Method for Adjusting a DC Intermediate Circuit Voltage

摘要

The disclosure 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 that has a coupling unit and at least one battery cell connected between a first input and a second input of the coupling unit. In a first method step, the at least one battery cell of the at least one battery module is decoupled during a first variable time period by emitting a corresponding control signal to the coupling unit of the at least one battery module, and the at least one battery module is bridged on the output side so that an output voltage of the battery becomes zero.
