Abstract
A method of controlling a battery including a first control circuit and a plurality of modules arranged between first and second terminals. Each module comprises electric cells. The battery further includes a sensor of the current flowing through the first terminal. The method includes the successive steps of: updating a first counter representative of the quantity of charges flowing through the first terminal; for each electric cell, for each connection of the electric cell to the other electric cells, storing into first data the value of the first counter on connection of the electric cell and for each disconnection of the electric cell from the other electric cells, storing a second counter equal to the difference between the value of the first counter on disconnection of the electric cell and the first data of said electric cell.
