fahrzeuge schwer zu heizen sind, kann in weiterer Ausgestaltung der Erfindung der Dieselmotor mit einem Wärmetauscher für eine Fahrzeugheizeinrichtung versehen sein.In the interests of the highest possible emission freedom, it is expedient in such diesel engines to use small particle filters in the exhaust gas line, which form a closed collecting 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 as a so-called winding before the particle filter by means of electrical filaments or the like. Abbrandtempera- dummy load to temperatures of at least 300 0 C and are, where necessary, raised up to 600 0 C. The APU can be cooled in a suitable manner, for example by means of air, water or oil cooling, the latter being preferable in the interests of a particularly compact design. Since battery-powered vehicles are difficult to heat, in a further embodiment of the invention, the diesel engine may be provided with a heat exchanger 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.Depending on the location of the housing of the APU inside the vehicle body, it may be appropriate to position the battery pack so that an equalization of the axle loads of the vehicle is achieved. As far as the encapsulation of the APU is concerned, it should be ensured that it is not only completely enveloped by sound-absorbing walls, but also that the air ducts leading to the outside are lined with sound-absorbing materials. This can also be done for the immediate vehicle environment, e.g. the inside of the hood or the boot lid, be appropriate. An APU running when the vehicle is parked is then practically no longer perceptible in the daytime noise.
Im Folgenden wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung erläutert . Es zeigtIn the following an embodiment of the invention will be explained with reference to the drawing. It shows
Fig. 1 den Batterieantrieb eines Elektrofahrzeugs mit Hilfsgeneratoreinheit als schematisches Schaltbild und Fig. 2 zwei Einbaumöglichkeiten einer APU in einem PKW.Fig. 1 shows the battery drive of an electric vehicle with auxiliary generator unit as a schematic diagram and Fig. 2 shows two installation options of an APU in a car.
Gemäß Fig. 1 umfasst eine APU 1 einen Verbrennungsmotor, bevorzugt einen Dieselmotor 2 und einen daran angebauten Permanentmagnet-Generator 3. Die APU liefert Strom über einen Umformer 4 an ein Batteriepaket 6 entsprechend der dort gewünschten Batteriespannung. Über das Batteriepaket 6 fließt Strom über die Leitung 11 zum Elektromotor 10, der über ein nicht gezeichnetes Getriebe die Fahrzeugräder antreibt.According to FIG. 1, an APU 1 comprises an internal combustion engine, preferably a diesel engine 2 and a permanent magnet generator 3 attached thereto. The APU supplies power via a converter 4 to a battery pack 6 in accordance with the battery voltage desired there. Power flows via the battery pack 6 via the line 11 to the electric motor 10, which drives the vehicle wheels via a not-shown gear.
Der Batteriesatz 6 wird von der APU über die Leitung 12 aufgeladen. Andererseits besitzt das Batteriepaket 6 einen Stromeingang 13, welcher an ein Ladegerät 7 angeschlossen ist, welches zwei Eingänge besitzt, nämlich einen Eingang 8, der an das öffentliche Netz anschließbar ist, und einen Eingang 9, der an eine gesonderte Energiequelle z.B. eine Solarstromerzeugereinheit oder eine kleine Blockheizkraftwerkseinheit anschließbar ist.The battery pack 6 is charged by the APU via the line 12. On the other hand, the battery pack 6 has a current input 13 connected to a charger 7 having two inputs, namely an input 8 connectable to the public grid and an input 9 connected to a separate power source e.g. a solar power generator unit or a small combined heat and power unit can be connected.
Eine Steuereinheit 5 sorgt dafür, dass der Ladungszustand des Batteriepakets 6 von der APU erkannt wird, die dann bei Bedarf zugeschaltet wird. Das Zuschalten der APU kann noch durch andere Einflussgrößen gesteuert werden, beispielsweise einer Information über eine vorgewählte Fahrstrecke bzw. eine angestrebte Fahrzeit. Auch die Einbindung eines Navigationssystems in die Steuereinheit könnte vorteilhaft sein, weil auf diese Weise eine vorausschauende Steuerung der APU- Einschaltzeit ermöglicht würde.A control unit 5 ensures that the charge state of the battery pack 6 is detected by the APU, which is then switched on when needed. The connection of the APU can be controlled by other factors, such as information about a preselected route or a desired travel time. The integration of a navigation system in the control unit could be advantageous because of this This would allow predictive control of the APU on-time.
Fig. 2 zeigt an einem schematischen Längsschnitt durch ein Personenkraftfahrzeug zwei mögliche Einbaupositionen der APU, nämlich einmal in der Position 14 unter der Motorhaube und einmal in der Position 15 heckseitig unterhalb des Kofferraumbodens 16. Es sind zwei mögliche Positionen für Teile des Batteriepakets bzw. das jeweilige Batteriepaket eingezeichnet, nämlich bei Position 17 unter der Motorhaube und bei Position 18 im Inneren des Kofferraums. Das Batteriepaket sollte nach Möglichkeit so angeordnet werden, dass beide Fahrzeugachsen z.B. gleich belastet werden oder dass eine angetriebene Achse höher belastet wird. Dabei ist selbstverständlich zu berücksichtigen, wo sich die APU befindet. Zu Fig. 2 wurde darauf verzichtet, irgendwelche Leitungsverbindungen oder sonstige Bauteile gemäß dem zu Fig. 1 beschriebenen Schaltplan darzustellen. Fig. 2 shows a schematic longitudinal section through a passenger car two possible mounting positions of the APU, namely once in the position 14 under the hood and once in the position 15 at the rear below the trunk floor 16. There are two possible positions for parts of the battery pack or respective battery pack located, namely at position 17 under the hood and at position 18 in the interior of the trunk. The battery pack should if possible be arranged so that both vehicle axles e.g. be charged equally or that a driven axle is loaded higher. Of course, it must be taken into consideration where the APU is located.
