In a method of charging several electrochemical cellsconnected in series, by a chargerwhich allows adjusting the voltage and the charging current, the voltage of each cell is detected permanently, and when a first cell reaches a predetermined threshold voltage, an increment of the charging current is applied to several cellsand simultaneously a shunt resistor of a current equivalent to the increment in the charging current of the several said cellsis connected in parallel to said first cell, and when each of the subsequent cells reaches the threshold voltage, a shunt resistor of a current equal to the increment in charging current of said several cellsis also connected in parallel to this cell. The invention is applicable to the use of accumulator systems for powering electric vehicles and thermal vehicles with self-contained electric mode.

An emitter assembly of low-power electromagnetic signals with random or pseudo-random frequency variation is located inside an electromagnetic shield to be monitored. These signals are detected by at least one synchronous detection receiver located outside the shield, a second transmission channel, preferably constituted by an optic fiber, connecting the emitter and receiver assemblies to enable synchronous detection of signals transmitted via an electromagnetic channel through the shield. The amplitude of the electromagnetic signals received by the detector is significant of the quality of the shielding.
