Abstract
A system for charging at least one energy reservoir cell in a controllable energy reservoir serving to control/supply electrical energy to an n-phase electrical machine (n≧2). The controllable energy reservoir has n parallel energy supply branches each having at least two series connected energy reservoir modules, each encompassing at least one electrical energy reservoir cell having an associated controllable coupling unit, are connected to a reference bus, and are connected to a respective phase of the machine. As a function of control signals, the coupling units interrupt the respective energy supply branch or bypass the associated reservoir cells or switch the associated reservoir cells into the respective energy supply branch. To charge at least one cell, at least two phases of the machine are connectable via at least one respective free-wheeling diode to a negative pole of a charging device. The reference bus is connectable to the negative pole of the device. Those energy supply branches connected to those phases which are connectable to the negative pole of the device each have a contact point disposed between two energy reservoir modules and is connectable via at least one free-wheeling diode to a positive pole of the device.
