<p>The invention relates to a control device (D) to be associated with a charger (CH) for an electrical battery (BA) of a system (V), said charger having input ports coupled to a charging station (PC) that is connected to a general supply network (RA) providing a main alternating voltage differential, and to the electrical battery (BA) via at least lines (L1, L2). Said device (D) comprises i) measuring means (MM) coupled to at least one of the lines (L1, L2) in order to measure at least first and second values of at least one electrical variable relating to said lines (L1, L2), in the presence respectively of different first and second current consumptions of a set consisting of the charger (CH) and the electrical battery (BA), and ii) processing means (MT) arranged so as to force said set (CH, BA) to carry out the first and second current consumptions, then to estimate a parasite impedance and/or a parasite non-linear effect between the input ports and the general supply network (RA) according to the first and second values and the first and second current consumptions, and to determine a value of the charging current of the electrical battery (BA) according to the estimated parasite impedance and/or the estimated parasite non-linear effect and the main alternating voltage differential.</p> |
