A battery charging control apparatus for a vehicle generator comprises switching means (39) for controlling a field current flowing through a field winding (13) of the generator intermittently, voltage control means (31) for controlling the switching means (39) to increase the field current gradually in order to maintain a voltage of a battery to be charged at a first predetermined value (VR1) when the battery voltage drops below the first predetermined value (VR1), generator output voltage detecting means (40) for detecting an output voltage of the generator, charging abnormality warning means (46, 47, 48), which detects occurrence of charging abnormality, when the detected generator output voltage drops to assume a second predetermined value (VR2) and below, which value (VR2) is lower than the first predetermined value (VR1), and at the same time the battery voltage remains at the first predetermined value (VR1) and below for a predetermined time, and which then turns on a charging abnormality warning lamp (7), and current increasing means (31, 35, 38, 50) which increases the field current to thereby increase the generator output voltage to assume the second predetermined value (VR2) and above within the predetermined it is made possible to prevent erroneous lighting of the charging abnormality warning lamp (7). <IMAGE> |
