Abstract

The invention relates to a method for detecting anomalies in a battery cell (22), wherein a short-circuit sensor system (20) detects events (44) in a signal of a terminal voltage of the battery cell, which events have successive edges in an interval of time of microseconds, and wherein events detected by the short-circuit sensor system are transmitted to a battery management system (16) which determines anomalies in the battery cells using the detected events. A short-circuit sensor system (20) and a battery system (12) which are set up to carry out the method are also stated.
