Abstract
The method and the facility are intended for regulating the current supplied by a charger (3) to a set (1) made up of a plurality of units (2), each of which is provided with an individual interface (5) making it possible to measure voltage, to divert a portion of the charging current, when the voltage measured across the unit is greater than a threshold value, and to supply measurement signals to a controller (4) of the charger. The charging current is reduced as soon as one of the interfaces indicates that it is diverting current, and so long as the charging current supplied is greater than the sum of the currents that can be diverted by the interfaces. The charging current is then maintained at the same level until all of the interfaces indicate that they are diverting current.
