    • The invention relates to a method for adjusting a voltage of a DC intermediate circuit in a battery system composed of a battery and a drive system. The battery is connected to the drive system via the DC intermediate circuit and comprises at least one battery module (40, 60) that has a coupling unit (30, 50) and at least one battery cell (11) connected between a first input (31, 51) and a second input (32, 52) of the coupling unit (30, 50). In a first method step, the battery cells (11) of the at least one battery module (40, 60) are decoupled during a first variable time period by emitting a corresponding control signal to the coupling unit (30, 50) of the at least one battery module (40, 60), and the at least one battery module (40, 60) is bridged on the output side so that an output voltage of the battery becomes zero. During a second variable time period, the battery cells of the at least one battery module (40, 60) are again coupled and the bridging on the output side of the at least one battery module (40, 60) is terminated by ending the emission of the corresponding control signal to the coupling unit (30, 50) of the at least one battery module (40, 60) so that a value of the output voltage of the battery is greater than zero. The method steps are repeated until a voltage of the DC intermediate circuit reaches a nominal supply voltage. The invention further relates to a battery which is designed to carry out said method, to a battery system comprising such a battery and to a motor vehicle equipped with such a battery system.
