Abstract

A battery management system for a battery module string includes battery modules. The battery modules are electrically connectable to poles of the battery module string and individually electrically disconnectable. The battery module string is configured to generate an AC voltage by disconnecting and connecting the battery modules. The battery management system is configured to assign a respective first time period to each first battery module of the battery modules based on position of each first battery module in a battery module list. Each of the first battery module is electrically connected within a half-cycle of the AC voltage during the respective first time period.
