Abstract
An energy supply system including an electrical energy storage system having multiple storage modules, in particular a battery system, an ascertaining device for ascertaining state variables of the storage modules and an energy transmission device for energy transmission between the storage modules and a downstream electrical device. It is provided that the energy transmission device has multiple d.c. chopper converters, which are connected to one another in parallel and/or in series at the output end, and each of the d.c. chopper converters is connectable to a storage module of the energy storage system, and the energy supply system has a trigger device for triggering the d.c. chopper converters as a function of the ascertained state variable of the respective connected storage module. Also described is a method for operating an energy supply system.
