A method for operating a battery system connected to an electric energy system, having battery strings connected in parallel, including a battery, an inverter and a transformer Each battery is chargeable and dischargeable. Each battery has an installed, maximum charge capacity and a capacity that is available in the current operating state. During discharging the currently available capacity corresponds to a state-of-charge of the respective battery, and during charging the currently available capacity corresponds to a difference between the maximum charge capacity and the state-of-charge of the respective battery. A total charge output requested during the charging of the battery system and/or a total discharge output requested during the discharging of the battery system is distributed as part outputs over the battery strings and thus over the batteries dependent on the currently available capacities of the batteries of the battery strings connected in parallel.
