Abstract (en)
[origin: WO2012038261A1] A method is introduced for operating a battery with a multiplicity of battery modules (40, 60) which are connected in series. Each battery module (40, 60) has a coupling unit (30, 50) and comprises at least one battery cell (11) which is connected between inputs (31, 51; 32, 52) of the coupling unit (30, 50). In a first step, a defective battery cell (11) and the battery module (40, 60) which contains the defective battery cell (11) are detected. The defective battery cell (11) is subsequently deactivated by outputting a corresponding control signal to the coupling unit (30, 50) of the detected battery module (40, 60), and bypasses the detected battery module (40, 60) on the output side. After a functionally capable battery cell (11) has been coupled to the detected battery module (40, 60), the output-side bypassing of the detected battery module (40, 60) is ended. The invention also relates to a battery which is designed to carry out the method, and to a motor vehicle having such a battery.
