Abstract
A charge current to be supplied to a battery is selected depending on a remaining capacity of the battery to be charged and/or an initial temperature of the battery to be charged. A battery voltage or a battery temperature is being monitored and sampled at a relevant sampling interval determined depending on the selected charge current. A difference between two battery voltages or between two battery temperatures at two sampling points is sequentially computed and whether or not the battery has reached a fully charged condition is determined based on the computed results.
