Abstract
A system of batteries of accumulators includes electrochemical accumulators in series, a power connection connecting either a load or recharging power supply across the accumulators, a control device connected to the accumulators by the power connection, measuring circuits, each of which is attached to a respective accumulator and configured to measure voltage across its terminals, and communication circuits, each of which is attached to an accumulator and configured to induce a voltage drop across its terminals when the measured voltage crosses a threshold. The control device identifies this drop in voltage.
