Beschreibung
Zusammenfassung:The invention relates to a battery system (10) for a vehicle or for a stationary energy store, comprising a battery (20). A first of a plurality of battery cells (21, 22) of the battery (20) comprises an electrochemical part, which has a plurality of electrodes and at least one separator, which, upon reaching a first temperature, is impermeable to ions that can be produced in the electrochemical part. The first battery cell (21) comprises a quick discharge unit, which can be connected, by means of a control unit (30) of the battery system (10), between two battery cell terminals of the first battery cell (21), which battery cell terminals can be contacted from inside and/or outside of the first battery cell (21). The quick discharge unit is designed to discharge the first battery cell (21) by means of a first current. A first resistance value of the quick discharge unit is selected in such a way that, while the first current flows through the quick discharge unit and the first battery cell (21), the first current causes such heating of the electrochemical part that the at least one separator reaches the first temperature.
