Abstract

The extender (1) has a switchable clutch (4) arranged between an internal combustion engine (2) i.e. Wankel engine, and a generator (3). The internal combustion engine and the generator are connected to an electric car-side battery (7). Another switchable clutch (6) is arranged between the generator and a climate compressor (5). The climate compressor is driven with the latter switchable clutch from the electric car-side battery over the generator functioning as an electromotor in an operating mode with sufficient charge state of the electric car-side battery and a non-switchable clutch. An independent claim is also included for a method for operating a climate compressor of an air conditioning apparatus of an electric car.

Description

2 andra koppling och sluten kopplingsbar första koppling omsätts ca. 70 till 80 % av den av förbränningsmotorn alstrade och till den kopplingsbara första kopplingen till förfogande stående mekaniska energin till elektrisk energi för laddning av batteriet på elfordonets sida. 2 second coupling and closed connectable first coupling are reacted approx. 70 to 80% of the mechanical energy generated by the internal combustion engine and to the connectable first coupling available mechanical energy to electrical energy for charging the battery on the side of the electric vehicle.

Vid öppnad andra koppling står hela den på förbränningsmotorns sida alstrade mekaniska effekten till förfogande för alstring av elektrisk energi för laddning av batteriet på elfordonets sida.When the second coupling is opened, the entire mechanical power generated on the side of the internal combustion engine is available for generating electrical energy for charging the battery on the side of the electric vehicle.

Om generatorn medelst ett fyr-kvadrant-ställdon kan styras på så sätt att förbrän- ningsmotorn medelst den då som elmotor fungerande generatorn är startbar, kan man av- stå från en separat elstartmotor eller liknande.If the generator can be controlled by means of a four-quadrant actuator in such a way that the internal combustion engine can be started by means of the generator which then functions as an electric motor, a separate electric starter motor or the like can be dispensed with.

I fallet med räckviddsförlängaren enligt uppfinningen står i det driftstillstånd, i vilket den kopplingsbara första kopplingen är sluten och den kopplingsbara andra kopplingen är öppnad, förbränningsmotorns hela effekt till förfogande för alstring av elektrisk energi för laddning av batteriet på elfordonets sida. Om batteriet på elfordonets sida uppvisar ett till- räckligt laddningstillstànd, är det möjligt att öppna den kopplingsbara första kopplingen och att stänga den kopplingsbara andra kopplingen, så att klimatkompressorn kan drivas rent elektriskt. Detta är vid motsvarande situationer av stor fördel, eftersom i detta driftstillstånd bildas inga avgaser.In the case of the range extender according to the invention, in the operating state in which the connectable first clutch is closed and the connectable second clutch is opened, the entire power of the internal combustion engine is available for generating electrical energy for charging the battery on the electric vehicle side. If the battery on the side of the electric vehicle has a sufficient state of charge, it is possible to open the connectable first clutch and to close the connectable second clutch, so that the air compressor can be operated electrically. This is of great advantage in corresponding situations, since no exhaust gases are formed in this operating condition.

Vid ett förfarande enligt uppfinningen för drift av en klimatkompressor hos en kli- matanläggning i ett elfordon försörjs klimatkompressorn från ett medelst en förbrännings- motor hos en räckviddsförlängare via en generator uppladdningsbart batteri på elfordo- nets sida, varvid generatorn som elmotor omvandlar den till den ledda elektriska energin till mekanisk drivenergi för klimatkompressorn.In a method according to the invention for operating a climate compressor in an air conditioning system in an electric vehicle, the climate compressor is supplied from a battery on a side extender rechargeable by means of an internal combustion engine via a generator, whereby the generator as an electric motor converts it to the led electrical energy to mechanical drive energy for the air compressor.

Till modul- resp. konstruktionsenheten, genom vilken räckviddsförlängaren bildas, hör i fallet enligt uppfinningen även klimatkompressorn, dvs. klimatkompressorn är så att säga integrerad i räckviddsförlängaren.For module resp. the construction unit, by means of which the range extender is formed, in the case according to the invention also belongs to the climate compressor, i.e. the climate compressor is, so to speak, integrated in the range extender.

I det följande kommenteras uppfinningen närmare med hjälp av en utföringsform med hänvisning till ritningen, i vars enda figur en utföringsform av en räckviddsförlängare enligt uppfinningen för elfordon samt ett med denna samverkande batteri på elfordonets sida.In the following, the invention is commented on in more detail by means of an embodiment with reference to the drawing, in the only figure of which an embodiment of a range extension according to the invention for electric vehicles and a battery cooperating with it on the side of the electric vehicle.

En i den enda figuren visad utföringsform av en räckviddsförlängare (range- extender) 1 enligt uppfinningen för elfordon har en förbränningsmotor 2, en generator 3, vilken även kan drivas som elmotor, och en kopplingsbar första koppling 4, vilken är an- ordnad mellan förbränningsmotorn 2 och generatorn 3.An embodiment of a range extender 1 according to the invention for electric vehicles shown in the single figure has an internal combustion engine 2, a generator 3, which can also be operated as an electric motor, and a connectable first clutch 4, which is arranged between the internal combustion engine. 2 and the generator 3.

Mellan klimatkompressorn 5 å ena sidan och generatorn 3 å andra sidan är en kopplingsbar andra koppling 6 anordnad. 3 Till räckviddsförlängarens 1 generator 3 är ett batteri 7 på elfordonets sida anslutet.Between the climate compressor 5 on the one hand and the generator 3 on the other hand, a connectable second coupling 6 is arranged. 3 A battery 7 on the side of the electric vehicle is connected to the generator 3 of the range extender 1.

Detta batteri 7 på elfordonets sida är laddningsbart medelst räckviddsförlängarens 1 för- bränningsmotor 2 vid kopplad resp. sluten första koppling 4 via generatorn 3.This battery 7 on the side of the electric vehicle is rechargeable by means of the combustion engine 2 of the range extender 1 when connected resp. closed first connection 4 via generator 3.

Förbränningsmotorn 2, vilken t.ex. kan vara utformad som vankelmotor, är i det vi- sade utföringsexemplet så konstruerad att dess i sitt nominella driftstillstånd vid den slutna resp. kopplade första kopplingen 4 till räckviddsförlängarens 1 generator 3 avgivna effekt är tillräcklig för att driva generatorn 3 med sin nominella effekt. Generatorn 3 å sin sida är så konstruerad att dess nominella effekt är ca tre till fyra gånger så stor som den genom räckviddsförlängns1 klimatkompressor 5 maximalt mottagbara mekaniska effekten.The internal combustion engine 2, which e.g. can be designed as a wobble motor, is in the illustrated embodiment so constructed that in its nominal operating condition at the closed resp. coupled first coupling 4 to the power output of the range extender 1 generator 3 is sufficient to drive the generator 3 with its rated power. The generator 3, on the other hand, is designed so that its nominal power is about three to four times as large as the maximum mechanical power received by the range-extended climate compressor 5.

Hos den i den enda figuren visade utföringsformen är räckviddsförlängarens 1 ge- nerator 3 och klimatkompressor 5 flänsade till en för dessa gemensam flänsdetalj. I driv- förbindelsen mellan generatorn 3 å ena sidan och klimatkompressorn 5 å andra sidan, i vilken den kopplingsbara andra kopplingen 6 är anordnad, finns det dessutom -i den vi- sade utföringsformen - en kilremsdrift 9. Den kopplingsbara andra kopplingen 2 är i det visade utföringsexemplet anordnad mellan kilremsdriften 9 och klimatkompressorn 5.In the embodiment shown in the only fi clock, the range extender 1's generator 3 and climate compressor 5 fl are adapted to a common fl end detail for these. In the drive connection between the generator 3 on the one hand and the air compressor 5 on the other hand, in which the clutchable second clutch 6 is arranged, there is also - in the embodiment shown - a V-belt drive 9. The clutchable clutch 2 is in the shown the exemplary embodiment arranged between the V-belt drive 9 and the air compressor 5.

Räckviddsförlängarens 1 generator 3 kan medelst ett i figuren ej visad fyr-kvadrant- ställdon styras på så sätt att förbränningsmotorn 2 kan startas medelst den som elmotor användbara generatorn.The generator 3 of the range extender 1 can be controlled by means of a four-quadrant actuator not shown in the figure in such a way that the internal combustion engine 2 can be started by means of the generator usable as an electric motor.

Med den ovan beskrivna räckviddsförlängaren 1 är det möjligt att öka räckvidden för batteriet 7 på elfordonets sida. Härtill kopplas resp. sluts den mellan förbränningsmo- torn 2 och generatorn 3 anordnade kopplingsbara första kopplingen 4. I detta driftstillstånd är den mellan generatorn 3 och klimatkompressorn 5 anordnade kopplingsbara andra kopplingen 6 öppnad resp. ej kopplad. l detta driftstillstånd står hela driveffekten, vilken alstras av räckviddsförlängarens 1 förbränningsmotor 2, till förfogande för alstring av elektrisk energi för laddning av batteriet 7 på elfordonets sida.With the range extender 1 described above, it is possible to increase the range of the battery 7 on the side of the electric vehicle. To this is connected resp. the connectable first clutch 4 arranged between the internal combustion engine 2 and the generator 3 is closed. In this operating state, the connectable second clutch 6 arranged between the generator 3 and the air compressor 5 is opened resp. not connected. In this operating state, the entire drive power, which is generated by the combustion engine 2 of the range extender 1, is available for generating electrical energy for charging the battery 7 on the side of the electric vehicle.

Om i det förkopplade driftstillståndet hos räckviddsförlängaren 1 dessutom den kopplingsbara andra kopplingen 6 kopplas resp. sluts, så används en andel av den till den kopplingsbara första kopplingen 4 till förfogande stående mekaniska energin för klimat- kompressorns 5 drift. Hos den ovan beskrivna konstruktionen av förbränningsmotorn 2 resp. generatorn 3 är det säkerställt att i detta drifttillstånd står fortfarande ca. 70 till 80 % av den till den kopplingsbara första kopplingen 4 till förfogande stående mekaniska energi till förfogande för alstring av elektrisk energi för laddning av batteriet 7 på elfordonets sida.In addition, if in the pre-connected operating state of the range extender 1 the connectable second coupling 6 is connected resp. is closed, a proportion of the mechanical energy available to the connectable first coupling 4 is used for the operation of the air compressor 5. In the above-described construction of the internal combustion engine 2 resp. generator 3, it is ensured that in this operating state there are still approx. 70 to 80% of the mechanical energy available to the connectable first coupling 4 for generating electrical energy for charging the battery 7 on the side of the electric vehicle.

Om laddningstillståndet hos batteriet 7 på elfordonets sida är tillräckligt högt, kan genom öppnande av den kopplingsbara första kopplingen 4 och stängning av den kopp- lingsbara andra kopplingen 6 ett driftstillstånd uppnås, i vilket klimatkompressorn 5 drivs rent elektriskt. Klimatkompressorns 5 drivenergi kommer då uteslutande från batteriet 7 på 4 elfordonets sida, vilket befinner sig i ett tillräckligt laddningstillstånd, varvid den mellan batteriet 7 på elfordonets sida å ena sidan och klimatkompressorn 5 å andra sidan anord- nade generatorn 3 fungerar som elmotor. l detta drifttillstånd alstras inga avgaser på grund av klimatkompressorns 5 drift.If the state of charge of the battery 7 on the side of the electric vehicle is sufficiently high, by opening the connectable first clutch 4 and closing the connectable second clutch 6, an operating state can be achieved in which the air compressor 5 is electrically driven. The driving energy of the climate compressor 5 then comes exclusively from the battery 7 on the side of the electric vehicle, which is in a sufficient state of charge, whereby the generator 3 arranged between the battery 7 on the side of the electric vehicle on the one hand and the climate compressor 5 on the other acts as an electric motor. In this operating state no exhaust gases are generated due to the operation of the air compressor 5.
