Der Verpolschutz umfasst dabei einen Sensor, From DE 101 25 828 A1 a polarity reversal protection for energy sources, in particular for car batteries, known, which is connected between the power source and a generator or a consumer. The polarity reversal protection comprises a sensor,

Power source are connected to the correct terminals of the consumer or the generator, and means for disconnecting the power source, such as a fuse in case of incorrect polarity of the power source.
Beim Tiefentladen von Batterien, insbesondere HV-Batterien, zum Zweck der Sicherung, Befundung und der Entsorgung können einzelne oder mehrere Zellen im seriellen Verbund, bedingt durch Ladezustand oder Kapazitätsunterschiede, umgepolt werden. Derselbe Effekt kann auch bei internen Kurzschlüssen auftreten. Bei ungeschützter Elektronik kann dies zur Beschädigung bis hin zum Brand der gesamten Batterie führen. Somit ist es wünschenswert die an die Batterie angeschlossene Elektronik nicht nur im Fall einer Verpoiung der gesamten Batterie sondern auch im Fall der Umpolung einzelner Batteriezellen zu schützen. When over-discharging batteries, especially HV batteries, for the purposes of backup, diagnosis and disposal single or multiple cells in the serial network, due to state of charge or capacity differences, can be reversed. The same effect can also occur with internal short circuits. With unprotected electronics this can lead to the damage up to the fire of the entire battery. Thus, it is desirable to protect the electronics connected to the battery not only in the case of Verpoiung the entire battery but also in the case of polarity reversal of individual battery cells.
Aufgabe der vorliegenden Erfindung ist es somit, eine Batteriezellenanordnung mit Verpolschutz bereitzustellen, die Schutz vor Beschädigung der Elektronik und eine generell verbesserte Sicherheit der Batterie bietet. The object of the present invention is therefore to provide a battery cell arrangement with polarity reversal protection, which offers protection against damage to the electronics and generally improved safety of the battery.

Beispielweise kann eine Stromumkehr, bedingt durch die Umpolung einer oder mehrerer Batteriezellen oder eines oder mehrerer Zellmodule, verhindert werden, oder der Stromfluss durch die Teilstromkreise der umgepolten Batteriezellen oder Zellenmodule unterbrochen oder von der Zellelektronik entkoppelt werden. Advantageously, the polarity reversal protection can comprise at least one diode and / or at least one fuse and / or at least one electrical switching element and / or at least one mechanical switching element and / or at least one galvanic isolation of at least one battery cell and the cell electronics.
