description	A system for the dynamic evaluation of the state of health and charge of the battery of a vehicle. The system, assembled in the vehicle, measures the electrochemical impedance of a battery by means of: means (5) for generating a sinusoidal alternating current applied to the battery posts; means for measuring the voltage drop caused by the passage of said current; means (2) for filtering and conditioning said voltage drop, and means (3, 10) for obtaining the actual and imaginary components of said electrochemical impedance; comprising a unipolar architecture where the injected signal is an alternating component at only one frequency, coming from an oscillator, continuously superimposed on a reference component, the measurements of the actual and imaginary components being carried out continuously in time together with the acquisition of a voltage proportional to the injected current at all times.
