1. A method of controlling an electric system comprising first and second terminals, electric cells, and switches configured to connect or disconnect the cells in series and/or in parallel between the first and second terminals, the method comprising the steps of:
a) determining a first priority table comprising first cell priority levels for a system charge operation and a second priority table comprising second cell priority levels for a system discharge operation;
b) determining data representative of the average current or of the average electric power exchanged by each cell over a time window according to the cell implementation number in a cell connection sequence;
c) determining a classification of at least part of the cell implementation numbers by increasing or decreasing order of the data representative of the average current or of the average electric power;
d) assigning the implementation numbers according to the classification order to the cells by increasing or decreasing order of the priority levels of at least one of the first or second priority tables; and
e) controlling the switches to connect or disconnect the cells according to the order of the assigned implementation numbers.
