A modular battery storage system includes an array of n rechargeable energy storage modules. Each respective energy storage module is assigned a respective switch via which the respective energy storage module can be activated and deactivated. The n rechargeable energy storage modules are configured to be interconnected, via the switches, such that a total voltage UTotal provided by the array of n rechargeable energy storage modules is a sum of respective individual voltages Usingle of activated energy storage modules. The modular battery storage system further includes a controller, configured to control the switches, and a modulator, connected to the n rechargeable energy storage modules and configured to modulate the total voltage UTotal. The modulator includes a pulse width modulation switch. A housing encloses the pulse width modulation switch and is adapted to shield electronic components outside the housing from electromagnetic interference radiation emanating from the pulse width modulation switch.
