A multi-voltage storage system for an at least partly electrically driven vehicle includes a first storage module and a second storage module having an identical rated voltage for storing electrical energy, wherein on-board consumers are connected to the second storage module at least with priority during a charging process, a heating apparatus for heating the storage modules, a switch unit which is designed to connect the first storage module and the second storage module in series for a charging process and in parallel for driving the vehicle, and a control unit, which is firstly designed to control the switch unit before and/or during a charging process such that the parallel connection of the first storage module and the second storage module is eliminated, and which is secondly designed, after elimination of the parallel connection, to activate the heating apparatus before and/or during the charging process.
