Assembly comprising an electric battery and a battery control system

An assembly comprising a battery (30) of cells (Ei-j) and a storage control system. The battery comprises β branches (BRJ) each having e cells (Ei, j) in series between the positive (P) and negative (N) of the battery, the same row of cells (i) of the different branches (BRJ) defining stages (ETI). The control system includes a circuit (32) connected to the battery terminals, and a diode array (34) connecting the cells (Ei, j) to the circuit (32), the network (34) comprising, for each stage ( eti) with the exception of the stage (Etl) connected to the positive terminal (P) of the battery, β diodes (D1i, j) direct-connected respectively between the positive terminals of the cells of the stage and the same first terminal (VmaxEti) and β diodes (D2i, j) respectively connected in reverse between the positive terminals of the cell floor and one second terminal (VminEti).
