Abstract

A management process and a corresponding control arrangement are provided for systems made up of cells in series subjected to alternating charge, possibly fast charge, and discharge, possibly deep discharge, phases. Each cell of the system is associated with a current bypass connected to the terminals of that cell and controlled by a control system that operate in accordance with indications supplied by a measuring system individually assigned to the cells. The process provides for balancing, which can be initiated at any time, that is programmed to be used over a time period that can cover all of the various phases of operation of the system, in connection with an application supplied with power by the system, and which is effected cell by cell until balance, in a battery charge phase, in an idle phase between charges by a charger and discharges by the application and/or in discharge phases.
