Abstract
The invention relates to a method and system for electronic current control for a flexible DC battery pack, in which the battery pack has a plurality of flexibly interconnectable modules having a respective energy store and at least two respective controllable switches and the modules are electrically connected to one another to form a section having a first and a second section end and the two section ends are connected to a respective high-voltage connection, in which the at least two switches of a respective module interrupt a battery current I or interconnect the respective energy store at least in series or parallel with or to bypass the respective energy store of the respectively adjacent module, in which the flexible interconnection of the modules is controlled by a battery control unit and hence a prescribed DC voltage V is provided.
