The invention relates to a multi-voltage storage system for an at least partly electrically driven vehicle, wherein the storage system comprises - a first storage module and a second storage module having 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, - 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apparatus before and/or during the charging process, wherein the electrical energy demand for the heating apparatus is withdrawn at least with priority from the first storage module (1).
本发明涉及用于至少部分电驱动的车辆的多电压储存器系统,该储存器系统包括:用于储存电能的具有相同的额定电压的第一储存器模块和第二储存器模块,车载电网消耗器在充电过程期间至少优先与第二储存器模块连接;用于加热储存器模块的加热装置;开关单元,其配置用于串联第一储存器模块和第二储存器模块以用于充电过程以及将它们并联以用于驱动车辆;控制单元,该控制单元首先配置用于在充电过程之前和/或期间这样操控开关单元,使得取消第一储存器模块和第二储存器模块的并联,并且该控制单元其次配置用于在取消并联之后在充电过程之前和/或期间激活加热装置,用于加热装置的电能需求至少优先从第一储存器模块(1)中取用。
