Abstract
Verfahren zur Analyse des Elektrolytsystems einer Batterie, dadurch gekennzeichnet, dass die über einen Sensor vermessenen akustischen und/oder mechanischen Eigenschaften der flüssigkeitsbefüllten Batterie zur Bestimmung des Elektrolytfüllstandes herangezogen werden, wobei die Batterie durch ein passives Impulsanregesystem angeregt wird.Method for analyzing the electrolyte system of a battery, characterized in that the acoustic and / or mechanical properties of the liquid-filled battery measured by a sensor are used to determine the electrolyte level, the battery being excited by a passive impulse excitation system.
Description
Die Erfindung bezieht sich auf ein Verfahren zur Analyse des Elektrolytsystems einer Batterie. Daneben bezieht sich die Erfindung auch auf die zugehörige Einrichtung zur Durchführung des Verfahrens.The invention relates to a method for analyzing the electrolyte system of a battery. In addition, the invention also relates to the associated device for carrying out the method.
Die Kenntnis des Elektrolytfüllstandes einer Batterie ist wichtig zur Beurteilung ihrer Funktionsfähigkeit. Insbesondere bei Traktionsbatterien wird daher der Füllstand regelmäßig optisch vom Wartungspersonal kontrolliert und wird gegebenenfalls Elektrolyt nachgefüllt. Ggf. erfolgt auch eine automatische Nachfüllung im Elektrolyten mittels einer Schwimmermechanik.The knowledge of the electrolyte level of a battery is important for assessing its functionality. In particular, in the case of traction batteries, the fill level is therefore checked optically by maintenance personnel on a regular basis and, if appropriate, the electrolyte is replenished. Possibly. An automatic refilling in the electrolyte also takes place by means of a float mechanism.
Bei wartungsfreien Autobatterien ist dagegen eine Kontrolle nur noch möglich, wenn bei der Fertigung ein optisches Kontrollsystem, das als so genanntes magisches Auge bezeichnet wird, eingebaut wurde. Dies befindet sich üblicherweise an einer von den sechs Zellen einer 12-Volt-Batterie. Auch hier erfolgt die Kontrolle durch im Allgemeinen geschultes Personal, wobei die Batterie zur Inspektion zugänglich sein muss.In maintenance-free car batteries, however, a control is only possible if the manufacturing an optical control system, which is referred to as a so-called magic eye, was installed. This is usually located on one of the six cells of a 12 volt battery. Again, the control is carried out by generally trained personnel, the battery must be accessible for inspection.
Die Offenlegungsschrift
Davon ausgehend ist es Aufgabe der Erfindung, ein Verfahren anzugeben, mit der letztere Vorgänge automatisiert werden können. Dazu soll eine zugehörige Vorrichtung geschaffen werden.On this basis, it is an object of the invention to provide a method with which the latter operations can be automated. For this purpose, an associated device is to be created.
Die Aufgabe ist erfindungsgemäß durch ein Verfahren gemäß dem Patentanspruch 1 gelöst. Eine zugehörige Einrichtung ist im Patentanspruch 6 angegeben. Weiterbildungen des Verfahrens und der Vorrichtung sind Gegenstand der Unteransprüche.The object is achieved by a method according to
Gemäß der Erfindung werden zur automatischen qualitativen und/oder quantitativen Bestimmung der Elektrolytfüllmenge von Batterien das akustische bzw. das mechanische Verhalten der Batterie ausgewertet. Dies kann einerseits durch Erfassung von Luftschall oder andererseits durch Erfassung von Körperschall erfolgen. Es ist auch möglich, dass der Batteriekörper aktiv angeregt wird, beispielsweise durch mechanisches Anschlagen.According to the invention, the acoustic or mechanical behavior of the battery is evaluated for automatic qualitative and / or quantitative determination of the electrolyte charge of batteries. This can be done on the one hand by detecting airborne sound or on the other hand by detecting structure-borne noise. It is also possible that the battery body is actively excited, for example by mechanical impact.
Die bei der erfindungsgemäßen Vorgehensweise gewonnenen Daten können von einer Kontrolleinheit erfasst werden und stehen dann in elektronischer Form für eine Bewertung im Rahmen eines Batterie-Monitoring zur Verfügung. Zur Auswertung der Daten kann gegebenenfalls ein im Kraftfahrzeug bereits vorhandener Bordcomputer verwendet werden. Eine Inaugenscheinnahme durch Bedienpersonal kann somit entfallen.The data obtained in the procedure according to the invention can be detected by a control unit and are then available in electronic form for evaluation in the context of battery monitoring. If necessary, an on-board computer already present in the motor vehicle can be used to evaluate the data. A visual inspection by operating personnel can thus be omitted.
Im Rahmen der Erfindung können in Verbindung mit einem Batterie-Monitoring-System einzelne Batterietypen mit festgelegtem Elektrolyten, beispielsweise Gel oder Vlies, von Batterien mit flüssigem Elektrolyten unterschieden werden. Es ist somit möglich, bei der Nutzung der Batterie korrekte Betriebsbedingungen einzustellen. Dies kann insbesondere bei der Ladeprozedur einer Kraftfahrzeugbatterie von Bedeutung sein.Within the scope of the invention, in connection with a battery monitoring system, individual battery types with a fixed electrolyte, for example gel or fleece, can be distinguished from batteries with liquid electrolyte. It is thus possible to set correct operating conditions when using the battery. This may be particularly important in the charging procedure of a motor vehicle battery.

Insgesamt ist vorteilhaft, dass nunmehr mit einfachsten Mitteln und somit kostengünstig die Funktionsfähigkeit von mit flüssigen Elektrolyten bestückten Batterien überwacht werden kann, ohne dass die Batterie visuell zugänglich sein müsste. Dies Verfahren eignet sich in besonderer Weise zur Überwachung einer KFZ-StarterbatterieOverall, it is advantageous that now with the simplest means and thus cost the functionality of batteries equipped with liquid electrolyte can be monitored without the battery would have to be visually accessible. This method is particularly suitable for monitoring a motor vehicle starter battery
