Abstract

A method for the switched division of a high-voltage battery of a vehicle, which, for the purpose of charging the high-voltage battery, is connected to a charging column supplying a charging voltage of a specific voltage level, wherein the voltage level of the high-voltage battery results from a number M of series-connected modules of the same rated voltage, wherein the voltage level of the high-voltage battery corresponds to an integer multiple N of the voltage level of the charging voltage of the charging column, wherein the high-voltage battery is subdivided into N parallel-interconnected segments consisting of an equal number of modules by means of a first switch position of a number of power semiconductors.
