Abstract
A vehicle may include a first battery to output power of a first voltage, a second battery to output power of a second voltage, a DC-DC converter to convert the first voltage of the first battery into the second voltage, and to supply the power of the second voltage to the second battery. The DC-DC converter may include a transformer to convert the first voltage into the second voltage, a first switch to control first current input to the transformer from the first battery, a current sensor to measure a value of second current output to the second battery from the transformer, and a controller to turn on/off the first switch based on a set turning-on/off frequency. The controller may delay turning-on/off of the first switch based on the measured value of the second current.
