<p>The method comprises the phases of: acquiring a plurality of pairs of voltage/current values (Vi, Ii); determining a curve (V(I)) interpolating the pairs of voltage/current values (Vi, Ii) which defines a current operative voltage/current characteristic (V(I)) of the storage unit; sub-dividing a graph of the voltage/current characteristics of the storage unit into a plurality of reference windows each associated with a corresponding reference state of charge ( rho 0- rho 8) of the said storage unit; plotting the current operative voltage/current characteristic (V(I)) on the graph of the voltage/current characteristics; identifying, from among the reference windows, a specific reference window containing the current operative voltage/current characteristic (V(I)); determining, from among the reference states of charge ( rho 0- rho 8), a specific reference state of charge ( rho i, rho i+1) associated with the specific reference window identified; and determining the current state of charge ( rho i,k) of the storage unit on the basis of the above-mentioned specific reference state of charge ( rho i, rho i+1). <IMAGE></p> |
