Abstract
A control system for a rechargeable battery comprising at least two electrochemical generators electrically connected by a power line comprises a protection unit and at least two control units respectively connected to the terminals of each electrochemical generator. Each control unit is designed to measure at least one operating parameter pertaining to the said generator and to command the protection unit by transmission of carrier currents on the power line. The control system according to the invention dispenses with the master processor for commanding the battery protection units and reduces the connecting wires by dispensing with the measurement leads designed to transmit the measurements of the operating parameters of each generator to the master processor.
