Abstract
A method of efficiently recharging a supplementary battery of a vehicle can recharge the supplementary battery with power from a main battery. A method of controlling a supplementary battery recharging system includes: acquiring charged current of a supplementary battery; starting a timer when the charged current exceeds a limit range; updating a current limit on the basis of a timer value and temperature information of the supplementary battery; and controlling a target voltage using the updated current limit.
