Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Erfassen einer elektrischen Größe eines Akkumulators. Die Vorrichtung kann insbesondere in der Kraftfahrzeugtechnik eingesetzt werden. Hier werden Messelemente eingesetzt, die dazu dienen verschiedene elektrische Größen, wie beispielsweise Spannung oder Strom, zu erfassen. Weiter umfasst die Erfindung ein Verfahren zum Herstellen einer solchen Vorrichtung zum Erfassen einer elektrischen Größe eines Akkumulators.The The invention relates to a device for detecting an electrical Size of one Battery. The device can be used in particular in automotive engineering be used. Here, measuring elements are used, which serve different electrical quantities, such as voltage or electricity. Furthermore, the invention comprises a method for producing such an apparatus for detecting an electrical Size of one Battery.
Zum Erfassen des Ladezustands (state of charge SOC) und des Zustands des Akkumulators selbst (state of health SOH) werden auf Grund der stark zunehmenden Anzahl elektrischer Verbraucher im Kraftfahrzeug immer häufiger Überwachungseinrichtungen für den Akkumulator vorgesehen, die auf Grund der Spannung, die über dem Akkumulator abfällt oder dem Lade- und Entladestrom des Akkumulators auf diese Zustände zurückschließen lassen.To the Detecting the state of charge (SOC) and the state of the accumulator itself (state of health SOH) are due to the strong increasing number of electrical consumers in the motor vehicle always frequent monitoring facilities for the Accumulator provided due to the voltage exceeding the Accumulator drops or let the charging and discharging current of the accumulator back to these states.
Bei einem bekannten Batteriesensor (ATZ/MTZ extra, BMW 523, August 2003) wird ein Messelement, beispielsweise ein Präzisionswiderstand, über Leiterplattenverbinder mit der Leiterplatte, auf der sich die Auswerteelektronik befindet, verlötet. Dieses Verlöten erweist sich als außerordentlich aufwändig, da der Messwiderstand eine sehr hohe Wärmeleitfähigkeit besitzt und bei einem herkömmlichen Lötvorgang die der Lötstelle zugeführte Wärme ableiten würde. Aus diesem Grund muss das Messwiderstandselement vorgeheizt werden, um eine ausreichende Erwärmung der Lötstelle sicherzustellen.at a known battery sensor (ATZ / MTZ extra, BMW 523, August 2003) becomes a measuring element, for example a precision resistor, via PCB connectors with the circuit board on which the transmitter is located, soldered. This soldering proves to be extraordinary consuming, because the measuring resistor has a very high thermal conductivity and at a usual soldering the solder joint dissipate heat supplied would. For this reason, the measuring resistance element must be preheated, for sufficient heating the solder joint sure.
