Abstract

In a method for transferring energy between at least two energy storage cells in a controllable energy store that serves to control and to supply electrical energy to an n-phase electric machine, which energy store has n power supply arms which each have at least two series-connected energy storage modules which each include at least one electrical energy storage cell with an associated controllable coupling unit, and are connected to one respective phase of the electric machine, in a charging phase, all coupling units of those energy storage modules which are to be used as an energy source are controlled in such a way that the respectively associated energy storage cells are connected into the respective power supply arm.
