Claim Text:
1. A method for controlling a traction and/or propulsion chain which includes an electric machine for driving an electric or hybrid motor vehicle which is supplied with electric power by a battery via a control circuit which is associated with an electronic power circuit, the battery having a set of modules each having at least one electric accumulator, the modules being connected in series with each other, the method comprising: commutation of the modules in which each module of the set may be selectively disconnected from the set; calculating energy losses in accordance with common operating characteristics of the traction and/or propulsion chain, for each of a plurality of possible commutation configurations of the modules, respectively; determining at least one optimum commutation configuration of the modules which minimizes the energy losses from the plurality of possible commutation configurations of the modules; and activating the commutation of the modules in accordance with the optimum commutation configuration of the modules which minimizes the energy losses.
