Description
Die Erfindung bezieht sich auf eine Vorrichtung zur Überwachung von Batteriezellen einer Traktionsbatterie eines Hybridfahrzeuges oder eines Elektrofahrzeugs. Die Batteriezellen werden von einem Batteriemanagementsystem überwacht.The invention relates to a device for monitoring battery cells of a traction battery of a hybrid vehicle or an electric vehicle. The battery cells are monitored by a battery management system.
Stand der TechnikState of the art
Aktuelle Traktionsbatterien, die in Hybridfahrzeugen oder in Elektrofahrzeugen eingesetzt werden, weisen keinen externen Zugang zu den in Batteriepacks modulweise verbauten Batteriezellen auf. Im Falle eines Ausfalls eines Batteriemanagementsystems (BMS), mit welchem die Batteriezellen von Traktionsbatterien in Fahrzeugen gemeinhin überwacht werden, ist somit die Überwachung der Batteriezelle nicht mehr möglich.Current traction batteries, which are used in hybrid vehicles or in electric vehicles, have no external access to the module in battery packs installed battery cells. In the event of a failure of a battery management system (BMS), with which the battery cells of traction batteries are commonly monitored in vehicles, thus the monitoring of the battery cell is no longer possible.
Darstellung der ErfindungPresentation of the invention
Erfindungsgemäß wird eine Vorrichtung zur Überwachung von Batteriezellen einer Traktionsbatterie eines Hybridfahrzeugs oder eines Elektrofahrzeugs vorgeschlagen, wobei die Batteriezellen von einem Batteriemanagementsystem überwacht werden und zur Bestimmung des Zustandes der Batteriezellen eine jede der Batteriezellen eine Serviceleitung aufweist.According to the invention, a device for monitoring battery cells of a traction battery of a hybrid vehicle or of an electric vehicle is proposed, wherein the battery cells are monitored by a battery management system and for determining the state of the battery cells, each of the battery cells has a service line.
Durch die erfindungsgemäß vorgeschlagene Lösung wird gewährleistet, dass potentiell gefährliche Batteriepacks von ungefährlichen Batteriepacks unterschieden werden können und der Zustand der einzelnen Batteriezellen innerhalb des Batteriepacks auch beim Ausfall eines Batteriemanagementsystems bestimmt werden kann und nicht abhängig von der Funktion des Batteriemanagementsystems ist.The proposed solution according to the invention ensures that potentially dangerous battery packs can be distinguished from harmless battery packs and the state of the individual battery cells within the battery pack can also be determined in the event of a battery management system failure and is not dependent on the function of the battery management system.
In einer weiteren vorteilhaften Ausführung der erfindungsgemäß vorgeschlagenen Lösung ist eine jede der Serviceleitungen mit einem die Berührsicherheit der Serviceleitungen gewährleistenden hochohmigen Widerstand versehen. Bei den eingesetzten hochohmigen Widerständen in den Serviceleitungen handelt es sich um Widerstände, deren Höhe so gewählt wird, dass eine Gefährdung des Menschen durch kritischen Körperdurchfluss ausgeschlossen ist.In a further advantageous embodiment of the solution proposed according to the invention, each of the service lines is provided with a contact resistance of the service lines ensuring high-resistance. The high-resistance resistors used in the service lines are resistors, the height of which is selected so as to preclude a hazard to the person due to critical body flow.
Die Serviceleitungen von den einzelnen Batteriezellen werden bevorzugt an einer Seite des Batteriepacks aus diesem herausgeführt und zu einem Servicestecker geführt. Am Servicestecker sind mithin sämtliche Serviceleitungen zu den Batteriezellen des Batteriepacks angeschlossen. Die Anzahl der Serviceleitungen des Batteriepacks richtet sich somit nach der Anzahl der innerhalb des Batteriepacks verbauten einzelnen Batteriezellen.The service lines from the individual battery cells are preferably led out of one side of the battery pack and out to a service connector. All service lines to the battery cells of the battery pack are connected to the service connector. The number of service lines of the battery pack thus depends on the number of installed within the battery pack individual battery cells.
In einer vorteilhaften Ausgestaltung des der Erfindung zugrunde liegenden Gedankens umfasst entweder der Servicestecker selbst eine Entladungsvorrichtung zum kontrollierten Entladen des Batteriepacks oder ist an eine solche angeschlossen. Beispielsweise können zwei Serviceleitungen, in denen jeweils der hochohmige Widerstand vorgesehen ist, mit Schützen versehen werden, die es erlauben, die hochohmigen Widerstände, die in diesen Serviceleitungen verbaut sind, kurzzuschließen, und somit eine kontrollierte Entladung des Batteriepacks zu ermöglichen. Um dies zu erreichen, sind in zwei der Serviceleitungen besagte eine kontrollierte Entladung ermöglichende Schütze vorgesehen. In einer anderen vorteilhaften Ausführungsvariante des der Erfindung zugrunde liegenden Gedankens können über eine Serviceleitung die Hauptschütze eines Batteriepacks angesteuert werden. Die positives Potential aufweisende und die negatives Potential aufweisende Leitung des Batteriepacks sind über den jeweiligen Hauptschütz mit einem bereits existierenden Hochvolt-Stecker (HV-Stecker) verbunden und nicht mit einem Servicestecker verbunden. Dadurch ist stets die Berührsicherheit des Servicesteckers gegeben, auch für den Fall, dass das Relais „klebt“, d.h. seinen Schaltzustand nicht ändert. Zum Entladen wird der mindestens eine Entladewiderstand extern am Hochvolt-Stecker angeschlossen. Somit besteht die Möglichkeit, über diesen das Batteriepack zu entladen. Hier ist erforderlich, dass die Höhe des Entladewiderstand vor dem Anschließen an das Batteriepack klar erkennbar sein muss. In an advantageous embodiment of the idea underlying the invention, either the service plug itself comprises a discharge device for the controlled unloading of the Battery pack or is connected to such. For example, two service lines, in each of which the high-resistance resistor is provided to be provided with contactors that allow short-circuit the high-resistance resistors installed in these service lines, and thus to allow a controlled discharge of the battery pack. To achieve this, provided in one of the service lines said controlled discharge enabling contactors. In another advantageous embodiment of the idea underlying the invention, the main contactors of a battery pack can be controlled via a service line. The positive potential having and the negative potential having line of the battery pack are connected via the main contactor with an existing high-voltage connector (HV connector) and not connected to a service connector. As a result, the touch safety of the service plug is always given, even in the event that the relay "sticks", ie does not change its switching state. For discharging the at least one discharge resistor is connected externally to the high-voltage connector. Thus it is possible to discharge the battery pack via this. Here it is necessary that the height of the discharge resistor before connecting to the battery pack must be clearly visible.
In einer weiteren vorteilhaften Ausführungsmöglichkeit der Erfindung kann die Batterie mit Hilfe einer in einem Batteriepack verbauten Entladevorrichtung entladen werden. Diese Entladevorrichtung enthält mindestens einen Entladewiderstand sowie mindestens einen Schütz, der über Ansteuerleitungen im Servicestecker angesteuert werden kann.In a further advantageous embodiment of the invention, the battery can be discharged by means of a built-in battery pack unloading device. This discharge device contains at least one discharge resistor and at least one contactor, which can be controlled via control lines in the service connector.
Die über die vorstehend beschriebenen Ausführungsvarianten der erfindungsgemäßen Lösung mögliche kontrollierte Entladung eines Batteriepacks ermöglicht insbesondere eine Erhöhung der Transportsicherheit der Batteriepacks.The possible via the above-described embodiments of the inventive solution controlled discharge of a battery pack allows in particular an increase in the transport safety of the battery packs.
Die einzelnen Batteriezellen des Batteriepacks sind durch Überwachungsleitungen mit einem Modulcontroller (CSC) und/oder einer Batteriesteuereinheit (BCU) verbunden.The individual battery cells of the battery pack are connected by monitoring lines to a module controller (CSC) and / or a battery control unit (BCU).
In weiterer vorteilhafter Ausgestaltung der der Erfindung zugrunde liegenden Lösung kann der Servicestecker standardisiert genormt ausgeführt werden, damit im Falle einer Havarie Feuerwehr bzw. Pannendienste die Servicestecker zweifelsfrei als solche identifizieren können und auch Feuerwehrleute bzw. Mitarbeiter von Pannendiensten eine kontrollierte Entladung eines Batteriepacks herbeiführen können. In vorteilhafter Weise befindet der Servicestecker unmittelbar am Batteriepack, insbesondere an einer nach Einbau des Batteriepacks im Fahrzeug von außen her leicht zugänglichen Stelle, so zum Beispiel benachbart zum Ladestecker.In a further advantageous embodiment of the invention of the underlying solution, the service connector standardized standardized running, so in the event of an accident fire or breakdown services can unambiguously identify the service plugs as such and firefighters or employees of breakdown services can bring about a controlled discharge of a battery pack. Advantageously, the service connector is located directly on the battery pack, in particular on a readily accessible from the outside after installation of the battery pack in the vehicle, such as adjacent to the charging connector.
Vorteile der ErfindungAdvantages of the invention
Die Vorteile der erfindungsgemäß vorgeschlagenen Lösung liegen vor allem darin, dass nunmehr bei einem nicht mehr funktionsfähigen Batteriemanagementsystem oder einem nicht mehr funktionsfähigen Batteriesteuergerät (BCU = Battery Control Unit) über die Serviceleitungen prinzipiell die Möglichkeit besteht, den Zustand einer jeden der im Batteriepack verbauten Batteriezelle über eine Messung der Batteriezellenspannung zu überprüfen. Insbesondere lässt sich durch die erfindungsgemäß vorgeschlagene Lösung ein Isolationswiderstand messen. Für den Fall, dass kein Isolationsfehler vorliegt, können mittels der Serviceleitungen die vorstehend erwähnten, in mindestens zwei dieser Serviceleitungen enthaltenen Schütze geschlossen werden, so dass eine kontrollierte Entladung des Batteriepacks erfolgen kann. Dann können Servicearbeiten am Batteriepack durchgeführt werden.The advantages of the proposed solution according to the invention are, in particular, that now with a no longer functioning battery management system or a battery control unit (BCU = Battery Control Unit) on the service lines in principle, the possibility exists, the state of each of the battery cell installed in the battery pack to check a measurement of the battery cell voltage. In particular, an insulation resistance can be measured by the solution proposed according to the invention. In the event that there is no insulation fault, the above-mentioned contactors contained in at least two of these service lines can be closed by means of the service lines, so that a controlled discharge of the battery pack can take place. Then service work can be performed on the battery pack.
Die einzelnen Serviceleitungen sind mit einem hochohmigen Widerstand versehen, so dass in jedem Falle eine Berührsicherheit der Serviceleitungen gewährleistet ist. Die Höhe des Widerstands ist so gewählt, dass eine Gefährdung des Menschen durch kritischen Körperdurchfluss ausgeschlossen wird.The individual service lines are provided with a high-impedance resistor, so that in each case a touch safety of the service lines is guaranteed. The height of the resistance is chosen so that a hazard to humans is excluded by critical body flow.
Darüber hinaus bleiben die einzelnen Batteriezellen des Batteriepacks über Überwachungsleitungen mit dem Batteriemanagementsystem, bzw. einem Modulcontroller, der Teil eines Batteriesteuergerätes (BCU) ist, verbunden. Für den Fall von deren nicht-Funktionieren, etwa bei Ausfall der Stromversorgung, kann über die erfindungsgemäß vorgeschlagene Lösung eine Überwachung der Batteriezellen auch ohne Einsatz der dieser zugeordneten Elektroniken, wie beispielsweise Batteriemanagementsystem und Batteriesteuergerät, vorgenommen werden. In addition, the individual battery cells of the battery pack remain connected via monitoring lines to the battery management system, or a module controller, which is part of a battery control unit (BCU). In the event of their non-functioning, such as failure of the power supply, can be made on the inventively proposed solution monitoring the battery cells without the use of these associated electronics, such as battery management system and battery control unit.
Als weiterer Vorteil der erfindungsgemäß vorgeschlagenen Lösung ist durch den Servicestecker eine herstellerübergreifende, schnelle Überprüfungsmöglichkeit für gelagerte Batteriepacks gegeben. Dies ist insbesondere dann von Interesse, wenn Elektrofahrzeuge, zum Beispiel als Alternative zu einem langwierigen Aufladevorgang, den oder die komplette Batteriepacks an den Servicestationen austauschen können und die Batteriepacks an dieser Servicestation gelagert werden. As a further advantage of the proposed solution according to the invention is given by the service connector manufacturer-independent, rapid verification option for stored battery packs. This is particularly of interest when electric vehicles, for example, as an alternative to a lengthy charging process, can replace the or the complete battery packs at the service stations and the battery packs are stored at this service station.
