Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren zur Ermittlung des Elektrolytfüllstandes einer Bleibatterie. Daneben bezieht sich die Erfindung auf ein System mit einer Einrichtung zur Durchführung des Verfahrens.The The invention relates to a method for determining the electrolyte level a lead acid battery. In addition, the invention relates to a system with a device for implementation of the procedure.
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 A battery is important for assessing its functionality. Especially with traction batteries, therefore, the level regular optical controlled by maintenance personnel and becomes electrolyte if necessary refilled. Possibly. An automatic refill in the electrolyte also takes place by means of a float mechanics.
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.at maintenance-free car batteries, however, is only a check possible, if in the production of an optical control system, the so-called magic eye is called, was installed. This is usually on one of the six cells of a 12 volt battery. Here too the control is carried out by generally trained personnel, the battery must be accessible for inspection.
Davon ausgehend ist es Aufgabe der Erfindung, ein Verfahren anzugeben, mit der letztere Vorgänge automatisiert werden können. Dazu soll eine zugehörige Vorrichtung geschaffen werden.From that It is an object of the invention to provide a method with the latter operations can be automated. This is an associated Device to be created.
Die Aufgabe ist erfindungsgemäß durch ein Verfahren gemäß dem Patentanspruch 1 gelöst. Eine zugehörige Einrichtung zur Durchführung des Verfahrens ist im Anspruch 10 angegeben. Weiterbildungen des Verfahrens und der zugehörigen Vorrichtung sind Gegenstand der Unteransprüche.The Task is inventively by a method according to the claim 1 solved. An associated one Device for implementation of the method is given in claim 10. Further developments of the Method and the associated Device are the subject of the dependent claims.
Gemäß der Erfindung wird zur automatischen qualitativen und quantitativen Bestimmung der Elektrolytfüllmenge ein kapazitives Sensorprinzip verwendet. Kapazitive Füllstandssensoren sind zwar an sich bekannt, beispielsweise bei Öltanks. Bei der Erfindung kann der Sensor aus zwei parallel angeordneten Elektroden bestehen, die an der Außenseite der Batterie in Höhe des Füllstandes angebracht werden.According to the invention becomes automatic qualitative and quantitative determination the electrolyte filling quantity a capacitive sensor principle used. Capacitive level sensors are known per se, for example in oil tanks. In the invention can the sensor consists of two parallel electrodes, the on the outside the battery in height the level be attached.
Die mit einer solchen Einrichtung gemessenen Signale bzw. die Messdaten können von einer Kontrolleinheit erfasst werden und stehen damit in elektronischer Form für eine Batteriebewertung zur Verfügung. Insbesondere können die Daten in einen bei neueren Kraftfahrzeugen vorhandenen Bordcomputer eingespeist werden.The with such a device measured signals or the measured data can be captured by a control unit and are therefore in electronic form Form for a battery rating available. In particular, you can the data in an on-board computer on newer motor vehicles be fed.
Bei der Erfindung kann der Sensor entweder mit einer Auswerteeinheit physisch verbunden sein. Es ist aber auch möglich, die Messwerte kontaktlos, beispielsweise mittels eines RFID-Tags, zu übertragen.at According to the invention, the sensor may be provided either with an evaluation unit be physically connected. But it is also possible, the measured values contactless, for example using an RFID tag, transferred to.
