Zumindest Elektrofahrzeuge und Hybridfahrzeuge weisen eine Traktionsbatterie, insbesondere eine Lithium-Ionen-Batterie, auf, welche eine vorgebbare Anzahl von seriell und/oder parallel miteinander verschalteten Einzelzellen besitzt, die zu einem Zellblock zusammengefasst sind. Eine vorgebbare Anzahl von Einzelzellen ist mittels einer Zellüberwachungseinheit überwachbar, wobei ein Potential der jeweiligen Einzelzelle erfassbar ist. Aufgabe der Zellüberwachungseinheit ist es, eine Spannung der einzelnen Einzelzellen zu überwachen. Ein Batteriemanagementsystem ist mit allen Zellüberwachungseinheiten der Batterie verbunden, wobei die einzelnen Zellüberwachungseinheiten als Zellüberwachungselektronik zusammengefasst sind. Dabei bildet das Batteriemanagementsystem eine zentrale Steuer- und Überwachungseinheit der Batterie. Das Batteriemanagementsystem weist eine Diagnoseschnittstelle auf, über die einerseits eine Kommunikation mit im Fahrzeug oder in der Umgebung vorhandenen Steuergeräten möglich ist und andererseits Parameter der Batterie, wie z. B. eine Temperatur abgefragt werden können. Darüber hinaus ist die Batterie an einen so genannten Interlockkreis angeschlossen, welcher eine Sicherheitskomponente im Betrieb der Batterie darstellt.At least electric vehicles and hybrid vehicles have a traction battery, in particular a lithium-ion battery, which has a predeterminable number of serially and / or parallel interconnected individual cells, which are combined to form a cell block. A predeterminable number of individual cells can be monitored by means of a cell monitoring unit, wherein a potential of the respective individual cell can be detected. The task of the cell monitoring unit is to monitor the voltage of the individual cells. A battery management system is connected to all cell monitoring units of the battery, wherein the individual cell monitoring units are combined as cell monitoring electronics. The battery management system forms a central control and monitoring unit of the battery. The battery management system has a diagnostic interface on the one hand, a communication with existing in the vehicle or in the environment control units is possible and on the other hand, parameters of the battery, such. B. a temperature can be queried. In addition, the battery is connected to a so-called Interlockkreis, which represents a safety component in the operation of the battery.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zur Zustandsüberwachung, insbesondere zur Ladezustandsüberwachung einer Batterie anzugeben.The invention has for its object to provide a method and apparatus for condition monitoring, in particular for state of charge monitoring of a battery.
Die Aufgabe wird erfindungsgemäß hinsichtlich des Verfahrens durch die in Anspruch 1 und hinsichtlich der Vorrichtung durch die in Anspruch 5 angegebenen Merkmale gelöst.The object is achieved with respect to the method by the in
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Bei einem Verfahren zur Zustandsüberwachung, insbesondere zur Ladezustandsüberwachung einer Anzahl von Batterien weist jede der zu überwachenden Batterien eine Batterieüberwachungseinheit auf, welcher eine eindeutige Identifikationsbezeichnung zugeordnet wird, wobei die Batterieüberwachungseinheit mit einer zentralen Ladevorrichtung verbunden wird und mittels der zentralen Ladevorrichtung zur Ermittlung des Ladezustandes einer einzelnen Batterie deren Batterieüberwachungseinheit angesteuert wird und mittels der Batterieüberwachungseinheit ein Datenübertragungsweg sowie eine Spannungsversorgung zwischen einem Batteriemanagementsystem der Batterie und der zentralen Ladevorrichtung freigegeben wird und mittels der zentralen Ladevorrichtung Parameter der Batterie über den Datenübertragungsweg abgefragt werden und die Batterie bei ermitteltem kritischen Ladezustand automatisch geladen wird und bei ermitteltem nicht kritischen Ladezustand eine Datenübertragung und die Spannungsversorgung zwischen dem Batteriemanagementsystem und der zentralen Ladevorrichtung mittels derselben automatisch beendet werden.In a method for condition monitoring, in particular for state of charge monitoring of a number of batteries, each of the batteries to be monitored has a battery monitoring unit to which a unique identification designation is assigned, wherein the battery monitoring unit is connected to a central charging device and by means of the central charging device for determining the state of charge of a single Battery whose battery monitoring unit is controlled and by means of the battery monitoring unit a data transmission path and a power supply between a battery management system of the battery and the central charging device is released and queried by means of the central charging device parameters of the battery via the data transmission and the battery is automatically loaded at a determined critical state of charge and at determined non-critical state of charge data transmission and the voltage Ver supply between the battery management system and the central charging device are automatically terminated by the same.
Mittels des erfindungsgemäßen Verfahrens ist es in besonders vorteilhafter Weise möglich, eine große Anzahl von Batterien hinsichtlich ihres Zustandes, beispielsweise in einer Werkstatt, in einem Lager oder in einer Produktionsumgebung ohne großen Aufwand zu überwachen.By means of the method according to the invention, it is possible in a particularly advantageous manner to monitor a large number of batteries with regard to their condition, for example in a workshop, in a warehouse or in a production environment without much effort.
Somit ist es möglich, zumindest einen Zeitaufwand und einen Personaleinsatz zur Ermittlung der Zustände der einzelnen zu überwachenden Batterien zu vermindern.Thus, it is possible to reduce at least a time and a staff deployment to determine the states of the individual batteries to be monitored.
Zudem kann mittels der Parameterabfrage hinsichtlich der jeweiligen Batterie ein Befund erstellt werden, wodurch ermittelt werden kann, ob die Batterie „gesund” ist, um diese beispielsweise in einem Fahrzeug, insbesondere einem Elektrofahrzeug oder einem Hybridfahrzeug, als Traktionsbatterie anzuordnen.In addition, by means of the parameter query with respect to the respective battery, a finding can be made, whereby it can be determined whether the battery is "healthy" in order to arrange it, for example, in a vehicle, in particular an electric vehicle or a hybrid vehicle, as a traction battery.
Ausführungsbeispiele der Erfindung werden im Folgenden anhand einer Zeichnung näher erläutert.Embodiments of the invention will be explained in more detail below with reference to a drawing.
Dabei zeigt:Showing:
In der einzigen Figur ist eine Topologie einer Vorrichtung zur Zustandsüberwachung, insbesondere zur Ladezustandsüberwachung von neun Batterien
Die Batterien
Eine solche Batterie
Eine vorgebbare Anzahl der Einzelzellen des Zellblockes ist mit einer nicht gezeigten Zellüberwachungseinheit verbunden, welche die Einzelzellen überwacht, wobei eine Zellspannung der Einzelzellen an den Zellverbindern gemessen wird. A definable number of the individual cells of the cell block is connected to a cell monitoring unit, not shown, which monitors the individual cells, wherein a cell voltage of the individual cells is measured at the cell connectors.
Wird eine Zellspannung gemessen, welche einen unteren Grenzwert unterschreitet, wird die Einzelzelle abgeschaltet, um eine Tiefenentladung zu vermeiden. Wird eine Zellspannung gemessen, welche einen oberen Grenzwert überschreitet, wird die Einzelzelle ebenfalls abgeschaltet, wodurch eine Überladung dieser Einzelzelle vermieden werden soll.If a cell voltage is measured which falls below a lower limit, the single cell is switched off in order to avoid a deep discharge. If a cell voltage is measured which exceeds an upper limit value, the individual cell is likewise switched off, as a result of which overcharging of this individual cell is to be avoided.
