A charge control system for a vehicle is provided with a microcomputer which calculates the most suitable battery charging value or voltage regulator set value on the basis of detected engine and charging system parameters. The microcomputer uses parameters such as the charging condition and service life condition of the battery, along with the instantaneous generated voltage, etc., and outputs the calculated set value to the voltage regulator of the charging system.
