A modular battery storage system includes energy storage modules. A switch is assigned to individual energy storage modules, by which the respective energy storage module can be activated and deactivated. The energy storage modules can connect to one another by the switches such that the individual voltages of activated energy storage modules can be added up to form a total voltage. A method of operating the battery storage system ascertains at least one power value for each of the energy storage modules, the power value being characteristic of the power capacity of the energy storage module. A total voltage is generated by at least two energy storage modules being activated with a time overlap but over activation periods of different length. One of the activation periods of different length is assigned to each of the at least two energy storage modules depending on the ascertained at least one power value.
