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.

A process for charging a sealed nickel-cadium storage battery in a time on the order of three to fifteen minutes. Charging is performed at a constant charging voltage which is lower than the voltage at which hydrogen is released at the negative electrode of the storage battery. Charging is terminated when the charging current intensity of the storage battery registers a significant increase following a gradual decrease during the charging process.
