1. A management process for systems made up of cells electrically connected in series that each include one or more electrical energy storage battery units to form a system for subjection to alternating charge and discharge phases in which each cell is associated with an individual current bypass circuit connected to terminals of said cell and controlled by a controller operating in accordance with indications supplied by a circuit measuring at least one parameter of said cell, said process comprising the steps of:

  • measuring the parameter of each of the cells of the system; and

    providing cell by cell balancing of the system based on said measurements, whereinbalancing is initiated at any time over a time period that covers all operating phases of said system when said system is supplying power to an application, and is provided both during battery charge phases and during idle phases between charging and discharging of said application.
