Abstract

A method for AC-charging an intelligent battery pack, which is connected to a charging column and has at least two battery modules, which each comprise at least one energy storage element and at least two power semiconductor switches, which interconnect the respective battery module in series or in parallel with another battery module. The battery pack is connected for charging with alternating current provided by the charging column by a charging circuit, which includes a filter and a rectifier. According to the method, a state of each individual energy storage element is monitored. In accordance with a continued evaluation of the states of the respective energy storage elements, a terminal voltage of the battery pack is adjusted by way of dynamic actuation of the power semiconductor switches to a voltage provided by the rectifier.
