Abstract
A system for monitoring aging of a battery comprising a plurality of cells connected in series and able to be fully discharged comprises a discharger which discharges one of the previously charged cells at a time to an end of discharge value. The quantity of electricity supplied by each discharged cell during discharging is measured. The quantity of electricity supplied by at least one discharged cell is processed to detect excessive aging of the battery. Excessive aging of the battery results in a residual capacity which is less than a fraction of the nominal capacity of the battery.
