Abstract: The invention relates to a method for driving the charging and discharging of a plurality of electrical energy storage devices connected to a common connection point (PCC) of an electrical distribution network, as a function of variation of a requested power value (Ptref) at the common connection point, each electrical energy storage device (i) presenting a respective instantaneous state of charge (SOCi), comprising steps of: a—determining a number of electrical energy storage devices needed (Nneeded) to provide the requested power value at a time t, b—activating and/or deactivating one or more of the electrical energy storage devices, as a function of the determined number of electrical energy storage devices needed (Nneeded), and the values of the instantaneous states of charge (SOCi) of each of the electrical energy storage devices (i), and c—distributing the requested power (Ptref) between the activated electrical energy storage devices.
