Abstract
A method of monitoring rapid charging of sealed nickel storage cells of the nickel-hydride type and of the nickel-cadmium type, said cells optionally being associated in a battery, wherein once said cells have been identified and a relationship for the heating of said cells as a function of charging time for a given charging mode has been determined and stored, the charging of said cells is stopped when the difference between the temperature of said cells and a reference temperature exceeds a predetermined value, the reference temperature being calculated on the basis of said heating relationship and as a function of the charging time that has already elapsed.
