Abstract: A system comprises an electric battery having at least four elementary cells in series and at least two balancing modules each having first and second nodes connected by at least three cells of the battery, and a third node connected to an intermediate point of the series-association of the at least three cells, in which at least one of the first and second nodes of each module is not common to a first or second node of another module.

Abstract: System for balancing an association in series of elements for generating and/or storing electrical energy has full bridge inverters (OPC1, OPC2, OPCN), with two inverter arms connected in parallel between two end ports and with two switches (Th1, Tb1; Th2, Tb2) connected in series by a median point (P11, P12) of the arm; a plurality of connectors for connecting the two end ports of each full bridge inverter to a respective element (CA1, CA2, CAN, PV1, PV2, PVN) of said association in series; and a magnetic coupler (NM) formed by a magnetic core on which a plurality of windings (W1, W2, WN) is formed, each winding connected to the median points of the arms of one of said inverters. A series of elements (CA1, CA2, CAN) for electrochemical storage of electrical energy and a series of photovoltaic cells (PV1, PV2, PVN) provided with such a balancing system are also disclosed.
