Hybrid- oder Elektrofahrzeug Die Erfindung betrifft eine Vorrichtung zur Energieverteilung und/oder Energieum- wandlung in einem Hybrid- oder Elektrofahrzeug gemäß dem Oberbegriff des Pa- tentanspruchs 1. Hybrid or electric vehicle The invention relates to a device for energy distribution and / or energy conversion in a hybrid or electric vehicle according to the preamble of patent claim 1.

Eine Vorrichtung zur Klimatisierung eines Fahrzeuginnenraums eines Elektrofahr- zeugs ist beispielsweise aus WO 2012/169 764 A2 bekannt. Bei dieser bekannten Vorrichtung erfolgt eine Wärmerückgewinnung verschiedener elektrischer Klimati sierungs-Komponenten des Elektrofahrzeugs. A device for air conditioning a vehicle interior of an electric vehicle is known, for example, from WO 2012/169 764 A2. In this known device, there is heat recovery of various electrical climatisation components of the electric vehicle.

Aufgabe der Erfindung ist es, eine Vorrichtung zur Energieverteilung und/oder Energieumwandlung in einem Hybrid- oder Elektrofahrzeug zu schaffen, mittels der die Energieeffizienz eines Hybrid- oder Elektrofahrzeugs wesentlich verbes- sert wird. The object of the invention is to provide a device for energy distribution and / or energy conversion in a hybrid or electric vehicle, by means of which the energy efficiency of a hybrid or electric vehicle is significantly improved.

Diese Aufgabe wird durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den darauf bezogenen Unteransprüchen angegeben. This object is achieved by a device with the features of claim 1. Advantageous refinements of the invention are specified in the dependent claims related thereto.

Die erfindungsgemäße Vorrichtung mit wenigstens einer energieverteilenden und/oder absichernden Einheit, die in der Fachwelt manchmal auch als Power- Distribution-Unit (PDU) bezeichnet wird, und wenigstens einem DC/DC-Wandler zeichnet sich dadurch aus, dass sie wenigstens ein gemeinsames Gehäuse um- fasst, in dem die wenigstens eine energieverteilende und/oder absichernde Ein- heit und der wenigstens eine DC/DC-Wandler angeordnet sind. Vorteilhaft ist im gemeinsamen Gehäuse wenigstens eine weitere Verlustwärme oder Abwärme er- zeugende elektronische, elektrische, elektromechanische oder elektrochemische Vorrichtung, insbesondere weitere Hochvolt-Bauteile, angeordnet. Die Anordnung in einem gemeinsamen Gehäuse ermöglicht eine unmittelbare Verbindung der verschiedenen Bauteile miteinander, so dass eine Anzahl von bislang benötigten Verbindungskabeln und/oder Verbindungssteckern zwischen diesen entfallen o- der zumindest reduziert werden können. Das gemeinsame Gehäuse ermöglicht auch eine sehr kompakte, platz-, gewichts- und kostensparende Unterbringung der verschiedenen Bauteile. Darüber hinaus sind aufgrund der Unterbringung in einem gemeinsamen, gegen elektromagnetische Strahlungen abschirmenden Ge- häuse weniger separat zu prüfende und abzuschirmende Hochvoltkomponenten vorhanden und es ist eine gemeinsame Wärmeableitung oder Kühlung oder eine Nutzung der Abwärme zur Beheizung anderer Komponenten oder des Fahrzeu- ginnenraums möglich. Die Unterbringung aller Verlustwärme oder Abwärme er- zeugenden elektronischen, elektrischen, elektromechanischen oder elektrochemi- schen Bauteile in einem gemeinsamen Gehäuse reduziert die Wärmeverluste auf ein Minimum oder erhöht mit anderen Worten die Energie-Nutzung maximal. Das Gehäuse wird von einem Wärmeträgerstrom durchströmt, der ausgangsseitig mit dem Fahrzeuginnenraum und/oder der Batterie verbunden ist. Das Gehäuse wird bevorzugt von einem Wärmeträgerstrom durchströmt, der ausgangsseitig mit dem Fahrzeuginnenraum und/oder der Batterie verbunden ist. Durch die erfindungsge- mäße Vorrichtung erfolgt ein zentrales, in einem Gehäuse vereinigtes Ther- moenergiemanagement für ein Hybrid- oder Elektrofahrzeug, wobei die bei der Energieübertragung und/oder Energieumwandlung entstehende Verlustwärme ei- nem Wärmeträgerstrom zugeführt wird, welcher das Gehäuse durchströmt. Die Verlustwärme wird dabei möglichst vollständig einem Wärmeträgermedium des Wärmeträgerstroms zugeführt und kann somit an anderer Stelle genutzt werden. Wenn in dieser Anmeldung von„elektronischen Bauteilen“ gesprochen wird, sind davon auch immer elektrische, elektromechanische oder elektrochemische Vor- richtungen mit umfasst. The device according to the invention with at least one energy-distributing and / or securing unit, which is sometimes referred to in the technical field as a power distribution unit (PDU), and at least one DC / DC converter is characterized in that it has at least one common housing around- summarizes in which the at least one energy-distributing and / or securing unit and the at least one DC / DC converter are arranged. At least one additional electronic, electrical, electromechanical or electrochemical device generating heat loss or waste heat, in particular further high-voltage components, is advantageously arranged in the common housing. The arrangement in a common housing enables the various components to be connected directly to one another, so that a number of connecting cables and / or connecting plugs between them which were previously required are eliminated or at least reduced. The common housing also enables a very compact, space, weight and cost-saving accommodation of the various components. In addition, due to the accommodation in a common housing that shields against electromagnetic radiation, there are fewer high-voltage components to be tested and shielded, and common heat dissipation or cooling or use of the waste heat for heating other components or the vehicle interior is possible. All electronic, electrical, electromechanical or electrochemical components that generate waste heat or waste heat are accommodated in a common housing, which reduces heat loss to a minimum or, in other words, increases energy use to the maximum. A heat carrier flow flows through the housing, which is connected on the output side to the vehicle interior and / or the battery. A heat carrier flow is preferably flowed through the housing, which is connected on the output side to the vehicle interior and / or the battery. The device according to the invention provides central thermal energy management for a hybrid or electric vehicle, combined in a housing, the heat loss generated during energy transmission and / or energy conversion being supplied to a heat transfer stream which flows through the housing. The heat loss is fed as completely as possible to a heat transfer medium of the heat transfer stream and can therefore be used elsewhere. When “electronic components” are mentioned in this application, electrical, electromechanical or electrochemical devices are always included.

Besonders vorteilhaft ist vorgesehen, dass im Gehäuse eine Vorrichtung zum La den der Batterie (OBC = On Board Charger) und weitere elektronische Bauteile angeordnet sind, die mit einer Leistungselektronik versehen sind und dadurch ei- nen signifikanten Teil der ihnen zugeführten Energie in Verlustwärme oder Ab- wärme umwandeln. Mit der vorliegenden Erfindung ist es möglich, für alle Bau- teile, die nennenswerte Energieverluste durch Wärmeentwicklung aufweisen, diese Verlustanteile gesammelt einer Beheizung des Fahrzeuginnenraums und/o- der einer Vorerwärmung der Batterie zuzuführen. Die Lader-Schaltung des On Board Chargers kann während des Ladevorgangs oder auch während der Fahrt bevorzugt für eine Bestromung eines Heiz-oder Kühlelements genutzt werden. It is particularly advantageously provided that a device for charging the battery (OBC = On Board Charger) and further electronic components are provided in the housing, which are provided with power electronics and thereby a significant part of the energy supplied to them in heat loss or waste - convert heat. With the present invention, it is possible for all components which have significant energy losses due to heat development to collectively collect these loss parts for heating the vehicle interior and / or for preheating the battery. The charger circuit of the on-board charger can preferably be used for energizing a heating or cooling element during the charging process or even while driving.

Durch die vorliegende Erfindung wird eine Verkleinerung oder ein Wegfall eines separaten Heizers, wie beispielsweise eines PTC-Heizers ermöglicht. Durch den Wegfall zusätzlicher Komponenten wird eine Gewichtsreduzierung möglich, die in Verbindung mit der optimalen Batterietemperatur zu einer Erhöhung der Reich- weite oder einer Verkleinerung der Batteriegröße genutzt werden kann. The present invention enables downsizing or elimination of a separate heater, such as a PTC heater. The elimination of additional components makes it possible to reduce the weight, which, in conjunction with the optimal battery temperature, can be used to increase the range or reduce the battery size.

Besonders bevorzugt weisen die weiteren elektronischen Bauteile wenigstens ei- nen PTC-Heizer und/oder wenigstens einen Wechselrichter und/oder wenigstens eine Steuerung eines Klimakompressors auf. The further electronic components particularly preferably have at least one PTC heater and / or at least one inverter and / or at least one controller of an air conditioning compressor.

Gemäß einer besonders bevorzugten Ausführungsform ist vorgesehen, dass der DC/DC-Wandler als Multi-Port multidirektionaler DC/DC-Wandler mit einem Mehr- wicklungstransformator ausgebildet ist, dessen Eingangsteil wenigstens ein mit einer Primärspule verbundenes Leistungselektronik-Bauteil aufweist und dessen Ausgangsteil mit jeweils mindestens einer von mehreren Sekundärspulen verbun- dene mehrere Leistungselektronik-Bauteile aufweist. Die Leistungselektronik-Bau- teile sind dabei bevorzugt als Transistor, als MOSFET oder als Bipolartransistor mit isolierter Gate-Elektrode (IGBT) ausgebildet. Durch den Mehrwicklungstrans- formator können auf äußerst kompakte Weise aus einer Eingangsspannung un- terschiedliche Ausgangsspannungen für unterschiedliche Leistungselektronik- Bauteile bereitgestellt werden. According to a particularly preferred embodiment, it is provided that the DC / DC converter is designed as a multi-port, multi-directional DC / DC converter with a multi-winding transformer, the input part of which has at least one power electronics component connected to a primary coil and the output part of which has at least one of several secondary coils connected several power electronics components. The power electronics components are preferred as a transistor, as a MOSFET or as a bipolar transistor with insulated gate electrode (IGBT). Thanks to the multi-winding transformer, different output voltages can be provided for different power electronics components from an input voltage in an extremely compact way.

In einer vorteilhaften Ausgestaltung weist die erfindungsgemäße Vorrichtung we- nigstens einen Temperatursensor zur Erfassung der Eintrittstemperatur in das Gehäuse und/oder wenigstens einen Temperatursensor zur Erfassung der Innen- temperatur im Gehäuse und/oder wenigstens einen Temperatursensor zur Mes- sung der Austrittstemperatur aus dem Gehäuse und/oder zur Messung der Tem- peratur des Fahrzeuginnenraums auf. In an advantageous embodiment, the device according to the invention has at least one temperature sensor for detecting the entry temperature into the housing and / or at least one temperature sensor for detecting the inside temperature in the housing and / or at least one temperature sensor for measuring the exit temperature from the housing and / or to measure the temperature of the vehicle interior.

Besonders bevorzugt weist die Vorrichtung zur Wärmerückgewinnung wenigstens ein einen Mikrocontroller umfassendes Steuergerät auf. Diesem Steuergerät wer- den als Eingangssignale Messwerte der vorstehend genannten Temperatursenso- ren zugeführt und das Steuergerät kann anhand dieser Messwerte und der jewei- ligen Temperaturanforderung aus dem Fahrzeuginnenraum oder der von der Fahrzeugbatterie gemeldeten Betriebstemperatur gezielt den Wirkungsgrad der Vorrichtung zum Laden der Batterie und/oder des wenigstens einen weiteren elektronischen Bauteils verändern, um dadurch bei Bedarf gezielt mehr Abwärme in diesen Komponenten zu erzeugen, die dann zu Heizzwecken verwendet wer- den kann. Durch eine gezielte Verschlechterung des Wirkungsgrades können elektronische Komponenten quasi als Heizgerät benutzt werden, die eigentlich dafür nicht vorgesehen sind, wodurch der Einsatz separater Heizgeräte entfallen kann oder diese in ihrer Größe deutlich reduziert ausfallen. The device for heat recovery particularly preferably has at least one control unit comprising a microcontroller. Measured values of the abovementioned temperature sensors are fed to this control unit as input signals, and the control unit can use these measured values and the respective temperature requirement from the vehicle interior or the operating temperature reported by the vehicle battery to selectively determine the efficiency of the device for charging the battery and / or change the at least one further electronic component in order to specifically generate more waste heat in these components if required, which can then be used for heating purposes. Due to a targeted deterioration in efficiency, electronic components can be used as heating devices that are not actually intended for this, which means that separate heating devices can be omitted or their size can be significantly reduced.

Optional ist vorgesehen, dass die Elektronik wenigstens eines der elektronischen Bauteile zur Ansteuerung der Leistung und/oder zur Veränderung des Wirkungs- grades eines anderen elektronischen Bauteils verwendbar ist. Hierdurch kann un- ter Umständen ein Mikrocontroller in der erfindungsgemäßen Vorrichtung erübrigt werden, da die ohnehin vorhandene Steuerungsintelligenz mancher Komponen- ten eine Verwendung zur Steuerung anderer Komponenten ohne weiteres ermög- licht. It is optionally provided that the electronics of at least one of the electronic components can be used to control the power and / or to change the efficiency of another electronic component. This may make a microcontroller in the device according to the invention unnecessary because the existing control intelligence of some components makes it easy to use it to control other components.

Der Wärmeträgerstrom verwendet als Wärmeträger bevorzugt Luft, alternativ dazu aber auch Kühlwasser oder eine Kombination aus beiden. Der Wärmeträ- gerstrom kann dabei so geführt werden, dass die Abwärme der elektronischen Bauteile seriell aufgenommen wird oder alternativ dazu auch zumindest teilweise parallel. Es ist insbesondere vorteilhaft, wenn die Komponenten mit einer niedri- geren Abwärme-Temperatur vor den Komponenten mit einer höheren Abwärme- Temperatur angeordnet sind, so dass bevorzugt eine Kaskade mit einer stetig an- steigenden Temperatur im Wärmeträgerstrom ausgebildet ist. The heat transfer medium preferably uses air as the heat transfer medium, but alternatively also cooling water or a combination of both. The heat transfer stream can be conducted in such a way that the waste heat of the electronic components is absorbed in series or, alternatively, at least partially in parallel. It is particularly advantageous if the components with a lower waste heat temperature are arranged in front of the components with a higher waste heat temperature, so that a cascade with a continuously increasing temperature is preferably formed in the heat transfer stream.

Gemäß einer vorteilhaften Weiterbildung ist der Wärmeträgerstrom mittels we- nigstens einer Fördereinrichtung, wie eines Gebläses oder einer Pumpe beein- flussbar, die ihrerseits ebenfalls bevorzugt zumindest mit ihrem Antriebsmotor im gemeinsamen Gehäuse angeordnet sind. In Verbindung mit der Leistungsansteu- erung und der gezielten Wirkungsgrad-Veränderung der einzelnen elektronischen Bauteile ist durch eine Veränderung der Förderleistung der Fördereinrichtung ein besonders fein dosierbarer Wärmeeintrag in den Fahrzeuginnenraum oder zur Fahrzeugbatterie möglich. According to an advantageous development, the heat carrier flow can be influenced by at least one conveying device, such as a blower or a pump, which in turn is likewise preferably arranged at least with its drive motor in the common housing. In connection with the power control and the targeted change in efficiency of the individual electronic components, a particularly finely adjustable heat input into the vehicle interior or to the vehicle battery is possible by changing the delivery capacity of the conveyor device.

Vorzugsweise weist das gemeinsame Gehäuse zumindest partiell eine wärmeiso- lierende Wandung auf. In Bereichen des Gehäuses, in denen Bauteile mit einer erhöhten Wärmeentwicklung angeordnet sind, kann die Wärmeisolierung der Wandung unterbrochen werden und es können auf der Außenseite der Wandung sogar zusätzliche Kühlrippen am Gehäuse vorgesehen sein. The common housing preferably has at least partially a heat-insulating wall. In areas of the housing in which components with increased heat development are arranged, the thermal insulation of the wall can be interrupted and additional cooling fins can even be provided on the housing on the outside of the wall.

Vorteilhaft ist der aus der Vorrichtung austretende Wärmeträgerstrom mittels einer steuerbaren Weiche für eine Erwärmung des Fahrzeuginnenraums und/oder der Batterie aufteilbar. Dabei können im Steuergerät bevorzugt je nach Außentempe- ratur und Ladezustand der Batterie Prioritäten für eine Batterie-Erwärmung (oder Kühlung) oder für eine Erwärmung oder Kühlung des Fahrzeuginnenraums ge- setzt werden. The heat carrier flow emerging from the device can advantageously be divided by means of a controllable switch for heating the vehicle interior and / or the battery. Depending on the outside temperature and the state of charge of the battery, priorities for battery heating (or Cooling) or for heating or cooling the vehicle interior.

Optional können auch zwei getrennte erfindungsgemäße Vorrichtungen vorgese- hen sein, von denen eine zur Erwärmung des Fahrzeuginnenraums und eine wei- tere zur Erwärmung der Batterie dient. Optionally, two separate devices according to the invention can also be provided, one of which is used to heat the interior of the vehicle and another to heat the battery.

Wenn vorstehend im Zusammenhang mit der erfindungsgemäßen Vorrichtung von einer Erwärmung oder Heizung des Fahrzeuginnenraums oder der Batterie gesprochen wird, ist damit ebenso auch eine Kühlung umfasst. If a heating or heating of the vehicle interior or the battery is mentioned above in connection with the device according to the invention, this also also includes cooling.

Die Erfindung betrifft auch eine vorteilhafte Verwendung einer erfindungsgemä- ßen Vorrichtung in einem Hybrid- oder Elektrofahrzeug. The invention also relates to an advantageous use of a device according to the invention in a hybrid or electric vehicle.

In Figur 1 ist ein Hybrid- oder Elektrofahrzeug 10 schematisch dargestellt, das ei- nen Fahrzeuginnenraum 20 aufweist und mittels eines von einer Batterie 40 ge- speisten Antriebsmotors 50 bewegbar ist. Im Hybrid- oder Elektrofahrzeug 10 sind auch zwei erfindungsgemäße Vorrichtungen 101 schematisch dargestellt, von de- nen mehrere Ausführungsformen 101 , 102, 103 im Detail in den Figuren 2 bis 4 dargestellt sind. In der Regel ist nur eine dieser erfindungsgemäßen Vorrichtun- gen vorhanden. A hybrid or electric vehicle 10 is schematically shown in FIG. 1, which has a vehicle interior 20 and is movable by means of a drive motor 50 fed by a battery 40. In the hybrid or electric vehicle 10, two devices 101 according to the invention are also shown schematically, of which several embodiments 101, 102, 103 are shown in detail in FIGS. 2 to 4. As a rule, only one of these devices according to the invention is present.

Die erfindungsgemäße Vorrichtung 101 wird von einem Wärmeträgerstrom 210 durchströmt, der als Wärmeträger bevorzugt Luft verwendet. Eine alternative oder ergänzende Verwendung von Kühlflüssigkeit ist aber möglich. Wie in Figur 1 dar- gestellt, kann der Wärmeträgerstrom 210 mittels einer Fördereinrichtung, die dort als Gebläse 30 angedeutet ist, bezüglich der Strömungsmenge pro Zeiteinheit va- riiert werden. Optional ist eine Weiche 220 zur Aufteilung des Wärmeträgerstro- mes 210 in variable Anteile vorgesehen, von denen ein erster Anteil dem Fahr- zeuginnenraum 20 und ein zweiter Anteil der Batterie 40 zugeführt wird. The device 101 according to the invention is flowed through by a heat carrier stream 210, which preferably uses air as the heat carrier. An alternative or additional use of coolant is possible. As shown in FIG. 1, the heat transfer stream 210 can be varied in terms of the flow rate per unit of time by means of a conveyor device, which is indicated there as a blower 30. Optionally, a switch 220 is provided for dividing the heat transfer stream 210 into variable parts, a first part of which is supplied to the vehicle interior 20 and a second part of the battery 40.

Die erfindungsgemäße Vorrichtung 101 weist ein gemeinsames Gehäuse 110 auf, das mit einer bevorzugt wärmeisolierenden Wandung 112 versehen ist und in dem alle eine Leistungselektronik aufweisenden Komponenten des Elektrofahr- zeugs 10 enthalten sind. Dies ist insbesondere ein On Board Charger (OBC) 131 und/oder eine auch als Power Distribution Unit (PDU) bezeichnete Energie vertei- lende und/oder absichernde Einheit 121 und/oder ein DC/DC-Wandler 161 und/o- der optional ein stellvertretend für weitere elektronische Komponenten mit„Etc.“ bezeichnetes Bauteil 171 , das beispielsweise von der Steuerungselektronik eines Klimakompressors gebildet sein kann. The device 101 according to the invention has a common housing 110, which is preferably provided with a heat-insulating wall 112 and in which all components of the electric vehicle 10 having power electronics are contained. In particular, this is an on-board charger (OBC) 131 and / or an energy-distributing and / or securing unit 121, also known as a power distribution unit (PDU), and / or a DC / DC converter 161 and / or optional a component 171, which is representative of further electronic components and is labeled “etc.” and can be formed, for example, by the control electronics of an air conditioning compressor.

Im Gehäuse 110 ist ferner ein Steuergerät 140 mit einem Mikrocontroller und ein wenigstens ein PTC-Heizer 150 angeordnet. Das Steuergerät 140 steuert die Leistung des PTC-Heizers 150 entsprechend des Wärmebedarfs für den Fahr- zeuginnenraum 20 und/oder für die Batterie 40. Der PTC-Heizer 150 muss dabei nur die Differenz der Wärmeenergie beisteuern, falls die zuvor durch einen Wär- meträgerstrom 210 von den elektronischen Leistungsbauteilen 121 , 131 , 161 und 171 aufgenommene Abwärme dieser Leistungsbauteile noch nicht ausreichen sollte. Der PTC-Heizer 150 kann bei Bedarf auch als PTC-Kühler 150 betrieben werden, um Bauteile durch Kühlung in deren optimalem Betriebsbereich zu hal- ten. Die Wandung 112 des Gehäuses 110 kann zumindest in Teilbereichen zur Wärmeabfuhr auch gut wärmeableitend ausgebildet sein und insbesondere auf der Außenseite zusätzliche Kühlrippen 114 aufweisen, wie sie exemplarisch nur in Fig. 4 angedeutet sind. A control unit 140 with a microcontroller and at least one PTC heater 150 are also arranged in the housing 110. The control device 140 controls the Power of the PTC heater 150 in accordance with the heat requirement for the vehicle interior 20 and / or for the battery 40. The PTC heater 150 only has to contribute the difference in thermal energy if this was previously achieved by a heat carrier flow 210 from the electronic power components 121, 131, 161 and 171 absorbed waste heat from these power components should not be sufficient. If required, the PTC heater 150 can also be operated as a PTC cooler 150 in order to keep components in their optimum operating range by cooling. The wall 112 of the housing 110 can also be designed to dissipate heat, at least in some areas, and in particular to be heat-dissipating have additional cooling fins 114 on the outside, as are only indicated by way of example in FIG. 4.

Dem Steuergerät 140 werden bevorzugt Temperatursignale eines Temperatur- sensors 180 für die Eintrittstemperatur qi in das Gehäuse 110, eines Temperatur- sensors 190 für die Innentemperatur 2 im Gehäuse 110 vor dem PTC-Heizer 150 und optional eines Temperatursensors 200 für die Austrittstemperatur 3 aus dem Gehäuse 110 zugeführt, so dass das Steuergerät 140 entsprechend der Tempe- raturanforderung für den Fahrzeuginnenraum 20 und/oder die Batterie 40 die Leistung des PTC-Heizers 150 zur Erzeugung der noch benötigten Differenz-Wär- meenergie im Wärmeträgerstrom 210 vor dessen Austritt aus dem Gehäuse 110 ansteuern kann. The control device 140 is preferably temperature signals of a temperature sensor 180 for the entry temperature qi into the housing 110, a temperature sensor 190 for the inside temperature 2 in the housing 110 in front of the PTC heater 150 and optionally a temperature sensor 200 for the exit temperature 3 from the housing 110 supplied, so that the control device 140 according to the temperature requirement for the vehicle interior 20 and / or the battery 40, the power of the PTC heater 150 to generate the still required differential thermal energy in the heat transfer stream 210 before it emerges from the housing 110 can control.

Bei der in Figur 2 dargestellten Ausführungsform der erfindungsgemäßen Vorrich- tung 101 sammelt der Wärmeträgerstrom 210 die Abwärme aller Leistungselek- tronik-Bauteile 121 , 131 , 161 , 171 innerhalb des Gehäuses 110 und das Steuer- gerät 140 steuert den PTC-Heizer 150 für eine Beisteuerung der vor dem Austritt aus dem Gehäuse 110 noch erforderlichen Wärmeenergie-Differenz an. In the embodiment of the device 101 according to the invention shown in FIG. 2, the heat carrier flow 210 collects the waste heat of all power electronics components 121, 131, 161, 171 within the housing 110 and the control device 140 controls the PTC heater 150 for one Contribution of the thermal energy difference still required before exiting the housing 110.

Bei der in Figur 3 dargestellten Ausführungsform einer erfindungsgemäßen Vor- richtung 102 ist der Mikrocontroller des Steuergeräts 140 über eine Steuerleitung 142 mit der PDU 122, über eine Steuerleitung 143 mit der OBC 132, über eine Steuerleitung 146 mit dem DC/DC-Wandler 162 und über eine Steuerleitung 147 mit dem sonstigen elektronischen Bauteil 172 verbunden. Das Steuergerät 140 kann in diesem Fall auf den Wirkungsgrad h der vorstehend genannten elektroni- schen Bauteile 122, 132, 162 und 172 Einfluss nehmen und dadurch deren Wär- meenergie-Abgabe gezielt steuern. Somit hat hier die Steuerung 140 neben der bereits aus der ersten Ausführungsform gemäß Fig. 2 bekannten Ansteuerung des PTC-Fleizers 150 die Möglichkeit, alle weiteren im Gehäuse 110 angeordne- ten Leistungselektronikbauteile 122, 132, 162 und 172 durch eine Herabsetzung von deren Wirkungsgrad h quasi als weitere Heizgeräte zu verwenden. In the embodiment of a device 102 according to the invention shown in FIG. 3, the microcontroller of the control device 140 is connected to the PDU 122 via a control line 142, to the OBC 132 via a control line 143, to the DC / DC converter 162 and to a control line 146 via a control line 147 connected to the other electronic component 172. In this case, the control device 140 can influence the efficiency h of the above-mentioned electronic components 122, 132, 162 and 172 and thereby control their heat energy output in a targeted manner. In this way, in addition to the control of the PTC filler 150 already known from the first embodiment according to FIG. 2, the controller 140 here has the possibility of all other power electronics components 122, 132, 162 and 172 arranged in the housing 110 by reducing their efficiency h quasi to use as additional heaters.

Bei der in Figur 4 dargestellten dritten Ausführungsform ist zusätzlich zur zweiten Ausführungsform gemäß Figur 3 bei einer erfindungsgemäßen Vorrichtung 103 vorgesehen, dass die im OBC 133 vorhandene Steuerungselektronik für das La- demanagement der Batterie 40 des Elektrofahrzeugs 10 über eine Steuerleitung 135 auch die Ansteuerung des PTC-Heizers 153 übernimmt. Dadurch kann das Steuergerät 140 von Aufgaben entlastet oder sogar völlig übrig werden, wenn die Ansteuerung der anderen elektronischen Leistungsbauteile von einer ohnehin vor- handenen Steuerung eines elektronischen Leistungsbauteils, wie im vorstehen- den Beispiel der OBC 133 übernommen wird. In the third embodiment shown in FIG. 4, in addition to the second embodiment according to FIG. 3, a device 103 according to the invention provides that the control electronics in the OBC 133 for the charge management of the battery 40 of the electric vehicle 10 also control the PTC via a control line 135 -Heizers 153 takes over. As a result, the control device 140 can be relieved of tasks or even be completely left over if the control of the other electronic power components is carried out by an already existing control of an electronic power component, as in the above example the OBC 133.

Gemäß der in den Figuren 5 und 6 dargestellten Ausführungsform ist der DC/DC- Wandler als Multi-Port multidirektionaler DC/DC-Wandler 163 mit einem Mehr- wicklungstransformator 1633 ausgebildet, dessen Eingangsteil 1631 wenigstens ein mit einer Primärspule S1634 verbundenes Leistungselektronik-Bauteil 1634 aufweist und dessen Ausgangsteil 1632 mit jeweils mindestens einer von zwei o- der mehreren Sekundärspulen S1635, S1636 bzw. S1637 verbundene mehrere Leistungselektronik-Bauteile 1635, 1636 (bidirektional) bzw. 1637 (unidirektional) aufweist. Die Leistungselektronik-Bauteile 1634, 1635, 1636 bzw. 1637 sind dabei bevorzugt als Transistor, MOSFET oder als Bipolartransistor mit isolierter Gate- Elektrode (IGBT) ausgebildet. Durch den Mehrwicklungstransformator 1633 kön- nen auf äußerst kompakte Weise aus einer Eingangsspannung an der Primär- spule S1634 mittels unterschiedlicher Sekundärspulen S1635, S1636 bzw. S1637 unterschiedliche Ausgangsspannungen für die bevorzugt unterschiedlichen Leis- tungselektronik-Bauteile 1635, 1636 bzw. 1637 bereitgestellt werden. Es versteht sich für den Fachmann, dass die im Ausführungsbeispiel gemäß Fig. 6 gezeigte Anzahl von drei Leistungselektronik-Bauteilen 1635, 1636 bzw. 1637 nur beispiel- haft gewählt ist und für die Erfindung nicht beschränkend ist.
