Description
Die Erfindung betrifft eine Vorrichtung zur induktiven Übertragung elektrischer Energie nach dem Oberbegriff des Anspruchs 1. Derartige Vorrichtungen dienen der induktiven Ladung einer in einem Elektrofahrzeug eingebauten, wiederaufladbaren Batterie. Während der Energieübertragung wird in einem räumlichen Bereich zwischen einer stationären Primärspule und einer fahrzeugseitigen Sekundärspule ein magnetisches Feld hoher Feldstärke und Flussdichte aufgebaut. Dies ist notwendig, um in der Sekundärspule einen für die angestrebte Übertragungsleistung ausreichend hohen Strom zu induzieren.The The invention relates to a device for inductive transmission electrical energy according to the preamble of claim 1. Such Devices are used to inductive charge one in an electric vehicle built-in, rechargeable battery. During the energy transfer is in a spatial Area between a stationary primary coil and a vehicle-side secondary coil built up a magnetic field of high field strength and flux density. This is necessary in the secondary coil for the desired transmission power induce high enough current.
Gelangen Menschen, menschliche Extremitäten oder Tiere in diesen Bereich, so können Körperströme induziert werden. Zwar ist anzunehmen, dass dies im Regelfall zu keiner unmittelbaren Gefährdung führt, insbesondere da keine zeitlich ausgedehnte Präsenz in diesem Bereich zu befürchten ist. Die Möglichkeit einer versehentlichen Belastung von insbesondere Kinder oder Haustieren durch ein starkes Magnetfeld ist jedoch geeignet, die Akzeptanz der induktiven Energieübertragung in manchen Bevölkerungskreisen zu beeinträchtigen.Reach People, human extremities or animals in this area, so body currents can be induced. Although is to assume that this usually does not lead to any immediate danger, in particular there is no time-extended presence to fear in this area is. The possibility accidental exposure to children or pets in particular however, a strong magnetic field is suitable for acceptance the inductive energy transfer in some sections of the population to impair.
Auch ist zu beachten, dass Menschen elektrisch leitfähige Gegenstände in Form von Ringen, Armbändern, Werkzeugen, Implantaten und dergleichen am Körper tragen können. Für Tiere gilt dies in Form von Halsbändern. Werden solche Gegenstände einem starken magnetischen Wechselfeld ausgesetzt, so werden in diesen Wirbelströme induziert, die zu einer von Material, Dauer der Einbringung, der Ausrichtung zum Feld und der Höhe der Feldstärke abhängigen Erwärmung führen. Bei Vorhandensein entsprechender Bedingungen können Temperaturen erreicht werden, die zu Beschädigungen und/oder Gefährdungen führen können. Solche könnten ferner auch von elektrisch leitfähigen Gegenständen ausgehen, die von spielenden Kinder absichtlich aus Neugier in den Feldbereich einer induktiven Energieübertragungsvorrichtung eingebracht werden könnten.Also It should be noted that people use electrically conductive objects in the form of rings, bracelets, Can carry tools, implants and the like on the body. For animals this applies in the form of collars. Become such objects exposed to a strong alternating magnetic field, so are in these eddy currents Induced, resulting in material, duration of insertion, orientation to the field and the height lead the field strength dependent heating. at Presence of appropriate conditions can reach temperatures that will cause damage and / or hazards to lead can. Such could furthermore also of electrically conductive objects out of curiosity in the eyes of children playing on purpose Field region of an inductive energy transfer device introduced could become.
Aufgrund der Charakteristik bisheriger Anwendungen für induktive Energieübertragungssysteme wurde eine Gefährdung solcher Art als nicht relevant bewertet. Bei Fahrzeugen mit Fahrer kann im Rahmen einer Schulung darauf hingewiesen werden, im Betrieb auf das Vorhandensein von Fremdkörpern zu achten und diese vor Inbetriebnahme der induktiven Übertragung zu beseitigen oder die induktive Übertragung im Zweifelsfall zu unterbrechen. Für einen weitgehend automatischen Betrieb oder bei höheren Sicherheitsanforderungen, die beim Einsatz derartiger Systeme in öffentlich zugänglichen Bereichen zu veranschlagen sind, erscheint jedoch die Präsenz von Fremdkörpern im Feldbereich als offenes Sicherheitsproblem. Kritisch ist hierbei insbesondere das Eindringen eines Fremdkörpers während der laufenden Energieübertragung, weil keinesfalls anzunehmen ist, dass der Fahrer eines Fahrzeugs den Feldbereich, d. h. den Zwischenraum zwischen den Gehäusen der Primärspule und der Sekundärspule während der Energieübertragung beobachtet. Vielmehr wird das Fahrzeug im Regelfall während eines überwiegenden Teils eines Ladevorgangs vollkommen unbeaufsichtigt sein.by virtue of the characteristic of previous applications for inductive energy transfer systems became a threat of such kind as not relevant. For vehicles with driver can be pointed out in the context of a training, in the enterprise to the presence of foreign bodies too Pay attention and this before commissioning the inductive transmission eliminate or inductive transmission in case of doubt to interrupt. For a largely automatic operation or higher safety requirements, the use of such systems in publicly accessible However, the presence of foreign bodies in the field area as an open security problem. Critical here in particular the penetration of a foreign body during the current energy transmission, because it is not to be assumed that the driver of a vehicle the Field area, d. H. the space between the housings of the primary coil and the secondary coil while the energy transfer observed. Rather, the vehicle is usually for a predominant Part of a load completely unattended.
Der Erfindung liegt daher die Aufgabe zugrunde, die Betriebssicherheit eines induktiven Energieübertragungssystems hinsichtlich der Präsenz von Fremdkörpern im Feldbereich zu verbessern.Of the The invention is therefore based on the object, the reliability an inductive energy transmission system regarding the presence of foreign bodies in the field area to improve.
Diese Aufgabe wird erfindungsgemäß durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen angegeben.These The object is achieved by a Device solved with the features of claim 1. advantageous Embodiments are specified in the subclaims.
Erfindungsgemäß verfügt bei einer Vorrichtung zur induktiven Übertragung elektrischer Energie von einer stationären Einheit mit mindestens einer Primärinduktivität zu einem benachbart zu dieser stehenden Fahrzeug mit mindestens einer Sekundärinduktivität die stationäre Einheit oder das Fahrzeug über eine Einrichtung zur Detektion des Vorhandenseins eines Gegenstandes innerhalb eines vorbestimmten Raumes, der zumindest den während der Energieübertragung zwischen der Primärinduktivität und der Sekundärinduktivität liegenden Raum umfasst. Dies eröffnet die Möglichkeit, das Eindringen eines Fremdkörpers in den Feldbereich der Energieübertragung festzustellen und in geeigneter Weise zu reagieren.According to the invention has a Device for inductive transmission electrical energy from a stationary unit with at least a primary inductance to a adjacent to this stationary vehicle having at least one secondary inductance, the stationary unit or the vehicle over a device for detecting the presence of an object within a predetermined space, at least during the power transmission between the primary inductance and the Secondary inductance lying Room includes. This opens the possibility, the penetration of a foreign body in the field area of energy transfer determine and respond appropriately.
Es kann ein einzelner berührungsloser Sensor, beispielsweise in Form eines Ultraschall-, Radar- oder Infrarotsensors oder eines elektronischen Bildsensors vorgesehen sein, oder auch mehrere derartige Sensoren, die zweckmäßigerweise zumindest teilweise in das gleiche Gehäuse wie die Primärinduktivität oder die Sekundärinduktivität der Energieübertragungsvorrichtung eingebaut oder daran angebaut sind.It can be a single non-contact Sensor, for example in the form of an ultrasonic, radar or infrared sensor or an electronic image sensor may be provided, or also several such sensors, which expediently at least partially in the same housing like the primary inductance or the Secondary inductance of the energy transmission device installed or attached to it.
Mögliche Kriterien für die Erkennung der Anwesenheit eines Fremdkörpers im Feldbereich der Energieübertragung sind das Abweichen eines Sensorsignals von einem Referenzwert oder -signal, im Fall mehrerer Sensoren Abweichungen der einzelnen Sensorsignale untereinander, sowie eine zeitliche Änderung eines Sensorsignals. Ein typisches Indiz für das Eindringen eines Fremdkörpers in den Feldbereich der Energieübertragung bietet insbesondere das letztgenannte Kriterium. Zu den sinnvollen Reaktionen auf die Anwesenheit eines Fremdkörpers gehören insbesondere die Ausgabe eines Warnsignals, die Deaktivierung der Stromversorgung der Primärinduktivität sowie deren Reaktivierung bei einem Wiederaustritt des Fremdkörpers aus dem Feldbereich.Possible criteria for detecting the presence of a foreign body in the field region of the energy transmission are the deviation of a sensor signal from a reference value or signal, in the case of multiple sensors, deviations of the individual sensor signals from each other, as well as a temporal change of a sensor signal. A typical indication for the penetration of a foreign body into the field region of the energy transmission offers in particular the latter criterion. The sensible reactions to the presence of a foreign body include, in particular, the output of a warning signal, the deactivation of the power supply of the pri märinduktivität and their reactivation in a re-emergence of the foreign body from the field area.
