Abstract
A device for balancing charge in a battery (2) having a set of electrochemical storage cells (C1, C2, . . . , CR), and a charging means (R1, . . . , Rs) able to recharge a plurality of combinations of at least one cell, in which for each combination of the plurality of combinations, the charging means are arranged in order to simultaneously recharge all the cells of said combination, the plurality of combinations defining a number N strictly higher than one of combination types, each combination type corresponding to a number m of cells in this combination, and the charging means are permitted to function at a number P of power levels, this number P being strictly lower than the number N of combination types.
