Abstract

A method for DC-charging an intelligent battery pack, which is connected to a charging column and has at least two battery modules. Each battery module includes at least two power semiconductor switches and at least one energy storage element. The battery pack is connected for charging by way of a connection circuit. A state of each individual energy storage element is monitored, wherein, in accordance with a continued evaluation of the states of the respective energy storage elements, a respective series and/or parallel interconnection of the respective battery modules among one another within the battery pack is configured dynamically by way of actuation of the power semiconductor switches.
