The present invention relates to a system for bypassing (10) a pile of electrochemical blocks (3) connected in series. The system includes bypass circuits (27) each connected between a positive pole and a negative pole of an electrochemical block. The system (10) also includes a control circuit (11) provided for sending a control signal to at least one of the bypass circuits in order to ensure the latter bypasses the electrochemical block to which the circuit is connected between the poles of the block. The control system comprises control modules (12), each with its own voltage reference, in which each one of the bypass circuits belongs to one of the modules. Each control module includes a plurality of bypass circuits, the bypass circuits belonging to a control module being connected between the poles of adjacent electrochemical blocks, such that the control modules sub-divide the pile into a plurality of groups (13) of electrochemical blocks. The system is furthermore characterised in that each control module includes a means (23) for communicating with the control circuit, such that the control circuit can control bypass circuits belonging to separate control modules. |
