To efficiently control charging and regenerative control for a secondary battery. A charge control device, including: a calculation unit (voltage sensor (11), current sensor (12), and control unit (10)) that calculates a state of charge of the secondary battery; a detection unit (vehicle state detection unit (20)) that detects a traveling state of the vehicle; and a control unit (control unit (10)) that, when it is detected that the vehicle is decelerating, sets a voltage generated by an alternator higher than the terminal voltage of the secondary battery in order to regeneratively charge the secondary battery, that, when it is detected that that the vehicle is not decelerating, sets the voltage generated by the alternator lower than the terminal voltage of the secondary battery when a state of charge is greater than a prescribed second threshold value, and that sets the voltage generated by the alternator higher than the terminal voltage of the secondary battery when the state of charge is less than a prescribed first threshold value. The second threshold value is greater than the first threshold value, and the first threshold value and the second threshold value are set within a low SOC region.
