ABSTRACT:
The invention relates to control of a battery, permitting a reduction in the number of components of the battery. The battery comprises several modules (2a, . . . ,2n), each module comprising a charge limiting circuit (4). When a module is detected as defective, the charge limiting circuit (4) carries out a command for the discharge of said defective module, by formation of a short-circuit path. The battery can subsequently be used without functional hindrance by the defective module.
