Battery Cell Unit Comprising a Battery Cell and a Monitoring and Actuation Unit for Monitoring the Battery Cell and Method for Monitoring a Battery Cell

摘要

A battery cell unit includes a battery cell and a monitoring and actuation unit for monitoring the function state of the battery cell. A coupling unit is provided in the battery cell unit, in which coupling unit two half-bridges forming a full-bridge are arranged, which half-bridges each comprise a first power semiconductor coupled to a positive pole of the battery cell, a second power semiconductor coupled to a negative pole of the battery cell and a central connection and are connected to a respective other output terminal of the battery cell unit via the respective central connection. The battery cell is configured to operate, in the normal operating mode, the power semiconductors of the half-bridges in such a way that a battery cell voltage of the battery cell is present at the output terminals of the battery cell unit optionally with a positive or negative orientation.
