ABSTRACT:
A battery charging control apparatus for controlling charging of a secondary battery has a FET which is so controlled that the supply of a charging current is suspended after being forcibly supplied to the secondary battery for a predetermined charging time, when the voltage of the secondary battery has risen to a level equal to or higher than a predetermined reference voltage, and, after the battery voltage has come down to the reference voltage during the suspension of the supply of the charging current, forced supply of the charging current is commenced again, thus realizing intermittent charging. The FET also is so controlled as to vary the above-mentioned charging time in accordance with the progress of charging of the secondary battery.
