Abstract
The device 1 for the management of a plurality electric battery elements 2 connected in series, comprises a plurality of battery management modules 4, each management module being connected in parallel to the terminals of a respective battery element 2 and supplied by its output voltage, the management modules 4 including a digital circuit 11 and being connected in series by at least a digital liaison 9, 9' so as to exchange binary information between said digital circuit 11 and a control unit 5 of the battery, and is characterized in that at least a capacitor 8, 8' is connected in series on said digital liaison 9, 9' so that the binary information may be exchanged between each management module 4 and the unit control 5, independently of the electric potentials at the terminals of the battery elements 2.
