System for monitoring a set of electrochemical accumulators A1 to An, characterised in that at least a few accumulators are equipped with an autonomous, individual module 2 for measurements, comprising at least one sensor 12, 10 of a parameter characteristic of the state of the accumulator, and a casing 24 containing electronic circuits for measurement, for local processing of the measurements and for serial transmission of information, the general supply to the said circuits coming from the terminals 5, 6 of the accumulator, the information transmitted consisting of a message comprising at least one read-off code for the relevant accumulator and at least one item of information relating to the voltage Ua of the said accumulator and to the parameter captured by the said sensor, the said message being transmitted repeatedly at a random rate distributed around a uniform value, the system including a unit 7 for receiving and exploiting the messages from the various accumulators, the said unit furthermore receiving an item of information regarding the total voltage VE of the set of accumulators and regarding the current I drawn. <IMAGE> |
