Description
Die Erfindung betrifft eine Kraftfahrzeuglade- und/oder Kraftfahrzeugentladevorrichtung nach dem Oberbegriff des Anspruchs 1.The invention relates to a motor vehicle charging and / or Kraftfahrzeugentladevorrichtung according to the preamble of claim 1.
Aus der
Der Erfindung liegt insbesondere die Aufgabe zugrunde, eine sichere Kraftfahrzeuglade- und/oder Kraftfahrzeugentladevorrichtung bereitzustellen, bei der insbesondere ein Bereich zwischen den Energieübertragungseinheiten sicher abgeriegelt werden kann. Sie wird gemäß der Erfindung durch die Merkmale des Anspruchs 1 gelöst. Weitere Ausgestaltungen ergeben sich aus den Unteransprüchen.The invention is in particular based on the object of providing a safe motor vehicle charging and / or motor vehicle unloading device, in which, in particular, a region between the energy transfer units can be securely sealed off. It is achieved according to the invention by the features of claim 1. Further embodiments emerge from the subclaims.
Die Erfindung geht aus von einer Kraftfahrzeuglade- und/oder Kraftfahrzeugentladevorrichtung für ein Elektro- und/oder Hybridkraftfahrzeug, mit zumindest einer ersten Energieübertragungseinheit, die in einem Lade- und/oder Entladevorgang zur kontaktlosen Kopplung mit zumindest einer zweiten Energieübertragungseinheit vorgesehen ist, und mit zumindest einer Schutzvorrichtung, die dazu vorgesehen ist, ein Eindringen von Fremdkörpern in einen Bereich zwischen den Energieübertragungseinheiten während des Lade- und/oder Entladevorgangs zu verhindern.The invention is based on a motor vehicle charging and / or motor vehicle unloading device for an electric and / or hybrid motor vehicle, with at least one first energy transfer unit, which is provided in a charging and / or discharging operation for contactless coupling with at least one second energy transfer unit, and with at least a protection device intended to prevent foreign bodies from entering a region between the energy transfer units during the charging and / or discharging process.
Es wird vorgeschlagen, dass die Kraftfahrzeuglade- und/oder Kraftfahrzeugentladevorrichtung eine Überwachungsvorrichtung aufweist, die dazu vorgesehen ist, die Schutzvorrichtung während des Lade- und/oder Entladevorgangs zu überwachen. Dadurch kann die Schutzvorrichtung während des Lade- und/oder Entladevorgangs vorteilhaft auf eine ordnungsgemäße Funktionalität hin überwacht werden, wodurch der Bereich zwischen den Energieübertragungseinheiten vorteilhafter Weise insbesondere sicher abgeriegelt werden kann. Unter einer „Energieübertragungseinheit” soll dabei insbesondere eine Einheit verstanden werden, die dazu vorgesehen ist, kontaktlos eine elektrische Energie zu empfangen oder zu versenden. Vorzugsweise sind dabei zwei Energieübertragungseinheiten für eine kontaktlose Übertragung von elektrischer Energie über eine definierte Distanz vorgesehen. Vorzugsweise weist die „Energieübertragungseinheit” dabei zumindest eine Spule auf. Unter einer „kontaktlosen Kupplung” soll hier insbesondere eine elektromagnetische, vorzugsweise eine induktive Kopplung verstanden werden. Unter einer „Schutzvorrichtung” soll insbesondere eine mechanische Schutzvorrichtung verstanden werden, die das Eindringen von Fremdkörpern in den Bereich zwischen den Energieübertragungseinheiten durch eine mechanische Barriere verhindert. Unter einer „Überwachungsvorrichtung” soll dabei insbesondere eine Vorrichtung verstanden werden, die physikalische Größen, die mit der ordnungsgemäßen Funktionalität der Schutzvorrichtung zusammenhängen, überprüft und auswertet. Unter „vorgesehen” soll insbesondere speziell programmiert, ausgelegt und/oder ausgestattet verstanden werden. Unter einem „Ladevorgang” soll dabei insbesondere ein Vorgang verstanden werden, bei dem eine Akkuvorrichtung des Kraftfahrfahrzeugs über die Energieübertragungseinheiten funktionell mit einer externen Stromquelle verbunden wird und so mit einer elektrischen Energie geladen wird. Unter einem „Entladevorgang” soll dabei insbesondere ein Vorgang verstanden werden, bei dem eine Akkuvorrichtung des Kraftfahrfahrzeugs über die Energieübertragungseinheiten funktionell mit dem externen Stromnetz verbunden wird, sich über das Stromnetz entlädt und dadurch Strom von der Akkuvorrichtung in das externe Stromnetz eingespeist wird.It is proposed that the motor vehicle loading and / or motor vehicle unloading device has a monitoring device which is provided to monitor the protective device during the loading and / or unloading process. As a result, the protective device can advantageously be monitored for proper functionality during the charging and / or discharging process, as a result of which the area between the energy transfer units can advantageously be reliably sealed off, in particular. A "power transmission unit" should be understood to mean, in particular, a unit which is intended to receive or send out contactless electrical energy. Preferably, two energy transmission units are provided for a contactless transmission of electrical energy over a defined distance. The "energy transfer unit" preferably has at least one coil. A "contactless coupling" is to be understood here in particular as an electromagnetic, preferably an inductive coupling. A "protective device" is to be understood in particular as a mechanical protective device which prevents the penetration of foreign bodies into the region between the energy transmission units by a mechanical barrier. A "monitoring device" is to be understood in particular as meaning a device which checks and evaluates physical quantities which are connected with the proper functionality of the protective device. By "provided" is intended to be understood in particular specially programmed, designed and / or equipped. A "charging process" is to be understood in particular as a process in which a battery device of the motor vehicle is functionally connected to an external power source via the energy transfer units and is thus charged with electrical energy. A "discharge process" is to be understood in particular a process in which a battery device of the motor vehicle is connected via the power transmission units functionally connected to the external power grid, discharges through the mains and thereby power is fed from the battery device into the external power grid.
Weiter wird vorgeschlagen, dass die Schutzvorrichtung zumindest ein aufblasbares Schutzsegment aufweist. Dadurch kann die Schutzvorrichtung besonders vorteilhaft und in einem unbenutzten Zustand platzsparend ausgestaltet werden. Unter einem „aufblasbaren Schutzsegment” soll dabei insbesondere ein Segment verstanden werden, das einen Innenraum aufweist, der zur Ausformung des Schutzsegments zu seiner vollen Größe mit einem Gas, vorzugsweise Luft, gefüllt werden kann. Vorzugsweise besteht das „Schutzsegment” dabei aus einem elastischen Material, das in einem inaktivierten Zustand der Schutzvorrichtung ein, im Vergleich zu seinem vollen Volumen in einem aktivierten Zustand, kleines Volumen aufweist.It is further proposed that the protective device has at least one inflatable protective segment. As a result, the protective device can be designed to be particularly advantageous and save space in an unused state. An "inflatable protection segment" should be understood to mean, in particular, a segment which has an inner space which can be filled to its full extent with a gas, preferably air, for forming the protective segment. In this case, the "protective segment" preferably consists of an elastic material which, in an inactivated state of the protective device, has a small volume compared to its full volume in an activated state.
Ferner wird vorgeschlagen, dass die erste Energieübertragungseinheit, mit der die Schutzvorrichtung fest verbunden ist, als eine Energieempfangseinheit ausgeführt ist und dazu vorgesehen ist, mit einer Akkuvorrichtung verbunden zu werden. Dadurch ist die Schutzvorrichtung vorteilhaft an dem Kraftfahrzeug angebracht, wodurch die Schutzvorrichtung unabhängig von einem Ladeort immer vorhanden ist. Unter einer „Akkuvorrichtung” soll dabei insbesondere eine Vorrichtung zum Speichern elektrischer Energie verstanden werden. Die Akkuvorrichtung wird dabei in einem Ladevorgang mit elektrischer Energie versorgt, die in der Akkuvorrichtung gespeichert wird. Unter „als Energieempfangseinheit ausgeführt” soll hierbei insbesondere in dem Ladevorgang zum Empfang der Energie vorgesehen verstanden werden.It is also proposed that the first power transmission unit, with which the protective device is firmly connected, is designed as a power receiving unit and is intended to be connected to a rechargeable battery device. As a result, the protection device is advantageously attached to the motor vehicle, whereby the protection device is always present regardless of a charging location. A "battery device" is to be understood in particular as a device for storing electrical energy. The battery device is supplied in a charging process with electrical energy that is stored in the battery device. Under "designed as an energy receiving unit" is intended here in particular in the Charging process intended to receive the energy provided.
Des Weiteren wird vorgeschlagen, dass die Überwachungsvorrichtung zumindest eine Sensoreinheit aufweist, die dazu vorgesehen ist, ein Sensorsignal zur Erkennung eines Fehlerfalls der Schutzvorrichtung bereitzustellen. Dadurch kann die Schutzvorrichtung besonders einfach auf eine ordnungsgemäße Funktionalität geprüft werden. Unter einer „Sensoreinheit” soll dabei insbesondere eine Einheit verstanden werden, die eine physikalische Größe erfasst und ein von der physikalischen Größe abhängiges Sensorsignal ausgibt. Unter einem „Sensorsignal” soll dabei insbesondere ein elektrisches und/oder elektronisches Signal verstanden werden, das von der Sensoreinheit ausgegeben wird und dann vorzugsweise von einer elektronischen Auswerteeinheit ausgewertet wird. Vorzugsweise ist das Sensorsignal dabei abhängig von einer physikalischen Größe und verändert sich mit einer Veränderung der physikalischen Größe.Furthermore, it is proposed that the monitoring device has at least one sensor unit which is provided to provide a sensor signal for detecting a fault of the protective device. As a result, the protective device can be checked particularly simply for proper functionality. In this case, a "sensor unit" is to be understood as meaning, in particular, a unit which detects a physical variable and outputs a sensor signal dependent on the physical quantity. A "sensor signal" is to be understood in particular as an electrical and / or electronic signal which is output by the sensor unit and is then preferably evaluated by an electronic evaluation unit. The sensor signal is preferably dependent on a physical quantity and changes with a change in the physical quantity.
Ferner wird vorgeschlagen, dass die Überwachungsvorrichtung bei einem erkannten Fehlerfall dazu vorgesehen ist, einen Start des Lade- und/oder Entladevorgangs zu verhindern und/oder den Lade- und/oder Entladevorgang abzubrechen. Dadurch kann eine möglicherweise gefährliche Situation durch den Lade- und/oder Entladevorgang vorteilhaft verhindert werden.It is also proposed that the monitoring device is provided in a detected error case to prevent a start of the loading and / or unloading and / or cancel the loading and / or unloading. As a result, a potentially dangerous situation can advantageously be prevented by the loading and / or unloading process.
Zudem wird vorgeschlagen, dass die Sensoreinheit zumindest einen Drucksensor aufweist, der dazu vorgesehen ist, einen Druck in dem wenigstens einen Segment der Schutzvorrichtung zu erfassen. Dadurch kann die ordnungsgemäße Funktionalität der Schutzvorrichtung besonders einfach überprüft werden.In addition, it is proposed that the sensor unit has at least one pressure sensor which is provided to detect a pressure in the at least one segment of the protective device. As a result, the proper functionality of the protection device can be checked particularly easily.
In einer besonders vorteilhaften Ausgestaltung wird vorgeschlagen, dass die Überwachungsvorrichtung eine Auswerteeinheit aufweist, in der zumindest ein Druckgrenzwert hinterlegt ist und die dazu vorgesehen ist, ein Unterschreiten des Druckgrenzwerts durch einen von dem Drucksensor erfassten Druckwert als Fehlerfall zu erkennen. Dadurch kann vorteilhaft ein Fehlerfall erkannt werden, bei dem die aufblasbaren Segmente der Schutzvorrichtung nicht ausreichend gefüllt sind und somit eine ordnungsgemäße Funktionalität der Schutzvorrichtung nicht vorliegt. Unter einer „Auswerteeinheit” soll dabei insbesondere eine Funktionalität einer elektronischen Recheneinheit verstanden werden. Vorzugsweise ist die „Auswerteinheit” dabei als Bestandteil einer Steuer- und/oder Regeleinheit ausgebildet. Unter einer „Steuer- und/oder Regeleinheit” soll insbesondere eine Einheit mit zumindest einem Steuergerät verstanden werden. Unter einem „Steuergerät” soll insbesondere eine Einheit mit einer Prozessoreinheit und mit einer Speichereinheit sowie mit einem in der Speichereinheit gespeicherten Betriebsprogramm verstanden werden. Grundsätzlich kann die Steuer- und/oder Regeleinheit mehrere untereinander verbundene Steuergeräte aufweisen, die vorzugsweise dazu vorgesehen sind, über ein Bus-System, wie insbesondere ein CAN-Bus-System, miteinander zu kommunizieren.In a particularly advantageous embodiment, it is proposed that the monitoring device has an evaluation unit in which at least one pressure limit value is stored and which is provided to detect an undershooting of the pressure limit value by a pressure value detected by the pressure sensor as an error case. As a result, it is advantageously possible to detect an error situation in which the inflatable segments of the protective device are not sufficiently filled and thus a proper functionality of the protective device is not present. An "evaluation unit" should be understood to mean in particular a functionality of an electronic processing unit. Preferably, the "evaluation unit" is designed as part of a control and / or regulating unit. A "control and / or regulating unit" is to be understood in particular as a unit having at least one control unit. A "control unit" is to be understood in particular as meaning a unit having a processor unit and a memory unit as well as an operating program stored in the memory unit. In principle, the control and / or regulating unit can have a plurality of interconnected control units, which are preferably provided to communicate with one another via a bus system, in particular a CAN bus system.
Weiterhin wird vorgeschlagen, dass die Sensoreinheit zumindest einen Temperatursensor aufweist, der dazu vorgesehen ist, eine Temperatur in dem Bereich zwischen den Energieübertragungseinheiten zu erfassen. Dadurch kann insbesondere vorteilhaft ein Fehlerfall erkannt werden, bei dem sich ein Fremdkörper in dem Bereich zwischen den Energieübertragungseinheiten befindet, wodurch insbesondere vorteilhaft eine indirekte Überwachung der Schutzvorrichtung erreicht werden kann.Furthermore, it is proposed that the sensor unit has at least one temperature sensor which is provided to detect a temperature in the region between the energy transmission units. As a result, it is particularly advantageous to detect an error case in which a foreign body is located in the region between the energy transmission units, as a result of which, in particular, indirect monitoring of the protective device can be achieved.
Des Weiteren wird vorgeschlagen, dass auf der Auswerteeinheit zumindest ein Temperaturgrenzwert hinterlegt ist und die Auswerteeinheit dazu vorgesehen ist, ein Überschreiten des Temperaturgrenzwerts durch einen von dem Temperatursensor erfassten Temperaturwert als Fehlerfall zu erkennen. Dadurch kann besonders einfach der Fehlerfall erkannt werden, bei dem sich ein Fremdkörper in dem Bereich zwischen den Energieübertragungseinheiten befindet und sich durch den magnetischen Fluss erhitzt.Furthermore, it is proposed that at least one temperature limit value is stored on the evaluation unit and the evaluation unit is provided to detect an exceeding of the temperature limit value by a temperature value detected by the temperature sensor as an error case. As a result, it is particularly easy to detect the fault situation in which a foreign body is located in the area between the energy transfer units and heats up due to the magnetic flux.
