Method for fault detection and autonomous reconfiguration of a system comprising an electromechanical converter, capable of detection faults and autonomously reconfiguring itself to ensure post-fault operation with acceptable performance, said system comprising a permanent magnet synchronous motor with open-end windings, said motor comprising three identical groups of phases, each group of phases having five phases, each group of phases having a separate DC voltage source, and each group of phases having an inverter or a static converter with a H-bridge or full-bridge structure, in which method: if a first faulty phase is detected, then this faulty phase is isolated from its group and the four remaining phases of said group are reconfigured, such as to increase their currents to compensate at least in part the lost current of the faulty phase, and/or in which method, if a first faulty DC source is detected, the group to which said faulty DC source belongs is a disabled group, and the currents are increased in the two remaining groups, such as to compensate at least in part the lost current of the disabled group.

The inverter (32) comprises pairs (5, 6; 7, 8) of switches arranged in series on electrical lines (4a, 4b) connecting electrical potentials (2, 3) to a phase line (9) to be supplied by a current formed by incessant switching of the switches. The switches in the pair are redundant to prevent damage caused by a short-circuit in one of the switches, while the other continues to open the line (4), maintaining normal operation. Failure of one switch is detected by a detection circuit while supplying switches of each pair with time offsets.

In a charging station (22) for electric batteries (21), a supply equipment communication controller module (24) monitoring the charging process between the power module (23) and a supervisor module (25) integrates an insulation monitoring device (29) and a manager (19) thereof for repeatedly estimating insulation resistances between the poles (DC+, DC-) of the battery, and the charging conductors (27, 28) with respect to the earth (PE). The device (29) replaces conventional, separate apparatus which must be plugged to the battery and involve cumbersome measurements. In preferred embodiments, the device (29) cooperates with a measurement chain for the voltages of the poles with very little hardware added, which may consist in an electric discharge branch connecting the measurement chain to the earth, and comprising a resistor and a switchable switch.
