Abstract (en)

[origin: WO2011064012A2] The invention relates to a battery system, comprising a plurality of battery cells (10), which are connected in series between a first battery pole and a second battery pole, a first relay (11) connected between the first battery pole and a first output of the battery system, a second relay (12) connected between the second battery pole and a second output of the battery system, and a controller. The battery system comprises a third relay (13), which is connected in series with a first resistor (14) having a predetermined size between the first battery pole and the first output of the battery system and is connected in parallel to the first relay (11). The controller is connected to the relays (11, 12, 13) and designed to open or close the relays (11, 12, 13) by means of outputting a respective control signal.
