Abstract
A battery charging system for a multi-cell battery charger operative to apply a charging current to one or more battery packs, each comprised of one or more battery cells. Initiation of application of a fast charging current is permitted only when the voltage levels taken across output terminals of a battery pack positioned at the battery charger, and the ambient temperature of such battery pack, is within desired ranges. After initiation of application of the fast charging current, the ranges of voltage and ambient temperature levels within which application the fast charging current is permitted are expanded to prevent termination of application of the fast charging current responsive to transient changes of the temperature and voltage levels.
