Beschreibungdescription
Die Erfindung betrifft eine Sicherheitseinrichtung für ein Kraftfahrzeug, welches zumindest ein Bordnetz und einen Energiespeicher mit mehreren in Reihe geschalteter Energiespeicherzellen aufweist, mit einer Trennvorrichtung, die den Energiespeicher elektrisch vom Bordnetz trennt.The invention relates to a safety device for a motor vehicle, which has at least one electrical system and an energy store with a plurality of energy storage cells connected in series, with a disconnecting device which electrically separates the energy store from the electrical system.
Die Sicherheitseinrichtung ist insbesondere für Hybridfahrzeuge oder Elektrofahrzeuge vorgesehen. Hybridfahrzeuge weisen beispielsweise eine Verbrennungsmaschine und eine elektrische Maschine auf. Die elektrische Maschine ist in der Regel als Starter/Generator und/oder elektrischer Antrieb ausgeführt. Als Starter/Generator ersetzt sie den normalerweise vorhandenen Anlasser und die Lichtmaschine. Bei einer Ausführung als elektrischer Antrieb kann ein zusätzliches Drehmoment, d. h. ein Beschleunigungsmoment, zum Vortrieb des Fahrzeugs von der elektrischen Maschine beigetragen werden. Als Generator ermöglicht sie eine Rekuperation von Bremsenergie. Weiterhin weisen Hybridfahrzeuge mindestens einen Energiespeicher auf. Die Energie aus dem Energiespeicher kann zum Starten des Verbrennungsmotors, für die elektrischen Verbraucher im Fahrzeug und für Beschleunigungsvorgänge benutzt werden. Der Energiespeicher wird während der Fahrt über den Generator vom Verbrennungsmotor gespeist. Zusätzlich wird der Energiespeicher durch Energierückgewinnung beim Bremsen aufgeladen. Über eine Steuerelektronik werden die verschiedenen Modi gesteuert, unter anderem, ob dem Energiespeicher Energie entnommen oder zugeführt werden soll. Elektrofahrzeuge weisen dagegen nur eine oder mehrere elektrische Maschinen auf. Temic Automotive Electric Motors GmbH P TM81537 PCThe safety device is intended in particular for hybrid vehicles or electric vehicles. Hybrid vehicles have, for example, an internal combustion engine and an electric machine. The electric machine is usually designed as a starter / generator and / or electric drive. As a starter / generator it replaces the normally existing starter and alternator. In an embodiment as an electric drive, an additional torque, ie an acceleration torque, can contribute to the propulsion of the vehicle by the electric machine. As a generator, it enables a recuperation of braking energy. Furthermore, hybrid vehicles have at least one energy store. The energy from the energy storage can be used for starting the internal combustion engine, for the electrical consumers in the vehicle and for acceleration processes. The energy storage is powered while driving on the generator from the engine. In addition, the energy storage is charged by energy recovery during braking. Control electronics control the various modes, including whether energy is to be removed or supplied to the energy store. By contrast, electric vehicles have only one or more electrical machines.

Da der Energiespeicher bzw. die einzelnen Energiespeicherzellen bei Bedarf ausgewechselt werden müssen, weil zum Bespiel eine Energiespeicherzelle defekt ist, muss zunächst der Energiespeicher vom Kraftfahrzeugbordnetz getrennt werden. Eine hohe Gesamtspannung des Energiespeichers muss im Reparaturfall getrennt in niedrigeren, physiologisch ungefährlichen Einzelspannungen vorliegen, damit die Person, die die Reparatur vornimmt, zuverlässig vor einer Berührung mit der Bordnetzspannung geschützt wird. Ebenso müssen die Fahrzeuginsassen in Notfällen, wie beispielsweise Unfällen, geschützt werden.Since the energy storage or the individual energy storage cells must be replaced if necessary, for example, an energy storage cell is defective, the energy storage must first be disconnected from the motor vehicle electrical system. A high total voltage of the energy storage device must be present in case of repair separately in lower, physiologically harmless individual voltages, so that the person performing the repair is reliably protected from contact with the vehicle electrical system voltage. Similarly, the vehicle occupants must be protected in emergencies, such as accidents.
Aufgabe der vorliegenden Erfindung ist es, eine Sicherheitseinrichtung bereitzustellen, die eine Trennvorrichtung aufweist, die den Energiespeicher vom Fahrzeugbordnetz trennt sowie die einzelnen Energiespeicherzellen voneinander trennt und somit in mehrere Einzelspannungen teilt.Object of the present invention is to provide a safety device having a separator which separates the energy storage from the vehicle electrical system and the individual energy storage cells separated from each other and thus divides into several individual voltages.
Die Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. Vorteilhafte Weiterbildungen sind den Unteransprüchen zu entnehmen.The object is solved by the features of patent claim 1. Advantageous developments can be found in the dependent claims.
Die Sicherheitseinrichtung ist für ein Kraftfahrzeug vorgesehen, welches zumindest ein Bordnetz und einen Energiespeicher mit mehreren in Reihe geschalteter Energiespeicherzellen aufweist. Die Energiespeicherzellen sind beispielsweise Batterien, Nickel-Metallhydrid-Zellen oder Lithium-Ionen-Zellen. Die Sicherheitseinrichtung weist eine Trennvorrichtung auf, die den Energiespeicher elektrisch vom Bordnetz trennt, und die einzelnen Energiespeicherzellen des Energiespeichers mechanisch und/oder elektrisch voneinander trennt. Dadurch wird die Gesamtspannung des Energiespeichers in mehrere Einzelspannungen entsprechend der Anzahl der Energiespeicherzellen aufgeteilt. Die Einzelspannungen sind um ein Vielfaches niedriger als die Gesamtspannung. In diesem abgesicherten Zustand, d. h. nach Betätigung der Trennvorrichtung, kann dann ein Leistungsanschluss an das Fahrzeug realisiert werden.

The energy storage cells are for example batteries, nickel-metal hydride cells or lithium-ion cells. The safety device has a separating device which electrically separates the energy store from the electrical system, and the individual energy storage cells of the energy storage mechanically and / or electrically separated from each other. As a result, the total voltage of the energy store is divided into a plurality of individual voltages corresponding to the number of energy storage cells. The individual voltages are many times lower than the total voltage. In this safe state, ie after actuation of the separation device, then a power connection to the vehicle can be realized. Temic Automotive Electric Motors GmbH P TM81537 PC
Die Trennung des Energiespeichers vom Bordnetz erfolgt dabei mittels integrierter I nterlock- Kontakte. Bei Betätigung der Trennvorrichtung wird die 'Steuerelektronik des Fahrzeugs veranlasst, den Stromkreis zu unterbrechen. Die Unterbrechung des Stromkreises erfolgt üblicherweise mit Schützen.The separation of the energy storage from the vehicle electrical system takes place by means of integrated interlock contacts. Upon actuation of the disconnect device, the vehicle's control electronics are caused to break the circuit. The interruption of the circuit is usually done with contactors.
Vorzugsweise weist die Trennvorrichtung einen elektrischen Hauptkontakt und einen elektrischen Hilfskontakt auf. Bei Betätigung der Trennvorrichtung werden beide Kontakte geöffnet, wobei der Hilfskontakt beim Trennvorgang vor dem Hauptkontakt öffnet und beim Schließvorgang nach dem Hauptkontakt schließt.Preferably, the separator has a main electrical contact and an auxiliary electrical contact. Upon actuation of the separator both contacts are opened, wherein the auxiliary contact opens during the separation process in front of the main contact and closes after closing the main contact.
Die Trennvorrichtung wird beispielsweise mittels eines Hebels betätigt, der sowohl manuell als auch automatisch betätigt werden kann. Vorzugsweise ist die Trennung des Energiespeichers in die einzelnen Energiespeicherzellen und die Trennung des Energiespeichers vom Bordnetz durch zwei verschiedene Bewegungen der Trennvorrichtung, insbesondere des Hebels, definiert. Beispielsweise wird durch eine translatorische Bewegung der Trennvorrichtung der Energiespeicher vom Bordnetz getrennt und mittels einer anschließenden rotatorischen Bewegung, d. h. einer Drehbewegung, der Energiespeicher in einzelne Energiespeicherzellen getrennt. Es kann natürlich auch zuerst die rotatorische und anschließend die translatorische Bewegung ausgeführt werden. Weiterhin kann der Hebel so ausgestaltet sein, dass er die Schütze verdeckt und diese entsprechend erst im sicheren Zustand, d. h. nach Betätigung des Hebels und somit der Trennvorrichtung, zugänglich macht.The separating device is actuated for example by means of a lever which can be actuated both manually and automatically. The separation of the energy store into the individual energy storage cells and the separation of the energy store from the vehicle electrical system are preferably defined by two different movements of the separating device, in particular of the lever. For example, is separated by a translational movement of the separator of the energy storage from the electrical system and by means of a subsequent rotational movement, d. H. a rotational movement, the energy storage in individual energy storage cells separated. Of course, it is also possible first to perform the rotary and then the translatory movement. Furthermore, the lever can be designed so that it covers the shooter and this accordingly only in the safe state, d. H. after actuation of the lever and thus the separator, makes accessible.
Vorteilhafterweise weist der Hauptkontakt eine integrierte Schmelzsicherung auf. Die Schmelzsicherung verhindert eine Überlastung des Bordnetzes bzw. einen Kurzschluss. Die Schmelzsicherung weist einen elektrischen Leiter mit einem Abschnitt auf, der schmilzt, wenn ein zu hoher Strom durch den Abschnitt fließt. Der Stromkreis wird dann unterbrochen. Da die Schmelzsicherung an der Trennvorrichtung angeordnet ist und diese gut zugänglich sein muss, ist auch die Temic Automotive Electric Motors GmbH P TM81537 PCAdvantageously, the main contact has an integrated fuse. The fuse prevents overloading of the electrical system or a short circuit. The fuse has an electrical conductor with a portion that melts when too much current flows through the portion. The circuit is then interrupted. Since the fuse is located on the separator and this must be easily accessible, is also the Temic Automotive Electric Motors GmbH P TM81537 PC
integrierte Schmelzsicherung gut zugänglich. Das erleichtert ein Austauschen der Sicherung, beispielsweise bei Wartungsarbeiten oder im Schadensfall.integrated fuse easily accessible. This makes it easier to replace the fuse, for example during maintenance work or in the event of damage.
Die Trennvorrichtung wird mittels eines Hebels betätigt, der sowohl manuell als auch automatisch betätigt werden kann. Bei manueller Betätigung wird der Hebel von Hand gezogen. Bei einem Unfall, wie beispielsweise einen Stoss auf das Kraftfahrzeug ist es aber notwendig, dass der Hebel automatisch betätigt wird, um die Sicherheit der Fahrzeuginsassen und auch anderer Personen zu gewährleisten. Insbesondere sind hier Mittel vorgesehen, die den Hebel betätigen.The separating device is actuated by means of a lever which can be actuated both manually and automatically. When manually operated, the lever is pulled by hand. In an accident, such as a shock to the motor vehicle, however, it is necessary that the lever is automatically operated to ensure the safety of the vehicle occupants and other persons. In particular, here means are provided which actuate the lever.
Vorzugsweise umfassen die Mittel einen Sensor und einen Airbag, wobei es sich vorteilhafterweise um einen Beschleunigungssensor handelt. Bei einem plötzlichen Stoss wird der Airbag, insbesondere ein Miniairbag, gezündet, wobei der Airbag so angeordnet ist, dass der Hebel für die Trennvorrichtung problemlos durch den Airbag betätigt wird.Preferably, the means comprise a sensor and an airbag, which is advantageously an acceleration sensor. In the event of a sudden shock, the airbag, in particular a mini-airbag, is ignited, the airbag being arranged in such a way that the lever for the separating device is easily actuated by the airbag.
Weiterhin weist die Sicherheitseinrichtung Verbindungselemente auf. Diese sind durch die Trennvorrichtung zum Schutz vor Berührung verdeckt und lösbar angeordnet. Erst nach Betätigung des Hebels sind die Verbindungselemente zugänglich. So kann eine Abdeckung, die die Sicherheitseinrichtung beispielsweise aufweisen kann und die beispielsweise die Verbindungselemente oder auch die Energiespeicherzellen abdecken kann, erst nach Betätigung der Trennvorrichtung, d. h. in sicherem Zustand, entfernt werden.Furthermore, the safety device has connecting elements. These are covered by the separation device for protection against contact and detachably arranged. Only after pressing the lever, the fasteners are accessible. Thus, a cover, which may have the safety device, for example, and which may cover, for example, the connecting elements or the energy storage cells, only after actuation of the separating device, d. H. in safe condition, to be removed.
Der Vorteil dieser Sicherheitseinrichtung ist, dass diese mehrere Funktionen vereint: mechanisches und elektrisches Trennen (bzw.
