ABSTRACT:
A battery charger which provides a constant current charge during a first part of the charging period and a taper charge during the remainder of the charging period. The taper charge characteristic is obtained by decreasing a set value for the charging current by a step of predetermined size each time the battery voltage has risen by a step of predetermined size, provided that the battery voltage is above a certain threshold; below this threshold, the set value has its maximum value, resulting in the constant current part of the charge. The charging current is regulated to be equal to the set value, regardless of variations in mains supply voltage. The charge is terminated when the time between steps in battery voltage exceeds a predetermined value.
