Stand der TechnikState of the art
Die Erfindung betrifft eine Polklemmenanordnung, beispielsweise für den Anschluss eines Laststromkreises an eine Kraftfahrzeugbatterie, mit einem integrierten Shuntwiderstand mittels dem die Stromgrößen in einer Auswerteschaltung bzw. in einem sogenannten Batteriesensor auswertbar sind, insbesondere für die Zustandserkennung der Batterie als Bestandteil eines Energiemanagementsystem in Kraftfahrzeugen, nach der Gattung des Hauptanspruchs.The The invention relates to a pole terminal arrangement, for example the connection of a load circuit to a motor vehicle battery, with an integrated shunt resistor by means of the current values in an evaluation circuit or in a so-called battery sensor can be evaluated, in particular for state detection the battery as part of an energy management system in motor vehicles, according to the preamble of the main claim.
Eine steigende Anzahl elektrischer Verbraucher in Kraftfahrzeugen erfordert zunehmend den Einsatz des eingangs erwähnten Energiemanagement-Systems in Verbindung mit einer zuverlässigen Batteriezustandserkennung, welche die benötigten Batterie-Informationen aus den messbaren Batteriegrößen Strom, Spannung und Temperatur zur Verfügung stellt. Das elektrische Energie-Management befindet sich dabei in der Regel in einem sogenannten Host-Steuergerät, das mit dem Batteriesensor über eine einfache und kostengünstige serielle Schnittstelle, vorzugsweise ein sogenannter LIN-Bus, kommuniziert.A increasing number of electrical consumers in motor vehicles requires increasingly the use of the energy management system mentioned above in conjunction with reliable battery condition detection, which the required battery information from the measurable Battery sizes current, voltage and temperature provides. The electrical energy management is located usually in a so-called host controller, that with the battery sensor via a simple and inexpensive serial interface, preferably a so-called LIN bus, communicates.

Bei den zuvor beschriebenen bekannten Konzepten ist insbesondere die Verbindungstechnik zwischen der Polklemme, dem Shuntwiderstand und dem eigentlichen Batteriesensor sehr kritisch, da hier hohe Anforderungen hinsichtlich der Dichtheit, der Korrosion und der mechanischen Präzision bestehen. Zum Beispiel kann die bisher übliche Befestigung des Shuntwiderstandes außen an der Polklemme zu einer Deformation bei der Befestigung der Polklemme und damit zu Verformungen des Shuntwiderstandes und letztendlich zu das Messergebnis verfälschenden Widerstandsänderungen in den Übergangsbereichen zum Shuntwiderstand führen.at the known concepts described above is in particular the Connection technology between the pole terminal, the shunt resistor and the actual battery sensor very critical, since there are high requirements in terms of tightness, corrosion and mechanical precision consist. For example, the previously customary attachment the shunt resistor outside of the pole terminal to a deformation in the attachment of the pole terminal and thus to deformations of the Shunt resistance and ultimately falsifying the measurement result Resistance changes in the transition areas lead to shunt resistance.
Offenbarung der ErfindungDisclosure of the invention
Die Erfindung geht von einer Polklemmenanordnung mit einem integrierten Shuntwiderstand zur Auswertung von Stromgrößen in einer Auswerteschaltung aus, wobei der Shuntwiderstand in den Polklemmenkontakt integriert ist und eine über Messleitungen zur Auswertung des am Shuntwiderstand gemessenen Spannungsabfalls die Auswerteschaltung kontaktierbar ist. Gemäß der Erfindung besteht der Shuntwiderstand in vorteilhafter Weise aus einem Blechstapel unterschiedlicher leitender Materialien, der um den Pol herumgelegt ist und außen von einer Anschlussklemme zum elektrisch leitenden Anschluss des Laststromkreises umschlossen ist, wobei aus dem Blechstapel Anschlusszapfen zur Kontaktierung der Messleitungen herausragen.The The invention is based on a pole terminal arrangement with an integrated Shunt resistance for evaluation of current values in an evaluation circuit, wherein the shunt resistor in the pole terminal contact is integrated and one via test leads for evaluation of the voltage drop measured at the shunt resistor, the evaluation circuit is contactable. According to the invention consists of Shunt resistance advantageously different from a stack of sheets conductive materials, which is wrapped around the pole and outside from a terminal to the electrically conductive terminal of Load circuit is enclosed, wherein from the sheet stack connecting pin protrude to contact the test leads.
Bei einer bevorzugten Ausführungsform besteht der Blechstapel aus einem radial innen um den Pol gelegten ersten Blech als elektrischer Leiter, aus einem zweiten um das erste Blech herumgeführten Blech aus einem Shuntwiderstandsmaterial und aus einem dritten um diese Anordnung herumgeführten Blech wiederum als elektrischer Leiter mit Kontakt zur Anschlussklemme, wobei jeweils ein Anschlusszapfen am ersten Blech und ein Anschlusszapfen am dritten Blech vorhanden ist. In besonders vorteilhafter Weise besteht dabei das erste und das dritte Blech aus Kupfer und das zweite Blech aus Manganin.at a preferred embodiment of the sheet stack from a radially inside laid around the pole first sheet as electrical Ladder, from a second sheet passed around the first sheet from a shunt resistor material and from a third around this Arrangement guided sheet again as electrical Conductor with contact to the terminal, each with a connecting pin on the first plate and a connecting pin on the third plate available is. In a particularly advantageous manner, the first and the third sheet of copper and the second sheet of manganin.
Eine Anbringung des erfindungsgemäßen Blechstapels an den Pol lässt sich insbesondere dadurch vereinfachen, dass der Blechstapel vor dem Anfügen an den Pol gemeinsam gewalzt ist. Weiterhin kann in vorteilhafter Weise der Blechstapel auch mittels Laser-Punktschweißung an dem Pol befestigt werden, um eine mechanisch stabile Anordnung zu ermöglichen.A Attachment of the sheet stack according to the invention the pole can be simplified in particular by that the stack of sheets together before attaching to the pole rolled. Furthermore, advantageously, the sheet stack also be attached to the pole by means of laser spot welding, to allow a mechanically stable arrangement.
Die Anschlusszapfen können dabei auf einfache Weise aus Einpresspins zur Kontaktierung mit den Messleitungen zu der Auswerteschaltung oder aus Pins einer Steckverbindung zur Kontaktierung mit den Messleitungen zu der Auswerteschaltung gebildet werden.The Connecting pins can easily from Einpresspins for contacting with the test leads to the evaluation circuit or pins of a connector for contacting the test leads be formed to the evaluation circuit.
Eine vorteilhafte Anwendung der Erfindung ergibt sich, wenn mit die erfindungsgemäße Polklemmenanordnung zur Erfassung der elektrischen Zustandsgrößen einer Batterie eines Kraftfahrzeugs aus dem Laststrom der Batterie die Auswerteschaltung mit dem Shuntwiderstand über die Messleitungen verbunden ist.An advantageous application of the invention results when, with the inventive pole terminal arrangement for detecting the electrical Zu Standgrößen a battery of a motor vehicle from the load current of the battery, the evaluation circuit is connected to the shunt resistor via the test leads.
Vorteilhaft ist die erfindungsgemäße Polklemmenanordnung insbesondere auch dadurch, dass der Shuntwiderstand hierbei nicht in den eigentlichen Batteriesensor integriert ist, sodass eine Verbesserung der Dichtheit durch den Entfall der sonst notwendigen Umspritzung des Shuntwiderstandes gegeben ist. Weiterhin kann eine flexiblere Positionierung der Auswerteschaltung relativ zur Batteriepolnische gewählt werden und die eingangs erwähnte Gefahr einer Deformation und der daraus resultierenden Widerstandsänderung beim Kontaktieren der Polklemme ist stark vermindert.Advantageous is the pole terminal arrangement according to the invention in particular also in that the shunt resistor is not in the actual one Battery sensor is integrated, so improving the tightness given by the omission of the otherwise necessary encapsulation of the shunt resistor is. Furthermore, a more flexible positioning of the evaluation circuit be chosen relative to the battery Polish and the beginning mentioned danger of deformation and the resulting Resistance change when contacting the Polklemme is greatly reduced.
