  "textContent": "Reduces the discharge of parts (5) of the battery bank (1), so as to balance, by substituting for the minimal step balancing voltage a higher balancing voltage (V1'), from the moment when the battery is no longer fed by the charger (2), from an upper time level to a determined time level (T). Method of balancing a series connected battery bank (1) composed of a number of series connected batteries (5) whose recharge is done by a charger (2) under the control of a battery management system associated with individual current supply modules (6), in parallel with each battery. Each circuit is activated when the voltage at the battery terminals falls below a minimal set balancing level (V1), common for all the batteries. The management system includes a control chain permanently providing an ALL or NOTHING signal, for a current circulating between the battery terminals through a series of transmission control gates (13) each linked to a battery. Each gate is controlled to interrupt the control chain current when the voltage at a battery terminals exceeds a maximum value (V2). All current interruption is translated into a switching control signal transmitted to the charger via a common control interface (7). In this case the minimal balancing voltage (V1) is substituted by a higher balancing voltage (V1') after a time greater than a set time (T) in response to interruption of the current circulating in the control chain. An Independent claim is also included for a battery management system.",
