Abstract

A battery system comprises a battery which includes a plurality of battery cells connected in series and two battery poles. The battery system further comprises at least one protection device, which is connected to the battery cells in series in such a manner that after the at least one protection device is tripped, a sum of voltages of the battery cells still connected in series does not exceed a limit voltage. The battery system also comprises a switching device which electrically connects the two battery poles, the switching device being configured to short-circuit the battery when a fault signal is detected, thus tripping the at least one protection device.
