Elektrofahrzeugen) als auch im Bereich der Konsumgüter (zum Beispiel Laptops und Mobiltelefone) vermehrt wiederaufladbare Batterien zum Einsatz kommen werden, an die sehr hohe Anforderungen bezüglich Zuverlässigkeit, Electric vehicles) and in the consumer goods sector (for example, laptops and mobile phones) more rechargeable batteries will be used to which very high reliability requirements,
Leistungsfähigkeit und Lebensdauer gestellt werden. Performance and life are made.
In Figur 1 ist ein Batteriemodul des Standes der Technik zu sehen. Das 1 shows a battery module of the prior art. The
Batteriemodul umfasst ein Gehäuse, an dessen Oberseite sich ein Battery module includes a housing, at the top of a
Gehäusedeckel befindet und unterhalb des Gehäusedeckels die Kontakte Housing cover is located and below the housing cover, the contacts
angeordnet sind, die mit einer Mehrzahl von Batteriezellen verbunden sind. Die Batteriezellen sind in dem Gehäuse in sogenannten Modulen zusammengefasst und hintereinander angeordnet. Es werden beispielsweise sechs Batteriezellen verspannt und in Reihe geschaltet. Um die Daten einer Batterie, insbesondere einer Lithium-Ionen-Batterie auszulesen, müssen die Batteriezellen miteinander angeschlossen werden. Dies wird in der Regel durch das Anschließen der are arranged, which are connected to a plurality of battery cells. The battery cells are combined in the housing in so-called modules and arranged one behind the other. For example, six battery cells are clamped and connected in series. In order to read the data of a battery, in particular a lithium-ion battery, the battery cells must be connected to each other. This is usually done by connecting the
Batteriezustandserkennung (BZE) an Kontakte realisiert, wobei die Kontakte mit Elektroden verbunden sind, die elektrisch leitfähig sind. Die Battery state detection (BZE) realized on contacts, the contacts are connected to electrodes that are electrically conductive. The
Batteriezustandserkennung wird separat hergestellt und ist über einen separaten Anschluss mit der Batterie angeschlossen. Mit anderen Worten wird die Battenezustandserkennung über Steckkontakte auf das fertige Modul gesteckt. Die notwendige Verkabelung zu den einzelnen Batteriezellen ist bereits im Moduldeckel integriert. Die Battenezustandserkennung ist eine wesentliche Voraussetzung für ein gutesBattery condition detection is made separately and is connected to the battery via a separate connector.

The Batteezustandserkennung is an essential requirement for a good
Elektrisches Energiemanagement, die die Leistungsfähigkeit der Batterie zuverlässig berechnet. Algorithmen für die Battenezustandserkennung nutzen als Eingangsgrößen üblicherweise die Messgrößen Batteriestrom, -Spannung und -temperatur. Auf Basis dieser Größen werden der Ladezustand (State of Charge, SOC), der Batteriezustand bzw. die Leistungsfähigkeit (State of Function, SOF) und der Alterungsgrad (State of Health, SOH) der Batterie bestimmt und dem Elektrischen Energiemanagement als Eingangsgrößen zur Verfügung gestellt. Electrical energy management that reliably calculates the performance of the battery. Algorithms for battery state detection usually use the measured quantities battery current, voltage and temperature as input variables. Based on these quantities, the state of charge (SOC), the battery state or the state of health (SOF) and the state of health (SOH) of the battery are determined and made available to the electrical energy management as input variables ,
Zur Messung der Batteriegrößen wird ein Batteriesensor verwendet, der den Batteriestrom und die -Spannung direkt misst. Die Batterietemperatur wird über eine Temperaturmessung in der Nähe der Batterie bestimmt, da die direkte Messung der Säuretemperatur der Batterie im Fahrzeug einen Eingriff in die Batterie erfordern würde, der aktuell nicht möglich ist. Ein Beispiel für eine Funktion der Battenezustandserkennung ist die To measure the battery sizes, a battery sensor is used, which measures the battery current and voltage directly.

An example of a function of Battenezustandserkennung is the
Startfähigkeitsbestimmung auf Basis des SOF. Beim SOF wird das zukünftige Verhalten der Batterie bei Belastung mit dem Startstrom vorhergesagt. Das heißt, die Battenezustandserkennung bestimmt den Batteriespannungseinbruch bei einem vorgegebenen Startstromprofil. Da das minimale Spannungsniveau für einen erfolgreichen Start bekannt ist, liefert der vorhergesagte  Startability determination based on the SOF. The SOF predicts the future behavior of the battery when loaded with the starting current. That is, the battery state detection determines the battery voltage dip at a given starting current profile. Since the minimum voltage level is known for a successful start, the predicted
Spannungseinbruch ein Maß für die aktuelle Startfähigkeit. Abhängig vom  Voltage drop a measure of the current starting ability. Depending on
Abstand des vorhergesagten Spannungseinbruchs zur Startfähigkeitsgrenze definiert das Elektrische Energiemanagement Maßnahmen zum Erhalt oder zur Verbesserung der Startfähigkeit. The distance between the predicted voltage dip and the starting capability limit defines the electrical energy management measures for maintaining or improving the starting capability.
Die Erfassung der Batteriemessgrößen Strom, Spannung und Temperatur muss sehr genau, dynamisch und zeitsynchron sein. Insbesondere die Messung von Strömen im Bereich einiger mA (Milliampere) bis hin zu Startströmen von mehr als 1000 A (Ampere) stellt hohe Anforderungen an die Sensorik dar. Der The acquisition of the battery measurements of current, voltage and temperature must be very accurate, dynamic and time-synchronized. In particular, the measurement of currents in the range of a few mA (milliamps) up to starting currents of more than 1000 A (amperes) makes high demands on the sensors
