Abstract
The present invention relates to a method for controlling a battery with integrated inverters comprising n basic cell modules (MEk) which supply a basic voltage Vcell and allow the application of a homogenous current to all the cells. More specifically, the method comprises a step of controlling the control signals (uik) from the basic modules (MEk) so as to provide the voltage waveform (VM) on the basis of a selection of a group of q basic modules (MEk) according to a reference voltage setpoint Vref, where Vref=qVcell, determining a classification of the n basic modules, processing the classification of the plurality n according to a circular permutation of the positions of the basic modules (MEk) such that each basic module (MEk) of the plurality n is involved in producing the voltage waveform over a period that is the same for each module. The invention is applicable in the fields of electromobility and stationary energy storage.
